The adjusting cross bar 2 is provided with a rotating handle 25, a screw rod 251, a round clamping plate 252 and a fixed plate 26. The rotating handle 25 drives the screw rod 251 to rotate, and the screw rod 251 drives the fixed plate 26 to move up and down through the round clamping plate 252, which can fix the roof beam during hoisting. The end of the adjusting cross bar 2 is connected with a locking rod 3, and the locking rod 3 is clamped with the fixed hook rod 1, which can prevent the roof beam from falling off during hoisting.
[0025] Furthermore, the fixed hook rod 1 includes a pull rod 11 and a bearing cross bar 12. A cable sleeve 13 is arranged outside the pull rod 11, and the cable sleeve 13 is located at the upper end of the pull rod 11. The bearing cross bar 12 is fixedly connected to the inner side of the pull rod 11, and the bearing cross bar 12 is located at the bottom end of the pull rod 11. The cable sleeve 13 is used to connect the cable, which is convenient for lifting this safety protection tool for roof beam hoisting.
[0026] Furthermore, a plurality of uniformly distributed positioning jacks 111 are provided on the pull rod 11. At the other end of the bearing cross bar 12, a fork-shaped part 121 is provided. At the bottom of the fork-shaped part 121, a clamping block 122 is provided. The fork-shaped part 121 facilitates the positioning of the lock top rod 3.
[0027] Specifically disclosed, the adjusting cross bar 2 includes a horizontal straight bar 21 and a sliding sleeve 22. The sliding sleeve 22 is fixedly arranged at the left end of the horizontal straight bar 21. The sliding sleeve 22 is sleeved outside the pull rod 11.
