Abstract
The utility model relates to a pair of elevator instantaneous safety pliers. A groove is arranged on pliers bodies which are fixedly connected with the bottom of an elevator cage, and an elevator guide rail is positioned in the groove which is an inclined plane groove. Double rolling pillar assemblies which can move up and down and wedge blocks are respectively arranged in the groove. Therefore, the utility model has the advantages of simple structure, reasonable and compact structure, good braking effect, high braking capacity, etc.
Description
The utility model relates to a kind of elevator safety holding device of handling by velocity limiter, particularly a kind of wink fashoined safety gripper clamp.
Along with the continuous development of urban construction scale, the continuous construction of high buildings and large mansions, the demand of elevator also constantly increases thereupon.Because elevator drags car by motor and moves up and down, therefore hypervelocity takes place under elevator is nonserviceabled easily glide or falling accident, this is with regard to entail dangers to occupant's safety.Usually disposing safety tongs on the elevator is the indispensable component part of modem elevator, the safety tongs that disposes on elevator at present is divided into instantaneous formula, has three kinds of the instantaneous formula of buffer action and progressive safety gears by the effect situation, wherein the structure of instantaneous safety is mainly by the eccentric block formula, three kinds of Wedge-type and single rollers, all there are many problems in these three kinds of instantaneous safeties at aspects such as braking effect braking potentiaies.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and a kind of improved type elevator instantaneous safety that can improve a lot on braking effect and braking potential is provided.
The purpose of this utility model is finished by following technical solution, it mainly contains a caliper that is connected in lift car, offer groove on the caliper, and cage guide is positioned at groove, and groove is an inclined plane groove, become up-small and down-big pyramid-shaped, the both sides of guide rail are equipped with group of rollers moving up and down and voussoir respectively in groove.
Described group of rollers is to be formed by connecting by connecting plate by small one and large one two roller, and group of rollers and voussoir and guide rail are with plane contact.
Accompanying drawing is a structural representation of the present utility model.
To be described in detail the utility model by accompanying drawing below, one caliper, 1 usefulness screw 2 is fixed on the bottom of lift car, and with the lift car up-and-down movement, offer inclined plane groove 3 in the centre of caliper 1, and form up-small and down-big pyramid-shaped, cage guide 4 positions are in inclined plane groove 3, in inclined plane groove 3, the both sides of cage guide 4 are equipped with group of rollers 5 and voussoir 6 respectively, and this group of rollers 5 is the twin roller groups that are formed by connecting by up-small and down-big two rollers 7 and connecting plate 8.Group of rollers 5 and voussoir 6 can be along the inclined-planes of caliper 1 inner groovy and are moved, under the elevator normal operation, voussoir 6 and group of rollers 5 all maintain a certain distance with guide rail, the operation up and down of lift car can normally be carried out, when elevator breaks down when falling fast, velocity limiter works to group of rollers 5 and voussoir 6 to lift power P, and group of rollers 5 and voussoir 6 will move up along the inclined-plane of caliper, and the gap between very fast elimination and the guide rail 4, block guide rail 4.Rely on the friction of roller and voussoir and guide rail 4, the more important thing is the kinetic energy when the distortion absorption lift car that relies on guide rail 4 and caliper falls fast, car is tightly blocked on guide rail, prevented the generation of accident, and when the fault elimination, when carrying on the car, roller and voussoir will glide and loosen guide rail, and elevator can normally move again.
The utility model is a kind of improvement to prior art, and by contrast, it has simple and reasonable for structure Compactness, good braking effect, the advantage such as ability processed is big.
