Description

Determine power continuous self-locking type minor diameter wire tightener

Technical field

The utility model relates to a kind of trapezoidal inclined plane Self-locking angle that adopts and locks the clamping device of mutual alignment, particularly relate to a kind of can utilize before coming and going repeatedly is carried out in the clamping of folder steel wire rope by lock claw in the process of motion, to send motion determine power continuous self-locking type minor diameter wire tightener.

Background technology

Now, the steel wire tensioner used in various occasion can be divided into two kinds, and a kind of is to the tension of heavy caliber steel wire rope machinery, adopts that circular shaft is rotary-type to be rolled youngster gradually by steel wire rope play tensioning function, as hoist engine etc. by rotating.Roll tightly although this machinery can realize continuous print, obviously very impracticable to the working environment of minor diameter steel wire rope or the frequent movement of needs, and unload at the follow-up steel wire that can be difficult to rolling in process of cutting off.Another kind small-sized pulls stem equipment, good effect can be had to the tension of minor diameter steel wire, also can arbitrarily movement, but lose the convenience of tension continuously, because the pawl pressing from both sides steel wire cannot self-locking, after having to pass through the action repeated in a few road after steel wire rope being drawn a bit of distance so each, clamping could strain a bit of distance more again.This will make work efficiency drop a lot of when practice, even if taut wire also cannot recognize that the tightening force of end steel wire is how many, this just can only rely on the experience of operating personnel to judge for there being the occasion of tightening force requirement, the problem easily causing tightening force too small or excessive; If tightening force is too small, easily skidded off by tight object, do not play the effect of tighten at all; If tightening force is excessive, in the process of transporting object, special change is when turning, and the impulsive force of object can strengthen the tightening force of steel wire rope, goes beyond the limit of and steel wire rope is pulled off cause very large loss.
