[0008] By adopting the above scheme, after the generator generates electricity, the electricity is respectively input into the chassis and the shooting mechanism through the conductive harness, so that the chassis and the shooting mechanism can be used with electricity as the driving source, and the processor inside the chassis can be controlled by the remote controller after power is turned on. After the staff controls the processor through the remote controller, the control signal sent by the processor can be input into the smart module through the optical fiber, and the device completes the specific operation process through the smart module, and the chassis can be cooled through the heat dissipation slots on the left and right sides to avoid overheating of the chassis.

[0009] As a preferred embodiment, the shooting mechanism is arranged on the top of the bracket, and the interior of the bracket is provided with an extension rod that can be retracted in an embedded shape.

The top of the camera is provided with a sun visor covering the front edge of the camera.

[0010] By adopting the above scheme, when the staff remotely operates the vehicle to move, the actual road conditions are filmed through the cameras at the four corners of the shooting mechanism, so that the staff can accurately control the movement trajectory of the vehicle according to the on-site images transmitted by the camera, and the camera can rotate under the drive of the rotating support rod, so that the camera's shooting range is wider, effectively reducing the camera blind spot, and when the device is shooting road conditions in a strong light environment, the sun visor on the top of the camera can block the sunlight to avoid exposure when the camera is shooting, thereby improving the clarity of the road condition picture.

The paint injection port is funnel-shaped as a whole, and the stirring rod is located in the middle of the paint bucket. The stirring blades are distributed in a longitudinally equidistant arrangement, and the stirring blades rotate in a staggered manner.

[0012] By adopting the above scheme, the paint required for dot marking can be stirred by rotating the stirring blades driven by the stirring rod when it is injected into the paint bucket through the paint injection port, so as to avoid the paint from settling and agglomerating, thereby ensuring that the marking can be clear during the dot marking process and the paint flows out through the drip hole.

[0013] As a preferred embodiment, the first rolling track includes a first driving wheel, a first auxiliary wheel and track teeth, the first driving wheels are respectively located on the first rolling track, and the track teeth are arranged at equal intervals laterally on the front and back sides of the first rolling track, the tooth marks on the surface of the first driving wheel are in a bite-like shape with the track teeth on the inner circle of the first rolling track, the first auxiliary wheel presses against and arches the top middle of the first rolling track, and one end of the first auxiliary wheel is connected to the side of the vehicle body.

[0014] By adopting the above scheme, the first rolling track is driven by the first driving wheels on the left and right sides of the inner circle when rolling, in a manner that the surface tooth marks bite the track teeth of the inner circle of the first rolling track, so that the first rolling track can roll in a cycle, and the friction of the first rolling track is increased by the contact between the track teeth on the outer circle surface of the first rolling track and the ground, which can prevent the vehicle body from slipping and improve the grip. While the first rolling track improves the rolling smoothness of the first rolling track by rolling the first auxiliary wheel, it can also strengthen the tension of the first rolling track to prevent the first rolling track from falling off due to being too loose or breaking due to being too tight.

[0015] As a preferred embodiment, auxiliary devices are installed on both sides of the left and right sides of the vehicle body, and second rotatable auxiliary wheels are installed on both ends of the bottom of the auxiliary devices, the surface of the second auxiliary wheel is toothed, and the tooth marks on the surface of the second auxiliary wheel are engaged with the track teeth at the lower end of the inner ring of the first rolling track, and the second auxiliary wheel is flat and pressed against the first rolling track.

[0016] By adopting the above scheme, when the bottom of the first rolling track touches the ground, the driving performance of the first rolling track can be enhanced by the second auxiliary wheel at the bottom of the auxiliary device biting the inner ring track teeth of the first rolling track, and the flatness of the first rolling track where it touches the ground can be ensured, thereby avoiding bumps in the vehicle body during movement.

The second driving wheel and the first driving wheel can perform fixed-point circular rotation movement, and the connecting arm is located on the left and right sides of the second driving wheel, and one end of the connecting arm is connected to the third auxiliary wheel.

[0018] By adopting the above scheme, if the vehicle body encounters a steep slope or an obstacle while maintaining a straight line to mark dots, a force point is formed by adjusting the second rolling track forward, so that the vehicle body can be lifted into the air by the second rolling track, and the second rolling track rolls in a circle with the second driving wheel taking the first driving wheel as the axis of action, driving the internal connecting arm of the second rolling track to unfold forward, and the unfolding angle of the second rolling track can be adjusted by different rotation angles, thereby improving the obstacle avoidance performance of the device during the marking process.

The fixed mounting frame is a double-layer design, and the telescopic rods are located at the four corners between the two fixed mounting frames.

