The specific embodiment

In order to illustrate in greater detail the present invention, be described with reference to the accompanying drawings.

[example 1]

Fig. 1, Fig. 2 are the figure of configuration example of lift appliance of the machine House-less type of expression example 1 of the present invention, Fig. 1 is the birds-eye view of lift appliance of looking down from the top, Fig. 2 is a part elevation view of seeing lift appliance from horizontal direction, is respectively the concept map of expression lift appliance main portion.

Among the figure, in hoist trunk 1, dispose a pair of master (car with) guide rail 2 of guide rail bracket 4 supporting on the wall that is installed in hoist trunk 1 and another to secondary (counterweight with) guide rail 3.Car 5 is led and lifting in hoist trunk 1 by main guide rail 2, and counterweight 7 is by secondary guide rail 3 guiding and liftings in hoist trunk 1.

On car 5, just like the gangway door 5a shown in the birds-eye view of Fig. 1, main guide rail 2 is configured in and the come in and go out two sides side of car of actinal surface quadrature of car in the hoist trunk front portion, and secondary guide rail 3 is configured in and car gangway opposing backside surface side.Again, on car 5, be provided with a plurality of guide tiles 8 that engage with main guide rail 2, on counterweight 7, be provided with a plurality of guide tiles 9 that engage with secondary guide rail 3.The supporting station carriage 31 that has mounting support platform 30 usefulness in the upper end separately of main guide rail 2 and secondary guide rail 3, supporting station 30 is installed on this supporting station carriage 31 by vibrationproof member 32.Supporting station 30, also can be directly installed on the supporting station carriage 31, but for prevent to make vibration that actuating device 10 takes place from main guide rail 2 and secondary guide rail 3 by guide rail bracket 4 by lifting channel wall portion to the building transmission, be preferably in and supporting station carriage 31 between accompany vibrationproof member 32 ground and use.

Volume hangs with Main cable of elevator 20 and constitutes S. A. to be become the drive pulley 12 of vertical and has the actuating device 10 that drive pulley 12 is rotated drive electric motor 11, and it is that the axial thickness of rotation is formed is less slim that its profile is compared with diametric size.Breast wheel 14, be configured to drive pulley 12 similarly S. A. be vertical.Actuating device 10, breast wheel 14 carry on supporting station 30, and actuating device 10 is configured in the top of the corner portion of car 5, and breast wheel 14 disposes with the distance ground that actuating device 10 separates regulation.That is to say that actuating device 10 is configured in the corner near hoist trunk 1, breast wheel 14 is configured in another corner near hoist trunk 1.Additionally describe again, in Fig. 1, actuating device 10, being configured in the last optimum position of traction (in that the main rope volume is hung in the process of pulley class, can not produce the position of main rope cross interference) is the corner, close rear portion of hoist trunk.

Again, in this example, represented that breast wheel 14 and actuating device 10 similarly carry the example on supporting station 30, but breast wheel 14 can carry also on the supporting station that is provided with dividually with supporting station 30.

Then, main rope 20 has 2 paths arranged side by side that are made of independently the 1st rope 21 and the 2nd rope 22, and the 1st rope the 21, the 2nd rope 22 is made of the group of the many unit ropes that constitute respectively.

Pars intermedia with main rope 20 of the 1st rope the 21, the 2nd rope 22 after quilt is rolled up and hung on the drive pulley 12, is hung to breast wheel 14 volumes, and volume hangs on the drive pulley 12 again.One end of main rope 20, by counterweight deflector sheave 18, main rope 20 is changed to the vertical travel direction from horizontal direction, until counterweight 7 from drive pulley 12.That is to say that rolling up extension, hanging, use deflector sheave 18 between counterweight 7 through counterweight to drive pulley 12 volumes again to breast wheel 14 from drive pulley 12, the 1st rope 21 and the 2nd rope 22 form main rope 20 abreast.

And, the 1st rope the 21, the 2nd rope 22, all an end is being connected with the upper beam 29 of counterweight 7 with helical spring buffer component 27 by using rope shackle 26.

Again, the other end of main rope 20, i.e. 5 the other end from drive pulley 12 to car, the 1st rope 21 and the 2nd rope 22 are separated from each other, respectively by the 1st car deflector sheave the 16, the 2nd car deflector sheave 17, the 1st rope the 21, the 2nd rope 22 is changed to the vertical travel direction from horizontal direction, and is connected with the established part of car 5.On this other end, the 1st rope the 21, the 2nd rope 22, by using rope shackle 24 and helical spring buffer component 25, the locational 2 place carriage bracket 6 relative with the center of gravity that clips car 5 that is arranged on car 5 bottoms connect respectively.

Thus, do not need as in the past the example on the top of car 5 hanging part is set, so can make the cooresponding space, hanging part of the size reduction up and down and the car 5 of hoist trunk 1.In addition, relatively in 1 supporting in the past car 5 tops, in the present invention,,, can also make car 5 lightweights and reduce cost of manufacture so can reduce the intensity of the structural elements on car 5 tops owing to become 2 supportings in the bottom of car 5.

