Embodiment
Below by composition graphs 1-3, by instantiation, the present invention is described in detail.
By with upper type, those skilled in the art can make various change according to mode of operation within the scope of the invention.
According to embodiment, a kind of gear drive and be convenient to the transformer of demolition and maintenance, comprise containing core-coil assembly and the lead-in wire device body 1 of (not shown), device body pedestal 2 and installing rack 3, wherein, succinctly and be not described the concrete parts of transformer body 1 to describe, it is for means as known in the art or adopt these known approaches, the bottom side of described installing rack 3 is used for laying building body with transformer and is fixedly connected with, described device body pedestal 2 is fixedly connected on the bottom of described device body 1, and comprise at least two pedestal bars 20, each pedestal bar 20 has protrusion junction surface 24 and below described protrusion the junction surface 24 and in the direction of the width outward extending width extension 241 on top, the upside of described width extension 241 is covered with cushion 23, the left and right sides is covered with lateral elastic pad 22, downside is provided with two rollers 21, the bottom of described pedestal bar 20 is provided with inverted U-channel 240 and passes with for drive screw 34 gap between described two rollers 21, the upper side at described protrusion junction surface 24 be provided with fastening screw 25 in order to engage bottom described device body and be fastenedly connected, both sides place on the longitudinally of each described pedestal bar 20 is respectively arranged with the release slide block 342 of described drive screw 34 threaded engagement and advances slide block 341, the right-hand member of drive screw 34 each in described at least two pedestal bars 20 is provided with pinion 35, in two described pinions 35, the right side power of is connected with motor 351, speed changer 353 is provided with between described motor 351 and described pinion 35, wherein, also be provided with gear wheel 352 between two described pinions 35 thus make the run-in synchronism of two described pinions 35,
