Description

Technical Field

[0001] This invention belongs to the field of duct installation technology, and relates to a duct installation vehicle for tunnels and its usage method. Background Technology

[0002] During tunnel construction, ventilation is crucial for ensuring air quality, removing dust and harmful gases, ensuring worker safety, and facilitating smooth construction. For tunnel structures with twin main tunnels or auxiliary passages, ventilation ducts need to be laid over long distances along the tunnel arch or waist, with the positions of fans and ducts constantly adjusted as excavation progresses. Currently, duct installation and dismantling generally rely on manual labor combined with general-purpose machinery such as loaders and aerial work platforms. In practice, workers use the loader bucket to raise the working height, hoisting the duct sections one by one to the designated suspension points, and then securing them to the initial support structure using wire ropes or lifting rings. This method is widely used in various mountain tunnels and urban subway sections, featuring readily available equipment and strong adaptability, and constitutes the main implementation path for current tunnel ventilation duct installation and dismantling operations.

[0003] However, the ductwork is heavy and installed at great heights, making manual handling and positioning labor-intensive, especially at high altitudes, over long distances, or in high-temperature and high-humidity environments. This can easily lead to worker fatigue and affect construction efficiency. Furthermore, the loader bucket is not a stable platform specifically designed for high-altitude operations, posing a risk of falls for personnel standing on it. Its safety protection capabilities are insufficient and fail to meet modern safety management requirements. In addition, the ductwork has hanging holes at regular intervals, requiring manual rope threading for securing each duct. This cumbersome and time-consuming process results in excessively long ductwork disassembly and assembly cycles, which in turn prolongs fan downtime and affects continuous ventilation within the tunnel, particularly during the tunnel ventilation phase where ductwork is frequently moved. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a duct installation vehicle for tunnels and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a duct installation vehicle for tunnels, comprising a steering unit, a vehicle, and a robotic arm unit. The steering unit is fixedly installed on the upper end of the vehicle, which is used to move back and forth within the tunnel. A steel wire rope and support are installed within the tunnel. The steel wire rope is fixedly connected to the support via connectors. The steering unit is movably connected to the robotic arm unit. A duct is fitted onto the end of the steel wire rope, and the duct has hanging holes for installation or removal via the robotic arm unit.

[0006] Furthermore, the robotic arm unit includes a main robotic arm unit and a second robotic arm unit disposed on one side of the first robotic arm unit. One end of the first robotic arm unit and the second robotic arm unit are fixedly connected to the steering unit, and the outer wall of the other end is fitted with an air duct. The end of the second robotic arm unit is provided with a fixedly connected hanging basket.

[0007] Furthermore, the first robotic arm unit includes a first robotic arm A, a first robotic arm B, and a first robotic arm C.

One end of the support arm is fixedly connected to the first robotic arm B, and the other end is fixedly connected to the first robotic arm C. One end of the hydraulic rod is hinged to the support arm, and the other end is fixedly connected to the first robotic arm B.

[0008] Furthermore, the second robotic arm unit includes a second robotic arm A and a second robotic arm B. One end of the second robotic arm A is fixedly connected to the steering unit, and the other end is movably connected to the second robotic arm B. The hanging basket is disposed at the end of the second robotic arm B.

[0009] Furthermore, the air duct is provided with a number of hanging holes, and the spacing between two adjacent hanging holes is the same.

[0010] Furthermore, the upper end of the first robotic arm C is provided with a fixing block and a connecting rope, and the fixing block is fixedly connected to the air duct through the connecting rope.

[0011] Furthermore, the robotic arm unit rotates 360° within the tunnel via a steering unit.

[0012] Furthermore, the tunnel includes a left main tunnel and a right main tunnel arranged in parallel, and vehicle-shaped passages A and B connected to the left main tunnel and the right main tunnel. The left main tunnel and the right main tunnel are equipped with fixedly connected wire ropes and supports.

[0013] The present invention also provides a method for using a duct installation vehicle for tunnels. Based on the above-mentioned duct installation vehicle for tunnels, the duct installation method of the method includes the following steps: fixing a steel wire rope to the support in the tunnel through a connector; driving the duct installation vehicle to a preset installation position by a vehicle; adjusting the robotic arm unit through a steering unit to align the robotic arm unit with the end of the steel wire rope; fitting the duct onto the end of the steel wire rope, and connecting the robotic arm unit to the hanging hole on the duct to fix the duct to the steel wire rope.

