Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, and in particular to a transverse translation construction structure for a multi-hole steel rail guided shield machine. Background Technology

[0002] Tunnel boring machines (TBMs) are large-scale excavation equipment widely used in tunnel engineering projects such as subways, highways, and railways. In many projects, such as the construction of parallel double-track tunnels, after a TBM completes the excavation of one track, it needs to be precisely moved laterally from the arrival shaft to the starting position of the next tunnel to begin new excavation work. Due to the TBM's enormous size and extreme weight, its lateral movement is a critical process with high technical difficulty and significant safety risks.

[0003] Currently, achieving lateral translation of tunnel boring machines (TBMs) typically relies on large hydraulic translation frames or multiple sets of hydraulic jacks moving synchronously. While these solutions can provide sufficient thrust, they generally suffer from an inherent structural problem. To achieve translation distances of tens of meters, these devices either require hydraulic cylinders with extremely long strokes or complex synchronization control systems. Long-stroke hydraulic equipment is not only expensive to manufacture and structurally bulky, but also places extremely demanding demands on the space available at the construction site. Furthermore, the installation and commissioning processes are quite complex, significantly increasing preparation time and costs.

[0004] More importantly, this "one-time" long-stroke propulsion approach lacks flexibility and economy. It requires the drive mechanism's stroke to be greater than or equal to the total translation distance, resulting in redundant equipment functions and a lack of standardization. Therefore, existing technologies generally lack a construction scheme that can utilize standardized, short-stroke drive units through a clever mechanical structure to achieve long-distance, high-precision, step-by-step translation. This makes the lateral translation process of the tunnel boring machine a persistent challenge in the construction cycle, resulting in high costs and low efficiency.

[0005] Therefore, this utility model proposes a transverse translation construction structure for a multi-hole rail-guided tunnel boring machine to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing technology of shield machine lateral translation construction structure, such as reliance on large long-stroke drive device, resulting in complex overall structure, high cost and inability to flexibly adapt to different translation distances, this utility model aims to provide a multi-hole steel rail guided shield machine lateral translation construction structure with improved structure that can effectively solve the above problems.

[0007] This utility model provides a transverse translation construction structure for a multi-hole rail-guided tunnel boring machine, including: a guide rail, a slide plate movably mounted on the guide rail, and a pushing mechanism.

[0008] The actuation mechanism includes a movable seat, a fixed component, a hydraulic cylinder, and a connecting block.

[0009] Furthermore, the movable seat is detachably fixed to the ground on one side of the guide rail by a fixing component. One end of the hydraulic cylinder is connected to the movable seat, and its driving end abuts against the connecting block. The connecting block is used to push the slide plate to move laterally along the guide rail.

[0010] Preferably, the construction structure further includes a conveying component, which is mounted on a guide rail and includes multiple conveying rollers, with the slide plate supported on the guide rail by the conveying rollers.

[0011] Preferably, the pushing mechanism further includes a U-shaped groove plate, which is fixed to the side of the slide plate, and the connecting block slides with the U-shaped groove plate.

[0012] Preferably, the pushing mechanism further includes a pull plate and a limiting rod, the limiting rod passing through the pull plate, the connecting block and the U-shaped groove plate to detachably fix the connecting block and the U-shaped groove plate.

[0013] Preferably, the fixing component includes a plug rod and a plurality of sockets, the plurality of sockets being spaced apart along the length of the guide rail, the plug rod passing through the movable seat and being selectively inserted into any of the sockets.

[0014] Preferably, the construction structure further includes a dismantling mechanism, which includes multiple ground-inserting rods, with guide rails detachably connected to the ground-inserting rods.

[0015] Preferably, the disassembly mechanism further includes an L-shaped groove and an L-shaped plate. The L-shaped groove is disposed on the grounding rod, and the L-shaped plate is fixed to the bottom of the guide rail. The guide rail is connected to the grounding rod through the sliding fit between the L-shaped plate and the L-shaped groove.

[0016] Preferably, the movable seat can move along the length direction of the guide rail.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a periodically fixed and movable pushing mechanism, uses the extension and retraction of hydraulic cylinders to push the slide plate carrying the tunnel boring machine to move laterally in a step-by-step manner, solves the problem that the existing technology requires large, long-stroke drive devices for translating tunnel boring machines, resulting in high equipment costs, complex structures and low control precision. It achieves the technical effect of compact structure, precise and controllable translation and high degree of automation.

