An auxiliary device for laser cutting of concrete pavement

Abstract

The invention belongs to the field of road construction, and discloses an auxiliary device for laser cutting a concrete pavement. The device comprises a main body, a laser, a cutting mechanism, a lifting mechanism and an angle adjusting mechanism, The main body moves so as to change the cutting position; the cutting mechanism comprises multiple cutting heads arranged in parallel; each cutting headis used for emitting a laser light for cutting the concrete pavement; two groups of cutting heads are arranged; the cutting directions of the cutting heads in each group have the same direction; whenthe laser lights emitted by the two groups of cutting heads are intersected, a part to be cut is separated from an original concrete pavement, so that the concrete pavement is cut and crushed; the angle adjusting mechanism is used for adjusting the angle of each cutting head; and the lifting mechanism is used for adjusting the distance between the cutting mechanism and the ground. Through the auxiliary device for laser cutting the concrete pavement provided by the invention, the laser lights are adopted to cut and crush concrete in a non-contact way, so that the reinforced concrete pavement containing a reinforcing mesh is effectively cut, the cutting and crushing efficiency is high, and the impact vibration and the noise and dust pollution produced during the concrete pavement crushing process are effectively avoided.

Description

Technical field [0001] The invention belongs to the field of road construction, and more specifically, relates to a concrete pavement laser cutting auxiliary device. Background technique [0002] Concrete is widely used in the construction of houses, bridges, tunnels and roads because of its easy construction, high strength, long service life, and strong ability to withstand external forces. As a common type of road structure, cement concrete pavement has the advantages of high rigidity, strong bearing capacity, good durability, high temperature resistance, high bending and tensile strength, and long fatigue life. It is widely used in national highways, provincial highways, Airports, factory and mine roads, etc. However, the construction process of the concrete pavement is very cumbersome, and the pavement needs to be crushed and then tiled. [0003] At present, the commonly used tools for breaking concrete roads are pneumatic picks, hydraulic breakers, and cement road breakers. ...

Problems solved by technology

However, the reconstruction process of concrete pavement is very cumbersome, and the pavement needs to be crushed and then paved

[0003] At present, the commonly used tools for breaking concrete pavement include jackhammers, hydraulic breakers, and cement pavement crushers. Noise, and even accidents caused by splashing gravel, so it is not suitable for road construction in densely populated cities, especially near hospitals, schools and residential buildings. The noise generated by wind pick construction will greatly affect people's lives

And now, in order to improve the mechanical properties of concrete roads, steel mesh is often laid in cement concrete. Commonly used concrete breaking tools can only break concrete stones, and it is difficult to cut steel bars, so the construction efficiency is low.
