Description

The invention relates to a screed assembly with a workplace according to the preamble of claim 1. Such an arrangement is known from JP 2005 248576 A named. For the installation of road surfaces screeds are used in practice. The screed is pulled by a paver, is distributed from the Gutbunker by means of a conveyor paving material in front of the screed for shoring.

Conventionally, individual functions of the screed are regulated from the driver's cab of the paver. For example, different working parameters can be set on the components of the screed from the driver's cab. Alternatively, the functions of the screed can be controlled by means of a control unit which is attached to the side of the screed. The staff usually operates the control unit while it runs alongside the screed during installation, or from a catwalk, which is mounted transversely behind the screed on the screed frame. From there, however, a flawless control of the control unit is almost impossible and the staff must concentrate on several things at the same time, which can lead to accidents. In addition, the staff to operate the attached to the screed control unit comes very close to the work area of the screed, where accidents at work can never be completely ruled out.

In fact, the catwalk is not intended as a workplace for a longer stay on it, for example, to control from there, the control unit. Namely, the catwalk should primarily allow the operating personnel to cross the freshly installed road surface without thereby stepping on the hot, possibly still uncomplicated inserted material, which could lead to undesired impressions.

However, because the operators previously used the catwalk for a longer stay on it, in particular to control the control unit and from there to observe the installation, posing for the operator certain risks. Above all, the catwalk offers only a narrow transition, from which one can easily slip off, especially in rainy weather. In addition, it is only possible to carry out a self-limited operation of the operating unit from the catwalk only for small types of screed.

The object of the present invention is to provide a screed arrangement which improves the occupational safety for the operating personnel and ensures optimized installation, wherein in particular the installation of a new road surface can be carried out by means of the screed arrangement such that there are fewer health risks for the Operator comes.

This object is achieved by a screed assembly having the features of claim 1. Advantageous developments of the invention are specified in the subclaims.

The operating staff can therefore spend a long time comfortably on the workstation to observe the installation from there and control if necessary, without causing health risks for the operating personnel. In addition, the vibration-decoupled workplace provides a secure location on the screed assembly where sensitive equipment, such as gauges, can be stored and stored.

Vibrations are speed-dependent oscillations by moving components of the screed arrangement as well as impacts, leveling movements or other adjusting movements of the screed arrangement.

In the invention, the work station is attached to a side shifter of the screed assembly to be associated with an outer region of the working width. The side slider is an especially mechanically or hydraulically (height) adjustable unit, which is attached to the lateral boundary of the working width respectively at outer ends of the screed assembly. Since in most screed arrangements, the basic structure of the respective sideshift is essentially the same, regardless of whether it is a rigid screed assembly, a screed assembly with broadening parts or a screed assembly with pull-out parts, the workplace and its attachment to the side slide screed type cross-spanning uniform, resulting in cost savings in manufacturing.

In addition, from the point of the sideshift from the work station attached thereto, the outer area of a freshly installed pavement can be well seen, which is particularly advantageous in impact-to-collision work, i.e. when pavements are made parallel to each other. Furthermore, numerous control functions of the screed assembly can be well controlled from this point. For example, from there, an operating unit, which is attached laterally to the screed assembly, primarily on the side shifter, are controlled, for example, to set temperatures at components or vibration speeds of compressor components of the screed assembly.

It is particularly advantageous if the workstation is fastened to a side slide carrier of the side slide, for example flanged or welded on. The side sill carrier extends substantially horizontally along lateral ends of the screed assembly, with a height-adjustable side pusher plate being supported inwardly of the screed assembly. The side slide carrier forms a sturdy base for attaching the workstation. In addition, the attachment of the workplace on the side slide carrier has the significant advantage that it can be structurally identical in all Bohlentypen, and that the natural vibration of the side sash regardless of the set working width of the screed assembly is essentially immutable, so that the vibration isolation of the workplace at this point particularly reliable can be guaranteed and can be adjusted well.