[0019] 2. This utility model solves the problem in the prior art that the length of the translation track is fixed, which cannot flexibly adapt to different translation distances, resulting in material waste and poor site adaptability. By designing the guide rail as a modular structure that is fixed and disassembled by inserting rods and L-shaped plate grooves, the present invention achieves the technical effect of being able to easily splice and extend the track, saving materials, and significantly improving construction flexibility and equipment reusability.

[0020] 3. This utility model reduces moving friction by setting conveyor rollers and provides stable support for guide rails and pushing mechanisms by using ground-inserting rods and fixing components. It solves the problems of high friction, unstable process and easy deviation when heavy equipment is moved in the prior art, and achieves the technical effects of saving effort, running smoothly, guiding accurately and being safe and reliable throughout the entire translation process.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides a multi-hole rail-guided shield machine lateral translation construction structure, which aims to solve the problems of complex lateral translation structure of shield machines, difficulty in controlling translation accuracy, and poor adaptability caused by fixed guide rail length in the prior art.

[0030] like Figure 1 and Figure 2 As shown, the transverse translation construction structure of the multi-hole rail-guided tunnel boring machine includes a guide rail 31 and a slide plate 1 movably mounted on the guide rail 31. The slide plate 1 supports the tunnel boring machine body 2. To reduce friction during movement, a conveying assembly 32 is also provided on the guide rail 31. The conveying assembly 32 includes multiple conveying rollers 321, and the bottom surface of the slide plate 1 is supported on these conveying rollers 321. The core of this construction structure is a pushing mechanism 4 capable of step-by-step translation. The pushing mechanism 4 includes a movable base 41 as the installation base, a fixing assembly 42 for temporarily fixing the movable base 41, a hydraulic cylinder 43 providing power, and a... A connecting block 44 for transmitting thrust, and a fixing component 42 including a rod 421 and a plurality of holes 422 arranged on the ground at intervals along the length of the guide rail 31. When it is necessary to push the slide plate 1, the rod 421 passes through the moving seat 41 and inserts into one of the holes 422, thereby detachably fixing the moving seat 41 to the ground on one side of the guide rail 31. One end of the hydraulic cylinder 43 is fixedly connected to the moving seat 41, and its driving end abuts against the connecting block 44. When the hydraulic cylinder 43 extends, its driving end pushes the connecting block 44, and the connecting block 44 pushes the slide plate 1, thereby driving the slide plate 1 to carry the shield machine body 2 to move a step distance along the direction of the guide rail 31.

[0031] To achieve precise thrust transmission and control, the pushing mechanism 4 in this embodiment also includes a U-shaped groove plate 45, and the U-shaped groove plate 45 forms a specific structural fit and connection relationship with the aforementioned slide plate 1 and connecting block 44.

[0032] Please refer to the following carefully. Figure 1 and Figure 4 The following is a detailed description of the core thrust transmission structure: The U-shaped groove plate 45 is a plate-shaped structure with a U-shaped cross-section groove. It is fixed to the side of the slide plate 1 that needs to bear force by welding or bolting. The function of the U-shaped groove plate 45 is to provide a stable sliding fit interface for the connecting block 44 and bear the thrust transmitted by it. At the same time, the connecting block 44 is provided with a sliding part that matches the shape and size of the groove of the U-shaped groove plate 45. In the assembled state, the sliding part of the connecting block 44 slides in the U-shaped groove of the U-shaped groove plate 45. This sliding fit structure ensures that the connecting block 44 can stably transmit thrust without lateral slippage when pushing the slide plate 1.

[0033] To lock the connecting block 44 and the U-shaped channel plate 45 together during the non-pushing phase and to quickly separate them when needed, the pushing mechanism 4 also includes a pull plate 46 and a limiting rod 47. The pull plate 46 has a through hole, and the side walls of the connecting block 44 and the U-shaped channel plate 45 also have corresponding through holes. The limiting rod 47 passes through the through holes on the pull plate 46, the connecting block 44, and the U-shaped channel plate 45 in sequence, thereby detachably fixing the connecting block 44 and the U-shaped channel plate 45 together. This fixing method has a simple structure and is easy to operate.

