The second magnet (27) and the second switch (29) form an emergency stop proximity switch, and are normally separated from each other in the front-rear direction. Reference numeral (31) is a traveling arm which has a downward U-shaped cross section with an opening on the lower surface and which is curved in the same arc shape as the guide arm (17).

The traveling rollers (33) are respectively provided at the inner and outer ends of a pair of front and rear support plates (32) (32) which are vertically extended from the outer end of the vertical piece of the traveling arm (31). Is pivoted (see Figure 3). Each traveling roller (33) is rotatably fitted on both rails (18) (18) of the guide arm (17), whereby the traveling arm (31) can travel on the guide rail (17). Is supported by. The inner end of the traveling arm (31) is always located inward of the wheels (5) of the vehicle (4).

Inside the traveling arm (31), an injection pipe (34) whose base end (left end in FIG. 1) is connected to a high-pressure water source by a flexible pipe (not shown) is attached by a mounting bracket (35). There is. The two nozzles (36) mounted side by side on the upper surface of the inner end of the injection pipe (34) are inclined forward and rearward and inward, and at the inner end of the traveling arm (31), Is located below the vehicle (4).

Slightly outside the nozzle (36), the nozzle (36) provided on the upper surface of the injection pipe (34) projects upward from substantially the center of the traveling arm (36), and the nozzle (36) of the vehicle (4). It is located below the side. A third magnet (37) is attached to the outer end of the upper surface of the traveling arm (31) and a third switch (38) attached to the inner end of the outward U-shaped piece (19) of the guide arm (17). This constitutes a proximity switch for detecting the upper limit of the traveling arm (31).

As shown in FIG. 7, each of the pulleys (23) provided in the guide arm (17) has one end that is attached downwardly from the lower surface of the central portion of the proposed arm (17) to provide a fastener ( 39) to the first wire (41) which is fixed to the inner surface of the traveling arm (31) slightly outside the central portion of the traveling arm (31) by being fastened via the compression spring (40). , Both ends are respectively laid around the inner surface of the inner end of the guide arm (17) and the second wire (42) secured to the inner surface slightly inward of the center of the traveling arm (31). There is.

Therefore, when the upper link (81) and the lower link (25) are swung by the rotary motor (80), the traveling arm (31) moves twice as much as the moving amount of the lower end of the lower link (25). Travel inward and outward along the guide rail (17) with the strike.

When the inner end of the traveling arm (31) comes into contact with the rear wheel (5) (the wheel on the left side in FIG. 8), the traveling arm (31) and the guide arm (17) move to the support tube (9). It swings backward around the inner pivot (11), and the downward rod (13) slightly extends while extending the tension spring (16) via the rear holding piece (15a) and the swing plate (15). Rock. At this time, the front oscillating plate (15) remains in pressure contact with the projecting piece (10) and does not oscillate.

Then, since the first magnet (26) is slightly separated from the first switch (28) which has been close to that time, the proximity switch constituted by both of them operates to immediately turn on the air cylinder (25). Shorten and the traveling arm (31) is pulled outward along the guide rail (17).

As shown in FIG. 6, when the third magnet (37) comes close to the third switch (38), the proximity switch made up by both of them actuates to stop the traveling and the injection pipe ( 31) retracts to the outside of the wheel (5).

In this state, while the nozzle (36) cleans the outer surface of the wheel (5) and the inside of the tire house (6) and further advances to pass the front end of the wheel (5), the leg ( A photoelectric detection device (not shown) provided in 3) detects this, and immediately activates the rotating prime mover (80) to extend the lower link (25).

As a result, as shown in FIG. 1, the nozzle (36) at the tip re-enters the lower part of the vehicle (4), and all the nozzles (36) (36) cause the lower surface and the lower part of the side surface of the vehicle (4). And are washed. The traveling arm (31) operates around the front wheel (5) in the same manner as described above to wash the outer surface of the wheel (5) and the tire house (6), and then the lower surface of the vehicle (4). Clean the bottom of the sides.

As shown in FIG. 6, while the traveling arm (31) passes the outside of the wheel (5), the high-pressure water is blocked by the wheel (5), and moves inward from the wheel (5). It is never jetted. However, as shown in FIG. 5, since the two nozzles (36) at the inner end of the traveling arm (31) are inclined forward, rearward, and inward, the traveling arm (31) is retracted. Even if it comes to the front and rear of the wheel (5), the peripheral surface of the wheel (5) and the lower surface of the vehicle (4) inside thereof will be washed.

Further, by setting the angle of the nozzle (36) at the inner end as required, the inner side surface of the wheel (5) can be cleaned when the traveling arm (31) extends. The second switch (29) is actuated by the proximity of the first magnet (26) or the second magnet (27) when the traveling arm (31) swings abnormally for some reason, and thus the gate type car wash machine. Immediately stop running and jetting of high-pressure water.

It goes without saying that the vehicle position detecting device using the proximity switch may be replaced by a photoelectric tube type, an ultrasonic wave reflecting type, or a micro switch actuating type using a mechanical feeler.
