Abstract

The invention relates to a suspension descending system. In order to overcome the problems that when existing seat board type single hanger is used, people need great effort to lift the rope during descending, even the rope cannot be lifted, and great trouble is brought to construction and operation. The invention provides the suspension descending system, wherein a deflection drawing piece is arranged to change the trend behind the special knot so as to change the frictional force of the special knot. When people is in high altitude, the gravity of the rope at the free end is large, and the human body operates the deflection drawing piece to deflect a descender, so that the rope after the special knot is in a free suspension state and the frictional force of the special knot is lessened. Therefore, the human body can descend automatically by own gravity or lifts the rope upward with little effort, and certain problems in construction and operation are solved.

Description

A kind of suspention decline system

Technical field

The present invention relates to a kind of suspention decline system, relate in particular to a kind of with human body self weight be gravity, suspention decline system by hand control.

Background technology

In daily, usually use the single suspender of using of seat board formula during cleaning outer wall, during use, at first select a fixedly place of fastening rope at the roof place, with all ropes take the angle, take rib, at the bottom of the place of taking eaves uses rubber pad, in case the friction wear lifting rope; To beat what a special knot in the drop device on the present formula boatswain chair of lifting rope again.Because so special knot is arranged, so at work, boatswain chair can be toward not gliding, and the people controls rope, can free operant.Briefly, glide a bit, what are carried what are slided, carry and how soon how soon sliding, up to end-of-job when up rope, boatswain chair are just past.External rendering engineering in high-altitude also can be used this instrument.Because when using suspender, the user of service also will carry out constructing operation together except operation rope descends, owing to be aloft work, therefore work has certain danger.The single suspender high-altitude application of use seat board formula person must be the male citizen over 18 one full year of life, and through physical examination and safety method training, can operation through passing the examination, the workman is pre-job must not to drink, and has uncomfortable symptom such as flu just must suspend aloft work.The single advantage with suspender of seat board formula is simple in structure, and is easy to operate, if safety measure is done thoughtfully, it is very high to use safety.
