Abstract
Large-tonnage instantaneous safety, relates to elevator car safety technical field.The utility model comprises caliper, jaw wedge, fixed guide, row of rollers, and caliper opposite flank is provided with guide pass, and guide pass is inverse Ba type inclined-plane; Row of rollers is arranged between jaw wedge and guide pass, and fixed guide is arranged at row of rollers both sides and is connected with caliper; Jaw wedge is supported by fixed guide and along fixed guide up-and-down movement.The utility model braking reliability is high, is mainly used in large-scale Cargo Lift (car deadweight+load) and is less than lift car in 50000Kg, self-locking in arbitrary lifting space.
Description
Technical field
The utility model relates to elevator car safety technical field.
Background technology
Safety tongs is a kind of mechanical safety member making car or counterweight stop motion, when elevator appearance accident during overspeed, and the running of velocity limiter triggering secure pincers.The safety tongs being mostly little tonnage of current use, is less than the lift car in 50000Kg for large-scale Cargo Lift (car deadweight+load), can self-locking in arbitrary lifting space, and domestic also do not have large-tonnage elevator safety parts like this can for selecting at present.
Utility model content
The utility model object is for above problem, provides a kind of braking distance and stop time to be all better than asymptotic expression safety tongs, the large-tonnage instantaneous safety that braking reliability is high.
The utility model comprises caliper, jaw wedge, fixed guide, row of rollers, and described caliper opposite flank is provided with guide pass, and described guide pass is inverse Ba type inclined-plane; Described row of rollers is arranged between jaw wedge and guide pass, and described fixed guide is arranged at row of rollers both sides and is connected with caliper; Described jaw wedge is supported by fixed guide and along fixed guide up-and-down movement.
Be in the top of the caliper opening of falling the Eight characters before the action of the utility model jaw skewback, during action, jaw skewback is along fixed guide to small end landing, utilizes wedge shape Force principle, is clamped in by car on guide rail, and the gripping power on jaw passes to caliper by row of rollers.When safety tongs effect makes car stop, its application force is directly passed to caliper by jaw wedge, make it to reach stop application force instantaneously, car braking distance in orbit and stop time is made all to be better than asymptotic expression safety tongs, when jaw skewback moves along inclined-plane simultaneously, friction acts in row of rollers, reduces the clamping resistance of jaw, increases the reliability of braking.The utility model is mainly used in large-scale Cargo Lift (car deadweight+load) and is less than lift car in 50000Kg, self-locking in arbitrary lifting space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises caliper 1, jaw wedge 2, fixed guide 3, row of rollers 4, and caliper 1 opposite flank is provided with guide pass 1-1, and guide pass 1-1 is inverse Ba type inclined-plane; Row of rollers 4 is arranged between jaw wedge 2 and guide pass 1-1, and fixed guide 3 is arranged at row of rollers 4 both sides and is connected with caliper 1; Jaw wedge 2 is supported by fixed guide 3 and along fixed guide 3 up-and-down movement.
