Rotatably support has upside to recover bar 43 and downside recovers bar 44 respectively on back plate 16, and above-mentioned upside recovers bar 43 and downside to recover bar 44 are positions of making pawl 28 from control position to removing a pair of recovery of moving the position with bar (Fig. 2, Fig. 6).Upside recovery bar 43 and downside recovery bar 44 are the curved plate shap parts that roughly circumferentially extend along ratchet 26.In addition, upside recover bar 43 and downside recover bar 44 be configured in sheave shaft 15 around, and be configured between back plate 16 and the ratchet 26.In addition, upside recovers bar 43 and downside recovers bar 44 about comprising the horizontal surface balanced configuration of sheave shaft 15.Rotatably support has upside to recover an end 43a of bar 43 and the end 44a that downside recovers bar 44 respectively on back plate 16.
Be provided with the recovery projection 45 of extending to back plate 16 sides from pawl 28 in the side of pawl 28.By upside recover bar 43 and downside recover bar 44 with recover with protruding 45 butts in radius vector laterally rotate, pawl 28 moves to the releasing position from control position.Upside recovery bar 43 and downside recover bar 44 and be configured as: even recover to recover the peripheral part of bar 43 and either party's butt that downside recovers the peripheral part of bar 44 with projection 45 and upside, pawl 28 still moves to removing the position.
The other end 43b that upside recovers bar 43 is provided with the upside recovery bar pin 46 that runs through back plate 16.In addition, the other end 44b of downside recovery bar 44 is provided with the downside recovery bar pin 47 (Fig. 4, Fig. 6) that runs through back plate 16.
At back plate 16 upper supports connecting rod mechanism 50 is arranged, this connecting rod mechanism 50 is used to make worker's arm of action 38, upside to recover bar 43 and downside to recover bar 44 link each other (Fig. 2, Fig. 4).Connecting rod mechanism 50 has: recover bar with upside and recover bar pin 47 bonded assembly upper links 51 with pin 46 and downside; And with upside recover bar with pin 46 and working beam with mount pin 41 bonded assembly lower link 52.
Here, Fig. 8 is the enlarged drawing of the upper links 51 in the presentation graphs 4.As shown in the figure, upper links 51 is provided with: slotted hole 53, and upside recovers bar can pass through this slotted hole 53 slidably with pin 46; And make downside recover bar with 47 through holes that pass through 54.
Be provided with extension spring 55 between upper links 51 and back plate 16,55 pairs of upper links 51 of this extension spring are to making downside recover the direction application of force that bar 44 radius vectors turn to the inside.Upper links 51 by extension spring 55 and with respect to back plate 16 by the application of force upward.
Be positioned at the common time of releasing position in movable side rope clamping section 35, upside recovers bar is positioned at the slotted hole 56 of the bottom of slotted hole 53 of upper links 51 and lower link 52 with pin 46 upper end, and working beam is positioned at the upper end (Fig. 2, Fig. 4) of the slotted hole 57 of lower link 52 with mount pin 41.
Fig. 9 is the cutaway view along the IX-IX line among Fig. 6.In the drawings, be provided with the slot part 61 of terminal part (part) insertion that makes work use engagement piece 27 in the side of back plate 61.Work was extended with the moving direction of engagement piece 27 when slot part 61 rotated along ratchet 26.
Next, action is described.When the rising or falling speed of car 2 reaches the first mistake speed, owing to fly to put 19 because of centnifugal force rotates, work piece 20 and switch lever 22a butt, thus switch lever 22a is rotated.Thus, car stops with switch 22 work, and the power supply of towing machine 4 is cut off, and car 2 stops by the brake equipment of towing machine 4.
