Detailed description of the invention
Hereinafter, with reference to the accompanying drawings embodiments of the present invention are illustrated. It addition, in the drawings, identical label represents identical or corresponding part.
Embodiment 1
Fig. 1 is the overall figure of the elevator of the safety device illustrating the elevator including embodiments of the present invention 1. Elevator 1 possesses: the hoistway 3 vertically extended; And it is configured to car 5 and the counterweight 7 of movement in hoistway 3. Car 5 is guided along car guide rail 9, and this car guide rail 9 is fixed on the wall delimiting hoistway and upwards lower extension. Additionally, counterweight 7 is also guided along the upwards lower counter weight guide track omitting diagram extended.
It is arranged over machine room 11 at hoistway 3. Machine room 11 is provided with traction machine 13 and limiter of speed 15. Traction machine rope sheave 13a and deflector sheave 17 roll at traction machine 13 hang with main rope 19. Car 5 and counterweight 7 are suspended on main rope 19. If driving main rope 19 by traction machine 13, then car 5 and counterweight 7 lift towards upper and lower opposite direction mutually.
The safety device of elevator possesses: is located at the brake hard part 51 on car 5, is bearing in governor sheave 15a and loop portions 53 on governor tension pulley 15b and emergency braking action portion 55.
Brake hard part 51 is to be arranged on car 5 in the way of lifting integratedly with car 5. The structure of brake hard part 51 is not particularly limited, as long as known form. Not shown brake shoe is pressed against on car guide rail 9 by the action force inputted from emergency braking action portion 55, gives the brake force based on frictional force to car 5. If that is, brake hard part 51 function like this.
The structure in emergency braking action portion 55 is also without being particularly limited to, as long as known form. Emergency braking action portion 55 connects between brake hard part 51 and loop portions 53, as long as and following structure: when car 5 suddenly becomes different from the speed of loop portions 53 (also including meaning the zero velocity of the halted state of loop portions 53) speed, it is possible to make brake hard part 51 action according to the speed difference of car 5 and loop portions 53. One example is, emergency braking action portion 55 includes arm-tie 61 and upper connecting rod 63 as linkage.
Loop portions 53 includes overspeed governor 71, the counterweight 73 of inertia action, shock-absorbing spring 75 and the service portion 77 linked with emergency braking action portion 55. Loop portions 53 has with governor sheave 15a and governor tension pulley 15b for two ends and vertically longer the closed loop shape extended. Loop portions 53 at least partly carries out turnover action in the scope that car 5 lifts in hoistway 3. Additionally, overspeed governor 71 possesses flexibility, and when being wrapping with on governor sheave 15a and governor tension pulley 15b, the guiding circular arc along governor sheave 15a and governor tension pulley 15b bends.
As shown in Figure 1, when the imaginary line of the top to link governor sheave 15a and the bottom of governor tension pulley 15b distinguishes the opposition side R of cage side F and cage side for boundary, in the cage side of loop portions 53, it is arranged in sequence with overspeed governor 71, counterweight 73, shock-absorbing spring 75, service portion 77, overspeed governor 71 from above.
According to the present embodiment 1 so constituted, it is possible to obtain following advantage. First, when wanting to make brake hard part action more delicately by inertia action, it is considered to the quality increasing the inertia system including overspeed governor is tackled, and then, it that case, consider that the quality increasing governor sheave or governor tension pulley is tackled. But, if for the quality increasing governor sheave or governor tension pulley, and carrying out the big footpath of governor sheave or the big footpath of governor tension pulley, then the required space that processes of overspeed governor broadens extensively, it is possible to disturb mutually with other lift facility. On the other hand, in present embodiment 1, in loop portions, specifically, it is provided with counterweight on the top of shock-absorbing spring, therefore, it is possible to make the diameter of governor sheave and the diameter of governor tension pulley and original the same change and increase the quality of inertia system. Namely, it is possible to do not rely on the maximization of governor tension pulley and promote the stabilisation of the emergency braking action based on inertia action.
In addition, owing to governor sheave, governor tension pulley, emergency braking action portion and brake hard part are not changed, it is possible to use the governor sheave, governor tension pulley, emergency braking action portion and the brake hard part that use, therefore in the past, compared with special designs, equipment cost reduces. In modernization at elevator etc., even if when the quality of inertia system must be increased, it is also possible to easily in the end add counterweight. Additionally, due to counterweight is installed near shock-absorbing spring and service portion (upper pull-rod), therefore, it is easy to suppress equipment interference each other. Even if additionally, when elevator stops suddenly, under the effect of the shock-absorbing spring being arranged on service portion (upper pull-rod), the tension force of overspeed governor will not disappear.
Embodiment 2
It follows that use Fig. 2 that embodiments of the present invention 2 are illustrated. Fig. 2 is about the figure of the part near embodiments of the present invention 2, the emergency braking action portion that illustrates in loop portions. It addition, in present embodiment 2, except the part of following description, identical with above-mentioned embodiment 1.
The invention is not restricted to arrange counterweight on the top of shock-absorbing spring, as long as being provided with counterweight in loop portions, it is also possible to be other form. Present embodiment 2 is its example. In present embodiment 2, loop portions 153 includes overspeed governor 71, counterweight 73, shock-absorbing spring 75 and the service portion 77 linked with emergency braking action portion 55, at the cage side F of loop portions, it is arranged in sequence with overspeed governor 71, shock-absorbing spring 75, service portion 77, overspeed governor 71, counterweight 73, overspeed governor 71 from above.
According to such present embodiment 2, it is also possible to obtain the advantage same with embodiment 1.
Embodiment 3
It follows that use Fig. 3 that embodiments of the present invention 3 are illustrated. Fig. 3 is about the figure of embodiments of the present invention 3 and Fig. 1 same modality. It addition, present embodiment 3 is except the part of following description, identical with above-mentioned embodiment 1.
Present embodiment 3 is also an example of the present invention not arranging counterweight on the top of shock-absorbing spring. In present embodiment 3, loop portions 253 includes overspeed governor 71, counterweight 73, shock-absorbing spring 75 and the service portion 77 linked with emergency braking action portion 55, it is provided with overspeed governor 71, shock-absorbing spring 75 and service portion 77 at the cage side F of loop portions 253, is provided with overspeed governor 71 and counterweight 73 at the opposition side R of the cage side of loop portions 253.
According to such present embodiment 3, it is also possible to obtain the advantage same with embodiment 1. Additionally, especially, in present embodiment 3, the structure of the cage side F of loop portions 253 has completely without the advantage being modified from existing structure.
Above, with reference to preferred embodiment present disclosure having been carried out specific description, it is, however, obvious that according to the basic technological thought of the present invention and teaching, as long as those skilled in the art, then various deformation can be adopted.
