Description

Technical Field

[0001] This utility model belongs to the field of tunnel shield technology, and in particular relates to a rapid horizontal movement construction device for a shield machine rear-mounted trolley inside the tunnel. Background Technology

[0002] With urban development, the utilization rate of urban underground space is gradually increasing, and urban transportation, pipelines and utility tunnels are increasingly being developed underground. Shield tunneling is a fully mechanized construction method in the underground excavation method. Due to its characteristics such as not affecting ground traffic and facilities, applicability to various strata, construction safety, and fast tunneling speed, it is being used more and more widely. It often has technical and economic advantages in the construction of tunnels with large burial depths and long sections.

[0003] As a fully mechanized construction method, the tunnel boring machine (TBM) is the main construction machinery in shield tunneling. Its total length typically ranges from 100m to 200m (depending on the design, such as the excavation diameter). The TBM mainly consists of the main shield machine and several (usually 5-7 sections) of supporting trolleys, connected by pins. After the tunnel is completed, the main shield machine and the supporting trolleys are disassembled and lifted to the surface sequentially in the receiving shaft, and then transported away by flatbed trucks. The main shield machine can be disassembled and lifted out in sections or even blocks, while the supporting trolleys often need to be lifted out as a whole in sections, each typically 10-15m in length.

[0004] As a high-cost, high-efficiency mode of transportation, urban subways are typically built in densely populated areas to increase passenger flow and reduce debt repayment pressure. Subway stations are often located on major traffic arteries with high pedestrian traffic. To minimize the impact on surface traffic, cut-and-cover or top-and-bottom construction methods are usually chosen when conditions permit. However, surface conditions often do not allow for hoisting shafts, or only allow for small ones, which cannot meet the hoisting requirements of the auxiliary trolleys. This necessitates the horizontal transport of the auxiliary trolleys within the tunnel to a larger hoisting shaft at a nearby station before they are hoisted to the surface. Furthermore, to save on temporary construction site and facility costs, temporary facilities such as tunnel boring machine (TBM) excavation pits, circulating water tanks, dormitories, and canteens are usually located within the same station. In the construction of double-track tunnels within the same section, after one tunnel is completed, the TBM and auxiliary trolleys need to be moved back to the starting station for reassembly and testing before starting construction on the other tunnel or an adjacent section. To save on the hoisting and relocation costs of the TBM equipment, the auxiliary trolleys are also usually returned to the starting station via horizontal transport within the tunnel.

[0005] However, in existing technologies, the transport of the rear-mounted trolley involves first welding steel pipes between two separate platforms at the bottom of the trolley to prevent them from opening during lifting, transport, and hoisting. Then, jacks are used to lift the trolley, and H-beams are placed between the lifted trolley and the transport vehicle for connection and fixation. This process requires frequent welding of steel pipes and repeated placement of jacks, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0006] In view of this, the present invention provides a rapid translational construction device for a shield tunneling machine's rear-mounted trolley inside the tunnel, to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rapid horizontal movement construction device for a rear-mounted trolley within a tunnel boring machine (TBM) includes: a battery-powered vehicle trolley, hopper chassis, support plates, a bottom fixing device for the rear-mounted trolley, a lifting device, H-beams, and a hydraulic pump. Multiple hopper chassis are sequentially hinged to the rear end of the battery-powered vehicle trolley. Each hopper chassis is equipped with a support plate, and each support plate is equipped with the bottom fixing device and the lifting device for the rear-mounted trolley. Multiple H-beams are mounted on the hopper chassis, and a hydraulic pump is installed in each hopper chassis. The lifting device is connected to the hydraulic pump pipeline; the bottom fixing device of the rear supporting trolley includes a first lifting cylinder, a crossbar, a rod support and a fixed bracket. The first lifting cylinder is fixedly installed on the upper surface of the support plate, the rod support is fixedly installed on the output end of the first lifting cylinder, the crossbar is installed in the rod support, and a pair of fixed brackets are respectively installed at both ends of the crossbar. The two separate platforms at the bottom of the rear supporting trolley are respectively inserted into the fixed brackets, and the first lifting cylinder is connected to the hydraulic pump pipeline.

