Description
Technical field
The utility model is a kind of two brake type Lifesaving device, is mainly used in high building because of burst fire or other emergencies, helps escape personnel from the escape device of the high building escape unharmed scene of the accident.
Background technology
The escaping descent control device (GB21976.2-2012) used in current reality generally adopts single rope sheave structure, is divided into again gear train (as Fig. 1) and planetary gearsets (as Fig. 2) two kinds of structures according to internal structure difference;
The Lifesaving device (GB21976.5-2012) used in current reality generally adopts Worm-gear type braking (as Fig. 3) or lever braking (as Fig. 4) two kinds of structures.
The escaping descent control device of single rope sheave structure is suspended in the fixture in room, descending lifeline maintains static, descending lifeline can not decline with escape personnel simultaneously, two ends one rise and one drop successively of rope, be 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), the uncontrollable descending lifeline speed of survivor, if descending lifeline meets with barrier just in case there is survivor in mechanical breakdown or decline process, survivor cannot tackle, can only leave it to chance, now survivor is uneasy just as bungee jumping, that time that escape personnel jumps out outside window has just given descending lifeline life.Escaping descent control device brake material is in the market generally metal material or elastomeric material manufacture, metal and metal friction coefficient less than normal, meet water (as rainy day escape) almost there is no frictional force.When metal and rubber friction meet water, frictional force will be had a greatly reduced quality.The forfeiture of frictional force or weaken and all will directly jeopardize the life security of survivor, security reliability is not enough.
Worm-gear type or lever-type Lifesaving device (GB21976.5-2012), because braking briquetting is directly pressed on rope, the phenomenon of pause and transition in rhythm or melody or card rope is easily there is in decline process, time serious, rope even breaks and splits by briquetting, so just directly jeopardize the life of survivor, potential danger is very large, and this kind of structure can not support long distance escape, so " building fire escape take refuge equipment-outfit guide GB21976.1-2012 " regulation Lifesaving device height is 15 meters.
Summary of the invention
The utility model is a kind of two brake type Lifesaving device, and survivor's decrease speed is initiatively braked by the Braking mode of equipment own and survivor and formed two braking.Rope one end of escape apparatus is hung on room inner fixing device, the other end falls in outdoor surfaces, escape apparatus inside adopts duplex type wheel construction, this structure can make escape apparatus and survivor together decline, as barrier or other emergency in decline process, escape personnel is slowed down by manipulation active brake apparatus or is stopped decrease speed.If survivor does not initiatively brake, escape apparatus inside is provided with self-braking device, guarantee that survivor's speed limit at the uniform velocity slowly to be landed ground (parachutist's speed of landing is 5 meters per second) along steel wire rope with the speed of 0.16 ~ 1.5 meter per second, the braking brake pad of self-braking device is manufactured by engineering plastics coated metal, 0.6 is reached with the coefficient of friction of steel, not only there is higher coefficient of friction, and when meeting water, still can keep enough coefficient of frictions.There is the muscle of some projections to add frictional force and the tautness of rope and rope sheave in the grooving of rope sheave, improve general safety validity further.
The utility model is a kind of two brake type Lifesaving device, be made up of four parts: housing parts, Braking mode part, initiatively brake portion and steel wire rope part, described housing parts is made up of upper shell and lower casing, be connected to form an entirety by bolt and fixed disk, the parts of escape apparatus interior tissue can be protected, described Braking mode part is by braking pallet, the compositions such as braking brake pad, gear on rope sheave A by with the engaging of gear train, rotation function is passed to brake disc, 4 braking brake pads are evenly distributed in the draw-in groove of braking pallet, braking pallet is in circumference rotary course, braking brake pad relies on deadweight to form centrifugal rotation, braking brake pad is engineering plastics coated metal material, respectively form frictional resistance with the inwall of lower casing and bottom surface successively, even if survivor does not carry out active braking, still can guarantee that survivor's speed limit declines at the uniform velocity safely, GB " GB21976.5-2012 " requirement (0.16 meter ~ 1.5 meters per second) is met automatically to control decrease speed.Described active brake portion is made up of rope sheave A, rope sheave B, caliper, brake connecting rod, brake lever, brake rope etc.Have the function regulating decrease speed or stop declining, rope sheave A and rope sheave B is able to circumference by the motion being elevated rope and rotates.Caliper is arranged on the middle cylindrical place of rope sheave A and rope sheave B, and caliper application position is at the cylindrical place of two rope sheaves, and not with rope contact, can not interfere or break rope, therefore escape altitude can reach more than 300 meters.The torque ratio of brake lever is 1: 3; When escape personnel strains brake rope, to the force transmission of 3 times be had to caliper, by the connection of brake connecting rod and brake lever, the gap with rope sheave can be clamped by adjustable brake, regulate frictional resistance, to reach the object of the rotation reducing or stop rope sheave, thus can reduce or stop the decrease speed of escape personnel.
