Description

Technical Field

[0001] This utility model relates to the field of road marking technology, specifically a push-type road marking device. Background Technology

[0002] In modern transportation systems, road markings serve as crucial facilities for guiding traffic flow and regulating driving behavior. Their clarity and standardization directly impact road efficiency and driving safety. Whether it's urban arterial roads, highways, or roads within residential areas, lane lines, zebra crossings, stop lines, and other markings are painted on the road surface using marking devices. These markings not only provide clear driving guidance for drivers but also ensure the safety of pedestrians crossing the street.

[0003] According to a search, Chinese patent document CN220550428U discloses a road marking device. In use, a stirring component continuously stirs the marking paint to maintain its optimal state. A cleaning component cleans the surface before the marking is applied using a spraying component. After spraying, a marking drying component immediately dries the markings, effectively removing dust and debris from the road surface, improving the smoothness of the lines, reducing the possibility of damage, and extending the markings' lifespan. The immediate drying process prevents the markings from being easily damaged by other factors while still wet.

[0004] However, the above-mentioned line marking device still has the following defects in practical application: it lacks a structure for adjusting the material discharge, which makes it impossible to achieve intermittent line marking, while it is often necessary to draw dashed lines on the road, which limits its functionality. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a push-type road marking device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a push-type road marking device, comprising a side plate, a shaft rotatably connected inside the side plate, a frame rotatably connected to the outer surface of the shaft rotatably, a second shaft rotatably connected inside the frame, a rubber roller clamped to the outer surface of the first shaft, a roller brush rotatably connected to the outer surface of the second shaft, a pulley fixedly connected to the outer wall of the side plate, a steel wire rope slidably contacting the outer surface of the pulley rotatably, a pull rod fixedly connected to one end of the steel wire rope, and the outer surface of the pull rod... A spring is fitted onto the side plate, and an arc groove is formed through the outer wall of the side plate. A collar is rotatably connected to the outer wall of the side plate, and a first limiting hole plate is fixedly connected to the outer wall of the side plate. A pulley two slides on the outer surface of the wire rope, and a lifting rod is fixedly connected to the other end of the wire rope. A connecting rod is bolted to the outer wall of the side plate, and an ear plate is fixedly connected to one end of the connecting rod. A top plate is fixedly connected to the top surface of the ear plate, and a push plate is fixedly connected to the top surface of the top plate. A second limiting hole plate is fixedly connected to the outer wall of the push plate.

[0007] As described above, a paint bucket is connected to the top surface of the top plate by screws. A suction pipe is installed inside the paint bucket. One end of the suction pipe is connected to the suction end of a gear pump, and a hose is connected to the output end of the gear pump.

[0008] As described above, a geared motor is connected to the outer wall of the side plate by screws. The output shaft of the geared motor is fixedly connected to a synchronous pulley one. The synchronous pulley one is driven by a synchronous belt. The synchronous belt is driven by a synchronous pulley two. A shaft one is fixedly connected to the center of the end face of the synchronous pulley two. A coupling is fixedly connected to the center of the end face of the synchronous pulley one. One end of the coupling is connected to a rotating rod. Both ends of the rotating rod are fixedly connected to movable wheels. A hoop is connected to the top surface of the top plate by screws. A storage battery is installed inside the hoop.

[0009] As described above, a friction wheel is fixedly connected to the outer wall of the rotating rod, the friction wheel rubs against the measuring wheel, and an encoder is connected to the end face of the measuring wheel.

[0010] As described above, a paint discharge pipe is inserted into the end of the hose away from the gear pump. A lug is bolted to the outer wall of the paint discharge pipe. A round rod is slidably connected inside the lug, and a knob is threaded to the outer wall of the lug.

[0011] As mentioned above, the rubber roller and the roller brush are of the same length, and the frame includes a C-shaped plate and a front end plate, with the front end plate being bolted to one side of the C-shaped plate.

[0012] As described above, two push plates are fixedly connected to the top surface of the top plate, and a push rod is fixedly connected between the two push plates. A straight groove is opened through the outer wall of the two push plates, and a lifting rod is slidably connected in the straight groove. A controller is fixedly connected to the outer wall of the push rod, and a digital display screen is installed on the top surface of the controller.

