Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an automatic car washing device for special vehicles such as vacuum vehicles.

[Conventional technology and its problems]

Conventionally, as a car wash device for special cars such as vacuum cars, a car wash spray is installed on the inside of a washing frame that surrounds both sides and the ceiling of the special car, and water is sprayed from this car wash spray to wash the special car. There is something I did.

However, there are small and large types of special vehicles such as vacuum vehicles, and the width of small and large vehicles differs greatly, so conventionally, the cleaning equipment was also
Two types were needed: one for large cars with a wide cleaning frame and one for small cars with a narrow cleaning frame.

In addition, when washing a small car with a washing device designed for large cars, the distance from the side of the washing frame to the side of the small car is long, so the washing water from the washing spray does not hit the small car with force, resulting in poor cleaning performance. There was a problem.

Therefore, this invention aims to provide an automatic car washing device for special vehicles that can wash both small and large cars in the same way.

[Means for solving problems]

The automatic car wash device of this invention consists of a washing frame that surrounds both sides and the ceiling of a special vehicle, consisting of a fixed frame and a movable frame that is movable in the width direction, and a car washing spray is provided on the inner surface of the washing frame. , a driving means for moving the movable frame in the width direction is provided, a vehicle type detecting means for detecting whether the special vehicle is a small car or a large vehicle is provided on the front side of the washing frame, and a vehicle type detecting means is provided between the vehicle type detecting means and the washing frame. A position detection means for detecting passage of a special vehicle is provided, and a drive signal is output to the drive means of the movable frame based on the vehicle type detection signal of the vehicle type detection means, and a drive signal is output to the drive means of the movable frame based on the position detection signal of the position detection means. The present invention is characterized in that the car wash spray is provided with a control section that outputs a car wash start signal.

[Effect]

In the automatic car wash device having the above structure, first, on the front side of the washing frame, whether the car is a small car or a large car is detected by the car type detection means. For example, if this vehicle type detection means detects that a special vehicle is a large vehicle,
This detection signal is sent to the control unit, and the control unit outputs a drive signal to the drive means of the movable frame to move the movable frame outward. Spread to fit width. Next, when the special vehicle comes closer to the front side of the washing frame, the passing of the special vehicle is detected by the position detection means, this position detection signal is sent to the control unit, and the control unit uses car wash spray to start washing the car. A signal is output, and the car wash spray sprays washing water.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The cleaning frame 1 is constructed by a fixed frame 2 and a movable frame 3 that is movable in the width direction.
installed so as to surround both sides and ceiling of the In the embodiment shown in FIGS. 1 and 2, one side surface is constituted by a movable frame 3, and the other side surface and the ceiling surface are constituted by a fixed frame 2. Furthermore, in the case of the embodiment shown in FIGS. 3 and 4, one side surface and half of the ceiling surface are formed by the movable frame 3, and the other half of the other side surface is formed by the fixed frame 2. The ceiling surfaces of the movable frame 3 and the fixed frame 2 are made to overlap each other within the movement range of the movable frame 3.

The width of the cleaning frame 1 is set such that a small car can pass through when the movable frame 3 is moved inward, and a large car can pass when the movable frame 3 is moved outward.

The movable frame 3 is provided with a driving means 4 for moving the movable frame 3 in the width direction.
This driving means 4 includes a motor, a piston, and the like.

A car washing spray for spraying washing water is installed on the inner surface of the washing frame 1.

A vehicle type detection means 6 for detecting whether the special vehicle A is a small vehicle or a large vehicle is provided on the path for special vehicles in front of the cleaning frame 1. The vehicle type detection means 6 includes means for determining whether a special vehicle is a small vehicle or a large vehicle by detecting the width of the special vehicle using a phototube or by detecting the weight of the special vehicle using a load cell.

When the vehicle type detection means 6 detects whether the special vehicle A is a small vehicle or a large vehicle, this detection signal is sent to the control section 7, and from the control section 7 to the drive means 4 of the movable frame 3. In the case of a small car, a drive signal is output to move the movable frame 3 inward, and in the case of a large car, a drive signal is output to move the movable frame 3 outward; Therefore, the movable frame 3 moves to a position that matches the width of the small car or large car.

Next, just in front of the cleaning frame 1, a position detection means 8 is installed to detect when the special vehicle A has arrived just in front of the cleaning frame 1. This position detection means 8 may be a phototube or a load cell.

When the position detecting means 8 detects that the special vehicle A is in front of the washing frame 1, this detection signal is sent to the control section 7, and the control section 7 outputs a car wash start signal to the car wash spray. Washing water is sprayed from the car washing spray, and the special car A passing through the washing frame 1 is washed.

Thereafter, a stop signal for the car wash spray is output after a certain period of time has elapsed by a timer, or based on a detection signal from a phototube or the like that detects the passage of the special vehicle A behind the washing frame 1. Then, the car wash spray will stop spraying washing water.

[Effect of idea]

According to this invention, as described above, the width of the cleaning frame automatically changes depending on whether it is a small car or a large car, so it is possible to effectively wash special cars of different types with one car wash device. There is an effect that it can be done.

Furthermore, since the washing water is sprayed from the car washing spray just before the special vehicle reaches the washing frame, there is also the effect of preventing wastage of washing water.
