Abstract
The invention discloses a novel double-rocker drilling machine lifting protection mechanism. In the mechanism, a vertical post is fixedly arranged on the upper side of a base; a rocker is arranged on the upper side of the vertical post; a speed reduction box is fixedly arranged at the top end of the vertical post; an auxiliary motor is fixedly connected with the speed reduction box; a lifting screw is connected with the rocker; and a torsion limiting clutch is connected and arranged between the lifting screw and an output shaft of the speed reduction box.
Description
Technical field
The present invention relates to a kind of pair of radial drilling machine up-down protection mechanism, particularly a kind of new type double radial drilling machine up-down protection mechanism belongs to the radial drilling machine technical field of structures.
Background technology
In existing pair of radial drilling machine, realize that the mechanism that rocking arm goes up and down directly drives the elevating screw realization by motor through reduction box, still; Owing in lifting process, blocked portion, rocking arm rising between leading screw and feed screw nut, occur or drop to extreme position, and occur controlling under the situation of malfunctioning or control error; At this moment; Motor will work on, in case this situation occurs, might cause burn-down of electric motor or damage relevant driving parts.
Summary of the invention
The objective of the invention is to: a kind of new type double radial drilling machine up-down protection mechanism is provided; It is existing to overcome existing radial drilling machine lowering or hoisting gear: occur controlling under the situation of malfunctioning or control error, cause the defective of burn-down of electric motor or the relevant driving parts of damage easily.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of new type double radial drilling machine up-down protection mechanism; It is to be fixed on above the base by column; With rocking arm be installed in column above, reduction box is fixed on the top of column, stand-by motor is connected fixing with reduction box; Elevating screw is connected with rocking arm, the limited torque clutch is mounted between the output shaft of elevating screw and reduction box.
Beneficial effect: a kind of new type double radial drilling machine up-down protection mechanism of the present invention; Can overcome in the rocking arm lifting process effectively; Owing to occur blocked portion, rocking arm rising between leading screw and the feed screw nut or drop to extreme position; And occur controlling under the situation of malfunctioning or control error, cause the defective of burn-down of electric motor or the relevant driving parts of damage easily.
