The invention relates to the field of building mechanical equipment, in particular to a building crane protection device which comprises a cross beam, a first pulley and a winch are installed on the bottom face of the cross beam, a telescopic device is installed on the top face of the cross beam, the power output end of the telescopic device is connected with a first fixing block, and the first fixing block is connected with a second fixing block. The first fixing block and the second fixing block are connected in a sliding mode. The first pulley and the winch are respectively connected with the second fixing block; a balancing weight is arranged on the bottom face of the cross beam and located between the first pulley and the winch. When the distance between the first fixing block and the second fixing block is closest, the bottom end of the balancing weight is higher than the top end of the first pulley wheel disc or is as high as the top end of the first pulley wheel disc; and when the distance between the first fixing block and the second fixing block is farthest, the bottom end of the balancing weight is lower than the top end of the first pulley wheel disc. The device can prevent overload operation of the crane.

    本发明涉及建筑机械设备领域,具体为一种建筑用起重机保护装置,包括横梁,横梁的底面安装有第一滑轮和卷扬机,横梁的顶面安装有伸缩装置,伸缩装置的动力输出端连接有第一固定块,第一固定块连接有第二固定块,所述第一固定块和所述第二固定块滑动连接;所述第一滑轮和卷扬机分别与所述第二固定块连接;所述横梁的底面设置有配重块,所述配重块位于所述第一滑轮和卷扬机之间;当所述第一固定块和第二固定块之间的距离最近时,所述配重块的底端高于所述第一滑轮轮盘的顶端或者与所述第一滑轮轮盘的顶端高度相同;当所述第一固定块和第二固定块之间的距离最远时,所述配重块的底端底于所述第一滑轮轮盘的顶端。该装置可防止起重机超负荷运行。
