Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, and more particularly to a basalt fiber composite pipe pressure testing device. Background Art

[0002] Basalt fiber composite pipes are widely used in petrochemicals, municipal water supply and drainage, marine engineering and other fields due to their high strength, corrosion resistance and light weight. Their pressure-bearing performance is a key indicator that determines their safety and service life. However, traditional pressure testing methods have many limitations. Early tests mostly used simple manually operated equipment, manually applying pressure and observing the pressure gauge readings with the naked eye. This was not only inefficient and had large errors, but also difficult to simulate the dynamic pressure changes of composite pipes under complex working conditions, and easily missed problems such as tiny cracks or insufficient local strength.

[0003] The traditional test device has a simple way of fixing the composite pipe, which is prone to loosening due to differences in pipe length and diameter, causing the pipe to shift or fall off during pressurization. It cannot flexibly adapt to basalt fiber composite pipes of different specifications. When replacing the test pipe, the clamping and sealing structure must be readjusted, which is cumbersome and prolongs the test preparation time. After long-term use of the equipment, the friction between the bidirectional screw and the moving block intensifies. Manual lubrication requires frequent shutdowns and uneven distribution of lubricating oil, which leads to accelerated wear of components and shortened equipment service life. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the existing technology, the utility model provides a basalt fiber composite pipe pressure testing device, which has the following beneficial effects:

[0017] 1. Multi-angle clamping and fixing: The clamping motor drives the clamping screw to rotate, so that the clamping block pushes the clamping rod through the inclined groove, driving the clamping frame to tighten from both sides toward the center of the pipe. With the guidance of the sliding block and the sliding groove, it can adapt to composite pipes of different diameters.

[0018] 2. The supporting motor drives the bidirectional screw to rotate, driving the moving blocks to move closer synchronously, so that the conical plug fits tightly against both ends of the pipe, achieving a sealed seal, avoiding leakage during pressurization, and ensuring the accuracy of the pressure test data.

[0019] 3. The cooperation of the control lever, control head and control spring can manually control the opening and closing of the lubrication groove. When lubrication is needed, pull up and turn the control lever to engage the movable plate with the baffle. The lubricating oil will continuously flow out from the lubrication cavity through the lubrication groove and evenly cover the surface of the bidirectional screw as the moving block moves. After lubrication is completed, reset the control lever to close the lubrication groove to avoid waste of lubricating oil. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, when in use, the middle of the pipe is supported by the clamping frame 2, and the clamping motor 19 is started. The clamping motor 19 drives the clamping screw 20 to rotate, driving the clamping plate 21 and the clamping block 14 to move upward, and the clamping block 14 drives the clamping frame 2 to clamp and move toward one side of the pipe through the cooperation of the inclined groove 16 and the clamping rod 15.

The slide 12 is in a continuously open state. Through the cooperation between the bidirectional screw 4 and the moving block 7, the lubricating oil moves with the moving block 7 and is spread on the bidirectional screw 4 to lubricate the bidirectional screw 4. When the lubrication maintenance is completed, the movable plate 26 and the baffle 27 are staggered. The control head 25 moves downward and resets under the elastic force of the control spring 28, so that the control head 25 is blocked in the control groove 22 to prevent the lubricating oil from continuing to flow out.
