Description

Technical Field

[0001] This application relates to the field of tunnel construction, and in particular to a shield tunneling translation and air-pushing device for tunneling stations. Background Technology

[0002] With the development of society, urban underground transportation has developed rapidly. In the process of tunnel construction, tunnel boring machines (TBMs) are usually used. The TBM construction technology has also reached a high level. After the first section is completed, it is necessary to pass through the subway station to enter the next section. The TBM itself cannot move forward on its own and requires external force to push it forward.

[0003] In related technologies, a shield tunneling machine (TBM) is disclosed as a device for empty-push-through-station operation, including a track assembly and a reaction support. A liner plate, slidable relative to the track assembly, is placed on the track assembly, and its upper surface provides a support surface for connecting the bottom of the TBM receiving base. The reaction support is detachably connected to the track assembly and is used to connect the force-bearing plate at the tail of the TBM receiving base. A space for jack placement is formed between the reaction support and the force-bearing plate. Before empty-push-through-station operation, two perforated travel rails are laid under the TBM receiving base. The reaction support serves as a jack support plate. The jacks are placed on the perforated travel rails and within the space between the pin-type reaction support and the force-bearing plate. The TBM host is then welded to the TBM receiving base. During the forward movement of the TBM host, the perforated travel rails at the rear of the pin-type reaction support are removed and re-laid, allowing for cyclical use and enabling the TBM to empty-push-through-station operation.

[0004] Regarding the aforementioned technologies, the reaction support is used as the jack support plate, and the jack pushes the tunnel boring machine. However, during the advance of the tunnel boring machine, the reaction support needs to be removed before the jack can push again, resulting in a relatively complicated empty push operation. Summary of the Invention

[0005] To improve the problem of complex air-propulsion operation, this application provides a shield tunneling translation air-propulsion station crossing device.

[0006] The shield tunneling machine translation and air-push passing device provided in this application adopts the following technical solution: A shield tunneling machine translation and air-pushing device includes a moving component, a supporting component, and a telescopic component. The moving component is installed on the ground and is used to move the shield tunneling machine. The supporting component includes at least one support member for supporting the shield tunneling machine to slide towards the next section. The support member includes two guide rails, which are horizontally arranged and oriented in the same direction as the shield tunneling machine's travel direction. The two guide rails are parallel to each other, allowing the shield tunneling machine to slide on the two guide rails. The guide rail has a placement groove at the end away from the tunnel entrance. The telescopic assembly is located in the placement groove. The telescopic assembly includes a fixed box, a stop block, and at least one telescopic member. The fixed box is vertically arranged, with one end extending into the placement groove and connected to the guide rail. The top of the fixed box is flush with the surface of the guide rail and is open. The stop block is located inside the fixed box, with its sidewall fitting against the inner wall of the fixed box. The stop block is slidably disposed in the fixed box and slides towards or away from the bottom wall of the fixed box. The stop block is used to abut against the second jack. One end of the telescopic member is fixed to the bottom wall of the stop block, and the other end is fixed to the bottom wall of the fixed box.

[0007] By adopting the above technical solution, when the tunnel boring machine (TBM) needs to be pushed without contact with the ground, after the TBM emerges from the previous tunnel section, it needs to be measured and positioned to determine its location. The TBM is positioned on a moving assembly, which then translates and adjusts its position so that its centerline is aligned with the centerline of the TBM's transit track. Next, guide rails are laid below the TBM, allowing it to slide on them. With the TBM positioned on the guide rails, the second jack is connected to the tail of the TBM according to pre-set requirements. Then, the end of the second jack furthest from the TBM is fixed to the guide rail. The second jack is then activated, driving the TBM to slide towards the next section on the guide rail. When the TBM reaches the stop, further pushing is performed, pressing the stop against it. At this point, the stop moves towards the side closest to the bottom wall of the fixed box, extending and retracting. The telescopic component shortens, the second jack pushes the guide rail a certain distance, retracts the second jack so that it can pass the stop block, and then the telescopic component extends, the stop block moves away from the fixed and bottom wall, the second jack is restarted, this time the second jack is pressed against the stop block, the second jack pushes the tunnel boring machine to the next section, no need to fix the second jack and guide rail again. According to the above operation, the second jack is started until the tunnel boring machine is pushed to the next section. Compared with related technologies, this application starts the second jack, the second jack pushes the tunnel boring machine, the second jack passes the stop block during the retraction process, and then the second jack only needs to be pressed against the stop block, no need to fix the second jack and guide rail again, the second jack can push the tunnel boring machine to move, which is beneficial to improving the problem of more complex empty push operation.

