A rotating plate 67 is provided below the reverse threaded rod 65. One end of the rotating plate 67 is rotatably connected to the second rod sleeve 66, and the other end of the rotating plate 67 is rotatably connected to a second connecting block 68.

There are two ways to fix the connection: bolt connection and welding. In this application, bolt connection is preferred.

[0041] In the embodiment, the protection mechanism 6 is arranged to improve the stability of the large storage shelf as a whole, and to reduce the possibility of the large storage shelf falling to a certain extent, thereby avoiding the damage of goods falling to the materials and the occurrence of the staff being injured by the falling goods. The connecting pipe 64 is arranged between the forward threaded rod 63 and the reverse threaded rod 65, and the forward threaded rod 63 and the reverse threaded rod 65 are both threadedly connected with the connecting pipe 64. Due to the arrangement of the opposite direction structure of the threads on the outer surfaces of the forward threaded rod 63 and the reverse threaded rod 65, when the staff rotates the connecting pipe 64, the forward threaded rod 63 and the reverse threaded rod 65 are simultaneously extended out of the connecting pipe 64 or simultaneously retracted into the connecting pipe 64. The first connecting block 61 and the second connecting block 68 are both bolted on one side of the shelf column 1. The forward threaded rod 63 is rotationally connected with the first connecting block 61 through the first rod sleeve 62. The reverse threaded rod 65 is rotationally connected with the rotating plate 67 through the second rod sleeve 66. The rotating plate 67 is rotationally connected with the second connecting block 68. Therefore, when the forward threaded rod 63 and the reverse threaded rod 65 are simultaneously extended out of the connecting pipe 64, the rotating plate 67 below the two is driven to rotate until the rotating plate 67 assists the shelf column 1 to support the ground. The threadedly connected stability between the forward threaded rod 63, the reverse threaded rod 65 and the connecting pipe 64 is better, and it is more conducive to improving the stability of the large storage shelf as a whole.

[0042] Working principle:

[0043] As Figures 1-8When the worker uses the device to lift the goods, the position of the hook 83 is adjusted according to the specific position of the goods to be lifted, first, the worker starts the second motor 51 to change the position of the hook 83 in the horizontal direction, after the second motor 51 is started, the output end of the second motor 51 drives the second threaded rod 52 to rotate, the second threaded rod 52 drives the main gear 53 connected thereto to rotate, while the main gear 53 rotates, the auxiliary gear 54 drives the secondary gear 55 to rotate synchronously, the secondary gear 55 rotates to drive the third threaded rod 56 connected thereto to rotate, so that the second threaded rod 52 and the third threaded rod 56 rotate synchronously, because the sliding plate 43 is simultaneously limited to rotate by the inner wall of the clamping groove opened at the top of the connecting frame 3 and the second threaded rod 52 and the third threaded rod 56, the sliding plate 43 connected with the second threaded rod 52 and the third threaded rod 56 in the screw thread is moved inside the clamping groove opened at the top of the connecting frame 3, at the same time, the sliding plate 43 and the clamping pipe 44 are moved along the rotating rod 42, cooperating with the first threaded rod 49 and the sliding block 402, so that the sliding plate 43 drives the hook 83 to move in the horizontal direction, secondly, the worker starts the first motor 41 to adjust the position of the hook 83 in the other horizontal direction according to the specific position of the goods to be lifted, after the first motor 41 is started, the output end of the first motor 41 drives the rotating rod 42 connected thereto to rotate, the rotating rod 42 drives the clamping pipe 44 connected thereto to rotate through the clamping groove opened on the outer surface, the clamping pipe 44 drives the worm 47 connected thereto to rotate, the worm 47 drives the worm wheel 48 connected therewith in meshing transmission to rotate, the worm wheel 48 drives the first threaded rod 49 connected thereto to rotate, because the clamping groove opened at the top of the sliding plate 43 limits the rotation of the sliding block 402, so that when the first threaded rod 49 rotates, the sliding block 402 connected with the first threaded rod 49 in the screw thread moves inside the clamping groove opened at the top of the sliding plate 43, so when the sliding block 402 moves, the hook 83 moves in the other horizontal direction, when the hook 83 is placed above the center of the goods, the worker starts the electric winch 81, cooperating with the connecting rope 82 to realize the lifting of the hook 83 to lift the goods, finally, the protection mechanism 6 improves the stability of the whole large storage shelf, the worker rotates the connecting pipe 64, because the threads on the outer surfaces of the forward threaded rod 63 and the reverse threaded rod 65 are opposite, the forward threaded rod 63 and the reverse threaded rod 65 simultaneously extend out of the connecting pipe 64 at the same time to drive the lower rotating plate 67 to rotate, so that the rotating plate 67 can assist the shelf column 1 to support the ground, at this time, the worker stops rotating the connecting pipe 64.
