Technical Field

[0001] The utility model relates to the technical field of pressure resistance detection devices, in particular to a steel pipe pressure resistance detection device. Background Art

[0002] A steel pipe is a long strip of steel with a hollow cross-section and no seams around it. To ensure the quality of the steel pipe, it is necessary to conduct a pressure test on the steel pipe before it is put into normal use. This is to ensure the service life of the seamless steel pipe and prevent the seamless steel pipe from malfunctioning and injuring staff during use. The steel pipe pressure test often uses the airtight method to test the steel pipe's pressure resistance, which requires sealing both ends of the steel pipe and injecting gas.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: when using the traditional device, it is necessary to first fix the flange on the steel pipe and then fix the airtight device on the flange. However, this method will cause the steel pipe inspection to take a long time, thereby reducing the inspection efficiency of the device. Utility Model Content

[0007] By adopting the above technical solution, the first end plate and the second end plate are located at the two ends of the steel pipe. The staff drives the first end plate and the second end plate to move toward the direction of the steel pipe until the sealing plug contacts the end of the steel pipe and clamps the steel pipe through the clamping piece, so that the first end plate and the second end plate can be quickly installed on the two ends of the steel pipe. Then the air pump injects gas into the steel pipe through the air guide pipe to perform pressure resistance test on the steel pipe, thereby achieving the purpose of quickly sealing the steel pipe by the device and improving the detection efficiency of the device.

[0010] Optionally, an anti-slip groove is provided at one end of the clamp away from the telescopic end of the electric hydraulic telescopic rod.

[0011] By adopting the above technical solution and setting the anti-slip groove, the friction between the chuck and the steel pipe is increased, and sliding between the steel pipe and the chuck during the clamping process is avoided as much as possible.

[0012] Optionally, five clamping members are provided on the first end plate and the second end plate, and the support ring, the clamp head, the electric hydraulic telescopic rod and the anti-slip groove correspond to each other one by one.

[0013] By adopting the above technical solution, the steel pipe is clamped simultaneously by multiple clamping members, so that the steel pipe is clamped more firmly, thereby improving the stability of the device during the detection process.

[0014] Optionally, the limiting member includes a plurality of limiting rods, which are installed on opposite surfaces of the first end plate and the second end plate, and a plurality of limiting holes are provided on the surface of the sealing plug away from one end of the steel pipe, and the plurality of limiting rods are installed one by one inside the plurality of limiting holes.

[0015] By adopting the above technical solution, the stability of the sealing plug installed on the surfaces of the first end plate and the second end plate is increased.

[0016] Optionally, the sealing plug is a half-spherical structure.

[0017] By adopting the above technical solution, it is convenient to seal the end of the steel pipe through the sealing plug.

[0018] In summary, the present invention has at least one of the following beneficial effects:

[0019] Through the coordinated arrangement of the clamping member, the first end plate, the second end plate, the air pump, the air duct, the sealing plug and the support column, the clamping member facilitates the rapid installation of the first end plate and the second end plate on both ends of the steel pipe, and enables the sealing plug to seal the ends of the steel pipe, making it convenient for the air pump to inject gas into the steel pipe through the air duct and perform pressure resistance testing on the steel pipe, thereby improving the detection efficiency of the device.

[0020] By inserting a plurality of limiting plug rods into the limiting plug holes, the first end plate and the left end sealing plug as well as the second end plate and the right end sealing plug can be limited, thereby increasing the stability of the sealing plugs installed on the surfaces of the first end plate and the second end plate.

When the electric hydraulic telescopic rod 13 is contracted, the chuck 12 rotates with it, so that the chuck 12 is away from one end of the electric hydraulic telescopic rod 13 to clamp the steel pipe, which is convenient for quickly installing the first end plate 2 and the second end plate 3 at both ends of the steel pipe.

[0031] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 and Figure 6 The end of the chuck 12 away from the telescopic end of the electric hydraulic telescopic rod 13 is provided with a plurality of anti-skid grooves 14. The anti-skid grooves 14 are provided to increase the friction between the chuck 12 and the steel pipe, and to avoid sliding between the steel pipe and the chuck 12 during the clamping process.

[0032] Please refer to the attached figure in the instruction manual Figure 1 , Figure 3 and Figure 4 There are five clamping members 1 on each of the first end plate 2 and the second end plate 3, and the support ring 11, the clamp head 12, the electric hydraulic telescopic rod 13 and the anti-slip groove 14 correspond to each other. The steel pipe is clamped more firmly by multiple clamping members 1 at the same time, thereby improving the stability of the device during the detection process.

[0033] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 and Figure 4 The air pump 4 is fixedly mounted on the outer surface of the first end plate 2, the air guide tube 5 is fixedly mounted on the inner surface of the first end plate 2, and the air guide tube 5 is installed at the air outlet of the air pump 4.

The sealing plug 6 is a half-spherical structure. It is convenient to seal the end of the steel pipe through the sealing plug 6.

[0034] Please refer to the attached figure in the instruction manual Figure 1 , Figure 5 and Figure 6A limiting member is provided between the first end plate 2 and the second end plate 3 and the sealing plug 6, and the limiting member includes a plurality of limiting plug rods 8, and the plurality of limiting plug rods 8 are fixedly installed on the opposite surfaces of the first end plate 2 and the second end plate 3.
