Below, best example of the present invention is described with reference to accompanying drawing.
The back view of the state when Fig. 1 is the manual rotary operation of Winch for elevator (gearless winch) of an example of expression example of the present invention, Fig. 2 is the cutaway view of the Winch for elevator of Fig. 1.
Among the figure, shell 1 has outer cover body 2 that is fixed on the fixed part and the discoideus back plate 3 that is installed on the outer cover body 2.At the center of outer cover body 2, be fixed with main shaft 4.On main shaft 4, being installed with main shaft 4 by bearing 6 is the rotating part 5 that the center is rotated.
Rotating part 5 has drive pulley 7 cylindraceous and as the drg drum 8 cylindraceous of drg swivel.Drive pulley 7 and drg drum 8 form on rotating part 5.On drive pulley 7, volume is hung the many main ropes 9 of elevator.Main rope 9 is inserted in a plurality of rope grooves on the peripheral part that is located at drive pulley 7.
In the inboard of drg drum 8, dispose the brake gear body 12 that drg drum 8 is braked.Brake gear body 12, quilt are carried to be bearing on the plate 3 of back.Again, the supporting structure of brake gear body 12 is not shown.Brake gear (magnet stopper) 13 to drive pulley 7 is braked has drg drum 8 and brake gear body 12.
On the plate 3 of back, be provided with the outer a plurality of peristome 3a that maintain in the face of brake gear body 12 that are used for from shell 1.When turning round usually, utilize lid (not shown) that peristome 3a is closed.As mentioned above, plate 3 upper supports have brake gear body 12 in the back, thereby peristome 3a can not be circular and be divided into a plurality of.
Therefore, when peristome 3a was opened, the part of the end face of the 2nd end 8b of drg drum 8 was being covered by back plate 3 all the time.But when peristome 3a was opened, the anglec of rotation of at least 2 breach 8c and drg drum 8 was irrespectively exposed from peristome 3a.
With manually making rotating part 5 be rotated the hand scroll handle 14 of usefulness, have: the flat handle body 15 that relative to each other the 1st and the 2nd 15a, 15b are arranged; Be located at a plurality of (a pair of) projection 16 of the handle side engagement section that the 1st 15a goes up, conduct engages with breach 8c; Be located at the 2nd handle 17 on the 15b.Handle body 15 has the length bigger than the diameter of shell 1.Again, handle body 15 also can be more less than shell 1, but with it make big, handle 17 leave main shaft 4 far away more, just can easily operate handle body 15 with more little power.
On the end of back plate 3 sides of main shaft 4, be provided with speed detector 18.Speed detector 18 is around the end of main shaft 4.
Then, action is described.When the common running of elevator, hand scroll handle 14 unloads from rotating part 5, utilizes the peristome 3a that covers back plate 3 to close.When the maintenance of brake gear 13 is checked, unload, make peristome 3a to open on lid again.In the occasion of the maintenance transposing of carrying out speed detector 18, back plate 3 is unloaded from outer cover body 2 again.
Again, owing to certain take place unusually electric currents in the motor stator 10 do not flow the fault that waits, take advantage of the car that is loaded with the passenger to stop at the occasion of floor gap, with drive pulley 7 is rotated, and make car move to hithermost floor.In this occasion, peristome 3a is opened, and for example, as shown in Figure 1, hand scroll handle 14 is installed on the rotating part 5 (drg drum 8).And the limit makes brake gear 13 unclamp the limit and hand scroll handle 14 is operated and rotating part 5 is rotated.
At this moment, because projection 16 is subjected to stopping of back plate 3, so hand scroll handle 14 is rotated continuously.Therefore, for example, if after hand scroll handle 14 rotated to the position of long and two-short dash line from the position of the solid line of Fig. 1, closed brake gear 13 unloaded hand scroll handle 14 from rotating part 5.Then, once more brake handle 14 is installed in the position of solid line, the limit makes brake gear 13 unclamp the limit and makes 14 rotations of hand scroll handle.By repeating such operation, drive pulley 7 is little by little rotated, and car is moved to hithermost floor.
On such Winch for elevator, be provided in a side of on the rotating part 5 on the main shaft 4 owing to the breach 8c that will engage with hand scroll handle 14 is not provided in a side of, so, also can hand scroll handle 14 be installed from the same side of speed detector 18 in the occasion that speed detector 18 is installed on the main shaft 4.Therefore, can be with the axial side of maintenance spatial concentration, so can dwindle the maintenance space that to guarantee at main shaft 4.Therefore, in narrow space, also Winch for elevator can be set, be actv. to elevator of being applied to machine House-less etc.
Again, even hand scroll handle 14 can be installed, so can more easily carry out the manual rotary operation of drive pulley 7 owing to do not unload speed detector 18 yet.In main shaft 4 non-rotary occasions, also can utilize hand scroll handle 14 to be rotated manually to make drive pulley 7 again.
Again, because breach 8c is that the center is disposed mutually symmetrically with main shaft 4, so, also the rotational force from hand scroll handle 14 can be passed to rotating part 5 efficiently although support without 4 pairs of hand scroll handles 14 of main shaft.
Again, expose,, can improve the operation of the manual rotary operation of drive pulley 7 so, also hand scroll handle 14 can be installed even do not unload plate 3 afterwards because breach 8c makes from the peristome 3a of the maintenance usefulness of brake gear 13.
Again, owing to use the integrally formed rotating part 5 of drive pulley 7 and drg drum 8 and breach 8c is arranged on the 2nd end 8b of drg drum 8, so energy will be passed to drive pulley 7 efficiently from the rotational force of hand scroll handle 14.
Can dwindle the maintenance space from carrying out the operation of hand scroll handle 14 with the same side of the maintenance operation of brake gear 13 again.
Again, because rotary unit side engagement portions is made breach 8c and the handle side engagement section is made projection 16, so can be with simple structure, hand scroll handle 14 is engaged with rotating part 5.
In above-mentioned example, represented breach 8c as rotary unit side engagement portions, but also can as shown in Figure 3 bolt hole 8e be arranged on the end face 8d of drg drum 8 as rotary unit side engagement portions again.This occasion, the materials handling in the time of also bolt hole 8e can being used in factory, assembling.
In above-mentioned example, breach 8c is located at the inner peripheral surface side of the 2nd end 8b, and, also breach 8f can be arranged on the outer peripheral face side of the 2nd end 8b as long as the 2nd end 8b integral body is exposed from back plate 3c again.
Again, in above-mentioned example, peristome 3a has been divided into 2, but also peristome can be divided into 3.This occasion is as long as be configured on the summit of equilateral triangle rotary unit side engagement portions just passable.Similarly, in the occasion that peristome is divided into more than 4, also can use the present invention.
Again, in above-mentioned example, main shaft is being fixed, and the winch to main shaft and rotating part are rotated integratedly also can be used the present invention.
Again, in above-mentioned example, breach 8c is arranged on the drg drum 8 in the rotating part 5, and rotary unit side engagement portions also can be arranged on the part beyond the drg swivel of for example drive pulley or motor rotor etc., rotating part.
