Technical Field

[0001] The utility model relates to the field of building electromechanical engineering, in particular to an adjustable earthquake-resistant hanger for a cable bridge. Background Art

[0002] Seismic supports and hangers are a support system used to ensure that electromechanical equipment such as cable trays and pipelines can maintain stability and safety during natural disasters such as earthquakes. It combines the design principles of electromechanical equipment and building structures, and through reasonable support and fixing methods, reduces the impact of seismic forces on electromechanical equipment, preventing equipment damage and data loss.

[0003] The patent document with application number 202120281106.9 discloses an earthquake-resistant support and hanger for a cable tray, which belongs to the technical field of earthquake-resistant support and hanger.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0026] The utility model discloses an adjustable seismic hanger for a cable tray, which is mainly used in long-term use. Due to material aging, loose connections and other reasons, the maintenance and replacement process is relatively complicated and cumbersome, resulting in maintenance and management difficulties, increasing the risk of equipment failure and affecting the normal operation of the equipment.

[0027] Reference Figure 2 , Figure 3 and Figure 4 , an adjustable earthquake-resistant hanger for a cable tray, comprising an upper cross frame 1, a lower cross frame 2, a clamping rod 4 and a bracket 3, and also comprising:

[0028] Installation mechanism: The installation mechanism is arranged inside the bracket 3, and an assembly bin 13 is arranged inside the bracket 3. A circular hole is opened on the inner wall of one side of the assembly bin 13, and sockets are opened on the inner walls of both sides of the assembly bin 13. A connecting rod 16 is inserted into the circumferential inner wall of the circular hole, and the two ends of the connecting rod 16 are respectively connected to the disc 5 and the control block. Two limiting grooves are opened on the outer wall of one side of the control block, and a round rod 15 is installed on the inner wall of the limiting groove. One end of the round rod 15 is connected to a slider 14, and the slider 14 is slidably installed on the inner wall of the socket;

[0029] Adjustment mechanism: The adjustment mechanism is arranged inside the clamping rod 4.

[0030] Wherein, fixing grooves 12 are provided on the side walls at both ends of the lower cross frame 2, and the fixing grooves 12 are used in conjunction with the installation mechanism.

[0031] In the specific implementation process, the round rod 15 is controlled by rotating the disc 5 to push the slider 14 to move, so as to achieve a fixed connection between the bracket 3 and the lower cross frame 2. The various components of the hanger are easy to disassemble and replace. When one of the components is damaged, it can be disassembled separately. After disassembly, the seismic hanger can still be used temporarily to ensure the normal operation of the cable tray and the electromechanical equipment it carries, making maintenance and management more convenient.

[0032] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, an installation groove 8 and a slide groove 9 are opened on the outer wall of one side of the upper cross frame 1 and the lower cross frame 2, and the two ends of the clamping rod 4 are respectively slidably inserted into the interior of the upper cross frame 1 and the lower cross frame 2, and a slot 10 is opened at both ends of the lower cross frame 2. A card slot 11 is opened on the bottom inner wall of the slot 10, and a baffle 6 is installed inside the card slot 11.

[0033] The clamp rod 4 is slidably inserted into the upper cross frame 1 and the lower cross frame 2, making the installation process simpler and faster. During maintenance and repair, the various components do not affect each other and can be disassembled and replaced separately, which improves work efficiency. The setting of the card slot 11 and the baffle 6 can prevent safety hazards caused by loosening or falling off.

[0034] Reference Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In a preferred embodiment, the adjustment mechanism includes a ball 7, a support rod 18 and a positioning groove 20. An assembly groove 19 is opened on the top outer wall of the clamp rod 4. The support rod 18 is installed inside the assembly groove 19, and a spring is provided on the circumferential outer wall of the support rod 18. The ball 7 is fixed to one end of the support rod 18. The positioning grooves 20 are evenly distributed on the inner wall of the mounting groove 8 at the bottom of the upper cross frame 1. The diameter of the ball 7 is the same as the diameter of the positioning groove 20.

[0035] When installing the clamp rod 4, push the clamp rod 4, the ball 7 is forced to move downward, compressing the spring, and the ball 7 returns to the inside of the assembly groove 19. Push it to a position suitable for fixing the cable tray and release the clamp rod 4. The ball 7 cooperates with the positioning groove 20 to achieve positioning. The position of the clamp rod 4 can be quickly adjusted through the adjustment mechanism. The hanger can adapt to the installation requirements of cable trays of different sizes, thereby improving the versatility and adaptability of the hanger.

[0036] Reference Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, four symmetrically distributed rubber wheels 17 are installed on the bottom outer walls of the bases at both ends of the clamp rod 4, and the rubber wheels 17 are slidably installed on the bottom inner wall of the slide groove 9.

[0037] The design of the rubber wheel 17 makes the movement of the clamping rod 4 in the slide groove 9 smoother, reduces wear and noise between components, and also provides stable support for the clamping rod 4 to prevent the clamping rod 4 from shaking or deflecting during the adjustment process.

[0038] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the angle between the bracket 3 and the vertical direction is 45°. The design of the bracket 3 tilted at 45° enables it to better disperse and balance the force when bearing the weight of the cable tray and external force, thereby enhancing the stability of the entire hanger structure.

[0039] Working principle: When in use, first insert the clamp rod 4 into the inside of the upper cross bar and the lower cross bar, push it to the appropriate position to clamp the cable tray to the fixed column, then insert the bottom of the bracket 3 into the fixed groove 12, rotate the disc 5 and push the slider 14 into the fixed groove 12 to achieve fixed installation. The operation is simple. When one of the components is damaged, it can be disassembled separately without affecting the normal use of the hanger, reducing the difficulty of maintenance and overhaul.

[0040] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
