Prompt unit includes: display module, alarm bell drive module (it, which is used to warn, has layer door or terraced door not to close) and police Lamp drive module (it, which is used to warn, has layer door or terraced door not to close), display module, alarm bell drive module and warning lamp drive module It is connected to safe rescue master control borad, display module is used to show that long-range rescue assistance is asked under the control of safe rescue master control borad It asks, rescue assistance signal, gate opening and closing situation, layer door opening and closing situation, elevator faults situation, overhauling elevator situation and elevator peace Full loop situation.

In order to design rescue action signal input unit, rescue action signal input unit includes: rescue switch button, is rescued Switch button one end is helped for connecting specific store power module, the rescue switch button other end is for connecting safe rescue master control Plate.There are two the quantity for rescuing switch button, and rescue switch button one is mounted in carriage 6, for trapped person's operation, rescues Helping switch button, another is mounted in emergency crew operations room and (can be computer room), to facilitate emergency crew operations.

The upper end of jam plate and the lower end of jam plate are separately installed with two guide plates 9, and guide plate 9 is connect with jam plate to deviate from backward First electromagnet direction extends, and the first locking bar is able to maintain under the first spring force and is inserted into jam plate.Jam plate 1 and guide plate 9 It can be an integral structure, or split type structure, as long as merging as the shape of such as figure.For design structure letter Single long-range rescue function unit, long-range rescue function unit includes: voice acquisition module, voice playing module, communication module And remote terminal module (can be mobile phone), voice acquisition module and voice playing module with safe rescue master control borad, Voice playing module is used to acquire the voice of trapped person in elevator, and voice module is used to play the voice of long-range salvor, Safe rescue master control borad is connected to remote terminal module by communication module, and remote terminal module comes from safe rescue for obtaining Trapped person's voice in the elevator of master control borad plays trapped person's voice and the voice of the long-range salvor of acquisition in elevator, Remote terminal module is for showing that assistance request, rescue assistance signal, gate opening and closing situation, layer door are opened and closed situation, electricity simultaneously Terraced fault condition, overhauling elevator situation and elevator safety loop situation.

The present embodiment also provides a kind of rescue mode, comprising the following steps:

Step 1: rescue workers and/or passenger press rescue action signal input unit after elevator malfunction, rescue It helps action signal input unit and executes order to the sending rescue movement of safe rescue master control borad；

Step 2: safe rescue master control borad obtains light curtain signal by elevator detection unit, each gate is opened and closed situation signal, Each layer door opening and closing situation signal, elevator faults situation signal, overhauling elevator situation signal and elevator safety loop situation signal；

Step 3: safe rescue master control borad prompts long-range rescue assistance request, rescue assistance signal, sedan-chair by prompt unit Door opening and closing situation, layer door opening and closing situation, elevator faults situation, overhauling elevator situation and elevator safety loop situation；

Step 4: safe rescue master control borad judges whether there is the closing of adjacent layer door, if so, safe rescue master control borad passes through Control elevator executing agency driving unit makes carriage without the direction of the adjacent layer door being not turned off；If it is not, then controlling carriage This direction is not run；(since layer door is opened, it is possible to which someone stretches in layer door, and if there is carriage is passed through, it is existing to will lead to shearing It avoids shearing phenomenon so that there is carriage without the layer door opened as occurring, therefore by this judgement)

Control elevator execution driving unit is ordered to work Step 5: safe rescue master control borad acts to execute according to rescue；

Step 6: carriage is run to level position by elevator executing agency under the control of safe rescue master control borad, simultaneously Safe rescue master control borad controls locking device and carriage is locked in level position；(during this, level position is not reached in carriage Before, safe rescue master control borad just controls the power-off of the first electromagnet, and the second electromagnet is powered, the second locking bar after the second electromagnet is powered The first locking bar is not stopped to move to the position far from the first electromagnet, locking bar stretches out carriage under the first spring force, when first When locking bar is close to jam plate (every floor correspondence is equipped with a jam plate), the first locking bar starts to contact with guide plate 9, in guide plate 9 Slowly the first locking bar is squeezed into carriage under guiding, lockhole is offered on jam plate, slowly the first locking bar slides at jam plate, by It enables to the first locking bar not hinder the lifting of carriage in the effect of guide plate 9, realizes and the first locking bar is expressed in carriage, First locking bar is inserted into lockhole under the first spring force (lockhole diameter is greater than locking bar when the first locking bar is aligned with lockhole Diameter), even if carriage has the power of lifting to be also detached from insufficient for the first locking bar and lockhole at this time, it ensure that carriage is located always In level position, will not after carriage Gravity changer, after operating condition variation due to lead to carriage automatic lifting and safety accident occur)

Step 7: safe rescue master control borad judges carriage leveling by lift car height position signal, output is opened the door Signal, the gate in carriage drive layer door to open, release trapped person.Since the pulley on the door knife and layer door on gate is matched It closes, layer door can be opened while gate is opened, when layer door is closed, each door leaf is respectively connected with a weight, weight in layer door It is suspended in by each door leaf, when layer door is opened, weight is increased；When layer door is closed, two door leafs are made under weight self gravity Close, weight reduces.

Effect:

Existing elevator increases a little hardware device, carries out conveniently, simply, at low cost

The entire rescue operations effective monitoring layer door gate closed state of a, having a power failure when rescue has dedicated emergency power supply, when rescue (the nearlyr layer door of elevator traffic direction or gate) Men Yikai, rescues button inactive, and elevator stops immediately.

The instruction of b leveling accuracy warning lamp stops flashing.Locking device locks carriage, and car weight when rescue is effectively prevent to change Danger caused by caused operating condition variation.

After c leveling (locking device locking carriage) automatic door opening puts people will not be risky.

When personnel pass in and out carriage when d is rescued, carriage is locked, and operating condition changes carriage also without risk.

E rescue time is shorter, and 10 minutes or so, quick and safe.Visualization rescue is safer, more humane.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
