Description

Technical Field

[0002] Bellows compensators (also known as bellows expansion joints or flexible joints) are devices used to absorb axial, lateral, and angular displacements in piping systems caused by factors such as temperature changes, pressure fluctuations, and installation errors. They are widely used in the oil, gas, chemical, shipbuilding, and heating industries. To ensure the quality and performance of bellows compensators, in-process testing is crucial. Designing a testing device for bellows compensator production should be able to comprehensively and accurately evaluate various performance characteristics, including dimensional accuracy, material properties, sealing, and pressure resistance.

[0003] According to a disclosed bellows compensator detection auxiliary device (publication number: CN 216283268 U), it includes: a sealing plate, an arc plate, a compensating tube, a screw, a nut, a hydraulic cylinder, and a booster pump. Compared with the existing technology, the utility model has the following beneficial effects: the design adds a sealing plate, an arc plate, a compensating tube, a screw, a nut, a hydraulic cylinder, and a booster pump. The design achieves sealing inside the compensating tube through the sealing plate, and extends into the interior of the arc plate through the screw.

[0004] When the bellows compensator is being tested, including air pressure testing, the bellows compensator may experience displacement and shaking during the air pressure testing process. The displacement and shaking will affect the detection of the bellows compensator. Through the mutual cooperation between the above-mentioned compensating tubes, screws, nuts and other components, it is difficult to automatically perform a series of clamping actions, and it is difficult to clamp both sides of the bellows compensator at the same time. It is difficult to ensure the stability of the bellows compensator during the detection process, and it needs to be improved. Utility Model Content

The two clamping rods can clamp both sides of the bellows compensator at the same time, which not only ensures the stability of the bellows compensator during the detection process, but also prevents the offset or uneven pressure that may be caused by unilateral clamping, thereby ensuring the accuracy and consistency of the detection process.

[0018] 2.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, this embodiment proposes a detection device for the production of corrugated compensators, including a base plate 1, a universal wheel 2 is provided at the bottom of the base plate 1, a detection fixture 3 is provided at the top of the base plate 1, the detection fixture 3 includes a spring 1 31, one end of the spring 1 31 is fixedly connected to the top of the base plate 1, the end of the spring 1 31 away from the base plate 1 is fixedly connected to the detection platform 32, the bottom of the detection platform 32 is fixedly connected to an extrusion rod 34, the top of the base plate 1 is fixedly connected to a support 35, a turntable 36 is rotatably connected to the inner wall of the support 35, a short rod 37 is fixedly connected to the circumferential surface of the turntable 36, a long rod 38 is fixedly connected to the circumferential surface of the turntable 36, the end of the long rod 38 away from the turntable 36 is fixedly connected to a clamping rod 39, the top of the base plate 1 is fixedly connected to a rectangular rod 312, the top of the rectangular rod 312 is provided with an air pressure detector 313, and the side of the air pressure detector 313 is penetrated by a detection tube 6.

[0029] There are two clamping rods 39, supports 35, turntables 36, short rods 37, and extrusion rods 34, and they are symmetrical to each other along the vertical center axis of the detection table 32. There are two of them, which can clamp both sides of the corrugated compensator at the same time to further reduce displacement.

[0030] There are several springs 31, which are arranged in groups of two and are symmetrical with each other along the vertical center axis of the detection platform 32. The top of the base plate 1 is fixedly connected to a limit rod 33, and the end of the limit rod 33 away from the base plate 1 passes through the bottom of the detection platform 32. The design of the limit rod 33 is conducive to limiting the displacement trajectory of the detection platform 32.

[0031] The testing platform 32 is located on the displacement track of the clamping rod 39, the air pressure detector 313 is located on the side of the testing platform 32, and the short rod 37 is located on the displacement track of the extrusion rod 34. The testing platform 32 is used to place the corrugated compensator. The testing platform 32 is located on the displacement track of the clamping rod 39, so the corrugated compensator can be clamped, which is beneficial to prevent the corrugated compensator from displacement.

[0032] The side of the support 35 is fixedly connected to an L-shaped rod 310, and the side of the L-shaped rod 310 is fixedly connected to a second spring 311. The end of the second spring 311 away from the L-shaped rod 310 is fixedly connected to the side of the long rod 38. The design of the second spring 311 is conducive to the automatic reset of the turntable 36 when the short rod 37 is not squeezed.

