[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5This utility model provides an infrared hot-melt pipe butt testing device, including a base 1. A support platform 2 is bolted to the upper surface of the base 1. A clearance opening 3 is provided in the middle of the support platform 2. A multi-stage hydraulic cylinder 4 is bolted to the upper surface of the base 1. The output end of the multi-stage hydraulic cylinder 4 passes through the clearance opening 3 and is bolted to a top plate 5. Multiple side rods 7 are bolted to one side of the upper surface of the support platform 2. The top of each side rod 7 is bolted to a square telescopic rod 8. One end of each square telescopic rod 8 is bolted to a horizontal plate 9. A linear motor module 10 is bolted to the lower surface of the horizontal plate 9. Two pressure sensors 11 for testing pressure are bolted to the lower surface of the mover on the linear motor module 10. A pressure plate 12 for contacting the pipe body is bolted to the lower surface of the two pressure sensors 11. The upper surface of the horizontal plate 9 is provided with a device that works in conjunction with the pressure sensors 11. The display screen 13 and the top plate 5 are bolted together with a support frame 6 for supporting the pipe body. The support frame 6 has a V-groove for positioning the pipe body. Multiple ends below the pressure plate 12 are rotatably connected to rollers 20 through bearings. The outer circumference of the rollers 20 is bonded with elastic rubber rings. Then, the multi-stage hydraulic cylinder 4 is activated to extend, thereby moving the top plate 5 upward. As the top plate 5 moves upward, the support frame 6 on it moves upward. At the same time, the support frame 17 is moved upward through the connecting rod 21. After the support frame 6 contacts the infrared hot melt pipe body, the multi-stage hydraulic cylinder 4 is activated again to extend, lifting the infrared hot melt pipe body until it is in close contact with the rollers 20. Through the linear motor module 10 and the pressure sensor 11 on it, the docking position of the infrared hot melt pipe body can be repeatedly measured without manual inspection, which effectively increases the accuracy of the inspection.

[0024] In this utility model, both sides of the top plate 5 are fixedly connected with connecting rods 21 by bolts. Both ends of the upper surface of the support platform 2 are fixedly connected with a set of circular telescopic rods 15 by bolts, and there are multiple rods in each set. The top ends of the multiple circular telescopic rods 15 in each set are fixedly connected with the top plate 16 by bolts. The other ends of the two connecting rods 21 are fixed to one side of the top plate 16. The upper surface of the top plate 16 is fixedly connected with a support frame 17 that is uniform in height and shape with the support frame 6. When the top plate 5 moves upward, the support frame 6 on it moves upward, and the support frame 17 moves upward through the connecting rods 21. Through the connecting rods 21 and the support frame 17, the infrared hot melt pipe body can be lifted up and its two ends can be supported, effectively preventing the product from falling due to tilting during the inspection process.

[0025] In this invention, two spring dampers 18 are located on the upper surface of the support platform 2, between one support frame 6 and two support frames 17. The top of the spring dampers 18 is fixedly connected to a bracket 19 by bolts. The upper surface of the bracket 19 has a V-shaped groove similar to the upper surface of the support frame 6. In use, the infrared hot melt pipe body to be tested is first placed on the two brackets 19. After the measurement is completed, the multi-stage hydraulic cylinder 4 is activated to retract, thereby moving the infrared hot melt pipe body downward until it falls on the bracket 19. The extension and retraction continue until the support frame 6 and the support frame 17 are separated from the infrared hot melt pipe body. With the spring dampers 18 and the brackets 19 on them, when the support frame 6 and the support frame 17 are below, the infrared hot melt pipe is placed on them first. The space for manual movement is large, which facilitates the placement and removal of the infrared hot melt pipe.

[0026] In this invention, a fixing plate is bolted between the two side rods 7 located in the middle position. An electric push rod 14 is bolted to the fixing plate, and the output end of the electric push rod 14 is fixed to one side of the horizontal plate 9. After the infrared hot melt pipe body is sent to the bracket 19, the electric push rod 14 is activated to retract, thereby driving the horizontal plate 9 to move towards the side rods 7. When the components on it are removed from the range of the infrared hot melt pipe body, the infrared hot melt pipe body can be removed, thus completing the inspection of the connection of the infrared hot melt pipe body. By connecting the horizontal plate 9 to the electric push rod 14, it can be moved. During the placement and removal of the infrared hot melt pipe, the horizontal plate 9 is moved to one side, further providing more room for workers to move.

[0027] The use of this utility model involves the following steps:

[0028] S1: When using, first place the infrared hot melt pipe body to be tested on the two brackets 19, then start the multi-stage hydraulic cylinder 4 to extend it, thereby driving the top plate 5 to move upward. When the top plate 5 moves upward, the bearing frame 6 on it moves upward. At the same time, the connecting rod 21 drives the bearing frame 17 to move upward. When the bearing frame 16 contacts the infrared hot melt pipe body, continue to start the multi-stage hydraulic cylinder 4 to extend it, and lift the infrared hot melt pipe body until it is in close contact with the roller 20.

[0029] S2: After the infrared hot melt pipe body and the roller 20 are in close contact, the pressure sensor 11 is subjected to force and the pressure it receives is displayed on the display screen 13. Then, the linear motor module 10 is started to drive the roller 20 to move laterally to measure the pipe. When passing the docking part, if the value displayed on the display screen 13 fluctuates within the normal range, the docking is perfect. If the value on the display screen 13 fluctuates too much, there is a difference in the docking.

[0030] S3: After the measurement is completed, start the multi-stage hydraulic cylinder 4 to retract, thereby moving the infrared hot melt pipe body downward until it falls on the bracket 19. Continue to extend and retract until the support frame 1 6 and support frame 2 17 are separated from the infrared hot melt pipe body.

[0031] S4: Then start the electric push rod 14 to retract, thereby driving the horizontal plate 9 to move towards the side rod 7. When the components on it are out of the range of the infrared hot melt pipe body, the infrared hot melt pipe body can be removed, thus completing the detection of the connection of the infrared hot melt pipe body.

[0032] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
