Abstract
The utility model discloses a pneumatic anchor bolt rock drill which is mainly characterized in that an extension shaft is connected on a power output shaft of a variable speed gearbox of the existing rotary percussion combine rock drill; a transmission gear is arranged on the extension shaft and meshed with a brazing tail sleeve gear; a rotary part and a rock drill shell are together fixed on a body base to form a whole rock drill; the supporting axis of an air leg is arranged on the gravity center line of the overall weight of the rock drill; and an air inlet pipe of an air motor is directly connected on a valve of a supporting vertical arm. The pneumatic anchor bolt rock drill has the advantages that the downward movement of the weight of the rotary part is realized, the front heaviness is avoided, the overall stability is improved, the direct percussion is avoided, the strong vibration in working is reduced, and the operation is convenient for the working personnel.
Description
Technical field
The utility model relates to hammer drill.
Background technology
Anchor rod hammer drill is the equipment that is used for beating square in the mine timbering.The technology relevant with the application is the disclosed rotary impact associating of Chinese patent publication number CN2864065 jumbolter, its primary structure is improved on the basis of original air drill, original air drill comprises by the hammer drill shell, impact part in the shell, the hammer drill body that air leg and control arm constitute, it mainly is to have increased rotating part that the disclosed rotary impact associating of publication number CN2864065 jumbolter improves structure, during improvement, the processing of hammer drill bit shank cover is cogged, hammer drill shell one side at bit shank cover position connects a change gear box, an air motor is installed in bottom at change gear box, air motor is by driving the rotation of bit shank cover after the change-speed gearing speed change, the function with rotary cutting is impacted in realization.Described in addition air motor is by an independent valve control air intake.
The deficiency of this improvement structure is: 1, because change gear box and air motor are arranged on former body head one side, away from hammer drill supporting leg axis of support, whole weight concentrates on the hammer drill head again, so when perforating, whole hammer drill is in top-heavy state and is difficult to control, produce a very big eccentric force when adding rotation again, the staff is more refractory; 2, owing to the air intake of air motor is controlled by separate valve, so operated very inconvenience.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, makes improvements, and provides a kind of impact rational in infrastructure rotary Pneumatic anchor rod hammer drill.
For reaching above-mentioned purpose, the technical solution of the utility model is: comprise hammer drill body that is made of the impact part in hammer drill shell, the shell, air leg, control arm and the rotating part of being made up of change gear box and wind motor, put at the bit shank of impact part and to be processed with gear, it is characterized in that: 1, connect an extension shaft on the power output shaft of change gear box, a travelling gear is installed on the extension shaft, and travelling gear meshes with the bit shank sleeve gear again; 2, rotating part and hammer drill shell are fixed on the body seat jointly, constitute a hammer drill integral body; 3, the axis of support of air leg is arranged on the center of gravity line of hammer drill overall weight; 4, the air inlet pipe of wind motor directly is connected on the valve of support trailing arm.
During work, by the diverse location of operated valve handle, realize impacting separately, rotation or impact add rotation separately, according to different rocky condition flexible modulation.
Good effect of the present utility model is: 1, rotating part overlaps transmission by extension shaft and bit shank, and the one, realized moving down of rotating part weight, avoided top-heavy phenomenon; The 2nd, after moving down, rotating part can be fixed on jointly on the body seat with the impact part, improved resistance to overturning, the 3rd, transmit a rotation power to bit shank by extension shaft and put, have the elastic transmission effect, avoided direct impact, the powerful vibrations when having reduced work; 2, the axis of support of air leg is arranged on the center of gravity line of hammer drill overall weight, makes the support force left and right sides balance during perforating, prevents eccentric force, and the staff controls easily; 4, the air inlet of air motor is operated by same valve handle with the air inlet of impacting part, and the staff is easy to operate.
