Abstract

The embodiment of the invention discloses a crane, a crane trolley as well as a control method and a control device of the crane trolley and relates to the field of control of cranes. The control method comprises the following steps of: controlling the speed of the crane trolley according to a preset speed change curve to make sure that the crane trolley does reciprocating motion with respect to apreset point in a preset period, wherein the maximum distance from the crane trolley to a first preset point is a movement threshold value of the crane trolley in the preset period; and in any two adjacent preset periods, the movement threshold value of the crane trolley in the last preset period is larger than the movement threshold value of the crane trolley in the next preset period. The crane, the crane trolley as well as the control method and the control device of the crane trolley disclosed by the invention can make the crane trolley be parked at a specified preset point and can prevent shake.

Description

technical field [0001] The invention relates to the field of crane control, in particular to a crane, a crane trolley and a control method and device thereof. Background technique [0002] In the prior art, in a crane adopting a manual anti-sway strategy, it is necessary to output through a control handle to realize the anti-sway of the crane. However, when the operator does not know where to stop, the operator cannot know when to stop the output of the handle to stop the anti-swing control, so overshooting cannot be avoided. Contents of the invention [0003] The object of the present invention is to provide a crane, a crane trolley and a control method and device thereof, which can make the crane trolley stop at a designated preset point and be anti-sway. [0004] In order to achieve the above object, the technical solution adopted in the embodiment of the present invention is as follows: [0005] In a first aspect, an embodiment of the present invention provides a met...
