Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a floor cleaning machine (scrubber) for cleaning a floor by rotating a cleaning brush while supplying cleaning water. The present invention relates to a boarding type floor washer that operates a floor washer while sitting on a cab provided on a vehicle body.

[0002]

2. Description of the Related Art A floor cleaning machine for cleaning a floor surface with a cleaning brush includes a self-propelled walking type in which an operator walks while walking, for example, as disclosed in Japanese Utility Model Publication No. 2-1729929. There is a boarding type in which an operator sits on a driver's cab as seen in Japanese Utility Model Laid-Open No. 2-59757, and a self-propelled walking type floor cleaning machine is used for cleaning a general floor surface.
The boarding type floor cleaning machine is used for cleaning a large floor surface such as a gymnasium or a factory.

In addition, most of the above floor cleaning machines use a battery as a drive source of a motor mainly from the point of use indoors, and the battery and a tank for storing cleaning water and dirty water are used together. Since it has to be mounted on the vehicle body, there is a problem that the entire vehicle body becomes large and heavy. Especially, in the case of the boarding type, the vehicle body itself is large in addition to one cleaning time. However, it is necessary to mount a large number of large batteries, and as a result, the vehicle body becomes larger.

Therefore, it has been considered to reduce the size of the entire vehicle body by accommodating the above battery in the lower part of the driver's cab or tank.

[0005]

However, when the battery is used as a power source, it is necessary to relatively frequently perform various maintenance such as inspection of the battery, replacement of the battery fluid, or replacement of the battery itself. Therefore, if the battery is housed inside the inner surface of which the upper surface is covered with a driver's cab or a tank, the above maintenance becomes very difficult to perform, which causes a problem in the work.

Therefore, a technical object of the present invention is to prevent the vehicle body of the boarding type floor washer from being unnecessarily enlarged, and
It is to facilitate various maintenance for the installed battery by opening its upper surface.

[0007]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows.

[0008] In a boarding type floor washer for operating a floor washer while sitting on a cab provided on a vehicle body,

(1) The driver's cab is provided on the front upper surface of the vehicle body so that the operator's cab can be laid sideways or forward to the vehicle body, and a driving battery is mounted on the rear upper surface of the vehicle body. Similarly, on the upper surface of the rear part of the vehicle body, the inside of the lower side is used as a storage chamber for the battery, and the upper side is provided with a mounting base on which a storage tank for cleaning water and dirty water is mounted. The mounting table is configured to be slidable toward the front upper surface of the vehicle body on which the driver's cab is laid down so that the battery can be exposed.

(2) Wheels for movement are attached to the left and right sides of the mounting table, and guide rails for guiding the movement of the wheels are provided on the upper surface of the vehicle body.

(3) A foldable stand is provided on the side surface of the driver's cab to support the operator's cab which has been laid sideways in a substantially horizontal state.

(4) Various electric components such as a suction blower that exerts a suction action on the squeegee are provided on the vehicle body inside the lower side of the cab.

According to the above-mentioned means (1), since the battery is housed in the lower part of the tank containing the wash water and the dirty water, it is not necessary to make the vehicle body larger than necessary for the battery, and the boarding is not necessary. While allowing downsizing of the floor cleaning system, the various maintenance work for the battery can be done by first tilting the driver's sideways and then sliding the mounting table equipped with the storage tank to the front upper surface position of the vehicle body. ,
Since the battery is exposed and the upper surface of the battery is opened, the above various maintenances can be easily performed.

According to the means described in (2) above, since the mounting table on which the storage tank is mounted can be moved extremely smoothly by the wheels and the guide rails, the mounting table for opening the upper surface of the battery is moved. It is possible to complete the movement and the return movement of the mounting table that closes the upper surface of the battery and returns it to the operating state within a short time with a small force.

According to the means described in the above (3), if the folding stand is rotated and set when the driver's cab is laid down sideways, the driver's cab can be supported in a substantially horizontal state. The driver's cab will not be damaged by hitting it on the floor, and when returning it to the original state, it will be possible to easily set it back by rotating it with relatively little force. .

According to the means described in (4) above, when the driver's cab is laid down on its side, various electric components such as a suction blower and a water supply pump provided inside the driver's cab are provided on the vehicle body. Since it is installed on the upper surface side and does not rotate together with the cab, the cab can be easily laid down and restored and rotated with a small amount of force, and the electrical components of various electrical components due to vibrations or shocks can be electrically operated. It also makes it possible to reduce the number of malfunctions.

As described above, the above (1) to (1)
The technical problems described above can be solved by the means described in (4), and the problems of the above-mentioned conventional technology can be solved.
