Description

Technical Field

[0001] The utility model relates to a video monitoring device for detecting the de-groove of a crane wire rope. Background Art

[0002] In industrial production, wire ropes are important lifting and transmission equipment, and their operating conditions are directly related to production safety and efficiency. As the supporting and guiding component of the wire rope, the contact relationship between the crane and the wire rope is crucial to the normal operation of the wire rope. However, due to long-term use, wear, corrosion and other reasons, the wire rope may be out of the groove, that is, the contact between the wire rope and the crane is unstable, causing the wire rope to slip or jump when it is stressed. This situation will not only reduce the service life of the wire rope, but also may cause serious safety accidents. Therefore, timely and accurate detection of wire rope out of the groove failure is of great significance to ensure production safety and improve production efficiency.

[0003] Traditional wire rope de-groove detection methods mainly rely on mechanical contact or light waves. This method is not only inefficient, but also easily affected by many factors, leading to false detection and missed detection. With the development of computer vision technology, a new solution is provided for intelligent detection of de-groove. Summary of the invention

[0004] In order to realize intelligent detection of wire rope de-groove, the utility model provides a video monitoring device that performs intelligent analysis and judgment through image processing.

[0005] In order to achieve the above purpose, the technical solution provided by the utility model is as follows:

[0006] A video monitoring device for detecting de-slotting of a crane wire rope comprises a mounting bracket, a video monitoring camera and a fill light; there are two mounting brackets, which are respectively fixedly mounted on both sides of a wire rope drum; the video monitoring camera and the fill light are mounted on the mounting brackets and are located above the wire rope drum; the video monitoring camera adopts a high-definition network camera; and the fill light adopts an LED fill light.

[0007] Among them, the mounting bracket consists of an upper bracket and a lower bracket connected by adjusting bolts, and the whole is T-shaped; the lower bracket is vertically installed on the corresponding wire rope drum base by fixing screws; the video surveillance camera and fill light are installed on the upper bracket.

[0008] Furthermore, there are four video surveillance cameras (preferably 4 megapixels) and four fill lights (preferably 100 watts), which are correspondingly distributed above the two sides of the two wire rope drums.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] The utility model captures the images of daily operation of the wire rope by using a video monitoring camera, and uses a fill light to provide a lighting function to achieve a better imaging effect.

[0011] The device of the utility model can capture images in real time, so as to use the image processor to perform intelligent judgment and analysis, and can send out an alarm signal through the PLC, thereby timely discovering faults, reducing the loss of wire ropes, and extending the service life of the equipment.

[0015] In order to explain the problems to be solved and the technical advantages of the present invention more conveniently and in detail, the drawings and the specific examples therein will be described in detail below.

[0016] The embodiment of the utility model provides a video monitoring device for detecting the de-slotting of a crane wire rope, such as Figure 1 and Figure 2As shown, according to the size of the crane, the crane wire rope drum 6 has two, and there are slots in four positions to correspond to the corresponding rope pulling back. The mounting bracket 2 is T-shaped, consisting of an upper bracket and a lower bracket, and the upper bracket and the lower bracket are connected by a bracket adjustment bolt 11. The lower bracket is fixed to the drum base 9 by a bracket fixing bolt 1. The image processor 10 uses an Nvidia Jetson edge computing processor, the video surveillance camera 3 is a high-definition network camera, and the fill light 4 is an LED fill light. The three are installed on one side of the upper bracket of the mounting bracket 2 in sequence to detect the running status of the wire rope 5 on the wire rope drum 6. The entire device is connected to the drum bearing seat 8 through the bearing seat fixing bolt 7. Under the illumination of the LED fill light, the high-definition network camera transmits clear monitoring images to the Nvidia Jetson edge computing processor in real time to determine whether there is a groove-out phenomenon in the image. A T-shaped device (a mounting bracket equipped with an image processor, video surveillance camera and fill light) supports the identification and judgment of one or two points. Under correct circumstances, the ropes will be arranged in each adjacent slot in sequence. If the ropes in adjacent positions are not tightly arranged in their respective slots, they will be out of the slots.

[0017] The utility model can capture images through a video surveillance camera and transmit them to an image processor to automatically identify the state of the wire rope, thereby reducing manual intervention and improving detection efficiency, thereby realizing automatic detection. At the same time, the device is easy to install and can be extended to other wire rope detection tasks in similar scenarios.
