AI Technical Summary

Technical Problem

In the prior art, when disassembling the oil pipe thread, the labor amount is large and the operating accuracy is limited, resulting in low disassembly efficiency and prone to problems such as wire jamming.

Method used

A tubular thread removal device is designed, including a rotating assembly, a connecting rod assembly and a tightening block. The connecting rod assembly of the screw is driven by the rotational drive of the screw, and the fastening block is moved in the radial direction of the screw, and the inner wall of the oil pipe thread is pressed, thereby achieving disassembly.

Benefits of technology

The device automatically disassembles the oil pipe thread through the rotation of the screw, ensuring the balance of the force and the accuracy of the force direction, improving the disassembly efficiency and reducing the amount of manual labor.

Abstract

The utility model provides an oil pipe screw thread dismounting device. The oil pipe screw thread dismounting device comprises a rotating assembly, a connecting rod assembly and an abutting block. The rotating assembly comprises a screw rod, a first support matched with the screw rod through a bearing and a second support matched with the screw rod through threads. Each connecting rod assembly comprises a first connecting rod and a second connecting rod, one ends of the first connecting rod and the second connecting rod are hinged to the first support and the second support respectively, and the other ends of the first connecting rod and the second connecting rod are hinged to each other; the abutting block is arranged at the hinged point of the first connecting rod and the second connecting rod of each connecting rod assembly. The second support can move in the axial direction of the screw rod when the screw rod rotates and drive the abutting block to abut against the inner wall of the oil pipe screw thread through the connecting rod assembly. Based on the technical scheme, the abutting blocks can abut against the inner wall of the oil pipe screw thread from different positions in the circumferential direction, the stress balance of all the positions and the accuracy of the stress direction are guaranteed, and then the oil pipe screw thread can be automatically disassembled through rotation of the screw rod.
