Description

Technical Field

[0001] The present invention relates to the technical field of municipal road engineering equipment, and in particular provides a municipal road pavement construction equipment. Background Art

[0002] A paver is a heavy mechanical equipment specifically used for paving asphalt or concrete pavements. Its main function is to evenly lay asphalt or concrete on the roadbed to form a solid and flat road surface. It is an indispensable equipment in the construction of infrastructure such as new roads, expressways, and highways, which can improve the construction efficiency and pavement quality. However, some current pavers are relatively bulky due to their structural design, making it difficult to accurately adjust the paving position. Moreover, they lack effective shock absorption during paving, and thus are easily affected by uneven ground or uneven materials during the paving process, resulting in deformation during the paving process, which affects the flatness and thickness uniformity of the road surface, and is prone to vibration and loosening phenomena, affecting the stability and paving effect of subsequent equipment.

[0040] For example, in one embodiment: the height of the feed chute 616 on the re-paving assembly 50 is less than the height of the feed chute 616 on the primary paving assembly 40. The top of the filling pipe 11 is connected to an external mobile feeding device for asphalt or concrete. An elastic hanging strip is convexly provided at the bottom of the inner side of the material leveling groove 618. A plurality of height sensors are arranged at intervals along the length direction on the inner side of the regulating cavity 614 of the re-paving assembly 50. A sealing sheet is arranged in the preset rotating groove 681, and the rotating shaft 682 is turned to rotate and fit with the sealing sheet to prevent leakage of asphalt or concrete when it rotates.

[0041] For example, in one embodiment: when paving operations are being performed, two regulating cylinders 24 are activated to extend the output shafts of the regulating cylinders 24, causing the two regulating mounting strips 23 to rotate downward until the bottom surface of the leveling vertical arc plate 642 of the initial paving assembly 40 is set on the surface to be paved, and the leveling vertical arc plate 642 of the initial paving assembly 40 can sweep away movable stones and other protrusions that are higher than the surface to be paved. Subsequently, the lateral adjustment cylinder 36 on the adjacent initial paving assembly 40 is activated, thereby pulling the connecting adjustment block 610 to move along the lateral adjustment slot 34, so that the initial paving assembly 40 follows the movement until it moves to the lateral position to be paved, and then the lateral adjustment cylinder 36 on the adjacent re-paving assembly 50 is activated to pull the re-paving assembly 50 to move, until. The re-paving assembly 50 is arranged opposite to the initial paving assembly 40. Subsequently, the external mobile feeding equipment is started to feed the asphalt or concrete along the filling pipe 11 and the hose into the mixing and feeding chamber 612 of the initial paving assembly 40 and the re-paving assembly 50. Subsequently, the stirring motor 622 is started to drive the stirring shaft 621 to rotate to re-mix the asphalt or concrete to ensure the uniformity during the paving process and the subsequent feeding speed. Subsequently, the multiple upward opening cylinders 632 in the initial paving assembly 40 will be started synchronously, pulling the multiple closed rotating blocks 635 to rotate upward, so that the feeding chute 616 is opened. At the same time, the rotating upward closed rotating block 635 will push the linkage holding rod 686 to follow the movement, thereby causing the trigger shaft 685 to rotate, thereby causing the trigger lever 687 to The paving assembly 50 moves along with the movement, and then the triggering rotating plate 684 is toggled to rotate along with the rotation, so that the toggle rotating shaft 682 rotates, and the closing sealing plate 683 rotates along with the rotation, so that the asphalt or concrete will be inclined to flow out through the inclined discharge port 615 and multiple material discharge troughs 616 to between the leveling vertical arc plate 642 and the rolling rotating column 641, and with the movement of the paving operation, it is scraped and leveled by the elastic arc pressure piece 645 and the two elastic hanging strips to achieve preliminary leveling. Subsequently, the height sensor of the paving assembly 50 will scan the preliminary leveled ground to identify the leveling, and according to the result, the relatively set upward opening cylinder 632 will be relatively started for the concave or insufficiently leveled position, thereby pulling the corresponding closing rotating block 635 to move, so that the feeding channel 693 is connected with the material discharge trough 616, so that The asphalt or concrete falls to add to the concave or insufficiently leveled positions. At the same time, since the bottom surface of the closed rotating block 635 is concavely provided with a pressing arc surface 692, and the closed rotating block 635 of the flattened part is still at the bottom at this time, the pressing arc surface 692 on the closed rotating block 635 is used to press against the elastic arc pressure plate 645 to apply pressure to the rolling rotating column 641, thereby increasing the flatness of the paving and leveling. When the vibration is sent, the elastic arc pressure plate 645 buffers the vibration, and the remaining vibration force will be transmitted along the closed rotating block 635 of the re-paving assembly 50 to the elastic arc block 691 for re-shock absorption. In addition, the regulating shaft 633 connected to the closed rotating block 635 will also transmit the vibration to the return spring 644 for re-shock absorption to ensure stability during the paving process.

[0042] For example, in one embodiment: when the ground is uneven and there are protrusions, the protrusions will push the leveling vertical arc plate 642, and then cause the two mounting vertical sliding plates 646 to move upward along the linkage vertical sliding grooves 663, and then cause the rolling column 641 to move upward, so as to avoid excessive pressure during paving and leveling resulting in vibration. When the protrusion is too large, it will cause the mounting vertical sliding plate 646 to move upward significantly, and then cause the second conductive sheet on the electric control inclined surface 648 to contact the first conductive sheet, and send a signal to the multiple upward moving opening cylinders 632 of the re-paving assembly 50 and the downward pressing and closing cylinders 631 of the initial paving assembly 40. The downward pressing and closing cylinder 631 will drive the control connection rotating shaft 637 to move downward, and then cause the downward pressing and closing strip 634 to move downward, pushing the multiple closing rotating blocks 635 of the initial paving assembly 40 to rotate and move downward, reducing the opening degree of the multiple material discharging grooves 616 of the initial paving assembly 40, reducing the initial paving thickness, and slowing down the undulation. At the same time, the multiple upward moving opening cylinders 632 of the re-paving assembly 50 will synchronously pull the multiple closing rotating blocks 635 upward, so that the multiple inclined material discharging ports 615 and the multiple material discharging grooves 616 are communicated, so as to ensure that the subsequent paving thickness is supplemented and the subsequent paving flatness is ensured. When the ground is uneven and the undulation is large, the vibration situation is slowed down through secondary paving, the smoothness of the paving process is ensured, the vibration situation is reduced, and the paving flatness is ensured.

[0044] The present invention can achieve:

[0045] 1.
