[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 5As shown, this utility model proposes a road marking robot marking device, including a moving mechanism 1, on which a marking mechanism 2 is mounted. The marking mechanism 2 includes a hot-melt mechanism 21 and a scraping mechanism 22. The hot-melt mechanism 21 includes a paint bucket 211 for storing paint. The paint bucket 211 has an electric heating element installed on its bottom and / or side wall. A paint outlet 217 is provided on one side of the paint bucket 211. The scraping mechanism 22 includes a first connecting frame 221, on which a second push-pull member 222 is mounted. A scraping bucket 223 is mounted on one end of the second push-pull member 222. A heating and heat preservation device 226 is installed on one side of the scraping bucket 223. The heating and heat preservation device 226 is used to heat the scraping bucket 223. A scraping bucket switch mechanism 224 is installed at the bottom of the scraping bucket 223. The moving mechanism 1 serves as the foundation of the entire device, supporting the marking mechanism. The marking mechanism 2 is divided into two main parts: a hot-melting mechanism 21 and a scraping mechanism 22, responsible for heating and melting the paint and applying it evenly, respectively. The paint bucket 211 stores the paint required for marking. Electric heating elements are installed at the bottom and / or side walls of the paint bucket to ensure the paint maintains a suitable temperature during use and prevents solidification. When the robot reaches the designated marking position, the paint flows into the scraping hopper 223 through the paint outlet 217. The position of the scraping hopper 223 can be adjusted by the second push-pull component 222 of the scraping mechanism 22 to ensure it is in contact with the ground. During operation, it is lowered to contact the ground; during non-operational transport, it is raised for easy transfer. The heating and insulation device 226 continuously heats the scraping hopper 223 to ensure good paint flowability. The scraping hopper switching mechanism 224 controls the paint flow rate to ensure the marking width and thickness meet standard requirements. The above design reduces the need for specialized personnel and lowers labor costs. Furthermore, both the electric heating element and the heating and insulation device 226 utilize electric heating, which, compared to other heating methods such as gas heating, offers higher energy conversion efficiency and reduces energy waste. The heating power can be adjusted according to actual needs, achieving precise energy supply and further improving energy efficiency. The electric heating element does not produce open flames, reducing fire and other safety hazards, making it particularly safer for use in flammable environments.
[0027] Optionally, in some embodiments, electric heating elements are installed on both the bottom and sidewalls of the paint bucket 211. When electric heating elements are installed on both the bottom and sidewalls of the paint bucket 211, it ensures that the paint is heated uniformly from all directions, avoiding problems such as localized overheating or insufficient heating. The electric heating elements on the bottom and sidewalls work together to rapidly increase the paint temperature in a short time, shortening the preheating time.
[0028] Optionally, in some embodiments, an electric heating element is installed at the bottom of the paint bucket 211. The bottom-mounted electric heating element can directly heat the paint inside the paint bucket 211, especially when the paint is thick or viscous. Bottom heating can quickly increase the paint temperature and shorten the preheating time.
[0029] Optionally, in some embodiments, electric heating elements are installed on the side walls of the paint bucket 211. These side-wall-mounted heating elements can heat the paint from multiple directions, ensuring a more uniform temperature distribution within the paint bucket 211 and avoiding localized overheating or underheating. Uniform heating of all parts of the paint bucket 211 reduces material aging or damage that may be caused by localized overheating, extending the service life of the paint bucket and its accessories.
[0030] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a temperature sensor and a liquid level sensor are provided inside the paint bucket 211. The temperature sensor detects the temperature of the paint bucket in real time, which facilitates the operator to control the opening or closing of the electric heating element. The liquid level sensor can detect the paint volume in real time, thereby avoiding overfilling during the paint filling process and avoiding insufficient material during the operation.
