The invention discloses an anchoring trolley with a rope breakage protection function for a tower crane. The tower crane comprises an inverted triangular arm frame, a trolley body and a luffing mechanism, wherein the trolley body and the luffing mechanism are installed on the inverted triangular arm frame. The triangular arm frame is provided with a plurality of web members; the trolley moves back and forth on the inverted triangular arm frame through a luffing mechanism, and the luffing mechanism comprises a luffing steel wire rope I fixed at the front end of the trolley and a luffing steel wire rope II fixed at the rear end of the trolley; comprising a broken rope protection stop lever installed on a trolley. The broken rope protection stop levers are respectively arranged at the front end and the rear end of the trolley and are respectively connected with the variable-amplitude steel wire rope I at the front end and the variable-amplitude steel wire rope II at the rear end through chains; and when the variable-amplitude steel wire rope I or the variable-amplitude steel wire rope II is broken, the broken rope protection stop lever is inserted into the web member of the triangular arm frame to stop the trolley from continuously moving. The device is simple in overall structural form, convenient to produce and process and easy to implement; installation and use are convenient, operation is easy, and time and labor are saved.
