Description

Technical Field

[0001] This utility model relates to the field of tunnel operations, and in particular to a tunnel face operation trolley. Background Technology

[0002] Tunnels are an important form of engineering for human use of underground space. They are engineering structures buried in the strata of the earth. According to their purpose, they can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels; according to their length, they can be divided into short tunnels, medium tunnels, long tunnels, and extra-long tunnels; according to their cross-sectional area, they can be divided into tunnels with extremely small cross-sections, small cross-sections, medium cross-sections, large cross-sections, and extra-large cross-sections; according to their location, they can be divided into mountain tunnels, underwater tunnels, and urban tunnels; according to their geological conditions, they can be divided into soil tunnels and rock tunnels; and according to their burial depth, they can be divided into shallow tunnels and deep tunnels.

[0003] The tunnel face is the working face that continuously advances during the excavation of tunnels or underground projects. It is the "front line" of construction, not only the work area for rock and soil excavation but also a critical interface for controlling the stability of the surrounding rock and ensuring construction safety. The stability of the tunnel face directly affects the overall safety of the tunnel, and its instability may lead to accidents such as collapse and water inrush.

[0004] The tunnel face is the working face that continuously advances during tunnel excavation and is the core area of ​​tunnel construction. Therefore, a work platform is needed to operate on the tunnel face. In the authorized Chinese utility model patent "Announcement No.: CN211851896U, Title: Tunnel Face Work Platform with Dust Reduction Function", the work platform increases the working area of ​​the workers by setting up multiple working plates. The working plates are made of steel plates and are arranged in four layers from top to bottom, with the area of ​​the working plates increasing from top to bottom. The upper and lower working plates are fixed by connecting rods. Although the above application uses multiple working plates to increase the working area of ​​the workers, these multiple working plates are all fixed. During operation, the working plates are difficult to extend out. When not in operation, the working plates extend out, making it difficult for the work platform to pass through in relatively narrow places, which affects the progress of tunnel operation. Utility Model Content

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] This utility model provides a tunnel face working trolley, including a trolley frame.

[0008] Two walking systems are installed at the bottom of the trolley frame, and the walking systems are used to support the movement of the trolley frame.

[0010] The fixed platform is rotatably connected to the side of the trolley frame via a rotating assembly. The bottom of the fixed platform and the side of the trolley frame are connected via an angle control assembly, which is used to control the angle between the fixed platform and the moving platform assembly.

[0011] In this technical solution, the lateral position of the moving platform assembly can be controlled by the length control component, which allows the moving platform assembly to extend, thereby expanding the working area of ​​the work trolley. The angle control component can adjust the angle between the fixed platform and the moving platform assembly, allowing them to be folded up and unfolded. This makes the width of the work trolley adjustable, enabling it to pass through narrow tunnel sections more easily, improving the flexibility of the work trolley during operation, facilitating its use, and also facilitating tunnel face operations.

[0023] Preferably, a follower strip is connected to the side of the reinforcing column away from the fixed platform, and the end of the follower strip away from the reinforcing column is connected to one side of the execution plate.

[0024] In this technical solution, the movement trajectory of structures such as the execution plate can be further limited by using reinforcing columns and follower bars, while also increasing the stability of structures such as the moving stage assembly.

[0025] Preferably, the angle control component includes a mounting plate connected to the side of the trolley frame, an angle control telescopic device connected to one side of the mounting plate, and a rotating block connected to one end of the angle control telescopic device;

[0034] The positive and progressive effects of this utility model are as follows:

[0035] This invention utilizes a length control component to control the lateral position of the moving platform assembly, allowing the moving platform assembly to extend and thus expanding the working area of ​​the work trolley. An angle control component adjusts the angle between the fixed platform and the moving platform assembly, enabling them to be folded up and unfolded.

[0053] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0054] Figures 1 to 8 The diagram shown is a structural schematic of an embodiment of the tunnel face working trolley of this utility model. The tunnel face working trolley includes a trolley frame 1.

[0055] Two walking systems 2 are respectively installed at the bottom of the trolley frame 1, and the walking systems 2 are used to support the walking and moving of the trolley frame 1;

[0056] The work unit includes a fixed platform 3 and a movable platform assembly 4. The movable platform assembly 4 is disposed above the fixed platform 3, and the fixed platform 3 and the movable platform assembly 4 are slidably connected by a length control component 5, which is used to control the position of the movable platform assembly 4.

[0057] The fixed platform 3 is rotatably connected to the side of the trolley frame 1 via a rotating assembly 7. The bottom of the fixed platform 3 and the side of the trolley frame 1 are connected via an angle control assembly 6, which is used to control the angle between the fixed platform 3 and the moving platform assembly 4.

[0058] In this technical solution, the length control component 5 can control the lateral position of the moving platform component 4, thereby extending the moving platform component 4 and expanding the working area of ​​the work trolley. The angle control component 6 can adjust the angle between the fixed platform 3 and the moving platform component 4, thereby retracting and unfolding the fixed platform 3 and the moving platform component 4. This allows the width of the work trolley to be adjusted, making it easier for the work trolley to pass through narrow sections of the tunnel, improving the flexibility of the work trolley during operation, facilitating its use, and also facilitating tunnel face operations.