[0031] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the top of the paint bucket 211 is covered with a bucket lid 212, and the bucket lid 212 is equipped with a stirring device 213. The stirring device 213 is used to stir the paint in the paint bucket 211. The stirring device 213 includes a motor 2131 mounted on the bucket lid 212. The rotor of the motor 2131 is equipped with a connecting rod 2132. One end of the connecting rod 2132 passes through the bucket lid 212 and is disposed inside the paint bucket 211. At least one stirring blade 2133 is installed at one end of the connecting rod 2132. The stirring device 213 drives the connecting rod 2132 to rotate through the motor, thereby driving the stirring blade 2133 to continuously stir the paint, ensuring that the internal components of the paint are fully mixed, avoiding sedimentation or stratification. Uniform paint mixing helps to ensure the consistency of paint quality during the marking process, making each mark clear, uniform, and meeting the standard requirements. The stirring device 213 can prevent the coating from solidifying locally during the heating process, especially when the coating is thick or viscous. Continuous stirring helps maintain the good fluidity of the coating and avoids clogging the outlet. Stirring can also promote heat transfer inside the coating, making the coating temperature more uniform and further improving heating efficiency.
[0032] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the bucket lid 212 includes a horizontal plate 2121, and flaps 2122 are installed on both sides of the horizontal plate 2121, the flaps 2122 being hinged to the horizontal plate 2121. The design of the flaps 2122 allows workers to easily open and close the bucket lid 212 for adding paint or performing equipment maintenance. When no operation is required, the flaps 2122 can be completely closed to prevent dust, impurities, etc., from entering the paint bucket 211, ensuring the purity and quality of the paint. The hinged design of the flaps 2122 allows for quick opening and closing, improving operational efficiency.
[0033] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a filter screen 218 is installed on the top of the paint tank 211. The filter screen 218 can effectively prevent dust, particles, and other impurities from entering the paint tank 211, ensuring the purity and quality of the paint. Removing large particulate impurities through the filter screen 218 can reduce the wear of these impurities on the stirring device components. The filter screen 218 can also play a certain role in preventing splashing, reducing the risk of paint splashing during the filling process and improving operational safety.
[0034] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the paint outlet 217 is equipped with a guide hopper 216, and a sealing gate 215 is provided at one end of the guide hopper 216. The sealing gate 215 is slidably connected to the guide hopper 216, and a first push-pull member 214 is installed on one side of the sealing gate 215. The first push-pull member 214 is fixedly connected to the paint bucket 211. The sealing gate 215 is located at one end of the guide hopper 216 and can be flexibly opened and closed through the sliding connection, realizing precise control of paint flow. The automatic opening and closing of the sealing gate 215 can be realized by controlling the first push-pull member 214. According to actual needs, the position of the sealing gate 215 can be flexibly adjusted through the first push-pull member 214 to adapt to different marking speeds and paint flow requirements.
[0035] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the scraper switch mechanism 224 includes a support rod 22410, one end of which is hinged to a third push-pull member 2241, and one end of which is hinged to an L-shaped frame 2242. The L-shaped frame 2242 is hinged to the scraper hopper 223, and both ends of the L-shaped frame 2242 are provided with grooves 2243. A slider 2246 is disposed in the groove 2243. 46 is slidably connected to the groove 2243. A slide plate 2247 is fixedly connected to one side of the slider 2246. A concave part 2248 is provided on the top of the slide plate 2247. Guide rails 2245 are provided on both sides of the slide plate 2247. The slide plate 2247 is slidably connected to the guide rails 2245. A beveled section is provided on one side of the slide plate 2247. An L-shaped block 2249 is installed on one side of the concave part 2248. A scraper 2244 is installed on one side of the L-shaped block 2249. When the scraper switch mechanism 224 is in the closed state, the slide plate 2247 completely seals the outlet of the scraper hopper 223 to prevent paint from flowing out. When the coating hopper 223 needs to be opened to release paint, the third push-pull member 2241 pushes the L-shaped frame 2242, causing the L-shaped frame 2242 to swing accordingly. This causes the slider 2246 to slide along the groove 2243, and the slider 2246 drives the slide plate 2247 to slide on the guide rail 2245. The scraper 2244 moves to the open position, allowing paint to flow out of the coating hopper 223. When the coating hopper 223 is opened to release paint, the scraper 2244 smooths the paint. Conversely, when the coating hopper 223 needs to be closed, the fourth push-pull member 2241 retracts, applying a reverse force, which in turn causes the L-shaped frame 2242 to return to its original position. At this time, the slider 2246 and the slide plate 2247 also move until the scraper 2244 completely covers the opening of the coating hopper 223, preventing paint from flowing out.
[0036] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first push-pull member 214, the second push-pull member 222, and the third push-pull member 2241 are one or more combinations of a cylinder, a hydraulic cylinder, and an electric push rod.
