Wherein：II transmission gear 11 of main shaft is engaged with clutch gear 13, and intermediate shaft transmission gear 15 is engaged with I transmission gear 17 of main shaft.
Principle and the course of work：
When elevator works, power is transmitted to main shaft I and main shaft II respectively through transmission system (being not drawn into figure), at this point, from
It closes gear 13 and is in bonding state with jackshaft 14, to can guarantee that main shaft I and main shaft II rotate synchronously.Main shaft I is with moving gear
It is driven the supporting rack rotation of tension balance device 19, and left by balancing bevel gear, output bevel gear wheel drive No.1 main shaft device
The right roller 18 of roller 20, No.1 main shaft device rotates, to drive No.1 hoisting container 24 to be promoted (or decentralization)；II 12 band of main shaft
The supporting rack of moving gear transmission tension balance device 21 drives No. two main shaft devices to roll left by balance bevel gear, output bevel gear wheel
The right roller 10 of 22, No. two main shaft devices of cylinder rotates, to drive No. two decentralizations of hoisting container 23 (or promotion).
By taking No.1 main shaft device as an example, since the two output bevel gear wheel of left and right being meshed with balance bevel gear can only transmit phase
With torque, it is therefore, equal or two when being connected to winding radius of two boom hoist cables of same hoisting container on roller
When the coefficient of elasticity of steel wire rope is equal or the equal length of two steel wire ropes, the torque balanced suffered by bevel gear both sides is equal, No.1
The balance bevel gear of main shaft device gear drive tension balance device 19 is in revolves round the sun but not autorotation around main shaft I, such
Two boom hoist cables have equal tension under state, i.e. two steel wire rope tensions balance and two rollers and main shaft I are with identical turn
Speed rotates and is in relative static conditions.
When keeping the length of two steel wire ropes of the same container of connection unequal due to the error in being installed in steel wire rope, such as connect
The wherein steel cable (such as No.1 main shaft device right steel wire rope 7) of No.1 hoisting container 24 is connect than another steel cable (No.1
The left steel wire rope of main shaft device 5) it is longer when so that the right steel wire rope 7 of No.1 main shaft device is in slack rope state, and No.1 main shaft device
Left steel wire rope 5 is in tight rope state.When elevator starts to be promoted work (main shaft I is to rotate clockwise at this time), make No.1 master
The tension of the left steel wire rope of shaft device 5 is more than the tension of the right steel wire rope of No.1 main shaft device 7, to make the power of balance bevel gear both sides
Square is no longer on equivalent state, makes to balance the generation counter clockwise direction rotation of bevel gear 26, lower balance bevel gear 31 generates up time
Needle direction rotation, to make left output bevel gear wheel 32 and the No.1 main shaft device connected with it cylinder 20 that rolls left be slower than I turn of main shaft
It is dynamic；On the contrary, the right roller 18 of the right output bevel gear wheel 28 and the No.1 main shaft device connected with it that are engaged with balance bevel gear is fast
It is rotated in main shaft I, the left steel wire rope of No.1 main shaft device 5 to keep the right steel wire rope 7 of No.1 main shaft device of pine tighter is with very fast
Speed be wound on the right roller of No.1 main shaft device 18, after eliminating two rope capacity differences, two steel wire rope tensions reach flat
Weighing apparatus state, balance bevel gear stop rotation, and main shaft I drives No.1 main shaft device gear drive tension balance device 19 to pass through balance
Bevel gear, output bevel gear wheel drive the No.1 main shaft device right roller 18 of cylinder 20, No.1 main shaft device that rolls left to rotate synchronously, to make
Two steel wire ropes drive No.1 hoisting container 24 to promote cargo under equalization of strain state.It is decentralization No.1 hoisting container 24 when at this time
When, the rotation direction of main shaft I is with rotation direction when promoting No.1 hoisting container 24 on the contrary, main shaft I is counterclockwise to turn
It is dynamic.In the case, right output bevel gear wheel 28 and the right roller of the No.1 main shaft device connected with it 18 is made to be slower than I turn of main shaft
It is dynamic；On the contrary, the left output bevel gear wheel 32 and the roller 20 connected with it that are engaged with balance bevel gear are faster than main shaft I and rotate, i.e.,
The roller 18 connected with loose steel wire rope 7 is set relatively to be slower than the rotation of main shaft I, the No.1 main shaft device being connected with tight steel wire rope 5 rolls left cylinder
20 are relatively faster than the rotation of main shaft I, and after eliminating two rope capacity differences, two steel wire rope tensions reach equilibrium state, balance bevel gear
Stop rotation, main shaft I drives No.1 main shaft device gear drive tension balance device 19 by balancing bevel gear, output bevel gear wheel
The No.1 main shaft device right roller of cylinder 20, No.1 main shaft device 18 that rolls left is driven to be rotated synchronously with main shaft I, to make two steel wire ropes exist
No.1 hoisting container 24 is transferred under equalization of strain state.
