Abstract

The invention discloses a safe falling protector for a vertical ladder, which comprises a slider seat, a slider, at least one first roller and at least one second roller. The slider seat is provided with a groove, the slider is rotatably connected with the groove, the first rollers are located on the left side of the slider seat, the second rollers are located on the right side of the slider seat, the first rollers are connected with the second rollers via a roller kneading mechanism for adjusting the pitch between each first roller and the corresponding second roller, and the roller kneading mechanism is connected with the slider seat. The pitches between the rollers on the two sides are changed by the roller telescoping mechanism, so that the safe falling protector can be inserted in or taken out conveniently from the front of a guide track of the vertical ladder, and is assembled and disassembled more conveniently.

Description

technical field [0001] The invention relates to a climbing protection device, in particular to a safety fall arrester for a straight ladder. Background technique [0002] When workers climb wind turbines or other similar tall buildings, they use straight ladders to climb upwards, and fall arresters are needed to ensure personnel safety. Such as Figure 1 ~ Figure 3 As shown, the existing fall arrester 1' comprises a slider seat 11', and two groups of rollers 16' are fixed on both sides of the slider seat 11' (see figure 2 ), a groove is provided in the middle part of the slide block seat 11 ', a slide block 12 ' is transferred in the groove, and the upper end of the slide block 12 ' is connected with the upper end of the groove by a rotating shaft 14 '. One side of the slide block 12' directed to the groove is provided with a protrusion 13', and the protrusion 13' is adapted to the socket 101 on the guide rail 100 of the ladder. The surface opposite to the slider seat 11'...
