Description
Technical field
The present invention relates to a kind of use many steel wire ropes make lift car and balance weight lifting elevator.
Background technology
The steel wire rope that elevator is used uses by the structure of many steel wire twisteds.In elevator, adopt
Being connected with lift car with one end of steel wire rope, the other end is connected with balance weight, by hoist engine to steel
Cord is driven, and thus makes the structure that lift car lifts, or uses the two ends of steel wire rope solid
It is scheduled on the top of building, lift car and balance weight are respectively provided with pulley, make steel wire rope pass through
Pulley and form movable pulley, thus make lift car and balance weight lifting structure.No matter which uses
Plant structure, when lift car lifts, steel wire rope alternating bending when acting on tensioned.Cause
This, in use, along with the accumulation that steel wire is tired, cause steel wire to rupture successively.At steel
The number of breaks of silk is when having exceeded specified quantity, it is judged that terminate the service life for steel wire rope and to steel wire
Rope is replaced.
When more change steel rope, need to make elevator stop, and hang elevator car with other lifting devices
Steel wire rope can be removed behind railway carriage or compartment.When the replacing operation of steel wire rope not only needs to spend substantial amounts of operation
Between, and during more change steel rope, elevator can not use, so can make troubles to passenger.
It is therefore preferable that the replacement cycle of steel wire rope can be extended, to reduce the replacing number of times of steel wire rope.
As it has been described above, the service life of steel wire rope is determined by the degree of fatigue of steel wire, and act on steel wire
Tension force on rope is the biggest, and steel wire is more susceptible to fatigue.Many steel are generally used in common elevator
Cord, in many steel wire ropes, if having other steel wire ropes height of warp tension ratio of specific steel wire rope, then
The service life of this steel wire rope can be shorter than other steel wire rope.Due to the tension force between many steel wire ropes
Unbalanced meeting causes shorten the service life of specific steel wire rope, so needing periodically to open steel wire rope
Power checks, in order to by the tension adjustment uniformly tension force of each steel wire rope.
When adjusting the tension force of steel wire rope, can use and change the length of steel wire rope or change steel wire rope
The method of fixed position.When changing the length of steel wire rope, need temporarily with other steel wire rope etc.
Suspend lift car in midair.Owing to this operation requires a great deal of time, adjust steel so generally using
The method of the fixed position of cord adjusts the tension force of steel wire rope.In order to adjust the fixed bit of steel wire rope
Putting, connecting in the end of steel wire rope has rod member.Additionally, be provided with threaded portion in Rod end, and

Pedestal or supporting member or the beam etc. of thing contact.When adjusting the tension force of steel wire rope, make
Nut location on rod member moves, and thus changes the distance between pedestal and steel wire rope.
, produce on a steel cord tensioned in the case of, according to the difference of twisted method, sometimes
Turning moment can be produced, when this turning moment is delivered to the rod member being connected with steel wire rope, make rod member occur
Rotate.Additionally, this turning moment acts on rod member to the rubbing surface of multiple contact portions of pedestal,
Make to produce at these rubbing surfaces to rotate against.Now, if between each contact portion frictional force big and
Can offset turning moment, then rod member will not rotate, and if frictional force is little and can not offset rotation
During torque, then rod member can rotate.Frictional force can eliminate (counteracting) great turning moment and
Rod member is maintained at not rotation status, depends on the apparent condition of contact portion, due to each contact portion
Apparent condition between difference big, so the size of turning moment that each component can be offset is the most each
Differ.Therefore, even if the tension force of steel wire rope is identical, also there will be only specific steel wire rope and occur
Situation about rotating.
Cause twisted to unclamp at wire rope rotating after, steel wire rope can extend.Opening at many steel wire ropes
Try hard to keep and hold under consistent state, when steel cable therein extends because rotating, with other
Steel wire rope is compared, and this root steel wire rope is in the state of specific elongation.Now, the tension force of this root steel wire rope
Decline so that the tension force that other steel wire ropes are born increases.So, can cause due to wire rope rotating
Tension force generation deviation, so having been disclosed for the structure for preventing wire rope rotating.
Proposing a kind of elevator in patent documentation 1, this elevator have employed in the end with steel wire rope even
Installation fitting on the rod member connect, and knot accessory being joined to one another by the union body of steel wire etc.
