Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, develop simultaneously embodiment referring to the drawings, further describes this utility model.
As shown in Figure 1, 2, 3, a kind of stretching accessory of direct clamped wire rope, including jaw seat 1, jaw clamp 4, jaw pressing plate 2 and liner plate 3, trapezoidal grasping part it is provided with in jaw seat 1, jaw clamp 4 is symmetrically installed in grasping part, jaw clamp 4 is linked together by the sidewall of liner plate 3 with grasping part, and jaw clamp 4 can move forward and backward along liner plate 3；Jaw pressing plate 2 is positioned at the upper end of jaw clamp 4, and limiting jaw clamp 4 can not move up.The inner side of jaw clamp 4 is provided with jaw sheet 5, and steel wire rope is sandwiched between two jaw sheets 5.
As shown in Figure 4, the clamping face of jaw sheet 5 clamped wire rope is two crossing waveform planes, the i.e. cross section of jaw sheet is the V-arrangement tilted, the form friction pattern 7 of a plurality of increase jaw sheet and friction force of steel rope it is carved with on clamping face, described form friction pattern 7 is 60 ° of staggered twills, and the protruding end of the waveform clamping face of jaw sheet 5 is provided with the chamfering that gradient is less.The clamping face of jaw sheet 5 is two crossing waveform planes, form friction pattern 7 is set in plane, the contact area of clamping face and steel wire rope can be increased, reduce the pressure that chucking power produces on steel wire rope surface, and increase the frictional force between steel wire rope, prevent steel wire rope sliding.
