Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a marking line removing device for highway maintenance. Background Art

[0002] With the rapid development of my country's economy, the traffic volume on the road is becoming larger and larger. Therefore, the highway markings are being worn out faster and faster. In order to restore the function of highway markings in controlling and guiding traffic, it is necessary to redraw the highway markings. However, before redrawing the highway markings, the original highway markings need to be cleared.

[0003] After searching, the Chinese patent application number CN201810428207.7 discloses a highway marking clearing device, including a base plate, a clearing mechanism and a cleaning mechanism. The base plate is a rectangular structure and a plurality of rectangularly distributed baffles are provided at the lower end of the base plate. However, the above technical solution does not have a corresponding device to allow the cleaning device to be close to the road surface. When the cleaning device moves to a relatively uneven road surface, the cleaning device cannot adaptively adjust itself to be close to the ground, resulting in the problem that the marking clearing device cannot completely clear the markings on the uneven road surface.

[0008] Further: the transmission mechanism includes a motor and a second transmission gear, the motor is fixed on an outer wall of one side of the guide plate, the second transmission gear is connected to the output shaft of the motor through a coupling, and the second transmission gear is connected to the second rotating shaft through a transmission chain.

[0009] Further preferred: the scraper mechanism includes a sliding frame, a scraper and a second brush plate, the sliding frame is slidably connected to the bottom outer wall of the mounting plate, the scraper is fixed to the bottom outer wall of the sliding frame, the second brush plate is fixed to the bottom outer wall of the scraper, and one side of the sliding frame is fixed to one side outer wall of the elastic arc plate.

[0010] As a preferred embodiment of the present invention: the spray mechanism includes a liquid storage tank, a liquid pump, a mounting groove and a liquid spray plate, the liquid storage tank is fixed on the top outer wall of the mounting plate, the liquid pump is fixed on the top outer wall of the mounting plate, the liquid storage tank and the liquid pump are connected by a pipeline, the mounting groove is arranged on the outer wall of the mounting plate, the liquid spray plate is fixed on the inner wall of the mounting groove, and the liquid spray plate is connected to the liquid pump through a pipeline.

[0011] As a further preferred embodiment of the present invention: an L-shaped plate is fixed to the bottom outer wall of the mounting plate, a group of second elastic telescopic rods is fixed to one side outer wall of the L-shaped plate, and the telescopic ends of the second elastic telescopic rods are fixed to one side outer wall of the sliding frame.

[0012] As a further solution of the present invention: a plurality of buffer blocks are fixed to the outer wall at the bottom of the mounting plate.

[0013] On the basis of the above scheme: a push handle is fixed on the outer wall of the second support frame, a liquid filling port is arranged on the outer wall of the liquid storage box, limiting blocks are fixed on the outer walls on both sides of the guide plate, and a traction buckle is fixed on the outer wall on one side of the first support frame.

[0014] Based on the above scheme, it is preferred that: the inner wall of the first support frame is slidably connected with a movable frame, the movable frame is fixed on the outer wall of one side of the support plate, the inner wall of the movable frame is rotatably connected with a first rotating shaft, the outer wall of the first rotating shaft is fixed with a first transmission gear, the outer wall of the first rotating shaft is fixed with a group of first brush plates, and the first transmission gear is connected to the second rotating shaft through a transmission chain.

[0015] The beneficial effects of the present invention are:

[0016] 1. The elastic arc plate connected at the bottom of the mounting plate can squeeze the limiting groove of the outer wall of the supporting plate through its own elastic force, thereby squeezing the supporting plate downward through the elastic force provided by the elastic arc plate, so that the cleaning brush disc can rotate closely to the road surface when rotating. When the road surface is uneven, the mounting gear ring as a whole will move up and down under the squeezing of the road surface, thereby squeezing the elastic arc plate through the supporting plate. At this time, the elastic arc plate will buffer the pressure on the supporting plate through its own elastic force, and at the same time, the cleaning brush disc at the bottom of the mounting gear ring will always rotate closely to the road surface under the elastic force of the elastic arc plate, thereby completely removing the markings on the uneven road surface, thereby improving the cleaning effect of the marking removal equipment on uneven roads.

