Steel pipe water pressure detecting device

Abstract

The invention discloses a steel pipe water pressure detecting device and belongs to the technical field of steel pipe water pressure testing machines. The steel pipe water pressure detecting device comprises a rack, a left steel pipe clamping mechanism, a steel pipe water injecting mechanism, a right steel pipe clamping mechanism, a steel pipe opening sealing mechanism, a left steel pipe lifting mechanism, a right steel pipe lifting mechanism and a steel pipe dragging mechanism, wherein the left steel pipe clamping mechanism and the steel pipe water injecting mechanism are arranged at the left end of the rack; the right steel pipe clamping mechanism and the steel pipe opening sealing mechanism are arranged at the right end of the rack; the left steel pipe lifting mechanism is supported on a terrace and corresponds to the right side of the left steel pipe clamping mechanism, and the right steel pipe lifting mechanism is supported on the terrace and corresponds to the right side of the right steel pipe clamping mechanism; the steel pipe dragging mechanism is supported on the terrace and corresponds to the middle part of the rack. The steel pipe water pressure detecting device has high detection efficiency and allows a steel pipe manufacturer to carry out comprehensive detection on produced steel pipes, and the overstock of steel pipes to be detected can be avoided; the labor intensity of online detection workers is reduced, and the safety is ensured; the steel pipe manufacturer can conveniently control the quality of the produced steel pipes, and the phenomenon that unqualified defective steel pipes are mixed in qualified steel pipes is avoided.

Description

technical field [0001] The invention belongs to the technical field of steel pipe hydraulic testing machinery, and in particular relates to a steel pipe hydraulic testing device. 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. [0003] In order to ensure the quality of the steel pipe, in addition to t...

AI Technical Summary

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 of the product is well known and well grasped, and can reflect the technical effect known in paragraph 0012 of its manual, but there are the following deficiencies: First, because only one steel pipe can be tested at a time, it cannot meet the expectations of steel pipe manufacturers Because the production efficiency of steel pipes is generally high, if you test one by one (one by one), it will inevitably delay the timing of the product leaving the factory, and even the phenomenon of accumulation (backlog) of steel pipes to be tested will occur. However, if the test is carried out by random inspection, Then it is impossible to guarantee whether all the steel pipes of the same batch can reach the required quality indicators; the second is that the test operation of the workers needs to be tested manually by the online operators; The test is performed manually, so the quality of the test is difficult to guarantee, because the quality of the test has a certain relationship with the tester's experience, physical fitness, psychology, sense of responsibility and other factors

Undoubtedly, if the number of "steel pipe hydraulic testing machines" is increased, the first of the aforementioned three deficiencies can be eliminated, but increasing the number of "steel pipe hydraulic testing machines" will not only take up space and increase the cost of testing In addition, additional testers are required, resulting in a waste of valuable labor resources

Moreover, since the addition of "steel pipe hydraulic testing machine" cannot eliminate the aforementioned second and third deficiencies, it is purely a negative measure that treats the symptoms rather than the root cause and is a negative measure that takes into account one thing at the expense of another.
