A kind of adjustment height gilled radiator bracing frame
Technical field
The present invention relates to a kind of adjustment height gilled radiator bracing frame, particularly a kind of bracing frame that is used to support gilled radiator on the self cooled transformer.
Background technology
At present, the capacity of self cooled transformer is increasing now, and by original 110kV, 50MVA has developed into 220kV, 180MVA even bigger capacity.The high-power transformer loss is big, needs bigger gilled radiator centre-to-centre spacing and sheet number, and the heat that produces during the operation of ability balancing transformer meets the demands oily temperature.The deadweight of this gilled radiator and charge of oil are heavy very high, the suspension force of simple tube joint is difficult to keep, and is can distortion after operation a period of time sagging, makes butterfly valve unbalance stress up and down, the sealing gasket distortion causes the leakage of oil of butterfly valve place, therefore need effectively support the gilled radiator bottom.Former support adopts vertical rod to support, with pad adjustment height, this supporting way is inconvenient to adjust height, and can not produce a pre-jacking force that makes progress to gilled radiator during installation, support elastic distortion after the gilled radiator oiling still can make butterfly valve unbalance stress up and down.
Summary of the invention
For solving above technical deficiency, the invention provides and a kind of gilled radiator is produced a pre-jacking force that makes progress, offset the sagging that the support elastic distortion produces after the oiling, and to adjustable for height gilled radiator bracing frame.
The present invention is achieved by the following measures:
A kind of adjustment height gilled radiator bracing frame of the present invention, be positioned at the gilled radiator bottom, comprise base, lower supporting plate and upper backup pad, lower supporting plate is connected base top and center fixation has locking nut, upper backup pad is connected the gilled radiator bottom, but the upper backup pad center vertically is connected with the adjusting screw(rod) of axial rotation, and described adjusting screw(rod) matches with locking nut and forms the screw screw structure, is connected with the anti-dumping screw rod between upper backup pad and the lower supporting plate.
Adjustment height gilled radiator bracing frame of the present invention, the adjusting screw(rod) surface is provided with clamping part, and described clamping part is provided with at least two planes.
Adjustment height gilled radiator bracing frame of the present invention, described anti-dumping screw rod is four, lays respectively at upper backup pad and lower supporting plate four jiaos.
The invention has the beneficial effects as follows: after gilled radiator is installed, by adjusting bearing height, gilled radiator is produced a pre-jacking force that makes progress, after the gilled radiator oiling, this pre-jacking force can be offset because of oil heavily causes support elastic and is out of shape produce slightly sagging, thoroughly solves the diffusing butterfly valve of the sheet situation of unbalance stress up and down.
Description of drawings
Fig. 1 is the diffusing schematic diagram that supports of vertical rod sheet of the present invention;
Among the figure: 1, gilled radiator, 2, base, 3, lower supporting plate, 4, upper backup pad, 5, locking nut, 6, adjusting screw(rod), 7 anti-dumping screw rods, 8 clamping parts.
Embodiment
As shown in Figure 1, a kind of adjustment height gilled radiator bracing frame of the present invention, be positioned at gilled radiator 1 bottom, comprise base 2, lower supporting plate 3 and upper backup pad 4, lower supporting plate 3 is connected base 2 tops, and the center fixation of lower supporting plate 3 has locking nut 5, upper backup pad 4 is connected gilled radiator 1 bottom, but upper backup pad 4 centers vertically are connected with the adjusting screw(rod) 6 of axial rotation, adjusting screw(rod) 6 matches with locking nut 5 and forms the screw screw structure, is connected with anti-dumping screw rod 7 between upper backup pad 4 and the lower supporting plate 3.Adjusting screw(rod) 6 surfaces are provided with clamping part 8, and clamping part 8 is provided with at least two planes, are convenient to tool holding and live adjusting screw(rod) 6 rotations.Anti-dumping screw rod 7 adopts four, lays respectively on upper backup pad 4 and lower supporting plate 3 four jiaos.
Occupation mode of the present invention is, base 2 places on the platform of placing transformer, unclamps the adjusting screw(rod) 6 of having locked, and anti-dumping screw rod 7 is unclamped, clamp clamping part 8 rotation adjusting screw(rod)s 6 with instrument, adjusting screw(rod) 6 rotates in locking nut 5, thereby makes adjusting screw(rod) 6 vertical lifts, and then regulates the distance between upper backup pad 4 and the lower supporting plate 3, when reaching suitable distance, bracing frame supports gilled radiator 1, tightly lives again with adjusting screw(rod) locking, and with anti-dumping screw rod 7.Anti-dumping screw rod 7 is given traction force of upper and lower support plate, can prevent that gilled radiator 1 to lopsidedness, having improved stability.Can regulate according to the concrete condition that transformer is placed.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection range of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
