Description

Technical Field

[0001] The invention belongs to the technical field of road paving, and in particular relates to an asphalt paver for road paving. Background Art

[0002] Asphalt paver is a kind of construction equipment mainly used for paving various materials on the base and surface layers of highways. The operation process of the paver is firstly that the dump truck unloads the mixture into the hopper of the paver. In the process of asphalt pavement construction, it is often necessary to use the asphalt paver to evenly spread the asphalt mixture on the road base, and then carry out preliminary vibration and leveling to ensure the quality and service life of the asphalt pavement.

[0003] In the prior art, there is a vibrating device for an asphalt paver with publication number CN116024871A, which includes a bracket, a crankshaft, a movable rod and a shock absorber; pillars are fixedly welded at both ends of the bracket, a crankshaft is movably installed on the inner side above the pillar, and a motor is fixedly installed on the outer side of the pillar through a motor frame; a sleeve is installed longitudinally through the bracket, a movable rod is movably installed longitudinally in the sleeve, a movable arm is movably installed on the top of the movable rod through a rotating shaft, a sleeve is fixedly welded on the top of the movable arm, and the sleeve is movably sleeved on the crankshaft. The motor drives the crankshaft to rotate and drive multiple groups of movable arms to rise and fall simultaneously, so that multiple groups of movable rods can simultaneously drive the compacting plate to move up and down to achieve compaction work, and the compacting plate is subjected to more uniform force, so that the compaction stability and quality are higher, and it can effectively prevent the situation where the uneven force on the compacting plate causes a difference in pressure on one side.

[0004] In order to solve the problem of the complex overall structure of the existing asphalt paver compaction device, the existing technology uses a compaction plate that moves up and down to compact the asphalt.

[0005] However, in actual use, when the asphalt is transported to the paving site, it is easy for the asphalt to be concentrated in the center in front of the vehicle. This can easily cause uneven thickness in some areas when the asphalt is compacted, and it does not have the function of auxiliary leveling of the asphalt, which affects the asphalt paving effect and work efficiency on the road surface.

[0006] Therefore, we proposed an asphalt paver for road paving to solve the problem that the uneven thickness of asphalt paving on the existing road surface affects the paving effect. It can achieve the effect of compacting and leveling the asphalt, thereby enhancing the asphalt paving effect. Summary of the invention

The optimized design of the spiral of the spiral stirring plate 33 can ensure that the asphalt is evenly spread within the range of the turning chute 21, and the asphalt will not accumulate in one position. At this time, the motor 31 is driven, and its output shaft simultaneously drives the driving pulley 311 to rotate. Through the rotation of the belt, the driven pulley 312 rotates synchronously, and the center rod 313 rotates at this time.

[0042] Embodiment 3, refer to the attached Figure 1-18, on the basis of the second embodiment, in order to achieve the reciprocating movement of the ironing strip 442 longitudinally and ensure the intermittent ramming of the asphalt: the moving assembly 42 includes a connecting circular plate 421, the inner surface of the connecting circular plate 421 is fixedly connected to the outer surface of one end of the central rod 313, a limiting convex column 422 is fixedly connected to the outer side surface of the connecting circular plate 421, the limiting convex column 422 is eccentrically arranged with respect to the central axis of the connecting circular plate 421, the剖切 cross-section of the limiting convex column 422 is in a "T" - shaped structure, a first movable arm rod 423 is rotatably connected to the outer surface of the limiting convex column 422, a second movable arm rod 424 is rotatably installed at the other end of the first movable arm rod 423, and a pin rod 425 is rotatably connected to the end of the second movable arm rod 424 away from the first movable arm rod 423, a limiting connection slider 426 is fixedly connected to the other end of the pin rod 425, the outer surface of the limiting connection slider 426 is slidably connected to the inner wall of the lifting groove 411, there are two groups of limiting connection sliders 426, the inner side surfaces of the two groups of limiting connection sliders 426 are respectively fixedly connected to both ends of the lifting cover plate 43, the lifting cover plate 43 is in an overall "冂" - shaped plate structure, a limiting cross bar 431 is fixedly installed on the inner side surface of the lifting cover plate 43, and a supporting wing block 432 is fixedly added to the inner side of the lower end of the lifting cover plate 43, a strip - shaped sliding sleeve rod 44 is slidably connected to the outer surface of the limiting cross bar 431, a connecting support plate 441 is fixedly connected to the lower end of the strip - shaped sliding sleeve rod 44, an ironing strip 442 is fixedly connected to the lower surface of the connecting support plate 441, a material - leveling rake plate 443 is fixedly added to the lower side outer surface of the ironing strip 442, there are multiple groups of material - leveling rake plates 443, and the multiple groups of material - leveling rake plates 443 are horizontally and equidistantly arranged in an arc - shaped plate structure on the lower side outer surface of the ironing strip 442, a high - temperature resistant buffer block 4431 is fixedly added to the lower side outer surface of the material - leveling rake plate 443; in this embodiment, under the linkage rotation of the driven belt pulley 312 and the driving belt pulley 311, the central rod 313 rotates and drives the connecting circular plate 421 to rotate. At this time, the first movable arm rod 423 and the second movable arm rod 424 move under the eccentric rotation of the limiting convex column 422, and then drive the limiting connection slider 426 connected to one end of the pin rod 425 to perform longitudinal reciprocating lifting inside the lifting groove 411. And at this time, the lifting cover plate 43 connected to the inner side of the limiting connection slider 426 rises and falls synchronously with the movement of the limiting connection slider 426. The limiting cross bar 431 connected to the inner side of the lifting cover plate 43 serves as a limiting member for the strip - shaped sliding sleeve rod 44. When the lifting cover plate 43 performs reciprocating lifting movement, the strip - shaped sliding sleeve rod 44 and the connecting support plate 441 and the ironing strip 442 connected to its lower end move synchronously. Thus, the material - leveling rake plate 443 can hammer the road asphalt up and down, and can ram and iron the road asphalt to ensure the balance of the extrusion force.

