Description

Technical Field

[0001] The invention relates to the field of road clearing, and in particular to a road marking clearing device. Background Art

[0002] Road marking removal refers to the process of completely removing the original marking material when maintaining or re-marking the road. This step is crucial to ensure the clarity and adhesion of the new markings.

[0003] In the prior art, high-pressure water jets are used to remove road markings. The high-speed water flow generated by the high-pressure water gun is used to wash away the marking materials. Then, a large amount of water is required to remove road markings using the high-pressure water jet. When a large amount of water accumulates on the road, it may affect traffic, and the use of a large amount of water causes a waste of water resources. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a road marking removal device.

[0005] In a first aspect, the present invention provides a road marking removal device, comprising a base, a plurality of universal wheels are mounted on the bottom of the base, and further comprising:

[0006] A bottom plate, fixed to the bottom of the inner cavity including the base;

[0007] A barrel body, fixed to the top of the base;

[0008] A high-pressure cleaning component, installed between the base and the barrel, for high-pressure cleaning of road markings;

[0009] The negative pressure recovery component is arranged in a frame shape, and the high pressure removal component is located inside the frame of the negative pressure recovery component, and is used to recover the water flow sprayed out by the high pressure removal component at high pressure;

[0010] The interception component is arranged in a frame shape, and the negative pressure recovery component is located inside the frame of the interception component, and is used to dynamically intercept the water flow generated by the high-pressure cleaning component when starting, so as to assist the high-pressure cleaning component in recovering the water flow;

[0011] When it is necessary to clear the road markings, the base moves above the road markings through the universal wheels at the bottom. At this time, the high-pressure cleaning component is started, and the high-pressure cleaning component sprays the water flow inside the barrel at high pressure. The sprayed high-pressure water flow will clear the road markings. At the same time, the sprayed high-pressure water flow flows along the road surface. The set intercepting component can intercept the flowing water flow, so that the water flow can be kept inside the intercepting component in a dynamic state, which is conducive to avoiding the situation where the water flow flows along the road after flowing out and is difficult to gather for recovery. Subsequently, the negative pressure recovery component performs negative pressure recovery on the intercepted water flow, so that after the road markings are cleared by the high-pressure water flow, the water flow used for clearing the road markings can be recovered, which is conducive to avoiding the situation where the water flow accumulates on the road and causes the road to be slippery, thereby causing a safety hazard. In addition, by recycling the water flow, it is conducive to avoiding the waste of water flow, which is conducive to saving water resources.

[0012] Preferably, the high pressure removal assembly comprises:

[0013] A high-pressure spray gun is fixedly mounted on the bottom of the base plate, and the high-pressure spray gun is arranged flat;

[0014] A first water pump, fixedly installed inside the barrel;

[0015] A first connecting pipe, one end of which is fixedly connected to the water outlet of the first water pump, and the other end of which is fixedly connected to the high-pressure spray gun;

[0016] After the first water pump is started, the water flow inside the barrel is transported to the first connecting pipe, and the first connecting pipe transports the water flow to the high-pressure spray gun. The high-pressure spray gun sprays the water flow at high pressure, so that the road markings are cleared by the high-pressure sprayed water flow. The flat-arranged high-pressure spray gun can make the sprayed high-pressure water flow appear flat, thereby increasing the cleaning range of the high-pressure water flow sprayed by the high-pressure spray gun, which is beneficial to improving the cleaning efficiency of the road markings.

[0017] Preferably, the negative pressure recovery component comprises:

[0018] A plurality of negative pressure suction ports are arranged in an array, and all of the negative pressure suction ports are surrounded to form a frame shape;

[0019] A connection box is fixed to the top of the connection box, and all the negative pressure suction ports are connected to the connection box;

[0020] a partition fixed inside the barrel body, the partition dividing the barrel body into a water tank and a recovery tank, and the first water pump is located inside the water tank;

[0021] A plurality of second water pumps, all fixed inside the recovery tank;

[0022] A plurality of second connecting pipes, arranged corresponding to the second water pumps, one end of which is fixedly connected to the input end of the corresponding second water pump, and the other end of which is fixedly connected to the connecting box;

[0023] After the second water pump is started, the water accumulated on the road is transported to the inside of the recovery box through the negative pressure suction port. By setting up multiple second water pumps, it is beneficial to increase the suction force of the negative pressure suction port on the water flow, thereby facilitating the improvement of the recovery rate of the water flow;

[0024] The barrel body is divided into a water tank and a recovery tank by a partition, so that the water flow that needs high-pressure cleaning is separated from the recycled sewage, which helps to prevent the recycled sewage from entering the interior of the water tank and causing stone particles in the sewage to enter the interior of the water tank and affect the use of the high-pressure spray gun.

