Embodiment Construction
[0018] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0019] Depend on Figure 1 to Figure 11 Given, the present invention includes a wearable safety belt 1, the waist position of the wearable safety belt 1 is provided with an arc-shaped plate 2 with an opening facing the front of the body, and the outer wall of the arc-shaped plate 2 is evenly distributed with multiple groups of ejection components on the circumference, each group The ejection assembly includes a piston cylinder 3 with an opening facing outwards, a first piston 4 is installed in each piston cylinder 3, and a multi-claw hook 5 is connected to the inner end of the first piston 4, and the side wall of the piston cylinder 3 is installed There is an elastic block 6, and a spherical groove 7 is formed on the side wall of the first piston 4. After the first piston 4 is inserted into the piston barrel 3, the head of the elas...

The invention relates to a fall protection device for high-altitude climbing operations, which effectively solves the problem of the low capture success rate of the current ejection-type fall protection devices; the technical solution includes a wearable safety belt, and multiple The ejection device is connected with a hook through a safety rope, and multiple groups of ejection devices can be ejected sequentially in batches. A circular shell is fixed on the wearable safety belt, and an annular first metal sheet is fixed on the inner wall of the circular shell. A lightweight foam board is also installed in the circular shell, and a ring-shaped second metal sheet is mounted on the lower surface of the lightweight foam board. Under the action of its own weight, the first metal sheet contacts the second metal sheet. When it happens, the lightweight foam board is affected by wind resistance so that the first metal sheet and the second metal sheet are separated, thereby triggering the ejection device to eject the hooks sequentially; the present invention can effectively improve the success rate of hook grabbing by designing the hooks ejected in stages.
Description
technical field [0001] The invention relates to the field of protective equipment for high-altitude operations, in particular to a fall protection device for high-altitude climbing operations. Background technique [0002] Working at heights is a common high-risk construction operation. This type of operation inevitably requires climbing high-rise buildings, such as cable towers, high-rise chimneys, etc., and usually requires climbing ladders. Common accidents; at present, the most convenient anti-fall equipment for high-rise ladders is the ejection type. When falling, the acceleration sensor triggers the ejection device to pop up the hook to hook the ladder or the building. This type of equipment does not need to be replaced alternately when climbing. The fixed position of the safety rope does not require brake tracks or brake ropes to be installed beside the ladder, which can effectively increase the climbing speed and has strong applicability. [0003] However, the hook ...