In addition, for example the situation of breaking at main rope 8 is inferior, even towing machine 4 stops, car 2 also can not stop but continuing descending, when the descending speed of car 2 reaches the second mistake speed (setting speed), fly to put 19 and further rotate, meanwhile, the rotation quantitative change of operation bar 24 is big, makes operation bar 24 unclamp with engaging of pawl 28.Like this, pawl 28 rotates to control position from removing the position by the application of force of force application spring, thereby engages with the tooth of ratchet 26.Thus, ratchet 26 rotates slightly with the anticlockwise direction of governor sheave 13 in Fig. 6.
When ratchet 26 rotations, work makes worker's arm of action 38 rotate with the upper end butt of engagement piece 27 with worker's arm of action 38.Thus, worker's arm of action 38 gets loose with parts 37 from fastening, and downwards constrained moves by deadweight for movable side rope clamping section 35.By the antagonistic force of the fixation side rope clamping section 32 that movable side rope clamping section 35 is born this moment, expansion link 34 is that the center is rotated and is compressed simultaneously with bolster 33.Thus, push with spring 36 and be compressed, movable side rope clamping section 35 across overspeed governor 12 by powerful by being pressed on the fixation side rope clamping section 32.Like this, 31 actions (run action) of rope clamping mechanism make overspeed governor 12 be braked.When overspeed governor 12 stops circulation time, by the lasting decline of car 2, working beam 9a is operated, and makes emergency braking device 9 actions.
Figure 10 is the instruction diagram of velocity limiter 10 state usually time the in the presentation graphs 4.As shown in the figure, in the common time, worker's arm of action 38 is configured in the releasing position with fastening parts 37 fastenings, movable side rope clamping section 35.In addition, upside recovers the deadweight of bar 43 by the other end 43b and is in the state that radius vector turns to the inside, and downside recovers the application of force of bar 44 by extension spring 55 and is in the state that radius vector turns to the inside.Under this state, upside recovers the bottom butt of bar with pin 46 and slotted hole 53, the working beam upper end butt of mount pin 41 and slotted hole 57.
The instruction diagram of the state when Figure 11 is velocity limiter 10 work of representing among Figure 10.When rope clamping mechanism 31 work, worker's arm of action 38 gets loose with the fastening of fastening with parts 37, and movably move to constrained from the releasing position side rope clamping section 35.At this moment, the position that connecting rod mechanism 50, upside recover bar 43 and downside recovery bar 44 is held, and working beam slides to the bottom from the upper end of the slotted hole 27 of lower link 52 with mount pin 41.
Next, the action of the recovery after the run action of velocity limiter 10 is described.Figure 12～Figure 14 is the instruction diagram of the recovery action of the velocity limiter 10 among explanation Figure 11, Figure 12 is the instruction diagram that the downside among expression Figure 11 recovers the state after bar 44 radius vectors laterally rotate, Figure 13 is the instruction diagram of the state after the lower link 52 among expression Figure 12 is moved upward, and Figure 14 is the instruction diagram that the upside among expression Figure 13 recovers the state after bar 43 radius vectors laterally rotate.
For example, when making remote manipulation overcome the application of force of extension spring 55 and when drop-down, also spurred downwards with line 60 bonded assembly upper links 51 with remote manipulation with line 60 by operating away from the place of velocity limiter 10 at stop etc.At this moment, upper links 51 is slided along slotted hole 53 with pin 46 with respect to upside recovery bar.Thus, downside recovers bar and moves downwards with pin 47, and downside recovers bar 44 radius vectors and laterally rotates.After this, downside recovers bar 44 and the bottom butt (Figure 12) of the lower beam that is arranged at back plate 16 with slotted hole 49 (Fig. 4).
Then, when remote manipulation is further applied lower pulling force with line 60, be applied to remote manipulation with the reaction force acts of the lower pulling force of line 60 the part that contacts with line 60 with remote manipulation in line installing component 59.The antagonistic force that acts on line installing component 59 comprises composition upward, and thus, lower link 52 is being spurred when slotted hole 56 slides upward recovering bar 43 with respect to upside.Afterwards, upside recovers the bottom butt of bar with pin 46 and slotted hole 56.At this moment, movable side rope clamping section 35 also is moved upward (Figure 13) with lower link 52.
