Description

Technical Field

[0001] This invention relates to the field of asphalt overlay construction equipment technology, specifically a base surface cleaning device and method for asphalt overlay construction. Background Technology

[0002] In asphalt overlay construction, the base surface cleaning device refers to the original cement pavement of the road, which is called the base surface. Covering the original cement pavement base surface with a layer of asphalt is called asphalt overlay. In asphalt overlay construction, the base surface needs to be cleaned by a dust removal machine. It mainly consists of a dust removal machine body and a rotating dust removal brush at the bottom of the machine body. It is widely used in the road industry.

[0003] A search revealed Chinese patent CN116397580A, which discloses an invention belonging to the technical field of asphalt overlay construction equipment. The invention discloses a base surface cleaning device for asphalt overlay construction, comprising a base with a housing fixedly connected to one side. The invention utilizes an atomizing nozzle, a sponge, an L-shaped toothed plate, an arc-shaped brush plate, an inclined tube, an arc-shaped clamp, and a filter plate. During asphalt overlay construction, the motor is first started, driving the output shaft to rotate the pulley and simultaneously the rotating shaft. The rotating shaft, in turn, rotates the sponge. Then, a water pump is activated, drawing water from the tank through a water pipe to the atomizing nozzle. The water is then sprayed onto the rotating sponge surface, moistening it. Finally, the worker pushes the handle, moving the base and wheels to the roadbed surface, adsorbing dust onto the sponge surface. This effectively reduces the amount of dust stirred up by the brush during cleaning, preventing inhalation by workers and pedestrians.

[0004] Existing cleaning devices spray water onto a sponge via atomizing nozzles, and then the sponge absorbs dust by contacting the road surface. While a wet sponge enhances dust absorption, in actual use, the rotating sponge stirs up dust when it touches the ground. This dust can be inhaled, causing irreversible lung damage to workers. Furthermore, the devices lack necessary cleaning mechanisms. Therefore, this invention designs a base surface cleaning device for asphalt overlay construction to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a surface cleaning device and method for asphalt overlay construction. Through the cooperation of a vacuum cleaner and a cleaning sponge, a certain amount of dust and dusty smoke is generated during the rotation of the cleaning sponge. At this time, the vacuum cleaner located at the bottom of the third gear is activated to absorb the dust. The working principle of the vacuum cleaner is similar to that of existing vacuuming structures; it can generate negative pressure inside the structure to absorb dust and dust, avoiding harm to the health of workers from the stirred-up dust and dust, thus solving the aforementioned problem of lacking a dust suppression structure.

[0006] To achieve the above objectives, according to a first aspect of the present invention, a base surface cleaning device for asphalt overlay construction is provided, comprising a moving mechanism, a dust suppression mechanism, a cleaning mechanism, and a water spraying mechanism.

[0007] The moving mechanism includes a vehicle body, a fixed base is fixedly connected to the bottom of the vehicle body, a first rotating shaft is rotatably connected between the fixed bases, and a roller is rotatably connected to the outer ring of the first rotating shaft;

[0008] Dust suppression mechanism: The dust suppression mechanism includes a support frame, a second rotating shaft is rotatably connected to the inner cavity of the support frame, a second gear is fixedly connected to the bottom of the second rotating shaft, a third rotating shaft is rotatably connected to the top of the inner cavity of the support frame, a third gear is fixedly connected to the bottom of the third rotating shaft, the second gear and the third gear mesh with each other, and a vacuum cleaner is fixedly connected to the bottom of the third gear. The vacuum cleaner is arranged in multiple circumferential arrays.

[0009] Cleaning mechanism: The cleaning mechanism includes a cleaning sponge, which is distributed in multiple linear arrays;

[0010] Water spraying mechanism: The water spraying mechanism includes a water tank, a nozzle is provided in the inner cavity of the support frame, and a water pipe is provided between the water tank and the nozzle.

[0011] As can be seen from the above technical solutions, the working principle of the vacuum cleaner is similar to that of existing vacuuming structures. It can generate negative pressure inside the structure to absorb dust and particulate matter.

[0012] Preferably, the top of the vehicle body is provided with a threaded hole, and a threaded rod is threadedly connected to the inner cavity of the threaded hole. The bottom of the vehicle body is provided with a groove, and a fixing block is slidably connected to the inner cavity of the groove. A base plate is fixedly connected to the bottom of the fixing block. The fixing block and the threaded rod are rotatably connected. A crank is fixedly connected to the top of the threaded rod, and the threaded rod will rotate as the crank rotates.

