Description

Technical Field

[0001] This invention relates to the field of road sealant equipment technology, specifically to a road sealant equipment. Background Technology

[0002] Road sealant equipment is a specialized set of equipment used in highway maintenance engineering to seal and repair cracks in asphalt and cement concrete pavements. Its core function is to deliver and precisely inject sealant, thereby filling road cracks to prevent water and debris from entering, delaying the spread of road damage, and extending the service life of the road. It is a common road construction equipment.

[0003] The applicant discovered through a search that a Chinese patent discloses "a road surface crack sealant application device" with publication (announcement) number "CN223189552U". This patent mainly uses the discharge direction of the discharge component to drive and adjust the discharge direction. When the equipment moves forward, the discharge direction of the discharge component is controlled at any time to keep it on the trajectory of the road surface crack. This allows for precise control of the sealant's repair of the crack location. However, during the use of the above patent, if the crack wall is not thoroughly cleaned, residual dust, slag and other impurities may form a separating film between the sealant and the crack wall, completely blocking effective adhesion. In this case, the sealant only sticks to the dust, and the adhesion between the dust and the crack wall is extremely weak. Under traffic load and temperature changes, the sealant can easily be peeled off in one piece.

[0004] To solve the above problems, we propose a road surface sealing equipment. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a road surface sealing adhesive device, including a fixed frame, a protective shell fixedly installed on the top surface of the fixed frame, a front wheel frame fixedly installed on one side of the bottom surface of the fixed frame, a caster wheel fixedly installed on the side of the bottom surface of the fixed frame away from the front wheel frame, and a storage component provided inside the protective shell on the side near the front wheel frame.

[0006] The front wheel frame includes a connecting shell fixedly mounted on the bottom surface of the fixed frame. A conversion component is provided on one side of the connecting shell, and output wheels are provided on both the side of the conversion component away from the protective shell and the side of the connecting shell.

[0007] Furthermore, the conversion assembly includes a fixed cylinder embedded in one side of the surface of the connecting shell. A planetary reducer is fixedly installed on the side of the fixed cylinder away from the connecting shell. A power disk is rotatably installed on the inner wall of the fixed cylinder. A cleaning cylinder is rotatably installed on the surface of the planetary reducer and the surface of the fixed cylinder. A plurality of cleaning components are equidistantly arranged on the outer peripheral wall of the cleaning cylinder along its circumference. Each cleaning component extends along the axial direction of the cleaning cylinder, and the angle between the central axis of two adjacent cleaning components and the central axis of the cleaning cylinder is equal.

[0008] An impeller is fixedly installed on the side of the power disk away from the planetary reducer. A dust extraction cylinder is fixedly installed on the bottom surface of the fixed cylinder away from the impeller. A U-shaped guide tube is fixedly installed on the periphery of the impeller. Magnetic blocks are embedded in the surface of the power disk and the corresponding positions on the inner wall of the cleaning cylinder.

[0009] Furthermore, the planet carrier in the planetary reducer is fixedly connected to the surface of the fixed cylinder and does not participate in rotation. The sun gear in the planetary reducer serves as the output end and is fixedly connected to the surface of the power disk. The planet gears in the planetary reducer serve as the input end and are fixedly connected to the surface of one of the output gears, rotating around the fixed planet carrier axis. One end of the U-shaped guide tube extends through to one side of the connecting shell. By utilizing the planetary reducer, the rotational speed of the output gear can be amplified. This allows the cleaning components to be fully rotated even when the equipment moves at a slow speed, thus enabling the cleaning of crevices.

[0010] Furthermore, the cleaning assembly includes a telescopic shell fixedly installed on the surface of the cleaning cylinder, and the surface of the telescopic shell is provided with a cleaning brush. A multi-layer filter plate is snapped onto the lower side of the inner wall of the connecting shell, and a connecting hose is fixedly installed on one side of the multi-layer filter plate on the connecting shell. A perforated air outlet shell is fixedly installed at one end of the connecting hose. By utilizing the multi-layer filter plate, dust can be filtered, so that the blown air will not contain dust or other pollutants. Moreover, the multi-layer filter plate is snapped on, so that the multi-layer filter plate can be removed for cleaning, and the filtered impurities can be centrally processed.

[0011] Furthermore, three push plates are slidably installed within the inner wall of the telescopic shell, with one end of each push plate extending through to the surface of the telescopic shell. The surfaces of the three push plates are all fixedly connected to the surface of the cleaning brush, and the other end of each push plate is fixedly installed with a tension spring along with the inner wall of the telescopic shell.

[0012] Furthermore, the storage assembly includes a storage cylinder fixedly installed inside the protective shell on one side, and a manual stirrer is provided on the top surface of the storage cylinder, and a liquid outlet cylinder is fixedly installed on one side of the cylinder wall.

