Description
Technical field
The utility model relates to the device that Transformer Winding compresses winding in process of vacuum drying.
Background technology
Transformer Winding is in process of vacuum drying, must apply constant thrust to winding, with the mechanical strength of raising winding and the stability of physical dimension, strengthen the anti-short circuit capability of winding, simultaneously, can avoid adopting winding after vacuumize, to use the operation of coil press machine compression winding, to enhance productivity.
At present, the hold down gag that winding adopts in process of vacuum drying is hydraulic test, although this hydraulic test can apply constant thrust to winding, but this device structure is complicated, and is bulky, expensive, and need to be serviced maintenance, increased the production cost of Transformer Winding, and the clamping operation of winding on hydraulic test bothers time and effort consuming very much.
Summary of the invention
The purpose of this utility model provides a kind of dry constant-voltage equipment of Transformer Winding simple in structure, when Transformer Winding is carried out vacuumize, can apply lasting and constant thrust to winding.
The dry constant-voltage equipment of Transformer Winding described in the utility model, comprise platen, pressing disc, pull bar, force transmission rack and foot rest, described foot rest has three at least, its outer end is equipped with roller, it is inner hinged with force transmission rack, foot rest is evenly arranged on the force transmission rack, the inner of foot rest is also by bearing pin and strip pin-and-hole and pressing disc bottom-hinged, make foot rest and force transmission rack be positioned at pressing disc under, the pin joint of foot rest and pressing disc between the pin joint and roller of foot rest and force transmission rack, and the pin joint of foot rest and pressing disc apart from the distance of roller greater than the pin joint of foot rest and the pressing disc distance apart from the pin joint of foot rest and force transmission rack; The outer end of force transmission rack is set on the lower end of pull bar, and the pull bar lower end is connected with nut, and is positioned at the force transmission rack below, and upper platen is positioned at directly over the pressing disc, and it is set on the pull bar upper end, and the pull bar upper end is connected with nut, and is positioned at the platen top.
Described upper and lower platen is the circular discoid body, described force transmission rack is cross, be wholely set four the first articulated slabs that are the cross layout at the force transmission rack center, four the first articulated slabs are positioned at the plane at force transmission rack place, its whole and force transmission rack angle at 45 °, foot rest is inner hinged by the first articulated slab and force transmission rack; Four the second articulated slabs have been wholely set in the bottom surface of pressing disc, offer the strip pin-and-hole on it, foot rest is inner hinged by this strip pin-and-hole and bearing pin and the second articulated slab, and described pull bar has four, and upper and lower platen lays respectively at the up and down two ends of pull bar and between four pull bars.
Be welded with limit shaft sleeve in the force transmission rack center upper surface, be welded with spacing collar at the pressing disc center, limit shaft sleeve is positioned at spacing collar and spacing collar matched in clearance, presses moving radially of relative force transmission rack with the restriction pressing disc.
The clamping operation of Transformer Winding on this hold down gag is as follows:
First upper platen is taken off from this hold down gag, Transformer Winding is placed on the pressing disc, put again platen, make winding between upper and lower platen, then screw on the nut (this moment, nut can screw) of pull bar upper end.With driving lifting this hold down gag (lifting rope of driving is connected to the pressing disc edge), make this hold down gag unsettled.Foot rest is sagging because of self gravitation in this process, and drives force transmission rack and move up, and the nut with the pull bar lower end screws afterwards, and winding is clamped between the upper and lower platen.Then with this hold down gag handling to the vacuum drying tank flatcar, and put down.Hold down gag is in putting down process, and the roller of foot rest outer end contacts to earth, and along with the gradually decline of hold down gag, the inner of foot rest is surperficial near the vacuum drying tank flatcar gradually, thereby foot rest is rotated, until hold down gag is placed on the vacuum drying tank flatcar.In this process, force transmission rack moves down with hold down gag, the pin joint of foot rest and force transmission rack rotates (bearing pin slides in this process) in the strip pin-and-hole around the hinging pin shaft of foot rest and pressing disc simultaneously, distance between force transmission rack and the pressing disc is increased, thereby the nut that makes force transmission rack pass through its below spurs pull bar downwards, pull bar again the nut by upper platen top with upper platen to pressing down, thereby winding is pressed between the upper and lower platen.
Because the suffered thrust of Transformer Winding is caused by hold down gag described in the utility model and winding self gravitation, so this thrust is lasting and constant, according to lever principle, the suffered thrust of winding is the multiple of hold down gag and winding self gravitation, so winding is compressed in vacuumize reliably.This hold down gag only is comprised of limited several parts, and with respect to hydraulic test, structure is very simple, and installation cost is extremely cheap, and the clamping of winding is simple to operation.
