Description

Technical Field

[0001] This utility model belongs to the field of traffic engineering technology, and more specifically, it relates to a road marking removal device for traffic engineering. Background Technology

[0002] Road markings are an important component of highway traffic. However, these markings are constantly exposed to the natural environment, leading to severe corrosion and wear, requiring regular maintenance. This involves either repainting or scraping off the existing markings and repainting new ones. Removing road markings necessitates a traffic engineering marking removal device. Existing traffic engineering marking removal devices employ various methods, including milling, high-pressure water removal, grinding, and chemical dissolution. High-pressure water removal, in particular, is environmentally friendly, pollution-free, and does not damage the road surface, making it especially suitable for areas with high environmental protection requirements. It utilizes a high-pressure pump to generate high-pressure water, which is delivered through a hose to a nozzle. The high-pressure water is then sprayed at high speed onto the road markings, creating an impact force greater than the adhesion between the marking paint and the road surface, thus causing the marking paint to detach from the road surface.

[0003] This utility model, with application number CN202323325303.4, relates to the field of road engineering technology and discloses a road marking removal device for traffic engineering. It includes a frame and four wheels. A water tank is fixedly installed on the top right side of the frame. A traction side plate is fixedly installed on the top of the frame, to the right of the water tank. Two water pipes are connected to the right end of the water tank, and the other ends of the two water pipes are connected to a sprinkler plate. A fixed gantry is installed on the top left side of the frame. A movable gantry, which can be raised and lowered, is installed inside the fixed gantry. A grinding wheel is rotatably installed inside the movable gantry, and a large transmission wheel is sleeved on one end of the central shaft of the grinding wheel. This utility model, through the cooperation of the sprinkler plate and the grinding wheel, allows the device to be moved along the road markings by a towing vehicle. The sprinkler plate wets the markings, and the grinding wheel grinds and removes them. This design improves the efficiency of removing road markings and reduces dust generation during the grinding process.

[0004] Based on the above, existing traffic marking removal devices, when using high-pressure water to remove markings, are prone to causing injury due to the high pressure. Protective covers are typically installed around the nozzles. However, the height of these covers is mostly fixed. When encountering uneven road surfaces, the edges of the covers easily rub against the road surface, leading to wear. If the cover is set too high, high-pressure water can easily splash out, posing a safety hazard. Furthermore, during use, water quality issues may produce impurities such as mud, large particles, and scale, which can cause blockages and wear on the high-pressure nozzles. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a traffic marking removal device. This addresses the issue that existing traffic marking removal devices, when using high-pressure water to remove markings, are prone to causing injury due to the high pressure. Typically, a protective cover is installed around the nozzle. However, the height of existing protective covers is mostly fixed. When encountering uneven road surfaces, the edges of the cover easily rub against the road surface, leading to wear. If the protective cover is set too high, high-pressure water can easily splash out, posing a safety hazard. Furthermore, during use, water quality issues may produce impurities such as mud, large particles, and scale, which can cause blockages and wear on the high-pressure nozzle.

[0006] The purpose and effect of this utility model, a road marking removal device for traffic engineering, are achieved by the following specific technical means:

[0007] A road marking removal device for traffic engineering includes a road marking removal main body, a pressurizing mechanism, movable rollers, a telescopic handle, a corrugated protective cover, a water supply pipe, an adjustment component, and a maintenance component.

The telescopic handle is hinged to the rear side of the pressurizing mechanism. The top of the corrugated protective cover is fixedly installed at the bottom of the road marking removal main body. The adjustment component is disposed on the upper part of the road marking removal main body. The maintenance component is disposed in the middle of the water supply pipe.

[0008] Furthermore, the adjustment component includes a protective ring and movable ball bearings. The protective ring is fixedly connected to the bottom of the corrugated protective cover. Multiple sets of movable ball bearings are provided, and the multiple sets of movable ball bearings are rotatably connected to the bottom of the protective ring.