[0037] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a second connecting frame 225 is installed on one side of the coating hopper 223, a first longitudinal rod 2251 is installed on one side of the second connecting frame 225, a sleeve 2252 is sleeved on the first longitudinal rod 2251, the sleeve 2252 is slidably connected to the first longitudinal rod 2251, the first longitudinal rod 2251 is fixedly connected to the coating hopper 223, and a positioning pin is sleeved inside one side of the sleeve 2252, the positioning pin is threadedly connected to the sleeve 2252. The second connecting bracket 225 supports the scraper hopper 223. The first longitudinal rod 2251 is fitted with a sleeve 2252, and the two are slidably connected. The sleeve 2252 can slide freely along the axial direction on the longitudinal rod 2251, thereby allowing the position of the scraper hopper 223 to be adjusted as needed. When it is necessary to fix the position of the scraper hopper 223, the positioning pin can be tightened to press it against the longitudinal rod 2251 and prevent the sleeve 2252 from continuing to slide. Conversely, the second positioning pin can be loosened to unlock it and allow the position to be adjusted again. Through this design, in conjunction with the second push-pull component 222, the height or angle of the scraper hopper 223 can be adjusted to adapt to different construction needs.
[0038] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the scraper hopper 223 is disposed below one end of the guide hopper 216, the bottom of the scraper hopper 223 is inclined to one side, and the bottom of the scraper hopper 223 is designed to be open. The open bottom and inclined to one side of the scraper hopper 423 help the paint to flow naturally to the opening under the action of gravity, ensuring that the paint can flow out smoothly and avoiding accumulation or blockage.
[0039] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a paint level detection device 227 is installed at one end of the first connecting frame 221. The paint level detection device 227 is one of an ultrasonic level gauge, a radar level gauge, or an optical level sensor.
[0040] Example 1:
[0041] This utility model proposes a road marking robot marking device, including a moving mechanism 1, on which a marking mechanism 2 is mounted. The marking mechanism 2 includes a hot-melt mechanism 21 and a scraping mechanism 22. The hot-melt mechanism 21 includes a paint bucket 211 for storing paint. An electric heating element is installed on the bottom and / or side wall of the paint bucket 211. A paint outlet 217 is opened on one side of the paint bucket 211. The scraping mechanism 22 includes a first connecting frame 221, on which a second push-pull member 222 is mounted. A scraping hopper 223 is mounted at one end of the second push-pull member 222. The scraping hopper 223 is located below one end of a guide bucket 216. The bottom of the scraping hopper 223 is tilted to one side and has an open design. The open design and tilted bottom of the scraping hopper 223 help the paint flow naturally to the opening under gravity, ensuring smooth flow and avoiding accumulation or blockage. A paint level detection device 227, which is an ultrasonic level gauge, is installed at one end of the first connecting frame 221. A heating and insulation device 226, which uses electric heating, is installed on one side of the scraper hopper 223. A scraper hopper switch mechanism 224 is installed at the bottom of the scraper hopper 223. The moving mechanism 1 serves as the foundation of the entire device, supporting the entire marking mechanism. The marking mechanism 2 is divided into two main parts: a hot-melting mechanism 21 and a scraping mechanism 22, responsible for heating and melting the paint and applying it evenly, respectively. The paint bucket 211 is used to store the paint required for marking. Electric heating elements are installed on the bottom and side walls of the paint bucket to ensure that the paint maintains a suitable temperature during use and prevents solidification. Electric heating elements are also installed on the bottom and side walls of the paint bucket 211. When electric heating elements are installed on both the bottom and side walls of the paint bucket 211, it ensures that the paint is heated evenly from all directions, avoiding localized overheating or underheating. The electric heating elements on the bottom and side walls work together to rapidly increase the paint temperature and shorten the preheating time. When the robot reaches the designated marking position, the paint flows into the scraper hopper 223 through the paint outlet 217. The position of the scraper hopper 223 can be adjusted by the second push-pull component 222 of the scraper mechanism 22 to ensure that it is in contact with the ground. It is lowered to contact the ground during operation and raised for easy transfer when not in operation. A second connecting frame 225 is installed on one side of the scraper