Technical field
The utility model relates to a kind of hoisting sling.
Background technology
The renewal of electrical equipment maintenance at present needs some parts of lifting, usually adopt crane, because the crane volume is bigger, can not guarantee during operation and on every side charging equipment enough safety distances are arranged, so necessarily require adjacent spaces to have a power failure or the bus power failure, the electrical equipment around the arm of crane bumps in rotary course easily simultaneously by mistake.In order to guarantee when carrying out the electric power maintenance, to guarantee the normal operation of adjacent spaces equipment, when maintenance, adopt wooden suspension bracket, this wooden suspension bracket fixedly colligation adopts rope, and is not only time-consuming, and has potential safety hazard, and the maintainer uses also inconvenient.
The utility model content
Technical problem to be solved in the utility model is: a kind of hoisting sling is provided, and this hoisting sling can not only guarantee the normal operation of adjacent spaces electrical equipment when electric power keeps in repair, and is simultaneously easy to use.
Solve this technical problem, the technical solution of the utility model is: a kind of hoisting sling, it comprises fixed support, suspension rod, suspension arm, hoisting mechanism, hand rotation mechanism, the bottom of suspension rod is connected with fixed support, one end of suspension arm is fixed in the top of suspension rod, the other end has hoisting mechanism, and hand rotation mechanism is positioned at the bottom of suspension rod, and the rotation manual rotating mechanism can make suspension arm rotate around the suspension rod line of centers.
Described suspension rod passes through flange connection by forming more than two joints between every joint.
Described hand rotation mechanism comprise connecting arm, manually dish, manually coil rotating shaft, miniature gears, big gear wheel, connecting arm is captiveed joint with suspension rod, the line of centers of big gear wheel and the central lines of suspension rod, manually coil, manually coil rotating shaft and miniature gears and form one, manually dish is positioned at the stage casing of manual dish rotating shaft, miniature gears is positioned at manual dish rotating shaft top, miniature gears and big gear wheel engagement.
Described fixed support is made up of the support arm of two levels, the chuck at each support arm two ends, and the lower end of suspension rod and support arm sliding block joint can move back and forth with respect to support arm, and the top of suspension rod has the detouchable clamping limb.
Described suspension rod, manual appearance of coiling, manually coiling rotating shaft are enclosed with insulating barrier.
A kind of hoisting sling of the utility model adopts such structure, makes the maintainer be operated in the very little safe range, and is easy to assembly, safe and reliable, not influenced by adjacent charging equipment, hoisting process need not neighbouring device be accompanied and is stopped, and ensures the safe and reliable operation of electrical network; Reduced maintainer's work capacity, can in various complicated operations environment and working condition, use.
