Description
Technical field
The present invention relates to a kind of fixed pulley, and in particular to the stronger pulley structure of anti-wear performance.
Background technology
The function of fixed pulley is to change the direction of power, but can not be laborsaving.When pulling weight, fixed pulley can be used to exert a force
Direction is changed into the direction easily contributed.Fixed pulley spacing of the prior art is more fixed, it is impossible to is carried out with all ropes
Matching, when traction rope is shorter relative to pulley shaft length so that when using fixed pulley, with the moving process of object
The swing of center of gravity, traction rope also with swing, can cause the axially contact point of rope and fixed pulley changing always so that rope
The frictional force of son and fixed pulley increases, easy wear and rupture, and service life is shorter.
Suspension hook structure of the prior art is also more single, typically an only radian, when the bar for hanging over different thicknesses or
When restricting on body, with the swing of suspension hook bottom load-bearing material, suspension hook also can cause the axially contact of suspension hook and bar or rope with swing
Point is changing always so that the frictional force that suspension hook is subject to is increasing, and easily abrasion, influences its service life.
The content of the invention
It is an object of the invention to provide the stronger pulley structure of anti-wear performance, realizes that one kind is applicable to different thicknesses and led
It the purpose of the fixed pulley of messenger, can effectively avoid pull rope in distraction procedure the problem of easy abrasion, while solve existing skill
Suspension hook in art easily moves with steel wire rope, easily abrasion so that the problem of service life is shorter.
The present invention is achieved through the following technical solutions：
The stronger pulley structure of anti-wear performance, including rotating shaft, coupler body, pulley base is respectively arranged with rotating shaft both ends, two
Two ring baffles are additionally provided between individual pulley base, the ring baffle can move axially along the axis of rotating shaft, in rotating shaft
Also it is cased with two springs, the side plate face of the both ends of each spring respectively with pulley base, ring baffle is fixed, in two annular gears
Plate is all provided with several circular grooves on two faces relative to each other, and several circular grooves circularize setting around the shaft, every
It is provided with ball in individual circular groove, the central point of ball is equal to the radius of ball to the vertical range of rotating shaft, in addition to
The shrouding that the plate face of ring baffle is mutually matched, several circular holes are provided with shrouding, several circular holes and circular groove are one by one
Corresponding, the part surface of the ball is prominent from circular orifices and is limited in circular groove and the semiclosed cavity in shrouding besieged city
It is interior；
The coupler body includes intrados and extrados, one-level deep-slotted chip breaker is provided with the intrados of coupler body, in one-level deep-slotted chip breaker
Inner concave be provided with two level deep-slotted chip breaker, the arc length of the one-level deep-slotted chip breaker is more than the arc length of two level deep-slotted chip breaker, in one-level deep-slotted chip breaker
Rubber layer is also uniformly posted with the inwall of two level deep-slotted chip breaker.Further, for above technical problem, the present invention is to existing
Fixed pulley is improved, first in the rotating shaft of fixed pulley increase limit is formed between two ring baffles by two ring baffles
Bit port, to reduce the operating range of rope, reduce its wear rate.Spring is set between ring baffle and pulley base, passed through
The flexible or stretching of spring, the width of adjustable limit passage, to adapt to the rope of different thicknesses, further avoids rope from being shaken
Move and produce displacement, improve the scope of application and practicality of the present invention.Ball is set on each ring baffle, in ball
Heart point is equal to the radius of ball to the vertical range of rotating shaft, can so ensure rope and ball contact, because ball can seal half
Close in cavity and freely rotate, when pulling rope, frictional force is produced between rope and ball, drive what ball pulled towards rope
Direction is moved, and now, ball can play a part of the transmission of auxiliary pushing rope, compared with prior art, reach certain laborsaving mesh
's.
Secondly, two arc length grooves are provided with the intrados of suspension hook, two deep-slotted chip breakers it is of different sizes, be applicable to different thick
Thin rope or the body of rod, when suspension hook is shaken, rope or the body of rod can be stuck in one-level deep-slotted chip breaker or two level deep-slotted chip breaker, reduce
The probability of suspension hook one end, the setting of rubber layer can not only be played a part of protecting suspension hook, can also further avoid suspension hook and rope
Or moved axially between the body of rod, can solve suspension hook of the prior art with this easily moves with rope body, easily abrasion so that
The problem of service life is shorter.
The ball is steel ball.Steel ball is not easy to get rusty, and service life is longer and relatively smooth, can play protection rope well
The effect of son.
Preferably, the ring baffle and shrouding are made of stainless steel plate.Stainless steel plate is not easy to get rusty, service life compared with
It is long.
The present invention compared with prior art, has the following advantages and advantages：
The stronger pulley structure of anti-wear performance of the present invention, realize a kind of fixed pulley for being applicable to different thicknesses pull rope
Purpose, can effectively avoid pull rope in distraction procedure easily abrasion the problem of, while solve suspension hook of the prior art
Easily moved with steel wire rope, easily abrasion so that the problem of service life is shorter.
