Fig. 2 is the front view of wanting portion of the lift appliance of presentation graphs 1;
Fig. 3 is the block diagram of the main rope structure of presentation graphs 1;
Fig. 4 is the birds-eye view of the lift appliance of expression the invention process form 2;
Concrete example
Following with reference to description of drawings preferable example of the present invention.
Example 1:
Fig. 1 is the birds-eye view of the machine House-less type lift appliance of expression the invention process form 1; Fig. 2 is the front view of wanting portion of the lift appliance of presentation graphs 1.
Among the figure, in access trunk 1, be provided with a pair of cab guide rail 2 and a pair of weight guide 3.Cab 4 is by the 2 guiding liftings in access trunk 1 of cab guide rail.Counterweight 5 is by weight guide 3 guiding liftings in access trunk 1.
Cab 4 is provided with a plurality of guide blocks 6 that engage with cab guide rail 2.Counterweight 5 is provided with a plurality of guide plates 7 that engage with weight guide 3.
The upper end of guide rail 2,3 is equipped with supports platform 8.Support on the platform 8 actuating device (elevator) 9 to be housed.Actuating device 9 comprises electrical motor 10 and the drive pulley 11 of being rotated by this electrical motor 10.In addition, actuating device 9 has the direction of principal axis length slim profile littler than its diameter.And the axis that actuating device 9 is configured to drive pulley 11 extends along vertical.In addition, actuating device 9 is configured in the top in the bight of cab 4.
On drive pulley 11, be wound with the main rope 12 that constitutes by synthetic fiber rope.One end of main rope 12 is hung with cab 4.The other end of main rope 12 is hung with counterweight 5.That is, cab 4 and counterweight 5 are suspended in the access trunk 1 in 1: 1 sagging mode.
One end of main rope 12 is connected with the upper beam 4a of cab 4 with buffering material 14 through rope pin 13.The other end of main rope 12 is connected with the upper beam 5a of counterweight 5 with buffering material 16 through rope pin 15.
Support to support on the platform 8 to have main rope 12 is directed to the 1st direction conversion deflector wheel 17 of cab 4 and main rope 12 is changed deflector wheel 18 from the 2nd direction that actuating device 9 is directed to counterweight 5 from actuating device 9.The the 1st and the 2nd direction conversion deflector wheel 17,18 is configured to its axis of revolution along continuous straight runs and extends.In addition, the 1st and the 2nd direction conversion deflector wheel 17,18 is configured to cab 4 and counterweight 5 overlaps in vertical projection surface respectively.
In addition, the size of the above-below direction of the 1st and the 2nd direction conversion deflector wheel 17,18 and support platform 8 is less than the gauge of actuating device 9.And, the 1st and the 2nd direction conversion deflector wheel 17,18 and support platform 8 to be configured in the range of sizes of above-below direction of actuating device 9.
Fig. 3 is the block diagram of the main rope structure of presentation graphs 1.Among the figure, disposing the inside strand layer 24 that has a plurality of inner strands 22 and be configured in the filling strand 23 in the gap of 22 of these inner strands around the heart yearn 21.Each inner strand 22 is made of impregnation materials such as a plurality of aramid fibres and polyurethane.Filling strand 23 for example is made of polyamide.
The periphery of inner strand layer 24 disposes the outside strand layer 26 with a plurality of outside strands 25.Each outside strand 25 is made of impregnation materials such as a plurality of aramid fibres and polyurethane equally with inner strand 22.
The friction of disposing the abrasion that are used to avoid the strand 22,25 that strand 22, the 25 mutual frictions because of the fair lead of drive pulley 11 etc. cause between inner strand layer 24 and the outside strand layer 26 reduces covers coating 27.In addition, externally the peripheral part of strand layer 26 disposes protective case coating 28.
By a plurality of main ropes 12 cab 4 and counterweight 5 are suspended in the access trunk 1 with above-mentioned structure.In addition, in main rope 12, load is only transmitted by strand 22,25.And synthetic fiber rope is better than steel cable aspect great friction coefficient and the pliability having.
In this lift appliance, because, the axis that the upper level of actuating device 9 in access trunk 1 is configured to drive pulley 11 extends along vertical, cab 4 and counterweight 5 are that 1: 1 sagging mode is suspended in the access trunk 1, top in the access trunk 1 disposes the 1st and the 2nd direction conversion deflector wheel 17,18, and the formation machine is few, layout is simple so can make.
In addition, owing to adopt slim actuating device 9, the height dimension on the top in the access trunk 1 is reduced in the space that is provided with that can reduce actuating device 9.In addition, the occasion that increases at the capacity of actuating device 9 also can be in addition corresponding by increasing diameter.
And, owing to adopt the main rope 12, the 1 made by the good synthetic fiber rope that has great friction coefficient and pliability and the D/d (diameter of pulley/rope diameter) of the 2nd direction conversion deflector wheel 17,18 can be set at less.For example, the D/d of steel rope is more than 40, and synthetic fiber rope can reduce to about D/d=25.Therefore, can make the 1st and the 2nd direction conversion deflector wheel 17,18 above cab 4 and counterweight 5, overlap configuration and not increase the height dimension on the top in the access trunk 1, the energy simplified topology.
And, owing to actuating device 9 is configured in the top in the bight of cab 4, can in the abundant distance of guaranteeing to make main rope 12 between actuating device 9 and the 1st and the 2nd direction conversion deflector wheel 17,18, to be used to reverse, guarantee for drive pulley 11 sufficient winding angles.
Example 2:
Though the rear that is the cab 4 in access trunk 1 in example 1 disposes counterweight 5, as shown in Figure 4, the present invention also disposes the lift appliance of counterweight 5 applicable to the side of the cab in access trunk 14.
In addition, though in example 1,2, actuating device 9 and the 1st and the 2nd direction conversion deflector wheel the 17, the 18th through supporting that platform 8 is supported on the guide rail 2,3, also can be supported by the wall portion or the building of access trunk 1.
