Abstract
The utility model relates to a hydraulic chuck for portable type drilling machine, including the main shaft that has central centre gripping through -hole, the lateral wall of main shaft is provided with a plurality of slips mounting holes around heart septum wherein, radial movable mounting has the slips in the slips mounting hole, the lateral surface of slips for the inclined plane and install and cant tie, can with the slips is to the crowded rand that pushes away of the alignment of shafts, install on the output of slips hydro -cylinder the bottom of rand, and the spring holder is installed to the upper end of rand, and is adjacent nitrogen spring is installed to the outer wall of the main shaft between the slips mounting hole, nitrogen spring's upper end with the spring holder links firmly. The utility model discloses a hydraulic chuck adopts slips hydro -cylinder and nitrogen spring to combine together, realizes that the slips presss from both sides reliable, stable the embracing of drilling rod, compares traditional single hydraulic cylinder drive slips and embraces the mode of clamp, has improved the reliability and the stability of armful clamp.
Description
Technical field
This utility model is related to geological prospecting apparatus field, particularly to the chuck on unit head on portable drill.
Background technology
In portable drill, the fluid chuck of installation on unit head, for embracing a stick of tool bar, rotate with unit head, realize boring
Take.Existing oild chuck, structure is complex, drives slips using hydraulic jack, drilling rod is carried out embrace folder, and its armful of folder is reliable
Property, stability have much room for improvement.
Utility model content
The problems referred to above existing for oild chuck on existing rig, applicant is studied and is improved, and provides one kind just
Take churn oild chuck, drive slips and nitrogen spring to combine using hydraulic jack, improve the holding to drilling rod for the chuck
Stability and reliability.
In order to solve the above problems, this utility model adopts following scheme：
A kind of portable drill oild chuck, including the main shaft with central clamp through hole, the side wall of described main shaft encloses
Wherein heart septum is provided with multiple slips installing holes, in described slips installing hole, is radially movably installed with slips；Outside slips
Side be inclined-plane and be provided with described inclined-plane cooperation, described slips can be squeezed the collar pushing away, described collar to the alignment of shafts
Bottom be installed on the outfan of slips oil cylinder, the upper end of collar is provided with spring base, adjacent described slips installing hole it
Between the outer wall of main shaft nitrogen spring is installed, the upper end of described nitrogen spring is connected with described spring base.
Of the present utility model have technical effect that：
Oild chuck of the present utility model, is combined with nitrogen spring using slips oil cylinder, realize slips to drilling rod can
Lean on, stable embracing is pressed from both sides, compare traditional single hydraulic jack and drive slips to embrace folder mode, improve the reliability embracing folder and a stability.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure：1st, main shaft；2nd, slips；3rd, collar；4th, slips oil cylinder；5th, spring base；6th, nitrogen spring.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.
As shown in figure 1, the portable drill oild chuck of the present embodiment, including the main shaft 1 with central clamp through hole,
The side wall of main shaft 1 is provided with multiple slips installing holes (as 7,5 etc.) around wherein heart septum, radially lives in slips installing hole
Move and slips 2 is installed；The lateral surface of slips 2 be inclined-plane and be provided with inclined-plane cooperation, slips 2 can be squeezed to main shaft 1 center
The collar 3 pushing away, the bottom of collar 3 is installed on the outfan of slips oil cylinder 4, and the upper end of collar 3 is provided with spring base 5, spring
Seat 5 can collar 3 relatively move up and down, and the outer wall of the main shaft 1 between adjacent slips installing hole is provided with nitrogen spring 6, nitrogen
The upper end of spring 6 is connected with spring base 5.
Drilling rod is placed in the central clamp through hole of main shaft 1, and slips oil cylinder 4 drives collar 3 to decline, the medial slope of collar 3
The outside inclined-plane of extruding slips 2, slips 2 is inwardly extruded, thus drilling rod is held tightly by multiple slips 2, nitrogen spring 6 is filled with simultaneously
Compressed nitrogen, keeps collar 3 to squeeze downwards thrust after cylinder body is drop-down, thus ensureing that slips 2 embraces folder to the stable, reliable of drilling rod；When
When needing to pull down drilling rod, the cylinder body of nitrogen spring 6 moves, slips oil cylinder 4 upwardly collar 3, thus contact slips 2 to brill
The holding of bar.
Embodiment provided above is better embodiment of the present utility model, is only used for convenient explanation this utility model, and
Non- this utility model is made with any pro forma restriction, any those of ordinary skill in the art, if without departing from
In the range of the carried technical characteristic of this utility model, using locally changing done by this utility model disclosed technology content or repair
The Equivalent embodiments of decorations, and without departing from technical characteristic content of the present utility model, all still fall within this utility model technical characteristic
In the range of.
