Abstract
The utility model relates to an elevator speed limiting device which comprises an engine base that is provided with a rope wheel shaft and a shaft that can rotate, and an instant-on switch; the rope wheel shaft is provided with a rope wheel wound with a rope; the rope wheel is provided with a centrifugal block throwing device; one side of the rope wheel is provided with a brake disc; the shaft is provided with a connecting rod shaft which is provided with a brake block that is matched with a rope clamping block fixed on the engine base; and one end of the shaft is provided with a torsion spring used for controlling the brake block to fall down in an accelerating way. As the torsion spring is used for controlling the brake block so as to limit the speed of an elevator by an electrical signal or in a mechanical way, the device has the advantages of short response time and timely brake, and can effectively prevent the occurrence of squatting in a pit and rushing to the top of an elevator car.
Description
[technical field]
The utility model belongs to the lift facility technical field, relate to a kind of when overspeed appears in elevator, can make the elevator speed governor of elevator emergency brake.
[background technology]
For preventing that the elevator overspeed operation from having an accident, speed-limit device all is installed, on elevator so that can emergency braking when hypervelocity appears in elevator.Existing elevator speed governor normally utilizes rope sheave to rotate the centnifugal force that is produced, by outage, mechanical braking the elevator brake that hypervelocity descends is made on its guide rail that rests on elevator, but because the moving rope clamping block in the mechanical brake device is to rely on the motion braking that action of gravity produces, its folder rope speed is relatively slow, cause the mechanical brake device response time longer, stayed potential safety hazard for the normal operation of equipment.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides the elevator speed governor that a kind of response time is short, brake in time and have the bi-directional braking function.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of elevator speed governor, comprise support, the sheave shaft and the axle that can rotate is installed and snap switch is housed at support, the rope sheave that twines the silk rope is installed on sheave shaft, the centrifugal block for clutch use device is installed on rope sheave, brake disc is installed in a side of rope sheave; Pitman shaft is installed on axle, slipper is installed on pitman shaft, slipper matches with rope clamping block on being fixed on support, is provided with the control brake piece at an end of axle and quickens the torsion spring of whereabouts.
Described brake disc is provided with teeth groove and plain hook, is overlapped with curved part on the plain hook, and the other end of curved part links to each other with slipper.
Described centrifugal block for clutch use device has two of being installed in symmetrically on the rope sheave gusset to get rid of piece, is provided with switch on the piece and beats bar and moving tooth getting rid of, and switch is made bar and matched with snap switch, and the teeth groove that is provided with on moving tooth and the brake disc matches.
Described silk rope passes the gap between slipper and the rope clamping block.
The two ends of described sheave shaft are installed on the support respectively.
One end of described torsion spring is by being bolted on the axle, and its other end is fixed on the support.
The beneficial effects of the utility model are: adopt torsion spring control brake piece, elevator is carried out electric signal or mechanical speed limit, have the response time weak point, brake advantage timely, can prevent effectively that the latrine pit of lift car and the accident of rushing to summit from taking place.
