Fig. 2 is the longitudinal section that the velocity limiter 12 of Fig. 1 is shown.In addition, Fig. 3 is the longitudinal section of state of telescopic boom elongation that the velocity limiter 12 of Fig. 2 is shown.In addition, Fig. 4 is the front view that the velocity limiter 12 of Fig. 2 is shown.In the drawings, velocity limiter 12 is by supporting mass 19 supportings.Velocity limiter main body 14 has: rope sheave linkage 20, and it is according to the rotative speed and governor sheave 15 interlocks of governor sheave 15; Hypervelocity switch for over speed detection 21, it is by being exported the danger signal that the running that makes elevator stops by rope sheave linkage 20 operation; And grasping device 22 (Fig. 4), it is by being controlled overspeed governor 16 by 20 operations of rope sheave linkage.
As shown in Figures 2 and 3, the sheave shaft 23 of governor sheave 15 is supported on supporting mass 19 through bearing 24 by on even keel.Be fixed with driving finishing bevel gear cuter 25 in the end of sheave shaft 23.
Rope sheave linkage 20 has: driven shaft (S. A.) 26, and it disposes along vertical direction; Driven wheel of differential 27, it is fixed on the bottom of driven shaft 26, and meshes with driving finishing bevel gear cuter 25; Displacement body 28, it is located at driven shaft 26, and can be with respect to driven shaft 26 in the direction displacement along driven shaft 26; Centrifugal shift assembly 29, it makes 28 displacements of displacement body corresponding to the rotation of driven shaft 26; And displacement setting device 30, it can be set centrifugal shift assembly 29 for: it is different when reversing with driven shaft 26 when just changeing that the pass between the shift amount of the rotative speed that makes driven shaft 26 and displacement body 28 ties up to driven shaft 26.
Driven shaft 26 is supported in supporting mass 19 via bearing 31.The rotation of sheave shaft 23 is passed to driven shaft 26 via driving finishing bevel gear cuter 25 and driven wheel of differential 27.Therefore, driven shaft 26 rotates corresponding to the rotation of governor sheave 15.That is, driven shaft 26 is just changeing when governor sheave 15 is just changeing, driven shaft 26 counter-rotatings when governor sheave 15 counter-rotatings.
Centrifugal shift assembly 29 is located at the top of driven shaft 26.In addition, centrifugal shift assembly 29 rotates integratedly with driven shaft 26.And centrifugal shift assembly 29 has: a pair of ball (fly-ball) (Governor weight) 32 that gets rid of, and they are center revolution along with the rotation of driven shaft 26 with driven shaft 26; A pair of telescopic boom 33, they will respectively get rid of ball 32 respectively and link to each other with the upper end of driven shaft 26, and this a pair of telescopic boom 33 can rotate with respect to driven shaft 26; Slide cartridge 34, driven shaft 26 passes this slide cartridge 34 in the mode that can slide; Link rod part material 35, it makes each telescopic boom 33 and slide cartridge 34 interlocks; And balance spring 36, it is to slide cartridge 34 application of force downwards.
Respectively get rid of ball 32 by being that center revolution is subjected to and the cooresponding centnifugal force of the rotative speed of driven shaft 26 with driven shaft 26.
Corresponding to getting rid of the centnifugal force that ball 32 is subjected to, telescopic boom 33 is shifted by rotation with respect to driven shaft 26.Corresponding to the displacement of each telescopic boom 33 with respect to driven shaft 26, slide cartridge 34 is in the direction displacement along driven shaft 26.That is, when the rotative speed of driven shaft 26 increased, telescopic boom 33 was shifted to respectively getting rid of ball 32 directions separated from one another, and slide cartridge 34 overcomes the application force of balance spring 36 and is shifted upward.In addition, when the rotative speed of driven shaft 26 reduced, telescopic boom 33 was shifted to respectively getting rid of ball 32 directions close to each other, and slide cartridge 34 is displacement downwards by the application force of balance spring 36.
Each telescopic boom 33 has: arm main body 37, and it is mounted to and can rotates with respect to driven shaft 26; And actuator 38, it is located at arm main body 37, and makes the length variations of telescopic boom 33.
Actuator 38 has: can be with respect to the plunger (plunger) 39 of arm main body 37 displacements; And the magnet coil 40 that plunger 39 is shifted with respect to arm main body 37.
