Description

Technical Field

[0001] This invention relates to the field of tunnel face construction equipment technology, and in particular to a tunnel working 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. Summary of the Invention

[0014] As a further improvement to the above technical solution: the rotating platform is hinged to the lifting seat, the rotating drive component is a telescopic structure, one end of the rotating drive component is hinged to the rotating platform, and the other end is hinged to the lifting seat.

[0015] As a further improvement to the above technical solution: the rotating platform is provided with a rotating arm, the lifting seat is provided with a first limiting part and a second limiting part, and the rotating arm is located between the first limiting part and the second limiting part.

[0016] As a further improvement to the above technical solution: the working platform includes a first working platform and a second working platform, and the distance between the first working platform and the second working platform is adjustable.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Figures 1 to 9 An embodiment of the tunnel working vehicle of the present invention is shown. This embodiment of the tunnel working vehicle includes a vehicle body 1, a swing bracket 2, and a working platform 3. A loading platform 11 is provided on the vehicle body 1. The swing bracket 2 is hinged to the loading platform 11. A swing drive component 12 for driving the swing bracket 2 to swing up and down is provided on the loading platform 11. A lifting guide rail 21 is provided on the swing bracket 2, and a lifting seat 23 is provided on the lifting guide rail 21. The working platform 3 is located on the lifting seat 23. See details. 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 lifting guide rails 21 and swing drive components 12, which have good symmetry and balance.

[0037] 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 As shown. The loading platform 11 integrates a swing bracket 2, a lifting seat 23, and a working platform 3. After the swing bracket 2 swings to the vertical position (specifically as shown in the figure), Figure 3 As shown), the lifting seat 23 can move along the lifting guide rail 21 (for example, by a hydraulic cylinder, screw and nut mechanism, gear and rack mechanism, or commercially available lifting machine, etc. to drive the lifting seat 23 to rise and fall), thereby driving the working platform 3 to rise and fall. The height of the working platform 3 can be adjusted to meet the construction needs of loading explosives into blast holes (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.

[0038] Furthermore, in this embodiment, the lifting seat 23 is provided with a rotating platform 24 and a rotation drive component 25 for driving the rotating platform 24 to rotate. The working platform 3 is disposed on the rotating platform 24 (specifically, the platform body 33 of the working platform 3 is disposed on the rotating platform 24). The working platform 3 is integrated and installed on the rotating platform 24 with rotation function. During relocation, 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 As shown. In use, the rotating platform 24 rotates 90°, and the working platform 3 is arranged along the left-right direction, specifically as follows: Figure 2 As shown, this allows the work platform 3 to be designed to be longer within the same vehicle length, and after rotation, it can cover a larger working area on the working face, making the structure reasonable and effective.

[0039] See details Figure 9 In this embodiment, the rotating platform 24 is provided with an adjusting guide rail 241 and an adjusting drive component 242 (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). The adjusting guide rail 241 is provided with an adjusting seat 243, and the adjusting drive component 242 is connected to the adjusting seat 243. The working platform 3 includes a first working platform 31 disposed on the adjusting seat 243 and a second working platform 32 fixedly disposed on the rotating platform 24. During relocation, the first working platform 31 and the second working platform 32 move closer to each other, making full use of the space in the width direction of the loading platform 11. In use, the adjusting drive component 242 drives the adjusting seat 243 to move along the adjusting guide rail 241, and the first working platform 31 moves with the adjusting seat 243, thereby increasing the distance between the first working platform 31 and the second working platform 32, so that the operator can work on the first working platform 31 and the second working platform 32 at the same time. The structure is reasonable and effective. Of course, in other embodiments, the distance between the first working platform 31 and the second working platform 32 can also be adjusted in other ways (for example, the first working platform 31 and the second working platform 32 are both set on the adjusting guide rail 241, and the two are driven to move closer or further apart by cylinders, oil cylinders, etc.), which will not be elaborated further.

[0040] See details Figure 8 In this embodiment, the rotating platform 24 is hinged to the lifting seat 23, and the rotating drive component 25 is a telescopic structure (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). One end of the rotating drive component 25 is hinged to the rotating platform 24, and the other end is hinged to the lifting seat 23. The rotating platform 24 can be driven to rotate relative to the lifting seat 23 by the extension and retraction of the rotating drive component 25. The structure is simple and has good reliability. Of course, in other embodiments, the 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.

[0041] Furthermore, in this embodiment, the rotating platform 24 is provided with a rotating arm 244, and the lifting seat 23 is provided with a first limiting part 231 and a second limiting part 232. The rotating arm 244 is located between the first limiting part 231 and the second limiting part 232. When the rotating arm 244 rotates with the rotating platform 24 and contacts the first limiting part 231 or the second limiting part 232, it indicates that the 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 rotating platform 24.

[0042] 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 working platform 3 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.

[0043] See details Figures 3 to 5 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.

[0044] 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, adjusting the vehicle body 1 to a horizontal state, while providing stable support for the vehicle body 1 to prevent overturning.

[0045] The method of using the tunnel working vehicle of this invention is as follows: 1) Specifically, as follows Figure 1 As shown, the tunnel work vehicle is in the retracted state and has moved to the vicinity of the tunnel face; 2) Specifically, as follows Figure 2 As shown, the rotating platform 24 rotates 90°, so that the two-stage working platform 3 changes from being placed front and back to being placed side to side; 3) Specifically, as follows Figure 3 As shown, 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 tunnel floor, providing stable support for the vehicle body 1. Then the swing bracket 2 swings upward to a vertical position. 4) Specifically, as follows Figure 4As shown, the adjusting drive 242 drives the adjusting seat 243 to move downward along the adjusting guide rail 241, thereby increasing the distance between the first working platform 31 and the second working platform 32. 5) Specifically, as follows Figures 5 to 7 As shown, the lifting platform 23 descends to a low position along the lifting guide rail 21, and then gradually rises to complete the construction work of the entire working face; during the operation, the extension and retraction of the telescopic platform 34 is adjusted according to the actual width of the working face.

[0046] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them 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 scope of the present invention, should fall within the protection scope of the present invention.
