Description

Technical Field

[0001] This invention relates to the field of road maintenance technology, and in particular to a preventive maintenance device for elevated roads. Background Technology

[0002] Elevated roads are primarily constructed to improve vehicle speed or address safety issues arising from intersections with railways or pedestrian crossings. They are designed without traffic lights, connecting to ground-level roads via ramps and grade-separated interchanges to avoid direct intersections. By applying a recycling agent, the oxidized asphalt layer of the elevated road is restored, enhancing asphalt adhesion, filling micro-cracks, preventing water seepage, reducing water loss through fatigue cracks, extending pavement life, and saving on maintenance costs.

[0003] During spraying, a filter is required to filter the regenerant to prevent uneven application and blockage of pipes or nozzles, ensuring uniform spraying.

[0004] Currently, there is a lack of equipment that can perform multi-stage filtration of regenerants, separating larger clumps and fine impurities, preventing fuel injectors from becoming clogged, and allowing the fuel injectors to swing and spray out the regenerant to achieve road maintenance.

[0005] Therefore, in response to the above problems, a preventive maintenance device for elevated roads is proposed to solve these problems. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by developing a preventive maintenance device for elevated roads. This invention can achieve multi-stage filtration of the regenerant, separating larger clumps and fine impurities, preventing the fuel injectors from becoming clogged, and allowing the fuel injectors to swing and spray the regenerant to achieve road maintenance.

[0007] The technical solution to the technical problem solved by this invention is as follows: This invention provides a preventive maintenance device for elevated roads, including an installation component, a filtration component, and a spraying component; the installation component includes a main mounting plate, which is connected to symmetrical L-shaped frames and a bracket; the filtration component includes a dome-shaped square box, which is connected to the main mounting plate, with a feed pipe fixedly connected to the dome-shaped square box at its dome top, and symmetrical arc plates connected inside the dome-shaped square box, forming slots, with one arc plate connected to a partition plate, the partition plate having a set of large filter holes; the dome-shaped square box is fixed... A central connecting pipe connects the partition plate and an arc plate forming an area. The central connecting pipe is fixedly connected to a first square box, which in turn connects to a second square box. The first square box has a set of filter holes to connect it to the second square box. The second square box is fixedly connected to a discharge pipe. The spraying assembly includes a spray pipe rotatably connected to symmetrical L-frames. The spray pipe passes through the brackets and is connected to a set of mounting plates. Each mounting plate is rotatably connected to a nozzle seat, and each nozzle seat is connected to an oil injector. By using a filter assembly, the regenerant is filtered, preventing impurities from clogging the oil injectors and causing uneven spraying. The spraying assembly enables the spraying of the regenerant, with the oil injectors evenly spraying the regenerant onto the road surface, thus maintaining the elevated road.

[0008] As an optimization, the bracket connects to a fixed gear, the spray pipe passes through the fixed gear, the spray pipe connects to a mounting bracket, the mounting bracket is bearing-connected to the central shaft of a swing gear, the swing gear meshes with the fixed gear, the central shaft of the swing gear connects to a driving bevel gear, the driving bevel gear meshes with a driven bevel gear, the central shaft of the driven bevel gear is bearing-connected to the mounting bracket, the central shaft of the driven bevel gear connects to a spray turntable, spray blocks are connected to the edge of the spray turntable, the spray blocks are set in straight grooves, the straight grooves connect to a long rod, the long rod passes through the mounting bracket, the long rod connects to a set of power blocks, the set of power blocks are respectively set in straight grooves, each straight groove is connected to a corresponding nozzle seat. By using gear meshing and bevel gear meshing, the injector nozzles reciprocate in the left-right direction, spraying regenerant onto the road surface.

