In the first aspect of the invention, since the end of the pedal on the front side in the passing direction of the vehicle is pivotally supported to allow the pedal to rotate freely, the pedal will rotate so as to approach the vehicle when the vehicle passes. Therefore, the rotation speed of the pedal is high, and the hydraulic pressure of the liquid injected to the tire can be made strong.

In the second aspect of the invention, the flexible member protrudes farther than the end of the pedal on the rear side in the passing direction of the vehicle. Therefore, when sand and gravel move from the upper surface of the pedal to the rear of the pedal, the gravel and the like will not be sandwiched between the wall of the working room and the pedal, but between the wall of the working room and the flexible Between parts. In this way, gravel and the like are sandwiched between the pedal which is a rigid member and the working chamber, and it is possible to prevent the rotation of the pedal from being hindered.

In the third aspect of the invention, the flexible member is provided on the lower surface of the pedal. Therefore, when the pedal rotates downward due to the weight of the vehicle, the flexible member is pressed by the pedal, and deformation is restricted. On the other hand, when the pedal is rotated upwards under the action of the urging member, the flexible member is deformed by the hydraulic pressure of the liquid in the working chamber, so the sand and gravel in the clamped state will not continue to hold In this state, it fell towards the bottom of the studio.

In the fourth aspect of the invention, the vehicle passing above the pedal presses the protrusion, which is formed on the forward side in the passing direction, that is, near the portion where the pedal is pivotally supported. Therefore, compared to the case where the vehicle is pressed to the end of the pedal on the rear side in the vehicle passing direction, the rotation speed of the pedal is faster.

In the fifth aspect of the invention, the injection pipe portion is provided separately from the pedal. Therefore, due to the rotation of the pedal, the outlet end of the injection pipe part will not be located below the liquid surface in the working chamber. In this way, it is possible to prevent the hydraulic pressure of the injected liquid from dropping by using the liquid in the working chamber.

In the sixth aspect of the invention, the cross-sectional area of the inlet end of the injection pipe portion is larger than the cross-sectional area of the outlet end. Therefore, it is possible to make the hydraulic pressure sprayed from the spray pipe portion stronger.

In the seventh aspect of the invention, the liquid ejected from the ejection tube portion is ejected in a plurality of directions. Therefore, a large area on the vehicle can be cleaned.

In the eighth aspect of the invention, the pumping device and the body frame are independent of each other. Therefore, when the pump device fails, the repair of the vehicle attachment removal device can be completed by only replacing the failed pump device.

In the ninth aspect of the invention, the injection hole is provided independently of the pedal. Therefore, due to the rotation of the pedal, the injection hole is not located on the lower side of the liquid surface in the working chamber. In this way, the liquid in the working chamber can be used to prevent the hydraulic pressure of the liquid ejected from the ejection hole from falling.

In the tenth aspect of the invention, attachments such as mud and sand removed from the vehicle body and attachments accumulated on the pedals can be discharged through the gap between the body frame and the pumping device. Therefore, it is possible to reduce the amount of deposits deposited on the pedal.

The following describes the embodiments of the present invention in detail based on the drawings. It should be noted that the embodiments and modification examples described below are only essentially preferable examples, and are not intended to limit the present invention, its application objects, or its scope of use.

－Integral structure－ As shown in Fig. 1 and Fig. 2, the tire cleaning device 1 has: a pair of left and right cleaning tanks 2, which are installed in the work place; and a first frame member 11, which is installed at the left and right ends of each cleaning tank 2 A plurality of second frame members 13 extend in the left-right direction between each pair of first frame members 11; the main body frame 15 has inclined portions 5, which are respectively formed in The front end and the rear end are inclined downward toward the middle portion in the front-rear direction; and a plurality of pumping devices 17 are respectively arranged between the second frame members 13 adjacent in the front-rear direction.

