Description

Technical Field

[0001] The invention belongs to the technical field of traffic marking maintenance equipment, and in particular relates to a marking removing device for traffic engineering. Background Art

[0002] Hot melt paint has good wear resistance, good adhesion and high reflectivity. It is widely used for traffic markings on highways and main roads in cities with heavy traffic. Because traffic markings are exposed to the natural environment, even hot melt markings with strong wear resistance will continue to age and fall off, making traffic markings unclear and affecting traffic safety. For aging and falling traffic markings, it is necessary to remove them as a whole and then re-spray them. Otherwise, spraying directly on the old markings will cause the newly sprayed markings to have poor adhesion and easily fall off when vehicles pass by. In order to avoid affecting the passage of vehicles when removing the markings, it is necessary to quickly remove the markings on the road surface. When removing aging traffic markings, a shovel is generally used to shovel the markings off the ground, and then the removed markings are uniformly collected and processed for reuse. However, during the operation, it was found that because the aging speed of the bottom layer of the traffic markings is slower than that of the upper layer, the shovel cannot completely shovel the markings at one time, and it is necessary to scrape repeatedly, resulting in a slow removal speed of the traffic markings.

[0003] At present, in order to improve the speed of clearing traffic markings, a professional marking removal device is often used to be towed by an engineering vehicle to move along the markings to be cleared for rapid clearing operations. The marking removal device uses a heating component to heat the markings to make them melt and soften, thereby separating the markings from the road surface, and then sweeps the softened markings into a collection container through a roller brush, which can achieve rapid clearing of the markings. However, when using a roller brush to clean the softened markings, there is a phenomenon that the softened markings adhere to the roller brush. In response to this phenomenon, the existing marking removal devices are generally equipped with a scraper to clean the markings adhered to the roller brush, but the scraper can only remove the markings adhered to the end of the brush rod of the roller brush, while the markings located between the gaps between adjacent brush rods of the roller brush are difficult to clean. As the marking removal operation is continuously performed, the markings between adjacent brush rods will accumulate more and more, so that the markings accumulated between the brush rods are flush with the ends of the brush rods, and the brush rods are unable to sweep the softened markings into the collection container.

[0021] The present invention provides a marking removal device for traffic engineering, Figures 1 to 7 The present invention is described with reference to the structural schematic diagram of FIG.

[0022] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Traffic markings are an important part of traffic roads. They use various marking lines and symbols such as lines, arrows, text, facade markings, and contour marks to convey traffic information such as guidance, restrictions, and warnings, which can improve driving safety on traffic roads. Hot-melt coatings have good wear resistance, good adhesion, and high reflectivity. They are widely used for traffic markings on highways and main urban roads with heavy traffic. Because traffic markings are exposed to the natural environment, even hot-melt markings with strong wear resistance will continue to age and fall off, making traffic markings unclear and affecting traffic safety. For aging and falling traffic markings, they need to be removed as a whole and then re-sprayed. Otherwise, spraying directly on the old markings will cause the newly sprayed markings to have poor adhesion and easily fall off when vehicles pass by.

[0024] In order to avoid affecting the traffic when removing the markings, the markings on the road need to be removed quickly. When removing aged traffic markings, a shovel is generally used to remove the markings from the ground, and then the removed markings are collected and processed for reuse. However, during the operation, it was found that since the aging speed of the bottom layer of the traffic markings is slower than that of the upper layer, the shovel cannot completely remove the markings at one time, and it needs to be scraped repeatedly, resulting in a slow removal speed of the traffic markings.

[0025] At present, in order to improve the speed of clearing traffic markings, a professional marking removal device is often used to be towed by an engineering vehicle to move along the markings to be cleared for rapid clearing operations. The marking removal device uses a heating component to heat the markings to make them melt and soften, thereby separating the markings from the road surface, and then sweeps the softened markings into a collection container through a roller brush, which can achieve rapid clearing of the markings. However, when using a roller brush to clean the softened markings, there is a phenomenon that the softened markings adhere to the roller brush. In response to this phenomenon, the existing marking removal devices are generally equipped with a scraper to clean the markings adhered to the roller brush, but the scraper can only remove the markings adhered to the end of the brush rod of the roller brush, while the markings located between the gaps between adjacent brush rods of the roller brush are difficult to clean. As the marking removal operation is continuously performed, the markings between adjacent brush rods will accumulate more and more, so that the markings accumulated between the brush rods are flush with the ends of the brush rods, and the brush rods are unable to sweep the softened markings into the collection container.

