The utility model aims at providing a clamp force is big, and the slips opening is abundant, inclined plane reinforcement formula normal close holder that whole size is little. The utility model discloses a holder front -end of spindle is installed on the cylinder body, the tail end at the holder main shaft is installed to the pressure disk, install the slip spider between the cylinder body in the holder main shaft outside and pressure disk, there is the ejector pad on the slip spider, rectangle mould spring has been placed between ejector pad and pressure disk, there is the piston outside the holder main shaft in the cylinder body, piston tail end top is on the ejector pad, there is card half through position sleeve fixed mounting on the holder main shaft, card half corresponds the spacing groove on the piston, install on the holder main shaft and decide the slips, it moves the slips to correspond on decide the slips, move slips and ejector pad fixed connection. The utility model discloses the rectangle mould spring small, that rigidity is big, longe -lived. The whole size of hydraulic pressure holder is little, easy operation, safe and reliable.
Description
Technical field
This utility model belongs to geological prospecting apparatus field.
Background technology
Clamper is a part for all-hydraulic power head churn, its objective is to clamp drilling tool in hole, prevents drilling tool sliding, clamper and unit head cooperating from can complete the action of dismounting drilling rod.Existing clamper is divided into several classes such as normally closed type clamper, clamper open in usual, combined type clamper.Normally closed type holder structure is compact, reliable operation, chucking power depend on that initial tension of spring is not affected by oil pressure, can clamp drilling tool quickly, reliably when unexpected power-off, prevents from running brill accident.Fluid pressure type clamper coordinates the combined operation being easily achieved complete machine, safe ready with hydraulic system, and chucking power is big.Large aperture deep prospecting is current development trend, it is therefore desirable to clamper has big clamping force.Require reliable clamping during clamper work, during separation, require that opening is abundant.How to solve big clamping force lower gripper size and excessive long will not become main task.
Summary of the invention
It is big that the purpose of this utility model is to provide a kind of clamping force, and slips opening is abundant, the normally closed clamper of inclined plane force increasing formula that overall dimensions is little.
nullClamper front-end of spindle of the present utility model is arranged on cylinder body，Platen is arranged on the tail end of clamper main shaft，Between cylinder body and platen outside clamper main shaft, slip spider is installed，Slip spider has pushing block，Rectangular mould spring it is placed with between pushing block and platen，Piston is had outside clamper main shaft in cylinder body，Piston tail end withstands on pushing block，Clamper main shaft is installed with card half by positioning sleeve，Stopper slot on the corresponding piston of card half，Clamper main shaft is provided with and determines slips，Slips is moved determining correspondence above slips，Dynamic slips is fixing with pushing block to be connected，Determine slips chuck determining to have on slips and determine slips draw-in groove，Determine slips draw-in groove to be followed by determining slips rectangular card，It is above that to determine slips domatic，Corresponding on dynamic slips determine slips chuck and determine slips draw-in groove and have slips chuck and dynamic slips draw-in groove，For dynamic slips rectangular card before dynamic slips draw-in groove，Domatic for dynamic slips below；It is coaxially installed with slips spring determining slips inner ring, and is installed with alloy block determining slips inner surface.
It is little by the i.e. available bigger clamping force of little initial tension of spring that feature of the present utility model is mainly slip spider inclination angle of inclined plane, get on the bus on the inclined-plane of slip spider and slips the groove of certain depth simultaneously, contact at slips ramp projections at slip spider ramp projections during clamping drilling rod, when unclamping drilling rod, slips is fitted completely with slip spider two inclined-plane, the axial displacement that slip spider is less i.e. can get bigger the moving radially of slips, makes well separated the preventing of slips and drilling rod wear and tear mutually.Employing volume is little simultaneously, rigidity big, the rectangular mould spring of life-span length.Hydraulic gripper overall dimensions is little, simple to operate, safe and reliable.

Detailed description of the invention
nullClamper main shaft 1 front end of the present utility model is arranged on cylinder body 2，Platen 10 is arranged on the tail end of clamper main shaft 1，Between cylinder body 2 and platen 10 outside clamper main shaft 1, slip spider 8 is installed，Slip spider 8 has pushing block 15，Rectangular mould spring 9 it is placed with between pushing block 15 and platen 10，Piston 3 is had outside clamper main shaft 1 in cylinder body 2，Piston 3 tail end withstands on pushing block 13，Clamper main shaft 1 is installed with card half 6 by positioning sleeve 7，Stopper slot on the corresponding piston 3 of card half 6，Clamper main shaft 1 is provided with and determines slips 4，Slips 12 is moved determining correspondence above slips 4，Dynamic slips 12 is fixing with pushing block 13 to be connected，Determine slips chuck 44 determining to have on slips 4 and determine slips draw-in groove 42，Determine slips draw-in groove 42 to be followed by determining slips rectangular card 43，It is above to determine slips domatic 41，Corresponding on dynamic slips 12 determine slips chuck 44 and determine slips draw-in groove 42 and have slips chuck 124 and dynamic slips draw-in groove 122，Dynamic slips draw-in groove 122 is above for dynamic slips rectangular card 121，Below for dynamic slips domatic 123；It is coaxially installed with slips spring 5 determining slips 4 inner ring, and is installed with alloy block 11 determining slips 4 inner surface.Determining the chuck between slips and dynamic slips and draw-in groove is worked in coordination, domatic for convenient turnover, rectangular card is used for limiting excessive movements.
Clamper main shaft of the present utility model is fixed on cylinder body, and main shaft, cylinder body, piston constitute a propelling movement oil cylinder, will promote slip spider compression rectangular mould spring at hydraulic oil effect lower piston.Slips moves laterally along main shaft groove under the effect of slips spring simultaneously, and when slips completely attaches to slip spider jog, slips opening reaches maximum, is kept completely separate with drilling rod.After cancelling hydraulic oil, rectangular mould spring promotes slip spider to reset, and slip spider promotes slips clamping drilling rod.
