  As described in Patent Document 1, the method of simply suspending the cleaning water supply pipe obstructs the operator when manually performing brushing work or wiping work on the surface of the automobile after the cleaning water is jetted. In addition, since the washing water supply pipe must have sufficient flexibility, the durability is poor. In addition, as described in Patent Documents 2 and 3, in the method of using the pipe support guide means having a dedicated bent link structure for supporting the cleaning water supply pipe, there is a problem when the cleaning water supply pipe is simply suspended. However, the pipe support guide means having the bent link structure requires a certain height (thickness) in the link member in order to prevent downward bending deformation. In the configuration in which the piping support guide means bends and moves on the upper side of the portal traveling body, the height of the space required on the upper side of the portal traveling body is relatively large, and not only the height of the entire apparatus is increased, It becomes impossible to attach the support structure including the guide rail of the portal running body directly to the ceiling surface of the building.

  Further, in the configuration described in Patent Document 3, the traveling main body portion that is sufficiently narrower than the lateral width at the positions of the left and right vertical column portions of the portal-shaped traveling body and that is supported and guided by the guide rail so as to travel freely is portal-shaped traveling. Since the pipe support guide means must be connected to the side of this traveling main body part, it must be connected to the side of this traveling body part, so the distance between the pair of left and right guide rails that support the gate-shaped traveling body can be moved back and forth. It becomes narrow and is inferior in terms of running stability of the portal-type traveling body and support strength of the entire portal-shaped traveling body.

An object of the present invention is to solve the above-described conventional problems. In the invention described in claim 1, reference numerals of embodiments to be described later are shown in parentheses.

In the car wash machine in which washing water is jetted into the space surrounded by the gate-shaped traveling body (4), the horizontal body (5) of the portal-shaped traveling body (4) has an intermediate from one end thereof. A horizontal recessed space (41) penetrating in the front-rear direction, which reaches an appropriate position and is opened at one end of the horizontal main body (5), is formed, and the portal traveling body (4) and the supporting structure (1) In between In addition, a pipe support guide means (43) for supporting the cleaning water supply pipe (42a) is provided, and the pipe support guide means (43) is provided with a vertical support shaft so that the intermediate position is always bent horizontally on the same side. 47), which is composed of at least two link members (48, 49) connected to each other , and the end on the side of the portal-type traveling body (4) is a vertical support shaft in the horizontal recessed space (41). is supported by (51) Rutotomoni, end of the supporting structure (1) side, of the side portions of the supporting structure (1), the open end of the horizontal concave space (41) The pipe support guide means (43) is supported by the vertical support shaft (50) on the adjacent side portion, and the open end of the horizontal recessed space (41) as the portal-type traveling body (4) travels. Of the supporting wheels (33a to 34b) supported by both ends of the horizontal main body (5) of the portal-type traveling body (4). The support wheels (33a, 34a) on the open end side of the space (41) A pipe (7) that is pivotally supported by the end of the horizontal main body (5) on the upper side of the space (41) and that is connected to the side washing water spray nozzle (8, 9) on the open end side of the horizontal recessed space (41). ) Is arranged in the horizontal main body (5) below the horizontal recessed space (41).

  When the above-mentioned present invention is carried out, specifically, as described in claim 2, the link member (48, 49) of the pipe support guide means (43) is connected to each link member (48, 49). The wash water supply pipe (42a) is held in the groove steel constituting each link member (48, 49) and washed water. The portion of the supply pipe (42a) that is detoured outwardly between the link members (48, 49) is supported by the pipe support guide means (43) and horizontally between the link members (48, 49). It can be supported by the protruding pipe support (53).

  According to a third aspect of the present invention, the support structure (1) includes support wheels (33a to 34b) pivotally supported at both ends of the horizontal body (5) of the portal-type traveling body (4). A pair of left and right guide rails (2a, 2b) that support the gate-shaped traveling body (4) so as to be able to reciprocate back and forth through a pair, and a pair of front and rear links that connect the ends of the guide rails (2a, 2b) The frame material (3a, 3b) is configured in a rectangular frame shape, and the end of the pipe support guide means (43) on the support structure (1) side is below the guide rail (2a) on one side. The washing water supply pipe (42a) is supported on the vertical support shaft (50) and below the guide rail (2a) below the region where the pipe support guide means (43) does not enter. A supporting pipe support member (44) can be attached. In this case, as described in claim 4, the guide rail (2a) is constituted by connecting a plurality of guide rails (14) by connecting means (15), and the lower side of the guide rail (2a). The vertical support shaft (50) that pivotally supports the end of the pipe support guide means (43) is attached not to the guide rail alone (14) but to the connecting member (20) constituting the connection means (15). Can do.

