Vertical height-adjustable drilling equipment

Abstract

Vertical height-adjustable drilling equipment comprises a base plate, a transverse plate, a motor device, air cylinder devices, a supporting device and a drilling structure; first supporting blocks, first idler wheels, a first supporting rod, a first supporting frame and a second supporting rod are disposed on the base plate; second supporting frames, a first transverse rod, first springs, a supporting block, second springs and fixing rings are disposed on the transverse plate; the motor device comprises a motor, a third supporting rod, a third supporting frame, a second transverse rod, a first spindle and a gear; each air cylinder device comprises an air cylinder, a fourth supporting frame, a pushing rod, a second idler wheel and a fifth supporting frame; the drilling structure comprises a drilling rod, a drilling head, a ring gear, a first vertical rod, a bulb and a fixing ring; the supporting device comprises a fixed block, third springs positioned upon the fixed block, supporting rings positioned on both sides of the fixed block, bracing wires and fourth springs positioned under the fixed block. The drilling equipment disclosed by the invention can drill bores on demanded positions automatically, and reduces the labor intensity of manual work greatly.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a drilling device with adjustable vertical height. Background technique [0002] In construction engineering, it is necessary to mechanically drill holes under floor slabs and beams in many occasions, such as the pattern needs to be implanted with ribs, hanger rods, etc., but the existing measures are to manually stand on the double-sided ladder and hold the impact drill. In this way, when a person operates on the ladder, one or two people below must support the ladder, otherwise there will be a safety hazard of toppling over. Since the person is close to the operation surface, the drilled powder particles are easily inhaled into the respiratory tract of the worker, seriously affecting Workers' health. [0003] Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Contents of the invention [0004] The object of t...
