Description

Technical Field

[0001] The invention relates to the technical field of pipeline seismic support, and in particular to a pipeline seismic support bending resistance testing device. Background Art

[0002] Pipeline seismic support is a special support designed to protect pipeline systems from natural disasters such as earthquakes. It reliably connects the pipeline system to the building structure to reduce pipeline displacement, vibration and stress concentration caused by earthquakes, thereby ensuring the safety and integrity of the pipeline system. When an earthquake occurs, the seismic support can reduce the vibration and displacement of the pipeline, reduce the risk of pipeline damage caused by earthquakes, and thus maintain the integrity and functionality of the pipeline system.

[0003] Earthquake-resistant supports are mostly used to support and fix pipelines, so there are certain requirements for their earthquake-resistant performance. When existing earthquake-resistant support detection devices detect earthquake-resistant supports, general detection equipment can only perform earthquake-resistant load tests in a single direction, which makes the detection of earthquake-resistant supports have certain limitations, and the detection effect of earthquake-resistant supports is also relatively general, which cannot simulate the use effect of earthquake-resistant supports during a real earthquake.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, the Chinese patent with the authorization announcement number CN117213785B discloses a seismic performance detection device for a seismic support. The device can more comprehensively detect the seismic performance of the seismic support during use by performing a horizontal and vertical bidirectional seismic load test on the seismic support. At the same time, it can also avoid the limitations caused by a single-direction seismic load test. In addition, through a bidirectional simulated seismic load test, the use and stress state of the seismic support during an earthquake can be more realistically simulated and restored, and the detection restoration degree and detection accuracy are higher. However, in actual production operations, when the above-mentioned device is used, it is difficult to perform bending tests according to different types of pipeline seismic brackets. Often, only a single bending test can be performed. The test item is single, and when other tests are required, additional separate accessories need to be used, and the test efficiency is low. At the same time, during the test, only a bending force test can be performed in a single direction, and it is difficult to detect the bending force on both sides at the same time, and the detection efficiency is low.

[0042] The specific working steps of a pipeline seismic support bending resistance test device are as follows: First, after starting the side motor body 402, the left threaded rod 403 is driven to rotate after the side motor body 402 is started. Through the connection of the connecting rod 404, after the left threaded rod 403 is started, the right threaded rod 405 can be synchronously driven to rotate.

The surfaces of the rotating right threaded rod 405 and the left threaded rod 403 are both threadedly connected by a threaded ring 408, and the thread directions of the left threaded rod 403 and the right threaded rod 405 are opposite. When the right threaded rod 405 and the left threaded rod 403 rotate symmetrically, the two threaded rings 408 will be synchronously driven to move toward each other along the top of the side support frame 407. Through the connection of the horizontal moving plate 409, the threaded ring 40 When 8 is moved, the pressure tester body 4013 and the clamping arc plate 4014 are synchronously driven to move horizontally, and the horizontal moving plate 409 will drive the side sliding block 4010 to slide horizontally along the surface of the side sliding groove 4012 during the horizontal movement, which can improve the stability of the horizontal moving plate 409 during the movement. By continuously moving the clamping arc plate 4014, the clamping arc plate 4014 can be pushed to move to the surface of the pipe support body 3, and a thrust is generated on the surface of the pipe support body 3. The thrust value generated will be recorded by the pressure tester body 4013. At this time, observe whether the surface of the pipe support body 3 is bent, and measure whether the bending resistance of the pipe support body 3 meets the standard. Through automatic clamping, no manual operation is required. At the same time, by synchronously testing the bending degree of both sides of the pipe support body 3, the test efficiency can be improved. At the same time, after the clamping arc plate 4014 is moved to fit the surface of the pipe support body 3, the clamping plate 506 on the surface of the right extension block 503 is rotated, and the clamping plate 506 is rotated ninety degrees along the surface of the side limit plate 504, so that one side of the clamping plate 506 can fit the inner side of the clamping groove 502. At this time, the clamping plate 506 will be limited by the clamping groove 502 on the surface of the left extension block 501. After the limit, the two sides of the pipe support body 3 will be set on the inner side of the clamping arc plate 4014 and the clamping plate 506. At this time, by driving the left threaded rod 403 and the right threaded rod 405 to rotate in opposite directions, the two threaded rings 408 will be driven to move outward after rotation, so that the pipe support body 3 can be subjected to a tensile test without the use of additional equipment, thereby improving the comprehensiveness of the detection; At the same time, after the bending degree detection is carried out, after the bottom motor body 602 is started, the side transmission rod 603 is driven to rotate by the bottom motor body 602, and the rotating side transmission rod 603 will drive the side transmission plate 604 to rotate along one end of the side transmission rod 603, and the rotating side transmission plate 604 will drive the side movable rod 605 to rotate, and the rotating side movable rod 605 will drive the transmission sleeve plate 606 to move, and the sleeve connection between the sleeve ring 607 provided on one side of the transmission sleeve plate 606 and the inner limit rod 608 can drive the side limit block 609 on the side of the inner limit rod 608 to move horizontally when the transmission sleeve plate 606 moves, and the horizontally moving side limit block 609 will drive the side translation plate 60 10 reciprocates, and the top connecting block 6011 on the top of the side translation plate 6010 can be continuously driven to move horizontally through the continuous rotation of the bottom motor body 602. The horizontally moving top connecting block 6011 will drive the test bench 2 to reciprocate, and when the side translation plate 6010 moves horizontally along the inner side of the base 1, the sliding of the bottom sliding block 6012 and the bottom sliding rail 6013 can improve the stability of the side translation plate 6010 moving horizontally along the inner side of the base 1, reduce the deviation generated during the movement, and improve the stability of the movement. By quickly driving the test bench 2 to reciprocate, the stability of the pipeline support body 3 in use and the deviation generated when it is vibrated can be tested, thereby improving the detection effect; At the same time, when the bottom motor body 602 drives the side transmission rod 603 to rotate, it will synchronously drive the bottom gear disc 701 to rotate. The rotating bottom gear disc 701 will drive the meshing transmission belt 702 to rotate. The rotating transmission belt 702 will drive the top gear disc 703 to rotate. One side of the rotating top gear disc 703 is movably connected and supported on one side of the bottom support frame 708 through the bottom bearing disc 707. Through the rotation of the top gear disc 703, the top fixed rod 704 is synchronously driven to rotate. The rotating top fixed rod 704 will drive the side fixed rod 705 to rotate. The rotating side fixed rod 705 drives the side friction brush 706 to continuously rub the surface of the pipe support body 3. Through continuous friction, the wear resistance of the surface material of the pipe support body 3 can be detected, thereby improving the comprehensiveness and effect of the detection.
