Description

A kind of work high above the ground safety device
Technical field
The utility model relates to aerial work equipment field, particularly a kind of work high above the ground safety device.
Background technology
Work high above the ground and to climb all be dangerous high activity, especially in the construction operation, falling in the high-altitude is to cause the industrial injury main causes of death, annual high-altitude falling accident is up to 40000 to 75000, and is death by accident more than 80%.Work high above the ground always allows the people sweat with anxiety or fear, and the tragedy that relevant work high above the ground is fallen down from the building and lost one's life is reported in media frequently.The quick economic environment that increases, very high to the building trade demand for development, especially work high above the ground is the quite high industry of degree of danger, onerous toil intensity and all accident factors that may occur at any time all directly threaten workmen's personal safety.
In order to strengthen work high above the ground personnel's safety, usually can allow the operating personnel use the work high above the ground safety belt at present, work high above the ground safety belt commonly used mainly comprises: the operation rope, and for carrying and protection operator's boundary belt, boundary belt lifting device and drop device.The operation rope is connected with boundary belt, and boundary belt lifting device and drop device all are located on the described operation rope, and a wherein end of boundary belt lifting device and drop device all is connected with boundary belt.
When the operation rope is pulled, the human body built on stilts, described boundary belt and operator are suspended in together in the air.When needs were regulated operator's flying height, the operator operated described boundary belt lifting device or drop device moves to the target location.
The problem that exists is: use existing work high above the ground safety device, the operation rope is subjected to pulling force straight down, bearing capacity is relatively poor, may rupture at any time when the operation rope is excessive because of holding capacity, and the safety guarantee in the skyborne work progress of operator is lower.
The utility model content
A kind of work high above the ground safety device that the utility model provides, the safety guarantee in the time of can improving operator's operation aloft.
The technical solution of the utility model is achieved in that a kind of work high above the ground safety device, comprises the operation rope, boundary belt, and the boundary belt lifting device, drop device also comprises:
Safety line and device hoist cable;
Described safety line and the sagging setting side by side of described operation rope;
