Description

Technical Field

[0001] This utility model relates to the technical field of tunnel face construction equipment, and in particular to a compact tunnel work 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.

After the swaying bracket swings to a vertical position, the folded work platform extends, thus meeting the needs of tunnel face construction such as blast hole loading. There is no need for manual erection and dismantling of scaffolding platforms, making it convenient and efficient to use.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1 Figures 1 to 7 This illustration shows an embodiment of the compact tunnel working vehicle of the present invention. The compact tunnel working vehicle of this embodiment includes a vehicle body 1, a loading platform 11 mounted on the vehicle body 1, a swing bracket 2 that can swing up and down on the loading platform 11, and a foldable working platform 3 mounted on the swing bracket 2. The working platform 3 can be folded 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, and also provides high structural strength and low weight.

[0040] The compact tunnel working vehicle of this embodiment is specifically as follows: Figure 1 As shown, when retracted, the swing bracket 2 is located on the loading platform 11, while the working platform 3 is folded and retracted into the receiving cavity 21 of the swing bracket 2. The structure is compact, occupies little space, allows for flexible relocation within tunnels, is highly mobile, and meets road traffic standards, enabling relocation between different tunnels. The loading platform 11 integrates the swing bracket 2 and the foldable working platform 3. After the swing bracket 2 swings to the vertical position (specifically as shown...), Figure 2 As shown), the folded work platform 3 extends and opens (specifically as shown). Figures 4 to 6 As shown in the figure, this meets the needs of tunnel face construction such as blast hole loading, eliminating the need for manual erection and dismantling of scaffolding platforms, making it convenient and efficient to use.

[0041] See the figure for details. Figures 4 to 5 As shown, in this embodiment, the working platform 3 is located on the left and right sides of the swing bracket 2 and is hinged to the swing bracket 2 (specifically, hinged to the lifting seat 22 on the swing bracket 2). The working platform 3 can be folded and unfolded by rotation, which has a simple structure and good reliability. After unfolding, it can simultaneously cover the working areas on the left and right sides of the working face. Preferably, the working platform 3 can be driven to rotate by a cylinder, hydraulic cylinder, or electric push rod.

[0042] Furthermore, in this embodiment, the work platform 3 includes a base plate 31 hinged to the swing bracket 2 and a guardrail 36 mounted on the base plate 31. The guardrail 36 includes a stop bar 32 arranged parallel to the base plate 31 and multiple parallel connecting rods 33. One end of each connecting rod 33 is hinged to the base plate 31, and the other end is hinged to the stop bar 32. After the base plate 31 is unfolded, the stop bar 32 is pulled upward, and each connecting rod 33 rotates upward (this can be done manually or automatically via a drive mechanism, details of which will not be elaborated further), thereby unfolding the guardrail 36. This provides good protection for workers standing on the base plate 31, while not taking up excessive space when folded, making the structure reasonable and effective.

[0043] See details Figure 6 and Figure 7 In this embodiment, the working platform 3 includes a main platform 34 hinged to the swing bracket 2 and a sliding platform 35 that can slide left and right relative to the main platform 34 (for example, the sliding platform 35 is driven to slide left and right relative to the main platform 34 by telescopic drive components such as cylinders, hydraulic cylinders, and electric push rods). The working platform 3 can be adjusted to slide according to the width of the working face, thereby achieving the effect of full coverage in the width direction of the working face.

[0044] See details Figure 1 and Figure 2 Preferably, in this embodiment, 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 loading platform 11 is provided with a swing drive component 12 for driving the swing bracket 2 to swing up and down.

[0045] Furthermore, the swing drive component 12 is a telescopic structure (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). One end of the swing drive component 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 component 12, the swing bracket 2 can be driven to swing up and down, realizing the switching between horizontal and vertical states of the swing bracket 2. The structure is simple and reliable. Preferably, swing drive components 12 are provided on both the left and right sides of the loading platform 11, which has good symmetry and balance and can provide sufficient driving force for the swing bracket 2.

