TECHNICAL FIELD

[0001] The utility model relates to road marking technical field, specifically, relate to a road marking vehicle. BACKGROUND

[0002] Road marking operation refers to the work of drawing and coating various types of signs on the road surface, which aims to provide clear and explicit traffic guidance information for road users. These markings cover a variety of types, the common ones are lane demarcation lines, such as white dashed lines used to separate different lanes for driving in the same direction, allowing vehicles to travel in an orderly manner; there are also pedestrian crossing lines, usually white zebra crossings, which attract attention and indicate the area for pedestrians to cross the street, ensuring the safety of pedestrians crossing the street. In addition, such as road edge lines are used to define the road range, allowing drivers to clearly know the driving boundary; and the guide arrows at the intersection accurately guide the driving direction of vehicles turning, straight driving, etc.

[0003] In the process of road marking operation, in the past, it is mostly dependent on manual brushing tools, and the construction personnel need to bend down for a long time, according to the established traffic planning standard, to apply paint on the road surface stroke by stroke, which is low in efficiency and high in labor intensity. The existing marking operation is set in the transportation process, and the container containing the marking liquid has poor stability, which is easy to cause displacement or even overturning of the container due to vehicle bumping and shaking, not only affecting the normal supply of the marking liquid, but also possibly causing damage to the equipment, increasing the maintenance cost and operation risk. Moreover, the traditional equipment is not accurate enough in controlling the spraying range during marking, which is easy to cause splashing of the marking liquid and pollution of the surrounding environment.

[0004] This is a problem worth discussing. INVENTION CONTENTS

[0029] The cylindrical block 22 is fixedly connected to a threaded rod, and the threaded rod is threadedly connected to the center of one end of the cylinder 19.

[0030] Furthermore, the gap between the cylindrical block 22 and the cylinder 19 is large enough to accommodate the limiting rope 101 wrapped around the cylindrical block 22 two to three times.

[0031] The box 1 has a liquid inlet, through which liquid pigments can be injected into the box 1, and the liquid pigments can have different colors.

[0032] In this embodiment, after the limiting rope 101 is wrapped around the middle of the box body 1, the two ends of the limiting rope 101 are respectively passed through the outer end round hole 21 of the protruding block 18, and then the two ends of the limiting rope 101 are respectively passed through the opening 20 and the corresponding through hole on the cylinder 19. The threaded rod is rotated to drive the cylindrical block 22 to rotate, and the cylindrical block 22 drives the limiting rope 101 to rotate. The limiting rope 101 rotates and wraps around the cylindrical block 22. At this time, the screw 23 is tightened, the cylindrical block 22 does not move, and the limiting rope 101 achieves the limitation of the box body 1.

[0033] A limiting rod 16 is slidably disposed inside the sleeve 14. A handle 17 is fixed on both sides of the upper end of the limiting rod 16. The sleeve 14 is threadedly connected to the limiting rod 16 with a second set screw 15, which can hold the limiting rod 16 in place.

[0034] In this embodiment, loosening the second set screw 15 allows the moving limit rod 16 to drive the handle 17 to rise and fall, while tightening the second set screw 15 can limit the position of the limit rod 16.

[0035] The liquid tank is connected to a liquid outlet assembly, which includes an air inlet pipe 2 connected to the upper part of one side of the liquid tank. A valve is provided on the air inlet pipe 2. The air inlet pipe 2 is also connected to an air pump 11. The air pump 11 is fixed inside the housing 131. The housing 131 is fixed to the lower side of the support frame 4. The lower side of the liquid tank is connected to a spray pipe 9 through a liquid outlet pipe 3. The spray pipe 9 is fixed to the center of the other end of the support frame 4. A nozzle 10 is fixedly provided at the lower end of the spray pipe 9.

[0036] In this embodiment, the air pump 11 is started, and the air pump 11 fills the liquid tank with air. Under pressure, the liquid is discharged from the liquid outlet pipe 3 and enters the nozzle 9, and then sprayed out from the nozzle 10 to achieve marking.

[0037] The nozzle 10 is provided with anti-splash components on both sides. The anti-splash components include baffles 8. A limiting ring 7 is fixedly provided on the upper side of the baffles 8.

[0040] In this embodiment, the first set screw 6 can limit the position of the limiting ring 7, and loosening the set screw can adjust the position of the limiting ring 7.

[0041] The support frame 4 is equipped with wheels 5 at its four corners.

[0042] In this embodiment, pushing the handle 17 can move the support frame 4, and the rotation of the wheel 5 assists in the movement of the support frame 4.

[0043] A storage battery 12 is disposed inside the outer casing 131, and the storage battery 12 is electrically connected to the air pump 11.

[0044] In this embodiment, the storage battery 12 supplies power to the air pump 11.

[0045] In use, the limiting rope 101 is wrapped around the middle of the box 1, and the two ends of the limiting rope 101 are passed through the outer end round hole 21 of the protruding block 18 respectively. Then, the two ends of the limiting rope 101 are passed through the opening 20 and the corresponding through hole on the cylinder 19 respectively. The threaded rod is rotated to drive the cylindrical block 22 to rotate, so that the cylindrical block 22 drives the limiting rope 101 to rotate. The limiting rope 101 rotates and wraps around the cylindrical block 22 until the screw 23 is tightened. At this time, the cylindrical block 22 does not move, and the limiting rope 101 achieves stable limiting of the box 1.

[0046] According to the road width, loosen the first set screw 6, and move the baffle 8 along the crossbar of the support frame 4 to a suitable position through the limit ring 7. Then tighten the first set screw 6 to fix the baffle 8 to prevent the marking liquid from splashing. Push the handle 17, and move the support frame 4 by rotating the wheel 5. At the position where marking is required, start the air pump 11 and open the valve on the air inlet pipe 2. The air pump 11 fills the liquid tank with air. Under pressure, the liquid is discharged from the liquid outlet pipe 3 into the nozzle 9, and then sprayed out from the nozzle 10 to start road marking until the marking is completed.
