Description

Technical Field

[0001] The present application relates to the technical field of tunnel equipment, and specifically to a power tunnel support. Background Art

[0002] The power tunnel support is a comprehensive tunnel that uses steel tube concrete as the tunnel corridor structure, and is equipped with a ring cable support system and lighting devices inside it for laying power cables. Traditional power tunnel supports are often installed using shield-type supports, and support arms are installed on the supports to support the cables.

[0003] An existing patent (publication number: CN211556817U) discloses a power tunnel support, including a ring support, a support connecting plate, a support arm, a crossbeam, a center beam and a beam-column support arm. Multiple support arms are arranged on the ring support in sequence from the top to the bottom of the ring support, and multiple beam-column support arms are arranged on both sides of the center beam in sequence from the top to the bottom of the center beam. The inner arc surfaces of the two ring supports are arranged facing each other on the inner wall of the tunnel, and the tops of the two ring supports are connected to the center beam at the top of the inner wall of the tunnel through the support connecting plate and installed at the connection of the two ring supports, and the center beam is installed on the two ring supports through the crossbeam.

[0004] The above-mentioned comparative document points out that the power tunnel support can add multiple beam-column support arms to the central beam at any time according to actual needs to accommodate more cables without re-disassembly, thereby increasing the number of cables accommodated in the tunnel space and being easy to use. The support arms and beam-column support arms are connected to the arc-shaped support and the central beam by bolts or screws. During long-term use, due to the relatively humid environment inside the tunnel, the support arms and beam-column support arms may be easily corroded and damaged, requiring replacement of the support arms and beam-column support arms. During replacement, the bolts or screws need to be unscrewed and the damaged support arms and beam-column support arms removed. The new support arms and beam-column support arms are then re-fixed to the arc-shaped support or the central beam with bolts or screws. The disassembly and installation process is cumbersome and time-consuming, resulting in low replacement efficiency. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present application provides a power tunnel support having the advantages of being easy to disassemble, thereby solving the problem of the inconvenience of disassembling the support arm, which is not conducive to the warranty and maintenance of the support arm.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an electric power tunnel support, comprising a tunnel and a plurality of connecting plates, wherein the inner walls of the tunnel are connected to circular supports by bolts, a plurality of support legs are fixedly connected to the surface of the circular supports, a plurality of T-slots are provided on both sides of the plurality of support legs, a connecting plate groove is provided inside the plurality of support legs, three springs are fixedly connected to the upper end of the connecting plate groove, a spring fixing block is fixedly connected to the lower end of the three springs, a handle is fixedly connected to both sides of the spring fixing block, the handle passes through the T-slot and extends to the surface of the support legs, an extension plate is fixedly connected to one end of the plurality of connecting plates, a bevel fixing plate is fixedly connected to the upper end of the extension plate, the extension plate extends into the interior of the connecting plate groove and abuts against the lower end of the spring fixing block.

[0007] Through the above scheme, the device can be easily disassembled. By setting the spring fixing block, handle and spring, if the connecting plate needs to be repaired and maintained, pushing the handle upward will drive the spring fixing block and the spring to move upward together so that the spring fixing block no longer blocks the inclined fixing plate, and then the entire bracket arm can be taken out, which is convenient for the staff to disassemble.

[0008] Furthermore, the circular bracket is internally threaded with two groups of screws, each group consisting of two screws distributed in a mirror image.

[0009] Through the above solution, the entire supporting structure can be fixed by setting screws.

[0010] Furthermore, the two screws in the two groups of screws that are distributed laterally are both slidably sleeved with a crossbeam connecting plate on the outside, and the screws in the two groups of screws that are distributed vertically are both slidably sleeved with a middle beam connecting plate on the outside.

[0011] Through the above solution, the two center beam connecting plates and the cross beam connecting plates are connected by setting screw threads, which makes it easy to disassemble the center beam connecting plates and the cross beam connecting plates.

[0012] Furthermore, a crossbeam is fixedly connected between the two crossbeam connecting plates.

[0013] Through the above solution, the lateral support of the entire structure is ensured by setting the crossbeams.

[0014] Furthermore, a folding plate is fixedly connected to the lower end of one of the two center beam connecting plates located at the upper end.

[0015] According to the above solution, the center beam and the folding plate are separately provided and connected by hinges, so that the folding plate can be turned over.

[0016] Furthermore, the upper end of one of the two center beam connecting plates located at the lower end is fixedly connected to the center beam, and the center beam and the cross beam are fixedly connected.

[0017] Through the above solution, the center beam and the cross beam are fixedly connected to support the entire circular bracket.

[0018] Furthermore, a hinge is fixedly connected to the lower end of the folding plate, and the hinge surface is fixedly connected to the upper end of the center beam.

[0019] According to the above solution, the hinge is provided to facilitate folding.

[0020] Furthermore, the handle surface is slidably connected to the inner wall of the T-slot.

