Paver

Abstract

The invention discloses a paver. The paver comprises a vehicle body, wherein a vehicle frame is arranged on a rear portion of the vehicle body in the advancing direction of the vehicle body, and a reinforcing mesh laying mechanism and a concrete paving mechanism are sequentially arranged on the vehicle frame in a suspended mode, the reinforcing steel mesh laying mechanism is provided with a transverse reinforcing steel bar laying assembly, a longitudinal reinforcing steel bar guiding assembly is arranged in front of the transverse reinforcing steel bar laying assembly in the advancing direction of the vehicle body, the longitudinal reinforcing steel bar guide assembly guides a plurality of longitudinal reinforcing steel bars laid at equal intervals in the advancing direction and lifts up the longitudinal reinforcing steel bars in the vertical direction, the transverse reinforcing steel bar laying assembly rotates towards the advancing direction and lays the transverse reinforcing steelbars on the vertically-lifted longitudinal reinforcing steel bars at equal intervals in the advancing direction to form a criss-cross reinforcing steel bar net, and the concrete paving mechanism is provided with a vibrating paving main body and an expansion joint cutting mechanism. The paver integrates procedures of feeding, reinforcing mesh laying, guniting, concrete mixing, concrete flattening,expansion joint cutting and the like, and is compact in structure and suitable for concrete paving of various wide and narrow pavements.

Description

technical field [0001] The invention belongs to the field of special equipment for road construction, in particular to a paving machine. Background technique [0002] When building roads and laying concrete foundations, it is often necessary to evenly rake piles of concrete and spread them on the road surface. There are generally two methods in the paving process. One is manual raking construction operations, but this method requires a lot of Manpower, high labor intensity, poor paving uniformity, uneven pavement concrete density, slow construction progress, low efficiency and other shortcomings; another way is to use large cement paving machines, but the existing paving machines are expensive and require a large investment , high transportation costs, resulting in a significant increase in engineering costs. Moreover, the existing paving machines are mainly concentrated in the rear for secondary paving of the stacked materials, which are large in size and high in cost, and...

AI Technical Summary

Problems solved by technology

[0004] Continuously reinforced concrete pavement has a sufficient number of steel bars arranged horizontally and vertically to form a steel mesh. At present, the construction method of laying steel mesh is still manual laying and manual node fixing. Not only the labor cost is high, but also because different workers have different technical levels. , the node fixing strength and laying quality cannot be guaranteed
