Description

Technical Field

[0001] This invention relates to a road paving equipment and paving method for engineering construction, belonging to the technical field of asphalt road paving equipment. Background Technology

[0002] A paver is a construction equipment mainly used for paving various materials for the base and surface layers of highways.

[0003] Existing pavers perform a one-time leveling and paving operation on the discharged asphalt material. During the paving operation, the asphalt material is sometimes unevenly distributed, resulting in small unevenness on the road surface in areas where asphalt material is missing after leveling and paving. These areas need to be manually filled in during subsequent inspections, which is time-consuming and labor-intensive. To address the above shortcomings, this invention proposes a road paving equipment and paving method for engineering construction. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a road paving equipment and paving method for engineering construction, so as to solve the existing problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a road paving equipment for engineering construction, the structure of which includes a frame assembly, wherein a hopper assembly for pouring asphalt raw materials is longitudinally arranged on the left side of the top surface of the frame assembly, and a paving mechanism is mounted on the bottom right side of the frame assembly with a lifting mechanism, the other end of which extends into the upper end of the hopper assembly; a compaction roller body is installed at the right rear of the frame assembly; a lifting front wheel is installed at the left rear of the frame assembly; a level sensor is horizontally arranged on the front side of the frame assembly; and a control box electrically connected to the hopper assembly, the paving mechanism, the compaction roller body, the lifting front wheel, and the level sensor is also arranged on the front side of the frame assembly.

[0006] The paving mechanism includes a paving and leveling seat assembly, and multiple lifting sliding columns for fixing to the front and rear sides of the frame assembly are vertically arranged on the four sides of the top surface of the paving and leveling seat assembly. Each lifting sliding column is connected to a first hydraulic cylinder on its top surface. A conveyor belt is inclinedly arranged on the right side of the top surface of the paving and leveling seat assembly, and a guide hopper assembly is arranged below the right side of the conveyor belt.

[0007] The paving and leveling seat assembly includes a push seat body, and a leveling guide plate is connected to the left rear of the push seat body. A compensation aggregate plate is aligned with the right side of the leveling guide plate. A guide partition is obliquely arranged above the leveling guide plate and the compensation aggregate plate. A crossbeam for placing the guide hopper assembly is arranged horizontally on the right side of the push seat body. The bottom surfaces of the push seat body, the leveling guide plate, and the compensation aggregate plate are horizontally aligned.

[0008] Further improvements include a hopper cavity and a material pipe opening on the left side of the frame assembly; multiple openings for lifting and lowering the sliding column assembly are spaced apart on the front and rear sides of the frame assembly; an opening for preventing jamming after the paving and leveling seat assembly rises is provided on the right side of the frame assembly; a lifting slide for vertical sliding of the front wheels is provided on the bottom left side of the frame assembly; and a traction head is provided laterally on the left side of the frame assembly.

[0009] A further improvement is that the hopper assembly includes a hopper box, and the bottom surface of the hopper box is provided with a shock-absorbing pad. A discharge square tube is connected to the middle of the bottom surface of the hopper box, and a draw plate valve is connected to the discharge square tube. Multiple vibrators are provided on the front and rear sides of the hopper box. A flow diffuser is connected to the lower end of the discharge square tube. The shock-absorbing pad is made of rubber.

[0010] The diffuser nozzle is trapezoidal in shape, and its width is wider at the top and narrower at the bottom. Multiple flow dividers are irregularly arranged inside the diffuser nozzle cavity.

[0011] A further improvement is that a compensation guide chamber is provided through the top left side of the pusher body, and a compensation collection chamber is formed by the partition between the left side wall of the compensation guide chamber and the guide partition. The left side of the compensation collection chamber is provided with a feeding channel for leveling the guide plate assembly and guiding the material to the right.

[0012] A further improvement is that, after the top surface of the compensation collecting plate and the bottom surface of the guide partition are fitted together in the compensation guiding chamber, they form a collecting channel that guides material to the right onto the conveyor belt.

[0013] The right side of the compensation aggregate plate and the right wall of the compensation guide chamber form a conveyor belt sleeve cavity for the lower end of the conveyor belt to extend downward and be fitted. The bottom surface of the conveyor belt sleeve cavity is provided with a slag discharge hole.

[0014] A further improvement is that the leveling guide plate is composed of a first inclined push plate and a first push head assembly. Multiple staggered guide baffles are arranged obliquely at intervals on the inclined surface of the leveling guide plate, and the first push head is made of high-strength steel.

[0015] A further improvement is that the compensation aggregate plate is composed of a second inclined push plate and a second push head assembly. The top surface of the compensation aggregate plate is symmetrically and inclinedly provided with two flow-collecting side plates that form the side walls required for the flow-collecting channel. The second push head is made of high-strength steel.