[0008] Optionally, the guide rail is provided with an arc-shaped plate at the top of the placement groove. The arc-shaped plate is located on the side of the stop block near the tunnel entrance of the previous section. The opening of the arc-shaped plate faces away from the placement groove. One end of the arc-shaped plate is fixed to the guide rail, and the other end leaves a gap with the top of the stop block.

[0009] By adopting the above technical solution, when the second jack pushes the tunnel boring machine (TBM) to move to the next section on the guide rail, the TBM moves to the arc plate. The second jack continues to push the TBM to move, and the TBM moves along the surface of the arc plate. Then, the TBM presses the stop block, so that the TBM continues to move to the next section. By setting the arc plate, it is easier for the TBM to move to the stop block and press the stop block, which facilitates the movement of the TBM.

[0010] Optionally, the fixing box is slidably disposed on the guide rail, and the fixing box can slide along the traveling direction of the tunnel boring machine; The shield tunneling translation and air-pushing station-passing device also includes a transmission assembly and a locking assembly. The transmission assembly is located within the placement slot and includes a first rack, a transmission shaft, a first gear, and a second rack. The first rack is horizontally positioned, and its direction is consistent with the tunnel boring machine's travel direction. One end of the first rack is fixed to the side of the fixing box near the bottom wall. The transmission shaft is horizontally positioned below the first rack, and its direction is perpendicular to the tunnel boring machine's travel direction. Both ends of the transmission shaft are rotatably connected to the guide rails. The first gear is coaxially fixed to the transmission shaft and can engage with the first rack. The second rack is horizontally positioned below the first gear and can mesh with it. Its direction is consistent with the tunnel boring machine's travel direction. The end of the second rack away from the first gear is connected to the locking assembly. The locking assembly is located at the connection point of two adjacent guide rails and is used to strengthen the connection between the two adjacent guide rails.

[0011] By adopting the above technical solution, when the second jack passes the stop, the telescopic component extends, the stop moves away from the bottom wall of the fixed box, the second jack presses against the stop, and the second jack is activated, pushing the tunnel boring machine to move. At this time, the second jack generates a counter-thrust force, and the second jack presses against the stop, which can push the stop away from the tunnel boring machine. The fixed box moves synchronously with the stop. During the movement of the fixed box, the fixed box drives the first rack to move. At this time, the first rack drives the first gear to rotate. During the rotation of the first gear, the first gear drives the second rack to move. The second rack pushes the locking component to move. The locking component can strengthen the connection between two adjacent guide rails. By setting the transmission component and the locking component, the stop is pushed by the counter-thrust force generated by the second jack. During the movement of the tunnel boring machine to the next section, the stop can strengthen the connection between two adjacent guide rails through the transmission cooperation of the first rack, the first gear and the second rack.

[0012] Optionally, the snap-fit ​​assembly includes at least one plug-in plate, at least one elastic element, and a snap-fit ​​member. The second rack passes through one of the guide rails and extends into the placement chamber of the other guide rail. The plug-in plate is fixed to one side of the second rack. The elastic element is located between the plug-in plate and the guide rail. One end of the elastic element is fixed to the plug-in plate, and the other end is fixed to the side of the guide rail near the connection point. The snap-fit ​​member is located near the placement chamber of the guide rail and is fixed to the guide rail. The snap-fit ​​member is used to snap the second rack.

[0013] By adopting the above technical solution, when the second jack pushes the stop block to move, the first rack, the first gear, and the second rack can drive the second rack to move. During the movement of the second rack, the second rack moves closer to the placement chamber. At this time, the elastic element is compressed, and the locking element can lock the second rack, which can strengthen the connection between the two adjacent guide rails. When it is necessary to separate the two adjacent guide rails, the operator drives the locking element to separate it from the second rack. At this time, the elastic element returns to its original deformation, and the second rack moves away from the placement chamber, and then the two adjacent guide rails can be separated. By setting the locking element, the second rack can be fixed, which helps to increase the stability of the second rack connection and further strengthens the connection between the two adjacent guide rails.

