Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine transportation technology, specifically to a tunnel boring machine dismantling and transportation device that can be moved inside the tunnel. Background Technology

[0002] With the widespread application of tunnel boring machines (TBMs) in tunnel construction, their dismantling and transportation after use have received increasing attention. After completing their construction tasks, TBMs need to have their main components disassembled and transported to designated locations using appropriate transportation equipment for subsequent maintenance, storage, or reuse.

[0003] Currently, the commonly used track trolleys for dismantling and transporting tunnel boring machines (TBMs) have many drawbacks. On the one hand, when placing the mechanical components of the TBM, the lack of an effective limiting and fixing structure makes the mechanical components prone to displacement during the movement of the track trolley. This can not only cause collisions and friction between the mechanical components, leading to surface damage and affecting the quality and subsequent performance of the mechanical components, but also pose certain safety hazards and may cause accidents.

[0004] On the other hand, existing track slab vehicles often lack the ability to lift and secure mechanical components. When dismantling a tunnel boring machine (TBM), workers find it difficult to flexibly adjust the height of mechanical components according to actual needs for convenient dismantling, making the entire process cumbersome and time-consuming, thus reducing work efficiency. Furthermore, the inability to effectively secure components compromises stability during transportation, increasing transport risks.

[0005] Given the obvious shortcomings of these existing dismantling and transportation devices, there is an urgent need for a tunnel boring machine (TBM) dismantling and transportation device that can move inside the tunnel to overcome the above-mentioned defects and ensure that the TBM dismantling and transportation work can be carried out efficiently and safely. Utility Model Content

[0006] To address the technical problems mentioned above, this invention provides a tunnel boring machine dismantling and transportation device that can be moved inside the tunnel.

[0007] This utility model adopts the following technical solution: a tunnel boring machine dismantling and transportation device that can move inside a tunnel, including a mobile vehicle body; and further including:

[0008] A lifting assembly is mounted on the mobile vehicle body; a transport platform is provided at the output end of the lifting assembly.

[0009] A positioning clamp assembly is disposed on the transport table; the positioning clamp assembly has two sets of positioning plates arranged opposite each other, and the two sets of positioning plates have a reciprocating degree of freedom in the lateral direction;

[0010] Two sets of lifting clamp assemblies are connected to the outside of the positioning plate; each set of lifting clamp assemblies has a lifting plate that is arranged opposite to each other, and the lifting plate has a reciprocating degree of freedom in the vertical direction;

[0011] At least two sets of anti-displacement components are assembled between the transport platform and the mobile vehicle body and located at the edge; during transfer, the anti-displacement components are in a retracted state, and during loading, the anti-displacement components are in an extended state acting on the surrounding carrier.

[0012] In a further embodiment, the lifting assembly consists of at least four sets of cylinders, each fixed to the mobile vehicle body; the output end of the cylinder is connected to the transport platform.

[0013] In a further embodiment, the transport platform has a first groove in a predetermined direction; the positioning clamp assembly includes:

[0014] The first forward and reverse motor is installed on the inner wall of the first slide groove;

[0015] A first bidirectional threaded rod is rotatably mounted in the first slide groove; one end of the first bidirectional threaded rod is connected to the output shaft of the first forward and reverse motor.

[0016] Two sets of first threaded blocks are slidably disposed at both ends of the first bidirectional threaded rod; the two sets of first threaded blocks are respectively connected to the two sets of positioning plates.

[0017] In a further embodiment, the lifting clamp assembly includes:

[0018] A guide rod is fixed to the outside of the corresponding positioning plate; a second sliding groove is provided inside the guide rod;

[0019] The second forward and reverse motor is installed on the inner wall of the second slide groove;

[0020] A one-way threaded rod is rotatably mounted in the second slide groove; one end of the one-way threaded rod is connected to the output shaft of the second forward and reverse motor.

[0021] The second threaded block is slidably mounted on the one-way threaded rod; the second threaded block is used to fix the lifting plate.

[0022] In a further embodiment, the anti-displacement component includes:

[0023] A limiting block is fixed on the moving vehicle body; the limiting block has a predetermined length, and its upper surface is recessed from top to bottom to form a third sliding groove.

[0024] The third forward and reverse motor is installed on the inner wall of the third slide groove;

[0025] The second bidirectional threaded rod is rotatably mounted in the third slide groove; one end of the second bidirectional threaded rod is connected to the output shaft of the third forward and reverse motor.

[0026] Two sets of third threaded blocks are slidably disposed at both ends of the second bidirectional threaded rod; the two sets of third threaded blocks are respectively connected to support members.

[0027] In a further embodiment, the clamping surface of the positioning plate is provided with a plurality of protrusions.

[0028] In a further embodiment, the support member includes: a connecting rod with one end connected to a third threaded block, the connecting rod having a predetermined length;

[0029] The other end of the connecting rod is connected to a support block.

[0030] In a further embodiment, the support surface of the support block is provided with a plurality of protrusions.

