Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of subway vehicle monitoring, in particular to a pantograph mobile monitoring device for a subway vehicle. Background Art
[0002] The pantograph is an important electrical component of subway vehicles. It directly contacts the contact network and transmits the high-voltage current of the contact network to the high-voltage electrical equipment inside the subway vehicle, providing an energy source for the subway vehicle. With the rapid increase in the operating mileage of the subway, pantograph-network accidents occur from time to time, seriously affecting the operation order of urban rail. In order to avoid the operation of the pantograph with faults and improve the operation quality, it is necessary to monitor it in real time, which can not only detect the hidden dangers of the pantograph-network in time, but also provide effective data support for the continuous optimization of the pantograph-network relationship.
[0003] At present, the monitoring of pantographs of subway vehicles generally relies on image acquisition equipment. Image acquisition equipment, such as cameras and high-definition cameras, are deployed in the dynamic detection shed of the vehicle base to collect real-time images of the pantograph, so that monitoring personnel can understand the working status of the pantograph through image information and promptly detect abnormalities or failures of the pantograph. However, if the image acquisition equipment fails and needs to be repaired or replaced, since the image acquisition equipment is directly fixed on the top of the dynamic detection shed, the monitoring personnel need to climb up to operate, which is extremely inconvenient. In addition, the maintenance or replacement operations are generally carried out under the contact network, which is extremely unsafe for the monitoring personnel.
[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned defects. Summary of the invention
[0005] The utility model aims to provide a mobile monitoring device for a pantograph of a subway vehicle, so as to solve the problem of inconvenience in maintenance or replacement when an image acquisition device is directly fixedly installed in a dynamic detection shed of a vehicle base.

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", etc. should be understood in a broad sense, for example, it can be fixedly connected, set, or detachably connected, set, or integrally connected, set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] In a specific implementation manner, the line direction is defined as the longitudinal direction, and the direction perpendicular to the line direction is defined as the transverse direction.
[0036] The utility model provides a pantograph movement monitoring device for a subway vehicle, such as Figure 1 The device includes a door-type bracket 6 and an image acquisition device 4. The door-type bracket 6 is arranged above the subway vehicle 1. The image acquisition device 4 is installed on the top of the door-type bracket 6. The image acquisition device 4 faces the overhead line 2 and the pantograph 3 downward, and can collect image information of the pantograph 3 to timely discover abnormalities and failures of the pantograph 3. The image acquisition device 4 can be a camera or a high-definition camera.
[0037] like Figure 2 The portal bracket 6 includes a crossbeam 7 and legs 8 on both sides thereof. The crossbeam 7 is located above the contact network 2 and the pantograph 3. The legs 8 are located on both sides of the subway vehicle 2. Ladders 9 are provided on the longitudinal sides of the legs 8. The monitoring personnel can climb up to the top of the portal bracket 6 along the ladders 9 and perform operations at the lateral ends of the crossbeam 7.
[0038] like Figure 3-Figure 6 , a transversely arranged belt 10 and a slideway 13 are provided on the longitudinal side of the crossbeam 7. A longitudinal transmission shaft 11 is provided at both transverse ends of the crossbeam 7, and the belt 10 is installed on the transmission shafts 11 at both ends, and one of the transmission shafts 11 is associated with the output shaft of the servo motor 12 provided on the crossbeam 7. After the servo motor 12 is started, it drives the belt 10 to run. The slideway 13 is located below the belt 10 and is a transverse convex strip protruding outward.
[0039] The image acquisition device 4 is fixed on the base 14, which is fixed to the belt 10 and moves laterally along the slideway 13 under the traction of the belt 10. Specifically, a belt clip 15 is provided on the base 14, which is clamped on the belt 10 to allow the image acquisition device 4 to move synchronously with the belt 10. A T-shaped card slot 16 is provided on the base 14, which is clamped on the upper and lower sides of the transverse convex strip of the slideway 13, and plays a guiding role while installing the image acquisition device 4.
[0040] In some embodiments, the clamping surface of the belt clip 15 is also provided with anti-slip teeth to increase the friction between the belt 10 and the belt.
[0041] In some embodiments, protrusions are further provided on the upper and lower sides of the slideway 13, so that the cross-section of the transverse protrusion is T-shaped, and a groove is provided at the corresponding position of the T-shaped slot 16, and the protrusion is embedded in the groove. Such an embedding structure can prevent the base 14 from slipping off the slideway 13.
[0042] In addition, in order to accurately move the image acquisition device 4, a laser positioning device 5 is also provided in the transverse middle of the crossbeam 7, and a sensor that cooperates with the laser positioning device 5 for positioning is provided on the top of the base 14. When the image acquisition device 4 moves to the position of the laser positioning device 5, the servo motor 12 is stopped, the belt 10 no longer moves, and the image acquisition device 4 stays at the set position and starts working. The laser positioning device 5 uses an infrared sensor. Of course, other existing devices that can play the above role can also be used in the implementation of the utility model.
[0043] When the image acquisition device 4 needs to be repaired or replaced, the servo motor 12 is started, and the belt 10 drives the base 14 and the image acquisition device 4 to move horizontally to the end of the beam 7. The monitoring personnel reach the end of the beam 7 at the top of the leg 8 through the ladder 9 and directly operate. It is no longer necessary to work directly under the contact network, which is safer and more convenient. After the repair or replacement is completed, the belt 10 is used to move the image acquisition device 4 to the center, and with the cooperation of the laser positioning device 5 and the sensor, it automatically stops at the set position and starts working.
[0044] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of the present invention.