[0014] Optionally, the telescopic assembly further includes a fixing member located at the bottom of the fixing box. The fixing member includes a fixing rod, which is vertically arranged. One end of the fixing rod is fixed to the bottom of the stop block, and the other end is slidably arranged on the guide rail.

[0015] By adopting the above technical solution, when the second jack pushes the stop block, the fixed box moves synchronously with the stop block. At this time, the fixing rod moves synchronously with the fixed box. On the one hand, by setting the fixing rod, it is beneficial for the fixed box to slide in the placement slot. On the other hand, setting the fixing rod can guide the fixed box.

[0016] Optionally, a guide assembly is also included. The guide assembly is located within the placement slot and includes a rotating rod, a second gear, and a third rack. The rotating rod is horizontally positioned above the second rack, and its direction is perpendicular to the tunnel boring machine's travel direction. The rotating rod is located on the side of the fixing box away from the tunnel entrance. Both ends of the rotating rod are rotatably connected to the guide rail. The second gear is coaxially fixed to the rotating rod and can mesh with the second rack. The third rack is horizontally positioned above the second gear, with one end fixed to the fixing box, and meshes with the second gear.

[0017] By adopting the above technical solution, during the movement of the stop block, the fixed box moves synchronously with the stop block. Through the transmission cooperation of the first rack, the first gear and the second rack, the second rack can be driven to move. During the movement of the second rack, the second rack drives the second gear to rotate. During the rotation of the second gear, the second gear drives the third rack to move. By setting the guide component, it is beneficial to reduce the possibility of the fixed box shaking during the sliding process.

[0018] Optionally, the moving component includes a lower steel plate, an upper steel plate, and a moving part. The lower steel plate is horizontally fixed to the ground, and the upper steel plate is horizontally fixed to the side of the lower steel plate away from the ground. The moving part includes a receiving frame, which is a rectangular frame located on the side of the upper steel plate away from the lower steel plate. The receiving frame is slidably connected to the upper steel plate, and the sliding direction of the receiving frame is perpendicular to the traveling direction of the tunnel boring machine. The receiving frame is used to place the tunnel boring machine.

[0019] By adopting the above technical solution, after the tunnel boring machine (TBM) emerges from the previous tunnel section, it needs to be measured and positioned. After the TBM emerges from the tunnel, it lands on the receiving frame. The receiving frame is then moved horizontally according to the actual position dimensions. At this time, the TBM moves synchronously with the receiving frame, so that the centerline of the TBM is on the centerline of the TBM's transit track. After that, the TBM is pushed to the next section. By setting up the moving components, it is easier to move the TBM horizontally.

[0020] Optionally, one end of the guide rail is provided with two card holders, the card holders are fixed to the guide rail, and the end of the guide rail away from the card holders is fixed with a plug-in socket that fits with the card holder on the other guide rail.

[0021] By adopting the above technical solution, when it is necessary to splice guide rails, by setting up a card holder and a plug-in seat, it is only necessary to insert the plug-in seat on one guide rail into the card holder on another guide rail, so that the plug-in seat and the card holder fit together, which is conducive to the splicing between two adjacent guide rails.

[0022] Optionally, the guide rail has at least one groove at the bottom of the placement slot, the groove being oriented in the same direction as the tunnel boring machine's travel direction. The fixing component also includes a roller, which is located on the side of the fixing rod near the groove. The roller is rotatably connected to the fixing rod and can roll along the length of the groove within the groove.

[0023] By adopting the above technical solution, when the second jack pushes the stop block to move, the fixed box moves synchronously with the stop block. At this time, the fixed rod moves synchronously with the fixed box. Subsequently, the roller can extend into the slide groove and roll along the length of the slide groove. By setting the roller, it is beneficial to the movement of the fixed rod, thereby facilitating the movement of the fixed box in the placement groove.

[0024] Optionally, the support assembly further includes a plurality of first jacks, the bottom of which abuts against the ground and the top of which abuts against the receiving frame, the plurality of first jacks being used to lift the receiving frame.

