Description

Technical Field

[0001] This utility model relates to the field of cable installation and fixing technology, and in particular to a high-voltage cable laying support structure for cable tunnels. Background Technology

[0002] Currently, the high-voltage cable laying support structure in cable tunnels is a device used to support and fix high-voltage cables within the tunnel. It mainly consists of the support body, brackets, clamps, and other parts.

[0003] A high-voltage cable support structure for cable tunnels is disclosed in Chinese utility model patent with announcement number CN221978531U. Although the above-mentioned prior art is simple to operate, improves the efficiency of cable installation and removal, and facilitates cable maintenance, the space inside the cable tunnel is limited. After the cable support is installed, a long extension will be generated. When the supports are installed on both sides of the tunnel, the extension on both sides will occupy a lot of tunnel space, reducing the available space inside the tunnel, increasing the difficulty of cable laying and installation, and making it inconvenient for external equipment to be used inside the tunnel. Therefore, a cable laying support structure that can be folded and stored when not in use is designed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-voltage cable laying support structure for cable tunnels.

[0005] This utility model is achieved by the following technical solution: a high-voltage cable laying support structure for a cable tunnel, including multiple support rods installed inside the tunnel, each support rod having a support component that can be folded up on one side when not in use, and each support component having a locking component that can lock the support component when it is unfolded, the support component including a first support block fixedly installed on one side of the support rod and a second support block rotatably installed on one side of the first support block.

[0006] With the above technical solution, the sliding locking component can release the restriction effect on the support component when the cable is not supported. This allows the support component to bend, bending the support part that extends vertically into the tunnel into a position close to the tunnel wall. This prevents the support component from obstructing the tunnel interior and hindering the activities of workers and the use of construction equipment.

[0007] As a further improvement to the above solution, a third support block is rotatably mounted on the side of each first support block near the second support block, and a support groove adapted to the third support block is opened on one side of each first support block.

[0008] Through the above technical solution, when the third support block rotates into the interior of the support groove, it can support the second support block and prevent the insufficient supporting force of the second support block.

[0009] As a further improvement of the above solution, a limiting plate is provided on the top of each of the second support blocks, and the limiting plate is arranged in a "C" shape.

[0010] Through the above technical solution, the limiting plate will limit all the cables above the second support block, which is convenient for the second support block to support the cables.

[0011] As a further improvement of the above solution, insertion slots penetrating the adjacent support grooves are provided on both sides of the top of each of the second support blocks, and both ends of the limiting plate are inserted into the adjacent insertion slots.

[0012] Through the above technical solution, when the limiting plate is inserted into the interior of the insertion slot, its left and right movement can be restricted.

[0013] As a further improvement of the above solution, a fixing port is provided on one side of each of the limiting plates close to the third support block, and each fixing port is adapted to the adjacent third support block.

[0014] Through the above technical solution, when the third support block is inserted into the fixing port of the limiting plate, the limiting plate cannot be detached from the insertion slot, avoiding the loosening of the limiting plate.

[0015] As a further improvement of the above solution, two sliding slots are provided on one side of each of the second support blocks, and the locking component includes a baffle provided on one side of the third support block and two sliding bars fixedly installed on the baffle, and each sliding bar is slidably matched with the adjacent sliding slot.

[0016] Through the above technical solution, the baffle will limit the position of the third support block and prevent the third support block from detaching from the support groove. [[ID=2S]]

[0017] As a further improvement of the above solution, two mounting blocks are fixedly installed on one side of each of the second support blocks, two first magnets are fixedly installed on the two mounting blocks, two second magnets are fixedly installed on one side of each baffle close to the mounting block, and each first magnet is adapted to the adjacent second magnet.

[0018] Through the above technical solution, the second magnet and the first magnet attract each other, which will limit the position of the baffle and avoid the baffle moving by itself in cooperation with the sliding bar.

[0019] As a further improvement of the above solution, a fourth support block fixedly installed with the adjacent support rod is provided at the bottom of each of the first support blocks.

[0020] Through the above technical solution, the fourth support block will provide a certain auxiliary support effect for the first and second support blocks.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention, through a support component and a locking component, allows the sliding locking component to release the restriction effect on the support component when the cable is not being supported. This enables the support component to bend, bending the support portion that extends vertically into the tunnel into a position close to the tunnel wall. This prevents the support component from obstructing the tunnel interior and hindering the activities of workers and the use of construction equipment. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Please combine Figures 1-5, A high-voltage cable laying support structure for a cable tunnel in this embodiment includes a plurality of support rods 1 arranged inside the tunnel. On one side of each support rod 1, there is a support component that can be folded and retracted during idle time. On each support component, there is a locking component that can lock the support component after it is unfolded. The support component includes a first support block 201 fixedly installed on one side of the support rod 1 and a second support block 202 rotatably installed on one side of the first support block 201.

