Description
Technical field
This utility model relates to elevator technology field, especially relates to the elevator of elevator safety.
Background technology
In modern society, elevator has become as indispensable riding instrument in people's life, and the safety of its operation is also increasingly subject to the concern of people, and in elevator accident, relatively conventional car phenomenon of slipping, is substantially because caused by the forfeiture of brake braking force.The safety and reliability of elevator becomes the problem that society pays special attention to, even if apparatus for controlling elevator takes Preventive and protective measure, but elevator accident still occurs again and again.Suddenly having a power failure if elevator is in operation or supplies circuit malfunctions, elevator brake will stop by elevator brake.Therefore, elevator brake is properly functioning extremely important.
Existing elevator is to be braked by limiter of speed safety tongs, but losing efficacy easily occurs in this technology, and the safety of elevator is caused bigger hidden danger.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model proposes a kind of elevator, its objective is to improve the safety coefficient of the brake of existing elevator, it is ensured that the safety that elevator runs.
In order to solve above-mentioned technical problem, the basic technical scheme that the utility model proposes is: a kind of elevator, including car frame and car, is provided with the Dao Xue mechanism with guide rail contact in the both sides of the upper and lower car cross bar of car frame,
Described Dao Xue mechanism includes the pedestal being fixed on car cross bar, this pedestal is provided with and swingable supports fork and at guide rail with support the fixing bar of position between fork, being rotationally connected one on described support fork can with the guide wheel of described guide rail Structure deformation, the upper end of described support fork is socketed a guide rod, one end of this guide rod is fixed on described fixing bar, and the other end is free end；This guide rod is in the spring of compressive state near the socket of the side of free end, and in use, this spring forces the guide rail that described guide wheel contact is described；
Wherein, described support fork connects a hydraulic drive mechanism that support fork direction guiding rail can be forced to swing；
Wherein, described support fork also sets up the arrestment mechanism being capable of guide wheel braking.
Further, described hydraulic drive mechanism includes hydraulic cylinder, and the outfan of this hydraulic cylinder is fixed on described support fork.
Further, described arrestment mechanism include the disc that is connected with described guide wheel and be placed in outside disc edge braking clamp.
The beneficial effects of the utility model are:
In the technical solution of the utility model, when occurring safety unexpected by being arranged on can with guide rail contact and produce the Dao Xue mechanism rubbed by force, when there is used during elevator falling, guide rail can be produced powerful frictional force by Dao Xue mechanism, it is ensured that the safety that elevator uses.

Detailed description of the invention
Below with reference to accompanying drawing 1 to Fig. 3, this utility model is described further, but protection domain of the present utility model should do not limited with this.
This utility model one elevator, including car frame 10 and car 20, is provided with, in the both sides of the upper and lower car cross bar 101,102 of car frame 10, the Dao Xue mechanism 40 contacted with guide rail 30.Certainly, described Dao Xue mechanism 40 has three guide wheels, and these three guide wheels contact three faces of guide rail 30 respectively, and retrain the direction of motion of car with this.In order to realize the safety of elevator, at least at least one guide wheel place of each Dao Xue mechanism 40 is provided with safety catch, specific as follows.
Dao Xue mechanism 40 includes the pedestal 401 being fixed on car cross bar, this pedestal 401 is provided with and swingable supports fork 402 and at guide rail 30 with support the fixing bar 403 of position between fork 402, this fixing bar 403 is vertically fixed on described pedestal 401, being rotationally connected one on described support fork 402 can with the guide wheel 404 of described guide rail 30 Structure deformation, the upper end of described support fork 402 is socketed a guide rod 405, one end of this guide rod 405 is fixed on described fixing bar 403, and the other end is free end；This guide rod 405 is in the spring 406 of compressive state near the socket of the side of free end, and in use, this spring 406 forces described guide wheel 404 to contact described guide rail 30；
Concrete, described support fork 402 connects one can force the hydraulic drive mechanism 50 supporting the swing of fork 402 direction guiding rail 30 when input hydraulic pressure；This hydraulic drive mechanism 50 can produce very big pressure, forces guide wheel 404 tightly to extrude described guide rail 30, it is intended to direction guiding rail 30 produces huge pressure.Wherein this hydraulic drive mechanism 50 includes hydraulic cylinder, the outfan of this hydraulic cylinder is fixed on described support fork 402, when hydraulic cylinder produces pressure, will produce pressure to supporting fork 402, by supporting fork 402, these pressure are passed to guide wheel 404, then extruded guide rail 30 by guide wheel 404.
For the frictional force increased between guide wheel 404 and guide rail 30, must ensure that described guide wheel 404 does not rotate, it is achieved between itself and guide rail 30, produce dynamic friction, Cai the obstruction power so produced is sufficiently large, braking could be realized.Therefore, supporting, fork 402 also sets up the arrestment mechanism 60 being capable of guide wheel 404 braking, be capable of braking the guide wheel 404 of rotation by this arrestment mechanism 60.Concrete, this arrestment mechanism 60 include the disc 601 that is connected with described guide wheel 404 and be placed in outside disc 601 edge braking clamp 602.When elevator generation accidental falling, braking clamp 602 will run, and slowly extrudes described disc 601, is achieved in the braking of guide wheel 404.Guide wheel 404 after braking is owing to having very big extruding force between guide rail 30, therefore when there is used during elevator falling, these guide wheels 404 will produce very big frictional force on guide rail 30, thereby ensures that the safety of elevator.
The announcement of book and instruction according to the above description, above-mentioned embodiment can also be modified and revise by this utility model those skilled in the art.Therefore, this utility model is not limited to detailed description of the invention disclosed and described above, should also be as falling in scope of the claims of the present utility model to modifications and changes more of the present utility model.Although additionally, employ some specific terms in this specification, but these terms are intended merely to convenient explanation, this utility model are not constituted any restriction.
