The invention relates to a hoisting device, and discloses an underground large-span large-space ultrahigh column-free steel structure pipe truss suspension device which comprises a hoisting frame and a fastening device, the fastening device is installed at one end of a rope, the other end of the rope is connected with the hoisting frame, and the underground large-span large-space ultrahigh column-free steel structure pipe truss suspension device is characterized in that the fastening device comprises a fastening clamp, a driven clamp and a movable rod. After the movable rod is pressed through the pawl, the one-way arc-shaped tooth is limited, the movable rod and the fastening clamp are locked, then the pipe truss is fastened by the fastening clamp and the driven clamp, after the pipe truss is hoisted and installed, the pawl is rotated by hand, the one-way arc-shaped tooth is restored to the free end, the movable rod and the spring are pushed reversely to reset, and the pipe truss is fixed. The fastening clamp is separated from the driven clamp, so that the pipe truss is prevented from sliding in the lifting process and falling off, and meanwhile, the pipe truss lifting device is easy to operate and convenient for workers to use.

    本发明涉及起吊装置,公开了一种地下大跨度大空间超高无柱钢结构管桁架悬吊装置,包括起吊架和紧固装置,所述紧固装置安装在绳索的一端,所述绳索的另一端与起吊架连接,其特征在于,所述紧固装置包括紧固夹、被动夹和活动杆。本发明通过棘爪使活动杆在被按压后,将单向弧形齿进行限位,使活动杆与紧固夹被锁定,进而使管桁架被紧固夹与被动夹紧固,当管桁架被吊起安装完成后,用手转动棘爪,使单向弧形齿重新恢复为自由端,反向推动活动杆,弹簧复位,使紧固夹与被动夹远离,以防止管桁架在被吊起的过程中不会滑动,以防止管桁架掉落,同时操作简单方便工作人员使用。
