Abstract
The invention relates to a hydraulic chuck of a drilling machine, and the hydraulic chuck is characterized by comprising a machine shell. A hollow main shaft is mounted on the machine shell through a bearing; the main shaft is connected with a hydraulic motor through a gear pair; a slip sleeve ring is slidingly sleeved at the front end of the hollow main shaft; an elastic component is abutted against between stages of the slip sleeve ring and the hollow main shaft; one end of a piston is connected with the slip sleeve ring through a thrust ball bearing and the other end of the piston is slidingly sleeved in a chuck upper shell which is fixedly arranged on the machine shell; the slip sleeve ring is internally provided with at least three equant slips and the slips are provided with wedge-shaped inclined planes; and the slips are slidingly sleeved in a T-shaped groove which is inclined on the slip sleeve ring. The hydraulic chuck of the drilling machine provided by the invention has the advantages of simple structure, low manufacturing cost and convenience for operation; and a structure which combines a hydraulic and butterfly-shaped spring, the hollow main shaft and the slips is utilized, so that the chucking power to a drill rod is improved and the overlong drill rod can be clamped once, therefore, the labor intensity of a worker is reduced, the work efficiency is improved and the work is safe and reliable.
Description
Technical field
The present invention relates to a kind of chucking device of engineering driller drilling rod, especially relate to a kind of oild chuck of clamping borer drill rod.
Background technology
Chuck is a vitals of engineering driller, when construction, is used for clamping connection drilling rod and dismounting drilling rod, and clamps drilling rod by chuck, to drilling rod transfer torque and axial force.Chuck of the prior art adopts the lever chuck of frame for movement usually, and is little to the chucking power of drilling rod by manually-operated, and operator's labour intensity is big, and operating efficiency is also lower.A kind of engineering driller that adopts automatic storage lever apparatus and automatic loading and unloading drilling rod is arranged in the prior art, but its equipment volume and weight are all very big, cause bigger inconvenience to construction, and equipment cost are higher.
Summary of the invention
The applicant has carried out research and has improved to above-mentioned problem, and a kind of simple in structure, rig oild chuck that cost is low, easy to operate is provided, and improves the chucking power to drilling rod, alleviates operator's labour intensity, increases work efficiency.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of rig oild chuck comprises casing, and hollow spindle is installed on the casing through bearing, and main shaft connects hydraulic motor through gear pair; The slips lasso slides over the front end of hollow spindle, and elastic component supports and is contained between the step of slips lasso and hollow spindle; One end of piston is connected with the slips lasso through thrust ball bearing, and the other end of piston slides in the chuck upper casing of fastening devices on casing; At least be provided with the slips that three five equilibriums are installed in the slips lasso, slips is provided with the wedge shape inclined-plane, in the T type groove of the inclination of slips carriage on the slips lasso.
Further:
Said elastic component is a disk spring.
Technique effect of the present invention is:
A kind of rig oild chuck disclosed by the invention, simple in structure, low cost of manufacture; Easy to operate, adopt hydraulic pressure, disk spring, hollow spindle and slips structure combining, improve chucking power to drilling rod; Can a clamping overlength drilling rod; Alleviate operator's labour intensity, increase work efficiency, safe and reliable.

Fig. 2 is the A-A place sectional view of Fig. 1.
Fig. 3 is the B-B place sectional view of Fig. 2.
The specific embodiment
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1,2, shown in 3, the present invention includes casing 1, hollow spindle 2 is installed on the casing 1 through bearing 3, and during use, drilling rod passes hollow spindle 2, and hollow spindle 2 connects hydraulic motor 6 through gear wheel 4 and pinion 5.Slips lasso 10 slides over the front end of hollow spindle 2, and disk spring 12 supports and is contained between the step of slips lasso 10 and hollow spindle 2, also available other elastic components of disk spring 12 here, and the pretightning force of disk spring is better than common spring.One end of piston 8 is connected with slips lasso 10 through thrust ball bearing 9; The other end of piston 8 slides in the chuck upper casing 7; Chuck upper casing 7 passes through screw fixing device on casing 1; In piston 8 place's devices oil connection 13 is arranged at chuck upper casing 7, can inject hydraulic oil, be moved to the left thereby driven plunger 8 overcomes the elastic force of disk spring 12 through the gap 14 of oil connection 13 between piston 8 and chuck upper casing 7.Be provided with the slips 11 that three five equilibriums are installed in the slips lasso 10; Slips 11 is provided with the wedge shape inclined-plane; In the T type groove of slips 11 carriages on slips lasso 10, the axis of T type groove and slips lasso 10 is obliquely installed, and the wedge shape inclined-plane on the slips 11 cooperates with the T type groove of inclination; Can effectively axial force be converted into radial load, and self-lock ability is preferably arranged.
When reality is used, in the gap 14 of piston 8 and chuck upper casing 7, inject hydraulic oil through oil connection 13, because chuck upper casing 7 is connected on the casing 1 through bolt; Be Immobile; The elastic force that hydraulic oil makes piston 8 overcome disk spring 12 is moved to the left, and drives slips lasso 10 motion toward the left side through thrust ball bearing 9 simultaneously, because T type groove is obliquely installed the wedge shape inclined-plane in slips lasso 10 and on the slips 11; Slips 11 unclamps; It is middle to insert hollow spindle 2 to drilling rod like this, releases hydraulic oil through oil connection 13 then, and disk spring 12 resets and compresses slips 11 through slips lasso 10; Wedge shape inclined-plane on the slips 11 is converted into radial load with axial force, when making three slips 11 compresses drilling rod.Fluid motor-driven power drives drilling rod through slips 11 and does rotating through gear-driving speed-variable, and the present invention adopts the slips structure to help the drilling rod of a clamping overlength.
