Since road markings need to strictly follow specifications, and manual control is considered to be more accurate to a certain extent, most of the current line marking devices are still mainly manual. However, due to the fact that the storage area usually has a certain weight, and with continuous pushing for a long time, even experienced construction workers are difficult to completely avoid displacement problems. As a result, the straightness of the markings may be affected, leading to uneven markings, which affects the aesthetics and standardization of the road. Secondly, displacement may cause the width and thickness of the markings to be uneven, affecting the reflective effect and durability of the markings; 2. And for many line marking devices, the way to drive the spraying structure is still manual operation, which means that it is necessary to move the frame while operating the spraying position. Manual operation is prone to incoherence and unevenness, and there is also a phenomenon of excessive paint dripping during this process. This not only causes waste of paint, but also pollutes the road surface, increasing the cleaning cost, and the dripping paint may affect the appearance quality and reflective effect of the markings.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a marking device with a positioning function, including a frame 1. The top of the frame 1 is bolted with a material barrel 2. A stirring member 3 is provided inside the material barrel 2. A lead screw 4 is provided on one side of the outer wall of the material barrel 2. The lead screw 4 is rotatably connected to one end of the frame 1. A guiding base 5 is threadedly connected to the outer wall of the lead screw 4. The guiding base 5 is bolted to a connecting base 7 through a cylinder 6 provided at its bottom. One end of the connecting base 7 is rotatably connected to a driving gear 8. The driving gear 8 is meshed and connected with a driven gear 9. The driven gear 9 is integrally connected to the top of a baffle 10 through a shaft rod penetrating through its axis.

[0024] A telescopic bottom plate 701 is attached to the bottom of the connecting base 7. The output end of the cylinder 6 penetrates through the connecting base 7 and is bolted to the top of the telescopic bottom plate 701. The bottom of the telescopic bottom plate 701 is bolted with roller mounting brackets 702. The roller mounting brackets 702 are connected by a marking paint shaft 703. A marking roller 704 is provided between the roller mounting brackets 702. The marking paint shaft 703 penetrates through the marking roller 704 and the marking roller 704 is rotatably connected between the roller mounting brackets 702. The baffle 10 is attached to the bottom of the marking roller 704. One end of the marking paint shaft 703 is threadedly connected to an outer connecting head 705 of the material shaft. An inner connecting head 706 of the material shaft is provided inside the outer connecting head 705 of the material shaft.

[0025] In this embodiment, as Figure 1As shown, the top of the material bucket 2 is connected with a bucket cover by bolts, and one end of the stirring member 3 is integrally connected to the output end of the servo motor provided on the bucket cover at the top of the material bucket 2. The stirring member 3 is composed of a plurality of arc-shaped metal blades distributed in a ring shape. Since the marked paint is usually a mixture composed of multiple components, when stored in the material bucket 2, the densities of different components may vary, and precipitation is likely to occur. By continuously stirring with the stirring member 3, each component can always be kept in a uniformly mixed state, ensuring the consistency of the paint components when discharging from the material bucket 2, thereby ensuring the stable quality of the marked line.

[0026] In this embodiment, as Figure 2 shown, the material bucket 2 is made of a metal material with a double-layer structure, and a heating member 11 is annularly provided between the inner and outer layers of the material bucket 2. The outer wall of the material bucket 2 is electrically connected to the heating member 11 through the temperature controller provided thereon. At the same time, a storage battery 12 is installed at the bottom of the vehicle frame 1. The double-layer structure of the material bucket 2 can form a heat insulation layer to reduce the loss of internal heat. Combining the external temperature controller and the heating member 11 can maintain an appropriate temperature for the internal paint. Because the marked paint can maintain good fluidity within a certain temperature range. If the temperature is too low, the paint will become viscous and its fluidity will deteriorate, making it difficult to be evenly sprayed on the road surface through the spraying equipment. By reasonably adjusting the temperature, the construction process can be made smoother, and there is no influence caused by the season during winter construction.

