Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PE pipes, and specifically relates to a strength detection device for PE pipes. Background Art
[0002] As is well known, during the actual use of pipes, due to diverse usage environments, in order to enable the pipes to still be used normally in harsh environments, it is necessary to strictly detect the quality of the pipes before leaving the factory. And the strength detection of pipes is the most important part of controlling the pipe quality. The existing strength detection of PE pipes requires testing the impact force on the PE pipes.
[0003] Testing the impact force on PE pipes requires the use of impact equipment. The existing impact equipment places the punch at a certain height, and then the punch falls from a high place to impact the PE pipe to test the impact force on the PE pipe. However, after the punch of the existing impact equipment contacts the PE pipe, the punch will rebound. After the punch rises due to the rebound force, it will hit the PE pipe multiple times. The PE pipe being impacted by the punch multiple times will affect the accuracy of the PE pipe detection. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-4 , a strength detection device for a PE pipe of the present utility model, including a detection table 1 and a support frame 2 arranged on its top. A plurality of sliding rods 3 are arranged on the top of the support frame 2 and a mounting frame 4 slidably connected to the sliding rods 3. A plurality of detachable weights 6 are installed on the mounting frame 4. The tester adjusts the impact force of the impact component by replacing, increasing or decreasing the weights 6, making the range of the impact force wider and improving the practicability. One of the installation methods is that there is a mounting rod 5 on the mounting frame 4, and the weight 6 is installed on the mounting rod 5, which is convenient for the disassembly and installation of the weight 6. A nut 7 is installed on the mounting rod 5, and the nut 7 fixes the weight 6. An impact component is arranged at the bottom of the mounting frame 4. The impact component falls from a high place to impact the PE pipe. The impact component is detachably connected to the mounting frame 4. The impact component includes a punch 9 and a connecting rod 8. The impact component is equipped with various models, and different models of punches 9 can be replaced to conduct different impact tests. A through groove 10 is arranged in the middle of the support frame 2, and the through groove 10 can allow the impact component to pass through;
[0025] A telescopic device 11 is arranged on the support frame 2. The telescopic device 11 is an electric telescopic rod or other telescopic devices such as a telescopic cylinder. A limit stop block 13 for restricting the upward movement of the punch 9 is arranged at the telescopic end of the telescopic device 11. A sensor 12 for detecting the mounting frame 4 is arranged on the support frame 2. The sensor 12 controls the telescopic movement of the telescopic device 11. When the mounting frame 4 and the punch 9 fall, after the mounting frame 4 moves in place, it will trigger the sensor 12. After the sensor 12 is triggered, it controls the telescopic device 11 to extend. The telescopic device 11 extends to make the limit stop block 13 move towards the through groove 10. The limit stop block 13 blocks the punch 9. The limit stop block 13 prevents the punch 9 from rebounding and moving upward, so as to effectively prevent the punch 9 from rebounding and prevent the punch 9 from impacting the PE pipe multiple times. It is common technical knowledge for those skilled in the art that the telescopic device 11 extends after the sensor 12 is triggered, and this patent will not elaborate. The selected control system can be a single-chip microcomputer, a PLC, etc.
[0026] Wherein, a buffer pad 14 is arranged at the top of the punch 9 or the bottom of the limit stop block 13 to prevent the direct contact between the punch 9 and the limit stop block 13. The buffer pad 14 can effectively weaken the impact force between the punch 9 and the limit stop block 13.
[0027] Among them, a towing rope 15 is installed on the top of the mounting frame 4. The mounting frame 4 and the impact assembly can be lifted by using the towing rope 15. Towing can be carried out by a tractor or manually.
[0028] Among them, a support pad 16 is arranged on the top of the mounting frame 4 to prevent the mounting frame 4 and the support frame 2 from directly contacting each other, effectively weakening the impact force between the mounting frame 4 and the support frame 2.
[0029] In summary, when using this strength detection device for PE pipes, place the PE pipe at the bottom of the support frame 2, align the position to be detected with the through groove 10, lift the mounting frame 4 to a specified height, and then let the mounting frame 4 fall. The punch 9 passes through the through groove 10 and impacts the PE pipe. After the mounting frame 4 moves into place, it will trigger the sensor 12. After the sensor 12 is triggered, it controls the telescopic device 11 to extend. The extension of the telescopic device 11 causes the limit stop 13 to move towards the through groove 10. The limit stop 13 blocks the punch 9, and the limit stop 13 prevents the punch 9 from moving upward after rebounding, thereby effectively preventing the punch 9 from rebounding and preventing the punch 9 from impacting the PE pipe multiple times.
