Description

Technical Field

[0002] After the road is built, there are no road signs on the road surface, such as road dividing lines and driving direction lines, so the staff will use road marking machines to mark the newly built roads, drawing dividing lines, arrow lines and other indicating lines.

[0003] At present, most road markings are done with road marking machines. Although there are automatic road marking machines, for current engineering teams, most of the work is done with manually controlled road marking machines, which are manually pushed by staff to move the road marking machines. For road markings, since the road marking machines are equipped with movable rollers, skilled staff can control the road marking machines to move in a straight line and spray straight marking lines based on their work experience. However, for less experienced staff, when pushing the road marking machine to move, it is easy to rotate the movable wheel, causing the road marking machine to deviate, and then it is impossible to spray a straight line effect, affecting the spraying effect of the road markings. Therefore, a moving mechanism for a road marking machine is proposed to solve this problem. Utility Model Content

[0024] Example

[0025] Reference Figure 1-Figure 4 The utility model provides a technical solution: a mobile mechanism of a road marking machine, including a base 1 and a mobile assembly 3, a driven wheel 2 is installed at the bottom of the base 1, the mobile assembly 3 includes a mobile wheel 31, a roller seat 311 is movably installed at the bottom of the base 1, and the mobile wheel 31 is installed at the inner side of the roller seat 311. The base 1 is internally rotatably connected to a rotating shaft 321, one end of the rotating shaft 321 is fixedly connected to a limiting plate 32, and one end of the roller seat 311 and the rotating shaft 321 are respectively fixedly installed with a first pulley 33, and the two first pulleys 33 are connected through a first belt 331.

[0026] In a preferred embodiment, a circular hole 4 is provided on the outer surface of the limiting plate 32, and a threaded hole 5 is provided on the outer side surface of the base 1. A screw 6 is provided inside the circular hole 4, and the screw 6 is threadedly connected to the threaded hole 5. When the device is not in use, there is no need to limit the moving wheel 31. When the device is transported, the limiting plate 32 may shake at will and cause damage. Therefore, a circular hole 4 is provided on the limiting plate 32, and a threaded hole 5 is provided on the outer surface of the base 1. The limiting plate 32 can be stably installed on the base 1 by the screw 6, so that the limiting plate 32 can be protected.

[0027] In a preferred embodiment, the moving wheel 31 is rotatably connected to the inside of the roller seat 311, the outer surface of the roller seat 311 is flush with the outer surface of the base 1, and the limit plate 32 is slidably connected to the outer surface of the roller seat 311. Two limit plates 32 are arranged on the outside of one moving wheel 31. When marking the road, in order to ensure that the marking line is straight, the present device limits the rolling moving wheel 31. In order to improve the limiting effect, two limit plates 32 are installed on the outside of one moving wheel 31. The moving wheel 31 can roll stably and straightly under the clamping of the two limit plates 32, ensuring that the marking line is straight and meeting the requirements of use.

[0028] In a preferred embodiment, the upper surface of the base 1 is fixedly connected to a liquid storage tank 7, a pumping machine 8 is fixedly installed at the bottom of the liquid storage tank 7, a round tube is fixedly installed at the liquid outlet end of the pumping machine 8, a nozzle 9 is fixedly installed at one end of the round tube, and a push rod 10 is fixedly connected to the upper surface of the base 1. To facilitate spraying marking lines, the spray material is stored inside the liquid storage tank 7. Since it is liquid, it is sprayed out by extracting it with the pumping machine 8, and the spray liquid is directly sprayed toward the ground, which will form marking lines on the ground.

[0029] After the spray liquid is sprayed out from the inside of the liquid pump 8, not only the spray liquid will be sprayed out, but also gas will be generated. These gases are particles of the spray liquid. Once excessively inhaled into the human body, they will cause harm to the human body. Therefore, in order to solve this problem, the device is equipped with a dust suction mechanism 11 on the inner side of the base 1. The dust suction mechanism 11 includes a vacuum pump 111, an air intake bin 112 and a drive shaft 113. The first gear 12 is fixedly installed on the outside of the rotating shaft 321. The first gear 12 is meshed and connected to the second gear 13. The second gear 13 is fixedly installed on the drive shaft 113. Externally, the driving shaft 113 is rotatably connected to the base 1, and the upper end of the driving shaft 113 is fixedly installed with a main driving wheel 14, which is meshed with a secondary driving wheel 15, and the secondary driving wheel 15 is sleeved on the outside of the nozzle 9 and rotatably connected to the base 1, and the outer surface of the secondary driving wheel 15 is fixedly connected to the arc plate 16, and the outside of the arc plate 16 is fixedly connected to the vacuum pump 111, and the air inlet end of the vacuum pump 111 is fixedly connected to a connecting pipe, and one end of the connecting pipe is fixedly connected to an air inlet bin 112, and the air inlet bin 112 is stably installed on the inner side of the arc plate 16.

