Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] figure 1 It is a structural schematic diagram of the system for determining the rope winding state of the reel provided by the present invention. Such as figure 1 As shown, the present invention provides a control system for a crane comprising a double hoisting mechanism, the double hoisting mechanism comprising a first hoisting mechanism and a second hoisting mechanism, the first hoisting mechanism and the second hoisting mechanism Each includes a reel, a rope wound on the reel, and a motor that drives the reel to rotate. The first lifting mechanism and the second lifting mechanism are used to drive the lifting and lowering of the hook beam. The system...

Abstract

The invention discloses a crane control method, a system and a crane. The method comprises: acquiring an image capable of showing rope winding state on a coiling block; performing decoding and binarization processing on the image to generate a data matrix; determining the rope winding state on the coiling block based on the data matrix, and controlling an electric motor to drive the coiling block to lift heavy stuff when the rope winding state is a rope chaos state; and comparing the data matrix and a preset data matrix, and according to the compared result, executing at least one of the following operations: sending out a lifting hook over-hoisting signal, making a lifting mechanism decelerated and braking the lifting mechanism. According to the above technical scheme, the rope winding state on the coiling block and the position of the lifting hook can be determined by processing the images, and corresponding operations are executed for prevention on rope chaos and over hoisting.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a crane control method, a system, and a crane including the system. Background technique [0002] Existing tower cranes generally use double lifting mechanisms to lift objects. Each lifting mechanism is composed of a motor, a reel, and a wire rope. The double lifting mechanism drives a hook beam to lift and lower to lift objects. . [0003] However, during the actual working process of the crane, the hoisting mechanism is far away from the operator, and the operator cannot know the arrangement of the wire rope on the drum. In the process of arranging ropes, a huge impact load will be generated, and if accumulated for a long time, it will eventually lead to structural damage and wire rope breakage, which will lead to major safety accidents. [0004] In addition, the existing tower crane generally adopts a height limiter when preventing the hook from rushing to the top. The ...
