When carrying out logging cable breaking test, it is necessary to which a pair of cable cleats are used cooperatively, it is respectively used to clamp cable
Both ends.
Referring to Fig. 9-Figure 13, the assembling of the fixture is as follows using process：
1. an outer cone 31 is fixed on bench vice, cable is penetrated suitable position in the taper hole 7 of outer cone 31, uniformly separated
The cover wire of cable, then the tapering point of middle cone 32 is inserted between cable outer layer steel wire and steel wire of internal layer, now, outside cable
Layer steel wire is between 32 outer walls of middle cone and the taper hole inwall of outer cone 31, and cable steel wire of internal layer is in the taper hole 7 of middle cone 32.
2. outer cone fastening shell 34 is threadedly coupled with outer cone 31, as outer cone fastens the precession of shell 34, outer cone fastening shell 34
Interior stepped hole 34-1 step surface 34-3 is compressed downwards in the taper hole 7 of cone 31 outside with 32 end contacts of middle cone and by middle cone 32,
So as to which cable outer layer steel wire is pressed between 32 tapering point outer walls of middle cone and the taper hole inwall of outer cone 31.
3. outer cone fastening shell 34 is dismantled, after then cable steel wire of internal layer is uniformly separated, by the tapering point of inner cone 33
It is inserted between cable steel wire of internal layer and cable core, now, cable steel wire of internal layer is located at the tapering point outer wall of inner cone 33 and the middle cone of cone 32
Between the inwall of hole, cable core is located in the through hole of inner cone 33.
4. outer cone fastening shell 34 is threadedly coupled with outer cone 31, then inner cone fastening shell 35 is screwed in the platform of outer cone fastening shell 34
In the 34-1 of rank hole, as inner cone fastens the precession of shell 35, the limiting stand terrace 35-1 of inner cone fastening shell 35 and the limit on inner cone 33
Position ring 33-1, which coordinates, to be pressed on inner cone 33 in the taper hole 7 of middle cone 32, so as to which cable steel wire of internal layer is pressed on into the taper of inner cone 33
Between holding 32 taper hole inwalls of outer wall and middle cone, so as to which whole clamp assemblies 3 are completed.
5. whole clamp assemblies 3 are put into the shell that upper and lower outer casing framework 1,2 forms, and with screw by upper and lower shell
Skeleton 1,2 is fixed together.Then, it is clamped in using the step 6 of outer shell outer wall on tensile testing machine, is tried
Test.
Referring to Figure 14-Figure 16, the unloading process of the fixture is as follows：
1. after the completion of experiment, its entirety is removed from testing machine, then taken out clamp assemblies 3.
2. an outer cone 31 is fixed on bench vice, outer cone fastening shell 34 is loosened with spanner, screws out 5mm upwards, so that
Obtain inner cone fastening shell 35 and outer cone fastening shell 34 moves up 5mm, the limiting stand terrace 35-1 and inner cone 33 of inner cone fastening shell 35 together
On spacing ring 33-1 separation 5mm distances, stepped hole 34-1 step surface 34-3 in middle cone 32 top end faces and outer cone fastening shell 34
Between separate 5mm.
3. pull-off nut 8 is threadedly coupled with inner cone 33, due to the hand of spiral between pull-off nut 8 and inner cone 33 with it is interior
Between cone fastening shell 35 and outer cone fastening shell 34 and outer cone is fastened between shell 34 and outer cone 31 unanimously, therefore, in precession pull-off spiral shell
Inner cone 33 can outwards be extracted while mother 8, inner cone 33 is departed from 32 taper holes of middle cone and unclamp, now, it is possible to easily
Disassemble inner cone fastening shell 35 and inner cone 33.
4. part 9 similarly, will be bored in pull-off to screw into middle cone 32, due to boring the connection between part 9 and middle cone 32 in pull-off
The connection screw thread between part 9 and outer cone fastening shell 34 is bored in screw thread and pull-off, both hands of spiral are consistent, therefore can be in precession
Middle cone 32 is outwards extracted while part 9 are bored in pull-off, unclamped so that middle cone 32 departs from the taper hole of outer cone 31, so as to easily tear open
Middle cone 32 and outer cone fastening shell 34 is laid down, completes whole dismounting process.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
