Description
The invention relates to a kind of jacking system of elevator, particularly about jacking system being seated in the machine room of elevator lifting bottom, lift well has a kind of being used for that jacking system is fastened to improvement parts and a kind of improved elevator drum wheel on the hoistway wall.
Fig. 1 represents a kind of traditional elevator jacking system.This device is mounted in the machine room near the bottom of lift well.As shown in the figure, a machine room 2 is arranged in the floor indicator 1, and the pit 1a of 2 a little higher than lift wells 1 of machine room.Jacking system is installed in the machine room 2, comprising elevator 4, be used to install the base 3 on the floor 2a that is secured to machine room 2 of elevator, and the parts that comprise label 8 to 11 representatives, they are to be used for making an end face of base 3 to be close to than machine room 2 wall of the pit 1a of lower slightly.It is unshowned by motor-driven gear reduction that elevator 4 comprises that a unshowned motor and overlaps, and be installed in the elevator drum wheel 4a on the gear reduction shaft extension.Have many main push-towing rope ropes to reel on it on the drum 4a, main push-towing rope rope 7 is connected on the framework 5a of lift car 5 after through the leading sheave 6 that is installed in the elevator top.Car is played by main push-towing rope rope 7 and does dipping and heaving along lift well.
Clearer expressing in Fig. 3: be provided with many horizontal beam 3a on the base 3, horizontal beam is fastened on the floor 2a of machine room 2 with the holding-down bolt that does not illustrate, at the same time, horizontal beam 3a end face is fastened on the wall of lift well with the parts that are adjacent to of above-mentioned label 8 to 11.Metal binding of label 8 expressions, its fixed part 9 bolt ups are to wall 1a, and fixed parts 9 comprises nut and holding-down bolt or analogue.The top 8a of binding 8 is bent in the elevator 1 with the direction that deviates from wall, and is fastened on the base 3 with the fixed parts 11 that comprises nut and screw rod or analogue.Screw rod is that bolt is come in the hole of passing on the top 8a of hole on the beam 3a and binding 8.Label 10 expression metal gusset pieces, its bottom is soldered on the end face of binding 8, and with comprising that the fixed parts of screw rod and nut or analogue is fastened to its top on the end face of base 3, the base 3 that elevator 4 is installed is secured on the binding 8 simultaneously.Binding 8 itself is then being pasted on the wall of the pit 1a that is fastened to the elevator 1 that is lower than machine room 2 slightly.
Be used for that the device that elevator 3 is fastened on the pit 1a wall of elevator 1 is had following shortcoming: at first, because the top of gusset piece 10 is fastened on the end face of base with bolt, the operational space of serviceable tool when enough intensity and hold-down bolt are provided then, the end face of base 3 must put in length A in the elevator.In this class jacking system, length A can not reduce a lot, and therefore, it is very difficult in narrow lift well this class jacking system being installed.Another problem is will be with a large amount of fixed partss, and this is that to be connected on the binding 8 on these fixed partss institute to base 3 requisite.In addition, as shown in Figure 3, the width A1 of base 3 must equal the width of binding 8 just.For binding 8 and beam 3a are connected mutually rightly, the spacing A2 in the hole on the top 8a of binding 8 must just in time equal to open in order to fasten limiting-members 11 spacing in corresponding hole on beam 3a.Thereby plate 8 and base 3 require cooresponding particularity during fabrication, and base 3 is fastened on the binding 8 is difficult.
More serious problem is: on the wall for the well 1a that base 3 is fastened to lift well 1, use the single binding of bulk.This problem shows in Fig. 4, and Fig. 4 is the section drawing that the elevator among Fig. 3 cuts along II-II.The wall of the pit 1a of lift well 1 is normally made by cement concrete, thereby not very smooth under many circumstances, like this, wide binding 8 across whole base width just can not be attached on the wall of well 1a well, so just have only several places can support binding 8, and in fact the other parts of binding are not to be attached on the wall of pit 1a.In this case, for binding 8 firmly being fastened on the wall of pit 1a, the holding-down bolt of fixed parts 9 is inevitable by very tightly last, and tightens up degree than being critical manyly when whole binding 8 can be attached on the wall well.Like this, along with being tightened up of holding-down bolt, binding 8 will be bent, and binding will trend towards holding-down bolt is extracted from wall for the power of resisting crooked deformation.Thereby from the viewpoint of structural strength, this method that is used for base 3 is fastened on the pit 1a wall is undesirable, and has potential danger.Because under the effect of the power that acts on binding, the bolt in the fixed parts 9 may be extracted from the wall of pit 1a.
