Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning construction machinery such as power shovels and bulldozers.

0002

[Prior Art] Construction machines such as power shovels and bulldozers are used for earthwork work at civil engineering sites, etc. by attaching work equipment to the vehicle bodies that run using track-type running devices, and the track-type running devices are attached to truck frames. A crawler belt is wrapped around the attached starting wheel and idler wheel, and the crawler belt is supported by upper and lower roller wheels attached to the truck frame. As mentioned above, when construction machinery is used for civil engineering work, dirt adheres to and accumulates on the track-type traveling device, especially on the surface of the track, between the back of the track and the top and bottom surfaces of the truck frame, on the starting wheels, and on the idler wheels. It is necessary to clean dirt and sand that has accumulated during inspection and repair or during transportation by truck, etc., and conventionally, workers hold a hose and spray high-pressure water to clean it.

0003

[Problems to be Solved by the Invention] Cleaning the earth and sand is a very arduous task as the workers may be splashed with water and mud, staining their bodies. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cleaning device for construction machinery that can solve the above-mentioned problems.

0004

[Means for Solving the Problems] A cleaning device for construction machinery comprises a main body 2 that can freely run along a frame main body 1, and a nozzle 3 that can move up and down and swing vertically along this main body 2.

[Operation] By moving the nozzle 3 while swinging up and down and moving it a predetermined stroke, or by moving the nozzle 3 downward and moving it again while swinging up and down, high-pressure water is supplied to the track-type traveling device of the construction machine. Cleans automatically and efficiently by spraying in a wave pattern.

[0005]

[Example] As shown in Figure 1, a substrate A such as an iron plate
A cleaning device B is disposed above, and this cleaning device B includes a long frame main body 1 disposed parallel to the construction machine C, a main body 2 that can freely run along the frame main body 1 in the longitudinal direction,
It consists of a nozzle 3 installed on the main body 2 so as to be able to swing up and down and move up and down.A cable 5 is stretched between a pair of vertical supports 4, 4 attached to both longitudinal sides of the frame main body 1. A hose 7 and a control cable 8 are connected to a slider 6 that can freely slide along a slider 5 so that the hose 7 and the control cable 8 hang down at intervals, so that the hose 7 and the control cable 8 can be smoothly moved when the main body 2 runs. It is designed to move. As shown in FIGS. 2 and 3, the frame body 1 has horizontal members 11 attached to both longitudinal ends of a long rail 10 having an I-shaped cross section, and caster wheels 12 at both ends of each of the horizontal members 11. The frame body 1 is attached so that it can run along the board A. As shown in FIGS. 2 and 3, the main body 2 includes:
A vertically elongated main body frame 14 is attached to a movable frame 13 that can freely run along the rail 10, and the movable frame 13 includes a lower guide roller 15 that contacts the lower surface of the rail 10, a side guide roller 16 that contacts the side surface of the rail 10, A driving roller 17 is also provided which contacts the upper surface of the rail 10. Two of the drive rollers 17 are attached to a pair of shafts 18 as shown in FIG. 4, and the pair of shafts 18 are interlocked with a sprocket 19 and a chain 20, and one shaft 18 is connected to a sprocket 21 and a chain 20 as shown in FIG. It is connected to a travel motor 25 via a transmission mechanism 23 such as 22, a speed reducer 24, etc.

A pair of vertical frames 26, 26 are provided within the body frame 14 as shown in FIGS. 4, 6, and 7, and a horizontal frame 27 is provided between the upper portions of the pair of vertical frames 26, 26.
is fixed to a horizontal frame, and this horizontal frame 27 and the movable frame 13
A feed screw 28 and a guide rod 29 are installed parallel to each other, and a support frame 30 is supported along the guide rod 29 so as to be vertically movable. The feed screw 28 is connected to a transmission mechanism 3 such as a sprocket 31 and a chain 32.
A feed nut 35 is connected to the vertical feed motor 34 attached to the horizontal frame 27 via the support frame 30, and is screwed onto the feed screw 28. A feed nut 35 is rotatably supported by the support frame 30, and is supported when the vertical feed motor 34 is driven. frame 3
0 moves up and down along the guide rod 29, and its vertical movement stroke can be detected by the rotation detector 40 of the feed screw 28, and the upper and lower limit switches 36 and 37 for detecting the upper and lower limits of the support frame 30 are installed. It is attached to one vertical frame 26. A shaft 38 is provided on the support frame 30 so as to be rotatable in forward and reverse directions by a swing motor 39, and the nozzle 3 is attached to the shaft 34. This nozzle 3 may be of a type that sprays high-pressure water straight or may be of a type that sprays high-pressure water in a diffused manner.

Next, the cleaning operation will be explained. Traveling motor 2
5 to move the movable frame 13 and main body frame 14 along the rail 10, the nozzle 3 is positioned at the end of the crawler-type traveling device D of the construction machine C. At this time, the support frame 30 is moved upward and the nozzle 3 is moved to the track type traveling device D.
position at the top of the While driving the traveling motor 25 to make the movable frame 13 and main body frame 14 travel along the rail 10, the nozzle 3 is oscillated up and down by the oscillating motor 39, and high-pressure water is supplied from the nozzle 3 to the track-type traveling device D in a waveform. Spray in a trajectory. When the nozzle 3 reaches the other end of the track-type traveling device D, the nozzle 3 is lowered together with the support frame 30 by a distance shorter than the vertical swing amount, and the traveling motor 25
is driven in the opposite direction to that described above, and the nozzle 3 injects high-pressure water in a waveform trajectory. At this time, the parts that could not be cleaned in the previous cleaning because the previous waveform trajectory and the current waveform trajectory overlap are cleaned. When the nozzle 3 reaches one end of the track-type traveling device D, the nozzle 3 is lowered slightly together with the support frame 30, and the above-described operation is repeated. In the above operation, when cleaning a heavily soiled area, such as a crawler track or an upper/lower wheel area, the nozzle swing speed and running speed are slowed down to increase the cleaning density. This control may be stored in advance in the controller in accordance with the size of the crawler-type traveling device, and may be performed automatically.

[0008]

[Effects of the Invention] By moving the nozzle 3 while swinging it up and down, and moving it by a predetermined stroke, moving the nozzle 3 downward and moving it again while swinging it up and down, high-pressure water is supplied to the track-type traveling device of the construction machine. Cleans automatically and efficiently by spraying in a wave pattern.
