Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bending, in particular to a bending structure of an elevator guide rail. Background Art
[0002] Elevator guide rails are two or more rows of vertical or inclined rigid rails installed in the elevator shaft or between floors to ensure that the car and counterweight move up and down along them, and that the steps of escalators and moving walkways move inclined or horizontally along them, providing guidance for the elevator car, counterweight device or steps.
[0003] The existing bending structure generally fixes the guide rail first, and then squeezes and bends the guide rail through the hydraulic telescopic structure. However, in actual use, due to the difference in lengths of different guide rails, it is necessary to adjust the positions of the clamping structure and the hydraulic telescopic structure to meet the bending needs. However, the existing clamping structure is generally a fixed position structure, so the size of the guide rail to be bent is also limited, resulting in a narrow application surface of the existing bending structure, which cannot meet the bending needs of different guide rails. Based on this, the utility model designs an elevator guide rail bending structure to solve the above problems. Utility Model Content

[0032] In the embodiment of the utility model, since the lengths of the parts may be different, the servo motor 3 is started at this time. The start of the servo motor 3 can drive the one-way screw 4 to rotate. Since the moving block 6 is threadedly connected to the outer ring of the one-way screw 4, the moving block 6 will move with the rotation of the one-way screw 4. Since the clamping block 12 is arranged on the top of the moving block 6, starting the servo motor 3 can drive the clamping block 12 to move.
[0033] Embodiment 2:
