[0002] Wet spraying machine is a kind of concrete spraying equipment, which is mainly used for spraying concrete construction of underground projects such as tunnels, culverts, subways, foundation pit support, etc. The wet spraying machine uses hydraulic pumping to transport the concrete mixture to the nozzle through a pipeline. At the nozzle, the concrete mixture is fully mixed with high-pressure water mist and sprayed onto the working surface at a certain speed. The hydraulic pumping pressure of the traditional wet spraying machine is provided by an air compressor. A separate place must be provided on site to place the air compressor. The gas tank equipped with a set of air compressors and the air compressor itself occupy a lot of space, and it is also necessary to connect the wires separately. Once there are too many lines, it is easy to cause chaos on site, and multiple lines increase the risk of electricity use. When the wet spraying machine moves and sprays in the foundation pit, if it exceeds the length of the wire, the air compressor equipment must be moved, resulting in low construction efficiency. At the same time, when the air compressor pipeline is too long, it is easy for the pipeline to bend, resulting in excessive resistance when the air compressor is running, causing pipe bursting.

DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1: Figure 1-9 As shown, an integrated wet spraying machine device includes a traveling mechanism 1, a wet spraying machine 2 and an air compressor 3, wherein the wet spraying machine 2 and the air compressor 3 are respectively mounted on the right and left ends of the traveling mechanism 1, and a hanging structure 4 for hanging a traveling vehicle is mounted on the left end of the traveling mechanism 1. The device also includes a cable reel 5 and a power supply box 6 mounted on the traveling mechanism, wherein the cable reel 5 is located in front of an air storage tank 7, and the power supply box 6 is located on the right side of the cable reel 5. The cable reel 5 is mounted on the traveling mechanism 1 through a winding frame, and the winding frame is connected to the cable reel 5 through a rotating shaft, and a motor is connected to the rotating shaft, and the motor is mounted on the rear side of the winding frame. The power supply box 6 connects the power supply cable on the cable reel to its power inlet port, and the power supply cable is connected to the power output port of the diesel generator, and also includes an air storage tank fixedly connected to the traveling mechanism through two supporting frames. 7. The air outlet of the air compressor 3 is connected to the air storage tank 7, and the air storage tank 7 is connected to the air inlet end of the wet spraying machine 2. The mortar pushed out by the wet spraying machine is pneumatically sprayed through the air inlet end, and then the mortar is sprayed to the wall for bonding. The wet spraying machine and the air compressor are integrated on the same walking mechanism, which reduces the occupied space, can be conveniently moved on site and transported, and is also convenient for centralized power supply modules to supply power, avoiding too many lines causing clutter on site, reducing the risk of electricity use, and centralized placement, and also avoiding the problem of pipe bursting caused by excessive resistance during the operation of the air duct machine due to the long laying of the pipeline. Moreover, after the air storage tank is installed, the stability of the air pressure can be ensured, thereby improving the quality of the shotcrete. More importantly, it can save energy consumption and save more than 30% of electricity.

[0018] The wet spraying machine, air compressor, and gas storage tank are integrated and installed in one piece. By reasonably allocating space, the overall unit is optimized to the most reasonable space. A cable reel is set to centrally wind the unit wires. The wires are wound to the appropriate position according to the movement of the machine, so as not to cause the wires on site to be messy. Its working principle is to use the thrust generated by the air compressor to send the concrete from the conveying pipeline to the mixing pipe, and then form a thin flow through the pipeline to the nozzle through the compressed air. At the nozzle, a certain proportion of accelerator will be added (the accelerator is placed in a storage bucket, placed on the walking mechanism or on the ground on one side, and the storage bucket is connected to the accelerator inlet of the wet spraying machine through a pipeline). The addition of accelerator is continuously adjustable and can be infinitely adjusted according to the amount of spraying, and then directly sprayed onto the sprayed surface. The mechanical equipment is a three-in-one machine, electricity, and hydraulic, with simple operation and high construction efficiency.

[0019] According to the needs of the on-site foundation pit, the length of the conveying pipeline can be adjusted, and the machine does not need to be hoisted into the foundation pit, occupying a small working surface of the foundation pit, effectively reducing interference with other processes. In addition, the excavation of earthwork in the foundation pit generally leads to an uneven site, and the wet spraying machine is difficult to move, and sometimes a steel plate is required to move it. Since the equipment is above the foundation pit and uses four-wheel solid tires, it is easy to move, simple to operate and maintain, and can quickly move to the position of the designated spraying surface, which has significant advantages for secondary spraying and large-area initial spraying.

[0020] This equipment improvement aims to achieve the safety and operability of the unit and improve on-site construction efficiency.

Both ends of each transverse steel bar 407 are located between each pair of side steel bars 406 and are fixedly connected to each other. Multiple vertical bars 408 are welded on the outside between each pair of side steel bars 406. The hanging structure of the hanging joint and the isosceles tripod is adopted.
