Description

Technical Field

[0001] This invention relates to the field of line marking machines, and more particularly to a road line marking machine. Background Technology

[0002] When drawing various solid and dashed lines on highways, a road marking machine is needed. For example, patent application number 201921234899.8 discloses a road marking machine, including a base plate. Supports are fixedly connected to the four corners of the bottom of the base plate. Pullers are movably connected to the bottom of the supports. A positioning frame is fixedly connected to the top of the base plate. A compression pump is fixedly connected to the top of the base plate. A first pipe is connected to the left side of the compression pump. The side of the first pipe away from the compression pump extends to the bottom of the base plate and connects to a nozzle. A second connecting pipe is connected to the right side of the compression pump. A discharge pipe is connected to the top of the second connecting pipe. This utility model solves the problem that existing road marking machines lack the ability to mix marking materials by using a base plate, supports, pulleys, positioning frame, compression pump, first pipe, nozzle, second connecting pipe, discharge pipe, housing, motor, first stirring paddle, first gear, second gear, second stirring paddle, feed pipe, heating device, solenoid valve, and push handle in a coordinated manner.

[0003] However, the aforementioned line marking machines and similar line marking machines require pre-marking lines on the road to indicate the direction of the lines before use. Then, the line marking machine is used to draw various solid and dashed lines along the pre-marked lines. Taking the pre-marking of lines in the center of the road as an example, in order to keep the line in the center of the road and prevent the solid or dashed lines drawn by the line marking machine from being skewed, it is necessary to measure constantly during the line marking process, which increases the workload of line marking and requires improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a road marking machine to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0022] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0023] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1-4 As shown, a road marking machine includes multiple measuring rods 3 and multiple measuring cylinders 4 arranged side by side. The measuring rods 3 are slidably inserted into the measuring cylinders 4. Both the measuring rods 3 and the measuring cylinders 4 are provided with scales 5. An alignment mechanism is installed at the left end of the measuring rods 3 and a marking mechanism is installed at the right end of the measuring cylinders 4.

[0026] The alignment mechanism includes a support base 6, with a counterweight 13 fixedly mounted on the left side. A cavity 12 is provided at the bottom of the support base 6, within which a left wheel 10 and a right wheel 37 are mounted. Both the left wheel 10 and the right wheel 37 are fixedly mounted on a rotating shaft 9, with both ends of the shaft 9 rotatably connected to the support base 6. A slide rail 19 is provided at the bottom of both the left wheel 10 and the right wheel 37, with a guide rod 17 slidably inserted within the slide rail 19. The bottom of the guide rod 17 is spiked, and its upper end is fixedly connected to the lower end of a first spring 20. Fixed to the rotating shaft 9, the left wheel 10 and the right wheel 37 are both provided with a sliding groove 16 on the side that is close to each other. The sliding groove 16 is connected to the slide rail 19. A drive plate 15 is provided in the sliding groove 16. The drive plate 15 is fixed to the guide rod 17. A controller 14 is fixed on the drive plate 15 located on the left wheel 10. A self-reset control button 18 is provided on the top of the controller 14. A stop block 11 is fixed on the top of the rotating shaft 9. An electric telescopic rod 7 is provided above the stop block 11. The electric telescopic rod 7 is fixed to the support base 6. The controller 14 is wirelessly connected to the electric telescopic rod 7.

[0027] Working principle: When in use, place this device on road 2, with the left wheel 10 and the right wheel 37 positioned on the left and right sides of one edge of road 2, respectively. The right wheel 37 should be pressed on road 2, and the left wheel 10 should be pressed on the soil 1 beside road 2. Then move the measuring cylinder 4 and adjust the position of the marking mechanism according to the scale 5. Taking marking a line in the center of road 2 as an example, adjust the position of the marking mechanism to the center of road 2, and then push the device. When moving the device, ensure that one edge of road 2 is always between the left wheel 10 and the right wheel 37 to mark a line in the center of road 2.

[0028] When one edge of the road 2 is always between the left wheel 10 and the right wheel 37, the right wheel 37 is pressed on the road 2, and the left wheel 10 is pressed on the ground 1 next to the road 2. When the guide rod 17 on the left wheel 10 contacts the ground 1, it is inserted into the ground 1. When the guide rod 17 on the right wheel 37 contacts the road 2, it is pressed into the right wheel 37. At this time, the two drive plates 15 are misaligned, the self-reset control button 18 is no longer pressed, and the controller 14 controls the electric telescopic end 9 of the electric telescopic rod 7 to retract. At this time, the electric telescopic end 8 does not contact the stop block 11, and the shaft 9, the left wheel 10, and the right wheel 37 can rotate smoothly.

[0029] When the movement of the left wheel 10 and the right wheel 37 deviates (both the left wheel 10 and the right wheel 37 move onto the ground 1, or both the left wheel 10 and the right wheel 37 move onto the road 2), when the guide rod 17 contacts the ground 1 or the road 2, both guide rods 17 simultaneously penetrate into the ground 1, or retract into the left wheel 10 and the right wheel 37. At this time, the two drive plates 15 contact, causing the self-reset control button 18 to be pressed. The controller 14 controls the electric telescopic end 9 of the electric telescopic rod 7 to extend. At this time, the electric telescopic end 8 contacts the stop block 11, and the rotation of the shaft 9, the left wheel 10 and the right wheel 37 is blocked by the electric telescopic end 8, preventing the left wheel 10 and the right wheel 37 from rotating. The device stops moving, which can remind the operator that the movement of the device has deviated, and can also automatically stop the marking to prevent the marking from deviating.

[0030] Example 2

[0031] like Figure 1-4 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the scribing mechanism includes a scribing box 36, the top of which is connected to the cover plate 24 via a hinge 21, the scribing box 36 is fixed to the right end of the measuring cylinder 4, a roller 23 is provided inside the scribing box 36, an opening 38 is provided at the bottom of the scribing box 36, the bottom of the roller 23 is located inside the opening 38, multiple sponges 22 are fixedly fixed at equal intervals along the circumference of the roller 23, the roller 23 is fixedly sleeved on the second rotating shaft 32, and bearings 29 are sleeved on both the left and right ends of the second rotating shaft 32. The outer ring is fixedly connected to the slider 30, the slider 30 is slidably connected to the slide rail 27, the slide rail 27 is fixedly connected to the inner wall of the scribing box 36, the bearing 29 is fixedly connected to the upper end of the second spring 31, the lower end of the second spring 31 is fixedly connected to the scribing box 36, the upper end of the slide rail 27 is fixedly provided with a support block 25, the support block 25 is threadedly connected with a drive screw 28, the lower end of the drive screw 28 abuts against the bearing 29, the upper end of the drive screw 28 is fixedly provided with a knob 26, the bottom of the scribing box 36 is fixedly provided with multiple U-shaped brackets 35, the support shaft 34 is rotatably connected inside the U-shaped brackets 35, and the driven wheel 33 is fixedly sleeved on the support shaft 34.

[0032] Working principle: Open the cover plate 24, let the sponge 22 absorb the pigment, and then rotate the drive screw 28 to move the drive screw 28 down and drive the bearing 29 down along the slide rail 27. The bearing 29 drives the roller 23 to move down synchronously through the second rotating shaft 32, so that the roller 23 contacts the road 2. During the movement of this device, the roller 23 rolls along the road 2, so that the sponge 22 prints a dotted line on the road surface of the road 2.