[0013] As described above, a pull rod is inserted into the outer wall of the second shaft near one end, one end of the spring abuts against the second shaft, and the other end of the spring abuts against the collar, the wire rope is inserted into the holes of the first and second limiting holes, and the wheel frame of the second pulley is fixedly connected to the top of the top plate.

[0014] Compared with existing technologies, this push-type road marking device has the following advantages:

[0015] I. This utility model achieves convenient separation and contact between the roller brush and the road surface through a clever mechanical structure. When the lifting rod is pulled upward, the wire rope pulls the pull rod under the guidance of the pulley, causing the second shaft and the frame to rotate around the first shaft, compressing the spring and lifting the roller brush off the road surface. After the lifting rod is released, the spring returns to its original position and pushes the roller brush to contact the road surface again. This process is simple to operate. With the start and stop of the gear pump, the discontinuity of the line drawing can be precisely controlled to meet the needs of drawing dotted lines. The working state can be switched without complicated operation, which greatly improves the flexibility and applicability of line drawing.

[0016] II. This utility model uses a rotating rod to drive a friction wheel to rotate, which in turn drives a meter wheel to rotate. The encoder converts the mechanical rotation into an electrical signal and transmits it to a digital display screen, showing the distance traveled in real time. Based on the data on the digital display screen, combined with the preset dashed line segments and interval lengths, workers can accurately control the drawing rhythm, ensuring that the dimensions of each part of the dashed line are consistent. This avoids errors caused by manual distance estimation, ensuring the standardization and accuracy of the drawing. Especially in scenarios such as road markings where dimensional accuracy is required, it significantly improves the construction quality.

[0024] 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.

[0025] like Figures 1-5As shown, this utility model provides a technical solution: a push-type road marking device, including a side plate 1, a shaft 2 rotatably connected inside the side plate 1, a frame 3 rotatably connected to the outer surface of the shaft 2, a second shaft 4 rotatably connected inside the frame 3, a rubber roller 5 clamped to the outer surface of the shaft 2, a roller brush 6 rotatably connected to the outer surface of the second shaft 4, a pulley 7 fixedly connected to the outer wall of the side plate 1, a steel wire rope 8 slidingly contacting the outer surface of the pulley 7, a pull rod 9 fixedly connected to one end of the steel wire rope 8, and a spring 10 sleeved on the outer surface of the pull rod 9. An arc groove 11 is provided through the outer wall of the side plate 1. A collar 12 is rotatably connected to the outer wall of the side plate 1. A first limiting hole plate 13 is fixedly connected to the outer wall of the side plate 1. A pulley 14 slides in contact with the outer surface of the wire rope 8. A lifting rod 15 is fixedly connected to the other end of the wire rope 8. A connecting rod 16 is bolted to the outer wall of the side plate 1. An ear plate 17 is fixedly connected to one end of the connecting rod 16. A top plate 18 is fixedly connected to the top surface of the ear plate 17. A push plate 19 is fixedly connected to the top surface of the top plate 18. A second limiting hole plate 20 is fixedly connected to the outer wall of the push plate 19.

[0026] like Figures 1-2 As shown, a paint bucket 21 is connected to the top surface of the top plate 18 by screws. A suction pipe 22 is installed inside the paint bucket 21. One end of the suction pipe 22 is connected to the suction end of the gear pump 23, and the output end of the gear pump 23 is connected to a hose 24.

[0027] A geared motor 25 is connected to the outer wall of the side plate 1 by screws. The output shaft of the geared motor 25 is fixedly connected to a synchronous pulley 26. The synchronous pulley 26 is connected to a synchronous belt 27. The synchronous belt 27 is connected to a synchronous pulley 28. The end face center of the synchronous pulley 28 is fixedly connected to a shaft 2. The end face center of the synchronous pulley 26 is fixedly connected to a coupling 29. One end of the coupling 29 is connected to a rotating rod 30. Both ends of the rotating rod 30 are fixedly connected to movable wheels 31. The top surface of the top plate 18 is connected to a hoop by screws. A storage battery is installed inside the hoop.

