Description

Technical Field

[0001] This application relates to the technical field of tunnel construction, and in particular to a lining method for an emergency passing lane in a tunnel and a tunnel lining trolley. Background Technology

[0002] With the continuous development of road infrastructure in my country, tunnels are typically built when encountering mountains, allowing vehicles to pass through and shortening travel time, thus providing convenience for people's work and travel. In long tunnels, to ensure driving safety, emergency passing lanes are usually installed at intervals within the tunnel to provide a safe space for vehicles that break down, ensuring the safety of the vehicle and its occupants.

[0003] In related technologies, during the construction of emergency passing lanes, it is necessary to line the sidewalls of the emergency passing lanes to ensure their strength. Since the radius of the emergency passing lane is larger than the diameter of the main tunnel, the main tunnel is usually lined first. Then, the main gantry at the trolley in the main tunnel is removed, a secondary gantry is installed, and the trolley is moved to the emergency passing lane to line its sidewalls.

[0004] Regarding the aforementioned technologies, each time the sidewall of an emergency passing lane is lined, the gantry needs to be replaced, replacing the mechanism for compacting the sidewall with the mechanism for lining the sidewall. At the same time, the trolley needs to be moved, which reduces the efficiency of the lining operation of the emergency passing lane and increases the workload of the operators. Summary of the Invention

[0005] In order to avoid replacing the gantry and quickly complete the lining of the emergency passing lane, this application provides a lining method for the emergency passing lane in a tunnel and a tunnel lining trolley.

[0006] This application provides a lining method for emergency passing lanes in tunnels and a tunnel lining trolley, employing the following technical solution: A method for lining an emergency passing lane in a tunnel and a tunnel lining trolley, including a main trolley and an auxiliary trolley; The main trolley includes a first horizontal plate, and a fixed column is provided below the first horizontal plate. The first horizontal plate can slide along the fixed column. The auxiliary trolley includes a support plate, and a fixed column is provided below the support plate, allowing the support plate to slide along the fixed column; The first horizontal plate, the fixed column, the bearing plate, and the fixed column are all fixedly connected to a fixed plate. The fixed plate is equipped with an mounting plate. The mounting plate has a placement groove and a vertical groove, and the placement groove and the vertical groove are connected. The placement groove is equipped with a material storage component and a third cylinder. The third cylinder is fixedly connected to the mounting plate. The inner cavity of the vertical groove is equipped with a jack and an abutment plate. One end of the jack is fixedly connected to the mounting plate, and the other end is fixedly connected to the abutment plate. The abutment plate is equipped with extrusion plates on both sides in the driving direction of the third cylinder. The extrusion plates are slidably connected to the mounting plate.

[0007] By adopting the above technical solution, the fixed column provides support for the installation of the first horizontal plate, and the first horizontal plate can be raised and lowered along the fixed column. The fixed column provides support for the installation of the bearing plate, and the bearing plate can also be raised and lowered along the fixed column. The mounting plate is installed on the fixed plate, and the mounting plate can adjust its angle and distance relative to the fixed plate. The mounting plate provides support for the installation of the placement slot and the vertical slot. The placement slot provides support for the installation of the storage assembly, and the vertical slot provides support for the installation of the jack and the abutment plate. When it is necessary to line the tunnel wall, the jack abuts the plate, and the third cylinder drives the lining plate in the storage assembly to enter the abutment plate. The two extrusion plates limit the lining plate. Then, the jack drives the abutment plate away from the mounting plate, thereby fixing the lining plate fixed to the mounting plate in the corresponding position in the tunnel, completing the installation of the lining plate. By changing the position of the mounting plate relative to the fixed plate, the sidewall of the emergency passing lane can be lined accordingly.

[0008] Optionally, the material storage assembly includes multiple support plates, the support plates forming a material storage gap, a baffle plate fixedly connected to the bottom wall of the support plate, the baffle plate being equipped with a lifting cylinder, and the support plate being equipped with a positioning plate, the positioning plate being slidably connected to the support plate.

