Description

Technical Field

[0001] This invention relates to the field of highway maintenance technology, specifically a highway maintenance and cleaning device. Background Technology

[0002] After highways are put into use, regular road surface maintenance and cleaning are required to ensure the cleanliness of the road surface and the safety of vehicles. Highway maintenance and cleaning equipment mainly uses sweeper trucks, which consist of continuously rotating sweeping discs equipped with many fiber bristles that clean the ground as they rotate.

[0003] During the patent application process, a search revealed a Chinese patent with patent number CN223373650U: a highway maintenance and sweeping device. This device features a lifting mechanism and a detachable mechanism. When the sweeping disc needs replacement, the lifting mechanism moves the lifting box upwards, causing the sweeping disc to move upwards as well, facilitating subsequent operations. The operator first pulls the limiting rod upwards using a pull plate to release the limiting on the turntable. Then, by rotating the turntable, the rotation causes the threaded rod to rotate, moving it outwards from the inside of the threaded hole. This causes the locking block to leave the inside of the locking groove, and the locking block retracts into the groove, releasing the limiting on the mounting base. The mounting base can then be removed from the inside of the mounting groove for replacement of the sweeping disc. This utility model facilitates the disassembly and assembly of the sweeping disc, making replacement convenient.

[0004] However, the above solution uses two sweeping discs for cleaning during use, without any side auxiliary sweeping components. During operation, it can only cover a local area directly below the lifting box. Dust or debris is easily left on the corners of the road surface and on both sides of the device's movement trajectory. The coverage width of a single sweep is limited, resulting in low operating efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a highway maintenance and cleaning device to achieve the above-mentioned objectives.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highway maintenance and sweeping device, comprising: a base, a dust collection box fixed at the upper end of the base, two motors fixedly connected to the upper end of the base, a sweeping brush fixedly connected to the output end of each of the two motors, and a collection component for gathering impurities provided on the front side of the base.

[0007] The collection assembly includes a mounting frame, which is fixedly connected to the front side of the base. A rotating rod is rotatably connected to the inner front wall of the mounting frame, and a cleaning frame is fixedly connected to the outer side wall of the rotating rod. Two hinge seats are fixedly connected to the upper end of the cleaning frame, and two limiting shafts are rotatably connected to the lower end of the cleaning frame. A gathering arm is fixedly connected to the outer side wall of each of the two limiting shafts, and a cleaning brush is fixedly connected to the lower end of each of the two gathering arms. An electric telescopic rod is fixedly connected to the rear side of the cleaning frame, and a movable seat is fixedly connected to the output end of the electric telescopic rod. The two ends of the movable seat are rotatably connected to connecting rods via rotating shafts. A vibration assembly is provided on one side of the mounting frame.

[0008] Preferably, two guide rods are fixedly connected to the rear side of the sweeping frame, and both guide rods pass through the left and right sides of the movable seat and are slidably connected thereto.

[0009] Preferably, the collecting assembly further includes a hydraulic rod fixedly connected to the upper end of the mounting frame. The output end of the hydraulic rod is fixedly connected to a lifting frame, and the lifting frame is slidably connected to the inner wall of the mounting frame. Two symmetrical hinge seats are fixedly connected to the front side of the lifting frame. The inner walls of the two hinge seats are rotatably connected to a pull rod through a pivot. The ends of the two pull rods away from the hinge seats are rotatably connected to the two hinge seats respectively.

[0010] Preferably, the vibration assembly includes a housing fixedly connected to the side wall of the mounting bracket. Two shafts are rotatably connected to the inner wall of the housing. Gears are fixedly connected to the outer walls of both shafts, and the two gears are meshed together. One end of one shaft is fixedly connected to a rotating rod, and the other shaft is fixedly connected to a connecting rod. Multiple rubber rods are fixedly connected to one end of the rotating rod through the outer wall of the housing. One end of each of the multiple rubber rods is fixedly connected to a striking block.

[0011] Preferably, a stop block is fixedly connected to one side of the sweeping frame, and the striking block abuts against the stop block when the rotating rod rotates.

[0012] Preferably, the ends of the two connecting rods furthest from the movable seat are rotatably connected to the two converging arms via a rotating shaft.

[0013] Preferably, an air pump is fixedly connected to the front side of the dust collection box and the upper end of the base. The air pump is connected to the dust collection box through a hose, and a suction head is fixedly connected to the output end of the air pump through the base.

[0014] Preferably, four casters are fixedly connected to the lower end of the base, the four casters are arranged symmetrically, and a push handle is fixedly connected to one side of the base.