[0013] As can be seen from the above technical solution, when the device needs to clean the road surface at a certain location for a long time, the crank handle is turned to drive the threaded rod to rotate in the threaded hole, thereby driving the fixed block connected to the bearing to move, so that the bottom plate of the fixed block contacts the ground, thus fixing the position of the device.

[0014] Preferably, a sliding groove is provided in the inner cavity of the groove, and a slider is slidably connected in the inner cavity of the sliding groove. The slider is fixedly connected to the fixed block. The sliding groove is convex in shape, which can make the slider move more stably.

[0015] As can be seen from the above technical solution, a slider is fixedly connected to the outer wall of the fixed block. The slider can slide within the inner cavity of the groove, thereby restricting the movement direction of the fixed block and making its movement more stable.

[0016] Preferably, the threaded holes are provided in two sets and are symmetrically distributed around the vehicle body, the threaded rods are provided in two sets and are symmetrically distributed around the vehicle body, the grooves are provided in two sets and are symmetrically distributed around the vehicle body, the fixing blocks are provided in two sets and are symmetrically distributed around the vehicle body, and the base plate is provided in two sets and is symmetrically distributed around the vehicle body.

[0017] Preferably, a storage box is fixedly connected to the inner cavity of the vehicle body, a cover plate is hinged to the front of the vehicle body, and a first handle is fixedly connected to the back of the cover plate. The cover plate moves with the movement of the first handle plate.

[0018] Preferably, a dual-axis motor is fixedly connected to the top of the support frame, a fourth rotating shaft is fixedly connected to the left side of the dual-axis motor, a first bevel gear is fixedly connected to the outer ring of the fourth rotating shaft, and a second bevel gear is fixedly connected to the outer ring of the second rotating shaft. The first bevel gear and the second bevel gear mesh with each other, and starting the dual-axis motor can drive the second rotating shaft to rotate.

[0019] Preferably, a fifth rotating shaft is fixedly connected to the right side of the dual-axis motor, a first rotating seat is fixedly connected to one side of the fifth rotating shaft, a support plate is fixedly connected to the bottom of the support frame, a rotating rod is rotatably connected to the inner cavity of the support plate, a second rotating seat is fixedly connected to the right side of the rotating rod, and the first rotating seat and the second rotating seat are connected by a belt.

[0020] As described in the above technical solution, starting the dual-axis motor causes the fifth rotating shaft to rotate, which in turn drives the first rotating seat to rotate. The first and second rotating seats are connected by a belt, so the second rotating seat also rotates, thus rotating the rotating rod. The rotation of the rotating rod causes the moistened cleaning sponge to rotate, effectively adsorbing dust from the roadbed surface. Simultaneously, the rotation of the rollers at the bottom of the vehicle allows the device to be moved, enabling cleaning over a larger area.

[0021] Preferably, the cleaning sponge is fitted around the outer ring of the rotating rod, and the lowest point of the cleaning sponge is at the same height as the lowest point of the roller.

[0022] Preferably, a mounting base is fixedly connected to the inner cavity of the support frame, a second motor is fixedly connected to the inner cavity of the mounting base, a connecting plate is fixedly connected to the inner cavity of the support frame, a lead screw is fixedly connected to one side of the output shaft of the second motor, a moving block is threaded to the outer ring of the lead screw, the moving block is fixedly connected to the nozzle, and starting the second motor can move the moving block.

[0023] As can be seen from the above technical solution, starting the second motor drives the lead screw to rotate, which in turn moves the moving block connected to the outer ring threaded connection in the left and right directions, thereby changing the position of the nozzle, wetting the cleaning sponge at different locations, and improving the dust adsorption effect.

[0024] Preferably, a limiting rod is fixedly connected between the mounting base and the connecting plate, and the movable block is fitted onto the outer ring of the limiting rod and can move in the left and right directions. The limiting rod enables the movable block to move more stably.

[0025] According to a second aspect of the present invention, a method for cleaning a substrate during asphalt overlay construction is provided, comprising the following steps:

[0026] S100: Movement and fixation. The device can be moved by the rotation of the rollers at the bottom of the device, while the device can be fixed by the groove and the fixing block in the inner cavity to prevent shaking during subsequent operation.

