  However, in the conventional car wash work by human power, the leading car is large, especially the front shape is complicated and the area is large, so the worker should support the long handle with the wash brush attached to the tip with both hands. This work requires skill and great effort. In addition, a vehicle body cleaning device that provides a cleaning brush on a rotating body with rotating blades and performs cleaning while automatically rotating the cleaning brush by applying cleaning liquid to the rotating blades can improve the efficiency of the cleaning operation, but the weight of the tip of the handle is low. Due to the large size, a great amount of labor is required for the vehicle body cleaning work, and the worker's fatigue is extremely increased.

  The vehicle body washing apparatus according to the present invention solves such a conventional problem, so that the operation of the long tube, which is a handle having a washing brush at the tip, can be easily performed without requiring skill, An object of the present invention is to enable efficient cleaning of the front surface of the leading vehicle.

In order to achieve the above object, a vehicle body washing apparatus according to the present invention includes a carriage that can run on a running rail of a vehicle, a rod that is driven up and down along a column that is erected on the carriage, and the rod.

A long pipe for water supply, and the direction of the cleaning brush can be changed in the vertical and horizontal directions at the tip of the crane member, and by the horizontal rotation of the crane member and the horizontal link and the vertical movement of the rod The above Characterized in that the freely movable position of Kiyoshi brush to vertical and horizontal and in the longitudinal direction.

As a result, the carriage is moved onto the running rail of the railway vehicle and stopped at a predetermined position in front of the leading vehicle (paragraph number 0024), and when the operator operates the long tube with one hand or both hands (paragraph number 0026), Since the long pipe including the cleaning brush is supported by the crane member, the entire weight including the long pipe and the brush main body is supported by the crane member, and the movement and direction change of the cleaning brush by the operation of the long pipe are light and easy. It can be done quickly (paragraph numbers 0026 and 0027).
Further, since the long pipe is supported by a rod that can be moved up and down via a crane member and two universal joints, the movement of the long pipe can be freely moved within a sufficiently large stroke region (paragraph). Number 0028). As a result, the entire front surface of the leading vehicle having a large washing target such as a Shinkansen vehicle can be sufficiently washed without moving the vehicle or the rod.

Further, the vehicle body cleaning apparatus of the present invention is characterized in that the cleaning brush has a nozzle mounting housing attached to the end of the long tube, and a shaft attached to the nozzle mounting housing so as to penetrate inside and outside of the nozzle mounting housing. A tube, a plurality of injection nozzles attached to the tip of the shaft tube so as to face outward, a disk-shaped brush holding member rotatably supported around the shaft tube, and the brush holding plate A plurality of rotating propellers that receive the spray water sprayed from the spray nozzle and apply a rotational force to the brush holding member, and a brush body attached to the periphery of the brush holding member. characterized in that it comprises Te.

On the other hand, the other end of the rubber hose 21 is connected to the long tube 13 over a predetermined length. It is desirable that the rubber hose 21 has good water pressure resistance and is as soft and flexible as possible.

  FIG. 3 is a cross-sectional view showing details of the cleaning brush 16. In FIG. 3, the distal end of the long tube 13 is fixed to one side portion of the nozzle attachment housing 22, and the shaft tube 23 is attached to the other side portion of the nozzle attachment housing 22. The end of the shaft tube 23 in the nozzle mounting housing 22 is open in the direction of the long tube 13. The cleaning brush 16 has an outer diameter of 300 to 200 mm, preferably 250 mm, and an inner diameter of 180 to 220 mm, preferably about 210 mm in order to efficiently perform the cleaning operation. Is preferred.

  On the other hand, a boss portion 27 of the rotating body 26 is rotatably supported via a bearing 25 at a portion of the shaft cylinder 23 that protrudes outside the nozzle mounting housing 22. The rotating body 26 has a ring-shaped brush holding plate 28 at the tip, and two large and small cylindrical plates 28 b and 28 c are attached to the periphery of the brush holding plate 28. A short cylindrical brush body 29 having a certain thickness is detachably fixed between the cylindrical plates 28b and 28c by a fastening member 30 such as a bolt and a nut. The brush body 29 is made of animal or synthetic resin brush, sponge, woven fabric, or a mixture thereof, and is made of a member having a hardness that does not damage the surface of the vehicle. Here, the length of the brush of the brush body 29 is about 80 to 150 mm, and preferably about 100 mm. The thickness is preferably in the range of about 15 to 40 mm and around 25 mm.

  As shown in the drawing, the distal end portion of the shaft cylinder 23 is an enlarged diameter portion 31, and the enlarged diameter portion 31 faces the ring hole 28 a of the brush holding plate 28 without interfering with it. A plurality of cleaning liquid passage holes 32 are formed in the enlarged diameter portion 31 so as to face in the radial direction, and ends of the respective cleaning liquid passage holes 32 are closed by plugs 33. These cleaning liquid passage holes 32 communicate with the cylindrical hole 34 of the shaft cylinder 23 and the long pipe 13.

