Description

Technical Field

[0001] This utility model relates to the field of insulating flange testing technology, specifically to a device for testing the insulation performance of flanges. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected together as a combined sealing structure. Pipe flanges refer to flanges used for piping in pipeline installations; on equipment, they specifically refer to the inlet and outlet flanges of the equipment.

[0003] CN221726168U discloses a device for testing the insulation performance of flanges. Addressing the problem that the testing methods proposed in the background are inefficient and difficult to apply to large-scale flange insulation testing, the following solution is proposed: a base with an electric rotary table mounted on its top outer wall. The output shaft of the electric rotary table is connected to a transfer sprocket conveyor. A feeding sprocket conveyor is located on one side of the transfer sprocket conveyor, and a discharging sprocket conveyor is located on the other side. This invention can automatically complete the feeding and discharging process, saving material change time and meeting the requirements for large-scale flange body insulation testing. Utilizing the predetermined height difference between two insulation test pins, the insulation performance of the flange body can be quickly measured, replacing the complexity of manual testing and greatly improving the efficiency of insulation testing.

[0004] When testing flanges, the insulation performance testing device typically stands the flanges upright on the conveying device. However, because some insulating flanges are long and thin, the lack of a limiting device during the conveying and testing process can cause the flanges to tilt, affecting the testing efficiency. Therefore, it is necessary to design a flange insulation performance testing device to improve the above problems. Utility Model Content

[0028] In the following description, embodiments of the present invention for testing the insulation performance of flanges will be described with reference to the accompanying drawings.

[0029] Figure 1-4 This invention illustrates an embodiment of a flange insulation performance testing device, comprising:

[0030] The system comprises a conveying frame 1 and an insulating flange body 7. Two conveying rollers 2 are rotatably connected to the inner cavity of the conveying frame 1, and the two conveying rollers 2 are connected by two conveying chains 3. Multiple conveying assemblies 4 are fixedly mounted on the surfaces of the two conveying chains 3. The insulating flange body 7 is placed on top of the conveying assemblies 4, which are driven by the conveying chains 3 in a cyclical manner. Specifically, the conveying assembly 4 includes a mounting plate 41 fixed to the surface of the conveying chains 3 by bolts. Two brackets 42 are detachably mounted on the top of the mounting plate 41. The top of the brackets 42 has grooves 43 that mate with the insulating flange body 7. Furthermore, two mounting posts 44 are welded to the bottom of the brackets 42. The top of the mounting plate 41 has multiple mounting holes 45 that mate with the mounting posts 44. Nuts are threaded onto the surface of the mounting posts 44, locking them into the inner cavity of the mounting plate 41. Specifically, positioning rollers 46 are mounted on both the left and right sides of the bottom of the mounting plate 41. Fixed brackets 8 are fixedly mounted on both the left and right sides of the inner cavity of the conveying frame 1. The mounting plate 41 slides on the surface of the fixed brackets 8. Guide grooves for the positioning rollers 46 are provided on the surface of the fixed brackets 8. A U-shaped frame 5 is mounted above the conveying frame 1. A test plate assembly 6 is located inside the U-shaped frame 5 and slides up and down within the inner cavity of the U-shaped frame 5. Specifically, the test plate assembly... Component 6 includes a movable plate 61 that slides up and down inside the U-shaped frame 5. A cylinder 9 is fixedly installed on the top of the U-shaped frame 5. The output end of the cylinder 9 extends into the inner cavity of the U-shaped frame 5 and is fixedly installed with the movable plate 61. Depending on the model of the insulating flange body 7, the cylinder 9 needs to be adjusted before testing so that the extension length of the cylinder 9's output end is such that the bottom of the test pen assembly 62 makes contact with the insulating flange body 7 for testing. A test assembly is installed on the surface of the movable plate 61. The test assembly consists of a test gauge 64 and two test pen assemblies 62. The test pen assemblies 62 are movably installed inside the movable plate 61, and the test gauge 64 is fixedly installed on the surface of the movable plate 61. Specifically... The test pen assembly 62 includes a test pen 621, a sliding block 622 fixedly mounted on the surface of the test pen 621, a sliding groove 63 for the sliding block 622 to move in the inner cavity of the movable plate 61, a plurality of slots 66 on the top of the movable plate 61, and insert rods 623 detachably connected to both sides of the sliding block 622. The insert rods 623 extend through the inner cavity of the slots 66 to the inner cavity of the sliding block 622. The insert rods 623 and the sliding block 622 can be connected by plugging or threading. Specifically, rollers 65 are rotatably connected to both sides of the movable plate 61, and limit grooves 10 are opened on both sides of the inner cavity of the U-shaped frame 5. The rollers 65 roll in the inner cavity of the limit grooves 10.

[0031] When in use, this flange insulation performance testing device can be used in conjunction with an automatic feeding device and an automatic unloading device to place the insulating flange body 7 onto the conveying assembly 4, and automatically unload the insulating flange body 7 after the test is completed.

[0032] Working Principle: In use, the user places the insulating flange bodies 7 one by one on top of the bracket 42. The two grooves 43 stably support both ends of the insulating flange bodies 7. The conveyor roller 2 drives the conveyor chain 3, causing the mounting plate 41 to slide along the surface of the fixed bracket 8. At this time, the positioning roller 46 rolls within the guide groove of the fixed bracket 8, thus conveying the insulating flange bodies 7 towards the U-shaped frame 5. When the insulating flange bodies 7 reach the bottom of the U-shaped frame 5, the sensor at the bottom of the movable plate 61 controls the conveyor roller 2 to stop conveying and controls the cylinder 9 to slide the movable plate 61 downwards. At this time, the roller 65 rolls within the limit groove 10, causing the test pen assembly 62 to move downwards to test the surface of the insulating flange bodies 7. After the test, the conveyor roller 2 is restarted to continue conveying the insulating flange bodies 7.

[0033] In summary, this flange insulation performance testing device uses the conveying assembly 4 to laterally lift the insulating flange body 7 and transport it one by one to the bottom of the U-shaped frame 5. In conjunction with the downward movement of the test plate assembly 6, the insulating flange body 7 is tested one by one, which improves the stability of the insulating flange body 7 during testing and thus improves the testing efficiency.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
