Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing, in particular to a cable fixing clamp used for power transmission and transformation construction. Background Art

[0002] Substation construction refers to the series of engineering operations performed during the construction, renovation, or maintenance of a substation. This includes substation site selection, site leveling, foundation construction, and the installation and commissioning of electrical equipment. During substation construction, cables often need to be laid in different areas within the substation, such as from the control room to the switchyard or from the transformer to the switchgear. Without cable clamps, cables can shift due to factors such as their own weight, contact from pedestrians, and wind, causing electrical failures. Using cable clamps prevents cable movement and ensures that the cables are securely positioned.

[0003] In the prior art, some cable fixing clamps usually use two clamp frames to clamp the cables with bolts, but the cable fixing clamp frames are usually designed and manufactured according to a certain range of cable specifications. When encountering cables of non-standard sizes, poor adaptation will occur, and the shape of the cable will also affect the use effect of the clamp frame, thereby making the cable adaptability low. In addition, in areas with strong earthquakes or strong winds, when the cable is subjected to huge external force impact, the clamp frame cannot fully buffer the stress generated by these external forces, which accelerates the damage to the cable outer sheath and internal structure and affects the service life of the cable. Therefore, in response to the above shortcomings, a cable fixing clamp for power transmission and transformation construction is proposed. Summary of the Invention

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology and propose a cable fixing clamp for power transmission and transformation construction, aiming to improve the problems in the existing technology that it cannot adapt to cables of different shapes and will accelerate the damage of the cable when it is impacted, thereby reducing the service life of the cable.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cable fixing clamp for power transmission and transformation construction, comprising two clamp frames, the bottom ends of the clamp frames are fixedly connected with an assembly component for installation, the inner walls of the adjacent sides of the two clamp frames are slidably connected with multiple adapter rods, the distant sides of the multiple adapter rods are fixedly connected with a baffle, the adjacent sides of the two clamp frames are provided with multiple accommodating holes, the inside of the accommodating holes is provided with a telescopic spring, the left and right sides of the clamp frames are fixedly connected with connecting blocks, and the adjacent sides of every two connecting blocks are rotatably connected with a rotating block.

[0006] Furthermore, the upper and lower sides of the rotating block are fixedly connected with screws, the outer side of the screw is provided with two strong springs, the upper and lower ends of the strong springs are fixedly connected with gaskets, and the outer side of the screw is threadedly connected with two nuts.

[0007] Furthermore, the assembly component includes two assembly blocks, the top of each assembly block is provided with two mounting holes, the internal threads of the mounting holes are connected with bolts, and the tops of the two assembly blocks are fixedly connected to the bottom of the wire clamp frame.

[0008] Furthermore, the outside of the baffle is slidably connected to the inside of the accommodating hole, and the material of the baffle is rubber.

[0009] Furthermore, one end of the telescopic spring is fixedly connected to one side of the interior of the accommodating hole, and the other end of the telescopic spring is fixedly connected to one side of the baffle.

[0010] Furthermore, the outer portion of the screw is threadedly connected to the interior of the connecting block, and the outer portion of the gasket is slidably connected to the exterior of the screw.

[0011] Furthermore, one side of one of the gaskets is fixedly connected to one side of the connecting block, and one side of the other gasket is in contact with one side of the nut.

[0012] Furthermore, the wire clamp frame is made of stainless steel, and the bottom end of the upper wire clamp frame is in contact with the top end of the lower wire clamp frame.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the present invention, after the cable is installed, multiple telescopic springs are used to drive the adapter rod to clamp and fix the cable. When the cable diameter is large or small, the telescopic spring will be compressed and stretched, and the adapter rod will adjust its position accordingly to adapt to the size of the cable, ensuring that the adapter rod can still effectively clamp the cable. The telescopic spring can play a buffering role. The impact force will compress the spring, thereby absorbing part of the energy, reducing the impact force directly transmitted to the cable, avoiding damage to the cable due to instantaneous excessive impact force, and improving the service life of the cable.

[0015] 2. In the present invention, when the rotating block is turned to make the upper and lower screws preliminarily tighten the wire clamp frame, a certain clamping force has been provided for the cable. On this basis, when the nut is turned, it drives the strong spring to apply force to the wire clamp frame, which can further increase the clamping force on the cable, ensuring that the cable is more firmly fixed in the wire clamp frame, preventing the cable from being displaced due to external force during operation, and ensuring the stability of the cable position.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 3 , the utility model provides an embodiment: a cable fixing clamp for power transmission and transformation construction, comprising two clamp frames 1. The clamp frame 1 is made of stainless steel, which has many advantages. Stainless steel has strong corrosion resistance and can maintain its own structure and performance stability in various harsh environments, thereby ensuring the long-term use of the cable fixing clamp. Moreover, stainless steel has sufficient strength to withstand the mechanical requirements required during the cable fixing process, ensuring that the cable is reliably fixed. The bottom end of the upper clamp frame 1 is in contact with the top of the bottom clamp frame 1. This design provides a basic structure for the subsequent clamping operation of the cable. The bottom end of the clamp frame 1 is fixedly connected to an assembly component for installation. The assembly component includes two assembly blocks 2. The assembly block 2 is an important connecting component, which plays a role in connecting the clamp frame 1 to the installation position. Two mounting holes 3 are provided at the top of the assembly block 2;

