Description

LIFTING POTENCY, DEVICE FOR INSTALLING SUCH A POTENCY ON A CONTAINER, CAMPAIGN WORKSHOP AND METHOD FOR INSTALLING A CAMPAIGN WORKSHOP INCORPORATING SUCH A POTENCY

The technical field of the invention is that of lifting cranes, their installation devices and field workshops with containers equipped with lifting cranes.

It is known from the patent WO2013 / 150172 a field workshop comprising a crane disposed on a pair of transport containers, type 20 feet sea containers. This crane comprises a pair of guide rails longitudinally disposed each on one of the containers.

Each of these rails is intended to serve as a guide to the rolling of sommiers located at each end of a lifting beam. The beam is equipped with a hoist of high capacity which can be translated along this beam. In this way, the crane can lift and move heavy loads, up to 20 tons, in the space between the containers.

The elements constituting a crane of this capacity, in particular the lifting beam, are themselves massive (1 to 3 tons) and very bulky (4 to 10 meters) which requires significant lifting means of the mobile crane type , with pedals and slings, to be installed on the containers.

When using a campaign, for example in a theater of military operations where the available means are limited, the use of a crane is a heavy handicap, unfavorable to the deployment of such a crane.

Also known from US6042328 a light vehicle having a rear body (vehicle "pick-up"), bucket which carries a means to easily land a charge out of the vehicle. This means comprises an L-shaped arm which pivots between a folded position along the vehicle body and an unfolded position in which the arm extends towards the rear of the vehicle and can place the load on the ground. This lightweight means is not suitable for the establishment of a lifting bracket on a transport container.

The invention aims to provide a bracket that is easily installable independently by a team of field mechanics.

The invention also relates to a campaign workshop made using containers with such lifting cranes, workshop can be equipped with a crane as described above, without the use of a crane or means of important lifting.

Advantageously, the invention provides complementary lifting means.

Advantageously, the boom comprises a hoist slidable along the boom. Advantageously, the shaft is of a length greater than the height of a container on which the bracket is intended to be fixed. The invention also relates to a device adapted to install such a lifting crane on a container, characterized in that it comprises a frame comprising a wheeled transport trolley adapted to support and transport at least one folded bracket, chassis comprising a soleplate intended to be able to cooperate with the pivot interface of the foot of a bracket to be put in place, and at least one pivoting actuator fixed to the frame and intended to be removably fixed at the shaft of the bracket to implement, the actuator can pass the stem of the stem from a horizontal position to a vertical position by pivoting the foot on the sole, the pivot interface also having a removable axis to separate the sole of the foot a the gallows attached to the container.

Advantageously, the device may comprise a wedge intended to be positioned between a container and the carriage.

The invention also relates to a transport container characterized in that it comprises at least one lifting bracket according to at least one of the above characteristics.

Advantageously, at least one bracket is secured to a side face of the container.

According to another embodiment, a bracket is integral with an end face of the container.

The invention also relates to a field workshop comprising at least two transport containers according to the invention, containers arranged parallel to one another and symmetrically with respect to a median plane, containers for each receiving at their upper face a guide rail of a bed base of a lifting beam and its supports to form a traveling crane, the two containers each carrying at least one bracket disposed at symmetrical faces by ratio to the median plane.

The invention finally also relates to a method of installing such a campaign workshop, characterized in that it comprises the following steps:

at least two transport containers are positioned in the field, parallel to each other and symmetrically with respect to a median plane;

each of these two containers is fixed, and with the aid of an installation device according to the invention, a bracket on symmetrical faces of the container with respect to the median plane.

Advantageously, the method also comprises the following steps:

- Each rail support is placed on the ground in the vicinity of a container and is hoisted with the hoist of a bracket to the top of the container where it is put in place;

each running rail of the overhead crane is placed on the ground in the vicinity of a container and is hoisted by means of the hoist of a bracket to the top of the container where it is put in place;

each bed frame of the crane is placed on the ground in the vicinity of a container and is hoisted by means of a hoist of a bracket to be positioned on a rail; the lifting beam is disposed on the ground near the containers in an area accessible to the hoists of the brackets and is hoisted to the top of the containers where each end of the beam is secured to the sommiers.

The invention will be better understood on reading the following description, description made with reference to the appended drawings, drawings in which:

Figure 7 shows a top view of the third phase of installation of a crane of a field workshop according to the invention and according to a second embodiment of the method.

