Steel pipe water pressure detection device with automatic steel pipe clamping function

Abstract

The invention relates to a steel pipe water pressure detection device with an automatic steel pipe clamping function, belonging to the technical field of a steel pipe water pressure testing machine. The steel pipe water pressure detection device comprises a stander, wherein the stander comprises a left front stand column, a left rear stand column, a right front stand column, a right rear stand column, a front supporting beam, a rear supporting beam, a fixed bracket, a slide adjusting frame, a left beam frame and a right beam frame. The steel pipe water pressure detection device is characterized by also comprising an automatic steel pipe left clamping mechanism, a steel pipe water injection mechanism, an automatic steel pipe right clamping mechanism and a steel pipe end opening sealing mechanism, the automatic steel pipe left clamping mechanism and the steel pipe water injection mechanism are arranged on the left end of the stander, and the steel pipe water injection mechanism is arranged on the left side of the automatic steel pipe clamping mechanism; the automatic steel pipe right clamping mechanism and the steel pipe end opening sealing mechanism are arranged on the right end of the stander, the position of the automatic steel pipe right clamping mechanism corresponds to the automatic steel pipe left clamping mechanism, the position of the steel pipe end opening sealing mechanism corresponds to the steel pipe water injection mechanism, and the steel pipe end opening sealing mechanism is arranged on the right side of the automatic steel pipe right clamping mechanism. By adopting the steel pipe water pressure detection device with the automatic steel pipe clamping function, the operating intensity of online detection personnel can be alleviated, and the safety can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of steel pipe hydraulic test machinery, and in particular relates to a steel pipe hydraulic pressure detection device with the function of automatic clamping of steel pipes. Background technique [0002] The steel pipes mentioned above mainly refer to seamless steel pipes (hereinafter the same), and seamless steel pipes include hot-rolled seamless steel pipes and cold-rolled and cold-drawn seamless steel pipes. Because the seamless steel pipe has a hollow cross-section, it is widely used as a pipe for transporting fluids, such as transporting oil, natural gas, gas, water, and so on. Seamless steel pipes are widely used in the field of military industry, industry and even construction. As far as the field of military industry is concerned, it is used for satellites, aircraft, ships, etc. Power generation facilities, as far as the construction field is concerned, are mostly used as scaffolding.

Problems solved by technology

[0004] In the published Chinese patent literature, it can be seen that there are various technical information about the steel pipe water pressure detection device. The typical example is the authorized announcement number CN202770609U recommending a "steel pipe water pressure test machine". The quality is well known and well grasped, and can reflect the technical effect known in paragraph 0012 of the manual, but for each steel pipe to be tested, the handle and clamp must be manually operated by on-line testing personnel (see the Paragraph 0037 of the patent specification), in order to realize the clamping of the steel pipe before the test and the release after the test is completed, so not only the efficiency is low, but also the operation intensity of the online testing personnel is high

The "steel pipe hydrostatic test device" provided by CN203643110U is to arrange a fixed head and a movable head on the fixed frame, place the steel pipe to be detected between the fixed head and the movable head, and the movable head is displaced by the cylinder, Therefore, the steel pipe is clamped between the fixed head and the movable head. Compared with CN202770609U, this patented solution has the advantage of not relying on manual operations to clamp the steel pipe. However, because the steel pipe is relatively lengthy, in the actual detection process Risk of deflection causing the end of the tube to break free from the movable and / or fixed head

The "non-metallic pipeline water pressure leakage detection device" disclosed in the publication number CN102426084A belongs to the category of detection devices for municipal facility pipelines, and has no technical inspiration for reference for the detection of metal steel pipes
