Description

Technical Field

[0001] This utility model relates to the technical field of tunneling equipment for soil or rock strata, and specifically to a TBM hoisting and transportation system for inclined shafts. Background Technology

[0002] In recent years, the construction scale and speed of pumped storage power stations in my country have both grown rapidly. During this process, the problems and shortcomings of traditional construction methods have become increasingly apparent, especially in water conveyance tunnels. The safety and progress issues in the construction of ultra-large inclination angles and multi-stage long inclined shaft sections have become urgent problems to be solved in engineering construction. Using inclined shaft TBMs (tunnel boring machines) for excavation can effectively achieve "mechanization replacing manpower, automation improving efficiency, and intelligent construction." However, because inclined shaft TBMs excavate upwards under large inclination angles, the transportation of materials and personnel is a key factor restricting construction efficiency. Traditional inclined shaft transportation often uses a unidirectional winch hoisting system, requiring the unidirectional winch to be fixed to the equipment. Under the limited space of the TBM equipment, traditional transportation systems cannot achieve coordination between equipment installation and tunneling operations, and do not conform to the lightweight design of inclined shaft TBMs.

[0003] Chinese patent document with application number 202221033529.X discloses an inclined shaft tunneling machine, specifically disclosing a main unit, a rear-mounted trailer group, and a transportation system for transporting personnel and / or materials to the rear-mounted trailer group. The transportation system includes a transport vehicle and a drive unit. The rear-mounted trailer group is equipped with a material transfer device for transferring materials between the transport vehicle and the main unit. The transport vehicle is a railcar. The drive unit includes a power unit, a drive gear connected to the power unit, and a geared rail laid along the tunnel extension direction at the bottom of the tunnel and meshing with the drive gear. The power unit and the drive gear are mounted on the transport vehicle. The transport system of this inclined shaft tunneling machine does not require periodic adjustment of the position of the redirecting wheels, thus solving the problem of low construction efficiency caused by the inconvenience of the material transport system in existing inclined shaft tunneling machines. However, this inclined shaft tunneling machine has the following shortcomings: 1) The transport vehicle moves along the inclined shaft by meshing with the drive gear and the rack. On the one hand, the rack needs to be laid along the inclined shaft and lengthens as the inclined shaft grows, resulting in high manufacturing costs. On the other hand, laying the rack requires consideration of the matching position with the drive gear, which is difficult and takes up a lot of construction time, affecting construction efficiency; 2) The power unit and drive gear need to be installed on the transport vehicle, which increases the load on the transport vehicle and affects its carrying capacity and efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an inclined shaft TBM hoisting and transportation system that is easy to construct, conducive to improving construction efficiency, reduces the load on the transport vehicle, and increases the carrying capacity and efficiency of the transport vehicle.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A TBM hoisting and transportation system for inclined shafts includes a horizontal tunnel and an inclined tunnel, with the rear end of the inclined tunnel connected to the front end of the horizontal tunnel. The system includes a hoisting winch, a recovery winch, an inclined shaft TBM, a transport vehicle, a hoisting traction rope, and a recovery traction rope. The hoisting winch and recovery winch are both located at the end of the horizontal tunnel away from the inclined tunnel. The inclined shaft TBM is located at the front end of the inclined tunnel. A reversing pulley is provided at the rear end of the inclined shaft TBM. The transport vehicle is located inside the inclined shaft and between the inclined shaft TBM and the hoisting and recovery winches. One end of the hoisting traction rope is connected to the hoisting winch, and the other end passes around the reversing pulley and connects to the front end of the transport vehicle. One end of the recovery traction rope is connected to the recovery winch, and the other end is connected to the rear end of the transport vehicle.

[0007] As a further improvement to the above technical solution:

[0008] A pressure roller is provided at the bottom of the junction of the flat tunnel and the inclined tunnel, and the lifting traction rope is threaded below the pressure roller.

[0009] The bottom of the inclined tunnel is provided with a plurality of first support wheels arranged at intervals along the extension direction, and the lifting traction rope is supported on the first support wheels.

[0010] The bottom of the tunnel is provided with multiple second support wheels arranged at intervals along the extension direction, and the lifting traction rope is supported on the second support wheels.

