Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of example structure schematic diagram of the strength test device of cable insulating sheath of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, for the strength test device structural representation of the cable insulating sheath of the embodiment of the present invention, comprise motor 1, tautness meter 2, web member 3, fixed part 4, clamp system 5, base 6 and baffle plate 7, motor 1, fixed part 4 and baffle plate 7 are arranged on base 1.Motor 1 comprises rotating shaft 11, clamp system 5 comprises the first clamping element 51 and the second clamping element 52 for clamping insulating sheath, tautness meter 2 one end is connected with rotating shaft 11 by web member 3, and the other end is connected with the first clamping element 51, and the second clamping element 52 is fixed on fixed part 4.Open motor 1 power supply, rotating shaft 11 is according to certain speed uniform rotation, pull tautness meter 2 and the first clamping element 51 to move to rotating shaft 11 according to the speed of 25.5 ± 3.5mm per minute by web member 3, tautness meter 2 can demonstrate the maximum pull that insulating sheath can bear.Certainly, in other embodiments, according to the insulating sheath of varying strength or xsect size, the running speed of motor 1 can be set, thus change the point-to-point speed of tautness meter 2 and the first clamping element 51.
Tautness meter 2 can select digital display type tautness meter, pointer tautness meter or figure to show tautness meter, and web member 3 comprises rope, and rope one end is connected with the test lead of tautness meter 2, and the other end is set around in rotating shaft 11.In the present embodiment, wire rope selected by rope, wire rope plays traction, tension and the effect of bearing load, it has higher tensile strength and fatigue resistance, softness better and not easily fractures suddenly, can improve the security of test process as the connecting media carrying out strength test to insulating sheath in the present embodiment.
Fixed part 4 comprises fixed head, and fixed head is fixed on base 6, and the second clamping element 52 is fixed on fixed head.Fixed head is be arranged at the vertical plate on base 6, because fixed head need bear the pulling force from motor 1, therefore fixed head should select suitable mode to be fixedly connected with base 6 with the second clamping element 52 respectively, in addition in order to ensure that fixed head is not fractureed easily in test process, the metal material of selection intensity more very much not frangibility can make sheet metal, and weld with the second clamping element 52 and base 6 respectively, ensure its stable connection.
Baffle plate 7 is arranged between tautness meter 2 and motor 1, baffle plate 7 is provided with the first through hole, and rope is connected with rotating shaft 11 through the first through hole.Baffle plate 7 is for preventing tautness meter 2 to be pulled to rotating shaft 11 place by rope and damaged after being wound in rotating shaft 11.The size of the first through hole slightly larger than the xsect size of rope, preferably should not contact with each other between the inwall of rope and the first through hole and baffle plate 7, causes wearing and tearing to avoid friction to rope.Buffer part (not shown) is also provided with between tautness meter 2 and baffle plate 7.In the present embodiment, buffer part comprises cushion pad, and cushion pad is arranged on fixed head, and cushion pad offers the second through hole, the second through hole and the first through hole through.Cushion pad generally adopts rubber or natural rubber material to make, by mould one-time cast-forming or impact briquetting, by expansion bolt or be welded and fixed when installing with baffle plate 7.The effect of cushion pad is that protection tautness meter 2 can not be rubbed to during baffle plate place by pulling, or plays the effect of buffering when motor 1 running speed is too fast, reduces the probability that tautness meter 2 is damaged.
In the present embodiment, the first clamping element 51 comprises first clamp, and the second clamping element 52 comprises second clamp, and first clamp is connected with one end of tautness meter 2, and second clamp 52 is fixed on fixed head.First clamp and second clamp comprise the clamping face for clamping insulating sheath respectively, insulating sheath is held more fastening to make first clamp and second clamp, clamping face is provided with broached-tooth design, the friction force between the clamping face of clip and insulating sheath can be strengthened by broached-tooth design, thus strengthen the snap-in force of clip, when avoiding that in test process, motor pulls first clamp, insulating sheath departs from first clamp or second clamp.Certainly, first clamp and second clamp
Above disclosedly be only present pre-ferred embodiments, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
