Description

Technical Field

[0001] This utility model relates to the field of pressure resistance testing technology for plastic pipes, specifically a pressure resistance testing instrument for plastic pipes used in engineering construction supervision. Background Technology

[0002] The plastic pipe pressure resistance tester is a testing device used for long-term pressure resistance and instantaneous burst tests of plastic and composite pipes. It features test parameter setting, real-time monitoring, data acquisition and analysis, automatic recording of test pressure and pressure resistance time, automatic testing after setting the pressure resistance time, and continuous operation. In engineering construction, it is necessary to use this tester to randomly inspect the plastic pipes used in the project, primarily to determine the pressure resistance value of the pipes. This is mainly to prevent the use of pipes that cannot achieve the required strength, resulting in substandard structural strength in the engineering project.

[0003] Furthermore, the application document with publication number CN215640569U mentions a pressure resistance tester for plastic pipes used in engineering construction supervision. This tester, equipped with a slide rail, slider, and sleeve, works by placing the pipe on a support plate after the sensor is installed. Activating the first telescopic rod moves the support plate upwards until the pipe contacts the sensor, detecting the pressure on the pipe. Simultaneously, the slider moves within the slide rail, following the support plate's movement, thus restricting the support plate and preventing wobbling that could cause data errors. This effectively solves the current problems encountered in engineering construction... The pressure testing instrument for plastic pipes used in this project has several drawbacks. First, it lacks a structure to limit the movement of the plastic pipes, making them prone to slippage and displacement during testing, thus compromising stability and reliability. Second, the testing platform is too high, making loading and unloading large-diameter engineering plastic pipes difficult.

[0004] Therefore, it is necessary to design a pressure resistance tester for plastic pipes used in engineering construction supervision to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a pressure resistance tester for plastic pipes used in engineering construction supervision. This instrument can limit the movement of plastic pipes, ensuring their stability and reliability during the testing process. Furthermore, the pressure resistance testing platform has a low height, making loading and unloading easier, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pressure resistance tester for plastic pipes used in engineering construction supervision includes a main instrument control system platform and a pressure resistance testing structure. The pressure resistance testing structure includes a movable base assembly, a support and limiting column, a mounting and fixing frame, a pressing hydraulic telescopic mechanism, and a pressing lifting platform assembly. The movable base assembly includes a base body, a lower measuring mold base, and a plastic pipe limiting clamp. The plastic pipe limiting clamp includes a first arc-shaped fixing clamp base and a second arc-shaped fixing clamp base that are symmetrically distributed and fixedly installed on the top surface of the lower measuring mold base. The inner walls of the first arc-shaped fixing clamp base and the second arc-shaped fixing clamp base are respectively movably mounted with the first clamp body and the second clamp body through the positioning hydraulic telescopic mechanism.

[0008] As a preferred embodiment of this utility model, the mounting frame is fixedly installed on the top of the movable base assembly by a support limiting column, and the pressing lifting platform assembly is movably installed between the mounting frame and the movable base assembly. At the same time, the movable base assembly, the mounting frame, and the pressing lifting platform assembly are arranged in parallel.

[0009] As a preferred embodiment of this utility model, universal wheels with locking devices are movably installed at the four corners of the bottom of the base body, and the first clamp body and the second clamp body are respectively adapted to the two sides of the outer surface of the plastic pipe.

[0010] As a preferred embodiment of this utility model, the pressing lifting platform assembly includes a lifting platform body and a measuring upper mold base for mounting pressure sensors, and the measuring upper mold base for mounting pressure sensors is fixedly installed at the center of the bottom surface of the lifting platform body.

[0011] As a preferred embodiment of this utility model, the lifting platform body is provided with a matching limiting sliding hole near the supporting limiting column.

[0012] As a preferred embodiment of this utility model, the diameter of the upper mold base for measuring the pressure sensor is slightly smaller than the inner diameter of the plastic pipe limiting clamp.