[0030] During operation, by pushing the device to move, the moving wheel 31 rolls on the ground, and drives the rotating shaft 321 to rotate. Through the meshing between the two gears, the driving shaft 113 rotates, and then drives the main driving wheel 14 to rotate. The main driving wheel 14 drives the auxiliary driving wheel 15 to rotate, so that the arc plate 16 can rotate around the outside of the nozzle 9. At the same time, the vacuum pump 111 is turned on to absorb the gas, effectively preventing it from being inhaled into the body of the staff, thereby ensuring the safety of the personnel.

[0031] Specifically, the working process or working principle of a mobile mechanism of a road marking machine is as follows: currently, most road markings are done using road marking machines. Although there are automatic road marking machines, for current engineering teams, most of the work is done by manually controlling the road marking machines, and the staff manually pushes the road marking machines to move. For road markings, since the road marking machines are equipped with movable rollers, skilled staff can control the road marking machines to move in a straight line and spray out straight marking lines based on their work experience. However, for less experienced staff, when pushing the road marking machines to move, it is easy to rotate the movable wheels, causing the road marking machines to deviate, and they cannot spray out a straight line effect, affecting the spraying effect of the road markings. Therefore, this device is designed to solve this problem.

[0032] When the device is used to mark the road, a battery is installed on the device for easy use. The battery is used to power the pump 8, the spray liquid is loaded into the liquid storage tank 7, and the device is pushed to the position where the marking line needs to be sprayed. When it is necessary to spray the straight line marking, the device is directly pushed to move, and the moving wheel 31 rolls on the ground, which will drive the first pulley 33 on the moving wheel 31 to rotate, thereby driving the first pulley 33 on the limiting plate 32 to rotate through the first belt 331. When the first pulley 33 on the limiting plate 32 rotates, it will drive the limiting plate 32 and the rotating shaft 321 to rotate at the same time. The limiting plates 32 are respectively installed at the front and rear sides of a moving wheel 31. By rotating the rotating shaft 321, the limiting plate 32 can be driven to slide continuously on the outer surface of the roller seat 311, so as to limit the roller seat 311 and prevent the roller seat 311 from deviating, so that the moving wheel 31 can move stably in a straight line and drive the driven wheel 2 to move.

[0033] At the same time, the pumping machine 8 is turned on, the spraying liquid in the liquid storage tank 7 is extracted by the pumping machine 8, and sprayed on the ground through the nozzle 9. As the device moves along a straight line, a straight line marking line can be sprayed to meet the use requirements.

[0034] After the spray liquid is sprayed out, a large amount of gas will be generated. In order to prevent a large amount of gas from being inhaled into the body of the staff, the device is provided with an exhaust fan 111 to absorb the gas. The specific operation is that when the rotating shaft 321 rotates, the first gear 12 will be driven to rotate, and the first gear 12 will drive the second gear 13 to rotate, so that the rotation of the rotating shaft 321 will drive the driving shaft 113 to rotate. At this time, the main driving wheel 14 installed on the driving shaft 113 will drive the auxiliary driving wheel 15 to rotate, and the arc plate 16 can be controlled to rotate, thereby driving the exhaust fan 111 to continuously circle around the nozzle 9, so as to facilitate the suction of the generated gas into the interior of the air inlet bin 112, and effectively prevent the spray liquid gas from being sucked into the body of the staff. In order to prevent the wires on the exhaust fan 111 from being entangled, a power supply can be installed on the arc plate 16 to provide power for the exhaust fan 111.

[0035] If arc marking is required, the first belt 331 is removed from the moving wheel 31. In order to ensure that a large amount of gas can still be absorbed when marking arc lines, a second pulley 19 is installed on the driven wheel 2, and a driving rod 18 is rotatably installed inside the base 1. Two third pulleys 17 are installed on the driving rod 18. The driven wheel 2 is connected to the driving rod 18 through the second belt 20. The first belt 331 removed from the moving wheel 31 is sleeved on the third pulley 17 on the outside of the driving rod 18. At this time, the moving wheel 31 has no limit.

[0036] By pushing the device forward, the roller seat 311 will move backward, so that the positions of the moving wheel 31 and the limiting plate 32 are offset, and then the roller seat 311 is positioned by the screw 6. At this time, pushing the device to move will drive the driven wheel 2 to roll, and the driven wheel 2 will control the driving rod 18 to rotate, thereby driving the third pulley 17 to rotate, and then the third pulley 17 drives the first pulley 33 on the limiting plate 32 to rotate, and continues to control the rotation of the arc plate 16, and continues to absorb the gas generated by the spraying liquid to avoid harm to the staff. By changing the moving angle of the moving wheel 31, the moving trajectory of the device can be changed, and an arc-shaped marking line can be sprayed.

[0037] When using the device, the screw 6 can pass through the interior of the limit plate 32 and be screwed into the interior of the base 1, so as to position the limit plate 32 so that it cannot shake at will. At the same time, the first belt 331 is also removed to reduce the wear of the first belt 331 and extend the use.

[0038] It should be noted that the liquid pump 8 and the air pump 111 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