  Further, as shown in FIG. 4, a plurality of, for example, about 3 to 6, nozzle nozzles 35 are attached to the enlarged diameter portion 31 in the present invention. These spray nozzles 35 communicate with the respective cleaning liquid passages 32 and are fixed obliquely with respect to the end surface (vertical surface) of the enlarged diameter portion 31. Further, the nozzle ends 35 a of these injection nozzles 35 are directed to a plurality of L-shaped rotary propellers 28 a attached to the brush holding plate 28 as shown in the figure. Accordingly, the cleaning liquid sprayed from the end of the spray nozzle 35 is applied obliquely to the inner surface of the rotary propeller 28a, and the spray pressure is sequentially received by the rotary propellers 28a so that the brush holding plate 28 receives a rotational force in a certain direction. Functions to grant. For this reason, the rotating body 26 provided with the brush body 29 rotates around the shaft cylinder 23. The long tube 13, the nozzle mounting housing 22, the boss portion 27 of the rotating body 26 and the brush holding plate 28 are made of a lightweight metal material, for example, aluminum, and are used when operating the cleaning brush 16 manually. To reduce the burden.

Next, the operation of the vehicle body washing apparatus having the above configuration will be described.
When the front surface of the top car is cleaned by the vehicle body cleaning device, first, the wheel 2 of the carriage 3 is run along the traveling rail 1 and the carriage 3 is stopped at a predetermined position in front of the top car. Subsequently, the water pump 17 is driven, and the cleaning water stored in the water storage tank T is sucked up by the water absorption pipe 18 through the filter 20. The washing water sucked up in this way is further fed into the cylindrical hole 34 of the shaft cylinder 23 through the water supply pipe 19, the rubber hose 21 and the long pipe 16, and is divided into a plurality of cleaning liquid through holes 32 from here.

  The cleaning liquid divided into the cleaning liquid passages 32 passes through the injection nozzles 35 and is jetted toward the inner peripheral surface of the rotary propellers 24 in a high pressure state as illustrated. For this reason, each rotary propeller 24 receives the injection pressure of the cleaning liquid in the rotation direction, and rotates around the shaft cylinder 23 together with the rotating body 26. Further, the cleaning liquid sprayed from each spray nozzle 35 sufficiently wets the brush body 29 directly or indirectly via the rotating propeller 24, and a part of the cleaning liquid is retained.

  Therefore, the cleaning operator grips the base end portion (lower part in the figure) of the long tube 13 with one hand or both hands, and the cleaning brush 16 supported at the tip of the long tube 13 is the target portion on the front surface of the leading vehicle. The long tube 13 is operated so as to be positioned in the position. At this time, since most of the weights of the long tube 13 and the cleaning brush 16 are supported by the long tube holding member 14 at the lower end portion of the crane member 11, the operation does not require a large amount of labor. It can be done lightly.

  On the other hand, since the front face of the leading car has a complex uneven surface, the brush body 29 is moved to the front face of the leading car by rotating the long pipe 13 around the central axis in the long pipe holding member 14. The direction can be changed from left to right. Further, by operating the long tube 13 so that the long tube holding member 14 rotates about the horizontal axis 15 with respect to the mounting member 12, the direction of the brush body 29 can be changed in the vertical direction. Each of these operations is easily performed with the assistance of the crane member 11 with respect to the long tube 13.

  Further, the base end (upper end) of the crane member 11 is horizontally rotatable by the universal joint portion 10, and the brush body 29 can be moved in the left-right direction within a large range with respect to the front surface of the leading car. . Further, the joint 10 portion is supported by horizontal links 7 and 8 that rotate in the vertical direction by a universal joint 9. As a result, the brush body 29 can move in the vertical direction together with the crane member 11. Further, the rod 6 to which the universal joint portion 9 is attached is movable up and down and horizontally rotatable with respect to the column 5. As a result, the brush body 29 can move up and down with a sufficient stroke together with the crane member 11 and the horizontal links 7 and 8.

  As a result, the portion of the crane member 11 to which the cleaning brush 16 is attached can freely move within a region H indicated by hatching in FIG. 1, and the brush body 29 is desired over a wide region in front of the leading car. Can be contacted in the direction of. As a result, complicated shapes and uneven surfaces can be thoroughly cleaned.

  The present invention is to rotate the cleaning brush attached to the tip of the long tube and operate the long tube to clean the front part of the vehicle, not only cleaning the front of the front car, It can also be used to clean the side of the vehicle.
