Detailed description of the invention
Below, with reference to accompanying drawing, one embodiment of the present invention is described.
In the drawings and in which, identical Reference numeral is adopted to be described for identical or similar component and position.
Fig. 1 is the constructional drawing of the lift facility of an embodiment of the present invention, and Fig. 2 is the birds-eye view of hoist trunk 1.
As shown in the figure, it is connected to each other that lift car 2 and counterbalanced weight 3 pass through hoist cable 15, and this hoist cable 15 is wound on winch and actuating device 4, by driver 4, lift car 2 and counterbalanced weight 3 is elevated as well-bucket in hoist trunk 1.
Be elevated under being configured to the state that counterbalanced weight 3 guides by guide rail 22 in both sides in the present embodiment, lift car 2 is elevated under the guiding of guide rail 21.
Actuating device 4 is controlled by control setup 5.
In hoist trunk 1, hoist trunk endoseptum 7 extends near the bottom of hoist trunk 1 from the near top of hoist trunk 1, thus by the hoist trunk 1b of the hoist trunk 1a and counterbalanced weight 3 that are separated into lift car 2 in hoist trunk 1.
As shown in Figure 1, drop in order to the operating personnel carrying out maintenance activity on car at the stop position of the topmost in hoist trunk 1 of lift car can be prevented, being arranged to hoist trunk endoseptum 7 higher than car top board 2a at the rational height of hoist trunk 1 near top, and this rational height is set to the height that can not interfere with the hoist cable 15 as equipment in hoist trunk, actuating device 4 etc. of the near top being arranged on hoist trunk 1.
As long as be set to by the rational height of hoist trunk endoseptum 7 identical with the height and position of the car upper armrest 6 (representing with long and short dash line in FIG) on the car top board 2a being arranged on the elevator not arranging this next door 7, just can fully play the effect preventing operating personnel from dropping.
That is, by arranging this hoist trunk endoseptum 7, even if do not arrange elevator car upper armrest 6 on car top board 2a, also can fully play the effect preventing operating personnel from dropping.
By hoist trunk endoseptum 7, the operating personnel carrying out maintenance examination operation on lift car 2 can be avoided to drop, so do not need to arrange elevator car upper armrest 6 separately, thus, the size of space between the top that can reduce car top board 2a and hoist trunk 1, can reduce top dimension, thus can realize a kind of lift facility of compact conformation, it can reduce the overall volume of hoist trunk 1.
At the stop position of the foot in hoist trunk 1 of lift car 2, by hoist trunk endoseptum 7 bottom hoist trunk 1 near rational height be set to the height and position of lift car 2 side till, and this rational height is set to the position that can not interfere with the equipment being arranged on hoist trunk 1 bottom.
Fig. 2 is the birds-eye view of hoist trunk 1, in order to avoid the not shown operating personnel carrying out operation at car top board 2a drops, by between hoist trunk endoseptum 7 and the circumference of car top board 2a be disposed on about 300mm within.
Based on identical reason, within the size of space between the circumference of car top board 2a and the wall portion of hoist trunk 1 is also arranged on about 300mm.
Below, the maintenance examination operation of the counterbalanced weight 3 carried out at car top board 2a is described with reference to Fig. 3 and Fig. 4.
Fig. 3 represents the position relationship of lift car 2 when carrying out maintenance examination to the counterbalanced weight 3 shown in Fig. 1 and counterbalanced weight 3, and Fig. 4 is the figure observed from the A of Fig. 3.
As shown in Figure 3 and Figure 4, near the roughly pars intermedia of this hoist trunk 1, the position interlocked when lift car 2 is elevated with counterbalanced weight 3 is provided with the aperture area opening 7a roughly the same with the horizontal projected area of counterbalanced weight 3, utilize this opening 7a, the operating personnel used as the place of keeping a foothold by car top board 2a can carry out maintenance examination operation to counterbalanced weight 3.
As this maintenance examination operation, the maintenance examination comprising the described counterbalanced weight of the guiding 3 counterbalanced weight guiding device 3c of movement on guide rail 22 be arranged between described counterbalanced weight 3 and guide rail 22 and the maintenance examination etc. lubricating oil being coated the gas feeder 3b of described guide rail 22 be arranged on counterbalanced weight 3.
In addition, as shown in Figure 4, when carrying out maintenance examination to above-mentioned counterbalanced weight 3, because the side contrary with lift car 2 at opening 7a is provided with counterbalanced weight 3, so operating personnel can not drop from the hoist trunk 1b of counterbalanced weight 3, as the opening 7a that the top formation aperture area of the horizontal projected area at counterbalanced weight 3 is larger, by arranging balance heavy side Anti-fall component 3a, the safety of operating personnel can be guaranteed.
The transverse width of hoist trunk endoseptum 7, can be as shown in Figure 2, in the mode that two ends contact with the wall of hoist trunk 1, be arranged to identical with the whole transverse width of hoist trunk 1, and also as shown in Figure 5, the transverse width that maintainer can be avoided to drop from car top board 2a can be arranged to.
That is, within preferably the size of space between car top board 2a and hoist trunk 1 being arranged on about 300mm.
In the above description, the situation that counterbalanced weight 3 is arranged on rear side of lift car 2 is illustrated.On the other hand, as shown in Figure 6, when being applied to counterbalanced weight 3 and being arranged in the lift facility of lift car 2 side, also effect same as the previously described embodiments can be obtained.
Fig. 7 is the constructional drawing of the lift facility of other embodiments of the present invention, and actuating device 4 and control setup 5 are arranged on the bottom in hoist trunk 1.
According to the lift facility of these other embodiments, the method for winding of hoist cable 15 is as follows: hoist cable 15 extends downward from rope end 15a, be wound up into after on lift car lower pulley 2b, extend towards back upper place, and be wound on deflection sheave 30a, after this extend downward, and be wound on actuating device 4, then extend towards back upper place, and be wound on deflection sheave 30b, after this again extend downward, and be wound on counterweight block 3d, after this extend towards back upper place, and be fixed on rope end 15b.
Fig. 8 represents the situation during counterbalanced weight maintenance examination in other embodiments.
These other embodiments relate to the lift facility of the mechanical cell-type not arranging Machine Room, in this lift facility, the same with above-mentioned embodiment, by arranging hoist trunk endoseptum 7, successfully can carry out the maintenance examination operation of counterbalanced weight 3 at car top board 2a, and reliably can guarantee the safety of carrying out the maintainer of operation at car top board 2a.
Counterbalanced weight maintenance examination in other embodiments also comprises the Inspection of counterweight block 3d.
Description of reference numerals is as follows:
The lifting space of 1 hoist trunk, lift car, the lifting space of 1a counterbalanced weight, 1b, 2 lift cars, 2a car top board, 3 counterbalanceds weight, 3a balances heavy side Anti-fall component, 3b gas feeder, 3c counterbalanced weight guiding device, 3d counterweight block, 4 actuating devices, 5 control setups, 6 elevator car upper armrests, 7 hoist trunk endoseptums, 7a opening, 15 hoist cables, 21 car guide rails, 22 counter-weight guide rails
