Description
Technical field
The present invention relates to a kind of falling proof device, more particularly to a kind of locking system for elevator hand fall arrest.
Background technology
In recent years, as the propulsion of urbanization and the raising of Living consumption, elevator have become in common people's production, life
Indispensable vertical transportation instrument, safe for operation in order to ensure, 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 lift safety tongs and be allowed to clamping guide-rail, force
Carriage is stuck on guide rail, and in addition if directly impinged on buffer in certain speed, carriage can also stop.But
Any one link error of this system or component failure, are likely to the paralysis for causing whole drop preventer, work as sedan-chair
When railway carriage or 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
Put, but the generation of used during elevator falling accident cannot be avoided completely.
The content of the invention
The purpose of invention：In order to avoid the generation of above-mentioned used during elevator falling accident, open one kind is used for elevator hand fall arrest
Locking system, existing fall protection equipment fail in the case of, the passenger in elevator can save oneself, i.e. hand
Manipulation device inside dynamic operation lift car realizes the braking to elevator, prevents falling for elevator.
Technical solution：In order to realize the above object the invention discloses a kind of locking dress for elevator hand fall arrest
Put, including crank, connecting rod, locking sliding block, control stick, block, clip hook device, wherein locking sliding block are arranged on car frame and can
Slided with level, connecting rod one end be connected with locking sliding block and connecting rod can using tie point as branch spot wobble, the one of the other end and crank
End connection and mutually can using tie point as branch spot wobble, the other end of the crank be connected with car frame and crank can using tie point as
Branch spot wobble, one end of control stick are connected with crank and can be arranged on by branch spot wobble, the other end of tie point in carriage mutually
Portion and it is connected with clip hook device, block is arranged on the borehole wall and is adapted with locking slider shape.This design structure is simple, and
And the hand brake of carriage can be reliably carried out, the elevator of tenesmus is stopped in time, realize saving oneself for personnel in elevator.Take
The personnel of elevator can be not required to apply very big power with easy manipulation control stick.The personnel for taking elevator only need to be by control stick down
Locking sliding block can just be released enough distances, guarantee to drop in carriage by mobile shorter distance, the toggle
The block that the borehole wall is blocked in journey is braked with realizing.And impact during elevator brake will not be delivered on control stick, ensure
The safety of operator.
Further, above-mentioned a kind of locking system for elevator hand fall arrest, the control stick are revolved with clip hook device
Turn connection 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 with
In elevator normal operation, grab blocks car walls, realizes the locking to control stick, prevents control stick from dropping and releases locking cunning
Block.
Further, a kind of above-mentioned locking system for elevator hand fall arrest, the clip hook device are equipped with spring, should
Spring one end is installed on motion arm, and the other end is installed on control stick.This design applies active force to clip hook device, makes it
The state of clamping car walls is kept, lever locked, prevents control stick glides from causing locking sliding block to be pushed outwardly and hinder elevator
Normal operation.
Further, above-mentioned a kind of locking system for elevator hand fall arrest, the free end of the control stick and behaviour
Make the angle that the angle between arm is more than between control stick and pothook.This design can turn round the mistake of unlock in clip hook device
In journey and after unlock, still there is a suitable angle between motion arm and control stick, personnel easy to operation grasp.It is also convenient for
Operating personnel exert a force, and ensure quick and completely unlock.
Further, above-mentioned a kind of locking system for elevator hand fall arrest, the control stick are equipped with installation spring
First installation axle, the motion arm are equipped with the second installation axle of installation spring.This design structure is compact, spring installation
It is convenient, and the guiding to spring and regulation can be played the role of.
Further, a kind of above-mentioned locking system for elevator hand fall arrest, the pothook are L-shaped.It is this to set
Count it is simple in structure, save space, also can guarantee that the design need intensity.
Further, above-mentioned a kind of locking system for elevator hand fall arrest, the block vertical distribution is in the borehole wall
On.Carriage falls the suitable blocks of Shi Douyou for braking at an arbitrary position, and when braking failure on a upper block,
Next block can continue to brake, and improve the reliability of anti-fall braking.
Above-mentioned technical proposal can be seen that the present invention and have the advantages that：One kind of the present invention is used for elevator
The locking system of manual fall arrest, its is rational in infrastructure, is used conveniently and safely, and can realize existing falling-proof safety device disabled status
Personnel save oneself in lower elevator, and manual manipulation mode is safe and reliable, realize double protection during elevator accidental falling.
