Description
Technical field
The present invention relates to be applied to lift type parking apparatus, lifting cross-sliding type (elevator slide) parking apparatus and passenger elevators etc. lifting drive and possess the mechanical parking equipment of this lifting drive.
Background technology
In the past, lift type parking apparatus, lifting cross sliding type parking equipment and passenger elevators etc. has lifting drive lifting body (elevator carrier, gondola etc.) being elevated with hawser.In this lifting drive, be at one end provided with the other end of the hawser of lifting body, the elevator equilibrium of forces hammer reducing lifting body is set, to carry out lift-on/lift-off type action on the traction sheave that the centre portion of this hawser is suspended on drive source.In this lifting drive, by the friction drive hanging hawser on the traction sheave, lifting body is elevated.
As the example of equipment possessing the lifting drive that this type of utilizes the friction drive of hawser to make lifting body be elevated, below, will be described for above-mentioned lift type parking apparatus (mechanical parking equipment).
Lift type parking apparatus is generally provided with lifting drive in the Machine Room being arranged at top, be suspended on as the hawser on the elevator carrier of lifting body bending to the direction of lifting drive by the slewing rollers being arranged at above-mentioned Machine Room, drive this hawser with lifting drive.As shown in Figure 6, after hanging on the traction sheave 101 of drive source with the hawser 100 that lifting drive drives, bent downwards by slewing rollers 102, and the lower end of this hawser 100 is provided with bob-weight.Such lifting drive is with drive source rotary actuation traction sheave 101, utilizes the friction drive of the hawser 100 be suspended on this traction sheave 101 to make elevator carrier be elevated (for example, referring to patent documentation 1).
Utilize in the lifting drive of such friction drive, propulsive effort as described below acts on the hawser 100 that is wound on traction sheave 101.Further, although in fact various to acceleration/accel, loss due to friction etc. parameter is relevant, the correlation parameter that only simple declaration is main.
At the cable tension that the weight of the elevator carrier being mounted with the vehicle that need promote with lifting drive is produced as " T1 ", when the cable tension weight of bob-weight produced is as " T2 ", need be △ T=T1-T2 with the propulsive effort " △ T " that traction sheave 101 transmits.
Weight as the elevator carrier in lift type parking apparatus has " real vehicle " of equipped vehicle and does not have the state of " empty wagons " of equipped vehicle, in order to play propulsive effort to greatest extent in two states, the weight set of bob-weight is by these weight changed on a rough average.Further, the engagement groove shape of above-mentioned traction sheave 101 and the specification etc. of hawser 100 are set as the maximum driving force transmitted with this form is reached " △ T ".
On the other hand, when the reason such as weight increase due to elevator carrier needs to guarantee larger friction drive, usually along with the increase of the weight ratio of elevator carrier and bob-weight, strengthen the cornerite of the hawser on traction sheave, but this weight ratio had cannot transmit sufficient friction drive by the wrap angle sigma of the such as structure of above-mentioned patent documentation 1.
So, such as, in passenger elevators, the cornerite of hawser is increased to more than 180 °, for this reason, repeatedly spooled cable (for example, referring to patent documentation 2,3) on the traction sheave and diverting pulley of winch.
Prior art document:
Patent documentation 1: Japanese Unexamined Patent Publication 2005-201010 publication;
Patent documentation 2: Japanese Unexamined Patent Publication 2004-106984 publication;
Patent documentation 3: Japan is public table patent No. 2004/041703 publication again.
But, as as described in above-mentioned patent documentation 2,3, when hawser is repeatedly reeled on the traction sheave, the bearing reaction putting on the output shaft bearing of traction sheave and the moment of deflection putting on output shaft due to winding times increase caused by the increase of cable tension and twice, trebly significantly become large.
On the other hand, as shown in Figure 7, in lifting drive 110, the output of usual CD-ROM drive motor 111 omits inner structure at reductor 112() in deceleration, and be passed to traction sheave 101 from output shaft 113.Thus, when being applied with because of the cable tension of above-mentioned increase the tension force Ta represented with arrow on traction sheave 101, rotating the bearing 114 supporting to be assembled in the output shaft 113 of reductor 112, be applied with the power parallel with tension force Ta and the moment proportional with the overhang S of the point of action of tension force Ta on 115, and antagonistic force Ra and antagonistic force Rb relative to these sum effects.The power and the moment sum proportional with overhang that are equivalent to this tension force are called overhang load (OHL).
Therefore, in order to increase the friction drive of lifting drive 110 and the winding times increasing hawser makes tension force increase time, above-mentioned overhang load becomes large along with the increase of this tension force, even if winding times meets required transmission torque peak, the situation of the benchmark that cannot meet overhang load also can be there is.Now, should manage to improve output shaft 113, output shaft bearing 114, the intensity of 115 grades, but when managing to improve intensity, lifting drive 110 can become complicated and weight increases, and the special product of intensified bearing should be used as required, cause lifting drive 110 complicated, maximize and high cost, become the lifting drive not having practicality.
