Description
Technical field
The present invention relates to a kind of engineer geological prospecting equipment, particularly a kind of gantry type rock-core borer.
Background technology
From 2006, State Council promulgated since " decision about enhancing geological work ".China's mining industry is recovered rapidly, and geological core drilling increases fast, and the input of mineral exploration is also corresponding to be continued to increase.Along with progress and the development of society, the demand in market also changes various, so technological development needs constantly innovation, could meet the market demand of development change.Take a broad view of probing market, a feast for the eyes multi-form core prospecting drill.Be nothing but two large types, one is spindle-type core drill, and stable performance is simple to operate, and shortcoming is that to creep into stroke little, and namely the unit head backhaul distance of creeping into, cannot meet the length of a borehole wire-line coring drilling rod; Its two, be the all-hydraulic power head formula rock-core borer grown up in recent years, exploration market also occupy certain share.The sharpest edges of all-hydraulic power head formula rock-core borer are that to creep into stroke long.Namely the unit head backhaul distance of creeping into, can meet the length of a rope coring drill pipe.Creep into for stroke relative to spindle-type core drill, stroke increases about three times, single from this point, substantially increases the drilling efficiency of rig.Its shortcoming is: 1. manufacturing cost is higher, and price is relatively costly, and price is same size, close to a lot of times of the spindle-type core drill price of configuration.Especially, the price of import all-hydraulic power head formula rock-core borer is expensive surprising especially.Its price is the double-digit multiple of spindle-type core drill price.This price, domestic majority is visited troop and is difficult to bear; 2. power loss is large, and oil consumption is large.Due to the torsion pass of all-hydraulic power head formula rock-core borer, drive oil pump by diesel engine, drive motor to pass to unit head by the hydraulic oil of oil pump output to carry out torsion pass, like this, be converted to hydraulic energy by mechanical energy, the process of mechanical energy is converted to again by hydraulic energy, have lost some power, the speed of adding unit head self is smaller, passes to the moment of torsion of drill load end, reach the moment of torsion necessarily bored needed for dark specification, diesel engine power must be strengthened.We take the vertical shaft type of same size drilling ability (referring to the moment of torsion of load end) and the rock-core borer of all-hydraulic power head formula to make comparisons, the torsion pass of spindle-type core drill, that diesel engine directly drives gearbox to slow down by clutch, transfer case slows down and gyrator slows down, the load of rig is passed to through multi-stage speed-reducing, whole system is gear drive, relative power loss is less, system slowdown is than large, load end moment of torsion is larger, the all-hydraulic power head formula rock-core borer of close specification and spindle-type core drill are made comparisons, the aerodynamic power that all-hydraulic power head formula is joined, be the aerodynamic power that spindle-type core drill is joined twice more than, power is invested and power consumes energy, and cost is all higher, 3. under hoist engine, rope speed is slow, the hoist engine of all-hydraulic core drilling rig, hydraulically powered, when drill down operator, the ability of movement of falling object when boring under not possessing drilling tool, relative running speed is slower, and the hoist engine of spindle-type core drill, owing to possessing the ability of the movement of falling object during lower brill, running speed is very fast, and controllability is strong again.Commercially be badly in need of one so existing and can realize all-hydraulic core drilling rig Long travel drilling ability, spindle-type core drill machine driving can be realized again, the rock-core borer of exploration drilling efficiency can be improved.
