This foundation layer is usually constructed with plain concrete or broken stone concrete. After the construction is completed, the primary problem is to clean the dust accumulated on the roadbed pavement during the construction process, so as to reduce the interference of the dust on the subsequent further construction, so as to ensure the efficient performance of the subsequent construction.

[0003] To solve the above problems, a bridge roadbed pavement construction device is disclosed on the market, which comprises a moving box, a cleaning mechanism and a plurality of universal wheels. The universal wheels are arranged on the moving box. When the device is used, the moving box is moved, and the cleaning brush on the cleaning mechanism can sweep away the accumulated dust, thereby reducing the amount of dust accumulated on the roadbed pavement, that is, improving the efficiency and quality of the subsequent construction.

[0004] The above device has the following problems in actual use: when the device is used, the roadbed pavement will be cracked due to the problems caused by the construction, and thus part of the dust will be accumulated in the cracks, thereby interfering with the addition of the repair agent in the subsequent road maintenance, that is, reducing the repair effect of the repair agent, and causing safety hazards on the roadbed pavement. SUMMARY

[0005] The present application provides a highway bridge roadbed pavement construction device to solve the problem that the existing construction device cannot clean the dust in the cracks on the roadbed pavement.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: a highway bridge roadbed pavement construction device, comprising a movable construction box with a side wall opening, and further comprising a cleaning mechanism; the cleaning mechanism comprises a rotating shaft, a first piston cylinder, a first piston block, a dust sticking cylinder with a through hole in the side wall, a mounting plate for sealing the through hole, a dust suction pipe with a dust suction hole in the bottom, a plurality of dust guide holes equidistantly arranged along the circumferential direction of the dust sticking cylinder, a driving assembly for driving the rotating shaft to rotate, and a power assembly for driving the first piston block to make vertical reciprocating motion; the mounting plate is fixedly connected with the construction box; the rotating shaft is rotatably connected with the mounting plate; the dust sticking cylinder is fixedly connected with the rotating shaft; the dust suction pipe is fixedly connected with the mounting plate, and the dust suction hole is communicated with the dust guide hole; the first piston cylinder is fixedly connected with the mounting plate, and the first piston cylinder is respectively communicated with an air inlet pipe and an air outlet pipe, both of which are communicated with the dust suction pipe; the first piston block is slidably connected with the first piston cylinder.

[0007] The principle and advantages of the present application are as follows: During the moving of the construction box, the dust adhered to the roadbed and pavement can be adhered to the dust adhering cylinder through the rotation of the dust adhering cylinder, so that the dust on the roadbed and pavement is cleaned, and the efficiency and quality of the further treatment of the roadbed and pavement are improved.

[0008] During the adhering of the dust on the roadbed and pavement to the dust adhering cylinder, the first piston cylinder continuously pressurizes the dust suction pipe, so that when the dust guide hole is located above the crack, the pressure in the dust suction pipe can suck the dust in the crack into the dust suction pipe. Therefore, through the above movement, the dust in the crack is cleaned and collected, so that the maintenance and repair of the crack are prepared.

[0009] In summary, the dust on the roadbed and pavement is cleaned, and the dust in the crack of the roadbed and pavement is collected, so that the comprehensiveness of the dust cleaning and collection is improved.

[0010] Further, the collection assembly further comprises a connecting block, a scraping block, a collection pipe, a collection box with a collection hole in the side wall, and a collection part symmetrically arranged on both sides of the collection pipe along the width direction of the collection pipe; the collection box is fixedly connected with the construction box; the collection pipe is in communication with the collection box; the two ends of the connecting block are fixedly connected with the collection box and the scraping block respectively; the scraping block is attached to the dust adhering cylinder, and the collection hole faces the scraping block; the collection part comprises a second piston cylinder, a second piston block, and a movement unit for driving the second piston block to reciprocate along the length direction of the second piston cylinder; the second piston cylinder is fixedly connected with the collection pipe, and the second piston cylinder is communicated with a gas guide pipe and an exhaust pipe respectively, both of which are in communication with the collection pipe; the second piston block is in sliding connection with the second piston cylinder.

