Description

Technical Field

[0001] The utility model relates to a detachable slide rail driving device, in particular to a detachable slide rail driving device for an oil pumping unit motor. Background Art

[0002] At present, most of the domestic oil fields still use Yuliang oil pumping units. The wear of the belt will cause the pumping unit to be shut down for maintenance, affecting the efficiency of oil extraction.

[0003] In the process of oilfield production management, the belt of each pumping unit needs to be replaced 2 to 3 times a year on average. Each replacement takes half an hour and requires two maintenance personnel to work together. At the same time, during the belt replacement process, maintenance personnel are also required to master various safety knowledge to avoid personal safety problems during the belt replacement process. There are two reasons for the difficulty in belt replacement. The first is the difficulty in moving the working motor platform due to its heavy weight; the second is that the tightness of the belt needs to be manually checked by personnel, and when the belt tightness is not appropriate, it needs to be adjusted many times. The difficulty in replacing the pumping unit belt will lead to reduced oil extraction efficiency, and there will be irregular operations by maintenance personnel. Based on these problems, technical means need to be used to optimize the design of the pumping unit platform. Use a small motor as a power source to push the slide rail to make the pulley move back and forth. Without changing the operating process of belt replacement, the speed of belt relaxation and tightening and the appropriateness of belt tightness can be accelerated. Utility Model Content
