Description
Technical field
This utility model relates to a kind of elevator progressive safety gear, belongs to elevator safety technical field.
Background technology
Safety tongs is the important safety parts of lift facility, it is possible to elevator overspeed and out of control time play safety guarantee weight
Act on, it may be said that just because of appearance and the development of safety tongs, just make elevator become a kind of skyscraper requisite vertical
Straight means of transport.The action of safety tongs device is to make rope-clamping pliers clamp governor rope by limiter of speed action, along with car is downward
Run, governor rope lifting safety tongs link mechanism, safety tongs link mechanism action, drive safety tongs braking member to connect with guide rail
Touch, make the safety tongs on guide rail both sides be simultaneously clamped on guide rail, reach car stop.Safety tongs be typically mounted at car bottom girder or
On two heel posts, when safety tongs is failure to actuate, voussoir keeps the gap of 2～3mm with working face of guide rail.Safety tongs two side clearance
Want uniformly, during action, to make the reliable stop of car on guide rail.But due to the structure of current safety tongs also have some unreasonable it
Place, causes it to be often susceptible to fault, and failure cause is complicated and changeable, and the factor inspiring its misoperation is the most more, therefore deposits
In certain potential safety hazard, it is possible to have serious consequences to elevator and passenger.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of safety is high gradually
Entering type elevator safety gear, its design science is reasonable, good braking effect, it is possible to make the reliable stop of car at guide rail during safety action
On, reducing fault rate, safety is high.
For solving above-mentioned technical problem, this utility model provides a kind of elevator progressive safety gear, including safety gear block,
Stick, voussoir, guide voussoir, flexible member, elastic shelf, guide ball, cage guide；Described voussoir and guiding voussoir are positioned at
In safety gear block, described voussoir is up-narrow and down-wide trapezoidal, and described voussoir is close to cage guide；Described guiding voussoir and voussoir it
Between set guiding ball, and guide the face keeping parallelism that voussoir is relative with voussoir；Stick is set on described voussoir；Described flexible member
It is arranged on elastic shelf, and contacts with guiding voussoir；The leading flank of described safety gear block is fixed with baffle plate, and baffle plate is provided with guiding
Being fixed with guide finger on groove, with the voussoir of gathering sill opposite position, guide finger passes gathering sill.
The one side that aforesaid voussoir contacts with cage guide is provided with anti-skidding teeth.
Aforesaid gathering sill is for being obliquely installed, and incline direction is consistent with guiding ball.
Aforesaid guide finger is cylindrical guide pin.
Aforesaid each voussoir is provided with two guide fingers.
The arragement direction of aforesaid two guide fingers is consistent with gathering sill.
Aforesaid flexible member is c-type leaf spring.
The beneficial effect that this utility model is reached:
Progressive safety gear of the present utility model is additionally arranged gathering sill and guide finger, makes voussoir have during moving up and down
There is good guidance quality.And voussoir of the present utility model is provided with anti-skidding teeth, anti-skidding effect on the occlusal surface of cage guide
The best, it is ensured that the effect of stop.
Accompanying drawing explanation
Fig. 1 is the structural representation of progressive safety gear of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As it is shown in figure 1, elevator progressive safety gear of the present utility model, including safety gear block (accompanying drawing does not demonstrates),
Stick 2, voussoir 7, guide voussoir 10, flexible member 3, elastic shelf 4, guide ball 8, cage guide 1.Concrete, voussoir 7 He
Guiding voussoir 10 and be positioned at safety gear block, voussoir 7 be up-narrow and down-wide trapezoidal, and voussoir 7 is close to cage guide 1, and voussoir 7 is with electric
The one side that ladder guide rail 1 contacts is provided with anti-skidding teeth.Guide and between voussoir 10 and voussoir 7, set guiding ball 8, and guide voussoir 10
The face keeping parallelism relative with voussoir 7.Stick 2 is set on voussoir 7.Flexible member 3 is arranged on elastic shelf 4, and and guiding wedge
Block 10 contacts；Preferably, flexible member 3 is c-type leaf spring.
The leading flank of safety gear block is fixed with baffle plate 9, and baffle plate 9 is provided with gathering sill 5, with gathering sill 5 opposite position
Being fixed with guide finger 6 on voussoir 7, guide finger 6 is through gathering sill 5.When voussoir 7 moves up and down with voussoir 7 in gathering sill 5 on
Lower motion, plays good guidance quality.
Gathering sill 5 is for being obliquely installed, and incline direction is consistent with guiding ball；Guide finger 6 is cylindrical guide pin.
Preferably, each voussoir is provided with two guide fingers, and the arragement direction of two guide fingers is consistent with gathering sill.
Operation principle of the present utility model is: mentions when voussoir is manipulated by bar, is fitted on cage guide and plays braking action,
Thrust is passed to guide voussoir by voussoir by molgogger, guides device on rear side of voussoir and has elastic component, makes voussoir act on
Pressure on cage guide is provided with certain elasticity, produces the softest stop effect.Voussoir is engaged with cage guide
Anti-skidding teeth, good antiskid effect it is provided with, it is ensured that the effect of stop on face.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and deformation, these change
Enter and deform and also should be regarded as protection domain of the present utility model.
