Abstract

The invention belongs to the field of oil drilling and workover, and provides a jaw frame braking and opening alignment mechanism for iron drillers, including a jaw plate rack, a jaw plate sub-frame connected to the upper end of the jaw plate rack, and a jaw plate sub-frame below. The floating body and the lower frame of the jaw plate are equipped with a brake disc on the outer side of the jaw plate sub-frame; the upper end surface of the jaw plate is fixed with a first friction ring, and the brake disc is equipped with an inner cylinder mechanism and a friction pressure ring; the jaw The upper end of the outer surface of the plate sub-frame is provided with a limit ring plate, the lower end surface of the limit ring plate is provided with a second friction ring plate, the upper end surface of the brake disc is provided with a third friction ring plate; the outer surface of the brake disc is provided with a positioning block, The upper end surface of the floating body is provided with a positioning mechanism matched with the positioning block. The invention is a jaw frame brake and opening alignment mechanism for iron drillers, which improves the braking structure and uses brake pads instead of brake bands, which is not easy to wear and has a long service life. The opening alignment and positioning mechanism is added to shorten the opening The alignment operation time is shortened, and the opening alignment efficiency is improved.

Description

technical field [0001] The present invention relates to a mechanical device, and more particularly to a jaw frame brake and opening alignment mechanism for iron drillers. Background technique [0002] At present, the brake device of the iron driller uses a brake band for the brake part. After a period of use, the brake point will wear out, not only the braking effect will be reduced, but also there will be hidden dangers of breakage, and the service life will be short. In addition, current iron drillers need to manually participate in changing the reversing pin when reversing to the gap, which is time-consuming and laborious, and the efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome the existing defects, provide a jaw plate frame brake and opening alignment mechanism for iron drillers, and solve the problem of short life of the brake components of the current iron driller braking device and poor opening alignment oper...
