[0025] The present utility model provides a lifting device for railway logistics loading and unloading as shown in Figures 1 - 5 and includes:

[0026] A U-shaped frame 1, support seats 7 are symmetrically arranged on both sides of the U-shaped frame 1, and a lifting platform 11 is arranged inside the U-shaped frame 1. Sliding cavities 8 are opened in both support seats 7, sliders 9 are slidably connected in the sliding cavities 8, support arms 10 are symmetrically arranged on both sides of the support seats 7, one end of the support arm 10 is connected to the slider 9, and the other end of the support arm 10 is connected to the lifting platform 11. A driving component is arranged in one of the support seats 7, and a support component is arranged in the other support seat 7;

[0027] The driving component includes a threaded rod 12 rotatably connected in the sliding cavity 8 through a bearing, the slider 9 is threadedly engaged outside the threaded rod 12, the top end of the threaded rod 12 extends to the support seat 7 and is connected to a first motor 13, and the first motor 13 is fixedly connected to the support seat 7.

[0028] When in use, the first motor 13 can be used to drive the threaded rod 12 to rotate, so that the threaded rod 12 drives the slider 9 to slide in the sliding cavity 8. Then, the slider 9 can drive the support arm 10 to move. With the cooperation of multiple groups of support arms 10, the lifting platform 11 can be driven to lift smoothly in the U-shaped frame 1, and then the railway logistics goods can be lifted and loaded and unloaded through the lifting platform 11.

[0029] The support assembly includes a guide rod 14 fixedly connected in the sliding cavity 8, and the slider 9 is slidably sleeved outside the guide rod 14. The slider 9 can be supported and limited by the guide rod 14 to further improve the stability of the slider 9 moving in the support seat 7.

[0030] A storage cavity 15 is formed in the lifting platform 11. A movable plate 16 is inserted in the storage cavity 15. A plurality of guide rollers 17 are embedded in the top side of the movable plate 16 through a rotating shaft, and one end of the movable plate 16 extends outside the storage cavity 15 and is connected with a guide plate 18.

[0031] One end inside the storage cavity 15 is rotatably connected with a bidirectional screw rod 19 through a bearing. Movable blocks 20 are symmetrically arranged at both ends of the bidirectional screw rod 19. Connecting rods 21 are symmetrically hinged between the two movable blocks 20 and the movable plate 16. A second motor 22 is fixed at one end of the lifting platform 11, and the output end of the second motor 22 is connected with the bidirectional screw rod 19.

[0032] When lifting and loading and unloading, the second motor 22 can be used to drive the bidirectional screw rod 19 to rotate, so that the bidirectional screw rod 19 drives the two movable blocks 20 to move synchronously away from each other. Then, the movable blocks 20 can drive the connecting rods 21 to rotate, so that the connecting rods 21 push the movable plate 16 to slide in the storage cavity 15. After that, the movable plate 16 can extend out of the lifting platform 11. The extended movable plate 16 can greatly make up for the distance between the lifting platform 11 and the cargo box. And through the cooperation of the guide rollers 17 and the guide plate 18, the goods on the lifting platform 11 can be smoothly pushed into the cargo box, or the goods in the cargo box can be smoothly pushed onto the lifting platform 11 without lifting and moving, greatly improving the convenience when loading and unloading goods.

[0033] Limit blocks 23 are symmetrically fixed at both ends of the movable plate 16, and limiting grooves 24 matching the limit blocks 23 are formed on both sides inside the storage cavity 15. By arranging the limit blocks 23 and the limiting grooves 24, the movable plate 16 can be guided and limited, thus greatly ensuring the stable movement of the movable plate 16.

[0034] In a specific embodiment of the present utility model, universal wheels 2 are arranged at four ends of the bottom of the U-shaped frame 1, and a positioning component is arranged on the U-shaped frame 1.

[0035] The positioning component includes fixing plates 3 fixed on four sides of the bottom end of the U-shaped frame 1. Studs 4 are connected through the fixing plates 3 in a threaded manner. A fixed handle 5 is fixed at the top end of the stud 4, and a positioning block 6 is connected to the bottom end of the stud 4.

[0036] The device can be conveniently moved through the universal wheels 2. By rotating the fixed handle 5, the fixed handle 5 drives the stud 4 to move on the fixed plate 3, and then the stud 4 can drive the positioning block 6 to move, so that the positioning block 6 abuts against the ground, thereby stabilizing the device on the ground and greatly ensuring the stability during the lifting operation.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