[0027] S200: Water spray cleaning. The water pump can pump clean water from the water tank into the nozzle through the water pipe. The nozzle sprays out fine water droplets. In conjunction with the rotation of the second motor and the lead screw, the position of the nozzle is changed.

[0028] S300: Sponge cleaning, the rotation of the dual-axis motor drives the rotation of the fifth rotating shaft, which, together with the belt connection between the first and second rotating seats, realizes the rotation of the rotating rod, thereby driving the rotation of the moist cleaning sponge to achieve the adsorption of dust on the roadbed surface;

[0029] S400: Vacuuming. The vacuum cleaner generates negative pressure inside its structure to absorb dust and particulate matter. During the rotation of the dual-axis motor and the fourth rotating shaft, the first bevel gear rotates. Because the first and second bevel gears mesh with each other, the second and third gears also rotate, increasing the area from which dust can be absorbed.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. In this invention, the vacuum cleaner and cleaning sponge work together. During the rotation of the cleaning sponge, a certain amount of dust and dusty smoke is generated. At this time, the vacuum cleaner located at the bottom of the third gear will start to absorb the dust. The working principle of the vacuum cleaner is similar to that of existing vacuuming structures. It can generate negative pressure inside the structure to absorb dust and dust, avoiding harm to the health of workers caused by the raised dust and dust.

[0032] 2. In this invention, through the cooperation of a dual-axis motor and a second rotating shaft, when the dual-axis motor rotates, a fourth rotating shaft located on one side of the motor also rotates. During the rotation of the fourth rotating shaft, the first bevel gear rotates. Since the first and second bevel gears mesh with each other, the second bevel gear also rotates, causing the second rotating shaft to rotate. This causes the second gear at the bottom of the second rotating shaft to rotate, which in turn drives the third gear, which meshes with the second gear, to rotate around the third rotating shaft. The rotation of the third gear allows for a change in the position of the vacuum cleaner, increasing the dust absorption range. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1;

[0047] Please see Figure 1 - Figure 10 In this embodiment of the invention, a base surface cleaning device for asphalt overlay construction includes a moving mechanism 1, a dust suppression mechanism 2, a cleaning mechanism 3, and a water spraying mechanism 4, wherein:

[0048] Mobile mechanism 1: The mobile mechanism 1 includes a vehicle body 101, a fixed seat 102 is fixedly connected to the bottom of the vehicle body 101, a first rotating shaft 103 is rotatably connected between the fixed seats 102, and a roller 104 is rotatably connected to the outer ring of the first rotating shaft 103.

The vacuum cleaner 206 is arranged in multiple circumferential arrays.

[0050] Cleaning mechanism 3: Cleaning mechanism 3 includes cleaning sponge 301, which is distributed in multiple linear arrays;

[0051] Spraying mechanism 4: The spraying mechanism 4 includes a water tank 401, a nozzle 402 is provided in the inner cavity of the support frame 201, and a water pipe is provided between the water tank 401 and the nozzle 402.

[0052] like Figure 3 As shown, a threaded hole 105 is provided on the top of the vehicle body 101, and a threaded rod 106 is threadedly connected in the inner cavity of the threaded hole 105. A groove 107 is provided on the bottom of the vehicle body 101, and a fixing block 108 is slidably connected in the inner cavity of the groove 107. A base plate 109 is fixedly connected to the bottom of the fixing block 108. The fixing block 108 and the threaded rod 106 are rotatably connected. A crank handle 110 is fixedly connected to the top of the threaded rod 106.

[0053] like Figure 4 As shown, a sliding groove 111 is provided in the inner cavity of the groove 107, and a slider 112 is slidably connected in the inner cavity of the sliding groove 111. The slider 112 is fixedly connected to the fixing block 108.

[0054] like Figure 3 As shown, there are two sets of threaded holes 105 symmetrically distributed around the vehicle body 101, two sets of threaded rods 106 symmetrically distributed around the vehicle body 101, two sets of grooves 107 symmetrically distributed around the vehicle body 101, two sets of fixing blocks 108 symmetrically distributed around the vehicle body 101, and two sets of base plates 109 symmetrically distributed around the vehicle body 101.

[0056] When the device is needed to clean a specific location of the road surface for an extended period, turning the crank handle 110 causes the threaded rod 106 to rotate within the threaded hole 105. This, in turn, moves the bearing-connected fixing block 108, causing the base plate 109 at the bottom of the fixing block 108 to contact the ground, thus fixing the device in place. A slider 112 is fixedly connected to the outer wall of the fixing block 108. The slider 112 can slide within the inner cavity of the groove 111, thereby restricting the direction of movement of the fixing block 108 and making its movement more stable.

[0057] By combining a vacuum cleaner and a cleaning sponge, the rotating sponge generates a certain amount of dust and fumes. At this point, the vacuum cleaner, located at the bottom of the third gear, activates to absorb the dust. The working principle of this vacuum cleaner is similar to that of existing vacuum systems; it creates negative pressure inside the structure to absorb dust and fumes, preventing the generated dust and fumes from harming the health of workers.

[0058] Example 2;

[0059] Please see Figure 1 - Figure 10 In this embodiment of the invention, a dual-axis motor 207 is fixedly connected to the top of the support frame 201, a fourth rotating shaft 208 is fixedly connected to the left side of the dual-axis motor 207, a first bevel gear 209 is fixedly connected to the outer ring of the fourth rotating shaft 208, a second bevel gear 210 is fixedly connected to the outer ring of the second rotating shaft 202, the first bevel gear 209 and the second bevel gear 210 mesh with each other, a fifth rotating shaft 212 is fixedly connected to the right side of the dual-axis motor 207, a first rotating seat 213 is fixedly connected to one side of the fifth rotating shaft 212, a support plate 214 is fixedly connected to the bottom of the support frame 201, a rotating rod 302 is rotatably connected to the inner cavity of the support plate 214, a second rotating seat 216 is fixedly connected to the right side of the rotating rod 302, the first rotating seat 213 and the second rotating seat 216 are connected by a belt, a cleaning sponge 301 is fitted on the outer ring of the rotating rod 302, and the lowest point of the cleaning sponge 301 is at the same height as the lowest point of the roller 104.

[0060] The dual-axis motor 207 is activated, and its rotation drives the fifth rotating shaft 212, which in turn drives the first rotating seat 213. The first rotating seat 213 and the second rotating seat 216 are connected by a belt, so the second rotating seat 216 also rotates, causing the rotating rod 302 to rotate. The rotation of the rotating rod 302 drives the moistened cleaning sponge 301 to rotate, adsorbing dust from the roadbed surface. Simultaneously, the rotation of the rollers 104 at the bottom of the vehicle body 101 allows the device to move, enabling cleaning over a larger area. During the rotation of the cleaning sponge 301, a certain amount of dust and dust fumes are generated. At this time, the vacuum cleaner 206 located at the bottom of the third gear 205 is activated to absorb the dust. The working principle of the vacuum cleaner 206 is similar to that of existing vacuuming structures; it generates negative pressure inside the structure to absorb dust and dust. As the dual-axis motor 207 rotates, the fourth shaft 208 located on one side of the motor 207 also rotates. This rotation of the fourth shaft 208 drives the first bevel gear 209 to rotate. Since the first bevel gear 209 meshes with the second bevel gear 210, the second bevel gear 210 also rotates, causing the second shaft 202 to rotate. This, in turn, causes the second gear 203 at the bottom of the second shaft 202 to rotate, which in turn drives the third gear 205, which meshes with the second gear 203, to rotate around the third shaft 204. The rotation of the third gear 205 changes the position of the vacuum cleaner 206, increasing the dust absorption range.

[0061] Example 3;

[0062] Please see Figure 1 - Figure 10 In this embodiment of the invention, a mounting base 217 is fixedly connected to the inner cavity of the support frame 201, a second motor 218 is fixedly connected to the inner cavity of the mounting base 217, a connecting plate 219 is fixedly connected to the inner cavity of the support frame 201, a lead screw 220 is fixedly connected to one side of the output shaft of the second motor 218, a moving block 211 is threadedly connected to the outer ring of the lead screw 220, the moving block 211 is fixedly connected to the nozzle 402, a limiting rod 215 is fixedly connected between the mounting base 217 and the connecting plate 219, and the moving block 211 is fitted onto the outer ring of the limiting rod 215 and can move in the left and right directions.

[0063] The second motor 218 is started, which drives the lead screw 220 to rotate, thereby moving the moving block 211 connected by the outer ring thread in the left and right directions, thereby changing the position of the nozzle 402, wetting the cleaning sponge 301 at different positions, and improving the dust adsorption effect.

[0064] Please see Figure 11 This invention provides a method for cleaning the substrate during asphalt overlay construction, comprising the following steps:

[0065] S100: Movement and fixation. With the rotation of the roller 104 at the bottom of the device, the device can be moved. With the groove 107 and the fixing block 108 in the inner cavity, the device can be fixed to prevent shaking during subsequent operation.

[0066] S200: Water spray cleaning. The water pump can pump clean water from the water tank 401 into the nozzle 402 through the water pipe. The nozzle 402 sprays out fine water droplets. With the rotation of the second motor 218 and the lead screw 220, the position of the nozzle 402 is changed.

[0067] S300: Sponge cleaning, the rotation of the dual-axis motor 207 drives the rotation of the fifth rotating shaft 212, which, together with the belt connection between the first rotating seat 213 and the second rotating seat 216, realizes the rotation of the rotating rod 302, thereby driving the rotation of the wet cleaning sponge 301 to achieve the adsorption of dust on the roadbed surface;

[0068] S400: Vacuuming. The vacuum cleaner 206 can generate negative pressure inside its structure to absorb dust and particulate matter. During the rotation of the dual-axis motor 207 and the fourth rotating shaft 208, the first bevel gear 209 will rotate. Since the first bevel gear 209 meshes with the second bevel gear 210, the second gear 203 and the third gear 205 will also rotate, thereby increasing the dust absorption range.

[0069] When using this asphalt overlay surface cleaning device, first start the nozzle 402. The water tank 401 contains a water pump that pumps clean water from the tank into the nozzle 402 through a water pipe. The nozzle 402 sprays out fine water droplets that fall onto the cleaning sponge 301. Then, start the dual-shaft motor 207. The rotation of the dual-shaft motor 207 drives the fifth rotating shaft 212, which in turn drives the first rotating seat 213. The first rotating seat 213 and the second rotating seat 216 are connected by a belt, so the second rotating seat 216 also rotates, causing the rotating rod 302 to rotate. The rotation of the rotating rod 302 drives the moistened cleaning sponge 301 to rotate, effectively adsorbing dust from the roadbed surface. Simultaneously, the rotation of the rollers 104 at the bottom of the vehicle body 101 allows the device to move, enabling cleaning over a larger area. The second motor 218 is activated, driving the lead screw 220 to rotate. This causes the moving block 211, connected by an outer thread, to move left and right, changing the position of the nozzle 402 and wetting the cleaning sponge 301 at different locations, thus improving dust adsorption. During the rotation of the cleaning sponge 301, a certain amount of dust and dust fumes are generated. At this time, the vacuum cleaner 206, located at the bottom of the third gear 205, is activated to absorb the dust. The working principle of the vacuum cleaner 206 is similar to that of existing vacuuming structures; it generates negative pressure inside the structure to absorb dust and dust. As the dual-axis motor 207 rotates, the fourth rotating shaft 208, located on one side of the dual-axis motor 207, also rotates. The rotation of the fourth rotating shaft 208 drives the first bevel gear 209 to rotate. Since the first bevel gear 209 and the second bevel gear 210 mesh with each other, the second bevel gear 210 will also rotate, thereby rotating the second shaft 202. This causes the second gear 203 at the bottom of the second shaft 202 to rotate, which in turn drives the third gear 205, which meshes with the second gear 203, to rotate around the third shaft 204. The rotation of the third gear 205 can change the position of the vacuum cleaner 206, thereby increasing the dust absorption range. The storage box 113 can hold some cleaning tools for easy use. When the device needs to clean a certain area of ​​the road for a long time, the crank handle 110 is turned, causing the threaded rod 106 to rotate in the threaded hole 105, thereby moving the fixed block 108 connected to the bearing, so that the bottom plate 109 of the fixed block 108 contacts the ground, thus fixing the position of the device. A slider 112 is fixedly connected to the outer wall of the fixed block 108. The slider 112 can slide in the inner cavity of the slide groove 111, thereby restricting the movement direction of the fixed block 108 and making the movement of the fixed block 108 more stable.

[0070] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
