Description

Lift appliance
Technical field
The present invention relates to lift appliances.
Background technique
Traction elevator device be using positioned at traction race hoist ropes and traction race frictional force, be drivingly connected in The carriage and counterweight at hoist ropes both ends are run up and down.When elevator is run, the length of the hoist ropes of cage side and counterweight-side is continuous Variation.For the long stroke elevator of skyscraper, the length and weight of hoist ropes are all very big.So according to carriage and right The position of weight, when the hoist ropes of traction sheave side is considerably longer than the other side, two side load of traction sheave can generate serious injustice Weighing apparatus, makes elevator be difficult to realize stable operation.It is poor in order to reduce the load that traction sheave two sides are born in elevator operation, elevator dress It sets and is typically provided with compensation device.Common compensation device is mainly made of compensation rope and tensioning wheel.One end connection of compensation rope In carriage, the other end is connected to counterweight, and in the sag bent portion of compensation rope equipped with tensioning wheel.Related content is referred to " elevator-principle installation and maintenance " Section nine of chapter 2<compensation device>(Shanghai City elevator industry association, Shanghai City elevator Training center writes;China Textiles Press's distribution;November the 1st edition in 2011).
In addition, lift appliance usually has limiter of speed, for monitoring the speed of service of elevator.Limiter of speed includes limiter of speed sheet Body, governor rope and tensioning wheel etc..Governor rope and it is mounted on carriage or counterweight (below for sake of convenience, only enumerating carriage) Push and pull system be connected, moved together in common operational process with carriage.When the decrease speed of carriage is more than specified When speed, limiter of speed ontology is by stop governor rope, to drive the safety tongs being mounted below carriage dynamic by push and pull system Make, by force stop carriage.Related content is referred to above-mentioned " elevator-principle installation and maintenance " Section five < speed limit of chapter 2 Device, safety tongs and carriage protection device for over-speed ascending >.
Whether the tensioning wheel of the tensioning wheel or limiter of speed of compensation device is all that compensation rope or speed limit are kept by its gravity The tensioning state of device rope.When the weight deficiency of tensioning wheel, such as Fig. 2-40 institute of above-mentioned " elevator-principle installation and maintenance " Show, hangs counterweight (hereinafter referred to as " hang down weight ") from above, in the rotary shaft of tensioning wheel often to increase the gravity of tensioning.
Safety tongs acts during elevator downlink, when carriage is by urgent stop, counterweight, hoist ropes, compensation rope and limit Fast device rope will all be retracted, this will drive tensioning wheel under the action of inertia force after moving a distance to original moving direction It rebounds.The stroke of elevator is longer, and the length of compensation rope and governor rope is longer, causes the amplitude of jump that will get over Greatly.When the amplitude of this jump is larger, the not only possible injury compensation rope of the tensioning wheel fallen after rise after jump or governor rope, and It may cause tensioning wheel and be detached from compensation rope or governor rope.
The simplest method for inhibiting this jump is to increase the vertical weight being suspended in tensioning wheel rotary shaft, large-scale vertical weight The inertia of counterweight, hoist ropes, compensation rope and governor rope can be inhibited mobile, to inhibit the jump of tensioning wheel.But such as Fruit increases the vertical weight of compensation device, must increase the radical of hoist ropes to bear these weight.For long stroke elevator, The weight of hoist ropes accounts for very big specific gravity, and the quantity for increasing hoist ropes will increase the burden of traction machine, needs to improve when necessary The specification of traction machine, while the specification for being also required to improve control cabinet matches with it.Equally, if increasing the vertical weight of limiter of speed, it is Its load is born to be also required to improve the specification of limiter of speed.These devices will also become larger with its size of the raising of specification, in order to These devices are accommodated, need to increase the size of computer room when necessary.These will all increase substantially the cost of lift appliance.
In addition, hoist ropes and compensation rope can be elongated gradually in use, this will make the tensioning wheel of compensation device Height also reduces gradually therewith.If the minimum point (such as the lower end for the weight that hangs down) of the strainer of compensation device contacts hoistway bottom Portion, then the strainer will lose tension effects.In order to avoid this kind of situation, it needs to guarantee compensation when assembling elevator Spacing between the minimum point and shaft bottom of the strainer of device is not less than defined distance, and needs periodic detection and tune The whole spacing.As the size of the weight for increasing the weight that hangs down, the weight that hangs down also will increase.It is done in order to avoid hanging down weight with the mutual of peripheral devices It relates to, the weight for increasing the weight that hangs down is usually to be realized by increasing the height for the weight that hangs down.And in order to guarantee the vertical weight after increase height The distance between minimum point and shaft bottom are not less than defined distance, then the depth for needing to increase pit (it is whole to increase hoistway The height of body).This will not only increase substantially the cost of lift appliance, but also be difficult to realize under the limitation of fabric structure.
