All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in figures 1 to 6, the invention provides a lifting device comprising a folding standing platform, which comprises a base 1 and two door frames 7, wherein the left bottom ends of the two door frames 7 are fixedly connected with the right side of the base 1, the bottom end of the base 1 is movably provided with two large wheels 2, the front side and the rear side of the top of the base 1 are fixedly provided with telescopic frames 3, the two telescopic frames 3 are movably connected through a movable shaft, the movable shaft at the highest position between the two telescopic frames 3 is movably provided with a hydraulic rod 11, the bottom end of the hydraulic rod 11 is movably arranged at the right bottom of the telescopic frame 3, the top of the telescopic frame 3 is fixedly provided with a standing platform 4, one side of the top of the standing platform 4 is fixedly provided with a control platform 5, the periphery of the standing platform 4 is fixedly provided with a fence 6, the right bottom ends of the right sides of the two door frames 7 are fixedly provided with a bottom plate 17, the, the equal fixed mounting in inner wall of two portal 7 has fixed block 701, the equal fixed mounting in top of two fixed blocks 701 has chain 703, two chain 703 clockwise windings are on sprocket 702, the inner wall fixed connection of sprocket 702 and portal 7, two chain 703 anticlockwise windings are on sprocket 704 No. two, the sliding tray has been seted up to the inner wall of portal 7, and the inside at the sliding tray is connected to both ends activity joint around sprocket 704 No. two, the equal fixed mounting of two chain 703 other ends is at the surface of gyro wheel 13, the equal fixed mounting in both ends about two-way motor 12 of two gyro wheels 13, the right side fixed mounting of two-way motor 12 has two forks back 8, the right side fixed mounting of two forks back 8 has fork 9.

Wherein, rail 6 includes bracing piece 603, and the quantity of railing 604 is two, the bottom of two bracing pieces 603 with stand 4 fixed connection, and the equal fixedly connected with railing 604 in top, have dodge gate 602 through hinge 601 movable mounting between two railings 604, can make the staff get into the platform of standing more convenient while not losing the security through installation dodge gate 602 again.

Wherein, base 1 left side fixedly connected with counter weight box 16, counter weight 14 has been placed to counter weight box 16's inside, because the weight of load goods is different, so can change counter weight 14 inside counter weight box 16 according to the weight of goods.

Wherein the front ends of the forks 9 are inclined downwards, the bottoms of the front ends of the forks 9 are flush with the bottoms of the small wheels 10, the goods are generally placed on the ground, so that the forks 9 are required to pick up the goods from the ground, and the fork 9 is advantageously low to be flush with the bottoms of the small wheels 10 at the lowest level so as to pick up the goods on the ground.

Wherein, holding tank 15 has been seted up at the middle part of fork 9 lower half, and holding tank 15's size and dolly wheel 10's size looks adaptation because of the reason of the goods of need following ground shovel.

When the bidirectional motor 12 rotates clockwise, the dual-fork backrest 8 is in a rising state, and when the bidirectional motor 12 rotates counterclockwise, the dual-fork backrest 8 is in a falling state.

The working principle and the using process of the invention are as follows:

firstly, a worker opens the movable door 602 upwards to enter the standing platform, then closes the movable door again, then walks to the front of the control platform 5 on the standing platform 4, starts to control the lifting device to move back and forth to the front of the goods through the control platform 5 (the control platform controls the integral lifting device which is the prior art and is not described in detail herein), then operates the fork 9 to insert into the bottom end of the goods, operates the lifting device to move to a specified place after forking, starts to operate the two-way motor 12 to drive the roller 13 to rotate after reaching the place, because one end of the chain 703 is fixed at the fixed block 701, the other end of the chain 703 is fixedly arranged inside the roller 13, the roller 13 rotates to wind the chain 703 to drive the double-fork backrest 8 to slowly rise, and the double-fork backrest 8 is connected with the fork 9 to drive the goods to rise immediately, and because the view of the worker begins to become poor due to the rise of, so the hydraulic stem 11 of the top of base 1 top of will operating simultaneously this moment drives whole expansion bracket 3 and rises to the bright height in field of vision can, because of the reason that has rail 6 moreover, the staff can hand and do not worry dangers such as falling in railing department.
