Pavement leveling and paving equipment based on non-independent suspension

Abstract

The invention relates to the technical field of asphalt pavement leveling and discloses pavement leveling and paving equipment based on the non-independent suspension. The equipment comprises a vehicle body, tyres are movably connected to the two sides of the vehicle body. Spring rods are movably connected into the tires, damping plates are fixedly connected to the surfaces of the tires, storage boxes are movably connected to the ends, away from the tires, of the damping plates, friction wheels are movably connected into the storage boxes, driving rods are movably connected to the surfaces ofthe friction wheels, and compression springs are movably connected to the bottoms of the driving rods. The tire firstly contacts with the road surface; when the tire runs to the position above the convex road surface; due to the fact that the vehicle body is of a non-independent suspension design, the tires can jack up the vehicle body upwards, when the vehicle body inclines by a positive angle, the driving rod can be pulled to move upwards and stretch the compression spring, the friction wheel rotates to drive the leveling plate to deflect upwards as shown in Figure 6, the scraper makes contact with the protruding road surface, and the effect of scraping the protruding road surface is achieved.

Description

Technical field [0001] The invention relates to the technical field of asphalt pavement leveling, in particular to a pavement leveling and paving equipment based on a non-independent suspension. Background technique [0002] With the rapid development of my country's economy, cities occupy more and more ground, and the reciprocating highways between cities are developing rapidly, and people's requirements for driving comfort are getting higher and higher. [0003] Most expressways in our country are cement pavement and asphalt pavement. Among them, asphalt pavement has the characteristics of convenient repair and low cost, and it occupies the main paving position. The paving of asphalt pavement adopts pavement paving machine to heat the asphalt and then pour it on the relatively flat ground. , And then flatten it with a roller. [0004] Traditional road-leveling equipment, mostly heavy-duty vehicles with large wheels, reciprocate and level the road surface many times. Although this ...

Problems solved by technology

[0004] Traditional road surface leveling equipment is mostly heavy-duty motor vehicles with large rims, which reciprocate and level the road surface many times. Although this equipment can roughly level the road surface, it is difficult to It is not easy to be contacted by the wheel hub with a large diameter, so it cannot be leveled accurately; in addition, the existing road leveling equipment can only be repaired in large areas, and small potholes and protrusions need to be repaired manually. There are certain errors in manual repair, and the repaired road surface is not smooth, so a road leveling and paving equipment based on non-independent suspension came into being