[0043] Embodiment 4, referring to the attached Figure 1-18On the basis of the third embodiment, in order to realize the horizontal reciprocating movement of the material leveling rake plate 443 and ensure the horizontal even spreading of the asphalt: a convex plate 433 is fixedly provided on the outer surface of one side of the lifting cover plate 43, and a horizontal reciprocating drive assembly 45 is arranged on the convex plate 433. The horizontal reciprocating drive assembly 45 includes a driving motor 451, and the driving motor 451 is fixedly mounted on the outer surface of one side of the convex plate 433.

The inner side of the rotating disc 452 A limiting round rod 453 is fixedly installed on the outer surface, and the outer surface of the limiting round rod 453 is movably connected with an annular swing rod 454. A movable groove 4541 is opened on the inner wall of the annular swing rod 454, and the inner surface of the movable groove 4541 is movably connected with the outer surface of the limiting round rod 453. A fan-shaped swing plate 455 is fixedly installed on the lower end of the annular swing rod 454. The lower outer surface of the fan-shaped swing plate 455 is meshed and rotated with a strip-shaped meshing plate 456. The outer surfaces of both ends of the strip-shaped meshing plate 456 are respectively fixedly connected to the inner wall of the connecting support plate 441, and the two ends of the strip-shaped meshing plate 456 are respectively fixedly installed with fixed clamps The seat 4561 is provided with two groups of fixed seats 4561, and the two groups of fixed seats 4561 are fixedly mounted on the outer surface of the connecting support plate 441; in this embodiment, when the material leveling rake plate 443 is reciprocatingly lifted and lowered, when the asphalt surface needs to be evenly spread, the control driving motor 451 is turned on, and its output shaft rotates as the hub of power transmission, so that the rotating disk 452 rotates, and the eccentric setting of the limiting rod 453 causes the limiting rod 453 to rotate in a circle under the rotation of the rotating disk 452. At this time, the annular swing rod 454 outside the limiting rod 453 moves along with the movement of the limiting rod 453. The strip meshing plate 456 is fixed to the connecting support plate 441, thereby realizing the horizontal movement of the strip sliding sleeve 44 and the connecting support plate 441 as a whole. At this time, the strip sliding sleeve 44 is horizontally limited by the limiting cross bar 431. In this way, the material leveling rake plate 443 will spread the asphalt on the road surface left and right to ensure that the road asphalt is evenly spread. At the same time, it can ensure the looseness of the asphalt, which is convenient for the subsequent compaction operation of the tamping vehicle.

