Description
Technical field
The present invention relates to a kind of falling proof device, particularly to a kind of anti-fall mechanism of elevator being provided with buffer unit.
Background technology
In recent years, propelling and the raising of Living consumption along with urbanization, elevator has become vertical transportation instrument indispensable in common people's production, life, in order to ensure to run safety, general vertical lift is designed with falling proof device, is mainly realized by devices such as the buffers of limiter of speed, safety tongs and shaft bottom.Once find that elevator overspeed declines, first limiter of speed can allow elevator driving host shut down, if main frame does not the most stop, limiter of speed will promote safety tongs and be allowed to clamping guide-rail, car is forced to be stuck on guide rail, if additionally directly impinged in certain speed on buffer, car also can stop.But, any one link of this system is made mistakes or components and parts are malfunctioning, it is likely to cause the paralysis of whole drop preventer, when car lands at a terrific speed, although buffer clashes into the impulsive force in shaft bottom when can reduce used during elevator falling, but effect is limited, still it is likely to result in the injures and deaths of passenger in elevator.Although vertical lift has been provided with above two fall protection equipment at present, but can not avoid the generation of used during elevator falling accident completely.
Summary of the invention
The purpose of invention: in order to avoid the generation of above-mentioned used during elevator falling accident; a kind of anti-fall mechanism of elevator being provided with buffer unit is disclosed; in the case of existing fall protection equipment lost efficacy; passenger in elevator can be saved oneself; i.e. manipulation device within manual operation lift car realizes the braking to elevator, prevents falling of elevator.
Technical scheme: in order to realize object above, the invention discloses a kind of anti-fall mechanism of elevator being provided with buffer unit, including crank, connecting rod, locking slide block, stick, block, clip hook device, wherein locking slide block is arranged on car frame and can level slide, connecting rod one end is connected with locking slide block and connecting rod can be with junction point for a spot wobble, the other end is connected with one end of crank and mutually can be with junction point for a spot wobble, the other end of this crank is connected with car frame and crank can be with junction point for a spot wobble, one end of stick is connected with crank and mutually can be with junction point for a spot wobble, the other end is arranged on cab interior and is connected with clip hook device, block is arranged on the borehole wall, block is arranged on the borehole wall, block upper surface is provided with float plate, float plate is connected with block by one group of spring.This design simple in construction, and the hand brake of car can be carried out reliably, make the elevator of tenesmus stop in time, it is achieved in elevator, personnel's saves oneself.The personnel taking elevator can be not required to apply the biggest power with easy manipulation stick.Take the personnel of elevator only need to be moved down by stick shorter distance, locking slide block just can be released enough distances by this toggle, guaranteeing to block the block of the borehole wall during car drops to realize braking, the design of float plate makes braking effect more preferable and safer.And impact force during elevator brake is also not transferred on stick, it is ensured that the safety of operator.
Further, above-mentioned a kind of anti-fall mechanism of elevator being provided with buffer unit, described stick is rotatably connected with clip hook device and clip hook device can be with junction point for a spot wobble, and clip hook device includes pothook and motion arm.This design can block car walls by grab when elevator is properly functioning, it is achieved the locking to stick, prevents stick tenesmus from releasing locking slide block.
Further, above-mentioned a kind of anti-fall mechanism of elevator being provided with buffer unit, described clip hook device is provided with spring, and this spring one end is arranged on motion arm, and the other end is arranged on stick.This design applies active force to clip hook device so that it is keep the state of clamping car walls, lever locked, prevents stick from gliding and causes locking slide block extrapolated and hinder elevator properly functioning.
Further, above-mentioned a kind of anti-fall mechanism of elevator being provided with buffer unit, the angle between free end and the motion arm of described stick is more than the angle between stick and pothook.This design can still have a suitable angle, it is simple to operator grasp during clip hook device revolution unlocks and after unblock between motion arm and stick.It is also convenient for operator's force, it is ensured that quickly and completely unlock.
Further, above-mentioned a kind of anti-fall mechanism of elevator being provided with buffer unit, described stick is provided with the first installation axle installing spring, and described motion arm is provided with the second installation axle installing spring.This design compact conformation, spring is easy for installation, it is possible to play the guiding to spring and regulation effect.
Further, above-mentioned a kind of anti-fall mechanism of elevator being provided with buffer unit, described pothook is L-shaped.This design simple in construction, saves space, also can guarantee that the intensity that the design needs.
Further, above-mentioned a kind of anti-fall mechanism of elevator being provided with buffer unit, described block vertical distribution is on the borehole wall.The car suitable block of Shi Douyou that falls at an arbitrary position is for braking, and when braking unsuccessfully on a upper block, can proceed braking at next block, improve the reliability of anti-fall braking.
Technique scheme can be seen that; there is advantages that a kind of anti-fall mechanism of elevator being provided with buffer unit of the present invention; it is rational in infrastructure; it is used conveniently and safely; saving oneself of personnel in elevator can be realized under existing falling-proof safety device disabled status; manual manipulation mode is safe and reliable, it is achieved double protection during elevator accidental falling, its good braking effect.
