Description

Technical Field

[0001] This invention relates to the field of leveling devices, and more particularly to an asphalt paving and leveling device for municipal road construction. Background Technology

[0002] Municipal roads refer to roads that connect various areas of a city, are used for transportation and pedestrians within the city, facilitate residents' lives, work, and cultural and recreational activities, and connect with roads outside the city to bear external transportation.

[0003] Asphalt paving equipment is machinery used to evenly spread asphalt mixture onto the road base. It comes in two types: tracked and wheeled. It consists of two main parts: traction and paving / compaction / screeding. The former includes the frame, power unit, traveling mechanism, hopper, material gate, scraper conveyor, auger paver, and driver's cab. The latter includes the traction boom, compaction mechanism, and screeding device (composed of a screed plate, thickness adjuster, camber adjuster, and heating device).

[0004] Existing asphalt paving devices typically involve dump trucks pouring asphalt into a fixed area, followed by asphalt spreading equipment and then compaction by a road roller. However, this method requires a large construction area and is unsuitable for municipal road construction. Furthermore, this method has high construction costs and low efficiency, which is detrimental to the repair and maintenance of urban roads. Therefore, designing an integrated asphalt paving and leveling device suitable for municipal roads is particularly important. In view of this, we propose an asphalt paving and leveling device for municipal road construction. Summary of the Invention

The paving mechanism includes a drive bracket, an asphalt baffle, a chain housing assembly, a mounting frame, a spiral paving rod, and a bucket. The drive bracket is located on the paver frame opposite to the power unit. The asphalt baffle is located at the bottom of the drive bracket. The chain housing assembly is located on the drive bracket opposite to the inner side of the asphalt baffle. The mounting frame is connected to the chain housing assembly. The spiral paving rod is connected to the chain housing assembly opposite to the mounting frame. The bucket is connected to the mounting frame opposite to the back of the spiral paving rod.

[0007] Preferably, the leveling mechanism includes a geared motor, a support frame, a reciprocating assembly, a rotating assembly, a leveling roller, and a sliding assembly. The support frame is connected to the paver frame at a position relative to the back of the drive support. The geared motor is connected to the support frame. The reciprocating assembly is connected to the support frame. The rotating assembly is connected to the support frame at a position relative to the reciprocating assembly. The sliding assembly is connected to the paver frame. One end of the leveling roller is connected to the rotating assembly, and the other end of the leveling roller is slidably inserted into the sliding assembly.

[0008] Preferably, the reciprocating assembly includes a drive shaft, a rotating arm, a connecting block, a slider, a moving block, and a slide groove. The drive shaft passes through the support frame at a position relative to the output end of the geared motor. The rotating arm is connected to the drive shaft. The connecting block is connected to the end of the rotating arm away from the drive shaft. The slider is connected to the connecting block. The moving block is slidably connected to the rotating assembly. The slide groove is formed on the moving block, and the slider is slidably connected to the slide groove.

[0009] Preferably, the rotating assembly includes a reciprocating frame, an elongated hole, a rotating block, a limiting groove, and a limiting block. The reciprocating frame is connected to the support frame, the elongated hole is formed on the reciprocating frame, the limiting groove is located on the back of the reciprocating frame opposite to the elongated hole, the rotating block is slidably connected to the elongated hole, the limiting block is slidably connected to the limiting groove, one end of the rotating block is connected to the limiting block, and the other end of the rotating block is connected to the leveling roller.

[0010] Preferably, a rack is provided on the reciprocating frame at a position relative to the bottom end of the elongated hole, a positioning rod is provided on the reciprocating frame at a position relative to both ends of the elongated hole, a half gear is provided on one side of the rotating block, and a positioning block is provided on the other side of the rotating block.

[0011] Preferably, the half gear meshes with the rack for transmission, and the positioning rod is sized to match the positioning block.

