Abstract

The invention relates to a testing device for a supporting mechanism of a drilling traction robot. It mainly consists of support baffle, tension and pressure sensor A, tension and pressure sensor B, tension and pressure sensor C, tension and pressure sensor D, hydraulic pressure A, hydraulic pressure B, hydraulic pressure C, hydraulic pressure D, displacement sensor A, displacement sensor B, simulated shaft, support It is composed of tie rod, bottom plate, telescopic pull rod, telescopic baffle, axial thrust bearing, support / torque baffle, slider A, slider B, support block A, support block B, connecting rod support mechanism, and wedge support mechanism. The purpose of the present invention is to provide a testing device for the support mechanism of a drilling traction robot, measure key parameters such as the support force, traction force, and torque of the support mechanism of the drilling traction robot, shorten the research and development cycle of the drilling traction robot, reduce the experimental cost of the drilling traction robot, and provide support for the optimal design of the support mechanism structure. The experimental data is used as a reference to promote the theoretical research and engineering popularization and application of drilling traction robots.

Description

technical field [0001] The invention relates to the field of downhole robots, in particular to a testing device for a supporting mechanism of a drilling traction robot. Background technique [0002] With the rapid development of my country's national economy and the improvement of people's living standards, my country's demand for energy has grown rapidly, and the contradiction between energy supply and demand has become increasingly prominent. The degree of dependence on foreign oil and natural gas has increased year by year. Climb to 45.3%, greatly exceeding the internationally recognized warning line, a serious threat to my country's energy security. With the deepening of exploration and development, low-permeability, low-porosity and other tight oil and gas (such as shale gas, etc.) have gradually become the focus of exploration and development. For example: According to the report of the United Nations Conference on Trade and Development in 2018, my country's shale gas ...

Problems solved by technology

In terms of the drilling traction robot experimental system, two patents have been invented: CN201710705983.2 and CN201710720406.0, but these two patents can only carry out the traction force, traction speed and control experiments of the drilling traction robot, and cannot test the support of the supporting mechanism force, traction, and torque parameters, the reliability evaluation experiment of the support mechanism of the drilling traction robot cannot be carried out, and the anti-blocking characteristic experiment cannot be carried out

[0007] Therefore, because the existing downhole robot-related experimental devices are mainly complete machine experimental devices, the structure of the experimental device is extremely complicated, and the overall prototype of the drilling traction robot needs to be processed to carry out the experiment, resulting in a long test preparation period and high test costs, and it is impossible to provide a support mechanism. The structural optimization design provides experimental data reference, which to some extent restricts the theoretical research and engineering application of drilling traction robots
