Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, and more specifically, to a testing device for seismic bracing. Background Technology

[0002] Seismic bracing is a type of component or device that limits the displacement of pipelines, controls pipeline vibration, and transfers loads to the load-bearing structure. During an earthquake, seismic bracing should provide reliable protection for building electromechanical facilities and withstand seismic forces from any horizontal direction. To ensure the quality of seismic bracing, it is necessary to conduct inspections on it.

[0003] In existing technologies, seismic bracing is typically tested by vibrating the pipeline and then assessing its tensile strength, fatigue resistance, and cyclic loading. However, this only tests the strength of the seismic bracing and not its effectiveness. As is well known, the vibration amplitude of pipelines closer to the seismic bracing is smaller, while that of pipelines farther away is larger. If a large number of seismic bracings are used, it will increase construction costs. If a small number of seismic bracings are used, the distance between them on the pipeline will be too large, resulting in poor seismic resistance in the middle of the pipeline. Therefore, a device for detecting pipeline vibration amplitude is needed to determine the distance between seismic bracings and the number of seismic bracings to be installed, so as to ensure seismic resistance while reducing construction costs. Utility Model Content

[0004] The purpose of this invention is to solve the problem of detecting pipeline vibration amplitude, and a detection device for seismic supports has been designed.

[0005] To achieve the above objectives, the technical solution of this utility model is a testing device for seismic bracing, comprising a holding platform, a holding plate above the holding platform, the holding plate being mounted on the holding platform by multiple support rods, seismic bracing being installed on both sides of the lower end of the holding plate, the seismic bracing being able to fix the pipe, and an amplitude detection mechanism being provided above the holding platform.

[0006] The amplitude detection mechanism includes a movable frame installed on a holding platform. A sleeve is installed on the movable frame and is fitted onto the outside of the pipe. Multiple movable telescopic rods are installed on the sleeve. When the pipe vibrates, the telescopic rods can be pushed outward. The telescopic rods are provided with scale lines.

[0007] Furthermore, the movable frame includes rotating screws installed on both sides of the sleeve. A screw sleeve is threadedly connected to the outside of the rotating screw, and the screw sleeve is connected to the sleeve through a fixing rod. Screw bearings are installed at both ends of the rotating screw, and the screw bearings are installed on the holding platform through a support shaft. A transmission wheel is installed at one end of the rotating screw, and the transmission wheels on the two rotating screws are connected by a transmission belt. A servo motor is installed on one side of the upper end of the holding platform, and the servo motor is connected to one end of a rotating screw.

[0008] Furthermore, the sleeve has multiple square through holes, which are evenly distributed in a circle around the central axis of the sleeve. The telescopic rod is a square rod that passes through the square through holes, and a friction pad is installed inside the square through holes.

[0009] Furthermore, a limiting sleeve installed on the sleeve is provided on the outside of the square through hole.

[0010] Furthermore, a reset mechanism is also installed on the sleeve. The reset mechanism includes multiple moving blocks located on the outside of the sleeve. A connecting rod is installed at the end of the telescopic rod away from the sleeve. A fixed pulley is provided on one side of the telescopic rod and installed on the sleeve. A connecting rope is tied to the connecting rod. One end of the connecting rope passes around the fixed pulley and connects to the moving block. Multiple limiting slides are installed on the outside of the sleeve. One end of the moving block extends into the limiting slide.

[0011] Furthermore, a movable tube is fitted onto the outer side of the sleeve, and the movable tube is located between the movable block and the telescopic rod.

[0012] The beneficial effects of this utility model are as follows: Pipes are installed on a support plate using seismic bracing. Mechanical equipment is used to strike and vibrate the pipes. During vibration, the pipes come into contact with the telescopic rods, which can then be pushed outwards. The distance the telescopic rods have moved can be observed using scale lines. After the pipes stop vibrating, the amplitude of the vibration can be easily determined using scale lines. A movable frame can move the sleeve, allowing for the detection of vibration amplitude at multiple locations on the pipes. By changing the striking force of the mechanical equipment, the amplitude of the pipes at different forces can be determined. By changing the distance between the seismic bracing members, the amplitude of the pipes at different distances can be determined, thus enabling comprehensive detection of pipe vibration amplitude. By using multiple detection data points and rationally distributing the seismic bracing members, both seismic resistance and construction costs can be reduced. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] This utility model provides, for example Figure 1-6The device shown is a testing device for seismic bracing, including a holding platform 1, a holding plate 2 on top of the holding platform 1, the holding plate 2 being mounted on the holding platform 1 by multiple support rods 3, seismic bracing 4 being installed on both sides of the lower end of the holding plate 2, the seismic bracing 4 being able to fix the pipe, and an amplitude detection mechanism being provided above the holding platform 1; the amplitude detection mechanism includes a movable frame 5 mounted on the holding platform 1, a sleeve 6 being mounted on the movable frame 5, the sleeve 6 being fitted onto the outside of the pipe, and multiple movable telescopic rods 7 being mounted on the sleeve 6, which can push the telescopic rods 7 outward when the pipe vibrates, and the telescopic rods 7 are provided with scale lines.

