Abstract

The invention relates to the technical field of pumping unit braking, in particular to a beam-type pumping unit auxiliary brake device with a buffering function for an oil field. The beam-type pumping unit auxiliary brake device with the buffering function for the oil field increases buffering to realize reasonable locking and brake protection functions. The device comprises an auxiliary brake device, a brake device, a power assembly and the like; and the auxiliary brake device and the brake device are respectively connected with a brake shaft through keys, the power assembly is fixedly connected onto a mounting frame, and the power assembly is respectively connected with the auxiliary brake device and the brake device in a sliding manner. A pumping unit is braked through cooperation of the auxiliary brake device and the brake device, the auxiliary brake device and a buffer assembly in the brake device achieve stable braking, better locking, protection and alarm functions, the pumping unit is braked through an emergency brake device when an accident occurs, the dangerous situation caused by brake failure is avoided, and the power assembly controls the three devices in a linkage mode, and operation steps of workers are simplified.

Description

technical field [0001] The invention relates to the technical field of pumping unit braking, in particular to an auxiliary braking device for a beam pumping unit with a buffer function used in an oil field. Background technique [0002] In the process of oil extraction, the pumping unit is a very important mining equipment. Since oil extraction is mostly carried out in the wild and often faces various bad weather, ensuring the safety of the pumping unit is the key work of oil extraction. In various situations such as pumping unit overhaul, emergency stop of pumping operation, etc., the braking device of the pumping unit must be timely, accurate, reliable and safe. [0003] In the prior art, brake devices include two types of external embrace type and internal tension type, all of which utilize the friction pair to realize the braking of the pumping unit. With the increase of the service life, the normal wear and tear of the brake friction pair and the brake wheel The brakin...
