An automatic clutch device on the sub-shaft of shunting winch

Abstract

The invention relates to a novel automatic clutch device on a countershaft of a dispatching winch, wherein the novel automatic clutch device is simple in structure, safe and reliable and can effectively prevent a sliding block of the automatic clutch device on the countershaft of the dispatching winch from being clamped during use. The automatic clutch device comprises the countershaft, a copper sleeve, a gear device, a partition sleeve, a bearing, an end cover, a bearing seat, a sliding block device and a sliding key. The gear device comprises a gear, a pulley shaft and guide pulleys, wherein a spiral tooth M is arranged on one side of the gear close to the sliding block device, pulley grooves are arranged at two ends of the spiral tooth M, and the pulley grooves are provided with the guide pulleys. The sliding block device comprises a sliding block, a pulley shaft and guide pulleys, wherein a spiral tooth N is arranged on the sliding block at the position corresponding to the spiral tooth M of the gear, pulley grooves are arranged at two ends of the spiral tooth N, and the guide pulleys are arranged in the pulley grooves.

Description

Technical field: [0001] The invention relates to a clutch device, in particular to an automatic clutch device used on the secondary shaft of a shunting winch. Background technique: [0002] The shunting winch is suitable for dispatching trains when loading and unloading goods in railway train transportation places such as coal mines, coal preparation plants, power plants, cement plants, etc., and can also be used for hauling heavy objects. The automatic clutch device on the secondary shaft of the shunting winch is a device used to realize the clutch under the forward and reverse conditions of the dispatching winch, through which the purpose of freely retracting and unwinding the steel wire rope on the dispatching winch drum can be achieved. The patent application No. 201210529075 proposes a shunting winch, in which the automatic clutch device on the auxiliary shaft includes a spiral groove, a slider, a slip ring, helical teeth A, B and another friction device. When the auxil...

Problems solved by technology

However, since the position of gear A cannot be determined during countershaft reverse rotation, it is very easy to cause the peak phenomenon of helical teeth A and helical teeth B in the process of countershaft forward rotation and about to engage, so that the slip ring is stuck and gear A cannot be pushed normally. to turn

[0003] The invention relates to an automatic clutch device on the auxiliary shaft of a shunting winch, which has a simple structure, is safe and reliable, can effectively realize the automatic clutch of the slider and the gear, and can also effectively solve the problem of the automatic clutch device on the auxiliary shaft of the shunting winch. Technical problems such as top stuck during the process
