Damage, keeps cable 104 more smooth when skidding off.Limiting device can be located at the first traction wheel 101 and second in the horizontal direction
Between traction wheel 102, hanging cable 104 can be made shorter, in this way convenient for tightening；In the vertical direction, limiting device can be with
Positioned at the top of the first traction wheel 101, avoids limiting device from influencing cable 104 and excessively led to second from the first traction wheel 101
The track of running wheel 102 makes cable 104 more smooth by coil.
Guide pad 108 can be set on bracket 105, guide pad 108 is sliding relative to bracket 105 along the axial line of spreader 106
Dynamic, column 107 is mounted on guide pad 108.Cable 104 can be reduced in sliding process by reducing the distance between two columns 107
In shaking, to improve efficiency of transmission, and guide pad 108 can be slided with cable 104 along the direction of axis line of spreader 106,
Guarantee that cable 104 all in the centre of two root posts 107, avoids cable 104 and column 107 from generating excessive frictional force at any time.
Two grooves 111 can also be set on guide pad 108, and two grooves 111 are along the direction of axis line interval of spreader 106
It is arranged, is provided with sliding block 113 in groove 111, sliding block 113 is slidably connected with groove 111, and sliding block 113 is in groove 111 along spreader
106 direction of axis line slides, and is respectively arranged with reset spring 112 in two grooves 111, reset spring 112 enables two root posts
107 have movement tendency adjacent to each other.It is closer that reset spring 112 can allow two root posts 107 to be leaned on, and allows column 107 to cable
104 generate suitable extruding force, reduce the shaking of cable 104 with this, make the more compact of coil panel.
Wherein it is possible to which two reset springs 112 in elongation state are arranged, two are divided in elongation state reset spring 112
Wei Yu not be in two grooves 111, and two are respectively positioned between two root posts 107 in the reset spring 112 of elongation state, due to multiple
Position spring 112 is in elongation state, therefore can give 104 1 pulling force of column, makes two root posts 107 that there is movement adjacent to each other to become
Gesture；Or setting two reset springs 112 in compressive state, two are located at two in the reset spring 112 of compressive state
The two sides of root post 107 can give column 107 1 thrusts, have two root posts 107 in the reset spring 112 of compressive state
Movement tendency close to each other.Certainly, mode in the set-up mode of reset spring 112 more than above-mentioned two, is also possible in pressure
The sum of contracting state cooperates in the reset spring 112 of elongation state or other modes.
Hitch frame further includes power device 110, and power device 110 is mounted in rack 103, the output of power device 110
End is connect with the first traction wheel 101, and power device 110 is for driving the first traction wheel 101 to rotate around its axial line.Power device
110 directly drive the first traction wheel 101, realize full automatic mechanical in disk line in this way, reduce the working strength of worker.
Sliding slot 114 and link block 115, sliding slot can also be arranged in the part that the second traction wheel 102 is used to support in rack 103
114 along the center of circle in the center of circle and the second traction wheel 102 of the first traction wheel 101 connecting line extend, the recess direction of sliding slot 114 with
The direction of axis line of second traction wheel 102 is parallel, and one end and the sliding slot 114 of link block 115 are slidably connected, and link block 115 is along cunning
The extending direction of slot 114 slides；The other end of link block 115 and the second traction wheel 102 are rotatablely connected, and are also set up in sliding slot 114
There is spring 116, spring 116 enables the second traction wheel 102 have the trend far from the first traction wheel 101.Cable 104 is wound on two simultaneously
On a traction wheel, cable 104 gives two traction wheels, one tightening force, allows two traction wheels to have the tendency that close, and 116 meeting of spring
So that the second traction wheel 102 is had the tendency that one at any time far from the first traction wheel 101, tightens power to increase, cable 104 is stretched tight
It is tighter, avoid cable from shaking.
Wherein it is possible to be the spring 116 in link block 115 close to the setting of the side of the first traction wheel 101 in compressive state,
It can give the second traction wheel 102 1 thrusts in the spring 116 of compressive state, there is the second traction wheel 102 far from the first traction
The trend of wheel 101；Or it is drawn in side setting of the link block 115 far from the first traction wheel 101 in the spring 116 of tensional state
The spring 116 for stretching state can give the second traction wheel 102 1 pulling force, have the second traction wheel 102 far from the first traction wheel 101
Trend.Certainly, spring 116 is located in sliding slot 114.
The diameter of first traction wheel is greater than the diameter of the second traction wheel.When the diameter difference of two traction wheels, cable with compared with
The contact of big traction wheel is more, and power device is to connect with the first traction introduction, therefore make the transmission of cable faster,
It is more steady, improve the efficiency of disk line.
Helicla flute can be set on first traction wheel 101, helicla flute is located on the periphery of the first traction wheel 101, spiral
Slot along the first traction wheel 101 axial line in the shape of a spiral；Helicla flute is provided on second traction wheel 102, helicla flute is located at second
On the periphery of traction wheel 102, helicla flute along the second traction wheel 102 direction of axis line in the shape of a spiral, and the second traction wheel 102
On helicla flute rotation direction it is identical as the rotation direction of helicla flute on the first traction wheel 101.Cable 104 is in the helicla flute on traction wheel
The other side that traction wheel is slowly shifted to by the side of traction wheel, in moving process, cable 104 closely connects with traction wheel always
Touching, helicla flute is avoided that slipping phenomenon occurs when traversing on traction wheel for cable 104, to guarantee the orderly quilt of cable 104
It transfers out and carries out disk line.The first traction wheel 101 is identical with the rotation direction of the helicla flute of the second traction wheel 102 simultaneously, therefore cable
104 can synchronize from side on two traction wheels and shift to the other side.
The axial line of the axial line of first traction wheel 101 and the second traction wheel 102 can be in same horizontal line.The
When one traction wheel 101 and the second traction wheel 102 are located in same horizontal line, power device 110 disappears when driving the first traction wheel 101
The power of consumption is minimum.
First traction wheel 101 is provided with ribs 109, and the second traction wheel 109 is also equipped with ribs.It is passed in cable 104
During defeated, ribs is arranged all by by the huge pressure towards the center of circle in the first traction wheel 101 and the second traction wheel 102
After 109, the intensity of the first traction wheel 101 and the second traction wheel 102 can increase, to increase its service life.
In conclusion hitch frame provided by the invention setting is there are two traction wheel, cable bypasses two traction wheels simultaneously, two
Root traction wheel can tighten cable, tense cable without manually going, and limiting device can limit the scope of activities of cable, in this way
The coil that disk goes out is more compact, the cable small volume of equal length and weight, transports more convenient, and the amount of working at the same time is also significantly
It reduces.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
