Abstract

The invention discloses a safety unloading device for a pumping unit load, which is characterized by comprising a top drive mechanism and a support mechanism; the support mechanism sits on the wellhead packing box of the pumping unit; the top drive mechanism is connected to the on the support mechanism; the support mechanism is used to support the top drive mechanism so that the top drive mechanism stands directly below the polished rod clamp of the pumping unit; the top drive mechanism is used to support the polished rod clamp of the pumping unit Apply a straight upward force; the force is used to unload the pumping unit load; to solve the problem that the existing pumping unit load unloading needs to assist the use of large equipment such as cranes, so that the controllability, safety and unloading efficiency of the unloading operation are low And other issues.

Description

technical field [0001] The invention relates to an auxiliary tool for maintenance and repair of an oil pumping unit, in particular to a safety unloading device for an oil pumping unit. Background technique [0002] It can be carried out on the premise that the load of the pumping unit needs to be unloaded when the pumping unit needs to replace the braid or adjust the stroke. In traditional unloading operations, it is necessary to use impact unloading with the assistance of a large crane. The impact force at the moment of impact is large, which leads to the phenomenon that the square clip damages the sucker rod. After the damage, the sucker rod can be repaired and needs to be repaired. For this reason, the controllability and unloading efficiency during the unloading operation are low, the unloading cost is high, and even certain safety accidents may occur. SUMMARY OF THE INVENTION [0003] In view of this, the present invention provides a safety unloading device for pumpi...
