The invention discloses a tower crane capable of quickly disassembling and assembling a counterweight block, and relates to a building engineering machinery. A lifting arm and a balance arm are arranged on a rotating table, and are opposite in position; a counterweight lifting device is arranged at the inner top of a jacking sleeve frame, and can vertically move in a standard joint; a counterweight slide way fitting the counterweight lifting device is arranged on the balance arm; a fixing device for fixing a counterweight block is arranged on the balance arm; a limiting guide groove is formed in the jacking sleeve frame; an opening of the limiting guide groove is a bell mouth; a guide bar fitting the limiting guide groove is arranged at the top of the standard joint; and a matched groove fitting the guide bar is arranged at the bottom of the standard joint. Compared with the prior art, the tower crane can quickly install and disassemble the counterweight block, can quickly disassemble the counterweight block to keep the gravity center of the crane stable in the coming of typhoon or in other gale states, and solves the problems of need of a crane to install the counterweight block, low installation efficiency, slow speed and difficult alignment in the installation of the standard joint in the prior art.
