Summary of the invention
The purpose of this utility model is: for above-mentioned the deficiencies in the prior art, provide a kind of power transmission shaft flexible axle application life of can effectively prolonging, reduce the planet vibrating type electric tamping pick of frequency of maintenance and maintenance cost.
The technical solution adopted in the utility model is: a kind of planet vibrating type electric tamping pick, comprise motor, power transmission shaft, pick body and operator handle, and described motor is installed in the operator handle, and the transmission in the output of motor and connecting interface and the striker is coupling; Described power transmission shaft is made of the top connection, spring, flexible axle and the connector that connect successively, and connector is assemblied in the pick body by oscillating bearing, and is connected with vibrating shaft in the pick body, to the vibrating shaft transmitting torque; Described connector is comprised of cubic bulb, cubic hole connector and swivel nut; The upper end of described cubic bulb connects flexible axle, and the lower end is assemblied in the endoporus of cubic hole connector, leaves the gap between at the bottom of the lower end of cubic bulb and the hole of cubic hole connector; Described swivel nut is threaded in the top of cubic hole connector, and the bottom of cubic hole connector connects vibrating shaft.
The outer wall of described cubic bulb is installed on the top of swivel nut in the flange mode, form cannelure at the place, end, upper end of cubic hole connector.
Be provided with steel ball in the gap between described cubic bulb and the cubic hole connector.
Described motor is installed in the operator handle by the rubber shock-absorbing ball.
The connecting interface of described motor output end is connected with striker by the rubber shock-absorbing ball.
The lower end of described operator handle is connected with striker by damping spring.
The beneficial effects of the utility model are: above-mentioned tamping pickaxe is under the prerequisite that satisfies planetary friction vibration requirement, the lower contact of power transmission shaft is replaced with the connector of ad hoc structure, under the effect of connector, the flexible axle of power transmission shaft is only done axial moment of torsion transmission and absorbing, do not do high frequency deflection, effectively reduce the bending deformation quantity of flexible axle, steel wire in the flexible axle can not be in contact with one another, friction, thereby avoided flexible axle to be twisted off, improved greatly the working environment of flexible axle, prolonged the application life of flexible axle, frequency of maintenance and the maintenance cost of whole tamping tool are low, practical.
