Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power engineering technology, specifically relating to a seismic-resistant mounting bracket for power engineering. Background Technology
[0002] Electrical engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering projects that use electricity as a power source and energy source in various fields. It can also be understood as power transmission and transformation expansion projects. During the construction of electrical engineering wiring, mounting frames are often used to support cables, making the cables more stable and neat.
[0003] Existing mounting brackets do not have earthquake resistance. When the mounting brackets are subjected to vibration due to external factors, they are prone to loosening or falling off, which can damage the cables on the mounting brackets and cause safety hazards such as short circuits and power outages. In severe cases, it may cause fires or other safety accidents. Therefore, we provide an earthquake-resistant mounting bracket for power engineering. Utility Model Content
[0004] The purpose of this utility model is to provide a seismic-resistant mounting bracket for power engineering to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant mounting bracket for power engineering, comprising a mounting plate and a lower pressure plate. Spring shock absorbers are fixedly connected to all four sides of the top of the mounting plate. A top plate is fixedly connected to the top of each spring shock absorber. A positioning plate is fixedly connected to the top of the top plate. First movable shafts are fixedly connected to both sides of the bottom of the top plate. A cavity is formed in the top of the mounting plate, and a sliding rod is fixedly connected inside the cavity. Sliding sleeves are slidably connected to both sides of the sliding rod surface. A second movable shaft is fixedly connected to the top of the sliding sleeve. The second movable shaft and the first movable shaft are hinged together by a movable rod. A composite spring is wound around one side of the sliding sleeve and on the surface of the sliding rod.
[0006] By adopting the above scheme, the vibration force is transmitted to the movable rod through the first movable shaft, then to the second movable shaft through the movable rod, then to the sliding sleeve through the second movable shaft, and finally to the composite spring through the sliding sleeve. Utilizing the elastic properties of the composite spring, the composite spring will deform, thereby canceling out the lateral vibration force and achieving the purpose of multiple shock absorption, which greatly improves the anti-vibration effect of the device during use.
[0007] As a preferred embodiment of a seismic-resistant installation frame for power engineering, the front and rear ends of both sides of the positioning plate and the lower pressure plate are fixedly connected with connecting blocks, and the two connecting blocks are fixedly connected by fastening bolts.
[0008] By using the above solution, the cable passing between the positioning plate and the pressure plate is pressed down and fixed to prevent the cable from becoming loose.
[0009] As a preferred embodiment of a seismic-resistant mounting bracket for power engineering, mounting blocks are fixedly connected to both sides of the front and back surfaces of the mounting plate, and mounting bolts are threaded onto the mounting blocks.
[0010] By adopting the above solution and using the mounting bolts, the mounting plate can be quickly installed in the designated position, which greatly improves the installation efficiency.
[0011] As a preferred embodiment of a seismic-resistant mounting bracket for power engineering, a sliding groove is provided at the bottom of the cavity of the mounting plate, and a slider is fixedly connected to the bottom of the sliding sleeve, with the bottom of the slider slidably connected to the inner wall of the sliding groove.
[0012] By adopting the above solution, the slider is limited by the setting of the slide groove, which assists the slide sleeve in moving and improves the smoothness of the slide sleeve movement.
[0013] As a preferred embodiment of a seismic-resistant mounting bracket for power engineering, the bottom of the lower pressure plate is bonded with a protective pad, and the anti-slip pad is evenly distributed on the bottom of the lower pressure plate.
[0014] By adopting the above solution and adding a protective pad, the friction between the bottom of the pressure plate and the cable contact surface is increased, further improving the stability after pressing.
[0015] As a preferred embodiment of a seismic-resistant mounting bracket for power engineering, the spring damper includes a spring element and a damping element, and the spring element and the damping element are respectively disposed on the surface and inside of the spring damper.
[0016] Using the above scheme, when the device is subjected to vibration, the spring element on the surface of the spring damper will undergo elastic deformation to absorb vibration energy. At the same time, the damping element inside the spring damper will consume vibration energy and reduce vibration amplitude. Through the combined use of the spring element and the damping element, the vertical vibration force can be effectively eliminated.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model transmits the vibration force to the movable rod through the first movable shaft, then to the second movable shaft through the movable rod, then to the sliding sleeve through the second movable shaft, and finally to the composite spring through the sliding sleeve. Utilizing the elastic properties of the composite spring, the composite spring will deform, thereby canceling out the lateral vibration force.

