As shown in fig. 5 to 6, the top surface of the top plate 26 is disposed in an arc shape; the top of the top plate 26 is smooth; when the hollow elevator guide rail moves on the top surface of the top plate 26, the top surface of the top plate 26 is in an arc-shaped and smooth arrangement, so that friction between the hollow elevator guide rail and the top plate 26 can be reduced, and abrasion of the hollow elevator guide rail is reduced.
When the elevator guide rail straightening device is used, when the elevator guide rail needs to be straightened, a user needs to fix the elevator guide rail between the two support plates 1 through the clamping assembly, then the user adjusts the laser level 5, and enables the laser emitted by the laser level 5 on the top surface and the bottom surface of the support plates 1 to just pass through the top surface and the bottom surface of the elevator guide rail and irradiate the laser receiving plate 6 on the surface of the support plate 1 on the other side, if the surface of the elevator guide rail is bent, the elevator guide rail is caused to shield part of the laser emitted by the laser level 5, the laser receiving plate 6 cannot receive the laser emitted by the laser level 5, at the moment, the external motor on the corresponding side drives the electric telescopic rod 2 to move to the laser shielding position, then the electric telescopic rod 2 drives the connecting plate 3 and the hydraulic cylinder 4 to be close to the protruding position of the bending part of the elevator guide rail, and the telescopic end of the hydraulic cylinder 4 extrudes the protruding position of the elevator guide rail for a plurality of times, and enables the elevator guide rail to be bent reversely in the extrusion process, so that the internal stress of the elevator guide rail is eliminated, and the elevator guide rail is prevented from rebounding after the elevator guide rail is straightened.
For the convenience of customers fixed elevator guide rail, the servo motor 8 at the both ends of backup pad 1 can be started simultaneously to the user, drives double-tooth screw rod 7 through servo motor 8 and rotates for two backup pads 1 keep away from each other, and will lengthen board 10 and draw to the direction of keeping away from spout 9 tank bottom, thereby enlarge the clearance between two backup pads 1, and then the convenience of customers puts into elevator guide rail between two backup pads 1, in order to facilitate the use to fix elevator guide rail.