[0017] 2. The guide frame and the guide plate can guide the support plate when it moves up and down, thereby improving the stability of the support plate when it follows the ups and downs of the road surface. At the same time, the first support frame and the second support frame support the mounting plate as a whole through a plurality of first elastic telescopic rods. The elastic force provided by the first elastic telescopic rods can allow the cleaning, spraying and scraping mechanisms at the bottom of the mounting plate to be close to the road surface, thereby improving the cleaning effect of the cleaning device on the road surface.

[0018] 3. When the mounting gear ring squeezes the elastic arc plate through the support plate under the pressure of the road surface, the elastic arc plate will be squeezed and contracted, and will push the sliding frame as a whole to slide back and forth on the outer wall of the mounting plate through one end, thereby driving the scraper and the second brush plate as a whole to scrape back and forth on the road surface, and scrape off the road marking residues after being swept by the cleaning brush disc from the road surface, thereby improving the cleaning effect of the cleaning device on the road markings and facilitating the staff to recycle the cleaned road marking residues.

[0019] 4. The second elastic telescopic rod can support and limit the entire sliding frame when it moves forward and backward through its own elastic force. When the mounting gear ring moves to a recessed place on the road surface, the mounting gear ring will no longer squeeze the elastic arc plate. At this time, the elastic arc plate will reopen through its own elastic force, thereby squeezing the mounting gear ring to move downward as a whole, so that the mounting gear ring can be close to the recessed road surface. At the same time, the sliding frame will also move back under the elastic force of the second elastic telescopic rod, squeezing one end of the elastic arc plate, so that the elastic arc plate as a whole can more stably push the support plate and the mounting gear ring to move downward as a whole to fit the road surface.

[0020] 5. When the motor drives multiple installed gear rings to rotate, the first transmission gear on one side of the movable frame will be driven to rotate through the second rotating shaft on the outer wall of the installed gear ring, thereby driving a group of first brush plates on the outer wall of the first rotating shaft to rotate, sweeping away stones and other debris on the road surface, so that the cleaning liquid sprayed by the subsequent spraying mechanism can fall on the clean road surface, avoiding the debris remaining on the road surface affecting the subsequent cleaning brush plate to clean the road markings.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Embodiment 1:

[0031] A road marking removal device for highway maintenance, such as Figure 1-6As shown, it includes a mounting plate 1, guide frames 9 are fixed to the outer walls of both sides of the mounting plate 1 respectively, and a guide plate 12 is slidably connected to the inner wall of the guide frame 9, a support plate 27 is fixed to the outer wall of the guide plate 12, and a plurality of second rotating shafts 34 are rotatably connected to the inner wall of the support plate 27, and a mounting gear ring 20 is fixed to the outer wall of the second rotating shaft 34, and two adjacent mounting gear rings 20 are meshed and connected, and a cleaning brush disc 21 is fixed to the outer wall of the bottom of the mounting gear ring 20, and a group of limiting grooves 35 are opened on the outer wall of the support plate 27, and a fixed end 31 is fixed to the outer wall of the bottom of the mounting plate 1, and an elastic arc plate 30 is fixed to the outer wall of one side of the fixed end 31, and the outer wall of the elastic arc plate 30 is slidably connected to the inner wall of the limiting groove 35, and one end of the elastic arc plate 30 is slidably connected to the bottom outer wall of the mounting plate 1, and a transmission mechanism is provided on the outer wall of the guide plate 12 and the support plate 27, and a spray mechanism is provided on the outer wall of the mounting plate 1, and a scraper mechanism is slidably connected to the outer wall of the bottom of the mounting plate 1;

[0032] The first support frame 7 and the second support frame 16 are slidably connected at both ends of the mounting plate 1, and a plurality of first elastic telescopic rods 26 are fixed to the outer walls of one side of the first support frame 7 and the second support frame 16 respectively, and a group of fixing rods 8 are fixed to the outer walls of one side of the first support frame 7 and the second support frame 16, and the telescopic ends of the first elastic telescopic rods 26 are fixed to the top outer wall of the mounting plate 1, and the pulleys 2 are fixed to the bottom outer walls of the first support frame 7 and the second support frame 16 respectively.

