[0022] Example 1: Transmission cables used to suspend power facilities on water

[0023] The tension self-locking transmission cable hanger used in the transmission line of the present invention is made of steel pipes or steel rods. When the power transmission cable is suspended on the steel wire rope between the electric tower and the water facilities, the load-bearing steel wire rope fixedly connected to the shore electric tower passes through the upper hook 1 at one end of the main body A of the hook, and passes through the upper support top 3 of the eccentric bracket B Hold it up, and then pass through the upper hook 1 at the other end of the main body A of the hook, and then lead the wire rope to be fixed on the water facility. Due to the static friction between the wire rope and the hook, it remains relatively stationary with the wire rope and does not move; similarly, the power transmission The cable D passes through the lower hook 2 corresponding to the main body A of ...

Abstract

The invention discloses a tension self-locking type power transmission cable suspension tool for a power transmission line, and belongs to the field of power transmission line tools and machine tools. The tension self-locking type power transmission cable suspension tool consists of a hook body and an eccentric bracket, wherein an upper hook and a lower hook are connected with each of two ends of the hook body separately; the eccentric bracket is provided with an upper supporting top and a lower supporting top separately; the eccentric bracket is connected in the middle of the hook body; the upper hooks at two ends of the hook body are suspended on a steel wire rope, which is fixedly connected in a tensioning manner, to enable the steel wire rope to be correspondingly supported by the upper supporting top of the eccentric bracket; and the power transmission cable is correspondingly suspended on the lower hooks at two ends of the hook body and supported by the corresponding lower supporting top of the eccentric bracket. According to the tension self-locking type power transmission cable suspension tool, a relative stationary state between the hook and the steel wire rope, and between the hook and the power transmission cable without displacement is realized through static friction force, thereby ensuring the reliability and the safety in use of the hook for the power transmission cable.

Description

technical field [0001] The invention relates to a tension self-locking type power transmission cable hanger used for power transmission lines, belonging to the field of power transmission line work tools. Background technique [0002] The power supply of buildings and facilities on land usually uses poles to support aerial transmission lines. The interval between poles can be determined according to the site conditions and the tensile strength requirements of the cables themselves. Therefore, the power transmission lines on land generally rely on the cables themselves. To withstand the internal tension generated by its own weight. After the water facilities (such as barges, water plants, water restaurants, etc.) are positioned on the water, their power supply generally adopts the power transmission method of land cable power supply, and the transmission cable is pulled to the water facilities through the transmission tower on the shore. The greater the distance between the ...
