Description

Technical Field

[0001] This utility model relates to the technical field of tunnel face construction equipment, and in particular to a tunnel operation vehicle. Background Technology

[0002] Traditional tunnel face construction relies on manual labor. Workers must perform long hours of strenuous physical labor at the narrow, high-altitude, damp, and poorly lit tunnel face, carrying heavy medical cartridges, using makeshift scaffolding or aerial work platforms. This work method has significant drawbacks: Extremely high safety risks: Personnel are exposed to the unsupported open space and face direct risks such as falling rocks, collapses, and falls from heights.

[0003] Low operational efficiency: Manual loading is slow, and the loading density and coupling degree are difficult to control precisely, resulting in unstable blasting effects, easy over-excavation and under-excavation, affecting the tunnel outline quality and subsequent support costs.

[0004] High labor intensity and harsh environment: After blasting, the dust and smoke concentration near the working face is high, the visibility is poor, and the noise is loud, which seriously damages the health of workers.

[0005] To address the aforementioned issues, the mechanization and automation of tunnel construction have become a clear development direction. Significant progress has been made both domestically and internationally in areas such as rock drilling rigs, shotcrete robots, and arch frame installation machines. However, the development of specialized automated equipment for the critical and high-risk process of explosive loading at the tunnel face remains relatively lagging, and the market lacks mature, reliable, and widely adaptable products.

[0006] Recently, some domestically produced mechanized equipment for tunnel face explosive loading operations has provided valuable solutions, aiming to offer a safe, reliable, and rapidly deployable and retractable working platform for personnel. This signifies that the field is actively exploring ways to reduce manual labor intensity, increase efficiency, and improve safety. However, existing technologies still need further refinement and integration to cope with the complex and ever-changing tunnel construction environment. In particular, there is a need to develop a tunnel face construction work trolley that can simultaneously adapt to both full-face single-stage excavation and micro-step staged excavation methods. This equipment needs to address the following key technology integration issues: Multi-condition adaptability: It needs to have a flexible boom and working platform to adapt to rapid positioning and stable operation in a wide full-section area as well as in the limited micro-step upper and lower spaces.

[0007] Collaborative operation: The work platform can adapt to different tunnel cross sections, and its width can be changed according to the changes in the tunnel cross section and the needs of construction personnel.

[0008] Safety and efficiency: The work trolley should provide a safe and reliable working environment for construction personnel, while also enabling rapid and convenient transfer, deployment, and retrieval within the tunnel.

[0009] Human-machine friendly and intelligent control: Equipped with an ergonomic control system and a good working environment, reducing the difficulty of operation and fatigue, and reserving data interfaces to support digital construction management.

[0010] Therefore, developing a new type of integrated, intelligent, and highly adaptable tunnel face operation trolley is not only an urgent need to overcome existing construction pain points and ensure personnel safety, but also a key link in promoting the upgrade of tunnel drilling and blasting construction to "less manpower, intelligent, and standardized" methods, achieving cost reduction, efficiency improvement, and technological progress in the industry.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1 Figures 1 to 4 as well as Figures 9 to 10 This illustration shows an embodiment of the tunnel working vehicle of the present invention. The tunnel working vehicle of this embodiment includes a vehicle body 1, a folding arm 2, and a working platform 3. A loading platform 11 is provided on the vehicle body 1. One end of the folding arm 2 is connected to the loading platform 11, and the other end is connected to the working platform 3 to adjust the height of the working platform 3 and the distance between the working platform 3 and the working face (specifically, the tunnel face in this embodiment). Preferably, a driver's cab 14 is provided at the front end of the vehicle body 1, and the loading platform 11 is located at the rear end of the vehicle body 1. The tunnel working vehicle moves to the vicinity of the tunnel face by reversing.

