Invention content

The purpose of this utility model be solve existing elevator encounter failure midway it is out of service when passenger escape it is inconvenient And the dangerous larger problem of escape, provide escape convenient and safe elevator car.

The purpose of this utility model is achieved by the following technical solution：A kind of elevator car, including car and Car frame, the cage bottom are equipped with escaping exit and escape hatch door, and the car frame both sides are equipped with lifting gear, the lifting dress It sets and is connected with lifter plate.

The car is located in car frame, and the car erects structural support effect.The escape hatch door is normal in elevator It is closed when operation, can in case of emergency open escape hatch door, stranded passenger can pass through the escape under escape hatch door Mouth is transferred on lifter plate.The lifter plate can lift under the driving of lifting gear, and the lifting of the lifter plate can be by multiplying Visitor's control.Stranded passenger can be transferred to the floor bottom surface nearest from failure elevator position by the lifter plate.

Preferably, the car frame is cuboid framework structure, the car frame includes upper beam and bottom girder, the upper beam Column is connected between bottom girder.

Preferably, being equipped with stand-by power supply and control circuit in the car.The control circuit is the lifting gear Power supply is provided.

Preferably, the lifting gear be screw lifting device, the screw lifting device include leading screw, with leading screw phase Feed screw nut even, worm screw and the motor for driving worm screw.

Preferably, the feed screw nut is equipped with worm gear, the worm gear center line is overlapped with feed screw nut center line.

Preferably, connecting feed screw nut on the leading screw, the worm screw engages with the worm gear being located on feed screw nut, institute Motor is stated to connect with the worm screw.

Preferably, the escape hatch door is located on the escaping exit, pass through between escape hatch door and the cage bottom Rotary way connects.The mode of being rotatably connected can be connected by hinge connection or other rotary ways.

Preferably, the escape hatch door is equipped with suppressible handle.

It is stepped on preferably, the lifter plate is equipped with the rising control pedal that can control lifter plate movement and declines control Plate.The trapped person can control rising or falling for lifter plate by trampling to rise control pedal or decline control pedal.

The utility model has the beneficial effects that：It is equipped with escaping exit in cage bottom, being had in car can be in lifting gear The lower lifter plate lifted of driving, enables passenger to be in case of emergency transferred to lifter plate by escaping exit, and control under lifter plate It is down to the floor ground nearest with failure elevator position to leave, improves safety when escape and convenience.

Specific implementation mode

It is further described below by specific implementation mode and in conjunction with attached drawing to the utility model.

Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model includes car frame 2, and the car frame is cuboid framework structure, institute It includes upper beam and bottom girder to state car frame, and column is connected between the upper beam and bottom girder.The column shares four, is respectively provided at The left and right sides has two per side.Car 1 is installed on the car frame.The car 1 is cuboid.1 bottom of the car Equipped with car floor 11, stand-by power supply, control circuit, rising button and declines button are equipped in the car.The car frame 2 On be also equipped with screw lifting device 3, the screw lifting device 3 is mounted among the two root posts per side.The leading screw liter Falling unit 3 includes leading screw 31, feed screw nut 32, worm screw 34 and motor 33, and feed screw nut 32 is connected on the leading screw 31, described Feed screw nut 32 is equipped with worm gear, and the worm gear and feed screw nut are coaxial, and the turbine is connected with the worm screw 34, the worm screw 34 are connected with the motor 33.The leading screw 31 is parallel with column.31 bottom of the leading screw is connected with connecting plate 4, the connection Plate 4 includes rectangle bottom plate, and the rectangle bottom plate is equipped with bolt hole, sets that there are one cylindrical among the rectangle bottom plate Connector.31 bottom end of the leading screw is connected with the connector of the connecting plate 4, and lifting is connected on the bottom plate of the connecting plate 4 Plate 5.The lifter plate 5 is rectangle, and the lifter plate 5 is parallel with car floor 11.The lifter plate is equipped with to rise and control Pedal and decline control pedal.Escaping exit and openable escape hatch door 12 are equipped among the car floor 11.The escape Hatch door 12 is square, and hinge is connected between the escape hatch door 12 and car floor 11.The escape hatch door 12 can be upward Overturning is opened.The escape hatch door 12 is equipped with suppressible handle and handle slot.The handle is hidden in elevator normal operation It ensconces in handle slot.The screw lifting device 3, declines button, rises control pedal and declines control pedal point rising button It is not connected with the control circuit being located in car 1, the control circuit is connected with the stand-by power supply.The rising button, under Drop button rises pedal and declines rising or falling for pedal energy independent control lifter plate 5.

When elevator encounters failure when midway is out of service, stranded passenger can open the escape compartment being located in car floor Door, part are stranded passenger and are entered on lifter plate by escaping exit, and stepping on decline pedal with foot makes lifter plate decline, until declining It extremely with the immediate floor ground in stranded position, decontrols and declines pedal, stranded passenger withdraws from the floor, remaining stranded passenger The rising button being located in car is pressed, hoistable platform is made to rise to initial position, failure electricity is then withdrawn with identical operation Ladder.The lifter plate can once accommodate 3 people, when stranded number is more in elevator, can withdraw failure elevator several times.