Summary of the invention
Therefore, even if the object of the present invention is to provide the winding times of the hawser increased on traction sheave, the lifting drive that the antagonistic force putting on bearing increases and the mechanical parking equipment possessing this lifting drive also can not be made.
In order to achieve the above object, lifting drive of the present invention has output shaft by bearing support on drive source, by the lifting drive that the friction drive being wound on the hawser be installed on the traction sheave of this output shaft makes lifting body be elevated, possess: the diverting pulley configured with described traction sheave subtend; The support member that base portion is rotatably supported on described output shaft, leading section rotatably supports described diverting pulley; Keep the position retaining member of the relative position relation between described support member and described drive source; After described hawser is wound in described traction sheave, is wound in described diverting pulley, and then is wound in traction sheave, thus be repeatedly wound in this traction sheave.By this structure, even if hawser winding times is on the traction sheave increased to repeatedly, owing to supporting diverting pulley with being supported in the support member be provided with on the output shaft of traction sheave, therefore the increase part acting on the cable tension of traction sheave and diverting pulley for and act on support member, this increase part is absorbed by support member, thus can inhibit function in the increase of the bearing reaction of output shaft.So, hawser can be repeatedly wound in the large lifting drive of the friction drive of traction sheave with simple Structure composing.And, the lightweight of the lifting drive with large propulsive effort can be realized.
Again, also can be that the described base portion of described support member is supported on output shaft by bearing; Described diverting pulley is supported on the leading section of described support member by bearing.Such formation, the output shaft rotated owing to making traction sheave rotatably supports the base portion of support member by bearing, on the leading section of support member, rotatably support diverting pulley by bearing simultaneously, therefore can keep long-time stable and rotate swimmingly supporting diverting pulley and support member.
Again, also can be that described output shaft has the extending shaft extended from the mounting portion of described traction sheave, the extending shaft of this output shaft is rotatably supported by bearing the base portion of described support member.Such formation, easily can support support member by the output shaft changing drive source, diverting pulley easily can be configured and go up in place.
Again, also can be the supporting axis at the leading section of described support member with described diverting pulley, described diverting pulley be rotatably supported on this supporting axis by bearing.Such formation, can keep the leading section of the support member of relative position relation stably to support diverting pulley with fixed position with drive source.
Again, also can be pivot center from angle of inclination (from traction sheave be wound to the hawser of diverting pulley, and the angle hawser that from diverting pulley be wound to traction sheave between) that traction sheave be wound to the engagement groove of diverting pulley the tilting with described hawser of pivot center relative to described traction sheave of described diverting pulley.Such formation, owing to being suspended from diverting pulley from traction sheave, reverse hawser successfully hangs in the adjacent engagement groove of traction sheave, and the transition that therefore more successfully can realize the hawser hanging on traction sheave and diverting pulley is hung.
Again, also can be that described diverting pulley is configured on the cable tension action direction of described traction sheave, the diameter of this diverting pulley be less than the diameter of described traction sheave." tension force action direction " in this specification sheets and claim refers to the weight trailed direction of hawser because of lifting body.Such formation, is configured between hawser by the diverting pulley be configured on the tension force action direction of hawser, therefore can form lifting drive compactly.
On the other hand, mechanical car stopping device of the present invention possesses above-mentioned arbitrary lifting drive.By this structure, in order to increase the friction drive making lifting body be elevated, even if the winding times increasing the hawser of lifting drive increases cable tension, also can inhibit function in the increase of the antagonistic force of output shaft bearing, form the lifting drive of simple structure, therefore can form the mechanical parking equipment that the configuration degree of freedom of lifting drive is high.
According to the present invention, even if increase the winding times of hawser on the traction sheave, the increase of bearing reaction also can not be caused because of the increase of cable tension, therefore can with the large lifting drive of simple Structure composing friction drive.

As shown in Fig. 5 (a), Fig. 5 (b), according to above lifting drive 20, even if the winding times of the hawser 21 on traction sheave 30 increases, the antagonistic force of the bearing putting on drive source 25 also can not be made to increase.Further, in the following description, although in fact also parameter various to acceleration/accel, loss due to friction etc. is relevant, main correlation parameter simple declaration is only used.Further, said structure is described in conjunction with its symbol.
[relation of 1. propulsive effort and loading]
As mentioned above, the pass between the cable tension " T2 " that the cable tension " T1 " that the weight being mounted with the elevator carrier 16 of the vehicle V promoted with lifting drive 20 produces, the weight of bob-weight 22 produce and the propulsive effort " △ T " that need transmit with traction sheave 30 is:
△T=T1-T2。
Further, suppose that the weight of bob-weight 22 sets according to loaded weight (=" real vehicle "-" empty wagons ")=2* △ T.Further, for the angle of contact α of the hawser 21 in above-mentioned traction sheave 30, hawser 21 is being passed through the reverse front and back of diverting pulley 40, and any angle of contact be wound on traction sheave 30 is assumed to be " angle of contact α ".