[0015] Compared with the prior art, the present invention provides a highway maintenance and cleaning device, which has the following beneficial effects:

[0016] The moving base is driven by an electric telescopic rod, which, in conjunction with a connecting rod, drives two converging arms to open and close synchronously. This gathers dust and impurities from both sides of the base towards the center, effectively covering the areas on both sides of the moving device and improving cleaning efficiency. Simultaneously, two motors at the top of the base drive one cleaning brush, while a second cleaning brush is installed at the lower end of the converging arm of the collection component. Multiple sets of cleaning brushes work together to further expand the cleaning coverage width and significantly improve road cleaning efficiency. The cleaning frame can rotate on the mounting frame via a rotating rod, allowing for flexible adjustment of the tilt angle of the second cleaning brush. This adapts to different road slopes and ensures that the second cleaning brush remains in close contact with the road surface. Furthermore, when the device is not in use, a hydraulic rod drives the lifting frame to rise and fall. In conjunction with a pull rod, the cleaning frame can be rotated around the rotating rod to lift the cleaning frame, making it easy for staff to inspect the converging arms and replace the second cleaning brush. The cleaning frame can also be folded to reduce the floor space occupied.

[0017] When the connecting rod rotates, it drives one of the shafts to rotate. Through two meshing gears, it drives the other shaft and the rotating rod to rotate synchronously. The rubber rod and the striking block on the rotating rod periodically strike the stop on the sweeping frame, using vibration to shake off the dust adsorbed on the sweeping frame.

[0026] Please see Figure 1-6 The present invention provides a technical solution for a highway maintenance and cleaning device, comprising: a base 1, a dust collection box 2 fixed at the upper end of the base 1, and a discharge port on one side of the dust collection box 2 to facilitate the discharge of dust and impurities; two motors 3 fixedly connected to the upper end of the base 1, and a cleaning brush 4 fixedly connected to the output end of each of the two motors 3; and a collection component 5 for gathering impurities is provided on the front side of the base 1.

[0027] The collecting component 5 includes a mounting frame 501, which is fixedly connected to the front side of the base 1. A rotating rod 510 is rotatably connected to the inner wall of the front side of the mounting frame 501. A cleaning frame 502 is fixedly connected to the outer wall of the rotating rod 510. Two hinge seats 503 are fixedly connected to the upper end of the cleaning frame 502. Two limiting shafts 504 are rotatably connected to the lower end of the cleaning frame 502. A gathering arm 505 is fixedly connected to the outer wall of each of the two limiting shafts 504. A cleaning brush 506 is fixedly connected to the lower end of each of the two gathering arms 505. An electric telescopic rod 507 is fixedly connected to the rear side of the cleaning frame 502. A movable seat 508 is fixedly connected to the output end of the electric telescopic rod 507. A connecting rod 509 is rotatably connected to both ends of the movable seat 508 through a rotating shaft. A vibration component 6 is provided on one side of the mounting frame 501. The moving base 508 is moved by the electric telescopic rod 507, and the two gathering arms 505 are opened and closed synchronously by the connecting rod 509. This can gather the dust and impurities on both sides of the base 1 towards the center, improving the efficiency of road sweeping. In addition, the sweeping frame 502 can be rotated on the mounting frame 501 by the rotating rod 510, which makes it easy to adjust the tilt angle of the second sweeping brush 506 to adapt to the road slope and ensure that the second sweeping brush 506 is always in close contact with the road surface, avoiding the leakage of impurities due to uneven road surface and improving sweeping stability.

[0028] Two guide rods 5011 are fixedly connected to the rear side of the sweeping frame 502. Both guide rods 5011 pass through the left and right sides of the movable seat 508 and are slidably connected to it. When the electric telescopic rod 507 drives the movable seat 508 to move through the two guide rods 5011, it is to prevent the movable seat 508 from shifting or tilting, and to ensure that the movable seat 508 slides smoothly along the guide rods 5011.

[0029] The collecting component 5 also includes a hydraulic rod 51 fixedly connected to the upper end of the mounting frame 501. The output end of the hydraulic rod 51 is fixedly connected to a lifting frame 52, which is slidably connected to the inner wall of the mounting frame 501. Two symmetrical hinge seats 53 are fixedly connected to the front side of the lifting frame 52. Each hinge seat 53 has a pull rod 54 rotatably connected to its inner wall via a pivot. The ends of the two pull rods 54 away from the hinge seats 53 are rotatably connected to the two hinge seats 503 respectively. The height of the lifting frame 52 can be adjusted via the hydraulic rod 51. The lifting frame 52 pulls the sweeping frame 502 around the rotating rod 510 via the pull rods 54, thereby raising the sweeping frame 502 for easy inspection of the converging arm 505 or replacement of the second sweeping brush 506.