[0011] During the adhering of the dust to the dust adhering cylinder, the dust can be loosened by the interaction between the scraping block and the dust adhering cylinder. During the loosening of the dust, the loosened dust can move to the collection box through the collection hole under the suction of the second piston cylinder, so that the collection of the dust is completed.

[0012] Through the above movement, the amount of dust adhered to the dust adhering cylinder is reduced, so that the dust adhering cylinder can continuously and efficiently adhere and collect the dust on the roadbed and pavement. Moreover, through the collection of the dust, the probability of dust forming dust is reduced, that is, the pollution of the dust to the environment is reduced.

[0013] Further, the collection part further comprises a gas guide unit; the gas guide unit comprises a gas guide pipe, a gas guide shaft, a gas guide blade, and a power member for driving the gas guide shaft to rotate; the gas guide pipe is in communication with the collection pipe; the gas guide shaft is in rotational connection with the gas guide pipe; and the gas guide blade is fixedly connected with the gas guide shaft.

[0014] During the second piston cylinder pair sucking the dust into the collecting box, the suction force on the dust can be further increased with the help of the guide vane, so that the dust can be more fully and completely sucked into the collecting box, that is, the dust collection effect is enhanced.

[0015] Further, the scraping block is provided with a linkage block; the air guide unit further comprises a linkage member; the linkage member comprises a first cam, a first spring, and a linkage groove opened on the scraping block; the air guide shaft is rotatably connected with the collecting box and extends out of the collecting box, the first cam is fixedly connected with the air guide shaft; the linkage block is slidably connected with the linkage groove, the first cam abuts against the linkage block, and the surface of the dust sticking cylinder is located on the movement track of the linkage block; the two ends of the first spring are respectively connected with the linkage block and the linkage groove.

[0016] During the scraping block scraping the dust adhered on the surface of the dust sticking cylinder, the dust adhered on the surface of the dust sticking cylinder can be further scraped from the vertical direction through the vertical reciprocating movement of the linkage block, so that the dust is more fully loosened, and the dust is completely sucked into the collecting box.

[0017] Further, the cleaning part further comprises a cleaning shaft, a cleaning roller brush, a cleaning bottom groove opened on the scraping block, and a driving unit for driving the cleaning shaft to rotate; the cleaning shaft is rotatably connected with the cleaning bottom groove; the cleaning roller brush is fixedly connected with the cleaning shaft, and the cleaning roller brush is attached to the surface of the dust sticking cylinder.

[0018] During the rotation of the cleaning roller brush, the positions cleaned by the scraping block and the linkage block can be further processed, so that the amount of dust adhered on the dust sticking cylinder is further reduced, thereby preparing for the dust sticking cylinder to adhere the dust on the roadbed and pavement again. Therefore, under the action of the cleaning roller brush, the adhesion effect of the adhesion cylinder can be further enhanced, so that the adhesion cylinder can efficiently and fully adhere all the dust on the roadbed and pavement.

[0019] Further, the cleaning part further comprises a dredging unit; the dredging unit comprises an edge block, a dredging block, a sliding hole opened on the collecting box, and a moving member for driving the edge block to reciprocate along the length direction of the sliding hole; the edge block is slidably connected with the sliding hole; the dredging block is fixedly connected with the edge block, and the collecting hole is located on the movement track of the dredging block.

[0020] Through the reciprocating movement of the dredging block, the dust blocked in the collecting hole can be cleaned by the dredging block, so that the probability of the dust blocking the collecting hole is reduced, and the dust can be efficiently moved into the collecting box through the collecting hole.

[0021] Further, the power assembly comprises a second cam and a second spring; the second cam is fixedly connected with the rotating shaft, and the second cam abuts against the first piston block; the two ends of the second spring are respectively connected with the first piston cylinder and the first piston block.

[0022] During rotation of the rotation shaft, the second cam rotates synchronously. During rotation of the second cam, when the protruding part of the second cam abuts against the first piston block, the first piston block moves vertically downward, and the second spring is compressed; when the protruding part of the second cam no longer abuts against the first piston block, the first piston block is reset under the action of the second spring, and the first piston block moves vertically upward.