hopper 223, and a first longitudinal rod 2251 is installed on one side of the second connecting frame 225. A sleeve 2252 is fitted over the first longitudinal rod 2251. The sleeve 2252 is slidably connected to the first longitudinal rod 2251, and the first longitudinal rod 2251 is fixedly connected to the scraper hopper 223. A positioning pin is fitted inside one side of the sleeve 2252 and is threadedly connected to the sleeve 2252.The second connecting bracket 225 supports the coating hopper 223. A sleeve 2252 is fitted over the first longitudinal rod 2251, and the two are slidably connected. The sleeve 2252 can slide freely axially on the longitudinal rod 2251, allowing the position of the coating hopper 223 to be adjusted as needed. When it is necessary to fix the position of the coating hopper 223, the positioning pin can be tightened to press against the longitudinal rod 2251, preventing the sleeve 2252 from sliding further. Conversely, loosening the second positioning pin unlocks the hopper and allows for readjustment. This design, used in conjunction with the second push-pull component 222, allows for adjustment of the height or angle of the coating hopper 223 to adapt to different construction needs. The heating and insulation device 226 continuously heats the coating hopper 223 to ensure good paint flowability. The coating hopper switching mechanism 224 controls the paint flow rate to ensure that the marking width and thickness meet standard requirements. The above design reduces the need for specialized personnel and lowers labor costs. Furthermore, both the electric heating element and the heating and insulation device 226 utilize electric heating, which, compared to other heating methods such as gas heating, offers higher energy conversion efficiency and reduces energy waste. The heating power can be adjusted according to actual needs, achieving precise energy supply and further improving energy efficiency. The electric heating element does not produce open flames, reducing fire and other safety hazards, making it particularly safer for use in flammable environments.
[0042] The paint bucket 211 is equipped with a temperature sensor and a liquid level sensor. The temperature sensor can detect the temperature of the paint bucket in real time, which makes it convenient for the staff to control the opening or closing of the electric heating element. The liquid level sensor can detect the paint volume in real time, thereby avoiding overfilling during the paint filling process and avoiding insufficient material during operation.
[0043] The top of the paint bucket 211 is covered by a lid 212, and a stirring device 213 is installed on the lid 212. The stirring device 213 is used to stir the paint inside the paint bucket 211. The stirring device 213 includes a motor 2131 mounted on the lid 212. The motor 2131 is a brushless geared motor. The rotor of the motor 2131 is equipped with a connecting rod 2132. One end of the connecting rod 2132 passes through the lid 212 and is located inside the paint bucket 211. At least one stirring blade 2133 is installed on one end of the connecting rod 2132. The stirring device 213 drives the connecting rod 2132 to rotate through the motor, which in turn drives the stirring blade 2133 to continuously stir the paint, ensuring that the internal components of the paint are fully mixed and avoiding sedimentation or stratification. Uniform paint mixing helps to ensure the consistency of paint quality during the marking process, making each mark clear, uniform, and in line with standard requirements. The stirring device 213 can prevent the coating from solidifying locally during the heating process, especially when the coating is thick or viscous. Continuous stirring helps maintain the good fluidity of the coating and avoids clogging the outlet. Stirring can also promote heat transfer inside the coating, making the coating temperature more uniform and further improving heating efficiency.
[0044] The lid 212 includes a horizontal plate 2121, with flaps 2122 mounted on both sides of the horizontal plate 2121, hinged to the horizontal plate 2121. The flaps 2122 are designed to allow operators to easily open and close the lid 212 for adding paint or performing equipment maintenance. When not in use, the flaps 2122 can be fully closed to prevent dust, impurities, etc., from entering the paint bucket 211, ensuring the purity and quality of the paint. The hinged design of the flaps 2122 allows for quick opening and closing, improving operational efficiency. A filter screen 218 is installed on the top of the paint bucket 211. The filter screen 218 effectively blocks dust, particles, and other impurities from entering the paint bucket 211, ensuring the purity and quality of the paint. Removing large particles through the filter screen 218 reduces wear on the mixing device components. The filter screen 218 also provides some splash protection, reducing the risk of paint splashing during filling and improving operational safety.