Existing another problem of this quasi-tradition elevator will illustrate below, simultaneously with reference to figure 5 to Fig. 7.Fig. 5 is the birds-eye view of the traditional jacking system among Fig. 1, the wherein more detailed drum 4a that represents elevator 4.Can see that two covers be used to reel the groove 4b and the 4c of hawser are arranged on the surface of drum 4a, groove is to be arranged to central spiral by the relative two ends of drum.The first cover cable laying rope-race groove 4b is reeled along groove by article one main push-towing rope rope 7a, and same, the about groove 4c of the second cover cable laying rope is reeled along groove by second main push-towing rope rope 7b, and every main push- towing rope rope 7a and 7b are connected on the framework 5a of lift car 5 by aforesaid leading sheave 6.Label 12 expression is provided with the platform of each layer on the building of elevator 1.
As shown in Figure 6, Fig. 6 is that elevator among Fig. 5 is along the birds-eye view of III-III line.Because insufficient space, directly over the leading sheave 6 general central authorities that directly do not place on the drum 4a length, but vertically hold mobile place to one of drum 4a, therefore, angle between the longitudinal axis of drum 4a and each main push- towing rope rope 7a and 7b is unequal, this names a person for a particular job and illustrates in Fig. 7, and Fig. 7 is the scheme drawing of the geometric relationship between the leading sheave 6 of elevator among expression drum 4a and Fig. 5.In this figure, L
0Be the distance of the axis of pulley 6 to the surface of drum 4a, Q
1Be the surface of drum 4a and the angle between article one main push-towing rope rope 7a, Q
2Be the surface of drum 4a and the angle between the second main push-towing rope rope 4b.Because pulley 6 is not the top Q that is positioned at the centre of drum 4a
1With Q
2Be unequal, so between drum 4a and pulley 6, be unequal along main push-towing rope rope 7a and the measured distance of 7b respectively.These two distances are respectively: L
0/ sin(Q
1) and L
0/ sin(Q
2), like this, because this two length difference, the tension force that acts on these two main push-towing rope ropes is unbalanced.This occurs over burdening with respect to second main push-towing rope rope 7b on article one main push-towing rope rope 7a, perhaps react as the same, and this depends on the residing position of main push-towing rope rope on the drum 4a.This tension imbalance on the main push-towing rope rope will shorten their life-span, then just need be with the thicker hawser of hawser used when adding same load on two main push-towing rope ropes, even the destruction that may cause the main push-towing rope rope.
Another problem that this quasi-tradition lift appliance exists is about the main push-towing rope rope being fixed to the parts on the drum.This problem is illustrated in Fig. 8 to Figure 10.Fig. 8 is the front elevation of an end on the drum length of the represented the sort of elevator of Fig. 5.Fig. 9 is the partial cross section view of the same drum that cuts along IV-IV among Fig. 8.Figure 10 is the section drawing of the drum that cuts along V-V in the presentation graphs 9.As shown in these figures, main push-towing rope rope 7a firmly is fixed on its end with a columniform git 14.Git 14 is loaded in the hole 4g on the drum 4a wall, and hole 4g links with a conductor rope groove 15 that also is located on the drum 4a wall.The width of groove 15a be a bit larger tham main push-towing rope rope 7a diameter and less than the diameter of git 14.When git 14 by among the embedded hole 4g fully the time, the termination of main push-towing rope rope 7a touches on the inside face of groove 15a, when applying tension force on main push-towing rope rope 7a, the end face of git 14 just firmly is pressed onto on the bottom surface of conductor rope groove 15a.Another main push-towing rope rope 7b also uses the same method and is connected on the drum 4a.
When main push- towing rope rope 7a and 7b are wound on drum 4a when going up with being tauted, be out of question in this way.Yet, if when the stroke that lift car 5 arrives it is held to the greatest extent, and when touching on the energy disperser of not expressing at the pit 1a place that is placed on elevator 1 usually, it is loose that the main push-towing rope rope will become, and just do not have power to prevent to come off out the hole 4g of git 14 from drum 4a.Therefore, before lift car 5 is promoted once more along elevator 1, just must check whether git 14 firmly is stuck in drum 4a the inside really.So on the angle of safety, this parts as fastening main push-towing rope end portion are imperfect.
