[Detailed description of the invention]

[0001]

Industrial Applicability The present invention relates to layance generated on a large-area concrete joint surface of a dam construction, a water purification plant, a sewage treatment plant, and the like, or a deposit on a wide pavement surface such as a road, a runway, and a sports ground. The present invention relates to a sprinkling vehicle for removing adhering matter, which is applied by applying high-pressure water injected from a nozzle.

[0002]

2. Description of the Related Art Conventionally, latencies generated on a concrete joint surface having a large area such as a dam construction, a water purification plant, a sewage treatment plant, and the like, or a deposit on a wide pavement surface such as a road, a runway, and a sports ground are removed. In this method, a worker had to use a hose provided with a nozzle for watering at the tip and wash it while walking with his hands. This type of work removes extraneous matter by spraying water from the nozzle, so the hose diameter becomes relatively large in order to secure a sufficient amount of water, and the water pressure sprayed from the nozzle is also large, suppressing the reaction to high-pressure injection. It took considerable effort.

[0003] Further, since such sprinkling removes deposits with high-pressure water jetted from a nozzle, it is necessary to efficiently apply the high-pressure jetting water to a sprinkling surface. However, the sprinkling surface is not only flat but also has an inclined surface everywhere, which makes it difficult to automate the sprinkling device for removing the deposits.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a nozzle capable of freely changing a water spray angle even on a water spray surface having various inclined surfaces. It is an object of the present invention to provide a watering vehicle for removing adhering matter, which is capable of efficiently removing adhering matter from a watering surface having an area with a small amount of labor.

[0005]

In order to solve the above-mentioned problems, a water sprinkling vehicle for removing deposits according to the present invention is provided with a post 3 which is rotatable about a vertical axis by a motor 2 on a traveling vehicle 1; A guide plate 4 is supported by a horizontal axis on the upper portion of the post 3 and the guide plate 4 is connected to a cylinder 4a connecting the post and the guide plate.

The arm 6 is movable by meshing with a pinion 9 that is rotated by a motor 8 fixed to a guide plate, and a fixed plate 10 is fixed vertically to one end surface of the arm 6, and the vertical direction of the fixed plate 10 is The movable plate 13 is slidably pivoted along
The movable plate 13 can be moved up and down by rotating a ball screw 14 whose upper and lower portions are held by the fixed plate along the fixed plate 10 by a motor 16 in a state in which a guide nut 15 fixed to the movable plate 13 is engaged. The actuator 2 is provided on the front surface of the movable plate 13.
A bracket 18 is fixedly mounted on a horizontal support shaft 17 which is rotated by the motor 4, and a pair of clamps 19, 19 are connected to the front end of the bracket 18 on both sides of the front end so as to be rotatable about the horizontal axis. The two connecting rods 2 each having a second pin joined to each of the clamps 19 at a position eccentric from the rotation center of the disk 21 rotating around the horizontal axis
Nozzles 1a, 21a are joined by pins, and nozzle pipes 23, 23 having nozzles 22, 22 attached to the lower ends of the clamps 19, 19, respectively, are vertically suspended in a freely variable height position, and the nozzles 19 are tightened by a handle 19a. The configuration is such that the pipes 23, 23 are fixed at predetermined positions.

[0006]

According to the above construction, an ideal nozzle injection state is always ensured in accordance with the inclination of the watering surface from which the deposits are to be removed or the surroundings. Therefore, the above configuration operates so as to vary the injection angles of the pair of nozzles 22, 22 in various ways. First, when the post 2 is rotated to a predetermined position by driving the motor 2 so that the arm 6 is directed in a direction perpendicular to the horizontal direction with respect to the forward direction of the traveling vehicle 1, the arm 6 hangs down from the head portion 30 of the arm 6. A pair of nozzles 22, 2
Numeral 2 forms a watering area that is double in front and rear with respect to the forward direction of the traveling vehicle 1. Then, the motor 20 is driven to continuously rotate the disk 21 to thereby eccentrically rotate the connecting pins 21b of the connecting rods 21a, 21a.
9 swings in the forward direction of the traveling vehicle 1 and clamps 19, 19
The pair of nozzles 22, 22 are oscillated through nozzle pipes 23, 23 vertically provided respectively.

The traveling surface of the traveling vehicle 1 is flat,
When the sprinkling surface is inclined back and forth along the forward direction, the actuator 24 takes a desired rotation angle to the bracket 18 so that the pair of nozzles 22 and 22 have a uniform height with respect to the inclined sprinkling surface. Can be included.

Further, a ball screw 14 is driven by a motor 16.
Is rotated, the movable plate 13 is guided by the guide nut 15 and moves in any of the upper and lower directions. As a result, the height of the nozzles 22 and 22 can be adjusted. As a result, the height of the nozzles 22 and 22 can be adjusted. Sprinkling range can be varied.

The arm 6 can be moved laterally by guide rollers 5, 5... The pinion 9 is rotated by a motor 8 in a predetermined direction so that the arm 6 meshes with the rack 7 to move the arm 6 in the lateral direction. As a result, the distance between the traveling vehicle 1 and the nozzles 22, 22 can be varied.

Further, when the water sprinkling surface is inclined in a direction orthogonal to the forward direction of the traveling vehicle 1, the inclination angle of the arm 6 is changed by the cylinder 4 so that the nozzles 22 and 22 with respect to the water sprinkling surface as described above. Can be applied vertically.

Further, even if there is any obstacle in the forward direction of the traveling vehicle 1, the horizontal direction of the arm 6 is changed by driving the motor 2 and rotating the post 3, so that the water spray range of the nozzles 22, 22 can be changed. Can be varied.

As described above, the water sprinkler for removing adhering matter according to the present invention has two nozzles in the forward direction of the traveling vehicle so that water sprinkling at the front position and water sprinkling at the rear position are doubled. By continuously swinging the pair of nozzles in the forward direction, the high-pressure water sprayed from the nozzles can be applied to the water spray surface at a continuously changing spray angle. As a result, the efficiency of removing adhering substances can be increased.

Further, by adjusting the height of the arm and the height of the nozzles, the distance between the pair of nozzles and the spray surface can be changed to change the injection range and the injection pressure.

Further, since the tilt angle of the nozzle with respect to the forward direction and the tilt angle of the arm with respect to the direction perpendicular to the forward direction can be adjusted, the spray pressure of the nozzle can be evenly controlled with respect to the tilt of the water spray surface in all directions. You can guess.

Furthermore, even when there is some obstacle in the forward direction of the traveling vehicle, for example, when there is a delta-shaped watering surface and the traveling vehicle cannot enter, the traveling vehicle is stopped in front of it and the arm is moved to the watering surface. It is possible to cope by pointing and extending the arm as described above.

As described above, the water sprinkler for removing deposits according to the present invention can sprinkle water over a large area without the need for labor by automatic water sprinkling by the vehicle, and can be controlled while the operator is on the vehicle. By doing so, the injection pressure of the nozzle fluctuates according to the inclination state of the watering surface and the surrounding conditions, and high-pressure injection pressure water can be applied from the front and rear double nozzles while continuously swinging on the watering surface Therefore, it is possible to efficiently remove deposits such as latencies or rubber scum on the sprinkling surface having a large area without requiring labor.