[0014] Furthermore, the method for disassembling the ductwork includes the following steps: driving the ductwork installation vehicle to a preset disassembly position; adjusting the robotic arm unit through the steering unit, aligning the robotic arm unit with the hanging hole of the ductwork to be disassembled; and disassembling the ductwork from the wire rope through the robotic arm unit.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention discloses a duct installation vehicle for tunnels. A steering unit is fixedly mounted on the upper part of the vehicle and movably connected to a robotic arm unit, allowing the duct installation vehicle to move back and forth within the tunnel, adapting to the complex and ever-changing working environment inside the tunnel. Steel wire ropes within the tunnel are fixedly connected to the support structure via connectors.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] Example 1 The present invention discloses a duct installation vehicle for tunnels, comprising a steering unit 1, a vehicle 2, and a robotic arm unit 3. The steering unit 1 is fixedly installed on the upper end of the vehicle 2. The vehicle 2 is used to move back and forth in the tunnel. A steel wire rope 4 and a support 5 are provided in the tunnel. The steel wire rope 4 is fixedly connected to the support 5 through a connector. The steering unit 1 is movably connected to the robotic arm unit 3. A duct 6 is sleeved on the end of the steel wire rope 4. The duct 6 is provided with a hanging hole 62. The mechanical arm unit 3 is used to install or remove the steel wire rope 4.

[0022] Specifically, the duct installation vehicle used in the tunnel includes a steering unit 1, a vehicle 2, and a robotic arm unit 3. The steering unit 1 is fixedly mounted on the upper end of the vehicle 2, which is responsible for moving back and forth within the tunnel to adapt to the construction needs of different sections. Steel wire ropes 4 and supports 5 are pre-installed inside the tunnel, and the steel wire ropes 4 and supports 5 are fixedly connected by connectors to form a stable support structure. The steering unit 1 is movably connected to the robotic arm unit 3, allowing the robotic arm unit 3 to flexibly adjust its position. A duct 6 is fitted onto the end of the steel wire rope 4, and the duct 6 has hanging holes 62. The robotic arm unit 3 enables the installation or removal of the duct 6 from the steel wire rope 4.

[0023] The robotic arm unit 3 includes a main robotic arm unit and a second robotic arm unit located on one side of the first robotic arm unit. One end of both the first and second robotic arm units is fixedly connected to the steering unit 1, and the outer wall of the other end is fitted with an air duct 6, which supports the air duct 6 throughout the movement. The end of the second robotic arm unit is provided with a fixedly connected hanging basket 7 for accommodating the operator.

[0024] The first robotic arm unit includes a first robotic arm A31, a first robotic arm B32, and a first robotic arm C33. One end of the first robotic arm A31 is fixedly connected to the steering unit 1, and the other end is movably connected to the first robotic arm B32. The other end of the first robotic arm B32 is movably connected to the first robotic arm C33. A duct 6 is fitted onto the outer surface of the first robotic arm C33 to ensure stability during transportation and installation. A support arm 34 and a hydraulic rod 35 are provided between the first robotic arms B32 and C33. One end of the support arm 34 is fixedly connected to the first robotic arm B32, and the other end is fixedly connected to the first robotic arm C33. One end of the hydraulic rod 35 is hinged to the support arm 34, and the other end is fixedly connected to the first robotic arm B32. The angle and height of the robotic arm are adjusted by extending and retracting the hydraulic rod 35 to adapt to different installation heights within the tunnel.

[0025] The second robotic arm unit includes a second robotic arm A36 and a second robotic arm B37. One end of the second robotic arm A36 is fixedly connected to the steering unit 1, and the other end is movably connected to the second robotic arm B37. The basket 7 is set at the end of the second robotic arm B37, and the air duct 6 is sleeved on the outer surface of the first robotic arm unit to realize the synchronous conveying of the air duct 6.