[0009] As an optimization, the dome-shaped square box is connected to an anti-clogging component, which includes a rotating impeller. The central shaft of the rotating impeller is connected to the dome-shaped square box, and the rotating impeller is matched with symmetrical arc plates. The central shaft of the rotating impeller is connected to an anti-clogging turntable, and an anti-clogging circular block is connected to the eccentric part of the anti-clogging turntable. The dome-shaped square box is connected to a guide block, and the anti-clogging circular block is set in the upper horizontal groove. The upper horizontal groove is connected to a vertical rod, which passes through the guide block. The vertical rod is connected to a set of lower horizontal grooves. The dome-shaped square box is rotatably connected to the rotating shafts of a set of staggered lower filter plates. The rotating shaft of each lower filter plate is connected to a lower L-shaped rod, and the circular rod of each lower L-shaped rod is set in the corresponding lower horizontal groove. By using a rotating impeller, the regenerant enters the dome-shaped box along the inlet. Larger impurities move downwards and contact the lower filter plate in sequence from top to bottom. The lower filter plate swings back and forth and always remains tilted downwards, causing the impurities to gradually move downwards to the bottom of the dome-shaped box. Due to the obstruction of the lower filter plate, they will not return to the top of the dome-shaped box.

[0010] As an optimization, the dome-shaped box is rotatably connected to the shaft of the upper filter plate. The shaft of the upper filter plate is connected to the upper L-shaped rod, the vertical rod is connected to the middle horizontal groove, the round rod of the upper L-shaped rod is set in the middle horizontal groove, the partition plate is connected to the arc-shaped baffle, and the upper filter plate matches the arc-shaped baffle. By using the upper filter plate, the upper filter plate reciprocates and always maintains contact with the arc-shaped baffle, preventing larger impurities from accumulating at the partition plate. When the upper filter plate swings downward and contacts the impurities, it drives the impurities to move obliquely downward, causing them to contact the lower filter plate, and gradually moving the impurities downward to the bottom of the dome-shaped box.

[0011] As an optimization, the anti-clogging block is rotatably connected to a transmission assembly, which includes a main boom. The anti-clogging block is rotatably connected to one end of the main boom, and the other end of the main boom is rotatably connected to a power arm, which is connected to the spraying pipe. By using the main boom and power arm, the power arm drives the entire spraying assembly to move, causing the nozzles to swing back and forth in the front-to-back direction, spraying the regenerator onto the road surface. This, combined with the left-to-right swinging of the nozzles, achieves uniform spraying of the regenerator.

[0012] As an optimization, the second square box bearing connects to the central shaft of the turntable, and a circular block is connected to the eccentric part of the turntable. The circular block is set in a vertical groove. The second square box is connected to symmetrical guide crossbars, which pass through the ejector plate. The vertical groove connects to the ejector plate, and the ejector plate connects to a set of ejector pins. Each set of ejector pins matches a set of filter holes, and the ejector plate is provided with a set of filter holes. By using the ejector plate, the ejector plate moves back and forth, causing the ejector pins to repeatedly enter the filter holes, preventing the filter holes from being blocked. The reciprocating entry of the ejector pins into the filter holes causes a change in pressure inside the second square box, promoting the movement of the regenerant and allowing it to enter the spray pipe.

[0013] As an optimization, the transmission assembly further includes a first synchronous pulley and a second synchronous pulley. The central shaft of the rotating impeller is connected to the first synchronous pulley, and the central shaft of the turntable is connected to the second synchronous pulley. One end of the synchronous belt wraps around the first synchronous pulley, and the other end of the synchronous belt wraps around the second synchronous pulley. By employing a synchronous pulley mechanism, the rotational motion of the rotating impeller is transmitted to the turntable, providing power for the movement of the ejector pin.

[0014] As an optimization, the fuel injector can produce a high-impact fan-shaped spray with a spray angle θ of 0º-95º and uniform spray distribution.

[0015] As an optimization, the nozzle opening is provided with an opening slit, and the center line of the opening slit is at an angle of 10º-15º to the axis of the spray pipe.

[0016] As an optimization, the spray pipe should be 350-450mm above the ground, the distance between adjacent nozzles should be 200-400mm, and the spray width should overlap, with at least two nozzles spraying regenerant at the same location.