[0013] Furthermore, the surface of the liquid outlet cylinder extends through to the surface of the protective shell, and a movable groove plate is fixedly installed on one side of the protective shell located on the liquid outlet cylinder. A starter valve plate is movably installed on the surface of the movable groove plate, and a starter wrench is rotatably installed on the surface of the starter valve plate. A guide groove is fixedly installed on the surface of the protective shell located below the movable groove plate.

[0014] Furthermore, inclined push plates are fixedly installed on both the front and rear sides of the protective shell, away from the front wheel frame, and a push handle is fixedly installed on the top surface of the two inclined push plates.

[0015] Furthermore, the dust extraction cylinder is arranged radially on the side of the cleaning brush, and the bottom opening of the dust extraction cylinder is an inclined structure, with the inclined direction of the inclined opening facing the working end of the brush bristles.

[0016] Furthermore, the axial length of the porous air outlet shell is not less than the vertical overlap height of the movable groove plate and the start valve plate, so as to ensure that the airflow ejected from the porous air outlet shell can fully cover the mating surface of the two plates.

[0017] Compared with the prior art, the present invention provides a road surface sealing adhesive device, which has the following beneficial effects:

[0018] 1. This equipment can clean the gaps again during the glue-filling process, and can also avoid the problem of secondary contamination of the glue by dust generated during cleaning. This equipment ensures the bonding strength between the road surface glue and the road surface gaps, and can also avoid increasing the cost of secondary processing.

[0019] 2. This equipment utilizes a planetary reducer to amplify the rotational speed of the output wheel. This allows the equipment to rotate at a high speed even when the moving speed is not fast, enabling the cleaning components to unfold and thus clean the crevices.

[0020] 3. This equipment utilizes a multi-layer filter plate setup to filter dust, ensuring that the blown gas is free of dust and other pollutants. Furthermore, the multi-layer filter plates are snap-fitted, allowing them to be removed for cleaning and the filtered impurities to be centrally processed.

[0021] 4. The device, through the design of the connecting hose and the hose structure, allows for adjustment of the position of the porous air outlet shell, better ensuring that the dispensing position is not affected by dust. Attached Figure Description

A conversion component 6 is provided on one side of the connecting shell 301, and output wheels 302 are provided on both the side of the conversion component 6 away from the protective shell 2 and the side of the connecting shell 301.

[0043] The conversion component 6 includes a fixed cylinder 601 embedded in one side of the surface of the connecting shell 301. A planetary reducer 602 is fixedly installed on the side of the fixed cylinder 601 away from the connecting shell 301. A power disk 603 is rotatably installed on the inner wall of the fixed cylinder 601. A cleaning cylinder 604 is rotatably installed on the surface of the planetary reducer 602 and the surface of the fixed cylinder 601. Several cleaning components 7 are equidistantly arranged on the outer peripheral wall of the cleaning cylinder 604 along its circumference. Each cleaning component 7 extends along the axial direction of the cleaning cylinder 604, and the angle between the central axis of two adjacent cleaning components 7 and the central axis of the cleaning cylinder 604 is equal.

[0044] An impeller 605 is fixedly installed on the side of the power disc 603 away from the planetary reducer 602. A dust extraction cylinder 606 is fixedly installed on the bottom surface of the fixed cylinder 601 away from the impeller 605. A U-shaped guide tube 607 is fixedly installed on the periphery of the impeller 605. Magnetic blocks 608 are embedded in the surface of the power disc 603 and the corresponding positions on the inner wall of the cleaning cylinder 604. The magnetic blocks 608 can use magnetic attraction to transmit the rotational power of the power disc 603 to the cleaning cylinder 604, ensuring the smooth operation of the cleaning assembly 7. The dust extraction cylinder 606 is arranged radially on the side of the cleaning brush 702. The bottom opening of the dust extraction cylinder 606 is an inclined structure, and the inclined direction of the inclined opening is towards the working end of the brush bristles of the cleaning brush 702.

[0045] In the planetary reducer 602, the planet carrier is fixedly connected to the surface of the fixed cylinder 601 and does not participate in rotation. The sun gear in the planetary reducer 602 serves as the output end and is fixedly connected to the surface of the power disk 603. The planet gear in the planetary reducer 602 serves as the input end and is fixedly connected to the surface of one of the output gears 302, and rotates around the fixed planet carrier axis.

The surfaces of the three push plates 7011 are fixedly connected to the surface of the cleaning brush 702. The other end of each push plate 7011 is fixedly installed with a tension spring 7012 together with the inner wall of the telescopic shell 701. The surface of the telescopic shell 701 is provided with the cleaning brush 702. A multi-layer filter plate 703 is snapped onto the lower side of the inner wall of the connecting shell 301. A connecting hose 704 is fixedly installed on one side of the connecting shell 301 and the multi-layer filter plate 703. A perforated air outlet shell 705 is fixedly installed at one end of the connecting hose 704. The axial length of the perforated air outlet shell 705 is not less than the vertical overlap height of the movable groove plate 5031 and the start valve plate 5032, so that the airflow ejected from the perforated air outlet shell 705 can fully cover the mating surface of the two plates.