[0009] Furthermore, the adjustment component also includes: a limiting hole, a limiting pin, and a first elastic element. The limiting hole is provided in multiple sets, and the multiple sets of limiting holes are arranged in a circumferential array on one side of the pressurization mechanism. The limiting pin is slidably connected inside the hinge position of the telescopic handle. One end of the first elastic element is fixedly installed inside the hinge position of the telescopic handle, and the other end of the first elastic element is fixedly installed in the middle of the limiting pin.

[0010] Furthermore, the maintenance components include a filter box and a collection bottle. The filter box is fixedly installed in the middle of the water supply pipe. Two sets of collection bottles are provided, and the two sets of collection bottles are snapped onto the bottom sides of the filter box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this utility model has an adjustment component. The corrugated structure of the corrugated protective cover has a certain degree of elasticity. Under the elastic action of the corrugated protective cover, the protective ring is driven to fit tightly against the ground, protecting against high-pressure water. This allows the marking removal unit to be moved to a road surface with poor flatness, and also makes the corrugated protective cover suitable for different road surfaces. Moreover, the use of moving ball bearings reduces the wear caused by repeated friction of the protective ring against the road surface, greatly improving the protective effect. Furthermore, the length and angle of the telescopic handle can be adjusted, making it easy for different workers to adjust to a suitable position for use, greatly improving the flexibility of use.

[0016] Secondly, this utility model has a maintenance component. By turning the adjustment knob, the first filter plate and the second filter plate can be quickly replaced alternately, which avoids the blockage of one set of filter plates after long-term use. Moreover, the filter plates are scraped and cleaned during replacement, which greatly improves the replacement and maintenance efficiency and extends the service and maintenance cycle of the filter box.

[0017] This utility model has the advantages of high-efficiency protection, high applicability, and easy maintenance, which greatly improves the protection effect. It is also easy for different staff to adjust to a suitable position for use, and greatly improves the efficiency of replacement and maintenance, and extends the service and maintenance cycle of the filter box.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] Example 1:

[0029] As attached Figure 1 To be continued Figure 7 As shown:

[0030] This utility model provides a road marking removal device for traffic engineering, including a road marking removal body 1, a pressure boosting mechanism 2, movable rollers 3, a telescopic handle 4, a corrugated protective cover 5, a water supply pipe 6, and an adjustment component; the pressure boosting mechanism 2 is located inside the road marking removal body 1; the movable rollers 3 are installed on the left and right sides of the road marking removal body 1; the telescopic handle 4 is hinged to the rear side of the pressure boosting mechanism 2; the top of the corrugated protective cover 5 is fixedly installed at the bottom of the road marking removal body 1; and the adjustment component is located on the upper part of the road marking removal body 1.

[0031] The adjustment component includes a protective ring 501 and movable ball bearings 502. The protective ring 501 is fixedly connected to the bottom of the corrugated protective cover 5. Multiple sets of movable ball bearings 502 are provided, and multiple sets of movable ball bearings 502 are rotatably connected to the bottom of the protective ring 501.

[0032] The adjustment component also includes: a limiting hole 201, a limiting pin 401, and a first elastic element 402. Multiple sets of limiting holes 201 are provided, and multiple sets of limiting holes 201 are arranged in a circumferential array on one side of the pressurizing mechanism 2. The limiting pin 401 is slidably connected inside the hinge position of the telescopic handle 4. One end of the first elastic element 402 is fixedly installed inside the hinge position of the telescopic handle 4, and the other end of the first elastic element 402 is fixedly installed in the middle of the limiting pin 401.

[0033] The specific usage and function of this embodiment are as follows:

[0034] The corrugated structure of the corrugated protective cover 5 has a certain degree of elasticity. Under the elastic action of the corrugated protective cover 5, the corrugated protective cover 5 drives the protective ring 501 to stick to the ground, protecting against high-pressure water and avoiding safety hazards caused by high-pressure water splashing. Moreover, the bottom of the protective ring 501 has multiple sets of moving ball bearings 502 that rotate, so that the protective ring 501 is a certain distance from the ground, reducing the wear caused by repeated friction of the road surface, and also assisting the protective ring 501 in moving.

