Abstract
The invention discloses a clamping device of a transformer upper iron yoke and a clamping method thereof; according to different sizes of the transformer upper iron yoke, a bolt hole with the left body and the right body transversely corresponding is selected and a pin is arranged so as to cause the opening distance to be slightly larger than the diameter of the transformer upper iron yoke; later an iron core clamping plate at the right side of the diameter of the upper iron yoke is leaned against a fixing presser foot of the right body; an iron core clamping plate at the left side of the diameter of the upper iron yoke is opposite to the jack of the right body; the distance between the jack and the left iron core clamping plate is adjusted to the minimum; then the opening angle of four leg beams and the height of the upper legs of the leg beams are adjusted so as to lead the legs to evenly fall down on four points of the upper side of the iron core clamping plate at two sides of the upper iron yoke; and finally, the hydraulic system of the jack is opened so as to cause the jack to exert pressure on the left iron core clamping plate of the upper iron yoke, fasten the iron core clamping plate at the two sides of the upper iron yoke, and then fasten the bandage of the upper iron yoke of the iron core clamping plate. The opening distance of the clamping device can be adjusted and can change along the diameter specification of the iron core of the transformer, and therefore the using scope of the clamping device is enlarged.
Description
Technical field
The present invention relates to a kind of clamping device and clamping means of iron yoke on transformer.
Background technology
After transformer core upper yoke inserted sheet is finished, need the upper yoke lamination is tightened up.Former method utilizes the upper yoke strutting piece to strain iron core, perhaps clamps with simple and easy portal frame, so just has that clamping force unshakable in one's determination is uncontrollable, clamping force is inhomogeneous, complicated operation.And along with transformer capacity is increasing, the diameter of transformer core is also along with increasing, and what have clamping device now opens span from not regulating, and therefore can not change along with the variation of transformer core diameter specifications, has limited its scope of application.
Summary of the invention
The problems referred to above at existing clamping device, the invention provides a kind of open span in 700～2600mm adjustable range, the clamping device and the clamping means of clamping force adjustable iron yoke on transformer in 200 tons of scopes, can satisfy the demand of upper yoke different-diameter in the current transformer production fully.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of clamping device of iron yoke on transformer, comprise by left and right body and constitute a portal frame of opening stall space relatively, it is characterized in that, left and right body upper edge is respectively equipped with a plurality of pin holes with same horizontal straight line, select the laterally relative pin hole of left and right sides body and latch is set, can make left and right body be interconnected to constitute an adjustable stall space of opening of distance; Both sides are respectively equipped with two adjustable supporting leg beams of opening angle before and after the described left body, and each supporting leg beam end is provided with a Height Adjustable supporting leg; Describedly open that right body inboard is provided with fixing presser foot in the stall space; The left body inboard of opening relative this fixing presser foot in the stall space is provided with jack.
Two jack of described jack for relatively moving up and down along left body inboard.Described supporting leg beam and left body are hinged, and can do the plane along pin joint and rotate to regulate the opening angle of left body front and back two side leg beams.The pin hole that described selection left and right sides body is laterally relative and latch is set is by the screw rod realization that is connected with right body by the turning handle that is arranged on the left body outside and screw thread pair.
A kind of clamping means with aforementioned clamped device realization iron yoke on transformer comprise the steps:
1) according to the different size of iron yoke on transformer, select the laterally relative pin hole of left and right sides body and latch is set, open the retaining distance between the right body of coarse adjustment and the left body, make out retaining apart from the diameter that is a bit larger tham iron yoke on transformer;
2) clamping device is placed on the iron yoke on transformer, and upper yoke diameter right side clamping plate unshakable in one's determination are leaned against on the fixing presser foot of right body; The jack of the left relatively body of upper yoke diameter left side clamping plate unshakable in one's determination is regulated jack and is made distance minimum between the clamping plate unshakable in one's determination of itself and left side;
3) adjust the opening angle of four supporting leg beams and the height of supporting leg beam upper supporting leg, make supporting leg evenly fall within four points of clamping plate unshakable in one's determination top, upper yoke both sides;
4) open the hydraulic system of jack, jack pair upper yoke left side clamping plate unshakable in one's determination are exerted pressure, tighten up upper yoke both sides clamping plate unshakable in one's determination, then to tightening up the upper yoke bandage of clamping plate unshakable in one's determination.
5) close the jack hydraulic system, the time jack reset the removal clamping device.
The present invention's advantage compared to existing technology is:
1, according to different size transformer and upper yoke diameter dimension, optimization is provided with a plurality of pin holes position on left body, and the upper yoke of clamping device virtually any size in 700～2600mm scope can be used.
2, four supporting leg beams and 4 supporting legs are set on the left body, height of landing leg can be regulated, and can swing by the supporting leg beam, guarantees that any at grade four points can stand, and is used for supporting clamping device, reduces the driving holding time.
3, clamping device of the present invention is simple in structure, easy to use, and body adopts the double-layer high strength steel plate structure, both can guarantee structural strength and stability, can alleviate this body weight again.
The inventive method open span from can regulating, therefore can change along with the variation of transformer core diameter specifications, enlarged its scope of application.Adopt the handle screw thread pair to regulate and open the retaining distance, save time, laborsaving, light, easy to operate, the technology cost is low.
