Description
Technical field
The present invention relates to a kind of lift appliance.More specifically, it is related to a kind of elevator rope tension balance device.
Background technology
Elevator in use, situations such as such as running into strong wind, earthquake, building often laterally wave.When building shakes
During pendulum, the transverse movement of building is typically converted to install the transverse movement of the rope of elevator device between floors.Rope
The transverse movement of rope can collide to elevator device equipment and/or building, produce noise, elevator components are caused abrasion and
Damage.
In the prior art, the flapping issue of rope is mitigated using certain methods.One kind carrys out restriction rope using mechanical device
Rope, waved with limiting rope.This mechanical structure may effectively limit the lateral oscillation of rope, but cost is higher and takes
Larger space in hoistway.Another method is to limit lift car running situation during building waves period.In elevator system
System sets the sensor that detection building waves.When rocking tendency exceeds predetermined threshold value, control device sends control instruction, example
Stop at the floor that rope waves may occur for the speed of service and/or limitation lift car for such as reducing elevator.These sides
The swing that the defects of this is certain can not suppress elevator rope well all be present in method.
The content of the invention
To overcome the above-mentioned technical problem in existing apparatus, there is provided a kind of to mitigate when waving and detecting that building waves
Excitation to the natural frequency of the plurality of rope, to prevent the plurality of rope from waving and produce resonance, the present invention with building
Adopt the following technical scheme that.
The technical scheme is that：A kind of elevator rope tension balance device, including be arranged on multiple elevator ropes
Fag end shank part, be arranged on tilt detection unit 2 on the fag end shank part, controller 1 and rope tension control
Device, the rope tension controller include displacement transducer 5, hydraulic cylinder 10, spring assembly, hydraulic pump 3 and valve 4；It is described
Tilt detection unit is connected with controller, and the controller is connected with the hydraulic pump, and the hydraulic pump is controlled by the valve 4
The hydraulic cylinder is made to spring assembly applying power.
Preferably：The tilt detection unit is angular transducer.
Preferably：The spring assembly includes spring, screw rod, pressing plate, nut.
Preferably：The controller is CPU.
Preferably：The rope tension controller also includes pressure gauge.
In strong wind or earthquake, when building waves, the natural frequency to the plurality of rope is mitigated by the device
Excitation, with prevent the plurality of rope from waving and with building produce resonance, miscellaneous part, which is caused damage, or safeguarded multiplies
The personal safety of visitor, the apparatus structure is simple, cost is low, portion takes hoistway additional space, small volume, can be widely applied for
In various lift appliances.
Brief description of the drawings
Especially indicate and be distinctly claimed in the claim that specification summarizes at part and be considered as this hair
Bright theme.According to obtaining above and other feature and advantage described in detail below, of the invention with reference to accompanying drawing it is clear that
In the accompanying drawings：
Fig. 1 is elevator rope tension balance device structure chart.
Fig. 2 is spring assembly structure chart.
Embodiment illustrates embodiments of the invention, and advantages and features in an illustrative manner referring to the drawings.
Embodiment
In Fig. 1,2, including the fag end shank part 6 being arranged on multiple elevator ropes, it is arranged on the fag end shank part 6
Tilt detection unit 2, controller 1 and rope tension controller, the rope tension controller include displacement transducer 5,
Hydraulic cylinder 10, spring assembly, hydraulic pump 3 and valve 4；The tilt detection unit is connected with controller, the controller with
The hydraulic pump connection, the hydraulic pump control the hydraulic cylinder to spring assembly applying power, the tension force by the valve 4
Adjuster is operationally communicated with the tilt detection unit 2, and rope tension controller is configured to, when tilt detection unit 2 is examined
When measuring the inclination of the fag end shank part 6, the tension force of multiple ropes is adjusted to control the natural frequency of rope, makes itself and building
The intrinsic frequency of thing differs, and to mitigate the excitation to rope, mitigates waving for rope, so as to suppress the resonance with building；
Angular transducer can be selected in the tilt detection unit, be configured to detect elevator device the fag end shank part 6 inclination with
The change of time, and the information detected is sent into controller, controller is by the inclination conditions detected and predetermined threshold ratio
Compared with during beyond predetermined threshold range, controller just controls hydraulic pump to act, and finally controls hydraulic cylinder to drive spring by valve
Component provides rope different tensile forces, to change the wobble frequency of rope, is not resonated with building.
Hydraulic cylinder 10 in the device can have two groups, and when operating, hydraulic pump pumps fluid from first group of hydraulic cylinder
To second group of hydraulic cylinder.For the rope for being connected to second group of hydraulic cylinder can be increased by increasing the fluid in second group of hydraulic cylinder
Power, while reduce the tension force for the rope for being connected to first group of hydraulic cylinder.First group and second group of hydraulic cylinder can be separated by check valve,
Check valve structure is pumped to second group of hydraulic cylinder into permission fluid from first group of hydraulic cylinder, while prevents fluid from second group of hydraulic pressure
The reverse flow of fluids of cylinder is returned in first group of hydraulic cylinder.
The tilt detection unit in the device is angular transducer；The spring assembly includes spring 7, screw rod 9, pressure
Plate 8, nut；The controller is CPU；The rope tension controller also includes pressure gauge.Pass through the specific choosing of above-mentioned part
Select, can preferably realize the control to rope tension, mitigate the excitation of the natural frequency to the plurality of rope, to prevent that this is more
Individual rope waves and produces resonance with building, the personal safety of passenger is caused damage or safeguarded to miscellaneous part, the dress
Put simple in construction, cost is low, portion take hoistway additional space, small volume, can be widely applied in various lift appliances.
Although the embodiment of combined only limited quantity is to the present invention have been described in detail, but it should easily geographical
Solution, the invention is not restricted to such disclosed embodiment.On the contrary, can be modified to the present invention, do not have before this to combine
Description but any amount of modification, change, replacement or the equivalent arrangements to match with the spirit and scope of the present invention.In addition, though
Multiple embodiments of the present invention are described, it will be understood that, aspect of the invention may include described embodiment
In more only.Therefore, the present invention is not seen as limited by the foregoing description, but is only limited by scope of the following claims
System.
