Abstract

The invention relates to a closed block for cable lay-out on a tower. The closed block is characterized in that a vertical pulley I, a vertical pulley II and a horizontal pulley are arranged in a fixed frame; one end of the vertical pulley I and one end of the vertical pulley II are respectively connected with the two ends of the horizontal pulley; a sealing door is arranged between the other end of the vertical pulley I and the other end of the vertical pulley II; and a connecting mechanism is arranged at one side of the fixed frame. The closed block is light and flexible when used for cable lay-out on a tower. Through rotation of the three pulleys with the same radian, the problem of cable scratch is eliminated, and the quality of cable construction is improved. The vertical pulley II is a movable pulley, which can prevent a cable from popping out from the block. Moreover, the block is installed on a tower by a fixed belt, and installation is convenient and flexible.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission, and in particular relates to a closed pulley for tower and cable deployment used for operation on power transmission lines. Background technique [0002] In the process of power system operation and maintenance, operators often need to replace cables online, and pulleys need to be hung when laying out cables on poles and towers. In the past, ordinary pulleys used for cable replacement may easily cause the cable protective layer to be scratched by the pulley wall. Contents of the invention [0003] Aiming at the problems in the above-mentioned prior art, the present invention provides a closed block for tower cable deployment, which solves the problem that the block in the prior art easily causes the cable protective layer to be scratched. [0004] Technical scheme of the present invention is as follows; [0005] The fixed frame is provided with vertical pulley I, vertical ...