It is expedient if the workplace comprises a fastening unit, by which it is preferably releasably attached to the screed assembly, in particular the side slide carrier. The mounting unit also allows the workstation to be retrofitted to a screed assembly of any type, and that the workstation can arbitrarily switch between different screed types.

In a further advantageous variant of the invention, the fastening unit comprises a vibration decoupling unit. This reduces vibrations or even prevents vibrations from being transmitted to the workplace. The thus vibration-decoupled workplace therefore provides a place for the operating personnel, where it over longer Spend time, for example, over eight hours, without taking health-related risks.

Preferably, the vibration decoupling unit comprises at least one mass-spring system and / or a shock absorber. The mass-spring system, in particular, can keep away from the workstation speed-related vibrations of movable components of the screed assembly, which leads to a quiet position or seat of the operating personnel on the workstation. The shock absorber can dampen shocks that may occur, for example, when starting the paver, when crossing bumps or when leveling the screed assembly.

It is also conceivable that the shock absorber of the vibration decoupling unit is automatically reversibly adjustable in order to bring the workplace always in a desired starting position. Preferably, this is a closed liquid spring, which, so to speak, is easy to install and to maintain as a closed unit. Alternatively, a hydraulic shock absorber would be used, which is connected to an existing hydraulic system of the screed assembly. Expedient, in particular cost-effective, however, is also the use of a mechanical shock absorber and / or a gas pressure shock absorber.

According to an advantageous embodiment, the mass-spring system can be biased between the workstation and the screed assembly to thereby set a desired hardness therein. The degree of hardness of the mass-spring system can thereby be individually adapted to different heavy operators.

The vibration decoupling unit is particularly user-friendly when a preload force of the mass-spring system can be set manually and / or automatically. A manual adjustment could be realized, for example, by a screw design, by means of which the workstation is screwed against the natural extension of the mass-spring system. An automated solution could include, for example, an electric motor as a drive, which presses the workplace to a desired biasing force against the expansion of the mass-spring system by its activation. It would also be conceivable to functionally couple the operation of the electric motor to a weight detection system, wherein the electric motor, the biasing force automatically adjusts to the mass-spring system in response to a detected weight of the operator on the workstation.

According to an advantageous variant of the invention, the shock absorber has a variable damping hardness. This could be realized, for example, by adjusting the displacement volume of a damper fluid per unit of time. Similar to the mass-spring system, the damping hardness could also be manually and / or automatically adjustable to allow the operator a maximum individualization of the workplace.

It is particularly advantageous if the fastening unit comprises a swinging bearing, which is mounted on the screed assembly and the workplace hingedly coupled thereto, wherein the workplace is movable by means of the swing bearing between a stowage position and a working position is particularly advantageous. Depending on requirements, this can be used to fold out the workplace or, in particular, to bring it into the stowed position for transporting the screed assembly. According to the invention, the screed assembly in addition to the workplace on a catwalk for the operator on which the operator can also cross the working width during installation behind the screed assembly. According to the invention, the workstation comprises a preferably height-adjustable floor panel on which the operator can stand securely, with the catwalk extending along a larger area of the working width of the screed assembly than the floorboard of the workstation. Preferably, the bottom plate seen in the direction of work to a greater depth than the catwalk, so that the operator can stay on it safely for a long time. To prevent tripping, the bottom plate is arranged substantially at the same height as the catwalk. Seen from the rear, the base plate of the workplace therefore looks like an extension of the catwalk.

Alternatively, however, the bottom plate could also be arranged at a higher level than the catwalk, which may result in better Einsehmöglichkeiten in the installation and the screed assembly for the operator located on the workstation.

A particularly compact embodiment of the invention provides that the bottom plate is arranged in alignment with the catwalk, that is, that the bottom plate in series with the Catwalk is arranged and substantially the same depth as the catwalk comprises. This may be particularly advantageous for the transport of the screed assembly, because the bottom plate of the workplace does not protrude further back than the catwalk. In addition, particularly few edges and corners between the bottom plate and the catwalk are formed, which could trigger the operator.

