Abstract

The invention discloses a winch control method, a control device, a control system and engineering machinery. The winch control method comprises the following steps of: receiving a signal associated with the rotating speed of a winch (10); obtaining a parametric value from the signal, wherein the parametric value is associated with the rotating speed; comparing the parametric value with a set threshold value; and outputting a vibrating signal associated with the rotating speed of the winch (10) to a vibrator (60) under the condition that the parametric value is more than the set threshold value. With the adoption of the scheme, the problem of continuously electrifying and heating the vibrator (60) can be avoided.

Description

technical field [0001] The invention relates to the field of engineering machinery. Background technique [0002] At present, a vibrator is installed in the operating handle of the winch applied to various construction machinery (such as cranes). A proximity switch is arranged on the power supply circuit of the vibrator. Such as figure 1 As shown, the proximity switch is installed on the proximity switch mount 20 on the winch 10 . Such as figure 2 shown in figure 1 The toothed signal induction sheet is installed on the hoisting 10 shown. The tooth-shaped signal induction sheet is composed of a plurality of metal sheets 30 to form a gear-shaped circular body, which can rotate together with the winch 10 . When the winch 10 rotates, the metal sheet 30 on the tooth-shaped signal sensing piece also rotates. When one of the metal sheets 30 turns to the sensing position of the proximity switch, the proximity switch will be triggered to close the proximity switch. When the t...