[0017] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects: 1. This device employs an upper filter plate, which reciprocates and maintains constant contact with the arc-shaped baffle, preventing larger impurities from accumulating at the separator. When the upper filter plate swings downward and contacts the impurities, it causes the impurities to move diagonally downward, contacting the lower filter plate and gradually moving them to the bottom of the dome-shaped box. Larger impurities will move downward and contact the lower filter plate sequentially from top to bottom. The lower filter plate reciprocates and always remains tilted downward, causing the impurities to gradually move downward to the bottom of the dome-shaped box and preventing them from returning to the top of the dome-shaped box due to the obstruction of the lower filter plate.

[0018] 2. This device uses a pin plate that moves back and forth, causing the pins to repeatedly enter the filter holes, preventing the filter holes from becoming clogged. The reciprocating movement of the pins into the filter holes causes a change in pressure inside the second chamber, promoting the movement of the regenerant and allowing it to enter the spray pipe.

[0019] 3. This device uses a spraying assembly, with the power arm driving the spraying assembly to move as a whole, so that the nozzle can swing back and forth in the front and back direction; and uses gear meshing and bevel gear meshing to swing the nozzle back and forth in the left and right direction. The combination of the back and forth and left and right swinging of the nozzles can achieve uniform spraying of the regenerant. Attached Figure Description

[0036] The dome-shaped box 11 is connected to the anti-clogging component 5 by a bearing. The anti-clogging component 5 includes a rotating impeller 51. The central shaft of the rotating impeller 51 is connected to the dome-shaped box 11 by a bearing. The rotating impeller 51 is matched with the symmetrical arc plate 19. The central shaft of the rotating impeller 51 is connected to the anti-clogging turntable 52.

The lower filter plate 56 swings back and forth and always remains tilted downwards, so that the impurities gradually move downwards to the bottom of the dome box 11 and will not return to the top of the dome box 11 due to the obstruction of the lower filter plate 56.

[0037] The anti-clogging block 511 is rotatably connected to the transmission assembly 2. The transmission assembly 2 includes a large arm 25.

[0038] The fuel injector 44 can produce a high-impact fan-shaped spray with a spray angle θ of 0º-95º and uniform spray distribution.

[0039] The nozzle 44 has an opening slit at its opening, and the center line of the opening slit is at an angle of 10º-15º to the axis of the spray pipe 41.

[0040] The spray pipe 41 should be 350-450mm above the ground, the distance between adjacent nozzles 44 should be 200-400mm, and the spray width should overlap. The same location should receive regenerant sprayed by at least two nozzles 44.

[0041] The first box 15 and the second box 16 are respectively connected to the mounting main board 31 by a set of support rods.

[0042] The workflow of this embodiment is as follows: Connect one end of a hose to the discharge pipe 114 and the other end to the spray pipe 41. Connect the fuel injector 44 to the spray pipe 41 via the hose. Connect the feed pipe 13 to the feed pump on the regenerant source. The feed pump can be used to achieve continuous feeding, and the flow of regenerant drives the rotating impeller 51 to rotate. Alternatively, an external motor can be used, connected to the central shaft of the rotating impeller 51, so that the rotation of the motor drives the rotating impeller 51 to rotate.

[0043] The rotating impeller 51 drives the anti-clogging turntable 52 to rotate. The anti-clogging turntable 52 drives the anti-clogging block 511 to swing along the upper horizontal groove 53.

The large arm 25 drives the power arm 24 to swing back and forth. The power arm 24 drives the spraying assembly 4 to move. The swing gear 45 of the spraying assembly 4 meshes with the fixed gear 34 and rotates during the swinging process. The swing gear 45 drives the active bevel gear 410 to rotate back and forth. The active bevel gear 410 drives the driven bevel gear 49 and the spraying turntable 412 to rotate back and forth. The spraying turntable 412 drives the spraying block 414 to swing in the straight groove 413. The spraying block 414 drives the straight groove 413 to move back and forth.

[0044] Example 2: This example further elaborates on Example 1. The dome-shaped box 11 is rotatably connected to the shaft of the upper filter plate 54.

The round rod of the upper L-shaped rod 55 is disposed in the middle horizontal groove 510. The partition plate 111 is connected to the arc-shaped baffle 112, and the upper filter plate 54 matches the arc-shaped baffle 112. By using the upper filter plate 54, the upper filter plate 54 reciprocates and maintains contact with the arc-shaped baffle 112, preventing larger impurities from accumulating at the partition plate 111. When it swings downward and contacts the impurities, it drives the impurities to move obliquely downward, causing them to contact the lower filter plate 56, so that the impurities gradually move downward to the bottom of the dome-shaped box 11.

