Technical Field

[0002] The vertical shaft sheave is a kind of equipment, which is usually used for wellhead operations such as oil wells, natural gas wells, and mines. It is mainly composed of a well wheel and a corresponding wheel frame. The main function of the vertical shaft sheave is to transmit power and bear the suspension of tools. When it is necessary to lift or lower the wellhead tools, the power is transmitted to the vertical shaft sheave through the winch or other lifting devices above, and the movement of the tool is achieved through the rotation of the well wheel, which makes it convenient to perform wellhead operations such as drilling, completion and well repair. However, the sheave rope liner replacement device is a device used to replace the drilling rope or working rope bushing on the vertical shaft sheave.

Each replacement requires multiple people to swing the sledgehammer to cooperate, the replacement efficiency is low, the time consumption is long, and the operation risk is high. Therefore, we proposed a sheave rope lining replacement device to solve the above problems. Utility Model Content