Figure 8 shows a partial side view of a container equipped with a bracket according to a variant of one invention. According to Figure 1, a container 100 of the shipping container type as defined by the International Organization for Standardization (ISO) under ISO 668 and ISO 1496, is placed on the ground. Opposite a face 101 located at one end of the container 100 is a device 1 for installing a lifting bracket 3 according to the invention (or device adapted to install a bracket 3 according to the invention).

The installation device 1 comprises a frame 2 comprising a carriage 2 on wheels on which rests, in substantially horizontal position, a lifting bracket 3. The installation device 1 is placed at a distance D from the end face 101 of the container 100.

For easier positioning of the installation device 1 relative to this face 101, a shim 104, of length identical to the distance D, is placed between the installation device 1 and the container 100.

The chassis 2 comprises a sole 5 which is solidarisable, with a pivot interface 6a carried by a foot 6 of the bracket 3.

The pivot interface 6a may include a removable axis for example. The foot 6 of the bracket 3 is located at a second end 7b, said lower end of a shaft 7 of the bracket 3. At least one actuator 8 pivoting, such as a hydraulic cylinder 8 for example, connects the 7 to the frame 2 of the installation device 1. This actuator 8 is fixed by one end 8a to a support 12 secured to the frame 2 and by its other end 8b to a yoke 13 secured to the shaft 7 of the bracket. Of course, this fixing on the yoke 13 is carried out with the aid of a removable shaft in order to allow the barrel 7 to be released from the bracket 3 once it is fixed to the container 100.

It will be noted that the bracket 3 is foldable and which comprises, at a first end 7a or end upper barrel 7, an arrow 9 which is folded along the shaft 7. The boom 9 is thus hinged relative to the barrel at an upper fork 15 carrying an axis 16 transverse to the fork 15.

The fork 15 of the boom 9 is connected to the shaft 7 by a pivot connection of known type, so as to allow, once the bracket is installed, the pivoting of the boom 9 in a plane about an axis 17 parallel to the direction longitudinal drum 7.

A single bracket 3 is visible in Figure 1, but it is advantageous to have two brackets 3, side by side on the same installation device 1, for convenience and to reduce cost and space.

The skilled person will dimension the device 1 so that the brackets 3 on the installation device 1 hold integrally in a container 100, thus facilitating the transport of the device 1 in one of the containers 100 constituting a campaign workshop.

According to FIG. 2, the pivoting actuator 8 is activated by means of a power unit 14 and causes the foot 6 of the stem 3, and therefore of the bracket 3, to pivot progressively about the pivot interface 6a, and relative to the sole 5 so that the bracket 3 passes from the horizontal position to a substantially vertical position in which it is applied against the end face 101 of the container 100 as visible in Figure 3.

Note that to have such a positioning against the face 101, the skilled person will choose the distance D separating the face 101 and the pivoting means 2 depending on the distance L between the sole 5 of the part of the stem 6 called to stand against the face 101.

Furthermore, the frame 2 is defined so that, after the pivoting of the shaft 7 of the bracket 3, the foot 6 of the bracket is positioned substantially at ground level. The distance between the ground and the removable axis of the pivot interface 6a is thus substantially equal to the distance between the axis of the bore of the foot 6 receiving this pivot axis and the underside of the foot 6. In practice this distance between the ground and the removable axis of the interface 6a is of the order of 80 mm to 100 mm. According to Figure 3, once the bracket 3 is in the vertical position, the shaft 7 is secured to the edges of the container 100 by solidarisâtion means such as flanges 10. Ideally, the flanges 10 can hang on the interfaces standard hoist 102 existing on the shipping containers (interfaces 102 visible in Figure 2). The flanges 10 will be fixed to a collar 18 integral with the barrel 7.

Advantageously, this solidarity will be achieved before separating the bracket 3 and the installation device 1. The separation of the bracket 3 and the installation device 1 is done by removing the removable pins of the pivot interface 6a and the clevis 13.

In the event that the device 1 is used with non-standard containers, it is within the reach of the skilled person to fix the barrel 7 on the face 101 or on its edges by any means of solidarity dismountable of its convenience .

