The invention discloses a building roof frame crane for building construction. The building roof frame crane comprises a bottom plate, a stand column is fixedly arranged in the middle of the upper endof the bottom plate, a workbench is movably arranged at the upper end of the stand column through a rotating shaft, a mounting plate is fixedly arranged on one side of the upper end of the workbench,a supporting pipe is fixedly arranged on one side, far away from the mounting plate, of the upper end of the workbench, a wire spool is movably arranged in the middle of the upper end of the mountingplate through a rotating shaft, a connecting rope is wound on the surface of the outer side of the wire spool, a motor is fixedly arranged at the position, on one side of the wire spool, of the upperend of the mounting plate through a mounting base, and the output shaft end of the motor is in transmission connection with the rotating shaft where the wire spool is located through a coupler. The building roof frame crane is good in using effect, the connecting rope can be rapidly and automatically locked in the event of an accident such as a power failure, and therefore danger can be prevented; and meanwhile, the connecting rope can be automatically locked when the descending speed of the connecting rope is too fast without power failure, and therefore the safety of the device during use is improved.

    本发明公开了一种建筑施工用楼顶架吊机,包括底板,所述底板上端中部固定设置有立柱,所述立柱上端通过转轴活动设置有工作台,所述工作台上端一侧固定设置有安装板,所述工作台上端远离安装板的一侧固定设置有支撑管,所述安装板上端中部通过转轴活动设置有绕线盘,所述绕线盘外侧表面缠绕设置有连接绳,所述安装板上端在绕线盘一侧通过安装座固定设置有电动机,所述电动机的输出轴端通过联轴器与绕线盘所在转轴之间传动连接。本发明使用效果好,可以在发生意外如断电时快速自动将连接绳锁死,从而可以防止发生危险,同时在没有断电连接绳下降速度过快时也可以自动将连接绳锁死,以提高装置使用时的安全性。
