Embodiment 1

[0028] Embodiment 1, the metal mesh roll automatic flattener that is used for pavement pouring type asphalt pavement, the metal mesh roll is a copper wire mesh roll, and this road surface includes bridge deck, see figure 1 , figure 2 and Figure 7 , comprising an unwinding mechanism 1 for placing copper wire mesh rolls arranged on the vehicle frame 4, a flattening mechanism 2 for flattening copper wire mesh rolls, and a paving mechanism 3 for laying copper wire mesh, and the paving mechanism 3 includes pressing down Device 31, the pressing device 31 includes a pressing roller 311, and the pressing roller 311 is arranged above the place where the copper wire mesh is placed.

Embodiment 2

[0029] Embodiment 2, what adopted in the present embodiment is steel wire mesh coil, on the basis of embodiment 1, pavement mechanism 3 in the present embodiment also comprises road surface heating device 32, and road surface heating device 32 heats the asphalt of road surface, Increase the viscosity of the asphalt, combined with the lower pressure roller 311 to apply a vertical force, so that the steel wire mesh can be embedded in the road asphalt.

[0030] see Figure 7 , the road surface heating device 32 can also be connected with the lower pressure roller 311 through the tie rod 312, so that the lower pressure roller 311 has the function of heating the road surface asphalt and exerting a vertical downward force on the steel wire mesh at the same time, which can ensure that the lower pressure roller 311 is pressed The automatic healing of the asphalt pavement after passing can eliminate the adhesion of asphalt on the lower pressure roller 311, thereby ensuring the flatness...

Abstract

An automatic metal net roll flattening machine for cast asphalt pavement of a road surface comprises an unwinding mechanism, a flattening mechanism and a laying mechanism, which are arranged on a frame, wherein the laying mechanism comprises a pressing-down device; the pressing-down device comprises a pressing-down roller; and the pressing-down roller is arranged above a metal net touchdown position. The automatic metal net roll flattening machine for the cast asphalt pavement of the road surface, provided by the invention, is advantaged in that unwinding, flattening and laying are integrated; as a metal net can sink into asphalt of the road through the adoption of the pressing-down mechanism, problems in the prior art that transverse cracks are prone to form at connections of the metal net and the metal nets are prone to lose balance when secondary road laying equipment moves on the metal nets are solved; and as the density of a hot-mix asphalt mixture in the upper layer is high, rusting, necking and fracture phenomena of the metal nets caused by the invasion of water are avoided; the construction quality is effectively improved; and the working efficiency is effectively increased.

Description

technical field [0001] The invention relates to an automatic flattening machine for metal mesh rolls, in particular to an automatic flattening machine for metal mesh rolls used for pouring asphalt pavement on road surfaces. Background technique [0002] With the in-depth research on the characteristics of asphalt mixture, anti-reflection cracks, differential settlement and other technologies, the technology of double-layer paving of cast asphalt mixture and metal mesh reinforcement has become a hot spot technology for asphalt mixture paving of road and bridge decks. Laying metal mesh reinforcement between the base course and the surface course can provide sufficient tensile capacity to prevent reflection cracks, pavement delamination and differential settlement. At present, in the construction process of pouring asphalt pavement, metal mesh rolls are usually flattened in different places and paved manually. This method of flattening in different places and manual paving c...
