Abstract
The invention relates to an elastic pull rod rack motor base comprising a fixed seat and a movable seat. The movable seat is arranged above the fixed seat. The fixed seat is connected with one side of the movable seat by a movable shaft, and the fixed seat is connected with the other side of the movable seat by a screw rod. The bottom of the screw rod is sleeved with a spring, and a nut is arranged below the spring. A motor is arranged above the movable seat, the lower part of the motor is provided with a gear, and the gear is meshed with a big incisor-shaped rack. The meshing degree of the motor gear and the big incisor-shaped rack can be adjusted dynamically, the motor is prevented from getting stuck, the output power of the motor is reduced, the current is smooth during output, rotation is smooth, power loss is reduced, and the service life of the motor is prolonged.
Description
Technical field
The present invention relates to a kind of Power-driven gate motor and the motor base fixed when using is installed, particularly relate to a kind of elastic draw bar rack rails motor base, be applicable to the installation and debugging work at transformer station's Large Electric gate.
Background technology
In prior art, the Large Electric gate rack rails of transformer station is engaged downwards, and output power of motor is comparatively large, and output current is unstable, and electric energy loss is large, and useful life is short, and it is stuck that motor easily occurs.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of elastic draw bar rack rails motor base, solve motor output current in prior art unstable, electric energy loss is large, and the stuck problem of motor easily occurs.
Technical scheme of the present invention is as follows:
Motor base comprises holder and sliding seat, sliding seat is arranged on the top of holder, and holder adopts movable axis to be connected with the side of sliding seat, and holder adopts lead screw to be connected with the opposite side of sliding seat, the bottom pocketed springs of lead screw, the below of spring is provided with nut; The top of sliding seat arranges motor, and the bottom of motor is provided with gear, and gear is engaged with gate toothed track.
Described holder and sliding seat are respectively equipped with fixing hole and adjusting hole, and lead screw stretches in fixing hole and adjusting hole, and the internal thread of fixing hole and adjusting hole and the external screw thread of lead screw match.
Described gate toothed track comprises rail body and rack rails, and rack rails arranges the top of body in-orbit, and rack rails is upwards engaged motor gear.
Described sliding seat comprises platform and supporting bracket, and side and the platform of supporting bracket are fixed, and the opposite side of supporting bracket connects movable axis.
Advantageous effect of the present invention is as follows:
1, top movable seat and bottom holder zoarium composition, wherein below top movable seat, lead screw is installed, lead screw is set with extension spring, lead screw is inserted in the fixing hole on holder and is adjusted lead screw position by extension spring attaching nut, reaches directly elasticity between adjustment gate rack rails and motor gear; Realize motor gear and gate rack rails degree of occlusion dynamic adjustments, avoid that motor occurs stuck.
2, after being engaged downwards by gate rack rails and changing upwards occlusion into, the defeated power reduction of motor, output is that electric current is steady, stability of rotation and reduce electric energy loss, extends motor useful life, for company has saved maintenance fund.