[0031] The beneficial effects of this utility model are as follows: By setting at least two sets of anti-displacement components, which are in a retracted state during transport and in an extended state during loading, this ingenious design can effectively limit the movement of the transport platform (device) relative to the surrounding carrier (such as the ground inside the tunnel) when the device loads the mechanical parts of the tunnel boring machine. This provides a stable foundation for the entire transportation process, greatly reduces the possibility of mechanical parts colliding and rubbing against each other due to shaking and displacement during transportation, ensures that the mechanical parts can be transported to the designated location in good condition, protects the integrity of the mechanical parts and their subsequent performance, and reduces maintenance costs and potential safety hazards caused by displacement.

[0032] Secondly, the positioning clamp assembly has two sets of positioning plates that are relatively set and have a degree of freedom to move back and forth in the lateral direction. When placing the mechanical parts of the tunnel boring machine, the spacing between the positioning plates can be flexibly adjusted according to the size of the mechanical parts to accurately position the mechanical parts laterally, so that they can maintain an accurate position on the transport platform. This further prevents the mechanical parts from shifting laterally during transportation. In conjunction with the anti-displacement component, it comprehensively ensures the stability of the mechanical parts during placement.

[0033] Furthermore, the two sets of lifting clamp assemblies configured on the outer side of the positioning plate have vertical freedom of movement. When disassembling the tunnel boring machine (TBM), workers can flexibly adjust the height of mechanical components using these assemblies, facilitating their removal from the TBM and placement on the transport platform. Alternatively, when unloading mechanical components, they can be adjusted to a suitable height for unloading operations, avoiding the hassle of extra manpower and time spent on handling or adjustment due to unsuitable height. This significantly improves the convenience and efficiency of disassembly and unloading. During transport, the lifting plates can also be pressed against the mechanical components located between the positioning plates to provide some restraint and prevent slippage during transport.

[0034] Finally, the transport platform is connected to the mobile vehicle body through a lifting assembly. The lifting assembly (such as at least four sets of cylinders) can stably realize the lifting function of the transport platform. This allows the entire transport device to easily adapt to different working scenarios (such as the height difference between the shield machine dismantling position and storage position). Whether during initial loading or final unloading of mechanical parts, the height of the transport platform can be adjusted to make the operation smoother, further shortening the overall time of dismantling and transporting and improving work efficiency.

Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] Example 1

[0042] like Figure 1 As shown, this embodiment discloses a tunnel boring machine dismantling and transportation device that can move within a tunnel, including a mobile vehicle body 1 for transporting and dismantling mechanical components. Furthermore, a lifting assembly is provided on the mobile vehicle body 1. This embodiment uses four sets of equally spaced cylinders 3 as an example, and a transport platform 2 is simultaneously connected to the output end of each cylinder 3. Therefore, the transport platform 2 serves as the carrier for transport.

[0043] It is worth noting that the cylinder 3 is added between the transport platform 2 and the mobile vehicle 1 to meet the height requirements during disassembly, transfer, and unloading processes, reduce the intensity of manual operation, and improve the safety factor.

[0044] Furthermore, the transport platform 2 is equipped with a positioning clamp assembly 4, which has two sets of positioning plates 405 arranged opposite to each other. The two sets of positioning plates 405 have a reciprocating degree of freedom in the lateral direction. In other words, the positioning and clamping of mechanical parts of different volumes and numbers can be achieved by the two sets of positioning plates 405 that can move in opposite directions.

[0045] Meanwhile, to better support disassembled mechanical parts at height and to constrain and limit the height of mechanical parts between the two sets of positioning plates 405 during transportation, thereby increasing stability, a lifting clamp assembly 5 is also provided on the positioning plate 405. Each lifting clamp assembly 5 has a lifting plate 506 arranged opposite to each other, and the lifting plate 506 has a reciprocating degree of freedom in the vertical direction.

[0046] In other words, the two sets of positioning plates 405 of the lifting clamp assembly 5 and the two sets of positioning plates 405 of the positioning clamp assembly 4 do not interfere with each other in space. Specifically, this can be achieved by combining... Figure 1 Considering that the loading process will exert forces on the shield machine's disassembly and transportation device, uncontrollable movement of the device may occur. Therefore, to solve this technical problem, this embodiment also includes: at least two sets of anti-displacement components 6, disposed between the transport platform 2 and the moving vehicle 1 and located at the edge; during transfer, the anti-displacement components 6 are in a retracted state, and during loading, the anti-displacement components 6 are in an extended state acting on the surrounding carrier.

[0047] In a further embodiment, in order to set the positioning clamp assembly 4, such as Figure 2As shown, the transport platform 2 has a first chute 402 in a predetermined direction. Based on the above structure, the positioning clamp assembly 4 includes: a first forward / reverse motor 401 installed on the inner wall of the first chute 402, and a rotatable first bidirectional threaded rod 403 installed in the first chute 402. One end of the first bidirectional threaded rod is connected to the output shaft of the first forward / reverse motor 401. Correspondingly, two sets of first threaded blocks 404 are slidably arranged at both ends of the first bidirectional threaded rod 403, and the two sets of first threaded blocks 404 are respectively connected to the two sets of positioning plates 405. In order to increase friction and improve safety, the clamping surface of the positioning plate 405 is provided with a plurality of protrusions 406.

