Abstract

The invention discloses a safety belt hanging device for maintenance of a main transformer. The safety belt hanging device comprises an accommodating cavity, a hydraulic jack, a sleeve and a insertionrod; the accommodating cavity comprises an upper wall, a lower wall, a front wall, a rear wall, a left side wall and a right side wall; the front wall, the rear wall, the left side wall and the rightside wall are connected to the peripheries of the upper wall and the lower wall in an encircling mode; a clamping seam is formed in the front wall, the left side wall and the right side wall of the accommodating cavity from the front wall to the rear wall, wherein the left side wall and the right side wall are connected with the front wall; a demising groove is formed in the front wall of the accommodating cavity; the hydraulic jack is arranged on the lower wall in the accommodating cavity; the sleeve is fixedly connected to the accommodating cavity; one end of the insertion rod can be inserted into the sleeve to be coaxially and detachably connected with the sleeve, and a connection portion connected with a safety belt is arranged at the other end of the insertion rod. The safety belt hanging device has the advantages that the hanging device can be fixed to the edge of the main transformer under large pressure, and accordingly, personal safety of maintainers during maintenance on upper part of the main transformer is guaranteed greatly; the safety belt hanging device is small in size, easy to carry, safe and reliable.

Description

technical field [0001] The invention relates to a safety belt suspension device for maintenance of a main transformer. Background technique [0002] Transformers with a voltage level of 110kV and above have a narrow platform and a large slope, and the safe range of activities for operators is small. When working on the main body, affected by the site and construction progress, scaffolding, aerial work vehicles and lift trucks cannot be used on site. As a safety measure against falling, only the safety belt can be used. When working on the main transformer, when encountering rainy weather or transformer oil remaining on the transformer shell, the maintenance personnel are easily slipped and injured; when the staff need to perform maintenance and maintenance on special position components such as the upper part of the heat sink and the on-load switch, etc. During the survey, the staff need to stand on the edge of the transformer shell to complete the maintenance, but such a w...
