[0027] like Figure 1-2As shown, the I-beam safety belt suspension device provided by the utility model includes a fixed rod 1, one end of the fixed rod 1 is provided with a fixed support rod 2 through a support rod fixing sleeve 11, the other end of the fixed rod 1 is provided with a sliding support rod 3 through a support rod sliding sleeve 12, and the middle of the fixed rod 1 is provided with a U-shaped shackle 4 through a shackle sliding sleeve 13; the upper ends of the fixed support rod 2 and the sliding support rod 3 are both provided with rollers 5 through roller bolts 51, and the bottoms of the two rollers 5 are both provided on the lower flange plate of the I-beam.

[0028] like Figure 3 As shown, when the utility model is used, firstly, the roller 5 of the fixed support rod 2 is placed on the lower flange plate on one side of the I-beam 7. Then, according to the width of the lower wing of the I-beam, the distance between the fixed support rod 2 and the sliding support rod 3 is adjusted so that the roller 5 of the sliding support rod 3 is placed on the lower flange plate on the other side of the I-beam 7. Finally, the safety belt is hung on the U-shaped shackle 4. Under the action of the shackle sliding sleeve 13, the U-shaped shackle can be adjusted left and right along the fixed rod 1; under the action of the shackle sliding sleeve 13, the safety belt can move along the lower flange plate of the I-beam; under the action of the roller 5, the safety belt can follow the movement according to the change of the working position. After use, the fixed rod 1 is removed from the I-beam 7 together with the roller 5, and can be removed together with the safety belt. It is convenient to install and disassemble, improves work efficiency, and can ensure the safety of high-altitude workers.

[0029] The support rod sliding sleeve 12 is provided with a tightening bolt 14; the support rod fixing sleeve 11 is provided with a fixing bolt 15. By tightening the tightening bolt 14, the support rod sliding sleeve 12 can be fixed on the fixing rod 1; by loosening the tightening bolt 14, the position of the sliding support rod 3 can be adjusted according to the width of the lower wing of the I-beam, so that the roller 5 of the sliding support rod 3 can be placed on the lower flange plate on the other side of the I-beam 7, which is convenient for adjustment and improves work efficiency.
