Abstract
The present invention relates to a device for drilling a conical area in the innermost part of a previous drilled cylindrical hole. The invention provides a safe and durable fastening for screws and bolts. The device is suitable for drilling in concrete, rocks and other solid materials.
Description
The present invention relates to a kind of device that is used for getting out conical area in pre-drilled cylindrical hole bottom.This device is used in particular for the boring on concrete, rock, stone and other sturdy material.Apparatus of the present invention can be taper bolt and provide firm grappling in the bottom of boring.
Be known that in the past in the bottom of boring to shape a certain specific conicity value, and this taper value can be machined by various device and auger.One big defective of these methods is that it is too complicated and usually can not obtain gratifying effect, in this external boring procedure, does not have compressed air or hole flushing liquid to supply in the boring.Caused drilling cuttings to remain in the inner end in hole like this, and have to conical area bore good back rely on other method for example compressed air it is got rid of.Different with these known methods, apparatus of the present invention guarantee that compressed air is introduced into, so that get rid of drilling cuttings when boring.
The present invention is based on the following fact, promptly on rock, stone, concrete and similar stiff materials, be difficult to set up reliable and firm anchor point usually.Consequently on these materials, generally can only be drilled to columniform hole for set bolt and screw.In other words, such bolt is only kept by the frictional force between bolt and the columniform straight wall.
Use apparatus of the present invention to bore a conical area, provide more reliable and firm grappling in the inner end of boring in the bottom in columniform hole.
The various distinct methods that bore round taper hole once were described in the past.EP 704 226 is especially at holing on the veneer brick.DE 2 415 240 has described a kind of method and apparatus that bores round taper hole.US 5 829 925 describes a kind of auger that has cutter sweep endways, and this device relies on the hole flushing liquid of pressurization that it is extruded.US 4 978 258 is used to bore cavity and has the drilling tool that can turn round outer pendulum drill bit at a kind of.
The present invention relates to a kind of pre-drilled cylindrical hole bottom that is used on rock, stone, concrete, fragment of brick or other drillable material and get out conical area so that the device of hold-down screw and breaker bolt, this device is characterised in that and comprises a removable drill bit that is connected with the taper joint of turning round outer pendulum that has elastic O-ring, wherein globe joint is connected on the drill bit by through bolt, wherein drill bit, through bolt, all promising introducing compressed air of ballhead that has taper joint or hole flushing liquid and discharge the through hole that runs through of drilling cuttings.
Because the through hole of all promising introducing compressed air or hole flushing liquid in drill bit and taper joint, even be in any angle when taper joint, whenever all do not have drilling cuttings, rock dust and other bulk materials in the boring.
When being processed to form conical area, big power must be applied on the actual drill bit with powerful form of blowing spray and rotation when processing macropore in rock and in the bottom, hole.Apparatus of the present invention are made of globe joint, wherein should bear the impact force that is applied in by actual spheroid, and a firm through bolt bears revolving force.
By the following drawings, describe the present invention more in detail:
Fig. 1 is the sectional drawing that has globe joint and can turn round the whole drill bit of outer taper joint of putting.
Fig. 2 is the side view cutaway drawing of taper joint.
Fig. 3 is the vertical view of drill bit.
Fig. 4 is the traditional rock drill bit view at foot of hole.
Fig. 5 is the view of taper joint of the present invention when burr-drill shape base apertures.
Fig. 6 hammered into shape into and the exemplary plot of fixing taper bolt.
Shown in Fig. 1,2 and 3, drill bit 1 is tightened onto on the drilling rod by its threaded portion 3.Stressed outer pendulum and the taper joint 2 that is drilled to bellmouth is connected by through bolt 4.Bolt 4 has hollow region 14 in central authorities, so that compressed air can both be passed through when taper joint 2 is in any position.Carbide alloy section 5 is installed in the side in the face of the taper joint 2 of boring.These will guarantee more fast and effeciently to get out conical area, and make auger more durable.Be used to introduce compressed-air actuated central passage 11 and 13 and pass drill bit and taper joint 2.There is hollow region 12 in zone between taper joint 2 and drill bit, even the effect in this zone is also can guarantee compressed-air actuated clear passage when taper joint 2 during at extreme position.In Fig. 1, the bottom of dotted line 9 expression borings, the conical area that dotted line 8 expressions will be drilled to.Rubber o-ring 15 is installed in the top of taper joint, and its effect is to force taper joint 2 to get back to its initial position after boring finishes.The lower limb of taper joint 2 bevel 6 cavettos.When taper joint 2 reaches the position that will hole, this taper joint rests in the following of drill bit and only stops on the limit 10.This stops the maximum deflection that taper joint is guaranteed on the limit like this.
Shown in Figure 3 is drill bit 1 and the vertical view that has the taper joint 2 of carbide alloy section 5.Through bolt 4 is illustrated by the broken lines, and provides taper joint 2 to be connected with the revolution of drill bit.
Shown in Figure 4 is the traditional rock drill bit 16 that bores cylindrical hole in rock 17.Boring is performed until till the hole depth 9 that reaches predetermined.
Fig. 5 shows the boring among Fig. 4, but the bellmouth 8 that difference is mounted in the taper joint 2 on the drill bit and has been drilled in the bottom in hole.Because the following bevel 6 of taper joint, bellmouth 8 is put and be drilled to taper joint outside drill bit rotation and hammer action lower stress.The revolution range of tapering part is limited when only stopping limit 10 under it is run into.After bellmouth was drilled to, the rotation and the hammering of drill bit stopped.At this moment rubber o-ring 15 forces taper joint to get back to its initial position, makes integral body extract out from the hole.Drilling cuttings has been compressed air and has discharged from the hole.
The example of the taper bolt 18 that shown in Figure 6 is inserts in the hole.Pipe 19 is placed on the peripheral of taper bolt 18 subsequently and is knocked at the bottom of the hole.Because stressed effect in the hammering process, pipe 19 tapering parts because of bolt 18 are forced outwardly and fill surrounding space.Fixing and anchoring system as safe as a house so just is provided.
The diameter of taper joint, length and angle can change according to preliminary dimension.
Whole drill bit and cone joint preferentially use the extraordinary screw thread of standard.The threaded engagement of using on they and the drilling rod is used for the boring on rock, stone, concrete and other similar material, so that rock breaker bolt and other fastening devices fixing and that grappling is common.By using special standard thread, drill bit and cone joint can be changed fast.
