Background technique
Most important in escape device is exactly drop device, a kind of when using escaping rope, for reducing decrease speed
Tool, it can also be used to which protection operator is (sometimes for protection in moving (outward bound, mountain-climbing, the limit, open air etc.), rescuing
Trapped person) protector, also cry " decline protector "；It and " lifting device " are by increasing to rope (wirerope, rail relatively
Road) frictional force reinforce buffering effect, to achieve the purpose that " descending at slow speed "；Common drop device mainly has stop decline
Protector, 8 word rings, Multifunctional pulley etc..Certainly, we can also be wound on a common D type safety door hook with rope
An easy drop device is made twice, drop device is divided into two classes in use: one, being the i.e. operator at operator
Drop device is connected on half (complete) body safety belt by member by safety door hook, and then controlling decrease speed by grip (can also be by restricting
The personnel of rope lower ends are controlled by tensing rope by its tension)；It two, is at trapped person.Rescue personnel will decline
After device is connect with trapped person, the decrease speed of trapped person is controlled by controlling the decrease speed of drop device, until safety
It reaches ground (safety place)；Drop device is generally used for the relief of high-order trapped person in rescue disposition.And currently on the market
The more of drop device be exactly 8 word rings, and 8 word rings need to control the angle of rope in time when being declined, and are not easy to
People control decrease speed when by extraneous factor in time.
