Description
Technical field
Elevator technical field is the utility model is related to, particularly relates to a kind of elevator rolling wheel around rope structure.
Background technology
The drawstring of traditional elevator is directly wound in the outside of rolling wheel, in order to keep drawstring not skidded on rolling wheel, needs
Wind many circles and carry out increasing friction force, therefore need to set many circle helicla flutes on rolling wheel, and the size of rolling wheel is bigger,
Weight and materials are also more, therefore manufacturing cost is higher.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of elevator rolling wheel around rope structure, greatly reduces spiral shell
The number of turns of spin slot, reduce the size of rolling wheel.
The utility model in order to solve its technical problem used by technical scheme be：A kind of elevator rolling wheel is around knot
Structure, including rolling wheel, the lateral surface of the rolling wheel is provided with some spiral helicine grooves of circle, drawstring is wound with the groove, described
An inclined hole is provided between the beginning and end of the groove on rolling wheel, the middle part of the drawstring is worn from the inclined hole,
Centre position of the both ends of the drawstring respectively from the beginning and end of the groove along the groove to groove winds backward phase
Opposite direction is stretched out.
As further improvement of the utility model, the rolling wheel is fixed on main shaft, and the both ends of the drawstring are set respectively
There is the joint withheld, be additionally provided with pull bar, the both ends of the pull bar are respectively fixed with bearing pin, the joint difference at the drawstring both ends
Fixed by being thread through after the circular hole set on the bearing pin by tensioning nut.
As further improvement of the utility model, the drawstring is steel wire rope.
As further improvement of the utility model, the axle of straight line and the rolling wheel where the beginning and end of the groove
Line is not parallel.
As further improvement of the utility model, the angle between inclined hole and the rolling wheel axis is 55-60 degree.
The beneficial effects of the utility model are：The elevator is worn with drawstring of the rolling wheel around rope structure from the inclined hole of rolling wheel
Cross, then on rolling wheel wind when produce two knuckles, can great increasing friction force, prevent drawstring from being skidded along rolling wheel, so
The number of turns of helicla flute on rolling wheel can be reduced, reduce the size of rolling wheel, and then reduce the size of equipment, reduce equipment materials and
Weight, manufacturing cost is reduced, and application scenario is further widened.

Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But guarantor of the present utility model
Shield scope is not limited to following embodiments, i.e., is made in every case with present utility model application the scope of the claims and description simple
Equivalent changes and modifications, all still belong within the utility model patent covering scope.
It is a kind of elevator rolling wheel described in the utility model around rope structure, including rolling wheel 1, the rolling wheel refering to Fig. 1-2
Lateral surface be provided with the spiral helicine grooves 2 of some circles, drawstring 3 is wound with groove 2, drawstring can be steel wire rope etc..Wherein, ditch
The axis of straight line and rolling wheel where the beginning and end of groove is not parallel (i.e. the number of turns of spiral groove is not whole circle), and in groove
Starting point 21 and terminal 22 between be provided with an inclined hole 4, the middle part of drawstring 3 is worn from inclined hole 4, and the both ends of drawstring 3 are respectively from ditch
The beginning and end of groove 2 is stretched out round about after the centre position winding along groove 2 to groove 2.
For easy making process, while inclined hole is not passed through spool centre bore, and and can makes drawstring produce maximum friction after winding
Power, the angle of the inclined hole (line of the Origin And Destination of groove) between rolling wheel axis is arranged to 55-60 degree, so drawn
It is not arc transition after rope is wound after being passed in inclined hole on rolling wheel, and has a unexpected bending, it is very big so as to produce
Frictional force.
The elevator with rolling wheel around rope structure rolling wheel when being rotated under main shaft or other external force drive, one end of drawstring exists
What the number of turns reduction wound on rolling wheel, the number of turns increase that other end is wound on rolling wheel, and drawstring reduced on rolling wheel one end
The winding number of turns is equal to the other end increased winding number of turns, exactly track that drawstring was wound on groove, the other end on rolling wheel
The track (i.e. one side serving, one side slack rope) of release.
Refering to Fig. 3-4, the use state diagram for the rolling wheel around rope structure, wherein rolling wheel are fixed on main shaft 5, by leading
Axle drives rolling wheel rotation.The both ends stretched out after drawstring winding rolling wheel are respectively equipped with the joint 6 withheld.It is additionally provided with pull bar 7, push-and-pull
The both ends of bar are respectively fixed with bearing pin 8, the joint at drawstring both ends respectively by external screw thread through after the circular hole set on bearing pin by
Tensioning nut 9 is fixed.When main shaft rotates, unwinding action is done in drawstring both ends with rolling wheel, and drawstring passes through toward the one end wound on rolling wheel
The transmission tractive force of bearing pin is to pull bar, so as to drive pull bar to push or pull on what guiding 11 of the load 10 along pull bar constrained
Direction is moved, i.e., the rotary motion of rolling wheel is converted into the linear motion of pull bar by drawstring, and the movement conversion mechanism can answer extensively
With the mechanism or equipment for needing to be converted to (forward and reverse) rotary motion (reciprocal) linear motion, including but not limited to elevator,
Hoist engine etc..
As can be seen here, the elevator is passed through with drawstring of the rolling wheel around rope structure from the inclined hole of rolling wheel, then is twined on rolling wheel
Around when produce two knuckles, can great increasing friction force, prevent drawstring from being skidded along rolling wheel, can so reduce spiral shell on rolling wheel
The number of turns of spin slot, the size of rolling wheel is reduced, and then reduce the size of equipment, reduced equipment materials and weight, reduction are manufactured into
This, and application scenario is further widened.
