Description

Intelligent multi-purpose anti-segregation paver with large width and thickness Technical field

The invention belongs to the technical field of paver, and particularly relates to an intelligent multi-purpose large-width and thick-thickness anti-segregation paver.

Background technique

When pavers are laying highways, they often enter and exit tunnels and bridges and culverts. The width of the pavement inside and outside the tunnels and bridges and culverts is different. The pavement entering the tunnels and bridges and culverts becomes narrower. It is different between different highways. In recent years, the width of tunnels, bridges and culverts of paved highways has become more and more wide-ranging. Construction on such road sections is traditionally mechanically connected and widened. When entering tunnels, bridges and culverts, the machine must be disassembled and narrowed. After exiting the tunnel, the connection is widened to adapt to road changes. However, with the continuous development of road construction and the construction of highways in mountain areas, the traditional flat-loaded screw conveying mechanism has been unable to meet the large-scale changes between tunnels, bridges and culverts and normal roads, and this contradiction is increasingly prominent. .

In recent years, the paver of the mixed material gradually develops in the direction of large width, large thickness, high productivity, high operation quality and multi-function. One of the key technologies to ensure high operation quality under large width and high productivity is the spiral distributor. The main part of the pavement machine to produce isolated defects is in the spiral material distribution process, and the link with the largest power consumption during the operation is also in the spiral material distribution process, which is about 50% to 60% of the power of the whole machine. At present, due to the consideration of power factors, various domestic paveres make the surface of the material in the spiral distributor located at 1 / 2-2 / 3 of the diameter of the spiral. In this way, when paving on a large-width, large-thick stable soil, in order to meet the requirements of the amount of material conveyed, the working speed of the spiral distributor must be increased. The high-speed rotating spiral lifts the material of the semi-buried spiral upward, which is the main reason for the mechanical segregation. The material full buried spiral enables the entire paving layer to be operated under spiral stirring and extrusion, which can effectively solve the segregation of paving materials, reduce the difference in compactness of the paving layer, and improve the smoothness of the road surface after rolling. However, the material full-buried spiral must have a reliable spiral drive system to improve work reliability. At present, the driving methods of various spiral spreaders of domestic and foreign pavers are chain driven, such as: ABG525, VÖGELE Super 2500 type paver. Such a drive system is overwhelmed by large-width and high-productivity operations. Frequent chain breaks bring great distress to the construction, and segregation occurs frequently, the service life of the highway is short, and the problem is prominent.

Summary of the Invention

The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an intelligent and versatile anti-segregation paver with large width and thickness. The paver can adapt to paving pavements with multiple changes in width and effectively improve the paving efficiency of the pavement. At the same time, it can ensure that the paving material is sufficient, thereby ensuring the smoothness and compactness of the pavement, effectively solving the problem of segregation of the mixed material, improving the quality of pavement paving, high construction efficiency, and prolonging the life of the pavement.

The other end of the telescopic oil cylinder 67 is hinged to the push roller assembly 65. The telescopic oil cylinder 67 is fixed in the guide chute 64 or fixed outside the guide chute 64. The hopper 6 includes a movable hopper and a main hopper 61. The movable hopper is composed of a fixed hopper 62 and a tipping hopper 63. The main hopper 61 is fixed to the paver. On the frame 1, the fixed bucket 62 and the dump bucket 63 are hinged on the rolling assembly 65.

As shown in Figures 9 and 10, the movable hopper can be retracted and retracted in the main hopper 61 under the action of the telescopic oil cylinder 67 and the roll assembly. The length of the main hopper 61 and the front and rear discharge of the hopper in the main hopper 61 can be adjusted. The position allows the material in the material cart to be quickly discharged into the paver hopper, reduces the contact time between the material cart and the paver, and realizes the uninterrupted continuous paving operation of the paver. The tipping hopper 63 in the movable hopper tilts backward as the movable hopper retracts, so that the material falls backward into the main hopper 61 and is then transported to the hopper behind the paver.

When the unloading starts, the movable hopper retracts and overlaps with the main hopper 61, and the material cart unloads to the rear of the main hopper 61. When the material accumulated in the main hopper 61 supports the car and cannot continue to discharge, the movable hopper is extended forward, and the total volume is pushed by the pusher. Cheng pushes the hopper forward in the main hopper 61, so that the materials in the hopper are dumped smoothly from back to front in the main hopper 61 until the main hopper 61 is full, and the last remaining material in the hopper is unloaded and fully extended. In the movable hopper, the movable hopper retracts when the car leaves, and at the same time, the dumper 63 in the movable hopper is tilted backward, so that the material accumulated in the dumper 63 completely falls into the main hopper 61, and then the dumper 63 is leveled and moved. After the hopper is fully extended forward again, the main hopper 61 is closed, the main hopper 61 is flattened again, and the movable hopper is retracted. The paver hopper completes a cycle of receiving materials in accordance with the above process.

The connection of the super-large-capacity main hopper 61 and the movable hopper forms a one-time lift of the material cart and a variable volume of unloading space (length and height) to ensure that the material in the material cart slides down and avoids multiple lifting of large material rolls. Falling, lifting, unscheduled insufficiency of material supply, etc., such as roll-off segregation, paving dense uniformity segregation, and uneven feeding.

The main hopper 61 has a volume of 10m ³ and the movable hopper has a volume of 2m ^{3. The} variable-volume dual hopper device enables sufficient storage of hopper 6 and realizes part of the functions of the material transfer truck. 2. Smooth unloading problems, improving paving compactness, evenness, and efficiency. The large-capacity hopper 6 has a large heat capacity and eases the degree of temperature segregation.

The forward movement of the movable hopper changes the unloading position, solves the problem of poor unloading of the tailings of the trolley, shortens the unloading time of the trolley, and ensures continuous operation of the construction. The tailings of the truck are discharged quickly and cleanly, avoiding the tailings falling on the pavement to be paved, and causing the hidden danger of quality of "nodules". It prevents the tailings from falling on the road surface to be paved, resulting in the deviation of the paving resistance and causing deviation in the direction of travel (paving swing). The unevenness of the pre-compaction on both sides of the screed 51 affects the flatness after compaction. The tilting and retracting function of the movable hopper prevents the scraper from being empty when the car is alternately intermittent, ensuring continuous paving. At the same time, the material at the front of hopper 6 is emptied by contraction and overturning to ensure that the lower part of the hopper 6 is not bedding. When the hopper is pushed forward, the material receiving space is increased to prevent the material from scattering from the front of hopper 6, which reduces auxiliary operations and reduces Labor intensity.

The hydraulic door hook device provided in the main hopper 61 prevents the back door of the feed truck from being stuck, and ensures that the rear door of the feed truck is fully opened, so that the feed truck is lifted into place and discharged quickly. The hydraulic telescopic rolling assembly 65 reduces the impact of the material truck and improves the flatness.
