It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0027] like Figure 1-5 As shown, a road bridge dotting device includes a laser level 1 and a dotting robot body 2 arranged at the two ends of the dotting section, one end of the dotting robot body 2 is fixedly installed with a laser sensor 3 for guiding the movement of the dotting robot body 2 according to the laser, the internal lifting movable assembly of the dotting robot body 2 is equipped with a dotting pen assembly 4 for completing the dotting work, one end of the inside of the dotting robot body 2 is fixedly installed with a liquid pushing tube 8 and an air pushing tube 9 for injecting ink inside the liquid pushing tube 8 into the dotting pen assembly 4, and an air pump body 12 for replenishing the air pressure inside the air pushing tube 9 is installed inside the dotting robot body 2 and below the air pushing tube 9.

[0028] Refer to the attached Figure 3 and Figure 4A fixed tube 7 is fixedly installed inside the body 2 of the dotting robot, and the dotting pen assembly 4 is composed of an outer pen tube 401 and an inner pen core 403 in a telescopic manner. The inner pen core 403 is telescopically assembled into the inner part of the outer pen tube 401, and the outer pen tube 401 and the fixed tube 7 form a telescopic assembly. A stopper 405 is integrally arranged in the middle part of the inner pen core 403, a plug rod 406 is fixedly connected to the center axis of the circle inside the outer pen tube 401, and a stopper 407 for blocking the stopper 405 is fixedly arranged at the end of the plug rod 406 extending to the inner part of the inner pen core 403; a spring 408 is fixedly installed inside the outer pen tube 401 and at the top of the inner pen core 403, a straight through groove 402 for a liquid injection tube 409 to pass through is opened on the side wall of the outer pen tube 401, and a soft pad 404 is fixedly sleeved on the bottom outer wall of the inner pen core 403.

[0029] Refer to the attached Figure 3 and Figure 4 A cylinder 5 is fixedly installed inside the body 2 of the dotting robot, and a rotating arm 6 is rotatably installed inside the body 2 of the dotting robot. The telescopic output end of the cylinder 5 is connected to the rotating arm 6, and the end of the rotating arm 6 is connected to the outer wall of the outer pen tube 401.

[0030] According to the above structure, two laser level meters 1 are arranged at the two ends of the marking section, and the laser sensor 3 is used to sense the straight laser emitted by the laser level meter 1. Then the robot body 2 can move forward along the laser. During the robot's forward movement, the cylinder 1 5 is started at a fixed frequency and controls the reciprocating deflection of the rotating arm 6. At this time, the outer pen tube 401 moves back and forth up and down together with the inner pen core 403. Before the outer pen tube 401 moves downward to the extreme position, the inner pen core 403 will first contact the ground. The soft pad 404 is used to protect the pen tip of the inner pen core 403. Then the inner pen core 403 will retract into the outer pen tube 401 and squeeze the spring 1 408. The stopper 407 will leave the stopper 405, and the interior of the inner refill 403 will be unblocked, and the inner refill 403 can spray a certain amount of ink onto the ground, thereby completing the work of fixed-distance punctuation. In the above process, this dotting pen assembly 4 cooperates with the cylinder 5 to spray a certain amount of ink onto the ground at equal intervals, and the point spacing can be achieved by adjusting the frequency of the cylinder 5, and the dotting robot body 2 cooperates with the laser level 1 to automatically complete the dotting and marking work of one end of the bridge, which has the advantage of fully automatic intelligent dotting. In addition, the pen tip of the inner refill 403 can complete the marking at a certain distance from the ground, and it also has a soft pad 404 to protect the pen tip.

[0031] Refer to Appendix 3. Figure 4 and Figure 5The inner pen core 403 is connected to the liquid pushing tube 8 through the injection tube 409, and a liquid plug 801 is movably assembled at one end of the liquid pushing tube 8. The liquid pushing tube 8 is connected to the air pushing tube 9 through a pipeline equipped with a valve 11, and a valve plug rod 1101 for controlling the internal circulation is movably inserted at the bottom of the valve 11. One end of the air pushing tube 9 is connected and assembled with an air plug 901 through a spring 902, and the other end of the air pushing tube 9 is connected to the air outlet of the air pump body 12 through an air supply tube 903. A one-way valve is installed at one end of the air supply tube 903 close to the air pushing tube 9, and a transmission housing 1202 is integrally provided at one end of the air pump body 12, and the internal rotation assembly of the transmission housing 1202 is equipped with a working shaft tube 1203 used as a power shaft, and the inner wall of the end of the working shaft tube 1203 is fixedly provided with inner sharp cone teeth.

[0032] Refer to the attached Figure 3 , Figure 4 and Figure 5 A rectangular tube 15 is rotatably installed inside the body 2 of the dotting robot, and a rectangular rod 16 is telescopically assembled on the top of the rectangular tube 15, a bevel gear 17 is fixedly installed on the bottom of the rectangular tube 15, and a bevel gear 1601 for detachably meshing with the inner bevel gear is fixedly installed on the top of the rectangular rod 16; a driving wheel shaft 201 for installing a moving wheel is rotatably assembled at the bottom of both ends of the body 2 of the dotting robot, a gear 1 202 is fixedly sleeved in the middle of the driving wheel shaft 201, a bevel gear 18 meshing with the bevel gear 17 is rotatably installed inside the body 2 of the dotting robot, and a gear 2 19 meshing with the gear 202 is fixedly assembled on one side of the bevel gear 18.

