Abstract
The invention relates to a linear electric percussion pickaxe, which comprises a power portion and a percussion portion, wherein the upper portion of the percussion portion is fixedly connected with the power portion, the lower portion of the percussion portion is provided with an outer cylinder barrel with an upward opening, an inner cylinder barrel is inserted in the outer cylinder barrel, and the lower end of the inner cylinder barrel is in attacking fit with the base end of the outer cylinder barrel. A percussion piston is assembled inside the inner cylinder barrel, and a piston connecting rod is assembled on the percussion piston. The power portion is in the structure of an electromagnetic linear motor, and the lower end of an armature mover of the linear motor is utilized as the power output of the power portion and is in driving connection with the upper end of the piston connecting rod. The direct linear driving can also enable the utilization efficiency to be greatly increased, and the energy consumption is relatively lower. The utilization is very simple because an air pump is not needed to be assembled. In the process of continuous working, the error rate is lower, which is favorable for the ordinary operation of construction. In addition, the noise is low in the working course, which is helpful for the protection of the periphery environment and the health of constructors.

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 present invention 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 workmen.
