Description

Technical Field

[0001] This utility model relates to the field of tunneling device technology, specifically a rapid tunneling device for breaking up roof slabs. Background Technology

[0002] With the widespread use of fully mechanized tunneling machines (MTMs) in coal mines, the efficiency of underground mining has greatly improved compared to the traditional drilling and blasting methods. However, due to the influence of the roof rock conditions, especially in coal mine tunneling where the roof coal seam is easily broken, the roof pressure is high, and coal wall spalling is prone to occur at the face, posing significant safety hazards. An MTM, short for fully mechanized tunneling machine, is a comprehensive mechanized equipment that integrates multiple functions such as tunneling, rock loading, coal transportation, and even support and track laying. Based on the way the working structure acts on the surrounding rock: it is divided into two main categories: full-face tunneling machines and partial-face tunneling machines. Based on the object of operation: it is divided into ordinary machines and tunnel boring machines (TBMs). Among them, TBMs are comprehensive equipment that uses mechanical rock breaking, muck removal, and support for continuous operation. Based on the operating method: it is divided into open-face TBMs and shield tunneling machines. Among the former, the most well-known is the large-diameter full-face rock tunnel boring machine, which is a complete set of tunneling equipment that integrates excavation, support, and muck removal. It is known as the "aircraft carrier" and "king of tunneling machines" in the field of engineering machinery. Among the latter, the most well-known is the shield tunneling machine.

[0003] Existing rapid tunneling devices for broken roofs support only the broken roof itself, using a single support structure. This approach is problematic because the support structure is not easily fixed to the tunnel, and the fixing points are often not deep enough. Consequently, the support structure lacks stability and its support effect is poor, making it prone to collapse during tunneling and negatively impacting the overall support performance after tunneling. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that existing technologies are not convenient for supporting broken roofs, thus affecting the tunneling speed, and to provide a rapid tunneling device for broken roofs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid tunneling device for breaking up roofs includes:

[0007] The pump has an extraction pipe fixedly installed on one side, a storage tank fixedly installed on one side of the extraction pipe, a diversion valve fixedly installed on the top of the pump (the diversion valve is T-shaped), diversion pipes fixedly installed inside both sides of the diversion valve (the diversion pipes are L-shaped), a cross valve fixedly installed on the top of the diversion pipes (the cross valve is cross-shaped), a delivery pipe fixedly installed inside both sides and the top of the cross valve, a nozzle fixedly installed on the top of the delivery pipe, a support plate fixedly installed on the outside of the nozzle, and four lifting rods fixedly installed around the bottom of the support plate.

[0008] In a preferred embodiment, a roadheader is fixedly installed at the bottom of the extraction pump, and two support blocks are fixedly installed on one side of the top of the roadheader. The support blocks are structures used for support.

[0009] In a preferred embodiment, the support block is triangular in shape, and a drill bit is installed in the middle of one side of the tunneling machine. The support block is a structure used to support the fixed groove.

[0010] In a preferred embodiment, two telescopic columns are fixedly installed on the top right side of the tunneling machine, and a drilling machine is fixedly installed on the top of the telescopic columns. The drilling machine is a structure used for drilling holes.

[0011] In a preferred embodiment, a fixed plate is fixedly installed on the top of one side of the roadheader, and two telescopic rods are fixedly installed on both sides inside the fixed plate. The telescopic rods are structures for telescopic extension and retraction.

[0012] In a preferred embodiment, a lifting plate is fixedly installed on the top of the telescopic rod, and a guide roller is rotatably connected to the top of the lifting plate. The guide roller is a structure used for guidance.

[0013] In a preferred embodiment, a winding box is fixedly installed on one side of the bottom of the fixing plate, and a support net is provided inside the winding box, which is a structure for support.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This rapid tunneling device for breaking up the roof uses an extraction pump to draw chemical liquid from the storage tank through an extraction pipe and send it into the diversion valve. The diversion valve then splits the liquid and sends it through two diversion pipes into the cross valve. After being split by the cross valve, the liquid is sent through three delivery pipes into the nozzle. Finally, the nozzle sprays the liquid out, thereby grouting and reinforcing the broken roof. This increases the reinforcement methods and avoids simply reinforcing the broken roof, improving the reinforcement effect. The support plate can support the broken roof, and the height can be adjusted by the lifting rod. All pipeline structures use high-pressure hose structures, which facilitates height adjustment.