[0027] In this embodiment, as Figure 3As shown, the guiding base 5 forms a horizontal transmission structure through the lead screw 4, and the marking roller 704 forms a lifting structure through the telescopic bottom plate 701 and the cylinder 6, and the marking roller 704 rolls along one end to the other end of the vehicle frame 1 through the guiding base 5; a structure for drawing lines is arranged below the guiding base 5, and through the horizontal transmission structure of the lead screw 4, compared with manually pushing the vehicle frame 1, this method can more accurately control the position and direction of the line drawing, play a role in positioning from the starting point to the end point. When drawing a straight line, it can ensure the straightness of the marking, improve the standardization and aesthetics of the road marking, reduce errors caused by human factors, and the transmission of the lead screw 4 has high stability, which can ensure the smoothness of the marking roller 704 during movement. This helps to evenly spray the paint on the road surface, avoid the situation of uneven thickness or missed coating, thereby improving the quality of the marking. Due to the certain transmission range limitation of the guiding base 5, when the marking roller 704 is transmitted to the limit position, the setting of its lifting structure can lift it and reset it through the transmission structure of the lead screw 4, which can break through the transmission range limitation of the guiding base 5 and continue the construction of the next stage. This helps to maintain the continuity of the construction, and the detachable structure of the roller mounting frame 702 and the telescopic bottom plate 701 is for replacing the specification of the marking roller 704. Because different road types and traffic demands have clear specifications for the marking width, in order to accurately draw a marking width that meets the standards and ensure the compliance of the road marking, the marking roller 704 is formed into a modular design through the roller mounting frame 702, and different specifications of the marking roller 704 can be flexibly configured according to different project requirements, improving the accuracy and standardization of the construction.

[0028] In this embodiment, as Figure 4 shown, the inside of the marking roller 704 is a hollow structure, and several through holes are distributed on the outer wall of the marking roller 704, and a liquid discharge port is opened at one end of the marking paint shaft 703 located inside the marking roller 704; the marking roller 704 is made of high-temperature resistant rubber material, and its internal hollow structure cooperates with the multiple through holes distributed on the outside, so that the paint can flow out evenly from multiple directions. When the marking roller 704 rolls on the road surface, the paint can contact the road surface in all directions, ensuring that the thickness of the marking is uniform and avoiding the situation of local over-thickness or under-thickness, improving the quality and aesthetics of the marking. The liquid discharge port at one end of the marking paint shaft 703 located inside the marking roller 704 can play a role in guiding the paint flow, and sealing gaskets can be arranged at both ends of the marking roller 704 penetrated by the marking paint shaft 703 to reduce the possibility of paint overflow.

[0029] In this embodiment, as Figure 1As shown in the figure, the connection between the marking paint shaft 703 and the outer connector 705 of the material shaft is hollow, and the inner connector 706 of the material shaft is inserted and connected to the hollow of the marking paint shaft 703. At the same time, its diameter is smaller than the inner diameter of the marking paint shaft 703. And the outer wall of the material barrel 2 is connected with a plunger pump through a pipeline. At the same time, one end of the inner connector 706 of the material shaft is connected to the other end of the plunger pump through a pipeline passing through the outer connector 705 of the material shaft. First of all, the outer connector 705 of the material shaft and the inner connector 706 of the material shaft are one of the main structures connecting the material barrel 2 and the marking roller 704. When it is necessary to replace the marking roller 704 of different specifications, it is first connected to the marking paint shaft 703 by means of threading and insertion, without complex disassembly and installation operations, and has a certain sealing effect.

