Abstract
The utility model discloses an elevator speed limiting device. The elevator speed limiting device comprises a roller, a speed-limiting triggering wheel and a brake, wherein a wheel shaft of the roller is horizontally arranged on a car frame or a car of an elevator; the speed-limiting triggering wheel is arranged on the wheel shaft and can be driven by the roller to rotate together when the rotation speed of the roller exceeds a preset value; the brake is arranged on the car frame or the car of the elevator and can be driven by the rotating speed-limiting triggering wheel to brake the car frame or the car of the elevator on a guide rail of the elevator; and the roller abuts against the guide rail of the elevator in a rolling manner. Once the operation of the elevator is overspeed, the rolling of the roller is also overspeed correspondingly, the speed-limiting triggering wheel can be triggered to rotate, and the car or the car frame is braked by the brake. The elevator speed limiting device disclosed by the utility model has the advantages that the use of steel wire ropes of a speed limiter and a steel-wire-rope tightening device is avoided, the space of a well is saved, the utilization rate of the well is increased, and the elevator speed limiting device can be installed and maintained by people step on the car or the car frame so as to be relatively convenient.
Description
Technical field
the utility model relates to elevator speed governor.
Background technology
In
prior art; What elevator speed governor adopted is elevator governor, and the velocity limiter Monitoring and Controlling the running velocity of car, when overspeed situation occurring; Velocity limiter can in time send signal; Then produce mechanical action and cut off feed circuit, and speed limiter wire rope can lift lifting rod and make and be installed in the safety tongs action on the sedan-chair frame, force stop on guide rail car.In the existing velocity limiter, for machine-roomless lift, the velocity limiter wheel generally is contained in the towing machine next door, and installation and maintenance are all inconvenient like this.Be wound with speed limiter wire rope on the velocity limiter wheel, for the tensioner steel rope, also the steel rope swelling device need be set, this swelling device complex structure relatively takes up space.
Summary of the invention
The purpose of
the utility model provides and makes things convenient for installation and maintenance and the elevator speed governor of saving the space.
are for achieving the above object; The technical scheme that the utility model adopts is: elevator speed governor; Comprise when wheel shaft is horizontally set on roller on elevator car frame or the car, is contained on the said wheel shaft and can surpasses setting value at the rotating speed of said roller that being driven the speed limit of rotating together by this roller triggers wheel, is arranged on the said speed limit that can be rotated on said elevator car frame or the car and triggers wheel drive with this elevator car frame or the drg of car stop on cage guide, said roller and the rollably conflict mutually of said cage guide.
preferably; Said speed limit triggers wheel and goes up the end that rotation is provided with lifting rod; The other end of this lifting rod rotates and is arranged on the said drg, and this drg adopts can be lifted the elevator safety gear with the said elevator car frame of stop by said lifting rod.
preferably, said elevator car frame or car are provided with and are used for tightening device that said roller is stably conflicted and on said guide rail, rolled.
further preferably, said tightening device comprises and is used to provide this wheel shaft elastic-restoring force to make this roller elastic component on said guide rail of stably conflicting between the wheel shaft that is arranged on said roller and said sedan-chair frame or the car.
owing to the utilization of technique scheme, the utility model compared with prior art has advantage: when elevator moved, car and sedan-chair frame were made vertical displacement movement along guide rail; Then roller is done correspondingly to roll along guide rail, and the running velocity of car can reflect through the rolling speed or the rotating speed of roller, in this elevator speed governor; In case elevator operation hypervelocity takes place, and then mutually deserved, the rolling of roller also can exceed the speed limit; Then speed limit triggers the wheel rotation that can be triggered, and through drg stop car or sedan-chair frame, this elevator speed governor avoids the use of speed limiter wire rope and steel rope swelling device; Saved hoistway space; Improve the hoistway degree of utilization, and step down on car or the sedan-chair frame and can carry out installation and maintenance this speed-limit device, more convenient.
Description of drawings
accompanying drawing 1 is the scheme drawing of the utility model.
The specific embodiment
The structure of the utility model is further set forth in
below in conjunction with accompanying drawing.
referring to shown in Figure 1, elevator speed governor comprises that roller 1, speed limit trigger wheel 2, drg 3, lifting rod 4; The wheel shaft of roller 1 is horizontally set on elevator car frame or the car, and roller 1 can roll on wheel shaft, and roller 1 is rollably conflicted with cage guide 5 mutually; When elevator moves like this; Car and sedan-chair frame are being made vertical displacement movement along guide rail 5, and then roller 1 is done correspondingly to roll along guide rail 5, and the running velocity of car can reflect through the rolling speed or the rotating speed of roller 1; Speed limit triggers wheel 2 and is contained on the wheel shaft; Be that speed limit triggers wheel 2 and roller 1 coaxial setting, when the rotating speed of roller 1 surpassed setting value, speed limit triggering wheel 2 can be driven together by roller 1 and rotate; Here setting value refers to such an extent that be the critical value that is converted into the rotating speed of roller 1 according to the critical speed that the elevator that GB adopts moves, and the critical speed of elevator operation for example adopts 115% of command speed.When the rotating speed of roller 1 surpassed setting value, under action of centrifugal force, speed limit triggered wheel 2 and can rotate with roller 1; The speed limit of rotating triggers wheel 2 can 3 actions of drive brake devices, drg 3 with elevator car frame or car stop on cage guide 5, in Fig. 1; Speed limit triggers and rotates an end that is provided with lifting rod 4 on the wheel 2; The other end of this lifting rod 4 rotates and is arranged on the drg 3, and this drg 3 adopts elevator safety gear, and speed limit triggers and can lift lifting rod 4 after wheel 2 rotates like this; Lifting rod 4 can lift the safety tongs action, realizes stop elevator sedan-chair frame.In this elevator speed governor, in case elevator operation hypervelocity takes place, then mutually deserved, the rolling of roller 1 also can exceed the speed limit, and then speed limit triggers wheel 2 rotation that can be triggered, through drg 3 stop cars.This elevator speed governor avoids the use of speed limiter wire rope and steel rope swelling device, has saved hoistway space, improves the hoistway degree of utilization, and steps down on car or the sedan-chair frame and can carry out installation and maintenance to this speed-limit device, and is more convenient.
in Fig. 1, speed limit triggers wheel 2 and adopts two-way centrifugal ratchet, and when the rotating speed of roller 1 surpassed setting value, under action of centrifugal force, ratchet can insert in the ratchet slot of ratchet, is being with speed limit to trigger wheel 2 through roller 1 and is rotating together.
Skid when preventing that roller 1 from rolling on guide rail 5
; Elevator car frame or car are provided with tightening device; This tightening device comprises the elastic component (not shown); Elastic component is arranged between the wheel shaft and sedan-chair frame or car of roller, and this elastic component can provide the roller shaft elastic-restoring force, and feasible roller 1 is stably conflicted rolled on guide rail 5.This tensioning device structure is simple, not extra basically shaft space occupation.
