As preferably; Described bracing frame comprises the support bar of vertical setting; Described montant inner hollow, montant lower end sidewall is provided with steady pin, and described support bar and montant hollow wall are equipped with; Described support bar stretches into and forms secure fit in the montant, and described support bar is provided with some pin-and-holes that are equipped with steady pin.After adopting above-mentioned preferred version, can regulate the height of transformer tap changer maintenance lifting device, more correspond to actual needs according to actual conditions.
As preferably, described fixed mount is provided with fixed via, and described fixed via and bracing frame are equipped with.After adopting above-mentioned preferred version, the fixed effect of transformer tap changer maintenance lifting device is better.
As preferably, described montant is provided with the boom hoisting fixed platform, and described manual boom hoisting comprises rotating shaft, and described lifting rope is wound in the rotating shaft, and described rotating shaft is provided with operating grip.After adopting above-mentioned preferred version, the transformer tap changer of the utility model maintenance lifting device lifting better effects if.
The transformer tap changer maintenance lifting device of the utility model adopts single armed runing rest formula, with seamless steel pipe and the main manufacturing materials of hand gear reduction unit conduct; Support is divided into two, and is convenient to transportation, and upper part is the vertical loading board of special-purpose lifting device, and lower part is the bracing frame of special-purpose lifting device, and has designed support vertical loading board auxiliary equipment and instrument rotary supporting body respectively.During lifting, the stressed maximum of suspension rod the first half, and the latter half is just played a supporting role; So generally the first half with vertical loading board is fixed on the switch housing flange; Consider in the transformer of multiple model that the horizontal range of switch housing flange and transformer case flange is all unequal, can't unify; Therefore, generally adopt adjustable fixation means.Operation is safe and reliable for ease, generally selects whole rotation mode for use.When the transformer tap changer maintenance lifting device of the utility model is installed, only need to install and fix about two people.One man operation hangs out transformer body through hand gear reduction unit with on-load voltage regulating switch, rotates special-purpose lifting device again, and on-load voltage regulating switch is released transformer body, and hand gear reduction unit drops to ground with on-load voltage regulating switch.
That the transformer tap changer of the utility model maintenance lifting device uses is simple, save time, laborsaving, safe and reliable requirement, has substituted the conventional artificial carrying, has effectively alleviated maintainer's labour intensity; Strengthened service ability; Powerful guarantee the safe and reliable operation of power equipment, the maintainer reduces, interruption maintenance time and lifting time shorten greatly; Improve the power supply reliability of electrical network, guaranteed user's normal electricity consumption.
