Problems solved by technology

[0002] In recent years, some problems and potential safety hazards have been exposed in the maintenance of pumping units in oilfields
Oilfield pumping units need to replace and maintain the engine drive belt at regular intervals, and its maintenance operation method has always been a relatively backward manual replacement method
In the traditional method, whether adjusting the top wire or adjusting the slide rail, the ultimate goal is to reduce the center distance between the two pulleys by moving the motor. The adjustable range of this method is limited, generally within 50mm. Still need manual belt to remove and install the belt, still poses a safety hazard

Abstract

The invention discloses a motor belt rapid replacement device for a pumping unit in an oil field, and belongs to the field of petroleum machinery. The motor belt rapid replacement device comprises a driving device, a fixing device and an adjustment device. The driving device comprises a positioning shaft, a spline shaft and a first bearing. The fixing device comprises a non-standard spline sliding rail pair inner ring and a belt wheel shaft clamp. The adjustment device comprises a non-standard spline sliding rail pair outer ring, a second bearing, a lead screw, two lead screw seats, a screw nut, a revolving shaft seat, a third bearing and an outer ring bearing chamber. The non-standard spline sliding rail pair outer ring axially slides on the non-standard spline sliding rail pair inner ring so that a belt can break away from a belt wheel, and installation and detachment of the belt can be realized. The motor belt rapid replacement device can be installed on the belt wheel only through one bolt, so that operation is simple. A motor does not need to move when the belt is detached and installed, and contact between the hands and the belt can be completely avoided. By properly tensioning the belt, the replacement motion of the belt is finally realized without damaging the belt, safety risks are reduced, and operation efficiency is improved.

Description

technical field [0001] The invention relates to a quick replacement device for a motor belt of an oil field pumping unit, which belongs to the field of petroleum machinery. Background technique [0002] In recent years, some problems and potential safety hazards have been exposed in the maintenance of pumping units in oilfields. Oilfield pumping units need to replace and maintain the engine drive belt at regular intervals, and its maintenance operation method has always been a relatively backward manual replacement method. In the traditional method, whether adjusting the top wire or adjusting the slide rail, the ultimate goal is to reduce the center distance between the two pulleys by moving the motor. The adjustable range of this method is limited, generally within 50mm. Still need manpower belt to disassemble and install belt, still have potential safety hazard. [0003] In order to reduce the labor intensity of front-line oil production workers, improve the working time...