Under such imposing a condition during supposition perfect condition, because the hawser 21 of tension force " T1 " side is wound in traction sheave 30 with angle of contact α, can bear the considerable part of above-mentioned propulsive effort " △ T " with this, therefore the hawser minimum tension " T3 " of diverting pulley 40 side is:
T3=T1-△T。
On the other hand, because the supporting axis 55 of diverting pulley 40 can rotate freely, therefore the tension force " T4 " of the 2nd winding side is:
T4=T3。
In addition, make hawser 21 in diverting pulley 40 oppositely and be wound in traction sheave 30, can bear the considerable part of above-mentioned propulsive effort " △ T " with this, therefore the cable tension " T2 " of bob-weight 22 side be as following:
T2=T4-△T
=T1-△T-△T
=T1-2*△T；
Like this, by connecting by support member 50 on the output shaft 26 of traction sheave 30 and supporting diverting pulley 40, the increase part of the cable tension produced can be increased with support member 50 winding times absorbed because of hawser 21, the lifting drive 20 of the simple structure of the phenomenon that drive source 25 there will not be bearing reaction to increase can be formed in.
Namely, as shown in Figure 6 above, when independent earth's axis support slewing rollers 102, the tension force Ta acting on traction sheave 101 acts on drive source as overhang load under immovable state, but as above-mentioned lifting drive 20, diverting pulley 40 and traction sheave 30 is rotatably connected by the support member 50 supported with output shaft 26, the tonicity component produced by the tension force " T4 " of the minimum tension of hawser " T3 " and winding side can be born by support member 50, and the power acting on drive source 25 as overhang load can be made to be only by cable tension " T1, T2 " tension force that produces.
Conclusions also can be learnt by following, and the tension force Ta namely acting on above-mentioned traction sheave 30 is: Ta=T1+T2+T3 '+T4 ',
(" T3 ' " is the tension force action direction component of " T3 ", and " T4 ' " is the tension force action direction component of " T4 "), and the antagonistic force Tb acting on diverting pulley 40 is:
Tb=T3’+T4’。
Like this, according to above-mentioned lifting drive 20, even if hawser is wound in traction sheave 30 more than 21 time, overhang load overhang load is also about " half hang " of 180 ° during with the angle of contact α of the hawser 100 being wound in traction sheave 101 is as shown in Figure 6 equal.And, according to above-mentioned lifting drive 20, by reducing cable tension, can overhang load be reduced, form more small-sized lifting drive 20.
[application 2. in mechanical parking equipment]
In above-mentioned [relation of 1. propulsive effort and loading], describe the situation that the absolute value of " T1 " is equal.Although detailed, the absolute value of propulsive effort when lifting body loading is different and minimax tension force is proportional.That is, when minimum tension (weight of the elevator carrier 16 of " empty wagons ") diminishes, transferable propulsive effort diminishes therewith pro rata.
So, when above-mentioned lifting drive 20 being applied to the mechanical parking equipment of lift type parking apparatus 1 grade, following effect can be expected:
Even if a the absolute value of () minimax tension force diminishes, also can guarantee large propulsive effort, therefore can expand Tension Difference, realize the lightweight of elevator carrier 16;
If b the absolute value of () minimax tension force is identical, then can transmit larger propulsive effort, acceleration/accel therefore can be made to become large, the high speed of the elevator carrier 16 be elevated can be realized;
C () becomes large to make propulsive effort, usually reduce the holding angle of the engagement groove of hawser 21, improve the pressure to hawser 21 with wedge effect, but the essentiality done like this in above-mentioned lifting drive reduces, and therefore can expect the life-time dilatation of hawser 21.
Like this, if above-mentioned lifting drive 20 is applied to lift type parking apparatus 1(mechanical parking equipment), then can play various effect.
And, in above-mentioned example, an example as mechanical parking equipment describes lift type parking apparatus 1, but lifting drive 20 of the present invention can be applied to the passenger elevators of the jacking system that tool back up cable 21 winding promotes or winding declines and whole mechanical parking equipments, is not limited to above-mentioned example.
Further, because above-mentioned lifting drive 20 is the top-driven example in mechanical parking equipment, therefore landscape configuration CD-ROM drive motor 23, but also can in mechanical parking equipment, bottom be adopted to drive.Under these circumstances, longitudinal configuration driven motor 23, hawser 21 is configured to upwards extend.As long as the configuration direction of such lifting drive 20 is configured to the direction being applicable to the equipment possessing lifting drive 20, be not limited to above-mentioned example.
In addition, above-mentioned example just illustrates an example, and can carry out various change in the scope not changing present inventive concept, the present invention is not limited to above-mentioned example.
Industrial application:
The mechanical parking equipment and passenger elevators etc. of lift type parking apparatus, lifting cross sliding type parking equipment etc. can be used according to lifting drive of the present invention.
