Abstract
The present invention provides the crash roll mechanism on a kind of driving-shaft assembly, including the first bolster, rubber pad and the second bolster set gradually from top to bottom；Wherein described first bolster both sides are equipped with and pick up the ears, and the both ends of second bolster are fastened on the bottom of first bolster respectively；Each difference upper end picked up the ears and side portion, described upper end one end is oblique and the thickness of upper end is more than side portion.Combined during present invention work using the first bolster, rubber pad and the second bolster, with percussion drill during cancel job or can reduce reaction force, extend the service life of drilling tool, improve work efficiency.
Description
Technical field
The present invention relates to a kind of oil mine to bore the crash roll mechanism on field, more particularly to a kind of driving-shaft assembly.
Background technology
In oil mine drill-well operation, drilling tool is driven to carry out operation using transmission shaft, at present the transmission shaft during operation
Assembly and drill assembly using when often come out drilling tool and transfer to during shaft bottom or drilling tool use and percussion drill or reaction occur
Power, causes drilling tool damage, influences work efficiency while increasing security risk, increases the maintenance cost of enterprise.
The content of the invention
The present invention provides the crash roll mechanism on a kind of driving-shaft assembly, and design is reasonable, stabilized structure, its cushioning effect,
With percussion drill during cancel job or reaction force can be reduced, extend the service life of drilling tool, improve work efficiency.
The present invention is achieved by the following technical solutions：A kind of crash roll mechanism on driving-shaft assembly, including from upper
The first bolster, rubber pad and the second bolster set gradually under；Wherein described first bolster both sides are equipped with and pick up the ears, institute
The both ends for stating the second bolster are fastened on the bottom of first bolster respectively；Each difference upper end and side picked up the ears
Edge, described upper end one end is oblique and the thickness of upper end is more than side portion.
It is as a further improvement on the present invention：The thickness of the upper end of picking up the ears and side portion thickness proportion are 2:1.
It is as a further improvement on the present invention：The upper and lower ends of the rubber pad are embedded in by shock structure fix respectively
On the first bolster and the second bolster, the shock structure includes extension and bouncing ball, can so improve rubber pad with
The combination power and tensile force of first bolster and the second bolster.
It is as a further improvement on the present invention：The upper of the bouncing ball disperses several pawl arms respectively, increases structure
Intensity.
Combined during present invention work using the first bolster, rubber pad and the second bolster, energy can be with during cancel job
Reaction force is bored or reduced, the service life of drilling tool is extended, improves work efficiency.

Fig. 1 is the structure diagram of the first embodiment of the present invention；
Fig. 2 is the structure diagram of the first bolster
Fig. 3 is the structure diagram of the second bolster；
Fig. 4 is the structure diagram of second embodiment of the invention；
Wherein the first bolsters of 1-, the second bolsters of 2-, 3- rubber pads, 4- pick up the ears, 5- shock structures, 6- extensions, 7- bouncing balls,
8- pawl arms.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
First embodiment：
As shown in Figure 1, 2, 3：A kind of crash roll mechanism on the driving-shaft assembly of the present embodiment, including set gradually from top to bottom
The first bolster 1,3 and second bolster 2 of rubber pad；Wherein described first bolster, 1 both sides are equipped with and pick up the ears 4, described second
The both ends of bolster 2 are fastened on the bottom of first bolster 1 respectively；It is each described pick up the ears 4 difference upper end and side
Portion；The thickness of wherein described 4 upper ends of picking up the ears and side portion thickness proportion are 2:1.
The present embodiment is combined using the first bolster, rubber pad and the second bolster, can with percussion drill during cancel job or
Person reduces reaction force, extends the service life of drilling tool, improves work efficiency.
Second embodiment：
Such as Fig. 2,3,4：A kind of crash roll mechanism on driving-shaft assembly, including set gradually from top to bottom the first bolster 1,
3 and second bolster 2 of rubber pad；Wherein described first bolster, 1 both sides are equipped with and pick up the ears 4, the both ends point of second bolster 2
The bottom of first bolster 1 is not fastened on；It is each described pick up the ears 4 difference upper end and side portion, the upper end one
End is oblique and the thickness of upper end is more than side portion.
It is slow that the upper and lower ends of wherein described rubber pad 3 are fixed on the first bolster 1 and second by the insertion of shock structure 5 respectively
In stamping 2, the shock structure 5 includes extension 6 and bouncing ball 7；The upper of the bouncing ball 7 disperses several pawl arms 8 respectively.
The beneficial effect of the present embodiment is：Using extension and bouncing ball, rubber pad and the first buffering can be so improved
The combination power and tensile force of part and the second bolster；And pawl arm is set, increase structural strength；Can with percussion drill during cancel job or
Person reduces reaction force, extends the service life of drilling tool, improves work efficiency.
