Abstract
A swing mechanism of a rotary drilling rig belongs to the technical field of engineering drilling rig equipment, solving the technical problem that a swing mechanism of a rotary drilling rig with simple structure capable of swinging with 360 DEG. The swing mechanism has the following scheme that a current collector is fixedly installed on the supported beam of the tracked chassis of the rotary drilling rig, the current collector is positioned at the center of a pivoting support, both an external power line and a walking motor power line are connected with the current collector, and the external power line is switched in from the tracked chassis below the center of the pivoting support. The structure is used and both the external power line and the walking motor power line are connected with the current collector through switching of the tracked chassis below the center of the pivoting support so that the rotary drilling rig is not limited by the external power line when swinging so as to realize omnidirectional swing; and the braking motor of the swing mechanism is replaced into normal motor hydraulic brake structure so that the swing braking is stable and the impact load is greatly reduced. The swing mechanism has the advantages of simple structure, low cost, easy production, durability and convenient maintenance.
Description
Technical field
This patent relates to a kind of slew gear of turn digging dynamoelectric drilling machine, belongs to the engineering driller equipment technical field.
Background technology
Rotary drilling rig is a kind of heavy caliber deep hole pore-forming equipment, mainly contains two kinds of forms of all-hydraulic rotary drilling rig and turn digging dynamoelectric drilling machine, and all-hydraulic rotary drilling rig is light and handy flexibly, hole forming method is simple, efficiency of construction is high, but costs an arm and a leg.And the turn digging dynamoelectric drilling machine price is lower, can be again owing to have certain gap on the lower and all-hydraulic rotary drilling rig performance of efficient.
Finding that in working practice existing turn digging dynamoelectric drilling machine can not comprehensively turn round, is to cause the main cause that efficiency of construction is low, labor strength is big.Its reason is that the power supply power supply will be arranged during turn digging dynamoelectric drilling machine work, because power line is imported from upper mounting plate, little, the slow motion of the native scope of getting rid of of rig is caused in the angle of revolution of having limited upper mounting plate, and efficiency of construction is reduced greatly.Also to someone nurse main power line, increase danger, also increase working strength of workers.Original in addition turn digging dynamoelectric drilling machine adopts braking motor to drive revolution, and its braking impact load is big, also is starved of perfect.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the slew gear of a kind of processing and manufacturing simple in structure, easy and assembling production, low cost of manufacture, superior performance, 360 ° of rotating rotary drilling rigs of energy is provided.
The technical scheme that solves the problems of the technologies described above is:
A kind of slew gear of rotary drilling rig, its pivoting support is installed on the crawler body, drilling machine platform is installed on the pivoting support, its improvements are, on the brace summer of crawler body, fixedly mounted a current-collector, current-collector is positioned at the center of pivoting support, and circumscripted power line all is connected with current-collector with the movable motor power line, and circumscripted power line inserts from the crawler body of pivoting support central lower.
The slew gear of above-mentioned rotary drilling rig, the middle part of described drilling machine platform is equipped with rotary reducer, reductor top is equipped with shaft coupling, the liquid braking device of motor, band brake wheel, and the output shaft of reductor bottom connects pinion, and pinion is meshed with the gear of pivoting support outer ring.
The slew gear of above-mentioned rotary drilling rig, described current-collector is made up of shell, dial, current collection slip ring, brush, prap, insulating slab, circumscripted power line is connected on the prap by the crawler body via hole, prap is fixed on the shell by insulating slab, wire to terminal is in brush, brush is fixed on the shell by fixed mount, the current collection slip ring is fixed on the shell by bearing box, in connect the mesopore of cable by the current collection slip ring and be wired on the slip ring prap, the current collection slip ring is fixed on the drilling machine platform by dial again.
Adopt the slew gear of the rotary drilling rig of this structure, circumscripted power line all is connected with current-collector by the crawler body access of pivoting support central lower with the movable motor power line, not limited by circumscripted power line when making the drilling machine platform revolution, has realized comprehensive revolution; The braking motor of slew gear is replaced by common electric machine adds the liquid braking device structure, make rotary braking steady, reduce impact load greatly.The utility model is simple in structure, cost is low, and tissue is produced easily, also has advantage durable, that be convenient to keep in repair, can reduce investment outlay for the user, good economic benefit is not only arranged, and social benefit is arranged.
