Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, and more particularly to a rail transportation vehicle shoe rail detection device. Background Art

[0002] The shoe-rail system refers to the combination of a collector shoe and a contact rail, where "shoe" refers to the collector shoe and "rail" refers to the contact rail. The collector shoe is a current-collecting device installed on the bogie of an electric train, while the contact rail is a power supply device installed on the ground next to the track. The contact interface between the collector shoe and the contact rail not only restricts the train's running speed, but also affects the stability of the power supply. Good contact is a prerequisite for the stable operation of the train. In the subway traction power supply system, the shoe-rail system undertakes the important task of providing energy to the train, and its coupling state is directly related to the reliable operation of the train.

[0003] In the prior art, the patent with publication number CN208248210U discloses a shoe rail detection device, comprising: a camera packaging module installed at the bottom of the vehicle body, comprising a shell and a collector shoe monitoring camera and a grounding shoe monitoring camera arranged in the shell, a switch arranged on the vehicle body, and communicatively connected with the monitoring camera, for storing and forwarding the collector shoe image taken by the monitoring camera and the grounding shoe image taken by the grounding shoe monitoring camera; a main control server is communicatively connected with the switch, for receiving the collector shoe image and the grounding shoe image forwarded by the switch; the collector shoe and the grounding shoe are respectively monitored in real time by the collector shoe monitoring camera and the grounding shoe monitoring camera, and then the operator or the main control server can identify the abnormal state of the collector shoe graphic and / or the grounding shoe image being off, so that the fault can be detected in time, and the fault area can be alarmed immediately, thereby reducing the reaction time of the detection personnel, and being able to handle the fault in advance, effectively preventing the occurrence of more dangerous accidents caused by this fault.

[0004] In the shoe rail inspection device disclosed in the aforementioned patent, each camera package module is installed on the bottom of a train section. Limited by the shooting angle of a single camera, it cannot capture the shoe rail from multiple perspectives, resulting in some angles not being captured, thereby reducing detection accuracy.

[0022] The following will provide a clear and complete description of the concept, specific structure and technical effects of the present invention in conjunction with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present invention.

[0023] A rail transit vehicle shoe rail detection device, such as Figure 1 As shown, it includes a main beam 1, a vehicle body mounting seat 2, an arc camera 3 and a shoe rail camera 4;

[0024] The vehicle body mounting brackets 2 are mounted on the left and right ends of the main beam 1 and extend upward to connect to the vehicle body. Arc cameras 3 are mounted below the left and right ends of the main beam 1 to capture arcing. Multiple shoe rail cameras 4 are provided and all mounted below the main beam 1. These multiple shoe rail cameras 4 capture the shoe rail at different angles. A controller is also included and is electrically connected to the arc cameras 3 and shoe rail cameras 4.

[0025] In this embodiment, the vehicle body mounting brackets 2 are mounted on the left and right ends of the main beam 1 and extend upward to connect with the vehicle body. This means that the shoe rail detection device of the present invention is mounted on the vehicle body, allowing the vehicle body to drive the shoe rail detection device for shoe rail detection. The arcing camera 3 captures shoe rail arcing images, while the shoe rail camera 4 captures shoe rail contact images. These images are sent to a controller, which analyzes them to detect shoe rail arcing and shoe rail contact.

[0026] In this embodiment, multiple shoe rail cameras 4 are provided, and the multiple shoe rail cameras 4 shoot the shoe rail at different shooting angles. The shoe rail is shot at different angles by using multiple shoe rail cameras 4 at different angles to detect the contact status of the shoe rail in all directions and improve the detection accuracy.

[0027] like Figure 1 As shown, a junction box 5 is provided in the middle of the main beam 1. Wires are provided in the junction box 5. The wires pass through the junction box 5 and connect to the arc camera 3 and the shoe rail camera 4. The wires are used to power the arc camera 3 and the shoe rail camera 4 and transmit data. The junction box 5 is used to divide the wires.

[0028] like Figure 1As shown, the vehicle body mounting seat 2, the arc camera 3 and the shoe rail camera 4 are symmetrically assembled on the main beam 1 to shoot the left and right shoe rails. The arrangement is beautiful and practical.

[0029] like Figure 1 As shown, six shoe-track cameras 4 are provided: two symmetrically arranged horizontal shoe-track cameras, two symmetrically arranged tilted shoe-track cameras, and two symmetrically arranged vertical shoe-track cameras perpendicular to the tilted shoe-track cameras. The horizontal shoe-track cameras have their shooting ends facing horizontally to the left or right, while the tilted and vertical shoe-track cameras have their shooting ends tilted downward and at different angles. In other words, six shoe-track cameras 4 at different angles capture the shoe-track at six different angles, enabling comprehensive detection of the shoe-track's contact status.

[0030] like Figure 1 As shown, the main beam 1 includes a main cross beam 11, an arc camera mounting seat 12 and a shoe rail camera mounting seat 13; two main cross beams 11 are horizontally arranged, the vehicle body mounting seat 2 is assembled on the left and right ends of the two main cross beams 11 and extends upward, the arc camera mounting seat 12 and the shoe rail camera mounting seat 13 are assembled under the two main cross beams 11 and extend downward, the arc camera 3 and the shoe rail camera 4 are respectively assembled on the arc camera mounting seat 12 and the shoe rail camera mounting seat 13.

[0031] Conventional technology involves cameras mounted on the crossbeams of the vehicle's underbody frame. This heavy structure not only increases vehicle weight but also potentially increases energy consumption and maintenance costs. Furthermore, the heavy structure can limit the vehicle's acceleration and braking performance, impacting operational efficiency.

[0032] In this embodiment, the main beam 1, vehicle mounting base 2, and junction box 5 are all made of lightweight alloys. The main beam 1, vehicle mounting base 2, and junction box 5 are all made of lightweight aluminum-magnesium alloys. Using lightweight alloys instead of traditional steel reduces the overall weight of the subway vehicle shoe rail detection system, effectively improving the operating efficiency and energy efficiency of subway vehicles without sacrificing safety or detection accuracy. Furthermore, topology optimization can be employed to remove non-load-bearing components and retain only key structural components, achieving a lightweight structure.

[0033] The above is a detailed description of the implementation methods of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalents or substitutions are all included in the scope defined by the claims of the present invention.
