Abstract
The utility model discloses a protector with a guide pulley capable of being used on an elevator. With improvement of the running speed of the elevator, a throwing block can move in a guide groove in the guide pulley, and is subjected to centrifugal force effect and far away from the center of the guide pulley, thus an electrical safety switch is triggered, a push rod stretches out and pushes detents, the detents clamp a ratchet wheel, and the ratchet wheel and the guide pulley stop rotating. With further improvement of the running speed of the elevator, a speed measurement switch acts, a connecting rod is lifted and pulled through an elevator safety mechanism by a controller, thus a hoisting rope is clamped through a rope gripper, a lift car is stopped, and overspeed protection is achieved. Compared with an existing speed limiter, the protector with the guide pulley capable of being used on the elevator is simple in structure and small in size, saves wellhole space, improves the utilization rate of the wellhole space, and meanwhile saves cost, and facilitates installation and maintenance.
Description
Technical field
The utility model relates to the fender guard that utilizes track adjusting wheel on a kind of elevator.
Background technology
In prior art, the overspeed protection of elevator realizes by velocity limiter.The structure of velocity limiter is very complicated, and volume is very large, causes the hoistway degree of utilization low.
Summary of the invention
The purpose of this utility model is to provide the overspeed protection device that utilizes track adjusting wheel to realize that can substitute velocity limiter on a kind of elevator.
for achieving the above object, the technical solution adopted in the utility model is: the fender guard that utilizes track adjusting wheel on a kind of elevator, the hoist ropes of elevator is walked around described track adjusting wheel downwards, the described fender guard of track adjusting wheel that utilizes comprises and the co-axially fixed ratchet of described track adjusting wheel, be opened in the guide groove on the radial surface of described track adjusting wheel, thereby being arranged in described guide groove to be subjected to centrifugal action to make the piece that gets rid of of centrifugal motion in described guide groove when described track adjusting wheel rotation, rotation is arranged on the described ratchet of forbidding this ratchet rotation in the teeth groove that can insert described ratchet on piece that gets rid of, thereby the piece that gets rid of that has the push rod that can stretch out and can be made centrifugal motion touches the electric safety switch that makes described push rod stretch out to promote in the teeth groove that described ratchet inserts described ratchet, can measure the speed measurement switch of the kinematic velocity of described hoist ropes, thereby can clamp the wire holder of described hoist ropes stop elevator car, thereby the hoist ropes kinematic velocity value that can measure at described speed measurement switch is controlled elevator safety mechanism during greater than setting value and is lifted connecting rod and make described wire holder clamp the controller of described hoist ropes.
Described track adjusting wheel is car sheave or counterweight sheave.
Utilization due to technique scheme; the utility model compared with prior art has following advantages: the fender guard that this utilizes track adjusting wheel is set; along with the raising of elevator speed; getting rid of piece can move in the guide groove on track adjusting wheel; be subjected to centrifugal action away from the track adjusting wheel center, thereby trigger electric safety switch, make push rod stretch out the promotion ratchet; ratchet blocks ratchet, and ratchet and track adjusting wheel are stopped the rotation.Along with the further raising of elevator speed, the speed measurement switch effect make elevator safety mechanism lift connecting rod by controller, thereby wire holder clamps hoist ropes, and the stop car is realized overspeed protection.With respect to existing velocity limiter, this utilizes the fender guard of track adjusting wheel simple in structure, and volume is little, has saved hoistway space, has improved the degree of utilization of hoistway space, also saves cost simultaneously, is convenient to installation and maintenance.
Description of drawings
Accompanying drawing 1 is schematic diagram of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Figure 1, the hoist ropes 10 of elevator is walked around track adjusting wheel 2 downwards, and track adjusting wheel 2 is car sheave or counterweight sheave.Utilize the fender guard of track adjusting wheel on elevator, thereby comprise with the co-axially fixed ratchet 6 of track adjusting wheel 2, be opened in guide groove on the radial surface of track adjusting wheel 2, be arranged on getting rid of piece 5, rotate and be arranged on ratchet 1, the electric safety switch 4 with the push rod 7 that can stretch out, the speed measurement switch 3 that can measure the kinematic velocity of hoist ropes 10 that gets rid of on piece 5, wire holder 8, the controller that can clamp hoist ropes 10 stop elevator cars in guide groove.when elevator normally moves, hoist ropes 10 can drive track adjusting wheel 2 and do corresponding rotation, raising along with the running velocity of elevator, correspondingly, the rotative speed of track adjusting wheel 2 also can improve, get rid of like this piece 5 and can make centrifugal motion under centrifugal action in guide groove, center away from track adjusting wheel 2, piece 5 meetings of getting rid of of making centrifugal motion trigger electric safety switch 4, the push rod 7 of electric safety switch 4 can stretch out like this, promote ratchet 1, make ratchet 1 insert in the teeth groove of ratchet 6, forbid this ratchet 6 rotations, because track adjusting wheel 2 is co-axially fixed with ratchet 6, track adjusting wheel 2 rotation that also can be under an embargo, if this moment, elevator still moved, hoist ropes 10 can skid on track adjusting wheel 2.Further raising along with elevator speed; when the hoist ropes 10 kinematic velocity values that measure of speed measurement switch 3 were greater than setting value, controller can be controlled elevator safety mechanism and lift connecting rod 9, thereby makes wire holder 8 clamp hoist ropes; stop is lived car, has realized the overspeed protection of elevator operation.
This utilizes the fender guard of track adjusting wheel, can substitute existing velocity limiter and carry out elevator overspeed protecting, and this utilizes the fender guard of track adjusting wheel simple in structure; compactness, volume is little, has saved hoistway space; improve the degree of utilization of hoistway space, also saved cost simultaneously, be convenient to installation and maintenance.
Claims (2)
1. utilize the fender guard of track adjusting wheel on an elevator, the hoist ropes of elevator is walked around described track adjusting wheel downwards, it is characterized in that: the described fender guard of track adjusting wheel that utilizes comprises and the co-axially fixed ratchet of described track adjusting wheel, be opened in the guide groove on the radial surface of described track adjusting wheel, thereby being arranged in described guide groove to be subjected to centrifugal action to make the piece that gets rid of of centrifugal motion in described guide groove when described track adjusting wheel rotation, rotation is arranged on the described ratchet of forbidding this ratchet rotation in the teeth groove that can insert described ratchet on piece that gets rid of, thereby the piece that gets rid of that has the push rod that can stretch out and can be made centrifugal motion touches the electric safety switch that makes described push rod stretch out to promote in the teeth groove that described ratchet inserts described ratchet, can measure the speed measurement switch of the kinematic velocity of described hoist ropes, thereby can clamp the wire holder of described hoist ropes stop elevator car, thereby the hoist ropes kinematic velocity value that can measure at described speed measurement switch is controlled elevator safety mechanism during greater than setting value and is lifted connecting rod and make described wire holder clamp the controller of described hoist ropes.
2. utilize the fender guard of track adjusting wheel on elevator according to claim 1, it is characterized in that: described track adjusting wheel is car sheave or counterweight sheave.