[0044] Embodiment 5, refer to the attached Figure 1-18On the basis of the fourth embodiment, in order to realize that the strip sliding sleeve rod 44 assists in driving the air flow in the hollow air collecting storage plate 53 to dry the road asphalt when moving left and right: elastic impact rods 5 are fixedly installed on the outer surfaces of both ends of the strip sliding sleeve rod 44, and a telescopic air bag 51 is arranged on the outer side of the elastic impact rod 5. The telescopic air bag 51 is arranged on the inner surface of the lifting cover plate 43, and the telescopic air bag 51 is arranged on the inner side of the supporting wing block 432. The outer surface of the elastic impact rod 5 is movably abutted against the outer surface of the telescopic air bag 51, and the upper end of the telescopic air bag 51 is connected with an air guide pipe 52, and the output end of the air guide pipe 52 is fixedly connected with the hollow air collecting storage plate 53, and the upper surface of the hollow air collecting storage plate 53 is fixedly connected with a fixing part, and the fixing part is fixedly connected with the outer surface of the hollow air collecting storage plate 53, and the inner side of the hollow air collecting storage plate 53 is provided with an electric heating wire, and the lower surface of the hollow air collecting storage plate 53 is arranged as an inclined surface, and an exhaust port 5 is opened on the inner wall of the inclined surface. 31; In the present embodiment, when the strip sliding sleeve 44 is in the process of horizontal movement, the elastic impact rods 5 connected at both ends of the strip sliding sleeve 44 will intermittently squeeze the telescopic airbag 51 arranged on the side. At this time, the telescopic airbag 51 is compressed by the external squeezing, so that the gas inside the telescopic airbag 51 enters the hollow air collecting storage plate 53 through the air guide tube 52. The airflow entering the hollow air collecting storage plate 53 is assisted by the heating wire to increase the temperature. Then, the hot air inside the hollow air collecting storage plate 53 is continuously sprayed toward the road surface through the exhaust port 531 again, thereby achieving the drying of the asphalt, reducing the moisture in the asphalt, and improving the drying efficiency of the asphalt. Through such a setting, multiple effects can be achieved by one kinetic energy, further solving the problem that the uneven thickness of asphalt paving on the existing road surface affects the paving effect, and can achieve the effect of compacting and leveling the asphalt, thereby enhancing the asphalt paving effect.

[0045] The working principle and use process of the present invention are as follows: in actual operation, first, the operator drives the main body 1 of the paver to travel on the road surface. Before traveling, the hopper 12 connected to one end of the main body 1 of the paver is connected to the asphalt loading truck. Then the main body 1 of the paver moves slowly in the direction of the truck. The asphalt entering the hopper 12 is continuously conveyed by the conveying component 13 and enters the inside of the turning trough 21 through the feeding port 20. At this time, the driving motor 31 is turned on to provide power output for the rotation of the connecting shaft 32. Then the spiral stirring plate 33 rotates continuously to continuously stir the asphalt in the inner cavity of the turning trough 21. The optimized design of the spiral of the spiral stirring plate 33 can ensure that the asphalt is evenly distributed within the range of the turning trough 21. The asphalt is evenly spread out, and there will be no situation where asphalt accumulates in one position; furthermore, when the motor 31 is driven, its output shaft simultaneously drives the driving pulley 311 to rotate, and through the rotation of the belt, the driven pulley 312 rotates synchronously, and at this time the center rod 313 rotates; at this time, under the linkage rotation of the driven pulley 312 and the driving pulley 311, the center rod 313 rotates and drives the connecting circular plate 421 to rotate, and at this time the movable arm rod 1 423 and the movable arm rod 2 424 move under the eccentric rotation of the limiting convex column 422, and then drive the limiting connecting slider 426 connected to one end of the pin rod 425 to perform longitudinal reciprocating lifting and lowering on the inner side of the lifting groove 411, and at this time the limiting connecting slider 426 The lifting cover plate 43 connected on the inner side is lifted and lowered synchronously with the movement of the limit connecting slider 426. The limit cross bar 431 connected on the inner side of the lifting cover plate 43 serves as a limit piece of the strip sliding sleeve rod 44. When the lifting cover plate 43 is reciprocatingly lifted and lowered, the strip sliding sleeve rod 44 and the connecting support plate 441 and the ironing strip plate 442 connected to its lower end are moved synchronously, thereby realizing the up and down hammering of the road asphalt by the leveling rake plate 443. In addition, when the leveling rake plate 443 is reciprocatingly lifted and lowered and the asphalt surface needs to be evenly spread, the control driving motor 451 is turned on, and the rotation of its output shaft serves as the hub of power transmission, so that the rotating disc 452 rotates, and the eccentric setting of the limit round rod 453, Under the rotation action of the rotating disc 452, the limiting rod 453 rotates in a circle. At this time, the annular swing rod 454 outside the limiting rod 453 swings left and right with the movement of the limiting rod 453, and the lower outer surface of the fan-shaped swing plate 455 is meshed with the surface of the strip meshing plate 456, thereby realizing the horizontal movement of the strip meshing plate 456. The strip meshing plate 456 is fixed to the connecting support plate 441, thereby realizing the horizontal movement of the strip sliding sleeve rod 44 and the connecting support plate 441 as a whole, and at this time, the strip sliding sleeve rod 44 is horizontally limited by the limiting cross bar 431. In this way, the material leveling rake plate 443 will spread the asphalt on the road surface left and right to ensure that the road asphalt is evenly spread.