[0009] Furthermore, the bottom fixing device of the rear trolley also includes two first telescopic hydraulic cylinders, which are respectively installed between the ends of the crossbar and the fixed bracket, and the first telescopic hydraulic cylinders are connected to the hydraulic pump pipeline.

[0010] Furthermore, the lifting device includes a support rod, a second telescopic cylinder, and a bidirectional cylinder. Support frames are provided at both ends of the support plate, and the support rod is movably connected in the support frames. A pair of second telescopic cylinders are respectively fixedly connected to both ends of the support rod, and a pair of bidirectional cylinders are respectively installed at the output ends of the two second telescopic cylinders. Both the second telescopic cylinders and the bidirectional cylinders are connected to the hydraulic pump pipeline.

[0011] Furthermore, the lifting device also includes multiple pads, which are respectively installed at the two output ends of the bidirectional hydraulic cylinder.

[0012] Furthermore, the support frame is provided with a guide groove for guiding the support rod to slide in the vertical direction.

[0013] Furthermore, the support plate is provided with insertion slots at both ends, and the side of the slag hopper chassis is inserted into the insertion slots.

[0014] Furthermore, the H-beam is horizontally installed on the support parts at the front and rear ends of the slag hopper chassis.

[0015] The beneficial effects of this utility model are as follows:

[0016] The first telescopic cylinders at both ends of the crossbar of this utility model extend to move the fixed bracket to the bottom of the two separate platforms of the rear trolley. The first lifting cylinder lifts the crossbar so that the two separate platforms of the bottom of the rear trolley are inserted into the fixed bracket. The fixed brackets at both ends do not support the crossbar. The purpose is to fix it laterally and prevent it from opening during lifting, transportation and hoisting, thus avoiding the need for welding steel pipes.

[0017] The second telescopic cylinder extends, moving the two-way cylinders at both ends of the support rod between the track and the rear trolley. Then, the top and bottom ends of the two-way cylinders extend, lifting the rear trolley. During this process, the U-shaped guide groove of the support frame guides the vertical movement of the support rod, making the movement of the support rod more stable. Then, the H-beam is placed on the support part of the rear trolley and the slag hopper chassis. The two-way cylinder retracts, and the rear trolley falls on the H-beam, which is then threadedly fixed to the support part and the bottom end of the rear trolley. This avoids the need to frequently place multiple jacks, improving work efficiency.

[0018] The support plate is directly inserted into the side of the slag hopper chassis via a slot, making installation quick and without damaging the chassis. Attached Figure Description

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.

[0029] See attached document Figure 1-6As shown, this utility model provides a rapid horizontal movement construction device for the rear-mounted trolley of a tunnel boring machine, comprising: a battery-powered vehicle trolley 10, a slag hopper chassis 20, a support plate 30, a bottom fixing device 40 for the rear-mounted trolley, a lifting device 50, H-beams 60, and a hydraulic pump 70. Multiple slag hopper chassis 20 are sequentially hinged to the rear end of the battery-powered vehicle trolley 10. Each slag hopper chassis 20 is equipped with a support plate 30, and each support plate 30 is equipped with the bottom fixing device 40 and the lifting device 50. After the rear-mounted trolley is lifted, multiple H-beams 60 are installed on the slag hopper chassis 20. The rear-mounted trolley rests on the multiple H-beams 60 before being moved further. The slag hopper chassis 20 is connected to the H-beam 60 by bolts. A hydraulic pump 70 is installed in each slag hopper chassis 20. The lifting device 50 is connected to the hydraulic pump 70 by pipeline. The bottom fixing device 40 of the rear supporting trolley includes a first lifting cylinder 41, a crossbar 42, a rod support 43 and a fixed bracket 44. The first lifting cylinder 41 is fixedly installed on the upper surface of the support plate 30. The rod support 43 is fixedly installed on the output end of the first lifting cylinder 41. The crossbar 42 is installed in the rod support 43. A pair of fixed brackets 44 are respectively installed at both ends of the crossbar 42. The two separate platforms at the bottom of the rear supporting trolley are respectively inserted into the fixed brackets 44. The first lifting cylinder 41 is connected to the hydraulic pump 70 by pipeline.