[0024] During rotation of the movement shaft, the third cam rotates synchronously. During rotation of the third cam, when the protruding part of the third cam abuts against the second piston block, the second piston block moves to the position close to the collecting pipe, and the third spring is compressed; when the protruding part of the third cam no longer abuts against the second piston block, the second piston block is reset under the action of the third spring, and the second piston block moves to the position away from the collecting pipe. Therefore, the second piston block can move reciprocatingly along the length direction of the second piston cylinder.

[0025] Further, the movement shaft is a worm, and the power member is a worm wheel; the worm wheel is fixedly connected with the air guide shaft, and the worm wheel is engaged with the worm.

[0026] During rotation of the worm, the worm and the worm wheel are engaged, and then the worm wheel drives the air guide shaft to rotate.

[0028] The principle and advantages of the present application are as follows: Through the cooperation of the dust sticking cylinder and the dust suction pipe, dust accumulated on the surface of the roadbed pavement and dust in the cracks of the roadbed pavement can be cleaned, thereby reducing the interference of dust on the subsequent construction of the roadbed pavement.

[0050] The movement shaft 25 is a worm; the power member is a worm gear 27; the worm gear 27 is fixedly connected with the air guide shaft 17, and the worm gear 27 is engaged with the worm.

[0051] The driving unit comprises a gear 28 and an annular rack 29; the gear 28 is fixedly connected with the cleaning shaft; the annular rack 29 is fixedly connected with the outer wall of the dust sticking cylinder 5 and is engaged with the gear 28.

[0052] The movement member comprises a sliding block 31, a fourth cam 32, a fourth spring 30 and a guide groove opened on the connecting block 10; the sliding block 31 is slidably connected with the guide groove and is fixedly connected with the side block 22; the fourth cam 32 is fixedly connected with the cleaning shaft and abuts against the sliding block 31; the fourth spring 30 is located in the guide groove, and two ends of the fourth spring 30 are connected with the sliding block 31 and the guide groove respectively.

[0053] The driving member is a belt 33; two ends of the belt 33 are sleeved on the driving shaft and the rotating shaft 2.

[0054] Specific implementation process: The construction box 1 is moved, and during the movement of the construction box 1, the motor is started, and then the rotating shaft 2 is driven to rotate by the output shaft of the motor. During the rotation of the rotating shaft 2, the dust sticking cylinder 5 rotates synchronously. Therefore, through the rotation of the dust sticking cylinder 5, the residual dust on the roadbed and pavement can be adhered, thereby realizing the cleaning of the dust on the roadbed and pavement, and improving the efficiency and quality of further processing of the roadbed and pavement.

[0055] During the rotation of the rotating shaft 2, the second cam 24 rotates synchronously. During the rotation of the second cam 24, when the protruding part of the second cam 24 abuts against the first piston block 4, the first piston block 4 moves vertically downward, and the second spring is compressed; when the protruding part of the second cam 24 no longer abuts against the first piston block 4, the first piston block 4 is reset under the action of the second spring, and the first piston block 4 moves vertically upward. Therefore, the first piston block 4 can move vertically reciprocatingly.

[0056] Therefore, during the adhesion of the dust on the roadbed pavement to the adhesion cylinder, the first piston cylinder 3 constantly pressurizes the dust suction pipe 7, and when the dust guide hole 8 is located above the crack, the pressure in the dust suction pipe 7 can suck the dust in the crack into the dust suction pipe 7. Therefore, through the above movement, the dust in the crack is cleaned and collected, thereby preparing for the subsequent maintenance and repair of the crack.

[0057] In summary, the dust on the roadbed pavement is cleaned, and the dust in the crack of the roadbed pavement is collected, thereby improving the comprehensiveness of the dust cleaning and collection.

[0058] During the rotation of the rotating shaft 2, the worm is driven to rotate by the belt 33. During the rotation of the worm, the third cam 26 rotates synchronously. During the rotation of the third cam 26, when the protruding part of the third cam 26 abuts against the second piston block 15, the second piston block 15 moves towards the position where the collection pipe 12 is located, and the third spring is compressed; when the protruding part of the third cam 26 no longer abuts against the second piston block 15, the second piston block 15 is reset under the action of the third spring and moves away from the position where the collection block is located. Therefore, the second piston block 15 can reciprocate along the length direction of the second piston cylinder 14.

