150 are rotatably coupled；The free end of swing arm 150 is connect by axis pin 152 with bearing 170, and bearing 170 is used for and mast 210
Connection.
Specifically, link 110 includes two stripe boards being oppositely arranged, and pulley 120 is arranged between two stripe boards,
And it is rotatablely connected by axis pin 152 and two stripe boards.The other end of two stripe boards is provided with connecting seat 130, connecting seat 130
It is that the tubular structure that welding is formed is enclosed by steel plate, steel plate is enclosed accommodating space 132, the setting of 132 opening of accommodating space
There are the sealing plate 134 of circular ring shape, sealing plate 134 to block opening portion；The through-hole at the middle part of sealing plate 134 is passed through for swing arm 150.
Such as Fig. 2 and Fig. 3, revolving support 140 is arranged in accommodating space 132 comprising the first 141, second turns of turning collar
Moving-coil 142 and rolling element.Second turning collar 142 is set on the first turning collar 141, the first turning collar 141 by rolling element with
Second turning collar 142 is rotatably coupled.In the present embodiment, rolling element is spherical shape, and in other embodiments, rolling element can be with
It is cylindric or coniform.
If the external peripheral surface of Fig. 4, the first turning collar 141 are provided with the first card slot, the first card slot prolongs along external peripheral surface
It stretches closed and circularizes groove-like structure, force bearing ring 160 is provided in the first card slot.The inner circumferential surface of second turning collar 142 is set
It is equipped with the second card slot, the second card slot extends closed along inner circumferential surface and circularizes groove-like structure, is equally arranged in the second card slot
There is force bearing ring 160.Wherein, the end abutment of the separate sealing plate 134 of the force bearing ring 160 in the first card slot and the second turning collar 142,
The end abutment of force bearing ring 160 and the first turning collar 141 in second card slot close to sealing plate 134.
By above-mentioned design make the first turning collar 141 relative to the second turning collar 142 axis direction degree of freedom quilt
Limitation, when having axial force between the two, force bearing ring 160 bears axial force, to which rolling element stress is smaller, and can keep away
Exempt from the first turning collar 141 causes the two to detach with the axial relative movement of the second turning collar 142.
Such as Fig. 3 and Fig. 4, swing arm 150 includes first end and second end, and first end is provided with circular connecting plate 155, is connected
Multiple bolts hole are provided on plate 155, connecting plate 155 is connected by the one end of bolt and the first turning collar 141 far from sealing plate 134
It connects.The second end of swing arm is provided with axis pin 152, and swing arm is connect by axis pin 152 with connecting seat 130；And the axis of axis pin 152
Direction is parallel with the direction of 120 central plane of pulley.The setting of axis pin 152 makes swing arm 150 when by external force, can carry out
The swing of certain angle.
It 100 operation principle of wire line guide provided in this embodiment and has the beneficial effect that：
When the central plane of pulley 120 is deviateed at the point of contact of steel wire rope and winding drum 220, the folder of steel wire rope and central plane
Angle is larger, and there is the pulling force of steel wire rope the component perpendicular to central plane, the component to make the wraparound together of pulley 120 and supporting rack
The axis for turning support 140 rotates by a certain angle, and swing arm 150 is rotated by a certain angle around axis pin 152, when entire steel wire rope
When guider 100 reaches equilibrium state, swing arm 150 stops operating with supporting rack.It therefore, can be effectively by above-mentioned design
Reduce steel wire rope and takes turns the frictional force between groove sidewall, the service life for preventing eccentric wear, improving steel wire rope and pulley 120.
In addition, since revolving support 140 is arranged in the accommodating space 132 of connecting seat 130, connecting seat 130 not only rises
To connection function, protective action also is played to revolving support 140.Also, since the second turning collar 142 connect use with sealing plate 134
Bolt and the bolt that is connect with the first turning collar 141 of connecting plate 155 of swing arm 150 primarily serve connection function,
When having pulling force between swing arm 150 and link 110, above-mentioned bolt is not subject to pulling force, therefore bolt is less likely to be damaged；To carry
The high service life of entire wire line guide 100.
It should be noted that the present embodiment is one kind of the numerous embodiments of the utility model, and in other embodiments, revolution
Support 140 can use thrust bearing, i.e. end face between the end face of the first turning collar 141 and the second turning collar 142 to be oppositely arranged,
Rolling element is arranged between above-mentioned two end face；At this point it is possible to be not provided with force bearing ring 160.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
