Dustproof type concrete prefabricated block drilling device for building construction

Abstract

A dustproof type concrete prefabricated block drilling device for building construction comprises a supporting frame, a driven shaft is arranged on the supporting frame in a vertical sliding manner, a cam is fixedly mounted on the driven shaft, a drill bit is vertically arranged at the bottom end of the driven shaft, a wedge block is fixed to the right end of a first sliding rod, the left end of a first limiting spring is fixed to a sleeve on the right side of the driven shaft, and a roller is in abut joint with the wedge face of the wedge block; a right cover plate is hinged to a dust suction pipe, and is located in a dust suction box, a left cover plate is hinged to a dust exhaust pipe, and is located outside the dust suction box, an air suction sleeve is arranged on the dust suction box and communicates with the dust suction box, dust generated during drilling of the dust suction pipe is conveyed to the dust suction box, a piston rod drives a water drawing piston head to vertically move in a reciprocated manner, tap water is sprayed to the drill bit and a concrete prefabricated block through a spraying head, the dust falling and removing effect is further achieved, and the drill bit is subject to water cooling; the temperature of the drill bit is effectively reduced, and the drilling quality is improved.

Description

technical field [0001] The invention relates to the technical field of building material cutting equipment, in particular to a dust-proof concrete prefabricated block drilling device for building construction. Background technique [0002] Concrete refers to a mixture made of cementitious materials, granular aggregates, water, chemical admixtures and mineral admixtures that need to be added in an appropriate proportion, or a composite material with a stacked structure after hardening. Concrete It is one of the most important contemporary civil engineering materials; concrete has the characteristics of abundant raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used. It is not only used in various civil engineering, but also in shipbuilding, machinery industry, ma...

Problems solved by technology

[0003] After the concrete prefabricated block is finished, according to the actual customization requirements, the concrete prefabricated block needs to be further processed, including cutting, drilling and other processing methods. When drilling, the existing concrete prefabricated block drilling device lacks effective Dust removal and dust reduction measures generate a large amount of inhalable dust in the operating area during drilling, which seriously affects the health of operators. At the same time, the drill bits used for drilling cannot be cooled, and the drilling quality is difficult to guarantee.
