Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe pressure testing devices, in particular to a PE pipe pressure testing device. Background Technique

[0002] PE pipes, namely polyethylene pipes, are widely used. Among them, water supply pipes and gas pipes are two of their largest application markets. When processing PE pipes, no heavy metal salt stabilizers are added. The material is non-toxic, has no scaling layer, and does not breed bacteria, which can well solve the secondary pollution of urban drinking water.

[0003] As disclosed in a utility model with the authorization announcement number CN210037473U, a PE pipe pressure testing device includes a support base and a PE pipe. Two side plates, two columns and an electronic scale main body are installed at the top end of the support base. The columns are located on both sides of the electronic scale main body, and the side plates are located on both sides of the columns. A positioning seat is installed at the top end of the column, and a positioning groove is provided on the positioning seat. Both ends of the PE pipe are placed on the positioning groove. A cylinder switch is installed on the front end face of the side plate, a cylinder is installed at the center of the top end of the top plate, the output end of the cylinder is connected with a piston rod, and one end of the piston rod is bolted with a pressing head. In this utility model, when the cylinder switch is turned on, the cylinder starts to work. The cylinder drives the piston rod to expand and contract, so that the pressing head presses the PE pipe on the top end of the electronic scale main body, which is convenient for the staff to observe the deformation of the PE pipe. At the same time, by observing the liquid crystal display screen on the front end face of the electronic scale main body, the pressure value can be obtained, which is very intuitive and the operation is simple and convenient. However, when this device is in use, it cannot continuously perform pressure tests on multiple positions of a longer PE pipe. Even if it is necessary to disassemble, manually move the position of the PE pipe and fix it, then it can perform pressure tests on multiple positions of the PE pipe well, thus affecting the overall test efficiency of the PE pipe.

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following combines specific embodiments to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present utility model. Embodiment

[0019] Please refer to Figures 1-4 As shown, the present utility model provides a PE pipe pressure testing device. The anti-slip buffer pad 12 is made of rubber material, which can clamp and fix the PE pipe 16 well, and at the same time can also play a certain protective role for the PE pipe 16. An electronic scale main body 13 is arranged on the workbench 1. A display screen 14 is arranged on one side of the electronic scale main body 13, and an arc plate 15 is arranged at the upper end of the electronic scale main body 13. The PE pipe 16 is placed on the upper end of the arc plate 15, and the size of the arc plate 15 is relatively large, which can place PE pipes 16 of different sizes well. A bracket 17 is fixedly connected to the upper end of the workbench 1. An electric telescopic rod 18 is arranged at the upper end of the bracket 17. The output end of the electric telescopic rod 18 is fixedly connected with a pressing block 19. Support legs 20 are fixedly connected to the lower end corners of the workbench 1.

[0020] During use, place the PE pipe 16 on the arc-shaped plate 15, then start the electric telescopic rod 18. The electric telescopic rod 18 drives the pressing block 19 to move downward, and the pressing block 19 presses the PE pipe 16 on the arc-shaped plate 15 at the top of the electronic scale main body 13, facilitating direct observation of the deformation of the PE pipe 16 by the staff. At the same time, the pressure value can be obtained by observing the display screen 14 on the front end face of the electronic scale main body 13, which is very intuitive.

[0021] As a further implementation manner of this embodiment, as Figures 1-5 shown, a pair of fixing plates 2 are fixedly connected to the lower end of the workbench 1. The two fixing plates 2 are symmetrically arranged. A motor 3 is arranged on one side of the fixing plate 2. The output end of the motor 3 penetrates through the fixing plate 2 and is fixedly connected to a bidirectional lead screw 4. One end of the bidirectional lead screw 4 is rotatably connected to the fixing plate 2. A pair of connecting plates 5 are threadedly connected to the bidirectional lead screw 4. A pair of limiting holes 6 are formed on the workbench 1. A pair of limiting plates 7 are fixedly connected to the upper ends of the connecting plates 5. One end of the limiting plate 7 penetrates through the limiting hole 6 and is fixedly connected to a U-shaped plate 8. The limiting hole 6 can play a role in limiting the limiting plate 7. A driving device 10 is arranged at the upper end of the U-shaped plate 8. The output end of the driving device 10 penetrates through the U-shaped plate 8 and is fixedly connected to a conveying roller 11. One end of the conveying roller 11 is rotatably connected to the U-shaped plate 8. An anti-slip and shock-absorbing pad 12 is arranged on the conveying roller 11.

[0022] During use, by starting the motor 3, the motor 3 drives the bidirectional lead screw 4 to rotate. The rotation of the bidirectional lead screw 4 drives the two connecting plates 5 to move. The movement of the connecting plates 5 drives the two pairs of limiting plates 7 to move. The limiting plates 7 can move more stably under the limiting action of the limiting holes 6, so as to drive the two pairs of U-shaped plates 8 and the conveying rollers 11 on the U-shaped plates 8 to move until the anti-slip and shock-absorbing pads 12 on the four conveying rollers 11 clamp and fix the PE pipe 16, thus facilitating subsequent pressure testing of the PE pipe 16. When it is necessary to perform pressure testing on another position of the PE pipe 16, the driving device 10 can be started simultaneously. The driving device 10 drives the conveying roller 11 and the anti-slip and shock-absorbing pad 12 on the conveying roller 11 to rotate together, thereby driving the PE pipe 16 to move along the arc-shaped plate 15 to one side. When the PE pipe 16 moves to a suitable position, the driving device 10 is turned off, so that pressure testing can be performed on another position of the PE pipe 16. With this device, it is relatively convenient to perform pressure testing on multiple positions of the PE pipe 16, improving the overall testing efficiency of the PE pipe 16.

[0023] Specific working principle: During use, first place the PE pipe 16 on the arc-shaped plate 15 at the top of the electronic scale main body 13. By starting the motor 3, the motor 3 drives the bidirectional lead screw 4 to rotate. The rotation of the bidirectional lead screw 4 drives the two connecting plates 5 to move. The movement of the connecting plates 5 drives the two pairs of limiting plates 7 to move. The limiting plates 7 can move more stably under the limiting action of the limiting holes 6, thereby driving the two pairs of U-shaped plates 8 and the conveying rollers 11 on the U-shaped plates 8 to move until the anti-slip and buffer pads 12 on the four conveying rollers 11 clamp and fix the PE pipe 16. Then start the electric telescopic rod 18. The electric telescopic rod 18 drives the pressing block 19 to move downward, and the pressing block 19 presses the PE pipe 16 on the arc-shaped plate 15 at the top of the electronic scale main body 13, which is convenient for the staff to directly observe the deformation of the PE pipe 16. At the same time, the pressure value can be obtained by observing the display screen 14 on the front end face of the electronic scale main body 13, which is very intuitive. When it is necessary to conduct a pressure test on another position of the PE pipe 16, the driving device 10 can be started simultaneously. The driving device 10 drives the conveying rollers 11 and the anti-slip and buffer pads 12 on the conveying rollers 11 to rotate together, thereby driving the PE pipe 16 to move along the arc-shaped plate 15 to one side. When the PE pipe 16 moves to a suitable position, turn off the driving device 10, so that a pressure test can be conducted on another position of the PE pipe 16. With this device, it is relatively convenient to conduct pressure tests on multiple positions of the PE pipe 16, improving the overall test efficiency of the PE pipe 16.
