Abstract

The invention relates to a stroke control device of a steel wire rope winch, which comprises a control box and a gear stroke controller, a miniature gear shaft and a guild sleeve shaft, wherein the gear stroke controller, the miniature gear shaft and the sleeve shaft are arranged in the control box, the control box is fixed on a reduction box shell in a roller, the gear stroke controller is arranged in the control box, and the guild sleeve shaft is arranged on the control box by a bearing; the gear end of the miniature gear shaft and the gear set of the gear stroke controller are meshed mutually, and the other end of the miniature gear shaft is inserted in the inner end of the guild sleeve shaft and is located by using a pin; and the external end of the guild sleeve shaft is of a square toe which is inserted in a square hole sleeve at the tail part of the reduction gear shaft in the roller. The invention has compact structure, adjustable stroke, accurate limit, stable transmission, convenient operation and maintenance, complete protection function and high automatism.

Description

technical field [0001] The invention belongs to the technical field of centralized control or automatic control, and relates to an actuator of a reciprocating electric drive device, in particular to a stroke control device of a wire rope winch. Background technique [0002] In the field of hoisting machinery technology, the wire rope hoist is a widely used equipment. The wire rope hoist completes the traction work by winding the wire rope on the drum, which can lift the load vertically, horizontally or obliquely. The stroke of the wire rope hoist needs to be controlled to ensure safety. In the prior art, the stroke control of the wire rope hoist is mainly controlled by a manual switch, that is, a limit switch (adjusting the stop block of the limit lever) is set on the roller, and a limit switch is set on the wire rope and the running distance. However, this stroke control mechanism has defects such as small application range, low limit accuracy, exposed stroke switch, bulk...