Again, in this example, example as the best, car 5, be bottom-supported with car 5, but as long as support with 2 places of the top below of car 5, owing to the size up and down that can dwindle hoist trunk 1, if so the support relative side that is car 5, bearing position also can be in any position.

Then, as mentioned above, in this example, as the car deflector sheave, 22 corresponding with the 1st rope 21 and the 2nd rope, respectively have the 1st car with deflector sheave 16 and the 2nd car with deflector sheave 17, and be configured to disconnected from each other and the overlapping state of at least a portion and car 5 on the vertical projection surface of hoist trunk 1.Again, the 1st car with deflector sheave 17, lays respectively at the top of rope shackle 24 with deflector sheave the 16, the 2nd car.That is to say, the 1st car deflector sheave the 16, the 2nd car deflector sheave 17, be configured to its major part state overlapping on vertical projection surface, therefore, do not need be configured to the distance of car 5 and lifting channel wall is obtained big (not needing to enlarge the plane of hoist trunk 1) with car 5.

Counterweight is with deflector sheave 18, is configured to the overlapping state of on the vertical projection surface of hoist trunk 1 at least a portion and counterweight 7.Again, the 1st car is set on the supporting station 30 with deflector sheave 18 with deflector sheave 17, counterweight with deflector sheave the 16, the 2nd car.

Here, breast wheel 14 is configured to be sandwiched in from drive pulley 12 to the 1st cars and uses between the main rope 20 of deflector sheave 18 with the main rope 20 (the 1st rope 21) of deflector sheave 16 and from drive pulley 12 to counterweight.

That is to say, for drive pulley 12, breast wheel the 14, the 1st car deflector sheave the 16, the 2nd car deflector sheave 17, counterweight deflector sheave 18, in the process of pressing the sequential volume extension main rope 20 that constitutes them, can be configured to make main rope 20 to intersect and the situation of generation interference.Again, when hanging car 5 with car 5 relative sides, preferably on the relative position of the center of gravity that clips car 5, suspend in midair, in such occasion, Fig. 1 sees hoist trunk 1 from vertical like that, and the hanging part at two places of car 5 is near the side wall surface of substantial middle of hoist trunk 1 (main guide rail 2 near).Therefore, dispose breast wheel 14 as described above, actuating device 10, breast wheel the 14, the 1st car are provided with equipment with deflector sheave 17, counterweight with deflector sheave 18 such hoist trunk tops that are set on the supporting station 30 with deflector sheave the 16, the 2nd car, see hoist trunk 1 from vertical, use the line of deflector sheave 17 as benchmark with connecting the 1st car with deflector sheave 16 and the 2nd car, can be housed in the one-sided of hoist trunk 1, can realize making the top save spaceization of hoist trunk 1, the densification of supporting station 30, and guarantee service clearance.

Again, the configuration of above-mentioned explanation is the example in the configuration place of best breast wheel 14, and according to the situation of the floor plan of lift appliance, breast wheel 14, also can be configured to be sandwiched in and use the state of (specifically, using between the main rope 20 (the 2nd rope 22) of deflector sheave 17 with the main rope 20 (the 1st rope 21) of deflector sheave 16 and from drive pulley 12 to the 2nd cars) between the main rope 20 of deflector sheave 18 with the main rope 20 (the 2nd rope 22) of deflector sheave 17 and from drive pulley 12 to counterweight from drive pulley 12 to the 1st cars from drive pulley 12 to the 2nd cars.

Again, in this lift appliance, the control panel 33 and the governor 34 that are used for the lifting of car 5 is controlled are installed in supporting station 30, these control panels 33, governor 34 and breast wheel 14 are configured to be housed in actuating device the 10, the 1st car and use in the scope of certain 1 the maximum height size in the deflector sheave 18 with deflector sheave 17, counterweight with deflector sheave the 16, the 2nd car.In Fig. 2, be configured to be housed in the width up and down of actuating device 10 again.

Fig. 3 is the shape in the past of groove of the expression volume drive pulley that hangs with main rope 20 and the cutaway view of shape of the present invention.

In Fig. 3, the drive pulley 13 of shape in the past is provided with the groove that is known as special following grooving in the part of main rope 23 contacts.Nipping to this groove by main rope 23 to increase friction force, but exists the wearing and tearing because of main rope 23 to increase the shortcoming that makes the lost of life.Therefore, the drive pulley 12 of this example has the U-lag that volume is hung main rope 20, and makes the diameter of the bottom semicircular portion of this U-lag form the diameter approximate with the diameter of main rope 20.Therefore since the area of contact of drive pulley 12 and main rope 20 is made bigger, so can reduction face pressure, also be favourable aspect the life-span of main rope 20.

As mentioned above, in this example, after hanging over main rope 20 volumes on the drive pulley 12, by hanging to breast wheel 14 volumes, volume hangs on the drive pulley 12 again, and the volume that can increase the contact amount of 20 pairs of drive pulley 12 of expression main rope is hung angle, just obtains the tractive force of regulation easily.

