Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] The operation state detection and control method of the tower belt machine comprises the following steps:
[0024] 1. Establish a model for the mechanical system of the tower belt machine. According to the actual size of the tower belt machine, establish the mechanical model of the tower belt machine through CAD software. The present embodiment preferably Solidworks software.
[0025] 2. Carry out dynamic and static analysis on the mechanical model according to the theoretical working conditions.
[0026] First, the mechanical model of the tower belt machine is imported from the CAD software into the finite element analysis (CAE) software, and the element type, material properties, and grid division are defined in the finite element analysis software to obtain the finite element model of the mechanical model.
[0027] Then ad...

The invention discloses a method for detecting and controlling the operation state of a tower belt crane, which comprises the following steps: (1) establishing a mechanical model of a tower belt crane; (2) performing dynamic and static analysis on the mechanical model according to the theoretic working conditions to obtain the parameters of theoretic operation state of the tower belt crane; (3) performing dynamic and static analysis on the mechanical model according to the current practical working conditions to obtain the parameters of current practical operation state; and (4) comparing theparameters of the current practical operation state and the parameters of the theoretic operation state, judging the operation state of the tower belt crane, and performing specific control operationaccording to the operation state. The method disclosed by the invention not only can detecting the system parameter state of the tower belt crane and the change of the system parameter state during construction to guarantee construction safety and pre-estimate the potential danger, but also can avoid practical operation of the tower belt crane, reduce the practical operation cost and improve the utilization rate of the tower belt crane.
Description
technical field [0001] The invention relates to the field of state detection and control of hydraulic engineering construction equipment, in particular to a method for detecting and controlling the operating state of a tower belt conveyor, which is used to provide design and calibration of safe and stable operating parameters of a tower belt conveyor for concrete conveying equipment during the construction of a high concrete dam core, fault diagnosis and analysis data. Background technique [0002] The pouring of a large-scale water conservancy project dam is a systematic project with a very large total pouring amount and pouring intensity. Such a huge total amount of concrete pouring and pouring intensity must seek a rapid construction plan for concrete; Work will play a decisive role in the overall program. There are many links involved in large-scale construction machinery and the construction process, and the relationship is complex and dynamic. Therefore, how to ensur...
