Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the application of a crane in construction machinery as an example.

[0020] figure 1 is a flowchart of the main steps of Embodiment 1 of the anti-rollover control method according to the embodiment of the present invention, and, figure 1 It shows the main steps of the anti-overturning control method of the present invention when the crane is in the hoisting mode, as figure 1 As shown, the method mainly includes the following steps:

[0021] Step S101: Determine whether the moment limiter of the crane is in an invalid state, if so, execute step S103, otherwise the crane is in a normal working state under the hoisting working mode.

[0022] During the working process of the crane in i...

Abstract

The invention provides an anti-tipping control method, an anti-tipping control device and an anti-tipping control system and an engineering plant, which are used for solving the problem of frequent tipping accident of the engineering plant under the condition of uncompacted floor or over-loaded hoisted object in the prior art. The method comprises the following steps of: receiving a dip angle detection signal of the engineering plant; converting the dip angle detection signal into a deviation angle value; if the deviation angle value is greater than a preset deviation angle maximum threshold,outputting a corresponding action instruction for stopping increasing the deviation angle value; and if the deviation angle value is less than a preset deviation angle minimum threshold, outputting acorresponding action instruction for stopping reducing the deviation angle value. By adopting the technical scheme, the safety and the reliability of the engineering plant are favorably improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an anti-overturn control method, device and system, and construction machinery. Background technique [0002] With the continuous expansion of the construction site project scale, users have more and more requirements on the driving or hoisting performance, automation degree, work safety and reliability, and equipment fault diagnosis capabilities of construction machinery under various complex construction conditions. The higher it is, the more important it is to consider its safety and reliability. [0003] In the existing construction machinery control system, the anti-tipping function of the construction machinery is not considered, and it is very easy to tip over when the ground is not solid or the hanging objects are too heavy. [0004] In the existing technology, under certain working conditions, especially when the ground is not solid or the hanging objects are too h...
