The invention belongs to the technical field of hoisting equipment, and discloses a tower crane for building extension, which comprises a guide rail moving mechanism, a top climbing protection ladder mechanism, a main and auxiliary hook lifting platform and a main body, and is characterized in that the guide rail moving mechanism is positioned at the bottom of the main body, and the top climbing protection ladder mechanism is fixedly mounted on the outer wall of the guide rail moving mechanism; the main and auxiliary hook lifting platform is fixedly mounted at the top of the guide rail moving mechanism; the guide rail moving mechanism comprises two guide rail tracks, the tower crane traveling crane is locked on the guide rail tracks through cooperation of locking bolts and concave rail clamping devices, the tower crane traveling crane is moved to the locking position, the locking bolts on the left side and the right side of the sliding rail cart are manually unscrewed, the concave rail clamping devices are released from limitation in sliding grooves, and the tower crane traveling crane is moved to the locking position. When the tower crane is taken out, one end of the tower crane is inserted into the lower end of the sliding groove, the other end of the tower crane is inserted into the corresponding rail clamping groove, all the locking bolts are tightened, the tower crane is locked, and accidents caused by blowing of the tower crane in windy days are prevented.

    本发明属于起重设备技术领域,且公开了一种建筑扩建用塔吊行车,包括导轨移动机构、登顶护梯机构、主副钩起落台和主体,其特征在于:所述导轨移动机构位于主体的底部,所述登顶护梯机构固定安装于导轨移动机构的外壁,所述主副钩起落台固定安装于导轨移动机构的顶部;所述导轨移动机构包括导轨轨道,所述导轨轨道的数量设置为两个,通过锁紧螺栓和凹型夹轨器的配合,将塔吊行车锁死在导轨轨道上,将塔吊行车移动到锁死位置,手动拧松滑轨大车左右两侧的锁紧螺栓,凹型夹轨器在滑行槽中解除限制,将其拿出把一端插入滑行槽的下端,另一端插入对应的夹轨槽中,拧紧全部锁紧螺栓,塔吊行车即被锁死,防止大风天吹动塔吊行车造成事故。