[0045] The workflow of this embodiment is as follows: The vertical rod 59 drives the middle horizontal groove 510 to move back and forth, the middle horizontal groove 510 drives the upper L rod 55 to swing back and forth, and the upper L rod 55 drives the upper filter plate 54 to swing back and forth.

[0046] Example 3: This example further elaborates on Example 1 or 2. The second square box 16 is connected to the central shaft of the turntable 516. A circular block 517 is connected to the eccentric part of the turntable 516. The circular block 517 is set in the vertical groove 515. The second square box 16 is connected to symmetrical guide bars 17, which pass through the ejector plate 512. The vertical groove 515 is connected to the ejector plate 512. The ejector plate 512 is connected to a set of ejector pins 513. The set of ejector pins 513 matches a set of filter holes 18. The ejector plate 512 is provided with a set of filter holes 514. By using the ejector plate 512, the ejector plate 512 moves back and forth, causing the ejector pins 513 to reciprocate into the filter holes 18, preventing the filter holes 18 from being blocked. The reciprocating movement of the ejector pins 513 into the filter holes 18 causes a change in pressure inside the second square box 16, promoting the movement of the regenerant and allowing it to enter the spray pipe 41.

[0047] The transmission assembly 2 further includes a first synchronous pulley 21 and a second synchronous pulley 23. The central shaft of the rotating impeller 51 is connected to the first synchronous pulley 21, and the central shaft of the turntable 516 is connected to the second synchronous pulley 23. One end of the synchronous belt 22 surrounds the first synchronous pulley 21, and the other end of the synchronous belt 22 surrounds the second synchronous pulley 23. By employing a synchronous pulley mechanism, the rotational motion of the rotating impeller 51 is transmitted to the turntable 516, providing power for the movement of the ejector pin 513.

[0048] The workflow of this embodiment is as follows: The rotating impeller 51 drives the first synchronous wheel 21 to rotate, the first synchronous wheel 21 drives the synchronous belt 22 to move, the synchronous belt 22 drives the second synchronous wheel 23 and the turntable 516 to rotate, the turntable 516 drives the round block 517 to swing in the vertical groove 515, the round block 517 drives the vertical groove 515 to move back and forth, the vertical groove 515 drives the ejector plate 512 to move back and forth along the guide bar 17, the ejector plate 512 drives the ejector pin 513 to move back and forth and enter the filter hole 18, and push out the fine impurities remaining in the filter hole 18.

[0049] This device employs an upper filter plate 54, which reciprocates and remains in contact with the arc-shaped baffle 112, preventing larger impurities from accumulating at the separator 111. When the upper filter plate 54 swings downward and contacts the impurities, it causes the impurities to move diagonally downward and contact the lower filter plate 56, allowing the impurities to gradually move downward to the bottom of the dome-shaped box 11. Larger impurities will move downward and contact the lower filter plate 56 sequentially from top to bottom. The lower filter plate 56 reciprocates and remains tilted downward, causing the impurities to gradually move downward to the bottom of the dome-shaped box 11, and will not return to the top of the dome-shaped box 11 due to the obstruction of the lower filter plate 56.

[0050] This device employs a pin plate 512, which moves back and forth, causing the pin 513 to repeatedly enter the filter orifice 18, thus preventing the filter orifice 18 from becoming clogged. The reciprocating entry of the pin 513 into the filter orifice 18 causes a change in pressure within the second box 16, promoting the movement of the regenerant and allowing it to enter the spray pipe 41.

[0051] This device uses a spraying assembly 4, and the power arm 24 drives the spraying assembly 4 to move as a whole, so that the nozzle 44 swings back and forth in the front and back direction; by using gear meshing and bevel gear meshing, the nozzle 44 swings back and forth in the left and right direction; the back and forth and left and right swinging of the nozzle 44 are combined to achieve uniform spraying of regenerant.

[0052] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