[0028] By setting up a storage battery, power can be provided to the geared motor 25 and the gear pump 23. When the geared motor 25 is started, it can drive the synchronous pulley 26 to rotate. The synchronous pulley 26 drives the coupling 29 to rotate, the coupling 29 drives the rotating rod 30 to rotate, and the rotating rod 30 drives the moving wheels 31 at both ends to rotate. At this time, the operator can drive the top plate 18 to move by using the auxiliary push rod in conjunction with the push plate 19, which in turn can drive the entire line drawing device to move. In this way, there is no need for continuous manual pushing force during the line drawing process. Only manual support of the push rod is needed to determine the direction of movement of the device, making the operation simple and labor-saving.

[0029] like Figure 3 As shown, a friction wheel 32 is fixedly connected to the outer wall of the rotating rod 30. The friction wheel 32 rubs against the measuring wheel 33, and an encoder 34 is connected to the end face of the measuring wheel 33.

[0030] The rotation of the rotating rod 30 drives the friction wheel 32 to rotate, which in turn drives the measuring wheel 33 to rotate.

[0031] When the rotating rod 30 rotates, it drives the friction wheel 32 to rotate. The friction wheel 32 rubs against the measuring wheel 33 and drives it to rotate. The rotation of the measuring wheel 33 is transmitted to the encoder 34. The encoder 34 converts the mechanical rotation into an electrical signal and transmits it to the digital display screen 40 through wires. The digital display screen 40 then displays the distance the line drawing device has moved in real time. This mechanism is crucial for drawing dashed lines on roads. Workers can accurately control the line drawing rhythm based on the real-time distance displayed on the digital display screen 40, combined with the preset dashed line segment length and interval length. When the moving distance reaches the preset segment length, the roller brush 6 can be removed from the road surface by operating the lifting rod 15 and other structures, and the gear pump 23 can be stopped from feeding, thus breaking the line drawing. When the moving distance reaches the preset interval length, the roller brush 6 is restored to contact with the road surface, and the gear pump 23 resumes feeding to continue drawing the line. In this way, the size consistency of each dashed line segment and interval can be strictly guaranteed, avoiding errors caused by manual distance estimation, and ensuring that the drawn dashed lines meet the specifications.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the end of the hose 24 away from the gear pump 23 is connected to a paint discharge pipe 35. The outer wall of the paint discharge pipe 35 is connected to a lug 36 by bolts. A round rod 37 is slidably connected inside the lug 36, and a knob 38 is threadedly connected to the outer wall of the lug 36.

[0033] The rubber roller 5 and the roller brush 6 are of the same length. The frame 3 includes a C-shaped plate and a front end plate, and the front end plate is bolted to one side of the C-shaped plate.

[0034] After disassembling the front panel of frame 3, the rubber roller 5 can be removed from shaft 1 2, and the roller brush 6 can be removed from shaft 2 4. This allows for the replacement of rubber rollers 5 and roller brushes 6 of different lengths, thus adjusting the width of the line as needed. Simultaneously, when the knob 38 is loosened, the lug 36 can slide on the round rod 37, adjusting the position of the paint discharge pipe 35 to maintain it at the midpoint between the rubber roller 5 and the roller brush 6. When drawing lines on the road surface, the gear pump 23, in conjunction with the suction pipe 22, draws paint from the paint bucket 21. The paint then enters the hose 24 and finally exits from the paint discharge pipe 35, dripping onto the area between the rubber roller 5 and the roller brush 6. Since the roller brush 6 can contact the road surface, and because... After the geared motor 25 drives the synchronous pulley 26 to rotate, it can also drive the synchronous pulley 28 to rotate in conjunction with the synchronous belt 27. In this way, the synchronous pulley 28 drives the shaft 2 to rotate, and the shaft 2 drives the rubber roller 5 to rotate. Since the rubber roller 5 is tangent to the circumference of the roller brush 6 and has the same length, it can evenly transfer the paint to the surface of the roller brush 6 through contact, providing the roller brush 6 with a continuous and appropriate amount of paint. At the same time, the rotation of the rubber roller 5 can drive the roller brush 6 to rotate synchronously, so that when the roller brush 6 contacts the road surface, it can evenly spread the paint on the road surface to form a continuous and flat marking line, ensuring the uniformity and continuity of the marking line, avoiding paint accumulation or uneven application, and improving the quality of the road marking.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, two push plates 19 are fixedly connected to the top surface of the top plate 18, and a push rod is fixedly connected between the two push plates 19. A straight groove is opened through the outer wall of the two push plates 19, and a lifting rod 15 is slidably connected in the straight groove. A controller 39 is fixedly connected to the outer wall of the push rod, and a digital display screen 40 is installed on the top surface of the controller 39.

