The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0029] A type of work vehicle suitable for shotcreting slopes, such as Figure 1 It includes a frame 1, a moving wheel set 3, a straight module 2, a bracket 8, and a spray gun fixing assembly.

[0030] The frame 1 is made of several square tubes connected together, which can be welded or bolted. In this embodiment, the two sides of the frame 1 are triangular structures, and the middle is connected by a horizontal tie rod. The frame 1 is provided with a lug for connecting the traction rope 4. The lug is located on the front side of the frame 1, preferably two sets are provided on both sides, and the distance between them is greater than the range of the spray gun's translation.

[0031] Both the movable wheel set 3 and the linear module 2 are mounted on the frame 1, with the movable wheel set 3 positioned on both sides of the linear module 2, allowing the movable wheel set to travel outside the sprayed concrete range. At least four sets of movable wheel sets 3 are provided to ensure stability. The movable wheel set 3 is either an inflatable tire or a track wheel. When using track wheels, it should be used in conjunction with a track. The linear module 2 generally uses a screw linear module, which uses a motor to drive the left and right movement of the spray gun.

[0032] The support 8 and the slide of the linear module 2 are connected by a connecting structure 6, which is generally a bolt. The linear module 2 drives the support 8 to move, so as to realize the spraying of concrete in the lateral direction.

[0033] The bracket 8 is equipped with a rotating shaft 10 and a rotating shaft fixing assembly for locking the rotating shaft 10. The spray gun fixing assembly includes a rotating frame 9 and a spray gun connecting mechanism. The spray gun connecting mechanism is used to connect with the spray gun. The rotating frame 9 is connected to the spray gun connecting mechanism and installed on the rotating shaft 10, so that the angle of the spray gun connecting mechanism can be adjusted.

[0034] When applying to slopes at different angles, adjust the angle of the rotating frame 9 and the spray gun connection mechanism to keep them in a horizontal or other set working state.

[0035] The spray gun connection mechanism includes a spray gun fixing tube 5 and a spray gun fixing clamp 7. The spray gun fixing tube 5 is used to accommodate the spray gun and has an expansion joint. Several sets of spray gun fixing clamps 7 are set outside the spray gun fixing tube 5 to fasten the spray gun fixing tube 5.

[0036] The rotating frame 9 is connected to the bottom of the spray gun fixing tube 5 and is connected to the rotating shaft 10, as shown below. Figure 3 The rotating shaft fixing assembly includes a bolt mounting part 12 connected to the end of the rotating shaft 10. A bolt 11 is mounted on the bolt mounting part 12. The bolt 11 is in a tightened state. Tightening the bolt 11 causes its end to abut against the bracket 8, thereby locking the rotating shaft 10. Optionally, the rotating shaft fixing assembly is provided at one end or both ends of the rotating shaft.

[0037] The frame 1 is equipped with a spray gun connecting pipe fixing assembly, which includes a pipe fixing clamp 13. The pipe connecting pipe is fixed by the pipe fixing clamp 13, so that a part of the pipe can be reserved between the spray gun and the spray gun fixing clamp 7, reducing the resistance when the spray gun moves left and right, and reducing the pulling force of the pipe on the spray gun during the lifting process.

[0038] A slope shotcrete system includes the above-mentioned work vehicle suitable for slope shotcrete, a power unit and a towing rope 4, wherein the towing rope 4 is connected to the vehicle frame 1 and the power unit is connected to the towing rope 4.

[0039] The power unit is generally a winch.

[0040] During construction, the winch is first fixed at the top of the slope using ground anchors or counterweights, and the wire rope is reliably connected to the work vehicle. The shotcrete operation employs an innovative design: the spray gun is securely installed inside the circular tube of the spray gun fixing pipe 5, and tightened with clamps. Operators do not need to approach the slope; they only need to control the winch's lifting and lowering and the slider's lateral movement along the guide rail to achieve precise positioning for shotcreting. After completing one slope unit, the winch position can be adjusted to quickly move to the next work section. This achieves mechanized operation, significantly reducing manual labor intensity and greatly improving construction efficiency. It also effectively blocks construction dust, protecting the occupational health of workers.

[0041] Optionally, the slope shotcrete system also includes a track assembly, on which the movable wheel set 3 moves, enabling the system to work on uneven slopes. In use, the track is simply laid on the slope for the movable wheel set 3 to travel.
