Abstract
The invention discloses a novel escape device having the functions of two products, namely, an escape descent control device (GB21976.2-2012) and an emergency escape device (GB21976.5-2012). The device is mainly utilized for safe descending in emergency escape and lifesaving outside a tall building. According to the escape device, one end of a steel wire rope is hung on a fixed device inside a room, the other end of the steel wire rope is vertical to the outdoor ground, and an escape person descends along with the escape device; when feeling frightened or encountering obstacles, the escape person can automatically brake to control the descending speed, and the function conforms to the function requirement of the emergency escape device; and the escape device has an automatic brake function, when the escape person does not automatically brake, the escape device can automatically limit the speed to descend at a constant speed, and the function conforms to the function requirement of the escape descent control device.
Description
Technical field
The present invention is a kind of double brake type Lifesaving device, be mainly used in high building because of burst fire or
Other emergencies, help escape personnel's escape device from the high building escape unharmed scene of the accident.
Background technology
Escaping descent control device (GB21976.2-2012) used in reality typically uses list at present
Rope sheave structure, according to internal structure difference be divided into again gear train (such as Fig. 1) and planetary gearsets (as
Fig. 2) two kinds of structures；
Lifesaving device (GB21976.5-2012) used in reality typically uses snail at present
Worm and gear formula braking (such as Fig. 3) or lever braking (such as Fig. 4) two kinds of structures.
The escaping descent control device of single rope sheave structure is suspended in the fixing device in room, and descending lifeline is solid
Fixed motionless, descending lifeline can not decline with escape personnel simultaneously, the one rise and one drop successively of the two ends of rope,
Being similar to fixed block principle, survivor can only decline with the speed of relative constancy
(0.16 meter～1.5 meters per second of " GB21976.2-2012 " national regulations decrease speed), escape
Person's uncontrollable descending lifeline speed, if just in case there is mechanical breakdown or the process of decline in descending lifeline
Middle survivor meets with barrier, and survivor cannot tackle, and can only leave it to chance, now escape
Person is uneasy just as bungee jumping, and that time that escape personnel jumps out outside window just gives life
Descending lifeline.Escaping descent control device brake material in the market is usually metal material or rubber
Material manufactures, and metal is less than normal with metal friction coefficient, meets water (as rainy day escapes) and does not almost have
There is frictional force.When metal meets water with rubber friction, frictional force will be had a greatly reduced quality.The funeral of frictional force
Losing or weaken and all will directly jeopardize the life security of survivor, safety reliability is not enough.
Worm-gear type or lever-type Lifesaving device (GB21976.5-2012), due to system
Dynamic pressure block directly bears against on rope, pause and transition in rhythm or melody or the phenomenon of card rope easily occurs, sternly during decline
During weight, rope is even broken and splits by briquetting, the most directly jeopardizes the life of survivor, potential danger
Danger is the biggest, and this kind of structure can not support that distance escape, so " building fire is escaped device of taking refuge
Material-outfit guide GB21976.1-2012 " regulation Lifesaving device height is 15 meters.
Present invention
The present invention is a kind of double brake type Lifesaving device, and survivor's decrease speed is by equipment
Braking mode own and survivor actively braking constitutes double braking.Rope one end of escape apparatus is hung on
On room inner fixing device, the other end falls in outdoor surfaces, and escape apparatus is internal uses duplex type wheel construction,
This structure can make escape apparatus together decline with survivor, during declining such as barrier or
Other emergency, escape personnel is slowed or shut off lower reduction of speed by manipulation actively brake unit
Degree.If survivor the most actively brakes, escape apparatus is internally installed self-braking device, it is ensured that escape
Survivor's speed limit is at the uniform velocity slowly landed ground along steel wire rope with the speed of 0.16～1.5 meter per second
(parachutist land speed be 5 meters per second), the braking brake pad of self-braking device by
Engineering plastics coated metal manufactures, and reaches 0.6 with the coefficient of friction of steel, not only has higher
Coefficient of friction, and when meeting water, it is maintained to enough coefficient of frictions.The grooving of rope sheave
In have the muscle of some projections to add frictional force and the tautness of rope and rope sheave, promote further
General safety effectiveness；
The present invention is a kind of double brake type Lifesaving device, is made up of 4 parts: housing portion,
Braking mode part, actively brake portion and steel wire rope part, described housing portion is by upper shell
Form with lower casing, form an entirety by the connection of bolt with fixed disk, it is possible to protection is escaped
The parts of raw device interior tissue；Described Braking mode part is by braking pallet, braking brake pad
Deng composition, the gear on rope sheave A by with the engaging of gear train, rotation function is passed to system
Moving plate, 4 braking brake pads are evenly distributed in the draw-in groove of braking pallet, and braking pallet is being justified
In all rotary courses, braking brake pad relies on from reforming centrifugal rotation, and braking brake pad is work
Engineering plastics coated metal material, inwall and bottom surface with lower casing form friction resistance the most successively
Power, even if survivor does not carry out actively braking, remains able to guarantee that survivor's speed limit is the safest
Decline, with automatically control decrease speed meet GB " GB21976.5-2012 " require (per second
0.16 meter～1.5 meters).Described active brake portion is by rope sheave A, rope sheave B, caliper, system
The compositions such as dynamic connecting rod, brake lever, brake rope.There is regulation decrease speed or stop declining
Function, rope sheave A and rope sheave B by lifting rope motion be able to circumference rotate.Caliper
Being arranged at the middle cylindrical of rope sheave A and rope sheave B, caliper application position is at two rope sheaves
At cylindrical, not with rope contact, will not interfere with or break rope, therefore escape altitude can reach
To more than 300 meters.The torque ratio of brake lever is 1: 3；When escape personnel strains brake rope
Time, the active force having 3 times is passed to caliper, by brake connecting rod and the company of brake lever
Connect, the gap of caliper and rope sheave can be regulated, regulate frictional resistance, to reduce or to stop
The only purpose of the rotation of rope sheave, it is thus possible to reduce or stop the decrease speed of escape personnel.
Lifesaving device is a kind of device placed and do not use, therefore material choosing
By aluminium alloy, rustless steel and engineering plastics, rustness avoidance and long service life, it can be ensured that escape personnel
The most reliably use, the escape unharmed high building scene of the accident.
The recyclable storage after escape uses of this Lifesaving device device, standby next time, escape makes
With.
