Abstract
The present invention relates to a kind of portable drill oild chuck, including the main shaft with central clamp through hole, the sidewall of described main shaft is provided with multiple slips installing hole around wherein heart septum, is radially movably installed with slips in described slips installing hole；The lateral surface of slips be inclined-plane and be provided with that coordinate with described inclined-plane, described slips can be squeezed the collar pushed away to the alignment of shafts, the bottom of described collar is installed on the outfan of slips oil cylinder, the upper end of collar is provided with spring base, the outer wall of the adjacent main shaft between described slips installing hole is provided with nitrogen spring, and the upper end of described nitrogen spring is connected with described spring base.The oild chuck of the present invention, uses slips oil cylinder to combine with nitrogen spring, it is achieved the reliable, stable of drilling rod is embraced folder by slips, compares traditional single hydraulic jack and drives slips to embrace folder mode, improves reliability and the stability embracing folder.
Description
Technical field
The present invention relates to geological prospecting apparatus field, particularly to the chuck on unit head on portable drill.
Background technology
In portable drill, the fluid chuck that unit head is installed, for embracing stick of tool bar, rotate with unit head, it is achieved bore
Take.Existing oild chuck, structure is complex, uses hydraulic jack to drive slips, carries out drilling rod embracing folder, and its armful of folder is reliable
Property, stability have much room for improvement.
Summary of the invention
The problems referred to above existed for oild chuck on existing rig, applicant studies and improves, it is provided that Yi Zhongbian
Take churn oild chuck, use hydraulic jack to drive slips and nitrogen spring to combine, improve chuck and drilling rod is held tightly
Stability and reliability.
In order to solve the problems referred to above, the present invention uses following scheme:
A kind of portable drill oild chuck, including the main shaft with central clamp through hole, the sidewall of described main shaft encloses
Wherein heart septum is provided with multiple slips installing hole, described slips installing hole is radially movably installed with slips；Outside slips
Side be inclined-plane and be provided with that coordinate with described inclined-plane, described slips can be squeezed the collar pushed 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.
The method have technical effect that:
The oild chuck of the present invention, uses slips oil cylinder to combine with nitrogen spring, it is achieved reliable, steady to drilling rod of slips
Fixed embracing is pressed from both sides, and compares traditional single hydraulic jack and drives slips to embrace folder mode, improves reliability and the stability embracing folder.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, main shaft；2, slips；3, collar；4, slips oil cylinder；5, spring base；6, nitrogen spring.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As it is shown in figure 1, the portable drill oild chuck of the present embodiment, including the main shaft 1 with central clamp through hole,
The sidewall of main shaft 1 is provided with multiple slips installing hole (such 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 that coordinate with inclined-plane, slips 2 can be squeezed to main shaft 1 center
The collar 3 pushed 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 move up and down by collar 3 relatively, and the outer wall of the adjacent main shaft 1 between 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 inclined-plane, outside of extruding slips 2, inwardly extrudes slips 2, thus drilling rod is held tightly by multiple slips 2, and nitrogen spring 6 is filled with simultaneously
Compressed nitrogen, keeps collar 3 to squeeze downwards thrust, thus ensures that drilling rod is stablized by slips 2, reliable embracing is pressed from both sides after cylinder body is drop-down；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
Holding tightly of bar.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not to this
Bright make any pro forma restriction, any art has usually intellectual, if without departing from the carried skill of the present invention
In the range of art feature, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and
Without departing from the technical characteristic content of the present invention, all still fall within the range of the technology of the present invention feature.
