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 and fatigue of operation, 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.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Figures 1 to 8 This illustration shows an embodiment of the tunnel boring machine (TBM) of this invention. The TBM includes a vehicle body 1, a swing bracket 2, and a working platform 3. The vehicle body 1 has a loading platform 11, and the swing bracket 2 is hinged to the loading platform 11. The loading platform 11 has a swing drive component 12 for driving the swing bracket 2 to swing up and down. The swing bracket 2 has a first lifting guide rail 211 and a second lifting guide rail 212. The first lifting guide rail 211 has a first lifting seat 213, and the second lifting guide rail 212 has a second lifting seat 214. The working platform 3 includes a first working platform 31 mounted on the first lifting seat 213 and a second working platform 32 mounted on the second lifting seat 214. See details below. Figures 3 to 5 Preferably, the front end of the vehicle body 1 is provided with a driver's cab 15, the loading platform 11 is provided at the rear end of the vehicle body 1, the rear end of the swing bracket 2 is hinged to the rear end of the loading platform 11, and the left and right sides of the swing bracket 2 are provided with swing drive components 12, which have good symmetry and balance.

[0036] The tunnel boring machine equipment 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 As shown. The loading platform 11 integrates a swing bracket 2, a first lifting seat 213, a second lifting seat 214, a first working platform 31, and a second working platform 32. After the swing bracket 2 swings to the vertical position (specifically as shown in the figure), Figure 3As shown), the first lifting seat 213 and the second lifting seat 214 can move independently along the first lifting guide rail 211 and the second lifting guide rail 212 (for example, driven by a hydraulic cylinder, screw and nut mechanism, gear and rack mechanism, or commercially available lifting machine, etc.), thereby driving the first working platform 31 and the second working platform 32 to rise and fall. The height of the first working platform 31 and the second working platform 32 can be adjusted to meet the construction needs of blast hole loading (specifically as shown). Figure 6 and Figure 7 As shown in the figure, no manual erection or dismantling of scaffolding platforms is required, making it convenient and efficient to use.

[0037] Furthermore, in this embodiment, the first lifting seat 213 is provided with a first rotating platform 24 and a rotating drive component 25 for driving the first rotating platform 24 to rotate. The first working platform 31 is disposed on the first rotating platform 24 (specifically, the platform body 33 of the first working platform 31 is disposed on the first rotating platform 24). The first working platform 31 is integrated and installed on the first rotating platform 24 with rotating function. During transfer, the first working platform 31 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 As shown. In use, the first rotating platform 24 rotates 90°, and the first working platform 31 is arranged in the left-right direction, as shown in the figure. Figure 3 As shown, this allows the first working platform 31 to be designed to be longer within the same vehicle body length, and after rotation, it can cover a larger working area on the working face, making the structure reasonable and effective.

[0038] See details Figure 8 In this embodiment, the first rotating platform 24 is hinged to the first lifting seat 213, and the first rotating drive component 25 is a telescopic structure (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). One end of the first rotating drive component 25 is hinged to the first rotating platform 24, and the other end is hinged to the first lifting seat 213. The first rotating platform 24 can be driven to rotate relative to the first lifting seat 213 by the extension and retraction of the first rotating drive component 25. The structure is simple and has good reliability. Of course, in other embodiments, the first rotating drive component 25 can also drive the rotating platform 24 to rotate via a motor, hydraulic motor, etc., which will not be elaborated further.

[0039] Furthermore, in this embodiment, the first rotating platform 24 is provided with a rotating arm 241, and the first lifting seat 213 is provided with a first limiting part 231 and a second limiting part 232. The rotating arm 241 is located between the first limiting part 231 and the second limiting part 232. When the rotating arm 241 rotates with the first rotating platform 24 and contacts the first limiting part 231 or the second limiting part 232, it indicates that the first rotating platform 24 has rotated to its maximum angle (90° in this embodiment) or has completed its reset, which is helpful in determining the rotation angle of the first rotating platform 24.

[0040] The rotating structure of the second working platform 32 is the same as that of the first working platform 31, and will not be described again.

[0041] See details Figure 6 and Figure 7 In this embodiment, both the first working platform 31 and the second working platform 32 include 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 a retractable driving component such as a cylinder). The first working platform 31 and the second working platform 32 can be extended and retracted according to the width of the working face, thereby achieving the effect of full coverage in the width direction of the working face.

[0042] See details Figures 6 to 7 In this embodiment, the swing drive 12 is a telescopic structure (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). One end of the swing drive 12 is hinged to the loading platform 11, and the other end is hinged to the swing bracket 2. By extending and retracting the swing drive 12, the swing bracket 2 can be driven to swing up and down, realizing the switching between the horizontal and vertical states of the swing bracket 2. The structure is simple and reliable.

[0043] Furthermore, in this embodiment, the vehicle body 1 is provided with telescopic beams 13 that can extend and retract in the left and right directions on both sides, and the telescopic beams 13 are provided with telescopic outriggers 14 that can extend and retract in the vertical direction. Before the tunnel working vehicle enters the working state, the telescopic beams 13 drive the telescopic outriggers 14 to extend to the left and right sides, and then the telescopic outriggers 14 extend downward to contact the bottom surface of the tunnel, which can provide stable support for the vehicle body 1 and prevent overturning.

[0044] The method of using this utility model tunnel working vehicle is as follows: 1) Specifically, as follows Figure 1 and Figure 2 As shown, the tunnel working vehicle equipment is in the retracted state and reverses to the vicinity of the tunnel face. Then, the telescopic beam 13 drives the telescopic outriggers 14 to extend to the left and right sides. The telescopic outriggers 14 extend downward to contact the bottom of the tunnel, adjusting the vehicle body 1 to a horizontal state and providing stable support for the vehicle body 1. 2) Specifically, as follows Figure 3 As shown, the first rotating platform 24 and the second rotating platform are rotated 90°, so that the two-stage working platform 3 is changed from being placed front and back to being placed side to side; 3) Specifically, as follows Figure 4 As shown, the swing bracket 2 swings upward to a vertical position; 4) Specifically, as follows Figure 5 As shown, the lower second lifting platform 214 descends to a low position along the second lifting guide rail 212, thereby increasing the distance between the first working platform 31 and the second working platform 32. 5) Specifically, as follows Figures 5 to 7As shown, the first working platform 31 and the second working platform 32 gradually rise to complete the construction work of the entire working face; during the operation, the extension and retraction of the telescopic platform 34 are adjusted according to the actual width of the working face.

[0045] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