[0024] Please see Figure 1-3 A seismic-resistant mounting bracket for power engineering includes a mounting plate 1 and a lower pressure plate 5. A protective pad is adhered to the bottom of the lower pressure plate 5, and anti-slip pads are evenly distributed on the bottom of the lower pressure plate 5. The protective pads increase the friction between the bottom of the lower pressure plate 5 and the cable contact surface, further improving the stability after pressing. Spring shock absorbers 2 are fixedly connected to all four sides of the top of the mounting plate 1. Figure 1As shown, the spring damper 2 includes a spring element and a damping element, which are respectively disposed on the surface and inside of the spring damper 2. When the device is subjected to vibration, the spring element on the surface of the spring damper 2 undergoes elastic deformation to absorb vibration energy, while the damping element inside the spring damper 2 consumes vibration energy and reduces vibration amplitude. Through the combined use of the spring element and the damping element, the vertical vibration force can be effectively eliminated. A top plate 3 is fixedly connected to the top of the spring damper 2, and a positioning plate 4 is fixedly connected to the top of the top plate 3. First movable shafts 8 are fixedly connected to both sides of the bottom of the top plate 3. A cavity is opened at the top of the mounting plate 1, and a sliding rod 9 is fixedly connected inside the cavity. Both sides of the device are slidably connected to a sliding sleeve 10. The top of the sliding sleeve 10 is fixedly connected to a second movable shaft 11. The second movable shaft 11 and the first movable shaft 8 are hinged together by a movable rod 12. A composite spring 13 is wound around one side of the sliding sleeve 10 and on the surface of the sliding rod 9. The vibration force is transmitted to the movable rod 12 through the first movable shaft 8, to the second movable shaft 11 through the movable rod 12, to the sliding sleeve 10 through the second movable shaft 11, and to the composite spring 13 through the sliding sleeve 10. Utilizing the elastic properties of the composite spring 13, the composite spring 13 will deform, thereby canceling the lateral vibration force and achieving the purpose of multiple shock absorption, which greatly improves the anti-vibration effect of the device during use.
[0025] See Figure 1 As shown, connecting blocks 6 are fixedly connected to the front and rear ends of both sides of the positioning plate 4 and the lower pressure plate 5, and the two connecting blocks 6 are fixedly connected by fastening bolts 7. The positioning plate 4 and the lower pressure plate 5 are used to press down and fix the cable passing between them, preventing the cable from becoming loose. Figure 1 As shown, mounting blocks are fixedly connected to both sides of the front and back surfaces of mounting plate 1, and mounting bolts are threaded onto the mounting blocks. The use of mounting bolts facilitates the quick installation of mounting plate 1 in designated positions, greatly improving installation efficiency. Figure 3 As shown, a sliding groove is provided at the bottom of the cavity of the mounting plate 1. A slider is fixedly connected to the bottom of the sliding sleeve 10, and the bottom of the slider is slidably connected to the inner wall of the sliding groove. The sliding groove limits the slider and assists the sliding sleeve 10 in moving, thus improving the smoothness of the sliding sleeve 10 when it moves.
[0026] In use, first place the mounting plate 1 in the designated position, and connect the mounting bolts from the mounting block to the external mechanism using an external device to achieve rapid installation. After installation, pass multiple cables through the positioning plate 4 in sequence, and snap the lower pressure plate 5 onto the top of the positioning plate 4 to press and fix the cables passing through the positioning plate 4. At the same time, fix the positioning plate 4 and the lower pressure plate 5 with the fastening bolts 7, further improving the stability of the positioning plate 4 and the lower pressure plate 5 during use. Then, during the use of the device, when the device is subjected to vibration or impact, the spring element on the surface of the spring shock absorber 2 will undergo elastic deformation to absorb vibration energy. The damping element inside the spring damper 2 consumes vibration energy and reduces vibration amplitude. Through the combined use of the spring element and the damping element, the vertical vibration force can be effectively eliminated. In this process, the vibration force is transmitted to the movable rod 12 through the first movable shaft 8, to the second movable shaft 11 through the movable rod 12, to the sliding sleeve 10 through the second movable shaft 11, and to the composite spring 13 through the sliding sleeve 10. Utilizing the elastic properties of the composite spring 13, the composite spring 13 will deform, thereby offsetting the lateral vibration force and achieving the purpose of multiple shock absorption, which greatly improves the anti-vibration effect of the device during use.
