Abstract
The invention discloses a safety elevator. The safety elevator comprises a shaft way and a lift car, wherein the lift car is arranged in the shaft way; the shaft way is internally provided with a track which is used for guiding the lift car to run and a speed reduction device; the lift car is provided with a connection device which is matched with the speed reduction device and a control device which is used for controlling the connection device to be connected with and disconnected from the speed reduction device. According to the safety elevator disclosed by the invention, when the situation that the speed of the lift car is too fast is detected by the safety elevator, the speed is reduced through hooking a hook to speed reduction sliding blocks, and the speed reduction effect is obvious; when the kinetic energy which is generated during the speed reduction of the lift car is converted into the hydraulic energy of a hydraulic cylinder, the speed is reduced by simultaneously driving a buffer piece and supporting pieces by the hydraulic cylinder, and the safety is further ensured.

Technical scheme of the present invention is: a kind of emergency staircase, comprise hoistway, and be arranged at the car in this hoistway; In described hoistway, be provided with the track for guiding described cage operation, in described hoistway, be provided with speed reduction gearing; On described car, be provided with the connecting device matching with described speed reduction gearing and be connected and throw off the control setup in described speed reduction gearing for controlling described connecting device.
As preferably, described speed reduction gearing is to be fixed on the deceleration slide block on described hoistway by hydraulic actuating cylinder.
As preferably, described connecting device be can hook on described deceleration slide block or throw off in described deceleration slide block and be articulated with the hook on described car outer wall.
As preferably, described control setup comprise for detection of the speed detector of described car speed and control described hook rotate and make this hook can be at hook in described deceleration slide block or throw off the rotating mechanism switching between described deceleration slide block two states.
As preferably, described speed detector is electronic speed probe, and described rotating mechanism is electrical motor.
As preferably, centered by described speed detector, axle is fixedly installed on described car outer wall and outer ring is butted on the fifth wheel on described track, and described rotating mechanism is offset with this fifth wheel outer ring and synchronize with described hook the damping wheel rotating.
As preferably, described car bottom is provided with damper element; Safe chamber is set in described hoistway, in described safe chamber, is provided with and can freely stretches out in the strut member that this safe chamber enters in described hoistway and matches with described damper element.
As preferably, described strut member switches between the two states of described safe chamber by described Driven by Hydraulic Cylinder and in stretching out described safe chamber and retracting.
As preferably, described deceleration slide block is provided with at least two, and along being uniformly distributed from top to bottom in described hoistway, all described deceleration slide blocks are fixing and interlock mutually mutually.
As preferably, described safe chamber and the strut member being arranged in described safe chamber are respectively arranged with at least two, and along being uniformly distributed from top to bottom in described hoistway, all described strut members link mutually.
In sum, the present invention has the following advantages:
1, in the time that elevator detection car speed is too fast, slow down in deceleration slide block by hook hook, deceleration successful;
2,, when the kinetic energy in the time that car slows down is converted to the hydraulic energy of hydraulic actuating cylinder, hydraulic actuating cylinder drives damper element and strut member to slow down simultaneously, further ensures safety.

In figure, 1, hoistway, 2, car, 3, track, 4, deceleration slide block, 5, hydraulic actuating cylinder, 6, hook, 7, fifth wheel, 8, damping wheel, 9, strut member, 10, damper element.
Detailed description of the invention
With embodiment, the invention will be further described below.
Embodiment mono-:
A kind of emergency staircase, as shown in Figure 1, comprises hoistway 1, is arranged at the car 2 in this hoistway 1; In hoistway 1, be provided with the track 3 for guiding car 2 to move, in hoistway 1, be provided with speed reduction gearing; On car 2, be provided with the connecting device matching with speed reduction gearing and be connected and throw off the control setup in speed reduction gearing for control linkage device.
Speed reduction gearing is to be fixed on the several deceleration slide blocks 4 that are uniformly distributed from top to bottom and mutually link on hoistway 1 by hydraulic actuating cylinder 5, connecting device be can hook on deceleration slide block 4 or throw off in deceleration slide block 4 and be articulated with the hook 6 on car 2 outer walls, control setup comprises for detection of the speed detector of car 2 speed and controls the rotating mechanism that hook 6 rotates and this hook 6 can be switched at hook between deceleration slide block 4 or disengagement deceleration slide block 4 two states, centered by speed detector, axle is fixedly installed on car 2 outer walls and outer ring is butted on the fifth wheel 7 on track 3, rotating mechanism be offset with these fifth wheel 7 outer rings and with hook 6 synchronize rotation damping wheel 8.
2 ends of car, are provided with damper element 10; In hoistway 1, be provided with the safe chamber of several well-distributeds from top to bottom, in each safe chamber, be provided with and can freely stretch out in this safe chamber and enter in hoistway 1 and the strut member 9 matching with damper element 10, strut member 9 drives by hydraulic actuating cylinder 5 and switches between the two states of safe chamber in stretching out safe chamber and retracting, and all strut members 9 link mutually.
In the time that car 2 moves, fifth wheel 7 synchronously rotates, fifth wheel 7 drives damping wheel 8 to rotate simultaneously, make to link up with 6 close to deceleration slide block 4, car 2 running velocitys are faster, hook 6 is nearer with deceleration slide block 4 distances, when car 2 running velocitys exceed after safety value, as shown in Figure 2, hook 6 is hung on deceleration slide block 4, and drive deceleration slide block 4 to move downwards, deceleration slide block 4 drives hydraulic actuating cylinder 5 pistons, the kinetic energy of car 2 is converted to the hydraulic energy of hydraulic actuating cylinder 5, in the time that hydraulic actuating cylinder 5 internal pressures change, hydraulic actuating cylinder 5 drives strut member 9 to stretch out in safe chamber, strut member 9 is butted on damper element 10, further car 2 is slowed down.