[0026] like Figure 3 As shown, the duct 6 is provided with several hanging holes 61, with the same spacing between two adjacent hanging holes 61. In this embodiment, the spacing between two adjacent hanging holes 61 is 1.5m to ensure that the duct 6 is evenly distributed on the wire rope 4 and to avoid local stress concentration. The upper end of the first robotic arm C33 is provided with a fixing block 8 and a connecting rope 9. The fixing block 8 is fixedly connected to the duct 6 through the connecting rope 9 to prevent the duct 6 from slipping or shifting during installation. The robotic arm unit 3 can rotate 360° in the tunnel through the steering unit 1, which can adapt to the installation requirements of the duct 6 at different cross-sectional positions in the tunnel. Whether it is the top of the tunnel, the side wall, or other special positions, the working angle of the robotic arm unit 3 can be adjusted through the steering unit 1, without the need to frequently move the vehicle 2, thereby improving the flexibility and efficiency of the operation and increasing the installation accuracy and efficiency.

[0027] The tunnel includes a parallel main tunnel left line 10 and a main tunnel right line 11, as well as vehicle-shaped passageways A12 and B13 that connect to the main tunnel left line 10 and the main tunnel right line 11. The main tunnel left line 10 and the main tunnel right line 11 serve as construction passageways and operation passageways, respectively, and both require the installation of ventilation ducts 6 to ensure ventilation needs. The ventilation duct installation vehicle can move flexibly between the main tunnel left line 10 and the main tunnel right line 11 through vehicle-shaped passageway A12 or vehicle-shaped passageway B13 to realize the installation of ventilation ducts 6 on both lines without the need to configure equipment on each line separately, which effectively reduces construction costs.

[0028] Inside the left line 10 and right line 11 of the main tunnel, according to the installation design requirements of the duct 6, the steel wire rope 4 is fixed to the support 5 using connectors. The duct 6 to be installed is moved to the vicinity of vehicle 2. The operator starts the robotic arm unit 3 through the equipment control system. Driven by the steering unit 1, the first and second robotic arm units are rotated to the placement position of the duct 6. The angles and positions of the first robotic arm A31, first robotic arm B32, first robotic arm C33, and second robotic arm A36 and second robotic arm B37 are adjusted by extending and retracting the hydraulic rod 35, so that the ends of the first robotic arm C33 and the second robotic arm B37 are aligned with one end opening of the duct 6. Vehicle 2 is slowly pushed or the robotic arm unit 3 is adjusted to fit the outer wall of the first robotic arm C33 into the duct 6 until the length direction of the duct 6 is consistent with the extension direction of the robotic arm unit 3. Then, the connecting rope 9 on the first robotic arm C33 is fixedly connected to the duct 6 to ensure that the duct 6 is securely fitted.

[0029] like Figure 1 As shown, after the duct 6 is installed, the vehicle 2 moves within the tunnel to the designated installation area on the left line 10 or right line 11 of the main tunnel, according to the installation location requirements. The steering unit 1 and robotic arm unit 3 are activated via the equipment control system, adjusting the angle and height of the robotic arm unit 3. First, the steering unit 1 drives the robotic arm unit 3 to rotate, aligning the duct 6 with the direction of the wire rope 4. Then, the extension and retraction of the hydraulic rod 35 adjusts the angles of the first robotic arm B32 and the first robotic arm C33, as well as the angles of the second robotic arm A36 and the second robotic arm B37, raising the duct 6 to a height level with the wire rope 4, and aligning the hanging holes 61 on the duct 6 with the preset fixing points of the wire rope 4. The operator stands on the hanging basket 7 and connects and fixes the hanging holes 61 of the duct 6 to the wire rope 4, ensuring that each hanging hole 61 is securely connected and the duct 6 is suspended stably. After fixing, untie the connecting rope 9 on the first robotic arm C33, and through the reverse action of the robotic arm unit 3, pull the first robotic arm C33 and the second robotic arm B37 out of the air duct 6 to complete the installation of a single air duct 6.

[0030] After the installation of duct 6 at one location is completed, vehicle 2 moves to the next installation location and repeats the installation process. If switching between the left line 10 and the right line 11 of the main tunnel, vehicle 2 can be driven through vehicle-type passage A12 or B13 to enter the other main tunnel without needing to readjust the equipment; work can begin immediately. Figure 4 As shown and as Figure 5 As shown.