The first frame member 11 is made of channel steel and is arranged in the following manner: the web portion 11a (refer to FIG. 4) extends in the vertical direction, and the upper and lower flange portions 11b, 11c extend from both ends of the web portion 11a in the vertical direction Extend to the outside in the left and right direction. The first frame members 11 are provided at both ends in the left-right direction of each cleaning tank 2 and extend over the entire length of the cleaning tank 2. To the first frame member 11 on the right side of the washing tank 2 on the right side and the first frame member 11 on the left side of the washing tank 2 on the left side, fixing rods 18 extending in the front-rear direction are fastened with nuts and bolts. The fixing rod 18 positions a plurality of pumping devices 17 to a predetermined position of the cleaning tank 2.

The second frame member 13 is made of H-shaped steel and is arranged in the following manner: the web portion 13a (refer to FIG. 5) extends in the vertical direction, and the upper and lower flange portions 13b, 13c extend from both ends of the web portion 13a in the vertical direction Extend forward and backward. Between a pair of first frame members 11 corresponding to each cleaning tank 2, a plurality of second frame members 13 are arranged side by side at a predetermined pitch in the front-rear direction. The second frame member 13 is fixed to a pair of first frame members 11 corresponding to each cleaning tank 2 by welding at both ends in the left-right direction. At the rear of the upper flange portion 13b, a plurality of injection holes 13d are formed side by side in the left-right direction.

With regard to the tire cleaning device 1, when a vehicle passes through the cleaning tank 2, the left and right tires T of the vehicle will pass through the pumping device 17 arranged in the cleaning tank 2 respectively. In this way, the tire T of the vehicle is immersed in the washing liquid filled in the washing tank 2. In addition, a plurality of pumping devices 17 provided in the washing tank 2 are sequentially pressurized by the weight of the vehicle, and the pressurized pumping device 17 sequentially sprays the washing liquid in the washing tank 2 onto the tire T. In this way, the sludge and the like attached to the tire T are cleaned. However, instead of spraying only the tire T with the washing liquid, the washing liquid may be sprayed to both the periphery of the wheel including the tire T and the lower part of the vehicle body.

The installation place of each cleaning tank 2 is excavated in a work place such as civil engineering construction. A partition 3 is formed between the left and right washing tanks 2. A duct 19 connecting the left and right cleaning tanks 2 is provided in the partition 3. The deep-bottomed mud draining part 4 extends sideways and is formed in the front part of the washing tank 2 in the left-right direction. It should be noted that it is better to set the level WL of the cleaning liquid in the cleaning tank 2 to meet the following conditions: the level WL is always the same to ensure that when the vehicle passes through the cleaning tank 2, the lower end of the tire T of the vehicle Will be immersed in the cleaning fluid. However, when the tire T is cleaned, the cleaning fluid in the cleaning tank 2 will scatter outside the cleaning tank 2 or adhere to the tire T and be taken out of the cleaning tank 2, so the cleaning fluid will gradually decrease as the number of cleaning increases. Therefore, in order to keep the liquid level WL of the cleaning liquid at an appropriate level at all times, it is preferable to supply a necessary amount of cleaning liquid into the cleaning tank 2 by installing a float valve or the like. In addition, in order to prevent the washing liquid in the washing tank 2 from overflowing and polluting the surrounding environment when it rains, it is better to install a purification tank for purifying the remaining washing liquid.

The cleaning liquid filled in the cleaning tank 2 is suitable for tap water, but water from rivers, lakes, reservoirs, etc. can also be used. In addition, it is also preferable to add a cleaning agent to the water or use a disinfectant that disinfects avian influenza virus or the like.

－Pumping device- As shown in Figures 3 to 5, the pumping device 17 is a detachable pump unit housed in the main body frame 15. It has: a pivot 21, which is arranged in the corresponding cleaning tank 2 Between the upper part of the web portion 11a in the pair of first frame members 11; the pedal 23, the front end of which is pivotally supported by the pivot 21 to allow the pedal 23 to rotate freely; the working room 25, which is formed on the lower side of the pedal 23 , And used to contain the washing liquid; the coil spring 27, which acts as a urging member to urge the pedal 23 upward; the spray pipe part 29, which sprays the washing liquid to the vehicle; and the check valve 31.

