Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower lead wire clamp technology, specifically to a power installation lead wire clamp. Background Technology
[0002] Tower downlead clamps are primarily used to secure ADSS (non-metallic optical cable) and OPGW (optical fiber composite overhead ground wire) optical cables to their downlead positions on towers, preventing damage caused by wind swaying and friction with the tower or other objects. By firmly fixing the optical cable to a designated location on the tower (such as tower legs or the tower frame), they prevent the cable from swaying under wind force, reduce direct friction with tower structural components, and lower the risk of wear.
[0003] The prior art, disclosed in publication number CN222839043U, discloses a power installation lead clamp. However, this clamp requires drilling holes in the power tower or pole frame before installation, causing damage to the tower or pole frame and increasing installation difficulty. Furthermore, as shown in Figure 4, the existing product lacks a standard threaded fastening installation during cable clamping, easily leading to excessive clamping stress that damages the cable's outer protective layer and increases the risk of lead leakage. Additionally, the existing product's clamping structure is a single-sided abutment fixation, which easily causes deformation of the clamping plate on the power tower, resulting in poor clamping stability. With repeated disassembly and installation, the lead clamp is prone to instability and falling off.
[0004] Therefore, a power installation lead clamp is needed. Utility Model Content
[0005] In view of the problems existing in the prior art, the present invention provides a power installation lead clamp, which aims to improve and solve the technical problems mentioned above.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a power installation lead clamp, comprising a power tower, with several bent clamps evenly distributed on one side of the power tower and several fixed clamps evenly distributed on the inner side. The bent and fixed clamps are installed on the side away from the power tower surface using bolts and nuts to clamp them onto the power tower. The side of the fixed clamps away from the power tower is designated as a cable clamp, with bolt rods distributed on its surface. Cable grooves are formed on the surface of the cable clamp between the bolt rods. A second cable clamp is installed on the upper sleeve. The side of the second cable clamp facing the first cable clamp is set as a second cable groove. The lead cable is clamped between the first cable groove and the second cable groove. A bolt rod passes through the second cable clamp and is fitted with a buffer spring. A washer is set at the end of the buffer spring away from the second cable clamp. The washer is fitted with the bolt rod. The side of the washer away from the buffer spring is set as a fastening nut. The fastening nut is threadedly installed with the bolt rod. The fastening nut is tightened by the thread of the fastening nut to compress the buffer spring and ensure that the second cable clamp and the first cable clamp cooperate to clamp the lead cable.
[0007] Preferably, the side of the fixing plate away from the power tower is provided with bolt rod two, which passes through the bent clamp plate and is fastened with nuts.
[0008] Preferably, a soft protective pad is provided inside the cable groove and the cable recess.
[0009] Preferably, cable groove one and cable groove two are arranged with the same center structure, and the groove depth of cable groove one is greater than the groove depth of cable groove two.
[0010] Preferably, the bending clamp is arranged in a "Z" shape, and the bending part of the bending clamp is arranged to abut against the power tower.
[0011] In summary, this utility model provides a power installation lead wire clamp. This utility model patent describes a mechanism where a pair of fastening nuts and a pair of washers compress a buffer spring, causing the second cable clamp to move towards the first cable clamp. As the fastening nuts are tightened, the first and second cable clamps hold the lead cable. The buffer springs provide stress buffering during the cable clamping process. Once the lead cable is clamped and fixed, tightening the first fastening nut stops, completing the installation of each lead wire clamp. This solves the problem of excessive clamping force and lack of buffering in existing lead wire clamps, which can damage the cable's outer protective layer. This invention provides both cable clamping protection and a stable installation clamp. The cable clamp plate 1 and cable clamp plate 2 are used to clamp and fix the lead wire, which improves the efficiency of the lead wire wiring and fixing construction work and saves time and effort on site. The cable groove 1 and cable groove 2 are set with the same center structure, and the groove depth of cable groove 1 is greater than the groove depth of cable groove 2. This invention enables the bending clamp and the fixing clamp to be used together to clamp and install on the power tower, solving the problem of deformation during the clamping process of existing lead wire clamping tools. Repeated disassembly and installation can easily cause the clamp to deform and fall off. The clamping and fixing of this patented clamp can effectively solve the deformation problem and maintain the clamping stability. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings.