[0030] In this embodiment, as Figure 4 and Figure 5 shown, the baffle 10 is arc-shaped and its specification is larger than the diameter of the marking roller 704. And a border is provided at one end of the baffle 10 that fits the marking roller 704. And the baffle 10 forms a flipping structure through the driving gear 8 and the driven gear 9. At the same time, a sponge is adhered to the inner wall of the baffle 10. The baffle 10 is arc-shaped and its specification is larger than the diameter of the marking roller 704, which can fully cover the marking roller 704 when the marking roller 704 is not in use, preventing excess paint from dripping onto the ground. This can keep the ground at the construction site clean and tidy, avoid paint pollution to the surrounding environment, and reduce the difficulty of subsequent cleaning work. Its border structure further enhances the interception effect. Its flipping structure is to avoid limiting the marking roller 704. When it is necessary to use the marking roller 704, the baffle 10 can be moved away through the transmission structure of the two groups of gears. And its sponge structure on the inner wall is realized by the bonding method of Velcro. Its inner wall uses the hook surface, and one side of the sponge uses the loop surface, which is convenient for disassembly, cleaning or replacement. The sponge can effectively adsorb excess paint. When the marking roller 704 is not in use, the sponge can catch the paint that may drip, avoiding the paint from directly dripping onto the ground. And when the marking roller 704 is used again, due to the adsorption effect of the sponge, there will be no situation where the paint picked up by the inner wall drips when the baffle 10 is moved away. In contrast, the current operation method is to lift the marking roller 704 with a pull rod and then move the vehicle frame 1. This method is not only cumbersome but also difficult to operate. In actual construction, it may take a lot of time and effort, affecting the construction efficiency. The flipping structure of the baffle 10 can be completed instantly, making the construction process smoother and more efficient.

[0031] The usage method and advantages of the present utility model: This marking device with a positioning function, when in use, the working process is as follows:

[0032] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 andFigure 5 As shown, first, during use, open the top cover of the paint bucket 2, pour the paint into it, cover the top cover with bolts, and turn on the power. The heating element 11 generates a certain amount of heat and maintains the temperature of the internal paint according to the temperature parameters set by the external temperature controller (AI-207). At the same time, the stirring member 3 continuously stirs under the action of the motor. It should be noted that in order to ensure the accuracy of the first marking, an idle thin surface partition can be placed in front of the position to be marked, so that the marking roller 704 rolls on the thin surface partition first and then enters the actual operation area. Since the paint appears for the first time and needs to be transported through the bellows, it provides a transition stage for the surface of the marking roller 704 to adhere to the paint. The construction worker pushes it to the construction point position through the handrail at one end of the vehicle frame 1, stops pushing, and turns on the power. First, the driving gear 8 rotates, driving the driven gear 9 to rotate. The top of the baffle 10 is connected to the shaft rod at the center of the driven gear 9, so that the baffle 10 rotates and moves away from under the marking roller 704. At the same time, the cylinder 6 pushes the telescopic bottom plate 701 to descend, so that the bottom of the marking roller 704 fits on the ground. At the same time, power is supplied to one side of the driving lead screw 4, the lead screw 4 rotates, and the guiding base 5 realizes linear transmission under the threaded structure and drives the bottom marking roller 704 to drive. Since the marking roller 704 is in rolling connection with the roller mounting frame 702 and the marking paint shaft 703, it rolls linearly under the driving structure. And the external plunger pump is transported through the liquid outlet on one side of the paint bucket 2 to the inner connector 706 of the material shaft through the bellows, converges to the cavity on one side of the marking paint shaft 703 by the inner connector 706 of the material shaft, and flows into the cavity inside the marking roller 704 through the drain port of the marking paint shaft 703 located inside the marking roller 704, and finally flows out from the through hole of the marking roller 704. When the maximum driving distance is reached, the cylinder 6 drives the telescopic bottom plate 701 to rise and reset again, and the driven gear 9 drives the baffle 10 to rotate in the reverse direction to fit under the marking roller 704 through the reverse rotation of the driving gear 8, and makes it reset through the driving of the lead screw 4 to start a new round of construction process. When marking a dotted line, multiple thin surface partitions can be arranged at equal distances. When the marking roller 704 passes over the road surface and the thin surface partitions one by one, the construction process of the dotted line can be completed. And the size of the marking roller 704 can be selected according to the construction specifications of the road surface marking. When replacing, the roller mounting frame 702 can be disassembled from under the telescopic bottom plate 701.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments.