[0023] The process of this device for detecting pipeline vibration is as follows: The pipeline is installed on the holding plate 2 through two anti-vibration supports 4, and the pipeline passes through the inside of the sleeve 6. The sleeve 6 can be moved to various positions on the pipeline by the moving frame 5. The telescopic rod 7 is pushed towards the pipeline, and one end of the telescopic rod 7 contacts the pipeline. The pipeline is struck by external mechanical equipment, causing the pipeline to vibrate. When the pipeline vibrates, it pushes the telescopic rod 7 outward. The distance the telescopic rod 7 moves can be determined by the scale lines, and thus the amplitude of the pipeline can be judged. By changing the position of the sleeve 6, the striking force of the mechanical equipment, and the distance between the two anti-vibration supports 4, the shaking of the pipeline under various conditions can be simulated, and the amplitude can be detected, thereby ensuring the anti-vibration effect.

[0024] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 4 The movable frame 5 includes rotating screws 8 installed on both sides of the sleeve 6. A screw sleeve 9 is threadedly connected to the outside of the rotating screw 8. The screw sleeve 9 is connected to the sleeve 6 through a fixing rod 10. Screw bearings 11 are installed at both ends of the rotating screw 8. The screw bearings 11 are installed on the holding platform 1 through a support shaft 12. A transmission wheel 13 is installed at one end of the rotating screw 8. The transmission wheels 13 on the two rotating screws 8 are connected through a transmission belt 14. A servo motor 15 is installed on one side of the upper end of the holding platform 1. The servo motor 15 is connected to one end of a rotating screw 8.

[0025] The process of the moving frame 5 driving the sleeve 6 to move is as follows: Start the servo motor 15 to rotate. The servo motor 15 can drive a rotating screw 8 to rotate. The transmission wheel 13 on the two rotating screws 8 is connected by the transmission belt 14, which can make the two rotating screws 8 rotate synchronously. Through the connection between the rotating screw 8 and the screw sleeve 9, the screw sleeve 9, the support shaft 12 and the sleeve 6 can move.

[0026] Refer to the instruction manual appendix Figure 6The sleeve 6 has multiple square through holes 16, which are evenly distributed in a circle around the central axis of the sleeve 6. The telescopic rod 7 is a square rod that passes through the square through holes 16. A friction pad 17 is installed inside the square through holes 16. The telescopic rod 7 can be limited through the square through holes 16. The friction pad 17 can increase the friction between the telescopic rod 7 and the sleeve 6, so that the telescopic rod 7 will not move when it is not subjected to external force.

[0027] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 4 Instruction manual attached Figure 5 Included with instruction manual Figure 6 A limiting sleeve 18 is provided on the outside of the square through hole 16 and installed on the sleeve 6. The telescopic rod 7 can be limited by the limiting sleeve 18.

[0028] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The sleeve 6 is also equipped with a reset mechanism, which includes multiple moving blocks 19 located on the outside of the sleeve 6. A connecting rod 20 is installed at the end of the telescopic rod 7 away from the sleeve 6. A fixed pulley 21 is provided on one side of the telescopic rod 7 and installed on the sleeve 6. A connecting rope 22 is tied to the connecting rod 20. One end of the connecting rope 22 passes around the fixed pulley 21 and connects to the moving block 19. Multiple limiting slides 23 are installed on the outside of the sleeve 6. One end of the moving block 19 extends into the limiting slide 23.

[0029] The reset mechanism resets the telescopic rod 7 as follows: Under normal conditions, one end of the telescopic rod 7 is against the outside of the pipe, the moving block 19 is in the position furthest from the telescopic rod 7, and the connecting rope 22 is taut. When the pipe vibrates, the telescopic rod 7 can be pushed outward and the connecting rope 22 can be pulled. By changing the direction of the pulling force through the fixed pulley 21, the moving block 19 can be pulled closer to the telescopic rod 7 when the telescopic rod 7 moves outward. The limiting slide 23 can ensure the direction of movement of the moving block 19. After the test is completed, the staff pulls the moving block 19 back to its original position. Under the action of the connecting rope 22, the telescopic rod 7 can be pulled closer to the pipe, thereby resetting the telescopic rod 7.

[0030] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The sleeve 6 is fitted with a movable tube 24, which is located between the movable block 19 and the telescopic rod 7.
