Abstract
The utility model provides an antivrbration pad mechanism on transmission shaft assembly, the first bolster, rubber pad and the second bolster that set gradually including from the top down, wherein first bolster both sides are equipped with picks up the ears, the both ends difference block of second bolster is in the bottom of first bolster, every the difference upper end and the side edge that pick up the ears, the thickness that upper end one end is slope form and upper end is greater than side edge. The utility model discloses the during operation utilizes first bolster, rubber pad and second bolster to combine, and percussion drill or reduce reaction force in the time of can the cancel job has prolonged the life of drilling tool, improves work efficiency.
Description
Technical field
The utility model is related to the crash roll machine that a kind of oil mine is bored on field, more particularly to a kind of driving-shaft assembly
Structure.
Background technology
In oil mine drill-well operation, drive drilling tool to carry out operation using power transmission shaft, pass during operation at present
Often out drilling tool transfers to shaft bottom or percussion drill or anti-occurs during drilling tool is used when moving axis assembly and BHA are used
Active force, causes drilling tool damage, and operating efficiency is affected while increasing potential safety hazard, increases the maintenance cost of enterprise.
Utility model content
The utility model provides the crash roll mechanism on a kind of driving-shaft assembly, and reasonable in design, stabilized structure, its buffering is made
With, with percussion drill during cancel job or reaction force can be reduced, the service life of drilling tool is extended, improve operating efficiency.
The utility model is achieved through the following technical solutions：A kind of crash roll mechanism on driving-shaft assembly, including
The first bolster, rubber blanket and the second bolster for setting gradually from top to bottom；Wherein described first bolster both sides are provided with side
Ear, the two ends of second bolster are fastened on respectively the bottom of first bolster；The difference upper end picked up the ears described in each
Portion and side portion, described upper end one end is oblique and thickness of upper end is more than side portion.
It is as further improvement of the utility model：The thickness of the upper end of picking up the ears is with side portion thickness proportion
2:1。
It is as further improvement of the utility model：The upper and lower ends of the rubber blanket are embedded by shock structure respectively
It is fixed on the first bolster and the second bolster, the shock structure includes extension and bouncing ball, can so improve rubber
Pad and the first bolster and the adhesion and tensile force of the second bolster.
It is as further improvement of the utility model：The upper of the bouncing ball disperses respectively several pawl arms, increases
Structural strength.
Combined using the first bolster, rubber blanket and the second bolster during utility model works, energy can be with cancel job
When percussion drill or reduce reaction force, extend the service life of drilling tool, improve operating efficiency.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
First embodiment：
As shown in Figure 1, 2, 3：Crash roll mechanism on a kind of driving-shaft assembly of the present embodiment, including from top to bottom successively
The first bolster 1, the bolster 2 of rubber blanket 3 and second for arranging；The wherein described both sides of first bolster 1 are provided with picks up the ears 4, described
The two ends of the second bolster 2 are fastened on respectively the bottom of first bolster 1；Pick up the ears described in each 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 blanket and the second bolster, can with percussion drill during cancel job or
Person reduces reaction force, extends the service life of drilling tool, improves operating efficiency.
Second embodiment：
Such as Fig. 2,3,4：Crash roll mechanism on a kind of driving-shaft assembly, including the first buffering for setting gradually from top to bottom
Part 1, the bolster 2 of rubber blanket 3 and second；The wherein described both sides of first bolster 1 are provided with picks up the ears 4, the two of second bolster 2
End is fastened on respectively the bottom of first bolster 1；Pick up the ears described in each 4 difference upper end and side portion, the upper end
Portion one end is oblique and thickness of upper end is more than side portion.
The upper and lower ends of wherein described rubber blanket 3 are delayed respectively by embedded first bolster 1 and second that is fixed on of shock structure 5
In stamping 2, the shock structure 5 includes extension 6 and bouncing ball 7；The upper of the bouncing ball 7 disperses respectively several pawl arms 8.
The beneficial effect of the present embodiment is：Using extension and bouncing ball, rubber blanket and the first buffering can be so improved
The adhesion 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 operating efficiency.
