Abstract

The utility model relates to hoisting equipment technical field, and a kind of electric hoist rail switching device, including fixed track and self-propelled electric hoist. Through fixed frame, fixed seat and rail switching mechanism cooperation, achieve the convenient conversion of electric hoist in multiple tracks. Rail switching mechanism is composed of rotating disc, motor and rotating track, motor is rotated by gear transmission to make rotating disc, rotating track rotates and is accurately connected with each fixed track. At the same time, the end of rotating track and the gap end of fixed track are designed by special structure, reduce the butt joint spacing, guarantee the smoothness of electric hoist across track. In addition, limit seat, contact switch and lever cooperate, accurately control rotation angle, prevent parts from being in contact and protect contact switch. The utility model is exquisite in structure, easy to operate, can significantly improve electric hoist use efficiency and working range, enhance operation safety and accuracy, prolong service life, meet the complex needs of industrial production.
