Abstract
The utility model discloses equipment of an engineering machinery, in particular to a drilling machinery part for geologic drilling or engineering individual-drilling. The utility model has the characteristics that based on the common hydraulic pressure chuck structure, a rotating shaft is sleeved on the inner hole of a spring; and one end of the spring is propped against the inner wall of a spacer sleeve, and the other end of the spring is propped against a sliding bush. The sliding bush is connected with a wedge which is contacted with slips on the inclined plane. The utility model has the advantages of compact structure, light weight, small calorification and high efficiency under the premise of satisfying the large clamping force.
Description
Technical field
The utility model relates to a kind of equipment of engineering machinery, specifically is meant a kind of geological drilling or engineering drilling machine parts of visiting of being used for.
Background technology
Existing rig oild chuck principal mode has: 1, utilize spring tension to clamp drilling rod as power, hydraulic power is unclamped drilling rod; 2, clamp or unclamp drilling rod and all utilize hydraulic power (oil cylinder); 3, utilize hydraulic power to clamp drilling rod, spring tension is that power unclamps drilling rod.
Prior art can meet the demands to solving the oild chuck that needs less clamping force, and just structurally some changes.Under the situation for the very big clamping force of needs, no matter be to adopt spring tension as power, still adopting hydraulic pressure is that power all exists deficiency.For adopting spring tension is the situation of power, and clamping force is big more, and the tension force of must is big more, and it is many that the spring size reaches the spring number greatly, and then structure is huge, implements difficulty; For utilizing hydraulic actuation power to clamp the situation of drilling rod, when adopting the Wedge-type clamp mechanism, for oil cylinder is separated with the gyration of chuck, must lay bearing between voussoir and oil cylinder, when clamping force was very big, the cylinder thrust that needs was just very big, this bearing is running up down, under very big responsive to axial force, heating is serious, and the life-span is very short.The live load of rig is embodied as the rotary torque of rig and feeds power generally by the stratum decision, and moment of torsion is big more, and the power that feeds is big more, and the clamping force that then needs is just big more,
The utility model content
The utility model proposes a kind of simple in structure, respond well chuck at deficiency of the prior art.
The utility model is achieved by following technical proposals:
A kind of composite hydraulic chuck, it comprises interstage sleeve, fixed bearing, rotating shaft, expansion bearing, oil cylinder, pressure ring, drilling rod, oil cylinder one end is connected with fixed bearing, the oil cylinder other end is connected with expansion bearing, expansion bearing withstands sliding sleeve by bearing, and expansion bearing is enclosed within on the fixed bearing, it is characterized in that rotating shaft is socketed on the endoporus of spring, one end of spring withstands on the interstage sleeve inboard, and the other end of spring withstands sliding sleeve.
As preferably, the sliding sleeve in above-mentioned a kind of composite hydraulic chuck is connected with voussoir, and voussoir contacts with slips, and contact surface is an oblique mechanism.Such structure is the change of the direction of realizable force effectively, and guarantees the transmission of power.
As preferably, the slips described in above-mentioned a kind of composite hydraulic chuck has 6, is evenly distributed in the groove that is inserted in rotating shaft.Certainly, the design of the number of slips is in order to guarantee the transmission effect of power better, to reach the reasonability of entire equipment structure.
As preferably, the spring in above-mentioned a kind of composite hydraulic chuck is the spring string that the multi-disc spring is formed.So more can guarantee the prolongation in application life in use, though local impaired, and be unlikely to damage can not normally using of other parts.
Beneficial effect: the utility model can satisfy under the prerequisite of big clamping force, compact conformation, and in light weight, it is little to generate heat, the efficient height.Clamping force can be changed with the live load of rig, more meet the rig actual conditions.In the present technique, the source of clamping force is by spring and hydraulic pressure is compound provides, and promptly provides basic clamping force by spring, and hydraulic pressure provides additional clamping force, is to increase with moment of torsion or the increasing that feeds power and replenish clamping force.

The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is specified, but is not restriction of the present utility model:
Embodiment one
As structure as described in the accompanying drawing 1, the inner hole sleeve of spring 3 is in rotating shaft 4, and multi-disc spring 3 is formed the spring strings, and spring 3 one ends withstand on interstage sleeve 1, and the other end withstands on sliding sleeve 6, and when spring 3 was in compressive state, spring 3 tension force had just formed an axial power; Oil cylinder 7 one ends are connected with fixed bearing 2, the other end is connected with expansion bearing 5, expansion bearing 5 withstands on sliding sleeve 6 by bearing 8, expansion bearing 5 is enclosed within on the fixed bearing 2, can move axially, by the control of hydraulic system, pressure oil enters oil cylinder 7, oil cylinder 7 also produces an axial power, forms compound axial power with the stack of spring 3 tension force, promotes sliding sleeve 6.Sliding sleeve 6 is enclosed within the rotating shaft 4 and can moves axially, and sliding sleeve 6 is connected with voussoir 9, and voussoir 9 is an oblique mechanism with slips 10 contact surfaces, and when voussoir 9 moved axially, slips 10 moved radially; Slips 10 has 6, is evenly distributed in the groove that is inserted in rotating shaft 4, can move radially.Pressure ring 11 is connected with expansion bearing 5, withstands on voussoir 9 by bearing 8.
Operating principle: the main effect of oild chuck is clamping or unclamps drilling rod
Clamp drilling rod 12: spring 3 is in compressive state, under the effect of spring 3 tension force, promote sliding sleeve 6 and voussoir 9 and move right, under the oblique mechanism effect between voussoir 9 and the slips 10, slips 10 moves radially to the center, thereby clamp drilling rod 12. in this process, by the control of hydraulic system, oil cylinder 7 also produces an axial force, promotes sliding sleeve 6 by bearing 8, at this moment the axial force of oil cylinder 7 is identical with the spring tension direction, stacks up and has improved clamping force greatly.Unclamp drilling rod 12: under the control of hydraulic system, oil cylinder 7 produces an axial force, and this power is opposite with the spring tension direction, thereby overcome spring tension,, sliding sleeve 6 and voussoir 9 have been moved to the left by pressure ring 11 and bearing 8, make slips 10 deviate from the center and outwards move, thereby unclamp drilling rod.