The workplace can be set up particularly conveniently for the operator when the workplace comprises a seat, in particular a height-adjustable seat. The comfort could be further increased by the air-suspension of the seat.

For use in bad weather, the workplace is particularly well if it is equipped with a weather roof. However, the weather roof also acts as a shade dispenser, so that the operator is not exposed to the blazing sun on the workplace in fine weather.

Preferably, a control unit for controlling functions of the workstation, for example, the height adjustment of the bottom plate and / or the respective degrees of hardness of the mass-spring system and / or the shock absorber, and / or the screed assembly is installed on the workplace. The vibration-decoupled workplace provides a safe place for storage and trouble-free operation of the sensitive and expensive operating unit. By means of the control unit, for example, the leveling of the screed assembly, a tamper speed, temperatures of the heating elements and / or the working width can be adjusted in a Ausziehbohlenanordnung. Warning signals can also be output by the operating unit in order to warn the operator on the paver or to indicate to the operator that he should change a parameter of the installation run, for example a delivery volume of the deposit. The operating unit can also have a display on which current setting parameters of the screed arrangement can be displayed.

Furthermore, it is possible for the operating unit provided on the workstation to be functionally connected to an electronic measuring unit which is fastened to the screed arrangement or directly to the workstation. The measuring unit can be designed, for example, to measure laterally of the screed assembly a distance to the surface, ie to the ground on which the paver moves. With regard to this distance, for example, the leveling of the screed assembly can be automated or a layer thickness of the newly laid road surface can be calculated. If the measuring unit is mounted on the vibration-decoupled workstation, then the measurement result could be improved. In addition, no harmful shocks would be transmitted to the measuring unit there.

It is also expedient if a collision protection unit is arranged on the workstation which can be used to record objects approaching the workstation. In particular, the collision protection unit can be designed such that it determines the distance from a workstation to a rolling vehicle traveling behind, and that as soon as it approaches too close to the workstation it issues warning signals itself or via the optionally connected control unit. These signals can be formed either acoustically or visually.

Particularly comfortable, the workplace is then designed for the operator, if he also has a suction unit, which is designed for the extraction of vapors of the road surface to be incorporated. The suction unit can either be designed independently or connected to a suction unit already assigned to the screed arrangement. In particular, the suction unit is designed such that it directs the ascending vapors below the bottom plate to the rear behind the workplace and / or collects the rising vapors and promotes them via a planned exhaust duct over the roof of the paver and / or the workplace.

For night work, it is helpful if the workplace includes a lighting unit, primarily to illuminate the workstation itself and the outer area of the working width. The lighting unit helps the operator in particular when entering or leaving the workplace and to control the control unit.

The workplace can be made even more comfortable by having an air conditioning unit, in particular a heating and / or cooling unit formed thereon. This allows the operator to cool or heat the workplace depending on the weather. According to a preferred embodiment, the above-mentioned seat of the workplace is tempered with it.

Suitably, the workplace or at least its essential structure is releasably attached to the screed assembly so that it disassembles overnight from the screed assembly can be used to protect the units installed thereon, such as the control unit or the measuring unit, from theft.

Particularly advantageously, the workplace can be used on a screed assembly, which is designed as a Ausziehbohle. This comprises in particular a main and Ausziehteile which are adjustable relative to the main beam sideways to the working direction to vary the working width infinitely. The workstation is preferably mounted vibration-decoupled on one of the pull-out parts, in particular on the side slide carrier of an extension part. It is thus possible to adjust the work space together with the pull-out sideways relative to the main screed, so that the workplace is always assigned regardless of the set working width the outer region of the newly installed road-surface covering. In addition, on the side slide carrier of the pull-out part, essentially the same natural vibration behavior is always present, independently of the adjusted working width, so that the workstation can be reliably stored there in a vibration-decoupled manner. At this point, the installation, measurements and also the control of other functions of the screed arrangement can be monitored well.

