Description

Technical Field

[0001] The utility model belongs to the technical field of pipe detection, and in particular relates to a PE drainage pipe tension resistance detection device. Background Art

[0002] Plastic pipes are mainly polyvinyl chloride pipes, polyethylene pipes, etc. Polyethylene pipes are also called PE pipes. Since PE pipes are mainly used for water supply and drainage, the most important data for pipes is the change in tension when the pipes are subjected to different water pressures, in order to monitor the maximum tension that the water pipes can withstand. The tension of the water pipes mainly comes from the water pressure inside the water pipes.

[0003] A search revealed a Chinese utility model patent with the publication number CN216560034U, which discloses a PE drainage pipe tension test device. The device comprises a fixing mechanism, a mounting and locking mechanism, a mobile monitoring mechanism, and the pipe to be tested. The fixing mechanism includes a mounting base, a fixed mounting plate disposed on one side of the top of the mounting base, a chute formed on the top surface of the mounting base, and symmetrically disposed movable tracks, two of which are positioned on either side of the chute and have an I-shaped cross-section. The mounting and locking mechanism includes a movable mounting plate and a water outlet pipe, the movable mounting plate being slidably mounted on the surfaces of the two movable tracks, and a slider disposed at the bottom of the movable mounting plate. This solution allows the internal mechanism to accurately observe the deformation of each region of the pipe when it is subjected to internal tension, thereby inferring changes in the pipe's internal tension.

[0004] However, after research, the applicant found that the above technical solution still has some technical problems when used. For example, when testing the same cross-section of the pipe, it is necessary to manually rotate the outside diameter micrometer, which is labor-intensive and inefficient. In addition, during the test, in order to ensure the stability of the outside diameter micrometer, it is also necessary to manually support the outside diameter micrometer to ensure its stability, which makes the operation even more inconvenient.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies.

[0006] Therefore, in order to solve the above problems, the utility model provides a PE drainage pipe tension resistance detection device. Utility Model Content

The rotation of the rotating ring can drive the outside diameter micrometer to rotate, so that the same cross-section of the pipe to be tested can be comprehensively tested.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0012] Furthermore, the placement frame is fixedly installed on the top end of the sliding block, the movable clamping plate is connected with a screw, and the screw is threadedly connected to the placement frame.

[0013] Furthermore, one end of the pipe to be tested is equipped with a plug, and the end is fixed by a group of the clamping mechanisms, the other end of the pipe to be tested is equipped with a connector, and the end is fixed by another group of the clamping mechanisms, one end of the connector is connected to the water injection pipe, and the pressure gauge is also installed on the connector.

[0016] Furthermore, the base plate is mounted on the electric guide rail.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the utility model, two sets of clamping mechanisms are used to fix the two ends of the pipe to be tested, and the spacing between the two sets of clamping mechanisms is adjustable, so that pipes of different lengths can be fixed. Then, by pulling the inner rod, the measuring needle on the outside diameter micrometer contacts the surface of the pipe to be tested, and then the fastening bolt is rotated so that one end of the fastening bolt contacts the inner rod, thereby limiting and fixing the inner rod. Then, clean water is injected into the pipe to be tested through the water injection pipe. The pressure in the pipe to be tested can be detected by the pressure gauge. By observing the value of the outside diameter micrometer surface, the deformation of the pipe to be tested due to the change in internal water can be inferred, thereby further measuring the deformation of the pipe to be tested under different internal pressures.

[0031] The first position adjustment mechanism 2 further includes a first motor 204 fixedly mounted at one end of the machine platform 1 , and an output end of the first motor 204 is connected to one end of the bidirectional lead screw 202 .

[0036] The base plate 703 is assembled on the electric guide rail 10 .

[0037] The working principle of the PE drainage pipe tension resistance detection device of the utility model is as follows: a plug is installed on one end of the pipe to be tested 4 and a connector is installed on the other end, the connection between the plug and the pipe to be tested 4 is placed on one of the placement frames 301, and then the screw 303 is rotated to drive the movable splint 302 to descend, so that the movable splint 302 can be pressed on the connection between the plug and the pipe to be tested 4, thereby fixing the end, and then the connection between the connector and the pipe to be tested 4 is placed on the other group of placement frames 301, and then the screw 303 is rotated to drive the movable splint 302 to descend, so that the movable splint 302 can be pressed on the connection between the connector and the pipe to be tested 4, thereby fixing the end, and then the first motor 204 is started, and the first motor 204 drives the bidirectional screw rod 202 to rotate, and the rotation of the bidirectional screw rod 202 drives the two sets of sliders 203 to move away from each other, and then drives the two sets of clamping mechanisms 3 to move away from each other, so that the pipe to be tested 4 is in a straight state, and then by pulling the inner rod 8 01, so that the measuring needle on the outside diameter micrometer 9 contacts the surface of the pipe to be tested 4, and then the fastening bolt 802 is rotated so that one end of the fastening bolt 802 contacts the inner rod 801, thereby limiting and fixing the inner rod 801. Then, clean water is injected into the pipe to be tested 4 through the water injection pipe 5. The pressure in the pipe to be tested 4 can be detected by the pressure gauge 6. By observing the value of the outside diameter micrometer surface 9, it is inferred that the pipe to be tested 4 has been deformed due to the change in internal water, thereby further measuring the deformation of the pipe to be tested 4 under different internal pressures. At this time, the second motor 705 drives the gear 706 to rotate, and the gear 706 drives the rotating ring 702 to rotate. The rotation of the rotating ring 702 can drive the outside diameter micrometer 9 to rotate, so that the same cross-section of the pipe to be tested 4 can be fully inspected. The outside diameter micrometer 9 can be driven by the electric guide rail 10 to move along the direction of the pipe to be tested 4, thereby achieving a comprehensive inspection operation of the pipe to be tested 4.
