Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure, as the terms used are used to describe particular embodiments only, and are not intended to limit the exemplary embodiments based on the disclosure.
Fig. 1 and 2 show that the utility model relates to a ladder anti-falling device, which comprises a rectangular frame 1 and a plurality of one-way stoppers 2 uniformly distributed in the frame 1. The frame 1 is placed vertically and its long side is in the vertical direction. The one-way stopper 2 includes a left guide 21, a right guide 22, and a trip prevention catch 23. The left end of the left guide 21 is fixed on the left long side of the frame 1, and the right end of the right guide 22 is fixed on the right long side of the frame 1 opposite to the left guide 21; the left guide 21 and the right guide 22 are both long and extend from the fixed end to the middle of the frame 1 and incline upwards.
A gap is reserved between the two free ends of the left guide piece 21 and the right guide piece 22 so that a safety rope can pass through the gap; reinforcing rib plates 24 are arranged at the bottoms of the left guide part 21 and the right guide part 22, and top surfaces 27 of the reinforcing rib plates 24 are planes extending obliquely upwards and are fixed on the bottom edge 25 of the left guide part 21 or the right guide part 22; the sides 26 of the stiffener plates 24 are fixed to the long sides of the frame 1.
The anti-tripping device 23 is a spring, and one end of the anti-tripping device 23 is arranged above the left guide piece 21; the other end of the trip preventing mechanism 23 is a free end, and is overlapped on the right guide member 22 in a spring releasing state, and the free end of the trip preventing mechanism 23 is separated from the right guide member 22 in a spring compressing state.
The outside on the long limit of cat ladder anti-falling device right side (also can be the left side) is equipped with fixing device 3, fixing device 3 is the fixed hangers of several evenly distributed on long limit.
As shown in fig. 3, the top surfaces of the left guide 21 and the right guide 22 may be arc-shaped extending from the fixed end to the middle of the frame 1 and inclining upward, and correspondingly, the top surface 27 of the reinforcing rib plate 24 provided at the bottom of the left guide 21 and the right guide 22 is an arc surface extending obliquely upward and fixed to the bottom edge 25 of the left guide 21 or the right guide 22; the sides 26 of the stiffener plates 24 are fixed to the long sides of the frame 1.
