Abstract
The invention discloses a speed reduction falling preventing elevator. The elevator comprises an elevator shaft and a car platform sill located in the elevator shaft and is characterized in that an embedded guide rail is arranged on the wall of the elevator shaft, the car platform sill is installed on the embedded guide rail in a matched mode through a guide shoe, and a flexible side wing matched with the cross section of the elevator shaft in shape and a rolling mechanism are installed at the bottom of the car platform sill. When the car platform sill operates normally, the rolling mechanism controls the flexible side wing to roll so that the car platform sill can operate normally, and when the car platform sill falls, the rolling mechanism controls the flexible side wing to be unfolded to form motive seal with the wall of the elevator shaft so that the car platform sill can slow down under the action of bottom air pressure. The speed reduction falling preventing elevator has the advantages that when the car platform sill falls, the flexible side wing is unfolded to form motive seal with the wall of the elevator shaft, so that the car platform sill becomes a structure similar to a piston to extrude air below, and high pressure is generated to offset gravity of the car platform sill to reduce speed.
Description
Technical field
The invention belongs to elevator technology field, be specifically related to a kind of anti-fall elevator that slows down.
Background technology
The appearance of skyscraper substantially increases land utilization ratio, and brings, for people, chance of preferably going sightseeing, and promotes city image glamour simultaneously, becomes the impression window of urban development.As one of part requisite in skyscraper, elevator plays an important role.According to incompletely statistics, by the end of 2015, the whole nation is total to be in military service more than 1,000,000 elevators, it can be seen that, elevator has become one of requisite instrument in daily life.The quantity of elevator not only grows with each passing day, and the research of elevator is the most day by day goed deep into by people.In long-term research and using, it has been found that the safety problem of elevator becomes the focus making us most paying attention to, and all big enterprises also put into substantial contribution and manpower researches and develops more advanced safety device.But in some occasion, owing to the potential safety hazard of incorrect use and elevator existence itself easily causes the generation of used during elevator falling accident, thus cause casualties and economic loss.The safety device preventing used during elevator falling at present is the safety tongs that limiter of speed is handled, and when elevator drops certain speed, limiter of speed handling safety is clamped down on and stopped car.But handling safety clamps when speed is higher, car, passenger, guide rail etc. easily causing bigger harm, and the structure composition of this protector is complex, fault rate is high, safeguard inconvenience etc..Therefore based on this problem, it is necessary to research and develop a kind of safe and reliable novel elevator.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of anti-fall elevator that slows down, it is possible to utilize elevator to utilize well internal gas pressure to realize slowing down with coordinating of car.
For solving prior art problem, the invention discloses a kind of anti-fall elevator that slows down, including elevator and the car that is positioned in elevator, the borehole wall of elevator is provided with embedded guide rail, car coordinates installation by leading boots with embedded guide rail；The bottom of car is provided with the flexible edge wing that shape matches, and rolling-up mechanism with elevator cross section；When car is properly functioning, rolling-up mechanism controls flexible edge wing rolling and realizes the properly functioning of car, and when car drop, the rolling-up mechanism control flexible edge span is opened and realized movable sealing with hoistway wall and make car slow down under the gas pressure of bottom.
Preferably, rolling-up mechanism includes hoist engine, the rolling steel cable being wrapped on hoist engine cylinder, and collects the sleeve pipe of rolling steel cable；The end of rolling steel cable is divided into four strands and is connected with the four points of connection on the flexible edge wing respectively thus realizes the control to the flexible edge wing.
Preferably, car is made up of light material, and elevator inwall is lubricious ceramic face.
Preferably, be provided with bottom elevator only permitted that air enters mustn't the check valve gone out of air.
Preferably, the cross section of elevator is circular or square, and the cross section of car is also circular or square.
Preferably, the flexible edge wing is made up of rubber.
The invention have the benefit that
1. during car tenesmus, the flexible edge span is opened and hoistway wall forms movable sealing, so that car becomes the gas of the structure extruding bottom of similar piston thus produces powerful pressure and offset with car gravity and play deceleration purpose.
2. the flexible edge wing can free rolling and expansion under the control of rolling-up mechanism, thus ensure to rapidly enter duty and realize deceleration purpose during tenesmus.
3. the check valve in elevator can stop gas leak thus make cage bottom can produce sufficiently large pressure and make it slow down.
4. car is made up of light material, greatly reduces the weight of car, and hoistway wall is smooth ceramic plane, it is possible to closely cooperating with the flexible edge wing forms effective movable sealing structure.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As shown in Figures 1 to 4, a kind of anti-fall elevator that slows down, including elevator 1 and the car 3 that is positioned in elevator 1.The cross section of elevator 1 is circular or square, and its borehole wall is provided with embedded guide rail 2, and the cross section of car 3 is also circular or square, and coordinates installation by leading boots with embedded guide rail 2.The top of car 3 is connected with to pouring weight 5 by dragged wire-rope 6, is arranged on pouring weight 5 in the passage outside elevator 1.The bottom of car 3 is provided with the flexible edge wing 4 that shape matches with elevator 1 cross section and is made up of rubber, and rolling-up mechanism.
Rolling-up mechanism includes hoist engine, the rolling steel cable 8 being wrapped on hoist engine cylinder, and collects the sleeve pipe 7 of rolling steel cable 8；The end of rolling steel cable 8 is divided into four strands and is connected with the four points of connection on the flexible edge wing 4 respectively thus realizes the control to the flexible edge wing 4.
Car 3 is made up of light material, and elevator 1 inwall is lubricious ceramic face.Be provided with bottom elevator 1 only permitted that air enters mustn't the check valve gone out of air.
The operation principle of the present invention and process
When car 3 is properly functioning, the traction motor rotating speed that electric control system detects is normal, and thus without sending control instruction, hoist engine keeps rolling state to make the flexible edge wing 4 rolling realize the properly functioning of car 3.When traction motor generation hypervelocity makes car 3 drop, electric control system detects overspeed signal and is simultaneously emitted by control instruction and makes hoist engine release rolling steel cable 8 be launched by the flexible edge wing 4, and now the flexible edge wing 4 and elevator 1 wall are in close contact and realize movable sealing thus make car 3 slow down under the gas pressure of bottom.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
