Description
Technical field
The present invention relates to a kind of elevator, especially a kind of elevator that has safety air cushion belongs to elevator guard technology field.
Background technology
In the safety prevention measure of existing elevator, when the speed of car surpassed 1.3 times of command speves, the excision power supply was forced in electric start, makes the band-type brake on the traction main frame, clamping towing machine main shaft; When the speed of car surpasses 1.4 times of command speves, during mechanical actuation, make the safety tongs start on the car, utilize brake shoe clamping rail; When car dropped to pit, the energy disperser on the pit provided the car antagonistic force, take place to reach the accident of avoiding car to smash, but these safety measures only can passively provide the safety of occupant in the car, can't initiatively carry personnel protection in the car.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of elevator that has safety air cushion is provided, it is simple in structure, effectively reduces the menace in the car, and is safe and reliable.
According to technical scheme provided by the invention, a kind of elevator that has safety air cushion comprises hoistway, is positioned at the envelope of hoistway and is positioned at the control housing and the velocity limiter brake plate pull bar on hoistway top; The bottom of described envelope is provided with gas generator, the gas that described gas generator produces feeds and is positioned at the bottom of envelope and the air cushion between the floor, railway carriage or compartment, the input end of described gas generator is connected with an end of removal cable by lower wire, the other end of described removal cable is positioned at control housing, removal cable links to each other with an end of top lead, the other end of top lead is connected with the mouth of electronic sensor, and described electronic sensor is positioned at the bottom of velocity limiter brake plate pull bar.
The downside of described envelope bottom is provided with buffer striking plate, and described buffer striking plate is provided with mechanical sensor, and the mouth of described mechanical sensor links to each other with the input end of gas generator.The bottom of described hoistway is provided with energy disperser, and described energy disperser is corresponding with the position of mechanical sensor on being positioned at buffer striking plate.
Advantage of the present invention: simple in structure, compact and reasonable, when the tenesmus of lift car hypervelocity, gas generator produces gas, makes the air cushion inflation, can effectively protect the safety of personnel in the car.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the present invention is made up of envelope 1, envelope floor 2, gas generator 3, lower wire 4, buffer striking plate 5, energy disperser 6, mechanical sensor 7, air cushion 8, removal cable 9, control housing 10, top lead 11, electronic sensor 12, velocity limiter brake plate pull bar 13 and hoistway 14.
Described envelope 1 is positioned at hoistway 14, and the bottom of envelope 1 is provided with gas generator 3.2 on envelope 1 and envelope floor are laid with air cushion 8, and the gas that gas generator 3 produces feeds in the air cushion 8, and envelope 1 impact to personnel in the envelope in tenesmus is effectively reduced in the space on be used to expand 2 on envelope 1 and envelope floor.Buffer striking plate 5 is positioned at the downside of envelope 1 bottom, and described buffer striking plate 5 is provided with mechanical sensor 7, and the mouth of mechanical sensor 7 links to each other with the input end of gas generator 3.The mouth of described electronic sensor 12 is positioned at control housing 10 removal cables 9 by a top lead 11 and an end and links to each other, and the other end of described removal cable 9 links to each other with the input end of gas generator 3 by lower wire 4.Described electronic sensor 12 is positioned at the bottom of velocity limiter brake plate pull bar 13, when velocity limiter brake plate pull bar 13 is subjected to displacement, the displacement signal that electronic sensor 12 will detect velocity limiter brake plate pull bar 13 feeds back to gas generator 3, makes gas generator 3 produce gas, and air cushion 8 expands.
The bottom of described hoistway 14 is provided with energy disperser 6, and the position of energy disperser 6 is corresponding to the position of the mechanical sensor on the buffer striking plate 57.Described mechanical sensor 7 will detect the signal feedback of energy disperser 6 and give gas generator 3, and gas generator 3 produces gas, and air cushion 8 is expanded.
When tenesmus takes place in envelope 1, if the speed of envelope 1 tenesmus command speed more than 1.4 times the time, can trigger velocity limiter brake plate pull bar 13 and produce action, push down steel rope forward.When electronic sensor 12 detected 13 actions of velocity limiter brake plate pull bar, electronic sensor 12 fed back to gas generator 3 by top lead 11, control housing 10, removal cable 9, lower wire 4 with detection signal; Gas generator 3 produces a large amount of gases, and feeds in the air cushion 8, promotes casing floor 2 behind air cushion 8 inflations upwards, can effectively reduce the impact of envelope 1.
The speed that tenesmus and envelope 1 tenesmus takes place when envelope 1 command speed below 1.4 times the time, envelope 1 can tenesmus, directly clashes into until the energy disperser 6 with hoistway 14 bottoms.Mechanical sensor 7 on the buffer striking plate 5 utilizes lower wire 4 to give gas generator 3 with signal feedback, and the gas that gas generator 3 produces feeds in the air cushion 8, promotes casing floor 2 behind air cushion 8 inflations upwards, can effectively reduce the impact of envelope 1.