[0025] By adopting the above technical solution, when it is necessary to lay the guide rail, the personnel move the first jack to the receiving frame, set multiple first jacks in the preset positions, then put one end of the first jack against the ground and the other end against the receiving frame, and start multiple first jacks at the same time. The first jacks lift the receiving frame and then lay the guide rail. By setting the first jacks, it is easier to lay the guide rail.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Compared with related technologies, this application starts the second jack, which pushes the tunnel boring machine to move. During the retraction of the second jack, the second jack passes over the stop block. After that, the second jack only needs to be pressed against the stop block. There is no need to fix the second jack and the guide rail again. The second jack can push the tunnel boring machine to move, which helps to improve the problem of the relatively troublesome empty push operation. 2. By setting up an arc-shaped plate, it is easier for the tunnel boring machine to move to the stop block, press the stop block, and facilitate the movement of the tunnel boring machine; 3. The stop block is pushed by the counter-thrust force generated by the second jack. During the process of the tunnel boring machine moving to the next section, the stop block can strengthen the connection between two adjacent guide rails through the transmission cooperation of the first rack, the first gear and the second rack.

[0042] The implementation principle of the shield tunneling machine translation and empty-push-through-station device in this application embodiment is as follows: After the shield machine 7 comes out of the previous tunnel section, it is necessary to measure and position the shield machine 7 to determine its position. According to the actual position dimensions, the shield machine 7 is translated and its position is adjusted so that the centerline of the shield machine 7 is on the centerline of the shield machine 7 passing through the station track. Then, the shield machine 7 is empty-push-through to the next section.

[0043] When the tunnel boring machine 7 needs to be moved horizontally, the specific process is as follows: Place the horizontal movement cylinder 132 between the receiving frame 131 and the side wall, and then start the horizontal movement cylinder 132 to move the receiving frame 131 and the tunnel boring machine 7 as a whole. The horizontal movement process should be slow and even. Observe whether the receiving frame 131 is deformed. The horizontal movement cylinder 132 moves the receiving frame 131 a certain distance, and then retracts the horizontal movement cylinder 132. Add a steel cylinder or I-beam between the horizontal movement cylinder 132 and the side wall and then move horizontally again. Repeat the operation until the tunnel boring machine 7 is moved to the designated position.

[0044] When it is necessary to push the tunnel boring machine 7 to the next section, firstly, personnel place each of the four first jacks 21 close to a support block 1311, fix the first jacks 21 to the support block 1311, start the first jacks 21 to raise the receiving frame 131 and the tunnel boring machine 7, and then splice two adjacent support members 22 to form a track. At this time, the insertion seat 2212 of the guide rail 221 in one support member 22 is inserted into the locking seat 22 of the guide rail 221 in the other support member 22. 11. Then, the second jack 8 can push the receiving frame 131 to move. The second jack 8 can slide on the guide rail 221. The tunnel boring machine 7 moves synchronously with the receiving frame 131. The receiving frame 131 presses against the stop block 33. The stop block 33 moves towards the bottom wall of the fixed box 31. The telescopic rod 341 shortens and the spring 342 is compressed. At this time, the top of the stop block 33 is flush with the top of the fixed box 31. After the second jack 8 passes the stop block 33, the spring 342 returns to its original deformation, and the telescopic rod 341 extends. Subsequently... The second jack 8 pushes the receiving frame 131 to continue moving along the guide rail 221. The tail of the second jack 8 abuts against the stop block 33. The counterforce generated by the second jack 8 pushes the stop block 33. At this time, the fixing box 31 drives the first rack 41 to move, and the first rack 41 drives the first gear 43 to rotate. Subsequently, the second rack 44 moves with the first gear 43. The second rack 44 moves towards an adjacent guide rail 221. During the movement of the second rack 44, the elastic element 52 is compressed. When the fixed box 31 stops moving, the snap-fit ​​plate 531 extends into the tooth groove of the second rack 44 to fix the second rack 44, which can strengthen the connection between the two adjacent guide rails 221. When the tunnel boring machine 7 and the receiving frame 131 are completely inserted into the second guide rail 221, the first guide rail 221 is no longer under force. At this time, the first guide rail 221 can be disassembled from the connection point, moved to the connection point of the front guide rail 221, and connected to it. Repeat the operation until the tunnel boring machine 7 is pushed through empty.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
