Description

Vibrating hammer with hidden holes

The utility model relates to a kind of Geological Engineering equipment that carries out the heavy caliber drilling and forming hole in solid rock.

The heavy-caliber base rock drilling method has three kinds at present:

1, gear wheel or roller cutter bit creep into, and when at shallow bore hole, because the pressure of the drill deficiency, efficient is very low.

2, chilled shot drilling, its defective are that shot-drilling can run off when there are crack, solution cavity in bedrock surface injustice or rock stratum; If ring-type is crept into the taking-up core of still needing.

3, the pneumatic or hydraulic impacter of down-the-hole creeps into.Domesticly can't produce the heavy caliber down-the-hole air hammer at present.U.S. Ying Gesuo--heavy caliber super (SuperDrill) the down-the-hole hammer that blue (Ingersoil--Rand) company produces bores the footpath and also has only 762mm.But in the cluster type heavy caliber down-the-hole that the said firm the produces hammer maximum a kind of hole diameter be 1016mm 1..The defective that down-the-hole air hammer creeps into is that the aperture is still big inadequately, does not satisfy heavy caliber and creeps into needs as bored pile and FIX CHARGE RATE ABOUT THE WASTE water hole pore-forming.

The heavy caliber that carries out solid rock creeps into, and does not also have a kind of good method and apparatus at present.

The purpose of this utility model just provides a kind of new drilling machine operating principle--down-the-hole mechanical shock.It is characterized in that utilizing vibrating hammer that drill bit is carried out mechanical shock, realize that impact rotating creeps into.Rig by this principle design is the down-the-hole vibrating hammer.

Below with reference to accompanying drawing the utility model is done detailed description.

Fig. 1 is a schematic diagram of mechanism of the present utility model.

Fig. 2 is the vibrating bin schematic diagram of mechanism.

Fig. 3 is that axle moves the coupler structure schematic diagram.

Fig. 4 is the rack construction schematic diagram.

Fig. 5 is the hammehead structure schematic diagram.

Fig. 6 is the utility model working condition figure.

With reference to Fig. 1, this equipment comprises following system:

1, dynamical system: (2) are cable socket, and cable (5) connects vertical deluge proof motor (6), and motor power reaches rotary system by shaft coupling (8) and conical gear (9); The power of motor also moves shaft coupling (10) and conical gear (11) by axle, drives vibrating bin gear (12).

2, impact system: a pair of or several externally-engaged cylindrical gears (14) that (among the figure for a pair of) number of teeth is equated are arranged in the vibrating bin (13), the eccentric block (15) that quality equates is housed in the equal riveting in the both sides of each gear.The synchronous backward revolution of eccentric block makes vibrating bin produce vertical vibration.With Bolt Connection worm gear seat (16), worm and wormwheel (17) is installed in the seat in the vibrating bin bottom.Worm gear and hammer stem (18) are formed worm drive, and hammer stem and worm gear seat move up and down hammer stem again for feather key connects only, and can not about turn round.The hammer stem bottom connects tup (19).Open side cover (29), use the box spanner rotary worm, can change tup and last anvil block (22) and reach the gap of anvil block (23) down, realize upwards impact, impact downwards or three kinds of operating modes that make progress repeatedly, impact downwards.Frequency of impact is 15Hz.

3, rotary system: the high rotating speed of motor reaches hollow shaft (31) through jaw clutch (27), roller gear (30) after slowing down by worm and wormwheel (26) again.This hollow shaft is installed in drain pan (24) centre bore together with sliding bearing and rotating seal.Drain pan and urceolus (7) are used bolton, add sealing ring therebetween.Ball tooth drill hammer (25) is installed in the hollow shaft lower end with flange, and drill speed is 10r/min.Open side cover (28), jaw clutch is separated, hollow shaft no longer turns round, and this equipment promptly can be used for the heavy casing that pulls out.

4, the flushing liquor system for the distribution of commodities: water tap (20) is installed in the hollow shaft upper end.Water pipe (21) lower accepting water tap, on connect sebific duct (4).Sebific duct is installed in place, urceolus top center hole with flange.Urceolus top is tapered and have three skylights (by 120 ° of arrangements), and the skylight is sealed with cover plate (3).The effect in skylight is for the sebific duct flange being installed and being connected cable.The urceolus center upper portion is welded the short drill pipe (1) of flanged dish, but above stacks until the aperture.

5, lubricating system: plunger displacement pump is installed on the drain pan, and pull bar is fixed in the vibrating bin outside, utilizes the vibration of vibrating bin, and plunger displacement pump is delivered to several oil sites of highest point with lubrication oil by oil pipe, makes it that drippage is lubricated downwards.Locate the charge of oil chi at side cover (29), check oil mass.

The above urceolus and interior arrangement thereof are the down-the-hole vibrating hammer.

With reference to Fig. 2, the roller gear (14) that a pair of number of teeth equates is installed, in vibrating bin (13) at the equal eccentric block (15) of the both sides of each gear riveting packing quality.

With reference to Fig. 3, last half a coupler (32) has the cross four paws, and a plurality of (among the figure being three) roller (33) is housed in each pawl.The upper end of following half a coupler (34) is a cross hollow shaft in.Under inserting, last half a coupler in the half a coupler, has only the roller contact therebetween.Like this can transfer torque, bigger axial displacement is arranged again, just can satisfy the needs that vibrating bin produces certain amplitude.

With reference to Fig. 4, motor (6) is fixed on frame (35) top.Frame is made up of four upright angle steel and some horizontal strokes, bearing diagonal.Frame and its underpart frame seat (40) use bolton, frame seat to be welded on the drain pan (24).At the bottom of vibrating bin (13) case four case ears (36) are arranged, support with four groups eight cylindroid helical-coil compression springs (37).Spring and guide rod (38) are fixed in the frame by guide rod seat (39).

With reference to Fig. 5, tup is " U " body that seals, and is made up of crossbeam (41) and hammer body (42).Hammer stem (18) is installed at the crossbeam center.The hammer status is a two parts symmetrical, is connected into integral body with screw rod.Hammer body bottom center has a circular hole, and hollow shaft (31) passes thus, this upper end water receiving tap (20).This down-the-hole vibrating hammer is when work, and anvil block (23) is down hit in the lower surface of hammer body bottom, and another side hits goes up anvil block (22).

With reference to Fig. 6, when using this equipment, ball tooth drill hammer (25) is installed in the bottom earlier, stube cable (43) again uses drilling rod (44) with it down at the bottom of hand-hole thereupon.After switching on the pump,, promptly begin to creep into again with the power connection of console (45).The frequency of impact of this equipment and the adjustment of impact force are to realize by the speed governing to motor.The rotating reaction torque of drill bit is then by rotating disk (46) balance of drilling rod by rig.The weight of drilling rod and this equipment acts on the drill bit, promptly forms the axial pressure at the bottom of the hole.

The utility model does not also change owing to urceolus except that can carrying out the suction of direct circulation and pump, gaslift reverse circulation drilling, thereby can be easy to realize pump act reverse circulation drilling.This equipment is applicable to engineering constructions such as geology, building, metallurgy, coal, traffic, water conservancy, military affairs.
