High-falling-prevention maintenance support for top maintenance of large transformer

Abstract

The invention discloses a high-falling-prevention maintenance support for top maintenance of a large transformer. The maintenance support comprises: a first support, wherein the first support is fixedly connected with a vertical rod, and the vertical rod is provided with a hanging part; a second support comprising a first telescopic part and a second telescopic part, wherein the first telescopic part can stretch out and draw back in the left-right direction, the first support is detachably installed on the first telescopic part, the second telescopic part is arranged at the end, away from the first support, of the first telescopic part, and the second telescopic part can stretch out and draw back in the front-back direction; a winch detachably installed on the second support, wherein a steel wire rope is arranged on the winch; and a fixed pulley detachably installed on the second support, wherein the steel wire rope is suitable for being connected to the fixed pulley in a wound mode. When the maintenance support is used, the maintenance support needs to be placed on the top of a transformer box body firstly, then the steel wire rope is tensioned to be connected with the transformer box body so as to firmly fix the whole maintenance support, and therefore when a transformer is maintained, a maintainer can conveniently bind and hang a safety belt or a safety rope on the hanging part of the vertical rod.

Description

technical field [0001] The invention relates to the technical field of transformer maintenance auxiliary equipment, in particular to a large-scale transformer top maintenance anti-fall maintenance bracket. Background technique [0002] Overhaul and maintenance of large transformers happen every year. Every spring and autumn inspection of the State Grid Corporation of China will test the parameters of the transformer. The maintenance personnel climbed to the top of the transformer and the height of the fall is more than 2 meters. According to the requirements of safety regulations, measures to prevent high falls should be taken. The simplest is seat belt, safety rope. Since more than 90% of large-scale transformers do not require custom-made anti-fall facilities in the production agreement, operators have nowhere to use safety belts and safety ropes during maintenance and testing. Generally, two measures are taken to use the safety belt (safety rope). One is to remove the b...

Problems solved by technology

Since more than 90% of large-scale transformers do not require custom-made anti-falling facilities in the production agreement, operators have nowhere to use safety belts and safety ropes during maintenance and testing

Generally, two measures are taken to use the safety belt (safety rope). One is to remove the bolts of several fuel tanks and oil conservator (oil conservator) to install the anti-falling device to solve the correct use of the safety belt (safety rope). Fuel tank, oil pillow oil leakage

The second is to save trouble. In violation of regulations, the safety belt (safety rope) is tied to the high-voltage bushing of the transformer. In this case, a high-voltage fall accident is likely to occur, which will cause the high-voltage bushing to break and damage the equipment.