[0011] The bottom of the inclined shaft is equipped with a bottom rail, and the transport vehicle is supported on the bottom rail.

[0012] The recovery winch is located in the extension direction of the bottom rail, and the lifting winch is located to the side in the extension direction of the bottom rail.

[0013] The inclined tunnel behind the TBM is equipped with multiple gantry frames arranged at intervals along the extension direction, and the lifting traction rope is threaded through each gantry frame.

[0014] The top of the gantry frame is equipped with limit wheels.

[0015] The lifting traction rope is detachably connected to the transport vehicle.

[0016] The recovery traction rope is detachably connected to the transport vehicle.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This utility model discloses a TBM (Tunnel Boring Machine) hoisting and transportation system for inclined shafts. The hoisting traction rope bypasses a reversing pulley and connects to the front end of the transport vehicle. As the TBM advances in the inclined shaft, the hoisting traction rope extends accordingly, maintaining its alignment with the reversing pulley. Inside the horizontal tunnel, workers load materials into the transport vehicle. The hoisting winch then retracts the hoisting traction rope, moving the transport vehicle along the inclined shaft to the TBM, thus supplying materials to the TBM. At this time, workers can also load items from the TBM into the inclined shaft. The hoisting winch then lowers the transport vehicle into the horizontal tunnel, and the recovery winch retracts the vehicle, moving it along the horizontal tunnel to the designated location. This inclined shaft TBM hoisting and transportation system utilizes the hoisting and unwinding actions of hoisting and recovery winches, or their coordinated hoisting and unwinding actions, to move transport vehicles along the inclined shaft for material transport. Compared to existing systems that use drive gears and toothed rails to move transport vehicles along the inclined shaft, this system offers several advantages: lower manufacturing costs, easier construction, and improved construction efficiency. Furthermore, the transport vehicles do not require a power unit, reducing their load and increasing their carrying capacity and efficiency. Attached Figure Description

[0032] Figures 1 to 7This invention illustrates an embodiment of the inclined shaft TBM hoisting and transportation system. The inclined shaft 7 includes a horizontal tunnel 71 and an inclined tunnel 72, with the rear end of the inclined tunnel 72 connected to the front end of the horizontal tunnel 71. The system includes a hoisting winch 1, a recovery winch 2, an inclined shaft TBM 3, a transport vehicle 4, a hoisting traction rope 5, and a recovery traction rope 6. The hoisting winch 1 and the recovery winch 2 are both located at the end of the horizontal tunnel 71 away from the inclined tunnel 72. The inclined shaft TBM 3 is located at the front end of the inclined tunnel 72, and a reversing pulley 8 is provided at the rear end of the inclined shaft TBM 3. The transport vehicle 4 is located inside the inclined shaft 7 and between the inclined shaft TBM 3 and the hoisting winch 1 and the recovery winch 2. One end of the hoisting traction rope 5 is connected to the hoisting winch 1, and the other end passes around the reversing pulley 8 and connects to the front end of the transport vehicle 4. One end of the recovery traction rope 6 is connected to the recovery winch 2, and the other end is connected to the rear end of the transport vehicle 4.

[0033] In this inclined shaft TBM hoisting and transportation system, the hoisting traction rope 5 is connected to the front end of the transport vehicle 4 by passing around the reversing pulley 8. As the inclined shaft TBM3 advances, the hoisting traction rope 5 also extends, maintaining its alignment with the reversing pulley 8. Inside the horizontal tunnel 71, construction workers load materials into the transport vehicle 4. The hoisting winch 1 then activates to retract the hoisting traction rope 5, moving the transport vehicle 4 along the inclined shaft 7 to the inclined shaft TBM3, thus transporting materials to the inclined shaft TBM3. At this time, items on the inclined shaft TBM3 can also be loaded into the inclined shaft TBM3 by construction workers. Then, the hoisting winch 1 lowers the transport vehicle 4 to the horizontal tunnel 71, and the recovery winch 2 retracts the transport vehicle 4, moving it along the horizontal tunnel 71 to the designated location. This inclined shaft TBM hoisting and transportation system uses the hoisting winch 1 and the recovery winch 2, or the combined hoisting winch 1 and the recovery winch 2, to move the transport vehicle 4 along the inclined shaft 7 for material transport. Compared with the existing system that uses a drive gear and a toothed rail to move the transport vehicle 4 along the inclined shaft 7, this system has lower manufacturing costs and lower construction difficulty, which is conducive to improving construction efficiency. Furthermore, the transport vehicle 4 does not need to be equipped with a power unit, which reduces the load on the transport vehicle 4 and increases its carrying capacity and efficiency.

