Description
Technical field
The present invention relates to a kind of elevator power failure emergency rescue device.
Background technology
As domestic real estate market is fast-developing again, the demand of elevator is also being continuously increased, elevator closes people's failure
Also more and more, usual elevator, which closes people, has computer room to declutch in computer room the mode of jiggering, and machine room match somebody with somebody electric brake releasing mode, logical
Lift car and counterweight unbalanced moments are crossed to realize that car slipping is rescued, when carriage and counterweight both sides weight are exactly like or differ
When little, when unbalanced moments can not overcome traction sheave frictional force, just only rescue can not be realized by declutching merely at this time.
Currently the majority Elevator Factory breaks static balance by increasing weight in car top or sedan-chair, and which is in contiguous floors spacing mistake
Height, when elevator is parked in centre position, people can not go up car top or weighting material can not just realize rescue in sedan-chair.Another
It is provided with the mode that counterweight is hooked on compensated chain and breaks static balance, the counterweight that this method breaks static balance needs at least 200KG
Frictional force can just be overcome, and hooked the compensated chain after counterweight also because impaired broken ring needs replacing.

2 lower section is provided with regulating device, and the regulating device is movably connected with steel wire rope 7.
The regulating device includes adjusting bracket 11, and big drive link 12, the big biography are provided with the adjusting bracket 11
Big rotating wheel 13 is rotatablely equipped with lever 12, the big rotating wheel 13 is connected with 14 one end of rescue steel wire rope, the rescue steel
Fixed block 15 is installed on 14 other end of cord；Drive big rotating wheel 13 to rotate big turn is also equipped with the adjusting bracket 11
Driving wheel driving mechanism.Regulating device is set to be detachable, and adjusting bracket 11 is reserved expansion bolt by cheating bottom and is detachably secured to
Cheat bottom.
The big rotation actuation includes small drive link 16, small transmission wheel 17, and peace is rotated in the adjusting bracket 11
Equipped with small drive link 16, small transmission wheel 17 is installed on the small drive link 16, the small transmission wheel 17 is nibbled with big rotating wheel 13
Close and be connected.
Manual rocker 18 is installed on the small drive link 16 in the outside of adjusting bracket 11.
Self-locking mechanism is installed, the self-locking mechanism includes self-locking interlocking bar 21, locking chuck in the adjusting bracket 11
22, self-locking interlocking bar 21 is rotatablely equipped with the adjusting bracket 11, and locking chuck 22 is installed in the self-locking interlocking bar 21,
The retaining groove 23 that the gear teeth screens with small transmission wheel 17 is connected is offered on the locking chuck 22.
The first limiting groove 24 is offered on the locking chuck 22 of 23 side of retaining groove, the retaining groove 23 is another
The second limiting groove 25 is offered on the locking chuck 22 of side, is pacified in 24 or second limiting groove 25 of the first limiting groove
Equipped with voussoir 26.
It is described that weights stack 1 forms pouring weight by more than 1 piece.
A kind of elevator power failure emergency rescue device described in the present embodiment when in use, is divided into carriage 2 rescue and sedan-chair upwards
Rescue downwards in railway carriage or compartment 2.
When carriage 2 is rescued upwards, since 7 one end of steel wire rope is fixed on to 1 lower end of weights stack, and 7 other end of steel wire rope
2 lower end of carriage is fixed on, is then fixed on rescue steel wire rope 14 on the steel wire rope 7 to 1 lower end of weights stack by fixed block 15.
Then manual rocker 18 is shaken, the manually rotation of rocking bar 18 drives 17 turns of small transmission wheel being installed on manual rocker 18
It is dynamic, it is connected since small transmission wheel 17 is engaged with big rotating wheel 13, small transmission wheel 17 rotates the rotation for driving big rotating wheel 13.
Keep off the tightening of rescue steel wire rope 14 for driving one end to be installed on big rotating wheel 13 when big rotating wheel 13 rotates and be wound in big drive link
On 12.Since rescue steel wire rope 14 is subject to the lower pulling force of the big rotation of rotating wheel 13, so as to installed in the steel below weights stack 1
Cord 7 forms lower pulling force, so as to will decline to weights stack 1, weights stack 1 is declined, and drives 2 uplink of carriage.In this rescue operations
In, voussoir 26 is installed in the first limiting groove 24, so that retaining groove 23 is separated with the gear teeth of small transmission wheel 17, so that not
Influence the rotation of small transmission wheel 17.When carriage 2 rises to layer nearby, interior extraction voussoir 26, makes out of first limiting groove 24
Voussoir 26 rotates, and when retaining groove 23 contradicts the gear teeth of small transmission wheel 17, voussoir is embedded in the second limiting groove 25
26, so as to limit the rotation of voussoir 26, while prevent small transmission wheel 17 from inverting, improve security.
When carriage 2 is rescued downwards, since 7 one end of steel wire rope is fixed on to 1 lower end of weights stack, and 7 other end of steel wire rope
2 lower end of carriage is fixed on, is then fixed on rescue steel wire rope 14 on the steel wire rope 7 of 2 lower end of carriage by fixed block 15.Then
Manual rocker 18 is shaken, the manually rotation of rocking bar 18 drives the small transmission wheel 17 being installed on manual rocker 18 to rotate, by
Engage and be connected with big rotating wheel 13 in small transmission wheel 17, therefore small transmission wheel 17 rotates the rotation for driving big rotating wheel 13.Gear is big
Rotating wheel 13 drives one end to be installed on big rotating wheel 13 tightening of rescue steel wire rope 14 when rotating is wound on big drive link 12.
Since rescue steel wire rope 14 is subject to the lower pulling force of the big rotation of rotating wheel 13, so as to installed in 7 shape of steel wire rope below carriage 2
Into lower pulling force, so that carriage 2 be declined, carriage 2 is declined, is driven to 1 uplink of weights stack.Similarly, when carriage 2 drops to nearby
During layer, interior extraction voussoir 26, makes voussoir 26 rotate out of first limiting groove 24, when retaining groove 23 contradicts small transmission wheel
During 17 gear teeth, voussoir 26 is embedded in the second limiting groove 25, so as to limit the rotation of voussoir 26, while prevents small transmission wheel
17 reversions, improve security.
A kind of elevator power failure emergency rescue device of the present embodiment, its is simple in structure, easy to use, in case of emergency fast
Fast safety makes carriage reach the rescue purpose of layer realization nearby.
