Drilling device used for road engineering

Abstract

The invention discloses a drilling device used for road engineering. The drilling device comprises a rack, wherein push rods are arranged at two ends of the top of the rack respectively; a second supporting plate is arranged at the bottom of the rack; a telescopic rod is arranged between the rack and the second supporting plate; pulley columns are arranged at two ends of the bottom of the second supporting plate respectively; a pulley is arranged at the bottom of each pulley column; a first supporting plate is arranged at the bottom of the rack; two ends of the first supporting plate are fixedly connected with the telescopic rod; a motor is arranged at the top of the rack; the output shaft end of the motor is connected with a drill sleeve; a damping spring is arranged outside the drill sleeve in a sleeving mode; and the top of the damping spring is connected with the bottom of the rack. The drilling device is provided with the damping spring made of a silicomanganese spring steel material, the vibratory sensation of a drilling machine can be alleviated effectively, moreover, a spongy layer is arranged outside each push rod in the sleeving mode, influences of the equipment on constructors can be further reduced, and the operation of the constructors is facilitated preferably.

Description

technical field [0001] The invention relates to the field of road engineering construction, in particular to a drilling device for road engineering. Background technique [0002] Highway drilling machine is widely used in cement pavement drilling of roads and highways, drilling of limestone layers, and can also be used in drilling operations before installation of guardrail columns in highways, highways, and traffic safety projects; at present, with road With the continuous improvement of construction, the road drilling machine has also been relatively improved, but the road drilling machine is relatively large in size. When using small road sections for construction, this type of large drilling machine is relatively cumbersome, and the consumption during construction It is also relatively huge, and although the small drilling machine can meet the construction of small road sections, it will generate huge vibrations when drilling, which will easily cause numbness in the work...

[0002] Highway drilling machine is widely used in cement pavement drilling of roads and highways, drilling of limestone layers, and can also be used in drilling operations before the installation of guardrail columns in highways, highways, and traffic safety projects; at present, with road With the continuous improvement of construction, the road drilling machine has also been relatively improved. However, the road drilling machine has a relatively large volume. It is also relatively huge, and although the small drilling machine can meet the construction of small road sections, it will generate huge vibrations when drilling, which will easily cause numbness in the workers' arms, which is not conducive to construction.