Japanese Unexamined Patent Publication 5-338958 discloses another elevator that tensioning wheel can be inhibited to jump and mends Repay rope tensioner apparatus.This device is set in the two sides of tensioning wheel there are two oil cylinder, two in-oil cylinder pistons item flexible The connection of shape body, the middle part of the strip shape body are hung on the frame of tensioning wheel.When tensioning wheel moves up, will be drawn by strip shape body Piston, and in-oil cylinder viscous oil will prevent the movement of piston, the resistance of the mobile faster viscous oil of speed of tensioning wheel is more Greatly, so as to inhibiting the jump of tensioning wheel.I.e. oil cylinder and piston constitute a kind of buffer gear.
But tensioning wheel can generate very big power when rebounding, for the jump for overcoming this power to inhibit tensioning wheel Jump, piston and oil cylinder require very big basal area.In addition, tensioning wheel height reduces if hoist ropes and compensation rope are elongated, Piston is set to fall on the bottom of oil cylinder, then the device will lose the effect for inhibiting tensioning wheel jump.Such case occurs in order to prevent, Oil cylinder needs biggish length again.In other words, which needs the oil cylinder and piston of big specification, this will increase substantially elevator dress The cost set.In addition, the power that tensioning wheel rebounds will act on the shaft bottom for fixing the oil cylinder by oil cylinder.In order to prevent The breakage of the fixed part, it is necessary to reinforce the intensity of shaft bottom He the fixed part.This also by increase substantially lift appliance at This.Moreover, because the reinforcing of shaft bottom is difficult to realize on existing lift appliance, so this buffer gear is difficult to add Into existing lift appliance.
Summary of the invention
It, can be with simple ground structure and lower technical problem to be solved by the invention is to provide a kind of lift appliance Cost-effectively inhibit the jump of compensation rope tensioning wheel.
To solve the technical problem, lift appliance of the invention includes: hoistway;It goes up and down in the carriage of the hoistway;It is logical Cross the counterweight that hoist ropes is connected with the carriage;Drive the traction machine of the carriage;With compensation rope and rope tensioning wheel is compensated, For balancing the compensation device of two lateral load of traction sheave;And the limiter of speed with governor rope and governor tension pulley.It is described Compensation device includes: first tensioning vertical weight of the hanging in the rotary shaft of the compensation rope tensioning wheel;It is arranged at described first Shaft bottom below tight vertical weight, middle part have can make the vertical through-hole passed through again of the first tensioning first additional vertical Weight;And connection described first is tensioned the first flexible rope of hang down weight and the first additional vertical weight.It is described in usual operation First flexible rope is in relaxed state, and the described first additional gravity for hanging down weight will not act on the compensation rope tensioning wheel. When operation is abnormal, and the compensation rope tensioning wheel is caused to rebound, first tensioning jumped therewith is hung down and will be passed through again The first additional weight that hangs down described in the first flexible rope pull-up, makes the described first additional gravity for hanging down weight restrict in the compensation On tensioning wheel, inhibit the jump of the compensation rope tensioning wheel.
Since lift appliance of the present invention is in usual operation, the first flexible rope is in relaxed state, the first additional weight that hangs down Gravity will not act on compensation rope tensioning wheel, so do not need because the first additional weight that hangs down there are due to increase the number of hoist ropes Amount does not need the specification for improving traction machine and control cabinet, does not need the size for increasing computer room, does not need to increase substantially elevator dress The cost set.And when elevator operation, which is abnormal, causes compensation rope tensioning wheel to rebound, the first flexible rope for being tightened up It can make the gravity of the first additional weight that hangs down on compensation rope tensioning wheel, to effectively inhibit the jump of compensation rope tensioning wheel Jump.
In addition, the vertical through-hole passed through again of the first tensioning can be made since the middle part of the first additional vertical weight has, so, to the greatest extent Pipe first, which adds to hang down to reseting to set, also can guarantee that the lower section of the vertical weight of the first tensioning has enough skies in the lower section of the vertical weight of the first tensioning Between.When hoist ropes and compensation rope be elongated, compensation rope tensioning wheel height decline when, will not because first tensioning hang down weight lower end with First additional vertical heavy phase contacts and loses tension effects.
