Detailed description of preferred embodiment
Fig. 1 has schematically shown elevator device 20, and it can be convenient to car 22 and move to selected position between first end (being the top), 24 and second end (i.e. bottom) 26 of hoist-hole.System 20 comprises load member 30, and it has supported the weight of car and has been convenient to the required motion of car 22.Those of skill in the art recognize that and in system designed according to this invention, can use multiple load member 30.In a specific example system, adopted coated steel strips.Another example system comprises at least one cable wire.For purposes of discussion, following description uses term " band " conduct to exchange with the load member of any kind of, and term " band " should not be construed as the meaning of its narrow sense.
Load member 30 has near the end 32 first end 24 that is fixed on hoist-hole.Accompanying drawing has schematically shown conventional terminal member 34.Be with 30 to extend towards car 22, be wrapped at least one at the car place with should bringing to small part and be supported on the pulley 36 that can move with car 22 from this end.Back extend towards first end 24 of hoist-hole then with 30, this is wrapped on another pulley 38 with bringing to small part there.
Extend with 30 second ends 26 towards hoist-hole subsequently, this is wrapped at least one pulley 40 with bringing to small part there.Be with 30 to stretch to car 22 therefrom, be wrapped at the car place with should bringing to small part and be supported on another pulley 42 that can in hoist-hole, move with car.With 30 and then extend towards second end 26 of hoist-hole.
Tensioner 44 is fixed the other end 45 with 30, guarantees to have an amount of tension force to be applied on the load member, so that support car fully and necessary haulage is provided, thereby obtains desirable car movement.Make band around the drive pulley motion by controlling the machine 46 that comprises electrical motor in known manner, just can obtain the motion of car.In example shown in Figure 1, machine 46 is associated with near the pulley 40 that is positioned at hoist-hole second end 26, makes that pulley 40 is traction wheel or drive wheel.When electrical motor make be with 30 when the pulley motion car will rise or descend, this depends on the sense of motion of electrical motor and drive wheel.
Because tensioner 44 has been kept the tension force of aequum on 30, so traction wheel can make band and car movement.Tensioner is supported for and can keeps static basically near hoist-hole one end.In example shown in Figure 1, tensioner be supported on hoist-hole second end 26 near.In another example, tensioner 44 be supported on first end 24 near.Adopt the tensioner (as conventional counterweight) that does not move in hoist-hole can improve the efficient of hoist-hole, this is because it has greatly reduced the required space of parts that holds elevator device.Removing the cost savings that moving counterweight brings is remarkable advantages of the present invention.
Fig. 1 has just schematically shown one example system arranged according to this invention.In this example, the wiring ratio has reached 2: 1, is twices of car 22 mobile vertical distance in response to this motion of band with 30 distances that move around drive wheel wherein.For example in Fig. 5, other settings of 2: 1 have been shown at Fig. 2.For example other wirings of 3: 1 and 4: 1 also are feasible than in the present invention.
Exemplary setting shown in Figure 2 and the difference among Fig. 1 mainly are the layout of machine 46.In this example, machine 46 be supported on hoist-hole first end 24 near.In this example, pulley 38 is traction wheels.
Fig. 3 has shown another example system designed according to this invention.In this example, the pulley that is associated with car 22 is so-called underslung setting.Although the part with 30 of extending towards hoist-hole first end 24 is wrapped on the pulley 38, yet pulley 36 is supported on the below of car 22.Rely on this specific car supporting construction, this set can make system more economical.
Fig. 4 has shown another kind of so-called top suspension setting.In this example, pulley 42 and pulley 36 are supported on the top of car 22.
Fig. 5 has schematically shown another kind of exemplary system construction.Here, machine 46 and in previous examples with pulley in one directly related.This example comprises the dedicated drive sheave 50 that is associated with machine 46.Wheel flutter 52 can promote to be with 30 to guide machine location into, get back to then its be about in the track of advancing with hoist-hole in the pulley compounding practice.In according to example of present embodiment design-calculated, machine 46 is positioned at outside the hoistway envelope.This structure allows intention ground machine is arranged in any desired position.
Tensioner 44 can adopt various forms.In an example, tensioner comprises the mass that maintenance is static relatively.In example shown in Figure 6, mass 54 be arranged on hoist-hole second end 26 near.This exemplary mass 54 has the part 56a and the 56b of interlocking, and making can be at erecting stage assembly quality piece.By mass 54 being divided into a plurality of parts that can be fixed together at work-site, just can simplify the work that mass 54 is transported to work-site and elevator device is installed.Can use multiple interlocking or connecting arrangements to come as required part 56a and 56b to be fixed together.
In another example, mass 54 comprises can locate ghost or the template that selectivity is filled in the place of erection.The selected material such as the cement concrete of aequum can be filled in this ghost or the template, to obtain required weight.
The total weight of mass 54 preferably is arranged to keep the tension force of aequum on load member 30, to obtain required elevator device operation.In an example, mass 54 is preferably greater than or equals the quality of car 22 and half of the cargo-carring rated load, nominal load quality of its expection sum.This relation can be used formula: M CWT=(M CAR+ M DLExpress)/2.The acceleration/accel of this relational assumption car can be left in the basket, and supposition draw ratio (being the warp tension ratio on drive wheel 34 both sides) in this example system approximately is 2.
