Embodiment Construction

[0032] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0033] Such as Figure 1-2 As shown, the winding type drum unwinding wire rope motion state recognition system of the present invention includes an industrial camera 1 installed on the rear and upper side of the drum 1 perpendicular to the drum axis and an industrial camera 2 3 installed on the right side of the drum 1 parallel to the drum axis. Due to the structure of the drum, the industrial camera 23 cannot capture the global longitudinal motion state of the ideal steel wire rope measuring point A at the tangent between the steel wire rope 4 and the drum 1. The distance between the actual wire rope measuring point B on the edge is extremely small compared with the distance between the drum 1 and the sky wheel, and the motion state of the actual wire rope measuring point B is basically the same as the motion state of the ideal wire rope measuring point A,...

Abstract

A system and method for identifying the motion status of a winding drum for winding and unwinding wire ropes, suitable for detecting the motion status of wire ropes in mine hoisting systems and elevator traction systems. The system includes an industrial camera, a wire rope axial speed measurement device and an industrial computer. The industrial computer receives the image signal captured by the industrial camera at the rope exit point of the drum and the axial movement speed signal of the wire rope collected by the shaft encoder to comprehensively monitor the movement status of the wire rope. Achieve comprehensive monitoring of drum roundness, drum wire rope tangle status and real-time speed of lifting containers. It realizes the visualization, automation and intelligence of the movement status monitoring of winding drum winding and unwinding wire rope. It has simple structure, convenient operation and good use effect.

Description

technical field [0001] The invention relates to a system and method for recognizing the motion state of a steel wire rope unwound by a winding drum, and is especially suitable for detection of the motion state of a steel wire rope in a mine hoisting system and an elevator traction system, and also for detection of the motion state of various steel wire ropes. Background technique [0002] The winding hoist is widely used in the mine hoisting system, and the running state of the wire rope on the winding drum is of great significance to the safe and efficient operation of the mine hoisting system. However, there is currently no effective way to identify the motion state of the steel wire rope unwound by the winding drum in real time, so that the roundness detection of the drum, the monitoring of the disordered wire rope of the drum, and the real-time speed of the lifting container cannot be known, burying hidden dangers for the safe and efficient production of coal mines. Con...