[0039] The tunnel work vehicle of this embodiment has a compact structure when folded, allowing for flexible relocation within tunnels. It is highly mobile and meets road traffic standards, enabling it to be moved between different tunnels. Specifically, as shown below... Figure 1 and Figure 2As shown. By extending the folding arm 2, the height of the working platform 3 and the distance between the working platform 3 and the working face can be adjusted to meet the needs of tunnel face construction such as blast hole loading, as specifically as... Figure 3 and Figure 4 As shown, no manual erection or dismantling of scaffolding platforms is required, making it convenient and efficient to use.

[0040] Furthermore, in this embodiment, the folding arm 2 includes a first swing arm 21, a first drive assembly 22 for driving the first swing arm 21 to swing up and down, a second swing arm 23, and a second drive assembly 24 for driving the second swing arm 23 to swing up and down. The loading platform 11 is provided with a longitudinally arranged slide rail 12, and a slide block 13 is provided on the slide rail 12. The first end of the first swing arm 21 is hinged to the slide block 13, the second end of the first swing arm 21 is hinged to the first end of the second swing arm 23, and the second end of the second swing arm 23 is connected to the working platform 3. By swinging the first swing arm 21 and the second swing arm 23 up and down, the height of the working platform 3 and the distance between the working platform 3 and the working surface can be conveniently and synchronously adjusted. When the height of the working platform 3 is appropriate, but the distance to the working surface is too close or too far, the distance between the working platform 3, the first swing arm 21, the second swing arm 23, and the working surface can be adjusted as a whole by sliding the slide block 13 along the slide rail 12. The structure is reasonable and effective. After the folding arm 2 is retracted, it can also be accurately placed on the loading platform 11 by sliding the slide block 13. Preferably, the first swing arm 21, the second swing arm 23, and the slide rail 12 are located on the left and right sides of the loading platform 11, which provides good symmetry and balance. Here, longitudinal refers to the front-to-back direction of the vehicle.

[0041] Furthermore, in this embodiment, the first drive assembly 22 includes a first telescopic drive member 221 (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.) and two first connecting rods 222. The first end of the first telescopic drive member 221 is hinged to the slide block 13 via one first connecting rod 222 and to the first end of the first swing arm 21 via the other first connecting rod 222. The second end of the first telescopic drive member 221 is hinged to the second end of the first swing arm 21. By extending and retracting the first telescopic drive member 221, the first swing arm 21 can be driven to swing up and down, resulting in a simple and reliable structure. The first end of the first telescopic drive member 221 is hinged to the first swing arm 21 and the slide block 13 via the first connecting rods 222, allowing the position of the first end of the first telescopic drive member 221 to change, thereby enabling the first swing arm 21 to have a larger swing angle.

[0042] Furthermore, in this embodiment, the second drive assembly 24 includes a second telescopic drive member 241 (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.) and two second connecting rods 242. The first end of the second telescopic drive member 241 is hinged to the first end of the first swing arm 21, and the second end of the second telescopic drive member 241 is hinged to the second end of the first swing arm 21 via one second connecting rod 242 and to the first end of the second swing arm 23 via the other second connecting rod 242. By extending and retracting the second telescopic drive member 241, the second swing arm 23 can be driven to swing relative to the first swing arm 21, resulting in a simple and reliable structure. The second end of the second telescopic drive member 241 is hinged to the first end of the second swing arm 23 and the second end of the first swing arm 21 via the second connecting rods 242, allowing the position of the second end of the second telescopic drive member 241 to change, thereby enabling the second swing arm 23 to have a larger swing angle.