It is also conceivable that in each case a workstation is fastened vibration-decoupled at both Ausziehteilen the Ausziehbohle, the respective jobs can match in their construction and their function. Customized, however, the respective workstations can be equipped with different functions.

According to a further embodiment of the invention, the screed assembly is a widenable screed assembly with a main screed and selectively thereto laterally attachable widening parts to increase the working width, the work is mounted vibration-decoupled at one or both widening parts.

The advantages described above can be exploited particularly well when the screed assembly according to the invention is attached to a self-propelled paver.

FIG. 1 shows a side view of a paver 100 with an attached screed assembly 1. The screed assembly 1 is pulled by the paver 100 on a planum 2 in the direction R to produce a new road surface 3. The road surface 3 consists in particular of a bituminous material.

The screed assembly 1 has a main screed 4, which is attached via a pull arm 5 on the chassis of the paver 100. In the working direction R seen outside the main screed 4, a side pusher 6 is attached. The side slider 6 forms a limit for the working width W (see FIG. 5 ) of the pavement 3 to be installed and prevents that before the screed assembly 1 distributed mounting material is pushed past the screed assembly 1 side. The side slider 6 is attached to the main board 4 by means of a side slider support 7. Adjusting modules 8, by means of which the height of a side slide plate 35 attached thereto of the side slide 6 relative to the side slide carrier 7 and to the main pile 4 can be adjusted, are fastened to the side slide carrier 7. The adjustment modules 8 can be mechanically or hydraulically adjustable.

Next shows FIG. 1 in that a vibration-decoupled workplace 9 is fastened on the rear of the side slide carrier 7. The work station 9 occupies an area behind the main screed 4 and offers the operator the opportunity to stand or sit on it for a long time (see FIG. 2 ), in particular to observe the shoring of the road surface 3 in an outer working area of the screed assembly 1. The workplace 9 is flanged to attachment points 10 of the side slider 7.

The workplace 9 further has a fastening unit 11, by means of which the work station 9 is attached to the side slide carrier 7. The fastening unit 11 has a vibration decoupling unit 12, which is designed to prevent vibrations from the screed assembly 1, in particular from the side shifter 6, being transmitted to the work station 9. The vibration decoupling unit 12 is arranged between two fixing plates 13a, 13b of the fastening unit 11 arranged perpendicular to one another. The seen in the direction R front mounting plate 13a is connected to a flange plate 36 shown in dashed lines, which is flanged on an inner side of the side slider support 7 by means of suitable fastening means to the attachment points 10. The rear mounting plate 13b, viewed in the direction of movement R, holds a substantially horizontally mounted bottom plate 14 of the workstation 9. The bottom plate 14 offers the operating personnel sufficient space to stand on it and to stay for a longer period of time.

In the FIG. 1 The vibration decoupling unit 12 has a mass-spring system 12a and a shock absorber 12b. The mass-spring system 12a prevents natural oscillations of the sideshift 6 from being transmitted to the workstation 9. The shock absorber 12b absorbs shocks by the screed assembly 1.

FIG. 2 shows in side view the workplace 9 as a seat workplace. The vibration decoupling unit 12 is in this case of the front mounting plate 13a seen in the working direction R. FIG. 1 solved. For quick release and securing the workplace 9, a quick mounting system 36a, 36b is attached to the mass-spring system 12a and to the shock absorber 12b. On the bottom plate 14, a seat 15 is arranged. In the working direction R seen in front of the seat 15, a control unit 16 is positioned. The operating unit 16 is supported by a holder 17, which is mounted on the bottom plate 14. The operating unit 16 is thus also vibration-decoupled stored at the workplace 9.

