Description

Technical Field

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

[0002] Seismic bracing is a support system that reduces the risk of pipeline swaying or falling during earthquakes by restraining the horizontal displacement of electromechanical facilities such as water pipes, air ducts, cable trays, and gas pipelines, thereby ensuring personnel safety and reducing economic losses.

[0003] The accessories for seismic bracing systems include structural steel, threaded rods, and pipe clamps. The seismic bracing systems are mainly installed through the threaded connection between the threaded rods and nuts. Therefore, the firmness of the connection between the threaded rods and nuts is an important criterion for judging whether the seismic bracing systems are qualified. Thus, the threaded rods and nuts need to be installed on a fixed object through the threaded connection, and then a vibration test is conducted on the threaded rods. After the test, the stability of the nut connection needs to be checked to determine which type of threaded rod to use. Utility Model Content

[0004] The purpose of this invention is to solve the problem of whether the connection between the threaded rod and the nut is stable after a shaking test. A threaded rod testing fixture for seismic supports has been designed.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a threaded rod testing fixture for seismic bracing supports includes a worktable, on which multiple height-adjustable support rollers are mounted. The threaded rod can be placed on the support rollers. A movable limiting frame is mounted on the worktable, and a limiting block is placed on the limiting frame. The limiting block has a circular through hole, and a limiting nut is detachably mounted on one end of the limiting block. The limiting nut and the circular through hole are concentrically corresponding. The limiting block and the limiting nut are threadedly connected to one end of the threaded rod. A drive frame is mounted on the upper surface of the worktable, and a testing sleeve is mounted on the drive frame. A testing nut is threadedly connected to the threaded rod, and the testing nut can extend into the testing sleeve.

[0006] Furthermore, the limiting frame includes a movable platform located above the worktable, with guide blocks installed on both sides of the upper end of the movable platform, and limiting slides installed on both sides of the upper surface of the worktable. One end of the guide block extends into the limiting slide, and a square groove is formed on the upper end of the movable platform.

[0007] Furthermore, a fixing block is installed on the upper surface of the worktable, and the fixing block and the moving table are connected by a return spring.

[0008] Furthermore, the limiting block is a cuboid block, the lower end of which can be placed in a square groove and cannot rotate within the square groove, and a nut holding groove is opened on one side of the upper end of the cuboid block, and the limiting nut is placed in the nut holding groove and cannot rotate.

[0009] Furthermore, the limiting nut is hexagonal in shape, and there are multiple models of the limiting nut. The limiting nuts of the various models are the same in shape and size, but the threaded holes of the various models are different in size.

[0010] Furthermore, the drive frame is a DC motor mounted on the workbench, and the detection sleeve is mounted on the rotating end of the DC motor.

[0011] Furthermore, the detection nut is available in multiple models, with the same external size but different thread hole sizes inside.

[0012] The beneficial effects of this utility model are as follows: The threaded rod and the test nut are installed on the limiting block through a threaded connection. The limiting block is used to simulate a fixed object. After the threaded rod and nut have undergone a vibration test, the limiting block is placed on the limiting frame. Then, the test nut is extended into the test sleeve. The test sleeve is rotated by the drive frame. If the force of the drive frame rotating the test sleeve is insufficient to loosen the test nut, it indicates that the connection between the threaded rod and the nut is not problematic, and this type of threaded rod is sufficient to ensure the stability of the seismic support. If the force of the drive frame rotating the test sleeve causes the test nut to loosen, it indicates that this type of threaded rod is insufficient to ensure the stability of the seismic support, and a thicker threaded rod is needed to ensure the quality of the seismic support.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] 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.

[0016] This utility model provides, for example Figure 1-3 The tooling shown is for testing threaded rods of seismic bracing, including a worktable 1, on which multiple height-adjustable support rollers 2 are mounted. The threaded rod can be placed on the support rollers 2. A movable limiting frame 3 is mounted on the worktable 1, and a limiting block 4 is placed on the limiting frame 3. The limiting block 4 has a circular through hole 5. A limiting nut 6 is detachably mounted on one end of the limiting block 4. The limiting nut 6 and the circular through hole 5 are concentrically corresponding. The limiting block 4 and the limiting nut 6 are connected to one end of the threaded rod by a threaded connection. A drive frame 7 is mounted on the upper surface of the worktable 1, and a testing sleeve 8 is mounted on the drive frame 7. A testing nut 9 is connected to the threaded rod by a thread, and the testing nut 9 can extend into the testing sleeve 8.

