Technical Field
[0001] The utility model relates to a current collector guiding device for a sliding contact wire. Background Art
[0002] Due to movement, mobile devices need to constantly change their positions. At each different position, the mobile devices also need to be able to obtain power supplies at any time, otherwise they cannot continue to move. At this time, the sliding contact wire was invented and created. A number of conductors are laid parallel to the running track of the mobile device, and the power supply is connected. A current collector that can draw electricity from the conductors is installed on the moving device, and the carbon brush of the current collector contacts the conductor through a guiding device. In this way, when the device moves, the current collector runs synchronously with the mobile device and obtains power from the conductor at any time to supply the device so that the device can continue to move.
[0003] In the prior art, due to different travel limits of mobile devices and different extension heights of current collectors, when the carbon brush of the current collector travels to the guiding device for guiding power taking, because the height of the carbon brush is too high and the height of the guiding device in the vertical direction is not adjustable, the carbon brush collides with the guiding device, causing damage to the device; and the guiding device in the prior art does not have a buffering function. When the mobile device travels at a high speed, the carbon brush of the current collector rigidly contacts the guiding device, resulting in damage to the current collector.
[0004] Therefore, there is an urgent need for a current collector guiding device for a sliding contact wire that has strong adaptability, can adapt to different limits of mobile devices and different extension heights of current collectors, and has a buffering function to solve the problems existing in the prior art.
