Description

  The present invention relates to a road marking construction machine for marking a marking line on a pavement surface such as a road.

  In general, in the construction of markings such as lane markings on pavement surfaces such as roads, a dedicated road marking construction machine that can attach liquid or molten road marking material to the road surface with a predetermined width and film thickness is used Has been. There are two types of road marking construction machines, one that is mounted on a large vehicle and one that is pushed by hand. Usually, a vehicle-mounted one is used. Easy hand-push type can be installed more efficiently. However, when using a solvent-type road marking material that requires heating during construction, the construction machine is limited to a vehicle-mounted type, and construction efficiency in small-scale construction is not good. This is because the solvent-type road marking material is flammable, so the construction machine that is used by heating it must have a flammable prevention structure that clears the regulations of the Fire Service Act, etc. It is.

  However, since solvent-type road marking materials contain a large amount of volatile organic compounds (VOC) that cause photochemical air pollution, the amount of VOC has recently been increased by using water as a solvent for environmental considerations. Aqueous road marking materials with a drastic reduction have been developed, and their usage is increasing. Since this water-based road marking material is not flammable, unlike the solvent type, the construction machine does not require a flammability prevention structure even when heated and used (see, for example, Non-Patent Documents 1 and 2).

However, as described above, there is no structure for heating a liquid road marking material in a hand-held construction machine, so when using an aqueous road marking material that needs to be heated at the time of construction, a vehicle-mounted Construction work is carried out with a construction machine, and the low construction efficiency in small-scale construction has not been improved.

  An object of the present invention is to provide a hand-operated road marking construction machine that can be used by heating an aqueous road marking material.

  In order to solve the above-described problems, the road marking construction machine of the present invention has a construction in which a compact and simple mechanism capable of easily heating an aqueous road marking material is mounted on a construction machine body that can be manually pushed.

  Specifically, a tank for containing an aqueous road marking material, a water tank for immersing the tank, a burner for heating the road marking material in the tank via the water tank, and a cylinder for containing propane gas as fuel for the burner. It was mounted on a construction machine body equipped with wheels, and an aqueous road marking material heated by the burner while being moved on the road surface could be sprayed on the road surface.

  As described above, the road marking construction machine according to the present invention is a hand-held type equipped with a heating mechanism for an aqueous road marking material. Therefore, when a small-scale road marking is performed with an aqueous road marking material that requires heating. Construction efficiency can be significantly improved as compared with the prior art.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this road marking construction machine, as shown in FIG. 1, the construction machine main body 1 is a hand-held type having a handle 2 and three wheels 3, and an engine 4 having left and right front wheels 3 mounted on the construction machine main body 1. By driving with, it moves on the road surface at a low speed, and the handle 2 is operated manually to change the moving direction.

  As shown in FIGS. 2 and 3, the construction machine main body 1 includes a spray gun 5 that sprays an aqueous road marking material on the road surface, and beads that drop glass beads, which are reflective materials, onto the road marking material that adheres to the road surface. A spreader 6 is attached. The spray gun 5 and the bead spreader 6 can adjust the spray width of the road marking material and the amount of beads spread by operating the levers 7 and 8 attached to the handle 2, respectively. As an accessory of the construction machine main body 1, a night lighting lamp 9 is attached to the front of the main body 1, and a fire extinguisher 10 is provided below the handle 2.

  As shown in FIGS. 1 to 3, in addition to the engine 4, the construction machine main body 1 includes a cylindrical tank 11 into which a road marking material is placed, and heating for heating the road marking material in the tank 11. A mechanism 12, a pump 13 for sending road marking material from the tank 11 to the spray gun 5, a generator 14 for supplying electric power to the pump 13, etc., a bead tank 15 connected to the bead spreader 6, and a tachograph 16 are mounted. The tachograph 16 is connected to a disk-shaped encoder 17 pressed against the left front wheel 3, and records the speed of the construction machine detected by the encoder 17 for construction management.

  The heating mechanism 12 has a compact structure comprising a cylindrical water tank 18 in which the tank 11 is immersed, a burner 19 disposed immediately below the bottom of the water tank 18, and a cylinder 20 containing propane gas as fuel for the burner 19. Thus, the road marking material in the tank 11 can be easily heated by the burner 19 through the water tank 18. Here, the water tank 18 is interposed between the tank 11 and the burner 19 in order to make the temperature of the road marking material in the tank 11 more uniform and stabilize the workability by the flow of water in the water tank 18. It is.

  This road marking construction machine has the above-described configuration, and can spray a heated aqueous road marking material and spray glass beads while moving on the road surface. Therefore, in construction that performs small-scale road marking with water-based road marking that requires heating, the construction efficiency is greatly improved by using this construction machine compared to the conventional vehicle-mounted type. To do. In addition, the aqueous road marking material that can be used at room temperature can be appropriately heated to stabilize the workability.
