Detailed description of the invention
Fig. 1 is general structure schematic diagram of the invention；
Fig. 2 is top view of the invention.
Specific embodiment
The present invention provides a kind of elevator traction rope tension self balancing devices, below with reference to the structural schematic diagram of Fig. 1, to this
Invention is illustrated.
As shown in Figure 1, a kind of elevator traction rope tension self balancing device provided by the invention, including it is separately positioned on car top
With the semicircle annular groove ontology 1 of 3 center of upper beam of counterweight, the semicircle annular groove ontology 1 passes through locking apparatus with upper beam 3
4 are fixedly connected, and buffer unit 2 is arranged between the semicircle annular groove ontology 1 and upper beam 3, opens up on the semicircle annular groove ontology 1
There is hole slot combined structure, the hole slot combined structure includes even number mounting hole 11, and every two mounting hole 11 is one group successively suitable
Sequence arranges, and offers semicircle annular groove between every two mounting hole 11；Adjusting rope 5, the adjusting are equipped in the semicircle annular groove
The both ends of rope 5 pass through attachment device 7 respectively and connect with hoist ropes 1 and hoist ropes 29, the lower end setting of the attachment device 7
There is limit alarm device.
Further, the locking apparatus 4 is one kind of holding screw or bolt.
Further, the buffer unit 2 is rubber pad.
Further, the attachment device 7 is bidirectional joint, and the bidirectional joint includes two and positioned opposite unidirectionally connects
Head, the mode that two one-way joints are connected or welded with screw are fixedly connected.
Further, the limit alarm device includes adjusting 5 both ends of rope to wear fixed postive stop baffle 6 respectively, each
The lower section of postive stop baffle 6, which is provided with, corresponds matched limit switch 10 with postive stop baffle 6, and the limit switch 10 is fixed
In 1 upper surface of semicircle annular groove ontology, and limit switch 10 is electrically connected with elevator safety alarm circuit.
The present invention is made of two parts：
First part is the semicircle annular groove that low friction is wriggled, and semicircle annular groove internal diameter is slightly larger than adjusting rope diameter, semicircle annular groove
Not less than adjusting rope 15 times of diameter, semicircle annular groove ontology has to prevent from adjusting rope and fall off and prevent foreign matter from entering to be set pitch diameter
It applies.
Second part is flexible lever formula balance adjustment rope, and the adjusting rope uses Special elevator steel wire rope, and it is straight to adjust rope
Diameter is greater than one standard value of hoist ropes, and the adjusting rope is connected by attachment device with hoist ropes；The postive stop baffle can be with
It prevents a hoist ropes from falling off or an other hoist ropes is caused to fail when being broken.
Wherein, one end of the bidirectional joint is linked in such a way that babbit pours with adjusting rope, and the other end utilizes
Wedge-type tensioner mode is connected with hoist ropes.
Wherein, the extended line of hoist ropes and adjusting rope is overlapped with the center line of mounting hole 11.
Wherein, hole slot combined structure, including even number through hole 11, every two through hole 11 are one group and successively sequentially arrange
It arranges, offers semicircle annular groove between every two through hole 11.More traditional hoist ropes are connected to become one by multiple adjustings rope
The different monoblock type hoist ropes of Gent adjusts rope and is laid in semicircle annular groove, and the two ends of monoblock type hoist ropes utilize traditional list
It combines, is mounted in through hole 11 to rope end.The structure type of hole slot unification, it can meet the needs of installation and adjustment rope, also
The first and last section of whole hoist ropes can be installed.
In actual use, the process of traction rope tension automatic adjustment is as follows：
If tension is uneven between hoist ropes, the adjusting rope of the big hoist ropes of tension through the invention passes to tension difference
The small hoist ropes of tension adjusts rope with the starting, operation and braking of elevator using the low friction characteristic of semicircle annular groove with compacted
Dynamic form eliminates the tension difference of hoist ropes, achievees the purpose that hoist ropes balancing tension.
In conclusion a kind of elevator traction rope tension self balancing device provided by the invention, it can be automatically to hoist ropes
Power is detected and is adjusted, and compares for existing artificial detection and adjustment, has adjust automatically, laborsaving time saving, high-efficient, smart
Spend the features such as high.
The present invention provides a kind of elevator traction rope tension self balancing device, is adjusted using semicircle annular groove and flexible lever formula balance
Save principle, meet more hoist ropes it is mutually indepedent on the basis of, using bidirectional joint, by more hoist ropes be linked as one it is whole
Body, realizes the adjust automatically of traction rope tension, and remains the balancing tension between hoist ropes, is improving traction rope tension
While Adjustment precision, the labor intensity of manual inspection, measurement and adjustment is greatly reduced, and the device runs elevator
More steady and energy conservation effectively extends the service life of elevator, and the long-term safety operation of elevator has also obtained practical guarantee, real
It is good with property, it is worthy to be popularized.
Disclosed above is only preferable specific embodiment of the invention, and still, the embodiment of the present invention is not limited to this,
What anyone skilled in the art can be thought variation should all fall into protection scope of the present invention.
