Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0022] A current collector with a detachment from the three-rail device, see figure 1 , 2 , including backplane 1, fuse box 2 and current receiver body 3. A locking mechanism is provided between the receiver body 3 and the back plate 1 , and the locking mechanism is composed of a rotating shaft 10 , a locking hook 7 , a locking plate 9 and a leaf spring 6 . The locking hook 7 is connected with the rotating shaft 10 , one end of the leaf spring 6 is mounted on the backboard 1 , and the other end presses the locking plate 9 , and one end of the locking plate 9 is connected with the backboard 1 . Such as image 3 As shown, when it is necessary to run away from the third rail or the vehicle enters the warehouse to replace the carbon slider 12, the shoe-off handle 11 can be used to apply force to the connection between the swing arm 5 and the carbon slider 12, and the l...

Abstract

The invention discloses a current collector with a device capable of breaking away from a third rail, which belongs to the field of current collectors and is used for solving the problem that the installation and the maintenance of a conventional current collector are not convenient. The current collector with the device capable of breaking away from the third rail comprises a fuse protector box, a current collector body and a back plate for connecting the fuse protector box and the current collector body, wherein a locking mechanism for locking the current collector body on the back plate is arranged between the current collector body and the back plate. When some current collectors go wrong, the current collector can break away from the third rail and run and a carbon sliding block is conveniently replaced to ensure that the hidden danger of arc discharge to a bogie is eliminated. The current collector disclosed by the invention has the advantages of small volume, convenience for installation and use and reliability in performance.

Description

technical field [0001] The invention relates to a third-rail current collector for rail transit vehicles, in particular to a current collector with a three-rail detachment device. Background technique [0002] At present, the third-rail current collectors used in existing rail vehicles are affected by many factors, such as external environmental conditions, the slope and surface condition of the elbow at the end of the third rail, the state of current collection, the movement of the vehicle, and electrical insulation. Wait. When some current collectors are abnormal, it is necessary to take off the boots of this part of the current collectors to prevent the occurrence of arc discharge. When the current collector needs to be overhauled or the carbon slider needs to be replaced, a certain distance is required between the current collector and the third rail, which requires the cooperation of multiple people and is very inconvenient for installation and maintenance.
