Punching device used for building and working method thereof

Abstract

The invention relates to the technical field of construction equipment, in particular to a punching device used for building and a working method thereof. The punching device comprises blades, an alloy cutting head and a drill bit. The punching device is characterized in that the blades are arranged on the periphery of a rod body and are connected with the rod body in a welded mode; the alloy cutting head is arranged in the drill bit and is connected with the drill bit in the welded mode; the drill bit is arranged at one end of the rod body, and the drill bit and the rod body are each of an integrated structure; blade cutting heads are arranged at one ends of the blades and are connected with the blades in the welded mode; and a sleeve and a connector are each of an integrated structure, and the sleeve and the rod body are connected in the welded mode. Through improvement of the structure, the punching device used for building has the advantages that connecting is firm, punching residues are easy to discharge, the operating load is reduced, the punching condition is not limited, positioning during punching is accurate, perpendicularity of punching cavities is the same, and the punching performance is high, and the problems existing in an existing device are effectively solved.

Description

Technical field [0001] The present invention relates to the technical field of construction equipment, in particular to a punching device for construction and a working method thereof. Background technique [0002] With the rapid development of modernization, the construction industry has become the leader in many industries, and the construction projects are diverse and diversified. Especially the requirements for punching during construction are extremely demanding, and building punching devices have emerged. [0003] However, the currently used punching device has a weak fixed connection, which causes the device to fall off and damage the device during the punching process. The punching residue is not easy to discharge, which causes the device to overload during the punching process. The unreasonable structure design causes the sand and gravel conditions to suffer when punching. Limited by the hardness conditions, the concentric rotation of the running part leads to problems and...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a drilling device for construction and its working method, to solve the problems in the above background technology that the fixed connection is not firm enough to cause the device to fall off and damage the device during the drilling process, and the drilling residue is not easy to discharge, which leads to the occurrence of a hole in the drilling process. The device is overloaded, and the structural design is unreasonable, which leads to the limitation of hardness conditions when drilling holes in sand and gravel. The concentricity of the rotating running part leads to non-vertical drilling, and troublesome problems and deficiencies in replacement.
