Problems solved by technology

[0004] After careful study of the prior art, the inventor of the present application found that although the inclination angle information of the boarding system displayed by the computer in the control room can intuitively reflect the inclination degree of the crane vehicle system, this cannot accurately reflect the overall inclination of the crane system. the stability of the car

Embodiment Construction

[0015] The technical solution in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0016] First introduce some professional knowledge involved in the present invention.

[0017] Cranes, especially crawler cranes, mainly include three major systems: jib system, loading system and unloading system. The jib system may include components such as main boom, tower jib, superlift mast, etc. Of course, if the working conditions are different, the components included in the jib system may also be different. In addition, the components included in the boom system may also be referred to a...

Abstract

The invention provides a method for detecting stability of a crane; the crane comprises a cantilever crane system, a mounted system and a dismounted system; the method comprises that: gravity center information of the cantilever crane system, gravity center information of the mounted system and gravity center information of the dismounted system are obtained; initial gravity center information ofthe crane is obtained according to the gravity center information of the cantilever crane system, the gravity center information of the mounted system, the gravity center information of the dismounted system and the rotary angle of the mounted system, relative to the dismounted system; practical gravity center information of the crane is obtained according to the initial gravity center information of the crane and an inclined angle of ground level of the crane, relative to the horizontal level. As the gravity center information of the crane can accurately show the stability degree of the crane, the method and the device can accurately reflect the stability degree of the crane.

Description

technical field [0001] The invention relates to a crane, in particular to a technique for detecting the stability of the crane. Background technique [0002] At present, in order to ensure that the crane works in a stable state, the stability of the crane needs to be checked frequently. [0003] Please refer to Figure 5 , Figure 5 It is a schematic diagram of an existing method for detecting the stability of a crane. An existing method for detecting the stability of a crane is as follows: an inclination sensor is installed on the turntable of the crane, and the sensor can detect the inclination of the crane in the left-right direction (ie the X direction) and the front-back direction (ie the Y direction). After the sensor detects the current angle parameter, it outputs a current signal that can reflect the inclination angle in the above-mentioned left-right direction and front-back direction to the PLC controller. The PLC controller transmits the detection result to the d...