The pumping devices 17 are respectively provided between the second frame members 13 adjacent in the front-rear direction and extend in the left-right direction. That is, in each washing tank 2, the second frame members 13 and the pumping device 17 are alternately arranged between the pair of first frame members 11 in the front-rear direction.

The front wall 33 constituting the front end of the pumping device 17 is provided such that its thickness direction coincides with the front-rear direction over the entire length of the pumping device 17 on the left and right. The lower end of the front wall 33 is in contact with the lower flange portion 13c of the second frame member 13 adjacent to the front, and the upper end of the front wall 33 is in contact with the upper flange portion 13b of the second frame member 13 adjacent to the front. A gap 33a is formed between the lower surfaces of the device. The front wall 33 is located on the rear side of the injection hole 13d of the second frame member 13. Therefore, the cleaning liquid in the working chamber 25 flows in front of the front wall 33 through the gap 33a. Then, the cleaning liquid is filled into the space 37 below the injection hole 13d. In addition, the extension 39 extending rearward from the lower end of the front wall 33 is formed by bending the lower end of the front wall 33. The extension portion 39 is carried by the upper surface of the flange portion 13c on the lower side of the second frame member 13 adjacent to the front.

The rear wall 41 constituting the wall surface on the rear side of the pumping device 17 is the wall surface of the working chamber 25 and is provided over the entire left and right lengths of the pumping device 17. The rear wall 41 bends toward the front as it is closer to the bottom, so that when the pedal 23 rotates, the rear wall 41 follows the path of the top end of the pedal 23 and forms a slight gap between the rear wall 41 and the pedal 23. The upper end of the rear wall 41 is designed to ensure that a gap in the front-rear direction is formed between the upper and lower flange portions 13 b and 13 c of the second frame member 13 adjacent to the rear, and the gap forms a discharge port 44. The attached matter such as mud and sand removed from the tire T and the attached matter accumulated on the pedal 23 fall to the bottom of the washing tank 2 through the discharge port 44 and are discharged out of the pumping device 17. It should be noted that the front wall 33 is carried by the flange 13c on the lower side of the second frame member 13 adjacent to the front, so that the pumping device 17 is positioned. The pumping device 17 and the first frame member 11 and The body frames 15 of the second frame member 13 are independent of each other.

At both ends in the left-right direction of the pumping device 17, side walls 43 whose thickness direction coincides with the left-right direction are formed. The side wall 43 is provided to face the web portion 11a of the first frame member 11, and a slight gap is left between the side wall portion 11a and the web portion 11a. The side wall 43 also protrudes further upward than the web portion 11a of the first frame member 11. As shown in FIG. 2, in a state where a plurality of pumping devices 17 are arranged in the front-rear direction, the convex portion 18a intermittently provided on the fixing rod 18 is sandwiched between the side walls 43 of the pumping devices 17 adjacent in the front-rear direction. between. In this way, the plural pumping devices 17 are positioned at predetermined positions in the front-rear direction of the cleaning tank 2.

As shown in FIGS. 3 to 5, in each side wall 43 at a height position corresponding to the pedal 23, a top plate portion 45 extending horizontally inward in the left-right direction is formed over the entire length of the pump device 17 in the front-rear direction. The top plate part 45 is fixed to the spray tube part 29 by welding. A fixed plate portion 47 extending vertically downward is formed at an end portion of the top plate portion 45 in the left-right direction. The pivot 21 is fixed to the fixed plate portion 47. A small gap is formed between the fixed plate portion 47 and the left and right end portions of the pedal 23.

The working chamber 25 is formed into a box shape opening upward by the top plate part 45, the front wall 33, the rear wall 41, the side wall 43, and the check valve 31, and the pedal 23 is provided to block the opening.

The pedal 23 is composed of a flat metal plate that is relatively slender in the left-right direction. That is, the pedal 23 is a rigid member. At the rear of the pedal 23, a plurality of convex portions 23a are formed at predetermined intervals in the left-right direction. The rear portion of the pedal 23 has a concave and convex shape in the front-rear direction due to the presence of the above-mentioned convex portion 23a. The pedal 23 constitutes the top surface of the working chamber 25. The pedal 23 is set to be able to rotate freely between the initial posture and the pressurizing posture. The initial posture is the approximately horizontal initial state of the pumping device 17 on the front side shown in FIG. The pumping device 17 is tilted with high front and low back.

