Description

Technical Field

[0001] This utility model relates to the field of tunnel equipment technology, specifically to an integrated tunnel demolition trolley. Background Technology

[0002] In water conveyance tunnels, the dismantling of steel structural components (located between tracks), ventilation ducts (located on the tunnel side), hoisted ventilation and water pipes (located on the tunnel side), high-voltage cables (located at the bottom and / or top of the tunnel), and other small parts is necessary. Dismantling is generally carried out using a demolition trolley that moves along tracks at the bottom of the tunnel. Existing tunnel demolition trolleys typically consist of a moving frame that moves along tracks and a crane mounted on the moving frame. The crane lifts and transports the dismantled structure out or transfers it to other transport equipment (such as transport trolleys). However, existing tunnel demolition trolleys have the following shortcomings:

[0003] 1) The crane is either located above or in the middle of the mobile frame, or at the front or rear of the mobile frame, which cannot meet the requirements for dismantling the ventilation ducts and hoisting water pipes on the side of the tunnel.

[0004] 2) The overall structural layout is unreasonable, making it difficult to simultaneously meet the dismantling requirements of steel structural components between tracks, tunnel side pipes and high-voltage cables, tunnel top pipes and high-voltage cables, and other small components. It has poor adaptability and is not conducive to improving work efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated tunnel demolition trolley with a reasonable overall layout, which can meet the dismantling requirements of pipelines, cables and other components at various locations in the tunnel, has strong adaptability and helps to improve work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An integrated tunnel demolition trolley includes a movable frame and wheels located at the bottom of both sides of the movable frame. The movable frame forms a portal-shaped space between the two wheels. A first lifting mechanism is provided at the top of the portal-shaped space. A first load-bearing platform is provided on both sides of the portal-shaped space, a second load-bearing platform is provided above the portal-shaped space, and a cantilever that can extend to one side of the movable frame is slidably provided above the second load-bearing platform. A second lifting mechanism is provided at the cantilever end, and a third load-bearing platform is provided at the top of the movable frame.

[0008] As a further improvement to the above technical solution:

[0009] The second lifting mechanism is movable on the cantilever.

[0010] The cantilever is provided with a guide groove extending along its length, and the second lifting mechanism is slidably mounted on the guide groove.

[0011] The second lifting mechanism includes a sliding seat and a lifting hoist. Both sides of the cantilever have guide grooves, and both sides of the top of the sliding seat are provided with pulleys. The pulleys on both sides of the sliding seat slide in the guide grooves on both sides of the cantilever, and the lifting hoist is mounted on the sliding seat.

[0012] Both the lifting crane and the first lifting mechanism are electric hoists.

[0013] The second load-bearing platform is equipped with cable winding columns.

[0014] The second load-bearing platform is provided with multiple support columns, and the third load-bearing platform is located on top of each support column.

[0015] Ladders are provided under the first, second, and third load-bearing platforms.

[0016] The first, second, and third load-bearing platforms are all equipped with railings on their outer sides.

[0017] The second support platform extends out to one side of the moving frame, and the first support platform extends out to the other side of the moving frame.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This utility model relates to an integrated tunnel demolition trolley. In use, the trolley is placed on a track at the bottom of the tunnel. The trolley moves along the track to dismantle relevant components within the tunnel. The specific dismantling process is as follows: a portal-shaped space allows a transport trolley to enter. A first lifting mechanism at the top of the portal space hoists the dismantled steel structural components between the tracks onto the transport trolley, which then transports them out. A cantilever extends a second lifting mechanism to the side of the tunnel, hoisting pipes, cables, and other components dismantled from the tunnel side onto the corresponding first support platform. Pipes and other components at the top of the tunnel can be directly dismantled onto a third support platform by operators standing on it. This integrated tunnel demolition trolley has two main advantages. First, it can use a second lifting mechanism mounted on the cantilever to hoist pipes and other components to be demolished from the tunnel side to the first load-bearing platform on the corresponding side, thus meeting the requirements for demolishing pipes and other components from the tunnel side. Second, its overall layout is reasonable and can simultaneously meet the requirements for demolishing steel structural components between tracks, pipes and cables from the tunnel side, pipes and cables from the tunnel top, and other components. It is highly adaptable and helps to improve work efficiency. Attached Figure Description

[0028] Figure 1 and Figure 2This invention illustrates an embodiment of the integral tunnel demolition trolley of the present invention. The integral tunnel demolition trolley of this embodiment includes a movable frame 1 and traveling wheels 2 located at the bottom of both sides of the movable frame 1. The movable frame 1 forms a portal space 3 between the traveling wheels 2 on both sides. A first lifting mechanism 4 is provided at the top of the portal space 3. A first load-bearing platform 5 is provided on both sides of the movable frame 1 outside the portal space 3. A second load-bearing platform 6 is provided above the portal space 3. A cantilever 7 that can extend to one side of the movable frame 1 is slidably provided above the second load-bearing platform 6. A second lifting mechanism 8 is provided at the cantilever end of the cantilever 7. A third load-bearing platform 9 is provided at the top of the movable frame 1.