[0033] The staff moves the marking cleaning device to the corresponding road surface through the pulley 2, and then starts the transmission mechanism to drive the second rotating shaft 34 to rotate. When the second rotating shaft 34 rotates, it will drive the mounting gear ring 20 of the outer wall to rotate. When the mounting gear ring 20 rotates, it will drive multiple mounting gear rings 20 meshing and connected to the outer wall to rotate at the same time, thereby driving multiple cleaning brush discs 21 at the bottom of the mounting gear ring 20 to rotate at the same time. The elastic arc plate 30 connected to the bottom of the mounting plate 1 can squeeze the limiting groove 35 on the outer wall of the support plate 27 through its own elastic force, so that the support plate 27 is pushed downward by the elastic force provided by the elastic arc plate 30. The cleaning brush disc 21 can rotate closely against the road surface when it rotates. When the road surface is uneven, the mounting gear ring 20 as a whole will move up and down under the pressure of the road surface, thereby squeezing the elastic arc plate 30 through the support plate 27. At this time, the elastic arc plate 30 will buffer the pressure on the support plate 27 through its own elastic force, and at the same time, the cleaning brush disc 21 at the bottom of the mounting gear ring 20 will always rotate closely against the road surface under the elastic force of the elastic arc plate 30, thereby completely removing the markings on the uneven road surface, thereby improving the cleaning effect of the marking removal equipment on the uneven road surface.

[0034] The guide frame 9 and the guide plate 12 can guide the support plate 27 when it moves up and down, thereby improving the stability of the support plate 27 when it follows the ups and downs of the road surface. At the same time, the first support frame 7 and the second support frame 16 support the mounting plate 1 as a whole through multiple first elastic telescopic rods 26. The elastic force provided by the first elastic telescopic rods 26 can make the cleaning, spraying and scraping mechanisms at the bottom of the mounting plate 1 close to the road surface, thereby improving the cleaning effect of the cleaning device on the road surface.

[0035] like Figure 2 and Figure 4-6 As shown, the transmission mechanism includes a motor 24 and a second transmission gear 25. The motor 24 is fixed on the outer wall of one side of the guide plate 12. The second transmission gear 25 is connected to the output shaft of the motor 24 through a coupling. The second transmission gear 25 is connected to the second rotating shaft 34 through a transmission chain. The motor 24 drives the second transmission gear 25 to rotate. When the second transmission gear 25 rotates, it will drive the second rotating shaft 34 to rotate through the transmission chain of the outer wall, thereby driving the mounting gear ring 20 at the bottom of the second rotating shaft 34 to rotate, thereby driving the multiple cleaning brush discs 21 at the bottom of the support plate 27 to rotate, and cleaning the bottom road surface.

[0036] like Figure 4-6 As shown, the scraper mechanism includes a sliding frame 17, a scraper 18 and a second brush plate 19. The sliding frame 17 is slidably connected to the bottom outer wall of the mounting plate 1, the scraper 18 is fixed to the bottom outer wall of the sliding frame 17, the second brush plate 19 is fixed to the bottom outer wall of the scraper 18, and one side of the sliding frame 17 is fixed to one side outer wall of the elastic arc plate 30; when the mounting gear ring 20 squeezes the elastic arc plate 30 through the support plate 27 under the pressure of the road surface, the elastic arc plate 30 will push the sliding frame 17 as a whole to slide back and forth on the outer wall of the mounting plate 1 through one end after being squeezed and contracted, thereby driving the scraper 18 and the second brush plate 19 to scrape the road surface as a whole, and scrape off the road surface marking residues after being cleaned by the cleaning brush disc 21 from the road surface, thereby improving the cleaning effect of the cleaning device on the road surface markings and facilitating the staff to recycle the cleaned road surface marking residues.

[0037] like Figure 1-2 and Figure 5As shown, the spray mechanism includes a liquid storage tank 13, a liquid extraction pump 10, a mounting groove 32 and a liquid spray plate 23. The liquid storage tank 13 is fixed on the top outer wall of the mounting plate 1, and the liquid extraction pump 10 is fixed on the top outer wall of the mounting plate 1. The liquid storage tank 13 and the liquid extraction pump 10 are connected by a pipeline. The mounting groove 32 is arranged on the outer wall of the mounting plate 1, and the liquid spray plate 23 is fixed on the inner wall of the mounting groove 32. The liquid spray plate 23 is connected to the liquid extraction pump 10 through a pipeline; after the staff turns on the liquid extraction pump 10, the liquid extraction pump 10 will extract the cleaning liquid inside the liquid storage tank 13 and transport it to the liquid spray plate 23 through a pipeline when it is running. Subsequently, the road surface sprayed by the liquid spray plate 23, as the marking line clearing device continues to move forward, the subsequent rotating cleaning brush plate 21 will clean the road surface sprayed with the cleaning liquid, thereby better removing the marking lines on the road surface.

