Description

Technical Field

[0001] The utility model relates to the technical field of pantograph detection, in particular to a pantograph detection device. Background Art

[0002] As is well known, the pantograph carbon slide is an indispensable component in the electrified railway system. Its main function is to ensure that the locomotive can stably obtain electrical energy from the catenary to drive the operation. However, due to various reasons such as friction with the catenary, vehicle load and contact line factors, and mechanical force imbalance, the carbon slide will wear during use. This wear not only affects the transmission efficiency and quality of electrical energy, but also may endanger the operational safety of the vehicle.

[0003] Traditional monitoring methods mostly rely on manual visual inspection, which is not only inefficient but also has many limitations. Manual visual inspection often relies on the inspector's experience and visual acuity, which is highly subjective and may lead to misjudgment or omission of the degree of wear.

[0004] A Chinese patent (publication number: CN117557533A) discloses a method, system, electronic device and medium for monitoring the wear of a pantograph carbon skateboard. The patent prints a wear indicator strip on the side end of the pantograph carbon skateboard, and sets camera-related hardware capable of collecting skateboard images and color data. An initial wear estimate of the pantograph carbon skateboard is obtained through a trained machine learning model, and the skateboard image of the side end of the pantograph carbon skateboard and the color data matching the skateboard image are combined to achieve real-time monitoring of the pantograph carbon skateboard wear. The initial wear estimate is calibrated with the color data to obtain the total wear of the pantograph carbon skateboard without manual judgment, thereby eliminating the subjectivity of wear monitoring in traditional methods. However, in actual application, it was found that the patent was easily affected by the surrounding environment when collecting images, resulting in difficulty in analyzing the collected images and low detection accuracy.

[0023] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", and "right" indicating directions or positional relationships, they are only corresponding to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0024] Example 1, combined with the attached Figures 1 to 5 A pantograph detection device detects the wear of the pantograph carbon slide plate 1 through a visual detection system. The visual detection system includes a camera 2 and a light source 3. That is, the visual detection system takes a static photograph of the pantograph carbon slide plate 1 for detection, and analyzes the wear of the pantograph carbon slide plate 1 based on the captured image. Since the visual detection system is an existing mature technology, its working principle will not be described in detail in this embodiment;

[0025] It also includes a floating mechanism 5 and a light shield 4 that can be covered outside the pantograph. The light shield 4 can block ambient light and reduce the detection difficulty of the visual detection system; the bottom of the light shield 4 is open, and a light source 3 is provided on one side of the light shield 4 and a camera 2 is provided on the other side; guide plates 6 are provided at both ends of the light shield 4, and the guide plates 6 are provided with guide grooves, as shown in the attached figure. Figure 4 As shown; the top of the sunshade 4 is provided with a floating mechanism 5 that enables the sunshade 4 to float back and forth;

[0026] During inspection, the pantograph is controlled to rise and extend into the guide slot of the guide plate 6. The guide plate 6 drives the light shield 4 to float back and forth through the floating mechanism 5, automatically adapting to the position of the pantograph. This allows the pantograph carbon slide plate 1 to automatically locate at the corresponding position between the visual inspection system camera 2 and the light source 3, ensuring that the visual inspection system can accurately capture and inspect.

[0027] Combined with attachment Figure 2The floating mechanism 5 includes an H-shaped floating frame 5-1, and guide shafts 5-2 are provided at both ends of the floating frame 5-1. The sliding sleeve of the guide shaft 5-2 is provided with a sliding sleeve 5-3. The sliding sleeve 5-3 is fastened to the top of the light shield 4. The two ends of the guide shaft 5-2 corresponding to the sliding sleeve 5-3 are sleeved with springs 5-4. That is, during the pantograph raising process, the guide plate 6 drives the light shield 4, and the light shield 4 drives the sliding sleeve 5-3 to slide along the guide shaft 5-2, automatically adapting to the position of the pantograph; after the detection is completed, the pantograph is lowered, and the sliding sleeve 5-3 drives the light shield 4 to the center under the action of the spring 5-4, so as to facilitate the detection of the next pantograph carbon slide 1;

[0028] When using, combine with Figure 5 , set up the floating mechanism 5 above the locomotive track. When it is necessary to detect the wear of the pantograph carbon slide 1, make the locomotive travel to the bottom of the light shield 4, control the pantograph to raise the pantograph, and extend the pantograph carbon slide 1 into the guide groove of the guide plate 6, so that the light shield 4 automatically adapts to the position of the pantograph. Then, the pantograph carbon slide 1 can be photographed and inspected by the visual inspection system, and the wear of the pantograph carbon slide 1 can be analyzed through the captured images.

[0029] Example 2, combined with the attached Figure 6 A pantograph detection device is different from Example 1 in that, based on Example 1, a fixing frame 7 is provided above the floating mechanism 5, and the fixing frame 7 is equipped with a telescopic cylinder 8 for driving the floating mechanism 5 to rise and fall, that is, the light shield 4 and the floating mechanism 5 can be erected above the locomotive track through the fixing frame 7; when it is necessary to detect the wear of the pantograph carbon slide 1, the telescopic cylinder 8 is controlled to extend to cause the light shield 4 to descend and cover the outside of the pantograph; during the descent of the light shield 4, the floating mechanism 5 enables the guide plate 6 to drive the light shield 4 to float back and forth, automatically adapting to the position of the pantograph without the need to raise the pantograph;

[0030] The floating frame 5-1 is provided with guide posts 9 on both sides of the telescopic cylinder 8, which are movable and pass through the fixed frame 7. The guide posts 9 provide guidance, which can effectively ensure the stability of the lifting of the light shield 4.

[0031] A pressure sensor 10 is provided between the telescopic cylinder 8 and the floating frame 5-1. During the descent of the light shield 4, the pressure applied to the light shield 4 can be detected in real time through the pressure sensor 10, ensuring that the pantograph carbon slide plate 1 enters the bottom of the guide groove of the guide plate 6, while preventing a large pressure from being applied to the pantograph.

[0032] Example 3, combined with the attached Figure 1, a pantograph detection device, based on embodiment 1 or 2, a light shielding plate 11 that can contact the top of the pantograph carbon slide plate 1 is provided at a position corresponding to the two guide plates 6 in the light shield 4, that is, when performing detection, the light shielding plate 11 can be made to fit correspondingly with the top of the pantograph carbon slide plate 1. After the light source 3 is turned on, light will leak from the worn part of the pantograph carbon slide plate 1. The wear condition of the pantograph carbon slide plate 1 is judged based on the light leakage condition, which is conducive to the visual detection system to quickly identify and analyze the wear condition of the pantograph carbon slide plate 1.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
