The specific embodiment
Below, with reference to accompanying drawing preferable example of the present invention is described.
[example 1]
Fig. 1 is the constructional drawing of the lift appliance of expression the invention process form 1.Among the figure, dispose Machine Room 2 on the top of hoist trunk 1.In Machine Room 2, be provided with mechanical stage 3.On mechanical stage 3, carrying actuating device 4.The actuating device body 6 that actuating device 4 has drive pulley 5 and this drive pulley 5 is rotated.On mechanical stage 3, carrying revolvable deflector sheave 7 with the drive pulley 5 relative compartment of terrains of leaving.
On drive pulley 5 and deflector sheave 7, hang the main rope 8 of many (only representing 1 among Fig. 1) with semi-mounted (half lap scarf joint) formula ground volume.That is, the winding angle of main rope 8 relative drive pulley 5 and deflector sheave 7 is respectively less than 180 °.
Car 9 relative drive pulley 5 are played under the side of main rope 8.One end of main rope 8 is being connected with the upper beam 9a of car 9 by cage side rope anchor fitting 10.Play under the opposite side of counterweight 11 relative drive pulley 5 main ropes 8.The other end of main rope 8 is being connected with counterweight 11 by counterweight side rope anchor fitting 12.Car 9 and counterweight 11 utilize the propulsive effort of actuating device 4 to carry out lifting in hoist trunk 1.
On the bottom of hoist trunk 1 (melt pit), car buffer 13 and counterweight buffer 14 are being set, and this two energy disperser is used to relax downwards when making car 9 and counterweight 11 exceed the occasion that normal lifting travel ground descends because of certain reason and the impact of the collision of the bottom of hoist trunk 1.On counterweight buffer 14, be provided with the detector switch 15 that the action of giving to counterweight buffer 14 detects.
On the smallpox board of hoist trunk 1, be provided with as the cigarette perceptron 16 that cigarette is carried out the fire perceptron of perception.On mechanical stage 3, be provided with the rope brake device 17 that stops car 9 liftings that cause by actuating device 5 by clamping main rope 8.Rope brake device 17 is than drive pulley 5 more close counterweight 11 side clamping main ropes 8.
Rope brake device 17 is controlled by control setup 18.To import to control setup 18 from the motion detection signal of detector switch 15 with from the fire perceptual signal of cigarette perceptron 16.That is, rope brake device 17 is will be from the motion detection signal of detector switch 15 to control setup 18 input backs and will from the fire perceptual signal of cigarette perceptron 16 after control setup 8 inputs main rope 8 be braked clampingly.
Again, control setup 18 when input fire perceptual signal, carries out braking maneuver to rope brake device 17 behind the controlled operation when implementing fire.
Then, the cutaway view of Fig. 2 after to be expression with main rope 8 with the contact portion of the main rope 8 of the drive pulley 5 of Fig. 1 amplify.Among the figure, on drive pulley 5, be provided with many rope groove 5a that main rope 8 is inserted.The section shape of the bottom surface of rope groove 5a is circular-arc (semicircle shape).That is, on the bottom of rope groove 5a, be not provided with grooving down.
Each main rope 8 has: core rope 21; Overlayed on the resin coremaking rope lining body 22 on core rope 21 peripheries; Be configured in the skin 23 on core rope lining body 22 peripheries; And the outer lining of the resin system of lining on outer 23 peripheries body 24.
Core rope 21 has many stranded core twisted cables 25 mutually.Each core twisted cable 25 has the core single line 26 of many stranded mutually steels.
Outer 23 have many stranded outer twisted cables 27 on the periphery of core rope lining body 22.Each outer twisted cable 27 has the outer single line 28 of many mutually stranded steels.
Core rope lining body 22 for example is made of poly-vinyl resin.Outer lining body 24 is that rub resin material, for example polyamine fat resin of height 0.2 or more constitutes by friction coefficient.
In such lift appliance, because the skin that is positioned at the outermost layer of main rope 8 and contacts with rope groove 5a lining body 24 utilizes high friction resin material to constitute, even event hangs over drive pulley 5 and deflector sheave 7 on semi-trailer ground volume main rope 8 and the section shape of the bottom of rope groove 5a is circular-arc, also can guarantee enough towabilitys.Again, owing to grooving down can be set in the bottom of rope groove 5a, so can prevent that grooving causes damage under outer lining body 24 quilts.
