Embodiment
To make those skilled in the art be better understood from technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
Formula elaborates to the present invention.
As depicted in figs. 1 and 2, one embodiment of the present of invention discloses a kind of cable tensioner, and it is used for cable
There is provided certain tensioning, the cable tensioner specifically include base 10, adapter sleeve 20, tensioning wheel 40, rocking arm 32, connecting rod 50 with
And two stage clip.Base 10 is fixed on fixed pedestal, is such as fixed on the stainless steel strut of electric pole.Adapter sleeve 20 is horizontal in base
On 10, i.e. the axis of adapter sleeve 20 is parallel to the ground.Crank arm 31 one end passes through adapter sleeve 20, crank arm 31 other end installing
Bearing up pulley 40.The wheel face of tensioning wheel 40 is used to store cable and produces thrust necessarily radially to cable so that cable is in tensioning
State.The afterbody of rocking arm 32 31 is fixedly connected with cranking arm through one end of adapter sleeve 20, so that rocking arm 32 can be with cranking arm 31
Rotation and rotate, and crank arm and 31 can deliver torque to rocking arm 32, rocking arm 32 and crank arm 31 respectively positioned at adapter sleeve 20
Both sides.One end of connecting rod 50 is fixed on base 10, and the head 311 of rocking arm 32 is set on connecting rod 50, and makes the head of rocking arm 32
The mode that portion 311 can slide on connecting rod 50 is set, and connecting rod 50 is divided into two sections by the head 311 of rocking arm 32.Two stage clips point
It is not set on two sections of connecting rods 50, and thrust is produced to the head 311 of rocking arm 32 respectively.When cable because being influenceed by extraneous factor and
When shaking, cable will pass to because of wave force caused by rocking cranks arm 31, and cranking arm 31 generation slight oscillatories and swings this
Rocking arm 32 is passed to, so as to buffer this wave force by the change of two stage clip decrements.
It should explain：When tensioning wheel 40 provides certain tensioning for cable to remain static, the head of rocking arm 32
311 are also at inactive state, and now, it is 0 that what the head 311 of rocking arm 32 was subject to, which makes a concerted effort, and the component that should make a concerted effort is correct for two stage clips
Thrust and rocking arm 32 resistance in portion 311 crank arm 31 torsions and the twisting resistance in caused moment of torsion.The moment of torsion causes rocking arm 32
Head 311 always has the trend slided along connecting rod 50, in a preferred embodiment of the invention, cable is located at tensioning wheel 40
Lower section, two stage clips include the first stage clip 70 and the second stage clip 60, the elastic force for making the first stage clip 70 be provided in initial mounting state
The elastic force provided more than the second stage clip 60 in initial mounting state, the coefficient of elasticity of the first stage clip 70 can be such as set to be more than the second stage clip
60 coefficient of elasticity.In this way, the elastic force (or coefficient of elasticity) for the stage clip that resistance rocking arm 32 reverses is turned round always greater than rocking arm 32 is complied with
The elastic force (or coefficient of elasticity) of the stage clip turned, so that when cable increases suddenly because of oneself factor tensile force, rocking arm 32 is because of the
The larger total energy of coefficient of elasticity of one stage clip 70 resists this unexpected increase, similarly, when cable because oneself factor tensile force is unexpected
During reduction, rocking arm 32 can comply with this unexpected reduction because the coefficient of elasticity of the second stage clip 60 is smaller.Above-mentioned rocking arm 32 this
Kind of characteristic can effectively prevent that cable is damaged fracture because of unexpected external force.
For that can adjust the pretightning force of the first stage clip 70 and the second stage clip 60, one end of connecting rod 50 is fixed on base 10,
The other end is provided with adjusting nut 80, and the first stage clip 70 is located between adjusting nut 80 and the head 311 of rocking arm 32, the second stage clip
60 between base 10 and the head 311 of rocking arm 32.In this way, when needing to reduce influence of the external force to tensile force of cable,
Adjusting nut 80 is rotated, increases the decrement of the first stage clip 70 and the second stage clip 60, in this way, even if cable is by larger external force
When, the fluctuation of its tensile force also will not be excessive；When needing to reduce influence of the elongation of itself to tensile force of cable, rotate and adjust
Whole nut 80, reduce the decrement of the first stage clip 70 and the second stage clip 60, in this way, even if cable its length increases, first
The stage clip 60 of stage clip 70 and second can also comply with the increase of length of cable by telescopic adjustment.
As further preferred, connecting rod 50 is inclined relative to horizontal setting, and is fixed on fixed sloping platform 11, connecting rod 50
Inclination angle scope be 30 ° to 60 °.
Selected as one kind, rocking arm 32 and 31 junction of cranking arm are arranged with watt set 90, and clamp screw is provided with watt set 90
Nail 91, holding screw 91 is from the endoporus for stretching into watt set 90 outside so that rocking arm 32 and cranking arm 31 to be locked.
For the head 311 of rocking arm 32 can be enable to be slided along connecting rod 50, the head 311 of rocking arm 32 opens up an elongated hole 312,
Connecting rod 50 wears the elongated hole 312 so that rocking arm 32 is when swinging, and connecting rod 50 will not interfere with the head 311 of rocking arm 32.
Above example is only the exemplary embodiment of the present invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make respectively in the essence and protection domain of the present invention to the present invention
Kind modification or equivalent substitution, this modification or equivalent substitution also should be regarded as being within the scope of the present invention.
