Abstract
The invention relates to an elevator speed limiter. A steel wire rope is arranged on the outer side of a rope wheel, a fixed ratchet wheel disc is arranged on the inner side of the rope wheel, a fly arm I and a fly arm II are arranged on the inner side of the fixed ratchet wheel disc, a spindle is arranged in the center of the fixed ratchet wheel disc, anchor pins are arranged in the middle of the fly arm I and the middle of the fly arm II respectively, the fly arm I and the fly arm II are connected through a connecting rod, an elastic device is arranged at one end of the fly arm II, a wear-resistant material layer is arranged on the surface of each pawl of the fixed ratchet wheel disc, heat radiation holes are formed in a disc body of the fixed ratchet wheel disc, crescent wear-resistant layers are arranged on a nail groove of the fly arm I and a nail groove of the fly arm II, and rectangular reinforcement blocks are arranged on the pawl arm back faces of the fly arm I and the fly arm II. The elevator speed limiter is simple in structure and reasonable in design, the heat radiation holes and the wear-resistant material layers are arranged, in the work process of the speed limiter, the fly arms and the pawls can be effectively protected, heat radiation is accelerated, and the work effect of the speed limiter is guaranteed.
Description
Technical field
The present invention relates to elevator, relate in particular to a kind of elevator governor.
Background technology
Elevator, a kind ofly take the vertical conveyor that electrical motor is power, and case shape gondola is housed, and for tier building, takes advantage of people or carrying goods.It has a car, operates between the rigid guideway that the vertical or leaning angle of at least two row is less than 15 °.Car size and version are convenient to passenger's discrepancy or handling goods.Wherein when elevator is in operational process during suddenly power-off, substantially at present adopt velocity limiter and coordinating of safety tongs to realize to brake.Now widely used elevator speed-limiting protective device is all to drive brake equipment safety tongs to move by velocity limiter, and deceleration of elevator is stopped.Velocity limiter comprises rope sheave, on rope sheave around hanging with the steel rope being connected with lift car, thereby make the speed rotation that governor sheave can be corresponding with the speed with car.When the rotative speed of governor sheave surpasses certain speed, the centnifugal force that centrifugal block for clutch use on governor sheave produces by means of rope sheave rotation rotates, drive fly jib and ratchet action on rope sheave, governor sheave stops operating, thereby utilize the wire rope pulling safety tongs action of tensioning to make elevator stop motion, in braking procedure, friction force between fly jib and ratchet is large, therefore the friction between will alleviating, extend the life-span of velocity limiter, the heat producing in braking procedure also can affect the work of velocity limiter simultaneously.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of elevator governor.
The present invention is achieved through the following technical solutions:
A kind of elevator governor, comprise rope sheave, fixed ratchet wheel dish, fly jib I, fly jib II, steel rope, main shaft, the outside of described rope sheave is provided with steel rope, inner side is provided with fixed ratchet wheel dish, described fixed ratchet wheel dish inner side is provided with fly jib I, fly jib II, described main shaft is arranged on fixed ratchet wheel Pan center, described fly jib I, fly jib II is reverse symmetry and arranges, fly jib I, fly jib II middle part is equipped with anchor, fly jib I, between fly jib II, by connecting rod, be connected, one end of described fly jib II is provided with springing, each detent face on described fixed ratchet wheel dish is provided with wear-resistant material layer, the disk body of fixed ratchet wheel dish is provided with louvre, described fly jib I, in the nail groove place of fly jib II, there is crescent wearing layer, fly jib I, the pawl arm back side of fly jib II is provided with rectangle boss.
As preferably, described louvre is uniform layout on the disk body of fixed ratchet wheel dish.
As preferably, between described rectangle boss and fly jib I, fly jib II, be and be fixedly connected with.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is simple in structure, reasonable in design, by louvre is set, can accelerate the heat that velocity limiter produces between fly jib and ratchet in braking procedure, thereby guaranteed the working effect of velocity limiter; By wear-resistant material layer is set, in the working process of velocity limiter, actv. has been protected fly jib and ratchet, has extended the service life of velocity limiter; By boss is set, can effectively raises the intensity of fly jib, thereby improve the safety of elevator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
