[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 3 In an embodiment of the utility model, a guide rail profile lifting device for elevator production includes an axial sliding seat 1 sliding on the guide rail, a cylinder 2 is installed on the outer wall of the axial sliding seat 1, an output end of the cylinder 2 is connected to a vertical sliding seat 3, and a transmission mechanism 4 is provided on the vertical sliding seat 3;

[0031] The transmission mechanism 4 includes a clamping unit and a transmission unit;

[0032] The clamping unit is used to automatically clamp and release the elevator profile;

[0033] The transmission unit is used to provide power for the clamping of the clamping unit;

[0034] The transmission unit includes a connecting rod 401, a rack 403, a gear 404, a force-bearing rod 405, and a stop block 406;

[0035] The connecting rod 401 is axially slidably mounted on the top of the vertical sliding seat 3, and the connecting rod 401 is used to synchronously drive the rack 403 to move;

[0036] The rack 403 is fixed to the outer wall of the connecting rod 401 and is used to provide rotational thrust to the gear 404;

[0037] The gear 404 is rotatably mounted on the top of the vertical sliding seat 3, and the gear 404 is used to drive the other rack 403 to move axially;

[0038] The force rod 405 is fixed to the top of the rack 403 and is used to receive the thrust from the stop block 406;

[0039] The block 406 is fixed on a vertical pole connected to the ground, and is used to provide lateral movement thrust for the adjacent force-bearing rod 405;

[0040] The clamping unit includes a clamping block 402, a positioning rod 407, and a spring 408;

[0041] The clamping block 402 is fixed to the bottom end of the connecting rod 401, and the clamping block 402 is used to clamp both sides of the elevator profile;

[0042] The positioning rod 407 is fixed to the inner wall of the vertical sliding seat 3 and passes through the clamping block 402. The positioning rod 407 is used to provide a guide for the lateral movement of the clamping block 402;

[0043] Two ends of the spring 408 are respectively clamped on the inner wall of the vertical sliding seat 3 and the outer wall of the clamping block 402 . The spring 408 is used to provide elastic force for the clamping block 402 to reset.

[0044] In this embodiment: when using this device, by moving the axial sliding seat 1 along the guide rail to the top of the profile, the vertical sliding seat 3 and the cylinder 2 move with the movement of the axial sliding seat 1. When the vertical sliding seat 3 is close to the top of the elevator profile, the force-bearing rod 405 above the vertical sliding seat 3 will also gradually approach the block 406 fixed on the vertical rod, so that the inclined end of the block 406 contacts the end of the force-bearing rod 405 and gives the force-bearing rod 405 a lateral movement thrust. The laterally moving force-bearing rod 405 synchronously drives the rack 403 to move axially, and the moving rack 403 will synchronously push the connecting rod 401 to move. At the same time, the rack 403 gives the gear 404 a rotational thrust, so that the other rack 403 moves laterally synchronously. At this time, the two racks 403 move away from each other, so the connecting rod fixed to the rack 403 401 and the clamping block 402 fixed at the bottom end of the connecting rod 401 will also move away from each other. The moving clamping block 402 moves along the outer wall of the positioning rod 407 and gives squeezing force to the spring 408, so that when the clamping block 402 moves to the top of the profile, the distance between the clamping blocks 402 is greater than the width of the profile. At this time, the vertical sliding seat 3 can be pushed vertically by the cylinder 2, and the force-bearing rod 405 is always in contact with the inclined outer wall of the block 406 until the inner side of the clamping block 402 is on both sides of the profile. Then, when the axial sliding seat 1 moves axially again, the force-bearing rod 405 is no longer in contact with the block 406 and is reset under the elastic action of the spring 408. The reset clamping block 402 clamps both sides of the profile, completing the purpose of automatic clamping and lifting of the profile, further improving work efficiency and reducing costs.

[0045] Please refer to Figure 1-Figure 3The inner wall of the vertical sliding seat 3 is formed with a sliding groove for the axial movement of the clamping block 402. The outer wall of the clamping block 402 is an "L"-shaped structure as a whole. There are two racks 403, and the two racks 403 are staggered and symmetrically distributed at the top of the vertical sliding seat 3. The outer wall of the rack 403 is engaged with the outer wall of the gear 404. The moving trajectory of the force rod 405 coincides with the position of the block 406. There are two blocks 406, and the two blocks 406 are symmetrically distributed on the vertical pole connected to the ground. The end of the block 406 close to the force rod 405 is inclined.

[0046] In this embodiment: through this structure, after the lifting of the profile is completed, the moving axial sliding seat 1 and the vertical sliding seat 3 move the profile to the required position, and the force-bearing rod 405 above the vertical sliding seat 3 contacts the other block 406 again to drive the clamping blocks 402 away from each other, thereby releasing the clamping limit of the profile and completing the purpose of automatic disengagement of the profile.

[0047] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the scope of protection of the present invention.