[0034] Furthermore, in this embodiment, as Figure 1 As shown, a pressure roller 9 is provided at the bottom of the junction of the horizontal tunnel 71 and the inclined tunnel 72, and the lifting traction rope 5 is threaded below the pressure roller 9. The lifting traction rope 5 is threaded below the pressure roller 9 to prevent the lifting traction rope 5 from moving up to the upper part of the inclined shaft 7 when it is under tension, thus affecting the passage of the transport vehicle 4.

[0035] Furthermore, in this embodiment, the bottom of the inclined tunnel 72 is provided with a plurality of first support wheels 721 arranged at intervals along the extension direction, and the lifting traction rope 5 is supported on the first support wheels 721. The lifting traction rope 5 can be supported on the first support wheels 721, which helps to prevent it from falling to the bottom of the inclined tunnel 72, thereby avoiding the influence of the bottom slag on the lifting traction rope 5.

[0036] Furthermore, such as Figure 5 and Figure 6 As shown, in this embodiment, the bottom of the horizontal tunnel 71 is provided with a plurality of second support wheels 711 arranged at intervals along the extension direction, and the lifting traction rope 5 is supported on the second support wheels 711. The lifting traction rope 5 is supported on the second support wheels 711, which helps to prevent it from falling to the bottom of the horizontal tunnel 71, thereby avoiding the influence of the bottom slag on the lifting traction rope 5.

[0037] Furthermore, such as Figure 5 and Figure 6 As shown, in this embodiment, the bottom of the inclined shaft 7 is provided with a bottom rail 712, and the transport vehicle 4 is supported on the bottom rail 712, which facilitates the movement of the transport vehicle 4 along the inclined shaft 7.

[0038] Furthermore, such as Figure 6 As shown, in this embodiment, the recovery winch 2 is located in the extending direction of the bottom rail 712, and the lifting winch 1 is located to the side in the extending direction of the bottom rail 712. This prevents interference between the lifting traction rope 5 and the recovery traction rope 6.

[0039] Furthermore, such as Figure 2 and Figure 7 As shown, in this embodiment, the inclined tunnel 72 behind the inclined shaft TBM3 is equipped with multiple gantry frames 722 arranged at intervals along the extension direction, and the lifting traction rope 5 is threaded through each gantry frame 722. The gantry frame 722 can limit the upward movement of the lifting traction rope 5, preventing the lifting traction rope 5 from moving too far upward and affecting the passage of the transport vehicle 4.

[0040] Furthermore, in this embodiment, a limiting wheel 723 is provided at the top of the gantry frame 722. This prevents the lifting traction rope 5 from directly rubbing against the top of the gantry frame 722 when it is taut, thereby reducing wear on the lifting traction rope 5.

[0041] Furthermore, in this embodiment, the lifting traction rope 5 is detachably connected to the transport vehicle 4, such as via a conventional hook (not shown in the accompanying drawings). The retrieval traction rope 6 is also detachably connected to the transport vehicle 4, such as via a conventional hook (not shown in the accompanying drawings). This facilitates rope replacement and transport vehicle 4 changeover.

[0042] Furthermore, in this embodiment, the junction of the flat hole 71 and the inclined hole 72 is connected by an arc-shaped hole, and the pressing wheel 9 is located at the bottom of the arc-shaped hole, and multiple wheels can be set at intervals along the extension direction of the arc-shaped hole.

[0043] In other embodiments, at least two reversing pulleys 8 are provided at the rear end of the inclined shaft TBM3, which are spaced apart along the width direction of the inclined shaft TBM3. This can isolate the distance between the two parallel sections of the lifting traction rope 5 and the horizontal distance between the lifting traction rope 5 and the recovery traction rope 6, thus preventing rope interference.

[0044] 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.