[0032] The sliding locking component can解除 the restrictive effect on the support component, so that the support component can be bent, and the support part extending vertically into the tunnel can be bent close to the inner wall of the tunnel.

[0033] On one side of each first support block 201 close to the second support block 202, a third support block 4 is rotatably installed. On one side of each first support block 201, a support groove 5 adapted to the third support block 4 is opened.

[0034] When the third support block 4 rotates into the interior of the support groove 5, it can support the second support block 202 and prevent the insufficient supporting force of the second support block 202.

[0035] On the top of each second support block 202, a limiting plate 6 is provided, and the limiting plate 6 is arranged in a "C" shape.

[0036] The limiting plate 6 will限制 all the cables above the second support block 202, which is convenient for the second support block 202 to support the cables.

[0037] On both sides of the top of each second support block 202, insertion slots penetrating through the adjacent support grooves 5 are opened, and both ends of the limiting plate 6 are inserted into the adjacent insertion slots.

[0038] When the limiting plate 6 is inserted into the interior of the insertion slot, it can限制 its left and right movement.

[0039] On one side of each limiting plate 6 close to the third support block 4, a fixing port is opened, and each fixing port is adapted to the adjacent third support block 4.

[0040] When the third support block 4 is inserted into the fixing port of the limiting plate 6, the limiting plate 6 cannot脱离 from the insertion slot, avoiding the loosening of the limiting plate 6. |>

[0041] On one side of each second support block 202, two sliding grooves 7 are opened. The locking component includes a baffle 301 arranged on one side of the third support block 4 and two sliding strips 302 fixedly installed on the baffle 301. Each sliding strip 302 is slidably配合 with the adjacent sliding groove 7.

[0042] The baffle 301 will限制 the position of the third support block 4 and prevent the third support block 4 from脱离 from the support groove 5. It should be noted that the Chinese text contains some typos or unclear expressions. For example, "解除" should be "解除", "限制" should be "限制", "脱离" should be "脱离", and "配合" should be "配合". In the translation, these words are translated according to the correct meaning. Also, some of the "<00000XX>" tags seem to be incomplete or unclear in their function in the context, but they are preserved as required without further modification.

[0043] Two mounting blocks 8 are fixedly installed on one side of each second support block 202. A first magnet 9 is fixedly installed on each of the two mounting blocks 8. Two second magnets 10 are fixedly installed on the side of each baffle 301 near the mounting block 8. Each first magnet 9 is adapted to the adjacent second magnet 10.

[0044] When the second magnet 10 and the first magnet 9 attract each other, the position of the baffle 301 will be restricted, preventing the baffle 301 from moving on its own in conjunction with the slider 302.

[0045] Each first support block 201 has a fourth support block 11 at its bottom, which is fixedly installed with the adjacent support rod 1.

[0046] The fourth support block 11 will provide some auxiliary support to the first support block 201 and the second support block 202.

[0047] The implementation principle of a high-voltage cable laying support structure for a cable tunnel in this application embodiment is as follows: when laying cables, rotating the second support block 202 will cause the second support block 202 to move away from the inner wall of the tunnel and extend towards the center of the tunnel.

[0048] The cable is laid on the second support block 202 and the limiting plate 6 is inserted. The limiting plate 6 will restrict the position of the cable to prevent the cable from falling.

[0049] After the limiting plate 6 is inserted, the baffle 301 can be slid and the sliding bar 302 can be used to remove the baffle 301 from one side of the second support block 202. Then, the third support block 4 is rotated and inserted into the support groove 5 of the second support block 202. In this way, the third support block 4 will not only be in the support groove 5, but also inside the fixing opening of the limiting plate 6, so the limiting plate 6 cannot be pulled out from the insertion groove.

[0050] Finally, insert the sliding bar 302 into the sliding groove 7, so that one side of the baffle 301 is in contact with the third support block 4, and the second magnet 10 is attracted to the first magnet 9. In this way, the baffle 301 will prevent the third support block 4 from automatically sliding out of the support groove 5. The two magnets will also prevent the baffle 301 from automatically sliding out of the sliding groove 7 due to vibration and the sliding bar 302, so that it can not limit the third support block 4.

[0051] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
