Prior to the description with reference to the drawings, the accompanying drawings reveal that it is a conceptual and schematic illustration for convenience to explain the tunnel cleaner of the present embodiment.

As shown in the drawings in Figures 1 to 10, the tunnel cleaner according to the present embodiment, for example, may be mounted and used in a general vehicle 120, construction machines, trains and the like. Of course, the vehicle 120 itself equipped with the tunnel cleaner of the present embodiment may form one tunnel cleaner.

The tunnel cleaner is largely mounted on one side of the vehicle 120, the rotary washing brush 130 for washing the inner wall (110a) of the tunnel 100 while rotating in contact with the inner wall (110a) of the tunnel 100, Frame structure 140 for supporting the rotary cleaning brush 130, the rotary drive unit 150 is coupled to the frame structure 140 to drive the rotary cleaning brush 130, the tunnel is coupled to the frame structure 140 A plurality of injection nozzles 160a, 160b, 160c for spraying cleaning water or detergent to the inner wall 110a of the 100, and the vehicle 120 and the frame structure 140 are provided and rotated with respect to the vehicle 120. The position variable to change the position of the brush 130 includes a variable stage (not shown).

First of all, with respect to the tunnel 100, the tunnel 100 takes the form of a cave such that a train or vehicle 120 of the present embodiment can pass, as shown in FIG. Although the inner wall 100a of the tunnel 100 is round in FIG. 1, the inner wall 110a of the tunnel 100 may be processed into a flat surface.

As described above, the vehicle 120 is a parent to which the tunnel cleaner of the present embodiment is mounted and is a means for moving the tunnel cleaner. Accordingly, the vehicle 120 may be a general vehicle 120, a construction machine, a train, or the like.

In detail with respect to the vehicle 120, the vehicle 120 is provided with a water tank 121 as a substantially large volume structure, as shown in FIG. 2. The water tank 121 provides water to some of the injection nozzles 160a and 160b by a structure to be described later.

In addition, the detergent tank 124 is further provided around the water tank 121. The detergent tank 124 provides detergent to some other spray nozzles 160c.

The vehicle 120 has a pump 123a controlled by the controller 122 so that water and detergent from these water tanks 121 and the detergent tank 124 can be provided to the spray nozzles 160a, 160b, 160c. 123b) is further provided.

Thus, a washing operation is started so that the controller 122 drives the pumps 123a and 123b so that the water and the detergent from the water tank 121 and the detergent tank 124 are sprayed to the corresponding spray nozzles 160a, 160b and 160c. Through it can be injected into the inner wall (110a) of the tunnel 100.

In addition, one side of the vehicle 120, the wall distance measurer 125 for measuring the distance from the inner wall (110a) of the tunnel 100 with respect to the vehicle 120 is further provided.

Referring to FIG. 2, one wall distance measurer 125 is mounted on the front right side of the vehicle 120, but this is only one embodiment. Therefore, in addition to the position shown in FIG. 2, the wall distance measuring instrument 125 may be provided with a plurality of positions.

The vehicle 120 may move freely inside the tunnel due to the wheels 110a, thus increasing the efficiency of cleaning the inner wall 110a of the tunnel 100 to shorten the washing time.

The rotary cleaning brush 130 serves to clean the inner wall 110a of the tunnel 100 while rotating in contact with the inner wall 110a of the tunnel 100.

As shown in FIG. 4 and FIG. 5, it is supported by the frame structure 140, and has a structure in which a plurality of layers are arranged along the height direction. The rotary washing brush 130 is mainly made of a cloth or rubber material when the inner wall 110a of the tunnel 100 is struck, while the washing efficiency is increased while preventing the inner wall 110a of the tunnel 100 from being damaged. do.

First, the frame structure 140 supporting the rotary washing brush 130 will be described.

4 and 6, the frame structure 140 is disposed in the form surrounding the outer side of the rotary cleaning brush 130, and the upper and lower frames 140a and 140b. And side frames 140c and 140d.

The side frames 140c and 140d are vertically connected at the ends of the upper and lower frames 140a and 140b, and are spaced apart from the side frames 140c and 140d around the side frames 140c and 140d, respectively. The dummy frames 140e and 140f are further provided in parallel with the side frames 140c and 140d at the position. In the side frames 140c and 140d and the dummy frames 140e and 140f, the plurality of injection nozzles 160a, 160b and 160c described above are provided at equal intervals with a spaced interval therebetween.

