Abstract

The invention discloses a hydraulic engineering driller which adopts a drilling hydraulic cylinder and a hydraulic motor driven drilling bit component for drilling; a drilling stroke is controlled by the drilling hydraulic cylinder through a pulley block; the drilling hydraulic cylinder is laid out relatively flexibly; the equipment layout space is optimized; the drilling component has a greater ascent and descent space fundamentally; the drilling stroke is prolonged; the drilling movement frequency is reduced, so that the drilling construction efficiency is improved; in addition, due to the optimization, the equipment layout space can be made full use of, so that the driller is compact in structure; with the adoption of a hydraulic driving structure and electrohydraulic control, a stepless speed regulation function is realized, and the driller can meet the drilling requirements of different stratums; a power head is driven by a hydraulic motor and can be combined with mechanical speed reduction, the power transmission reliability is improved further, and the adjustable scope of torque variation is wider; and when the equipment is in use, the labor intensity is reduced, the use cost and labor cost are saved, and the driller can be used for engineering pile hole construction and meets the technological requirements.

Description

Technical field

[0001] The invention relates to an engineering machine, in particular to a hydraulic engineering drilling rig. Background technique

[0002] Engineering drilling rigs are used for large-diameter cast-in-place pile construction in electric power construction, bridges, high-rise buildings, dams, ports and wharfs.

[0003] In the prior art, the traditional mechanical circulation drilling rig uses a motor or an internal combustion engine as a power source, drives a transmission or a reducer, and then switches the transmission shaft through a commutator to realize the power of the power head of the drilling rig or the power of the coiling field respectively. One type of circulating drilling rig power head transmission and hoisting and hoisting transmission are each equipped with a transmission system. The chuck of the power head is arranged above or below the main shaft of the power head, and the main drill rod is installed in the square hole or hexagonal hole of the ch...
