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.

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

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1 Figures 1 to 9This invention illustrates an embodiment of the tunnel boring machine (TBM) of the present invention. The TBM includes a vehicle body 1, a swing support 2, and a working platform 3. The vehicle body 1 is equipped with a lifting platform 11, and the lifting platform 11 has a telescopic platform 12 that can extend and retract forward and backward. The telescopic platform 12 has a movable seat 13 that can move forward and backward along the telescopic platform 12. The swing support 2 is hinged to the movable seat 13, and the movable seat 13 has a swing drive component 131 for driving the swing support 2 to swing up and down. The working platform 3 is mounted on the swing support 2. Preferably, a driver's cab 15 is located at the front end of the vehicle body 1, and the lifting platform 11 is located at the rear end of the vehicle body 1. The lifting platform 11 is equipped with guide rails, guide grooves, and other guiding structures. The telescopic platform 12 is equipped with rollers, sliders, etc., that cooperate with the guide rails and guide grooves to ensure smooth extension and retraction of the telescopic platform 12 and prevent deviation. Specifically, the telescopic platform 12 can be driven to reciprocate by cylinders, hydraulic cylinders, electric push rods, screw and nut mechanisms, etc. The movable seat 13 moves forward and backward along the telescopic platform 12 in a similar manner to the telescopic platform 12, and will not be described further.

[0046] Preferably, in this embodiment, the left and right sides of the rear end of the telescopic platform 12 are provided with first telescopic beams 121 that can extend and retract left and right, and the first telescopic beams 121 are provided with first telescopic outriggers 122 that can extend and retract vertically. The left and right sides of the vehicle body 1 are provided with second telescopic beams 14 that can extend and retract left and right, and the second telescopic beams 14 are provided with second telescopic outriggers 141 that can extend and retract vertically. See details. Figure 2 and Figure 3 Before the tunnel working vehicle enters the working state, the second telescopic beam 14 drives the first telescopic outrigger 141 to extend to the left and right sides. Then, the second telescopic outrigger 114 extends downward to contact the tunnel floor, adjusting the vehicle body 1 to a level position and providing stable support for the vehicle body 1 to prevent overturning. See details. Figure 4 After the rear end of the telescopic platform 12 extends above the step, the first telescopic beam 121 drives the first telescopic support leg 122 to extend to both sides of the work area. Then the first telescopic support leg 122 extends downward to contact the surface of the step, which can provide good support for the telescopic platform 12 so that the movable seat 13, the swing bracket 2 and the work platform 3 can pass on the telescopic platform 12.

[0047] The tunnel working vehicle equipment in this embodiment, when retracted (specifically as follows): Figure 1 (As shown) The structure is compact, allowing for flexible relocation within tunnels, high mobility, and compliance with road traffic standards, enabling relocation between different tunnels. The lifting platform 11 integrates a telescopic platform 12, a movable seat 13, a swing bracket 2, and a working platform 3. The telescopic platform 12 is first lifted to a height higher than the tunnel face (specifically as shown). Figure 3 As shown), then extend backwards to the top of the steps (specifically as shown). Figure 4 As shown), the movable seat 13 moves along the telescopic platform 12 to above the steps (specifically as shown). Figure 5As shown), finally, the swing bracket 2 swings upward (specifically as shown). Figure 7 As shown in the figure, the swing angle 2 in this embodiment is greater than 90°. The working platform 3 is close to the working face to meet the needs of tunnel construction such as loading explosives into blast holes. There is no need to manually erect or dismantle scaffolding platforms, making it convenient and efficient to use.

[0048] Furthermore, in this embodiment, the swing bracket 2 is provided with a lifting guide rail 21 and a lifting drive assembly 22 (such as a lead screw and nut mechanism, a gear and rack mechanism, a sprocket and chain mechanism, etc.). The lifting guide rail 21 is provided with a lifting seat 23, and the working platform 3 is disposed on the lifting seat 23. The lifting drive assembly 22 is connected to the lifting seat 23. Under the drive of the lifting drive assembly 22, the lifting seat 23 can move along the lifting guide rail 21, thereby driving the working platform 3 to rise and fall. The height of the working platform 3 can be adjusted to achieve full coverage of the working face in the height direction.

[0049] Furthermore, in this embodiment, the lifting platform 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 main platform 36 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 vehicle body 1 itself, specifically as follows: Figure 1 and Figure 2 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 6 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 in the left and right directions of the working face, making the structure reasonable and effective.

[0050] See details Figure 9 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. By extending and retracting the rotating drive component 25, the rotating platform 24 can be driven to rotate relative to the lifting seat 23. The structure is simple and has good reliability.

[0051] Furthermore, in this embodiment, the work platform 3 includes a first work platform 31 and a second work platform 32. Providing two levels of work platforms for workers improves work efficiency. The distance between the first work platform 31 and the second work platform 32 is adjustable. Preferably, an adjusting guide rail and an adjusting drive component (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.) can be provided on the rotating platform 24. The adjusting guide rail is arranged parallel to the lifting guide rail 21. The first work platform 31 and / or the second work platform 32 are mounted on the adjusting guide rail and moved along it by the adjusting drive component. During relocation, the first work platform 31 and the second work platform 32 move closer together, making full use of the space in the width direction of the vehicle body 1. When used for work, the distance between the first work platform 31 and the second work platform 32 is increased by adjusting the drive component, allowing workers to work simultaneously on both platforms. The structure is reasonable and effective.

