Description

[Detailed Description of the Invention] Gate-type car wash machines that cross over vehicles and wash them with brushes while running usually have a maximum height of 27n1 and a vehicle height of 2.0 cm.
It is designed to wash vehicles of 771 and below.

The reason for this is that the height of the loading platform of a normal truck used to transport a gate-type car wash is approximately 1.17 mm. ? Therefore, when transporting a car wash machine, the total height must be 3.3, which is the legal height limit.
This is to make it 77Z or less.

Therefore, vehicle height 2. Able to wash vehicles of Ottx and above.
In order to transport a large car wash machine with a height of 2.7771 cm or more, it is necessary to use a trailer or the like, which results in high transportation costs. For this reason, car wash machines were transported separately into upper and lower parts and assembled at the installation site.

However, since most of the installation sites were gas stations, welding was not possible and everything was assembled using bolts, which resulted in a complex structure and increased weight. The assembly cost was high because the work was carried out on a business trip.

In addition, the demand for large car wash machines is significantly lower than that of regular car wash machines, so the power consumed to operate the car wash machine is less expensive than normal cars, which are relatively expensive and need to be washed frequently. The cost was also relatively high.

Based on the above-mentioned circumstances, originally, vehicles with high vehicle height should be
Since manual car washing is difficult, car wash machines for such vehicles are not widespread despite the effectiveness of mechanical car washes.

In the present invention, the height and car washing mechanism of the car wash machine are the same as those of a normal car wash machine, and ordinary cars can be washed in the same way as before. This invention relates to an elevating type car wash machine that solves the above-mentioned problems by raising the car to wash the car.

Hereinafter, a detailed description will be given based on embodiments shown in the accompanying drawings.

Figures 1 and 2 schematically illustrate the car wash machine of the present invention.
1) is the main body of the car wash machine, (2), (3), and (4) are the top brush, side brush, and rocker brush installed on the main body (+1), and (5) is a known method using ultrasonic waves or infrared rays. The vehicle height detector (6) is a running rail, and the mechanism for washing the vehicle using brushes (2) (3) (41) is the same as that of a conventional car wash machine, and illustrations and explanations thereof will be omitted.

As shown in Fig. 3, both legs (1a) (+
a) At the front lower end of each frame (7) at the lower end (lower right end in Figure 3), there is a frame that faces rearward and slopes slightly downward.
A pair of left and right outer lift arms (8) parallel to each other (
8) is pivotally installed with a support shaft (9), and at its rear end,
A traveling drive wheel (II+) is pivotally supported by a drive axle 00), and both outer lift arms (8) (81) are connected to each other by a connection plate (In2).

At the rear lower end of the frame, there are a pair of left and right inner lift arms (8) that face forward, slope slightly downward, are parallel to each other, and intersect in an X-shape with both outer lift arms (8) (8). A lift arm (13) 031 is pivotally installed with a support shaft (+4+), and at its front end, a driven wheel 06 for traveling with a driven axle 0■ is pivotally supported, and both inner foot arms 0
3) α3) are connected to each other by a connecting plate 07).

As will be described later, αQ is a stopper that is fixed to the connecting plate a02 so as to come into contact with each inner lift arm 03) when the car wash machine main body (1) descends to the lower limit. .

A support (20) facing upward is erected on the mounting plate installed between the rear ends of the upper surfaces of both outer lift arms (8) (81), and a mounting bracket (21) is installed on the upper front end of the support Through the reducer (2) and synchronous motor (23) as shown
is permanently installed.

As shown in Fig. 4, an endless chain (26) is connected to the reducer (sprocket H attached to the output shaft of 22+) and the sprocket (25) fitted to the drive axle α0). -It is.

Therefore, as will be described later, the car wash machine body +1+ moves up and down,
Even if the support column (20) swings relative to the drive axle (10), the car wash machine can be driven by the motor (23) without any problem.

At the center of the upper surface of both outer lift arms (81 (8) and both inner lift arms (+3) (13),
The protrusions (2η(27+ and (28) Axis C
1) and 00) are connected.

A jack stand (3I) is fixed to the center of the upper surface of the frame, and is shaped like a front downward U cage, and its opposing left and right inner surfaces face vertically and parallel to each other. The eggplant guide rod (32) Cl2) is fixed.

The horizontal central piece of the jack stand 01) has a sixth
As shown in the figure, there is a box C33), a worm C35) which faces the front-rear direction and is rotated by a synchronous motor C14+ fixed to the rear surface of the box 03), and a worm C35) whose teeth are cut into the outer peripheral surface. It is equipped with a vertical screw hole (36a) in the center, and is rotatable in the box c33).
And a worm wheel (3G) that is installed so that it cannot move up and down.
and the worm wheel (screwed pestle 07), which is screwed into the screw hole 30 (+6a) and passes through the box body 03) and moves up and down by the rotation of the motor (34), facing the 10F direction. The screw jack □□□ is fixed.

A second screw hole inserted through the lower end of the screw punch t37) in the left and right direction.
The pivot (39) is connected to the first pivot (21m) by a push rod (4H11), and each roller (42) is pivoted at both ends of the second pivot (09) to guide the jack stand (1). The rod (32 (3a) is engaged with the rod so that it can be raised and lowered.

The above-mentioned lifting device is also provided on the opposite leg of the main body ( ).

When washing a car, this car wash machine first measures the height of the vehicle using a vehicle height detector (5), and if the car height is 2 m or less, for example, the car is washed in the same way as a conventional car wash machine.

If the vehicle height is 2 m or more, start the motor 04) and push down the screw jack 0η of 1381.

Then, both outer lift arms (8) (8) and both inner lift arms (+3+ (+31 are the push rods (40
) (Spindle (9) pushed down by 411 (1
4) Swinging downward, the drive axle 01) and the driven wheel (16) roll toward each other on the rail CG+, and at this time both lift arms (8) (810■(1
Due to the reaction of step 3), the frame (7) is pushed up.

When the frame (force) and the car wash machine body (1) rise to a predetermined height, the motor C34+ stops and
The motor (231) starts and the car wash machine moves forward to wash the car.

As mentioned above, the car wash machine of the present invention can transport the lower finished product of the main body (1) in a normal truck, does not require assembly work at the installation site, and is convenient and inexpensive to transport. .

In addition, since the structure of the main body (1) is the same as that of conventional products manufactured in large quantities, even if the elevating device of the above-mentioned main body (1) is added, it will be cheaper than a special large-sized one that is in low demand. In addition, the operating power cost is the same as that of conventional vehicles in the case of ordinary vehicles that are washed most frequently, and even in the case of special vehicles with a high vehicle height, only the lifting power of the main body (1) is required. is added, and the amount is small.

Note that when the main body (1) is raised, the lower ends of the roaring side brush (3) and rocker brush (4) are also raised, but since the floor surface of a high vehicle is also high, there is virtually nothing left to wash. will not occur.

In addition, in the above-mentioned embodiment, the push rod f41j (11+
Although a screw jack was used to push down, a hydraulic cylinder or pneumatic cylinder combined with a synchronization mechanism may be used instead.
