[0002] In the field of tunnel construction, concrete is a key building material, and its delivery efficiency and accuracy directly affect the progress and quality of the project. Traditional concrete delivery methods have many limitations, especially in closed spaces such as tunnels.

This process is not only dangerous, but may also lead to unstable concrete mixing ratios and quality control due to human factors. Utility Model Content

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The present application embodiment discloses a concrete delivery vehicle for tunnel construction (hereinafter referred to as delivery vehicle). Figure 1 and Figure 2 The transport vehicle includes a vehicle body 1, a first containing bin 2 and a transport component 4.

[0036] like Figure 2 As shown, a plurality of wheels 11 are rotatably provided on the vehicle body 1. Through the vehicle body 1 provided with the wheels 11, the operator can transfer the first storage compartment 2 provided on the vehicle body 1 and adjust the position of the transport vehicle to adapt to different construction requirements and improve the problem of inconvenient concrete transport in the existing tunnel construction process. A traction interface 13 is provided on the vehicle body 1, and a hole is opened in the traction interface 13. The operator can quickly connect and transfer the transport vehicle through a traction vehicle with a hook.

[0037] In the embodiment of the present application, four wheels 11 are provided, and the four wheels 11 are rotatably provided under the vehicle body 1 through hinged ears; when the transport vehicle needs to be transferred, the operator can use a tractor with a hook, connect the tractor and the transport vehicle through the holes on the hook and the traction interface 13, and drive the transport vehicle to move through the tractor to transfer the position of the transport vehicle.

[0038] like Figure 2 As shown, a plurality of landing gears 12 are arranged on the periphery of the vehicle body 1, each landing gear 12 is arranged vertically, and the landing gear 12 includes a fixed portion 121, a movable portion 122 and a second driving member 123, the fixed portion 121 is connected to the vehicle body 1, the movable portion 122 is located below the fixed portion 121, and the second driving member 123 is used to drive the movable portion 122 to perform linear motion along the length direction of the fixed portion 121; when the transport vehicle needs to be fixed in position, the movable portion 122 can be driven to move by the second driving member 123, so that the movable portion 122 abuts against the ground, thereby limiting the position of the vehicle body 1 and ensuring the safety of the transport vehicle during concrete transportation.

[0039] like Figure 3 and Figure 4As shown, the first containing bin 2 is arranged on the top of the vehicle body 1 and connected to the vehicle body 1. The first containing bin 2 is provided with a feed port and a discharge port. A hopper 5 is provided at the discharge port. The hopper 5 is connected with the first containing bin 2 through the discharge port to guide concrete into the first containing bin 2 and reduce concrete splashing. The operator can inject concrete from the hopper 5 into the first containing bin 2 and draw out concrete from the discharge port.

[0040] In the embodiment of the present application, a stirring assembly 3 is arranged in the first containing bin 2, and the stirring assembly 3 includes a stirring head 31 and a first driving member 32. The stirring head 31 is rotatably arranged in the first containing bin 2 along the length direction of the first containing bin 2, and a driving rod is arranged at one end of the stirring head 31. The driving rod passes through the side wall of the first containing bin 2 and protrudes from the first containing bin 2. The output shaft of the first driving member 32 is connected to the driving rod, and the first driving member 32 is specifically a motor. The operator can drive the stirring head 31 to rotate through the first driving member 32, thereby stirring the concrete in the first containing bin 2, ensuring uniform mixing of the concrete, and preventing segregation of the concrete during transportation.

[0041] like Figure 2 and Figure 4 As shown, the conveying assembly 4 includes a frame 41, a conveying pipe 42, a conveying pump 43 and a second containing bin 44. The frame 41 is rotatably arranged on the top of the first containing bin 2. The frame 41 includes a plurality of support rods 411. Each support rod 411 is rotatably connected to an adjacent support rod 411. One of the support rods 411 located at the end of the frame 41 is rotatably connected to the top of the first containing bin 2. Telescopic rods 412 are connected between each of the plurality of support rods 411. The telescopic rods 412 are specifically electric hydraulic telescopic rods 412.

[0043] like Figure 2 and Figure 4 As shown, the second storage bin 44 is arranged at one end of the frame 41 away from the first storage bin 2, and the second storage bin 44 is connected to the conveying pipe 42. The concrete in the first storage bin 2 can be conveyed to the second storage bin 44. By adjusting the position of the frame 41, the position of the second storage bin 44 can be changed, so that the concrete can be conveyed to a position that the workers may not be able to reach, thereby improving the problem of inconvenience in conveying concrete in the existing tunnel construction process; at the same time, a nozzle 45 for conveying concrete to the tunnel wall is provided on one side of the second storage bin 44, and the nozzle 45 is connected to the second storage bin 44. The nozzle 45 connected to the second storage bin 44 can spray out the concrete in the second storage bin 44, further allowing the concrete to be conveyed to a position that the workers may not be able to reach, thereby further improving the problem of inconvenience in conveying concrete in the existing tunnel construction process.

[0044] A contact portion 46 for abutting against the tunnel wall is provided on one side of the second accommodating chamber 44, and a curvature is provided on a side of the contact portion 46 away from the second accommodating chamber 44. The contact portion 46 is specifically a rubber pad covering one side of the second accommodating chamber 44. The contact portion 46 abuts against the tunnel wall and can support the second accommodating chamber 44 while limiting the position of the second accommodating chamber 44, so that the concrete transport vehicle for tunnel construction can be more stably positioned in the tunnel, ensuring the working stability of the concrete transport vehicle for tunnel construction; the setting of the curvature enables the contact portion 46 to better fit the curve of the tunnel wall, thereby increasing the contact area between the concrete transport vehicle for tunnel construction and the tunnel wall, thereby enhancing the stability and positioning accuracy of the concrete transport vehicle for tunnel construction during the concrete spraying process.
