Abstract
The present invention discloses a mining full hydraulic drill linkage hydraulic clamp fastener which comprises a clamp fastener body. The clamp fastener body comprises a left clamping device and right clamping device which are connected by a pull rod structure and a reinforcement oil cylinder which is arranged in the right clamping device. Compared with the traditional clamp fastener, the clamp fastener is provided with two oil cylinders which push a clamping disc spring open at the same time, and the clamp fastener can be released by less pressure, thereby being good for opening the clamp fastener by the rotation back pressure of the drill and facilitating the drill rotation-propulsion and clamp fastener linkage operation. The clamp fastener can not only use a belleville spring to clamp the a drill rod, but also couple a drill power head driving motor reverse oil passage in the reinforcement oil cylinder and utilize the reverse pressure of the drill to realize reinforcement fastening motion, thus ensuring the reliability of the fastening motion of the drill rod; the clamp fastener is also provided with an automatic float centering structure which can follow the drill rod to center the fastening motion automatically and ensure the operation precision.
Description
Technical field
The present invention relates to a kind of hydraulic pressure chucking device of all-hydraulic drill, particularly a kind of linkage hydraulic clamper for mining fully hydraulic rig of normally closed clamping.
Background technology
Hydraulic gripper at present commonly used can be divided into normally closed type and two kinds open in usual by the state of its slips when not working.
The normally closed type clamper unclamps by spring clamping, oil cylinder, the size of its clamping force depends on the tension force that spring produces, for guaranteeing enough clamping forces, need big specification or more spring, when unclamping clamper, need further compression spring, therefore need the oil cylinder of the big section of configuration or improve opening pressure to produce bigger thrust, so just caused the physical dimension of clamper to increase, in the hydraulic system that the interlock function is arranged, the opening pressure raising can cause efficient to reduce.
Clamper open in usual clamps with oil cylinder, and spring unclamps, and clamper open in usual is more simple in structure than normally closed type clamper, but its maximum shortcoming is when the oil pressure that breaks down disappears, clamping force also disappears at once, and therefore, it only suits to use creeping on the rig of nearly horizontal drilling.
Hydraulic gripper is as one of main executing agency of all-hydraulic drill, to the basic demand of its proposition is when the clamping drilling rod, action is wanted rapidly, and enough clamping forces are arranged, but present clamper does not have the setting of other boosting oil cylinder because slips can only be once afterburning by oil cylinder, makes that the frictional force between the slips is less, thereby cause clamping unreliable, security incident easily takes place; Need bigger external force when opening clamper in addition, make that not only structure is more complicated, also be unfavorable for the rotation-propelling and the clamper interlock of rig.

The course of work of the present invention is as follows:
(1) clamps the drilling rod operation
The present invention is the linkage hydraulic clamper for mining fully hydraulic rig of normally closed clamping, and when clamping 2 normally closed clamping of butterfly spring, clamping butterfly spring 2 left ends unclamp cylinder body 4, right slip spider 7, the right side and unclamp piston 8 to left movement by compressing left end cap 1 and driving a left side; Clamp butterfly spring 2 right-hand members and unclamp by compressing a left side that piston 3, left slip spider 5, the right side unclamp cylinder body 9, thereby right end cap 11 moves right and clamps drilling rod.
When reinforcement clamps, oil-in III 17 oil-feeds, fluid acts on reinforcement piston 10 right sides, and the reinforcement piston moves to left, and drives the right side and unclamps piston 8, right slip spider 7, a left side and unclamp cylinder body 4, left end cap 1 to left movement; Simultaneously fluid acts on the left side of right end cap 11 and drives right end cap 11, the right side and unclamps cylinder body 9, left slip spider 5, a left side and unclamp piston 3 and move right, thereby reinforcement clamps drilling rod.
(2) unclamp the drilling rod operation
As oil-in I 15 and oil-in II16 with when feeding pressure oil, hydraulic oil enters by a left side and unclamps piston 3, and a left side unclamps that oil cylinder is unclamped on a left side that cylinder body 4 forms and piston 8 is unclamped on the right side, and the right side is unclamped the right side that cylinder body 9 forms and unclamped in the oil cylinder.
When entering pressure oil in oil cylinder is unclamped on a left side, pressure oil acts on a left side and unclamps piston right-hand member 3, drives a left side and unclamps that piston 3, left slip spider 5, the right side unclamp cylinder body 9, right end cap 11 is moved to the left; Simultaneously pressure oil acts on the right-hand member that cylinder body 4 is unclamped on a left side, drives left end cap 1, a left side and unclamps cylinder body 4, right slip spider 7, the right side and unclamp piston 8 and move right, and a left side is unclamped oil cylinder compression butterfly spring and unclamped drilling rod simultaneously.
In like manner as can be known, when the oil cylinder oil-feed was unclamped on the right side, the compression butterfly spring also unclamped drilling rod;
During practical application, about unclamp oil cylinder oil-feed simultaneously, compress butterfly spring simultaneously, so only the less system pressure of need just can unclamp clamper.The system pressure that helps rig when interlock rotation and produced when advancing unclamps clamper.
Common hydraulic gripper is when rig is worked, thereby the hole of being bored may crooked make drill pipe buckling depart from the chuck of rig center, and clamper of the present invention has unsteady self-centering structure, when the clamp holder clamping drilling rod, the active force that produces when slips touches drilling rod can drive the clamper body and slide on the guide rail of base, make the center of clamper aim at the drilling rod center all the time, follow the effect that the drilling rod self-centering clamps, guaranteed performance accuracy thereby arrive.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present invention.
