Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a continuous operation lining trolley for extremely thick planar arch tops. Background Technology

[0002] Bridges and tunnels are widely used in the construction of railways and highways. However, in many complex terrain conditions, the construction often results in surrounding rock deformation and collapse accidents. Therefore, in order to ensure the safety of personnel and equipment in tunnel construction, it is necessary to use a secondary lining trolley for lining. During the operation, a waterproof board is first hung on the concrete wall of the tunnel. Then, the secondary lining trolley is constructed to the end of the invert arch, and then the secondary lining is carried out.

[0003] The formwork of existing secondary lining trolleys is usually made of steel plates. However, the surface of steel plates is rough, which affects the smoothness of the concrete component surface, making manual demolding difficult and resulting in low demolding efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous operation lining trolley for extremely thick planar arch tops, which aims to solve the problems of existing lining trolley templates being unfavorable for manual demolding and having low demolding efficiency.

[0005] To achieve the above objectives, this utility model provides a continuous operation lining trolley for extremely thick planar arches, comprising a first trolley, a second trolley, a third trolley, a first template, a first lifting mechanism, a first lateral cylinder, a first auxiliary rod, a first side mold, a third template, a third lifting mechanism, a third lateral cylinder, a third auxiliary rod, and a third side mold; the second trolley is disposed between the first trolley and the third trolley; the first template is assembled on the top of the first trolley; the first lifting mechanism is assembled on the bottom of the first trolley; the first side mold is rotatably disposed on one side of the first template; the first lateral cylinder is assembled between the first trolley and the first side mold; the first auxiliary rod is assembled between the first trolley and the first side mold; the third template is assembled on the top of the third trolley; the third lifting mechanism is assembled on the bottom of the third trolley; the third side mold is rotatably disposed on one side of the third template; the third lateral cylinder is assembled between the third trolley and the third side mold; and the third auxiliary rod is assembled between the third trolley and the third side mold.

[0006] The first lifting mechanism is the same as the third lifting mechanism. The first lifting mechanism includes a first lifting cylinder and a first base block. The first lifting cylinder is fixedly connected to the first trolley and is located at the bottom of the first trolley. The first base block is fixedly connected to the first lifting cylinder and is located on the side of the first lifting cylinder away from the first trolley.

[0007] The first vehicle includes a first support and a first walking mechanism. The first support is fixedly connected to the first template and is located at the bottom of the first template. The first walking mechanism is assembled at the bottom of the first support.

[0009] The third vehicle includes a third support and a third traveling mechanism. The third support is fixedly connected to the third template and is located at the bottom of the third template. The third traveling mechanism is assembled at the bottom of the third support.

[0010] The third vehicle also includes a reinforcing rib, which is fixedly connected to the third bracket and located on one side of the third bracket.

[0012] This utility model discloses a continuous operation trolley for ultra-thick planar arch secondary lining. The first trolley provides support and installation conditions for the first template, the first lifting mechanism, the first lateral cylinder, and the first auxiliary rod. The third trolley provides installation conditions for the third template, the third lifting mechanism, the third lateral cylinder, and the third auxiliary rod. The first trolley supports the secondary lining casting through the first template and the first side mold. The third trolley also supports the secondary lining casting through the third template and the third side mold. When the secondary lining is cast and demolded, the first lateral cylinder actuates to pull the first side mold, causing the first side mold to rotate and fold inward on the first template. At this time, the first lifting mechanism actuates again, lowering the trolley. The first trolley pulls the first template, thus demolding the first template and the first side plate. Similarly, the third side mold and the third template are demolded by the third lateral hydraulic cylinder and the third lifting mechanism. Conversely, by operating in the reverse direction to build the support surface for casting, the second trolley can also be raised and lowered for demolding. The first auxiliary rod and the third auxiliary rod rotate together when the first side mold and the third side mold rotate, assisting the rotation of the first side mold and the third side mold. The entire demolding process is controlled by hydraulic cylinders and lifting mechanisms. Compared with traditional manual demolding, the demolding operation is simple, fast, and efficient, thus solving the problem that the existing secondary lining trolley template is not conducive to manual demolding and has low demolding efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1 to 2 This utility model provides a continuous operation lining trolley for extremely thick planar arch tops, comprising a first trolley, a second trolley, a third trolley, a first template 1, a first lifting mechanism 2, a first lateral cylinder 3, a first auxiliary rod 4, a first side mold 5, a third template 6, a third lifting mechanism 7, a third lateral cylinder 8, a third auxiliary rod 9, and a third side mold 10; the second trolley is positioned between the first trolley and the third trolley, the first template 1 is mounted on the top of the first trolley, the first lifting mechanism 2 is mounted on the bottom of the first trolley, and the first side mold 5 is rotatably mounted. On one side of the first template 1, the first lateral hydraulic cylinder 3 is assembled between the first trolley and the first side mold 5, the first auxiliary rod 4 is assembled between the first trolley and the first side mold 5, the third template 6 is assembled on the top of the third trolley, the third lifting mechanism 7 is assembled on the bottom of the third trolley, the third side mold 10 is rotatably disposed on one side of the third template 6, the third lateral hydraulic cylinder 8 is assembled between the third trolley and the third side mold 10, and the third auxiliary rod 9 is assembled between the third trolley and the third side mold 10.