[0038] like Figure 4 As shown, an L-shaped plate 28 is fixed to the outer wall at the bottom of the mounting plate 1, and a group of second elastic telescopic rods 29 are fixed to the outer wall on one side of the L-shaped plate 28, and the telescopic end of the second elastic telescopic rod 29 is fixed to the outer wall on one side of the sliding frame 17; the second elastic telescopic rod 29 can support and limit the sliding frame 17 as a whole when it moves forward and backward through its own elastic force. When the mounting gear ring 20 moves as a whole to the recessed part of the road surface, the mounting gear ring 20 will no longer squeeze the elastic arc plate 30. At this time, the elastic arc plate 30 will reopen through its own elastic force, thereby squeezing the mounting gear ring 20 to move downward as a whole, so that the mounting gear ring 20 can be close to the recessed road surface. At the same time, the sliding frame 17 will also move back under the elastic force of the second elastic telescopic rod 29, squeezing one end of the elastic arc plate 30, so that the elastic arc plate 30 as a whole can more stably push the support plate 27 and the mounting gear ring 20 as a whole to move downward to fit the road surface.

[0039] like Figure 5 As shown, a plurality of buffer blocks 33 are fixed to the outer wall at the bottom of the mounting plate 1; the buffer blocks 33 can limit and buffer the support plate 27 when it moves upward.

[0040] like Figure 1 As shown, a push handle 15 is fixed to the outer wall of the second support frame 16, a liquid filling port 14 is provided on the outer wall of the liquid storage tank 13, limit blocks 11 are respectively fixed to the outer walls on both sides of the guide plate 12, and a traction buckle 6 is fixed to the outer wall on one side of the first support frame 7; the staff can tow the marking cleaning device through the traction buckle 6 through the corresponding traction vehicle, and at the same time, the pushing handle 15 can be used to conveniently push the marking cleaning device to move, and at the same time, the cleaning liquid can be added to the inside of the liquid storage tank 13 through the liquid filling port 14.

[0041] When the present embodiment is in use, the staff moves the marking cleaning device to the corresponding road surface through the pulley 2, and then starts the transmission mechanism to drive the second rotating shaft 34 to rotate. When the second rotating shaft 34 rotates, it will drive the mounting gear ring 20 of the outer wall to rotate. When the mounting gear ring 20 rotates, it will drive multiple mounting gear rings 20 meshingly connected to the outer wall to rotate at the same time, thereby driving multiple cleaning brush discs 21 at the bottom of the mounting gear ring 20 to rotate at the same time. The elastic arc plate 30 connected to the bottom of the mounting plate 1 can squeeze the limiting groove 35 of the outer wall of the support plate 27 through its own elastic force, thereby 0 provides an elastic force to press the support plate 27 downward, so that the cleaning brush disc 21 can rotate closely to the road surface when rotating. When the road surface is uneven, the mounting gear ring 20 as a whole will move up and down under the pressure of the road surface, thereby squeezing the elastic arc plate 30 through the support plate 27. At this time, the elastic arc plate 30 will buffer the pressure on the support plate 27 through its own elastic force, and at the same time, the cleaning brush disc 21 at the bottom of the mounting gear ring 20 will always rotate closely to the road surface under the elastic force of the elastic arc plate 30, thereby completely cleaning the markings on the uneven road surface.

[0042] The guide frame 9 and the guide plate 12 can guide the support plate 27 when it moves up and down, thereby improving the stability of the support plate 27 when it follows the ups and downs of the road surface. At the same time, the first support frame 7 and the second support frame 16 support the mounting plate 1 as a whole through multiple first elastic telescopic rods 26. The elastic force provided by the first elastic telescopic rods 26 can allow the cleaning, spraying and scraping mechanisms at the bottom of the mounting plate 1 to be close to the road surface.

[0043] Embodiment 2:

[0045] When this embodiment is in use, when the motor 24 drives multiple installed gear rings 20 to rotate, the second rotating shaft 34 on the outer wall of the installed gear ring 20 will drive the first transmission gear 5 on one side of the movable frame 22 to rotate, thereby driving a group of first brush plates 3 on the outer wall of the first rotating shaft 4 to rotate, sweeping away stones and other debris on the road surface, so that the cleaning liquid sprayed by the subsequent spraying mechanism can fall on the clean road surface.
