Description

Drilling-out machine for concrete core

The utility model belongs to the facility that drill through mine working jetcrete layer sample core.

In the shaft and drift supporting process, extensively adopt the jetcrete construction at present.But its workmanship can't detect and control as concrete spray coating thickness and intensity, wants the Control Engineering quality and must drill through layer of concrete core sample.But the domestic and international still useless facility that drill through concrete core sample in mine working.The GZ-1120 type diamond drill that second machine tool accessories factory, China Yantai produces, because complex structure weight is big and adopt the road wheel structure and move very inconveniently in mine working, and the motor that uses flame proof not can not be worked in flammable explosive environments.These rig drilling tool centers and stretching column axis offset distance are bigger, wait of connecting link causes the clamping force of column big more, vibrate easily when creeping into, their drilling directions are adjusted inconvenient, in vertical plane, can not change the position apace, use is restricted, the difficult instructions for use of satisfying mine working.

The purpose of this utility model provides a kind of new facility that can be used for drilling through under the flammable explosive environments of mine working the concrete core.

Superposed two is main guide rail 7, and two that are positioned at the bottom is to pay guide rail 9, and their two ends are separately fixed on front fishplate bar 47 and the rear fishplate bar 48, and the line at main guide rail 7, pair connecting hole center of guide rail 9 on front fishplate bar 47 rear fishplate bars 48 is rectangular. Explosion separation motor 1 is connected on main guide rail 7 and pair guide rail 9 by the motor support base 12,13 that is enclosed within on the fuselage. Motor support base 12, the 13rd has the circulus of blind hole, and said blind hole is stuck on the fuselage of motor 1 just. Motor support base 13 is enclosed within explosion separation motor 1 middle part, two main guide rails 7 pass from its underpart, and adopt the mode that is slidingly connected with motor support base 13, motor support base 12 is enclosed within explosion separation motor 1 front portion, two main guide rails 7 and two pairs of guide rails 9 pass from its edge, and adopt the mode that is slidingly connected with motor support base 12. Explosion separation motor 1 rear portion is connected with tooth bar 15, and tooth bar 15 puts in gear-box 16, the namely rear fishplate bar 48 of gear-box 16 front aprons. Screw thread is arranged at tooth bar 15 tops, and this screw thread gear striped in gear-box 16 lucky and that handwheel 14 drives matches. Rotate handwheel 14, can move forward and backward by gear driven tooth bar 15. The motor front end has drive link 8, is loaded in explosion separation motor 1 rotating shaft. Drill through with transmission power.

Screw thread on the rear tube 21 is directly connected in gear-box 16 rear portions. In rear tube 21 internal sleeve telescoping tube 24 and reserve telescoping tube 25 are arranged, can connect some sections reserve telescoping tubes 25 at telescoping tube 24 according to operating position. At rear tube 21 clamp nut 22 that available handle 23 rotates is housed, by regulating handle 23, can promote telescoping tube 24 and move by the screw thread of clamp nut 22 inboards and the screw thread transmission power in telescoping tube 24 outsides, the utility model all can be held out against in roadway under different situations.

Preceding fishplate bar 47 front portions on balladeur train 4 are by the preceding junction surface 3 that is threaded, before its shell, take over 46 and be provided with preceding top 43 foremost, outer rim is equipped with the dash bowl, in preceding adapter 46, water jacket 45 is housed, water jacket 45 front ends are equipped with drilling tool 2, the rear end is connected to drive link 8, and drive link 8 is sold pin joint with water jacket 45 by pegging graft.Said water jacket 45 is drilling tool center water supply installations, and it can supply cooling water to drilling tool 2, and rock dust is gone out outside the hole.Water jacket 45 is by rotation mandrel 26.Non-rotary water jacket body 29 in outermost end reaches seal water-sealing circle 28 and 27,31 compositions of end cap that play water proof and swivel bearing effect between the two.End cap 27 and water jacket body 29 connecting threads are left-handed, and end cap 28 and water jacket body 29 connection screw threads are dextrorotation.Said rotation mandrel 26 is a hollow, is an end opening taper hole shape, has side opening so that water inlet at the taper hole sidewall.In the end-grain cutting of taper hole opening the mounting or dismounting groove at two 45 ° of oblique angles is arranged, be used to connect drilling tool.Drilling tool is hollow tube-shape, front outer is equipped with diamond drill, be provided with in its back-end and bore tail 49, boring tail 49 is the bullet of the band mounting or dismounting pin of inner hollow, the bellmouth inner wall shape of this bullet shape and water jacket rotation mandrel 26 openends matches, when boring tail 49 and insert, the mounting or dismounting pin that bores tail 49 sticks into water jacket 45 mounting or dismounting grooves, and with rotation mandrel 26 inwall tight connectings and water-tight.

Support 6 is housed under balladeur train 4, and balladeur train 4 is paid balladeur train 10 two ends and is enclosed within on pair guide rail 9, and adopt the mode of being slidingly connected with it on support 6 by paying 10 of balladeur trains, pays balladeur train 10 middle parts and is connected on the support 6 by bent sub 19.Said bent sub 19 lower ends are a short column body, and its inserts leading screw 35 tops of hollow, and free to rotate, when selected when drilling through direction, then by lock-screw 34 lockings.Said support 6 has a pedestal 39 and hinge knot 38, three supporting legs 38 of three supporting legs thereon to regulate its opening angle with screw 40, to change the bearing height and the Area of bearing of support 6.Rotating handwheel 37 can make bevel gear 36 and 41 rotate.Bevel gear 41 inner hole walls also are the groove tight connecting of helical structure and leading screw 35.Rotation handwheel 37 can drive leading screw 35 and move up and down.

When this machine of erecting, drilling tool 2 is withstood on desire the sample position, regulating handle 23 stretches out telescoping tube 24, and the brill tail is held out against in the tunnel, can utilize this moment the utility model to implement drilling operation.Open explosion separation motor 1, driving drive link 8 rotates, the rotation mandrel 26 of water jacket 45 also rotates with drive link 8, and by driving the drilling tool rotation with the pin joint that bores tail 49, rotate handwheel 14 simultaneously explosion separation motor 1 is moved forward, by drive link 8, water jacket mandrel 26 makes drilling tool 1 obtain the power of vertically creeping into, drilling tool is advanced, obtain core.The water jacket body 29 that connects together with water pipe head 30 does not rotate, and from water pipe head 30 water inlets, water enters in it from the side opening of rotation mandrel 29 when creeping into.Because the effect of end cap 27,31 and sealing ring 28, water can not overflow between water jacket body 29 and mandrel 26.Since water jacket mandrel 26 inwalls with bore tail 49 tight connectings, water also can not overflow from their junction, all enters drilling tool 2, water for cooling and take away rock dust after flow away from outlet pipe 50, to guarantee safety, to creep into rapidly.

The utility model provides a kind of new facility that can be used for drilling through in the flammable explosive environments in down-hole, mine the concrete core, it compare with similar machine in the past have flame proof, light, flexible, combination and distortion is convenient, function adaptability reaches characteristics such as global face creeps into by force.And can implement the core sampling in any place of underworkings, satisfy the needs of the construction quality of evaluation sprayed mortar.
