Abstract

The utility model discloses a lifting safety protection device for a radial drill, which is characterized in that a stand column is fixedly arranged on a base; a rocker is arranged on the stand column, so that the rocker has the degree of freedom of up and down movement on the stand column; a reduction box is fixedly arranged at the top end of the stand column, and meanwhile, an auxiliary motor is fixedly connected with the reduction box; a lifting screw rod is connected with the rocker in a screw thread fit way; a torsion limiting clutch is connected and arranged between the lifting screw rod and an output shaft of the reduction box; and the upper end and the lower end of the rocker, close to the stand column, are both fixedly provided with a stroke switch, and the upper surface of the stand column, positioned on the vertical stroke limiting part of the rocker, is provided with a fixed ring-shaped touch block. The lifting safety protection device for the radial drill effectively overcomes the defect that the motor is burned or related transmission parts are damaged during the lifting process of the rocker as a blocking phenomenon is caused between the screw rod and a screw nut, the rocker ascends or descends to the limiting position, and the control is out of order or has errors.

Description

Radial drilling machine elevating safety protective device

Technical field

The utility model belongs to the radial drilling machine safe practice, is specifically related to a kind of radial drilling machine elevating safety protective device.

Background technology

In existing 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 go out a this situation, might cause burn-down of electric motor or damage relevant driving parts.

Summary of the invention

The purpose of the utility model is: a kind of radial drilling machine elevating safety protective device is provided; It is existing to overcome existing radial drilling machine lowering or hoisting gear: in the rocking arm lifting process; Owing to occur blocked portion, rocking arm rising between leading screw and the feed screw nut or drop to extreme position; And under the situation that appearance control is malfunctioning or control is slipped up, the defective of the driving parts that burn-down of electric motor or damage are relevant easily.

The utility model realizes that the technical method that above-mentioned purpose adopted is: this utility model comprises base, column, rocking arm, elevating screw, limited torque clutch, reduction box, stand-by motor, annular collision block, travel switch.This utility model is said to be fixed on column above the base; rocking arm be movably arranged on column on; reduction box is fixed on the top of column, and simultaneously stand-by motor is connected fixingly with reduction box, the method for elevating screw through threaded engagement is connected with rocking arm;, be connected with the limited torque clutch in the output shaft of elevating screw and reduction box; Be fixed with a travel switch respectively at the two ends up and down of rocking arm one side, on the column at rocking arm up-downgoing way limit position, install and fix annular collision block.

Beneficial effect: the utility model 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 under the situation that appearance control is malfunctioning or control is slipped up, the defective of the driving parts that burn-down of electric motor or damage are relevant easily.
