Abstract
The utility model relates to a drillability-measuring instrument for rock, which belongs to the mechanical device researching the intensity of solid materials and is composed of a transmission mechanism, an impact mechanism, a pressurizing mechanism, a drill bit part, a rock holding barrel, etc. The utility model can be used for simulating an impact drill, an abrasion drill, an attacking abrasion drill to measure the drillability indexes of various rocks. The utility model can also be used for measuring the abrasiveness of the rocks.
Description
The invention belongs to the mechanical hook-up of research solid material intensity.
In drilling engineering,, need to understand the rock drillability size in order to select rational drill bit and technological procedure.The method that the mensuration rock drillability has been used has real statistic law, the indoor drilling machine determination method of boring.Up to the present, also do not have a kind of multi-functional, be applicable to the on-the-spot light instrument that uses.The present invention designs for satisfying these needs.
The present invention mainly is made up of beater mechanism, gear train, pressing mechanism, bit part and rock clamping tube.Beater mechanism comprises adjustable cap (1), spring (2), block stamp (3), hammer ear (4) and guide finger (23).Adjustable cap (1) is being controlled the decrement of spring, thereby is determining the ballistic work of block stamp.Hammer ear (4) and guide finger (23) are positioned at the both sides of block stamp, but not on same straight line.Gear train is a conical gear kinematic train of having utilized the large size hand drill, it comprises driving bevel gear (6), passive conical gear (8) and Connection Block (7), and this mechanism is that drill bit (13) provides gyration and cooperates beater mechanism to produce the percussion action of certain frequency.Pressing mechanism is will to be added on the drill headstock (12) via pressurization disk (10) times over the pressure of counterweight (19) weight by the pulley blocks of being made up of fixed pulley (16,24) and travelling block (17,18).Bit part comprises drill headstock (12) and drill bit (13).Rock clamping tube (14) is fixed on the base (15), and the lower end has liquid flow hole, and three stiff ends of pressurization pulley blocks are fixed on this tube.The center line of clamping tube (14) and the axial line of drill bit have a side-play amount, and it is vertical substantially and parallel that this side-play amount guarantees to walk around the lifting rope that pulley (18) is connected on the clamping tube on the one hand, can make on the other hand that drill bit on rock face more bores several holes.Gear train, beater mechanism, pressing mechanism and bit part are formed the main body of tester, and main body can move along slide (21) is upper and lower by means of slide block (22).
Shake driving gear (6) by handgrip (9), on the one hand, wedge shaped projection on the driving gear edge (5) is by means of hammer ear (4) compression spring on the block stamp, block stamp is upwards pushed away, after the projection, block stamp hits connector (7) under the effect of deadweight and spring, the impact of generation is passed to drill bit via axle (20); On the other hand, driven gear (8) will be passed to drill headstock and drill bit with motion break-in, the speed change of driving gear times over the rotating speed of driving gear via axle, produce gyration.So just realized that the actual impact rotating of simulation creeps into, the headway per drill bit under certain revolution can be used as the rock drillability index.The projection number that changes on gear (6) wheel rim just can obtain different frequency of impact (inferior/as to change).If block stamp is sling, the hammer ear does not contact with projection, does not then have impact, realizes pure rotary drilling.Washing fluid enters drill bit bottom flushing landwaste by the cavity of pressurization disk and the center pit of axle.Pressurization disk still remained static when thrust bearing (11) rotated drill headstock, guaranteed carrying out smoothly of compression motion.
This tester volume is little, in light weight, and it can simulate abrasion drill, reciprocating drill and mace bit, determines all kinds of rock drillabilities, can also measure the abrasive property of rock with blank matrix drill bits.
The drilling speed that adopts mace bit to creep into grouan at situ of drilling well be 2.4 meters/time, it is 4.6 that analyzer is measured the drillability index; Creep into quartzitic drilling speed and be 0.84 meter/time, the drillability index of mensuration is 2.25.This shows that the index of measuring with the drillability analyzer can reflect the complexity of actual rock drilling.The drillability index can check in by table or curve.
Claims (6)
1, a kind of rock drillability analyzer, it has a conical gear break-in variable transmission mechanism, it is characterized in that the top assembling spring block stamp beater mechanism of gear train, bottom assembling pulley pressing mechanism and frame of the bit have a rock clamping tube to be fixed on the base of frame of the bit below.
2, according to the described analyzer of claim 1, it is characterized in that some projections are installed on the driving bevel gear wheel rim of gear train, guarantee certain frequency of impact.
3, according to the described analyzer of claim 1, it is characterized in that having adopted the pulley pressing mechanism, the pressurization rope is walked around a pair of pulley that is installed on the pressurization disk, will be added on the drill headstock times over the pressure of counterweight weight by means of moving fixed pulley group.
4, according to the described analyzer of claim 1, it is characterized in that having on the block stamp hammer ear and a guide finger, hammer ear and guide finger are assemblied in the block stamp both sides, but not point-blank.
5, according to the described analyzer of claim 1, it is characterized in that having a rock clamping tube, the revolution axial line of this center line and drill bit has a side-play amount.
6,, it is characterized in that the tester main part of being made up of gear train, beater mechanism, pressing mechanism and frame of the bit can move up and down along slide by slide block according to the described analyzer of claim 1.
