Description

Concrete paving distributor and paver

Technical Field

The invention relates to the technical field of engineering machinery, in particular to a concrete paving distributor and a paver.

Background

Understanding that: the concrete paver is a construction equipment mainly used for paving the concrete on the base course and the surface course. When cement is filled and paved on a road, the filled and paved cement is often required to be flattened in order to ensure the flatness of the cement filled and paved road, and at the moment, the manual paving method is labor-intensive and inconvenient, so that the cement needs to be paved by a machine. At present, when a concrete foundation is paved on a large road, a large cement concrete paver is usually adopted for operation, but the existing large paver is high in price, large in investment, high in transportation cost and difficult to maintain, so that the engineering cost is greatly increased, and a professional large paver technical operator is required to operate, so that the special property is strong, and most of pavements are still paved by adopting a rail mode paver when the road with the specification requirement not being very high is paved.

The track-mode concrete paver is generally composed of a distributor, a vibrator, a traveling leveling mechanism, a troweling device and other devices, and during construction, the paver runs on a fixed track mold to pave into a running belt, wherein the track mold is a running track of the paver and a side mold for paving a road surface.

And (3) retrieval: among the prior art, rail mounted concrete spreader when the operation that paves, at first will pour the concrete that stirs between two tracks, then draw the harrow by constructor with piling concrete and pave to the road surface, start the paver and advance along the track after that, pave the operation, adopt the artifical mode that draws the harrow and pave the concrete, need a large amount of manpowers, intensity of labour is big, and the construction progress is slow, and is inefficient.

Through patent library search, the following two documents are similar to the technical problems to be solved by the present application:

citation and summary: in the invention patent of the chinese patent No. 201910116232, the concrete in the hopper is conveyed to the spiral distributor by the conveyor belt, and the spiral distributor further conveys and lays the concrete, the efficiency of conveying the concrete by the spiral distributor is low, and the invention is only suitable for uniform paving of a small amount of concrete, so the concrete needs to be firstly pre-leveled and then secondarily paved by the spiral distributor, the concrete in the hopper is conveyed to the spiral distributor by the conveyor belt, and the conveying and laying of the concrete is realized by the spiral distributor, the conveying efficiency is slow, and the invention is not different from the method of directly conveying and laying by the spiral distributor.

In the invention patent of the chinese patent No. 202011566543, although the patent can also quickly spread the accumulated concrete, a gap exists between the two paving assemblies, so that a concrete ridge which is not completely spread is left on the rear side when paving is performed, and a spiral distributor is required to spread for the second time, thereby affecting the working efficiency, and the two paving assemblies are separately controlled by two motors, which may cause different rotation speeds, thereby causing uneven concrete spread on both sides.

Sometimes the upper end of rail mould can splash partial concrete or rubble, not clear up in time, and the concrete or rubble after the solidification can influence the effect of paving greatly on the rail mould to can lead to the fact wearing and tearing to the roller of marcing.

Therefore, the concrete paving distributor and the paving machine are provided to solve the problems.
