Abstract
The present invention discloses a lift which aims to provide a lift operation speed with a winding method of 1:1. Meanwhile, the force moment of dragging devices is equal to that of dragging devices with a winding method of 2:1 for the lift. The present invention has the design point that the lift comprises the dragging devices, a dragging rope, a counterweight, counterweight ropes and a cage, wherein a left dragging device and a right dragging device are provided; the left dragging device and the right dragging device are synchronously operated; the dragging rope downwards moves to the counterweight from one side of the left dragging device of the dragging rope and is connected with an adjacent counterweight rope; after the other side of the dragging rope is downwards connected to the reverse rope of the cage, the dragging rope upwards passes through the right dragging device. Then, the dragging rope downwards moves to the counterweight and is connected with an adjacent counterweight rope.
Description
Technical field
The present invention relates to a kind of elevator.
Background technology
At present, the elevator of the overwhelming majority by different hoist ropes windings, is realized the vertical displacement movement of elevator by a traction device drives.Wherein the most frequently used hoist ropes winding is 1:1 or 2:1.For the elevator of 1:1 winding, the running velocity of hoist ropes is identical with the running velocity of car, and the running velocity of the elevator rope of 2:1 winding is the twice of cage operation speed.Therefore, to the elevator of same size, the required moment of elevator traction equipment of 1:1 winding is the twice of 2:1 winding, and the required rope speed of elevator traction equipment of 2:1 winding is the twice of 1:1 winding.No matter be the elevator of 1:1 winding or the elevator of 2:1 winding, if when requiring the cage operation speed that reaches same and promoting same weight, all can not satisfy the required moment of elevator of the required moment 2:1 winding of the traction equipment of elevator simultaneously, and the required rope speed of traction equipment is the elevator rope speed of 1:1 winding.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of elevator, and it had both had the elevator speed of 1:1 winding, and the moment of its traction equipment requires the traction equipment with 2:1 winding elevator simultaneously.
For solving the problems of the technologies described above, elevator of the present invention comprises traction equipment, hoist ropes, counterweight and car, and wherein, described traction equipment is two of left traction equipment and right traction equipment, and left and right traction device synchronization operation makes the car lifting; Described hoist ropes from a side of left traction equipment down to counterweight, by equalizer or diversion sheave and to reconnecting, the opposite side of hoist ropes is upwards walked around right traction equipment again down to counterweight after connecting car diversion sheave or equalizer downwards, by equalizer or diversion sheave and to reconnecting.
Compare with prior art, the present invention has following beneficial effect:
The running velocity of elevator is identical with the elevator of same size 1:1 winding.The required moment of the traction equipment of elevator is identical with the elevator of the 2:1 winding of same size.The car diversion sheave does not turn round substantially, so the car diversion sheave can not exert an influence to cage operation, can not bring vibration and noise to cage operation yet.Simultaneously, the car diversion sheave can rotation, thereby regulates the error of two traction device synchronization runnings.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present invention.
The specific embodiment
Elevator of the present invention shown in Figure 1 comprises traction equipment 1,2, hoist ropes 8, counterweight 5, counterweight fag end 3,4, car diversion sheave 7 and car 6, equalizer 9; Right traction equipment 1 and left traction equipment 2 synchronized operations.Described car diversion sheave 7 is arranged on the top of car 6; Described hoist ropes 8 connects counterweight fag end 4 under a side direction of left traction equipment 2, this counterweight fag end 4 joins by equalizer 9 and counterweight 5.The opposite side of hoist ropes 8 is walked around downwards and is upwards walked around right traction equipment 1 behind the car diversion sheave 7 and join with counterweight fag end 3 downwards, and this counterweight fag end 3 joins by equalizer 9 and counterweight 5.
When traction equipment 1,2 rotated, right traction equipment 1 and left traction equipment 2 were born half that elevator moves required moment respectively, and therefore, right traction equipment 1 and 2 of left traction equipment need half of same size 1:1 winding elevator traction equipment moment; Simultaneously, its speed is again half of same size 2:1 winding elevator.Wherein, car diversion sheave 7 does not change substantially, can not bring vibration and noise to cage operation; Simultaneously, car diversion sheave 7 can rotation, thereby regulates two traction equipment, 1,2 synchronous operated errors.Equalizer 9, the operation deviation that plays two traction equipment 1 of automatically regulating and 2 (for example, because the running velocity of the manufacturing errors of traction sheave, traction equipment 1 and 2 is inconsistent, the deviation that the not equal factor of the elongation of hoist ropes 8 produces), thereby can guarantee that counterweight 5 deflection can not occur, can not influence the operation of elevator.
In the embodiment as Fig. 1, equalizer 9 also can be a diversion sheave, and cancellation counterweight fag end 3 and 4, thereby reaches the same effect of embodiment shown in Figure 1.
Described car diversion sheave or equalizer can be arranged on the top or the bottom of car.
Described traction equipment is arranged in the hoistway of elevator(lift) machine room or elevator.
Claims (3)
1, a kind of elevator comprises traction equipment, hoist ropes, counterweight and car, it is characterized in that: described traction equipment is two of left traction equipment and right traction equipment, and left and right traction device synchronization operation makes the car lifting; Described hoist ropes from a side of left traction equipment down to counterweight, by equalizer or diversion sheave and to reconnecting, the opposite side of hoist ropes is upwards walked around right traction equipment again down to counterweight after connecting car diversion sheave or equalizer downwards, by equalizer or diversion sheave and to reconnecting.
2, elevator as claimed in claim 1 is characterized in that: described car diversion sheave or equalizer can be arranged on the top or the bottom of car.