On the bottom plate 14, a suction unit 18 is further formed, which is designed for the extraction of vapors of the newly installed pavement 3. The suction unit 18 can be connected to an existing exhaust system of the paver 100, in order to extract vapors from the working area of the screed assembly 1. Alternatively, the suction unit 18 as an independent unit at the workplace 9 for Suction of the vapors, in particular from the outer region of the screed assembly 1, be formed.

Rear of the bottom plate 14 a collision protection unit 19 is further arranged. The collision protection unit 19 is designed to detect an environment relative to the workstation 9 in order to issue an alarm signal either by itself or the operating unit 16 when an object, for example a trailing roller vehicle, comes too close to the workstation 9.

In the FIG. 2 is also a heating / cooling unit 20 can be seen, which is attached to the bottom plate 14. The heating / cooling unit 20 can be controlled by the operating unit 16, wherein it can also be designed to automatically regulate the cooling / heating power as a function of the ambient temperature of the workstation 9. In particular, the heating / cooling unit 20 may be designed to temper the foot area of the workstation 9 and / or the installed seat 15.

For improved work safety, the workplace 9 comprises according to FIG. 2 a frame 21 with a hinged door brace 22. When an operator P (see FIG FIG. 3 ) the workplace 9 according to FIG. 2 If he wants to enter, he should fold the door brace 22 up or down. If he is on the seat 15, then he should for safety's sake, the door brace 22 in the horizontal position shown in accordance with FIG. 2 bring. The frame 21 may also provide attachment options for attaching a tarp or cover that can be attached as a windshield on the frame 21.

FIG. 3 shows the workplace 9 in side view FIG. 2 without the seat 15 and the frame 21, wherein the operator P stands on a tread element 23 of the work station 9, which is arranged on the bottom plate 14. The tread element 23 could, for example, be a rubber mat, in particular with a friction profile, so that the operator P can stand on the workstation 9 in a non-slip manner and also has a pleasant, soft stand on it. The vibration decoupling could thereby be improved for the operator P if the tread element 21 is made of a shock absorbing material, for example of a cushioning polyurethane.

Next shows FIG. 3 a lighting unit 24 which is fixed to the bracket 17 for illuminating the work station 9. The luminous intensity of the illumination unit 24 can preferably be regulated by means of the control unit 16.

The respective components of the in the FIGS. 2 and 3 shown workplace 9 can be combined with each other on customer request. For example, it is conceivable that the in FIG. 3 shown standing workstation with a frame 21 FIG. 2 Is provided. Just as well, the tread element 23 could also on the bottom plate 14 of the in FIG. 2 be shown seated workplace. All jobs 9 according to FIGS. 2 and 3 However, they have in common that they and the components installed on it vibration-decoupled to the screed assembly 1 can be fastened.

FIG. 4 shows in the direction R from a perspective behind the screed assembly 1 schematically the positioning of the work station 9 relative to a catwalk 25 which is fixed to the main screed 4 of the screed assembly 1. The catwalk 25 normally extends substantially the full width of the main plank 4 and allows the operator P to walk around behind the plank assembly 1 without stepping on the newly installed pavement 3.

How to get in FIG. 4 can recognize well, the catwalk 25 is formed indented in the outer region of the screed assembly 1, so that it does not extend beyond the entire working width W behind the screed assembly 1. At this outer area, where the catwalk 25 according to FIG. 4 is no longer trained, there is the workplace 9, the bottom plate 14 occupies substantially the recessed area of the catwalk 25 and is at the same height as the catwalk 25.

As already in the FIG. 1 represented, workplace 9 is also in FIG. 4 attached to the side slider 7. Because the bottom plate 14 according to FIG. 4 Located at the same height level as the catwalk 25, the workplace 9 can also be well from the catwalk 25 and vice versa. In addition, such a height-adjusted positioning of the bottom plate 14 to the catwalk 25 results in a coherent appearance, the bottom plate 14 seen from the rear as an extension of the catwalk 25 acts.

