Auxiliary hoisting bracket for replacing any piece of tension insulator of direct-current transmission line

The utility model discloses an auxiliary hoisting bracket for replacing any piece of a tension insulator of a direct-current transmission line, and aims to provide an auxiliary hoisting bracket capable of improving the replacement efficiency of the tension insulator of the direct-current transmission line. Wherein the two triangular supports are symmetrically located at the two ends of the cross beam pipe, the top ends of the triangular supports are fixedly connected with the cross beam pipe, the cross beam pipe is sleeved with the two sliding bases in a sliding mode, the sliding bases are located between the two triangular supports, the pulley assemblies are hinged to the lower portions of the sliding bases respectively, and the clamping mechanisms are fixedly arranged on the two sides ofthe lower ends of the triangular supports respectively. The clamping mechanism comprises a first clamping block fixedly connected with the lower end of the triangular support and provided with a first arc groove in the lower