[0029] In use, the integrated tunnel demolition trolley is placed on the track at the bottom of the tunnel. The trolley moves along the track to dismantle the relevant components inside the tunnel. The specific dismantling process is as follows: the portal space 3 allows the transport trolley to enter. The first lifting mechanism 4 at the top of the portal space 3 is used to lift the dismantled steel structural components between the tracks to the transport trolley, which then transports them out. The cantilever 7 can extend the second lifting mechanism 8 to the side of the tunnel to lift the pipes, cables and other components dismantled on the side of the tunnel to the first load-bearing platform 5 on the corresponding side. The pipes and other components at the top of the tunnel can be directly dismantled onto the third load-bearing platform 9 by the operator standing on the third load-bearing platform 9. This integrated tunnel demolition trolley has two main advantages: First, it can use the second lifting mechanism 8 mounted on the cantilever 7 to lift pipes and other components to be demolished on the side of the tunnel to the first load-bearing platform 5 on the corresponding side, thus meeting the requirements for demolishing pipes and other components on the side of the tunnel. Second, its overall layout is reasonable and can simultaneously meet the requirements for demolishing steel structural components between tracks, pipes and cables on the side of the tunnel, pipes and cables on the top of the tunnel, and other components. It is highly adaptable and helps to improve work efficiency.

[0030] Furthermore, in this embodiment, the second lifting mechanism 8 is movably mounted on the cantilever 7, facilitating the insertion and extension of the movable frame 1.

[0031] Furthermore, in this embodiment, the cantilever 7 is provided with a guide groove 71 extending along its length, and the second lifting mechanism 8 is slidably disposed on the guide groove 71. The second lifting mechanism 8 is slidably disposed on the guide groove 71, which can move the lifted component along the guide groove 71 to the second support platform 6.

[0032] Furthermore, in this embodiment, the second lifting mechanism 8 includes a sliding seat 81 and a lifting hoist 82. Both sides of the cantilever 7 have guide grooves 71, and both sides of the top of the sliding seat 81 are provided with pulleys 83. The pulleys 83 on both sides of the sliding seat 81 slide smoothly in the guide grooves 71 on both sides of the cantilever 7. The lifting hoist 82 is mounted on the sliding seat 81. The sliding seat 81 slides smoothly in the guide grooves 71 via the pulleys 83, allowing for stable and smooth movement.

[0033] Furthermore, in this embodiment, both the lifting hoist 82 and the first lifting mechanism 4 are electric hoists. Of course, other mechanisms with lifting and hoisting functions can also be used.

[0034] Furthermore, in this embodiment, the second support platform 6 is provided with cable winding posts 61. After the cable is removed, it is hoisted to the second support platform 6 by the second lifting mechanism 8, and the operator on the second support platform 6 winds the cable around the cable winding posts 61. Multiple cable winding posts 61 can be provided on the second support platform 6, and they are arranged at intervals along the length and width directions of the second support platform 6.

[0035] Furthermore, in this embodiment, a guide rail is provided below the third support platform 9, and a hanging wheel is provided on the cantilever 7, with the hanging wheel slidably suspended on the guide rail.

[0036] Furthermore, in this embodiment, the second support platform 6 is provided with multiple support columns 62, and the third support platform 9 is located on top of each support column 62. Preferably, the support columns 62 can be telescopic columns, which facilitates the adjustment of the height of the third support platform 9 to meet the dismantling requirements of operators of different heights for the components at the top of the tunnel.

[0037] Furthermore, in this embodiment, ladders 10 are provided below the first support platform 5, the second support platform 6, and the third support platform 9 to facilitate operators to go up and down the first support platform 5, the second support platform 6, and the third support platform 9.

[0038] Furthermore, in this embodiment, the outer sides of the first support platform 5, the second support platform 6, and the third support platform 9 are all equipped with railings 11 to improve safety.

[0039] Furthermore, in this embodiment, the second support platform 6 extends out to one side of the moving frame 1, allowing it to be closer to the tunnel sidewall, which is more conducive to the dismantling of the tunnel side components. Of course, at this time, a hoisting opening for the second lifting mechanism 8 to pass through can also be opened in the extended part of the second support platform 6 to avoid obstructing the hoisting operation of the second lifting mechanism 8. The first support platform 5 extends out to the other side of the moving frame 1, which on the one hand facilitates the dismantling of the components on the other side of the tunnel by the operators, and on the other hand, facilitates the installation of a ladder 10 above the extended part for climbing up and down the second support platform 6, making it convenient to climb up and down the second support platform 6.

[0040] 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.
