Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for spraying a cleaning liquid onto a contaminated object to be cleaned, such as a vehicle, and automatically wiping the object to be cleaned.

Generally, when cleaning various types of car bodies, a brush is applied while continuously discharging a cleaning liquid (in most cases, water is used), or a cleaning liquid is spouted from a nozzle and energized to spray the cleaning liquid onto the object to be cleaned. Cleaning is in progress.

By the way, in the former method, contaminated parts can be sufficiently cleaned, but it is difficult to wipe off parts with many protrusions with a brush, which requires manpower and time, and has the drawback that it may damage some objects to be cleaned. Well, the latter allows cleaning by remote control without touching the object to be cleaned, so it can be easily cleaned even if there are obstacles such as protrusions without damaging the surface of the object to be cleaned.

but.

The cleaning power is not as strong as wiping with a brush, and in order to increase the cleaning power, the water jet power must be increased. As a result, the object to be cleaned is subjected to strong surface pressure, making it unsuitable for cleaning aircraft bodies, for example, where this surface pressure is limited. There is a strong desire for a highly efficient cleaning device that does not require manual labor.

In view of the above-mentioned circumstances, the present invention has been developed as a cleaning device that automatically and efficiently wipes out contaminated parts of an object to be cleaned, which are sprayed with cleaning liquid, while jetting cleaning liquid with a relatively weak pressing force through remote control by an operator. The purpose of the invention is to provide a box-shaped frame frame in which a cleaning tool provided inside has a front opening protruding from the front opening, and supports the frame frame on the back side of the frame frame, an arm having a drive mechanism for raising and lowering the frame in the vertical direction, a drive mechanism for moving the frame forward and backward, and a drive mechanism for rotating the frame in the left and right directions; and an arm that is attached at predetermined positions on the opening edge of the frame at intervals, The cleaning apparatus is provided with three or more sensors that adjust the respective drive mechanisms to make the opening surface of the frame face the cleaning surface of the object to be cleaned and maintain a predetermined distance therebetween.

The present invention will be explained below with reference to the drawings.

A driver's cab 4 is attached to the rail 3 so as to be movable in the vertical direction. The operator's cab 4 houses an operating device for driving and adjusting the driving mechanism of each part of the cleaning device, and for driving and steering the trolley.

Further, the first arm C is pivoted to a bracket 5 provided at the tip of the support column B, is rotated in the vertical direction by a hydraulic cylinder 6, and is expanded and contracted by a built-in hydraulic cylinder (not shown) or the like. It is designed to be driven. The second arm D is rotatably attached to the tip of the first arm, is driven upward by a pinion gear mechanism (not shown) driven by a hydraulic motor, and is driven by a built-in hydraulic cylinder (not shown). (not shown).

In addition, the connection part with the bowl 3A lbE and the cleaning part F is connected to the second
Figure <a), (It is configured as shown in the top view and side view. That is, the bracket 7 is attached to the tip of the third arm E.) The base of the member 8 is attached to be rotatable in the vertical direction. The distal end of the connecting member 8 has a shape in which the base is displaced by 90 degrees, and is connected to a bracket 9 attached to the center of the back of the frame G of the cleaning section F so as to be rotatable in the left-right direction. Several ends of an elevating hydraulic cylinder 10 and an oscillating hydraulic cylinder 11 are rotatably provided on the back surfaces of the third γ-m E and the connecting member 8, and between the connecting member 8 and the frame G, respectively. The cleaning section F is driven upward and downward or swings in the left and right directions. In addition,
The length of the third arm E is such that the tip of the second arm D does not get in the way when the cleaning section F is lifted up.

The broken frame G has an almost box-like shape with its front side completely open, and a cleaning tool group F3 consisting of a cleaning tool F2 combined with a cleaning tool F1 described later opens the opening of the frame G. The cleaning section F is configured by storing the cleaning section 1 with the tip protruding.

The cleaning tool unit F1 is constructed as follows. That is, as shown in FIGS. 3(a) and 3(b), a flexible material such as raw rubber is made of a rainbow material, and the tip is cut in a predetermined length in the vertical direction to form a tufted shape 521a. The base of the tube 21, which has a large wall thickness and diameter, is connected to a tip spout 23 of a nozzle 22 that spouts a gas-liquid mixed flow.

The above nozzle 22 is constructed as follows. That is, a cleaning liquid introducing member 25 that is pumped by a pump (not shown) is screwed and fixed to one end of the rigid tube 24 of a predetermined length, and a cleaning liquid discharging member 270 is inserted through a pressure hose 26 or the like.
connected to the base.

The tip of this cleaning liquid discharge member 27 is connected to the gas-liquid mixed phase liquid discharge member 2.
The cleaning liquid discharge member 27 and the gas-liquid multiphase flow jetting member 28 are connected and fixed by a surrounding fixing member 30, and the gas-liquid multiphase flow jetting member 28 has a tip jet Rigid tube 24 with outlet 23 protruding
is fixed to the other end. In addition, holes 24a and 30a are bored in the rigid tube 24 and the fixing member 30 to introduce pressurized air from an air pressure feeder (not shown), and gas is drawn in from the gap 29 using the same principle as an aspirator. Thus, a gas-liquid multiphase flow is formed.

