Abstract
The utility model discloses a hoisting bracket for an on-load voltage regulation switch of a transformer, comprising a base, an upright post and a cross beam which are connected into a whole, wherein the base is provided with fixing holes; the upright post is stretchable and consists of an upper section, a middle section and a lower section, the bottom end of the lower section thereof is fixedly connected with the base, the top end of the upper section thereof is fixedly connected with the cross beam, and the middle section thereof is moveably connected with the upper end and the lower end; and the cross beam is provided with a hanging ring. The hoisting bracket for the on-load voltage regulation switch of the transformer is mainly used for a suspended core during the overhauling of the on-load voltage regulation transformer, and has the advantages of simple structure, light weight, convenient use and installation, and the like.
Description
Technical field
The utility model belongs to the Repair of Transformer technical field of tools, specifically relates to a kind of on-load tap-changer of transformer mast-up.
Background technology
On-load tap-changing transformer according to the length of its running time and switch deciliter action frequency what, must in time overhaul, safeguard on-load tap-changer of transformer, with the support equipment safe operation, ensures power supply reliability.During the maintenance on-load tap-changer of transformer, the general crane that uses carries out suspended core, there is the shortcoming of several respects in this hanging method, and the one, because crane is relatively heavier, suspended core weight compares less, the bad grasp of lifting dynamics, usually too quickly because of lifting by crane, cause the damage of on-load voltage regulating switch moving contact and body, the transformer high and low pressure porcelain bushing of also can damaging sometimes, cause device damage, influence the safe operation of converting equipment.The 2nd, limited by the place, influence construction schedule and safety.The 3rd, the recondition expense height, unnecessary waste is more serious.Application number is that 200810138455.4 Chinese invention patent application discloses a kind of on-load tapping switch hanger, though this suspension bracket can be used for the maintenance of on-load tap-changer of transformer, exists this volume big, and heaviness is used shortcomings such as inconvenience.
Summary of the invention
The technical problems to be solved in the utility model provides the on-load tap-changer of transformer hoisting bracket that a kind of volume is little, in light weight, be convenient to install.
For solving the problems of the technologies described above, the utility model comprises base, column and the crossbeam that is connected as a single entity, and its design feature is that described base is provided with fixing hole; Described column is a telescopic column, and it is made up of for three sections upper, middle and lower, and its hypomere bottom and base are fastenedly connected, and its epimere top and crossbeam are fastenedly connected, and its stage casing and upper/lower terminal flexibly connect; Described crossbeam is provided with link.
Described base is curved.
The hypomere of described column and epimere in a tubular form, the stage casing is a shank, it and hypomere and epimere are pegged graft, be equipped with the vertical column expanding location hole on the hypomere of column and the stage casing, be provided with bolt in the location hole, the column epimere is provided with angle adjustment holes, is provided with the positioning bolt in the adjustment hole.
The utility model is made up of base, telescopic column and crossbeam, and is simple in structure, in light weight.Base is provided with fixing hole, utilizes bolt it can be fixedly secured on the on-load voltage regulating switch top cover, and is easy for installation.During maintenance, jack hangs over crossbeam link place, can easily on-load tap-changer of transformer be hung out.Column is a syllogic, can adjust column height and crossbeam angle easily, and is easy to use.
