In view of the above-mentioned problems of the prior art, the present invention provides a kind of hydraulic drilling rod clamper, its clamping force is strong, easy In replacing, the clamping of plurality of specifications drill string is suitable for.
To achieve these goals, a kind of hydraulic drilling rod clamper that the present invention is used, including clamper housing and arrangement In the hydraulic jack of clamper enclosure interior, left connecting rod, clamper slips, right connecting rod, the left connecting rod and the symmetrical cloth of right connecting rod Put in clamper housing, one end of left connecting rod and one end of right connecting rod are connected by the way of gear engagement, left connecting rod it is another The other end of one end and right connecting rod is connected with clamper housing;Two clamper slips are arranged symmetrically in clamper housing, can The drill rod boring tool of plurality of specifications is clamped, and is separately mounted in left connecting rod and right connecting rod;Two hydraulic jacks are arranged symmetrically in a left side The top of connecting rod and right connecting rod, one end of hydraulic jack is connected with clamper housing, and the other end is connected with left connecting rod or right connecting rod; Engaged by the telescopic drive left connecting rod of hydraulic jack, the gear of right connecting rod two, drive holding dog slips along clamper housing Central axis direction move up and down, realize the clamping or release of drilling rod.
Preferably, the end of the left connecting rod and right connecting rod is provided with through hole, and passes through axle II and clamper housing respectively Connection.
Preferably, in addition to two cylinder supports being symmetrically mounted in clamper housing, hydraulic jack passes through oil cylinder branch Seat is arranged on clamper housing.
Preferably, the cylinder barrel end of the hydraulic jack is arranged on cylinder support, tailpiece of the piston rod by axle I and left connecting rod or The middle part connection of right connecting rod.
Preferably, the both sides at the hydraulic jack cylinder barrel end and the two ends of cylinder support are connected, hydraulic jack cylinder barrel end Both sides are connected to transit joint, plug.
Preferably, the clamper slips be provided with handle, clamper slips can clamp Φ 55mm, Φ 71mm, Φ 89mm, The drill rod boring tool of tetra- kinds of different-diameters of Φ 114mm.
Compared with prior art, the present invention is disposed with hydraulic jack, left and right connecting rod and clamper slips using inside Clamper housing, by the flexible of hydraulic jack, easy realizes the clamping and release of drilling rod.Work as hydraulic cylinder piston When bar stretches out, left connecting rod, right connecting rod will be driven to move downward, so as to promote two clamper slips to close up, by drill-rod clamping;When During hydraulic jack counteragent, left connecting rod, right connecting rod will be driven to move upwards, so that promote two clamper slips to open, will The drilling rod of clamping unclamps.Worked using hydraulic oil as power source drive hydraulic jack, the left and right connecting rod of telescopic drive of hydraulic jack Between engage, drive the motion of two clamper slips, realize pinching action, clamping force is big, and aperture centering is good.Between all parts Connected mode is simple, is conveniently replaceable, its is simple in construction, easy for installation, is suitable for the clamping of plurality of specifications drilling rod.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
Fig. 2 be Fig. 1 in A-A to sectional view;
Fig. 3 is Fig. 1 top view.
In figure:1st, clamper housing, 2, hydraulic jack, 3, left connecting rod, 4, clamper slips, 5, right connecting rod, 6, plug, 7, Cylinder support, 8, axle I, 9, axle II, 10, transit joint.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of hydraulic drilling rod clamper, including clamper housing 1 and it is arranged in clamper housing 1 Hydraulic jack 2, left connecting rod 3, clamper slips 4, the right connecting rod 5 of inside, left connecting rod 3 and right connecting rod 5 are arranged symmetrically in clamper In housing 1, one end of left connecting rod 3 and one end of right connecting rod 5 are connected by the way of gear engagement, the other end of left connecting rod 3 and The other end of right connecting rod 5 is connected with clamper housing 1;Two clamper slips 4 are arranged symmetrically in clamper housing 1, can be pressed from both sides The drill rod boring tool of plurality of specifications is held, and is separately mounted in left connecting rod 3 and right connecting rod 5;Two hydraulic jacks 2 are arranged symmetrically in a left side The top of connecting rod 3 and right connecting rod 5, one end of hydraulic jack 2 is connected with clamper housing 1, the other end and left connecting rod 3 or right connecting rod 5 connections;Engaged by the telescopic drive left connecting rod 3 of hydraulic jack 2,5 liang of gears of right connecting rod, drive the edge of holding dog slips 4 The central axis direction of clamper housing 1 moves up and down, and realizes the clamping or release of drilling rod.Wherein, left connecting rod 3 and right connecting rod 5, two Individual clamper slips 4, two hydraulic jacks 2 are arranged symmetrically in clamper housing 1 along orifice center line.
Preferably, the end of the left connecting rod 3 and right connecting rod 5 is provided with through hole, and passes through axle II9 and clamper shell respectively Body 1 is connected.It is attached by way of this flexible connection of axle, it is ensured that when hydraulic jack 2 stretches, left connecting rod 3 and right company The activity of bar 5, frictional force is small, operation of being more convenient for.
Preferably, two cylinder supports 7 being symmetrically mounted in clamper housing 1 are may also include, hydraulic jack 2 passes through oil Cylinder bearing 7 is arranged on clamper housing 1.With making by other supporting plates or the specific internal structure of clamper housing 1 of setting Hydraulic jack 2 can make its simpler, whole device of connection compared with the method that clamper housing 1 is connected using cylinder support 7 Also it is more stable, it is more convenient for dismounting or adjusts.Left connecting rod 3,5 liang of gears of right connecting rod can be changed by changing various sizes of cylinder support 7 Engagement situation, central axis direction up and down motion amplitude of the change clamper slips 4 along clamper housing 1, it is achieved thereby that more The clamping of specification drilling rod.
Preferably, the cylinder barrel end of the hydraulic jack 2 is arranged on cylinder support 7, and tailpiece of the piston rod passes through axle I8 and left company The middle part connection of bar 3 or right connecting rod 5.Wherein, the both sides at the cylinder barrel end of hydraulic jack 2 are connected with the two ends of cylinder support 7, liquid The both sides at the cylinder barrel end of compressing cylinder 2 are connected to transit joint 10, plug 6.
Preferably, handle can be set on the clamper slips 4, the regulation of manually implemented slip or solid can be passed through Fixed, the clamper slips 4 of use can clamp Φ 55mm, Φ 71mm, Φ 89mm, the drill rod boring tool of tetra- kinds of different-diameters of Φ 114mm.
During work, using hydraulic oil as power source, when the piston rod of hydraulic jack 2 stretches out, left connecting rod 3, right company will be driven Bar 5 is moved downward, so as to promote two clamper slips 4 to close up, by drill-rod clamping;When 2 counteragent of hydraulic jack, by band Dynamic left connecting rod 3, right connecting rod 5 are moved upwards, so as to promote two clamper slips 4 to open, the drilling rod of clamping is unclamped.
From said structure, the present invention is worked using hydraulic oil as power source drive hydraulic jack, and hydraulic jack is stretched Engaged between the left and right connecting rod of contracting driving, drive two clamper slips motions, realize pinching action, clamping force is big, aperture centering It is good.Connected mode between all parts is simple, is conveniently replaceable, its is simple in construction, easy for installation, is suitable for plurality of specifications drilling rod Clamping.
