Abstract
The utility model discloses a gadder automatic drill-clamping mechanism which is a component of a gadder in particular to a pusher leg drill. The gadder automatic drill-clamping mechanism aims at solving the problems existing in the manual drill rods installation operation in the prior art and achieving automatic clamping and loosening. The gadder automatic drill-clamping mechanism comprises a handle body, a cylinder body, a machine head and auxiliary air legs. The front end of the handle body is connected with the cylinder body, a piston and a valve component are arranged in the cylinder body, the front end of the cylinder body is connected with the machine head, and air inlet hole channels are formed in the bottom of the cylinder body and the upper portion of the machine head. A small cylinder is arranged on the upper end of the machine head, and the piston, a spring, a clamp ring, a guide rod and a positioning pin are arranged in the small cylinder. A drill clamp is installed through the guide rod and the positioning pin, and the air inlet hole channels in the cylinder body and the machine head are communicated with the small cylinder. An operation handle and a spanner are communicated with compressed air, so that automatic clamping and loosening of the drill clamp can be achieved. The gadder automatic drill-clamping mechanism is a component of the gadder, and used for manufacturing complete gadders.
Description
Technical field
The utility model relates to hammer drill, particularly pusher leg drill, specifically hammer drill automatic clamping pricker mechanism.
Background technology
The pusher leg drill dress drill steel operation of using is at present completed by manual operation, and the problem of existence is: 1, complex operation, and easily crush operator's hand, the initiation security incident; 2, in rock drilling process, because of vibrations for a long time, easily make loosening even the coming off of drill steel and cause stopping work or security incident, affect the operating efficiency of hammer drill, limited the range of application of hammer drill.Understand according to investigations, there is no before this effective solution.
Summary of the invention
Problem for the existence of existing hammer drill dress drill steel operation, the utility model has been researched and developed a kind of automatic clamping pricker technology, and provide a kind of rational in infrastructure, reliable operation, easy to operate hammer drill automatic clamping pricker mechanism, to enhance productivity, associated safety hidden danger in the cancel job process guarantees the stable normal operation of hammer drill.
the technical solution of the utility model is as follows: hammer drill automatic clamping pricker mechanism comprises the handle body, cylinder body, head and auxiliary air leg, handle body front end connects cylinder body, piston is housed in cylinder body, valve tank valve cap assemblies is equipped with at the piston rear, the cylinder base back segment has the air inlet duct, leading portion has cylinder circular cone composite holes and cylinder duct, this cylinder is equipped with valve on the duct, the cylinder body front end connects head, fairlead is equipped with in the junction, the head front top is equipped with cylinder, the head internal upper part is shaped with the air inlet duct, this rear end, air inlet duct communicates by the cylinder duct of fairlead and cylinder base, the other end communicates with cylinder, piston and guide rod are housed in cylinder, guide rod connects the pricker card, fix with alignment pin.
The course of work of the present utility model: the handgrip on the handle body is placed in the running position, cocking to air leg retract fully (in accompanying drawing, air leg is not shown), compressed air enters the air inlet duct of cylinder base from the handle body, enter the air inlet duct of fairlead and head internal upper part through composite holes and cylinder duct, then enter cylinder, pushing piston and guide rod drive the pricker card and rotate, make the pricker card be in relaxation state, just can unload drilling tool.When the valve on cylinder base cylinder duct is in when upspringing state, piston is got back to initial position automatically under the effect of spring restoring force, drives the pricker card and rotates and be returned to card pricker position.Complete a circulation.
Compare with existing hammer drill, outstanding feature of the present utility model is: 1, connect reliably, can not get loose because of the vibrations in the course of work, thereby guaranteed that the rock drilling operation carries out smoothly, improved production efficiency; 2, owing to being by the cylinder automatic operation, thereby easy and simple to handle, can not crush again operator's hand, improved safety in utilization, stopped this type of security incident.