As shown in FIGS. 3 to 5, on the upper surface of the pedal 23, a protrusion 49 is fixed by welding, and the protrusion 49 is composed of a metal rod extending in the left-right direction and protrudes upward. The protrusion 49 is provided at the front of the pedal 23, that is, near the pivot 21. The reinforcing rib 51 that connects the rear part of the protruding part 49 and the convex part 23 a of the pedal 23 is intermittently formed, for example, in four places on the upper surface of the pedal 23.

On the lower surface of the pedal 23, a flexible member 53 made of a flexible material such as rubber is provided. The flexible member 53 is formed in a rectangular plate shape. The flexible member 53 extends in the front-rear direction from a position slightly forward of the portion corresponding to the base end of the convex portion 23a to a position behind the top end of the convex portion 23a. That is, the flexible member 53 protrudes further to the rear side than the rear end of the pedal 23. The rear end of the flexible member 53 abuts on the rear wall 41. That is, the flexible member 53 is in sliding contact with the rear wall 41 when the pedal 23 is rotated. The length of the flexible member 53 in the left-right direction is longer than that of the pedal 23. The left and right end portions of the flexible member 53 are in sliding contact with the fixed plate portion 47 when the pedal 23 is rotated. On the lower surface of the front end of the flexible member 53, a clamping plate 55 is provided. The clamping plate 55 has the same length as the pedal 23 and the flexible member 53 in the left-right direction and extends in a band shape. That is, at a position slightly forward of the portion corresponding to the base end of the convex portion 23a of the pedal 23, the pedal 23, the flexible member 53, and the clamping plate 55 are sequentially stacked from top to bottom and extend in parallel, and the three are in the left-right direction. The width on the top is the same. The pedal 23, the flexible member 53, and the clamping plate 55 are fastened by fastening members 57 such as nuts and bolts. That is, the front end of the flexible member 53 is fixed by the fastening member 57.

At the front end of the pedal 23, a cylindrical portion 23b extending over the entire length in the left-right direction is formed. The pivot 21 is a round rod-shaped member, and its left and right end portions are respectively inserted and penetrated through the upper part of the left and right fixed plate portion 47. The pivot 21 is inserted into and penetrates the cylindrical portion 23b. That is, the front end of the pedal 23 is pivotally supported by the pivot shaft 21 so that the pedal 23 is free to rotate. On the outer peripheral surface of the cylindrical portion 23b, a restricting portion 23c protruding radially outward is formed.

Coil springs 27 as urging members are provided at both ends of the pivot shaft 21. The coil spring 27 urges the pedal 23 upward. The restricting portion 23c formed on the cylindrical portion 23b abuts against the flange portion 13b on the upper side of the second frame member 13 adjacent to the front, thereby maintaining the pedal 23 in the substantially horizontal initial posture. Since the pedal 23 is substantially horizontal in the initial posture, when an object other than the vehicle passes the pedal 23, the object can be prevented from being caught on the pedal 23.

To each top plate portion 45, a spray pipe portion 29 is fixed by welding, and the spray pipe portion 29 is used to spray the washing liquid in the working chamber 25 to the vehicle. The injection pipe portion 29 is a tubular member extending in the vertical direction. Its inlet end (upstream end) is located in the working chamber 25, and after extending upward from the inlet end, its outlet side (downstream side) end is on the top plate. The upper part of 45 is curved so as to be inclined upward as it approaches the inner side in the left-right direction. A plurality of (four in this embodiment) injection pipe portions 29 are arranged side by side on each top plate portion 45 in the front-rear direction. The end portions on the outlet side of the plurality of ejection tube portions 29 arranged on each top plate portion 45 face different angles, respectively. That is, the plurality of injection pipe portions 29 arranged on each top plate portion 45 have the first injection pipe portion 29 and the second injection pipe portion 29 whose inclination angles of the ends on the outlet side are different from each other. The end portion on the inlet side of each injection pipe portion 29 is formed in a tapered shape with a smaller diameter as it goes upward. That is, the cross-sectional area of the injection pipe portion 29 gradually decreases in the direction from the inlet side to the outlet side.

