Abstract
The invention provides a kind of emergency rescue device for elevator, comprise traction steel-cable, car, towing machine, counterweight, also comprise: be positioned at described towing machine relative to side track adjusting wheel, make described car arrive the steel rope draw off gear of flat bed nearby and the rope gripper for the described traction steel-cable that is fixedly clamped for tightening up or loosening described traction steel-cable, described traction steel-cable is guided backward downward-extension by described track adjusting wheel and is connected with described steel rope draw off gear.When emergency relief, by operation steel rope draw off gear, and decontrol traction steel-cable with seasonal rope gripper, make car upstream or downstream arrive nearby flat bed to rescue trapped personnel, structure of the present invention is simple, easy to operate, time saving and energy saving, can reach rescue object safely, easily and quickly.
Description
Technical field
The present invention relates to a kind of emergency rescue device for elevator.
Background technology
Elevator is the instrument of a kind of very important manned or thing in people's daily life, is generally very high to the requirement of its safety.But in some cases, elevator power-off or other fault still can occur elevator, be also a very important problem for how rescuing trapped personnel fast and effectively.During traditional elevator emergent rescue, generally all need the band-type brake of towing machine to open, have during machine room and can carry out jiggering by handwheel, car is made to arrive flat bed nearby, if when during machine room, car and load weight are more or less the same, rescue difficulty is larger, realizes downward flat bed put people by increase cage side weight, often consuming time, effort, and dangerous large.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of in case of emergency can make safely, easily and quickly car arrive nearby flat bed to rescue the emergency rescue device for elevator of trapped personnel.
For achieving the above object, the invention provides a kind of emergency rescue device for elevator, comprise traction steel-cable, car, towing machine, counterweight, it is characterized in that, also comprise: be positioned at described towing machine relative to side track adjusting wheel, make described car arrive the steel rope draw off gear of flat bed nearby and the rope gripper for the described traction steel-cable that is fixedly clamped for tightening up or loosening described traction steel-cable, described traction steel-cable is guided backward downward-extension by described track adjusting wheel and is connected with described steel rope draw off gear.
Preferably, described rope gripper is mechanical type wire holder or electromagnetic type wire holder.
Preferably, the described steel rope draw off gear reducing motor that comprising reel for furling described traction steel-cable, driving the big gear wheel of described spool turns, the miniature gears engaged with described big gear wheel, driving described miniature gears.
Further, on described reel, winding is reserved with the traction steel-cable of certain length.
Preferably, described steel rope draw off gear is arranged on elevator pit.
Preferably, described steel rope draw off gear is arranged on the stop of the arbitrary flat bed of elevator.
Preferably, described steel rope draw off gear is arranged on the machine room of elevator.
Compared to prior art, the present invention has the following advantages: on the basis of existing elevator components, adds track adjusting wheel, steel rope draw off gear and rope gripper, time under the non-rescue state of elevator, rope gripper is in closure state all the time, thus improves the safety of elevator operation; When emergency relief, only need to start steel rope draw off gear, and open rope gripper simultaneously, make car upstream or downstream to flat bed nearby to rescue trapped personnel; In emergency relief process, do not need the band-type brake opening towing machine completely, this feature seems particularly important when machine-roomless lift is rescued.
Accompanying drawing explanation
Fig. 1 is the structural representation of emergency rescue device for elevator of the present invention.
In accompanying drawing: 1-rope gripper, 2-traction steel-cable, 3-reel, 4-big gear wheel, 5-miniature gears, 6-reducing motor, 7-track adjusting wheel, 8-car, 9-towing machine, 10-counterweight.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Refer to Fig. 1, it illustrates a kind of emergency rescue device for elevator, comprises traction steel-cable 2, car 8, towing machine 9, counterweight 10, track adjusting wheel 7, steel rope draw off gear and rope gripper 1.Wherein, track adjusting wheel 7 to be in above elevator hoistways and to be positioned at the relative side of described towing machine 9.The reducing motor 6 that steel rope draw off gear comprising reel 3 for furling described traction steel-cable 2, driving the big gear wheel 4 of described spool turns, the miniature gears 5 engaged with described big gear wheel 4, driving described miniature gears 5.Traction steel-cable 2 one end is fixed on above hoistway, the other end is fixedly connected with reel 3 to downward-extension through after the pulley bottom the pulley of counterweight 10, towing machine 9, car 8 and track adjusting wheel 7 successively, and on reel 3, winding is reserved with the traction steel-cable 2 of certain length.Described rope gripper 1 is positioned at the below of track adjusting wheel 7 and is located on the extension path of traction steel-cable 2, for the traction steel-cable 2 that is fixedly clamped.
By reel 3 forward or reverse of steel rope draw off gear to tighten up or to loosen traction steel-cable 2, thus make car 8 arrive flat bed nearby to put people, reach safety, Quick rescue.In the elevator of machine room, described steel rope draw off gear can be arranged on the stop of elevator pit or the arbitrary flat bed of elevator, with handled easily.In the elevator having machine room, described steel rope draw off gear also can be arranged on the machine room of elevator.
A flowing mode should be adopted when working in order to drive the reducing motor 6 of reel 3, and should link with described rope gripper 1, that is: during described reducing motor 6 crawl work, described rope gripper 1 is opened and is decontroled traction steel-cable 2, and reducing motor 6 can drive reel 3 forward or reverse to tighten up or to loosen traction steel-cable 2; When described reducing motor 6 does not work, the closed clamping traction steel-cable 2 of described rope gripper 1.
Emergency rescue device for elevator of the present invention implement rescue time without the need to opening the band brake apparatus of described towing machine 9, only need described reducing motor 6 crawl operation, described rope gripper 1 is opened in interlock simultaneously, make described car 8 upstream or downstream carry out flat bed and put people, rescue object can be reached safely, easily and quickly.