Once these solidarisâtion steps performed, the arrow 9 can be unfolded and placed substantially horizontally. If necessary, a strut 19 strengthens and ensures the maintenance of the arrow 9 in a horizontal position. This strut 19 is fixed to a pivoting collar 20 so as to allow the pivoting of the boom 9 about the axis 17 of the pivot of the fork 15.

It should be noted that to avoid an unfolding effort of the arrow 9 too important, this unfolding step can be performed when the bracket 9 is in a position of intermediate pivoting such as the position illustrated in Figure 2.

A hoist 11 is placed on the boom 9, hoist 11 slidable along the arrow 9.

Note that the shaft 7 is longer than the height of a container 100 in order to hoist part of the crane elements 200 above the container 100.

Thus, a rail 201 (FIG. 3) can be hoisted on an upper face of the container 100 to be fixed along the length of the container 100 on supports 201a integral with the container 100 and be equipped with a bed base 202 able to roll along this rail 201.

Once a first bracket 3 has been installed and the crane elements 200 (rail 201 and box spring 202) are put in place and fixed on the upper face of a first container 100, the previous operations are repeated at a second container 100. which will be arranged parallel to the first and symmetrically with respect to a median plane P (Figure 4).

Thus, as can be seen in FIGS. 4 to 6b, a pair of containers 100 arranged parallel and at a distance from one another are equipped with brackets 3 arranged at symmetrical faces with respect to the median plane P. Each container 100 comprises on its upper face a rail 201 placed on supports 201a and a bed base 202.

According to FIGS. 4 and 6a, a lifting beam 203 is placed on the ground with each of its ends in an area accessible to the hoists 11. As can be seen in FIG. 5, the beam 202 is progressively and simultaneously hoisted by each of the hoists 11 of to be kept substantially horizontal for reasons of stability.

An intermediate step of fixing a winch 205 will be performed at man's height before finishing the hoisting of the beam 203. According to FIG. 6b, the arrows 9 of each bracket 3 are turned progressively and simultaneously so as to place the beam 203 on the sommiers 202 and perpendicularly to the rails 201 in order to be fixed on the bed bases 202. The skilled person will take guard when the arrows 9 rotate, the hoists are always placed vertically of the beam 203 by sliding the hoists 11 according to the positioning needs to not create a point of stress generating instability.

It will be advantageous to provide each bracket with motorization means (not shown) for controlling the pivot of the arrows 9. Other motorization means are also associated with the hoists 11.

According to FIG. 7 and according to another embodiment and installation, each bracket 3 is fixed on a lateral face 103 of a container 100, which advantageously makes it possible to release the opening of doors 110 situated on the end faces 101 of the containers 100 (FIGS. 4 and 5).

Note that in the case of Figure 7, the lifting beam 203 has a length that exceeds the distance between the drums 7 of the two brackets 3 which prevents the passage of the beam 203 between the drums 7 and perpendicular to the rails 201.

In such a case, after hoisting the beam 203 beyond the height of the sommiers 202, the skilled person will put the beam 203 in place above the containers by passing it between the barrels 7, c ' that is to say by passing one end of the beam 203 between the barrels 7 before the other end. Once the two ends passed between the drums 7, the beam 203 is placed perpendicular to the rails 201 to be fixed as in Figure 6b.

Still with the aim of providing a light means of installation of a campaign workshop, the skilled person will dimension at most just the gallows 3 and hoists 11 in function of the heavier half-load constituted by the beam 203 with its winch 205.

In this way and as an example if we consider that the crane has a lifting capacity of 16 tons which requires a beam of a mass of 2 tons with winch, brackets 3 and hoists 11 to ensure a lifting of one ton each will suffice (with the safety coefficients close), which gives 3 equipped gallows weighing a few hundred kilos each.

The device thus has a footprint and masses much lower than those of traditional heavy lifting means such as a construction crane or a freight elevator vehicle. The invention thus provides a great autonomy of installation to the staff of the campaign workshop.

The invention therefore makes it possible to install a crane over containers without resorting to a crane or heavy lifting means.

Advantageously, the invention provides, thanks to the two brackets 3, additional lightweight lifting means for a campaign campaign on containers.

This last point makes it possible to specify that the person skilled in the art wishing to equip a single container with a light lifting means and not needing lifting beyond the height of the container 100 may use a bracket 3 according to the invention. whose height of the barrel 7 does not exceed the height of the container 100 as shown in FIG. 8.
