Abstract
Description
Technical Field
[0001] This application relates to the field of overhead insulated cable technology, and in particular to a flexible overhead insulated cable harness. Background Technology
[0002] Currently, overhead insulated cables, as overhead conductors with insulation layers and protective outer sheaths, are manufactured using a cross-linked cable-like process, possessing both conductivity and outdoor weather resistance. However, in actual operation, under the influence of wind loads and mechanical vibrations, relative displacement can easily occur between cables, leading to long-term friction damage to the insulation layer and even causing phase-to-phase short circuit faults. Therefore, it is necessary to use separator clamps to achieve orderly fixation and spaced protection of the cables.
[0003] Existing cable clamps mainly use grooves to position and hold cables. These clamps are typically straight or Y-shaped. Straight clamps are suitable for horizontally arranged two-core or four-core cables, achieving parallel fixation through equidistant grooves distributed in a straight line. Y-shaped clamps are designed for three-core cables, forming a stable triangular arrangement structure with grooves arranged in an equilateral triangle. Both types of clamps use a rigid frame to constrain the cables to the preset slots and connect to the crossarm of the tower via bolts or clips to achieve mechanical constraint on the cable spacing.
[0004] The existing technical solutions mentioned above have the following drawbacks: When increasing or decreasing the number of overhead insulated cables, it is necessary to change the arrangement of the overhead insulated cables. Therefore, it is necessary to disassemble the separating clamps and replace them with the corresponding shape of separating clamps. In high-altitude working environments, it is necessary to remove the original fixing parts and replace the clamp models in sequence, which is cumbersome and inefficient. Utility Model Content
[0005] This application provides a flexible overhead insulated cable harness to adapt to the interval installation of different numbers of overhead insulated cable harnesses and improve installation efficiency.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:
[0007] A flexible overhead insulated cable harness includes an installation component and a fixing component that can form a complete cylinder. A first mounting cylinder and a second mounting cylinder are fixedly connected to opposite sides of the outer peripheral wall of the installation component. The first and second mounting cylinders are staggered on both sides of the installation component. A hinge rod is slidably disposed inside the first mounting cylinder. A rotating column is coaxially rotatably disposed on the end face of the hinge rod near the second mounting cylinder. A second sliding block is disposed on the peripheral wall of the rotating column. A second sliding groove communicating with both end faces is formed on the inner wall of the second mounting cylinder along its axial direction. The second sliding block is adapted to the second sliding groove and can slide within the second sliding groove. A fixing groove is formed on the end face of the second mounting cylinder opposite to the first mounting cylinder. The second sliding block is adapted to the fixing groove and can be inserted into the fixing groove.
[0008] By adopting the above technical solution, and by setting up mounting components, fixing components, a first mounting cylinder, a second mounting cylinder, a hinge rod, a rotating column, and a second sliding block, when connecting two mounting components, the rotating column and hinge rod of one mounting component are inserted into the second mounting cylinder of the other mounting component, the second sliding block slides in the second sliding groove, the opposite end faces of the first and second mounting cylinders abut against each other, and the two side walls of the two mounting components are flush with each other. By rotating the rotating column, the second sliding block is inserted into the fixing groove, and the two mounting components are hinged together. This allows multiple mounting components to adjust their angles by adding or removing mounting components when adding or removing overhead insulated cables, thereby adapting to the interval installation of different numbers of overhead insulated cable bundles, reducing the tedious operation of changing clamps during high-altitude operations, and improving installation efficiency.
[0009] Optionally, the end of the hinge rod away from the second mounting cylinder is coaxially fixed with a second annular thickened portion, and a spring is provided between the second thickened portion and the first mounting cylinder, with the two ends of the spring fixed to the surfaces of the first and second mounting cylinders respectively.