[0017] The process of testing the threaded rod using this device is as follows: Install the limiting block 4 and the limiting nut 6 at one end of the threaded rod. Then, screw the testing nut 9 onto one side of the limiting block 4 and tighten it. This will fix the limiting block 4 in place through the testing nut 9 and the limiting nut 6. Next, conduct a vibration test on the threaded rod. After the test, place the limiting block 4 on the threaded rod inside the limiting frame 3 and place the testing nut 9 inside the testing sleeve 8. Then, drive the testing sleeve 8 to rotate via the drive frame 7. If the force of the drive frame 7 in rotating the testing sleeve 8 is insufficient to loosen the testing nut 9, it indicates that the connection between the threaded rod and the testing nut 9 is correct, and this type of threaded rod is sufficient to ensure the stability of the seismic bracing. If the force of the drive frame 7 in rotating the testing sleeve 8 causes the testing nut 9 to loosen, it indicates that this type of threaded rod is insufficient to ensure the stability of the seismic bracing, and a thicker threaded rod is required.

[0018] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The limiting frame 3 includes a movable platform 10 located above the worktable 1. Guide blocks 11 are installed on both sides of the upper end of the movable platform 10. Limiting slides 12 are installed on both sides of the upper surface of the worktable 1. One end of the guide block 11 extends into the limiting slide 12. A square groove 13 is opened at the upper end of the movable platform 10. The moving direction of the movable platform 10 can be ensured by the guide block 11 and the limiting slide 12. The limiting block 4 is placed in the square groove 13, so that the limiting block 4 can move with the limiting frame 3.

[0019] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A fixing block 14 is installed on the upper surface of the worktable 1. The fixing block 14 and the moving table 10 are connected by a return spring 15. Under normal conditions, when the moving table 10 is stretched to one side and the limiting block 4 is placed on the moving table 10, the return spring 15 can be compressed. Then, the moving table 10 and the threaded rod are released. Under the elastic force of the return spring 15, the moving table 10 can move towards the detection sleeve 8. If the detection nut 9 does not correspond to the position of the detection sleeve 8, the detection nut 9 will fall outside the detection sleeve 8. When the detection sleeve 8 is rotated by the drive frame 7, the detection sleeve 8 can be rotated to the position corresponding to the detection nut 9. Then, under the elastic force of the return spring 15, the detection nut 9 can enter the detection sleeve 8, which makes it easier to rotate the detection nut 9.

[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3The limiting block 4 is a cuboid block. The lower end of the cuboid block can be placed in the square groove 13 and cannot rotate within the square groove 13. A nut holding groove 16 is opened on one side of the upper end of the cuboid block. The limiting nut 6 is placed in the nut holding groove 16 and cannot rotate, which makes it easy to connect the limiting nut 6 to the limiting block 4.

[0021] The limit nut 6 is hexagonal in shape and comes in various models. The limit nut 6 has the same external size but different thread hole sizes. Different models of limit nut 6 can be replaced according to different diameter threaded rods, which facilitates the inspection of threaded rods of various diameters.

[0022] Refer to the instruction manual appendix Figure 1 The drive frame 7 is a DC motor mounted on the workbench 1. The detection sleeve 8 is mounted on the rotating end of the DC motor. When the drive frame 7 drives the detection sleeve 8 to rotate but cannot make the detection nut 9 rotate, the DC motor will slip, thus preventing damage to the motor.

[0023] The testing nut 9 comes in various models. The testing nut 9 of various models has the same external size, but the size of the threaded hole inside the testing nut 9 is different. Different models of testing nut 9 can be replaced according to the threaded rod of different diameters, which makes it convenient to test threaded rods of various diameters.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