[0034] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0035] As a preferred embodiment, to achieve flexible laying and stable fixing of the guide rail 31, please refer to... Figure 2 and Figure 3 The construction structure also includes a dismantling mechanism 3, which includes multiple ground-inserting rods 33 for inserting into the soil to provide a stable base. A guide rail 31 is detachably connected to the ground-inserting rods 33.

[0036] As a further optimization of the disassembly mechanism 3 described above, in order to achieve rapid disassembly and assembly, please refer to... Figure 3 The disassembly mechanism 3 also includes an L-shaped groove 34 and an L-shaped plate 35. The L-shaped groove 34 is integrally formed or fixedly connected to the top of each grounding rod 33, while the L-shaped plate 35 is fixed to the bottom of the guide rail 31. The guide rail 31 forms a sliding fit with the L-shaped groove 34 at the top of the grounding rod 33 through the L-shaped plate 35 at its bottom, thus conveniently connecting to the grounding rod 33. This structure makes the splicing and extension operation of the guide rail 31 very efficient.

[0037] As a preferred design for the actuating mechanism 4, in order to achieve reliable fixing and flexible displacement of the movable seat 41, please refer to... Figure 1 The fixing component 42 specifically includes a plug rod 421 and multiple insertion holes 422. The multiple insertion holes 422 are arranged at intervals along the length of the guide rail 31 and are preset on the ground. The movable seat 41 has a through hole that matches the plug rod 421. The plug rod 421 passes through the through hole of the movable seat 41 and can be selectively inserted into any corresponding insertion hole 422 on the ground, thereby completing the positioning and locking of the movable seat 41.

[0038] In another preferred embodiment, in order to achieve automatic reset of the pushing mechanism 4, the bottom of the movable seat 41 is provided with a slider or roller so that it can move along the length direction of the guide rail 31. When the hydraulic cylinder 43 retracts, the movable seat 41, which is not fixed by the fixing component 42, can be pulled forward under the reaction force to prepare for the next step push.

[0039] The implementation principle of this embodiment is as follows: When performing lateral translation, the tunnel boring machine body 2 is first placed on the slide plate 1, which is then placed on a moving track composed of guide rail 31 and conveying roller 321. When operating the pushing mechanism 4, the insertion rod 421 is first passed through the moving seat 41 and inserted into a hole 422 on the ground to firmly fix the moving seat 41. Then, the connecting block 44 is locked to the U-shaped groove plate 45 fixed on the side of the slide plate 1 by the pull plate 46 and the limiting rod 47.

[0040] Hydraulic cylinder 43 is activated to extend it. The drive end of hydraulic cylinder 43 pushes connecting block 44. Since the moving seat 41 is fixed and cannot move backward, the thrust is completely transmitted to the carriage 1 through connecting block 44 and U-shaped channel plate 45, driving carriage 1 to carry the tunnel boring machine body 2 to move laterally one step distance along the direction of guide rail 31. After one step is completed, limit rod 47 is pulled out to release the lock between connecting block 44 and U-shaped channel plate 45. At the same time, insertion rod 421 is pulled out from insertion hole 422 to release the fixation of moving seat 41.

[0041] At this time, the hydraulic cylinder 43 retracts. Due to the enormous weight of the slide plate 1 and the shield machine body 2, their inertia keeps them stationary. The retraction force acts in the opposite direction on the moving seat 41, pulling the moving seat 41 forward along the guide rail 31 until the hydraulic cylinder 43 is fully retracted. After the moving seat 41 returns to its original position, the insertion rod 421 is inserted again to fix it in the next insertion hole 422, and the connecting block 44 and the U-shaped groove plate 45 are relocked. By repeating the above action of extending the hydraulic cylinder 43, the stepping translation of the shield machine can be realized.

[0042] When it is necessary to extend the moving distance, the rear guide rail 31 of the area already moved by the sliding plate 1 can be disassembled. Specifically, the L-shaped plate 35 is slid out of the L-shaped groove 34, and the ground insertion rod 33 is pulled out. Then, the section of guide rail 31 is moved to the front end in the forward direction for splicing and installation, thereby achieving unlimited extension of the track. Through this synergistic action of the pushing mechanism 4 and the disassembly mechanism 3, this utility model solves the problems of complex translation structure, low precision, and poor adaptability of the existing shield machine in the prior art.