[0020] By adopting the above scheme, the stirred paint is discharged from the drip hole and then received through the material receiving funnel, and is input into the interior of the dot spray gun through the hollow hose on one side of the material receiving funnel. The paint is then compressed by the dot spray gun and sprayed onto the ground through the nozzle to complete the dot marking work. When the vehicle body is avoiding or crossing an obstacle, the distance between the dot spray gun and the ground can be adjusted by telescopic rod extension and retraction to prevent the dot spray gun from colliding with the obstacle during the obstacle avoidance process.

[0021] As a preferred embodiment, a method for adjusting the distance marking device for road and bridge construction comprises the following steps:

[0022] S1: The generator introduces electricity into the chassis through the conductive harness, so that the processor inside the chassis starts to work. The staff can manually control the processor through the remote controller, and the control signal is input into the intelligent module through the optical fiber, thereby completing the control steps of the device;

[0023] S2: The first rolling crawler is driven by the first driving wheels on the left and right sides of the inner circle in a manner that the surface tooth marks bite the track teeth of the inner circle of the first rolling crawler, so that the first rolling crawler can be cyclically rolled, and the friction of the first rolling crawler is improved by the contact between the track teeth on the outer circle surface of the first rolling crawler and the ground, which can prevent the vehicle body from slipping and improve the grip. While the first rolling crawler improves the rolling smoothness of the first rolling crawler through the rolling of the first auxiliary wheel, it can also strengthen the tension of the first rolling crawler to avoid the first rolling crawler from falling off due to being too loose or breaking due to being too tight. When the vehicle body encounters a steep slope or obstacle while maintaining a straight line to mark dots, a force point is formed by adjusting the second rolling crawler forward, so that the vehicle body can be lifted up by the second rolling crawler, and the second rolling crawler rolls in a circle in a manner that the second driving wheel takes the first driving wheel as the axis of action, driving the internal connecting arm of the second rolling crawler to unfold forward, and the unfolding angle of the second rolling crawler can be adjusted by different rotation angles, thereby improving the obstacle avoidance performance of the device during the marking process.

[0024] S3: The staff injects the paint for dot marking into the paint bucket from the paint injection port, and the paint injected into the paint bucket can be stirred by the stirring blades driven by the stirring rod inside the paint bucket. Since the stirring blades stir in a staggered manner, the paint inside the paint bucket can be stirred multiple times in a short period of time, avoiding the occurrence of lumps inside the paint bucket and ensuring the clarity of the marking when the device is marking dots. The stirred paint is discharged through the drip hole;

[0025] S4: The stirred paint is discharged from the drip hole and then received through the receiving funnel, and is input into the dot spray gun through the hollow hose on one side of the receiving funnel. The paint is then compressed by the dot spray gun and sprayed onto the ground through the nozzle to complete the dot marking work. When the vehicle body is avoiding or crossing an obstacle, the distance between the dot spray gun and the ground can be adjusted by telescopic rod to avoid collision between the dot spray gun and the obstacle during obstacle avoidance.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The road bridge construction distance marking device and method thereof are provided with a first rolling crawler that rolls in a circular manner on a first driving wheel and a first auxiliary wheel, so that the vehicle body can move under the drive of the first rolling crawler, and the angle of the second rolling crawler is adjusted in a circular manner in cooperation with the second driving wheel, so that the vehicle body can be tilted with the second rolling crawler as a fulcrum to avoid obstacles, thereby resulting in accurate marking positions of subsequent devices, and workers do not need to repeatedly calculate when performing measurement and calculation, thereby improving the accuracy of the device's marking.

[0028] The road bridge construction distance marking device and method thereof are provided with a shooting mechanism, a shooting device, a sun visor and a rotating support rod. When a staff member remotely operates the vehicle body 1 to move, the camera at the four corners of the shooting mechanism shoots the actual road conditions, so that the staff member can accurately control the moving trajectory of the vehicle body 1 according to the on-site images transmitted by the camera. The camera can rotate under the drive of the rotating support rod, so that the camera can shoot a wider range of images, effectively reducing the blind spots of the camera. Moreover, when the device shoots road conditions in a strong light environment, the sun visor on the top of the camera can block the sunlight, avoiding the exposure of the camera when shooting, thereby improving the clarity of the road condition images.

[0029] The road bridge construction distance marking device and method thereof are provided with a paint bucket, a paint injection port, a stirring rod, a stirring blade and a drip hole. A worker injects the paint for marking into the paint bucket from the paint injection port, and the paint injected into the paint bucket can be stirred by the stirring blade driven by the stirring rod inside the paint bucket. Since the stirring blade stirs in an interlaced manner, the paint inside the paint bucket can be stirred multiple times in a short time, thereby avoiding the occurrence of agglomeration inside the paint bucket and ensuring the clarity of the marking position when the device is marking. The stirred paint is discharged through the drip hole.