[0043] Furthermore, in this embodiment, the end of the folding arm 2 near the working platform 3 is provided with a rotating platform 4 and a rotation drive component 41 for driving the rotating platform 4 to rotate. The working platform 3 is mounted on the rotating platform 4 (specifically, the platform body 33 of the working platform 3 is mounted on the rotating platform 4). The working platform 3 is integrated and installed on the rotating platform 4 with rotation function. During transfer, the working platform 3 is arranged in the front-to-back direction to avoid its width exceeding the width of the loading platform 11 itself, specifically as follows... Figure 1 and Figure 2 As shown. In use, the rotating platform 4 rotates 90°, and the working platform 3 is arranged along the left-right direction, specifically as follows: Figure 3 and Figure 4 As shown, this design allows the work platform 3 to be longer within the same vehicle length, and after rotation, it can cover a larger working area on the working face, resulting in a reasonable and effective structure. Preferably, the folding arm 2 extends after the work platform 3 is rotated to a position along the left-right direction.

[0044] Furthermore, in this embodiment, the work platform 3 includes a first work platform 31 and a second work platform 32. Workers can simultaneously work on both platforms, improving work efficiency. The rotating platform 4 is equipped with an adjusting guide rail 43 and an adjusting drive component 42 (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). The first work platform 31 and / or the second work platform 32 are mounted on the adjusting guide rail 43 and connected to the adjusting drive component 42 to adjust the distance between them. During relocation, the first work platform 31 and the second work platform 32 move closer together, fully utilizing the space in the width direction of the loading platform 11. During operation, the adjusting drive component 42 drives the first work platform 31 and / or the second work platform 32 to move along the adjusting guide rail 241, thereby increasing the distance between them, facilitating operation, and resulting in a reasonable and effective structure.

[0045] In this embodiment, the rotating platform 4 is mounted on a swing seat 5, and the folding arm 2 is equipped with a third drive assembly 25 (e.g., a cylinder, hydraulic cylinder, etc., which drives the swing seat 5 to swing up and down by extension and retraction) for driving the swing seat 5 to swing up and down. During transport, the swing seat 5 and the rotating platform 4 are in a horizontal state; when used for operation, the third drive assembly 25 drives the swing seat 5 to swing to a vertical state, and the rotating platform 4 swings to a vertical state along with the swing seat 5, making it convenient for operators to work on the work platform 3.

[0046] See details Figure 9 In this embodiment, the rotating platform 4 is hinged to the swing seat 5, and the rotating drive component 41 is a telescopic structure (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). One end of the rotating drive component 41 is hinged to the rotating platform 4, and the other end is hinged to the swing seat 5. By extending and retracting the rotating drive component 41, the rotating platform 4 can be driven to rotate relative to the swing seat 5. The structure is simple and has good reliability.

[0047] See details Figure 10 In this embodiment, the working platform 3 includes a platform body 33 and retractable platforms 34 located at both ends of the platform body 33 (for example, the retractable platforms 34 are driven to slide relative to the platform body 33 by retractable drive components such as cylinders and hydraulic cylinders). The working platform 3 can be extended and retracted according to the width of the working face, thereby achieving the effect of full coverage of the working face.

[0048] Example 2 Figures 5 to 8 Another embodiment of the tunnel working vehicle of this utility model is shown. The tunnel working vehicle of this embodiment is basically the same as that of embodiment one, except that: In this embodiment, the swing seat 5 is mounted on a lifting bracket 51, which is hinged to the folding arm 2. The third drive assembly 25 is a telescopic structure, with one end hinged to the folding arm 2 and the other end hinged to the lifting bracket 51. The lifting bracket 51 is equipped with a lifting drive assembly 52 (e.g., a cylinder, hydraulic cylinder, or screw and nut mechanism) for driving the swing seat 5 to move up and down. By extending and retracting the third drive assembly 25, the lifting bracket 51 can be driven to swing to a vertical position, and the swing seat 5 swings to a vertical position along with the lifting bracket 51. When the distance between the working platform 3 and the working surface is appropriate, but the height needs to be adjusted, the swing seat 5 can be driven to move up and down along the lifting bracket 51 by the lifting drive assembly 52. ​​The rotating platform 4 and the working platform 3 move up and down as a whole with the swing seat 5. In the retracted state, the front and rear positions of the working platform 3 can also be adjusted. The structure is reasonable and effective.