Get rid of ball 32 and be installed on plunger 39.Plunger 39 can be at the extended position that leaves arm main body 37 (Fig. 3) with than extended position displacement between the near punctured position (Fig. 2) of arm main body 37.Between extended position and punctured position, be shifted the length variations of telescopic boom 33 by plunger 39.Plunger 39 is by energising is displaced to extended position to magnet coil 40, and is displaced to punctured position by the application force of not shown force body in the time of the energising that stops magnet coil 40.
Displacement body 28 can be with slide cartridge 34 displacements.Thus, displacement body 28 is shifted in the direction along driven shaft 26 accordingly with the rotative speed of governor sheave 15.In addition, displacement body 28 can rotate freely with respect to slide cartridge 34 and driven shaft 26.Therefore, even slide cartridge 34 and driven shaft 26 rotations, displacement body 28 still keeps non-rotary state.And displacement body 28 has: driven tube 41, and driven shaft 26 passes this driven tube 41 in the mode that can slide; And from the outstanding operating portion 42 of the outer peripheral face of driven tube 41.
Displacement setting device 30 makes each telescopic boom 33 flexible, thereby the length that makes each telescopic boom 33 is different length when driven shaft 26 is just changeing and when reversing.Promptly, displacement setting device 30 is by making the revolution radius that respectively gets rid of ball 32 different when the just commentaries on classics of driven shaft 26 and during counter-rotating, and it is different when reversing with driven shaft 26 when just changeing to make pass between the shift amount of rotative speed and the body 28 that is shifted of driven shaft 26 tie up to driven shaft 26.
In this example, displacement setting device 30 when rising (, car 8) when driven shaft 26 is just changeing shortens the length of each telescopic boom 33, and when driven shaft 26 counter-rotatings (, when car 8 descends) and make the length of each telescopic boom 33 just change duration than driven shaft 26.
Displacement setting device 30 has: electrical generator 43, and its rotation by driven shaft 26 is generated electricity; And rectifying device 44, in its electric power that only will send by electrical generator 43, when driven shaft 26 is just changeing and the electric power of the either party during counter-rotating be delivered to magnet coil 40.
Electrical generator 43 is located at the upper end of driven shaft 26.In addition, electrical generator 43 is dynamo generators.And electrical generator 43 has: electrical generator anchor shaft 45, and it comprises permanent magnet; And electrical generator main body 46, it comprises the generating coil, and surrounds electrical generator anchor shaft 45.Electrical generator is installed on supporting mass 19 with anchor shaft 45 by fabricated section 47.Electrical generator main body 46 is rotated integratedly with driven shaft 26.When electrical generator main body 46 and driven shaft 26 rotate integratedly, in generating coil midstream excess current.Flowing through generating changes with the sense of current of the coil hand of rotation according to driven shaft 26.That is, electrical generator 43 produces positive current when driven shaft 26 is just changeing, and produces negative current when driven shaft 26 counter-rotatings.
Rectifying device 44 is electrically connected with electrical generator main body 46 and magnet coil 40 respectively by lead 48,49.In addition, rectifying device 44 only in the future the either party of the reversal of spontaneous motor 43 be delivered to magnet coil 40.When only driven shaft 26 just being changeed thus, and a certain side's in when counter-rotating electric power be delivered to magnet coil 40 from rectifying device 44.
In this example, in the reversal from electrical generator 43, only negative current (that is the electric current when, only car 8 descends) is delivered to magnet coil 40 from rectifying device 44.Positive current is cut off by rectifying device 44, can not arrive magnet coil 40.Therefore, the length of each telescopic boom 33 is elongated when car 8 descends, and the length of each telescopic boom 33 shortened when car 8 rose.
Hypervelocity switch for over speed detection 21 is disposed at the radial outside of driven tube 41.In addition, hypervelocity switch for over speed detection 21 has: switch main body 50, and it is fixed in supporting mass 19; And switch lever 51, it is located at switch main body 50, and side-prominent to displacement body 28.Become can operating switch bar 51 with respect to the displacement of hypervelocity switch for over speed detection 21 by displacement body 28 for operating portion 42.Be operated portion 42 operation by switch lever 51, hypervelocity switch for over speed detection 21 detects speed unusual of car 8.That is, whether hypervelocity switch for over speed detection 21 has based on whether detecting the speed that displacement body 28 detects car 8 unusually.Speed by detecting car 8 by hypervelocity switch for over speed detection 21 unusual, the danger signal that the running of elevator is stopped from switch main body 50 outputs.