  In addition, as described in claim 5, of the cleaning water spray nozzles (8, 9), at least the upper cleaning water spray nozzle attached to the lower side of the horizontal main body (5) of the portal-type traveling body (4). (8) is a rotating nozzle that rotates around a vertical axis (8a) by water pressure, and a nozzle base (8e, 8f) located laterally away from the vertical axis (8a), A configuration may be adopted in which cleaning water is jetted obliquely outward and downward away from the vertical axis (8a).

  Furthermore, as described in claim 6, in the horizontal main body (5) of the portal-type traveling body (4), support wheels (33a to 34b) pivotally supported at both ends of the horizontal main body (5) are provided. A transmission shaft (37a, 37b) that interlocks the two is supported above the horizontal recessed space (41), and the support wheels (33a-34b) are driven to rotate through the transmission shaft (37a, 37b). The motor (39) can be supported in an area where the horizontal recessed space (41) is not provided in the horizontal main body (5) of the portal-type traveling body (4).

  According to the configuration of the present invention as set forth in claim 1, the pipe support guide means for supporting the cleaning water supply pipe spanned between the portal traveling body and the supporting structure, that is, the intermediate position is always on the same side. The pipe support guide means composed of at least two link members connected to each other by the vertical support shaft so as to be bent horizontally is not the upper side or the side part of the portal type traveling body, but the horizontal direction of the portal type traveling body. Since it is pivotally supported in a horizontal recessed space formed from one end of the horizontal main body within the thickness range of the main body, it is necessary to secure a space in which the pipe support guide means bends and moves above the portal type traveling body. Therefore, the height of the entire apparatus can be reduced, and the supporting structure can be directly attached to the lower surface of the ceiling of the building. Of the supporting wheels pivotally supported at both ends of the horizontal body of the portal-type traveling body, the supporting wheel on the open end side of the horizontal recessed space is the end of the horizontal body above the horizontal recessed space. Therefore, the distance between the pair of left and right guide rails required to support the portal traveling body so as to be movable back and forth is almost the same as the lateral width of the entire portal traveling body including the left and right vertical pillars. It can be made wider or wider, and the running stability of the portal traveling body and the support strength of the entire portal traveling body can be increased.

  In addition, according to the structure of Claim 2, the wash water supply pipe supported by the pipe support guide means can be protected in the link member (the grooved steel opened horizontally horizontally), and each of the wash water supply pipes Portion-type traveling bodies and supporting structures can be supported by piping support parts that are diverted to the outside between the link members, that is, portions that are expected to sag because they cannot be supported in the link members. It is possible to suppress deterioration of the cleaning water supply pipe that extends between the two and the risk of damage.

  According to the configuration of claim 3, the pair of left and right guide rails for supporting the portal traveling body so as to be movable back and forth also serve as the frame material of the supporting structure, and at the same time for supporting the pipe support guide means. Since it also serves as a support member on the structure side, the structure of the support structure is simplified and can be implemented at low cost. Further, since the cleaning water supply pipe supported by the pipe support guide means can be supported along the guide rail by the pipe support member on the lower side of the guide rail, for example, the corner portion of the support structure (the guide rail Even when the supporting structure is self-supported by the support member supporting the end portion, it is convenient to finally guide the cleaning water supply pipe to the floor surface using the support member. In this case, according to the configuration described in claim 4, the connecting member of the connecting means for connecting the guide rails to each other, and the connecting member that is usually made of a thicker plate than the guide rail, Since the vertical support shaft that pivotally supports the end portion of the pipe support guide means is attached, there is no fear of reducing the strength of the guide rail, and the support strength of the end portion of the pipe support guide means can be increased.

  Further, according to the configuration of claim 5, the upper washing water attached to the lower side of the horizontal main body of the portal-type traveling body only by traveling the portal-shaped traveling body to a position slightly over the front and rear end faces of the automobile. Both the front and rear end faces of the automobile can be reliably cleaned by the swirling flow of cleaning water that spreads toward the lower side generated from the injection nozzle, that is, the rotating nozzle. In addition, since it automatically turns with water pressure, the entire system can be implemented at a lower cost compared to a configuration in which the cleaning water injection nozzle is forcibly rotated by an actuator such as a motor, and the rear of the vehicle body that injects cleaning water diagonally forward and downward. Compared with the case where the end surface cleaning nozzle and the front end surface cleaning nozzle for injecting the cleaning water obliquely downward are provided, the piping structure of the cleaning water supply pipe in the portal traveling body is simplified.

  Furthermore, according to the structure of Claim 6, although it is a portal-type traveling body in which a horizontal recessed space is formed in the horizontal main body, both ends of the horizontal main body are driven by motors installed in the horizontal main body. Both of the supporting wheels that are pivotally supported by the motor can be synchronously driven to be driven forcibly, and a self-propelled portal-type traveling body that can smoothly and straightly travel can be obtained.