[0014] like Figures 1 to 3 As shown: This utility model relates to a power installation lead wire clamp, providing a method for installing lead wire clamps without drilling holes, and enabling rapid installation of the lead wire clamp and its gripping, thus preventing damage to towers or pole-mounted cable racks by drilling holes. Furthermore, to avoid damage to the outer protective sleeve of the lead cable during clamping and to prevent deformation during installation, this patent employs the following technical method: The system includes a power tower 1. Several bent clamps 2 are evenly distributed on one side of the power tower 1, and several fixed clamps 3 are evenly distributed on the inner side. The bent clamps 2 and fixed clamps 3 are installed on the side away from the surface of the power tower 1 using bolts and nuts to clamp them onto the power tower 1. The side of the fixed clamps 3 away from the power tower 1 is designated as a cable clamp 4. Bolt rods 5 are distributed on the surface of the cable clamp 4. Cable grooves 6 are formed on the surface of the cable clamp 4 between the bolt rods 5. Cable clamps 7 are fitted onto the bolt rods 5, with the cable clamps 7 facing the cable clamps 1. One side of 4 is set as cable groove 2 11. The lead cable clamp is installed between cable groove 1 6 and cable groove 2 11. Bolt rod 1 5 passes through cable clamp 2 7 and is fitted with buffer spring 12. The end of buffer spring 12 away from cable clamp 2 7 is in contact with washer 13. Washer 1 13 is fitted with bolt rod 1 5. The side of washer 13 away from buffer spring 12 is set as fastening nut 14. Fastening nut 14 is threaded with bolt rod 1 5. The thread of fastening nut 14 is tightened to compress buffer spring 12 and ensure that cable clamp 2 7 and cable clamp 4 cooperate to clamp the lead cable.
[0015] The specific usage is as follows: Several lead wire clamps are distributed on the power tower 1 to ensure that the lead wires are neatly laid out on the power tower 1, avoiding swaying under wind force, reducing direct friction with the tower structure, and lowering the risk of wear; on one side of the power tower 1, a fixed clamp 3 and a bent clamp 2 are used to clamp and install the lead wire clamps on the power tower 1, achieving drilling-free installation; a cable clamp 4 is fixedly installed on one side of the fixed clamp 3. The thickness of the cable clamp 4 is larger than that of the cable clamp 7, so that the depth of the cable groove 6 on the cable clamp 4 is larger than that of the cable groove 11. When clamping and installing the lead wire, it can be pre-clamped into the deeper cable groove 6, and then clamped by the cable clamp 7 and the cable clamp 4 to complete the wiring and fixing of the lead wire; Bolt rods 5 are distributed on both sides of cable clamp 4, and bolt rods 5 penetrate cable clamp 7. During the clamping process, the fastening nut 14 is threaded onto the bolt rod 5, causing the fastening nut 14 to press against the washer 13, which in turn causes the buffer spring 12 to push the cable clamp 7 towards the cable clamp 4. As the fastening nut 14 is threadedly tightened, cable clamp 4 and cable clamp 7 clamp the lead cable. The buffer spring 12 provides stress buffering during the clamping process of the lead cable. After the lead cable is clamped and fixed, the fastening nut 14 is stopped, completing the installation of each lead clamping tool. This solves the problem of excessive clamping force and lack of buffering effect in existing lead clamp products, which can damage the outer protective layer of the cable. It achieves the protection of the cable clamp and the stabilization of the installation clamp.
[0016] In at least one embodiment, the fixing clamp 3 and the bending clamp 2 are fixedly installed by setting a bolt rod 15 on the side of the fixing clamp 3 away from the power tower 1. The bolt rod 15 passes through the bending clamp 2 and is fastened by a nut, so that the fixing clamp 3 and the bending clamp 2 cooperate to clamp and fix it on the power tower 1.
[0017] In at least one embodiment, to further protect the lead cable, a soft protective pad 16 is provided inside the cable groove 6.
[0018] In at least one embodiment, in order to achieve the clamping of the lead cable inside the deeper cable groove 11, the cable clamp 14 and cable clamp 27 are used to clamp and fix the lead cable, thereby improving the efficiency of the lead cable wiring and fixing construction work and saving time and effort on site. The cable groove 11 and cable groove 21 are set as concentric structures, and the groove depth of the cable groove 16 is greater than the groove depth of the cable groove 21.
[0019] In at least one embodiment, the bending clamp 2 is arranged in a "Z" shape, with the bent part of the bending clamp 2 abutting against the power tower 1. The bending clamp 2 and the fixed clamp 3 are fixed with nuts, so that the bending clamp 2 and the fixed clamp 3 can be clamped and installed on the power tower 1. This solves the problem of deformation during the clamping process of existing lead wire clamping tools. After repeated disassembly and installation, the clamp is prone to deformation and may fall off. The clamping and fixing of this patent can effectively solve the deformation problem and maintain the technical function of clamping stability.
[0020] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