In addition, the cleaning tool F2 is shown in FIG. 4 (~, (b) is a side view,
As shown in the front view, the cleaning tools F1a are arranged in parallel in a staggered manner (equilateral triangle), facing in the same direction. This cleaning tool F2 has multiple rows on the vertical frame body 31.
These cleaning tools are attached to the rigid tube 24 of the nozzle 22 so as to be slidable in the front and rear directions.The vertical frame body 31 to which these cleaning tools are attached is attached at a predetermined interval as shown in the plan view of FIG. Multiple rows (three rows in the figure) are arranged, and cleaning tool group F
3 is formed and halved. This cleaning tool group F3 is movable in one direction within the frame G by the same distance as the spacing between the vertical frames 31 and 31, and is housed with the retube 21 protruding from the frame G. F2 is provided with a drive cylinder 32 that drives it in the front-rear direction, and the drive cylinder 32
is the sensor 33 provided in each cleaning tool F2.
It is designed to be expanded and contracted separately by the 0 command. Further, within the frame G, a transverse cylinder 34 is provided to move the vertical frame bodies 31 . . . from side to side.

Furthermore, pressurized collection pipes 35 and 36 for cleaning liquid and gas (air) are arranged on the inside of the back surface of the frame G, and each cleaning tool F2
It is connected to the cleaning liquid introduction member 25 and the hole 24a of the nozzle. The collecting pipes 35, 36u and the transverse hydraulic cylinders 34' allow them to move laterally in synchronization with the vertical frame 31. Cleaning liquid and air are pumped into the collector pipes 35 and 36 by pumps and pressure feeders (not shown), respectively.Furthermore, at the four corners of the frame G, projecting a predetermined size forward or openings are provided. Frame frame sensor 3 that retreats to the edge
7 is installed. When this sensor 37 is in an extended state, the tip of the sensor connects the telescopic mechanism (not shown) of the first arm C, the hydraulic cylinder 10 that raises and raises the cleaning section F, and the oscillating hydraulic cylinder 11 as shown in FIG. 6(a). r(b)
+ As shown in (c), the cleaning surface 39 of the object to be cleaned 39
The opening surface 38 of the frame G is adjusted so as to be in contact with a.
is made to face the cleaning surface 39a and maintained at a predetermined distance.

Next, the operation of the cleaning device configured as above will be explained.

First, drive the cart A, bring it close to the object to be cleaned 39, and move it to the column B.
, vertical rotation and contraction of the first arm C, upward rotation of the second arm D, expansion and contraction, and elevation and swing of the cleaning unit to bring the cleaning unit F closer to the surface to be cleaned 39a, and after cleaning the frame frame. G sensor 37 is extended, and the first
The extension and contraction mechanism of the arm C is used to raise, raise, and swing the cleaning tool F. The hydraulic cylinders 10 and 11 are placed under the command of the sensor 370, and three of the sensors 37 touch the cleaning surface 39a to clean the frame opening surface 38. facing the surface 39a,
and maintain a predetermined distance. Then, the sensor 37 automatically retracts, the cleaning tool F2 protrudes, and each sensor 33 of each cleaning tool F2 causes the sensor 37 to move as shown in FIG. 7% (a) and (b).
As shown in Fig. 3, each cleaning tool F2 stops when the trap detects the surface to be cleaned 39a, the cleaning liquid and air are fed under pressure, and the tube 21 becomes straight. to wipe away contaminated surfaces. At the same time, the transverse cylinders 34, 34' extend to move the vertical frame 31 a predetermined distance in the lateral direction, and when the movement is completed, the jetting of the cleaning liquid and air stops. During this time, the surface to be cleaned 39a is sequentially cleaned by the sensor 3.
3, the tuft 21a is held in position to wipe the contaminated surface. In this way, the surface to be cleaned that faces the opening surface of the frame G is wiped and cleaned. Next, the frame 4 is moved to the next contaminated surface and the same operation is repeated to sequentially perform wiping and cleaning. The above-mentioned cleaning is performed by a gas-liquid multiphase flow with a low specific gravity and the tufted portions 21a that roll due to the flow, so the surface pressure applied to the object to be cleaned is small.
It can accommodate aircraft etc. with sufficient margin.

There is no particular limit to the pressure for pumping the cleaning liquid and air as long as the tube 21 is linear and the cylindrical part rolls, but cleaning liquid = 10 ± 4 ky/cm 2, air: 5゛ ± 2 ky /
twr about 2 is preferable. The opening of the frame varies depending on the object to be cleaned, but in the case of a large jet aircraft etc., the opening of the frame is preferably about 3mm x 2mm, and the cleaning tool F2 is arranged vertically and horizontally. This can be accommodated by increasing or decreasing the number of stages.

When cleaning a wide surface with large waves, three frame sensors protruding by a predetermined distance are appropriately arranged on the edge of the frame G, and the drive mechanism of the arm is adjusted to clean the cleaning surface 39a in a macroscopic manner. The opening surfaces 38 of the frame frame G are arranged to face each other at a predetermined interval, and a cleaning tool F2 that moves forward and backward while capturing the cleaning surface microscopically is provided in the frame G, and the cleaning section F is moved between the cleaning section F and the second arm D. It can also be cleaned by gradually moving it by expanding and contracting it. At this time, sensor 3
It is preferable that the tip position of No. 7 is between the positions of the tip tufted portion 21a of the cleaning tool F2 which moves forward and backward. This method can be carried out in good condition by adjusting and fixing the protruding dimension of the sensor shown in FIG. 6 In addition, for a flat cleaning surface, place the tip of the cleaning tool F2 at approximately the same LV as the tip position of the sensor 37.
C may be fixed.

In the above description, the rotating portion is driven by a hydraulic cylinder or a pinion gear, but a normal rotary actuator may also be used as appropriate.

As mentioned above, the cleaning device according to the present invention can easily and efficiently wipe and clean huge large aircrafts, etc. that have limited surface pressure, so that the cleaning work that requires manpower and time can be greatly reduced. , the benefits to maintenance-related work are extremely large.
