Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, characteristics and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Example 1

As shown in fig. 1, an automatic concrete spraying and recycling integrated device for tunnel wet spraying comprises a wet spraying trolley 1, a wet spraying concrete device 2 arranged on the wet spraying trolley 1, a collecting tray 3 and a conveying belt 4 for conveying concrete in the collecting tray 3 to the wet spraying concrete device 2. The structure connects the wet spraying concrete structure and the concrete recycling structure which can work independently, and realizes the integration of spraying concrete and recycling on the same movable device.

Specifically, the wet concrete spraying device 2 comprises a high-pressure pump 2-1, a stirring barrel 2-2 and a concrete sprayer 2-3; the high-pressure pump 2-1 is used for providing high-pressure gas for the concrete injector 2-3, and the stirring barrel 2-2 is used for providing concrete materials for the concrete injector 2-3; one end of the conveyor belt 4 close to the wet concrete spraying device 2 is arranged above the stirring barrel 2-2. The structure can enable the recycled concrete and the aggregate to be mixed again for continuous use, and reduces the waste of the concrete dropped during wet spraying and the pollution to the environment.

Wet spraying platform truck 1 in this embodiment can directly use the freight train repacking, removes the carriage of freight train, changes into no boxed car, has placed wet spraying concrete device 2, catch tray 3 and is used for connecting wet spraying concrete device 2 and catch tray 3's conveyer belt 4 on the car hopper of freight train.

On the basis, in order to improve the spraying effect of the wet spraying concrete, as shown in fig. 1, the wet spraying concrete device 2 further comprises a hydraulic lifting device 2-4 for changing the height of the concrete sprayer 2-3, and the concrete sprayer 2-3 is fixedly connected to the hydraulic lifting device 2-4.

Preferably, the wet spraying trolley 1 is provided with a displacement sensor 2-6 for detecting the distance between the wet spraying trolley 1 and a sprayed rock surface, and when the displacement sensor 2-6 detects that the distance between the wet spraying trolley 1 and the rock surface to be sprayed is too large, the height of the lifting device 2-4 can be increased or the pressure of the high-pressure pump 2-1 is increased to realize effective spraying of the concrete sprayer 2-3; similarly, when the displacement sensor 2-6 detects that the distance between the wet spraying trolley 1 and the rock surface to be sprayed is too small, the effective spraying of the concrete sprayer 2-3 can be realized by reducing the height of the lifting device 2-4 or by reducing the pressure of the high-pressure pump 2-1. Displacement sensor 2-6 use KTC electronic ruler straight line bluetooth displacement sensor in this embodiment. The structure can complete the effective injection of the concrete injectors 2-3, avoid the problem of poor forming effect of the sprayed concrete due to the fact that the injection distance cannot meet the requirement caused by inaccurate visual inspection, and save manpower and material resources.

On the basis, as shown in figure 1, a water tank 2-5 is arranged below the stirring barrel 2-2. The water tank 2-5 can provide a water source for the dry-mixed concrete in the mixing tank 2-2, and saves space.

On the basis, in order to better realize the integration of concrete spraying and recovery, as shown in fig. 2, the conveyor belt 4 is arranged at the bottom of the collecting tray 3, and the dropped concrete enters the collecting tray 3 and then falls on the conveyor belt 4 for transportation. This structure requires the width of the conveyor belt 4 to be wide enough to completely cover the bottom of the collecting tray 3, but generally, the collecting tray 3 with a wide width needs to be provided because the area of the concrete sprayed in the tunnel is large, and when the width of the conveyor belt 4 is too large, the installation and maintenance costs of the conveyor belt 4 increase, and the conveying efficiency is greatly reduced, so in order to improve the conveying efficiency of the conveyor belt 4, as shown in fig. 3 and 4, a channel 3-2 for passing the concrete is formed on the bottom plate 3-1 of the collecting tray 3, and the conveyor belt 4 is arranged below the channel 3-2.

On this basis, in order to recover the concrete that has fallen sufficiently completely, the floor 3-1 is higher at the end remote from the tunnel 3-2 than at the end close to the tunnel 3-2, as shown in fig. 5. Preferably, the bottom plate 3-1 is an arc-shaped plate, and the opening direction of the arc-shaped plate faces the opening at the upper end of the collecting tray 3. The structure can enable the concrete in the collecting tray 3 to quickly slide off, and meanwhile, the condition that the concrete is accumulated at the bottom of the collecting tray 3 is avoided.

On this basis, as shown in fig. 4 and 5, the bottom plate 3-1 of the collecting tray 3 is provided with a vibrator 5. This configuration helps to drop the granules as quickly as possible onto the conveyor belt 4 and also reduces the problem of incomplete recovery due to the granules sticking to the inner wall of the collection tray 3.
