description The utility model provides the improved rope box of the trolleybus. The utility model is characterized in that a rope disc and a ratchet wheel are arranged on a main shaft in equal intervals, and the rope disc and ratchet wheel can coaxially connect around the main shaft through a lock which is in riveted connection on the ratchet wheel. The line-dropping electrical signal controls the operation of an electric magnet in the rope box after the line of a current collector is dropped. The iron sucking rod of the electric magnet is extended out and is pushed a ratchet pawl mechanism which has the one-way braking function to contact a ratchet tooth, and the ratchet wheel is rapidly locked. Meanwhile, the rope disc is locked, and then the pull rope of the current collectors is stopped quitting. Thus, the climbing height of the current collectors is rigidly controlled in less than 15 centimeters after the line of the current collector is dropped.