In another example, the size of mass 54 is preferably determined according to following formula:
M CWT = 0.5 ( M CAR + M DL ) ( g + a ) + 3 Hρa + 0.25 H ρ PC ( g + a ) g ( TR - 1 )
Wherein:
ρ is tightwire wire density (kg/m),
H is the height (m) of building,
A is car acceleration/accel (m/s 2),
G is acceleration due to gravity (m/s 2),
M CARBe car quality (kg),
M DLBe rated load, nominal load quality (kg),
M CWTBe weight mass (kg),
ρ TCBe line motion cable wire density (kg/m) and
TR is a draw ratio.
Just as known, haulage is band or the winding angle of cable wire and the function of friction coefficient.Selection can provide the parts (for example flat band but not round steel rope) of bigger friction to allow to use less mass 54.Preferably, mass 54 is littler than conventional counterweight, so that can promote the saving that method of the present invention is brought.
Example shown in Figure 6 comprises the lever assembly 58 that supports mass 54 round pivot 60, and pivot is fixed on the wall of hoist-hole for example rightly.Lever assembly 58 makes can be fixed on to sentence with respect to the certain position of suspended mass 54 with 30 just realizes mechanical advantage.This set has further increased and uses less mass 54 but still can obtain ability by the much bigger equal tension that counterweight provided.
During the elevator device operation, need mass 54 to do some motions in some cases.For example, state or the load that changes on the load member 30 may need mass 54 to make small movements to adapt to this situation.The elasticity of load member 30 changes relatively typical case, and some finite motions of mass can be held this variation.Yet, to compare with the motion of car 22 in hoist-hole, any this motion of mass 54 all is very limited.Therefore, mass 54 is actually static, the amount of exercise that conventional counterweight experienced of its any motion in the conventional elevator device.
Schematically shown guiding device 62 in Fig. 6, it is used to hold any required motion of mass 54 with respect to hoist-hole bottom 26.In this example, guiding device 62 comprises the structure that is fixed on a pair of similar guide rail in the hoist-hole.Slide rail 62 has the bottom on the floor that is fixed on 26 places, hoist-hole bottom.Another slide rail 62 is fixed on the hoistway wall in the mode of routine.
In Fig. 7, schematically shown another example tension device 44.But this example comprises the spring members 64 of at least one fastening belt 30.Adaptor union 66 is convenient to the terminal member with 30 a end 45 places is fixed on being provided with of spring members 64.
In Fig. 8, schematically shown another example tension device 44.In this example, at least one pressurized actuator 68 provides and has kept the required tension force of desired system operation.In an example, actuator 68 is fluid pressure types.In another example, actuator 68 is pneumatic types.Conventional tension adjustment techniques can promote the amount of tension that provides required.Adaptor union 66 can promote to allow a plurality of actuators 68 that the mode of required tension force is provided and to fix and be with 30.
The those skilled in the art who benefits from this specification sheets can determine how to select for example suitable mass, spring assembly or pressurized actuator device, so that satisfy the requirement of their extraordinary circumstances.
Elevator system designed according to this invention can be brought a series of advantage.A remarkable advantage is to have improved the hoist-hole utilization of space by the mode of saving the space, has therefore improved the economy of elevator device.Owing to keep static basically in the select location of tensioner 44 in hoist-hole, therefore just do not need independent weight guide, can reduce the quantity of miscellaneous part, also can reduce the overall dimensions of hoist-hole if necessary.
Another advantage is to have simplified driving and brake component.For example, owing to there is not moving counterweight, therefore only need brake in one direction.
Another advantage of system designed according to this invention is that its feasible mounting means that jumps is realized easily.Fig. 9 has schematically shown the example system that another designs according to the present invention and install temporarily under first state in hoist-hole.In this example, ground floor or height 72 places of top braces 70 in building are fixed with respect to hoist-hole.This for example can accomplish in building is still being built.Can realize the suitable parts in the elevator device are fixed on the top braces 70 by conventional approach.Top braces 70 can be fixed on desired locations in the hoist-hole by conventional approach.
In this state, car 22 can be used to convey goods between the different layers of height below 72 in building.Under this interim state of installing, the part 74 of load member 30 remain on the separated bobbin 75 of the operate portions of elevator device on.Can utilize conventional grip device 73 that the select location on the load member 30 is fixed on the tensioner 44.By the lax or redundance with 74 is remained on outside the system effectively, under this interim installing condition, load member 30 has and is in intrasystem first length.
In Fig. 9, shown second installation site with dotted line.Under this state, top braces 70 is supported on the second layer or height 76 places in the building.By car is fully fixed at the perch place, unclamp load member from the junction of tensioner 44, top braces 70 is moved on to second height and position, then load member 30 is retightened on tensioner 44, this innovation setting just allows to carry out the transition to second height 76 from first height 72.In the second place, previous redundance 74 is in the work system at least in part, and load member 30 has second length that is in the elevator device, and wherein this second length is greater than first length.In this position, lift car 22 can arrive the multilayer place in the building.
According to the height of the demand and the specific buildings of particular case, this process can repeat repeatedly as required.This innovation is arranged so that and can by jump lift sequence elevator device be installed in more effective mode.In addition, for system designed according to this invention, the ability of handling the long load member between the installation site also obtains simplifying.
Foregoing description is exemplary and nonrestrictive in itself.Those skilled in the art can know the changes and improvements to disclosed example that do not break away from essence of the present invention.Legal protection scope of the present invention has only by studying following claim and could determine.
