The invention discloses a self-detachable flat arm crane which comprises a tower body, a tower cap arranged above the tower body, and a large arm and a balance arm which are arranged on two sides of the tower body, the top end of the tower cap is connected with the large arm and the balance arm through a pull plate, a hoisting trolley is arranged on the large arm, and a counterweight trolley is arranged on the balance arm. The balance arm is further provided with a winch used for winding a main steel wire rope, a pulley used for guiding the main steel wire rope and a steel wire rope hoisting mechanism used for hoisting the large arm. The large arm is provided with an auxiliary steel wire rope used for assisting the large arm in disassembling. The ground is further provided with an auxiliary winch used for assisting disassembly of the large arm and a ground pull rope connected with the auxiliary winch and the large arm. According to the invention, the large arm is disassembled section by section through the combined introduction of the steel wire rope, the winch, the tower top pulley and other components, so that the maintenance and replacement of each part can be relatively independently carried out, a crane on the ground does not need to be additionally erected, and sectional disassembly is directly carried out on the tower crane, so that the maintenance cost and the working difficulty are reduced.

    本发明公开了一种可自拆的平臂吊,包括塔身、设于塔身上方的塔帽、设于塔身两侧的大臂和平衡臂,塔帽的顶端通过拉板连接大臂和平衡臂,大臂上设有吊装小车,平衡臂上设有配重小车,平衡臂上还设有用于卷绕主钢丝绳的卷扬机、用于主钢丝绳导向的滑轮以及用于吊装大臂的吊装钢丝绳机构;大臂上设有用于辅助大臂拆卸的辅助钢丝绳;地面上还设有用于辅助大臂拆卸用的辅助卷扬机以及连接辅助卷扬机和大臂的地面拉绳。本发明通过钢丝绳、卷扬机、塔顶滑轮等构件的联合引用,将大臂逐节拆卸,使各部分的维护和更换可以相对独立地进行,不用另外架起地面的起重机,直接在塔机上进行分段拆解,降低了维护成本和工作难度。
