[0009] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail.

[0010] <Overview of cleaning equipment> In this embodiment, a washing device 100 for washing a vehicle 1 will be described with reference to Fig. 1 to Fig. 4. Fig. 1 is a schematic side view of the washing device 100. Fig. 2 is a perspective view of the washing device 100 shown in Fig. 1, seen from the front. Fig. 3 is a perspective view of the washing device 100 shown in Fig. 1, seen from the rear. Fig. 4 is an enlarged view of a portion surrounded by dashed line A shown in Fig. 2.

[0011] For ease of explanation, the up-down direction, the front-rear direction, and the left-right direction are defined as shown by the arrows in Fig. 1 etc. The front direction is the direction in which the vehicle 1 to be washed is parked relative to the washing device 100. The front-rear direction is the vehicle length direction of the vehicle 1, the left-right direction is the vehicle width direction of the vehicle 1, and the up-down direction is the vehicle height direction of the vehicle 1. Note that in this embodiment, the up-down direction is a direction perpendicular to the front-rear direction and the left-right direction, and the front-rear direction is a direction perpendicular to the left-right direction.

[0012] (vehicle) As shown in Fig. 1, vehicle 1 is a compactor vehicle, and has a hopper 2 located at the rear of vehicle 1, and a garbage storage chamber 3 that stores garbage and the like thrown in through an inlet of the hopper 2. The hopper 2 is connected to the garbage storage chamber 3 so as to be movable between an open position 2A that opens an opening formed at the rear of the garbage storage chamber 3, and a closed position 2B that closes the opening at the rear of the garbage storage chamber 3. In Fig. 1, the hopper located in the open position 2A is shown by a solid line, and the hopper located in the closed position 2B is shown by a dashed line.

[0013] In this embodiment, an example is shown in which the vehicle 1 is a compactor vehicle, but the vehicle to be cleaned by the cleaning device 100 is not limited to a compactor vehicle and may be a truck, etc. The cleaning device 100 of the present disclosure is suitably used for vehicles that require operation of the vehicle during cleaning, such as a vehicle that requires the back door to be opened to clean the inside.

[0014] (Cleaning Equipment) The washing device 100 washes the vehicle 1 located in front of the washing device 100. The washing device 100 performs washing in various modes based on the operation of an operation panel (not shown). As shown in Fig. 2, the washing device 100 is a U-shaped washing device when viewed from the front-rear direction. The washing device 100 includes a support 10, a washing unit 20, and a guard member 30.

[0015] A pair of pillars 10 are provided, and stand on both sides in the width direction of the vehicle 1. The height of the pillars 10 in the vertical direction is approximately the same as the vehicle height of the vehicle 1. The height of the pillars 10 may be lower than the vehicle height of the vehicle 1 or may be higher than the vehicle height of the vehicle 1. The height of the pillars 10 is lower than the position of the hopper 2 located in the open position 2A. As shown in FIG. 3, the lower parts of the pair of pillars 10 may be connected by a connecting wall 15. As shown in FIG. 2, the pair of pillars 10 support the washing unit 20. That is, the pillars 10 stand on both left and right sides of the washing unit 20 described later.

[0016] The cleaning unit 20 is a unit that sprays cleaning liquid onto the vehicle 1 to be cleaned. The width direction of the cleaning unit 20 corresponds to the left-right direction. The cleaning unit 20 can be raised and lowered in the up-down direction relative to the pair of support columns 10. The cleaning unit 20 may have multiple nozzles (not shown). Cleaning liquid is sprayed from each nozzle to clean the vehicle 1. The multiple nozzles of the cleaning unit 20 are arranged at a distance from each other in the left-right direction. Each nozzle is covered by a cover 21, and sprays cleaning liquid toward the vehicle 1 from an opening 22 formed in the cover 21.

[0017] The cleaning unit 20 may be tiltable forward or backward with respect to the support 10. When the cleaning unit 20 tilts forward, the cleaning liquid can be sprayed from each nozzle in a forward and downward direction. When the cleaning unit 20 tilts backward, the cleaning liquid can be sprayed from each nozzle in a forward and upward direction. In addition, each of the nozzles of the cleaning unit 20 may be swivellable in the left-right direction.