[0052] Furthermore, in this embodiment, both the first working platform 31 and the second working platform 32 include a main platform 36, and both ends of the main platform 36 are provided with sliding platforms 37 that can slide left and right (for example, the sliding platforms 37 are driven to slide relative to the main platform 36 by telescopic driving components such as 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 in the width direction of the working face.

[0053] Furthermore, in this embodiment, the swing drive 131 is a telescopic structure, with one end of the swing drive 131 hinged to the movable seat 13 and the other end hinged to the swing bracket 2, specifically as follows: Figure 8 As shown. By extending and retracting the swing drive component 131, the swing bracket 2 can be driven to swing up and down, realizing the switching between the horizontal retracted state and the tilted operation state of the swing bracket 2. The structure is simple and reliable. Preferably, the rear end of the swing bracket 2 is hinged to the rear end of the lifting platform 11. The left and right sides of the telescopic platform 11 are provided with swing drive components 131, which has good symmetry and balance and can provide sufficient driving force for the swing bracket 2.

[0054] The method of using the tunnel boring machine equipment in this embodiment is as follows: 1) Specifically, as follows Figure 1 and 2 As shown, the tunnel working vehicle equipment is in the retracted state and travels to the vicinity of the tunnel face. Then, the second telescopic beam 14 drives the second telescopic outrigger 141 to extend to the left and right sides, and the second telescopic outrigger 114 extends downward to contact the bottom of the tunnel, adjusting the vehicle body 1 to a horizontal state. 2) Specifically, as follows Figure 3 As shown, the lifting platform 11 lifts the telescopic platform 12 and the rest of the platform upwards, so that the height of the telescopic platform 12 is greater than the top surface of the step. 3) Specifically, as follows Figure 4As shown, the rear end of the telescopic platform 12 extends above the step, and the first telescopic beam 121 drives the first telescopic support leg 122 to extend to both sides of the work area. Then the first telescopic support leg 122 extends downward to contact the surface of the step, providing support for the telescopic platform 12. 4) Specifically, as follows Figure 5 As shown, the movable seat 13 drives the swing bracket 2 and the working platform 3 to move backward until the rear end of the movable seat 13 reaches above the step; 5) Specifically, as follows Figure 6 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; 6) Specifically, as follows Figure 7 As shown, the swing drive 131 drives the swing bracket 2 to swing upward to the working state; 7) Specifically, as follows Figure 9 As shown, the sliding platform 37 extends to the left and right sides according to the actual width of the working face, and the lifting seat 23 drives the two-stage working platform 3 to rise gradually to complete the construction work of the entire working face.

[0055] For tunnels excavated in a single, full-section manner, where there are no steps ahead of the tunnel face, steps 2 through 4 above are unnecessary. The tunnel boring machine is in its retracted state and travels to the vicinity of the tunnel face. Then, the first telescopic beam 14 drives the first telescopic outriggers 141 to extend to the left and right sides, and the first telescopic outriggers 114 extend downwards to contact the tunnel floor, adjusting the vehicle body 1 to a level position. See details. Figure 10 Then, the rotating platform 24 rotates 90°, changing the two-stage working platform 3 from a front-to-back arrangement to a left-to-right arrangement; see details. Figure 11 The swing drive component 131 drives the swing bracket 2 to swing upward to the working state. See details. Figure 12 The sliding platform 37 extends to the left and right sides according to the actual width of the working face, and the lifting seat 23 drives the two-stage working platform 3 to rise gradually to complete the loading operation of the entire working face.

[0056] Example 2 Figures 13 to 16 This invention illustrates another embodiment of the tunnel working vehicle equipment. This embodiment is essentially the same as that in Embodiment 1, except that: In this embodiment, the working platform 3 is located on the left and right sides of the swing bracket 2 and hinged to the lifting seat 23. The working platform 3 can be retracted into the swing bracket 2. Preferably, the swing bracket 2 has a frame structure, which facilitates using the interior of the frame as a receiving cavity 21 to house the working platform 3. It also has high structural strength and low weight. During equipment transport, the working platform 3 can be housed in the receiving cavity 26 inside the swing bracket 2 (specifically as shown in the figure). Figure 13As shown), it does not occupy additional space and has a compact structure. The work platform 3 can be unfolded by rotating (specifically as shown). Figure 14 As shown in the figure, the structure is simple and reliable, and when unfolded, it can simultaneously cover the working areas on both sides of the working face. Preferably, the working platform 3 can be driven to rotate by a cylinder, hydraulic cylinder, or motor.

[0057] Furthermore, in this embodiment, both the first working platform 31 and the second working platform 32 include a base plate 33 hinged to the lifting seat 23 and a guardrail mounted on the base plate 33. The guardrail includes a stop bar 34 arranged parallel to the base plate 33 and multiple parallel connecting rods 35. One end of each connecting rod 35 is hinged to the base plate 33, and the other end is hinged to the stop bar 34. After the base plate 33 is unfolded, the stop bar 34 is pulled upward, and each connecting rod 35 rotates upward (this can be done manually or automatically via a drive mechanism; details will not be elaborated further), thereby unfolding the guardrail and providing good protection for workers standing on the base plate 33 (specifically, as shown in the image). Figure 15 As shown in the diagram, the folding mechanism doesn't take up excessive space, making the structure both reasonable and effective. Finally, the sliding platform 37 slides to the left and right sides relative to the main platform 36, with the sliding distance adjusted according to the actual width of the working face, as detailed below. Figure 16 As shown.

[0058] 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.
