Problems solved by technology
[0004] At present, the existing power-taking device is mainly composed of a guide frame, a guide post, an insulating plate and a grinding block, and the guide post is set at a right angle to the conductive rail. When the interface of the guide rail, or the surface of the conductive rail is uneven due to deformation, wear and other reasons, it is easy to cause poor power supply of the grinding block or collision with the rail. What's more, the conductive rails arranged on the rotating platform are all set in the way of rubber insulation. , so the surface of the conductive rail on the rotating platform and the conductive rail on the ground are more likely to be uneven, and the above-mentioned problems are very likely to occur. The operation reliability of the power-taking device directly affects the production operation

The invention relates to the technical field of power supplies, and particularly relates to a rail-changing electricity-taking device of a low-voltage flat car. The device comprises a flat car body, a guide pillar sleeve, a movable guide pillar, a first grinding electric block and a second grinding electric block. The guide pillar sleeve comprises a sleeve body, a first connecting part and a second connecting part, and the first connecting part and the second connecting part are connected to the two sides of the sleeve body respectively. One end of the movable guide pillar is elastically connected in the sleeve body, and the other end extends out of the sleeve body. The first grinding electric block is elastically connected to the first connecting part and rotatably connected to the movable guide pillar. The second grinding electric block is elastically connected to the second connecting part and is rotatably connected to the movable guide pillar. By arranging the first grinding electric block and the second grinding electric block, the rail- changing electricity-taking device of the low-voltage flat car can be applied to a scraggly conductive rail or two conductive rails which are not connected when the rails are changed through a rotating table, and an electricity taking effect is guaranteed.
Description
technical field [0001] The present application relates to the technical field of power supplies, and in particular, to a rail-swapping power-taking device and system for a low-voltage flatbed vehicle. Background technique [0002] At present, most workshops are equipped with low-voltage electric flatbed trucks, and low-voltage electric flatbed trucks are used for material transfer. There are usually multiple conductive rails in the workshop. When the low-voltage electric flatbed truck is transported in different directions, the rails need to be converted. The transfer track is generally realized by rotating the platform. [0003] The power take-off device is the core part of the low-voltage rail-powered electric flatbed car. It feeds the low-voltage power to the step-up transformer on the car body through the power-taking grinding block, and then the step-up transformer raises the low voltage to the rated voltage and supplies the drive of the flat car. motor. Therefore, i...
