Technical Field

The invention relates to road marking equipment that allows solvent, water, mastic, and silicone- based paints with a density of up to 2.2 g/cm ³ and materials of a maximum of 25 L per minute to be sprayed (spraying) up to 230 bar pressure without any need for pulverization.

State of Art

The road marking paint is specifically produced to be used for traffic markings. The road marking paints are designed to be last on the place of application thanks to their special components and produced in a manner not easily worn and enabling superiority of visibility. They are produced with different formulas such as rubber-modified, alkyd-based, MMA acrylic-based, and water-based. The road marking paint is used for horizontal and vertical traffic marking in open and closed areas. They have various kinds such as single-component road marking paints, two-component road marking paints, three-component road marking paints, and thermoplastic road marking paints Kinds of application for the road marking paints differ in accordance with the types of production. Most commonly used cold road paints (single-component marking paints) are best applied airless (with an airless or pneumatic machine), or alternatively with a brush or roller brush.

The pumps used in the present systems provide transmission by the motion of the piston in the seals placed along the sleeve, thereby creating a vacuum, then closing the suction path of the steel ball on the line, thereby pressurizing the material. In uninterrupted applications, the seals are impaired due to the heat generated by the friction in the internal structure of the pump and the efficiency gradually decreases after certain service life. Since the currently used pumps are of foreign origin, both cost and deadline are required for the equipment and parts to be supplied for maintenance/repair. These pumps can be used in the application of liquid or liquid-solid materials up to a density of 1.6 g/cm ³ . Using materials exceeding this value will damage the equipment. For currently used pumps, the hydraulic-material pressure ratio supports up to 1 : 1.10.

The invention relates to road marking equipment that allows solvent, water, mastic, and silicone- based paints with a density of up to 2.2 g/cm ³ and materials of a maximum of 25 L per minute to be sprayed (spraying) up to 230 bar pressure without any need for pulverization.

The hydraulic oil at high pressure, with the hydraulic oil pump located in the hydraulic engine (1 ) driven by the diesel engine, is transmitted to the hydraulic body of the pump (2) and actuates the piston thanks to the hydraulic drive shaft (4). The hydraulic piston, which moves up and down, actuates the paint pump drive shaft (9) and the spoon (8) thanks to the intermediate box connection (5) connecting the hydraulic engine with the paint pump. Thus, the paint is sucked by the pump by vacuuming from the outlet of the cold paint tank, which is manufactured for use without pressure and is transferred to the paint pump with the help of a spoon from the raw material inlet of the pump. The material present inside the pump spoon (8) is transferred to the inner portion of the pump during the motion. The hydraulic engine lower body (3) prevents the oil inside the hydraulic body (2) from coming out during application.

There is a varying pressure ratio in the hydraulic engine (1 ) portion and the paint pump portion. When the hydraulic piston drive shaft (4) positioned in the lower and upper pump bodies (6, 7) inside the hydraulic body (2) transfers power to the pump piston a certain number of times per minute, the suction-compression process takes place and the system performs the application process by keeping the paint ready at the application point. Said shaft (4) moves in a linear direction with the hydraulic pressure line in order to realize the suction-compression function of the paint pump. By means of the pump drive shaft (9) coupled to the piston drive shaft (4), suctioncompression motions are performed and the transfer of cold paint to the paint tank is ensured without an application of pressure.

This mechanical motion is repeated by the hydraulic engine (1) 40-50 times per minute, thereby forming a pressure line. 10