Thereby, as discussed above, there is an a kind of improvement elevator hoist apparatus of needs, it can be anchored in the elevator that it installs better, and, need a safer drum.
The objective of the invention is to overcome the above-mentioned shortcoming of traditional elevator hoist apparatus, simultaneously, provide a kind of even when the wall that is used to be fastened to elevator be not smooth time marquis, also can more safely be fastened to the elevator hoist apparatus on the hoistway wall.
Another object of the present invention provides a kind of elevator hoist apparatus that can be easily mounted in the elevator.
Further purpose of the present invention provides a kind ofly less gives prominence to elevator hoist apparatus in elevator than conventional elevator.
Another object of the present invention provides a kind of usefulness parts seldom just can be fastened to elevator hoist apparatus on the hoistway wall to it.
It is a kind of through improved elevator drum wheel that the present invention has a purpose to provide, and it makes the load of lift car equally be born by several main push-towing rope ropes of elevator.
A further object of the invention provides a kind of, uses a kind ofly through improved, and the parts of safety come an end of elevator main rope is fastened to elevator hoist apparatus on the drum of this class device.
In the present invention, it is porose to be used for that the base of jacking system is fastened on its top of binding on the hoistway wall cloth.An end face of jacking system base is by these holes and be fastened to there.In this method, base can be fastened on the binding at an easy rate, simultaneously also reduce base and extend into length in the elevator, binding is divided into the binding that is parallel to each other of many broads on its Width, because these bindings are narrower, even when the air spots of hoistway wall is smooth, they can both firmly be fastened on the hoistway wall, the present invention also comprises a drum that has improved, it have two spirally with same direction from drum one end to the cable ditch that be parallel to each other of other end ground cloth on the drum cylinder.Because the main push-towing rope rope is to be wound in parallel to each other on the drum, their length always equates, thereby the load of bearing for the support lift car equates.In addition, the present invention also comprise one be used for an end of main rope be fixed on the drum through improved parts, drum use with receive main push-towing rope rope one end on the clevis bolt that matches of cylindrical git.And the U-shaped screw rod is bolted on the end plate that is fastened on the drum end.Because git blocked tightly by clevis bolt, just need not be concerned about whether be applied with tension force on the main push-towing rope rope, like this, both made when the main push-towing rope rope becomes loose, can there be danger that an end of main push-towing rope rope is deviate from from drum yet.
Therefore, the invention relates to an elevator hoist apparatus, this jacking system is to be used on the pit of elevator this elevator of a machine room is arranged, and opens wide between this machine room and the elevator.This jacking system comprises: an elevator; The base that elevator securely is installed; Be used for base is fastened to tabular secure component on the hoistway wall that is lower than machine room slightly.The upper end of this secure component has a base fastener hole, and this secure component is secured on the hoistway wall that is lower than the machine room place slightly, and an end of base passes these base fastener holes and firmly is connected on this secure component simultaneously.

The explanation of some optimum implementation
Below will to of the present invention several preferably embodiment illustrated, simultaneously with reference to figures 11 to Figure 22.
Figure 11 to Figure 13 expresses first kind of embodiment of the present invention, is used for illustrating elevator of the present invention.As the traditional jacking system shown in Fig. 1, the said jacking system of the present invention comprises: an elevator 20, wherein be provided with an electrical motor that does not illustrate and one the cover do not illustrate by electric motor driven gear reduction; Be installed in the drum 21 of the shaft extension end of gear reduction; The base 3 that includes the beam 3a on a plurality of floor 2a that are secured to machine room 2; And be used for an end face of base 3 securely is fastened to some parts on the wall of pit 1a of the elevator 1 that is lower than machine room 2 slightly.This parts that jacking system firmly is fastened on the hoistway wall will at first illustrate, and the other parts of this device of representing in these accompanying drawings also will describe in detail further.From these figure as can be seen: it is diverse the base 3 of elevator 4 being fastened to the conventional apparatus of representing among parts used on the wall of pit 1a of elevator 1 and Fig. 2 and Fig. 3.Just: in the present invention, a kind of tabular secure component, that is: a binding 30 is used to comprise that the fixed parts 34 of nut and lower margin screw rod or analogue is fastened on the wall of pit 1a, is furnished with base fastener hole 31 in the upper end of binding 30.The size in hole 31 and their spacing should be corresponding with two sizes of putting the beams in place and their spacing on the base 3 that is equipped with elevator 3, so that beam 3a can pass hole 31.A metal gusset piece 35 is used to each beam 3a is connected on the binding 30.One end of each gusset piece 35 is soldered to the top of the inside face of corresponding aperture 31.And pass hole on gusset piece 35 and the beam 3a with the fixed parts 37 that comprises nut and screw rod or analogue, the other end of gusset piece 35 firmly is connected on the cooresponding beam 3a.As shown in figure 13, the hole on the gusset piece 35 is that the screw rod by fixed parts 37 passes, and vertically the going up by the generate slotted hole of this Kong Zailiang 3a.Like this, be circle time than this hole, can more easily be connected to gusset piece 35 on the beam 3a with the parts of this generate slotted hole.Obviously is the hole generate slotted hole on the gusset piece 35 rather than on the beam 3a possible, and can obtain identical effect.
