Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a brushing and cleaning device. More particularly, it relates to apparatus for cleaning vertical surfaces such as shipping containers, transportation vehicles, and buildings.

(Conventional technology) Vertical surfaces such as shipping containers, transport vehicles such as moving furniture trucks, side walls of refrigerator trucks, and walls of buildings have traditionally been cleaned by hand using high-pressure water jets, paddles, etc. was doing.

High-pressure water jets are suitable for removing light dust build-up on vehicles, containers, and buildings, as mentioned above, but removing a film of dirt from surfaces requires a blower or some other method of scrubbing. do.

U.S. Pat. No. 2,838,198 discloses a portable brushing device for cleaning vehicles of the type that are transported from place to place. This brushing device is attached to the fork of a forklift truck. This brushing device consists of a water storage tank, a pump and a valve that provide a water spraying function to a brush that rotates around a vertical axis, and the brush is attached to a vertically reciprocating bar. There is. A power unit is installed on the tank and drives a hydraulic pump to rotate the brush and reciprocate the bar in the vertical direction.

Further, the lever control means is driven by the power section to automatically control the operation.

U.S. Pat. No. 2,950,492 discloses a portable vehicle cleaning device mounted on a road transport vehicle. This cleaning device has a cylindrical brush that rotates about a vertical axis. This brush can be moved laterally and longitudinally of the vehicle.

This brush is mounted on a carriage so that the brush can be moved from one working position to another to provide a constant pressure on the surface to be cleaned.

U.S. Pat. No. 2,854,1380 discloses a vehicle cleaning device in which brushes are suspended from an elevated rail. This cleaning device is immovable and cannot be transported to the cleaning area.

(Problems to be Solved by the Invention) An object of the present invention is to provide a portable brush cleaning device that is suitable for cleaning vertical surfaces.

(Means for solving the problem) In order to achieve the above object, a brushing and cleaning device installed on a moving vehicle such as a forklift truck, comprising a rotating brush, a series of sprays, etc. - has a nozzle, a tank for supplying water and cleaning agent, a pump for supplying water from this tank to the spray nozzle, a hydraulic motor driving a brush at one end,
The brush at the other end is designed to drive a pump.

Embodiment In one embodiment of the invention, the device is attached to a frame assembly l. This frame assembly has a structure in which the fork of a forklift O-truck can be placed in channel 2 and lifted to be transported. The frame assembly 1 is composed of a lower horizontal member 3, an upright portion 4, an upper member 5, and a bracing member 6.

Attach tank 7 and brush 8 to frame assembly 1. tank 7
contains water, if necessary with cleaning agent, and the brush 8 is constructed to rotate around a vertical axis. This brush 8 has a shape conventionally used in cleaning devices for motor vehicles and is shown in broken lines and only in part to avoid complication.

Preferably, the brushes are mounted on one side of a frame assembly l with a vertical member 9, which includes an extension arm 10 with bearings extending laterally of the member, and a brush shaft 11.
is provided.

In addition, there are spray nozzles 19 arranged vertically in group I.
is installed. The spray nozzle sprays water and cleaning agent onto the surface to be cleaned.

It is desirable to drive the brush 8 with hydraulic drive #J13.
This hydraulic motor can be fixed to the shaft center 11 of the brush at the upper end of the brush. The lower end of the brush axis 11 is attached to a bearing 14, which drives a pump 15, preferably via a step-up gear 16, from the tank 7 to the bottom of the spray tube 12 via a line 17.18. Send water. Blow tube 1
2 is equipped with a spray nozzle 18 and line 17 is equipped with a control/stop valve 24.

When the top end of the spray tube 12 is connected to the bottom, preferably with a venturi, the fitting at the bottom of the tank is connected to part 20, so that the water in the tank is thoroughly mixed with the cleaning agent.

The top spray tube, i.e. the spray tube at the opposite end of the spray tube from the inlet, has a regulating valve 23 so that the pressure in the spray tube and the spray nozzle is
It can be easily adjusted to obtain the desired spray pattern. Excess liquid is returned to the tank via a venturi fitting at the bottom of the tank.

Since the hydraulic prime mover 13 can be supplied with pressurized hydraulic fluid from the hydraulic system of the forklift truck, this can be done by disconnecting one of the hydraulic controllers from the hydraulic control valve and connecting the hydraulic pipe from the hydraulic system ih#JI. It is best to connect it to a water pressure control valve.

The forklift truck hydraulic controller has types of side-shifting movement, tilting movement or rotary movement, one of which can be separated and a hydraulic motor connected to it, and still raise and lower the forklift mechanism. .

Furthermore, a control valve is added to control the hydraulic motor, and
It is desirable to control the position of the brush using a side-shifting motion and a tilting or rotating motion.

A spray deflection guard can be attached to the frame near the brush to prevent spray from being directed toward forklift trucks or workers. The deflector extends from the spray tube around the brush.

The operation of this device will be explained below.

The brush can be rotated in either direction depending on which direction is selected by the control valve.

A spring-loaded reel 21 is provided on the frame set, and the penstock 22 can be wound around the reel 21 and unwound. You can raise and lower the forklift as desired. The spring-loaded reel 21 winds up the slack portion of the penstock in a low position and unwinds the penstock on the reel during the upward movement of the forklift.

Thus, a versatile mobile device for cleaning vertical surfaces is provided. If the vertical surface is uneven, the forklift can be tilted slightly to make it easier for the brush to fit into the depression. Irregular surfaces can be cleaned by rotating the brush in the opposite direction.

Therefore, when the device of the present invention is brought to the vertical surface to be cleaned, and in the case of a vertical surface such as a container or moving furniture vehicle, the device of the present invention is brought into the container or the vehicle to easily clean the vertical surface. can. There is no need to remove the container from the car, as the container itself can also be cleaned on the car.

In other embodiments, the driving force can be derived from other means. If desired, a small internal combustion engine, hydraulic pump, and hydraulic system can be mounted on the frame itself to create a system that can operate without the need for a hydraulic connection to the forklift truck's hydraulic system.

Also in this respect, the drive motor can be made into a small electric motor. Of course, this electric motor must be adequately protected from wash water.

(Effects of the Invention) Since the brush cleaning device configured as described above has a portable structure, it can be carried to shipping containers, transportation vehicles, and buildings to clean dirt on the vertical surfaces thereof.