[0016] A further improvement is that the guide hopper assembly includes a collection hopper, the bottom of which is connected to an asphalt pump, and a flexible scraper is obliquely arranged in the cavity on the top surface of the collection hopper. The upper end of the flexible scraper flexibly abuts against the bottom surface of the conveyor belt. The discharge end of the asphalt pump is connected to a discharge hose and a discharge fixing pipe, and the discharge fixing pipe extends and is fixedly installed on the hopper box.

[0017] A further improvement is that the lifting front wheel is assembled from a lifting slide block, a second hydraulic cylinder, a front wheel shock absorber, and a front wheel, with the lifting slide block fitted inside the lifting track.

[0018] Further improvements are made to the fact that the compaction roller body, level sensor, control box, lifting slide column, pull plate valve, vibrator, conveyor belt, and asphalt pump are all existing technologies, and their structures will not be described in detail here.

[0019] A further improvement is that a tractor is externally connected to the tractor head, and the device is electrically connected to the tractor.

[0020] A further improvement is that the conveyor belt is equipped with a side leakage prevention plate.

[0021] Furthermore, the present invention also provides a paving method for the road paving equipment mentioned above in engineering construction: the paving method is as follows:

[0022] During asphalt pavement construction, an external tractor is used to drive the equipment. Then, the valve is opened to allow the asphalt material to flow from the expansion nozzle onto the roadbed. At this time, the asphalt material on the roadbed will be irregular and uneven, requiring leveling and paving by the paving mechanism.

[0023] Then, the paving mechanism is lowered, and the height between the bottom surface of the paving mechanism and the roadbed surface is adjusted to limit the thickness of the asphalt pavement. When the paving mechanism spreads the asphalt raw material from right to left, it is initially leveled by the leveling guide plate. However, at this time, due to the uneven distribution of the asphalt raw material, there will still be some unevenness caused by material shortage. Then, the compensation aggregate plate is used to compensate for the unevenness caused by material shortage and fill it, and then the paving is leveled again. Then, the excess asphalt raw material is pushed to the right onto the conveyor belt and transported to the guide hopper group. Then, the guide hopper group returns the excess asphalt raw material to the hopper box.

[0024] Finally, when the compaction roller body moves to the left, it will roll and compact the asphalt road surface that has been laid and leveled on the left. When the compaction roller body rolls onto the asphalt road surface, the frame assembly will tilt slightly to the left. It is necessary to adjust the frame assembly to a horizontal state by raising the front wheel and coordinating with the sensing of the level sensor before continuing the paving operation to the left.

[0025] The beneficial effects of this invention are:

[0026] This invention provides a road paving device and method for engineering construction. The paving mechanism, consisting of a paving and leveling base assembly, a lifting sliding column, a first hydraulic cylinder, a conveyor belt, and a guide hopper assembly, is combined with a hopper assembly, a compaction roller body, a lifting front wheel, a level sensor, and a control box on a frame assembly. This combination of components forms a road paving device for engineering construction. The paving mechanism has a lifting function to facilitate adjustment of the thickness of the asphalt pavement to be paved and leveled. The lifting front wheel, in conjunction with the level sensor, allows for horizontal adjustment of the frame assembly, preventing the paving mechanism from slipping. When paving, there is a tilting issue. The paving mechanism has a preliminary paving and leveling function. After the preliminary paving and leveling, the excess material is staggered and guided to the road surface in the horizontal position where there is a lack of material for automatic material addition and filling. Then, the excess material is collected and guided to the conveyor belt and discharged into the guide hopper group for final recycling. This paving equipment can automatically compensate and fill the slight unevenness of the road surface in the horizontal position, so that the road surface paved by this equipment is smooth and improves the construction quality of the road.

[0040] The top left side of the pusher body 311 is provided with a compensation guide chamber 3111, and the left side wall of the compensation guide chamber 3111 is partitioned with the guide partition 314 to form a compensation collection chamber 3112. The left side of the compensation collection chamber 3112 is provided with a feeding channel 3113 for leveling the guide plate 312 through the assembly and guiding the material to the right.

[0041] A further improvement is that, after the top surface of the compensating aggregate plate 313 and the bottom surface of the guiding partition 314 are fitted inside the compensating guiding chamber 3111, a flow channel 3114 is formed to guide material to the right onto the conveyor belt 34. A conveyor belt sleeve cavity 3115 is formed between the right side of the compensating aggregate plate 313 and the right chamber wall of the compensating guiding chamber 3111, which allows the lower end of the conveyor belt 34 to extend downwards and be fitted. A slag discharge hole 3116 is provided through the bottom surface of the conveyor belt sleeve cavity 3115.