[0018] The guard member 30 is a member that protects the washing unit 20 and / or the support pillar 10. The guard member 30 reduces the possibility that the hopper 2 of the vehicle 1 contacts the washing unit 20 and / or the support pillar 10, for example. The guard member 30 may be a transport jig when transporting the washing device 100. The guard member 30 may be, for example, a prismatic pipe made of steel. By using a prismatic pipe as the guard member 30, the manufacturing cost can be reduced. Note that the guard member 30 is not limited to a prismatic pipe made of steel. The guard member 30 may be a cylindrical pipe. The guard member 30 is not limited to a pipe, and may be a solid member or a plate-shaped member. The guard member 30 may be a member having a cross section in a C-shape, H-shape, L-shape, or the like.

[0019] The guard member 30 is supported on the upper part of the support pillars 10, straddling the two support pillars 10. The guard member 30 may be disposed on the upper part of the pair of support pillars 10, on the side closer to the vehicle 1. That is, the guard member 30 may be disposed on the front side of the upper part of the pair of support pillars 10. More specifically, the guard member 30 may be disposed so that the front surface of the guard member 30 and the front surface of the support pillar 10 are substantially at the same position in the front-rear direction. It is preferable that the guard member 30 is disposed on the front side of the upper part of the pair of support pillars 10, but it may be disposed in the center part or on the rear side in the front-rear direction. The guard member 30 may be supported on the support pillar 10 so that the front surface of the guard member 30 is located forward of the front surface of the support pillar 10. In this embodiment, the guard member 30 is one, but the present invention is not limited to such a configuration. A plurality of guard members 30 may be supported on the upper part of the support pillar 10.

[0020] Moreover, the guard member 30 may be decorated to draw the attention of the driver of the vehicle 1. The decoration for drawing attention is a decoration that makes it easier for the driver to recognize the presence of the guard member 30 when reversing the vehicle 1. One example of the decoration for drawing attention is a traffic light tape.

[0021] As shown in FIG. 4, the guard member 30 may be fixed to each support 10 by a mounting bracket 40. The mounting bracket 40 is an example of a mounting bracket. The mounting bracket 40 may be fixed to the guard member 30 and the support 10 by, for example, bolt fastening. The mounting bracket 40 is a metal mounting bracket and has, for example, an L-shape. The mounting bracket 40 has a standing wall portion 41 and a protruding wall portion 42. The standing wall portion 41 is a main portion of the mounting bracket 40 and is a wall portion that extends in the up-down direction when attached to the support 10. The standing wall portion 41 is connected to the guard member 30 above the standing wall portion 41 and is connected to the support 10 below the standing wall portion 41. The protruding wall portion 42 is a wall portion that protrudes in the front-rear direction from the standing wall portion 41. More specifically, the protruding wall portion 42 protrudes rearward below the standing wall portion 41. The mounting bracket 40 may have a hanging hole 43 to which a hanging tool used when transporting the cleaning apparatus 100 can be hung. The hanging hole 43 may be formed in the protruding wall portion 42. The hanging hole 43 is a hole to which a hanging tool such as a chain hook can be hung when the cleaning apparatus 100 is transported.

[0022] The guard members 30 may be disposed at a vertical interval S with respect to each of the posts 10. More specifically, the vertical interval S is the interval between the lower end of the guard member 30 and the upper surface of the post 10. The vertical interval S may be 50 mm or more and 500 mm or less, for example, about 200 mm.

[0023] A connecting bar 50 may be disposed on the upper part of the pair of support columns 10. The connecting bar 50 is a member for preventing the support columns 10 from bending inward and causing deformation of the cleaning unit 20. The connecting bar 50 straddles the support columns 10 and is supported on the upper part of the support columns 10. The connecting bar 50 is disposed on the upper part of the pair of support columns 10 on the side farther from the vehicle 1. That is, the guard member 30 may be disposed on the rear side of the upper part of the pair of support columns 10. The connecting bar 50 may be disposed without any gap between each of the support columns 10 in the up-down direction. The connecting bar 50 is a member having an L-shaped cross section. The connecting bar 50 is not limited to a member having an L-shaped cross section, and may be a member having a cross section of a shape other than an L-shape, or may be a pipe-shaped member.

