Description

Technical Field

[0001] This utility model relates to the field of coal mine tunneling technology, and in particular to coal mine tunneling mechanisms. Background Technology

[0002] Coal mine tunneling mechanisms are core equipment specifically designed for underground roadway excavation operations in coal mines. Their core function is to achieve the shaping and excavation of roadway cross-sections and the advancement of the working face through the integrated and coordinated operation of rock breaking, rock loading, and rock transportation in coal mining scenarios. At the same time, they are adapted to the complex geological conditions and safety regulations of underground coal mines, and build smooth operating channels for subsequent coal mining, ventilation, transportation and other processes, ensuring the continuous and efficient operation of the coal mining process.

[0003] Existing technologies cannot settle airborne dust during coal mine tunneling, nor can they cool the tunnel head. This not only makes the tunnel head prone to damage but also generates sparks, posing safety hazards.

[0004] An existing patent (publication number: CN220015167U) discloses a coal mine tunneling mechanism, specifically relating to the field of coal mine tunneling technology. It includes an installation mechanism comprising a tunneling machine body, a mounting side plate at the bottom of the tunneling machine body, tracks between the mounting side plates, a protective mechanism on the upper surface of the tunneling machine body, and a tunneling mechanism on the side of the tunneling machine body. The protective mechanism includes a settling component, a dust extraction component, a fixing plate, and a protective plate. The fixing plate is located at the top of the tunneling mechanism, and the protective plate is located at the top of the tunneling machine body. This invention can settle airborne dust and cool the tunnel head, preventing sparks from excessive heat and reducing safety hazards. It can also extract and absorb dust, preventing harmful substances from affecting the health of workers, and provides protection for the tunnel head, extending its service life and improving the practicality of the device.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing coal mine tunneling mechanisms have limited dust suppression coverage with their associated dust suppression devices, making it difficult to intercept and suppress the spread of dust generated during tunneling from multiple directions. This leads to dust concentrations in the working environment easily exceeding standards. Furthermore, the connection structure between the conveying pipelines of most dust suppression devices and the tunneling mechanism is complex, and the assembly and disassembly processes are cumbersome. Once the pipelines suffer wear, cracks, or other damage, a significant amount of time must be spent on disassembly and repair, extending equipment downtime and making it inconvenient for users.

[0006] Therefore, a coal mine tunneling mechanism is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a coal mine tunneling mechanism that can solve the problems of existing coal mine tunneling mechanism dust suppression devices, which have limited dust suppression coverage and cannot intercept dust diffusion in multiple directions, easily leading to excessive dust concentration in the working environment. At the same time, the connection between the conveying pipeline and the tunneling mechanism is complicated, disassembly and assembly are cumbersome, and repairs after pipeline damage are time-consuming, equipment downtime is long, and operation is inconvenient.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a coal mine tunneling mechanism, including a tunneling machine structure, a first mounting frame is provided on the surface of the tunneling machine structure, a clamp is provided on the surface of the first mounting frame, a connecting pipe is clamped to the inner wall of the clamp, a spraying mechanism is provided on the surface of the connecting pipe, a booster pump is provided on the left side of the tunneling machine structure, the spraying mechanism includes a main spray head, a connecting component is movably connected to the left side of the main spray head, the connecting component is provided on the surface of the connecting pipe, and a reinforcing spray head is movably connected to the surface of the connecting component.

[0009] Preferably, the inner wall of the first mounting bracket is rotatably connected to a rotating shaft, and a rotating block is fixedly connected to the surface of the rotating shaft. The surface of the rotating block is movably connected to the inner wall of the first mounting bracket.

[0010] Preferably, a second mounting bracket is fixedly connected to the rear side of the rotating block, and the inner wall of the second mounting bracket is movably connected to the surface of the tunneling machine structure.

[0011] Preferably, the bottom of the first mounting bracket is fixedly connected to a first fixing plate, and the bottom of the second mounting bracket is fixedly connected to a second fixing plate.

[0012] Preferably, a knob is movably connected to the inner wall of the first fixing plate, and the surface of the knob is threadedly connected to the inner wall of the second fixing plate.

[0013] Preferably, a fixing block is fixedly connected to the surface of the first mounting bracket, and the fixing block is fixedly connected to the bracket on the side near the bracket.

