The invention discloses a pulley for power transmission line construction, and relates to the technical field of cable laying auxiliary equipment, and the pulley comprises a base frame and at least one pulley part; a gantry-type hanging bracket is further arranged on the base frame, a cross rod part is arranged in the middle of the gantry-type hanging bracket, the device further comprises a downward pressing pulley assembly, a driving part and at least one set of rotary clamping and fixing parts, the end of the downward pressing pulley assembly is located on the upper side of the pulley part, and the downward pressing pulley assembly is used for pressing a cable passing through the pulley part downwards from the upper side; the driving part is used for driving the rotary clamping part to rotate around the connecting position of the rotary clamping part and the transverse rod part, and the end, away from the transverse rod part, of the rotary clamping part can make contact with and clamp a cable passing through the lower side of the rotary clamping part. The cable tensioning device is simple in structure, a cable can be conveniently arranged in the annular groove of the pulley part and is not prone to slipping off during cable laying construction, the cable can be clamped from the two sides during cable tensioning operation, friction between the cable and surrounding objects due to sag when the cable loads a heavy object is avoided, and practicability is high.
本发明公开了一种输电线路施工用滑车,涉及线缆铺设辅助设备技术领域,该滑车包括底座框架和至少一个滑轮部;底座框架上还设置有龙门型吊架且龙门型吊架中部设置有横杆部,还包括下压滑轮组件、驱动部件和至少一组旋转夹固部件,下压滑轮组件的端部位于滑轮部的上侧,下压滑轮组件用于从上侧下压经过滑轮部的线缆;所述驱动部件用于驱动旋转夹固部件绕与横杆部的连接处转动,所述旋转夹固部件远离横杆部的端部能够接触并夹紧经过其下侧的线缆。本发明结构简单,便于线缆铺设施工时线缆置于滑轮部的环槽内且不易滑脱,紧线作业时,可从两侧夹紧线缆,避免线缆负载重物时,线缆弧垂而与周围物件发生摩擦,实用性较强。
