Specific embodiment
In order to illustrate the embodiments of the present invention more clearly with technical solution in the prior art, Detailed description of the invention will be compareed below A specific embodiment of the invention.It should be evident that drawings in the following description are only some embodiments of the invention, for For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other Attached drawing, and obtain other embodiments.In addition, it is related to the relative positional relationship only indicated between each component that belongs in orientation, and It is not absolute positional relation.
Please refer to Fig. 1, Fig. 2 and Fig. 3.The elevator overspeed protecting device of the embodiment of the present invention, in 1 overspeed of carriage When reduce by 1 speed of carriage or make carriage 1 stop, including one be installed on 1 outer wall of carriage steady rest 2, two guarantee about 1 carriage Run the track 3 that does not shift and it is multiple be set on steady rest 2 and run on track 3 to when carriage 1 exceeds the speed limit with The brake 4 that 3 mating reaction of track makes carriage 1 slow down or stop;Brake 4 includes a directive wheel run on the track 3 41, one with the centrifuge box 42, one of 41 synchronous rotary of directive wheel be set on centrifuge box 42 when passing through 42 overspeed rotation of centrifuge box from Under the action of mental and physical efforts and trigger expelling means 421, expelling means 421 be equipped with one by expelling means 421 by centrifugal force controlled Its flexible elastic component 422 further includes one acting on track 3 by the triggering of expelling means 421 and generating the locking of frictional force Unit, locking unit include to be mounted on the support plate 43 of steady rest 2, to pass through rubbing action in track 3 and set It is covered on the locking part in support plate 43 and the connector to control locking part by the triggering of expelling means 421, locking part Equipped with making it act on the spring of track 3 to the control by connector.
Steady rest 2 is set to 1 outer wall of carriage, around protection carriage 1, while being equipped in 1 bottom and top of carriage Reinforcement structure is prevented in 1 unexpected stress of carriage, cabinet becomes with guaranteeing that steady rest 2 and carriage 1 reach better fixed engagement Shape.
Track 3 of the invention includes two and is set on hoistway two sidewalls, and the directive wheel 41 on brake 4 is on the track 3 The number of brake 4 is arranged in operation according to the actual situation, arrived better braking effect and safety, such as layer is high and carries Weight, brake 4 are detachably arranged on steady rest 2, when carriage 1 is under the traction of traction machine, the directive wheel 41 of brake 4 It will be slided along 1 liang of siding track 3 of carriage, guarantee that carriage 1 does not shift.
Please refer to Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8.When appearance exception, 1 overspeed of lift car, at this moment, directive wheel 41 revolving speed also can be more than normal speed, and the centrifuge box 42 of synchronous rotation can also exceed normal speed, in centrifuge box 42 The expelling means 421 of eccentric setting just will receive bigger centrifugal force, when the centrifugal force that expelling means 421 are subject to is greater than elastic component 422 When to the binding forces of expelling means 421, one end of the expelling means 421 of eccentric setting will be thrown away from the opening of centrifuge box 42, be exposed In 42 outside of centrifuge box, convex is formed, at this moment due to the lasting rotation of centrifuge box 42, the expelling means 421 of exposing will be touched Mechanical displacement occurs for connector, since the change of connector displacement triggers, the locking part being stuck on connector, in the work of spring Under, locking part bullet is to track 3, with its friction eceleration.
Elastic component 422 of the invention needs the correction for carrying out coefficient of elasticity in advance before use, under 1 safe speed of carriage its Binding force is greater than centrifugal force, has reached and does not trigger under safe speed,
Locking part one end is equipped with the locking plate 44 for acting on track 3, and the other end is equipped with for making with connector cooperation Limit button 48.
Connector includes that the work that track 3 is acted on to control locking part blocks 46 and one to receive expelling means 421 Triggering and the mechanical displacement generated are transferred to the transferring member 45 of card 46 living, card 46 and 45 active link of transferring member living.
Card 46 living is equipped with the limiting section 461 to be limited to locking part, and 461 two sides of limiting section are equipped with for embracing The trigger unit 462 that dead part passes through.
Connector is equipped with the reinforcement screw of the mechanical displacement to reinforce the generation of expelling means 421.
Locking plate 44 and limit button 48 are attached by passing through the bar of support plate 43, and spring pocket is on bar, spring two End is connected to respectively on locking plate 44 and the side wall of support plate 43.Since locking part the elastic coefficient is larger, in order to avoid touching Hair failure, while also considering the position problems of whole device structure, thus by the combination linkage of transferring member 45 and card 46 living come Triggering, transferring member 45 reinforce screw due to being provided with, play the role of laborsaving lever, be exaggerated trigger effect, for entire dress The sensitivity set provides guarantee.
Track 3 includes the guided way 31 to accommodate directive wheel 41 and the deceleration rail 32 to receive locking unit obvolvent.
41 surface of directive wheel is equipped with multiple annular protrusions, and guided way 31 and 41 contact surface of directive wheel are equipped with multiple and convex annular Act the groove being used cooperatively.
Deceleration rail 32 is equipped with the flap 33 being used cooperatively with locking part for its obvolvent.
Deceleration rail 32 is additionally provided with the accommodation groove to be limited to support plate 43.Its purpose prevents from propping up during locking Fagging 43 deforms, and influences locking effect.
Deceleration rail 32 and guided way 31 can preferably guarantee braking effect, centrifuge box 42 with integrated setting in this way On be additionally provided with to prevent expelling means 421 reset non return part 423.It prevents expelling means 421 from resetting, while also increasing expelling means 421 throw away after can have more preferable support force go triggering locking unit.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention Protection scope.
