Abstract

The invention discloses a pulley mechanism used in an electrical installation process. The pulley mechanism comprises two pulley yokes on which pulleys are mounted; each pulley yoke is connected to a bearing rod; the two bearing rods are connected through a connecting rod; the pulley mechanism is characterized by further comprising a brake device which comprises a brake bracket plate fixed to the two bearing rods or two pulley yoke brackets; a threaded through hole is formed in the brake bracket plate; a screw rod is arranged in the threaded through hole; a friction brake body is connected to one end of the screw rod, and a handle is connected to the other end of the screw rod; the two pulleys are suspended above a power line; the friction brake body is positioned in a gap between the power line and the brake bracket plate. The pulley mechanism is simple in structure and low in cost, and can realize brake at a fixed point; the pulley mechanism can be fixed to one particular point due to up and down extrusion; compared with a traditional hook design, the pulley mechanism provided by the invention is convenient to operate, can realize effective positioning, and avoids a sliding risk.

Description

technical field [0001] The present invention relates to an electrical installation tool, in particular to a mechanism based on pulleys used in electrical installations. Background technique [0002] The power transmission and distribution line is the main artery of power supply. The reliability of its power supply is directly related to the production of enterprises and the daily life of residents. The operation, maintenance quality and repair level of power transmission and distribution lines are closely related to people's lives. Line inspection and maintenance is particularly important. [0003] When overhauling and maintaining the transmission and distribution lines, if a fault is found, the operator generally hangs on the transmission and distribution line through a hanging component to perform line maintenance. The existing hanging assembly includes a hook hanging on the power transmission and distribution line, a sling is connected to the hook, and the other end of t...