[0036] A pull rod 9 is inserted into the outer wall of shaft 2 4 near one end. One end of spring 10 abuts against shaft 2 4, and the other end of spring 10 abuts against collar 12. Wire rope 8 is inserted into the holes of first limiting hole plate 13 and second limiting hole plate 20. The wheel frame of pulley 2 14 is fixedly connected to the top of top plate 18.

[0037] When the lifting rod 15 is pulled upwards, the steel wire rope 8, which is fixedly connected to it, moves under the guidance of pulley 7 and pulley 14. The other end of the steel wire rope 8 pulls the tie rod 9. Since the tie rod 9 is inserted into the outer wall of the shaft 4 and the shaft 4 is rotatably connected to the frame 3, the tie rod 9, under force, will drive the shaft 4 and the frame 3 to rotate around the shaft 2. At this time, the spring 10 in the collar 12 is compressed. As the frame 3 rotates, the roller brush 6 on the outer surface of the shaft 4 will gradually move upwards. The roller brush 6 is lifted up, and at the same time, the second shaft 4 slides in the arc groove 11 until the roller brush 6 is separated from the road surface, thus realizing the separation of the roller brush 6 from the road surface. During this process, the first limiting hole plate 13 and the second limiting hole plate 20 limit the steel wire rope 8 to ensure its stable movement trajectory. When the roller brush 6 falls off the road surface, it cannot form lines on the road surface, thus failing to meet the requirement of drawing dotted lines. Once the lifting rod 15 is released, the spring 10 abuts against the second shaft 4 to reset it, thereby driving the roller brush 6 to re-contact the road surface.

[0038] Working principle: First, check the battery power to ensure it can supply power to the geared motor 25 and gear pump 23. Based on the required line width, replace the appropriate length of the rubber roller 5 and brush 6 by disassembling the front plate of frame 3, and pour the paint into paint bucket 21, ensuring the suction pipe 22 can properly draw in the paint. Then, start the geared motor 25, which drives the first synchronous pulley 26 to rotate, which in turn drives the moving wheel 31 to rotate via coupling 29 and rotating rod 30. Simultaneously, the first synchronous pulley 26 drives the second synchronous pulley 28 to rotate via synchronous belt 27, causing shaft 2 and rubber roller 5 to rotate. Rubber roller 5 drives the brush 6 to rotate synchronously. Start the gear pump 23, which draws paint from paint bucket 21 through suction pipe 22, dripping it between rubber roller 5 and brush 6 through hose 24 and paint discharge pipe 35. Next, the operator supports the push rod and uses push plate 19 to control the movement direction of the device, which moves under the action of the moving wheel 31. The roller brush 6 evenly spreads paint on the road surface to form a marking. At the same time, the rotating rod 30 drives the friction wheel 32 to rotate, and the friction wheel 32 drives the measuring wheel 33 to rotate. The encoder 34 converts the rotation into an electrical signal and transmits it to the digital display screen 40 to display the moving distance in real time. When drawing a dotted line, when the digital display screen 40 shows that the moving distance has reached the preset line segment length, the lifting rod 15 is pulled upward. Through the wire rope 8 and the pull rod 9, the shaft 2 4 and the frame 3 are driven to rotate around the shaft 2, compressing the spring 10, so that the roller brush 6 is lifted off the road surface. At the same time, the gear pump 23 is controlled to stop feeding and stop drawing lines. When the moving distance reaches the preset interval length, the lifting rod 15 is released, the spring 10 pushes the shaft 2 4 to reset, and the roller brush 6 re-contacts the road surface. At the same time, the gear pump 23 is started to resume feeding and continue drawing lines. After the line drawing is completed, the reduction motor 25 and the gear pump 23 are turned off, the residual paint on the device is cleaned, and the status of each component is checked.