[0014] Preferably, the top of the booster pump is movably connected to a transmission pipe, the surface of the transmission pipe is movably connected to the inner wall of the tunneling machine structure, and the side of the transmission pipe near the connecting pipe is movably connected to the connecting pipe.

[0015] Preferably, the inner wall of the card holder is provided with a fixing groove for use with the connecting pipe, and the inner wall of the first mounting bracket is provided with a rotating hole for use with the rotating shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application provides a spraying mechanism that, through the coordinated design of the main spray head, connecting components, and reinforced spray heads, provides a highly efficient dust suppression function for small tunneling machine structures. The connecting components ensure stable connection between the main spray head, reinforced spray heads, and connecting pipes, ensuring that the dust suppression medium (such as water) delivered by the booster pump can be smoothly distributed to each spraying component. The main spray head and reinforced spray heads form a multi-dimensional spray coverage area, which can act on the dust source and diffusion path generated during the operation of the tunneling machine structure, thereby improving dust suppression efficiency.

[0018] 2. This application establishes a first mounting bracket, whose surface clips enable rapid assembly of the connecting pipe via a snap-fit ​​mechanism. The multi-clip limit design significantly enhances the structural stability of the connecting pipe after installation, effectively preventing loosening or detachment during tunneling machine vibration operations, thus ensuring the continuity of dust suppression spraying. The snap-fit ​​connection between the connecting pipe and the clips allows for convenient disassembly of the connecting pipe. When the connecting pipe is damaged, it can be disassembled and replaced without complex tools, shortening equipment maintenance time and reducing maintenance costs. The booster pump provides stable pressure power to the entire spraying structure, ensuring that the dust suppression medium is delivered to the spraying mechanism at sufficient pressure.

A clamping frame 4 is provided on the surface of the first mounting frame 3. A connecting pipe 5 is clamped to the inner wall of the clamping frame 4.

The spraying mechanism 2 includes a main spray head 201. A connecting component 202 is movably connected to the left side of the main spray head 201. The connecting component 202 is provided on the surface of the connecting pipe 5. A reinforcing spray head 203 is movably connected to the surface of the connecting component 202.

[0028] In this embodiment: By setting up the spraying mechanism 2, the main spray head 201, connecting component 202, and reinforcing spray head 203 work together to provide efficient dust suppression for the small tunneling machine structure 1. The connecting component 202 ensures stable connection between the main spray head 201, the reinforcing spray head 203, and the connecting pipe 5, ensuring that the dust suppression medium (such as water) delivered by the booster pump 6 can be smoothly distributed to each spraying component. The main spray head 201 and the reinforcing spray head 203 form a multi-dimensional spray coverage area, which can act on the dust source and diffusion path generated during the operation of the tunneling machine structure 1, improving dust suppression efficiency. The first mounting bracket 3 has a clip 4 on its surface that enables the rapid assembly of the connecting pipe 5 through a snap-fit ​​mechanism. The limiting design of the multiple clips 4 greatly enhances the structural stability of the connecting pipe 5 after installation, effectively preventing it from loosening or falling off during the vibration operation of the tunneling machine structure 1, thus ensuring the continuity of the dust suppression spraying operation. The snap-fit ​​cooperation between the connecting pipe 5 and the clip 4 allows the connecting pipe 5 to be easily disassembled. When the connecting pipe 5 is damaged, it can be disassembled and replaced without complicated tools, shortening equipment maintenance time and reducing maintenance costs. The booster pump 6 provides stable pressure power for the entire spraying structure, ensuring that the dust suppression medium is delivered to the spraying mechanism 2 at sufficient pressure.

[0029] Specifically, such as Figure 4 As shown, a rotating shaft 7 is rotatably connected to the inner wall of the first mounting bracket 3, and a rotating block 8 is fixedly connected to the surface of the rotating shaft 7.

[0030] Specifically, such as Figure 4As shown, a second mounting bracket 9 is fixedly connected to the rear side of the rotating block 8, and the inner wall of the second mounting bracket 9 is movably connected to the surface of the tunneling machine structure 1.