[0047] The working principle of the above embodiments is as follows:

[0048] When the equipment is in use, the overall structure is supported by the fixed frame 1. The operator can drive the front wheel frame 3 and the caster wheel 4 on the bottom of the fixed frame 1 to roll synchronously by pushing the push handle 202 on the top surface of the inclined push plate 201. The caster wheel 4 can flexibly adjust the direction of the equipment to adapt to the direction of different road surface cracks. When the equipment moves to the area of ​​the crack to be repaired, the front wheel frame 3 starts the operation as the core power output end. The output wheel 302 of the front wheel frame 3 rotates during the movement or active driving of the equipment. Its rotational power is directly transmitted to the input end of the conversion component 6, providing the power basis for subsequent cleaning and dust collection processes.

[0049] The rotation of the output wheel 302 drives the input end of the planetary gears of the planetary reducer 602 to rotate. Since the planetary carrier of the planetary reducer 602 is fixedly connected to the surface of the fixed cylinder 601 and does not participate in the rotation, the planetary gears rotate around the axis of the fixed planetary carrier, while driving the output end of the sun gear to rotate. This, in turn, drives the power disk 603, which is fixedly connected to the sun gear, to rotate synchronously on the inner wall of the fixed cylinder 601. Here, since the planetary carrier is fixed, the entire mechanism degenerates into a fixed-axis external meshing gear pair composed of the sun gear and the planetary gears. In the external meshing transmission, the rotation directions of the two gears are opposite. Therefore, the rotation direction of the power disk 603 connected to the sun gear is always opposite to the rotation direction of the output wheel 302 connected to the planetary gears. Because the output wheel 302 is connected to the planetary gears, this can drive the power disk 603 on the sun gear to rotate quickly. This can achieve the effect that the rotation of one output wheel 302 drives the cleaning component 7 to rotate in the opposite direction quickly, thus ensuring that the dust will not be brushed backward during cleaning.

[0050] Meanwhile, the cleaning cylinder 604, supported by the planetary reducer 602 and the fixed cylinder 601, can rotate synchronously under the magnetic drive of the magnetic block 608. The cleaning components 7, which are equidistantly arranged in a circular array on the outer circumference of the cleaning cylinder 604, rotate synchronously with the cleaning cylinder 604, realizing the rotational cleaning of road surface cracks. The push plate 7011 is elastically supported by the tension spring 7012 inside the telescopic shell 701 of the cleaning component 7. The push plate 7011 drives the cleaning brush 702 to always be in contact with the surface of the road surface crack, which can adapt to the cleaning needs of cracks of different depths, ensuring that the working end of the brush bristles of the cleaning brush 702 fully contacts the crack and removes dust, scum and other impurities in the crack.

[0051] While cleaning component 7 is working, the impeller 605 on the side of the power disc 603 away from the planetary reducer 602 rotates synchronously at high speed with the power disc 603. The rotation of the impeller 605 generates negative pressure suction, and dust is collected through the dust collection cylinder 606 at the bottom of the fixed cylinder 601. Since the inclined opening at the bottom of the dust collection cylinder 606 faces the working end of the bristles of the cleaning brush 702, the dust stripped off by the cleaning brush 702 can be directly sucked in by the inclined opening, avoiding dust diffusion.

[0052] The U-shaped guide tube 607 around the impeller 605 guides the negative pressure airflow and dust into the connecting shell 301. The multi-layer filter plate 703 on the lower side of the inner wall of the connecting shell 301 filters the dust-laden airflow. The dust is intercepted on the multi-layer filter plate 703. The filtered clean airflow is delivered to the porous air outlet shell 705 through the connecting hose 704. When the air is discharged through the porous air outlet shell 705, an air wall is generated at the position of the movable slot plate 5031 and the start valve plate 5032, which further avoids the problem of secondary pollution of the dispensing position by dust and impurities.

[0053] Storage component 5 provides adhesive storage and output control for potting operations. The potting adhesive in storage cylinder 501 can be stirred evenly by manual mixer 502 to avoid adhesive sedimentation. The potting adhesive is output through the outlet cylinder 503 on one side of storage cylinder 501. The outlet cylinder 503 extends to the surface of protective shell 2 and forms a potting control structure with movable trough plate 5031 and start valve plate 5032. By turning the start wrench 5033, the operator can drive the start valve plate 5032 to move on the surface of movable trough plate 5031 to realize the on / off control of outlet cylinder 503 and adjust the output flow of potting adhesive.

[0054] Since the axial length of the porous air outlet shell 705 is not less than the vertical overlap height of the movable groove plate 5031 and the start valve plate 5032, the airflow it sprays can fully cover the mating surface of the two plates. The airflow can pre-purge the outlet of the liquid cylinder 503 and the crack area to be filled, further improving the bonding effect between the potting adhesive and the crack wall.

[0055] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
