Abstract
The utility model relates to a clamp for testing the longitudinal tension of a flexible pipe. The clamp comprises a roll shaft, a cross beam, side plates and a rigid bar, wherein two ends of the cross beam are connected with the side plates, and the cross beam is connected with the roll shaft through the side plates; a slotted hole is formed in the roll shaft; and one end of a flexible pipe to be tested is connected into the slotted hole in a clamping mode through the rigid bar, and the rigid bar is used for fixing the flexible pipe to be tested onto the roll shaft. The flexible pipe sample to be tested is put in the slotted hole in the roll shaft, the flexible pipe is fixed on the roll shaft through the rigid bar, and therefore enough large clamping force is provided. The other end of the flexible pipe is clamped by a same clamp, so that the test for the longitudinal tension of the flexible pipe is realized. Meanwhile, as the contact area of the sample and the clamp is greatly increased, the pressure is reduced, and therefore the damaged chance of the sample is effectively reduced.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.
The anchor clamps of the utility model comprise roll shaft, crossbeam, side plate and rigid rod; The two ends of said crossbeam are connected with side plate; Said crossbeam is connected with roll shaft through side plate; Said roll shaft is provided with slotted eye, and said rigid rod is connected to an end of flexible pipe to be tested in the slotted eye, is used for flexible pipe to be tested is fixed on roll shaft.The utility model is put into the inner slotted eye of roll shaft with tested flexible pipe sample, through rigid rod flexible pipe is fixed on the roll shaft, thereby enough big holding force is provided, and the other end also carries out clamping with same anchor clamps, to realize the test of flexible pipe longitudinal pulling force.Simultaneously, because the contact area of sample and anchor clamps increases greatly, pressure reduces, thereby has reduced the impaired probability of sample effectively.
As illustrated in fig. 1 and 2, be a kind of embodiment of the utility model, the two ends of flexible pipe to be tested respectively are fixedly connected anchor clamps, bring in the test of carrying out longitudinal pulling force through two of clamps flexible pipe.The anchor clamps of this embodiment comprise roll shaft 1, crossbeam 8, side plate 4 and rigid rod 6, and the two ends of said crossbeam 8 are connected with side plate 4, and said crossbeam 8 is connected through the outstanding coupling shaft in side plate 4 and roll shaft 1 side, can realize being connected of roll shaft and crossbeam.Said roll shaft 1 is provided with slotted eye, and said rigid rod 6 is connected to an end of flexible pipe to be tested 3 in the slotted eye, is used for flexible pipe to be tested 3 is fixed on roll shaft 1.Be connected with pull head 9 on the crossbeam 8 of this example, said pull head 9 is connected with stress part, is used for to crossbeam 8 pulling force being provided, thereby external force is provided for the tensile test of flexible pipe.The maximum pull that bears that stress part provides is 50kN, and stress part can be the various suitable parts that external force is provided, for example puller system etc.In order to test for some thin fragile flexible pipe, preferably, flexible pipe to be tested is superimposed with ox-hide band 7.This embodiment is superimposed an ox-hide band and a sample with flexible pipe sample same widths, and the ox-hide band is close to the roll shaft surface, and flexible pipe and ox-hide band are superimposed and test pulling force.
The roll shaft 1 of the utility model can be various suitable rotating shafts, is used for flexible pipe to be tested is wrapped in roll shaft, is preferably knurling roller.The material of knurling roller can be 45# quenched and tempered steel, and external diameter can be 5～30mm.In order to improve the friction force of roll shaft, this roll shaft is provided with decorative pattern, and flexible pipe to be tested is wrapped on the roll shaft a few.Slotted eye on the roll shaft 1 also can be various suitable shapes, is used for clamping flexible pipe to be tested, is preferably wedge-shaped slot, because wedged hole is up big and down small, more helps the rigid rod clamping and lives flexible pipe to be tested 3.Rigid rod 6 also can be preferably the annular knurl rod for various metals or nonmetal barred body, through reverse tension sample, the annular knurl rod is pressed on sample on the wedge shape cell wall, can prevent the sample slippage effectively, guarantees that tensile sample carries out smoothly.The utility model is put into the inner wedge-shaped slot of knurling roller with tested flexible pipe sample, oppositely strains sample then, again with sample on the knurling roller a few, form self-locking, enough big holding force is provided.