[0030] In a preferred embodiment, the bottom fixing device 40 of the rear supporting trolley further includes two first telescopic cylinders 45. The two first telescopic cylinders 45 are respectively installed between the ends of the crossbar 42 and the fixed bracket 44, and the first telescopic cylinders 45 are connected to the hydraulic pump 70 via pipelines. By extending the first telescopic cylinders 45, the fixed bracket 44 can be moved to move under the two separate platforms at the bottom of the rear supporting trolley, which can accommodate the two separate platforms at the bottom of the rear supporting trolley with different widths.

[0031] The first telescopic cylinders 45 at both ends of the crossbar 42 extend, moving the fixed bracket 44 to the bottom of the two separate platforms of the rear trolley. The first lifting cylinder 41 lifts the crossbar 42, so that the two separate platforms at the bottom of the rear trolley are inserted into the fixed bracket 44 respectively. The fixed brackets 44 at both ends do not provide support, but are used for lateral fixation to prevent them from opening during lifting, transportation and hoisting, and to avoid welding steel pipes.

[0032] In a preferred embodiment, the lifting device 50 includes a support rod 51, a second telescopic cylinder 52, and a double-acting cylinder 53. Support frames 31 are provided at both ends of the support plate 30. The support rod 51 is movably connected in the support frame 31. A pair of second telescopic cylinders 52 are respectively fixedly connected to both ends of the support rod 51. A pair of double-acting cylinders 53 are respectively installed at the output ends of the two second telescopic cylinders 52. Both the second telescopic cylinders 52 and the double-acting cylinders 53 are connected to the hydraulic pump 70 pipeline.

[0033] In a preferred embodiment, the lifting device 50 further includes multiple pads 54, which are respectively installed at the two output ends of the bidirectional hydraulic cylinder 53. The pads 54 can increase the support area for the rear supporting trolley, making the lifting process of the rear supporting trolley more stable.

[0034] In a preferred embodiment, the support frame 31 is provided with a guide groove 311 for guiding the support rod 51 to slide in the vertical direction. The U-shaped guide groove of the support frame 31 guides the vertical movement of the support rod 51, making the movement of the support rod 51 more stable.

[0035] In a preferred embodiment, the support plate 30 is provided with insertion slots 32 at both ends, and the sidewall 21 of the slag hopper chassis 20 is inserted into the insertion slots 32. The support plate 30 is directly inserted into the sidewall 21 of the slag hopper chassis 20 through the insertion slots 32, which is quick to install and does not damage the slag hopper chassis 20.

[0036] In a preferred embodiment, the support portion 22 is located directly above the wheel of the slag hopper chassis 20, and H-beams 60 are laterally installed on the support portions 22 at the front and rear ends of the slag hopper chassis 20, which provides better load-bearing capacity.

[0037] Working principle: The first telescopic cylinders 45 at both ends of the crossbar 42 extend, moving the fixed brackets 44 to below the two separate platforms at the bottom of the rear trolley. The first lifting cylinder 41 then lifts the crossbar 42, causing the two separate platforms at the bottom of the rear trolley to be inserted into the fixed brackets 44 respectively. The fixed brackets 44 at both ends do not provide support; their purpose is to provide lateral fixation and prevent them from opening during lifting, transportation, and hoisting, thus avoiding the need for welding steel pipes. The second telescopic cylinder 52 extends, moving the bidirectional cylinders 53 at both ends of the support rod 51 between the track and the rear trolley. Then, the bidirectional cylinders 52 extend... 3. The top and bottom ends extend, lifting the rear trolley. The support rod 51, the second telescopic cylinder 52, and the bidirectional cylinder 53 also move vertically upward. During this process, the U-shaped guide groove of the support frame 31 guides the vertical movement of the support rod 51, making the movement of the support rod 51 more stable. Then, the H-beam 60 is placed on the support part 22 of the rear trolley and the slag hopper chassis 20. The bidirectional cylinder 53 retracts, and the rear trolley falls on the H-beam 60. The H-beam 60 is then threadedly fixed to the support part 22 and the bottom end of the rear trolley. This avoids the need to frequently place multiple jacks and improves work efficiency.
