Self-locking composite conducting wire hoisting hook

Abstract

The invention discloses a self-locking composite conducting wire hoisting hook. The self-locking composite conducting wire hoisting hook comprises a hanging ring and conducting wire hooks, wherein the hanging ring is arranged on a crossbeam; the conducting wire hooks comprise an upper conducting wire hook and a lower conducting wire hook, which are connected with each other to form a whole body through a connecting rod and the crossbeam, and are respectively connected with the connecting rod to form a U-shaped storage structure for storing a conducting wire; the center of the hanging ring stays on a same straight line with the centers of the U-shaped storage structures of the upper and lower conducting wire hooks; and each U-shaped storage structure is provided with a self-locking mechanism for preventing the conducting wire from dropping off. The self-locking composite conducting wire hoisting hook can ensure that gravity core of the conducting wire does not deviate in hoisting; and through the self-locking design, the conducting wire is prevented from dropping from the hook in hoisting, and can be locked firmly and unlocked automatically, so that the working time does not increase, and the hoisting safety and reliability can be improved.

Description

technical field [0001] The invention relates to a self-locking double wire lifting hook. Background technique [0002] At present, the existing multi-conductor lifting tools for transmission lines are widely used, but the known lifting tools have shortcomings to varying degrees, for example, the lifting ring and the upper and lower conductor hooks are not on the same straight line, causing the hook The center of gravity is shifted, and the lower wire is easy to fall off. [0003] With the rapid development of power grid construction, 66kV-330kV transmission lines are designed with multiple conductors on a large scale. During maintenance, lifting of multiple conductors will often be encountered. In response to this demand, the special hook for lifting self-locking double conductors suitable for 66kV-330kV transmission lines has very realistic research and development value. [0004] 66kV-330kV transmission line self-locking double conductor lifting special hook is not only ...