[0010] By adopting the above technical solution, and by setting the second thickened part and the spring, the elastic force of the spring can provide buffer when the hinge rod slides. At the same time, after the rotating column is adjusted to a suitable position, the elastic force of the spring can push the second thickened part to keep the hinge rod stable, so that the second sliding part is always inserted in the fixed groove, avoiding the hinge rod from sliding at will, and ensuring the connection stability of the connecting components.
[0011] Optionally, the mounting component has a first sliding groove on its end face, and the first sliding groove has an opening on one side wall of the mounting component. The fixing component has a first sliding member on its end face that is adapted to the first sliding groove. The first sliding member can be inserted into the first sliding groove. The end face of the first sliding groove is T-shaped, and the width of the opening of the first sliding groove is smaller than the width of the bottom of the groove.
[0012] By adopting the above technical solution, by setting a first sliding member, the first sliding member can be inserted into the first sliding groove, so that the fixing member can be fixedly connected with the mounting member by inserting the first sliding member into the first sliding groove. The T-shaped first sliding groove can prevent the first sliding member from coming out of the groove, thereby facilitating the assembly and disassembly of the mounting member and the fixing member, making it easy to place the overhead insulated cable in the cylinder formed by the two, while ensuring the clamping stability of the fixing component on the cable.
[0013] Optionally, the end face of the first sliding member is machined into a protruding arc surface.
[0014] By adopting the above technical solution, the end face of the first sliding member is processed into a protruding arc surface, which facilitates the insertion of the first sliding member into the first sliding groove, making the insertion process smoother, reducing the installation difficulty, improving the assembly efficiency of the fixing part and the mounting part, and avoiding the jamming problem caused by the edge of the end face.
[0015] Optionally, the bottom of the first sliding groove is provided with a circular limiting hole, and the surface of the first sliding member is provided with a circular receiving hole. The receiving hole connects the surface of the first sliding member and the outer peripheral wall of the fixing member. A limiting post is slidably arranged in the receiving hole, and the end of the limiting post is adapted to the limiting hole. The end of the limiting post can be inserted into the limiting hole.
[0016] By adopting the above technical solution and setting a limiting post, after the first sliding member is inserted into the first sliding groove, the limiting post can be inserted into the limiting hole, thereby restricting the movement of the fixing member along the length direction of the first sliding groove, preventing the fixing member from accidentally separating from the mounting member, enhancing the reliability of the fixing assembly for clamping the cable, and ensuring that the cable is not easily loosened after fixing.
[0017] Optionally, the end of the limiting post inserted into the limiting hole is machined into a hemispherical surface.
[0018] By adopting the above technical solution, the end of the limiting post is processed into a hemispherical surface, which can play a guiding role when the limiting post is inserted into the limiting hole, reduce the resistance during insertion, and make it easier for the limiting post to be inserted into the hole. At the same time, when disassembly is required, the hemispherical structure also facilitates the external force to push the limiting post out of the limiting hole, thus improving the convenience of operation.
[0019] Optionally, the receiving hole wall is coaxially provided with an annular groove, and the peripheral wall of the limiting post is coaxially sleeved with a baffle adapted to the annular groove. The baffle is slidably disposed in the annular groove, and a spring is disposed in the annular groove. The spring is sleeved on the peripheral wall of the limiting post, one end of the spring is fixedly connected to the baffle away from the plate surface of the first sliding member, and the other end of the spring is fixedly connected to the end wall of the annular groove away from the first sliding member.
[0020] By adopting the above technical solution, and by setting a baffle and a spring, the elastic force of the spring can be used to push the baffle, so that the limiting post always maintains the tendency to be inserted into the limiting hole. This ensures that the limiting post is stably inserted into the limiting hole when there is no external force, and prevents the limiting post from coming out of the limiting hole due to vibration or other factors. This further enhances the stability of the connection between the fixing part and the mounting part, and ensures the structural reliability of the fixing component.