[0012] Preferably, the sliding assembly includes a slide frame, a sliding hole, and a buffer spring. The slide frame is connected to the paver frame at a position relative to the bottom end of the drive support. The sliding hole is opened on the slide frame. The buffer spring is located at both ends of the sliding hole. The end of the paving roller away from the support frame is slidably inserted into the sliding hole.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention improves the structure of existing asphalt paving and leveling devices for municipal road construction. By setting a paving mechanism on the paver frame, a power unit connects the drive support, chain housing, and auger paving rod of the paving mechanism. The rotating auger paving rod evenly spreads the asphalt mixture unloaded from the dump truck along the paving width. After the asphalt mixture is laid by the paving mechanism, a leveling mechanism performs preliminary smoothing. The reduction motor of the leveling mechanism drives the leveling roller to smooth the paved asphalt mixture. This invention optimizes the problem that existing municipal road construction areas and areas are too small for construction, thus reducing construction costs and improving construction efficiency.

[0014] 2. This invention provides a support frame positioned on the back of the paver frame relative to the drive support, with a reduction motor mounted on the support frame. The reduction motor drives the reciprocating assembly to rotate, which in turn drives the rotating assembly to move. The rotating assembly then drives the leveling roller to slide on the sliding assembly, thus leveling the asphalt mixture laid by the paving mechanism. This eliminates the need for compaction by a road roller during subsequent construction, shortening the construction cycle, reducing construction costs, and benefiting the construction and repair of municipal roads.

[0015] 3. This invention provides a reciprocating frame on the support frame, with a limiting groove on the back of the reciprocating frame. A limiting block is slidably connected to the limiting groove, and the limiting block is connected to a connecting block. The connecting block drives the limiting block and the rotating block to slide on the elongated hole. The rotating block causes the leveling roller to rotate during the reciprocating leveling process, further optimizing the leveling effect and preventing the leveling effect of the leveling roller from decreasing under long-term operation, thereby improving the construction quality of the device.

[0016] 4. This invention features a rack on the reciprocating frame at the bottom of the long hole, positioning rods at both ends of the long hole, a half-gear on one side of the rotating block, and a positioning block on the other side. When the rotating block reciprocates, the half-gear meshes with the rack, causing the rotating block to rotate. The positioning block on the rotating block is matched with the positioning rod, preventing the rotating block from not rotating. This helps to optimize the operation of the device and reduce the failure rate. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: An asphalt paving and leveling device for municipal road construction, see [link / reference] Figures 1 to 8 The system includes a paver frame 1, a traveling mechanism 2 at the bottom of the paver frame 1, a traveling frame 3 at the back of the paver frame 1, a driver's control room 4 on the paver frame 1 opposite to the traveling frame 3, a power unit 5 on the paver frame 1 opposite to the driver's control room 4, a paving mechanism 6 on the front of the paver frame 1, and a leveling mechanism 7 on the paver frame 1 opposite to the paving mechanism 6. The paving mechanism 6 includes a drive bracket 601, an asphalt baffle 602, a chain housing 603, a mounting frame 604, and a spiral paving mechanism. The paver is equipped with a rod 605 and a bucket 606. The drive bracket 601 is located on the paver frame 1 relative to the power unit 5. The asphalt baffle 602 is located at the bottom of the drive bracket 601. The chain housing 603 is located on the drive bracket 601 relative to the inner side of the asphalt baffle 602. The mounting frame 604 is connected to the chain housing 603. The auger paving rod 605 is connected to the chain housing 603 relative to the mounting frame 604. The bucket 606 is connected to the mounting frame 604 relative to the back of the auger paving rod 605. This invention improves the structure of existing asphalt paving and leveling devices for municipal road construction. By setting a paving mechanism 6 on the paver frame 1, and connecting the drive support 601, chain housing 603, and spiral paving rod 605 of the paving mechanism 6 through a power unit 5, the spiral paving rod 605 rotates to evenly spread the asphalt mixture unloaded from the dump truck along the paving width. After the asphalt mixture is laid by the paving mechanism 6, it is initially smoothed by the leveling mechanism 7. The reduction motor 701 of the leveling mechanism 7 drives the leveling roller 705 to smooth the paved asphalt mixture. This invention optimizes the problem that existing municipal road construction areas and construction areas are small and unsuitable for construction, which helps to reduce construction costs and improve construction efficiency.