[0031] Specifically, such as Figure 5 As shown, the bottom of the first mounting bracket 3 is fixedly connected to a first fixing plate 10, and the bottom of the second mounting bracket 9 is fixedly connected to a second fixing plate 11.

[0032] In this embodiment: By setting up a rotating block 8, a rotating shaft 7, and a second mounting bracket 9, the second mounting bracket 9 is fixed to the position of the rotating block 8 and the rotating block 8 to the position of the rotating shaft 7 during use, which facilitates the subsequent rotation of the first mounting bracket 3 on the surface of the rotating shaft 7 and facilitates the flexible assembly and disassembly of the first mounting bracket 3 and the second mounting bracket 9. By setting up a first fixing plate 10 and a second fixing plate 11, the first fixing plate 10 is fixed to the position of the first mounting bracket 3 and the second fixing plate 11 is fixed to the position of the second mounting bracket 9 during use, which facilitates the subsequent auxiliary limiting work through the first fixing plate 10 and the second fixing plate 11, and facilitates the rapid installation of the first mounting bracket 3 and the second mounting bracket 9.

[0033] Specifically, such as Figure 5 As shown, a knob 12 is movably connected to the inner wall of the first fixing plate 10, and the surface of the knob 12 is threadedly connected to the inner wall of the second fixing plate 11.

[0034] Specifically, such as Figure 5 As shown, a fixing block 13 is fixedly connected to the surface of the first mounting bracket 3, and the side of the fixing block 13 near the card holder 4 is fixedly connected to the card holder 4.

[0035] In this embodiment: By setting the knob 12, the first mounting bracket 3 and the second mounting bracket 9 can be quickly locked or unlocked by rotating the knob 12 on the inner wall of the first fixing plate 10 and the second fixing plate 11. The operation is convenient and the locking effect is stable. By setting the fixing block 13, the first mounting bracket 3 is fixed by the position of the fixing block 13, which facilitates the stable fixing of the clamping bracket 4 by the fixing block 13. This prevents the clamping bracket 4 from loosening or deforming during the vibration of the tunneling machine structure 1 or the assembly and disassembly of the connecting pipe 5, and ensures the stability of the connecting pipe 5 after it is clamped.

[0036] Specifically, such as Figure 2 As shown, the top of the booster pump 6 is movably connected to the transmission pipe 14, the surface of the transmission pipe 14 is movably connected to the inner wall of the tunneling machine structure 1, and the side of the transmission pipe 14 near the connecting pipe 5 is movably connected to the connecting pipe 5.

The connecting pipe 5 is installed on the inner wall of the card holder 4 through the fixing groove 15. The rotating shaft 7 is rotated through the rotating hole 16 on the inner wall of the first mounting bracket 3.

[0039] Working Principle: During the use of the tunneling machine structure 1, the spraying mechanism 2, through the coordinated design of the main spray head 201, connecting component 202, and reinforcing spray head 203, provides efficient dust suppression for the small tunneling machine structure 1. The connecting component 202 ensures stable connection between the main spray head 201, reinforcing spray head 203, and connecting pipe 5, ensuring that the dust suppression medium (such as water) delivered by the booster pump 6 can be smoothly distributed to each spraying component. The main spray head 201 and reinforcing spray head 203 form a multi-dimensional spray coverage area, which can act on the dust source and diffusion path generated during the operation of the tunneling machine structure 1, improving dust suppression efficiency. The first mounting bracket 3 is set up, and the clips 4 on the surface of the first mounting bracket 3 enable the rapid assembly of the connecting pipe 5 through a snap-fit ​​method. The limiting design of the multiple clips 4 greatly enhances the structural stability of the connecting pipe 5 after installation, effectively preventing it from loosening or falling off during the vibration operation of the tunneling machine structure 1, ensuring the continuity of the dust suppression spraying work. The snap-fit ​​cooperation between the connecting pipe 5 and the clips 4 enables the connecting pipe 5 to be easily disassembled. When the connecting pipe 5 is damaged, it can be disassembled and replaced without complicated tools, shortening equipment maintenance time and reducing maintenance costs. The booster pump 6 provides stable pressure power for the entire spraying structure, ensuring that the dust suppression medium is delivered to the spraying mechanism 2 at sufficient pressure.