[0025] Preferably, the negative pressure recovery component further comprises:

[0026] a third water pump, fixed inside the recovery tank;

[0027] A water inlet pipe, one end of which is fixed to the input end of the third water pump and the other end of which is connected to the recovery tank;

[0028] A water outlet pipe, one end of which is fixed to the output end of the third water pump, and the other end of which passes through the partition and is connected to the water tank;

[0029] A filter plate is fixed inside the recovery box, and the other end of the water inlet pipe is located above the filter plate;

[0030] The filter plate is arranged inside the recovery box. When the second water pump transports the recovered sewage to the inside of the recovery box, the water outlet end of the second water pump is located below the filter plate, so that the recovered sewage is transported to the space below the filter plate for accumulation. When the recovered sewage gradually accumulates and overflows the filter plate, the water flow can be filtered, so that all impurities contained in the recovered sewage are stored in the position below the filter plate, and the position above the filter plate is the filtered water flow. After the third water pump is started, the filtered water flow above the filter plate enters the interior of the water tank along the path of the water inlet pipe, the water inlet pipe and the water outlet pipe, so that the recovered sewage can be reused, which is beneficial to prolong the high-pressure flushing and cleaning time of the road markings by the device each time, and is beneficial to reduce the waste of water flow.

[0031] Preferably, the negative pressure recovery component further comprises:

[0032] A mesh sleeve is fixed to the bottom of the bottom plate, and the negative pressure suction ports are all located inside the mesh sleeve;

[0033] By setting the mesh sleeve, when the negative pressure suction port absorbs water flow, the stone particles contained in the water flow can be blocked by the mesh sleeve, which is helpful to avoid the stone particles being recovered together with the negative pressure to cause blockage.

[0034] Preferably, the interception component comprises:

[0035] Four roller brushes are distributed in a frame shape, and first bevel gears are coaxially fixed at both ends of the four roller brushes, and adjacent first bevel gears are meshed with each other;

[0036] Four arc-shaped plates are fixed on the top of the bottom plate, and form a rolling space for the roller brush between the bottom plate and the bottom plate;

[0037] Four protection boxes are fixed through the top of the bottom plate, and two meshed first bevel gears form a group, and the first bevel gears in the same group are located inside the same protection box;

[0038] A driving assembly, mounted on the top of the base plate, for driving one of the first bevel gears to rotate;

[0039] After the driving component is started, the roller brush is driven to rotate, and the roller brushes are driven to rotate mutually through the first bevel gear. The rotation direction of the roller brush is toward the negative pressure recovery component, so that the rotating roller brush can play a role of brushing and sweeping the water flowing on the ground, pushing the water flow to accumulate in the direction of the negative pressure recovery component, which is conducive to the water flow being recovered by the negative pressure recovery component;

[0040] The arc plate and the protection box can protect the roller brush and the first bevel gear, so that when the roller brush brushes the water, it will not drive the water flow into the space above the bottom plate to cause damage to the internal parts. The protection box can separate the first bevel gear from the water, which helps to reduce the damage to the first bevel gear.

[0041] Preferably, the interception component further comprises:

[0042] A plurality of brushes are arranged in a linear array, and all of the brushes are arranged in a frame-shaped array;

[0043] The high-pressure spray gun is located inside the frame of the brush;

[0044] The brush can form an isolation layer between the negative pressure recovery component and the high-pressure cleaning component, so that when the high-pressure cleaning component sprays water at high pressure, the reflected water flow formed after the high-pressure sprayed water flow impacts the road can be blocked by the brush, and the impact force of the water flow is removed after being blocked by the brush, which is beneficial to avoid the situation where the water flow has a strong impact force and breaks through the roller brush to flow outward in large quantities. The water flow can pass through the brush and then flow between the brush and the roller brush. Under the rolling brushing action of the roller brush, it is accumulated and recovered by the negative pressure recovery component, which is beneficial to improve the recovery rate of the water flow.

[0045] Preferably, the drive assembly comprises:

[0046] A support plate, fixed to the top of one of the protection boxes;

[0047] A first motor is fixed on the top of the first motor, an output shaft of the first motor passes through the support plate and is fixed with a second bevel gear, the second bevel gear is meshed with one of the first bevel gears;

[0048] The support plate can fix the first motor. After the first motor is started, the output shaft drives the second bevel gear connected thereto to rotate, and the second bevel gear drives the first bevel gear meshing therewith to rotate, thereby realizing the rotation drive of the first bevel gear.

