AI Technical Summary

Technical Problem

It is difficult for the prior art to effectively correct the screw of the screw opening and closing machine without disassembling the screw, and the existing correction methods have the risk of destroying the thread and deformation of the clamping part.

Method used

A device including mounting bracket, correction frame and hydraulic cylinder is designed. By setting a surround frame and correction frame outside the screw, the hydraulic cylinder pushing and bonding frame is used to roll and correct the rolling and pressing correction to avoid clamping and pressing fulcrum points.

Benefits of technology

The screw opening and closing machine is accurate in situ correction, avoiding thread damage and support position deformation, and improving the efficiency of correction and maintenance.

Abstract

The invention relates to the technical field of screw hoist maintenance, in particular to an in-situ precise measurement and control correction device for a screw of a screw hoist, the in-situ precise measurement and control correction device comprises a mounting bracket and two groups of correction frames, an electric cylinder is mounted on the inner side of the mounting bracket, the telescopic end of the electric cylinder is fixedly connected with a suspension, and the right side of the suspension is fixedly connected with a surrounding frame. The in-situ precise measurement and control correction device for the screw of the screw hoist is provided with an undeformed part which can be in contact with the screw after the correction rollers get close to each other, and at the moment, the circle center of an approximately-annular support composed of the two correction frames is concentric with the axis of the screw; when pushing force is applied to the two attaching frames at the diagonal positions, the attaching frames and the correcting rollers connected with the attaching frames can rotate circumferentially along the axes and make contact with the protruding parts of the screws at the moment, when the attaching frames are repeatedly pushed and pressed, the correcting rollers can roll and press the protruding parts of the attaching frames till the protruding parts are concentric with the axes, and the rolling and correcting effects are achieved.
