The specific embodiment
Below, with reference to accompanying drawing preferred implementation of the present invention is described, in each figure, give identical symbol for parts or position identical, that be equal to.
Fig. 1 is the constructional drawing that the towing machine 3 of expression embodiment of the present invention 1 is installed in the state in the hoistway 1.
In this elevator, on the wall of hoistway 1, be fixed with towing machine 3 by beam 2.On the rope sheave 4 of towing machine 3, be wound with rope 5.One end of this rope 5 is connected with car 7 by cage side diversion sheave 6.The other end of rope 5 is by being connected with counterweight 9 heavy side diversion sheave 8.
Fig. 2 is the front view of the towing machine 3 in the presentation graphs 1, and Fig. 3 is the direction of arrow cutaway view that the towing machine 3 among Fig. 2 is cut open along the A-A line.
In this towing machine 3, opposed motor side housing 11 is fixed with each other with drg side body 12.Central part at motor side housing 11 and drg side body 12 is fixed with anchor shaft 10.On this anchor shaft 10, can be provided with rope sheave 4 by bearing 13 with rotating freely.Be formed with the brake wheel (break drum) 14 of concavity shape on rope sheave 4 continuously, above-mentioned rope sheave 4 has a plurality of grooves 15 that form along its hand of rotation, and the brake wheel 14 of above-mentioned concavity shape radially extends, and outstanding to axis direction.The most peripheral end face 20 of brake wheel 14 is positioned at motor side housing 11 sides with respect to groove 15.On the outer peripheral face of brake wheel 14, separate equal intervals along the hand of rotation of rope sheave 4 and be fixed with a plurality of permanent magnets 16.At the outside diameter of brake wheel 14, stator 19 and permanent magnet 16 opposed to each other fixed configurations in motor side housing 11.Stator 19 is by circular iron core 17 and be wound with coil of conductive wire 18 constitute on this iron core 17.In addition, constitute electrical motor by permanent magnet 16 and stator 19.
In drg side body 12, the symmetric position that is line of centers with above-mentioned A-A line is provided with a pair of brake control lever 22, and this a pair of brake control lever 22 can be that freely rotate at the center with rest pin 21.
As shown in Figure 5, portion is triangular in shape outstanding to motor side housing 11 sides therebetween for each brake control lever 22.As shown in Figure 2, be penetrated with stepwise bolt (shoulder bolt) 23, screwed togather brake shoe 24, brake surface 25 press contacts of this brake shoe 24 and the inner face side of brake wheel 14 at the leading section of this stepwise bolt 23 at this protrusion.Side opposite with brake surface 25 at brake shoe 24 is formed with hemispheric recess 26.Be provided with the packing ring 27 of dome shape between brake shoe 24 and brake control lever 22, this packing ring 27 recess 26 relatively slides.Between the head 28 of stepwise bolt 23 and brake control lever 22, be provided with coil spring 29 with compressive state.Brake shoe 24 by the elastic force of this coil spring 29 by to the brake control lever 22 side application of forces.
As Fig. 3 and shown in Figure 5, under rope sheave 4, be provided with the retarding spring 30 that is fixed on the drg side body 12.30 pairs of a pair of brake control levers 22 of this retarding spring are to the direction application of force that is separated from each other.
In addition, as Fig. 3 and shown in Figure 5, under rope sheave 4, be provided with the electromagnet 31 that is fixed on the drg side body 12.
As Fig. 4, Fig. 6 and shown in Figure 7, near rope sheave 4, be provided with the retaining rope parts 32 of pair of L word shape, these a pair of retaining rope parts 32 are fixed on the drg side body 12, thereby prevent that by these retaining rope parts 32 rope 5 breaks away from the groove 15 of rope sheave 4.
In the towing machine 3 of said structure, by to coil 18 energising, under the effect that results from the electromagnetic induction between stator 19 and the permanent magnet 16, brake wheel 14 and rotate with the rope sheave 4 of brake wheel 14 one.Owing to be wound with rope 5 on this rope sheave 4, therefore the car 7 by rope 5 suspentions is driven and lifting.
When rope sheave 4 rotations, electromagnet 31 is energized and produces electromagnetic force, and as shown in Figure 2, electromagnet 31 is resisted the elastic force of retarding springs 30, attracts the leading section of each brake control lever 22.That is, a pair of brake control lever 22 is that rotate at the center with rest pin 21 respectively, and the brake shoe 24 that is fixed on the brake control lever 22 separates with the brake surface 25 of brake wheel 14.
On the other hand, when the energising cut off to electromagnet 31, electromagnetic force from electromagnet 31 disappears, brake control lever 22 is that rotate at the center with rest pin 21 respectively by the elastic force of retarding spring 30, make brake surface 25 press contacts of brake shoe 24 and brake wheel 14, brake wheel 14 and stop the rotation with the rope sheave 4 of brake wheel 14 one.
In addition, as can be seen from Figure 5, owing to the plane of rotation of brake shoe 24 from brake control lever 22 leaves to motor side housing 11 sides, therefore, unbalance load acts on brake shoe 24, and this load may directly feed through to brake surface 25.To this, between brake control lever 22 and brake shoe 24, insert packing ring 27 with certain play, be suppressed at the unbalance load on the brake surface 25 of brake shoe 24 by this packing ring 27.
As mentioned above, elevator hoist 3 according to present embodiment, be configured in rope sheave 4 sides owing to constitute a pair of brake control lever 22, brake shoe 24, retarding spring 30 and the electromagnet 31 of brake equipment, therefore can carry out the maintenance examination operation by directly visual to rope sheave 4 and each component parts that constitutes brake equipment from equidirectional, thereby can improve the operation of maintenance examination operation.
Especially, because towing machine 3 is fixed on the wall of hoistway 1, and make car 7 sides of rope sheave 4 towards lifting in hoistway 1, therefore, the operating personnel can carry out the maintenance examination operation in bigger space, need not use the space specially being provided with to the outstanding maintenance examination of the opposition side of car 7 with towing machine 3 opposed wall zones.
In addition, because packing ring 27 can slide by hemispheric relatively recess 26, therefore can suppress to impose on the unbalance load of the brake surface 25 of brake shoe 24, thereby make deceleration and stopping performance become stable from brake control lever 22.In addition, localized wear or inordinate wear with the brake shoe 24 of brake surface 25 moving contacts can be reduced, and the abrasion loss of the brake surface 25 of brake wheel 14 can be reduced.
In addition, because drg side body 12 is provided with and is used to cover the groove 15 of rope sheave 4 to prevent the retaining rope parts 32 of rope 5 releasing slots 15, therefore, at maintenance examination rope sheave 4 with when constituting each component parts of brake equipment, do not use specialized mirror and the special-purpose filler gauge can be from the gap between direct visual retaining rope parts 32 of equidirectional and the rope 5.