[0030] The road and bridge construction distance marking dotting equipment and method thereof are provided with a dotting spray gun, a nozzle, a hollow hose, a fixed mounting frame, a material receiving funnel and a telescopic rod. The stirred paint is discharged from the drip hole and then received through the material receiving funnel, and is input into the interior of the dotting spray gun through the hollow hose on one side of the material receiving funnel. Subsequently, the paint is compressed by the dotting spray gun and sprayed onto the ground through the nozzle to complete the dotting marking work. When the vehicle body is avoiding or crossing an obstacle, the distance between the dotting spray gun and the ground can be adjusted by telescoping the telescopic rod to avoid the dotting spray gun and the obstacle from colliding during the obstacle avoidance process.

[0049] This embodiment also provides a method for using a road and bridge construction distance marking device, comprising the following steps:

[0050] S1: The generator 5 introduces electricity into the chassis 2 through the conductive harness 501, so that the processor 202 inside the chassis 2 starts to work.

While the first rolling crawler 4 is rolled by the first auxiliary wheel 402 to improve the rolling smoothness of the first rolling crawler 4, the tension of the first rolling crawler 4 can also be strengthened to prevent the first rolling crawler 4 from being too loose. In the event of falling off or breaking due to over-tightening, if the vehicle body 1 encounters a steep slope or obstacle while maintaining a straight line to mark dots, a force point is formed by adjusting the second rolling track 12 forward, so that the vehicle body 1 can be lifted up by the second rolling track 12, and the second rolling track 12 rolls in a circle with the second driving wheel 1201 and the first driving wheel 401 as the axis of action, driving the internal connecting arm 1202 of the second rolling track 12 to unfold forward, and the unfolding angle of the second rolling track 12 can be adjusted by different rotation angles, thereby improving the obstacle avoidance performance of the device during the marking process.

The stirred paint is discharged through the drip hole 605;

[0053] S4: The stirred paint is discharged from the drip hole 605 and then received by the material receiving funnel 1305, and is input into the interior of the dot spray gun 13 through the hollow hose 1302 on one side of the material receiving funnel 1305.

9. A marking method for a distance marking device for road and bridge construction, according to the distance marking device for road and bridge construction according to any one of claims 1 to 8, Features , including the following steps: S1: The generator (5) introduces electric power into the interior of the chassis (2) through the conductive wire harness (501), so that the processor (202) inside the chassis (2) starts to work. The staff can manually control the processor (202) through the remote controller, and the control signal is input into the interior of the intelligent module (203) through the optical fiber (204), thereby completing the control steps of the device; S2: The first rolling crawler (4) is driven by the first driving wheels (401) on the left and right sides of the inner ring when rolling, in a manner that the surface tooth marks bite the crawler teeth (403) of the inner ring of the first rolling crawler (4), so that the first rolling crawler (4) can be cyclically rolled, and the crawler teeth (403) on the outer ring surface of the first rolling crawler (4) contact the ground to increase the friction of the first rolling crawler (4), thereby preventing the vehicle body (1) from slipping and improving the grip. The first rolling crawler (4) can also increase the tension of the first rolling crawler (4) while improving the rolling smoothness of the first rolling crawler (4) through the rolling of the first auxiliary wheel (402), thereby preventing the first rolling crawler (4) from slipping due to the first rolling crawler (4). If the vehicle body (1) is too loose and falls off, or is too tight and breaks, when it encounters a steep slope or an obstacle while maintaining a straight line to mark dots, the second rolling crawler (12) is adjusted forward to form a force point, so that the vehicle body (1) can be lifted up by the second rolling crawler (12), and the second rolling crawler (12) rolls in a circle with the second driving wheel (1201) and the first driving wheel (1201) as the axis of action, driving the internal connecting arm (1202) of the second rolling crawler (12) to unfold forward, and the unfolding angle of the second rolling crawler (12) can be adjusted by different rotation angles, thereby improving the obstacle avoidance performance of the device during the marking process. S3: The staff injects the paint for dot marking into the paint bucket (601) from the paint injection port (602), and the paint injected into the paint bucket (601) can be stirred by the stirring rod (603) inside the paint bucket (601) rotating to drive the stirring blade (604). Since the stirring blade (604) stirs in an interlaced manner, the paint inside the paint bucket (601) can be stirred multiple times in a short period of time, thereby avoiding the occurrence of lumps inside the paint bucket (601) and ensuring the clarity of the marking location when the device is marking dots. The stirred paint is discharged through the drip hole (605); S4: The stirred paint is discharged from the drip hole (605) and then received by the material receiving funnel (1305), and then input into the interior of the dot spray gun (13) through the hollow hose (1302) on one side of the material receiving funnel (1305). The paint is then compressed by the dot spray gun (13) and sprayed onto the ground through the nozzle (1301) to complete the dot marking work. When the vehicle body (1) is avoiding or crossing an obstacle, the distance between the dot spray gun (13) and the ground can be adjusted by telescopic rod (1304) to avoid collision between the dot spray gun (13) and the obstacle during the obstacle avoidance process.
