Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, in particular to a concrete pavement paving device for engineering construction. Background Art

[0002] When constructing a concrete road, it is necessary to lay the roadbed first. After the roadbed has passed the leveling pressure test and has passed the acceptance, the concrete can be laid. Before pouring concrete on the road surface, a template needs to be laid on the roadbed surface. The template can not only limit the thickness of the concrete, but also avoid concrete turbulence and make the roadside neat. During construction, the concrete truck is dumped on the construction road surface and the concrete is piled on the road surface. Before leveling the road surface, the concrete roadbed needs to be spread out from the piled state to make it a relatively flat whole, which is convenient for the subsequent construction process. The spreading measures when laying concrete are generally manual leveling. Manual spreading and leveling generally means that workers simply use tools such as shovels to spread the concrete piled on the road surface on the road surface, and then pull the flat plate to directly level the concrete. After leveling, use vibration equipment to vibrate to expel the bubbles inside the concrete.

[0003] At present, manual paving of concrete pavement easily leads to uneven concrete aggregate, and it is also necessary to lay formwork to limit the thickness of the concrete and the neatness of the edges. The construction speed is slow, and the curb needs to be constructed separately after the concrete hardens. Summary of the invention

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a concrete pavement paving device for engineering construction, which has the following beneficial effects:

[0024] 1. When the present invention is in use, the fourth hydraulic motor is first started to drive the half shaft to rotate the driving gear, and the rotation of the driving gear drives the inner gear ring to rotate the inner ring of the support bearing, and the rotation of the inner ring of the support bearing drives the mounting plate to rotate the telescopic arm, the paving mechanism and the shaping mechanism, and then the electric push rod is started to push the positioning pin to be clamped in the positioning groove for positioning, and then the fourth hydraulic cylinder is started to push the telescopic arm, the paving mechanism and the shaping mechanism to swing around the first small pin and the second pin. At this time, the concrete material can be put into the material box and the shaping mechanism can continuously lay out a strip-shaped curb structure on the road surface, and the travel speed can be controlled by the crawler machine. After the curb structure is laid, the device is reset, and then the concrete can be put into the material box for paving, and the paving mechanism can evenly spread the concrete on the roadbed surface, and can achieve vibration smoothing after paving. By starting the third hydraulic cylinder, the back plate can be driven to move the paving mechanism in the first shell and the second shell to control the thickness of the concrete. In this way, the concrete of the curb and the road surface can be laid on the road surface, and the laying thickness can be controlled, and there is no need to lay a template on the roadbed surface, thereby improving the construction speed.

[0025] 2. The paving mechanism provided in the present invention, when in use, first starts the first hydraulic cylinder to retract and pull the guide frame to make the second shell body away from the first shell body, so that a discharge channel is formed at the lower ends of the first shell body and the second shell body, and the concrete in the material box passes through the discharge port and enters between the first shell body and the second shell body from the feed port. At this time, the first hydraulic motor is started to drive the feeding auger to rotate. When the feeding auger rotates, it uses two spiral blades with opposite rotation directions to transport between the first shell body and the second shell body. At this time, concrete flows out from the gap at the lower ends of the first shell body and the second shell body to the ground, and is scraped flat by the scraper. In addition, a vibration motor can be used for vibration during scraping, so that the paved concrete can be vibrated and scraped flat, and then the paved concrete can be manually refined, so that the construction speed of the concrete pavement can be improved, and the inclination angle of the paving mechanism is adjusted by the fourth hydraulic cylinder on the telescopic arm, so that the concrete pavement is an inclined plane, which is beneficial to the later drainage of the pavement.

[0026] 3. The shaping mechanism provided in the present invention, when in use, first starts the first hydraulic cylinder to work and push the first shell, and pulls the second shell in the opposite direction through the guide frame to reset. At this time, the first shell and the second shell form a closed cylindrical structure, and the concrete cannot flow out at this time. Then the material box is pushed to one end of the first shell and the second shell, so that the concrete discharged from the lower end is unidirectionally conveyed by one section of the spiral blade on the feeding screw, and the concrete passes through the circular opening on the rectangular plate and enters the end cover. Then the third hydraulic motor is started to drive the transmission shaft to make the spiral plate push the rod concrete to be discharged from the discharge port into the shaping shell, and the concrete in the shaping shell is squeezed into strips and pressed into blocks. When the eccentric wheel rotates, the driving shaft drives the eccentric wheel to rotate. When the eccentric wheel rotates, the driving plate moves back and forth through the rectangular hole. At this time, the pressing block can be used to beat the concrete squeezed into strips, so that the concrete is further compacted. At the same time, when the driving shaft rotates, it drives the first bevel gear to rotate the second bevel gear. The rotation of the second bevel gear drives the supporting shaft to rotate the sprocket. When the sprocket rotates, the main shaft rotates through the chain and another sprocket. When the main shaft rotates, it drives the shaping roller to rotate. When the shaping roller rotates, it can rub the upper end of the concrete strip. At this time, the upper end of the curb can be shaped to make it smooth and without indentations, thereby improving the construction of concrete pavement curbs. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The shaping mechanism provided in the present invention, when in use, first starts the first hydraulic cylinder 17 to work and push the first shell 6, and pulls the second shell 7 in the opposite direction through the guide frame 18 to reset. At this time, the first shell 6 and the second shell 7 form a closed cylindrical structure, and the concrete cannot flow out at this time. Then the material box 10 is pushed to one end of the first shell 6 and the second shell 7, so that the concrete discharged from the lower end is unidirectionally conveyed by one section of the spiral blade on the feeding screw, and the concrete passes through the circular opening on the rectangular plate 30 and enters the end cover 24. Then the third hydraulic motor 25 is started to drive the transmission shaft so that the spiral plate 32 pushes the rod concrete to be discharged from the discharge port 46 into the shaping shell 22, and the concrete in the shaping shell 22 is squeezed into strips and pressed into the block 45. When the transmission shaft rotates, it drives the eccentric wheel 40 to rotate. When the eccentric wheel 40 rotates, the transmission plate 41 reciprocates through the rectangular hole. At this time, the pressing block 45 can be used to beat the concrete extruded into strips, so that the concrete is further compacted. At the same time, when the transmission shaft rotates, it drives the first bevel gear 35 to rotate the second bevel gear 36. The rotation of the second bevel gear 36 drives the support shaft to rotate the sprocket 39. When the sprocket 39 rotates, the main shaft rotates through the chain 37 and another sprocket 39. When the main shaft rotates, it drives the shaping roller 38 to rotate. When the shaping roller 38 rotates, it can rub the upper end of the concrete strip. At this time, the upper end of the curb can be shaped to make it smooth and without indentations, thereby improving the construction of the curb of the concrete pavement.
