The final combination of the forces generates a resultant force vector in any required direction by depending on the direction and the speed of the respective wheels, so that the platform can move freely in the direction of the final resultant force vector without changing the direction of the wheels, and the device is suitable for ship environments with limited transfer space and narrow operation channels, has obvious effects in improving ship guarantee efficiency, increasing ship space utilization rate and reducing labor cost, greatly improves the applicable sites of the device, and expands the application range.

Referring to fig. 2, 4 and 5, a telescopic bottom beam 1 is disposed between a first moving beam 2 and a second moving beam 16, a supporting plate 5 is pinned above the first moving beam 2 and the second moving beam 16 by a rotating diagonal brace 3, two sets of vertical plates 36 are disposed on the upper surface of the supporting plate 5, a wire paying-off roller 6 is rotatably mounted between the vertical plates 36, and a wire rope 7 is pulled out from the surface of the wire paying-off roller 6 and sequentially attached to and driven in a wheel groove of a traction wheel 11. In the embodiment, a group of support plates 5 are arranged, four groups of paying-off rollers 6 are symmetrically arranged at the top of the support plates 5, steel wire ropes 7 are wound on the surfaces of the paying-off rollers 6, symmetrical rotary inclined struts 3 are arranged at the bottoms of the support plates 5 and are respectively connected with a first movable beam 2 and a second movable beam 16, movable assemblies 17 are arranged at the bottoms of the first movable beam 2 and the second movable beam 16, and when the rotary inclined struts are particularly used, a motor 21 is started to drive a driving gear 18 to drive a first driven gear 19 to rotate so as to drive a third pin shaft 46 to rotate in a second lug plate 33, so that the rotary inclined struts 3 are driven to rotate, the support plates 5 fall, and the included angle between the two groups of rotary inclined struts 3 is increased; the supporting plate 5 is lifted, the included angle between the two groups of rotating inclined struts 3 is reduced, the lifting of the supporting plate 5 is realized by utilizing the motor 21, and the lifting device is applicable to building profiles to be lifted with different sizes.

As shown in fig. 8 and 9, two rotary diagonal braces 3 are hinged to a second ear plate 33 provided at the lower part of one end of the support plate 5 through the upper end, and two rotary diagonal braces 3 are respectively hinged to both ends of the telescopic bottom beam 1 through the lower end; a screw shaft 13 is vertically and rotatably arranged in the middle of the end part of the supporting plate 5, which is close to the rotary diagonal bracing 3; the upper end of the screw rod shaft 13 is connected with the output end of the motor 21 through a bevel gear, and the screw rod shaft 13 is connected with a sliding sleeve 14; the middle parts of the two rotary inclined struts 3 are hinged with the sliding sleeve through a connecting plate 23; and when the motor 21 is started positively, the motor 21 can drive the screw shaft 13 to rotate so as to drive the sliding sleeve to vertically move along the axial direction of the screw shaft 13, and in the process of vertically moving the sliding sleeve, the rotating diagonal bracing 3 can be driven to mutually close or spread around the second lug plate 33 through the connecting plate 23 so as to realize lifting and lowering of the height of the supporting plate 5.

It can be appreciated that the conventional hoisting device is fixed in position for installing the paying-off roller when hoisting materials, so that the paying-off roller needs to release a longer length of the pull rope when hoisting objects. It should be appreciated by those skilled in the art that the longer the pull cord, the more likely it will shake during lifting of the object, which may result in the object being bumped or jolted. Therefore, in order to improve the safety of the traditional lifting device, the technical scheme of the utility model can reduce the supporting plate 5 provided with the wire placing roller along with the lowering of the pull rope or lift the supporting plate along with the winding of the pull rope during lifting, so that the length of the pull rope which is required to extend out of the lifting device during lifting an object can be effectively shortened, and the safety of the lifting device is improved.

Therefore, in order to ensure the normal operation of the device, when the supporting plate 5 is required to be positioned at the lowest position, the paying-off roller 6 just finishes paying-off until the pneumatic clamping jaw 12 is positioned at the lowest position; when the support plate 5 is in the uppermost position, the payout roller 6 just completes spooling until the pneumatic clamping jaw 12 is in the uppermost position.

It will be appreciated that the paying-off roller 6 may be set to rotate N1 turns during the whole paying-off process, and in this process, the number of turns of the screw shaft 13 is N2 when the sliding sleeve slides between two extreme positions, so that the transmission ratio between the paying-off roller 6 and the screw shaft 13 is N1/N2. Assuming that n2=30 and n1=60, the transmission ratio of the first bevel gear to the second bevel gear is 2, and the common mechanical design can be satisfied, so that the condition that the transmission ratio is too large to be realized is avoided. And the entire lifting and lowering process of the support plate 5 in the above process does not interfere with the payout roller 6.

It can also be understood that assuming that the limit movement interval of the support plate 5 in the vertical direction is X, the maximum payout length of the conventional payout roller is Y; the maximum payoff length required by the scheme of the utility model is Y-X.

It will be appreciated that by guiding the pull cord through the traction wheel 11, the length of the pull cord (pull cord between the pneumatic jaw 12 to the traction wheel 11) over which the swing can occur can be further reduced. In order to ensure that the pneumatic clamping jaw 12 is always in a lifting stable state in the process of moving up or moving down, the traction wheel 11 arranged on the moving block 9 needs to synchronously move along with the pneumatic clamping jaw 12, so that the moving block 9 is driven to move by arranging the ball screw 8, and the same driving source is adopted for driving the ball screw 8 and the paying-off roller 6, so that the synergy between the two can be effectively ensured.

Specifically, assuming that the number of turns required for the ball screw 8 is N3 when the moving block 9 moves between two extreme positions, in order to ensure that the moving block 9 can be synchronized with the pneumatic clamping jaw 12, the transmission ratio between the ball screw 8 and the pay-off roll 6 needs to be ensured to be N3/N1.
