Hand-held drilling machine for road construction

Abstract

The invention provides a hand-held drilling machine for road construction, and relates to the field of road construction equipment. The hand-held drilling machine for road construction comprises a base plate, a fixing rod is fixedly arranged at the top of the base plate, a top plate is fixedly arranged at the top of the fixing rod, a box body is arranged in the fixing rod, a drilling device is fixedly arranged at the bottom of the inner wall of the box body, a baffle is fixedly arranged at the top of the inner wall of the box body, two limiting columns are fixedly arranged at the two ends of the bottom of the baffle and are fixedly connected through a transverse rod, a spring movably sleeves the outer surface of the transverse rod, and movable sliding sleeves are fixedly arranged at the two ends of the spring. The hand-held drilling machine for road construction has the advantages that a drilling machine body is enabled to be perpendicular to the ground through hydraulic push rods, sothat time is saved, operation is convenient, the movable sliding sleeves and connecting rods are coordinated for use, so that the spring plays a role in buffering the drilling device, and therefore the phenomenon that the work of the drilling machine is affected by vibration generated in the drilling process can be avoided, physical power can be saved, and convenience can be brought to people.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular to a hand-held drilling machine for road construction. Background technique [0002] During road construction, a hand-held drilling machine is needed to drill holes on the ground. The drilling machine refers to using a tool that is harder and sharper than the target object to leave a hole on the target object by means of rotary cutting or rotary extrusion. A general term for machines and devices with cylindrical holes or holes. [0003] At present, the hand-held drilling machines generally used for road construction on the market are inconvenient to drill vertically and cannot be truly perpendicular to the ground. Vibration will be generated when drilling, which will affect the operation of workers and affect the work efficiency of workers. At the same time, when drilling holes on the ground, dust and debris will be generated, which will pollute the environment ...