[0016] 2. This rapid tunneling device for breaking up roofs can transport the support mesh through a winding box, guide the support mesh through guide rollers, and adjust the lifting plate to a suitable height by extending and retracting the telescopic rod inside the fixed plate. A drilling machine can drill holes to deepen the fixing points, facilitating the installation of rivets and reinforcing the support mesh. This allows the support mesh to effectively support the broken roof, improving the practicality and convenience of the rapid tunneling device for breaking up roofs. Attached Figure Description

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.

[0023] Combined with appendix Figure 1-4 In this embodiment, a rapid tunneling device for breaking up roof slabs includes: an extraction pump 1, an extraction pipe 11 fixedly installed on one side of the extraction pump 1, a storage tank 12 fixedly installed on one side of the extraction pipe 11, a diversion valve 13 fixedly installed on the top of the extraction pump 1, the diversion valve 13 being in a "T" shape, diversion pipes 14 fixedly installed inside both sides of the diversion valve 13, the diversion pipes 14 being in an "L" shape, a cross valve 15 fixedly installed on the top of the diversion pipes 14, the cross valve 15 being in a "+" shape, a conveying pipe 16 fixedly installed inside both sides and the top of the cross valve 15, a nozzle 17 fixedly installed on the top of the conveying pipe 16, a support plate 18 fixedly installed on the outside of the nozzle 17, and four lifting rods 19 fixedly installed around the bottom of the support plate 18.

[0024] Specifically, the diversion valve 13 is a DN65-QD-PN40 model. By operating the extraction pump 1, the liquid inside the storage tank 12 can be extracted through the extraction pipe 11 and sent into the diversion valve 13. After diversion, the liquid is sent into the cross valve 15 through two diversion pipes 14. After the liquid is diverted by the cross valve 15, it is sent into the nozzle 17 through three delivery pipes 16 and sprayed out. The height of the support plate 18 can be adjusted by operating the lifting rod 19.

[0025] A roadheader 2 is fixedly installed at the bottom of the extraction pump 1. Two support blocks 21 are fixedly installed on one side of the top of the roadheader 2. The support blocks 21 are triangular in shape. A drill bit 22 is installed in the middle of one side of the roadheader 2. Two telescopic columns 23 are fixedly installed on the right side of the top of the roadheader 2. A drilling machine 24 is fixedly installed on the top of the telescopic columns 23.

[0026] Specifically, the height of the drilling machine 24 can be adjusted by the operation of the telescopic column 23, and the drilling machine 24 can be used to drill holes, which facilitates the installation of rivets. The support block 21 can provide auxiliary support for the fixing plate 3.

[0027] A fixed plate 3 is fixedly installed on the top of one side of the roadheader 2. Two telescopic rods 31 are fixedly installed on both sides inside the fixed plate 3. A lifting plate 32 is fixedly installed on the top of the telescopic rods 31. A guide roller 33 is rotatably connected to the top of the lifting plate 32. A winding box 34 is fixedly installed on the bottom of one side of the fixed plate 3. A support net 35 is provided inside the winding box 34.

[0028] Specifically, by extending and retracting the telescopic rod 31 inside the fixed plate 3, the lifting plate 32 can be pushed upward, thereby adjusting the height of the guide roller 33, and the support net 35 can be wound up and unwound through the winding box 34.

[0029] Working principle: First, the rapid excavation device for breaking up the roof is placed in the designated position. Support block 21 provides auxiliary support for the fixed plate 3. The extension and retraction of the telescopic rods 31 on both sides inside the fixed plate 3 pushes the lifting plate 32 upwards, thereby adjusting the height of the guide roller 33. The guide roller 33 guides the support net 35, which is then released through the winding box 34. The support net 35 supports the broken roof. The extension and retraction of the telescopic column 23 pushes the drilling machine 24 to adjust its height, and the drilling machine 24 drills holes to facilitate the installation of rivets, thus fixing the support net 35. The operation of the extraction pump 1... The extraction pipe 11 extracts the chemical liquid from the storage tank 12 and sends it into the diversion valve 13. The diversion valve 13 then diverts the liquid through two diversion pipes 14 into the cross valve 15. After the cross valve 15 diverts the liquid, it is sent through three delivery pipes 16 into the nozzle 17. Finally, the nozzle 17 sprays the liquid out, thereby grouting and reinforcing the broken roof. The support plate 18 supports the broken roof, and the height of the support plate 18 can be adjusted by the lifting rod 19. The extraction pipe 11, diversion pipe 14, and delivery pipe 16 all use high-pressure hoses of type EN856-4SH, which facilitates the adjustment of the height of the support plate 18.

[0030] 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.
