Description

[Detailed description of the invention] This invention relates to a cleaning machine that can clean the entire surface of a vehicle body such as a train using a rotating brush.
This invention mainly relates to washing machines used in car washes.

Currently, there are two types of cleaning devices used for external cleaning of rail vehicle bodies: fixed cleaning devices and self-propelled cleaning devices. In this method, the vehicle passes between the groups of cleaning brushes installed to clean the sides of the vehicle body. This system is capable of cleaning the sides of the car body by rotating and moving on its own, and even though it is a method of falling over, it has been effectively put into practical use in the past.

On the other hand, as for the means for cleaning the front and rear buttons and connecting parts of the car body, there are currently no suitable devices or equipment available. It is done by work.

However, carrying out cleaning work by hand not only requires a great deal of labor, but also poses many dangers such as falling of personnel. However, two major problems remain: labor saving and safety.

The present invention has been developed to solve the above problems, and the purpose of the present invention is to provide a self-propelled washing machine with the ability to clean the front and rear buttons and connecting parts. Therefore, it is an object of the present invention to provide a washing machine that can reliably and effectively wash the entire exterior surface of a vehicle body.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

The washing machine of the example is 1. As shown in Figures 1 to 4, a running platform 1 is installed along and beside the tracks of a car wash.

It is attached to the front of the trolley 2 and the front of the same trolley 2, which has a flat front surface, and is operated by operating power (hydraulic pressure in the illustration).
A frame-type movable pedestal 3 that can be moved within the width of the trolley 2 by being driven by the frame, and a frame-type movable pedestal 3 whose base is horizontally supported by the pedestal and which can expand and contract in the radial direction by being driven by operating power (hydraulic force). A pantograph type variable length arm 4, the base of which is pivotally connected to a support shaft 5 vertically suspended at the tip of the variable length arm 4, and is swung in a desired direction by being driven by operating power (hydraulic force). A rotating arm 6 in the form of a yoke, a rotating shaft 7 vertically suspended at the tip of the arm and rotationally driven by power (hydraulic pressure), and a cylindrical bellows mounted on the rotating shaft 7. At 8,
and a brush 8 having a width that spans the entire height of the outer surface of the vehicle body B to be cleaned.

Note that some members shown in FIG. 4 (the figure is a power system diagram) are omitted from the structural drawings of FIGS. 1 to 3.

The specific structure of each part will be described below.

(a) Trolley 2 The trolley 2 includes an operation panel mounting surface 10 and a foot surface 11 for workers.
．． 12, etc. are formed, and the wheels 13 thereof are driven by the output of the engine E via a counter shaft 1.4 and a reduction gear 15.

In addition to the hydraulic piping system described later, a clean water motor pump P1 for cleaning, a generator G1 that supplies power to the same pump P, and a cooler C for cooling high-pressure oil are installed at appropriate locations on the trolley 2. The generator G is driven by the engine E, and the cooler C is supplied with cooling water.

Further, a hydraulic pump 16 and an oil tank 17 driven by the engine E are installed, and the pump 16 is provided with a return passage 18.

In addition, guide rails 19 are fixed in the form of a crosspiece at the top and bottom of the front of the truck 2, and a frame 3 is installed on the middle crosspiece 20.
The upper end base of the driving hydraulic cylinder 21 is pivotally supported, and the operating rod of the cylinder 21 is joined to the short arm 22a of an L-shaped bar 22 bearing the upper surface of the lower rail 19.

(b) Movable pedestal 3 The movable pedestal 3 has four corners - rails 19.
The base shaft 23 of the variable length arm 4 is attached to the carriage 2 by being inserted into the groove of the button 7, and the base shaft 23 of the variable length arm 4 is placed on the vertical line at the middle part in the width direction of the platform 3. It is freely supported.

Furthermore, the upper end of the long arm 22b of the lever 22 is engaged through a long hole in the middle part of the crosspiece 27, which is placed in the middle of the pedestal 3. In this case, a locking hydraulic cylinder 25 is mounted upward, and a locking pin 26 forming an operating rod of the cylinder 25 projects upward.

