Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a TBM sleeper device. Background Technology

[0002] In TBM tunnel construction, the transportation of materials and the excavation of the TBM both require the use of steel tracks. The steel tracks are laid on sleepers, which support the TBM construction tracks and ensure the stability and flatness of the tracks.

[0003] Currently, tunnel sleeper laying relies entirely on manual labor. However, the existing sleepers are integral structures and quite heavy, which not only makes sleeper transportation in tunnels inconvenient but also consumes a lot of manpower during sleeper installation. This reduces construction efficiency and increases construction risks, failing to meet current construction requirements. Utility Model Content

[0004] The purpose of this invention is to provide a TBM sleeper device that is easy to transport and requires less manual installation, thereby improving construction efficiency.

[0005] The technical solution of this utility model is: a TBM sleeper device, comprising multiple longitudinally spaced carriers, each carrier having sleepers detachably connected to both its left and right ends; two spaced material transport tracks are detachably installed on the upper surfaces of the multiple carriers; and a trolley track is detachably installed on the upper surfaces of the multiple sleepers at each end.

[0006] Both the material transport track and the trolley track extend longitudinally.

[0007] In the above scheme, the existing integrated sleeper structure is designed as a split structure with a load-bearing body and detachable sleepers, which facilitates transportation, allows the TBM to follow and extend synchronously, and the manual installation after disassembly is more labor-saving, thereby improving construction efficiency.

[0008] Preferably, the upper surface of the carrier is provided with two first positioning mechanisms and two second positioning mechanisms. The two transverse ends of one material transport track are respectively limited by one first positioning mechanism and one second positioning mechanism, and the two transverse ends of the other material transport track are respectively limited by another first positioning mechanism and another second positioning mechanism.

[0009] Preferably, the first positioning mechanism is located on the inner side of the material transport track, and the second positioning mechanism is located on the outer side of the material transport track.

[0010] Preferably, the first positioning mechanism abuts against the material transport track, and the second positioning mechanism engages with the material transport track.

[0011] Preferably, the first positioning mechanism includes a mounting plate disposed on the upper surface of the carrier and an abutment block connected to one end of the mounting plate, the abutment block abutting against the material transport track.

[0012] Preferably, the second positioning mechanism includes a base disposed on the carrier and a locking block connected to one side of the base. A locking cavity is formed between the locking block and the carrier. One lower end of the material transport track extends into the locking cavity, and the lower surface of the locking block engages with the material transport track.

[0013] Preferably, the sleeper is provided with a connecting groove for installation with the load-bearing body.

[0014] Preferably, the upper surface of the sleeper is provided with a third positioning mechanism, which abuts against the trolley track.

[0015] Preferably, the third positioning mechanism abuts against the inner side of the trolley track.

[0016] Preferably, both the carrier and the sleeper are hollow structures.

[0017] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0018] 1. The TBM sleeper device is designed as a split structure with a load-bearing body and a sleeper that can be detached and installed. This facilitates transportation, allows the TBM to follow and extend synchronously during tunneling, and the manual installation after disassembly is more labor-saving, thereby improving construction efficiency.

[0019] Second, the detachable structure of the sleeper, material transport track and trolley track of this utility model can be disassembled and installed in a cyclical manner following the stepping of the trolley, thereby reducing the material used in the entire process and making construction more convenient and reasonable.

[0020] Third, the TBM sleeper device is equipped with three positioning mechanisms to define each track, which enables rapid track installation and is more adaptable to the working environment inside the tunnel.

[0021] Fourth, the TBM sleeper device has a simple structure, is easy to assemble and disassemble, has high convenience, strong stability, and is more adaptable to long-distance TBM tunneling and transportation.

[0022] Fifth, the use of hollow structure for the load-bearing body and sleepers can reduce weight and facilitate manual handling and installation. Attached Figure Description

[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0028] like Figure 1 As shown, the TBM sleeper device provided in this embodiment includes a carrier 1, a material transport track 2, a trolley track 3, a sleeper 4, a first positioning mechanism 5, a second positioning mechanism 6, and a third positioning mechanism 7.

[0029] The carrier 1 has connection nodes at both ends. For example... Figure 3 As shown, the sleeper 4 is provided with a connecting groove 41 for installation with the carrier 1. The connecting node is assembled in the connecting groove 41 and can be fastened by detachable fasteners (such as bolts or others).

[0030] Multiple integrated load-bearing bodies 1 and sleepers 4 are arranged at intervals along the length of the tunnel. Each load-bearing body 1 is connected to two material transport tracks 2, which are spaced apart along the length of each load-bearing body 1. Figure 1 , Figure 2 As shown, each of the shown carriers 1 has two first positioning mechanisms 5 and two second positioning mechanisms 6 on its upper surface. The material transport track 2 is an I-beam. The first positioning mechanisms 5 are located on the inner side of the material transport track 2, and the second positioning mechanisms 6 are located on the outer side of the material transport track 2.

[0031] The first positioning mechanism 5 includes a mounting plate 51 disposed on the upper surface of the carrier 1 and an abutment block 52 connected to one end of the mounting plate 51. The abutment block 52 abuts against the inner surface of the lower flange plate of the material transport track 2.

[0032] The second positioning mechanism 6 includes a base 61 disposed on the carrier 1 and a locking block 62 connected to one side of the base 61. A locking cavity 63 is formed between the locking block 62 and the carrier 1. The end of the lower flange of the material transport track 2 extends into the locking cavity 63, and the lower surface of the locking block 62 abuts against the upper surface of the lower flange.

[0033] like Figure 1 , Figure 3 As shown, a third positioning mechanism 7 is provided on the upper surface of the sleeper 4. The third positioning mechanism 7 abuts against the inner surface of the lower flange plate of the trolley track 3.

[0034] The aforementioned inner surface refers to the side surface that faces towards the center of the carrier 1, while the opposite side refers to the outer surface.

[0035] In use, first place the carrier 1 at the bottom of the tunnel and fix it in place. Then, insert the connecting groove 41 on the sleeper 4 into the end connecting node of the carrier 1. Next, install the material transport rails 2 one-to-one between the first positioning mechanism 5 and the second positioning mechanism 6. Finally, install the trolley rail 3. When installing the material transport rail 2, one end of its lower flange plate can be inserted into the clamping cavity 63 first, and then the other end of the lower flange plate can be pressed down to the side of the abutment block 52 and clamped. Alternatively, a transverse through groove can be set on the base 61. When installing the material transport rail 2, first slide the clamping block 62 out of the groove and remove it. Then, place the lower flange plate of the material transport rail 2 between the base 61 and the first positioning mechanism 5, and make the side of the lower flange plate contact the abutment block 52. Finally, insert the clamping block 62 into the groove. The installed clamping block 62 abuts against the upper surface of the lower flange plate.

[0036] During the TBM's movement, the sleepers 4, material transport rails 2, and trolley rails 3 can be disassembled and assembled simultaneously, achieving a dynamic cycle of disassembly and assembly. Furthermore, the disassembled load-bearing body 1 and sleepers 4 are easy to transport, saving a significant amount of manpower.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
