AI Technical Summary

Problems solved by technology

During the operation of the machine, due to the load of the pumping unit or the quality of the steel wire rope or the quality of the polished rod, sometimes the polished rod breaks off or the braids break off or the polished rod clip slips off, causing the balance mechanism to fall freely without control of the balance box of more than ten tons. The base of the pumping unit was smashed, and the pumping unit was forced to stop production to replace it, which increased production and maintenance costs and directly affected the completion of crude oil production

Abstract

The present invention relates to a vertical oil-pumping unit balancing mechanism quick brake equipment. It is mainly composed of the following several portions: connecting plate, balancing plate, equalizing beam, connecting rod, grabbing frame, guide block, brake steel wire rope, slide wedge, balancing tank, spring seat, supporting plate, seat plate, pull-rod, pin shaft, spring, connecting bolt and nut. Said invention also provides the connection mode of all the above-mentioned portions, and provides the working principle of said quick brake equipment and its concrete operation method.

Description

1. Technical field [0001] The invention relates to a speed brake device for the balance mechanism of a vertical oil pumping unit, which prevents the polished rod or the braid from breaking off, causing the balance mechanism to fall uncontrollably. 2. Background technology [0002] Vertical pumping unit refers to the electric drum pumping unit newly developed by scientific and technological personnel in recent years. The electric drum is the driving equipment of the pumping unit. It is set on the platform at the top of the vertical frame. The steel wire rope set on the drum pulls the polished rod to reciprocate vertically up and down to pump oil. It is balanced by the balance mechanism, which is different from the chain pumping unit. During the operation of the machine, due to the load of the pumping unit or the quality of the steel wire rope or the quality of the polished rod, sometimes the polished rod breaks off or the braids break off or the polished rod clip slips off, c...