[0042] The leveling guide plate 312 is composed of a first inclined push plate 3121 and a first push head 3123. Multiple staggered guide plates 3122 are obliquely spaced on the inclined surface of the leveling guide plate 312. The first push head 3123 is made of high-strength steel.

[0044] The guide hopper assembly 35 includes a collection hopper 351, and an asphalt pump 352 is connected to the bottom of the collection hopper 351. A flexible scraper 353 is obliquely arranged in the cavity on the top surface of the collection hopper 351. The upper end of the flexible scraper 353 flexibly abuts against the bottom surface of the conveyor belt 34. A discharge hose 354 and a discharge fixing pipe 355 are connected to the discharge end of the asphalt pump 352. The discharge fixing pipe 355 extends and is fixedly installed on the hopper box 21.

[0045] The lifting front wheel 5 is assembled from a lifting slide block 51, a second oil cylinder 52, a front wheel shock absorber 53 and a front wheel 54. The lifting slide block 51 is fitted inside the lifting slide rail 15.

[0046] Working principle:

[0047] During asphalt pavement construction, an external tractor is used to drive the equipment. Then, the pull-out valve 24 is opened to allow the asphalt material to flow out from the expansion nozzle 26 onto the roadbed. At this time, the asphalt material on the roadbed will be irregular and uneven, and needs to be leveled and paved by the paving mechanism 3.

[0048] It should be noted that when the hopper group 2 moves to the left to discharge material, after the draw plate valve 24 is opened, the asphalt raw material will flow down from the discharge square pipe 23, and the vibrator 25 will be activated to vibrate the hopper box 21 to assist in the discharge and prevent material jamming. In addition, the flow diffuser 26 is diverted by the flow divider plate 261 to expand the flow of material. The width of the asphalt raw material discharged through the flow diffuser 26 is the width of the asphalt pavement to be laid, but the longitudinal length of the flow diffuser 26 must be less than the length of the leveling guide plate 312.

[0049] Then, the paving mechanism 3 is lowered, and the height between the bottom surface of the paving mechanism 3 and the roadbed surface is adjusted to limit the thickness of the asphalt pavement. When the paving mechanism 3 paves the asphalt raw material from right to left, it is initially leveled by the leveling guide plate 312. However, at this time, due to the uneven distribution of the asphalt raw material, there will still be some unevenness caused by material shortage. Then, the compensation aggregate plate 313 is used to compensate for the unevenness caused by material shortage and fill it, and then the paving is leveled again. Then, the excess asphalt raw material is pushed to the right onto the conveyor belt 34 and transported to the guide hopper group 35 by the conveyor belt 34. Then, the guide hopper group 35 returns the excess asphalt raw material to the hopper box 21.

[0050] It should be noted that when the leveling guide plate 312 is initially pushed to the left to level and spread the material, the excess asphalt material first forms an accumulation state on the left front side of the leveling guide plate 312. After the accumulation height increases, it continues to be guided to the right through the feeding channel 3113 and the various staggered guide baffles 3122 to guide the asphalt material into the compensation aggregate chamber 3112, thereby realizing the staggered guidance of the excess asphalt material and automatically filling the uneven surface caused by material shortage.

[0051] The remaining material in the compensation collection chamber 3112 will continue to accumulate on the left front side of the compensation collection plate 313. After the accumulation height increases, it will be guided to the right through the collection channel 3114 and onto the conveyor belt 34. This can achieve automatic initial leveling and spreading, and then automatically fill the uneven surface by collecting excess raw materials, thus completing the automatic compensation and filling operation.

[0052] When the conveyor belt 34 guides material to the collection hopper 351, the flexible scraper 353 will scrape the bottom surface of the conveyor belt 34 to prevent the raw material from sticking to the conveyor belt 34. The cooperation of the asphalt pump 352, the discharge hose 354, and the discharge fixing pipe 355 to return the remaining material in the collection hopper 351 to the hopper box 21 for reuse is a conventional technology, which will not be elaborated on here.

[0053] Finally, when the compaction roller body 4 moves to the left, it will roll and compact the asphalt road surface that has been laid and leveled on the left. When the compaction roller body 4 rolls onto the asphalt road surface, the frame group 1 will tilt slightly to the left. It is necessary to adjust the frame group 1 to a horizontal state by raising the lifting front wheel 5 and sensing the horizontal sensor 6 before continuing to lay the asphalt road surface to the left.

[0054] Furthermore, the lifting of the front lifting wheel 5 and the sensing of the level sensor 6 work together to adjust the frame assembly 1 in a timely manner, which is a conventional technology and will not be elaborated on here.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
