Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

Referring to Fig. 1, Fig. 2 and Fig. 3, a safety belt suspension device for aerial work includes a clamping structure for fastening on a cement rod (cement member) and a suspension structure for hanging the safety belt. The clamping structure has Two arc-shaped panels 1 arranged up and down, each panel 1 is provided with a ratchet fixing belt for fastening the panel to the cement rod, and each panel 1 is provided with a connecting rod 3 on the side away from the ratchet fixing belt (the front of the panel in the attached drawing Side), the end of the connecting rod 3 (the front end in the drawing) is provided with a fastener 4 for clamping the supporting steel pipe; the suspension structure has a vertically arranged supporting pipe 5, and the top of the supporting pipe 5 is provided with a safety belt hanging ring 6 , the support tube 5 is arranged at two fasteners 4 and clamped by the fasteners 4 .

In the clamping structure, there are at least two fasteners, and three, four, or more can be set according to actual needs. Set accordingly.

The safety belt hanging ring 6 has an annular body 61, a rod-shaped part 62 is arranged on one side of the ring-shaped body 61, and the safety belt hanging ring 6 is detachably arranged on the top of the support tube 5 through the rod-shaped part 62, or the safety belt The hanging ring 6 is welded on the top of the support pipe 5 through a rod-shaped member 62 .

There are many ways to fasten the panel with the ratchet fixing belt, and only two ways are listed in the examples:

The first solution: as shown in Figure 1, one end of the panel 1 is provided with a ring-shaped fastening body 11, and the other end is provided with a fixing belt 12, and one end of the belt-shaped structure 2 of the ratchet fixing belt is fastened on the ring-shaped fastening body 11, and the ratchet wheel is fixed. The ratchet structure of the belt (the ratchet structure at the end of the ratchet fixing belt) is connected with the end of the fixing belt 12 to clamp the panel 2 on the cement pole;

The second scheme: as shown in Figure 2, the ratchet fixing belt has a ratchet structure 13 and a belt-shaped structure 2, and one end of the panel is provided with a ring-shaped fastening body 11, and one end of the belt-like structure 2 of the ratchet fixing belt is fastened On the fastening body, the ratchet structure 13 of the ratchet fixing band is arranged at the other end of the panel, and the other end of the belt-shaped structure of the ratchet fixing band is connected with the ratchet structure 13 arranged at the other end of the panel to clamp the panel on a concrete pole.