[0024] <Vehicle washing process> The following describes an exemplary flow of washing the vehicle 1 by the washing device 100. In the following description, the driver of the vehicle 1 will be simply referred to as the driver.

[0025] First, the outer surface of the hopper 2 of the vehicle 1 is washed. The driver stops the vehicle 1 in front of the washing device 100 so that the hopper 2 of the vehicle 1 and the washing device 100 face each other. The driver operates the vehicle 1 so that the hopper 2 is located in the closed position 2B. After that, the washing device 100 starts washing the outer surface of the hopper 2.

[0026] The cleaning device 100 sprays cleaning liquid from the nozzle of the cleaning unit 20 and cleans the outer surface of the hopper 2 while swinging the nozzle of the cleaning unit 20. The cleaning device 100 cleans the outer surface of the hopper 2 while moving the cleaning unit 20 back and forth in the up and down direction relative to the support 10. The cleaning device 100 also cleans the outer surface of the hopper 2 while tilting the cleaning unit 20 forward or backward relative to the support 10.

[0027] Next, the inner surface of the hopper 2 blocking the rear opening of the waste storage chamber 3 and the interior of the waste storage chamber 3 are cleaned. When the hopper 2 is in the open position 2A, the inner surface of the hopper 2 and the interior of the waste storage chamber 3 can be cleaned by the cleaning device 100. The driver operates the vehicle 1 so that the hopper 2 is in the open position 2A. If the vehicle 1 is a rotary compactor vehicle, the driver may perform an operation to dump the waste storage chamber 3 to a predetermined angle. Thereafter, the cleaning device 100 cleans the inner surface of the hopper 2 and the interior of the waste storage chamber 3.

[0028] The cleaning device 100 first cleans the inner surface of the hopper 2. The cleaning device 100 cleans the inner surface of the hopper 2 while swinging the nozzle of the cleaning unit 20. The cleaning device 100 also cleans the inner surface of the hopper 2 while moving the cleaning unit 20 back and forth in the vertical direction relative to the support 10. The cleaning device 100 tilts the cleaning unit 20 backward relative to the support 10. This allows the cleaning liquid sprayed from the nozzle of the cleaning unit 20 to be sprayed upward from below, making it possible to clean the inner surface of the hopper 2 located in the open position 2A. When cleaning the inner surface of the hopper 2, the subsequent angle of the cleaning unit 20 relative to the support 10 may be changed.

[0029] After the inner surface of the hopper 2 is cleaned, the interior of the garbage storage chamber 3 is cleaned. The cleaning device 100 cleans the interior of the garbage storage chamber 3 while swinging the nozzle of the cleaning unit 20. The cleaning device 100 also cleans the interior of the garbage storage chamber 3 while moving the cleaning unit 20 back and forth in the vertical direction relative to the support 10. The cleaning device 100 also cleans the interior of the garbage storage chamber 3 while tilting the cleaning unit 20 forward or backward relative to the support 10. For example, in the case of a rotary packer vehicle, the garbage storage chamber 3 may be dumped significantly in order to discharge the cleaning liquid accumulated inside the garbage storage chamber 3 to the outside.

[0030] An operator of the cleaning device 100 operates the operation panel to select a desired cleaning mode and press the cleaning start button. The cleaning device 100 sprays cleaning liquid from each nozzle of the cleaning unit 20 and starts cleaning the vehicle 1. When cleaning the vehicle 1, the support 10 does not move in the forward or backward direction. While cleaning the vehicle 1, the cleaning unit 20 moves in the vertical direction relative to the support 10 according to the selected cleaning mode, and sprays cleaning liquid onto the vehicle 1 while leaning forward or backward relative to the support 10. This cleans the hopper 2 and / or the interior of the waste storage chamber 3 of the vehicle 1.