Thus, from conduct main rope 23 in the past, use utilizes the special main rope of the height friction of syntheticfibres, also utilize the combination of the drive pulley 13 be provided with special following grooving to improve the mode of tractive force, by general main rope 20 with steel and the U-lag of rolling up this main rope 20 of extension, with the combination of the diameter of the bottom semicircular portion of this U-lag with the approximate formed drive pulley 12 of diameter of the diameter of main rope 20, can obtain required tractive force, main rope 20 high lifeization can be made, the cost when making maintenance can also be reduced.

Again, in this example, actuating device 10 is configured in the top of the corner portion of car 5, the diameter of breast wheel 14, generally form the diameter identical or form its degree of 90% with the diameter of drive pulley 12, with actuating device 10 separate regulation the distance be configured.That is to say, drive pulley 12, relative other pulley (breast wheel the 14, the 1st car deflector sheave the 16, the 2nd car deflector sheave 17, counterweight deflector sheave 18), be configured in the corner of close hoist trunk 1 for the purpose of leaving as far as possible, so can guarantee for make drive pulley 12 and with another axial different pulley of pulley between the main rope 20 that produces reverse the enough distances that obtain relaxing, and can guarantee enough winding angles of relative drive pulley 12.

Again, in this example, except control panel 33, governor 34 and breast wheel 14, also have the 1st car deflector sheave the 16, the 2nd car deflector sheave 17 and counterweight deflector sheave 18, be configured to be housed in the state in the scope of maximum height size of actuating device 10, owing to be configured in similarly in the above-mentioned scope for supporting station 30, so can further suppress the size up and down on the top of hoist trunk 1.Again, the expression maximum height be not limited to actuating device 10, for example, also can be the 1st car with deflector sheave the 16, the 2nd car with deflector sheave 17 and counterweight wantonly 1 with deflector sheave 18.

Again, the present invention uses general main rope can easily guarantee tractive force as mentioned above, but also can adopt the main rope of the thin diameter of high tension type to replace general main rope and further improve towability.Here, on the rules, the relation of the diameter of diameter of pulley and main rope, owing to make diameter of pulley/main rope diameter 〉=40, by use the high tension type, than the thin main rope of diameter in the past, just can make drive pulley 12, breast wheel the 14, the 1st car with deflector sheave the 16, the 2nd car with deflector sheave 17, counterweight with the such pulley class minor diameterization of deflector sheave 18, can also make actuating device 10 minor diameterizations, can further improve the save spaceization on hoist trunk 1 top.

[example 2]

Fig. 4 is that expression the present invention is the birds-eye view of configuration example of lift appliance of the machine House-less type of example 2.

In example 1, the rear of the car 5 in hoist trunk 1 disposes counterweight 7, and as shown in Figure 4, counterweight 7 is configured in the side of the car 5 in the hoist trunk 1.That is to say, see counterweight 7 from the gangway door 5a side of car 5, owing to make a side's of car 5 side carry out lifting, so see that from the entrance side of hoist trunk secondary guide rail 3 also is configured in hoist trunk side (this occasion is left surface).Corresponding with the change of such configuration, the shape of supporting station 30 also changes.But, other structure and action thereof, substantially the same with example 1, so identical or considerable part are put on identical symbol and are omitted its explanation.Again, in this example 2, breast wheel 14 also is configured to be sandwiched in from drive pulley 12 to the 1st cars and uses the main rope 20 (the 1st rope 21) of deflector sheave 16 and the state between the usefulness main rope 20 of deflector sheave 18 from drive pulley 12 to counterweight.

In this example, after hanging over main rope 20 volumes on the drive pulley 12, to breast wheel 14 volume hang, volume hangs on the drive pulley 12 again, also can increase the winding angle of the contact amount of 20 pairs of drive pulley 12 of expression main rope, just can easily obtain the tractive force of stipulating.

Thus, from conduct main rope 23 in the past, use utilizes the special main rope of the height friction of syntheticfibres, also utilize the combination of the drive pulley 13 be provided with special following grooving to improve the mode of tractive force, general main rope 20 by having steel and volume hang with the U-lag of this main rope 20, with the combination of the diameter of the bottom semicircular portion of this U-lag with the approximate formed drive pulley 12 of diameter of the diameter of main rope 20, can obtain equal tractive force, main rope 20 high lifeization can be made, the cost when making maintenance can also be reduced.

Again, owing to do not need picture on the top of car 5 hanging part to be set routine in the past, so can be with the cooresponding space, hanging part of the size reduction up and down and the car 5 of hoist trunk 1.In addition, relatively in 1 supporting in the past car 5 tops, in the present invention,,, can also make car 5 lightweights and reduce cost of manufacture so can reduce the intensity of the structural elements on car 5 tops owing to become 2 supportings in the bottom of car 5.

Other can play and the same effect that is obtained with example 1.

[example 3]