In the FIG. 4 extends through the main screed 4 through a dashed line 26, which is intended to indicate that in the FIG. 4 shown screed assembly 1 as Ausziehbohle Z can be formed. The Ausziehbohle Z would therefore Ausziehteile 27, which are adjustable relative to the main beam 4 sideways in Ausziehrichtung B to extend the working width W of the screed assembly 1 infinitely. By an adjustment of the pull-out 27 in FIG. 4 relative to the main screed 4, the work station 9 moves with the pull-out 27 to the outside, whereby the bottom plate 14 away from the catwalk 25. How to get in the FIG. 4 can see, an extension 28 is fixed to the bottom plate 14, which projects telescopically into the catwalk 25. In a sideways outward movement of the Ausziehteils 27, therefore, the extension 28 moves out of the catwalk 25 to close the resulting between the bottom plate 14 and the catwalk 25 gap.

Even if the in FIG. 4 shown plank assembly 1 is shown as Ausziehbohle Z, this could just as well be designed as a rigid screed assembly 1, which optionally only the main screed 4 and the side-mounted work station 9, or alternatively from the main screed 4 and widening parts 27 'exist, which on the main screed 4 are fortified to expand the work area W. Although the widening parts 27 'do not allow continuous widening of the working area W, as is possible by means of the pull-out parts 27 of the pull-out screed Z, they can fix the work station 9 on the side slide carrier 7 formed thereon as well.

FIG. 5 shows the screed assembly 1 from a point of view according to FIG. 4 , wherein the bottom plate 14 of the work station 9 is disposed over an outer portion of the catwalk 25. The catwalk 25 extends over the entire working width W. As well as in the FIG. 4 is the workplace 9 according to FIG. 5 attached to the side slide carrier 7. The embodiment according to FIG. 5 may arise in particular when the workstation 9 on a paver, ie retrofitted to the screed assembly 1.

Nonetheless, both the FIG. 4 as well as the FIG. 5 that the workplace 9 is within each of the in FIG. 5 indicated working width W is located and does not protrude beyond the side slide carrier 7.

FIG. 6 In side view shows a variant embodiment, according to which the fastening unit 11 has a swing bearing 30 and a biasable buffer 31. The swing bearing 30 and the biasable buffer 31 are between the attachment plates 13a, 13b arranged. The oscillating bearing 30 optionally comprises a spring element 32, by means of which the workstation 9 can be brought more easily into an upwardly folded stowed position. The damping hardness of the prestressable buffer 31 can be adjusted by a biasing force F, so that the workstation 9 can be adapted to the weight of the operator P in a user-specific manner.

FIG. 7 in side view shows a space-saving stowable variant of the workplace 9, which is adjustable between a working position and a jam position. In this case, the bottom plate 14 between a substantially horizontal, unfolded position in which it is in the working position, and a vertical, folded-up position in which it is in the stowed position, are moved. The bottom plate 14 rotates about a radial bearing 33, which fixes the bottom plate 14 to the rear mounting plate 13b of the work station 9 as viewed in the working direction R. In the stowed position, the bottom plate 14 abuts against the rear attachment plate 13b, whereby the work station 9 can be reduced to a minimal amount of congestion.

The workstation 9 according to the invention can be fastened in a vibration-decoupled manner to all known plank arrangements, whether on a rigid screed, a pull-out screed or on widening parts of a rigid screed. For the operator P, this results in a comfortable workstation 9, from which he can perform different functions, for example leveling functions, measuring functions and / or adjustments of the working width of the screed assembly 1. The workplace 9 can be retrofitted to existing screed arrangements 1 or arranged individually according to customer requirements relative to the catwalk 25.

The workplace 9 according to the invention offers a new comfort module, as it has not been used on road pavers, especially on a screed assembly. In addition to the additional comfort for the operator, the workstation 9 also makes it possible to store sensitive and expensive operating instruments, for example the operating unit 16, in a vibration-decoupled manner so that these instruments can be better protected and remain operational for longer.