[0033] Refer to the attached Figure 4 and Figure 5 A cylinder 2 13 is fixedly installed inside the body 2 of the dot-marking robot, and the telescopic output end of the cylinder 2 13 is fixedly connected to a connecting plate 14, the end of the valve plug rod 1101 is fixedly connected to one end of the connecting plate 14, and the rectangular rod 16 is rotatably assembled on the other end of the connecting plate 14.

[0034] According to the above structure, since the second spring 902 is in a compressed state, when the inner core 403 is in a clear state, the gas plug 901 will push a part of the gas into the liquid pushing tube 8, causing the liquid plug 801 in the liquid pushing tube 8 to start moving, and the liquid plug 801 will then inject the ink in the liquid pushing tube 8 into the inner core 403 through the liquid injection tube 409, and the inner core 403 can spray a certain amount of ink onto the ground, thereby completing the work of fixed-distance punctuation;

[0035] Furthermore, when the gas plug 901 cannot be reset to the origin due to leakage of the gas inside the air push pipe 9, the air cylinder 2 13 is started at this time, and its operation drives the connecting plate 14 to move upward, the valve plug rod 1101 will be inserted into the valve 11 to close it, and the rectangular rod 16 will extend from the top of the rectangular tube 15, and the pointed bevel gear 1601 will mesh with the inner pointed bevel teeth in the working shaft tube 1203, and then the moving wheel will roll, and the meshing of the gear 1 202 and the gear 2 19 will drive the bevel gear 2 18 to rotate, and then the meshing of the bevel gear 17 and the bevel gear 2 18 will drive the working shaft tube 1203 to rotate, and the air pump body 12 will operate and replenish gas into the air push pipe 9. After the replenishment is completed, the air cylinder 2 13 is controlled to separate the pointed bevel gear 1601 from the working shaft tube 1203;

[0036] In the above process, the energy storage type liquid push tube 8 and air push tube 9 can cooperate with the dotting pen assembly 4 to complete the punctuation work at one end distance, so that the ink export work does not require the frequent and fixed-frequency start-up of the power equipment, thereby optimizing the power consumption capacity of the robot and extending the duration of the robot's single work as much as possible; in addition, the work of replenishing the air pressure inside the air push tube 9 is completed by utilizing the kinetic energy of the robot when moving, which further reduces the power consumption capacity of the equipment.

[0037] Refer to the attached Figure 4 A liquid storage tank 10 is fixedly installed inside the dotting robot body 2 and above the liquid pushing tube 8, and an oil pump for pumping ink into the liquid pushing tube 8 is installed inside the liquid storage tank 10. An oil pipe equipped with a solenoid valve 1001 is connected between the liquid pushing tube 8 and the liquid storage tank 10.

[0038] According to the above structure, when the ink in the liquid pushing tube 8 is exhausted, the solenoid valve 1001 opens, the oil pump in the liquid storage tank 10 starts and pumps the ink into the liquid pushing tube 8, at which time the liquid plug 801 and the air plug 901 will reset and move.

[0039] The working principle of the utility model is as follows: two laser level meters 1 are arranged at the ends of the dot-marking section, and the laser sensor 3 is used to sense the straight laser emitted by the laser level meter 1, and then the robot body 2 can move forward along the laser. During the robot's forward movement, the cylinder 1 5 is started at a fixed frequency and controls the reciprocating deflection of the rotating arm 6. At this time, the outer pen tube 401 moves back and forth up and down together with the inner pen core 403. Before the outer pen tube 401 moves downward to the extreme position, the inner pen core 403 will first contact the ground, and the soft pad 404 is used to protect the pen tip of the inner pen core 403. Then the inner pen core 403 will retract into the outer pen tube 401 and squeeze the spring 1 408, and the stopper 407 will leave the stopper 405, and the inside of the inner pen core 403 will be unblocked.

[0040] Since the spring 2 902 is in a compressed state, when the inner core 403 is unblocked, the gas plug 901 will push a portion of gas into the liquid pushing tube 8, causing the liquid plug 801 in the liquid pushing tube 8 to start moving, and the liquid plug 801 will then inject the ink in the liquid pushing tube 8 into the inner core 403 through the liquid injection tube 409, and the inner core 403 can spray a certain amount of ink onto the ground, thereby completing the work of fixed-distance punctuation;

[0041] When the ink in the liquid pushing tube 8 is exhausted, the solenoid valve 1001 is opened, the oil pump in the liquid storage tank 10 is started and the ink is pumped into the liquid pushing tube 8, at which time the liquid plug 801 and the air plug 901 will be reset and moved;

[0042] When the gas inside the air push pipe 9 leaks and the air plug 901 cannot be reset to the origin, the cylinder 2 13 is started at this time, and its operation drives the connecting plate 14 to move upward, the valve plug rod 1101 will be inserted into the valve 11 to close it, and the rectangular rod 16 will extend from the top of the rectangular tube 15, and the pointed bevel gear 1601 will mesh with the inner pointed bevel teeth in the working shaft tube 1203, and then the moving wheel rolls, and the meshing of gear 1 202 and gear 2 19 drives the bevel gear 2 18 to rotate, and then the meshing of bevel gear 17 and bevel gear 2 18 drives the working shaft tube 1203 to rotate. At this time, the air pump body 12 will operate and replenish gas into the air push pipe 9. After the replenishment is completed, the cylinder 2 13 is controlled to separate the pointed bevel gear 1601 from the working shaft tube 1203.

[0043] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
