Description

A kind of double-guarantee two-person high building lifesaving slow falling apparatus

Technical field

A kind of double-guarantee two-person high building lifesaving slow falling apparatus of the present invention belongs on the high-rise and falls people's device.

Background technology

At present, the slow descending device of disclosed band brake mechanism mostly still adopts traditional friction member damping principle, as ZL99239958.0, and ZL02251039 (reciprocating descent control device) etc.No matter these devices are that its weak point is all can not adjust automatically exactly, makes the people with at the uniform velocity decline as safe as a house by operation speed governing or automatic control velocity.And used rope separates with reducing gear, the same housing of not packing into, and its structure is disperseed, and volume is big, stores and carry inconvenience.

Because directly adopt frictional force to carry out speed governing, during use, starting power is bigger, for centrifugal member, a decline Acceleration Height need be arranged, this stage decrease speed instability.In addition, its load capacity is less, can only carry a people at every turn, and for a tame 2-3 mouth people, under critical situation (as the big fire earthquake), who carries afterwards earlier carries, and in the mutual pass of safety in the heart, brings great psychological fear to the people.

The escape device for high-rise buildings that a kind of novel employing inertia damping principle is carried out automatic speed regulation, as ZL93218292.5, solved automatic accurate speed governing, problem that at the uniform velocity descends, and cable wire safely and reducing gear are with packing a housing into, its compact conformation, volume is little, be easy to carry, load capacity is bigger during use, once can carry 1-2 people; And starting power is minimum, and decline instantaneous can in time enter the state that at the uniform velocity descends.Its weak point is that the change-speed gearing of speed adjusting gear is the transmission of 2-3 level, and gear is more, causes cavity volume bigger, in addition, in order to reduce volume around the rope frame, cable wire adopt enough safety than thin tightwire, for carrying 2 people, then need to improve the safety coefficient of cable wire.

There is automatic control velocity exactly in above-mentioned slow descending device; Can not make human body with at the uniform velocity decline as safe as a house, and rope and reducing gear can not be with packing a housing into; Can only carry a people deficiency during use at every turn.

Summary of the invention

The purpose of this invention is to provide a kind of double-guarantee two-person high building lifesaving slow falling apparatus, when high-rise was met danger, carrying person passed through at the uniform velocity descending lifeline of of the present invention pair of rope, realizes safe life-saving from high building.The invention provides the double-guarantee two-person high building lifesaving slow falling apparatus that a kind of employing inertia damping principle of simplifying gear drive is carried out automatic speed regulation, automatic control velocity exactly, make the people with at the uniform velocity decline as safe as a house, and cable wire and the same housing of packing into of reducing gear, its volume is little, is convenient to store and carry.During use, once can carry 2 people, guarantee that with the dual fail-safe scheme safety at the uniform velocity descends.

The present invention solves the dual fail-safe technical scheme that its technical problem adopts: make up with single speed adjusting gear with around the rope frame, form one and independently divide descending lifeline, independently divide descending lifeline with two again, be installed in parallel the right and left respectively, form a dual fail-safe descending lifeline in same shell combination.Its concrete measure is: the gear graduation train is designed to one-level gear graduation train, forms simple inertia damping speed adjusting gear, i.e. escapement speed adjusting gear with escapement lever and escape wheel.With this speed adjusting gear, the left and right symmetrically same cylindrical housings of packing into; The corresponding same housing of packing into also have symmetrical two around rope frame combination, this two combination same main shaft of packing into independently of each other, and rotating around same main shaft.Two carrying persons' body weight is acted on respectively on two cable wires, release by cable wire makes two around rope frame combination becoming separately torque, pass through the one-level speed change of driving gear and driven pinion again separately, make the escape wheel high speed rotating, and the drive escapement lever is done the high-frequency inertia damped oscillation, this oscillatory feedback, with the constant high speed rotating of control escapement crop rotation, transmission through driven pinion and driving gear, driving gear is slowed down into constant slowly running, send two respectively to around the combination of rope frame, it is at the uniform velocity descended on request.Two carrying persons link to each other, when certain when speed adjusting gear or cable wire delivery system break down on one side (out of control, fall), two carrying persons are born by speed adjusting gear, the cable wire delivery system of another side, guarantee at the uniform velocity to descend with the safety of corresponding two body weight for humans.

The invention has the beneficial effects as follows that automatic control velocity exactly makes doublely with the at the uniform velocity decline of safety, and volume is little, is convenient to storage and carries; Simple in structure, good manufacturability during use, once can be carried two people, with the dual fail-safe scheme, has guaranteed safety, has at the uniform velocity descended.Be no more than at load capacity under the situation of rated weight, can carry three people.Rated weight as the carrying of this product is 240 kilograms.
