Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, and in particular to a heavy-duty hanger for cable trays. Background Technology
[0002] To withstand natural disasters and improve the operational safety of electromechanical systems, it is necessary to install seismic-resistant supports for the pipelines of electromechanical systems. Electromechanical systems contain a large number of cables, and most of the cables used in electromechanical systems on the market are installed and placed in cable trays. Cable trays are divided into trough type, tray type, ladder type, and mesh type structures, and are composed of supports, brackets and installation accessories.
[0003] Chinese patent application CN202320571741.X discloses a support structure for cable trays, including a horizontally arranged hanging plate. The top of the hanging plate is connected to a cable tray via a rubber plate. The top of the hanging plate is connected to an installation mechanism via symmetrically arranged hanging rods. The hanging rods are connected to symmetrically arranged clamping plates via a clamping mechanism. In use, this utility model includes a horizontally arranged hanging plate. Its key feature is that the top of the hanging plate is connected to a cable tray via a rubber plate, and the top of the hanging plate is connected to an installation mechanism via symmetrically arranged hanging rods. The hanging rods are connected to symmetrically arranged clamping plates via a clamping mechanism. After the cable tray is placed on the surface of the hanging plate, the adjusting plate can drive the adjusting rod to rotate. The adjusting rod will cause the two clamping plates to move closer together. The two clamping plates moving closer together can clamp and fix the cable tray, allowing the cable tray to be stably placed on the hanging plate without shifting.
[0004] However, existing cable trays still have some defects. Their structure is simple and their seismic performance is poor, resulting in incomplete shock absorption. Consequently, the seismic performance of the cable trays is poor, leading to cable breakage. Utility Model Content

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figures 1 to 6As shown, a heavy-duty hanger for cable trays includes a support rod 1, a crossbar 2 connected between the support rods 1, a switch mechanism 4 installed at both ends of the crossbar 2, a connecting rod 3 sleeved on the support rod 1, a fixing plate 5 installed at the bottom end of the connecting rod 3, a mounting bracket 6 sleeved on the fixing plate 5, a buffer mechanism 7 installed on the mounting bracket 6, a rectangular mounting hole 9 opened on the mounting bracket 6, a fixing bracket 8 slidably connected to the rectangular mounting hole 9, and auxiliary mechanisms 10 installed on both sides of the support rod 1.
[0028] The buffer mechanism 7 includes an upper limit seat 701 fixedly installed on the mounting frame 6, a second limit seat 702 installed through the fixing plate 5 at the top of the mounting frame 6, and a buffer spring 703 sleeved on the mounting frame 6. The two ends of the buffer spring 703 are fixedly connected to the bottom end of the second limit seat 702 and the fixing plate 5, respectively.
[0029] With the above solution, when the cable tray is subjected to impact, the buffer spring 703 absorbs the vibration energy through elastic deformation, effectively reducing the destructive impact of the instantaneous impact force on the cable tray. The limit seat 1 701 and limit seat 2 702 work together to limit the excessive compression of the buffer spring 703, preventing the cable tray from shifting or overturning under severe vibration, and ensuring structural stability. The elastic coefficient of the buffer spring 703 and the distance between the limit seat 1 701 and the limit seat 2 702 are precisely designed to ensure that elastic buffering is the main function under normal working conditions, while rigid limiting provides protection under extreme working conditions.
[0030] The auxiliary mechanism 10 includes a pair of hinge seats 1001 installed at both ends of the support rod 1. A movable rod 1002 is rotatably connected to the hinge seat 1001. A fixed seat 1003 is rotatably connected to one end of the movable rod 1002. A fixing hole 1004 is provided on the fixed seat 1003.
[0031] Through the above solution, the hinge structure of the hinge seat 1001, the movable rod 1002 and the fixed seat 1003 can flexibly adjust the support angle according to the installation environment and provide multi-directional auxiliary support force. Under complex working conditions, the auxiliary mechanism 10 can distribute the single point of force to multiple support points, enhance the hanger's resistance to lateral impact, avoid structural deformation or failure caused by single point of force, and ensure the stability of the cable tray.
[0032] The switching mechanism 4 includes a drive chamber 401 at both ends of the crossbar 2. A guide rod 402 is connected to the inner wall of the drive chamber 401. A push plate 403 is sleeved on the guide rod 402. A switch rod 404 is installed at one end of the push plate 403. A return spring 405 is sleeved on the guide rod 402. A rectangular slide groove 406 is opened at the top of the drive chamber 401. The push plate 403 is slidably connected to the rectangular slide groove 406.
[0033] Through the above scheme, the linkage design of the switch mechanism 4 and the adjustment hole 301 allows the insertion operation of the connecting rod 3 and the crossbar 2 to be completed by simply pushing the push plate 403. With the automatic reset function of the reset spring 405, the height of the hanger can be infinitely adjusted.
[0034] The fixing bracket 8 has a pair of positioning holes 801. The fixing bracket 8 is connected to an anti-slip pad 802. A fixing screw 803 is fitted on the positioning hole 801. The fixing screw 803 passes through the positioning hole 801 and a ring washer 804 is fitted on the rectangular mounting hole 9. The bottom end of the fixing screw 803 is threadedly connected to a fixing nut 805.
[0035] With the above scheme, the mounting bracket 8 is slidably connected to the fixing screw 803 through the rectangular mounting hole 9, which can flexibly adjust the installation position and adapt to different specifications of cable trays. The elastic deformation of the annular pad 804 provides pre-tightening force to prevent the fixing screw 803 from loosening. The high friction coefficient material further enhances the fit between the mounting bracket 8 and the cable tray, reducing the risk of displacement during operation.
[0036] An adjustment hole 301 is provided on the inner side of the connecting rod 3, and the switch rod 404 is inserted and connected to the adjustment hole 301.
[0037] The top of the support rod 1 is connected to a mounting plate 101, and the mounting plate 101 has a mounting hole 102.
[0038] With the above scheme, the support rod 1 serves as the main support structure and is fixed by the top mounting plate 101 and mounting holes 102. The crossbar 2 is connected between the support rods 1 to form a stable frame structure.
[0039] The working principle of this utility model patent is as follows: First, the mounting plate 101 at the top of the support rod 1 is attached to the mounting surface and fixed with expansion bolts through the mounting holes 102, ensuring that the support rod 1 is perpendicular to the mounting surface. Depending on the installation environment, the rotation angle between the movable rod 1002 and the hinge seat 1001 is adjusted. The fixed seat 1003 is then attached to the wall or structure and fixed with expansion bolts through the fixing holes 1004, ensuring that the auxiliary mechanism 10 provides stable support. Finally, the fixing frame 8 is slid along the rectangular mounting holes 9 of the mounting frame 6 to the target position. Ensure that the positioning hole 801 of the fixing bracket 8 is aligned with the mounting hole of the mounting bracket 6. Place the cable tray on the anti-slip pad 802 of the fixing bracket 8, insert the fixing screw 803, put on the annular washer 804, and lock it with the fixing nut 805. When the cable tray is subjected to impact force, the mounting bracket 6 moves downward and compresses the buffer spring 703. The impact energy is absorbed by the elastic deformation of the spring.
[0040] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