Although it is not necessary to follow the structure of the drawing as it is, the injection nozzles 160a and 160b coupled to the side frames 140c and 140d are places where water from the water tank 121 provided in the vehicle 120 is ejected. The spray nozzle 160c coupled to the dummy frames 140e and 140f is a place where detergent is sprayed from the detergent tank 124 provided in the vehicle 120.

That is, as can be seen through Figure 8, the water from the water tank 121 through the water lines (L1, L2), and the detergent from the detergent tank 124 through the detergent lines (L3, L4) Can be directed to the corresponding injection nozzle (160a, 160b, 160c), respectively.

Of course, the water and detergent sprayed from the plurality of injection nozzles (160a, 160b, 160c) are directed to the inner wall (110a) of the tunnel 100, respectively, after the rotary washing brush to the inner wall (110a) of the tunnel 100 130 is to wash the inner wall (110a) of the tunnel 100 while hitting the inner wall (110a) of the tunnel (100).

At this time, among the plurality of injection nozzles (160a, 160b, 160c), in particular, in the case of the injection nozzles (160a, 160b) is sprayed with water, they can be operated by the controller 122 at a time difference. For example, in FIG. 5, the injection nozzles 160a positioned in the side frame 140c on the left side may be primarily sprayed, and the injection nozzles 160b positioned in the side frame 140d on the right side may be controlled to be injected secondarily. .

That is, when water is primarily directed to the inner wall 110a of the tunnel 100 by the spray nozzles 160a and at the same time the detergent is directed to the inner wall 110a of the tunnel 100 through the spray nozzle 160c, The rotary washing brush 130 rotates using water and detergent to wash the inner wall 110a of the tunnel 100.

When the cleaning is completed, this time water may be sprayed by the injection nozzles (160b) secondary to the inner wall (110a) of the tunnel 100 may finish the cleaning of the position. Of course, the order of these structures and operations may be changed as needed. That is, the injection nozzles 160a and 160b may be configured to operate simultaneously at once instead of being divided into primary and secondary operations, respectively.

The rotary drive unit 150 serves to rotate the rotary washing brush (130). As shown in FIG. 7, the rotary drive unit 150 includes a hydraulic motor 151 coupled to the upper frame 140a, a rotary shaft unit 152 forming a rotary shaft center of the rotary washing brush 130, and hydraulic pressure.

Accordingly, when power is applied to the hydraulic motor 151 by a separate control signal and the motor shaft 151a is rotated, the rotating shaft portion 152 is rotated by the connecting portion 153, thereby rotating the washing brush 130. Will be able to rotate.

At this time, it is more convenient that the hydraulic motor 151 is adopted that the motor shaft 151a can rotate in both forward and reverse directions for the convenience of operation. When the motor shaft 151a of the hydraulic motor 151 rotates in both forward and reverse directions, the rotary washing brush 130 may also rotate in both forward and reverse directions, thereby increasing the efficiency of the work.

Meanwhile, as shown in FIG. 1, the size of the vehicle 120 and the tunnel washer is substantially determined, but the inner wall 110a of the tunnel 100 to be cleaned is not only different for each tunnel 100 but also the position to be cleaned. It's also different.

Therefore, if the position of the rotary washing brush 130 in the tunnel cleaner is fixed, only the limited portion can be washed.

Therefore, the position of the rotary washing brush 130 to cover all of the inner wall (110a) of the tunnel 100 should be varied as necessary, which is the position variable variable stage. That is, the position variable stage is provided in the vehicle 120 and the frame structure 140, and serves to change the position of the rotary washing brush 130 with respect to the vehicle 120.

Therefore, a higher washing in the tunnel 110 is possible.

On the contrary, if the Shanghai East Bar 184 coupled to the Hydraulic Cylinder 182 is driven by the hydraulic cylinder 182 to move downward, the upper and lower rods 183a and 183b coupled to the Shanghai East Bar 184. By the frame structure 140, the entire rotary washing brush 130 can be moved to the lower side.

Meanwhile, a vertical angle adjuster 197 is further provided on the upper rod 193a of the elevating means 180. Due to the vertical angle adjuster 197, there is an advantage in that the vertical angle between the lifting and lowering structures can be precisely adjusted.

Finally, the spray angle adjusting means 190 is a means for adjusting the spray angles of the spray nozzles 160a, 160b, 160c with respect to the inner wall 110a of the tunnel 100 by locally rotating the frame structure 140. It has a structure as shown in Figs. 5, 6, 9 and 10.
