For clamper can freely slide up and down along steel strand wire, on right clamping body, be equiped with directive wheel.
Reliable in order to make steel strand wire and upper and lower support attachment security, be fixed with wedge clamp and socket respectively at the two ends of steel strand wire.Wedge clamp is connected with cramp bar on being fixed on upper bracket by eyelet bolt, and socket is connected with yoke by bolt, and the lower end of yoke is fixed on the lower carriage.
Impulsive force when falling in order to absorb is equiped with buffer spring on upper bracket, buffer spring is sleeved on the cramp bar, and both ends of the spring is replaced at upper bracket respectively and is fixed on the spring pad of cramp bar upper end.
Be not subjected to the influence of steel strand wire when pedaling the tower operation for the ease of the workman, the utility model is arranged on the steel streakline on the right side of iron tower main material.
During use, operator's safety belt is connected with the chain of rings of clamper by the chain rope, and under normal condition, clamper is positioned at the below of operator's health all the time, is subjected to the effect of clamper deadweight, and the eccentric cam of 2 depression bars is in release condition.Clamper can be along the freely upper and lower slip of steel strand wire by damping wheel and guide wheel, promptly operates and falls in case accident occurs, just drives 2 depression bars, makes its eccentric cam extruding steel strand wire distortion, makes the clamper braking, thereby guarantees operator's safety.
The utility model is simple in structure, clamper loading and unloading easily, easy to use, can guarantee that the operator can not fall because of the high-altitude to cause injures and deaths, can be applicable in power supply enterprise.