[0009] By adopting the above technical solution, the support plate can create a material storage gap, which can limit the movement of the lining plate. The baffle plate can seal the bottom wall of the support plate, thereby preventing the lining plate from falling. The lifting cylinder can drive the lining plate upward, and the third cylinder can drive the lining plate into the bearing plate.

[0011] By adopting the above technical solution, the installation groove can provide support for the installation of the sliding plate. When the operator stores the lining plate, the operator slides the limiting plate into the installation groove. At this time, the material storage gap is unobstructed, making it easy for the operator to put in the lining plate. Then, the operator uses the limiting plate to enter the material storage gap. When the lining plate slides upward, the lining plate and the limiting plate come into contact. At this time, the limiting plate rotates in one direction, which can effectively prevent the lining plate from falling back.

[0012] Optionally, the fixing plate is provided with an adjustment assembly, which includes a rotating tube and a mounting rod. The rotating tube is rotatably connected to the fixing plate, and the mounting rod passes through the inner cavity of the rotating tube and is threadedly connected to the rotating tube. Support rods are provided on both sides of the mounting rod along its axial direction. One end of the support rod is rotatably connected to the mounting rod, and the other end is rotatably connected to the fixing plate.

[0013] By adopting the above technical solution, the rotating tube and the mounting rod are threaded together. The rotating tube rotates while the mounting rod is limited by the support rod. The length of the support rod is variable, which allows the mounting rod to slide along the axis of the rotating tube. At the same time, the support rod can provide a certain support for the mounting rod, thereby ensuring the stability of the mounting plate.

[0014] Optionally, the adjustment assembly further includes a second motor, a gear, and a gear ring. The second motor drives the gear to rotate, and the gear ring is coaxially and fixedly connected to the rotating tube. The gear and the gear ring mesh.

[0015] By adopting the above technical solution, the second motor drives the gear to rotate, the gear meshes with the gear ring, thereby driving the gear ring to rotate. The gear ring is fixedly connected to the rotating tube, thereby causing the rotating tube to rotate and driving the mounting rod to move.

[0016] Optionally, the fixed column is equipped with a supporting column, the supporting column passes through the fixed column and is slidably connected to the fixed column, and the supporting column is fixedly connected to the first horizontal plate. The bearing plate is equipped with a fixed column, a support column, and a second horizontal plate. The support column passes through the fixed column and is slidably connected to the fixed column. The support column is fixedly connected to the second horizontal plate. A third drive cylinder is provided between the second horizontal plate and the bearing plate.

[0017] By adopting the above technical solution, the support column slides along the fixed column, thereby driving the first horizontal plate to slide; the fixed column provides installation support for the support column, the support column slides along the fixed column, thereby driving the second horizontal plate to slide, the second horizontal plate provides installation support for the bearing plate, and at the same time, the third drive cylinder drives the bearing plate to slide towards or away from the bearing plate, thereby changing the position of the fixed plate and lining the tunnel wall at different positions.

[0018] Optionally, the main trolley further includes a fixing component, which is fixedly connected to the fixed column; The auxiliary trolley also includes a support frame, which is fixedly connected to the support column.

[0019] By adopting the above technical solution, the fasteners can connect and support the fixed columns, and the support frame can provide support for the fixed columns, thereby ensuring the stability of the connection between the fixed columns and between the fixed columns.

[0020] Optionally, the fixing member is provided with a sliding groove, and the inner cavity of the sliding groove is provided with a slider. The slider is fixedly connected to the support frame and can slide along the sliding groove. The inner cavity of the fixing member is provided with a fourth driving cylinder. One end of the fourth driving cylinder is fixedly connected to the fixing member and the other end is fixedly connected to the support frame.

[0021] By adopting the above technical solution, the slide provides support for the installation of the slider and limits the sliding direction of the slider. The slider and the support frame are fixedly connected. The fourth drive cylinder can drive the support frame to slide along the slide, so that the auxiliary trolley can slide out from under the main trolley and then line the side wall of the emergency avoidance lane.

[0022] Optionally, both the fixed column and the bottom wall of the fixed column are provided with a traveling mechanism. The traveling mechanism includes a base plate, a track and two traveling wheels. The base plate and the fixed column and / or the fixed column are rotatably connected. Both traveling wheels are rotatably connected to the base plate. The track is sequentially wrapped around the two traveling wheels and meshes with the traveling wheels.

