Abstract
The utility model relates to a linear electric impact pickaxe, comprising a power part and an impact part. The upper part of the impact part is fixed with the power part and the lower part of the impact part is provided with an external cylinder barrel which has an upturned opening, in which an internal cylinder barrel is inserted and arranged. The lower end of the internal cylinder barrel cooperates with the bottom end of the external cylinder barrel via a stroke and the internal cylinder barrel is provided with an impact piston on which a piston connecting rod is arranged. The power part is a linear motor structure of electromagnetism and the lower end of a gag bit active cell of the linear motor has a transmission connection with the upper end of the piston connecting rod, serving as a power output of the power part. A direct linear drive improves the utilizing rate of the energy with low energy consumption. Because the utility model does not need to be equipped with a pump, the use is very convenient with a low failure rate and easy construction during a continuous work process. The small noise can also protect the surrounding environment and the health of the builders.

The utility model content
At the problems referred to above, task of the present utility model provides a kind of straight line electric impacting pickaxe, and the mode that drives with linear reciprocation directly drives impacting pickaxe work, simplifies the structure of impacting pickaxe, reduces the noise that produces in the course of work.
For finishing above-mentioned task, the technical solution of the utility model is: a kind of straight line electric impacting pickaxe, this impacting pickaxe comprises power section and impacts part, top and the power section of impacting part are fixed together, the bottom of impacting part is provided with opening outer cylinder up, be fitted with inner cylinder tube in the outer cylinder, the inner cylinder tube lower end impacts with the outer cylinder bottom and cooperates, be equipped with impact piston in the inner cylinder tube, be equipped with piston rod on the impact piston, described power section is the electromagnetic type structure of the linear motion actuator, and the lower end of the armature formula mover of linear electric motors is in transmission connection as the power output of power section and the upper end of above-mentioned piston rod.
Described electromagnetic type linear electric motors are the electromagnet type structure, coil installs around on the outer wall of pipe-shaped core, column armature is installed in the centre bore of pipe-shaped core, and the lower end of column armature and the upper end of piston rod are in transmission connection, the dead in line of column armature and piston rod.
The inner cylinder tube at impact piston rigging position place is provided with the air intake-exhaust structure.
Described air intake-exhaust structure is made of the groove of the above-below direction of twice one on the other that is provided with on the inner cylinder tube inwall, by the lower end of last groove and by under groove the upper end vertically have overlapping, impact piston be assemblied in by under the length section of groove on, by under vertical span of groove greater than vertical span of impact piston.
Outer cylinder is provided with lower house, and lower house is enclosed in inner cylinder tube, impact piston and piston rod in the seal cavity.
Impact cooperation position at inner cylinder tube and outer cylinder and be provided with cushion blocking.
Be provided with the axial adapter sleeve that is connected with broken pick of being used in the bottom of outer cylinder.
The utility model changes power section into the electromagnetic type structure of the linear motion actuator, the lower end of the armature formula mover of linear electric motors is in transmission connection as the power output of the power section upper end with above-mentioned piston rod, driving by corresponding oscillation generating circuit and amplification driving circuit, electric current in the coil is commutated by design cycle property ground, can realize the cyclically-varying of the electromagnetic force of coil, make armature do the reciprocating motion of rectilinear direction, directly drive the function that pick realizes that pick is hit again, thereby replace existing pneumatic actuation mode by the connecting rod driven plunger.Armature is done the reciprocating motion of rectilinear direction, directly drive the function that pick realizes that pick is hit again by the connecting rod driven plunger, structure is comparatively simple, not only low cost of manufacture but also the reliability and durability property of equipment is fully brought into play.Simultaneously, directly linear drives also makes the utilization ratio of energy improve greatly, and energy consumption is lower.Owing to do not need to be equipped with air pump, very convenient to use, in the process of continuous operation, fault rate is low, and what help to construct normally carries out.In addition, noise is low in the course of work, all can play a protective role to the healthy of surrounding environment and constructor.