When the length of each telescopic boom 33 is elongated, increase owing to respectively get rid of the revolution radius of ball 32, to compare when therefore shortening with the length of each telescopic boom 33, the shift amount of displacement body 28 increases.Therefore, when the length of each telescopic boom 33 is longer, compare more in short-term with the length of each telescopic boom 33, in the low stage of the rotative speed of driven shaft 26, displacement body 28 will reach the position that switch lever 51 is operated.That is, to detect the rotative speed (first set hypervelocity speed) of unusual driven shaft 26 of the speed of car 8 are such values to hypervelocity switch for over speed detection 21: this rotative speed when the length of each telescopic boom 33 is longer (when car 8 descends) than the length of each telescopic boom 33 more in short-term (during car 8 risings) low.
Control setup 6 is based on the running of controlling elevator from the information of hypervelocity switch for over speed detection 21.In this example, control setup 6 has taken place to stop the control of the running of elevator unusually by the speed that the danger signal of receiving from hypervelocity switch for over speed detection 21 is judged to be car 8.
As shown in Figure 4, grasping device 22 is configured in the below of governor sheave 15.In addition, grasping device 22 has: fixedly boots 52, and it is fixed in supporting mass 19; Movable boots 53, it can be shifted controlling between position and the releasing position, described holding position be and fixedly control the position of overspeed governor 16 between the boots 52, described releasing position is than controlling the position away from the fixing position of boots 52; Displacement press device 54, it is created in and is displaced to movable boots 53 of controlling the position and the hold of fixedly controlling overspeed governor 16 between the boots 52; And holding device 55, it remains on the releasing position with movable boots 53 usually the time, and the rotative speed by driven shaft 26 reaches and sets hypervelocity fast second than first and set hypervelocity speed and remove maintenance to movable boots 53.
Displacement press device 54 has: the boots that can stretch telescopic boom 56, and it is connected between the installation portion and movable boots 53 of being located at supporting mass 19; And press pressing spring (force body) 57, it is located at boots with telescopic boom 56, and to movable boots 53 to the direction application of force away from the installation portion of supporting mass 19.
Boots are connected with movable boots 53 with the installation portion of supporting mass 19 respectively in the mode that can rotate with telescopic boom 56.Rotate with respect to the installation portion of supporting mass 19 with telescopic boom 56 by boots, movable boots 53 are shifted controlling between position and the releasing position.Control the position by movable boots 53 are displaced to, boots are pushed and are shunk with telescopic boom 56 boots 52 that are fixed.In addition, be displaced to the releasing position by making movable boots 53, boots are subjected to extending by the application force of pressing spring 57 with telescopic boom 56.
Press pressing spring 57 in the installation portion of supporting mass 19 and movably contraction between the boots 53.In addition, be to have passed the coil spring of boots in inside by pressing spring 57 with telescopic boom 56.Use the contraction and further increase of telescopic boom 56 by boots by the application force of pressing pressing spring 57 generations.
Control the position by movable boots 53 are displaced to, the application force of pressing pressing spring 57 increases, thereby has produced the hold based on displacement press device 54.
Holding device 55 has: clamping rpole 58, and it can break away between the releasing position that engages at the clamped position that engages with movable boots 53 with movable boots 53 and is shifted; Remove with spring (force body) 59, its to clamping rpole 58 to being displaced to the direction application of force of removing the position; And press section material 60, the application force that its opposing is removed with spring 59 remains in clamped position with clamping rpole 58.
Clamping rpole 58 is by being that rotate at the center with the bar axle 61 of being located at supporting mass 19, and at clamped position with remove between the position and be shifted.Remove and be connected between clamping rpole 58 and the supporting mass 19 with spring 59.
Press section material 60 can be that rotate at the center with the bolster 62 of being located at supporting mass 19.In addition, press section material 60 links via connecting rod 63 and displacement body 28.Thus, press section material 60 be center rotation with the displacement of displacement body 28 with bolster 62.
Connecting rod 63 is connected respectively with press section material 60 with displacement body 28 in the mode that can rotate.In addition, connecting rod 63 displacement upward by the rising of the rotative speed of driven shaft 26.
Clamping rpole 58 is maintained at clamped position by press section material 60 usually the time.By connecting rod 63 displacement upward, press section material 60 rotates to the direction that the maintenance that makes 60 pairs of clamping rpoles 58 of press section material is thrown off.Set hypervelocity speed by the rotative speed of driven shaft 26 above first and reach the second setting hypervelocity speed, the maintenance of 60 pairs of clamping rpoles 58 of press section material is thrown off.
When the maintenance of 60 pairs of clamping rpoles 58 of press section material is thrown off, clamping rpole 58 is by removing with the application force of spring 59 from clamped position to removing displacement, the disengagement that engages of movable boots 53 and clamping rpole 58.When of the engage disengagement of movable boots 53 with clamping rpole 58, movable boots 53 because of deadweight to controlling displacement, thereby at fixing boots 52 with movably controlling overspeed governor 16 between the boots 53.
