Description

[Detailed Description of the Invention] The present invention relates to a concrete pouring surface cleaning vehicle device, in other words, a cleaning device equipped with a cleaning suction tool to be attached to a construction vehicle to form a cleaning vehicle.

When constructing a dam, etc., the amount of concrete to be poured is large, so it cannot be poured all at once and must be poured several times. Concrete cannot be poured until impurities have been removed with a brush or cleaned with water from a high-pressure nozzle, and in the past, cleaning the concrete pouring surface required a great deal of time and expense.

The present invention was proposed in order to solve the above-mentioned problems, and its purpose is to completely clean the hardened concrete pouring surface, to completely collect the cleaning liquid by suction, and to make it inexpensive. The goal is to provide products that can be manufactured in a timely manner.

In order to achieve the above-mentioned object, the present invention utilizes a conventionally known construction vehicle and attaches a cleaning tool to it to construct a cleaning vehicle.

According to the present invention, an injection device having a plurality of nozzles that injects high-pressure water onto a concrete placement surface, and a suction device that sucks and collects the water injected from the injection device are separated, and these injection devices and suction Each device is equipped with a link mechanism that allows it to move forward, backward, left, and right while maintaining a horizontal position on the road surface regardless of the vehicle.The suction device has a substantially triangular planar shape, and a rubber plate is attached to the lower end of the side facing the injection device. diagonally installed, and the other 2
A brush is provided on the side, and the suction device is provided at a position away from the injection device toward the vehicle.

In the present invention, when performing this work, the concrete pouring surface is first scraped off with a brush or the like using a preceding device, and then the device implementing the present invention cleans the concrete pouring surface by sucking up the scraped debris. be.

Since the brushes are placed closely on the two sides of the suction device, the inside of the triangle surrounded by the rubber plate and the brushes is cut off from the atmosphere, resulting in a relatively negative pressure and the suction easy to be

The rubber plate is slightly separated from the concrete surface, and the chips enter the triangular suction device from under the rubber plate and are sucked up.

At that time, high-pressure water peels off and removes scale from the concrete.

The brush retains the shavings of the cleaned surface within the triangle and also serves to clean the concrete surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

The concrete pouring surface cleaning vehicle device (hereinafter simply referred to as the device) according to the present invention is installed and used on a construction vehicle as shown in the figure, but the configuration of the vehicle itself is well known to those skilled in the art. Therefore, I will not give a detailed explanation.

However, since the vehicle A has a parallel link mechanism B, a triangular member B', a parallel link mechanism B'', etc., when these are driven by a cylinder/piston mechanism (not shown), the frame G moves in the longitudinal direction relative to the vehicle A. It is supposed to be done.

The device E, as schematically shown in FIGS. 1 and 2, consists of an injection device 6 and a suction device 5, which are mounted on the frame G or the auxiliary frame 2, as described below.

That is, the auxiliary frame 2 has a substantially triangular planar shape as shown in FIG.
It is pivoted to.

The frame G is attached to the tip of the parallel link mechanism B// of the vehicle A with pins 10 and 11.

The slide shaft 21 is connected to a receiver 22 as shown in FIG.
It is supported so as to be movable in the left and right directions with respect to the vehicle A, and its movement is driven by a sliding hydraulic cylinder device 7, which is not shown in detail.

The injection device 6 is attached to the auxiliary frame 2 constructed in this way, but the pressure water pipe 61 forming the injection device is cut off in part and is not continuous, as shown in FIG. The pressure wood pipe has a substantially trapezoidal shape, and is provided with a plurality of injection nozzles 62 facing the concrete surface C and inward of the trapezoid.

Further, this pressure water pipe 61 is connected to a hose 63 to a high pressure source (not shown) mounted on a towing vehicle being towed by vehicle A.
are connected by

As shown clearly in FIGS. 2 and 3, the suction device 5 has a substantially triangular planar shape, and a rubber plate 52 is slightly attached to the concrete surface C at the lower edge of the side 51 facing the injection device 6. The brushes 54 are disposed diagonally so as to be in sufficient contact with each other with a gap, and brushes 54 are vertically disposed at the lower end edges of the other two sides 53 and 53.

That is, the rubber plate 52 extends in the width direction at a portion corresponding to the left long side of the triangular suction device 5 in FIGS. 2 and 3, and the rubber plate 52 is provided at a portion corresponding to the right short side of the triangular suction device 5. A brush 54 is vertically provided along the short side in a direction diagonal to the width direction.

Therefore, the triangular suction device 5 is surrounded by a rubber plate 52 at the front and by a brush 54 at the rear.

The end 55 of this suction device is connected to a hose 56 that is connected to a suction source (not shown).

Further, the suction device 5 is attached to the auxiliary frame 2 by a parallel link 57, as shown in FIG. 3, so that the lower end of the brush 54 of the suction device 5 always contacts the concrete surface C uniformly.

The lower end of the rubber plate 52 is provided slightly away from the concrete surface C.

Since the device according to the present invention is configured as described above,
When using it, the parallel linkage mechanism B/
The device E is attached to the tip of / and moved to the required location for cleaning work.

The concrete surface C is efficiently cleaned by the high-pressure water jetted from the nozzle 62 of the jetting device 6, and the cleaning water containing foreign matter such as sand is sent to the triangular suction device 5 surrounded by the rubber plate 52 and the brush 54. It is suctioned and transported from the inside by a hose 56 to a suction source mounted on a tractor.

It is also effective to equip the tow vehicle with a filtration device, as the water used for washing can be used repeatedly.

That is, during cleaning work, dirt and debris from the concrete surface C that has been previously scraped off by another device is sucked together with cleaning water by the suction device 5, but since the rubber plate 52 is used at that time, the suction device 5 and the concrete surface Since the brush 54 is sealed with a small gap between the brush 54 and the brush 54, and the brush 54 is densely flocked, the inside is sealed and the suction force is increased.

Therefore, since the suction air is sucked from the lower end of the rubber plate 52, the suction effect of dirt and cleaning water can be enhanced.

Further, since the rubber plate 52 is provided obliquely, the resistance during running can be reduced.

The cleaning work proceeds as described above, but when cleaning every corner of the concrete surface C, the device is moved forward and backward relative to the vehicle using the parallel link mechanisms B and B'' without moving the vehicle A each time. By moving the slide shaft 21 and the slide hydraulic cylinder device 7, the slide shaft 21 and the slide hydraulic cylinder device 7 can be used to move the slide shaft 21 and the slide hydraulic cylinder device 7.

Further, since the suction device 5 is attached to the auxiliary frame 2 by a parallel link mechanism 57, it can move up and down while maintaining a horizontal posture.

Therefore, it can adapt to the unevenness of the concrete surface C.

Furthermore, the device according to the present invention is attached to a vehicle and used when necessary, and when cleaning is not being performed, the expensive vehicle can be used for its original purpose such as construction work.

In particular, in the present invention, the concrete pouring surface is first cleaned using a spraying device, which can be suctioned as the vehicle advances, and the concrete can be smoothed with a brush.

Further, since the suction device and the injection device are attached using a link mechanism, it is easy to attach and detach the device to the vehicle, and the posture and position can be easily controlled.

When implementing this invention, the power can be obtained from a tow truck dedicated to cleaning, and by simply installing device E on vehicle A,
Therefore, vehicle A can be made versatile.
