Description

Technical Field

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

[0013] As a further improvement to the above technical solution: the spacing adjustment mechanism includes a first linkage assembly, which includes two parallel and equal-length first linkages and a first linkage drive member for driving the first linkages to swing up and down. One end of the first linkage is hinged to the swing bracket, and the other end is hinged to the first lifting bracket.

[0014] As a further improvement to the above technical solution: the first link includes two first link segments and a first connector for connecting the two first link segments, with the two first link segments located on both sides of the first lifting bracket.

[0015] As a further improvement to the above technical solution: the first linkage drive member is a telescopic structure, one end of the first linkage drive member is hinged to the swing bracket, and the other end is hinged to the first connecting member of one of the first linkages.

[0016] As a further improvement to the above technical solution: the first lifting seat is provided with a rotating platform and a rotating drive component for driving the rotating platform to rotate, and the working platform is located on the rotating platform.

[0017] As a further improvement to the above technical solution: the rotating platform is hinged to the first 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 first lifting seat.

[0018] As a further improvement to the above technical solution: the rotating platform is provided with a rotating arm, the first 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.

The loading platform integrates a swing bracket, a first lifting bracket, a spacing adjustment mechanism, and a working platform. The spacing adjustment mechanism increases the distance between the first lifting bracket and the swing bracket. After the swing bracket swings from a horizontal state to a vertical state, the first lifting bracket can be flipped above the step on the working face.

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

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

[0038] Figures 1 to 10 This illustration shows an embodiment of the tunnel working vehicle device of the present invention. The tunnel working vehicle device of this embodiment includes a vehicle body 1, a swing bracket 2, a working platform 3, and a first lifting bracket 4. 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 distance adjustment mechanism for adjusting the distance is provided between the swing bracket 2 and the first lifting bracket 4. Preferably, the distance adjustment mechanism includes a first connecting rod assembly 5 (of course, in other embodiments, the distance between the first lifting bracket 4 and the swing bracket 2 can also be increased by means of jacking, etc.). A first lifting guide rail 41 is provided on the first lifting guide rail 41, and a first lifting seat 43 is provided on the first lifting guide rail 41. The working platform 3 is disposed on the first lifting seat 43. See details. Figures 3 to 5Preferably, a driver's cab 15 is located at the front end of the vehicle body 1, and a loading platform 11 is located 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. Swing drive components 12 are provided on both the left and right sides of the loading platform 11, providing good symmetry and balance. 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. Further details can be found in the following sections. Figure 7 and Figure 8 The vehicle body 1 is equipped with telescopic beams 13 that can extend and retract along the width direction on both the left and right sides. The telescopic beams 13 are equipped with telescopic outriggers 14 that can extend and retract along the vertical direction. Before the tunnel working vehicle device 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 of the tunnel, which can provide stable support for the vehicle body 1 and prevent overturning.

[0039] The tunnel working vehicle device of this embodiment has a compact structure when retracted, 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 linkage assembly 5, a first lifting bracket 4, and a working platform 3. The first linkage assembly 5 extends, increasing the distance between the first lifting bracket 4 and the swing bracket 2 (specifically as shown). Figure 3 As shown), after the swing bracket 2 swings from a horizontal state to a vertical state (specifically as shown in the figure), Figure 4 As shown), the first lifting bracket 4 can be flipped to above the step on the working face, and the first lifting seat 43 can move along the first lifting guide rail 41 (for example, driven by a lifting drive assembly 42 such as a hydraulic cylinder, screw and nut mechanism, gear and rack mechanism or commercially available lifting machine), thereby driving the working platform 3 to rise and fall. The height of the working platform 3 can be adjusted to meet the needs of loading explosives into the blast hole (specifically as shown). Figure 7 and Figure 8 As shown in the figure, no manual erection or dismantling of scaffolding platforms is required, making it convenient and efficient to use.

[0040] Furthermore, in this embodiment, the first linkage assembly 5 includes two parallel and equal-length first linkages 51 and a first linkage drive member 52 for driving the first linkages 51 to swing up and down. One end of the first linkage 51 is hinged to the swing bracket 2, and the other end is hinged to the first lifting bracket 4. See details. Figure 3 and Figure 4The swing bracket 2, the two first connecting rods 51, and the first lifting bracket 4 can form a parallelogram. Driven by the first connecting rod drive member 52, the two first connecting rods 51 swing upward synchronously, causing the first lifting bracket 4 and its working platform 3 to rise and move forward as a whole, with good stability. This allows the first lifting bracket 4 to flip over to above the step on the working face when the swing bracket 2 swings upward to a vertical position. After the first lifting bracket 4 flips over to above the step on the working face, the first connecting rod drive member 52 restricts the first connecting rods 51 from swinging downward, thus providing stable support for the first lifting bracket 4. The structure is reasonable and effective.