The check valve 31 constitutes the bottom of the working chamber 25. The check valve 31 is provided to block the introduction port 59 formed between the end of the extension 39 of the front wall 33 and the end of the rear wall 41, and the check valve 31 allows the cleaning fluid to flow from the cleaning tank 2 into the work Chamber 25, and prevent the washing liquid from flowing from the working chamber 25 to the washing tank 2. The check valve 31 has a shaft portion 31a and a plate-shaped valve body 31b extending from the shaft portion 31a. The shaft portion 31a is provided on the lower surface of the extension portion 39, and the valve body 31b is freely rotated by the shaft portion 31a. When the tire T of the vehicle passes the pedal 23 and the pedal 23 rotates downward from the initial posture to become the pressurized posture, the valve body 31b rotates downward (refer to the two-dot chain line in FIG. 5), and the top end of the valve body 31b and The rear wall 41 abuts, thereby closing the introduction port 59. In this way, the working chamber 25 is compressed and contracted. On the other hand, when the tire T passes the pedal 23 and the pedal 23 is rotated upward from the pressurized posture by the force of the coil spring 27 to return to the initial posture, the valve body 31b rotates upward (refer to the solid line in FIG. 5), and the valve The abutment between the top end of the body 31b and the rear wall 41 is released, thereby opening the introduction port 59. In this way, the cleaning liquid in the cleaning tank 2 is introduced into the working chamber 25. A hole 31c extending in the left-right direction is intermittently formed at the tip of the valve body 31b.

-Washing work- With respect to the tire cleaning device 1, when a vehicle passes through the cleaning tank 2, the lower end of the tire T of the vehicle is immersed in the cleaning liquid filled in the cleaning tank 2. The pumping device 17 is pressurized by the weight of the vehicle, and sprays the washing liquid in the working chamber 25 to the tire T. In this way, sludge and the like attached to the surface of the tire T are cleaned.

Specifically, the tires T of the vehicle sequentially pass on the pedal 23 of the pumping device 17. At this time, as shown in FIG. 6, the tire T is not pressed to the rear end of the pedal 23 but to the protrusion 49 provided at the front of the pedal 23. When the tire T climbs onto the protrusion 49, the weight of the vehicle resists the force applied by the coil spring 27, the pedal 23 rotates downward from the initial posture to change to the pressurized posture, and the working chamber 25 is pressurized. Then, the cleaning liquid in the working chamber 25 is sprayed out from the spray hole 13 d of the second frame member 13 and the spray pipe part 29. In this way, the tire T is cleaned by spraying the cleaning liquid on the circumferential surface and the side surface of the tire T.

The cleaning fluid in the working chamber 25 is sprayed forward from the hole 31c of the valve body 31b into the cleaning tank 2. Using its hydraulic pressure, the mud and sand accumulated in the lower part of the cleaning tank 2 are collected in the front part of the cleaning tank 2. Mud discharge part 4 (refer to Figure 2).

On the other hand, when the tire T passes the pedal 23, the pedal 23 is rotated upward from the pressurized posture by the force applied by the coil spring 27 to return to the initial posture. At this time, the inside of the working chamber 25 becomes negative pressure, and the cleaning liquid in the cleaning tank 2 is sucked into the working chamber 25 from the spray hole 13d. The valve body 31 b of the check valve 31 rotates upward, and the cleaning liquid in the lower part of the cleaning tank 2 is sucked into the working chamber 25 from the inlet 59.

As described above, whenever the tire T of the vehicle climbs onto the protrusion 49 of the pedal 23 of the pumping device 17, the cleaning fluid is sprayed from the injection hole 13d and the injection pipe portion 29 to the tire T to wash the tire T, and , The sludge in the washing tank 2 is collected from the hole 31c of the valve body 31b to the sludge discharge part 4.

