Abstract
This patent relates to a kind of rotary drilling rig, belongs to engineering machinery.The technical solution adopted in the utility model is: rotary drilling rig, comprise crawler type vehicle body and mast, also comprise dynamical system, the drilling rod driving-disc of gear drive is established in the bottom of mast, the output shaft of dynamical system connects the power shaft of reductor by the driving shaft being provided with universal joint, the output shaft of reductor is connected with the driven wheel of drilling rod driving-disc, vehicle body end establishes the hoist engine with clutch, wire rope on hoist engine is walked around mast top and is hung drilling rod, the drill bit of drilling rod is through drilling rod driving-disc, and drilling rod driving-disc drives drilling rod to rotate decline.Dynamical system is diesel engine.The utility model has the advantage of: by power transmission shaft Direct driver drilling rod, avoid the problem that fault rate is high, oil consumption is high of hydraulic control, and convenient for maintaining; Hoist engine inside uses clutch, only needs to unclamp clutch when drilling rod declines, and drilling rod relies on gravity to decline, and fuel-efficient cost is low.
Description
Technical field
This patent relates to a kind of rotary drilling rig, belongs to engineering machinery.
Background technology
Rotary drilling rig is the construction machinery of pore-forming operation in a kind of applicable building foundation engineering.Mainly be suitable for the soil layer constructions such as sand, cohesive soil, slity soil, be used widely in the multiple foundation basic constructions such as castinplace pile, diaphragm wall, underpin.
Such rig generally adopts hydraulic crawler to stretch chassis, the collapsible brill mast of automatic lifting, telescopic drill rod.Complete machine is handled and is generally adopted Hydraulic guide control, load sensing, but hydraulic control exists series of problems, and such as oil consumption is high, and hydraulic fault rate is high, and maintenance cost is high, keeps in repair consumption wealth consuming time; The rotary drilling rig manufacturing cost of hydraulic control own is high, and selling price is high; It is slow that the rotary drilling rig of hydraulic control puts drilling rod speed.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary drilling rig, solves the problem that oil consumption is high, maintenance cost is high, price is high of hydraulic-driven drilling rod.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of rotary drilling rig, comprise crawler type vehicle body and mast, it is characterized in that, also comprise dynamical system, the drilling rod driving-disc of gear drive is established in the bottom of mast, the output shaft of dynamical system connects the power shaft of reductor by the driving shaft being provided with universal joint, the output shaft of reductor is connected with the driven wheel of drilling rod driving-disc, vehicle body end establishes the hoist engine with clutch, wire rope on hoist engine is walked around mast top and is hung drilling rod, the drill bit of drilling rod is through drilling rod driving-disc, and drilling rod driving-disc drives drilling rod to rotate decline.Dynamical system is diesel engine.
The utility model has the advantage of: by power transmission shaft Direct driver drilling rod, avoid the problem that fault rate is high, oil consumption is high of hydraulic control, and convenient for maintaining; Hoist engine inside uses clutch, only needs to unclamp clutch when drilling rod declines, and drilling rod relies on gravity to decline, and fuel-efficient cost is low.

Detailed description of the invention
The utility model as described in Figure 1, dug under controlling to replace with and adopting dynamical system to be rotated by power transmission shaft Direct driver drilling rod by the high hydraulic-driven of fault rate is high, oil consumption.
The utility model structure is as follows: comprise crawler type vehicle body, mast and diesel engine, the drilling rod driving-disc of gear drive is established in the bottom of mast, the output shaft of dynamical system connects the power shaft of reductor by the driving shaft being provided with universal joint, the output shaft of reductor is connected with the driven wheel of drilling rod driving-disc, vehicle body end establishes the hoist engine with clutch, wire rope on hoist engine is walked around mast top and is hung drilling rod, and the drill bit of drilling rod is through drilling rod driving-disc, and drilling rod driving-disc drives drilling rod to rotate decline.
Working method of the present utility model:
Start Diesel Driven hydraulic system to be holded up by mast, drilling rod is sling and is put into drilling rod driving-disc by hoist engine, treats that aligning revolves and digs coordinate, starts under diesel engine drives drilling rod to rotate and digs.
The utility model adopts the hard transmission having power transmission shaft, the hydraulically powered series of problems avoided.
