Abstract
Description
Technical Field
[0001] This application relates to the field of wire rope detection technology, and in particular to a visual data acquisition device for wire ropes of lifting equipment. Background Technology
[0002] Wire ropes, as crucial traction devices in lifting equipment, play a vital role in cargo handling and hoisting. However, they are prone to damage during use, such as broken wires and pitting corrosion. Accumulated damage can create serious safety hazards, endangering life and property. Currently, wire rope damage detection generally employs two methods: manual inspection and sensor detection. The former is inefficient and prone to missed detections and misjudgments, making it unsuitable for large-scale inspection tasks. The latter, utilizing electromagnetic detection and X-ray detection methods, while improving efficiency, is susceptible to environmental interference, cannot differentiate between damage types, and is also expensive, posing certain radiation hazards to human health.
[0003] With the rapid development of target detection algorithms, deep learning technology has shown great promise in the visual defect recognition of wire ropes in lifting machinery due to its advantages of automatic defect classification, high accuracy, and strong environmental adaptability. However, the quality of the acquired image data is often low due to the multiple wire ropes in the lifting equipment and the presence of poor lighting and interference in the environment.

[0021] The specific embodiments of this application are described in detail below with reference to the accompanying drawings.
[0022] One embodiment of this application provides a visual data acquisition device for wire ropes of lifting equipment, see reference. Figure 1-4 It includes a housing, at least one set of camera modules, and at least one set of pressure roller modules.
[0023] The housing has an internal space and a central through-hole. The housing comprises a left housing and a right housing, connected by a rotating connector and a locking mechanism. In this embodiment, the left and right housings are semi-circular, forming a complete circle when joined. The rotating connector between the left and right housings is a hinge. After opening the left and right housings, a detection wire rope can be inserted.
[0024] The camera module is housed within a casing and includes a CCD industrial camera and a fill light. Both the industrial camera and the fill light face the centerline of the central hole on the casing. The camera module also includes an adjustment device comprising a support, a slide, and an adjustment handle. The slide is slidably connected to the support, and the adjustment handle is mounted on the support. One end of the adjustment handle has a screw threadedly connected to the slide. The adjustment handle extends outside the casing, and the casing has an extension hole corresponding to the position of the adjustment handle. The CCD industrial camera is mounted on the slide, and the fill light is mounted on the slide via a lamp holder. The distance between the CCD industrial camera and the detected steel wire rope can be adjusted using the adjustment handle. When the steel wire rope detection aperture is too large, the slide can be adjusted to move radially inward; when the steel wire rope detection aperture is too small, the slide can be adjusted to move radially outward to accommodate steel wire ropes of different sizes.
[0025] The fill light is mounted above the CCD industrial camera via a lamp holder, and the fill light is facing the shooting direction of the CCD industrial camera. The fill light moves synchronously with the CCD industrial camera so that the fill light can always provide good illumination to the shooting direction.
[0026] In this embodiment, the camera module is provided in four groups, each group being evenly arranged inside the housing at 90° intervals.
[0027] The pressure roller module comprises two sets, respectively located on the upper and lower surfaces of the housing. Each pressure roller module includes a pair of wire rope pressure rollers. Each wire rope pressure roller includes a pressure roller base and a roller. The pressure roller base is rotatably connected to the housing, and a torque element is provided between the pressure roller base and the housing to bring the two wire rope pressure rollers within a set closer together to clamp the wire rope. The pressure roller module enables the device to be clamped onto the wire rope. Under external force, the device can crawl along the wire rope to acquire images of different locations.
[0028] The device is powered by a battery housed within the casing. Data acquired by the CCD industrial camera is stored locally or transmitted to a separate host computer or processing terminal via a communication module. In some other embodiments, power supply and communication are achieved via an umbilical cable.
[0029] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this application, and these all fall within the protection scope of this application.
