Description

Technical Field

[0001] This utility model relates to the field of tunnel repair support technology, specifically a tunnel repair support. Background Technology

[0002] For roadway repair machines mainly used in coal mine operations, due to the limited space in the working environment, it is generally desirable to maximize the working range and diversify the working capabilities of the equipment itself. In other words, it is desirable for one machine to achieve multiple required working capabilities and maximize the working range. After roadway repair, roadway repair supports are needed to support the roadway, thereby performing operations such as anchor fixing and grouting. Therefore, roadway repair supports are required.

[0003] The existing publication CN203308477U discloses a collapsible iron strut for mining, including a strut body and a strut head. The strut body is fitted inside the strut head, and a spring is installed inside the strut body. The two ends of the spring press against the end cap and the screw rod, respectively. A fixed end cap, the same shape as the end cap, is welded to the end of the screw rod. This utility model, by using the iron strut, effectively strengthens the I-beam support structure. During construction, there have been no instances of support collapse, blasting damage, or collapse, ensuring the safety of tunnel construction. Simultaneously, it reduces the support repair rate, alleviates the labor intensity of workers, increases the construction site space, and achieves good safety benefits.

[0004] However, current roadway repair operations generate a large amount of dust during the repair process. The existing repair supports are not equipped with effective dust suppression devices, resulting in a large amount of dust filling the entire roadway space during repair support work. This significantly reduces visibility within the roadway, severely impacting the operators' vision and hindering their normal work. It also seriously pollutes the air quality within the roadway. Long-term exposure to this dusty environment will undoubtedly have an adverse effect on the operators' health. Furthermore, after completing the repair task, the existing roadway repair supports need to be dismantled to avoid negatively impacting the support effect of the existing support system. If the repair supports are not dismantled in a timely manner, they and the already installed support system will occupy valuable space resources in the roadway. However, in practice, the dismantling of the existing repair supports, especially the top support plate, is particularly cumbersome and complex, making rapid dismantling impossible. This design flaw leads to numerous inconveniences during installation and dismantling, thus affecting overall operational efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of inconvenient operation and poor dust prevention in the existing technology, and to provide a tunnel repair support.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tunnel repair support, comprising:

[0008] The top plate has fitting grooves on both sides inside, and the fitting grooves are in the shape of an "I". Fitting plates are fitted inside the fitting grooves. A connecting plate is fixedly installed on one side of the fitting plate. A water spray plate is fixedly installed on one side of the bottom of the top plate. An atomizing nozzle is fixedly installed on one side of the water spray plate. A high-pressure hose is fixedly installed in the middle of the other side of the water spray plate. A water pump is fixedly installed at the bottom of the high-pressure hose. A water tank is fixedly installed at the bottom of the water pump. A sealing cover is rotatably connected to the top side of the water tank. A level gauge is fixedly installed on one side of the water tank.

[0009] In a preferred embodiment, a support rod is fixedly installed at the top center of the top plate, and hinges are rotatably connected to both sides of the support rod. The hinges are structures used to drive the support plate to flip.

[0010] In a preferred embodiment, a support plate is rotatably connected to one side of the hinge, and two hydraulic rods are fixedly installed on both sides of the bottom of the top plate. The hydraulic rods are structures used to push the top plate to adjust its height.

[0011] In a preferred embodiment, the hydraulic rod is covered with a dust cover, and a base is fixedly installed at the bottom of the hydraulic rod, the base being a structure for supporting the bottom.

[0012] In a preferred embodiment, a support block is fixedly installed on one side of the bottom of the connecting plate. The support block is triangular in shape and is a structure used to provide auxiliary support for the connecting plate.

[0013] In a preferred embodiment, a sliding plate is fixedly installed on one side of the connecting plate, and reinforcing rods are fixedly installed on the upper and lower sides of the sliding plate, the reinforcing rods being structures for reinforcement.

[0014] In a preferred embodiment, a central plate is slidably connected to one side of the sliding plate, and a reinforcing plate is fixedly installed at the bottom of the central plate. The reinforcing plate is a structure used to reinforce the central plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The tunnel repair support allows water to be added to the water tank by rotating and opening the sealing cover. The water level in the tank is monitored by a level gauge. The water is then pumped out by a water pump and sent into the spray plate through a high-pressure hose. The water is then atomized and sprayed out through atomizing nozzles on one side of the spray plate to reduce dust in the repaired tunnel, thus avoiding excessive dust that could obstruct visibility and pollute the environment.

[0017] 2. This tunnel repair support uses hinges to rotate the support plate, thereby opening the top of the roof plate. The fitting plate is then placed into the fitting groove inside the roof plate, supporting the sliding plate and the center plate. The sliding plate slides inside the center plate, causing it to move to both sides within the center plate, thus adjusting the width. The supporting force of the sliding plate is strengthened by reinforcing rods, and the supporting force of the center plate is strengthened by reinforcing plates. This improves the convenience and supporting force of the tunnel repair support. At the same time, the fitting plate is quickly connected to the center plate by placing it into the fitting groove, which also facilitates the quick disassembly of the center plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Combined with appendix Figure 1-4 In this embodiment, a tunnel repair support includes: a top plate 1, with fitting grooves 11 on both sides of the interior of the top plate 1, the fitting grooves 11 being in the shape of an "I"; a support rod 12 is fixedly installed in the middle of the top of the top plate 1; hinges 13 are rotatably connected to both sides of the support rod 12; a support plate 14 is rotatably connected to one side of the hinge 13; two hydraulic rods 15 are fixedly installed on both sides of the bottom of the top plate 1; dust covers 16 are wrapped around the outside of the hydraulic rods 15; and a base 17 is fixedly installed at the bottom of the hydraulic rods 15.