[0048] Therefore, when it is necessary to position and clamp the components of the tunnel boring machine, the first forward and reverse motor 401 is started. If the first forward and reverse motor 401 rotates forward, its output shaft drives the first bidirectional threaded rod 403 connected to it to rotate. Since the first bidirectional threaded rod 403 has a bidirectional threaded structure, when it rotates, the first threaded blocks 404 at both ends will move in opposite directions (i.e., towards each other) along the first bidirectional threaded rod 403 under the action of the threads. Because the two sets of first threaded blocks 404 are respectively connected to two sets of positioning plates 405, the two sets of positioning plates 405 will also move towards each other along with the first threaded blocks 404, gradually approaching the tunnel boring machine components, and finally achieving the clamping and positioning of the components, ensuring that the components remain stable on the transport platform 2 and do not undergo lateral displacement.

[0049] When it is necessary to loosen the parts, the first forward and reverse motor 401 is reversed. At this time, the first bidirectional threaded rod 403 rotates in the opposite direction, and the first threaded blocks 404 at both ends move in the opposite direction (i.e., in reverse) along the first bidirectional threaded rod 403. The two sets of positioning plates 405 also gradually move away from the parts as the first threaded blocks 404 move in the opposite direction, thereby loosening the clamping on the parts and facilitating the loading and unloading of the parts.

[0050] Combination Figure 3 The lifting clamp assembly 5 includes: a guide rod 501 fixed to the outer wall of the positioning plate 405, with a second slide groove 502 provided inside the guide rod 501. It also includes: a second forward / reverse motor 503 installed on the inner wall of the second slide groove 502, and a one-way threaded rod 504 rotatably installed within the second slide groove 502, one end of which is connected to the output shaft of the second forward / reverse motor 503. A second threaded block 505 is slidably disposed on the one-way threaded rod 504, and the second threaded block 505 is used to fix the lifting plate 506.

[0051] That is, the height position of the lifting plate 506 is controlled by the second forward and reverse motor 503, which satisfies the height requirement, and the lifting clamp assembly 5 moves laterally along with the positioning plate 405.

[0052] like Figure 4 As shown, the anti-displacement component 6 includes: a limiting block 601 fixed on the moving vehicle body 1, combined with... Figure 4 The limiting block 601 has a predetermined length, and its upper surface is recessed from top to bottom to form a third groove 602.

[0053] A third forward / reverse motor 603 is installed inside the third slide groove 602, and a rotatable second bidirectional threaded rod 604 is provided. One end of the second bidirectional threaded rod 604 is connected to the output shaft of the third forward / reverse motor 603.

[0054] Correspondingly, two sets of third threaded blocks 605 are slidably disposed at both ends of the second bidirectional threaded rod 604, and the two sets of third threaded blocks 605 are respectively connected to support members 606. Its working principle can be referred to the positioning clamp assembly 4 above.

[0055] Furthermore, considering the size of the space inside the cave, the support member 606 includes: a connecting rod 606-a connected at one end to the third threaded block 605, the connecting rod 606-a having a predetermined length; and a support block 606-b connected at the other end of the connecting rod 606-a (which can be fixedly connected or hinged; if hinged, it can be applied to different shaped spatial surfaces). Several protrusions 606-c are provided on the support surface of the support block 606-b to increase friction.

[0056] Placing mechanical components: After the anti-displacement assembly secures the moving vehicle body, the transport platform is lifted to the designated height using a cylinder. At this point, the lifting plate inside the lifting clamp assembly is at its highest relative position, allowing the mechanical components to be placed. Subsequently, the lifting plate, carrying the mechanical components, returns to its original position at the bottom.

[0057] Positioning the mechanical component: The first forward and reverse motor is started to rotate forward, and the positioning plates move towards each other to position and clamp the mechanical component. Then, the first bidirectional threaded rod is driven by the first forward and reverse motor, and the positioning plates drive the lifting clamp assembly to move outward, releasing the restriction on the bottom of the mechanical component.

[0058] Repeated placement and positioning: Repeat the above placement and positioning steps to place multiple mechanical parts between the two positioning plates in sequence, and clamp them by the first forward and reverse motor.

[0059] Adjusting and fixing the height: After reaching a certain position, control the second forward and reverse motor to move the lifting plate upward to the top of the mechanical component. Then, control the cylinder to move the fixing component, lifting and positioning component, and mechanical component downward to the designated position. Then, control the corresponding motor to adjust the position of the limit seat and fixing clamp to fix the top and sides of the mechanical component.

[0060] Release the limit and transport: Finally, turn on the motor to drive the connecting rod and the limit clamp to move, releasing the limit on the moving vehicle body, and transport the mechanical parts to the designated location via the moving vehicle body. The above description is only a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
