[0032] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0033] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0034] The present utility model is an intelligent control scarifier for the invert of a tunnel, mainly used for scarifying the side wall of the invert of the tunnel. A walking frame is provided for the scarifier, and the scarifier can move on the walking frame according to the contour shape of the working surface of the invert of the tunnel, and can also adjust the height position distance according to the concave and convex surfaces of different heights to ensure the quality of the scarifying work.

[0035] As Figure 1 , Figure 2 , Figure 3 shown, the machine mainly includes a walking frame 1 capable of moving longitudinally, a scarifying assembly and a displacement adjustment assembly provided on the walking frame 1. The walking frame 1 mainly walks longitudinally along the extension direction of the tunnel. The walking frame 1 is the support of the whole machine, and both the scarifying assembly and the displacement adjustment assembly are installed on the walking frame 1. The scarifying assembly and the displacement adjustment assembly are functional components. The scarifying assembly mainly includes a scarifier for directly scarifying the side wall of the invert of the tunnel. The displacement adjustment assembly is used to drive the scarifying assembly to adjust the position displacement, and move according to the arc shape of the contour of the invert of the tunnel to ensure that scarifying construction can be carried out at each position. The spatial position of the scarifier can be adjusted, and the scarifying assembly adjusts the relative working height of the scarifier.

[0036] As Figure 4 , Figure 5As shown, specifically, the walking frame 1 includes a vertical frame beam 1-1 and a horizontal frame beam 1-2. One end of the vertical frame beam 1-1 and the horizontal frame beam 1-2 is in a fixed connection relationship, forming a fan-shaped contour. And further, an arc-shaped track beam 4 is arranged between the outer ends of the horizontal frame beam 1-2 and the vertical frame beam 1-1. The arc-shaped track beam 4 serves as the track for the displacement of the scarifying assembly. The fan-shaped structure formed by the walking frame 1 and the arc-shaped track beam 4 has good stability and is suitable for the construction of the tunnel invert.

[0037] Lower walking wheels 2 are arranged at the lower end of the walking frame 1 to enable the lower walking wheels 2 to travel on the ground. Usually, the power drive part is arranged at the lower walking wheels 2. Side walking wheels 3 are arranged at the outer ends of the upper part of the walking frame 1 to enable the side walking wheels 3 to travel on the side wall of the tunnel invert. In a specific implementation, one of the setting methods is to arrange the lower walking wheels 2 at the lower part of the vertical frame beam 1-1 and arrange the side walking wheels 3 at the outer side ends of the horizontal frame beam 1-2. Further, specifically, at least two lower walking wheels 2 are arranged to ensure stable operation. At least two side walking wheels 3 are also arranged to ensure stable operation. The two side walking wheels 3 are oppositely arranged on the longitudinal front and rear side surfaces of the walking frame 1-1. The side walking wheels 3 and the lower walking wheels 2 need to walk synchronously to ensure the stable walking of the whole machine. The corresponding setting can be to connect and drive the side walking wheels 3 and the lower walking wheels 2 through a universal joint and an inclined transmission shaft 20. Two side walking wheels 3 are arranged front and back, and two lower walking wheels 2 are arranged front and back. The side walking wheels 3 and the lower walking wheels 2 on the corresponding side are connected by a universal joint and an inclined transmission shaft 20. Specifically, as Figure 3 、 Figure 4 shown.

[0038] As Figure 4 shown, an arc-shaped track beam 4 is arranged on the walking frame 1. Preferably, two arc-shaped track beams 4 are oppositely arranged, enabling the scarifying assembly to be mounted on the arc-shaped track beam 4. Specifically, the scarifying assembly includes a moving seat 5 with moving wheels 16 and a scarifying machine 17. The moving seat 5 and the scarifying machine 17 are installed on the arc-shaped track beam 4 through the moving wheels 16.

[0039] The moving seat 5 moves on the arc-shaped track beam 4 driven by the displacement adjustment assembly. The displacement adjustment assembly includes an adjustment roller 9 and an adjustment rope 10. Specifically, the adjustment roller 9 is approximately arranged at the middle position of the walking frame 1. The middle part of the adjustment rope 10 is wound around the adjustment roller 9; then, one end of the adjustment rope 10 extends upward and continues to extend obliquely downward after passing around the fixed pulley 18 on the upper part of the walking frame 1 until it is traction-connected to the moving seat 5 of the scarifying assembly; the other end of the adjustment rope 10 extends downward and continues to extend obliquely upward after passing around the fixed pulley 18 on the lower part of the walking frame 1 until it is traction-connected to the moving seat 5 of the scarifying assembly. The adjustment roller 9 is connected with a driving assembly formed by a motor and a speed reducer, and the adjustment roller 9 can rotate forward and backward. When rotating forward and backward, the length of the adjustment rope 10 extending out of the adjustment roller 9 changes, so that the position of the moving seat 5 of the scarifying assembly changes. For example, when the adjustment roller 9 rotates forward, the upper adjustment rope 10 is retracted and the lower adjustment rope 10 is released. At this time, the scarifying assembly moves upward. When the adjustment roller 9 rotates backward, the upper adjustment rope 10 is released and the lower adjustment rope 10 is retracted. At this time, the scarifying assembly moves downward. In specific use, the scarifying assembly slowly adjusts its displacement under the action of the displacement adjustment assembly. The displacement adjustment assembly is similar to the principle of a winch.

