Definitions

  • the invention relates to a suspension descent system, in particular to a suspension descent system which is manually controlled by gravity of a human body. Background technique
  • cleaning the exterior wall ⁇ usually uses a seat-type single-use spreader. When using it, first select a fixed place on the top of the building, and use all the corners of the rope, ribs and laps. To prevent the abrasion of the sling; then put a special knot on the sling in the lowering of the seat sling. Because there is such a special knot, at work, the hanging plate does not slide down, and the person controls the rope and can operate freely. To put it simply, when you lift the rope and the hanging plate, it will slide down a little, how much slippery, how fast and how fast, until the end of the work. This tool can also be used for high-altitude exterior wall painting projects.
  • the suspension descent system is mainly composed of a working rope, a descender, a connector, and a seat plate device.
  • Dropper A device that is mounted on a working rope and powered by the operator's own weight and controlled by hand.
  • the types of descenders include: rod, multi-plate, splayed and shackle type, among which shackle type lowers Commonly known as U-shaped crab buckle.
  • Connector A ring-like part with a normally closed valve that connects the internal parts of the system together.
  • Seat plate device A device for carrying workers, consisting of a sling, a lining and a seat plate.
  • the seat type single spreader is a special knot in the lowering device. Due to the friction generated by the special knot and the gravity of the free end of the rope (the end of the rope drooping to the ground), the friction of the special knot and the gravity of the free end rope are called the forces that hinder the lowering of the human body. When the sum of all the resistances including the above two resistances is greater than the human gravity, the human body will be suspended in the air. When it is at a high position, because the gravity of the free end rope is very large, when the human body needs to descend, the free end rope must be lifted up, so that the special knot is not tightened. At this time, the human body is lowered when the rope is lifted, and the rope is lifted.

Abstract

L'invention porte sur un système de descente à suspension, lequel système comprend un câble de travail (1), un descendeur (2), une plaque de liaison (3.1) et un dispositif de support (4). Le câble de travail est attaché avec un nœud spécial sur le descendeur. De plus, sur le descendeur est disposée une plaque latérale (2.3.1) comportant un élément de traction à déflexion (6.1, 6.2). En un lieu élevé, la gravité de l'extrémité libre du câble est très grande. A ce moment, l'élément de traction à déflexion peut être actionné par un corps humain pour faire subir une déflexion au descendeur. Alors, le câble à l'arrière du nœud spécial est dans un état pendant librement, et le frottement du nœud spécial est réduit. Par conséquent, le corps humain peut descendre automatiquement par sa seule gravité, ou la force de descente du corps par la traction du câble vers le haut sera plus petite.
