Description

Technical Field

[0001] This utility model relates to the field of pressure testing technology in steel-plastic composite pipe production, specifically to a pressure detector that can be clamped on both sides. Background Technology

[0002] Steel-plastic composite pipe is a new type of composite pipe, also known as plastic-coated steel pipe. Plastic-coated steel pipes include internally plastic-coated steel pipes, externally plastic-coated steel pipes, both internally and externally plastic-coated steel pipes, externally galvanized and internally plastic-coated steel pipes, and externally 3PE anti-corrosion and internally plastic-coated steel pipes, etc. It combines the advantages of steel pipes and plastic pipes, possessing excellent properties such as high strength, corrosion resistance, wear resistance, high temperature resistance, and aging resistance. It is an upgraded replacement product for traditional pipelines. Compared with traditional steel pipes, steel-plastic composite pipes are lighter, easier to install, and have a longer service life, saving significant time and costs. Compared with plastic pipes, steel-plastic composite pipes have higher strength and better corrosion resistance, allowing for long-term use in harsh environments without aging, deformation, or cracking.

[0003] After production, steel-plastic composite pipes need to be randomly sampled for pressure testing. This testing requires testing not only the pressure on the outside but also the pressure on the inside. However, existing pressure detectors are relatively simple in their testing methods and cannot quickly clamp the composite pipes on both sides. Therefore, there is an urgent need for a pressure detector that can clamp the pipes on both sides to overcome these shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a pressure detector that can be clamped on both sides, which has the advantages of good clamping effect and convenient detection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure detector capable of being clamped on both sides, comprising a detector assembly, a clamping and fixing assembly, a limiting assembly, and a pressure inflation pump. The clamping and fixing assembly is disposed on the front of the detector assembly, and the limiting assemblies are disposed on both sides of the top of the clamping and fixing assembly. The pressure inflation pump is disposed on the left side of the left limiting assembly. The detector assembly includes a base, an L-shaped mounting seat, a control terminal, a cylinder, and a pressure sensor body. The clamping and fixing assembly includes a receiving seat, a dual-axis motor, a first sliding groove, a slider, a threaded rod, a moving rod, a threaded groove, an L-shaped card seat, and a rubber sealing plate. The limiting assembly includes an arc-shaped seat, an arc-shaped top plate, a limiting slide rod frame, a sliding column, a second sliding groove, and a spring.

[0006] Furthermore, the L-shaped mounting base is fixedly installed on the top of the base, the control terminal is fixedly installed on the right side of the L-shaped mounting base, the cylinder is fixedly installed on the top of the L-shaped mounting base, and the pressure sensor body is located at the bottom of the L-shaped mounting base.

[0007] Furthermore, the bottom of the cylinder extends through to the bottom of the L-shaped mounting base and is fixedly connected to the top of the pressure sensor body. The top of the pressure sensor body is electrically connected to the top of the control terminal via a wire. The receiving seat is fixedly installed at the center of the top of the base, and a dual-axis motor is fixedly installed at the center of the inner cavity of the receiving seat.

[0008] Furthermore, movable rods are provided on both sides of the inner cavity of the receiving seat, and two first sliding grooves are opened on the front and back of the inner cavity of the receiving seat. A slider is slidably connected inside the first sliding groove, and the side of the slider that is relatively close to the slider is fixedly connected to both sides of the movable rod.

[0009] Furthermore, the movable rod has a threaded groove inside, and a threaded rod is rotatably connected inside the threaded groove. The two sides of the dual-axis motor are fixedly connected to the side of the threaded rod that is relatively close to it. An L-shaped bracket is fixedly installed on the top of the movable rod.

[0010] Furthermore, a rubber sealing plate is fixedly installed on the relatively close side of the L-shaped card holder, and the arc-shaped seats are all fixedly installed on both sides of the top of the receiving seat. A limiting slide rod frame is slidably connected at the center inside the arc-shaped seat, and an arc-shaped top plate is fixedly installed at the bottom of the limiting slide rod frame.

[0011] Furthermore, the second slide grooves are all opened on both sides inside the arc-shaped seat, and a slide column is slidably connected inside the second slide groove. The bottom of the slide column is fixedly connected to the top of the arc-shaped top plate. A spring is sleeved on the surface of the limiting slide rod frame. The right side of the pressure air pump passes through the left L-shaped card seat and extends to the right side of the left rubber sealing plate.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention uses a detector assembly to detect the pressure on the outside of the steel-plastic composite pipe, a pressure inflation pump to detect the air pressure inside the pipe, a clamping and fixing assembly to fix both sides, and a limiting assembly to initially fix the pipe. In use, the steel-plastic composite pipe is first placed on top of the receiving seat, and the limiting slide bar is released. Under the action of the spring, the limiting slide bar moves the sliding column downwards, initially fixing the top of the steel-plastic composite pipe with the arc-shaped top plate. After fixing, the dual-axis motor is turned on, driving the threaded rod to rotate, causing the moving rod to move... The inner side moves and is fixed on both sides of the steel-plastic composite pipe under the action of the rubber sealing plate. After fixing, the cylinder is opened, and the pressure sensor body moves downward through the cylinder. Under the action of the pressure sensor body, the pressure on the steel-plastic composite pipe is monitored. When detecting the air pressure inside the steel-plastic composite pipe, the pressure inflation pump is turned on to inflate the air pressure inside the steel-plastic composite pipe, thereby further detecting its pressure. It has the advantages of good fixing and clamping effect and convenient detection, which solves the problem that the pressure detector of the existing technology is relatively simple in detection and cannot quickly fix and clamp the composite pipe on both sides.

A dual-axis motor 22 is fixedly installed at the center of the inner cavity of the receiving seat 21. More specifically, by setting the control terminal 13, it is electrically connected to the pressure sensor body 15, the pressure inflation pump 4, the dual-axis motor 22 and the cylinder 14 via wires, thereby controlling the energized equipment.

[0024] In some embodiments, movable rods 26 are provided on both sides of the inner cavity of the receiving seat 21.

More specifically, the slider 24 is limited by the first sliding groove 23 to prevent the slider 24 from shaking during movement. The movable rod 26 is limited by the slider 24 to prevent the movable rod 26 from shaking during movement.

Under the action of the spring 36, the limiting slide rod 33 drives the slide column 34 to move downward, so that the arc-shaped top plate 32 initially fixes the top of the steel-plastic composite pipe. After fixing, turn on the dual-axis motor 22. The dual-axis motor 22 drives the threaded rod 25 to rotate, so that the moving rod 26 moves inward and fixes the two sides of the steel-plastic composite pipe under the action of the rubber sealing plate 29.

[0030] Step 2: After fixing, open cylinder 14. Cylinder 14 drives pressure sensor body 15 to move downward. Under the action of pressure sensor body 15, the pressure on the steel-plastic composite pipe is monitored. When detecting the air pressure inside the steel-plastic composite pipe, turn on pressure inflation pump 4 to inflate the air pressure inside the steel-plastic composite pipe, thereby further detecting its pressure. It has the advantages of good fixing and clamping effect and convenient detection.