[0031] like Figure 2As shown, when duct 6 needs to be disassembled, the process is the reverse of the installation process. First, vehicle 2 is moved to the disassembly position of duct 6. Through the coordinated action of steering unit 1 and robotic arm unit 3, the first robotic arm C33 and the second robotic arm B37 are inserted into duct 6 and secured with connecting rope 9. The operator stands on the hanging basket 7, disconnects the connection between the hanging hole 61 in duct 6 and the wire rope 4, and then slowly lowers duct 6 through robotic arm unit 3. The position of vehicle 2 is adjusted to transfer duct 6 to the designated disassembly area, completing the disassembly operation.

[0032] In summary, the duct installation vehicle used in tunnels, through the steering unit 1, vehicle 2, and robotic arm unit 3, installs and dismantles the duct 6, improving work efficiency and reducing the labor intensity of operators compared to traditional manual methods. The 360° rotating steering unit 1 and the multi-section articulated robotic arm unit 3 adapt to the needs of different tunnel structures and installation locations. The fixing of the robotic arm unit 3 to the connecting rope 9 ensures the stability of the duct 6 during transportation, improving installation accuracy.

[0033] Example 2 The present invention discloses a method for using a duct installation vehicle for tunnels, including a duct installation method and a duct disassembly method.

[0034] The duct installation method includes the following steps: fixing the steel wire rope 4 to the support 5 inside the tunnel via a connector; driving the duct installation vehicle to the preset installation position using vehicle 2; adjusting the robotic arm unit 3 via steering unit 1, aligning the robotic arm unit 3 with the end of the steel wire rope 4; fitting the duct 6 onto the end of the steel wire rope 4, connecting the robotic arm unit 3 to the hanging hole 62 on the duct 6, and fixing the duct 6 to the steel wire rope 4. The duct disassembly method includes the following steps: driving the duct installation vehicle to the preset disassembly position; adjusting the robotic arm unit 3 via steering unit 1, aligning the robotic arm unit 3 with the hanging hole 62 of the duct 6 to be disassembled; and disassembling the duct 6 from the steel wire rope 4 using the robotic arm unit 3.

[0035] Specifically: First, the steel wire rope 4 is fixedly connected to the support 5 inside the tunnel via connectors, so that the steel wire rope 4 is laid at the arch or waist position along the tunnel extension direction, serving as the load-bearing path for the suspension of the air duct 6. After the steel wire rope 4 is installed, the air duct installation vehicle is started, which can freely enter and exit the left and right lines of the main tunnel, and travels to the preset installation position inside the tunnel. Area switching is achieved through vehicle lane A and vehicle lane B. After reaching the installation position, the operator starts the steering unit 1 through the control system, adjusts the position of the robotic arm unit 3, and aligns it with the end of the steel wire rope 4. The steering unit 1 can rotate 360° in the horizontal plane, so the robotic arm unit 3 can adapt to tunnel sections with different orientations, ensuring docking accuracy. The air duct 6 to be installed is placed on the steel wire rope 4, and the air duct 6 is provided with hanging holes 61. The robotic arm unit 3 is connected to the first hanging hole 61 on the air duct to form a traction point. As the air duct installation vehicle moves, the hanging holes 61 are connected to the steel wire rope 4 in sequence.

[0036] First, the duct installation vehicle is driven to the preset dismantling position, typically at the starting end of the duct 6 to be dismantled. The operator starts the equipment via the control panel and adjusts the robotic arm unit 3 using the steering unit 1, aligning it with the first hanging hole 61 on the duct 6. Once the robotic arm unit 3 is aligned with the hanging hole 61, the duct installation vehicle slowly moves forward along the duct's extension direction, detaching the duct 6 segment by segment from the steel cable 4. The dismantled duct 6 is then gathered by the first robotic arm C33 to prevent it from scattering or falling. Throughout the dismantling process, manual dragging is unnecessary, reducing labor intensity and safety risks. Once the entire duct 6 is completely detached from the steel cable 4, the duct installation vehicle carries the dismantled duct 6 out of the tunnel and transports it to the designated location.

[0037] In summary, the installation and dismantling of duct 6 is fully mechanized through a duct installation vehicle. This vehicle can operate flexibly in confined tunnel spaces, achieving precise docking in any direction via the 360° rotation of the steering unit 1, adapting to complex working conditions. Compared to the traditional method relying on loaders and manual labor, this reduces the time construction workers spend working at heights, avoids equipment interference, shortens the ventilation system adjustment cycle, and ensures the continuity and safety of tunnel construction.
