Description

[Detailed Description of the Invention] This invention provides a vehicle with wheels attached to the vehicle.
This invention relates to a wheel cleaning device that can clean wheels.

Conventionally, this type of wheel cleaning device has two or four rotating rollers arranged at intervals corresponding to the axle spacing of the vehicle and the wheel spacing.・The rear wheels are placed on each side, and the drive wheels of the vehicle are driven and rotated to clean the wheels.

However, in such a device, since the axle spacing and wheel spacing of the vehicle differ depending on the manufacturer and vehicle model, the spacing between the rotating rollers should be adjusted in accordance with the axle spacing and wheel spacing of the vehicle to be cleaned each time. In addition to the inconvenience of having to adjust each interval,
Those in which such adjustment is not possible have the disadvantage that the number of vehicles to be cleaned must be restricted, and the driven wheels of the vehicle cannot usually be cleaned.

This invention eliminates the drawbacks of the conventional ones as mentioned above,
It is an object of the present invention to provide a wheel cleaning device that can clean wheels regardless of the axle spacing and wheel spacing of a vehicle, and can clean driving wheels and driven wheels simultaneously.

The present invention will be described with reference to embodiments shown in the drawings.

1 in FIG. 1 shows a wheel cleaning device, and this cleaning device 1 consists of a machine base 2, a belt pulley 3 supported on the front end of the machine base 2, and a take-up 4 supported on the rear end of the machine base 2. The belt pulley 5 includes a belt pulley 5, and two rubber belts 6 wound between the belt pulleys 3 and 5 so as to be able to run laterally.

A plurality of carrier rollers 7 supporting both belts 6 from below are supported on the machine base 2 at predetermined intervals.

An annular groove 8 is recessed around the outer periphery of these carrier rollers 7 and belt pulleys 3 and 5, and a protrusion 9 protruding from the back surface of the belt 6 engages in this groove 8, so that the belt 6 is It is designed not to separate from the cars 3, 5 and the carrier roller 7.

A vehicle 10 enters and is placed on the belt 6 while being supported by the carrier roller 7.

A maintenance device 11 for maintaining the vehicle 10 in a predetermined position is attached to the front end of the machine platform 2.

This maintenance device 11 includes a rotating shaft 13 supported on the machine base 2 in parallel with the belt pulleys 3 and 5.

The base end of a swing cam 14 is fixed to one end of this shaft 13, and the base end of a link 15 is fixed to the other end.

An elongated hole 16 is bored in the tip of the link 15, and a pin 18 protruding from the tip of the link 17 is inserted into the elongated hole 16. It is pivotally supported on machine base 2.

A long hole 19 is provided in the center of this link 17 as shown in FIG.
A pin 20 is inserted into the elongated hole 19. One end of each wire rope 21, 22 is fixed to the pin 20, and a handle 25 is attached to the other end of the rope 21. A handle 26 is fixed to the other end of 22, respectively.

These handles 25 and 26 are both connected to the vehicle 1 via pulleys.
They are each suspended to the side of the 0 driver's cab.

An elevating platform 28, which is located above the swing cam 14 and is formed by connecting two shafts to the machine base 2, is attached via a guide 23 so as to be movable up and down.

As shown in FIG. 1, a stopper 29 having a recess 24 is fixed to the upper end of the lifting platform 28, and a cam flower 30 is attached to the lower end of the platform 28. It engages surface 31.

This platform 28 is raised to its upper limit position, and the recess 24 of the stopper 29 holds the front wheel axle 32 to which the driven front wheel 33 of the vehicle 10 is attached, thereby maintaining the vehicle 10 in the stopped position. It has become.

A base end of a swing pawl 35 is pivotally supported at the front end of one side of the machine base 2, and the tip of the pawl 35 is removably engaged with a ratchet wheel 38 which is coaxially fixed to the belt pulley 3. It is designed to match.

Furthermore, one end of a wire 36 is fixed to the tip of this claw 35, and the other end of this wire 36 is fixed to the wire rope 21 via a connector.

When the pawl 35 and the ratchet wheel 38 engage, the belt pulley 3
is biased so that it does not rotate, and the belt 6 is prevented from running.

Reference numeral 27 is a recess provided at the tip of the cam surface of the cam 14.

Further, 12 is an inclined crown for preventing meandering of the front wheel 33 and the driving rear wheel 34, 37 is a return roller, and 39 is a coupling.

Next, the use of the above will be explained.

In the normal state, the handle 26 is pulled downward, so that the pawl 35 engages the ratchet wheel 38, and the belt pulley 3 is urged not to rotate clockwise in FIG. The belt 6 cannot run.

At the same time, the table 28 is lowered to the lower limit position.

In such a state, the vehicle 10 is advanced onto the belt 6 from the rear end of the machine platform 2, and the vehicle 10 is guided by a mark (not shown), that is, with the front wheel axle 32 of the vehicle 10 as a guide. It is positioned above the recess 24 of the stand 28 and stopped.

When the handle 25 is then pulled downward from the cab of the vehicle 10, the link 17 swings clockwise in FIG. 1, and the link 15, and therefore the cam 14, swings counterclockwise.

This rocking of the cam 14 is caused by the fact that the recess 27 is connected to the shaft 13 and the base 27.
It stops when it crosses the center line connecting it to the recess 24, and this stopped state is maintained by both links 15 and 17.

As a result, the platform 28 is maintained raised to the upper limit position, and the stopper 29 holds the front wheel axle 32 of the vehicle 10.

