Description
Technical field
This utility model relates to a kind of elevator instantaneous safety pliers, belongs to elevator safety technical field.
Background technology
Elevator safety gear as an important safety component of elevator, is the indispensable vitals of elevator.Elevator
Safety tongs is divided into instantaneous formula and gradual two types, owing to the material cost of progressive safety gear is high, so instantaneous safety
The use of pincers is commonplace, and instantaneous safety is made up of caliper, voussoir, baffle plate, and the action of voussoir is drawn respectively by two pull bars
Dynamic two voussoirs.Existing instantaneous safety uses group of rollers as a part for braking member, although braking flexibly, but is tied
Structure is relative complex, and manufacturing cost is high, it addition, the guidance quality that the voussoir of safety tongs is during moving up and down also is treated to carry further
High.
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 simple in construction, becomes
This is low and voussoir moves up and down the elevator instantaneous safety pliers that guidance quality is good.
For solving above-mentioned technical problem, this utility model provides a kind of elevator instantaneous safety pliers, including caliper, and voussoir,
Spherical guide, ball and baffle plate, described caliper offers up-narrow and down-wide passage, this passage longitudinally through cage guide, and and
Cage guide is positioned on same centrage；The side of described caliper is provided with spherical guide, and ball is positioned at spherical guide and voussoir
Between, make voussoir move up and down along spherical guide；The leading flank of described caliper is fixed with baffle plate, and baffle plate is provided with gathering sill, with
Being fixed with guide finger on the voussoir of gathering sill opposite position, guide finger passes gathering sill.
Aforesaid voussoir is up-narrow and down-wide shape.
Aforesaid gathering sill is for being obliquely installed, and incline direction is consistent with spherical guide.
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.
The beneficial effect that this utility model is reached:
Elevator instantaneous safety pliers of the present utility model is additionally arranged gathering sill and guide finger, makes voussoir move up and down process
In there is good guidance quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of elevator instantaneous safety pliers 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 instantaneous safety pliers of the present utility model, including caliper 2, voussoir 4, spherical guide, ball 5
With baffle plate 3.Caliper 2 offers up-narrow and down-wide passage, and this passage is longitudinally through cage guide 1, and is positioned at same with cage guide
On one centrage.Voussoir 4 is similarly up-narrow and down-wide shape, and the side of caliper 2 is provided with spherical guide, and ball 5 is positioned at ball leads
Between rail and voussoir 4, voussoir 4 is made to move up and down along spherical guide.The leading flank of caliper 2 is fixed with baffle plate 3, and baffle plate 3 is provided with
Gathering sill 7, gathering sill 7 is for being obliquely installed, and incline direction is consistent with spherical guide.Voussoir 4 with gathering sill 7 opposite position
On be fixed with guide finger 6, guide finger 6, through gathering sill 7, is transported with voussoir 4 up and down when voussoir 4 moves up and down in gathering sill 7
Dynamic, play good guidance quality.
Preferably, each voussoir is provided with two guide fingers, and the arragement direction of two guide fingers is consistent with gathering sill.
Further, guide finger is cylindrical guide pin.
Operation principle of the present utility model is: when elevator drops rapidly because of fault, and limiter of speed triggers safety tongs action,
Voussoir is moved up along spherical guide, and the gap shrinks between two voussoirs, until contacting with cage guide and occurring
Friction, brakes lift car.After elevator faults releases, two voussoirs move down, and spacing becomes big and discharges cage guide.
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.