[0041] Furthermore, in this embodiment, the first connecting rod 51 includes two first connecting rod segments 511 and a first connecting member 512 (e.g., connecting rod, connecting plate, etc.) for connecting the two first connecting rod segments 511. The two first connecting rod segments 511 are disposed on both sides of the first lifting bracket 4. The first lifting bracket 4 has a certain width. By configuring the first connecting rod 51 into a structure containing two first connecting rod segments 511 and disposing it on both sides of the first lifting bracket 4, and connecting the first connecting rod segments 511 into a whole through the first connecting member 512, good symmetry is achieved, which is beneficial for driving the overall movement of the first lifting bracket 4.

[0042] Furthermore, the first linkage drive member 52 is a telescopic structure (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). One end of the first linkage drive member 52 is hinged to the swing bracket 2, and the other end is hinged to the first connecting member 512 of one of the first linkages 51. The extension and retraction of the first linkage drive member 52 drives the movement of the first connecting member 512 connected to it, thereby realizing the swing of the first linkage 51. The structure is simple and has good reliability. Preferably, two first linkage drive members 52 are provided and distributed at both ends of the first connecting member 512, which has good symmetry and is beneficial for driving the overall movement of the first linkage 51.

[0043] Furthermore, in this embodiment, the first lifting seat 43 is provided with a rotating platform 44 and a rotating drive component 45 for driving the rotating platform 44 to rotate. The working platform 3 is disposed on the rotating platform 44 (specifically, the platform body 33 of the working platform 3 is disposed on the rotating platform 44). The working platform 3 is integrated and installed on the rotating platform 44 with rotating 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 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.

[0044] See details Figure 9In this embodiment, the rotating platform 44 is hinged to the first lifting seat 43, and the rotating drive component 45 is a telescopic structure (e.g., a cylinder, hydraulic cylinder, electric push rod, etc.). One end of the rotating drive component 45 is hinged to the rotating platform 44, and the other end is hinged to the first lifting seat 43. By extending and retracting the rotating drive component 45, the rotating platform 44 can be driven to rotate relative to the first lifting seat 43. The structure is simple and has good reliability.

[0045] Furthermore, in this embodiment, the rotating platform 44 is provided with a rotating arm 441, and the first lifting seat 43 is provided with a first limiting part 431 and a second limiting part 432. The rotating arm 441 is located between the first limiting part 431 and the second limiting part 432. When the rotating arm 441 rotates with the rotating platform 44 and contacts the first limiting part 431 or the second limiting part 432, it indicates that the rotating platform 44 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 44.

[0046] Specifically, such as Figure 6 As shown, in this embodiment, the tunnel working vehicle device also includes a second lifting bracket 6. A second linkage assembly 7 is provided between the second lifting bracket 6 and the rotating platform 44. The second linkage assembly 7 includes two parallel and equal-length second linkages 71 and a second linkage drive member 72 for driving the second linkages 71 to swing up and down. One end of the second linkage 71 is hinged to the rotating platform 44, and the other end is connected to the second lifting bracket 6. The working platform 3 is mounted on the second lifting bracket 6. The operating principle of the second linkage assembly 7 is the same as that of the first linkage assembly 5, and will not be described in detail. The difference is that the length of the second linkage 71 is shorter than that of the first linkage 51, and since the load of the second linkage 71 is less than that of the first linkage 51, the load-bearing capacity requirement of the second linkage 71 is lower than that of the first linkage 51. By swinging the second linkage 71, the distance between the working platform 3 and the working face can be finely adjusted, making the operation more convenient. At the same time, the height of the working platform 3 will also change.

[0047] See details Figure 10 In this embodiment, the second lifting bracket 6 is provided with a second lifting guide rail 61, and the working platform 3 includes a first working platform 31 and a second working platform 32. The first working platform 31 and / or the second working platform 32 can move along the second lifting guide rail 61 (e.g., driven by a cylinder, hydraulic cylinder, electric push rod, etc.). Simultaneously providing the first working platform 31 and the second working platform 32 allows for the use of more workers and equipment, thereby further improving work efficiency. The first working platform 31 and / or the second working platform 32 are spaced apart by moving along the second lifting guide rail, avoiding mutual interference. During relocation, the first working platform 31 and the second working platform 32 move closer together, saving space.

[0048] See details Figure 7 , Figure 8 and 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 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 of the working face.

[0049] The method of using the tunnel working vehicle device of the present invention is as follows: 1) Specifically, as follows Figure 1 As shown, the tunnel working vehicle device is in the retracted state and reverses to the vicinity of the tunnel face. 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, which can provide stable support for the vehicle body 1. 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 first linkage assembly 5 swings upward, causing the first lifting bracket 4 and the rest of the assembly to rise and move forward. 4) Specifically, as follows Figure 4 As shown, the swing bracket 2 swings upward to a vertical position, at which point the first lifting bracket 4 flips over to the top of the step on the working face; 5) Specifically, as follows Figures 5 to 7 As shown, the first lifting seat 43 descends to a low position along the first lifting guide rail 41, and then gradually rises to complete the loading operation of the entire working face; during the operation, the extension amount of the telescopic platform 34 is adjusted according to the actual width of the working face.

[0050] 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.
