On pedestal 23, be installed with and reply with lever 42.Replying with lever 42, is that the center can be swung with the axle 43 parallel with sheave shaft 22.On pawl 29, be provided with by replying and swing the rotation projection 44 freely that is urged with lever 42.Use between the lever 42 at pedestal 23 and answer, be provided with to make and reply with the return spring 45 of lever 42 to the direction application of force of leaving projection 44.
On axle 43, be installed with by operating from the outside, being the center and replying the effect lever 76 that rotates integratedly with lever 42 with axle 43.Answer auxiliary mechanism in this example has and replys with lever 42, projection 44, return spring 45 and effect lever 76.This replys auxiliary mechanism, by effect lever 76 being operated a part of mechanism of making governor body 9, being pawl 29 and tripping lever 72 from by the replying state of the operating state that carries out overspeed detection before action.That is, replying auxiliary mechanism assists the answer action of governor body 9.
Again, the elevator used governor in this example has governor body 9, replys auxiliary mechanism and control member 75.
Fig. 3 is the front view of the main portion of presentation graphs 2, and Fig. 4 is expression is rocked to the answer of Fig. 3 the state of replying the position with lever 42 a front view.In Fig. 3, answer is in common position with lever 42, and leaves projection 44.When the state from Fig. 3 makes control member 75 upward during displacement, effect lever 76 is operated member 75 pushings and rotates, reply with lever 42 also with return spring 45 antagonism be rocked to the answer position.Thus, projection 44 is replied with lever 42 pushings, and pawl 29 rotates with extension spring 74 antagonism ground clockwise directions in figure and engages with tripping lever 72.
Then, action is described.When the rising or falling speed of car 4 reaches the 1st hypervelocity (be generally command speed about 1.3 times), utilize the flyball 25 that produces by centnifugal force rotation, make start pawl 37 and car stop and making switch lever 28a rotation with the switch lever 28a butt of switch 28.Thus, switch 28 actions, the power supply of cut-out actuating device 2 utilizes the brake equipment of actuating device 2 that car is stopped.
Again, in for example main rope 3 post-rift occasions, even actuating device 2 stops, car 4 also can not stop and continuing to descend, when the descending speed of car 4 reached the 2nd hypervelocity (be generally command speed about 1.4 times), flyball 25 further rotated, with this, the amount of spin of tripping lever 72 also increases, and makes the disengagement that engages of tripping lever 72 and pawl 29.Thus, pawl 29 utilizes the spring force of extension spring 74 to rotate and engages with the tooth of ratchet 30.And ratchet 30 rotates slightly with rope sheave 21 anticlockwise direction in Fig. 2.
Utilize the rotation of this ratchet 30, make support arm 31 anticlockwise motion in Fig. 2, in brake shoe 32 and governor rope 11 butts, utilize rope to catch spring 36 that brake shoe 32 is pushed to governor rope 11, governor rope 11 is braked.When the circulation of governor rope 11 stops, continuing to descend by car 4, and lever 12 is operated, making very, shutdown feature 7 moves.
Then, the answer operation after the action of very shutdown feature 7 and governor body 9 is described.In replying operation, at first, car 4 is risen a little, the unusual braking mode of 7 pairs of car guide rails 6 of shutdown feature is removed.Then, when car 4 is further risen, by governor rope 11 rope sheave 21 is rotated to the clockwise direction of Fig. 2, make the disengagement that engages of pawl 29 and ratchet 30, ratchet 30 also returns original position to the clockwise direction rotation of figure.Thus, support arm 31 returns original position, and brake shoe 32 leaves from governor rope 11.
Then, make car 4 from the superiors take advantage of the Room 13 to rise to can to take advantage of behind the position on the top board of car 4, the door 14 of taking advantage of the Room of taking advantage of the Room 13 of the superiors is opened, worker is taken advantage of on car 4.And, from car 4, hand is stretched to governor body 9, engage with tripping lever 72 by making pawl 29, finish to reply operation.
Like this, worker just can make pawl 29 engage with tripping lever 72 with hand if take advantage of on car 4, does not need to use answer auxiliary mechanism.
On the other hand, if governor body 9 carry out the 2nd when action hypervelocity car 4 the position the superiors take advantage of near the Room 13, open from this position take advantage of the Room 14 and do not take advantage of occasion on the top board of car 4, car 4 is risen again, utilize 75 pairs of effects of control member lever 76 to push.Thus, swing to the clockwise direction of Fig. 2～Fig. 4 with lever 42 and return spring 45 antagonism ground in governor body 9 sides, answer, projection 44 is replied with lever 42 pushings.And pawl 29 rotates with extension spring 73 antagonism ground clockwise directions in Fig. 2～Fig. 4, engages with tripping lever 72.
Again, the occasion replying with the lever 42 position relation not relative with projection 44 temporarily rises car 4 by original state, make rope sheave 21 to right-hand revolution.Thus, control member 75 continues butts with effect lever 76, the projection 44 of rotate integratedly with rope sheave 21, with the answer that is positioned at the answer position with lever 42 butts be urged.
By operating like this, car 4 is positioned near taking advantage of the Room 13 of the superiors, even open and do not take advantage of occasion on car 4 top boards at the door 14 that will take advantage of the Room from this position, also can pawl 29 be engaged with tripping lever 72 by from taking advantage of the remote servicing of the Room 13 sides.
Therefore, even in hoist trunk 1, dispose the occasion of governor body 9, need not be provided with peristome from usefulness to governor body 9 that adjust on the wall of the Room taking advantage of yet, can improve the operation of replying operation easily from carrying out answer operation at a distance to governor body 9.
Do not need from governor body 9 to prevent the reduction of the degree of freedom of the facility location in the hoist trunk 1 to taking advantage of the Room 13 to carry out the distribution of steel wire that remote servicing uses etc. again, yet.
Again, locate to make the occasion after very shutdown feature 7 moves below than the superiors, worker does not need to take advantage of on car 4 yet, can use control member 75 to reply operation.But, because if car 4 is moved to the top than the stop position of the superiors, for example, take time in order to make safety device releasing etc., so take advantage of the method on car 4 fairly simplelyly and morely to be used as mentioned above.
Again, in above-mentioned example, control member 75 is fixed on the car 4, but control member can be moved up and down by relative car 4.This occasion can not make car 4 more be moved upward than the stop position of the superiors, can use control member to reply operation.Again, make the occasion that control member is moved up and down, can utilize the M/C in the cage to move up and down or also can utilize the propulsive effort of electrical motor etc. to move up and down.
Again, in above-mentioned example, represented so-called machine room-less elevator, and if governor is configured in the lift appliance on the top in the hoist trunk, the present invention also can be applicable to the lift appliance of Machine Room.