[0021] In this embodiment of the invention, the first trolley provides support and installation conditions for the first template 1, the first lifting mechanism 2, the first lateral cylinder 3, and the first auxiliary rod 4. The third trolley provides installation conditions for the third template 6, the third lifting mechanism 7, the third lateral cylinder 8, and the third auxiliary rod 9. The first trolley supports the secondary lining casting through the first template 1 and the first side mold 5, and the third trolley supports the secondary lining casting through the third template 6 and the third side mold 10. When the secondary lining is cast and demolded, the first lateral cylinder 3 pulls the first side mold 5, causing the first side mold 5 to rotate and fold inward on the first template 1. At this time, the first lifting mechanism 2 then operates, lowering the first trolley and pulling the first template 1, thus achieving demolding of the first template 1 and the first side mold 5. Similarly, the third side mold 10 and the third template 6 are demolded through the action of the third lateral cylinder 8 and the third lifting mechanism 7. Conversely, by reversing the above process, a support surface for casting can be built, and the second trolley can also achieve lifting and demolding. The first auxiliary rod 4 and the third auxiliary rod 9 rotate together when the first side mold 5 and the third side mold 10 rotate, assisting the first side mold 5 and the third side mold 10 in rotating. The entire demolding process is controlled by hydraulic cylinders and lifting mechanisms. Compared with traditional manual demolding, the demolding operation is simple, quick, and efficient, thus solving the problems of existing secondary lining trolley templates being unsuitable for manual demolding and having low demolding efficiency.

The first lifting cylinder 11 is fixedly connected to the first trolley and is located at the bottom of the first trolley. The first base block 12 is fixedly connected to the first lifting cylinder 11 and is located on the side of the first lifting cylinder 11 away from the first trolley.

[0023] In this embodiment of the utility model, the first base block 12 provides support for the first lifting cylinder 11. When the first lifting cylinder 11 extends / contracts, it can lift / lower the first trolley, thereby lifting or pulling the first template 1 to realize the height adjustment and demolding action of the template.

[0024] Furthermore, the first vehicle includes a first support 13 and a first walking mechanism 14. The first support 13 is fixedly connected to the first template 1 and is located at the bottom of the first template 1. The first walking mechanism 14 is assembled at the bottom of the first support 13.

[0025] In this embodiment of the utility model, the first support 13 provides an installation site for the first walking mechanism 14, the first lateral hydraulic cylinder 3, and the first template 1. The first walking mechanism 14 can drive the first support 13 to move in the tunnel, which facilitates moving to the next secondary lining construction position and improves construction flexibility.

[0026] Furthermore, the first vehicle also includes a small cross brace 15, which is fixedly connected to the first bracket 13 and located on one side of the first bracket 13.

[0027] In this embodiment of the utility model, the small cross brace 15 can strengthen the structural strength of the first support 13, prevent the first lifting mechanism 2 from being damaged due to the large weight of the poured cement, and ensure construction safety and equipment stability.

[0028] Furthermore, the third vehicle includes a third support 16 and a third traveling mechanism 17. The third support 16 is fixedly connected to the third template 6 and is located at the bottom of the third template 6. The third traveling mechanism 17 is assembled at the bottom of the third support 16.

[0029] In this embodiment of the utility model, the third support 16 provides an installation site for the third traveling mechanism 17, the third lateral hydraulic cylinder 8, and the third template 6. The third traveling mechanism 17 can drive the third support 16 to move within the tunnel, facilitating the switching of construction positions and cooperating with the first vehicle to complete the secondary lining pouring operation.

[0030] Furthermore, the third vehicle also includes a reinforcing rib 18, which is fixedly connected to the third bracket 16 and located on one side of the third bracket 16.

[0031] In this embodiment of the utility model, the reinforcing rib 18 can enhance the structural strength of the third support 16, prevent the third lifting mechanism 7 from being damaged due to the large weight of the poured cement, and further ensure construction safety and equipment service life.

[0032] Furthermore, the second vehicle includes a second template 19, a connector 20, an upper column 21, a lower column 22, a second lifting cylinder 23, and a second traveling mechanism 24. The upper column 21 is slidably connected to the lower column 22 and is located at the top of the lower column 22. The connector 20 is fixedly connected to the upper column 21 and is located on the side of the upper column 21 away from the lower column 22. The second template 19 is fixedly connected to the connector 20 and is located on the side of the connector 20 away from the upper column 21.

The second traveling mechanism 24 is assembled at the bottom of the lower column 22.

[0033] In this embodiment of the invention, the second vehicle is positioned to guide the third and first vehicles, providing a reference for their entry into the tunnel construction position and ensuring installation accuracy. When the second lifting cylinder 23 extends, it pushes the upper column 21 upward within the lower column 22, lifting the connecting piece 20 and subsequently the second template 19. Conversely, when the second lifting cylinder 23 retracts, it pulls down the second template 19, achieving lifting and demolding of the second template 19. The second traveling mechanism 24 allows the second vehicle to move within the tunnel, facilitating its movement alongside the first and third vehicles to the next secondary lining construction position, enabling continuous construction.