[0049] Preferably, it also includes:

[0050] A camera, fixed to the bottom of the base plate, for detecting the cleared road;

[0051] A grinding assembly, installed at the bottom of the base plate, for starting grinding and clearing the road marking after the camera detects that the road marking is not completely cleared;

[0052] The camera can check the road surface. When it is identified that the road surface markings are not completely removed, the grinding component is controlled to start. After the grinding component is started, the ground is immediately polished and cleaned, which is conducive to polishing and cleaning the ground that has been re-passed by high pressure, so as to completely remove the road markings without the need for multiple reciprocating high-pressure flushing. At the same time, the water flow during high-pressure flushing prevents the grinding component from raising dust during grinding, which is conducive to reducing the pollution caused by dust raised during grinding.

[0053] Preferably, the grinding assembly comprises:

[0054] An installation box, fixed to the top of the base plate and having a bottom that passes through the base plate;

[0055] A lifting platform is vertically slidably installed inside the installation box;

[0056] A cylinder is fixed inside the installation box and drives the lifting platform to move vertically through a telescopic rod;

[0057] Multiple grinding discs are rotatably mounted on the bottom of the lifting platform, and the tops of the rotating shafts of all the grinding discs pass through the lifting platform and are fixed with synchronous wheels, and all the synchronous wheels are connected by synchronous belt transmission;

[0058] A second motor is fixed to the top of the lifting platform and drives one of the synchronous wheels to rotate through an output shaft;

[0059] After the cylinder is started, the lifting platform is driven to move vertically through the telescopic rod. After the lifting platform moves vertically, it can drive the grinding disc to move downward. After the second motor is started, the synchronous wheel connected to it is driven to rotate through the output shaft. The synchronous wheels are connected by a synchronous belt drive and rotate synchronously, thereby driving the grinding disc to rotate through the synchronous wheel, so that the grinding disc keeps rotating when moving downward until the grinding disc moves to the ground to grind and remove the ground markings, which is beneficial to improve the removal efficiency of road markings.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

[0061] The present invention arranges a negative pressure recovery component and an interception component, so that after the road markings are cleared by a high-pressure water flow, the water flow used in clearing the road markings can be recovered, thereby helping to avoid the situation where the water flow accumulates on the road, causing the road to be slippery and thus causing a safety hazard. In addition, by recovering the water flow, it is helpful to avoid the waste of water flow, thereby helping to save water resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] like Figures 1 to 8 A road marking removal device shown includes a base 1, a plurality of universal wheels 101 are mounted on the bottom of the base 1, and further includes:

[0073] The bottom plate 102 is fixed to the bottom of the inner cavity including the base 1;

[0074] The barrel body 2 is fixed on the top of the base 1;

[0075] A high-pressure cleaning component is installed between the base 1 and the barrel 2 and is used for high-pressure cleaning of road markings;

[0076] The negative pressure recovery component is arranged in a frame shape, and the high pressure cleaning component is located inside the frame of the negative pressure recovery component, and is used to recover the water flow sprayed out by the high pressure cleaning component under high pressure;

[0077] The interception component is arranged in a frame shape, and the negative pressure recovery component is located inside the frame of the interception component, and is used to dynamically intercept the water flow generated by the high-pressure cleaning component when starting, so as to assist the high-pressure cleaning component in recovering the water flow;

[0078] In the prior art, high-pressure water jets are used to remove road markings. The high-speed water flow generated by the high-pressure water gun is used to wash away the marking materials. A large amount of water is required to remove road markings using the high-pressure water jet. When a large amount of water accumulates on the road, it may affect traffic, and the use of a large amount of water causes a waste of water resources.

[0079] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: when it is necessary to clear the road markings, the base 1 moves above the road markings through the universal wheels 101 at the bottom. At this time, the high-pressure cleaning component is started, and the high-pressure cleaning component sprays the water flow inside the barrel 2 at high pressure. The sprayed high-pressure water flow will clear the road markings. At the same time, the sprayed high-pressure water flow flows along the road surface. The set interception component can intercept the flowing water flow, so that the water flow can be kept inside the interception component in a dynamic state, which is conducive to avoiding the situation where the water flow flows along the road after flowing out and is difficult to gather for recovery. Subsequently, the negative pressure recovery component performs negative pressure recovery on the intercepted water flow, so that after the road markings are cleared by the high-pressure water flow, the water flow used for clearing the road markings can be recovered, which is conducive to avoiding the situation where the water flow accumulates on the road and causes the road to be slippery, thereby causing a safety hazard. In addition, by recycling the water flow, it is conducive to avoiding the waste of water flow, which is conducive to saving water resources.

