The invention provides a method and a device for determining the deformation quantity of a cantilever crane, a cantilever crane system and engineering mechanical equipment, and relates to the technical field of engineering machinery. The method is applied to a processor in an arm support system and comprises the steps that parameter information, collected by a pressure sensor and a displacement sensor, of each section of mechanical arm in an arm support after deformation is obtained; according to the parameter information of each section of mechanical arm in the arm support after deformation, the bending moment and the inertia moment of the arm support end face corresponding to each section of mechanical arm in the arm support are determined; according to the disturbance curve equation corresponding to each section of mechanical arm in the arm support and the bending moment and the inertia moment of the arm support end face corresponding to each section of mechanical arm in the arm support, the deformation quantity of the tail end of the arm support is determined, and compared with an existing measuring method, the measuring method is simple in principle, convenient to operate and free of limitation of the measuring precision of a tilt angle sensor. The measuring precision is greatly improved, the cost is reduced, and the problems that an existing measuring method is easily limited by the measuring precision of a tilt angle sensor, and the tail end of the boom cannot be accurately positioned are solved.
Description
technical field [0001] The invention relates to the technical field of construction machinery, and in particular, to a method, a device, a boom system and construction machinery equipment for determining a deformation amount of a boom. Background technique [0002] As a rigid-flexible coupling body, the articulated manipulator is easily bent due to the force during the operation, resulting in elastic deformation, which affects the precise positioning of the end point of the manipulator. For example, taking the boom of a concrete pump truck as an example, the maximum deformation of the five-section manipulator can reach about 1m, and the mechanical deformation is difficult to directly and accurately measure and calculate. Therefore, in order to ensure operation safety and construction accuracy, it is necessary to measure the degree of bending deformation of the manipulator. [0003] At present, engineers and technicians mainly use multiple inclination sensors to measure the ...