When connect the elastic stiffness of two steel wire ropes of same container it is unequal when, such as the left steel wire rope of No.1 main shaft device 5
Elastic stiffness when being more than the elastic stiffness of the right steel wire rope of No.1 main shaft device 7 so that two steel wire ropes under the same load, No.1
The deformation for deforming less than the right steel wire rope of No.1 main shaft device 7 of the left steel wire rope of main shaft device 5, to make the left steel of No.1 main shaft device
Cord 5 is in tight rope state, and the right steel wire rope 7 of No.1 main shaft device is in slack rope state.At this point, the left steel wire rope of No.1 main shaft device
The roll left torque of cylinder 20 of 5 pairs of No.1 main shaft devices is more than the right steel wire rope of No.1 main shaft device 7 to the right roller of No.1 main shaft device 18
Torque, since left output bevel gear wheel 32 and right output bevel gear wheel 28 roll left with No.1 main shaft device cylinder 20 and No.1 main shaft respectively
The right roller of device 18 is fixedly connected with, and therefore, the torque that left output bevel gear wheel 32 acts on balance gear is made more than right output gear 28
For the torque of balance gear, to make upper 26 clockwise direction rotation of balance bevel gear, keep lower balance bevel gear 31 clockwise
Direction rotation, as a result make No.1 hoisting container 24 when promoting cargo (main shaft I rotates clockwise at this time) left output gear 32 and
The connected No.1 main shaft device cylinder 20 that rolls left lags behind the rotation of main shaft I therewith, and right output bevel gear wheel 28 and therewith connected one
The right roller of number main shaft device 18 is ahead of the rotation of main shaft I, until eliminating due to the change that two steel wire rope elastic stiffness are different and generate
After the difference of shape, the tension of two steel wire ropes is finally made to reach balance.Since the elastic stiffness of steel wire rope and the length of steel wire rope are related,
Therefore, the modified difference of elevator two steel wire ropes in lifting process is generating at any time, and being balanced mechanism again at any time will be generated
Modified difference is eliminated, to ensure that the tension of two steel wire ropes is in equilibrium state always in entire lifting process.Under being at this time
When putting No.1 hoisting container 24, the rotation direction of main shaft I is with rotation direction when promoting No.1 hoisting container 24 on the contrary, main shaft
I is to rotate in an anti-clockwise direction.In the case, left output gear 32 and the No.1 main shaft device connected with it is made to roll left cylinder 20
It is faster than the rotation of main shaft I；On the contrary, the right output gear 28 and the No.1 main shaft device connected with it that are engaged with balance bevel gear are right
Roller 18 is slower than the rotation of main shaft I, to make the No.1 main shaft device being connected with the left steel wire rope 5 of tight No.1 main shaft device roll left cylinder
20 are relatively faster than the rotation of main shaft I, and the right roller of connected No.1 main shaft device 18 is relatively slower than with the right steel wire rope 7 of No.1 main shaft device of pine
Main shaft I rotates, until after eliminating the difference due to the deformation that two steel wire rope elastic stiffness are different and generate, finally makes two steel wire ropes
Tension reaches balance.As promoting No.1 hoisting container 24 with elevator, elevator during transferring No.1 hoisting container 24,
The tension of equally certifiable two steel wire ropes of balance mechanism is in equilibrium state always during entirely decentralization cargo.Elevator exists
When being operated in the case of the elastic stiffness of two steel wire ropes is unequal, since tension balance device will pass through statocone all the time
Gear transfers the modified difference for eliminating two steel wire ropes because caused by the elastic stiffness of two steel wire ropes is unequal certainly, to reach two
The equalization of strain of steel wire rope.So in this case, elevator it is entire promoted or decentralization process in, left and right two roller with
Exist between main shaft I and always between two rollers and relatively rotates.
