[Detailed Description of the Invention] The present invention relates to an improvement of a self-propelled vehicle washing device.

Conventionally, as a self-propelled vehicle washing device that cleans a vehicle by running on its own while spraying a cleaning liquid, a vehicle that runs on the floor of a vehicle entry space A and sprays cleaning water upward is known. 2. Description of the Related Art A bottom surface cleaning device and a gate-type vehicle cleaning device in which a gate-shaped self-propelled body moves across the vehicle to clean the top and side surfaces of the vehicle are known. However, these conventional devices have the disadvantage that the former can only clean the underside of the vehicle, and the latter cannot clean the underside of the vehicle. In addition, the latter in particular has the drawback that the device is large and requires a large installation space.

The present invention has been developed in consideration of the above-mentioned drawbacks, and a self-propelled vehicle cleaning device is manufactured that can clean the entire surface of the vehicle, including the underside and front and rear surfaces, using a single device with a simple configuration.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the figure, 2 is a self-propelled platform, and this self-propelled platform 2 is guided by a guide 1 provided in the vehicle entry space A and moves around the vehicle that enters the vehicle entry space A. ing. This guide 1 is made up of pipe rails laid in a U-shape on the floor.
It may be laid in an O-shape around the circumference, and further, rails of other shapes or guide grooves may be used instead of pipe rails.

The self-propelled mechanism of the above-mentioned self-propelled platform 2 has rolling wheels 7, 7 mounted on the guide 1 so as to straddle the guide 1 on the front bottom surface of the self-propelled platform 2, and on the rear bottom surface. A driving wheel 9 rotated by a motor 4 is provided,
The drive wheels 9 are configured to rotate on the floor, thereby self-feeding. Although not clearly shown in the figure, the rotating shafts of the wheels 7, 7 are rotatably connected to the self-propelled base 2, so that the self-propelled base 2 can be connected to the guide 1.
It is designed to be able to run on its own along the curves of the road.

On the self-propelled platform 2, there is a cleaning water supply pipe 5,
A power cord 6 and a take-up reel 3 are arranged. This take-up reel 3 is biased in the take-up direction by a coil spring or the like (not shown), and connects a cleaning water supply pipe 5 whose one end is fixed to a fixed part B of the vehicle entry space A and a power cord 6. When the self-propelled platform 2 moves away from the fixed part B, it is sequentially rolled back onto the floor surface of the vehicle entry space A, and the self-propelled platform 2 moves away from the fixed part B.
When approaching the winder, it is wound up sequentially starting from the floor. Although two take-up reels 3 are shown in the figure, one take-up reel 3 connects the cleaning water supply pipe 5.
and the power cord 6 may be wound together. Note that 26 is a guide roller between the washing water supply pipe and the power cord 6.

Further, on the self-propelled platform 2, there is provided a horizontally movable platform 8 that is movable in the direction toward and away from the vehicle entered. Although not shown in the figure, the horizontally movable table 8 has a rack that engages with a gear connected to a handle, and moves forward and backward by the rotation of the handle. figure,
When obtained, it may be directly pushed out or pulled back from the self-propelled platform 2. However, it is desirable that the horizontally movable table 8 be able to be fixed to the self-propelled table 2 at a predetermined position with fixing screws or the like in order to avoid displacement while the self-propelled table 2 is moving.

At the tip of the horizontal moving table 8, there is a vertical guide tube 12 through which a connecting pipe 10 connected from the central axis of the take-up reel 3 via a rotary joint 25 is inserted.
It is disposed so that it can be raised and lowered via a lifting device 11 whose raising and lowering position can be adjusted.

As shown most clearly in FIG.
7, a rack 13 is arranged in the longitudinal direction of the vertical guide tube 12, and a handle 1 of the gear box 37 is arranged.
4 is connected to a pinion that engages with the rack 13, and when the handle 14 is rotated, the vertical guide tube 1
2 can be raised and lowered.

Further, at the tip of the horizontal moving table 8, a guide outer cylinder 38 is provided.
is rotatably erected, and the vertical guide tube 12 passes through the guide outer cylinder 38. This guide outer cylinder 38 is provided with a fixing screw 15, and the vertical guide tube 12 raised and lowered by the rotation of the handle 14 is fixed by the fixing screw 15. However, in the case where the pinion is an ohmic gear This fixing screw 15 is unnecessary. Furthermore, an arm 29 located below the horizontal moving table 8 is provided at the lower end of the guide outer cylinder 38, and a spring 27 is hung between the arm 29 and the horizontal moving table 8 to keep them in parallel positions. When the nozzle pipe 22 (to be described later) collides with something, the nozzle pipe 22 to the arm 29 rotate against the restraint of the spring 27, and this rotation can be detected by the proximity switch 28 disposed at the tip of the arm 29. It's becoming like that.

At the upper end of the vertical guide tube 12, a holding tube 17 for connecting the tip of the connecting pipe 10 is held above the vertical guide tube 12, and the holding tube 17 is tilted forward of the vertical guide tube 12. A tilt adjuster 16 is connected thereto. The illustrated inclination adjuster 16 includes an arm 32 having one end pivotally connected to a slider 30 having a fixing screw 31 for sliding the vertical guide tube 12 as a guide and fixing it at a desired rocking position; Arm 3 fixed to the upper end of
3 and an arm 34 to which the holding tube 17 is fixed at one end, and the other ends of the arms 32 and 33 are pivotally connected to two points on the other end of the arm 34, forming a link mechanism. When the holding tube 17 is tilted, the slider 30 is guided by the vertical guide tube 12, and the slider 30 is fixed to the vertical guide tube 12 with the fixing screw 31 at a desired angle of inclination. Incidentally, this inclination adjustment tool 16 is not limited to the illustrated example; a disk is fixed to the upper end of the vertical guide tube 12, an arc-shaped long hole is arranged in this disk, and the holding tube 17 is adjusted to the desired length of the long hole. It may be made so that it can be screwed into position.