[0024] The mounting holes 3 are designed to facilitate installation operations via bolts 4. The size and shape of these mounting holes 3 precisely match the specifications of the bolts 4, ensuring that the bolts 4 can be smoothly threaded into the mounting holes 3. The top ends of the two assembly blocks 2 are firmly fixed to the bottom end of the wire clamp frame 1. This fixed connection ensures that the assembly components and the wire clamp frame 1 become a whole, and will not loosen or separate during installation and use. The inner walls of the adjacent sides of the two wire clamp frames 1 are slidably connected with multiple adapter rods 5, which are key components for achieving adaptive clamping of the cable. The multiple adapter rods 5 are fixedly connected to the far side with a baffle 6, which plays an important role in limiting and connecting. Multiple accommodating holes 7 are provided on the adjacent sides of the two wire clamp frames 1;

[0025] The outside of the baffle 6 is slidably connected to the inside of the receiving hole 7, and the baffle 6 is made of rubber. The baffle 6 made of rubber has good elasticity and flexibility. On the one hand, it can reduce friction and wear during the sliding fit with the receiving hole 7. On the other hand, it can play a buffering role through its own elastic deformation when subjected to external force. A telescopic spring 8 is provided inside the receiving hole 7. One end of the telescopic spring 8 is fixedly connected to one side of the inside of the receiving hole 7, and the other end is fixedly connected to one side of the baffle 6. The telescopic spring 8 provides power for adaptive adjustment for the adapter rod 5. When the cable is placed between the two wire clamp frames 1, the telescopic spring 8 can automatically adjust the position of the adapter rod 5 according to the diameter of the cable. The left and right sides of the wire clamp frame 1 are fixedly connected with connecting blocks 9. The adjacent side of each two connecting blocks 9 is rotatably connected with a rotating block 10. The connecting block 9 serves as an important connecting and supporting structure, ensuring that the rotating block 10 can be stably installed on the wire clamp frame 1.

[0026] Reference Figure 1 、 Figure 2 and Figure 4 , the upper and lower sides of the rotating block 10 are fixedly connected with a screw rod 11, and the external thread of the screw rod 11 is connected to the inside of the connecting block 9. This threaded connection method enables the screw rod 11 to perform precise linear movement inside the connecting block 9 when the rotating block 10 rotates. Two strong springs 12 are sleeved on the outside of the screw rod 11, and the upper and lower ends of the strong springs 12 are fixedly connected with gaskets 13, and the outside of the gasket 13 is slidably connected to the outside of the screw rod 11. The gasket 13 plays a role in evenly distributing pressure and reducing friction, ensuring that the strong spring 12 can smoothly transmit force during compression or extension. The external thread of the screw rod 11 is connected to two nuts 14, one side of which is fixedly connected to one side of the connecting block 9, and one side of the other gasket 13 is in contact with one side of the nut 14.

[0027] Working principle: When using the cable fixing clamp for power transmission and transformation construction, first place the cable between the two clamp frames 1. By rotating the rotating block 10, the rotating block 10 drives the screws 11 on the upper and lower sides to rotate. Since the external thread of the screw 11 is connected to the inside of the connecting block 9, the rotation of the screw 11 causes the screw 11 to move inside the connecting block 9, thereby bringing the two clamp frames 1 close to each other and initially clamping the cable.

[0028] Once the cable is in place, multiple telescopic springs 8 begin to function. One end of the telescopic spring 8 is fixed to one side of the receiving hole 7, and the other end is fixed to one side of the baffle 6. The baffle 6 is externally slidably connected to the receiving hole 7 and is fixedly connected to the adapter rod 5. When the cable diameter is large, the cable pushes the adapter rod 5, which drives the baffle 6 to slide within the receiving hole 7, compressing the telescopic spring 8 and adjusting the adapter rod 5 accordingly to accommodate the cable size. When the cable diameter is small, the telescopic spring 8 extends, pushing the baffle 6 and adapter rod 5 to move, ensuring that the adapter rod 5 can still effectively clamp the cable. Furthermore, when an external impact force acts on the cable, the impact force causes the cable to squeeze the adapter rod 5, which pushes the baffle 6 to compress the telescopic spring 8. The telescopic spring 8 absorbs some of the energy through its own compression, reducing the impact force directly transmitted to the cable and preventing damage to the cable due to excessive instantaneous impact force.

[0029] After initially clamping the cable with the rotating block 10 and screw 11, further tighten the nut 14. As the nut 14 rotates on the screw 11, the upper and lower ends of the strong spring 12 contact the connecting block 9 and the nut 14 respectively through the gasket 13. The rotation of the nut 14 causes the nut 14 to push the gasket 13 on the side of the contact with it. The gasket 13 squeezes the strong spring 12. The compressed strong spring 12 applies force to the wire clamp frame 1, further increasing the clamping force on the cable, ensuring that the cable is more firmly fixed in the wire clamp frame 1, preventing the cable from being displaced by external forces such as vibration and wind during operation, and ensuring the stable position of the cable.

[0030] Meanwhile, the assembly assembly, fixedly connected to the bottom of the cable clamp frame 1, is used to install the cable clamp in the appropriate position. The assembly block 2 in the assembly assembly has a mounting hole 3 at its top. Bolts 4 are threaded into the mounting hole 3 to secure the assembly block 2 in place, completing the installation of the cable clamp.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
