Description
Technical field
The utility model relates to the safety device that a kind of elevator works when the irregular operating state, specifically relate to a kind ofly prevent elevator hoist or the elevator governor of hypervelocity when descending.
Background technology
When the running velocity of elevator hoist or decline surpasses command speed; or during the traction steel wire fracture of rope of elevator; just need safety device in time system to be protected; to prevent unexpected the generation; existing velocity limiter normally utilizes rope sheave to rotate the centnifugal force that produces; by outage; mechanical brake device makes on its guide rail that rests on elevator the elevator brake that hypervelocity descends; 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.
The utility model content
The purpose of this utility model provides the velocity limiter that a kind of mechanical brake device response time elevator short, that hypervelocity is descended carries out electric signal and mechanical speed limit, elevator that hypervelocity is risen carries out the electric signal speed limit.
Elevator governor of the present utility model, comprise the rope sheave that is wound with steel rope, rope sheave is installed on the sheave shaft, sheave shaft is installed in rotation on the support, support is provided with snap switch, be positioned at described rope sheave left side on the described sheave shaft brake disc is installed, brake disc is provided with teeth groove and plain hook, the centrifugal block for clutch use device is installed on the rope sheave, the centrifugal block for clutch use device comprises that two of being installed in symmetrically on the rope sheave gusset get rid of piece, getting rid of piece is provided with switch and beats bar and moving tooth, switch is made bar and is matched with described snap switch, moving tooth matches with the teeth groove that described brake disc is provided with, slipper matches with rope clamping block on being fixed on support, be overlapped with curved part on the described plain hook, the other end of curved part links to each other with slipper, slipper is installed on the pitman shaft, pitman shaft is installed on the axle, axle is installed in rotation on the support, gap between described steel wire penetrating slipper and the rope clamping block, the two ends of described sheave shaft are installed in respectively on the support, and an end of described axle is provided with and can makes the slipper that is fixed on the pitman shaft quicken the torsion spring of whereabouts.
Elevator governor of the present utility model, an end of wherein said torsion spring adopts and is bolted on the axle, and the other end is fixed on the support.
The advantage of elevator governor of the present utility model is: it is provided with and can makes the slipper that is fixed on the pitman shaft quicken the torsion spring of whereabouts, has that mechanical brake device response time elevator short, that hypervelocity is descended carries out electric signal and mechanical speed limit, elevator that hypervelocity is risen carries out the electric signal speed limit.
Below in conjunction with accompanying drawing elevator governor of the present utility model is described further.
