Abstract

PURPOSE:To improve cleaning efficiency by providing the tip of a movable truck with a rotatable vertical shaft, and laterally providing its lower end with a nozzle arm having a plurality of downward cleaning nozzles, and jetting high temperature pressurized cleaning water from the cleaning nozzle toward a road surface. CONSTITUTION:A movable truck 1 is run in a crossing direction to a runway, and a motor 2 is started to rotate a nozzle arm 7 through a rotary shaft 5. Next, high temperature pressurized water supplied from a boiler and a pump is jetted through a nozzle 8 under the pressure of about 50 to 400kg/cm<2>. In this case, the high temperature pressurized water is jetted in a belt-shaped pattern from the slit-shaped nozzle of the nozzle 8, and injection is carried out in parallel to the grouping groove of the runway, and rubber or the like broiledly attached onto a road surface is softened under high temperature and stripped off by synergetic effect with injection pressure. In addition, the shaft 5 is moved up and down to adjust a distance between the nozzle 8 and the road surface to the optimum state. Thus the rubber or the like adhering to the road surface can be effectively removed and cleaned without damaging a paved surface.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing and cleaning rubber etc. on a pavement surface used for cleaning a runway or other intersections on an airfield, a road surface having fine grooves or irregularities such as tile pavement.

[0002]

2. Description of the Related Art Conventionally, a grooved groove A is horizontally provided on a runway pavement of an airfield as shown in FIG. In some cases, the resistance may be significantly reduced and the safe operation may be hindered. To remove these, direct jet cleaning with high pressure water, for example, 500 to 700 kg / cm ^2, was performed.

[0003]

However, the above-mentioned cleaning method using high-pressure water has a problem that the asphalt on the pavement surface is destroyed.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a device for removing and cleaning rubber and the like on a pavement surface, which is capable of efficiently removing attached rubber and the like without damaging the pavement surface.

[0005]

In order to achieve the above object, the present invention is directed to a front casing projecting forward from a main body of a moving carriage having a built-in drive mechanism, in which a rotary shaft rotated by the drive mechanism is vertical. And a nozzle arm having one or more cleaning nozzles on its lower surface is laterally provided on the lower end of the rotary shaft,
It is characterized in that a specific high temperature and high pressure cleaning water is jetted from the cleaning nozzle.

[0006]

With the driving mechanism rotating the nozzle arm through the rotary shaft, a specific high temperature and high pressure water is sprayed onto the pavement surface from the cleaning nozzle to move the movable carriage to clean the pavement surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a movable carriage, which is a box-shaped main body 1a and bolts 1b ... 1b fitted in vertical slots 1c formed in the main body 1a so that the main body 1a is fixed to the main body 1a. A driving mechanism including a rectangular parallelepiped front casing 1c screwed so as to be movable in the vertical direction, and a motor 2 in the main body 1a, and a reduction mechanism 2b transmitted by the motor 2 and a chain 2a. 3 was built in, and a suction type dust collecting device 4 was attached to the rear surface, and the suction port 4b of the suction pipe 4a faced the pavement surface.

Further, the front casing 1c is provided with a cylindrical rotary shaft 5 pivotally supported by bearings 1e and 1e provided on the angle 1d, and the rotary shaft 5 is a sprocket provided on the speed reduction mechanism 2b. 3a and a sprocket 5b and a chain 5c which are engaged with a key groove 5a of the rotating shaft 5 and are vertically movable so as to be adjustable, and a rotary joint 6 is connected to an upper end portion of the rotating shaft 5. High-temperature high-pressure washing water from a boiler device and a pump device (not shown) is supplied by a flexible pipe 6a.

Reference numeral 7 denotes a nozzle arm. The nozzle arm 7 is composed of a rectangular tube whose both end surfaces are closed. An intermediate portion 7a of the nozzle arm 7 is connected to the lower end of the rotary shaft 5 so that high-temperature high-pressure washing water can be obtained. Flows in.

Reference numeral 8 denotes a cleaning nozzle, which is fixed to the lower surface of the nozzle arm 7 and has an injection port 8a as shown in FIG.
Are formed in a slit shape. The nozzle arm 7
A large number of through holes are formed in the lower surface of the nozzle, and if necessary, a plurality of cleaning nozzles 8 are fitted in these holes, and blind plugs are fitted in the remaining holes.

Reference numeral 9 indicates a covered cylinder for preventing water splashing, the covered cylinder 9 is fixed to the front casing 1c of the movable carriage 1, and a sheet made of vinyl chloride or the like is attached to the lower end edge of the covered cylinder 9. 9a is hanging.

Reference numeral 10 is a caster and 11 is a handle.

Next, the operation of the above embodiment will be described.

In the runway, an asphalt B is usually laid on concrete C, and a grooved groove A is engraved in the asphalt B at right angles to the traveling direction of the airplane. The rubber of the tire is seized on the surface. In the case of cleaning this rubber, when the cleaning device is made to run transversely to the runway and the motor 2 is started, the rotation shaft 5 is moved by the sprocket 3a, the chain 5c, and the sprocket 5b via the reduction mechanism 2b.
And the nozzle arm 7 also rotates due to the joint action of the rotary joint 6.

Next, high-temperature high-pressure water is supplied to the pipe 6a by a boiler device and a pump device (not shown), and sprayed from the cleaning nozzle 8 at a pressure of 50 to 400 kg / cm ² .

The jetted high-temperature water is jetted in a strip shape from the slit-shaped jet port 8a of the nozzle 8 and is jetted in parallel with the grooving groove A, so that the seized rubber which is difficult to clean is softened by the temperature of the high-temperature water. Then, the rubber is separated by the synergistic effect with the parallel injection pressure, and the rubber is collected by the dust collector 4 by cleaning without damaging the asphalt surface.

The rotary shaft 5 has a long hole 1c in the main body 1a.
1b can be moved vertically by the bolts 1b ... And the covered cylinder 9 for preventing water splashing prevents water and rubber pieces from splashing.

Although the nozzle 8 is fixed to the nozzle arm 7 in the above embodiment, the groove 8 and the ejection port 8a are opposed to each other in parallel by rotating the nozzle 8 by a gear or a belt. The cleaning effect can be further improved by increasing the number of times.

[0020]

As described above, according to the present invention, while the nozzle arm is rotated by the drive mechanism via the rotary shaft, a specific high temperature and high pressure water is sprayed from the cleaning nozzle onto the pavement surface to move the movable carriage. I decided to clean the pavement surface,
It has the effect of efficiently removing the adhered rubber and the like without damaging the pavement surface.
