Abstract
The invention discloses a rescuing device for a machine-room-less elevator. A power device can rescue people trapped in an elevator cage and needing to be rescued when an elevator is in power failure or in failure, a main body wheel of a speed limiter or a tensioning wheel of the speed limiter are driven to rotate, so that a steel wire rope of the speed limiter is driven to move, the elevator cage is driven by the steel wire rope of the speed limiter to move, so that the elevator cage levels automatically, so that the weights of the two ends of a traction machine are the basically same, the people trapped in the elevator can be rescued conveniently, the operations that people throw sandbags to the top of the elevator or people in a bottom pit need to pull the steel wire rope of the speed limiter or a compensation chain and the like can be avoided, and the rescuing device has the advantages that the efficiency is high, the operation is simple and convenient, and the potential safety hazards in rescuing can be reduced.
Description
Technical field
the present invention relates to machine-roomless lift deliverance apparatus.
Background technology
elevator is the instrument of a kind of very important manned or thing in people's daily life, generally very high to the requirement of its safety, but in some cases, still can there is power-off or other fault in elevator, cause personnel to be trapped in car, how rescuing quickly and efficiently trapped personnel is a very important problem.Tradition machine-roomless lift rescue mode is: first the spanner that declutches of the towing machine of machine-roomless lift is opened, if when now the weight at towing machine two ends (be cage side with to heavy side) differs larger, now car can be automatically moved to level position, after this open a layer gate, thereby trapped personnel is rescued; If differing, the weight at towing machine two ends not very large, be that car and counterweight reach state of equilibrium, now must make car move down into level position by the way that increases car weight, the method that increases car weight is: to the throwing sandbag of sedan-chair top, the weight of car is increased, or people stand in pit, pulls speed limiter wire rope or compensated chain (when elevator design has compensated chain, can operate compensated chain), thus make lift car leveling.Existing machine-roomless lift rescue efficiency is low, operation inconvenience.
Summary of the invention
thereby the object of this invention is to provide the machine-roomless lift deliverance apparatus that speed limiter wire rope is moved allow car automatic leveling by engine installation.
for achieving the above object, the technical solution used in the present invention is: a kind of machine-roomless lift deliverance apparatus, comprise car, velocity limiter, described velocity limiter comprises velocity limiter main body wheel, governor tension pulley, upwards walk around described velocity limiter main body wheel and then walk around the speed limiter wire rope of described governor tension pulley downwards, described speed limiter wire rope is connected with described car, described machine-roomless lift deliverance apparatus also comprises and can in the time that described elevator power-off or et out of order need to be rescued car trapped personnel, drive described velocity limiter main body wheel or described governor tension pulley to rotate the engine installation with mobile described speed limiter wire rope, the propulsion source of this engine installation additionally exists with respect to the general supply of described machine-roomless lift operation use.
preferably, the first gear on the output shaft that described engine installation comprises the motor that can turn round in the time that described elevator power-off or et out of order need to be rescued car trapped personnel, be contained in described motor, and second gear that be fixedly installed coaxial with described governor tension pulley, the setting that is meshed with described the second gear of described the first gear.
preferably, the propulsion source of described engine installation adopts the lithium cell that can be charged by the general supply of described machine-roomless lift operation use.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: engine installation can drive velocity limiter main body wheel or governor tension pulley to rotate in the time that elevator power-off or et out of order need to be rescued car trapped personnel, thereby drive speed limiter wire rope to move, move with car by speed limiter wire rope, make car automatic leveling, differ while not being very large in the weight at towing machine two ends like this, can rescue trapped personnel in car easily, avoid in pit, drawing the operation such as speed limiter wire rope or compensated chain to the throwing sandbag of sedan-chair top or people, it is high that this deliverance apparatus has efficiency, easy and simple to handle, reduce the feature of rescue potential safety hazard.
Brief description of the drawings
accompanying drawing 1 is schematic diagram of the present invention;
the schematic diagram that accompanying drawing 2 is medium power device of the present invention.
Detailed description of the invention
further set forth structure of the present invention below in conjunction with accompanying drawing.
shown in Fig. 1-2, a kind of machine-roomless lift deliverance apparatus, comprise car 1, velocity limiter 12, engine installation 10, velocity limiter 12 comprises velocity limiter main body wheel 2, governor tension pulley 3, upwards walk around velocity limiter main body wheel 2 and then walk around the speed limiter wire rope 11 of governor tension pulley 3 downwards, speed limiter wire rope 11 is connected with car 1, engine installation 10 can drive velocity limiter main body wheel 2 or governor tension pulley 3 to rotate in the time that elevator power-off or et out of order need to be rescued car trapped personnel, thereby drive speed limiter wire rope 11 to move, move with car 1 by speed limiter wire rope 11, make car 1 automatic leveling, differ while not being very large in the weight at towing machine two ends like this, can rescue the interior trapped personnel of car 1 easily, without drawing the operation such as speed limiter wire rope or compensated chain to the throwing sandbag of sedan-chair top or people in pit, it is high that this deliverance apparatus has efficiency, easy and simple to handle, reduce the feature of rescue potential safety hazard.This engine installation 10 is owing to working under elevator powering-off state, therefore the propulsion source of engine installation 10 additionally exists with respect to the general supply of machine-roomless lift operation use.
in Fig. 2, engine installation 10 comprises the reducing motor that can turn round in the time that elevator power-off or et out of order need to be rescued car trapped personnel, the first gear 6 and the second gear 5 that arrange are meshed, in reducing motor, motor 9 by coupler 8 by transmission of power to drop-gear box 7, the first gear 6 is contained on the output shaft of drop-gear box 7 in reducing motor, the second gear 5 is coaxial and be fixedly installed with governor tension pulley 3, when motor 9 turns round like this, by engaging of the first gear 6 and the second gear 5, rotate with governor tension pulley 3, drive speed limiter wire rope 11 to move and make car 1 flat bed.The propulsion source of engine installation 10, be that the propulsion source that drive motor 9 turns round can adopt lithium cell, the general supply that this lithium cell can be moved use by machine-roomless lift is charged, when elevator normally moves like this, by general supply to lithium cell charging, in the time that needs are rescued, lithium cell electric discharge, drive motor 9 turns round.
to sum up, this machine-roomless lift deliverance apparatus is in the time of work, when the weight at towing machine two ends differs while not being very large, now can be by electrical control, make engine installation action, drive speed limiter wire rope to move, finally allow car automatic leveling, avoid in pit, drawing the operation such as speed limiter wire rope or compensated chain to the throwing sandbag of sedan-chair top or people, there is the features such as efficiency is high, easy and simple to handle, reduction rescue potential safety hazard.