-Effects of the embodiment- Therefore, according to the present embodiment, since the end of the pedal 23 on the front side is pivotally supported to allow the pedal 23 to rotate freely, the pedal 23 rotates so as to approach the vehicle when the vehicle passes. Therefore, the rotation speed of the pedal 23 is high, and the hydraulic pressure of the washing liquid sprayed to the tire T can be made strong.

In addition, the flexible member 53 protrudes further to the rear side than the end portion on the rear side of the pedal 23. Therefore, when sand or the like moves from the upper surface of the tread 23 to the rear of the tread, the sand or the like will not be caught between the rear wall 41 of the working chamber 25 and the tread 23, but will be caught Between the rear wall 41 and the flexible member 53. In this way, gravel and the like are sandwiched between the pedal 23 which is a rigid member and the rear wall 41, and it is possible to prevent the rotation of the pedal 23 from being hindered.

Furthermore, the flexible member 53 is provided on the lower surface of the pedal 23. Therefore, when the pedal 23 rotates downward due to the weight of the vehicle, the flexible member 53 is supported by the pedal 23, and deformation is restricted. On the other hand, when the pedal 23 is rotated upward by the action of the coil spring 27, the flexible member 53 is deformed by the hydraulic pressure of the liquid in the working chamber 25, so the sand and gravel in the clamped state will not continue. While maintaining this state, it drops toward the bottom of the working room 25.

In addition, the vehicle passing above the pedal 23 presses the protrusion 49, which is formed on the front side, that is, near the portion where the pedal 23 is pivotally supported. Therefore, compared with the case where the vehicle is pressed to the rear end of the pedal 23, the rotation speed of the pedal 23 is faster.

In addition, the injection pipe portion 29 is provided on a top plate portion 45 independent of the pedal 23. Therefore, due to the rotation of the pedal 23, the outlet end of the injection pipe portion 29 will not be located below the liquid level in the working chamber 25. In this way, by using the liquid in the working chamber 25, it is possible to prevent the hydraulic pressure of the sprayed cleaning liquid from decreasing. Furthermore, since the cleaning liquid is ejected through the ejection pipe portion 29 extending up and down in the working chamber 25, the ejection direction of the cleaning liquid can be set in a desired direction.

In addition, the cross-sectional area of the inlet end of the injection pipe portion 29 is larger than the cross-sectional area of the outlet end. Therefore, the hydraulic pressure sprayed from the spray pipe portion 29 can be made stronger.

Furthermore, the end portions on the outlet side of the plurality of ejection tube portions 29 arranged side by side on each top plate portion 45 face different angles. Therefore, the liquid ejected from the ejection tube portion 29 is ejected in a plurality of directions. In this way, the range of vehicles that can be washed is larger.

In addition, the pumping device 17 and the body frame 15 are independent of each other. Therefore, for example, when the pump 17 device fails, the repair of the tire cleaning device 1 can be completed by only replacing the failed pump device 17.

In addition, the injection hole 13 d is provided in the flange portion 13 b on the upper side of the first frame member 11 independent of the pedal 23. Therefore, due to the rotation of the pedal 23, the injection hole 13d is not located on the lower side of the liquid surface in the working chamber 25. In this way, the liquid in the working chamber 25 can prevent the hydraulic pressure of the cleaning liquid sprayed from the spray hole 13d from falling.

In addition, the attached matter such as mud and sand removed from the tire T and the attached matter accumulated on the pedal 23 can be discharged through the discharge port 44. Therefore, it is possible to reduce the amount of deposits accumulated on the pedal 23 and the main body frame 15.

(Other embodiments) The above-mentioned embodiments may also adopt the following configurations.

In the above-mentioned embodiment, the deep-bottomed sludge discharging part 4 is provided in the left and right direction in the front part of the left and right washing tank 2 so as to extend to the side, so that the sludge in the washing tank 2 is concentrated to the sludge discharging part 4 . However, it is also possible to provide a conveyor belt for sludge discharge in the sludge discharge part 4 to automatically discharge the sludge collected in the sludge discharge part 4 out of the cleaning tank 2. 〔Industry availability〕

In summary, the present invention is useful for a vehicle attachment removal device for cleaning sludge attached to the tires of the vehicle and the lower part of the vehicle body.