[0040] Limiters are arranged at both ends of the arc-shaped track beam 4 to limit the movement of the scarifying assembly and prevent the scarifying assembly from moving out of position on the arc-shaped track beam 4.

[0041] As Figure 6 , Figure 7 shown, the scarifying assembly of this machine mainly further includes a scarifying machine 17, and the scarifying machine 17 is on the moving seat 5. This machine also has the function of adjusting the height of the scarifying machine 17. This can enable the machine to better adapt to the construction of different tunnel invert arches. Specifically, a height adjustment cylinder 6 is arranged on the moving seat 5, a height adjustment rod 17 is inserted into the height adjustment cylinder 6 from the lower end, and the scarifying machine 17 is fixedly arranged at the lower end of the height adjustment rod 7. Then, a height adjustment telescopic assembly 8 is fixedly arranged on the outer side surface of the height adjustment cylinder 6, the telescopic end of the height adjustment telescopic assembly 8 is connected to the height adjustment rod 7, and when the height adjustment telescopic assembly 8 expands and contracts, it can drive the height adjustment rod 7 to adjust its position, thereby realizing the position adjustment of the scarifying machine 17. The height telescopic assembly 8 is generally a hydraulic cylinder.

[0042] In the specific implementation of the present utility model, the side walking wheels 3 can be installed on the walking frame 1 through the telescopic assembly 12, and this setting can adjust the overall height and position form of the walking frame 1. The telescopic assembly is generally a hydraulic cylinder. The telescopic assembly 12 can also be a structure of a mechanical telescopic sleeve cooperating with fasteners.

[0043] The walking frame 1 of the utility model can also include a walking seat 14. The walking seat 14 acts as a walking trolley, and the lower walking wheel 2 is arranged on the walking seat 14, and a driving motor is also provided. The frame formed by the vertical frame beam 1-1 and the horizontal frame beam 1-2 is installed on the walking seat 14 through a height adjustment sleeve 15, and at the same time, a height adjustment component 19 is provided to drive the height adjustment. The moving end of the height adjustment component 19 is connected to the frame to drive the frame to adjust the height; it is similar to the height adjustment structure of the aforementioned roughening component. Specifically, Figure 8 shown.

[0044] Other supporting parts of the utility model include a lighting lamp 11, a dust cover 13 and a water mist nozzle. Specifically, a lighting lamp 11 is arranged on the upper part of the traveling frame 1 to increase the brightness of the work in the tunnel. A dust cover 13 is arranged at the position of the working head of the haircutting machine 17, and a water mist nozzle can also be arranged in the dust cover 13 to play a certain role in preventing dust pollution. At the same time, a water tank and a water pump are arranged on the traveling frame 1 to provide a water source for the water mist nozzle.

[0045] In the present invention, the height-adjusting telescopic assembly 8, the height-adjusting assembly 19 and the telescopic assembly 12 are usually configured as hydraulic cylinders. Accordingly, a hydraulic pump station is provided on the traveling frame 1 to provide hydraulic power for the hydraulic cylinders.

[0046] The utility model can also be equipped with a mobile vehicle for the chiseling machine, and a telescopic crane is arranged on the vehicle. When the chiseling machine is transferred to a small area, the chiseling machine is hoisted on the vehicle by the telescopic crane, and then hoisted off the vehicle when it is moved to the work site. A hanging seat is arranged on the upper part of the traveling frame of the chiseling machine. A high-pressure cleaning machine is arranged on the mobile vehicle for on-site washing of the chiseling machine. The mobile vehicle and the fully automatic chiseling machine are arranged separately, and can also be integrated.

[0047] The chiseling machine can be fully automatically controlled by PLC and is also equipped with wireless remote control.

[0048] The traveling frame of the utility model can provide stable support, and through the height adjustment of the chiseling machine in the chiseling assembly, the displacement adjustment of the displacement adjustment assembly and the height adjustment of the traveling frame, the working head of the chiseling machine can be stably engaged on the chiseling surface, thereby ensuring the chiseling quality; and the utility model can well adapt to the chiseling construction of various different tunnel inverts.