[0046] See details Figure 6 and Figure 7 In this embodiment, the swing bracket 2 is equipped with a lifting seat 22 (for example, a lifting guide rail is provided on the swing bracket 2, the lifting seat 22 is located on the lifting guide rail, and the lifting seat 22 is driven to rise and fall by a cylinder, hydraulic cylinder, gear and rack mechanism, etc.), and the working platform 3 is located on the lifting seat 22. The lifting seat 22 can drive the working platform 3 to rise and fall, and the height of the working platform 3 can be adjusted, thereby achieving the effect of full coverage in the height direction of the working face. The structure is simple and effective.

[0047] In a preferred embodiment, there are two or more work platforms 3. Workers can use multiple work platforms 3 to perform tasks simultaneously, which helps to further improve efficiency.

[0048] In a preferred embodiment, the vehicle body 1 is provided with telescopic beams 13 on both the left and right sides, which can extend and retract in the left-right direction (or in the width direction of the vehicle body 1). The telescopic beams 13 are provided with telescopic outriggers 14 that can extend and retract in the vertical direction. Before the compact tunnel working vehicle enters the working state, the telescopic beams 13 drive the telescopic outriggers 14 to extend to the left and right sides. The telescopic outriggers 14 extend downward to contact the bottom surface of the tunnel, adjusting the vehicle body 1 to a horizontal state. At the same time, it can provide stable support for the vehicle body 1 to prevent overturning. The structure is simple, safe and reliable.

[0049] The method of using the compact tunnel boring machine in this embodiment is as follows: 1) Specifically, as follows Figure 1 As shown, the compact tunnel working vehicle is in the retracted state and travels 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 tunnel bottom, providing stable support for the vehicle body 1. 2) Specifically, as follows Figure 2 and Figure 3 As shown, the swing drive 12 drives the swing bracket 2 to swing upward to a vertical position; 3) Specifically, as follows Figure 4 As shown, the bottom plate 31 located inside the receiving cavity 21 rotates and unfolds to the left and right sides; 4) Specifically, as follows Figure 5 As shown, pulling up the stop bar 32 causes each link 33 to rotate upward, thus unfolding the guardrail 36; 5) Specifically, as follows Figure 6 As shown, the sliding platform 35 extends to the left and right sides according to the actual width of the working face; 6) Specifically, as follows Figure 7 As shown, the lifting platform 22 drives each working platform 3 to rise gradually, completing the loading operation of the entire working face.

[0050] Example 2 Figures 8 to 10 This paper illustrates another embodiment of the compact tunnel working vehicle of the present invention. The compact tunnel working vehicle of this embodiment is basically the same as that of Embodiment 1, except that: In this embodiment, the work platform 3 includes a base plate 31 hinged to the swing bracket 2 and an extension plate 37 hinged to the base plate 31. The rotation axis of the extension plate 37 is arranged perpendicular to the rotation axis of the base plate 31. Figure 8In this design, the rotation axis of the base plate 31 is arranged along the front-to-back direction, while the rotation axis of the extension plate 37 is arranged along the vertical direction (or up-and-down direction). After the base plate 31 rotates and unfolds to the left and right, the extension plate 37 rotates and unfolds, which helps to expand the width of the work platform 3, making it more convenient for operators to use. Moreover, the structure is simple and occupies little space when folded up.

[0051] Furthermore, in this embodiment, the guardrail 36 adopts an integrated structure (equivalent to the fixed connection between the stop bar 32 and the connecting rod 33 in Embodiment 1). The base plate 31 and the extension plate 37 are respectively hinged to a guardrail 36, and the rotation axis of the guardrail 36 is parallel to the rotation axis of the extension plate 37. After the extension plate 37 is rotated out, the guardrail 36 can be further rotated open, which can also provide good protection for workers standing on the base plate 31 and the extension plate 37, while not taking up too much space when folded. The structure is reasonable and effective.

[0052] 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.
