Automatic hydraulic testing jig

Abstract

The invention discloses an automatic hydraulic testing jig which comprises a hydraulic cylinder 1, a hydraulic cylinder base 2, a movable head measuring frame 3, a truss 4, a fixed head measuring frame 5, a drag chain 6 and a control console 7, wherein the movable head measuring frame 3 is connected with the hydraulic cylinder 1 at the front end of the truss 4; and the hydraulic cylinder 1 and the fixed head measuring frame 5 are respectively connected with the control console 7 through an electrical and hydraulic operation system. The test range of the load, the diameter and the length is enlarged; the hydraulic cylinder is used for providing a load applied for the test; the speed of a piston rod can be adjusted; the measured impact force is reduced; the fixed head measuring frame 5 realizes self-traveling and hydraulic inserting and positioning at the truss 4 through a rack and pinion; the test device is controlled by adopting two sets of methods, namely hydraulic and manual and automatic control; and data are acquired, displayed, recorded and printed by configuring a computer-assisted test system; and a panel of the control console 7 is used for displaying a curve graph of the load amplitude, the time, the load and the displacement, thus the measuring efficiency is improved.

Description

technical field [0001] The invention relates to a hydraulic test stand, in particular to an automatic hydraulic test stand, which belongs to the field of test and measurement equipment for downhole petroleum tools. Background technique [0002] Downhole oil tools such as oil drilling tools, jarring tools, fishing tools, accelerators and shock absorbers must be tested for their tensile and pressure properties before going into the well and during maintenance. It is usually necessary to put these tested petroleum tools on a hydraulic test stand for testing. At present, the automatic performance of the hydraulic test stand used for testing petroleum tools is poor, and the manual labor intensity is high. Because of the high hydraulic pressure test, the safety precaution level is low, and the test load is small, so it cannot test high-load petroleum tools. Contents of the invention [0003] The purpose of the present invention is to provide an automatic hydraulic test stand to...
