The connector has large transmission torque, good shock absorbing performance and sealing performance, simple structure and long service life.
Description
Technical field
The utility model belongs to the mining machinery technical field, relates in particular to a kind of connector that is used on the rotary drill.
Background technology
The rotary drill that mining is used comprises boring rod set and Power Drive Unit two big major parts, and influence one of drilling rod performance quality principal element especially as the key mechanism-drill rod connector that connects this two large divisions, existing drill rod connector has two kinds: a kind of is the fixture block connector, that is: by coming transfer torque with two adapter sleeves of pegging graft mutually that boring rod set is connected with Power Drive Unit respectively, the end of these two adapter sleeves is respectively equipped with the staggered convex-concave platform that coincide and peg graft of phase mutual energy, and another kind is to be connected to come transfer torque with two junction plates that boring rod set is connected with Power Drive Unit by tens bolton respectively.The damping property, the sealing effectiveness that facts have proved these two kinds of connectors are all undesirable, and by bolted connector since operation process in vibration cause bolt looseness, often got rid of, have many potential safety hazards.
Summary of the invention
It is big that the purpose of this utility model provides a kind of transfer torque, and damping performance is good, and is simple in structure, a kind of connector that is used on the rotary drill of long service life.
The purpose of this utility model is to realize in the following manner:
A kind of connector that is used on the rotary drill of the present utility model, comprise active adapter sleeve that is connected with the Power Drive Unit of rotary drill and the driven adapter sleeve that is connected with the boring rod set of rotary drill, it is characterized in that described active adapter sleeve is by the power adapter sleeve that is connected with described Power Drive Unit, the external splines cover that is connected with the lower surface of annular connecting plate therewith of the annular connecting plate that is connected of power adapter sleeve is formed therewith, described driven adapter sleeve is made up of the inner spline housing that the drilling rod adapter sleeve that is connected with described boring rod set is connected with drilling rod adapter sleeve therewith, described external splines cover is connected with a joggle with described inner spline housing, described annular connecting plate is fastenedly connected by one group of bolt assembly and inner spline housing, damping glue ring I is located between the upper surface of the lower surface of described annular connecting plate and described inner spline housing, and a damping glue ring II is located in the endoporus of described external splines cover.
Big 20～30 ㎜ of height of described damping glue ring II aspect ratio external splines cover.
Described power adapter sleeve and annular connecting plate can be made into an integral body.
The utility model has the advantages that:
1) the utility model increases by two damping glue rings, and effectiveness in vibration suppression is obvious, favorable sealing property, and in the application life of each parts of prolongation rotary drill, the rate of starting of equipment obviously rises;
2) the utility model adopts spline to connect to come transfer torque, and the bearing load ability is big, and the concentricity height improves transmission efficiency;
3) the utility model is simple in structure, and easy installation and removal is practical.

Big 10～20 ㎜ of height of described damping glue ring II 6 aspect ratio external splines cover.After inside and outside spline housing engagement assembling, damping glue ring II 6 will be compressed distortion and fill up vestibule, make damping effect better.
Described power adapter sleeve 2 and annular connecting plate 3 and external splines cover 5 can be made into an integral body.
Described drilling rod adapter sleeve 8 and inner spline housing 9 also can be made into an integral body.
The utility model is simple in structure, the practical value height, and long service life is adapted at wideling popularize in the rotary drill industry.
Claims (3)
