Description

Rotary simple chiseling device

Technical Field

The utility model belongs to the technical field of engineering machine tool device technique and specifically relates to indicate a simple and easy chisel hair device of rotation type.

Background

The chiseling process is one of the main processes for rough treatment of the interfaces of the new and old concrete, and the quality of the chiseling effect directly influences the combination quality of the new and old concrete, thereby influencing the service life of the structure. The traditional manual roughening, brushing and mechanical grooving have low process efficiency and can not thoroughly remove floating slurry; although the milling process can solve the problem of laitance, the concrete surface is easy to loosen and damage, and grooves with different depths are formed to be not beneficial to surface cleaning; in the shot blasting machine process, the impact force is not too large when steel shots are roughened, the flatness of a working surface is better after construction, but the roughening depth is shallow, the concave-convex pitted surface is not obvious, the bonding between new and old concrete is not good, in addition, the steel shots for roughening are difficult to recover, and the price of a road surface shot blasting machine is not very high; and although the construction galling efficiency is high, a weak layer is formed on the surface of the concrete.

The existing chiseling method generally has two types, namely manual type (using a stabber) and mechanical type (using a chiseling machine). The method has the disadvantages that the steel chisel and the hammer are required to be used for complete manual operation, the technical level of workers is uneven, the chiseling effect is not ideal, the working efficiency is low, especially, dust generated during chiseling has large harm to the workers, the workers are easy to fatigue, the personnel investment is large, the impact on a bridge floor is large, the construction cannot be carried out when the strength of the concrete is low, and the chiseling construction in the mode can be carried out after paving is finished for 10 days generally; the mechanical chiseling is mainly characterized in that a small air compressor is connected with an air pick through an air pipe, high-pressure air generated by the air compressor drives the air pick to chisel the concrete to expose a fresh concrete surface, loose concrete stones, scraps and the like are manually removed, and the mechanical chiseling is high in chiseling speed and good in chiseling effect and has the defects of high noise generated during construction, and limitation caused by the reasons that the air compressor is heavy, the air pipe is not long enough, the conditions of a construction site (particularly, the conditions are not suitable for narrow, narrow and steep interfaces) and the like. In addition, when the existing chiseling machine chisels, the chiseled grooves are uneven in width and width, even the grooves are bent, so that the gap and distance between the grooves on the whole rough surface are seriously uneven, the binding force is uneven when new and old concrete is combined, and the local serious quality problem is easy to occur.