[0035] The telescopic handle 4 is a telescopic structure, fixed by bolt compression. When the telescopic handle 4 needs to be adjusted, pull the limiting pin 401. The limiting pin 401 is pulled out from the limiting hole 201 and compresses the first elastic element 402. At this time, the telescopic handle 4 can be swung to adjust it to a suitable angle. Then, release the limiting pin 401. Under the elastic action of the first elastic element 402, the limiting pin 401 is inserted into the limiting hole 201 to limit the telescopic handle 4, so that the telescopic handle 4 can be adjusted in length and angle, making it convenient for different workers to adjust it to a suitable position for use.

[0036] In this example, the structural principle of the booster mechanism 2 is existing technology, so it will not be described in detail.

[0037] Example 2:

[0038] Based on Example 1, such as Figures 1 to 7 As shown, it also includes a maintenance component, which is located in the middle of the water supply pipe 6.

[0039] The maintenance components include a filter box 601 and a collection bottle 602. The filter box 601 is fixedly installed in the middle of the water supply pipe 6. Two sets of collection bottles 602 are provided, and the two sets of collection bottles 602 are snapped into the bottom sides of the filter box 601.

[0040] The maintenance components also include: a threaded rod 6031, an adjusting knob 603, and a transmission plate 604. The threaded rod 6031 is rotatably connected inside the filter box 601; the adjusting knob 603 is fixedly installed at one end of the threaded rod 6031; the transmission plate 604 is slidably connected inside the filter box 601 and is threadedly connected to the outside of the threaded rod 6031.

[0041] The maintenance components also include: a first filter plate 6041 and a second filter plate 6042, wherein the first filter plate 6041 is installed inside the transmission plate 604; and the second filter plate 6042 is installed inside the transmission plate 604.

[0042] The maintenance components also include: a cleaning scraper 605 and a second elastic element 6051. There are two sets of cleaning scrapers 605, which are respectively hinged to each other on both sides inside the filter box 601. There are four sets of second elastic elements 6051, with each pair of second elastic elements 6051 installed on both sides of a set of cleaning scrapers 605.

[0043] The specific usage and function of this embodiment are as follows:

[0044] When the water inside the water storage device is transported to the pressurization mechanism 2 through the water supply pipe 6 for pressurized spraying, the water flows through the filter box 601. The first filter plate 6041 inside the filter box 601, which is directly opposite the water supply pipe 6, filters the water flow and reduces impurities from entering the pressurization mechanism 2.

[0045] When the first filter plate 6041 needs to be replaced after a period of use, turn the adjustment knob 603. The adjustment knob 603 drives the threaded rod 6031 to rotate. The rotation of the threaded rod 6031 drives the transmission plate 604 to slide inside the filter box 601 through the thread. This causes the transmission plate 604 to slide and drive the second filter plate 6042 to align with the water supply pipe 6, so that the first filter plate 6041 and the second filter plate 6042 can be quickly and alternately replaced.

[0046] When replacing the first filter plate 6041 and the second filter plate 6042, the second elastic element 6051, under the action of elastic torque, drives the cleaning scraper 605 to adhere to the surface of the transmission plate 604. When the transmission plate 604 slides inside the filter box 601, the first filter plate 6041, which is aligned with the water supply pipe 6, is not scraped off by the cleaning scraper 605 when it slides out due to the inclined structure of the cleaning scraper 605. The filter residue adheres to the first filter plate 6041. The surface of filter plate 6041 moves along with the first filter plate 6041 to one side of the inclined surface of cleaning scraper 605. The transmission plate 604 drives the second filter plate 6042 to slide to the position of water supply pipe 6. The inclined structure of cleaning scraper 605 scrapes the filter residue on the surface of the second filter plate 6042 to prevent the filter residue from entering the position of water supply pipe 6. The filter residue scraped off by cleaning scraper 605 falls into collection bottle 602 for storage. The filter residue inside collection bottle 602 is collected and cleaned by removing collection bottle 602.