[0030] The vibration assembly 6 includes a housing 601 fixedly connected to the side wall of the mounting bracket 501. Two shafts 602 are rotatably connected to the inner wall of the housing 601. Gears 603 are fixedly connected to the outer walls of both shafts 602, and the two gears 603 are meshed together. One end of one shaft 602 is fixedly connected to a rotating rod 604, and the other shaft 602 is fixedly connected to a connecting rod 509. Multiple rubber rods 605 are fixedly connected to one end of the rotating rod 604, which passes through the outer wall of one end of the housing 601. Each rubber rod 605 has a striking block 606 fixedly connected to one end. Through the interaction between the multiple rubber rods 605 on the rotating rod 604 and the striking block 606, when the rotating rod 604 rotates, the striking block 606 periodically strikes the sweeping frame 502, generating vibration and causing the dust adsorbed on the sweeping frame 502 to fall off.

[0031] A stop block 5021 is fixedly connected to one side of the sweeping frame 502. When the rotating rod 604 rotates, the striking block 606 abuts against the stop block 5021. The stop block 5021 can prevent the striking block 606 from directly hitting the body of the sweeping frame 502, thus extending the service life of the sweeping frame 502.

[0032] The ends of the two connecting rods 509 furthest from the movable base 508 are rotatably connected to the two gathering arms 505 via rotating shafts. The two connecting rods 509 pull the two gathering arms 505 to rotate along the limiting shaft 504, thereby gathering the dust and impurities on both sides of the base 1 towards the center, improving cleaning efficiency.

[0033] An air pump 201 is fixedly connected to the front of the dust collection box 2 and to the upper end of the base 1. The air pump 201 is connected to the dust collection box 2 via a hose. Both the air pump 201 and the dust collection box 2 are existing technologies used for collecting dust, and will not be described further. The output end of the air pump 201 passes through the base 1 and is fixedly connected to a suction head 202. The suction head 202 can quickly suck the collected impurities into the dust collection box 2 for collection.

[0034] Four casters 101 are fixedly connected to the lower end of the base 1. The four casters 101 are symmetrically arranged and are self-locking. A push handle 102 is fixedly connected to one side of the base 1. The cooperation between the casters 101 and the push handle 102 facilitates the movement of the entire device and improves its flexibility.

[0035] In practical use, this invention serves as a highway maintenance and cleaning device. During operation, workers can move the device to the area to be cleaned using the push handle 102 and the universal wheels 101. During cleaning, two motors 3 are activated to output cleaning brushes 4 for cleaning. Simultaneously, an electric telescopic rod 507 is activated to output a moving seat 508 that slides along two guide rods 5011. As the moving seat 508 moves, the connecting rod 509, connected by rotating shafts at both ends, drives two gathering arms 505 to rotate and open / close synchronously around the limiting shaft 504 at the lower end of the cleaning frame 502. This adjusts the gathering range of the cleaning brushes 506 at the lower end of the two gathering arms 505. The cleaning brushes 506 move with the gathering arms 505, gathering dust, gravel, fallen leaves, and other impurities scattered on both sides of the base 1 towards the central area of ​​the device, preventing incomplete cleaning due to dispersed impurities and improving overall cleaning efficiency.

[0036] When the device is not in use, the hydraulic rod 51 can be activated to output the lifting frame 52 to slide up and down along the inner wall of the mounting frame 501. When the lifting frame 52 slides, the pull rod 54 pulls the sweeping frame 502 to rotate around the rotating rod 510, thereby retracting the sweeping frame 502. In addition, the tilt angle of the sweeping frame 502 can be adjusted by the hydraulic rod 51 to ensure that the sweeping brush 506 is always in close contact with the road surface, avoiding the leakage of impurities caused by uneven road surfaces. When the hydraulic rod 51 drives the lifting frame 52 to rise... The rotating rod 510 rotates, which in turn drives the gear 603 to rotate. Since the two gears 603 mesh, they drive the rotating rod 604 to rotate. The rotating rod 604 rotates, which drives the striking block 606 to rotate, periodically striking the stop block 5021 on one side of the sweeping frame 502 and generating vibration. This vibration is transmitted to the sweeping frame 502 and the second sweeping brush 506, causing dust or small gravel and other impurities attached to the second sweeping brush 506 and the gathering arm 505 to fall off, making it easier for staff to check or replace the second sweeping brush 506 later.