As shown in figure 11, since beam 3a be coupled to binding 30 towards one side of machine room 2, rather than towards one side of elevator, then the distance A that is projected in the elevator 1 of the beam 3a of base 3 just can shorten greatly, so, make that elevator is installed becomes easier in narrower elevator.
Figure 14 has represented according to the present invention another embodiment of said elevator hoist apparatus.This embodiment is different from that among Figure 12, single among Figure 12, and wide binding 30 has been divided into two narrow bindings 32 and 33, is furnished with base fastener hole 31 on it.Same method with as shown in Figure 9 binding 30 is fastened to each binding 32 and 33 on the wall of pit 1a with fixed parts 34, is fastened to simultaneously on the base 3a.Figure 15 has represented the diagrammatic sketch that this embodiment among Figure 14 is looked along VII-VII.By shown in Figure 15, binding 30 is divided into two independently narrow bindings 32 and 33, having obtained very important advantage is exactly: each binding can both move along beam 3 independently, like this, even when wall when being very uneven, also can make them each can both be smooth to the wall of the pit 1a of elevator 1.
Because binding 32 and 33 can be supported by the borehole wall, thereby only uses tightening force seldom on the bolt of fixed parts 34, just can firmly be fastened to binding 32 and 33 on the wall of pit 1a so well.In addition, be not bent the binding among Fig. 4 because binding 32 and 33 can not resemble, the power of attempting it is extracted from the pit wall on the holding-down bolt of fixed parts 34 of acting on is than the much less on traditional jacking system.Thereby this embodiment is very superior from the angle of structure.
Although only represented two bindings 32 and 33 among Figure 14, have more than in actual applications and be limited to this number.If base 3 comprises the beam 3a more than three, then can use the binding of corresponding number.
In above each embodiment, the required accuracy requirement of base 3 sizes is that the requirement hole that can make the beam 3a of base 3 pass the binding top gets final product, thereby, the lateral dimension of base 3 and binding does not have exacting requirements, like this, their manufacturing and assembling are easier than the conventional apparatus shown in Fig. 3.
In addition, in above-mentioned each embodiment, all are applied on the end face in hole 31 that the power that makes progress on the base 3 all is passed to binding, like this, load is distributed on the very wide area on the binding, rather than such load as shown in Figure 3 only transmits by gusset piece 10 and fixed parts 9, and at this moment, load only is distributed on seldom the area.Thereby it all is lower being applied to pressure on the binding the same with power on being added to gusset piece 35, like this, size and weight is all reduced.
Figure 16 is mounted in the front elevation according to jacking system of the present invention in the machine room 2 of elevator 1.Elevator 20 is secured to the method on the wall of pit 1a of elevator 1, can use any method in above-mentioned two embodiments.Therefore, much less just connecting between the wall of jacking system and pit 1a understood, in the present invention, split the twice cable ditch 22 that is parallel to each other with the same-handed direction on the drum 21 of elevator 20, rather than the such opposite helical direction of traditional jacking system.Drum 21 is represented very clearly in Figure 17, two the parallel cable ditch 22 of cloth on drum 21, its hand of spiral be near an end of the gear reduction 23 of elevator 20 around the other end to drum 21.Article one, main push-towing rope rope 7a quilt is around in a cable ditch 22, and second main push-towing rope rope 7b quilt is around in another cable ditch 22, so that make two main push- towing rope rope 7a and 7b keeping parallelism always.
