Description

A pipeline pressure resistance testing device Technical Field

[0001] This utility model relates to the field of pipeline pressure resistance testing equipment, and in particular to a pipeline pressure resistance testing equipment. Background Technology

[0002] Plastic pipes are widely used in construction, water supply and drainage, chemical and other fields due to their advantages such as light weight, corrosion resistance and convenient construction. However, the compressive strength of plastic pipes is an important factor affecting their service life and safety.

[0003] Currently, the testing methods for the compressive strength of plastic pipes mostly involve squeezing the pipes with pressure equipment to detect the pressure at which the pipes will crack. Since pipe cracking is usually observed manually, it is not possible to accurately detect the pressure that caused the cracking to begin, resulting in inaccurate compressive strength test data and being time-consuming and labor-intensive. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the aforementioned problems in the prior art, this utility model provides a pipe pressure resistance testing device that can more conveniently and efficiently test the pressure resistance of plastic pipes and more accurately observe at what pressure the pipe begins to crack, thereby obtaining more accurate pressure resistance values.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] A pipeline pressure resistance testing device includes a placement platform, a frame, a pressure applying mechanism, a fixing mechanism, and a crack monitoring mechanism. The pressure applying mechanism is connected to the placement platform via the frame, the crack monitoring mechanism is connected to the placement platform, and the fixing mechanism is provided in the middle of the placement platform.

[0009] The crack monitoring mechanism includes a visual sensor, a lighting lamp, a controller, and a data processing unit. Several visual sensors are provided on both sides of the frame. The visual sensors are all electrically connected to the data processing unit. The controller is connected to the pressure application mechanism, the data processing unit, and the visual sensors. The lighting lamp is provided next to each visual sensor and is connected to the frame.

[0010] Furthermore, the pressure applying mechanism includes a linear drive, an extrusion head, and a pressure sensor. The linear drive is disposed on the upper part of the frame and is linearly driven connected to the upper part of the extrusion head. The pressure sensor is disposed on the lower part of the extrusion head, and both the pressure sensor and the pressure sensor are electrically connected to the controller.

[0013] Furthermore, it also includes a slide bar, with a slide bar provided on both sides of the upper part of the extrusion head, and a sliding hole adapted to the slide bar provided on the frame, and a slide bar and a sliding hole are slidably connected.

[0014] (III) Beneficial Effects

[0015] The beneficial effects of this invention are as follows: When it is necessary to test the compressive strength of plastic pipes, the pipe can be placed on a platform and then fixed on the platform by a fixing mechanism. A vision sensor is then activated to collect raw values ​​and images of the pipe's outer surface, and a light is turned on to make the images clearer. A pressure-applying mechanism is then activated to pressurize the pipe, causing it to deform under pressure. When the pressure reaches a certain value, cracks begin to appear in the pipe. During this process, the vision sensor monitors both sides of the pipe in real time, and the collected data is uploaded to the data processing unit for analysis. When cracks appear in the pipe, the controller stops the pressure-applying mechanism to pressurize the pipe, determining the pressure at which cracks appear. Through multiple experiments, a more accurate compressive strength value is obtained. This allows for more convenient and efficient compressive strength testing of plastic pipes, and more accurate observation of the pressure at which cracks begin to appear, thus obtaining a more accurate compressive strength value.

[0021] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to Figures 1 to 3. The pipeline pressure resistance testing device of this utility model includes a placement platform 9, a frame 1, a pressure applying mechanism 2, a fixing mechanism, and a crack monitoring mechanism. The pressure applying mechanism 2 is connected to the placement platform 9 through the frame 1. The crack monitoring mechanism is connected to the placement platform 9. The fixing mechanism is provided in the middle of the placement platform 9.

[0023] The crack monitoring mechanism includes a vision sensor 7, a lighting lamp 8, a controller 6, and a data processing unit. Several vision sensors 7 are provided on both sides of the frame 1. Each vision sensor 7 is electrically connected to the data processing unit. The controller 6 is connected to the pressure application mechanism 2, the data processing unit, and the vision sensors 7. Each vision sensor 7 is provided with a lighting lamp 8, which is connected to the frame 1.

[0024] The working principle of this utility model is as follows: When it is necessary to test the compressive strength of a plastic pipe, the pipe can be placed on the placement platform 9 and then fixed on the placement platform 9 by the fixing mechanism. Then, the vision sensor 7 is activated to collect the original values ​​and images of the outer surface of the pipe, and the lighting lamp 8 is turned on to make the obtained image clearer. Then, the pressure applying mechanism 2 is activated to pressurize the pipe and the pipe deforms under pressure. When the pressure reaches a certain value, the pipe begins to crack. During this process, the vision sensor 7 monitors both sides of the pipe in real time, and the data is uploaded to the data processing unit for analysis. When the pipe begins to crack, the controller 6 stops the pressure applying mechanism 2 to pressurize the pipe, obtains the amount of pressure applied to the crack, and obtains a more accurate compressive strength value through multiple experiments.

[0025] Furthermore, the pressure applying mechanism 2 includes a linear drive 202, an extrusion head 203, and a pressure sensor 204. The linear drive 202 is disposed on the upper part of the frame 1 and is linearly driven connected to the upper part of the extrusion head 203. The pressure sensor 204 is disposed on the lower part of the extrusion head 203. Both the pressure sensor 204 and the pressure sensor 205 are electrically connected to the controller 6.

[0026] As can be seen from the above description, when it is necessary to pressurize the pipeline, the linear drive 202 can be operated to compress the pipeline through the extrusion head 203, and the pressure sensor 204 can detect the pressure value of the extrusion during the extrusion process, so as to better combine the subsequent cracking data to determine at what pressure value the pipeline will crack.

[0027] Furthermore, the fixing mechanism includes a clamping plate 5 and a bolt 4. Both ends of the clamping plate 5 are provided with a through hole, and a bolt 4 is inserted into each through hole. The placement platform 9 is provided with a threaded hole that matches the bolt 4. The bolt 4 and the threaded hole are detachably connected.

[0028] As can be seen from the above description, when it is necessary to fix the pipe, the clamp 5 can be passed through the middle of the pipe and pressed against the inner wall of the pipe. Then, it can be connected to the threaded hole on the placement platform 9 by bolt 4, so that the pipe can be fixed with the cooperation of the placement platform 9 and the clamp 5, and prevent the pipe from shifting during the pressure application process.

[0029] Furthermore, the crack monitoring mechanism also includes an alarm 3, which is connected to the controller 6 and is used to issue an alarm signal when a crack occurs in the pipeline.

[0030] As can be seen from the above description, it is beneficial that an alarm can be triggered when cracks appear, allowing operators to observe the pipeline condition in a timely manner.

[0031] Furthermore, it also includes a slide rod 201. A slide rod 201 is provided on both sides of the upper part of the extrusion head 203. The frame 1 is provided with a sliding hole adapted to the slide rod 201. A slide rod 201 and a sliding hole are slidably connected.

[0032] As can be seen from the above description, this facilitates a more stable lifting and lowering of the extrusion head 203 via the slide bar 201. Example 1
