Description

Technical Field

[0001] The present application relates to the field of ground equipment in petroleum engineering, and in particular to a brake adjustment device. Background Art

[0002] The brake band gap needs to be adjusted every 2 to 3 times the workover rig is lifted and lowered at the workover operation site. Dust and oil often fall into the screw threads of the lead screw and turnbuckle connecting the brake band, which increases the torque during adjustment. The lead screw and turnbuckle are located low, and the commonly used standard wrenches have small rotation space and cannot fully engage the nut. They can only rotate about 20° each time. Multiple adjustments of the wrench angle are required to complete one circle of adjustment. Based on the current situation, the operator sometimes only adjusts the brake on one side, which will cause inconsistent brake angles on the left and right sides, or even serious deviations, resulting in reduced braking torque, lateral displacement of the brake band, and deformation of the brake hub and brake band taper.

[0003] With respect to the above-mentioned related technologies, the inventor believes that if the operator fails to adjust the brake properly, it will cause safety accidents and high labor intensity when drilling quickly. Utility Model Content