[0031] When washing the vehicle 1, the vehicle 1 is operated by a driver. Therefore, it is possible that the hopper 2 of the vehicle 1 may come into contact with the support 10 and / or the washing unit 20 of the washing device 100 due to an erroneous operation by the driver of the vehicle 1. Possible erroneous operations by the driver include (i) moving the hopper 2 from the open position 2A to the closed position 2B while the support 10 or the washing unit 20 is located within the movement trajectory of the hopper 2, and (ii) in a rotary packer vehicle, dumping the waste storage chamber 3 by more than a predetermined angle while the hopper 2 is located in the open position 2A.

[0032] The cleaning device 100 has a guard member 30 arranged on the upper part of a pair of pillars 10. Therefore, even if the hopper 2 of the vehicle 1 comes into contact with the cleaning device 100 from above, the impact is absorbed by the guard member 30, thereby reducing damage to the pillars 10 and the cleaning unit 20.

[0033] In addition, the guard member 30, which is arranged to straddle a pair of pillars 10, also functions as a transport jig, eliminating the need for a dedicated transport jig, eliminating the need to attach and detach the dedicated transport jig, and also eliminating the need to transport the removed jig.

[0034] In addition, since there is a vertical gap S between the guard member 30 and the pair of pillars 10, when various parts of the vehicle 1 come into contact with the guard member 30 and the guard member 30 is deformed, the direct transmission of impact to each pillar 10 can be prevented.

[0035] Moreover, the mounting bracket 40 has a lifting hole 43. Therefore, when the cleaning device 100 is transported while being lifted by a crane or the like, the cleaning device 100 can be stably lifted by hanging a lifting tool (such as a chain hook) on the lifting hole 43 of the mounting bracket 40.

[0036] In addition, the guard member 30 is disposed on the side closer to the vehicle 1 with which each part of the vehicle 1 (such as the hopper 2) is likely to come into contact. This effectively reduces the possibility that the hopper 2 and the like will come into direct contact with each support 10 and the washing unit 20.

[0037] 〔summary〕 The cleaning device according to aspect 1 of the present disclosure comprises a cleaning unit that sprays cleaning liquid onto a vehicle to be cleaned, a pair of support pillars erected on both sides of the width of the cleaning unit and supporting the cleaning unit, and a guard member that protects the cleaning unit and / or the support pillars, the guard member spanning between the support pillars and supported on the upper parts of the support pillars.

[0038] According to the cleaning device of aspect 1, a guard member is disposed on the upper part of a pair of support pillars. Therefore, even if parts of a vehicle come into contact with the cleaning device from above, the guard member absorbs the impact, thereby reducing damage to the support pillars and cleaning unit.

[0039] In addition, since the guard member, which is positioned across a pair of supports, also functions as a transport jig, a dedicated transport jig is not required, which eliminates the need to attach and detach a dedicated transport jig, as well as the labor required to transport the removed jig.

[0040] In a cleaning device according to aspect 2 of the present disclosure, in the above aspect 1, the guard members are disposed at intervals in the up-down direction relative to the respective support pillars. According to the cleaning device according to aspect 2, since there is an interval in the up-down direction between the guard members and the pair of support pillars, when the guard members are deformed due to contact with various parts of the vehicle, it is possible to prevent an impact from being directly transmitted to the support pillars.

[0041] In the cleaning device according to aspect 3 of the present disclosure, in the above aspect 1 or 2, the guard members are fixed to the respective supports by mounting brackets, and the mounting brackets have a hanging hole to which a hanging tool used for transporting the cleaning device can be hung. According to the cleaning device according to aspect 3, when the cleaning device is transported while being hoisted by a crane or the like, the cleaning device can be stably lifted by hanging the hanging tool in the hanging hole of the mounting bracket.

[0042] In a cleaning device according to aspect 4 of the present disclosure, in any one of aspects 1 to 3 above, the guard member is disposed on the upper portion of the pair of support pillars, on the side closer to the vehicle. According to the cleaning device according to aspect 4, the guard member is disposed on the side closer to the vehicle, with which each part of the vehicle is likely to come into contact. This makes it possible to effectively prevent a hopper or the like from directly contacting each support pillar and the cleaning unit.

[0043] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
