Abstract
The invention specially discloses an elevator falling buffering device. The elevator falling buffering device comprises an elevator car and a buffering mechanism, wherein the buffering mechanism comprises a buffering plate, stretching springs, friction discs and air bags, which are arranged between the elevator car and the wall of an elevator well; the lower end of the buffering plate is movably hinged to the lower end of the elevator car, and the stretching springs are fixedly arranged between the upper end of the car and the buffering plate; the air bags are fixedly arranged between the buffering plate and the car; the air bags comprise a gravity acceleration sensor, a control module and air bag modules; the gravity acceleration sensor, the control module and the air bag modules are electrically connected. The elevator falling buffering device can be independently arranged with other safety guard devices and can enable the falling speed of the car out of control to be reduced, so that the greatest safety can be provided for passengers in the car.
Description
Technical field
The present invention relates to elevators field, be specifically related to a kind of elevator tenesmus shock absorber.
Background technology
Elevator is vertical transport instrument, and car is the pith of passenger loading, and therefore the safety of car is most important.In running process of elevator, car is along guide rail up-and-down movement, and passenger stand at the bottom of sedan-chair and moves with car.When lift car runs downwards, due to the disconnected rope of hoist ropes, car overload, safety tongs velocity limiter be failure to actuate, skidding between traction sheave and hoist ropes, misfunctioning of brake, brakeless moment and the reason such as limit switch is inoperative, can cause that car is out of control to fall to pit.At this moment the energy disperser be contained in below car in pit can alleviate the impact between car and pit, but the buffering effect only provided by energy disperser still can not ensure car and passenger injury-free.Because making energy disperser directly and car effect, when car contacts with energy disperser, the falling speed of car reaches maxim, and now car and energy disperser direct effect still can damage the member in car.For this reason, be badly in need of exploitation a kind of can independent of other safety guard, can slow down car out of control time the shock absorber of falling speed.
Summary of the invention
The object of the invention is to solve deficiency of the prior art, provide a kind of can independent of other safety guard, can slow down car out of control time falling speed elevator tenesmus shock absorber.
For achieving the above object, base case of the present invention is: elevator tenesmus shock absorber, comprise car and the buffer gear of elevator, buffer gear comprises the dash plate between car and hoistway wall, extension spring, friction lining and safety air bag, the lower end of dash plate and the lower end of car are movably hinged, extension spring is fixedly installed between the upper end of car and dash plate, safety air bag is fixedly installed between dash plate and car, safety air bag comprises Gravity accelerometer, control module, and air bag module, air bag module comprises gas generator and air bag, Gravity accelerometer, control module and air bag module electrical connection.
Principle of work and the advantage of this programme are: when elevator normally runs, and are held dash plate to prevent friction lining from contacting with hoistway wall by extension spring.When car is out of control fall downwards rapidly in elevator time, Gravity accelerometer detects that the falling speed of car exceedes early warning value, then control gas generator by control module and open air bag, the air bag opened overcomes the resistance of extension spring and friction lining is pressed to hoistway wall simultaneously, due to the mutual rubbing effect between friction lining and hoistway wall, the falling speed of car will slow down or even car stops tenesmus.
The falling speed that the buffer gear actv. that car is arranged slow down car even can also allow car be stuck in elevator; the safety air bag adopted is also independent of other safety guard; so this device can independent of other safety guard and can slow down car out of control time falling speed, and provide maximum safety for the passenger in car.
Preferred version one: based on the preferred version of scheme, comprise two buffer gears, two buffer gears are symmetricly set on the left and right sides of car respectively.Two change mechanism into and act on the friction force that can improve further between car and elevator simultaneously, for the passenger safety in car provides larger guarantee.
Preferred version two: the preferably preferred version of, dash plate is also provided with withstand the top of hoistway wall.The top of setting can reduce the speed of car tenesmus or even allow car stop tenesmus, so arrange the top larger safety having ensured passenger in car.
Preferred version three: the preferably preferred version of two, dash plate is also provided with the barb catching on hoistway wall.The barb arranged can reduce the speed of car tenesmus or even allow car stop tenesmus, so arrange the larger safety having ensured passenger in car of barb.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of elevator of the present invention tenesmus shock absorber embodiment.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: hoistway wall 1, car 2, extension spring 3, friction lining 4, top 5, air bag module 6, stay bearing plate 7, barb 8, Gravity accelerometer 9.
Embodiment is substantially as shown in Figure 1:
Elevator tenesmus shock absorber, comprise the buffer gear that the sidewall of car 2 is arranged, buffer gear comprises dash plate, extension spring 3, friction lining 4 and safety air bag between car 2 and hoistway wall 1, the lower end of dash plate and the lower end of car 2 are movably hinged, be fixedly installed extension spring 3 between the upper end of car 2 and dash plate, friction lining 4 is between hoistway wall 1 and dash plate and be fixedly installed on dash plate.Safety air bag is fixedly installed between dash plate and car 2.In the present embodiment, the air bag module 6 that safety air bag comprises Gravity accelerometer 9, control module and forms together with gas generator does with air bag etc., Gravity accelerometer 9, control module and air bag module 6 is electrically connected.Gravity accelerometer 9 is arranged on the car 2 of elevator, Gravity accelerometer 9 and gas generator Access Control simultaneously module.As shown in Figure 1, at ordinary times, by extension spring 3, dash plate is held to prevent friction lining 4 from contacting with hoistway wall 1.When car 2 is out of control fall downwards rapidly in elevator time, Gravity accelerometer 9 detects that the falling speed of car 2 exceedes early warning value, then control gas generator by control module and open air bag, the air bag opened overcomes the resistance of extension spring 3 and friction lining 4 is pressed to hoistway wall 1 simultaneously, due to the mutual rubbing effect between friction lining 4 and hoistway wall 1, the falling speed of car 2 will slow down or even car 2 stops tenesmus.
As shown in Figure 1, in the present embodiment, the sidewall of car 2 is provided with two buffer gears, two buffer gears are symmetricly set on the left and right sides of car 2.Such two buffer gear generation effects simultaneously will be safer.In order to play the effect of dash plate further, dash plate is also provided with withstand top 5 of hoistway wall 1 and the barb 8 in order to catch on hoistway wall 1.Top 5 and the barb 8 that arrange can reduce the speed that car 2 drops.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
