Pulling-out and detaching tool for elbow type cable end

Abstract

The invention discloses a pulling-out and detaching tool for an elbow type cable end. The pulling-out and detaching tool comprises a movable disc, a static disc, screw rods, rotary handles and the like. According to the principle of acting force and counter-acting force in physics, an object is fastened gradually based on circular rotation and friction of the inclined surface of the object so as to enable the elbow type cable end to be detached; a large amount of physical power can be saved, the working time consumption of operators in detaching the elbow type cable end can be effectively reduced so as to finish first-aid repair in a faster and better manner, and great economic benefit can be brought; the integral configuration of the static disc and the movable disc is suitable for being used in a ring main unit or a high-voltage junction box, so that the cable end is effectively protected, the damage to the cable end caused in manual pulling-out process can be avoided, and the external insulation of the cable end is protected.

Description

technical field [0001] The invention relates to the field of distribution network maintenance, in particular to an elbow-shaped cable head pull-out tool. Background technique [0002] According to statistics, in power distribution equipment such as ring network cabinets and high-resolution boxes used in distribution networks, most of the cable heads use pre-cast T-shaped cable joints, also known as elbow-shaped cable heads. The elbow cable head has a high safety factor in daily operation, which can guarantee the user's electricity consumption, but it is very difficult to disassemble for maintenance and emergency repairs. This is because the elbow cable head generally adopts a negative pressure cavity structure, and silicone grease is used for installation. Sealing, the silicone grease will dry out after a long time, which will cause pressure in the elbow cable head and make it inconvenient to disassemble. It is often pulled out by force, and the staff often damages it when r...

Problems solved by technology

The elbow cable head has a high safety factor in daily operation, which can guarantee the user's electricity consumption, but it is very difficult to disassemble for maintenance and emergency repairs. This is because the elbow cable head generally adopts a negative pressure cavity structure, and silicone grease is used for installation. Sealing, the silicone grease will dry out after a long time, which will cause pressure in the elbow cable head and make it inconvenient to disassemble. It is often pulled out by force, and the staff often damages it when removing the elbow cable head. Once the elbow cable head is damaged, it will be unusable, and the price of a set of cable accessories is often thousands of yuan

[0003] At present, there is no special removal tool for this kind of elbow cable head on the market, so it is a subject with strong practical value to develop a pull-out tool suitable for elbow cable head