Again,, compare, can will act on axle load on the actuating device body 6 and make only about half ofly, can realize the miniaturization of actuating device 4 with the occasion of full extension (full overlap joint) formula in that main rope 8 is hung over occasion on drive pulley 5 and the deflector sheave 7 with semi-trailer volume.
Here, utilize following formula that towability is calculated.
Towability=e
μ K2 θ
μ: friction coefficient
K
2: according to the coefficient that produces with the contact condition (being generally the shape of groove) of rope groove
θ: main rope is to the winding angle of rope sheave
Hang on the drive pulley at the steel rope that will not have outer lining body with fully-trailed volume, be provided with the occasion of grooving down in the rope groove, become: coefficientoffriction=0.1, COEFFICIENT K
2=1.38 (the incision angle is 50o), winding angle θ=330 °.
Therefore, towability=e
(0.1 * 1.38 * 330/180 * π)=2.21.
In order in the lift appliance of example 1, to guarantee the friction coefficient that the towability equal with it is required, try to achieve with following formula:
Coefficientoffriction=1n (2.21)/(K
2* θ)
＝1n(2.21)/(1.2×150/180×π)＝0.25
Wherein, COEFFICIENT K
2Not=1.2 (not having grooving down),
Winding angle=150 ° (330-180=150 °).
Therefore, if the friction coefficient that skin is covered between body 24 and the drive pulley 5 makes more than 0.2, enough towabilitys are guaranteed in then big activation.If the friction coefficient between just outer lining body 24 and the drive pulley 5 makes more than 0.25, then can guarantee towability more reliably again.
Again, in example 1, will be from the motion detection signal of detector switch 15 during to control setup 18 inputs and since utilize rope brake device 17 in counterweight 11 sides with main rope 8 clampings braking, so utilize rope brake device 17 to support to the deadweight of the main rope 8 of counterweight 11 sides.Owing to utilize 14 pairs of counterweights 11 of counterweight buffer to support,, the tractive force on the drive pulley 5 is suitably reduced so the load of counterweight 11 sides reduces again.Therefore, when counterweight 11 is collided with counterweight buffer 14, can make drive pulley 5 idle running, and car 9 is stopped reposefully.
Such system can also be applicable to that use does not have in the lift appliance of steel rope of outer lining body, and especially the high-lift lift appliance from great to main rope is an actv..
Again, will be after control setup 18 inputs from the fire perceptual signal of cigarette perceptron 16, owing to can utilize rope brake device 17 with main rope 8 clampings, braking, so skin lining body 24 because of the heat of fire just in case the occasion that tractive force reduces during fusion, can prevent that also main rope 8 from carrying out moving of car 9 that slippage causes relative to drive pulley 5.
Again, control setup 18, when input fire perceptual signal, owing to when implementing fire, behind the controlled operation rope brake device 17 is carried out braking maneuver, so can the passenger in the car 9 successfully be taken refuge.
In addition, the fire perceptron is not limited to cigarette perceptron 16, for example also can be the perceptron of other kinds such as hot perceptron.
Again, the fire perceptron both can be special-purpose and be configured in perceptron in the hoist trunk 1 for lift appliance, also can be configured in building one side for example take advantage of perceptron on the Room etc.
[example 2]
Then, Fig. 3 is the drive pulley of lift appliance of expression the invention process form 2 and the lateral plan of deflector sheave and main rope, and Fig. 4 is the drive pulley of presentation graphs 3 and the birds-eye view of deflector sheave and main rope.Drive pulley when again, Fig. 3 and Fig. 4 are illustrated in counterweight arrival counterweight buffer and the relation of deflector sheave and main rope.
Among the figure, the resinous outer lining body 32 of the outer periderm of main rope 31 is being covered.Outer lining body 32, have low friction lining portion 34, it is positioned at by the height friction lining portion 33 of the part of drive pulley 5 when car 9 and counterweight 11 (with reference to Fig. 1) are carried out the lifting of common lifting travel and surpasses common lifting travel ground in counterweight 11 and is positioned at and drive pulley 5 contact portions when mobile downwards.
