All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

As shown in fig. 1, a safety protection device for high-altitude operation comprises a cat ladder, wherein the cat ladder comprises two groups of mutually parallel support rods, a plurality of connecting rods 2 which are mutually parallel and perpendicular to the support rods are arranged between the two groups of support rods, and the cat ladder can be a cat ladder on an existing tower crane; one side of the supporting rod is provided with a plurality of anti-skid blocks 3, and the supporting rod is also connected with a safety rope 4; the safety rope 4 comprises a hanging ring 401 sleeved on the supporting rod.

The anti-skid block 3 comprises a first surface and a second surface which is positioned above the first surface and is adjacent to the first surface, the first surface is fixedly connected with the supporting rod, and an included angle between the second surface and the first surface is an obtuse angle. The structural design of the anti-skid block 3 needs to ensure that a groove is formed between the anti-skid block and the supporting rod for clamping the safety rope 4 falling above.

As shown in fig. 2, a plurality of grooves are formed in one side of the support rod, on which the anti-skid block 3 is arranged, the first surface of the anti-skid block 3 is located in the grooves, the part of the anti-skid block 3 located in the grooves is movably connected in the grooves through hinges, and when the anti-skid block 3 rotates along the hinges towards the support rod, the part of the anti-skid block 3 can be accommodated in the grooves, and the anti-skid block is mainly used for hanging rings 401 of safety ropes 4 to upwards pass through the anti-skid block 3.