After this, by further spurring lower link 52 upward, upside recovers bar and also is moved upward with pin 46, thereby upside recovers bar is used slotted hole 48 (Fig. 4) with pin 46 and the upper boom that is arranged at back plate 16 upper end butt.Like this, upside recovery bar 43 radius vectors laterally rotate.At this moment, upside recovers bar slotted hole 53 slips of pin 46 along upper links 51.In addition, movable side rope clamping section 35 also moves to the releasing position, by the application of force of extension spring 42, and worker's arm of action 38 and fastening parts 37 fastenings (Figure 14).
When recovering with projection 45 (Fig. 2, Fig. 6) when being positioned at predetermined scope, upside recovers bar 43 and downside and recovers bar 44 radius vectors and laterally rotate, and like this, upside recovers bar 43 and downside and recovers the either party of bar 44 and recovery with protruding 45 butts.Thus, pawl 28 overcomes the application of force of force application spring and rotates, thereby returns to and move the releasing position that bar 24 engages from the control position that the tooth with ratchet 26 engages.That is, recover under the situation on either party's the rotation path that bar 43 and downside recover bar 44 recovering to be positioned at projection 45 upside, pawl 28 can return to the releasing position from control position.
Like this, pawl 28 is moved to remove the position, make movable side rope clamping section 35 move to the releasing position, thus, finish the recovery of velocity limiter 10.
In this velocity limiter 10, ratchet 26 is provided with work engagement piece 27, this work is used for making 31 actions of rope clamping mechanism by worker's arm of action 38 is moved with engagement piece 27, back plate 16 is provided with and is used for the slot part 61 of insertion work with the part of engagement piece 27, therefore, the ratchet 26 when using engagement piece 27 with worker's arm of action 38 butts and the elastic deformation of back plate 16 by work, can prevent that worker's arm of action 38 from coming off with the gap between engagement piece 27 and the back plate 16 from work, can make worker's arm of action 38 move more reliably.Therefore, velocity limiter 10 is worked more reliably.
In addition, on back plate 16, be provided with the end 43a separately that upside recovers bar 43 and downside recovery bar 44 rotationally, 44a, above-mentioned upside recover bar 43 and downside recover bar 44 be configured in sheave shaft 15 around, and be bent to form to surrounding sheave shaft 15, push away on the either party that upside recovery bar 43 that pawl 28 is rotated to the direction of leaving sheave shaft 15 (radial outside) and downside recover bar 44, thereby turn to the releasing position from control position, therefore, the position of pawl 28 is recovered bar 43 by upside and downside recovery bar 44 becomes big to removing the scope that pushes away on the position, thereby can improve the reliability of the recovery action of pawl 28.
In addition, worker's arm of action 38 recovers bar 43 with upside and downside recovery bar 44 links each other by connecting rod mechanism 50, the remote manipulation that is used to connecting rod mechanism 50 is moved is connected with connecting rod mechanism 50 with line 60, therefore, even the operating personnel does not enter in the hoistway 1 so that velocity limiter 10 recoveries for example only by from operating and remote controllings such as stop behaviour active line 60, just can make connecting rod mechanism 50 move, pawl 28 is moved to removing the position, thereby can make movable side rope clamping section 35 move to the releasing position.So, can easily carry out resuming operation after the run action of velocity limiter 10.
In addition, pedestal 14 has opposed a pair of back plate 16,17 mutually, velocity limiter 13, snap fastener 30, worker's arm of action 38 and rope clamping mechanism 31 are configured in respectively between back plate 16 and the back plate 17, therefore, the width dimensions of velocity limiter 10 can be dwindled, the miniaturization and the lightweight of velocity limiter 10 can be realized.In addition, owing to can make back plate 16,17, therefore, can process many pieces of overlapped metal sheets simultaneously, thereby can easily carry out the manufacturing of pedestal 14 making back plate at 16,17 o'clock for identical shaped.
