Automatic counting alignment winch for offshore oil well high pressure oil pipe

Abstract

The invention discloses an automatic counting alignment winch for an offshore oil well high pressure oil pipe, which comprises a base. A motor support and a fixed shaft support are correspondingly arranged on the base; pipe line aligning device supports are also arranged on each side of the motor support and the fixed shaft support of the base; a motor is arranged at the top end of the motor support; a counter is fixed on the motor support; a fixed shaft is arranged at the top end of the fixed shaft support; a pipeline aligning device is arranged at the top end of each pipe line aligning device support; an output shaft of the motor is connected to one end of a central shaft hole of a thread spool; one end of the fixed shaft is connected to the other end of the central shaft hole of the thread spool; and a counter sensor is arranged on the pipeline aligning device and is connected with the counter through a wire. An automatic alignment function and an automatic pipe line length metering function of the underground high pressure oil pipe are realized by the automatic counting alignment winch for the offshore oil well high pressure oil pipe instead of the common winch; and the problem that the winch is always hoisted and transported because the platform work sites are not regular is solved, so that the positive and reverse installation of a cylinder can be realized, and the pipe line is freely wound and unwound.

Description

technical field [0001] The invention relates to a drawworks for high-pressure oil pipes of offshore oil wells. In particular, it relates to an automatic counting and straightening winch for offshore oil well high-pressure tubing with automatic straightening function Background technique [0002] Cable and tubing winding winches used in offshore mine operations are frequently used. Currently, the HY type winches used in conventional offshore platforms have the advantages of easy operation, but there are many problems and deficiencies. For example: [0003] 1. Offshore oil well measurement operations need to use automatic winches to automatically transport high-pressure oil pipes downhole, the maximum depth can reach several thousand meters, but because the material of high-pressure oil pipes is stainless steel, it is easy to cause bending deformation during transportation, and manual straightening is required in time. However, ordinary winches cannot achieve automatic strai...

Problems solved by technology

[0003] 1. Offshore oil well measurement operations need to use automatic winches to automatically transport high-pressure oil pipes downhole, the maximum depth can reach several thousand meters, but because the material of high-pressure oil pipes is stainless steel, it is easy to cause bending deformation during transportation, and manual straightening is required in time. Ordinary winches cannot achieve automatic straightening, and the work of straightening thousands of meters of pipelines brings a huge workload to workers

[0004] 2. It is impossible to measure the length of the high-pressure oil pipe on the ordinary winch. We can only estimate how many meters the line has been set out and the depth of the well, etc. through the experience of the workers. Therefore, it is necessary to realize the automatic counting function of the length of the pipeline on the winch. Operators Timely and convenient control of wire release