[0019] Specifically, the leveling mechanism 7 includes a geared motor 701, a support frame 702, a reciprocating assembly 703, a rotating assembly 704, a leveling roller 705, and a sliding assembly 706. The support frame 702 is connected to the paver frame 1 at a position relative to the back of the drive support 601. The geared motor 701 is connected to the support frame 702. The reciprocating assembly 703 is connected to the support frame 702. The rotating assembly 704 is connected to the support frame 702 at a position relative to the reciprocating assembly 703. The sliding assembly 706 is connected to the paver frame 1. One end of the leveling roller 705 is connected to the rotating assembly 704, and the other end of the leveling roller 705 is slidably inserted into the sliding assembly 706. This invention provides a support frame 702 positioned on the back of the paver frame 1 relative to the drive support 601. A reduction motor 701 is mounted on the support frame 702, driving the reduction motor 701 to rotate the reciprocating assembly 703. The reciprocating assembly 703 then drives the rotating assembly 704, which in turn drives the leveling roller 705 to slide on the sliding assembly 706. This process levels the asphalt mixture laid by the paving mechanism 6, eliminating the need for compaction by a road roller in subsequent construction. This shortens the construction cycle, reduces construction costs, and is beneficial for the construction and repair of municipal roads.

[0020] Furthermore, the reciprocating assembly 703 includes a drive shaft 7031, a rotating arm 7032, a connecting block 7033, a slider 7034, a moving block 7035, and a slide groove 7036. The drive shaft 7031 passes through the support frame 702 at a position relative to the output end of the reduction motor 701. The rotating arm 7032 is connected to the drive shaft 7031. The connecting block 7033 is connected to the end of the rotating arm 7032 away from the drive shaft 7031. The slider 7034 is connected to the connecting block 7033. The moving block 7035 is slidably connected to the rotating assembly 704. The slide groove 7036 is formed on the moving block 7035. The slider 7034 is slidably connected to the slide groove 7036. The present invention provides a speed reduction motor 701 on the support frame 702. The speed reduction motor 701 drives the transmission shaft 7031 to rotate, the transmission shaft 7031 drives the rotating arm 7032 to rotate, the rotating arm 7032 drives the connecting block 7033 to rotate, and the connecting block 7033 drives the slider 7034 to slide on the slide groove 7036 of the moving block 7035. This allows the rotating component 704 to achieve a reciprocating scraping effect, which helps to save subsequent secondary processing and improves work efficiency.

[0021] Furthermore, the rotating assembly 704 includes a reciprocating frame 7041, an elongated hole 7042, a rotating block 7043, a limiting groove 7044, and a limiting block 7045. The reciprocating frame 7041 is connected to the support frame 702. The elongated hole 7042 is formed on the reciprocating frame 7041. The limiting groove 7044 is located on the back of the reciprocating frame 7041 opposite to the elongated hole 7042. The rotating block 7043 is slidably connected to the elongated hole 7042. The limiting block 7045 is slidably connected to the limiting groove 7044. One end of the rotating block 7043 is connected to the limiting block 7045, and the other end of the rotating block 7043 is connected to the leveling roller 705. This invention provides a reciprocating frame 7041 on a support frame 702. The back of the reciprocating frame 7041 has a limiting groove 7044, and a limiting block 7045 is slidably connected to the limiting groove 7044. The limiting block 7045 is connected to a connecting block 7033. The connecting block 7033 drives the limiting block 7045 and the rotating block 7043 to slide on the elongated hole 7042. The rotating block 7043 causes the leveling roller 705 to rotate during the reciprocating leveling process, further optimizing the leveling effect and preventing the leveling effect of the leveling roller 705 from decreasing under long-term operation, thereby improving the construction quality of the device.