[0033] In this embodiment, the bellows compensator uses an air pressure detector 313 to detect the air pressure of the bellows compensator. The bellows compensator that needs to be tested is placed on the testing platform 32. The bellows compensator has a certain gravity. A spring 31 is set at the bottom of the testing platform 32. Therefore, when the bellows compensator is placed on the testing platform 32, gravity will squeeze the testing platform 32 downward, causing the testing platform 32 to move downward. The downward movement of the testing platform 32 will drive the squeezing rod 34 to move downward. The short rod 37 is located on the movement trajectory of the squeezing rod 34. When the squeezing rod 34 moves downward, it will squeeze the short rod 37, squeezing the short rod 37 to move downward. The downward movement of the short rod 37 will drive the turntable 36 to rotate downward, driving the turntable 36 to rotate toward the side close to the testing platform 32. The downward rotation of the turntable 36 will drive the long rod 38 and the clamping rod 39 to rotate downward, causing the clamping rod 39 to move toward the side close to the testing platform 32. At this time, the bellows compensator is placed On the testing table 32, the clamping rod 39 will clamp the bellows compensator. There are two clamping rods 39. This operation is performed on both sides at the same time. The two clamping rods 39 will clamp both sides of the bellows compensator at the same time. The air pressure of the bellows compensator is accurately monitored by the air pressure detector 313, and the performance of the bellows compensator can be more accurately tested. This air pressure detection method can help ensure that the bellows compensator can withstand and adapt to the required pressure requirements in actual use, thereby improving product quality control. When the bellows compensator is placed on the testing table 32, the entire system will automatically perform a series of clamping actions, reducing the complexity and errors of manual operations. The two clamping rods 39 can clamp both sides of the bellows compensator at the same time, which not only ensures the stability of the bellows compensator during the detection process, but also prevents offset or uneven pressure that may be caused by unilateral clamping, thereby ensuring the accuracy and consistency of the detection process.

[0034] Example 2

[0035] like Figures 3 to 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes another embodiment, a test bench cleaning device 4 is provided on the top of the base plate 1, and the test bench cleaning device 4 includes a support rod 41, one end of the support rod 41 is fixedly connected to the side of the base plate 1, and a motor 42 is fixedly connected to the side of the support rod 41, and a switch 43 is provided on the top of the motor 42. A threaded rod 44 is fixedly connected to the output shaft of the motor 42, and a threaded sleeve 45 is threadedly connected to the circumferential surface of the threaded rod 44. The top of the threaded sleeve 45 is fixedly connected to a vertical rod 47, and the top of the vertical rod 47 is fixedly connected to a connecting rod 48. The end of the connecting rod 48 away from the vertical rod 47 is fixedly connected to a fan 49, and a rotating shaft 410 passes through the side of the turntable 36, and one end of the rotating shaft 410 is fixedly connected to a disc 411, and a touch rod 412 is fixedly connected to the circumferential surface of the disc 411. The fan 49 is used to blow air left and right to remove dust on the test bench 32.

[0036] The switch 43 is located on the displacement track of the trigger rod 412. A round rod 46 is fixedly connected to the side of the support rod 41. The end of the round rod 46 away from the support rod 41 passes through the side of the threaded sleeve 45. The switch 43 is located on the displacement track of the trigger rod 412, which is conducive to squeezing the switch 43 and starting the motor 42 when the trigger rod 412 is displaced.

[0037] The detection platform 32 is located on the displacement trajectory of the fan 49, the fan 49 is located on the side of the detection platform 32, the fan 49 is located on the side of the air pressure detector 313, and the fan 49 is located on the side of the detection platform 32, which is conducive to allowing the wind generated by the fan 49 to blow onto the detection platform 32.

[0038] A display screen 5 is provided on the side of the air pressure detector 313, a button is provided on the side of the air pressure detector 313, two support rods 41 are provided, and they are symmetrical to each other along the vertical center axis of the threaded rod 44. The design of the display screen 5 is conducive to directly observing the test results of the corrugated compensator.

[0039] There are a number of universal wheels 2, which are arranged in groups of two and are symmetrical to each other along the vertical center axis of the base plate 1. The base plate 1 is made of metal. The design of the universal wheels 2 facilitates the movement of the entire device.

[0040] When the test is completed, the corrugated compensator is removed from the test platform 32. Without the pressure of gravity, the test platform 32 will automatically reset, and the squeezing rod 34 will not continue to squeeze the short rod 37. The short rod 37 will drive the rotary disk 36 to automatically reset through the elastic force of the spring 2 311, and drive the rotary disk 36 to rotate to the side away from the test platform 32. At this time, the rotation of the rotary disk 36 will drive the rotating shaft 410 to rotate, so that the rotating shaft 410 rotates to the side away from the test platform 32. The rotation of the rotating shaft 410 will drive the disc 411 to rotate. The rotation of the disc 411 will drive the trigger rod 412 to rotate to the side away from the test platform 32. The switch 43 of the motor 42 is located on the motion trajectory of the trigger rod 412. When the trigger rod 412 rotates, it will squeeze the switch 43, start the motor 42, and the rotation of the motor 42 will drive the threaded rod 4 4 rotates, and the rotation of the threaded rod 44 will drive the threaded sleeve 45 to move left and right on the threaded rod 44. The left and right movement of the threaded sleeve 45 will drive the vertical rod 47 and the connecting rod 48 to move left and right. The left and right movement of the connecting rod 48 will drive the fan 49 to move left and right. The fan 49 is located on the side of the detection table 32. The fan 49 will blow air on the surface of the detection table 32. At this time, the corrugated compensator has been removed from the detection table 32. The fan 49 is used to blow air to remove dust on the surface of the detection table 32 and reduce the impact of dust on the detection of the next corrugated compensator. The design of the fan 49 is such that after each detection is completed, it can automatically blow air to clean the dust on the surface of the detection table 32. This is very critical for the detection of the corrugated compensator, because dust may interfere with the detection process and affect the detection accuracy. The automatic blowing function can effectively reduce the accumulation of dust, thereby improving the detection accuracy and ensuring that the environment for each detection is as clean as possible.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