[0025] Specifically, by using the dust cover 16 to effectively wrap the outside of the hydraulic rod 15, dust and impurities can be prevented from entering the hydraulic system, ensuring its normal operation. At the same time, the flexible flipping of the two sides of the support rod 12 and the hinge 13 can effectively drive the support plate 14 to perform the corresponding flipping action. This design allows the top of the top plate 1 to be opened smoothly, providing convenience for the tunnel repair work. In addition, the base 17 provides solid support for the bottom of the tunnel repair bracket, ensuring the stability and safety of the bracket. The fitting connection between the fitting groove 11 and the fitting plate 2 not only enhances the stability of the structure, but also greatly improves the convenience of installing the tunnel repair bracket, making the entire installation process more efficient and simple.

[0026] The fitting groove 11 is fitted with a fitting plate 2. A connecting plate 21 is fixedly installed on one side of the fitting plate 2. A support block 22 is fixedly installed on the bottom side of the connecting plate 21. The support block 22 is triangular in shape. A sliding plate 23 is fixedly installed on one side of the connecting plate 21. Reinforcing rods 24 are fixedly installed on the upper and lower sides of the sliding plate 23. A center plate 25 is slidably connected to one side of the sliding plate 23. A reinforcing plate 26 is fixedly installed at the bottom of the center plate 25.

[0027] Specifically, the connection with the interlocking plate 2 is achieved by using a connecting plate 21, thereby ensuring the integrity of the entire structure. The bottom support block 22 of the connecting plate 21 provides additional auxiliary support to ensure the stability of the connecting plate 21. The sliding plate 23 can slide freely to both sides inside the center plate 25. This design allows the width of the roadway repair support to be flexibly adjusted according to actual needs. In order to further enhance the structural strength of the sliding plate 23, a reinforcing rod 24 is used for reinforcement. At the same time, a reinforcing plate 26 is also applied to the center plate 25 to enhance its structural robustness. The comprehensive application of these designs significantly improves the overall stability and support force of the roadway repair support, ensuring reliability and safety in repair operations.

[0028] A water spray plate 3 is fixedly installed on one side of the bottom of the top plate 1. An atomizing nozzle 31 is fixedly installed on one side of the water spray plate 3. A high-pressure hose 32 is fixedly installed in the middle of the other side of the water spray plate 3. A water pump 33 is fixedly installed at the bottom of the high-pressure hose 32. A water tank 34 is fixedly installed at the bottom of the water pump 33. A sealing cover 35 is rotatably connected to one side of the top of the water tank 34. A level gauge 36 is fixedly installed on one side of the water tank 34.

[0029] Specifically, the water level inside the water tank 34 can be observed using the level gauge 36. When dust control operations are required, the water in the water tank 34 can be effectively pumped out by starting the water pump 33. Subsequently, this water is transported to the interior of the spray plate 3 through the high-pressure hose 32. On one side of the spray plate 3, the atomizing nozzle 31 further atomizes this water into fine water droplets, which are then sprayed evenly. This spraying method can effectively cover the dust in the tunnel and significantly improve the dust control effect of the tunnel repair support. In this way, the pollution problem caused by dust to the surrounding environment is avoided.

[0030] Working principle: First, place the two bases 17 parallel to each other. The hydraulic rods 15 on both sides of the top of the bases 17 push the top plate 1 upwards, adjusting the two top plates 1 to a symmetrical height. The dust cover 16 wraps around the outside of the hydraulic rods 15, providing dust protection. Flipping the support plate 14 causes the hinges 13 on both sides of the support rod 12 to flip, thus flipping the support plate 14 and opening the top of the top plate 1. The fitting plate 2 is then placed into the fitting groove 11 on one side of the top of the top plate 1, thus fitting the center plate 25 and the sliding plate 23 together. Releasing the support plate 14 causes the hinges 13 to flip automatically, closing the support plate 14 and supporting the top of the top plate 1. The bottom of the connecting plate 21 provides support. Support block 22 provides auxiliary support for connecting plate 21. Sliding plate 23 slides inside center plate 25, causing the two sliding plates 23 to move to both sides, thereby adjusting the width of the tunnel repair support. Reinforcing rod 24 strengthens sliding plate 23, and reinforcing plate 26 reinforces center plate 25, thereby improving the support force and stability of the tunnel repair support. The sealing cover 35 is opened by rotating, and water is added to the water tank 34. The water is pumped out of the water tank 34 by the operation of water pump 33 and sent into the water spray plate 3 through high pressure hose 32. The water is atomized and sprayed out through atomizing nozzle 31 on one side of water spray plate 3, thereby covering dust and avoiding dust pollution, thus improving the dustproof effect of the tunnel repair support.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
