Windlass steel cable detection device and method

Abstract

The invention provides a windlass steel cable detection device. The windlass steel cable detection device comprises an image collection unit which is installed on the front surface of a windlass steel cable, wherein the image collection unit comprises an imaging instrument, an upper laser and a lower laser, the imaging instrument is arranged between the upper laser and the lower laser and a distance is kept between the imaging instrument and the steel cable, the imaging instrument is provided with a lens and adopts the steel cable as a collection target, the upper laser and the lower laser are identical components and arranged in front of and behind the lens, the upper laser and the lower laser are respectively provided with a luminescent hole, each luminescent hole faces the imaging instrument collection target by forming an angle with the target, a light curtain projected by each luminescent hole is overlapped with an imaging instrument collection target area to form an overlapped area, and the overlapped area is a spot area. By adopting the structure, the technical problems of error in judgment and judgment by mistake caused by collecting abnormal light spots can be solved, so that a good effect for improving the accuracy in detection can be realized.

Description

technical field [0001] The invention relates to the technical field of operation transportation, in particular to a hoist wire cable detection device and a method thereof. Background technique [0002] The steel cable integrity detection method of prior art has: [0003] 1. The contact type steel cable integrity detection method is difficult to construct, and the contact installation of the steel cable will cause an additional failure point for the steel cable. [0004] 2. The non-contact steel cable integrity detection method generally uses the photoelectric cross-beam shielding type. The photoelectric cross-beam type needs to be installed about 10 cm away from the steel cable, which also poses a threat to the normal operation of the steel cable. Contents of the invention [0005] In order to solve the above technical problems, the main purpose of the present invention is to provide a hoist wire cable detection device and method thereof that can improve detection accurac...