[0026] Based on the above problems, an embodiment of the present invention provides a marking removal device for traffic engineering. By configuring a hot melt unit connected to the bottom of the engineering vehicle, the engineering vehicle can be moved along the marking to be cleaned, and the hot melt unit is used to heat the marking to soften it. The driving mechanism then drives the roller body to rotate around its circumference, so that the roller body drives the scraper to sweep the softened marking into the collecting bucket. When the softened marking adheres to the scraper teeth, when the scraper teeth pass through the tooth grooves of the comb plate, the comb plate is used to clean up all the markings adhered to the scraper teeth, thereby avoiding the scraper teeth from being affected by a large amount of solidified markings adhered to the scraper teeth, so that the scraper teeth can stably sweep the softened markings into the collecting bucket, thereby improving the convenience of traffic marking removal. The marking removal device of the present invention is easy to use, has good cleaning effect, is highly practical, and is worthy of promotion.

[0027] Reference Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a left side view of the cold compress device of this embodiment. Figure 2 is a front view of the cold compress device of this embodiment, Figure 3 FIG. 1 is a top view of the cold compress device of this embodiment. Figure 1 , Figure 2 and Figure 3 As shown, a marking line removal device for traffic engineering is configured and connected to an engineering vehicle to drive the removal device to move along the marking line for removal operation, including a hot melt unit and a cleaning unit. The hot melt unit is fixedly arranged at the bottom of the engineering vehicle to heat the marking line on the road surface to separate it from the road surface. The cleaning unit includes a collecting bucket 1, which is horizontally arranged at the bottom of the engineering vehicle and located at the side of the hot melt unit close to the tail of the engineering vehicle. The mouth of the collecting bucket 1 is arranged directly opposite to the hot melt unit. A roller body 2 is horizontally arranged at the collecting bucket 1 along the width direction of the engineering vehicle. The mouth of the collecting bucket 1, the roller body 2 is rotatably connected to the collecting bucket 1, the roller body 2 is connected to the output end of the driving mechanism to drive the roller body 2 to rotate, and multiple groups of scraping teeth 3 are radially connected to the roller body 2 so that the scraping teeth 3 can sweep the heated and softened marking line into the collecting bucket 1. The comb plate 4 is vertically arranged in the collecting bucket 1 and is parallel to the axis of the roller body 2. The comb plate 4 is located on the side of the roller body 2 away from the hot melt unit. The tooth grooves of the comb plate 4 are vertically downward and arranged one by one with the scraping teeth 3 to clean up the marking line adhered to the scraping teeth 3.

[0028] The embodiment proposes a marking line removing device for traffic engineering, which can process the marking lines to be removed on the road surface. The device is configured and installed on an engineering vehicle. The engineering vehicle moves along the marking lines to be removed (usually moves forward according to the vehicle driving rules), and uses a hot melt unit to heat the marking lines directly below it, so that the marking lines are softened by heat and automatically separated from the road surface. Then, the driving mechanism drives the roller body 2 to rotate, so that the scraping teeth 3 on the roller body 2 push the softened marking lines into the collecting bucket 1, so as to achieve the removal of the road marking lines. When the softened marking lines adhere to the scraping teeth 3, the tooth grooves of the comb plate 4 are used to remove the marking lines adhered to the scraping teeth 3, so as to avoid the accumulation of marking lines adhering to adjacent scraping teeth 3 when removing the marking lines, and avoid the situation where the scraping teeth 3 cannot sweep the softened marking lines into the collecting bucket 1, thereby improving the convenience of traffic marking line removal.

[0029] The hot melt unit in the above embodiment can be: an electric heating plate or a gas spray gun and other components, the part of the electric heating plate or the gas spray gun that outputs heat needs to face downward directly to the road surface, so that the output heat can quickly soften the markings on the road surface.

[0030] The driving mechanism in the above-mentioned embodiment includes a motor 7 and two mutually meshing gears 71. The motor 7 is fixed on the collecting bucket 1, one of the gears 71 is mounted on the output shaft of the motor 7, and the other gear 71 is mounted on the roller body 2, so that the motor 7 drives the roller body 2 to rotate. The motor 7 is connected to an external controller and a power supply, so that the operator can control it conveniently.

[0031] As a further optimization scheme, in this embodiment, the interior of the roller body 2 is hollow, one end of the scraper 3 extends into the interior of the roller body 2, and the scraper 3 is slidingly connected to the roller body 2 along the radial direction of the roller body 2. A linear displacement mechanism is provided on the roller body 2, and the output end of the linear displacement mechanism is connected to the scraper 3 for driving the scraper 3 to move back and forth.

[0032] In this embodiment, a hollow roller body 2 is used to enable the scraper teeth 3 to be slidably connected to the roller body 2 along the radial direction, and then the scraper teeth 3 can move back and forth through a linear displacement mechanism. When the scraper teeth 3 pass through the tooth grooves of the comb plate 4, the scraper teeth 3 can move back and forth to facilitate the cleaning of the markings adhered thereto, further preventing the softened markings from adhering to and solidifying on the scraper teeth, thereby improving the convenience of removing traffic markings.