In other words, main rope 31 has when car 9 carries out the lifting of common lifting travel with counterweight 11 section 1 by drive pulley 5 and surpasses the part 2 that common lifting travel ground contacts with drive pulley 5 when mobile downwards in counterweight 11.And, the high friction of outer periderm lining portion 33 linings of section 1,34 linings of the low friction of the outer periderm of part 2 lining portion.
High friction lining portion 33 is made of the height friction resin of for example polyamine fat etc.As mentioned above, if the friction coefficient that height is rubbed between lining portion 33 and the drive pulley 5 makes more than 0.2, enough towabilitys are guaranteed in then big activation.If the friction coefficient that height is rubbed between lining portion 33 and the drive pulley 5 makes more than 0.25, then can guarantee towability more reliably again.
Again, the low lining portion 34 that rubs is by constituting than constituting high little resin material, for example polythene material, nylon, silicon, polypropylene or the polyvinylchloride etc. of resin material friction coefficient that rub lining portion 33.Again, height is rubbed lining portion 33 with low friction lining portion 34 go up different color mutually.Other structure and example 1 are same.
In such lift appliance, when car 9 and counterweight 11 are carried out the lifting of common lifting travel, because high friction lining portion 33 contacts with drive pulley 5, so can similarly obtain enough towabilitys with example 1.
Again, after car is moved upward with surpassing common lifting travel, promptly after counterweight 11 moves downwards above common lifting travel ground, low friction lining portion 34 contacts with drive pulley 5, the reduction when common of the friction force between drive pulley 5 and main rope 31.
Therefore, after counterweight 11 moved downwards above common lifting travel, tractive force suitably reduced, and drive pulley 5 becomes idle running easily, the required torque of actuating device 4 in the time of reducing to dally.
Because the low lining portion 34 that rubs is set, also can omit the detector switch 15 in the example 1 on skin lining body 34 again.
Again, since with height rub lining portion 33 and low friction lining portion 34 go up mutual different color, so can be easily when mounted or can judge the direction of main rope 31 easily during the transposing of main rope 31, and after counterweight 11 surpasses common lifting travel ground and moves downwards whether confirm contacting with drive pulley 5 to hanging down the lining portion 34 of rubbing.
In addition, in example 2, the low friction of utilization lining portion 34 is covered the periphery of the part 2 of main rope 31, as long as but can make the friction coefficient of part 2 periphery littler than the friction coefficient of the high lining portion that rubs, periphery that also can resin-coated part 2 is exposed twisted cable.
[example 3]
Then, Fig. 5 is the constructional drawing of the lift appliance of expression the invention process form 3.Among the figure, on mechanical stage 3, be provided with the rope brake device 19 that stops by 8 pairs of counterweight 11 liftings that cause because of actuating device 5 of clamping main rope.Rope brake device 19 is at the position clamping main rope 8 than drive pulley 5 more close car 9 sides.On car buffer 13, be provided with the detector switch 20 that the action of giving to car buffer 13 detects.
Rope brake device 19 is controlled by control setup 18.To import to control setup 18 from the motion detection signal of detector switch 20.That is, rope brake device 17 will be from the motion detection signal of detector switch 15 when control setup 18 inputs, with main rope 8 clampings, braking.Other structure and action are same with example 1.
In such lift appliance, when car 9 collides with car buffer 13, owing to utilize rope brake device 17 with main rope 8 clampings, thus drive pulley 5 is dallied, and counterweight 11 is stopped reposefully.Thus, can prevent that the smallpox board of counterweight 11 and hoist trunk 1 from colliding, and can prevent the damage of equipment.
In addition, in example 3,, also can only use rope brake device 19, also can utilize the brake equipment of other pattern to prevent car 9 upper punches though use rope brake device 17,19 together.
Again, in example 1～3, the cross-section structure of the main rope of the inboard of outer lining body is not limited to structure shown in Figure 2, can carry out various changes for the configuration of the number of plies and twisted cable etc.
