Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
A kind of horizontal lifting descending lifeline as shown in Figure 1, including hanging ring 1, the lower branch arm of upper branch arm 3, two of roof platform 2, two
4th, plate 5 and screw rod 6 are lifted；The hanging ring 1 is fixedly connected with the upper end of the roof platform 2, two described 3 equal one end of upper branch arm and institute
The lower end for stating roof platform 2 is hinged, and the other end is connect with one end of the lower branch arm 4, the other end and the lifting of the lower branch arm 4
Plate 5 is hinged, and the hole for hoist 51 for hanging jack, each upper branch arm 3 and the lower branch arm are offered on the lifting plate 5
4 junction is provided with pair of nut 7, and 7 hand of spiral of pair of nut of two junctions is on the contrary, the screw rod 6 and two
The pair of nut 7 is threadedly coupled.
Relative to the prior art, using above technical scheme, hanging ring 1 is used for installing whole device, is used for and leads
Lifting equipment connects, and lifting plate lifts cargo by hole for hoist；Upper branch arm 3 forms isosceles three with screw rod 6 respectively with lower branch arm 4
Angular structure, and screw rod 6, by coordinating with pair of nut 7, formation bolt and nut auxiliary structure is adjusted by the precession of screw rod 6,
The angle between the angle between two upper branch arms and two lower branch arms can be adjusted, so play to lift plate promotion and under
Effect drops.
As a preferred mode, upper branch arm 3 is connect with roof platform 2 by bolt and nut, and the length of two upper branch arms 3
Identical, the lower end of every upper branch arm 3 is hinged with a lower branch arm 4.In the present embodiment, as a preferred mode, under