When the diameter of two steel wire ropes due to connecting same container is unequal, or loaded on same axis (such as main shaft I)
The diameter of two rollers is unequal, or due to first two and steel wire rope various other reasons in multi-lay winding cause two rollings
When the coiling diameter of cylinder is unequal, such as No.1 main shaft device rolls left the coiling diameter D of cylinder 2020More than the right rolling of No.1 main shaft device
The coiling diameter D of cylinder 1818, i.e. the coiling diameter difference of two rollers is △ D=D20-D18When, due to the left output bevel gear of two output gears
Wheel 32 and right output bevel gear wheel 28 transmit equal torque, so, there is following relationship in elevator, i.e., always during the work time
T7D18=T5D20
Or T7D18=T5(D18+ΔD) (1)
It is obtained by formula (1), the tension difference of two steel wire ropes is
T in formula5、T7--- it is respectively the tension of the left steel wire rope 5 of No.1 main shaft device and the right steel wire rope of No.1 main shaft device 7；
D20--- No.1 main shaft device rolls left the coiling diameter of cylinder 20；
D18--- the coiling diameter of the right roller of No.1 main shaft device 18；
Δ D --- No.1 main shaft device roll left cylinder 20 and the right roller of No.1 main shaft device 18 coiling diameter it is poor.
Formula (2) shows that this gear drive tension balance device cannot be true when the coiling diameter of two rollers is unequal
Protect the equalization of strain of two steel wire ropes.But since the coiling diameter difference of two rollers is generally much smaller than the right roller of No.1 main shaft device 18
Coiling diameter.Therefore, because two steel wire rope tension imbalances will not be right caused by the coiling diameter of two rollers is unequal
The normal work of elevator causes substantive influence.In this case, since the tension of two steel wire ropes is by the pact of formula (2)
Beam, therefore, no matter No.1 hoisting container 24 is to promote cargo or decentralization cargo, and No.1 main shaft device rolls left cylinder 20 will be slow always
It is rotated in main shaft I, and the right roller of No.1 main shaft device 18 will be consistently faster than main shaft I and rotate.
When elevator needs to adjust rope, two rollers on a certain main shaft can be braked as needed, such as by main shaft I
On two rollers braked, so that two rollers on main shaft II is in the state that declutches, opening the clutch of clutch gear 13 makes it
It is disconnected with jackshaft 14, while starting the power of main shaft II to drive its rotation, to complete the tune rope work of elevator.By
This is as it can be seen that the utility model gear drive equalization of strain multi-rope winding type mine hoist is not necessarily to that special rope-adjusting clutch is arranged
Realize the tune rope work of elevator.
When No. two main shaft devices generate various influences above-mentioned two steel wire ropes (the left steel wire rope 6 of No. two main shaft devices and No. two
The right steel wire rope of main shaft device 8) equalization of strain factor when, operational situation is identical with No.1 main shaft device, here no longer
It repeats.