[0045] A guide hopper 216 is installed at the paint outlet 217. A sealing gate 215 is located at one end of the guide hopper 216, and the sealing gate 215 is slidably connected to the guide hopper 216. A first push-pull component 214 is installed on one side of the sealing gate 215, and the first push-pull component 214 is fixedly connected to the paint bucket 211. The sealing gate 215, located at one end of the guide hopper 216, can be flexibly opened and closed through the sliding connection, achieving precise control of paint flow. The automatic opening and closing of the sealing gate 215 can be achieved by controlling the first push-pull component 214. According to actual needs, the position of the sealing gate 215 can be flexibly adjusted via the first push-pull component 214 to adapt to different marking speeds and paint flow requirements.
[0046] The scraper switch mechanism 224 includes a support rod 22410, one end of which is hinged to a third push-pull member 2241, and the other end of which is hinged to an L-shaped frame 2242. The L-shaped frame 2242 is hinged to the scraper hopper 223. Both ends of the L-shaped frame 2242 are provided with grooves 2243. A slider 2246 is provided in the groove 2243 and is slidably connected to the groove 2243. A slide plate 2247 is fixedly connected to one side of the slider 2246. A concave member 2248 is provided on the top of the slide plate 2247. Guide rails 2245 are provided on both sides of the slide plate 2247 and are slidably connected to the slide plate 2247 and the guide rails 2245. A beveled section is provided on one side of the slide plate 2247. An L-shaped block 2249 is installed on one side of the concave member 2248 and a scraper 2244 is installed on one side of the L-shaped block 2249. When the scraper hopper switch mechanism 224 is in the closed state, the slide plate 2247 completely seals the outlet of the scraper hopper 223, preventing paint from flowing out. When it is necessary to open the scraper hopper 223 to release paint, the third push-pull member 2241 pushes the L-shaped frame 2242, causing the L-shaped frame 2242 to swing accordingly, causing the slider 2246 to slide along the groove 2243. The slider 2246 drives the slide plate 2247 to slide on the guide rail 2245, and the scraper 2244 moves to the open position, allowing paint to flow out of the scraper hopper 223. When the scraper hopper 223 is opened to release paint, the scraper 2244 smooths the paint. Conversely, when it is necessary to close the scraper hopper 223, the fourth push-pull member 2241 retracts to apply a reverse force, thereby causing the L-shaped frame 2242 to return to its original position. At this time, the slider 2246 and the slide plate 2247 also move until the scraper 2244 completely covers the opening of the scraper hopper 223, preventing paint from flowing out.
[0047] The first push-pull component 214, the second push-pull component 222, and the third push-pull component 2241 are cylinders.
[0048] Specifically, the working principle of this invention is as follows:
[0049] The road marking robot uses a marking device supported by a moving mechanism 1. The marking mechanism 2 is divided into a hot-melt mechanism 21 and a scraping mechanism 22. The paint tank 211 in the hot-melt mechanism 21 stores and heats the paint. Electric heating elements are installed on its bottom and side walls to ensure the paint maintains a suitable temperature during use and prevents solidification. The paint tank 211 also contains temperature and level sensors to monitor the paint temperature and volume in real time, ensuring operational safety and efficiency. When the robot reaches the designated position, the paint flows through the paint outlet 217 into the guide hopper 216 and finally into the scraping hopper 223.
[0050] The coating mechanism 22 includes a first connecting frame 221 and a second push-pull component 222. The second push-pull component 222 is equipped with a coating hopper 223, positioned below the guide hopper 216. The hopper's bottom is tilted to one side and has an open design, facilitating smooth paint flow. A heating and insulation device 226 is installed on one side of the coating hopper 223, using electric heating to maintain paint flowability. The coating hopper switching mechanism 224 controls the opening and closing of the slide plate 2247 via a third push-pull component 2241, precisely adjusting the paint flow rate to ensure the marking width and thickness meet standard requirements. The sealing door 215 controls the opening and closing of the guide hopper 216 via the first push-pull component 214, further optimizing paint flow management.
[0051] Both the second push-pull component 222 and the third push-pull component 2241 of the scraper switch mechanism 224 are cylinder-driven, enabling automated operation, reducing the need for manual intervention, and improving work efficiency and safety. Furthermore, the scraper hopper 223, through a sliding connection design of the second connecting frame 225, the first longitudinal rod 2251, and the sleeve 2252, allows for flexible height adjustment as needed. This significantly reduces labor costs and energy consumption.
[0052] In summary, this utility model solves the problems of high labor costs, inefficient and unstable work quality, and safety hazards caused by the current road marking operation's heavy reliance on manual labor.
[0053] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0054] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
