Abstract
The utility model relates to a mining drill power head impact damping rotary mechanism, which is mainly used in the drilling holes in the coal mine comprising a damping seat (1), a nut (2), a stud (3), a disc spring (4) and a connector (5). Said connector (5) is fixed and connected with the end of a mine used drilling rig power head mainshaft (6), the back end of the damping seat (1) is axially inserted into the connector (5) and the center of the power head mainshaft (6), the intermediate shrould (11) of the damping seat (1) connects with the connector (5) using the stud (3) and the nut (2), and the disc spring (4) coats on the stud (3) between the back end of the intermediate shroud (11) of the damping seat (1) and the front end of the connector (5). The utility model can eliminate the impact for the power head mainshaft brought by the impact driling.
Description
Technical field:
The utility model relates to a kind of mining-drilling machine, is specifically related to a kind of mine driller power-head buffering, rotating mechanism.Be mainly used in the boring of coal mine roadway.Belong to mining boring field of mechanical technique.
Background technology:
Before the utility model was made, traditional mine driller power-head was single rotary drilling structure.It only is applicable under the working condition of soft rock and creeps into.As run into hard rock and then can't normally work, carry out percussive drilling even mix impactor, the impact that in the time of also can't eliminating percussive drilling because of its reasons in structure dynamic head main spindle is brought causes shorten greatly the application life of mining-drilling machine borehole drill construction.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of mine driller power-head buffering, rotating mechanism of the impact that dynamic head main spindle is brought can eliminate percussive drilling the time is provided.
The purpose of this utility model is achieved in that a kind of mine driller power-head buffering, rotating mechanism, it is characterized in that it comprises: buffing pad, nut, double-screw bolt, disk spring and connector, described connector is fixedlyed connected with the mine driller power-head main-axis end, the buffing pad rear end axially is inserted in connector and dynamic head main spindle center, convex shoulder links to each other with the connector outer rim with nut with double-screw bolt in the middle of the buffing pad, is nested with disk spring on the double-screw bolt in the middle of the buffing pad between convex shoulder rear end face and the connector front end face.
When rotary drilling by dynamic head main spindle by being slidingly connected, transfer torque is given buffing pad, drives drilling rod rotary work on it by buffing pad.When percussive drilling, absorb the impact that buffing pad transmits, borehole drill construction its life-span when percussive drilling is prolonged by the disk spring on the double-screw bolt.
Description of drawings:
Fig. 1 is the utility model mine driller power-head buffering, rotating mechanism structural representation.
The specific embodiment:
Referring to Fig. 1, the utility model mine driller power-head buffering, rotating mechanism mainly are made up of buffing pad 1, nut 2, double-screw bolt 3, disk spring 4 and connector 5.
Described connector 5 is fixedlyed connected with mine driller power-head main shaft 6 axle heads, buffing pad 1 rear end axially is inserted in connector 5 and dynamic head main spindle 6 centers, convex shoulder 11 usefulness double-screw bolts 3 link to each other with connector 5 outer rims with nut 2 in the middle of the buffing pad 1, are nested with disk spring 4 on the double-screw bolt 3 in the middle of the buffing pad 1 between convex shoulder 11 rear end faces and connector 5 front end faces.
Claims (1)