[0033] Reference Figure 5 and Figure 7 , Figure 5 This is the AA cross-sectional view of the cold compress device of this embodiment. Figure 7 FIG. 2 is a cross-sectional view of the cold compress device of this embodiment. Figure 5 and Figure 7As shown, as a further optimization scheme, the linear displacement mechanism in this embodiment includes a cylinder 5 and a plurality of traction members 6. The cylinder 5 is coaxially inserted into the roller body 2 and is rotatably connected thereto. Both ends of the cylinder 5 are fixedly connected to the inner wall of the collecting bucket 1. One end of the scraper 3 abuts against the cylinder 5. An arc-shaped groove 51 is provided on one side of the cylinder 5 and is located on the side of the cylinder 5 away from the collecting bucket 1. The traction member 6 is connected between the roller body 2 and the scraper 3, and is used to drive the scraper 3 to move toward the direction close to the center line of the cylinder 5.

[0034] This embodiment provides a specific structure of a linear displacement mechanism, through the use of an arc groove 51 on the cylinder 5 and a plurality of traction members 6, so that one end of the scraper 3 is always in contact with the cylinder 5, and when the roller body 2 rotates, the scraper 3 is synchronously driven to rotate, and when the scraper 3 passes through the arc groove 51 on the cylinder 5, it moves back and forth, so that the scraper 3 cooperates with the tooth grooves of the comb plate 4 to remove the marking line adhered to the scraper 3, and then the scraper 3 automatically moves back and forth when passing through the comb plate 4, which not only ensures the stability of the marking line cleaning, but also maintains stability at other positions, so that the softened marking line on the ground can be stably swept into the collecting bucket 1.

[0035] Reference Figure 6 , Figure 6 FIG. BB is a cross-sectional view of the cold compress device of this embodiment. Figure 6 As shown, as a further optimization scheme, in this embodiment, a guide rod 31 is provided at one end of the scraper 3 and is parallel to the scraper 3, one end of the guide rod 31 is fixedly connected to the scraper 3, and the other end extends into the interior of the roller body 2 and is slidably connected thereto, and the other end of the guide rod 31 abuts against the cylinder 5.

[0036] In this embodiment, a guide rod 31 is provided at one end of the middle scraper 3, and the guide rod 31 is used to drive the scraper 3 to move back and forth, so as to improve the stability of the scraper 3 moving back and forth when passing through the arc groove 51 on the cylinder 5. At the same time, the outer diameter of the guide rod 31 is smaller than the scraper 3, so as to prevent the debris of the marking line from entering the interior of the roller body 2, so as to ensure the stability of the guide rod 31 sliding on the cylinder 5.

[0037] As a further optimization scheme, in this embodiment, a mounting seat 32 is fixedly provided at one end of the guide rod 31 close to the cylinder 5, and a groove is opened on the side of the mounting seat 32 close to the cylinder 5. A roller 33 is rotatably connected to the groove. The roller 33 and the center line of the cylinder 5 are parallel to each other, and the roller 33 abuts against the outer side of the cylinder 5.

[0038] In this embodiment, the mounting seat 32 is used to make the roller 33 rotatably connected to the guide rod 31, thereby improving the stability of the guide rod 31 moving on the cylinder 5 and avoiding the situation of being stuck.

[0039] As a further optimization solution, in this embodiment, the lower side of the comb teeth of the comb plate 4 is arc-shaped, and the arc is coaxial with the center line of the roller body 2.

[0040] In this embodiment, the lower side of the comb teeth of the comb plate 4 is arranged to be arc-shaped, which can increase the time for the scraper teeth 3 to pass through the comb plate 4 and further improve the effect of cleaning the marking line adhered to the scraper teeth 3.

[0041] Reference Figure 4 , Figure 4 This is a right side view of the cold compress device of this embodiment. Figure 4 As shown, as a further optimization solution, in this embodiment, the gap between adjacent comb teeth of the comb plate 4 gradually decreases from bottom to top.

[0042] In this embodiment, the gap between adjacent comb teeth is gradually reduced from bottom to top, so that the scraping teeth 3 can smoothly enter the tooth grooves of the comb plate 4. As the gap between the tooth grooves continues to decrease, not only the marking lines adhered between adjacent scraping teeth 3 can be cleaned up, but also the marking lines adhered to the ends of the scraping teeth 3 can be cleaned up, thereby gradually removing the marking lines adhered to the scraping teeth 3.

[0043] As a further optimization solution, in this embodiment, the length of the lower side of the mouth of the collecting bucket 1 is smaller than the length of the upper side thereof.

[0044] In this embodiment, the mouth of the collecting bucket 1 which is longer at the lower end is utilized, so that the roller body 2 is arranged on the upper side of the mouth of the collecting bucket 1, so that the scraping teeth 3 on the roller body 2 sweep the softened marking line into the collecting bucket 1, and a conveyor belt is provided on the lower side of the collecting bucket 1 away from its mouth, so as to transport the marking line entering the collecting bucket 1 to its bottom.