[0059] Therefore, during the adhesion of the dust on the roadbed pavement to the adhesion cylinder, the first piston cylinder 3 constantly pressurizes the dust suction pipe 7, and when the dust guide hole 8 is located above the crack, the pressure in the dust suction pipe 7 can suck the dust in the crack into the dust suction pipe 7. Therefore, through the above movement, the dust in the crack is cleaned and collected, thereby preparing for the subsequent maintenance and repair of the crack.

[0060] Through the above movement, the amount of dust adhered to the dust adhesion cylinder 5 is reduced, thereby enabling the dust adhesion cylinder 5 to continuously and efficiently adhere and collect the dust on the roadbed pavement. Moreover, through the collection of the dust, the probability of dust forming dust is reduced, i.e., the pollution of the dust to the environment is reduced.

[0061] During the rotation of the worm, the worm gear 27 is driven to rotate by the meshing of the worm and the worm gear 27, and the air guide shaft 17 is driven to rotate by the worm gear 27. During the rotation of the air guide shaft 17, the air guide blade 18 rotates synchronously. Therefore, during the suction of the dust into the collection box 13 by the second piston cylinder 14, the suction force on the dust can be further increased with the assistance of the air guide blade 18, thereby enabling the dust to be more fully and completely sucked into the collection box 13, i.e., the collection effect of the dust is enhanced.

[0062] During the rotation of the air guide shaft 17, the first cam 20 rotates synchronously. During the rotation of the first cam 20, when the convex part of the first cam 20 abuts against the linkage block 19, the linkage block 19 moves vertically downward, and the first spring is compressed; when the convex part of the first cam 20 no longer abuts against the linkage block 19, the linkage block 19 is reset under the drive of the first spring, and the linkage block 19 moves vertically upward. Therefore, the linkage block 19 can move vertically reciprocatingly.

[0063] During the scraping of the dust adhered to the surface of the dust adhering cylinder 5 by the scraper 11, the vertical reciprocating movement of the linkage block 19 can further scrape the dust adhered to the surface of the dust adhering cylinder 5 from the vertical direction, so as to make the dust loose more fully, that is, the dust is sucked into the collecting box 13 completely.

[0064] During the rotation of the dust adhering cylinder 5, the annular rack 29 rotates synchronously. During the rotation of the annular rack 29, the gear 28 is driven to rotate through the meshing of the annular rack 29 and the gear 28. During the rotation of the cleaning shaft, the cleaning roller brush rotates synchronously.

[0065] During the rotation of the cleaning roller brush, the positions cleaned by the scraper 11 and the linkage block 19 can be further processed, so as to further reduce the amount of dust adhered to the dust adhering cylinder 5, thereby preparing for the dust adhering cylinder 5 to adhere the dust on the roadbed and pavement again. Therefore, under the action of the cleaning roller brush, the adhesion effect of the dust adhering cylinder can be further enhanced, so that the dust adhering cylinder can efficiently and fully adhere the dust on the roadbed and pavement completely.

[0066] During the rotation of the cleaning shaft, the fourth cam 32 rotates synchronously. During the rotation of the fourth cam 32, when the convex part of the fourth cam 32 abuts against the sliding block 31, the sliding block 31 drives the edge block 22 to move away from the position where the collecting hole is located, and the fourth spring 30 is compressed; when the convex part of the fourth cam 32 no longer abuts against the sliding block 31, the sliding block 31 is reset under the drive of the fourth spring 30, and the sliding block 31 drives the edge block 22 to move to the position close to the collecting hole. Therefore, the dredging block 23 can continuously approach or move away from the collecting hole.

[0067] Through the reciprocating movement of the dredging block 23, the dredging block 23 can clean the dust blocked in the collecting hole, thereby reducing the probability of dust blocking the collecting hole, that is, promoting the dust to move into the collecting box 13 through the collecting hole efficiently.

[0068] As described above, the dust on the roadbed and pavement and the dust in the cracks of the roadbed and pavement are cleaned, thereby improving the comprehensiveness of dust cleaning. The dust is collected into the collecting box 13, thereby reducing the probability of dust forming dust, that is, preparing for the subsequent centralized treatment of the dust.

Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application.