[0021] According to the above solution, the handle surface is slidably connected to the inner wall of the T-slot, so that the T-slot achieves a limiting function.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The invention relates to a quick-detachable rescue fire window system, wherein three springs are fixedly connected inside a connecting plate groove, a spring fixing block is fixedly connected to the lower end of the spring, and handles are fixedly connected on both sides of the fixing block. The handles are slidably connected to the inner wall of the T-slot and extend through the T-slot to the surface of the bracket leg. At the same time, the extension plate extends into the connecting plate groove and abuts against the lower end of the spring fixing block. When the bracket support arm needs to be replaced, the staff needs to hold the handle and then pull the handle upward. The upward movement of the handle will drive the spring fixing block to move upward until the lower end surface of the spring fixing block is higher than the uppermost end of the inclined fixing plate. At this time, the spring fixing block will not interfere with the inclined fixing plate and then the bracket support arm can be pulled out. When the new bracket arm needs to be installed, the inclined fixing plate is aligned with the connecting plate slot and then the inclined fixing plate is inserted into the connecting plate slot. The inclined fixing plate will move toward the inside of the connecting plate slot. When the inclined fixing plate contacts the spring fixing block, it will continue to move inward. Because the inclined fixing plate is an inclined surface, when the inclined fixing plate continues to move, it will push the spring fixing block to move upward. At this time, the spring will be compressed by the upward force of the spring fixing block, and then continue to move the inclined fixing plate until the inclined surface of the inclined fixing plate no longer contacts the lower end surface of the spring fixing block. The spring will push the spring fixing block to move downward until the lower end surface of the spring fixing block abuts against the upper end of the extension plate to complete the installation of the bracket arm. Therefore, the disassembly and installation process of the staff will not be cumbersome and time-consuming, resulting in low replacement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , a quick-detachable rescue fire window system in this embodiment includes a tunnel 2 and a plurality of connecting plates 5. The inner walls of the tunnel 2 are connected to a circular bracket 1 by bolts. A plurality of bracket legs 3 are fixedly connected to the surface of the circular bracket 1. Multiple T-slots 4 are provided on both sides of the multiple bracket legs 3. Connecting plate grooves 16 are provided inside the multiple bracket legs 3. Three springs 10 are fixedly connected to the upper end of the connecting plate groove 16. The lower ends of the three springs 10 are commonly fixedly connected to a spring fixing block 8. Handles 9 are fixedly connected to both sides of the spring fixing block 8. The handles 9 pass through the T-slot 4 and extend to the surface of the bracket leg 3. One end of the multiple connecting plates 5 is fixedly connected to an extension plate 6. The upper end of the extension plate 6 is fixedly connected to an inclined fixing plate 7. The extension plate 6 extends into the interior of the connecting plate groove 16 and abuts against the lower end of the spring fixing block 8.

[0033] See also Figure 1 and Figure 4The circular bracket 1 is internally threaded with two groups of screws 17, each group of which is composed of two screws 17 distributed in a mirror image. The two screws 17 distributed horizontally in the two groups of screws 17 are both slidably sleeved with a crossbeam connecting plate 11 on the outside, and the screws 17 distributed vertically in the two groups of screws 17 are both slidably sleeved with a center beam connecting plate 15 on the outside. The two crossbeam connecting plates 11 are fixedly connected with a crossbeam 12, and the lower end of the middle beam connecting plate 15 located at the upper end of the two center beam connecting plates 15 is fixedly connected to a folding plate 18, and the upper end of the middle beam connecting plate 15 located at the lower end of the two center beam connecting plates 15 is fixedly connected to the center beam 14, and the lower end of the folding plate 18 is fixedly connected to a hinge 13, and the surface of the hinge 13 is fixedly connected to the upper end of the center beam 14.

[0034] In this embodiment, the device is adjusted by setting a spring fixing block 8, a handle 9, and a spring 10. If it is necessary to remove the bracket arm, the handle 9 is adjusted upward to move in the T-slot 4. When the handle 9 is adjusted, the spring fixing block 8 will be driven to move together in the connecting plate slot 16. When moving upward, the spring 10 will be compressed, thereby moving the whole upward. When it reaches a certain position, the inclined fixing plate 7 will not be blocked by the spring fixing block 8, so that the entire bracket arm can be taken out.

[0035] It should be noted that the center beam 14 and the cross beam 12 are fixedly connected, and when the center beam 14 is flipped, the cross beam 12 can be flipped synchronously.

[0036] The working principle of the above embodiment is:

[0037] When the device is in use, the construction worker removes the screws 17, then flips the middle beam 14 and flips the middle beam 14 and the cross beam 12 up to facilitate the passage of the staff during inspection. Then the staff needs to hold the handle 9 and pull the handle 9 upward. The upward movement of the handle 9 will drive the spring fixing block 8 to move upward until the lower end surface of the spring fixing block 8 is higher than the uppermost end of the inclined fixing plate 7. At this time, the spring fixing block 8 will not interfere with the inclined fixing plate 7 and then the bracket arm can be pulled out. When the new bracket arm needs to be installed, the inclined fixing plate 7 is aligned with the connecting plate groove 16 and then the inclined fixing plate 7 is inserted into the connecting plate groove 16. The inclined fixing plate 7 will move toward the inside of the connecting plate groove 16. When the inclined fixing plate 7 contacts the spring fixing block 8, it continues to move inward. Because the inclined fixing plate 7 is an inclined surface, when the inclined fixing plate 7 continues to move, it will push the spring fixing block 8 to move upward. At this time, the spring 10 will be compressed by the upward force of the spring fixing block 8, and then continue to move the inclined fixing plate 7 until the inclined surface of the inclined fixing plate 7 no longer contacts the lower end surface of the spring fixing block 8. The spring 10 will push the spring fixing block 8 to move downward until the lower end surface of the spring fixing block 8 abuts against the upper end of the extension plate 6, and the installation of the bracket arm is completed.
