Description

Technical Field

[0001] This utility model relates to the field of pressure pipeline testing technology, and in particular to a pressure pipeline wall thickness testing device. Background Technology

[0002] During the production of pressure pipelines, their wall thickness needs to be tested. If the thickness does not meet the standard, the pipeline cannot be used. The wall thickness test requires a pressure pipeline wall thickness testing device.

[0003] A search revealed that patent document CN220853536U discloses a device for online detection of pressure pipeline wall thickness, belonging to the field of pipeline inspection technology. The device includes an operating platform with positioning rings fixedly installed at both ends. A detection ring is rotatably engaged within the positioning rings. Clamping structures are installed on both sides of the detection ring, and a rotating gear ring is installed at the other end. A sliding hole is provided inside the operating platform, and a transverse sliding structure is installed inside the sliding hole. An electric telescopic rod is embedded in one side of the transverse sliding structure. A wall thickness detector is embedded in the upper surface of one side of the operating platform. A transmission connection line is installed on one side of the wall thickness detector, and a thickness detection head is installed at the other end of the transmission connection line. The thickness detection head is fixedly installed at the output end of the electric telescopic rod. Using the detection ring, the pipeline can be rotated, improving the comprehensiveness of pipeline inspection. The transverse sliding structure drives the device to scan and inspect the middle section of the pipeline, improving the flexibility and overall inspection effect of pipeline inspection.

[0004] However, the above-mentioned device requires the pipe to be placed inside the detection ring during use, which requires a lot of effort to lift the pipe. After the detection, it is also necessary to remove the pipe with great effort, which is very laborious. Therefore, we propose a pressure pipe wall thickness detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the pipe needs to be placed inside the detection ring, which requires a lot of effort to lift the pipe and then remove it after the detection, which is very laborious. Therefore, a pressure pipe wall thickness detection device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pressure pipeline wall thickness detection device, comprising:

[0008] Mounting plate;

[0009] Two side panels are slidably mounted on both sides of the mounting plate;

[0010] The moving mechanism, mounted on the mounting plate, is used to control the horizontal movement of the two side plates towards each other;

[0011] The testing mechanism, located at the bottom of the mounting plate, is used for wall thickness testing;

[0012] The limiting mechanism, located on the two side plates, is used to clamp onto the pressure pipeline;

[0013] Multiple casters are installed at the bottom of the two side panels.

[0014] Preferably, the moving mechanism includes a dual-axis motor fixedly mounted on the top of the mounting plate, with screws fixedly mounted on both output shafts of the dual-axis motor, and the threads on the two screws having opposite directions.

[0015] Preferably, each of the two screws is threaded with a push-pull plate, and the two push-pull plates are fixedly connected to the two side plates respectively.

[0016] Preferably, rectangular grooves are provided on both sides of the mounting plate, and rectangular plates are fixedly installed on the side of the two side plates that are close to each other. The outer sides of the two rectangular plates are slidably connected to the inner walls of the two rectangular grooves respectively.

[0017] Preferably, the detection mechanism includes an electric push rod fixedly installed at the bottom of the mounting plate, and a thickness detection head is fixedly installed on the output shaft of the electric push rod.

[0018] Preferably, a wall thickness gauge is fixedly installed on one of the two side plates, and the wall thickness gauge and the thickness detection head are connected by the same transmission connection line.

[0019] Preferably, the limiting mechanism includes a mounting bracket slidably mounted on one side of the two side plates, a rotating roller rotatably mounted on the inner side of each mounting bracket, a fixing plate fixedly mounted on one side of each of the two side plates, a cylinder fixedly mounted on the bottom of each fixing plate, and the output shafts of the two cylinders fixedly connected to the top of the two mounting brackets respectively.

[0020] Preferably, a sliding groove is provided on one side of each of the two side plates, and a sliding block is fixedly installed on one side of each of the two mounting brackets. The outer side of the sliding block is slidably connected to the inner wall of the sliding groove, and a guide rod is fixedly installed in the sliding groove. The sliding block and the guide rod are slidably connected.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] The pressure pipe simply needs to be placed on the ground, and then the entire device is moved using multiple casters to position the pressure pipe between the two side plates. A dual-axis motor drives two screws to rotate, causing two push-pull plates to bring the two side plates closer together. This ensures that the multiple rotating rollers on the two mounting brackets are in contact with the pressure pipe, preventing misalignment during movement. An electric push rod moves the thickness detection head downwards, bringing it into contact with the outer surface of the pressure pipe. The wall thickness detector is then activated to quickly detect the wall thickness of the pressure pipe and display it to the user. Finally, the entire device is pushed along the outside of the pressure pipe to detect the thickness at different locations.

[0023] During testing, the pressure pipe only needs to be placed on the ground to complete the wall thickness test at different locations of the pressure pipe. The pressure pipe does not need to be moved up or down, saving time and effort. Attached Figure Description
