Description
Technical field
The present invention relates to a kind of falling proof devices, the more particularly to a kind of anti-fall mechanism of elevator equipped with buffer unit.
Background technology
In recent years, with the propulsion of urbanization and the raising of Living consumption, elevator has become in common people's production, life
Indispensable vertical transportation instrument, in order to ensure operational safety, general vertical lift is designed with falling proof device, mainly by limiting
The devices such as the buffer of fast device, safety tongs and shaft bottom are realized.Once it was found that elevator overspeed declines, limiter of speed can allow electricity first
Ladder driving host shuts down, if host does not still stop, limiter of speed will promote safety tongs and be allowed to clamping guide-rail, force
Car is stuck on guide rail, and in addition if directly impinged on buffer in certain speed, car can also stop.But
Any one link error of this system or component failure, are likely to the paralysis for leading to entire drop preventer, work as sedan-chair
When compartment is landed at a terrific speed, although buffer hits the impact force in shaft bottom when can reduce used during elevator falling, effect is limited,
The injures and deaths of passenger in elevator may still be caused.Although current vertical lift has been provided with above two fall arrest protection dress
It puts, but the generation of used during elevator falling accident cannot be avoided completely.
Invention content
The purpose of invention：In order to avoid the generation of above-mentioned used during elevator falling accident, a kind of elevator equipped with buffer unit is disclosed
Anti-fall mechanism, in the case where existing fall protection equipment fails, the passenger in elevator can save oneself, i.e., manually
Braking of the manipulation device realization to elevator inside lift car is operated, prevents falling for elevator.
Technical solution：In order to achieve the goal above, the invention discloses a kind of anti-fall mechanism of the elevator equipped with buffer unit,
Including crank, connecting rod, locking sliding block, control stick, block, clip hook device, wherein locking sliding block is arranged on car frame and can be with
Level is slided, and connecting rod one end is connect with locking sliding block and connecting rod can be using tie point as branch spot wobble, one end of the other end and crank
Connection and mutually can using tie point as branch spot wobble, the other end of the crank connect with car frame and crank can using tie point as prop up
Spot wobble, one end of control stick connect with crank and mutually can be using tie points as branch spot wobble, and the other end is arranged on cab interior
And connect with clip hook device, block is arranged on the borehole wall, and block is arranged on the borehole wall, and block upper surface is equipped with float plate, is floated
Plate is connected by one group of spring with block.This design structure is simple, and can reliably carry out the hand brake of car,
The elevator of tenesmus is made to stop in time, personnel's saves oneself in realization elevator.The personnel for taking elevator can be with easy manipulation control stick, no
Very big power need to be applied.The personnel for taking elevator need to only move down control stick shorter distance, and the toggle is just
Locking sliding block can be released to enough distances, guarantee to block the block of the borehole wall during car tenesmus to realize braking, float
The design of movable plate makes braking effect more preferable and safer.And impact force during elevator brake will not be transmitted on control stick,
It ensure that the safety of operator.
Further, the anti-fall mechanism of above-mentioned a kind of elevator equipped with buffer unit, the control stick are rotated with clip hook device
It connects and clip hook device can be using tie point as branch spot wobble, clip hook device includes pothook and motion arm.This design can be
Grab blocks car walls during elevator normal operation, realizes the locking to control stick, prevents control stick from dropping and releasing locking sliding block.
Further, the anti-fall mechanism of above-mentioned a kind of elevator equipped with buffer unit, the clip hook device are equipped with spring, the bullet
Spring one end is mounted on motion arm, and the other end is mounted on control stick.This design applies active force to clip hook device, makes its guarantor
Hold the state of tight car walls, lever locked, prevents control stick downslide from locking sliding block being caused to be pushed outwardly and interfere elevator just
Often operation.
Further, the anti-fall mechanism of above-mentioned a kind of elevator equipped with buffer unit, the free end of the control stick and operation
Angle between arm is more than the angle between control stick and pothook.This design can turn round the process of unlock in clip hook device
In and unlock after, still there are one suitable angle between motion arm and control stick, personnel easy to operation grasp.It is also convenient for grasping
Make personnel's force, ensure quick and completely unlock.
Further, the anti-fall mechanism of above-mentioned a kind of elevator equipped with buffer unit, the control stick are equipped with installation spring and use
The first installation axle, the motion arm be equipped with installation spring the second installation axle.This design structure is compact, spring installation side
Just, and the guiding to spring and regulation can be played the role of.
Further, a kind of anti-fall mechanism of above-mentioned elevator equipped with buffer unit, the pothook are L-shaped.This design
It is simple in structure, space is saved, also can guarantee the intensity that the design needs.
Further, a kind of anti-fall mechanism of above-mentioned elevator equipped with buffer unit, the block are arranged on the borehole wall, and are hung down
Directly it is distributed in the borehole wall.Car falls the suitable blocks of Shi Douyou for braking, and made on a upper block at an arbitrary position
During dynamic failure, it can continue to brake in next block, improve the reliability of anti-fall braking.
Above-mentioned technical proposal can be seen that the present invention and have the advantages that：A kind of be equipped with of the present invention buffers
The anti-fall mechanism of elevator of device, it is rational in infrastructure, it is used conveniently and safely, can realize under existing falling-proof safety device disabled status
Personnel save oneself in elevator, and manual manipulation mode is safe and reliable, realize double protection during elevator accidental falling, braking effect
It is good.