Next, action is described.When car 8 moved, driven shaft 26 rotated corresponding to moving of car 8, and displacement body 28 is shifted along driven shaft 26 accordingly with the rotative speed of driven shaft 26.When car 8 moved with common operating speed, the shift amount of displacement body 28 was little, and switch lever 51 can not be operated portion's 42 operations.
When making for some reason the speed of car 8 rise and reach first when setting hypervelocity speed that switch lever 51 is operated portion's 42 operations.Thus, send danger signal from hypervelocity switch for over speed detection 21 to control setup 6.When control setup 6 was received danger signal, the control by control setup 6 forcibly made the running of elevator stop.
After this, although the control that stops in the running of having carried out based on control setup 6 but the speed of car 8 still further rise and reach second when setting hypervelocity speed, the maintenance of 60 pairs of clamping rpoles 58 of press section material is thrown off, and overspeed governor 16 is by being held in fixedly boots 52 and movably between the boots 53.Thus, the mobile of overspeed governor 16 stops, and car 8 moves with respect to overspeed governor 16.
When car 8 moved with respect to overspeed governor 16, motion arm 11 was operated, and was controlled the action of car guide rail by emergency braking device 10.Thus, directly to car 8 brake activation power.
Then, the action to rope sheave linkage 20 describes.When car 8 rose, driven shaft 26 was just changeing.Thus, produce positive current by electrical generator 43.Positive current from electrical generator 43 is cut off by rectifying device 44, can not be transported to magnet coil 40.Thus, plunger 39 is displaced to punctured position, and each telescopic boom 33 shrinks.That is, when car 8 rose, respectively getting rid of ball 32 be to revolve round the sun in the center with driven shaft 26 under the state that each telescopic boom 33 shrinks.
On the other hand, when car 8 descends, driven shaft 26 counter-rotatings.Thus, produce negative current by electrical generator 43.Negative current from electrical generator 43 is transported to magnet coil 40 by rectifying device 44.Thus, plunger 39 is displaced to extended position, each telescopic boom 33 elongation.That is, when car 8 descended, respectively getting rid of ball 32 be to revolve round the sun in the center with driven shaft 26 under the state of each telescopic boom 33 elongation.
Because the revolution radius that respectively gets rid of ball 32 is big when rising than car 8 when car 8 descends, the rotative speed of the driven shaft 26 that therefore is used to make displacement body 28 be displaced to following each position is low when rising than car 8 when car 8 descends, and described position is: switch lever 51 operated positions; And press section material 60 is displaced to the position of removing the position.That is, first and second is low when setting the hypervelocity speed and rising than car 8 when car 8 descends.
In such lift appliance, respectively getting rid of each telescopic boom 33 that ball 32 links to each other with driven shaft 26 and can stretch velocity limiter 12, and be provided with make each telescopic boom 33 length when just changeing and counter-rotating the time form the displacement setting device 30 of different length, therefore can make the revolution radius that gets rid of ball 32 different when car 8 rises and during decline.Thus, can being used in unusual first and second of the speed that detects car 8, to set the hypervelocity speed different when the rising of car 8 and during decline.In addition,, therefore number of components can be reduced, the reduction of cost can be realized because two speed limiting mechanisms having set hypervelocity speed respectively needn't be set.And, owing to can also realize velocity limiter 12 single-piece miniaturizations, therefore also can realize the downsizing of lift appliance.
In addition, displacement setting device 30 has: electrical generator 43, and it utilizes the rotation of driven shaft 26 to generate electricity; And rectifying device 44, in its electric power that only will send by electrical generator 43, when driven shaft 26 is just changeing and the electric power of the either party during counter-rotating be delivered to the magnet coil 40 of each telescopic boom 33, therefore, can not need from exterior power supply, can make the velocity limiter 12 and the moving direction of car 8 carry out work accordingly more reliably.
In addition, only by adjusting the punctured position and the extended position of plunger 39, in the time of just can easily carrying out the rising of car 8 and the adjustment of each the first and second setting hypervelocity speed when descending.
In addition, in above-mentioned example, rectifying device 44 is only carried negative current to magnet coil 40, but also can adopt the rectifying device of only positive current being carried to magnet coil 40 44.When the first and second setting hypervelocity speed settings in the time of like this, car 8 can being descended must rise than car 8 first and second set hypervelocity speed height.
