Description
Technical field
This utility model relates to a kind of elevator safety gear, the elevator safety gear that a kind of retro-speed is fast.
Background technology
In existing elevator, it is typically to be pulled the brake block in safety tongs by shift mechanism in overspeed, by system
Motion block clamping guide-rail is braked, it is ensured that the safety that elevator runs.In existing elevator safety gear, the most frequently used for gradual
Elevator safety gear, drives wedge shape brake block to move straight up along wedge shape guide pad, due to wedge shape brake block by lifting rod
It is slidably connected by inclined-plane with wedge shape guide pad, so wedge shape brake block can direction guiding rail level move while moving up
Dynamic, grip track, thus elevator brake.But, the retro-speed of this kind of elevator safety gear is relatively slow, and brake force carries along with lifting rod
The increase drawing distance is gradually increased, and causes braking effect undesirable.Therefore, existing elevator safety gear also exists retro-speed relatively
Slow and that braking effect is undesirable problem.
Utility model content
The purpose of this utility model is, it is provided that the elevator safety gear that a kind of retro-speed is fast.This utility model can not only
Enough improve retro-speed, the advantage also with good braking effect.
The technical solution of the utility model: the elevator safety gear that a kind of retro-speed is fast, including frame, frame is provided with
Symmetrical 2 wedge shape guide pads, are provided with spring between each wedge shape guide pad and the sidewall of frame；2 wedge shapes are led
Being provided with the groove connecting guide rail between block, the both sides of groove are provided with wedge shape brake block, and wedge shape brake block side is passed through
Hypotenuse is slidably connected with wedge shape guide pad；Being provided with linkage board between 2 wedge shape brake block, linkage board top ends connects lifting
Bar；Described linkage board is provided with the gathering sill of arc, and connecting in gathering sill has symmetrical 2 columns, 2 columns respectively with
2 fixing connections of wedge shape brake block.
In the elevator safety gear that aforesaid a kind of retro-speed is fast, between described spring and the sidewall of frame, it is provided with regulation
Plate, the sidewall of frame is connected by screwed hole and has regulation screw, and regulation screw one end is connected with adjustable plate.
In the elevator safety gear that aforesaid a kind of retro-speed is fast, described gathering sill is semicircle, and semicircular opening erects
The most upwards.
In the elevator safety gear that aforesaid a kind of retro-speed is fast, the width of described gathering sill is equal to the diameter of column.
Compared with prior art, this utility model improves the structure of existing elevator safety gear, by arranging lifting rod
Pull linkage board to drive wedge shape brake block to move along wedge shape guide pad, carry out gradual braking；Simultaneously by gathering sill and
Column makes speed that wedge shape brake block moves horizontally be gradually increased along with the gathering sill of arc, it is possible to moving up a segment distance
Rear realization is the most traversing, and traversing rear wedge shape guide pad is traversing against wedge shape brake block under the action of the spring, it is ensured that indicating brake action
And insensitivity, thus retro-speed can not only be improved, additionally it is possible to improve braking effect.Additionally, this utility model passes through
Regulation screw is set and adjustable plate can regulate wedge shape guide pad position under spring naturalness, it is possible to according to different elevators
Brake request be adjusted, applied widely；The width being directed to groove is equal to the diameter of column, it is possible at linkage board
Drive column and wedge shape brake block to move during upper shifting simultaneously, improve sensitivity.Therefore, this utility model can not only improve
Retro-speed, also has good braking effect, the advantage that applied widely and sensitivity is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-frame, 2-wedge shape guide pad, 3-spring, 4-groove, 5-wedge shape brake block, 6-links
Plate, 7-lifting rod, 8-gathering sill, 9-column, 10-adjustable plate, 11-regulates screw.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings, but is not intended as this utility model
The foundation limited.
Embodiment.The elevator safety gear that a kind of retro-speed is fast, is constituted as it is shown in figure 1, include frame 1, and frame 1 is arranged
There are symmetrical 2 wedge shape guide pads 2, between each wedge shape guide pad 2 and the sidewall of frame 1, are provided with spring 3；2
Being provided with the groove 4 connecting guide rail between wedge shape guide pad 2, the both sides of groove 4 are provided with wedge shape brake block 5, and wedge shape is braked
Block 5 side is slidably connected with wedge shape guide pad 2 by hypotenuse；Linkage board 6, linkage board 6 it is provided with between 2 wedge shape brake block 5
Top ends connects lifting rod 7；Described linkage board 6 is provided with the gathering sill 8 of arc, and connecting in gathering sill 8 has symmetrical 2
9,2 columns 9 of individual column are fixing with 2 wedge shape brake block 5 respectively to be connected.
It is provided with adjustable plate 10 between described spring 3 and the sidewall of frame 1, the sidewall of frame 1 is connected by screwed hole
Regulation screw 11, regulation screw 11 one end is had to be connected with adjustable plate 10；Described gathering sill 8 is semicircle, and semicircular opening erects
The most upwards；The width of described gathering sill 8 is equal to the diameter of column 9.
Operation principle: during use, lifting rod 7 pulls up linkage board 6, and linkage board 6 drives wedge shape brake block by column 9
5 move up；On the one hand when wedge shape brake block 5 moves up, along wedge shape guide pad 2 upwards and to groove 4 one side shifting, one
Aspect moves along the gathering sill 8 of arc due to column 9, and the speed making wedge shape brake block 5 traversing is gradually increased, particularly wedge shape
The speed traversing after moving up a segment distance of brake block 5 increases rapidly, thus improves retro-speed；Meanwhile, brake in wedge shape
When block 5 is the most traversing because of column 9 and gathering sill 8, wedge shape guide pad 2 is horizontal against wedge shape brake block 5 under the effect of spring 3
Move, it is ensured that brake force and insensitivity, it is to avoid during braking, lifting rod 7 stress is excessive and damage.
