Abstract

The invention relates to a bidirectional cement-soil mixing pile machine, which comprises a power source, a transmission mechanism, a bit body and a frame, and is characterized in that the power source comprises a single motor and a reducer which are in mechanical connection in turn, a motor flange, a coupling and a grout injection connector, and the single motor and the reducer are hoisted on the frame; the transmission mechanism comprises a gear box, a main shaft vertically arranged in the gear box, a half shaft sleeved on the lower part of the main shaft, an external sleeve shaft sleeved outside of the half shaft, and a left intermediate shaft and a right intermediate shaft parallel to the main shaft; and the bit body comprises an inner shaft, an inner bit and an outer bit. The pile machine only adopts one motor to drive, uses structural characteristics of gear transmission and kinematic principle, realizes the diversion and mergence of transmission speed and routes and the change of rotation direction, and realizes the bidirectional rotation cement-soil mixing function.

Description

technical field [0001] The invention relates to mechanical equipment in the field of civil engineering, in particular to a two-way cement-soil concrete pile drilling rig driven by a single power. Background technique [0002] At present, the two-way (rotary) cement-soil concrete pile drilling rig used in the field of civil engineering, its two-way rotation mechanism is generally realized by dual motor drive, that is to say, one motor is responsible for driving the inner drill pipe to rotate, and the other motor is responsible for driving the outer drill pipe. rotate. For example, the equipment with the title of invention "two-way cement-soil mixing pile driver (200410065861.4)" has just used dual motors. The pile driver uses dual motors, which are bulky, complex in structure, long in transmission route, high in manufacturing precision requirements, unfavorable for installation, and require motorized lubrication, adding a lubricating oil pump; especially the dual motors have...