Further, at the tip of the holding tube 17, the holding tube 1
This arm tube 20 is connected to an arm tube 20 via a rotary tube joint 18 that can be rotated around an axis 7 as a central axis.
is the washing water supply pipe 5 and the connecting pipe 10.
is a bendable pipe, whereas non-bendable pipes such as metal pipes are used. Also, 19
is a fixing screw that fixes the rotational position of the arm tube 20 by the rotary tube joint 18.

Furthermore, at the distal end of the arm tube 20, as most clearly shown in FIG.
Nozzle pipes 22 in which nozzles 23, 23, 23, . . . are arranged side by side are connected via 1. In addition, 24 is a stopper for adjusting the rotational position of the nozzle pipe 22;
39 is a fixing screw that fixes the nozzle tube 22 in parallel to the arm tube 20.

Reference numeral 35 in the figure is a control panel that controls the self-propelling of the self-propelled platform 2, which rotates the motor 4 in forward and reverse directions according to the signal from the aforementioned proximity switch 28, and changes the self-propelled direction when the nozzle pipe 22 collides with something. It has been done. Also,
Although not shown, limit switches are placed before and after the self-propelled base 2 in the self-propelled direction, and a stopper is placed at the end of the guide 1 or at a desired position of the guide 1, and the self-propelled base 2 touches this stopper when it travels on its own. This limit switch detects this and rotates the motor 4 in the reverse direction. Furthermore, this control panel 35
calculates the number of forward and reverse rotations of the motor 4, and stops self-propulsion after it has self-propelled back and forth within a certain range a predetermined number of times,
Although not shown in the diagram, turning on and turning on the power to the motor 4
The OFF and ON/OFF of energization to the wash water solenoid valve are linked. Further, numeral 36 indicates a protruding piece for hooking the cleaning water supply pipe 5 and the power cord 6.

Since the self-propelled vehicle washing device of the present invention has the above-mentioned structure, the self-propelled vehicle cleaning device of the present invention has the structure shown in FIG.
When moving to the left side of the figure, the cleaning water supply pipe 5 and power cord 6 are rewound onto the floor from the take-up reel 3, and when the self-propelled table 2 is moved in the opposite direction, the cleaning water is supplied on the floor. Reel 3 takes up pipe 5 and power cord 6
I'm going to wind it up. Then, when the self-propelled table 2 self-propels to the right in the figure and passes the fixed part B, the wound washing water supply pipe 5 and power cord 6 are then rewound onto the floor surface. Therefore, this self-propelled platform 2 has a cleaning water supply pipe 5 and a power cord 6 placed on the floor.
Therefore, the self-propelled platform 2 does not require a large amount of power for self-propulsion, and the self-propelled platform 2 can be made smaller and lighter.

In addition, the nozzle 23 of the self-propelled vehicle cleaning device according to the present invention,
23, 23... The nozzle pipes 22 arranged in parallel are the self-propelled platform 2
When connecting to the horizontal moving table 8, lifting device 11
Since the nozzle is provided with a vertical guide tube 12, an inclination adjuster 16, and rotary pipe joints 18 and 21, the injection direction and injection position of the nozzle can be set in various ways. That is, by installing the nozzle pipe 22 in the state shown by the solid line in FIG. 2, the side surface of the vehicle can be washed. However, in this case, the nozzle pipe 22 is connected to the rotary pipe joint 2.
1 so that it overlaps with the arm tube 20. Next, the nozzle pipe 22 is made horizontal as shown by the chain line X using the inclination adjuster 16, so that the top surface of the vehicle can be washed. Next, using the same inclination adjustment tool 16, set the nozzle pipe 22 to the state shown by the chain line Y (it is inclined in the figure, but in reality, it is vertical with the tip side closer to the self-propelled platform 2 side). , the side of the vehicle can be washed (washing of the lower side than the above-mentioned side washing).
In addition, when changing the nozzle pipe 22 from the state shown by the chain line X to the state shown by the chain line Y, the nozzle 2 may be directed toward the vehicle using the rotary pipe joint 18. Then, by rotating the nozzle tube 22 at right angles to the arm tube 20 using the rotary tube joint 21 to bring it into the state shown by the chain line Z in the figure, the underside of the vehicle can be cleaned. Note that each position of the nozzle pipe 22 shown in FIG. 2 can be moved up and down by the lifting device 11, and can be moved toward and away from the vehicle in the lateral direction by the horizontal moving table 8, so that the nozzle 23 can be positioned farthest from the surface to be cleaned. Can be set at an effective distance.

Therefore, in the present self-propelled vehicle cleaning device, if the guide 1 is arranged in the vehicle entry space A and the self-propelled platform 2 with a simple configuration as described above is prepared, one device can be installed according to the purpose of cleaning. It can be used to clean various areas (all surfaces) of the vehicle.

Furthermore, since the present invention allows one nozzle pipe 22 to be installed in various positions as described above,
The entire device has the advantage of being able to be manufactured in a small size.
Downsizing is not only advantageous in terms of manufacturing costs and operating power, but also allows for a larger work space when performing inspection and maintenance work on vehicles in the vehicle entry space A, since the cleaning equipment does not take up a large area. It also has advantages.
