Abstract

The device for applying paint to slopes is intended mainly for spraying the slopes of water tanks, canals, etc. sealed with asphalt concrete. On the chassis consisting of fixed and steerable wheels, there is a supporting frame equipped with a suspension and a handling platform and a steering wheel. On the supporting frame there is also a motor connected via a drive chain to the pump of the spraying circuit, consisting of a tank for the paint, a pipe distribution with a cleaning filter, a safety valve and control valves. The spraying circuit is connected through the spray filter to the spraying pipe and nozzles. The pump is also part of the flushing circuit consisting of a tank for flushing fluid and a flushing pipe distribution, connected via shut-off valves to the spraying circuit and to the spraying pipe with nozzles.

Description

The invention relates to a device for spraying on sealed slopes of hydraulic structures.

In water engineering, it is necessary to apply various coatings to prevent aging of the asphalt, perfect sealing of the surface to increase its waterproofness (net) with a reflective coating to prevent the influence of the infrared component of solar radiation, especially on slopes facing to south. Spraying kits consisting of a compressor connected by a pressure hose to a hand-held spray gun operated by a worker moving on a slope were most commonly used to apply paint to slopes of smaller area. The operator was in direct contact with the spraying agent, whose poisonous diluents limited the working time. Since in practice these are slopes with a large area of several hundred thousand square meters, a number of mechanized devices have been developed for sealing slopes of water reservoirs. Spraying devices are also known for application to sealed surfaces in flat terrain. However, the disadvantage of the known devices is that their fusing pads become sticky and become less usable due to the drying of the diluent, since they are generally treated with a longer time interval.

The above-mentioned drawbacks are eliminated by a slope coating system consisting of a fixed-wheel and steerable wheels chassis on which a tethered frame fitted with a hitch and a handling platform β steering wheel is mounted and on which a motor is connected via a chain to a sprinkler pump. a circuit consisting of a paint tank, a pipe system with a cleaning filter, a safety valve and control valves, the spraying circuit being connected via a filter to the nozzle spraying tube,

2 that the pump is also part of a flushing circuit consisting of a flushing liquid tank and a flushing pipe connected via shut-off valves to the spray circuit and to the blast sprayer pipe.

The advantage of the proposed solution is high labor productivity and its acceleration, because the spraying is carried out in strips three to five meters or more, by more uniform application of the paint. Work safety will be increased, workers' labor will be eliminated and their working conditions improved, in particular by reducing the direct influence of toxic solvents on their health. The functional part of the device can be blocked at any time or prevented by starting the flushing circuit. Another advantage of the device is that it can fill its tanks with paint and flushing liquid directly from the tanks via its own pump.

Example

The slope application system consists of a chassis consisting of fixed wheels 1 and steerable wheels 2, on which a support frame 3 provided with a hinge 4 and a handling platform 5 with a steering wheel 6 is supported, on which a motor 2 connected via a drive chain 8 with a spray circuit pump 9 consisting of a paint tank 11, a pipe 12 8 through a purification filter 13, a β safety valve 14 and control valves 15, the spray circuit 10 being connected via a spray filter 16 to a spray tube 17 s The pump 9 is also part of a flushing circuit 18 consisting of a flushing liquid tank 30 and a flushing pipe 21 connected via shut-off valves 22 to the spraying circuit 10 and to the spraying tube 17 with the nozzles 18 '.

The device can also be used for spraying slopes with other liquids, emulsions or suspensions, for example herbicide solutions and the like.
