Problems solved by technology

During this process, in order to ensure that the front end of the tower arm always touches the ground, the operator needs to coordinate and control the hoisting action of the main arm and the tower arm to prevent the tower arm from being pulled up and cause the risk of forward tilt. The operation is complicated and the reliability is poor.

Abstract

The invention provides a crane, a tower arm control method and a tower arm control device, and relates to the technical field of engineering machinery. When the main arm stretches, the controller obtains the actual angle between the tower arm and the mast structure; adjusts the retracting speed of the winch according to the comparison between the actual angle and the preset safe angle range so that the actual angle is stable at the preset Safe angle range. In the tower arm control device, the acquisition module is used to obtain the actual angle between the tower arm and the mast structure; the control module is used to adjust the winding speed of the winch according to the comparison between the actual angle and the preset safe angle range. The crane, the control method of the tower arm and the control device of the tower arm can facilitate the coordinated control of the winch and the main arm. The risk of vehicle overturning due to the lifting of the tower arm from the ground is convenient for operation and good in reliability.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a crane, a tower arm control method and a tower arm control device. Background technique [0002] For a crane with a longer tower arm, due to the longer tower arm and greater mass, it is necessary to ensure that the front end of the tower arm touches the ground for a period of time during the initial boom process, so as to prevent the crane from tilting forward. During this process, in order to ensure that the front end of the tower arm always touches the ground, the operator needs to coordinate and control the hoisting action of the main arm and the tower arm to prevent the tower arm from being pulled up and cause the risk of forward tilting. The operation is complicated and the reliability is poor. Contents of the invention [0003] The purpose of the present invention includes providing a crane, a control method for a tower arm and a control device for a tower ...
