Haulage winch with electromagnetic speed-regulating motor

Abstract

The invention discloses an haulage winch with an electromagnetic speed-regulating motor, which mainly comprises a bearing base (1), a coiling block (2), a safety brake (3) and the electromagnetic speed-regulating motor (4), wherein the right end of the coiling block (2) is connected with the safety brake (3), the left end of the coiling block (2) is connected with bearing base (1), and the right end of the safety brake (3) is connected with the electromagnetic speed-regulating motor (4). The haulage winch with the electromagnetic speed-regulating motor has the beneficial effects that: the electromagnetic speed-regulating motor has a simple structure, reliability for operating, practicability, and convenience for maintaining (no commutator and no slip ring), and is good in starting performance, low in control power, easy to automatically control and remotely control, wide in speed-regulating ratio (1:10), and relatively high in speed-regulating accuracy, so that the haulage winch with the electromagnetic speed-regulating motor is convenient for an operator to realize the medium / distant range control, the number of operators is reduced, and the labor productivity and the safety are improved.

Description

technical field [0001] The invention relates to a transport winch for loading and dispatching marshalled mine cars in the mine or on the ground, hauling the mine cars in the middle lane and other auxiliary handling work. Background technique [0002] The existing transport winches all adopt the structure of ordinary motor-reduction mechanism-drum, which has the disadvantages of complex structure, high manufacturing cost, low transmission efficiency, inconvenient operation and maintenance, and unfavorable for automatic control. Wherein the reduction mechanism accounts for more than 50% of the whole machine in terms of manufacturing cost and weight. [0003] The invention adopts the electromagnetic speed regulating motor to directly drive the reel, and drives the steel wire rope to pull the heavy object. The electromagnetic speed regulating motor is an AC stepless speed regulating motor with simple control, which is composed of an AC three-phase asynchronous motor, an eddy cu...