[0023] By adopting the above technical solution, the base plate and the fixed column and / or the fixed column are rotatably connected, thereby driving the traveling wheel to rotate in the vertical direction. The traveling wheel rotates along the base plate, and the traveling wheel and the track mesh, thereby causing the track to rotate, which in turn drives the main trolley and the auxiliary trolley to move.

[0024] Optionally, a tunnel lining trolley according to any one of claims 1-9 includes the following steps: S1: The tracks drive the main trolley and the auxiliary trolley to move along the tunnel. When it is necessary to line the emergency avoidance lane, the fourth drive cylinder drives the fixed frame to slide along the slide groove, thereby driving the auxiliary trolley to slide out from under the main trolley. S2: Adjust the angle of the rotating tube relative to the fixed plate. The second motor drives the rotating tube to rotate through the cooperation of the drive gear ring. The mounting rod is limited by the support rod, causing the mounting rod to slide out. At the same time, the angle of the mounting plate relative to the mounting rod is adjusted. S3: The jack drives the contact plate to retract into the vertical groove; S4: The lifting cylinder drives the lining plate to slide along the support plate, while the limiting plate provides a limiting effect on the lining plate. After the lining plate slides out of the support plate, the third drive cylinder drives the lining plate to slide above the abutment plate and positions the lining plate between the two extrusion plates. S5: The jack drives the abutment plate away from the mounting plate and fixes the lining plate in the corresponding position.

[0025] By adopting the above technical solution, during lining operations, the tracks drive the main trolley and auxiliary trolley to slide together along the tunnel. When lining the emergency passing lane is required, the fourth drive cylinder drives the auxiliary trolley to slide out from under the main trolley. The operator adjusts the angle of the rotating tube, and then the second motor, through the engagement of the gear and ring gear, drives the rotating tube to rotate, causing the mounting rod to move. The operator then adjusts the angle of the mounting plate. At this time, the lifting cylinder drives the lining plate upward, and the lining plate contacts the limiting plate, which sequentially limits the lining plate. The third drive cylinder drives the lining plate into the space between the two extrusion plates, and the two extrusion plates limit the lining plate. Then, the jack drives the abutment plate to move, bringing the lining plate to the corresponding position.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a support mechanism, operators can adjust the position between the rotating tube and the mounting rod, and use jacks and locking devices to perform lining work on the tunnel wall at different locations, avoiding the need to replace different frames and improving the work efficiency of operators; 2. By setting up a traveling mechanism, it is convenient for operators to control the movement of the main carriage and the auxiliary carriage, and at the same time, the auxiliary carriage is pushed out from under the main carriage; 3. By setting up a storage component, multiple lining plates can be stored at once, avoiding the need for operators to frequently change and install lining plates. Attached Figure Description

[0052] The implementation principle of a tunnel lining trolley according to an embodiment of this application is as follows: The first motor 32 drives the traveling wheels 34 to rotate, which in turn drives the track 33 to rotate, causing the main trolley 1 and the auxiliary trolley 2 to move. When preparing for lining, the operator first slides the sliding plate 451 and the limiting plate 452 into the inner cavity of the mounting groove, and then places the lining material into the storage gap 442. The auxiliary trolley 2 adjusts the height of the bearing plate 25 through the third drive cylinder 26.

[0053] When the emergency lane needs lining, the fourth drive cylinder 35 drives the auxiliary trolley 2 to slide out, while the slide groove 16 provides a limit for the sliding of the auxiliary trolley 2. Then, the operator adjusts the angle of the rotating tube 421, and the second motor 423 drives the rotating tube 421 to rotate through the cooperation between the gear 424 and the ring gear 425. The support rod 426 can provide a limit and support for the mounting rod 422, thereby driving the mounting plate 43 to move.

[0054] Subsequently, the lifting cylinder 4431 drives the lining plate upward, while the limiting plates 452 sequentially limit the lining plate to prevent it from sliding downward.