[0059] The walking system 2 consists of tracked wheels.

[0060] In this technical solution, the walking system 2 enables the work trolley to move stably within the tunnel.

[0061] When in use, the walking system 2 travels on the excavation foundation surface of the tunnel face, which is generally a sandy surface. Therefore, the walking system 2 can facilitate the movement of the work trolley on the sandy surface.

[0062] When in use, workers can stand on the trolley frame 1 and the fixed platform 3, and then the workers can carry out operations such as loading explosives at the tunnel face.

[0063] When the work trolley is not in use or needs to pass through relatively narrow positions, the fixed platform 3 and the moving platform assembly 4 can be retracted using the length control assembly 5 and the angle control assembly 6 to reduce the size of the work trolley, thereby facilitating the movement and storage of the work trolley and increasing its flexibility.

[0064] The mobile platform assembly 4 includes a mobile platform 41 and a protective fence 42. The mobile platform 41 is slidably disposed above the fixed platform 3, and the protective fence 42 is connected to the top of the mobile platform 41.

[0065] In this technical solution, the mobile station component 4 can be moved, thereby controlling the working area.

[0066] The length control component 5 includes an execution plate 51 and an adjustment plate 52. The execution plate 51 is connected to the bottom of the movable platform 41, and the adjustment plate 52 is connected to the bottom of the fixed platform 3.

[0067] A length-controlling telescopic device 53 is connected between the execution plate 51 and the adjustment plate 52.

[0068] In this technical solution, the lateral position of the moving stage assembly 4 can be controlled by the length control component 5.

[0069] The execution plate 51 is connected to a plurality of sliding rails 54 on the side near the fixed platform 3, and the surface of the sliding rails 54 is slidably connected through to one side of the fixed platform 3.

[0070] The end of the sliding track 54 away from the execution plate 51 is connected to the connecting plate 55, and the connecting plate 55 is slidably connected to the inner side of the fixed platform 3.

[0071] In this technical solution, the movement trajectory of the actuator plate 51 can be limited by the sliding rail 54 and the connecting plate 55.

[0072] The connecting plate 55 is connected to reinforcing columns 56 on both sides, and the surfaces of the reinforcing columns 56 are slidably connected to the two sides of the fixed platform 3.

[0073] The side of the reinforcing column 56 away from the fixed platform 3 is connected to a follower strip 57, and the side of the follower strip 57 away from the reinforcing column 56 is connected to one side of the execution plate 51.

[0074] In this technical solution, the reinforcing column 56 and the follower bar 57 can be used to further limit the movement trajectory of the actuator plate 51 and other structures, and at the same time increase the stability of the moving stage assembly 4 and other structures.

[0075] In use, the extension device 53 can be used to move the execution plate 51, which in turn can move the moving platform 41, thereby adjusting the lateral position of the moving platform 41 so that the operator can work on different positions of the working face.

[0076] When the moving platform 41 moves, it can drive the sliding rail 54 and the follower bar 57 to move in the same direction. When the follower bar 57 moves, it can drive the reinforcing column 56 to move in the same direction. When the sliding rail 54 and the reinforcing column 56 move, they can drive the connecting plate 55 to move in the same direction, thus limiting the movement trajectory of the moving platform 41 and increasing the stability of the moving platform 41.

[0077] The angle control component 6 includes a mounting plate 61, which is connected to the side of the trolley frame 1. An angle control telescopic device 62 is connected to one side of the mounting plate 61, and a rotating block 63 is connected to one end of the angle control telescopic device 62.

[0078] The rotating block 63 is rotatably connected to the surface of the fixed shaft 64. Both ends of the fixed shaft 64 are connected to fixed side plates 65, and the fixed side plates 65 are connected to the bottom of the fixed platform 3.

[0079] In this technical solution, the angle control component 6 can be used to adjust the angles of structures such as the fixed platform 3 and the moving platform component 4, thereby facilitating the storage of structures such as the fixed platform 3 and the moving platform component 4.

[0080] The rotating assembly 7 includes a central shaft 71 and a reinforcing side plate 72. A rotating hole is provided on one side of the fixed platform 3, and the central shaft 71 is rotatably connected to the fixed platform 3 through the rotating hole.

[0081] Both ends of the central shaft 71 are connected to reinforcing side plates 72, and one side of the reinforcing side plate 72 is connected to the side of the trolley frame 1.

[0082] In this technical solution, the rotating component 7 enables the fixed platform 3 to rotate.

[0083] In use, the extension and retraction of the angle control telescopic device 62 can drive the fixed platform 3 to rotate around the central axis 71, thereby driving the fixed platform 3 and the moving platform assembly 4 to rotate. The angle of the fixed platform 3 and the moving platform assembly 4 can be limited, which facilitates the storage and extension of the fixed platform 3 and the moving platform assembly 4.

[0084] Both sides of the trolley frame 1 are connected to protective netting 8.

[0085] In this technical solution, the protective mesh 8 can be used to protect the structure such as the trolley frame 1.

[0086] The length-controlling telescopic device 53 and the angle-controlling telescopic device 62 are devices such as hydraulic cylinders that have autonomous telescopic functions.

[0087] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