[0021] Optionally, a U-shaped operating frame is fixedly connected to the end face of the rotating column away from the hinge rod. Both ends of the operating frame are fixedly connected to the end face of the rotating column, and the U-shaped opening of the operating frame faces the rotating column.
[0022] By adopting the above technical solution and setting up an operating frame, a force application point can be provided for rotating the rotating column. The operator can more easily rotate the rotating column through the operating frame, thereby adjusting the angle of the rotating column, so that the second sliding block can be accurately aligned with the fixed groove after sliding in the second sliding groove, improving the convenience of adjusting the connecting components and facilitating the quick completion of the connection between different installation parts.
[0023] In summary, this application has the following technical effects:
[0024] 1. By setting up mounting components, fixing components, a first mounting cylinder, a second mounting cylinder, a hinge rod, a rotating column, and a second sliding block, when connecting two mounting components, the rotating column and hinge rod of one mounting component are inserted into the second mounting cylinder of the other mounting component, and the second sliding block slides in the second sliding groove. The opposite end faces of the first and second mounting cylinders abut against each other, and the two side walls of the two mounting components are flush with each other. By rotating the rotating column, the second sliding block is inserted into the fixing groove, and the two mounting components are hinged together. This allows multiple mounting components to adjust their angles by adding or removing mounting components when adding or removing overhead insulated cables, thereby adapting to the interval installation of different numbers of overhead insulated cable bundles, reducing the tedious operation of changing clamps in high-altitude operations, and improving installation efficiency.
[0025] 2. By setting a first sliding member, the first sliding member can be inserted into the first sliding groove, which enables the fixing member to be fixedly connected with the mounting member by inserting the first sliding member into the first sliding groove. The T-shaped first sliding groove can prevent the first sliding member from coming out of the groove, thereby facilitating the assembly and disassembly of the mounting member and the fixing member, making it easy to place the overhead insulated cable in the cylinder formed by the two, while ensuring the clamping stability of the fixing component on the cable.
[0026] 3. By setting a limiting post, after the first sliding member is inserted into the first sliding groove, the limiting post can be inserted into the limiting hole, thereby restricting the movement of the fixing member along the length direction of the first sliding groove, preventing the fixing member from accidentally separating from the mounting member, enhancing the reliability of the fixing assembly for clamping the cable, and ensuring that the cable is not easily loosened after fixing.

The end of the limiting post 13 inserted into the limiting hole 112 is processed into a hemispherical surface to facilitate the insertion of the end of the limiting post 13 into the limiting hole 112. The end of the peripheral wall of the limiting post 13 away from the first sliding member 121 is coaxially provided with a first thickened part 131 in an annular shape to facilitate the separation of the limiting post 13 from the limiting hole 112.

[0037] Combination Figure 1 and Figure 2 A hinge rod 23 is slidably disposed inside the first mounting cylinder 21. The hinge rod 23 is a round rod. The peripheral wall of the hinge rod 23 is slidably attached to the inner peripheral wall of the first mounting cylinder 21. A second thickened part 231 in an annular shape is coaxially fixed to the end wall of the hinge rod 23 away from the second mounting cylinder 22. A spring is disposed between the second thickened part 231 and the first mounting cylinder 21. The spring is sleeved on the peripheral wall of the hinge rod 23. The two ends of the spring are fixedly connected to the surfaces of the first mounting cylinder 21 and the second thickened part 231, respectively.
[0038] Combination Figure 1 and Figure 2 A rotating column 24 is rotatably mounted on the end face of the hinge rod 23 away from the second thickened portion 231. The rotating column 24 is cylindrical and coaxially arranged with the hinge rod 23, with its peripheral wall flush with the peripheral wall of the hinge rod 23. A rotating shaft (not shown in the figure) is fixedly connected to the end face of the hinge rod 23, and the rotating shaft passes through the rotating column 24, rotatably positioning the rotating column 24 on the end face of the hinge rod 23. A second sliding member 241 is fixedly connected to the peripheral wall of the rotating column 24.
