Abstract
The utility model provides a drilling machine power transmission device. Through holes (1) are distributed in end surface of the drilling machine power transmission device in the circumference direction, a bolt is arranged in each through hole (1), and the other end of the bolt is provided with a gasket and a nut. According to the drilling machine power transmission device, original screw holes are replaced by the through holes, screws are replaced by the bolts and the nuts, and the bolts, the nuts and the gaskets are matched to conduct fastening. The modified drilling machine power transmission device prolongs the service life, and reduces the amount of maintenance and the maintenance cost.
Description
Technical field
The utility model relates to a kind of mining hydraulic drilling rig, refers more particularly to the structure of rig power transmission.
Background technology
Present power transmission is to connect with screw, namely circumferentially has screw at the power transmission end face, then screw is screwed in.But, when screw damages, can cause whole power set can't continue operation, even cause power transmission to scrap, time-consuming when particularly keeping in repair this device, effort.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of rig power transmission is provided, substitutes original screw connecting mode, avoid causing device normally to move or to scrap because screw or screw damage.
Technical solutions of the utility model are: a kind of rig power transmission, its end face is along circumferentially being distributed with through hole.Be bolt in the through hole, the other end of bolt is pad and nut.After changing through hole into from screw, needn't worry that original screw internal thread damages, or screw breaks in screw.In case damage, the replacing of through hole and screw bolt and nut is also convenient.
The utility model has replaced original screw with through hole, changes screw into screw bolt and nut, and tie spacer carries out fastening simultaneously.Device after the improvement has improved its application life, has alleviated maintenance capacity and maintenance cost.
Description of drawings
Fig. 1 is power transmission schematic cross-section before improving;
Fig. 2 is for improving back power transmission schematic cross-section;
Fig. 3 is the right view of Fig. 2.
The specific embodiment
As shown in Figures 2 and 3, a kind of rig power transmission, its end face is bolt along circumferentially being distributed with through hole 1 in the through hole 1, the other end of bolt is pad and nut.Bolt passes the through hole 1 of power transmission end face, carries out fastening with the nut tie spacer.
The utility model is simple to operate, changes convenient, fast during bolt failure.