[0013] Beneficial Effects: This invention addresses the shortcomings of existing pressure testing instruments for plastic pipes used in engineering construction supervision. Firstly, by activating the positioning hydraulic telescopic mechanism, the first and second clamping bodies move closer to the plastic pipe until they are clamped, effectively preventing slippage and displacement during testing and ensuring stability and reliability. Secondly, the overall structure of the pressure testing platform lowers the platform height, making loading and unloading easier, thus solving the problems mentioned in the background.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A pressure resistance tester for plastic pipes used in engineering construction supervision includes a main instrument control system platform 1 and a pressure resistance testing structure 2. The pressure resistance testing structure 2 includes a movable base assembly 21, a support and limiting column 22, a mounting and fixing frame 23, a pressing hydraulic telescopic mechanism 24, and a pressing lifting platform assembly 25.

[0025] Specifically, the movable base assembly 21 includes a base body 211, a measuring lower mold base 212, and a plastic tube limiting clamp 213. The plastic tube limiting clamp 213 includes a first arc-shaped fixing clamp seat 2131 and a second arc-shaped fixing clamp seat 2132, which are symmetrically distributed and fixedly installed on the top surface of the measuring lower mold base 212. The inner walls of the first arc-shaped fixing clamp seat 2131 and the second arc-shaped fixing clamp seat 2132 are respectively movably mounted with a first clamp body 2134 and a second clamp body 2135 through a positioning hydraulic telescopic mechanism 2133. The mounting and fixing frame 23 is fixedly installed on the top of the movable base assembly 21 through a supporting limiting column 22, and the lifting platform is pressed. The assembly 25 is movably installed between the mounting frame 23 and the movable base assembly 21. The movable base assembly 21, the mounting frame 23, and the pressing lifting platform assembly 25 are arranged in parallel. By activating the positioning hydraulic telescopic mechanism 2133, the first clamp body 2134 and the second clamp body 2135 are driven to move closer to the plastic pipe until they are clamped, achieving a limiting effect. This effectively prevents the plastic pipe from slipping and shifting during the measurement process, ensuring the stability and reliability of the plastic pipe during the measurement process. At the same time, the overall structure of the pressure testing structure body 2 makes the pressure testing platform lower, making loading and unloading easier.

[0026] Preferably, universal wheels 2111 with locking devices are movably installed at the four corners of the bottom of the base body 211, and the first clamp body 2134 and the second clamp body 2135 are respectively adapted to both sides of the outer surface of the plastic pipe. The universal wheels 2111 with locking devices can make the pressure testing structure body 2 move and position. At the same time, setting the first clamp body 2134 and the second clamp body 2135 to be adapted to both sides of the outer surface of the plastic pipe can greatly improve the limiting effect and make it more stable.

[0027] Preferably, the pressing lifting platform assembly 25 includes a lifting platform body 251 and a measuring upper mold base 252 equipped with a pressure sensor. The measuring upper mold base 252 equipped with the pressure sensor is fixedly installed at the center of the bottom surface of the lifting platform body 251. Under the action of the pressing hydraulic telescopic mechanism 24, the pressing lifting platform assembly 25 moves downward until the measuring upper mold base 252 equipped with the pressure sensor contacts the plastic pipe. While gradually applying pressure, the pressure value is detected in real time, thereby realizing its pressure resistance test.

[0028] Preferably, the lifting platform body 251 has a matching limiting sliding hole 2511 through it near the supporting limiting column 22, and the limiting sliding hole 2511 can make the lifting platform body 251 remain stable under the action of the supporting limiting column 22 during the lifting process, and prevent shaking.

[0029] Preferably, the diameter of the upper mold base 252 for mounting the pressure sensor is slightly smaller than the inner diameter of the plastic pipe limiting clamp 213. Setting the diameter of the upper mold base 252 for mounting the pressure sensor to be slightly smaller than the inner diameter of the plastic pipe limiting clamp 213 can make the pressure application more concentrated and the data more accurate.

[0030] In summary, this utility model can limit the position of plastic pipes, ensuring the stability and reliability of plastic pipes during the testing process. At the same time, the pressure testing platform has a low height, making loading and unloading easier.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
