Description

MULTIPURPOSE LIFTING DEVICE

The invention concerns to handling equipment and can be used in different branches of industry in order to move large cargo in the only plane, for example, to raise something to level of pier or lower watercrafts (boats, yachts, and so on), rising from bottom of basin the working surface, which can be used as a platform, for example, for dancing, for lifting and lowering cargo in warehouse sheds, as well as vertical goods movement on condition of presence of four independent attachment nodes.

The closest technical essence of this invention, which is claimed, is a hydraulic Boatlift (see. United States Patent No7,066,683 B2 Fig. 3, 4, 1 1, 12) comprising a load platform and a load platform moving mechanism that comprises a power hydrocylinder which piston rod is attached to movable clip, rope wiring and combination of units, each of them is made in form of mounted on wheel axes with a rounded trough, enveloping by rope wiring, which free ends are intended for attachment to outer nodes.

The main disadvantage of its closest analog is the inability to provide its horizontal position by vertical movement of the platform.

It is quite clear that the power hydrocylinder is fastened at the pier, when releasing or hiding (retraction) of the piston rod of the hydrocylinder, the blocks do not engage into work at the same time, so the rope wiring sags, and the load platform raises or lowers being at the angle to the horizontal plane, and the angle may be increased by the movement of the load platform.

In this case, it is necessary to remove sagging of rope wiring which deteriorates the performance of the hydraulic Boatlift.

Another important disadvantage of the closest analog is the presence on edge of pier a power hydrocylinder piston rod of which is attached to the movable holder, as well as to few blocks, enveloping by rope wiring. It is clear that when embarking or disembarking people from the watercrafts it is necessary to be careful and not to be injured, or use a protection frame that will be placed above the end of pier which also deteriorates the performance characteristics of the Boatlift. The basis of the invention is to improve the well-known hydraulic Boat lift, through implementation of a new load platform, new placement and fixation of power hydrocylinder and a new combination and placement of blocks, as well as implementation of a new rope wiring which will improve the performance and extend the functionality of the lifting device.

The assigned task achieves due to the fact that load platform is formed of central and two lateral sections, forming an H-like frame, with a power hydrocylinder positioned along the longitudinal central axis of the profile and fastened to the central profile, wherein on the movable holder along the longitudinal axis central profile mounted first row of the two rollers of different diameter, mounted on the vertical axis, wherein at the end site of the central profile beside the piston rod's power hydrocylinder fixed vertical rod transversely to the central longitudinal axis of the profile mounted the second row of three rollers, mounted on the vertical axes, and at the end of the central profile beside fastening of power hydrocylinder, transversely to the longitudinal axis of the central profile mounted in the third row of the two wheels mounted on vertical axes, wherein on the ends of the lateral profiles mounted wheels, mounted on horizontal axes, parallel to the longitudinal axis central profile, wherein the wiring is made of the lower and upper ropes, which are connected by hinges with vertical rod, wherein the upper wiring of the rope is passed through the upper trough of smaller diameter roller of the first row, upper troughs of the first and second rollers of the second row, the trough of the first wheel of the left side profile, free end of which is intended for fastening on the coincident outer node, wherein the other part of the upper rope is passed through the upper roller of the larger diameter trough of the first row, the third upper roller of trough of the second row, the trough of the second wheel of the left side profile, free end of which is designed for mounting on the coincident outer node, wherein the lower part of the rope is passed through the trough lower roller of smaller diameter of the first row, the lower troughs of the first and middle rollers of the second row, the first trough of the third row of the wheels, the trough of the first wheel of the right side profile, free end of which is designed for mounting on the coincident outer node, wherein the other part of the lower rope is passed through the lower roller of larger diameter trough of the first row, the lower trough of the third roller of the second row, the trough of the second wheel of the third row, the trough of the second wheel of the third row, the trough of the second wheel of the right side profile, free end of which is intended for attachment to coincident outer node.

In order to use the lifting device as a Boatlift device on load platform, directing lodgement must be fastened for watercraft placement. It is quite clear that the attachment of power hydrocy Under in the central part of load platform, rollers and wheels mounting on load platform, allows hiding or releasing piston rod hvdrocylinder (accordingly raising and lowering load platform) included in all blocks at the same time (rollers and wheels), due to this sagging of rope wiring does not happen by vertical movement of load platform, saving its horizontal position which improves performance of the lifting device.

In addition, because of mounting of the rollers and wheels on load platform, there are no any coming-out parts and nods on the end of the pier, and this fact provides the safe people embarking or disembarking at the watercraft that also improves performance of the lifting device.

It must be particularly noticed that the claimed lifting device has a possibility of a widerange usage.

Various variants of working surfaces can be set on load platform.

Design feature of the lifting device, namely, that movement mechanism of load platform is mounted on load platform, and free ends of rope wiring being in operating position are fixed on the four outer nodes of attachment, allows the device to be mounted above the basin water surface, for example, a platform for dancing.

For this purpose, power hydrocylinder of load platform is connected by nozzles with oil-pump station, working surface is attached to load platform which shape is identical to the shape of basin water surface, load platform is submerged to basin bottom, free ends of rope wiring are attached to four nodes which are located on the basin walls closer to the upper edge. Then the oil is fed to coincident cavity of the hydrocylinder, when hiding (retraction) of the hydrocylinder piston rod, lifting of the load platform occurs with subsequent fixation of working surface above the basin water surface. Working surface provides a cover, protecting basin from falling debris, and can also be used as a platform for dancing.

It must be noted that if necessary, working surface can be mounted on load platform with required area and shape, and free ends of rope wiring can be fixed on warehouse shed's ceiling beams, for example, in this case the lifting device may be used as an elevator for vertical movement of cargo with a subsequent installation on racks and shelves.

