Description

Reactor iron core roll-over stand

Technical Field

The utility model relates to a transformer technical field, in particular to reactor iron core roll-over stand.

Background

In the production and manufacture of the reactor, silicon steel sheets are required to be rolled into a plurality of annular cakes, and a plurality of annular cake-shaped steel sheets (also called iron cores) are sequentially stacked in the height direction. In the past, when a reactor core is stacked in a workshop, the reactor core is vertically stacked and stacked directly on a reactor bracket without safety protection (generally, the iron cores stacked on each bracket are in the same specification, that is, the iron cores with different specifications are stacked on different brackets). Such an operation mode needs 2 people cooperation (1 people ground transport, 1 people high altitude stack) at least and carries the iron core to the high altitude (more than 2 meters) from ground, and workman intensity of labour is big, and is consuming time and wasting power to the reactor can produce serious incident if the upset, has very big potential safety hazard. The utility model patent of patent No. CN200920071884.4, name are "an iron core roll-over table", its support fixing device include that the stem supports and sets up in the folder that this stem supported both sides and supports, at the closed assembly iron core in-process, earlier support the position that supports with the stem through the adjustment folder in order to satisfy the iron core of closed assembly to window height and the requirement of looks interval, place the folder on the folder supports, adjust the bolt that the folder supported and make folder and stem support on the coplanar, then carry out the iron core closed assembly. Although this patent has solved high altitude construction scheduling problem, but because the iron core is directly placed on iron core support fixing device, and this iron core supports fixing device can not adjust the width, when the iron core size of placing is great, there is two piles of iron cores of adjacent emergence collision phenomenon, therefore it is not suitable for with the iron core closed assembly of different specifications, and a plurality of iron core closed assembly finishes the back, only press from both sides the iron core on the whole support fixing device with interim clamping device clamp, and a pile of iron core that a plurality of iron core closed assembly on supporting to the stem, and lock the encapsulation alone, therefore this pile of iron core still is independent individual, the upset platform is changeing into the in-process of upright state by the horizontal state, the iron core still can roll or drop, the potential safety hazard is still not eliminated.
