Abstract
The invention provides a power head drive device of a rotary drilling rig. The device can achieve high-speed soil throwing. The rotation speed of a power head can reach 70 rpm. High-speed soil throwing of the power head can be achieved without the need of a two-gear even three-gear speed reducer of an abroad rotary drilling jig or a third high-speed soil throwing motor. According to the power head drive device, a low-speed large-torque-variable motor and a first-stage planetary speed reducer are adopted to achieve high-speed soil throwing, and the power head drive device comprises a low-speed large-torque-variable motor assembly, a first-stage planetary speed reducer assembly and a power head body assembly. The low-speed large-torque-variable motor assembly is connected with the first-stage planetary speed reducer assembly through a spline flange, the first-stage planetary speed reducer assembly is connected with the power head body assembly through a spline flange, the power head body assembly is connected with a drill pipe, and the drill pipe is connected with a drilling tool. The low-speed motor drives the speed reducer, then the speed reducer drives the power head to rotate, and the power head finally transmits torque and rotation speed to the drill pipe. The drill pipe transmits the torque to the drilling tool on the lower portion of the drill pipe.
Description
Technical field
The invention belongs to piling machinery technical field, particularly rotary digging drill power head drive unit.
Background technology
Rotary drilling rig is the principal works machinery of bored pile construction in building foundation engineering, and its advantage is that rotary drilling rig installed power is large, output torque is large, hole quality is good, flexible and convenient operation, efficiency of construction are high, noise is little, environment pollution is little.And coordinate different drilling tools, rotary drilling rig can adapt to the geological conditions of China's most area.During rotary drilling rig work, driving force and the plus-pressure of drilling rod all derive from unit head, and thus rotary digging drill power head is the core component of rotary drilling rig, and the performance of rotary digging drill power head and feature often determine the functional performance of rotary drilling rig.
Rotary digging drill power head domestic at present adopts high speed variable displacement motor assembly and two-stage planetary reducer assembly to drive.Rotating speed due to unit head is limited to the factor of motor, reductor and unit head itself, and when ensureing enough moments of torsion, the maximal rate of unit head is all within 40rpm.
Along with domestic market requires more and more higher to the compliance of the various operating modes of rotary drilling rig, higher requirement is proposed to the range of speeds of rotary digging drill power head, particularly on the small-sized drill of building construction, workshop building etc., require that unit head rotating speed is up to 60rpm, after unit head rotating speed height, to get rid of soil easier for rotary drilling rig drilling tool.In the middle of external prior art, more than 60rpm is realized in order to realize unit head rotating speed, what rotary drilling rig generally adopted is high speed variable displacement motor assembly and two grades even third gear reductor or increase third high speed and get rid of native motor and realize power head height rotating speed and get rid of soil, but such shortcoming is the structure of reductor and controls and power head structure complexity, thus easily breaks down.
Summary of the invention
The invention provides a kind of rotary digging drill power head drive unit realizing getting rid of at a high speed soil, it is characterized in that: comprise low-speed big variable displacement motor assembly, primary planet reductor assembly and unit head body assembly, described low-speed big variable displacement motor assembly is connected with primary planet reductor assembly by spline flange; Described primary planet reductor assembly adopts primary planet transmission; Described primary planet reductor assembly is connected with unit head body assembly by spline flange; Described low-speed big variable displacement motor assembly drives primary planet reductor assembly, and described primary planet reductor assembly drives unit head body assembly to rotate; Described unit head body assembly drives drilling rod, and drilling rod is connected with drilling tool.
Preferably, described low-speed big variable displacement motor assembly comprises low-speed big two-stage variable displacement motor or low-speed big stepless variable motor.
Preferably, described low-speed big two-stage variable displacement motor and low-speed big stepless variable motor are hydraulic motor.
Preferably, described unit head body assembly connects one or more groups low-speed big variable displacement motor assembly and primary planet reductor assembly.
The invention has the beneficial effects as follows: the combination of low-speed big variable displacement motor assembly and primary planet reductor assembly drives unit head body assembly, compare the structure of high speed variable displacement motor assembly and two-stage planetary reducer assembly, enough moments of torsion can be ensured, primary planet reductor assembly is simpler than two-stage planetary reducer structure simultaneously, not easily breaks down; And low-speed big variable displacement motor assembly and the primary planet reductor assembly of many groups can be used, drive unit head body assembly, thus ensureing on the basis that moment of torsion is enough large, unit head rotating speed is enable to maintain 70rpm, giving full play to the efficiency of rotary drilling rig when getting rid of at a high speed soil, improving rotary drilling rig operating efficiency.