At the same time, the pawl 35 swings clockwise about its support shaft, and the engagement between the pawl 35 and the ratchet wheel 38 is released (FIG. 1).

When this happens, operate the traveling device of the vehicle 10 to change the traveling speed of the vehicle 10 from 60 km/h to 80 km/h.
When the rear wheels 34 are driven to rotate at a rotation speed of km/H, the rear wheels 34 are rotated while the vehicle 10 is maintained at a predetermined position on the machine base 2.
rotates while running the belt 6.

As the belt 6 runs, the front wheels 33 in contact with it rotate, and the sludge adhering to the front wheels 33 and rear wheels 34 is blown away by centrifugal force or removed by friction with the belt 6. , all wheels are cleaned.

After the wheels 33 and 34 have been cleaned in this way, operate the traveling device of the vehicle 10 in the opposite manner to the above to clean the rear wheels 33 and 34.
4 is stopped, and then the handle 26 is pulled downward, the link 17 swings counterclockwise in FIG. The table 28 that was being held is lowered.

This causes the stopper 29 to descend, and at the same time the claw 3
5 engages with the ratchet wheel 38 again, and the belt 6 is no longer able to travel.

5 to 7, in which the vehicle 10 is moved forward and separated from the cleaning device 1, show another embodiment of the present invention, and in this embodiment, a considerable portion is shown in FIGS. 1 to 4. Since the configuration is almost the same as that of the embodiment, the same reference numerals will be given to those parts and the explanation will be omitted, and the different configuration will be mainly explained.

4 which are located on both sides of both rubber belts 6 and branched from the water conduit 40 from the front end to the center of the machine base 2.
A main branch pipe 41 is provided.

A riser pipe 42 is connected to each branch pipe 41 at a position where the front wheels 33 and rear wheels 34 of the vehicle 10 are stopped, which are the mounting positions of the base 28, respectively. A plurality of injection nozzles 43 are attached to the front and rear wheels 33, 34 to inject water.

44 is a stop valve.

In the embodiments shown in FIGS. 8 to 10, one wide rubber belt 56 is used instead of the two rubber belts 6, and a maintenance device 58 is used instead of the maintenance device 11.

In accordance with the adoption of the rubber belt 56, a machine base 52, belt pulleys 53 and 55, and a carrier roller 57 are adopted.

The maintenance device 58 includes a rotation shaft 46 supported on the front end of the machine base 52 in parallel with the belt pulley 53, and a swing frame 47 whose base end is fixed to the shaft 46.

Further, the base end of a link 48 is fixed to the outer end of this shaft 46, and the front end of a cam 49 engages with the front end of this link 48, and the base end of this cam 49 is supported by a machine base 52. The rotary shaft 50 is fixed to the rotary shaft 50.

The other end of a wire 51, one end of which is fixed to the rope 21, is wound around the drum fixed to this shaft 50, and when the handle 25 is pulled downward, the swing frame 47 moves to the eighth
It is swung counterclockwise in the figure to ensure that the recess 59 formed at the tip of the oscillating frame 7 is engaged with the front wheel axle 32 of the vehicle 10, and the handle 26 is pulled downward. Then, the swing frame 47 swings in the opposite manner to the above.

In each of the embodiments shown in Figures 5 to 10, the wheels 33 and 34 are cleaned in substantially the same manner as in the embodiments shown in Figures 1 to 4.

This invention is as described above, in which a pair of belt wheels and a number of carrier rollers are horizontally supported on a machine frame, and the belts are wound around these belt wheels and the carrier rollers. The machine frame is further provided with a travel stop member that temporarily enables the belt to travel, and a maintenance member that temporarily maintains a vehicle that has entered the top surface of the belt in a predetermined position, and the travel stop member and a maintenance member actuated by an actuating member provided in the middle of the cable whose ends are located in the driver's cab of the approaching vehicle, and when one end of the cable is pulled during wheel cleaning; The traveling stop member allows the belt to run, and the retaining member maintains the vehicle in a predetermined position, so that a vehicle can be placed on the belt regardless of the axle spacing and wheel spacing. In addition to being able to clean the wheels of vehicles of all makes and models, the belt runs in contact with the driving wheels of the vehicle, and as the belt runs, the driven wheels rotate, cleaning all the wheels of the vehicle at the same time. In addition, the vehicle is maintained in a predetermined position by the maintenance member, and the wheel cleaning operation can be performed extremely safely.
The vehicle can easily enter and exit the belt by the vehicle itself, and the cleaning device itself does not require any power, and is therefore extremely simple in construction and easy to handle. It is effective in that it can be provided economically.

In addition, since the rotation of a pair of belt pulleys and a large number of carrier rollers is mutually transmitted by the belt, the rotational speed of the front and rear wheels of a vehicle that has entered the belt can be adjusted to the rotational speed necessary to quickly clean the vehicle with small power. Furthermore, the sludge that falls from the wheels during wheel cleaning is conveyed to one place by this belt at the same time as cleaning, eliminating the need to install a separate belt conveyor for sludge conveyance. Furthermore, since both ends of the traveling stop member and the maintenance member are operated by cables located near the driver's cab of the entering vehicle, when cleaning the wheels, the driver remains in the vehicle and the cables are removed. The belt can be moved by simply pulling one end of the belt, and
This has the advantage that the vehicle is maintained in a predetermined position and therefore not only can preparations for such wheel cleaning be carried out quickly, but also that no other auxiliary personnel are required.
