Water pressure testing machine tube length infinitely adaptable to the rotary device

Abstract

The invention provides a water pressure testing machine pipe length infinitely adaptable rotary device, including a bearing frame, one end of which is processed with a mounting structure, a proximity switch is installed in the mounting structure, and a driving mechanism is installed on the bearing frame, and the driving mechanism drives The carrier moves back and forth along its own axis. This infinitely adaptable rotary device adopts the transmission method that the hydraulic motor drives the screw nut pair through the chain transmission to drive the moving sealing device to move, so that the huge axial water pressure in the pressure test process is finally borne by the screw nut, and its power is not enough for top bending. Steel pipe, and its rigidity and self-locking ensure that the mobile sealing device under high pressure will not retreat; avoiding the disadvantages of the main hydraulic cylinder's thrust being too large to bend the steel pipe, and the main hydraulic cylinder retreating to damage the sealing ring in the past pressure test process; The direction of tube length adopts spiral movement, which can adapt to the change of tube length steplessly.

Description

Technical field [0001] The present invention is the field of water pressure test equipment technology, involving a hydraulic test equipment, which specifically involves a tube long and unparalleled rotation device necessary for the pipe length and non -pole adverse adapter of the pipe resistance test for boiler steel pipes, petroleum oil well pipes, pipeline pipe pipes. Background technique [0002] With the growth of the industrial and agricultural production and service industry worldwide, the development of the transportation industry, and the improvement of people's living standards, the market demand for energy such as oil and natural gas such as oil and natural gas has expanded.In recent years, oil exploration and development, especially natural gas development, has continued to expand the demand for oil pipes and pipes.According to the requirements of the SY / T 6194 "sleeve and oil pipe", oil oil use of oil, the suite factory, and before using the static water pressure test...

AI Technical Summary

Problems solved by technology

The large-stroke movement of the traditional sealing device is mainly satisfied by the large-stroke hydraulic cylinder, which is high in cost and slow in speed. At the same time, if the thrust of the main hydraulic cylinder is too large during the pressure test, the steel pipe will be bent, and the thrust of the small main hydraulic cylinder will damage the sealing ring.
