Three-dimensional moment limiter for crane and crane including same

Abstract

Disclosed is a three-dimensional moment limiter of a crane, comprising a display module (1), a storage module (2), a calculation control module (3) and a detection module (4) that are connected to each other. The calculation control module invokes pre-stored current main components of a crane to perform three-dimensional modeling based on Direct3D and OpenGL technologies, and assembles, according to detected current setting parameters of the crane, a three-dimensional model identical to the crane of the actual scenario, then simulates, according to the product model, work condition, operating parameters and working environment of the crane, a three-dimensional scene of the working environment in real time. Also disclosed is a crane comprising the three-dimensional moment limiter. The three-dimensional moment limiter of the present invention not only has the function of a general moment limiter, but also has the function of displaying the working state of a crane in an all-round and three-dimensional way as well as in real time. Such a human-centered design enables an operator to observe the current working state of the crane more intuitively, thereby improving operating efficiency.

Description

technical field [0001] The invention relates to the technical field of crane safety, in particular to a three-dimensionally displayed moment limiter of a crane and a crane including the moment limiter. Background technique [0002] Cranes often work in complex and harsh environments. In order to prevent accidents such as tipping and arm folding caused by misoperation and overloading of the crawler crane during hoisting, the crane must be equipped with a moment limiter to ensure safe operation and as a safety protection. The torque limiter of the device must have high reliability, stability and detection accuracy. [0003] The torque limiter is an independent safety operating system completely controlled by a computer. It is generally composed of a display, a single-chip computer control box, an angle sensor, a length sensor, a pressure (pull) force sensor and an oil pressure sensor. The hoisted quality and the angle of the jib, and can display its rated load and actual load...

Problems solved by technology

But now almost all torque limiters are two-dimensional interfaces, users can only observe the current operating status of the crane through a picture, and cannot understand the overall working status of the crane
