Description

Technical Field

[0001] The invention belongs to the technical field of nondestructive testing of oil and gas equipment, and in particular relates to a wire rope group damage detection device for an offshore drilling platform hoist. Background Art

[0002] As an important component of the offshore drilling platform hoist, the wire rope group is specifically used to support and bear the dynamic load during the lifting and traction process of the offshore drilling platform hoist. Therefore, non-destructive testing research on the wire rope group has far-reaching significance for ensuring its safe use and preventing major accidents.

[0003] The existing non-destructive testing technologies for wire rope groups include at least the following categories: ultrasonic testing technology, X-ray testing technology, acoustic emission testing technology, eddy current testing technology, electromagnetic testing technology, mechanical testing technology, acoustic testing technology, current testing technology, optical testing technology, vibration testing technology, visual testing technology, etc. Among them, with the rapid development of artificial intelligence technology, visual testing technology has gradually been incorporated into the scope of non-destructive testing of wire rope groups. It is worth noting that the visual testing technology of wire rope groups is a comprehensive testing method that integrates high-definition video and computer vision algorithms. This visual testing technology uses high-definition cameras and other sophisticated visual auxiliary equipment to capture every subtle image information of the wire rope group in real time and clearly during operation. By using computer vision algorithms, the above image information will be deeply analyzed and finely processed, so as to accurately identify various damages and defects on the surface of the wire rope group, including but not limited to subtle broken wires, corrosive rust marks, and wear caused by long-term use. This technology not only cleverly combines the intuitiveness of high-definition camera technology and the precision of image processing technology, but also realizes the real-time collection, in-depth analysis, intelligent early warning and efficient storage of wire rope group damage information, providing strong technical guarantee for the safe use of wire rope groups.

[0004] However, after further research, the inventors found that the existing visual inspection device for hoist wire rope groups does not provide a good solution for the visual blind spot (generated during the visual inspection of multiple wire ropes). It is worth noting that a large number of field experiments have shown that in order to accurately identify the defects of the wire rope group, good lighting conditions are a necessary condition to ensure the detection effect. Especially in the scenario of multiple wire rope groups of offshore drilling platform hoists, how to overcome the problem of detection area occlusion and light reflection during the collaborative inspection of multiple wire rope groups has become a technical problem that technicians in this field need to solve urgently.

[0016] The present invention provides a wire rope group damage detection device for an offshore drilling platform hoist. The detection device comprises a camera detection unit and a lighting unit, which provides a better lighting environment for the wire rope group of the offshore drilling platform hoist; and further increases the surface capture range of the wire rope group, reduces the visual dead zone during the wire rope group detection process, thereby adapting to the visual detection requirements of wire rope groups of different sizes under different arrangements and combinations.

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The present invention provides a device for detecting damage of a wire rope group for an offshore drilling platform hoist. Figure 1 As shown, it includes: an upper shell 1, a lower shell 2, a lighting unit and a camera detection unit. Figure 2 As shown, the upper shell 1 and the lower shell 2 are connected to form an integral structure through a spring fastening buckle 4 (the spring fastening buckle 4 is installed at the outer side wall 3 of the upper shell 1 and the lower shell 2).

[0019] It is worth noting that, as a preferred embodiment of the present invention, considering the dynamic deviation that may occur in the detection process of the steel wire rope group 6, a baffle 5 is further provided on the side of the upper shell 1 and the lower shell 2 in the detection inlet direction and the detection outlet direction, and the baffle 5 is further provided with an opening for the steel wire rope group 6 to be detected to pass through, as shown in FIG. Figure 3 , Figure 4 As shown, the space redundancy of the baffle and the opening design can buffer the deviation problem of unstable movement caused by the traction wire rope group.

[0020] like Figure 5 As shown, the lighting unit is composed of a plurality of LED light groups 10, and each LED light group 10 is provided with a plurality of LED lamp heads. Among them, the LED light groups 10 are provided in a one-to-one correspondence with the LED light group brackets 18, and the plurality of LED light group brackets 18 are fixedly provided in the LED light group support seat 9 (when the LED light group brackets 18 are installed and connected with the LED light group support seat 9, they can be fixed by nuts; in addition, the support seat preferably adopts a lightweight design, which reduces the overall weight while ensuring that its supporting strength is not affected). Figure 6 As shown, the LED lamp group support base 9 is installed on the LED lamp group fixed top plate 7 (through the LED lamp group support base fixing screws 17), and the LED lamp group fixed top plate 7 is arranged at the top surface position inside the upper shell 1.

[0021] It is worth noting that the LED light group 10 is used as the main light system to provide as large an area of ​​lighting conditions as possible for the steel wire rope group 6 to be detected. Figure 7 As shown, wedge-shaped ear plates are also designed on both sides of the LED light group bracket 18, and through holes are set on the ear plates; and rotating shafts are correspondingly designed on both sides of the LED light group 10. Through the mutual cooperation of the rotating shaft and the through hole, the rotation connection and cooperation between the LED light group 10 and the LED light group bracket 18 are realized, so as to further facilitate the LED light group 10 to adjust its incident angle according to the rope diameter and arrangement position of different steel wire rope groups, so as to achieve the optimal lighting conditions.

[0022] like Figure 8 As shown, the video detection unit is composed of a plurality of cameras 15. It is worth noting that the camera 15, as an image capture structure, is mainly used to collect surface information directly above the wire rope group and to collect gap arc surface information of the wire rope group. Among them, in order to obtain the best image capture effect, a plurality of cameras 15 are installed on the arc-shaped mounting plate 8 in a manner of multiple rows and parallel distribution, and the arc-shaped mounting plate 8 is selected to be arranged inside the upper shell 1, directly above the wire rope group 6 to be detected. In addition, considering that the surface of the wire rope group is an arc surface, an LED light strip 14 can be further preferably arranged around the arc-shaped mounting plate 8, so as to reduce the light blind spot problem directly above the wire rope group.

[0023] For example, refer to Figure 8 As shown, the number of the steel wire rope group 6 to be detected is 5 (arranged), the rope diameter of a single steel wire rope group is about 8mm, and the rope center spacing is about 12mm; at this time, the angles of the configured camera array are 22.5° and 45° respectively. Through the above arc array setting, the camera array unit can effectively capture the surface information directly above the arc array, and can also obtain the surface information of the arc surface of the rope group gap.

[0025] One thing that needs to be added is that Fig.10 As shown, the reflector 11 is fixedly mounted on the reflector support frame 12. Through the hemispherical groove, the reflector support frame 12 is rotatably connected and matched with the ball support seat 13. The ball support seat 13 is mounted (through the ball support seat fixing screw 16) at the side position of the non-detection entrance direction and the non-detection exit direction of the upper shell 1.
