Abstract

The invention provides an elevator emergency rescue device which comprises a traction steel wire rope, an elevator car, a traction machine and a counterweight device and further comprises a guiding wheel located on one side opposite to the traction machine, a steel wire rope winding and releasing device for tightening or releasing the traction steel wire rope to enable an elevator to reach to a nearby flat floor, and a rope clamping device for clamping and fixing the traction steel wire rope, wherein the traction steel wire rope is guided by the guiding wheel and then extends downward to be connected with the steel wire rope winding and releasing device. During emergency rescue, the steel wire rope winding and releasing device is operated, and meanwhile the rope clamping device releases the traction steel wire rope, so that the elevator can ascends or descends to reach the nearby flat floor, and trapped persons can be rescued. The elevator emergency rescue device is simple in structure and convenient to operate and saves the time and the labor, and the rescue purpose can be achieved safely, conveniently and quickly.

Description

A kind of emergency rescue device for elevator
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, to the requirement of its safety, is generally very high.But in some cases, elevator power-off or other fault still can occur elevator, for how rescuing fast and effectively trapped personnel, be also a very important problem.During traditional elevator emergent rescue, generally all need the band-type brake of towing machine to open, while having machine room, can carry out jiggering by handwheel, make car arrive flat bed nearby, when during machine room, if car and counterweight weight are more or less the same, rescue difficulty is larger, can realize downward flat bed by increase cage side weight and put people, often consuming time, effort, and danger greatly.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of car that in case of emergency can make safely, easily and quickly and 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 the relative side of described towing machine track adjusting wheel, for tightening up or loosening described traction steel-cable, make described car arrive the steel rope draw off gear of flat bed nearby and for the rope gripper of the described traction steel-cable that is fixedly clamped, 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, described steel rope draw off gear comprise reel for furling described traction steel-cable, drive big gear wheel that described reel rotates, with the miniature gears of described big gear wheel engagement, drive the reducing motor of described miniature gears.
Further, on described reel, reel and be 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, increased track adjusting wheel, steel rope draw off gear and rope gripper, in the time of under the non-rescue state of elevator, rope gripper is all the time in closure state, thereby improved 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 to open the band-type brake of 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.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
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 is in elevator hoistways top and be positioned at the relative side of described towing machine 9.Steel rope draw off gear comprises reel 3 for furling described traction steel-cable 2, drive big gear wheel 4 that described reel rotates, with the miniature gears 5 of described big gear wheel 4 engagements, drive the reducing motor 6 of described miniature gears 5.Traction steel-cable 2 one end are fixed on hoistway top, the other end, successively through pulley and the backward downward-extension of track adjusting wheel 7 of the pulley of counterweight 10, towing machine 9, car 8 bottoms and be fixedly connected with reel 3, is reeled on reel 3 and 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.
Reel 3 forward or reverse by steel rope draw off gear, to tighten up or to loosen traction steel-cable 2, are put people thereby make car 8 arrive flat bed nearby, 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 having the elevator of machine room, described steel rope draw off gear also can be arranged on the machine room of elevator.
Should adopt a flowing mode when driving reducing motor 6 work of reel 3, and should link with described rope gripper 1, that is: when described reducing motor 6 crawls are worked, 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 is not worked, the closed traction steel-cable 2 that clamps of described rope gripper 1.
Emergency rescue device for elevator of the present invention when implementing rescue without the band brake apparatus of opening described towing machine 9, only need described reducing motor 6 crawl operations, described rope gripper 1 is opened in interlock simultaneously, make described car 8 upstream or downstream carry out flat bed and put people, can reach safely, easily and quickly rescue object.
