Description
Technical Field
The utility model belongs to the technical field of raise boring machine equipment, especially, a reaming stabilising arrangement for raise boring machine.
Background
The raise boring machine drives the hydraulic motor through the motor of the drilling machine, the hydraulic motor drives the water tap, and transmits torque to the drilling tool system by using hydraulic power to drive the drill rod and the drill bit to rotate, and the hob on the guide hole drill bit or the reamer bit rolls or slides slightly along the working face of the rock at the bottom of the well under the action of drilling pressure. Meanwhile, axial pulling and pressure generated by the oil cylinder of the main engine also act on the pilot hole drill bit or the expanding drill bit through the power head and the drill rod, so that a hob of the pilot hole drill bit rolls under the action of drilling pressure to generate impact load, and hob teeth generate impact, extrusion and shearing actions on rocks to break the rocks.
The broken rock debris is washed by the circulating flushing fluid when the guide hole is drilled, and the rock debris is lifted out of the drill hole by the flushing fluid along the annular space between the drill rod and the hole wall. The guide hole drill bit is dismounted during hole expansion, the reverse expansion hob is installed, rock debris directly falls into a lower horizontal roadway through dead weight, and the rock debris is timely cleaned and conveyed out through a loader and a conveying device. However, the drill rod must withstand both the support force and the rotational torque during the drilling process of the raise boring machine. After the drill rod exceeds a certain length, the drill rod is easy to swing, the accuracy of drilling is affected, and even the drill rod is broken.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides a reaming stabilising arrangement for raise boring machine.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a reaming stabilising arrangement for raise boring machine, includes the drilling rod be equipped with the last antifriction bearing and the lower antifriction bearing that cup joint on the drilling rod upward be equipped with fixed last chuck in the antifriction bearing week be equipped with fixed lower chuck in the antifriction bearing week down, go up the chuck and pass through biax hydraulic telescoping rod with lower chuck the upper surface symmetry of going up the chuck sets up the upper boom staple bolt the lower surface symmetry of chuck sets up down the pole staple bolt down.
Preferably, the upper pole hoops symmetrically arranged and the lower pole hoops symmetrically arranged are connected through fastening bolts.
Preferably, the upper rod hoop and the lower rod hoop are the same in structure and comprise connecting rods, one end of each connecting rod is hinged to the base, and the other end of each connecting rod is connected with the corresponding hoop.