Figure 18 has expressed the geometric relationship between the drum 21 of main push- towing rope rope 7a and 7b and elevator 20.Because main push- towing rope rope 7a and 7b always are parallel to each other, then the angle Q between main push- towing rope rope 7a and 7b and the drum 21
1And Q
2All equate, and the length of main push- towing rope rope 7a and 7b also equates.So different with traditional jacking system that Fig. 7 is represented, the load of lift car 5 is equally born by two main push-towing rope ropes, thereby the maximum tension that is applied on each main push-towing rope rope has all reduced.Because the main push-towing rope rope can over burdening, this embodiment has improved safety, make main push-towing rope rope life-saving, prevented that to make that main push-towing rope rope and drum occur dangerous owing to crossing load, and prevented the vibration of the lift car 5 that occurs on the traditional elevator shown in Fig. 5.
Although only express two main push-towing rope ropes among the above-mentioned figure, the bar number of main push-towing rope rope has more than and is limited to two.Article three, or more main push-towing rope rope can be wound in the parallel cable ditch of respective number, its hand of spiral is the end to end from drum 21.
In Figure 18, cable ditch 22 is distributed on the cylinder of drum 21 spirally with the form of right-hand screw thread.Main push- towing rope rope 7a and 7b are coupled to that drum end near gear reduction 23.Thereby because the end of drum 21 and the space size between the gear reduction 23, thereby main push- towing rope rope 7a and 7b are connected to may be difficult on the drum 4a, the length dimension that this depends on the size of drum 21 and the shaft extension of drum 21 is installed.In Figure 19 in represented another embodiment of the invention, two cable ditch have the mode of minus thread in addition, and like this, main push- towing rope rope 7a and 7b are secured on that end face away from gear reduction 23 of drum 21.This just provides bigger working space, so installation main push- towing rope rope 7a and 7b just have been easy to.In the embodiment of stating, the bar number of main push-towing rope rope is not limited to two.If used form with minus thread from drum one end spiral around the parallel cable ditch more than three to the other end, just use the main push-towing rope rope of respective number.
Figure 20 expresses according to the present invention in any embodiment to Figure 22, is used for main push- towing rope rope 7a and 7b are connected to new mode on the drum 21.Though these accompanying drawings have only been represented article one main push-towing rope rope, identical method also can be used for fastening second main push-towing rope rope.Figure 20 is the width of cloth partial plan layout according to an end of the drum 21 of jacking system of the present invention, expresses main push- towing rope rope 7a and 7b are connected to each parts on the drum 21.Figure 21 be Figure 20 cut open along VIII-VIII cutaway view.Figure 22 be cut open along IX-IX among Figure 20 cutaway view, be furnished with a hole 50 on the circle wall of drum 21, the opening in hole 50 is opened on the outer circumference surface of drum 21, and also to a longitudinal terminal surface upper shed of drum 21.The end of main push-towing rope rope 7a fastening a cylindrical git 40, it is passed hole 50 and makes git 40 be fixed on the inside of drum 21, and the fixed parts that fixed charge method end plate 51 is included screw rod and nut or analogue firmly is fastened on the end face of drum 21.And U-shaped screw rod 53 of git 40 usefulness firmly is fastened to plate 51, the U-shaped screw rod is enclosed within tightly in the ditch on the periphery of git.The corresponding hole on plate 51 1 ends is passed in the termination of U-shaped screw rod 53, fixes with nut 54 then, so that git 40 is clipped on the end plate 51 tightly.Hole 50 on drum 21 walls does not also require special shape, as long as even as big as main push-towing rope rope 7a is passed.
With such arrangement as can be seen, the end of main push-towing rope rope 7a is securely fastened on the end of drum 21 by U-shaped screw rod 53 and end plate 51, and no matter whether tension force is applied on the main push-towing rope rope 7a.Thereby, even on lift car 5 touches energy disperser among the pit 7a of passage 7, and when making the main push-towing rope rope become loose, there is no need also to check whether the termination of main push-towing rope rope has come off out from drum 21.In addition, as can be seen: the coupling components of the main push-towing rope rope of representing among Figure 16, need a complex-shaped conductor rope groove 15 and a hole 4g who is suitable for git 14 shapes, and these all will cut on drum 4a.And the hole 50 on the said drum 4a of the present invention does not need the shape of regulation, as long as simple shape is arranged, thereby can be made at an easy rate.And end plate 51 also has same situation.
Although just about bearing two main push-towing rope ropes on the drum, certainly, the main push-towing rope rope number that can install in this way on the drum 21 is not limited to two in the above-mentioned explanation.
