Abstract
The utility model discloses a bidirectional safe clamp, comprising a clamp body. A vertical concaving groove matching to a guide track is arranged in the middle of the clamp body. A <-shaped guide-slip face and a >-shaped guide-slip face are respectively arranged at the inner sides of the left and right frames of the clamp body; two wedges are arranged between the <-shaped and >-shaped guide-slip faces and the guide track. In the two vertical edges of the two wedges, one vertical edge is a <-shaped face or a >-shaped face matching to the guide-slip face; the other edge is a straight face which is convenient to be matched to the guide track. Rolling bodies are arranged between the <-shaped face and the >-shaped face and the guide-slip face; the lower parts of the rolling bodies are connected to one end of a pulling lever. The bidirectional safe clamp of the utility model is of reliable self-locking performance, and can avoid braking failure. The utility model can be used to prevent the lift cabinet from impacting ground or ceiling caused by excessive speed.
Description
Technical field
The utility model relates to a kind of brake device for elevator.Be the bidirectional safety tongs that prevents lift car uplink and downlink hypervelocity specifically.
Background technology
For preventing the up-downgoing hypervelocity of elevator, the generation of the accident of avoiding squatting over a pit to relieve oneself or rush to summit all is equipped with safety tongs on the elevator.Present elevator safety gear has unidirectional and two-way branch.Wherein bidirectional safety tongs has the bi-directional braking function owing to it, and is the most popular with users.This bidirectional safety tongs mainly by shaped as frame caliper, "＜" shape that is installed in shaped as frame caliper inboard and "＞" shape slider guide, has the lifting rod that links to each other with velocity limiter on the voussoir of the right and left.Be provided with a voussoir between "＜" shape slider guide and cage guide and between "＞" shape slider guide and cage guide, the outside of this two voussoir is respectively "＜" shape limit and "＞" shape limit.When ascending for elevator or descending hypervelocity, by means of velocity limiter and lifting rod, can make on two voussoirs and move or move down, thereby clamp cage guide, reach or descend the braking purpose of both direction.
From mechanics, the friction coefficient between the lozenges of slider guide and the lozenges of voussoir is littler than the friction coefficient between guide rail and voussoir straight flange, could produce locking phenomenon, and the difference of these two friction coefficient is bigger, and the reliability of self-locking is higher.Between the slider guide of above-mentioned bidirectional safety tongs and the lozenges of voussoir is the aspectant slip that contacts, and friction coefficient is higher, compares with the friction coefficient between voussoir is faced directly with guide rail, is more or less the same.Therefore, the self-locking reliability is relatively poor, the brake failure phenomenon can occur.
Summary of the invention
The purpose of this utility model is to provide a kind of bidirectional safety tongs.This bidirectional safety tongs, the self-locking good reliability can be avoided the generation of brake failure phenomenon.
Above-mentioned purpose of the present utility model is realized by following technical solution:
Bidirectional safety tongs of the present utility model comprises caliper.Have the groove that cooperates with cage guide in the middle of upper and lower frame one side of caliper, the inboard of its left and right side frame all is fixed with slider guide up and down.The hypotenuse of said up and down slider guide simultaneously is the slide guide face, and the slide guide face of the slider guide up and down on the left side is combined into "＜" shape face, and the slide guide face of the slider guide up and down on the right is combined into "＞" shape face.Between "＜" shape face on the left side and guide rail and between "＞" shape face on the right and guide rail voussoir is arranged all, the one side that the voussoir of the right and left is relative with slider guide is respectively "＜" shape and "＞" shape, and their one sides relative with guide rail are to be faced directly.On "＞" shape symmetric line of the voussoir on "＜" shape symmetric line of the voussoir on the left side and the right guide finger is arranged all, this guide finger protrudes on the voussoir two sides of the right and left.The outside, voussoir both sides of the right and left is provided with cover plate, this two cover plate all is fixed on the caliper, their top "＜" shape and "＞" shape guide groove of being processed with accordingly respectively, the guide finger on the voussoir of the right and left inserts accordingly respectively and is somebody's turn to do in "＜" shape and "＞" shape guide groove.There is the lifting rod that links to each other with velocity limiter the voussoir lower end of the right and left.Its constructional feature is between the voussoir on the slider guide up and down on the left side and the left side and between the voussoir on the slider guide up and down on the right and the right, is respectively arranged with the rolling plate.Be connected by means of spring between two rolling plates.The center fixed of spring is on the caliper left and right side frame between the slider guide up and down.Said rolling plate is formed by retainer and rolling body.The retainer both sides are provided with baffle plate, flanging in one side of baffle plate is oriented, and this flanging colludes on retainer.The another side of baffle plate is fixed on up and down on the slider guide.
Adopt such scheme, have the following advantages:
Because between the slider guide up and down on the left side and left voussoir and between the slider guide up and down and right voussoir on the right, be respectively arranged with the scroll-up/down plate, and the rolling plate is by retainer and is installed in roller on this retainer or rolling body such as ball constitutes, make between slider guide and voussoir it is friction of rolling, effectively reduce friction coefficient, make the friction coefficient between slider guide and voussoir littler than the friction coefficient between guide rail and voussoir straight flange all the time, thereby improved the reliability of self-locking, avoided the situation of brake failure to take place.
