Description
Technical field
The present invention relates to a kind of high-tension cable wiring annex, the automatic back-twist device of especially a kind of high-pressure cross-linking cable snap joint.
Background technology
Usually snap joint is used as realizing quantity-produced drafting tool in the manufacture process of high-pressure cross-linking cable.Existing tow attachment generally adopts double end aluminium hydraulic pressed connecting pipe or aluminium hydraulic pressed connecting pipe and fastener to combine, but this connected mode is Hard link, if there is certain torsion in cable in connection procedure, and this torsion is not once adjust and the words of releasing by position, in use snapping bolt will be unscrewed or twist into two parts, distorting stress too concentrates the junction bird caging of passing siding cable, there is larger potential safety hazard.In addition, even if this torsional deformation is in the not serious situation of degree, under the summation of certain hour, the useful life of cable can also be had influence on.
Summary of the invention
For the deficiencies in the prior art, object of the present invention is intended to provide a kind of high-pressure cross-linking cable snap joint automatic back-twist device, in order to remove the harmful effect of torsional deformation to cable self and cable union piece, releases the angular displacement in torsional deformation.
For achieving the above object, the present invention adopts following technical scheme:
The automatic back-twist device of high-pressure cross-linking cable snap joint, comprises the first cable and the second cable, and this two cable all has free end close to each other, and the automatic back-twist device of this high-pressure cross-linking cable snap joint also comprises:
Shank, this shank one end has free end grafting the first spliced eye wherein for the first cable;
One end of sheath body has free end grafting second spliced eye wherein of the second cable, and the other end of sheath body offers cavity, and the other end of shank is plugged in cavity inside actively;
Be embedded in the thrust bearing in cavity, it comprises the first thrust washer and the second thrust washer, this first thrust washer is fixed in cavity, the other end of this second thrust washer and shank is affixed, this second thrust washer, between two first thrust washers, is provided with ball between this first thrust washer and second thrust washer.
Preferably, this second thrust washer is socketed on the shank other end, this shank has the limited step for supporting the second thrust washer one end face, the shank end being positioned at the other end of the second thrust washer is bolted with a spacing collar, this spacing collar side opening is provided with the first jack, and this shank side opening is provided with second jack corresponding with the first jack; The automatic back-twist device of this high-pressure cross-linking cable snap joint also comprises spline latch, and this latch is plugged in the first jack and the second jack successively, and limited step and spacing collar form the clamping part of clamping second thrust washer.
Preferably, sheath body comprises upper half-shell and housing lower half, welds between upper half-shell with housing lower half.
Beneficial effect of the present invention is:
Compared to prior art, the present invention is provided with the bearing of a pivot center and two cable deads in line.The free end of the first cable is fixed in the second thrust washer of thrust bearing by shank, the free end sheath body that second cable passes through is fixed in the first thrust washer, be slidably matched between first thrust washer and the second thrust washer, between existence two cable exist reverse the trend or angular displacement difference time, thrust bearing play the angular displacement released in torsional deformation, remove torsional deformation to cable self and the dysgenic effect of cable union piece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial view at Figure 1A place.
Wherein, the 1, first cable; 2, the second cable; 3, shank; 4, sheath body; 5, limited step; 6, the second thrust washer; 7, spacing collar; 8, the first thrust washer; 9, spline latch.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
As shown in Figure 1 and Figure 2, the automatic back-twist device of high-pressure cross-linking cable snap joint, comprises the first cable 1 second cable 2, shank 3, sheath body 4, thrust bearing.Two cables all have free end close to each other.This shank 3 one end has free end grafting the first spliced eye wherein for the first cable 1.One end of sheath body has free end grafting the second spliced eye wherein for the second cable 2, and the other end of sheath body 4 offers cavity, and the other end of shank 3 is plugged in cavity inside actively.This thrust bearing is embedded in cavity inside, thrust bearing comprises the first thrust washer 8 and the second thrust washer 6, this first thrust washer 8 is fixed in cavity, this second thrust washer 6 is affixed with the other end of shank 3, this second thrust washer 6, between two first thrust washers 8, is provided with ball between this two first thrust washer 8 and second thrust washer 6.This ball quantity is multiple, and this ball is provided for the first thrust washer 8 and trackslips with the second thrust washer 6 and coordinate.So; when there is the trend of angular displacement difference or twist motion in both the first cable 1 and the second cable 2; second thrust washer 6 of bearing and the first thrust washer 8 immediately will make pivotable adjustment; relieve twist motion trend between two cables and angular displacement poor; protect two cables and connect other annexes of two cables, thus decreasing the useful life that fault occurs and improve each part.
As the preferred scheme of one, this second thrust washer 6 is socketed on shank 3 other end, this shank 3 has the limited step for supporting the second thrust washer 6 one end face, the shank end being positioned at the other end of the second thrust washer is bolted with a spacing collar 7, this spacing collar 7 side opening is provided with the first jack, and this shank 3 side opening is provided with second jack corresponding with the first jack; The automatic back-twist device of this high-pressure cross-linking cable snap joint also comprises spline latch 9, and this latch is radially plugged in the first jack and the second jack successively, and therefore, when thrust bearing rotates, spacing collar 7 would not get loose easily.This limited step and spacing collar 7 form the clamping part of clamping second thrust washer 6.
As the preferred scheme of one, sheath body 4 comprises upper half-shell and housing lower half, is welded to connect between upper half-shell and housing lower half.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range of the claims in the present invention.
