The anti-falling block 3 is arranged on a horizontal anti-falling shaft 6 through a mounting hole, and two ends of the anti-falling shaft are arranged on the lower part of the mounting seat 5. The mounting seat 5 is a shell formed by welding steel plates, the lower part of the inner side of the mounting seat is provided with a circular arc-shaped groove 5a for respectively sleeving two vertical rods of the climbing frame guide rail from two sides, two sides of the upper groove and the lower groove in the mounting seat are respectively and symmetrically provided with a pair of rollers 5b with arc-shaped roller surfaces, the arc-shaped roller surfaces of the rollers are in contact with the vertical rods of the climbing frame guide rail, the vertical rods are fixed, and friction when the climbing frame guide rail goes up and down is reduced.
As shown in fig. 3 and 4, the invention is installed between a building wall 9 and an attached lifting scaffold frame body 10, an installation base 5 of the invention is attached to the building wall through a wall-through screw 8, the installation base is arranged at a position to be installed from top to bottom along a vertical upright post 7 of a climbing frame guide rail, and a toothed plate 1b of a rotating wheel is inserted between crosspieces 7a of the climbing frame guide rail.