(e) Variable-length arm 4 The arm 4 has double vertical frames 30 and 31 that are integrally formed in parallel with the base shaft 23, and a yoke-shaped support frame 32 that bears the support shaft 5. It is formed by a link arm 33 that connects the frame 30 and the support frame 32, and the tip of the operating rod of the hydraulic cylinder 34 for driving the telescopic arm 4, which is attached to the lower end of the vertical frame 31, is connected to the link arm 33. The middle part of one of the arms is connected at the center.

A swing hydraulic motor 35 directly connected to the support shaft 5 is installed on the upper surface of the support frame 32.

Further, a turntable 24 is pivotally attached to the upper end of the base shaft 23, and lock holes 24 are bored at multiple locations (two locations in the figure) on the circumference of the table 24 near the outer periphery. The same circumferential line faces the lock pin 26.

(d) Swivel arm 6 A hydraulic motor 36 directly connected to the rotating shaft 7 is installed on the top surface of the swing arm 6 .

Next, the configuration of the hydraulic piping system will be explained with reference to FIG.

The high pressure oil discharged from the hydraulic pump 16 is filtered through the filter 40.
After passing through the cylinder and cooler C, it is divided into 5 systems: 3 cylinder systems: the pedestal cylinder 21, the telescopic arm cylinder 34, the button and lock cylinder 25, and the 2 motor system: the swing motor 35 and the brush motor 36. Although it is branched, each group is provided with a throttle valve 41 and operation valves 42 and 43, respectively, and a pressure reducing valve 44 is provided in the brush motor 36 system.

The washing machine of the embodiment is constructed as described above, and the operation and operation of the above-mentioned washing machine will now be explained.
An operation panel (not shown) installed on the mounting surface 10 of the truck 2 is equipped with handles and switches necessary for operating the engine E1, pump P1, cooler C, etc., and controlling the above-mentioned hydraulic equipment.

Therefore, by using these operating means, the operator on board the foot stage 11 or 12 can freely move the pedestal 3 and turn the turntable 24 by hand to lock the pointing direction of the variable length arm 40 to the desired position. move in the direction and
In addition to being locked by fitting the lock pin 26 into the lock hole 24a, the bending angle of the swing arm 6 relative to the variable length arm 4 can be freely set, and the rotation speed of the brush 80 can be freely adjusted. .

When cleaning the side surface of a vehicle body B such as a train, as shown in FIG. Direct the brush head diagonally forward, apply an appropriate pressure to the side of the car body to the brush brush 8, and in this state, rotate the brush 8 at an appropriate speed and let the trolley move on its own. For example, the side of the vehicle body can be cleaned easily and reliably.

When cleaning the joints of the car body, as shown in FIG. It is sufficient to extend and retract the variable length arm 4 while tilting it in the direction.Furthermore, when cleaning the front (or rear) of the vehicle body, the swing arm 6 can be moved in the direction a (t or direction b). In addition to tilting the arm 6 to accommodate obstacles and unevenness on the vehicle body surface,
The variable length arm 4 may be extended and contracted while adjusting the bending angle.

In order to store the brush 8 after cleaning, as shown in FIG.
By folding it all the way to the side, the brush 8 can be stored compactly.

In addition to cleaning with a brush, this washing machine can also be used to apply detergent and wash with water using the button and clean water spray.

As described above, according to the cleaning machine of the present invention, the arm of the self-propelled cart that extends the brush laterally is formed to have a variable length, and the short arm at the end of the extended arm that directly holds the brush is formed. Because it is formed so that it can be moved diagonally forward and backward, the entire exterior surface of the vehicle body can be easily cleaned without any manual effort, and any surface left unwashed due to unevenness on the vehicle body surface can be cleaned easily. This has the effect of improving the operability, labor saving, and safety of the washing machine.