Fig. 1 , 2, 3).

Power hydrocylinder 5 is positioned along the longitudinal central axis of the central profile 2 and fixed on the central profile 2 (Fig. 1, 2, 3).

On movable holder 7 along the longitudinal axis of the central profile 1 1 , the first row of rollers of different diameters is mounted which mounted on vertical axes (Fig. 3, 4, 5, 6).

At the end of the central profile 2 beside the piston rod, the vertical rod is fixed 12 (Fig. 1 , 2, 3) and transversely to the longitudinal central axis of the profile the second row of three rollers 13 is mounted which mounted on vertical axes (Fig. 3, 4, 5, 6).

At the end of the central profile beside fixture of the power hydrocylinder 5 transversely to the longitudinal axis of the central profile 14, the third row of two wheels is mounted which mounted on vertical axes (Fig. 3, 4, 6).

At the ends of the left side profile 3 first wheel 15 and second wheel 16 are mounted, and at the ends of the right side profile 4 the first wheel 17 and second wheel 18 are mounted which are mounted on horizontal axes parallel to the central longitudinal axis of the profile (Fig. 1 , 3, 4, 5, 6).

Upper rope 9 and lower rope 10 by means of loops are connected with the vertical rod 12 (Fig. 1 , 2, 3, 4, 5, 6).

Part of the rope is passed through the upper trough of the roller of smaller diameter of the first row 1 1, the upper troughs of the middle and the first roller of the second row 13, the trough of the first wheel 15 of the left side profile 3, the free end of which is intended for attachment to coincident outer node. Another part of the upper rope 9 is passed through the upper trough of the roller of larger diameter of the first row 1 1 , the upper trough of the third roller of the second row 13, the trough 16 of the second wheel of the left side profile 3, the free end of which is intended for attachment to coincident outer node hinge (Fig. 3, 4, 5).

Part of the lower rope 10 is passed through the lower trough of the roller of smaller diameter of the first row 1 L the lower trough of the middle and the first rollers of the first row 13, the trough of the first wheel of the third row 14 and trough 17 of the first wheel of the right side profile 4, free end of which is intended for attachment to coincident outer node. The other part of the lower rope 10 is passed through the lower trough of larger diameter of the first row 11 , the lower trough of the third roller 13 of the second row, the trough of the second wheel of the third row 14 and the trough of the second wheel 18 of the right side profile 4 (Fig. 3, 4, 6). Multipurpose lifting device works as follows.

For applying the multipurpose lifting device as a ship lifting device, directing lodgement for watercraft placement are fastened on load platform 1 (Fig. 7). Next, work chambers of power hydrocylinder are connected by means of the nozzles with oil-pump station (Fig. Not shown). The free ends of rope wiring 8 are attached to four outer nodes, generally two outer nodes are located closer to two end sites of two piles that are submerged to the bottom of water area, and the other two ones are located on the pier walls closer to the upper edge (Fig. Not shown). Then, load platform 1 is set to the desired depth in water area. After placing the watercraft in directing lodgement, oil flow is fed into the chamber for hiding the piston rod 6 of the power hydrocylinder 5. According to the kinematic diagram (Fig. 4, 5, 6), load platform 1 starts moving (the vertical movement upwards), followed by fixation at the upper edge of the pier. When feeding the oil to the chamber for releasing the piston rod 6 of the hydrocylinder 5, load platform 1 starts moving in vertical direction downwards, followed by fixation.

Fasteners of the power hydrocylinder 5 in the central part of the load platform 1 , and mounting of the rollers and wheels on load platform allows, while raising or lowering load platform, to eliminate sagging of rope wiring 8. This happens due to the fact that at the beginning of movement of piston rod, all the rollers and wheels start to spin together at the same time (Fig. 4, 5, 6).

Due to the fact that there is no sagging of the rope wiring, while vertical movement of load platform, its horizontal placement remains that improves performance of the lifting device.

Furthermore, as on load platform a load platform moving mechanism is mounted, there are no any rotating rollers or wheels on end of the pier, or hydrocylinder piston rod attached to moving holder, which allows safe people embarking or disembarking from the watercraft, which also improves performance of the lifting device.

For applying the multipurpose lifting device as a lifting device for installation above the basin water surface, for example, dancing floor, etc. on load platform 1 working surface is set (Fig. 8) which shape is identical to the shape of water surface of basin. Power hydrocylinder 5 of load platform 1 is connected to oil-pump station. The load platform is submerged to the bottom of basin. The free ends of rope wiring 8 are attached to the four outer nodes which are located on walls of basin closer to the upper edge (Fig. Not shown).

Next, the oil flow is fed into the chamber for hiding the piston rod 6 of the power hydrocylinder 5. In accordance with the kinematic scheme (Fig. 4, 5, 6), load platform 1 performs a vertical movement upwards, followed by working surface fixation above basin water surface. Working surface can be stopped at any level, to provide a shallow depth, for example, for children bathing, or it can be used as a platform for dancing, etc.

It must be noted that at relatively small area, adjoining to basin, two nozzles of relatively small diameter will be placed which connect the chambers of power hydrocylinder to oil-pump station that will not cause any inconvenience by placing people on working surface that improves performance of the lifting device.

A new application expands the functionality of the lifting device.

It must be noted that the constructive features of the claimed lifting device, namely, that moving mechanism is mounted on the load platform and for its functioning, four outer attachment nodes of load platform fixture are required, the lifting device can be used as an elevator for vertical movement of cargo, for example, in warehouse sheds. In this case, outer hinge nodes can be located on warehouse shed's ceiling beams.

The new application of the lifting device also expands its functionality and it can be affirmed that the claimed lifting device is a multipurpose lifting device.
