Abstract
The utility model provides a carbon fiber composite core rod pull force test clamp capable of being detached and repeatedly used. The carbon fiber composite core rod pull force test clamp is composed of a conical sleeve 1, a wedged inner cone 2, a rotating sleeve 3, a nut 4 and a connecting sleeve 5. The wedged inner cone 2 is sleeved in the conical sleeve 1 and the rotating sleeve 3 is connected with the conical sleeve 1 and the wedged inner cone 2; the rotating sleeve 3 is screwed on so as to enforce the wedged inner cone 2 to move forward to be tightly combined with the conical sleeve 1; meanwhile, a core rod is clamped and the rotating sleeve 3 is detached to connect the connecting sleeve 5 and the conical sleeve 1 to carry out pull force test; and after the test is finished, the clamp can be detached to be simply wiped and then can be repeatedly used. The carbon fiber composite core rod pull force test clamp capable of being detached and repeatedly used can be used for solving the waste problem that the clamp only can be used for one time when a core rod pull force test is carried out, so that the novel core rod pull force test clamp capable of being detached and repeatedly used is provided for the power line and cable industry.
Description
Technical field:
The utility model relates to mechanical manufacturing field, exactly belongs to electric wire manufacturing carbon fiber composite core rod tensile test and uses the grip device field.
Background technology:
Occurred both at home and abroad in recent years with carbon fibre composite as strengthening plug, skin holds the compound wire of annealed aluminum wire as electric power transfer unit.This composite conductor is to replace steel core with carbon fiber reinforced epoxy resin-based composite, has advantages such as linear expansion coefficient is little, in light weight, current-carrying capacity is big, line loss is low, has obtained the extensive approval of domestic power transmission and transformation system.At present, domestic existing 30 tame enterprises are manufacturing carbon fiber composite core rod, are exactly that plug must be done the pulling force detection but there are distinct issues in the manufacture process of plug.Because the singularity of carbon fiber composite core rod, detect at pulling force and can not adopt conventional plate jig to carry out clamping in the test, present domestic mechanism for testing adopts Wedge gripping, but such anchor clamps exist price high, can only disposable shortcoming.For the plug producer that reduces cost can only reduce the quantity of test, reduced control so to a certain extent to the plug quality.
Summary of the invention:
The object of the invention just provides a kind of can detachably the repeated use and low-cost carbon fiber composite core rod tension grip.The utility model is formed (see figure 1) by tapered sleeve, wedge shape inner cone, rotary sleeve, nut, adapter sleeve etc., and the wedge shape inner cone is inserted in tapered sleeve, and rotary sleeve connects tapered sleeve and wedge shape inner cone; Through tightening the reach of rotary sleeve compressing wedge shape inner cone; The slit diminishes, and inner cone and tapered sleeve are combined closely, and the wedge shape inner cone clamps plug; Dismounting is rotary sleeve down, with adapter sleeve with carry out tensile test after tapered sleeve is connected.
After test finishes; Take off the anchor clamps after the test from puller system; Tapered sleeve is fixed on bench vice through draw-in groove or the appropriate location is set level, screws off adapter sleeve from tapered sleeve, can expose the wedge shape inner cone this moment; Rotary sleeve is screwed in the end thread of tapered sleeve and tightens, and nut screws in the end thread of wedge shape inner cone and fixedly prevents to rotate simultaneously with rotary sleeve.Unload rotary sleeve with torque spanner,, when unloading rotary sleeve, just force the wedge shape inner cone move, so just the wedge shape inner cone is extracted from tapered sleeve with nut because wedge shape inner cone and nut are integrally formed, promptly reusable through these anchor clamps after the simple wiping.
The utility model is reused anchor clamps through the combination again of assembly, and having solved when carrying out the plug tensile test can only expendable waste problem, for wires and cables industry provides a kind of novel detachable reusable plug anchor clamps.
