Abstract

The utility model discloses a rescuing device for a power cut of an elevator without a machine room. In the case of a lift car stops between two adjacent floors when the elevator suddenly powers off, the rescuing workers climb to the top of the lift car, fasten the fixture of the lift car part to the wire rope of the lift car part, a lower hook of a chain hoist or an electric hoist hooks up the fixture of the lift car part, an upper hook of the chain hoist or the electric hoist hooks up the non-lifting location of the elevator and the upper hook serves as a stable supporting point. Rescuing workers pull the manual chain of the chain hoist or the electric hoist and move the chain by the driving of a motor, so as to drive a lifting chain to rise. The lifting chain lifts the lift car by the lower hook, lifts the lift car to a nearest floor and frees the passengers, so that the rescuing work is smoothly accomplished by the fixture of the lift car part and the chain hoist or the electric hoist.

Technical field
The utility model relates to machine-roomless lift power failure deliverance apparatus.
Background technology
For machine-roomless lift, when elevator normally moved, if having a power failure suddenly, lift car probably was parked in the middle of adjacent two stops, and the passenger in the elevator is caught in probably and can't leaves car.Under the circumstances, elevator all can increase urgent electronic this function that has a power failure in standard configuration, specifically, be exactly a UPS emergency source of electrical power to be installed, when elevator has a power failure at well headroom, backup power starts at once, unclamp the towing machine band-type brake, according to cage side and poor to the weight of heavy side, car automatically upwards or run down to nearest stop, open gate and layer door, make the interior passenger of car above water.But, if (1) UPS has fault normally to use; (2) UPS can normally use, but because the unexpected power failure of elevator causes the elevator safety switch motion, and elevator can't move, if run into any in top two kinds of situations, the salvage work of elevator is had reached an impasse.
Summary of the invention
Thereby the purpose of this utility model provides by chain block or electric block and lifts car can discharge the passenger to stop machine-roomless lift power failure deliverance apparatus.
For achieving the above object, the technical solution adopted in the utility model is: machine-roomless lift power failure deliverance apparatus, comprise car, can drive the traction steel-cable of described car lifting, described traction steel-cable comprises and can make the car section steel rope that moves in the same way with described car, described power failure deliverance apparatus also comprise can fixed clamp on described car section steel rope car section folder, suspension hook can hook described car section folder and hook can be hooked in locational chain block or the electric block that described elevator is not done described lifting down.
Preferably, described power failure deliverance apparatus also comprises the counterweight sheave on the counterweight that is arranged on described elevator, be arranged on the car sheave on the sedan-chair frame of described car, one end of described traction steel-cable is fixedly installed in the hoistway of described elevator, the other end is walked around described counterweight sheave downwards, then upwards walk around the traction sheave of described traction machine on elevator again, and then walk around described car sheave downwards, be fixedly installed at last in the described hoistway, described power failure deliverance apparatus also comprises the counterweight section folder that can fixed clamp hooks on described traction steel-cable and the corresponding fixed end of described counterweight and for described hook.
Further preferably, form between described car section folder or described counterweight section folder include grasping part a pair of clamping plate, be opened in the perforation on one of them clamping plate in the described a pair of clamping plate, be opened in tapped bore on the another one clamping plate, can pass described perforation and screw in screw in the described tapped bore, be arranged on and be used for the connecting rod that hooks for described hook or described suspension hook down on the described clamping plate.
Further preferably, the height of described counterweight end face is lower than the height on sedan-chair top on the described car.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: have a power failure suddenly when causing car to be parked in situation between adjacent two stops for elevator takes place, the rescue group climbs on the sedan-chair top of car, car section folder is clamped on the car section steel rope, the following suspension hook of chain block or electric block is hooked on the car section folder, hook is hooked in elevator and does not do on the position of lifting, here hook is made the stable strong point, staff spurs manual chain or electric block moves by the motorized motions chain on the chain block, thereby be with hoisting chain to rise, hoisting chain lifts car by following suspension hook, car is lifted nearest stop, discharge the passenger, then finish salvage work smoothly by car section folder and chain block or electric block.
Description of drawings
Accompanying drawing 1 is looked scheme drawing for the master with elevator of the present utility model;
Accompanying drawing 2 is an A place enlarged drawing in the accompanying drawing 1;
Accompanying drawing 3 is a B place enlarged drawing in the accompanying drawing 1;
Accompanying drawing 4 is the enlarged diagram of overlooking of car section folder in the utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-4, machine-roomless lift power failure deliverance apparatus, comprise car 4, can drive the traction steel-cable 1 of car 4 liftings, traction steel-cable 1 comprises and can make mobile in the same way car section steel rope 3 with car 4, the power failure deliverance apparatus also comprises can the car section folder 10 of fixed clamp on car section steel rope 3, chain block 11, the structure of chain block 11 is referring to Chinese patent literature " explosion-proof chain block ", publication number CN201545654U, open day 2010.08.11, the following suspension hook 13 of chain block 11 is used to hook car section folder 10, hook 12 is used to be hooked in the position that elevator is not done lifting, hook 12 can be made the stable strong point like this, for taking place, elevator has a power failure suddenly when causing car to be parked in situation between adjacent two stops, in Fig. 1, car 4 is parked between adjacent two stops 21 and 22, the rescue group climbs on the sedan-chair top of car 4, car section folder 10 is clamped on the car section steel rope 3, the following suspension hook 13 of chain block 11 is hooked on the car section folder 10, hook 12 is hooked on the position of not doing lifting, the manual chain 14 of pulling chain block 11, be with hoisting chain 15 to rise, hoisting chain 15 lifts car 4 by following suspension hook 13, car 4 is lifted nearest stop, discharge the passenger.Certainly, chain block 11 also can be used electric block instead, and promptly with the electronic staff pulling chain that replaces, all the other structural principles are identical with the structural principle of chain block 11, can lift car by hoisting chain equally like this.
The elevator of traction ratio 2:1 has been shown among Fig. 1, the power failure deliverance apparatus also comprises the counterweight sheave 8 on the counterweight 7 that is arranged on elevator, be arranged on the car sheave 6 on the sedan-chair frame 5 of car 4, one end 2 of traction steel-cable 1 is fixedly installed in the hoistway of elevator, the other end is walked around counterweight sheave 8 downwards, then upwards walk around the traction sheave of traction machine on elevator 20 again, and then walk around car sheave 6 downwards, be fixedly installed in the hoistway at last, the power failure deliverance apparatus also comprises can the counterweight section folder 9 of fixed clamp on traction steel-cable and the corresponding fixed end 2 of counterweight, hook 12 can hook counterweight section folder 9, certainly in a further embodiment, hook can also be hooked in the fixed position in the elevator hoistways, as long as can allow hook as the stable strong point.