[0022] It is worth noting that a rack 7046 is provided on the reciprocating frame 7041 at the position opposite to the bottom of the long hole 7042, and a positioning rod 7047 is provided on both ends of the reciprocating frame 7041 opposite to the long hole 7042. A half gear 7048 is provided on one side of the rotating block 7043, and a positioning block 7049 is provided on the other side of the rotating block 7043. This invention features a rack 7046 positioned on the reciprocating frame 7041 relative to the bottom of the elongated hole 7042, and positioning rods 7047 positioned at both ends of the elongated hole 7042. A half-gear 7048 is provided on one side of the rotating block 7043, and a positioning block 7049 is provided on the other side. When the rotating block 7043 reciprocates, the half-gear 7048 meshes with the rack 7046, causing the rotating block 7043 to rotate. The positioning block 7049 on the rotating block 7043 is adapted to the positioning rods 7047, preventing the rotating block 7043 from not rotating. This optimizes the device's operating performance and reduces the failure rate.

[0023] It is worth noting that the half gear 7048 meshes with the rack 7046 for transmission, and the positioning rod 7047 is sized to match the positioning block 7049. This invention uses the meshing of the half gear 7048 and the rack 7046 to rotate the rotating block 7043. The positioning block 7049 on the rotating block 7043 matches the positioning rod 7047, preventing the rotating block 7043 from not rotating. The reciprocating flattening combined with the rotational effect significantly improves the flattening effect, thus increasing efficiency.

[0024] It is worth noting that the sliding assembly 706 includes a slide 7061, a sliding hole 7062, and a buffer spring 7063. The slide 7061 is connected to the paver frame 1 at a position relative to the bottom of the drive support 601. The sliding hole 7062 is formed on the slide 7061, and the buffer spring 7063 is located at both ends of the sliding hole 7062. The end of the paving roller 705 away from the support frame 702 is slidably inserted into the sliding hole 7062. This invention, by setting the slide 7061 at a position relative to the bottom of the drive support 601 on the paver frame 1, and providing the sliding hole 7062 on the slide 7061 with the buffer spring 7063 at both ends of the sliding hole 7062, allows the buffer spring 7063 to buffer the paving roller 705 during its reciprocating rotation, preventing collisions caused by tooth contact, enhancing the stability of the device, and extending its service life.

[0025] Working Principle: In use, this invention first establishes a paving mechanism 6 on the paver frame 1. A power unit 5 connects the paving mechanism 6 to a drive bracket 601, a chain housing 603, and a spiral paving rod 605. The spiral paving rod 605 rotates to evenly spread the asphalt mixture unloaded from the dump truck along the paving width. After the asphalt mixture is laid by the paving mechanism 6, a support frame 702 is positioned on the paver frame 1 relative to the back of the drive bracket 601. A reduction motor 701 is mounted on the support frame 702, driving the reduction motor 701 to rotate the reciprocating assembly 703. The reciprocating assembly 703 then drives the rotating assembly 704, which in turn causes the leveling roller 705 to slide on the sliding assembly 706. The reduction motor 701 drives the transmission shaft 7031 to rotate, which in turn drives the rotating arm 7032 to rotate. The rotating arm 7032 then drives the connecting block 7033 to rotate, and the connecting block 7033 then drives the slider 703. 4. The moving block 7035 slides on the groove 7036. A reciprocating frame 7041 is provided on the support frame 702. A limit groove 7044 is provided on the back of the reciprocating frame 7041. A limit block 7045 is slidably connected to the limit groove 7044. The limit block 7045 is connected to the connecting block 7033. The connecting block 7033 drives the limit block 7045 and the rotating block 7043 to slide on the elongated hole 7042. The rotating block 7043 causes the leveling roller 705 to reciprocate and scrape flat during the process. Rotation occurs in the middle. Positioning rods 7047 are provided at both ends of the elongated hole 7042. A half gear 7048 is provided on one side of the rotating block 7043, and a positioning block 7049 is provided on the other side of the rotating block 7043. When the rotating block 7043 reciprocates, the half gear 7048 meshes with the rack 7046, causing the rotating block 7043 to rotate. The positioning block 7049 on the rotating block 7043 is adapted to the positioning rod 7047 to prevent the rotating block 7043 from not rotating.
