The invention belongs to the field of oil drilling and workover, and provides a jaw plate frame braking and opening aligning mechanism for an iron roughneck. The mechanism comprises an upper jaw plateframe; an auxiliary jaw plate frame is connected onto the upper end surface of the upper jaw plate frame; a floating body and a lower jaw plate frame are arranged below the upper jaw plate frame; theouter side of the auxiliary jaw plate frame is sleeved with a braking disk; a first circular friction piece is fixedly arranged on the upper end surface of the upper jaw plate frame; inner cylinder mechanisms and a circular friction pressure piece are arranged in the braking disk; a circular limiting plate is arranged at the upper end of the outer side surface of the auxiliary jaw plate frame; asecond circular friction piece is arranged on the lower end surface of the circular limiting plate; a third circular friction piece is arranged on the upper end surface of the braking disk; positioning clamping blocks are arranged on the outer side surface of the braking disk; and positioning mechanisms matched with the positioning clamping blocks are arranged on the upper end surface of the floating body. According to the jaw plate frame braking and opening aligning mechanism for the iron roughneck, the braking structure is improved, a braking band is replaced by a braking pad, the mechanismis not prone to wear and long in service life, an opening aligning positioning mechanism is added, the opening aligning operation time is shortened, and the opening aligning 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...