[0084] After the first water pump 302 is started, the water flow inside the barrel body 2 is transported to the first connecting pipe 301, and the first connecting pipe 301 transports the water flow to the high-pressure spray gun 3. The high-pressure spray gun 3 sprays the water flow at high pressure, thereby clearing the road markings through the high-pressure sprayed water flow. The flat-arranged high-pressure spray gun 3 can make the sprayed high-pressure water flow present a flat shape, thereby increasing the cleaning range of the high-pressure water flow sprayed by the high-pressure spray gun 3, which is beneficial to improving the cleaning efficiency of the road markings.

By providing multiple second water pumps 403, it is helpful to increase the suction force of the negative pressure suction port 4 on the water flow, thereby helping to improve the recovery rate of the water flow;

[0092] The barrel body 2 is divided into a water tank 202 and a recovery tank 203 by a partition 201, so that the water flow that needs high-pressure cleaning is separated from the recovered sewage, which helps to prevent the recovered sewage from entering the interior of the water tank 202 and causing stone particles in the sewage to enter the interior of the water tank 202 and affect the use of the high-pressure spray gun 3.

When the second water pump 403 transports the recycled sewage to the inside of the recycling box 203, the water outlet end of the second water pump 403 is located below the filter plate 5, so that the recycled sewage is transported to the space below the filter plate 5 for accumulation. When the recycled sewage gradually accumulates and overflows the filter plate 5, the water flow can be filtered, so that all impurities contained in the recycled sewage are stored in the position below the filter plate 5, and the position above the filter plate 5 is the filtered water flow. After the third water pump 6 is started, the filtered water flow above the filter plate 5 enters the interior of the water tank 202 along the path of the water inlet pipe 601, the water inlet pipe 601 and the water outlet pipe 602, so that the recycled sewage can be reused, which is beneficial to prolong the high-pressure flushing and cleaning time of the road marking by the device each time, and is beneficial to reduce the waste of water flow.

The rotation direction of the roller brush 8 is toward the negative pressure recovery component, so that the rotating roller brush 8 can play a role of brushing and sweeping the water flowing on the ground, pushing the water flow to accumulate in the direction of the negative pressure recovery component, which is conducive to the water flow being recovered by the negative pressure recovery component;

[0108] The arc plate 801 and the protection box 805 can protect the roller brush 8 and the first bevel gear 802, so that when the roller brush 8 brushes the water, it will not drive the water flow into the space above the bottom plate 102 to cause damage to the internal parts.

After the grinding component is started, the ground is immediately polished and cleaned, which is conducive to polishing and cleaning the ground that has been re-passed by high pressure, so as to completely remove the road markings without the need for multiple reciprocating high-pressure flushing. At the same time, the water flow during high-pressure flushing prevents the grinding component from raising dust during grinding, which is conducive to reducing the pollution caused by dust raised during grinding.

All the synchronous wheels 904 are connected by synchronous belts 905.

[0126] The second motor 906 is fixed to the top of the lifting platform 901 and drives one of the synchronous wheels 904 to rotate through the output shaft;

[0127] After the cylinder 903 is started, it drives the lifting platform 901 to move vertically through the telescopic rod.

After the second motor 906 is started, it drives the synchronous wheel 904 connected thereto to rotate through the output shaft. The synchronous wheels 904 are connected to each other through the transmission connection of the synchronous belt 905 and rotate synchronously, thereby driving the grinding disc 9 to rotate through the synchronous wheel 904, so that the grinding disc 9 keeps rotating when moving downward until the grinding disc 9 moves to the ground to grind and remove the ground markings, which is beneficial to improve the removal efficiency of road markings.

[0128] The working principle of the present invention is as follows: when it is necessary to clear the road markings, the base 1 moves above the road markings through the universal wheels 101 at the bottom, and the high-pressure clearing component is started at this time. The high-pressure clearing component sprays the water flow inside the barrel 2 at high pressure, and the sprayed high-pressure water flow will clear the road markings. At the same time, the sprayed high-pressure water flow flows along the road surface. The arranged intercepting component can intercept the flowing water flow, so that the water flow can be kept inside the intercepting component in a dynamic state, thereby helping to avoid the situation where the water flow flows along the road after flowing out and is difficult to gather for recovery. Subsequently, the negative pressure recovery component performs negative pressure recovery on the intercepted water flow, so that after the road markings are cleared by the high-pressure water flow, the water flow used for clearing the road markings can be recovered, thereby helping to avoid the situation where the water flow accumulates on the road and causes the road to be slippery, thereby causing a safety hazard. Moreover, by recovering the water flow, it can help to avoid the waste of water flow, thereby helping to save water resources.
