Description

Technical Field

[0001] This utility model belongs to the field of power transmission and transformation engineering technology, and in particular relates to a cable fixing bracket for power transmission and transformation engineering. Background Technology

[0002] Power transmission and transformation engineering is a general term for the construction of power transmission lines and the installation of transformers. The higher the voltage level of power transmission and transformation engineering, the greater the amount of electricity transmitted and the longer the transmission distance. In the field of power transmission and transformation engineering, cable fixing is an extremely important task.

[0003] Traditional cable fixing devices often have many shortcomings: 1. Many fixing devices only use simple clamping structures and lack flexible adjustment mechanisms, making it impossible to make adaptive adjustments according to different cable diameters; 2. When fixing cables, a lot of time is required to install flange rings and bolts. If the cable needs to be replaced later, the disassembly and installation steps must be repeated. This undoubtedly greatly increases the labor intensity of workers and the time cost, seriously affecting the efficiency of cable laying and other work in the entire power transmission and transformation project. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable fixing bracket for power transmission and transformation projects, and the technical solution adopted is as follows:

[0005] A cable fixing bracket for power transmission and transformation projects includes a mounting frame, a support plate on the outer side of the mounting frame, a pressure plate above the support plate, an arc-shaped slot below the pressure plate, a push rod on one side of the slot, the lower end of the push rod passing through the support plate; an upper cover box is installed on one side of the mounting frame and above the support plate, and a spring in contact with the pressure plate is provided inside the upper cover box.

[0006] Furthermore, a rubber sheet is covered on the upper surface of the support plate, and multiple raised particles are provided on the upper surface of the rubber sheet to enhance the friction when it comes into contact with the cable and prevent the cable from slipping.

[0007] Furthermore, a buffer pad is provided in the slot of the arc-shaped structure below the pressure plate for contact with the cable, so as to effectively buffer the pressure of the pressure plate on the cable and reduce the possible wear on the cable.

[0008] Furthermore, a reinforcing plate is provided at the lower angle between the support plate and the mounting frame, and reinforcing ribs are provided on the outside of the reinforcing plate, which can enhance the stability and load-bearing capacity of the support plate.

[0009] Furthermore, the inside of the upper cover box is provided with a groove that matches the size of the pressure plate. In conjunction with the square push rod, it can ensure that the pressure plate rises and falls smoothly.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention utilizes a spring to allow the pressure plate to move downwards and tightly press the cable. Combined with the raised particles on the upper surface of the rubber plate, it effectively prevents the cable from slipping. At the same time, the movable design of the pressure plate can accommodate cables of different diameters, ensuring a good pressing effect on cables of various specifications.

[0012] This utility model has a specific groove inside the top cover box, the size of which is perfectly matched with the size of the pressure plate. When the cable fixing operation is performed, the pressure plate will rise and fall accordingly in the groove as the spring expands and contracts. In conjunction with the square push rod, the pressure plate can be moved smoothly.

[0013] This invention eliminates the need for complex adjustment steps when placing cables. Simply push the push rod up, place the cable on the rubber plate, and then release the push rod. The pressure plate will automatically press down to secure the cable due to the automatic action of the spring. If cable replacement is required later, it can also be easily done, greatly saving manpower and time costs and making it convenient for workers to quickly complete cable fixing work in power transmission and transformation projects.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As attached Figure 1-3 As shown.

[0021] A cable fixing bracket for power transmission and transformation projects includes a mounting frame 1 fixed to a wall or pole, an outwardly extending support plate 11 on the outside of the mounting frame 1, a rubber plate 12 covering the upper surface of the support plate 11, a pressure plate 2 above the support plate 11, an arc-shaped slot below the pressure plate 2, a push rod 21 at the lower end of the pressure plate 2 and on one side of the slot, the lower end of the push rod 21 passing through the support plate 11; an upper cover box 3 is installed on one side of the mounting frame 1 and above the support plate 11, and a spring 5 for pressing down the pressure plate 2 is provided inside the upper cover box 3.

[0022] Based on the above structure, under the action of the spring 5, the pressure plate 2 can tightly press the cable placed above the rubber plate 12. The upper surface of the rubber plate 12 is provided with multiple protruding particles, which cooperate with the arc-shaped groove of the pressure plate 2 to prevent the cable from sliding and ensure the cable's fixed stability.

[0023] A buffer pad is provided at the connection between the pressure plate 2 and the cable. The buffer pad is made of soft material, which can effectively reduce the wear of the cable by the pressure plate 2. Since the pressure plate 2 can move down under the action of the spring 5, it can adapt to cables of different diameters and ensure its clamping effect.

[0024] Furthermore, a triangular reinforcing plate 4 is provided at the lower angle between the support plate 11 and the mounting bracket 1, and a reinforcing rib 41 is provided on the outer side of the reinforcing plate 4, as shown in the attached figure. Figure 2 As shown, the reinforcing rib 41 has a square structure, which can enhance the load-bearing capacity of the support plate 11 and prevent it from deforming.

[0025] The upper cover box 3 has a groove inside that matches the size of the pressure plate 2. The spring 5 is located inside the groove. The groove can guide the pressure plate 2. In conjunction with the square push rod 21, it can ensure the smooth lifting and lowering of the pressure plate 2.

[0026] The procedure for using this device is as follows: First, select a suitable location and use the mounting bracket 1 to securely install the cable fixing bracket on the wall or pole.

[0027] As shown in the attached figure, the mounting bracket 1 is a flat plate type, suitable for installation on flat structures; if it needs to be installed on curved structures, an arc-shaped mounting bracket can be selected to ensure that it fits tightly with the curved structure; during installation, pay attention to ensure that the mounting bracket 1 is firmly connected to the support surface and that the support plate 11 is kept horizontal.

[0028] After the mounting bracket 1 is fixed, the pressure plate 2 rises by pushing the push rod 21, leaving enough space to facilitate the placement of the cable on the surface of the rubber plate 12 on the support plate 11. During placement, the cable should be positioned in the middle of the support plate 11 as much as possible.

[0029] After the cable is placed, release the push rod 21. Under the elastic force of the spring 5, the pressure plate 2 will automatically press down. The arc-shaped groove under the pressure plate 2 and the raised particles on the rubber plate 12 will cooperate to firmly fix the cable and prevent the cable from slipping.

[0030] During use, regularly check the condition of each component of the bracket, check whether the spring 5 is faulty or deformed, check the wear of the rubber plate 12, and check whether the connection parts of the mounting bracket 1, support plate 11, etc. are loose.

[0031] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
