Description
Technical field
The present invention is for a kind of converter transformer valve side rising seat positioner and utilize this device that the method for converter transformer rising seat is installed.
Background technology
The outlet from the fuel tank end wall of the valve side of DC converter transformer; And become the angle of an inclination with oil tank wall; The position and the dimensional accuracy of outgoing line device rising seat are very big to the external insulation distance affects of sleeve pipe head, and two alternate relative position and angles directly influence the exterior insulation distance.Therefore, the making precision of valve side rising seat and relative position degree ERROR CONTROL are very crucial.Usually the method for taking on the industry is that the ring flange made allowance at rising seat two ends is made; Assembly welding finishes the back with the whole processing of the large-sized numerical control machining center seat that raises; Height, the angular error of control rising seat; And the anglec of rotation of on tank wall, installing, thereby reach the tolerance of exterior insulation distance.
The shortcoming of the method is, must go up large-scale numerical control machining center processing behind the seat assembly welding that raises, and device-restrictive and cost of processing are very high; Can only control the making precision of the seat that raises, and the seat that raises is uncontrollable with the rigging position precision of tank wall, the error after the moulding assembling does not have foresight and regulatable space.
Summary of the invention
The objective of the invention is to: disclose the method that a kind of converter transformer valve side raises the seat positioner and uses this device installation converter transformer rising seat; Thereby realize accomplishing the installation of converter transformer and similar mechanism, thereby realize purpose with low cost and easy operating and realization with simple mechanism and method.
Converter transformer valve side among the present invention seat positioner that raises comprises a tank wall locating flange that is fixed with the seat angle location pipe that raises, the central locating rod two ends of the seat that raises respectively with raise seat angle location pipe and sleeve pipe center simulative tube is connected and through location structure it is located in twos respectively.A positioner that raises of the present invention can be confirmed the position and the angle of inclination thereof of rising seat lower end through the seat angle location piece that raises.Simultaneously, through the angle of the accurately definite seat that raises of a rising central locating rod, and the sleeve pipe simulative tube that utilization simultaneously is connected with central locating rod is confirmed the relative position of sleeve pipe and rising seat and is guaranteed its angle of inclination.
In the process that the seat that raises is installed, for guaranteeing accurately to confirm the angle and the position of sleeve pipe, the seat central locating rod that can raise is provided with the sleeve pipe afterbody locating piece of analog casing tapering.This sleeve pipe afterbody locating piece can be made up of the round platform of two different-diameters that with the central locating rod is axle at least, the position and the angle of the virtual cones analog casing that is made up of the line of two round platform end faces.Because the position of its sleeve pipe of converter transformer of different parameters is different,, then need multiple different fixed that the rising seat backstay of sleeve pipe afterbody locating piece is arranged if sleeve pipe afterbody locating piece is fixed on the seat backstay that raises.For adapting to different needs, and reduce cost, sleeve pipe afterbody locating piece is sleeved on the central locating rod, and central locating rod is provided with the locating piece detent mechanism that is mated, thereby realizes adjustable.The locating piece detent mechanism specifically can be following form: it comprise be arranged on central locating rod middle part, along one group of pin shaft hole of central locating rod length direction; And having the interfix pin to insert in the pin shaft hole, its part that protrudes in pin shaft hole cooperates with the lower surface of sleeve pipe afterbody locating piece.
For whole rising seat central locating rod; It with other parts between be connected all and can adopt adjustable form; For example: top, middle part and top at central locating rod are respectively arranged with one group of pin-and-hole along its length direction; Insert respectively in raise seat angle location pipe and the sleeve pipe center simulative tube at the two ends of central locating rod; The ledge that is inserted in the interior last alignment pin of central locating rod top, middle part and lower pin axis hole, interfix pin, following alignment pin cooperates with raise a seat angle location pipe upper surface, the lower surface of sleeve pipe afterbody locating piece and the lower end of sleeve pipe center simulative tube respectively, makes the each several part location.
Undertaken by following step when utilizing above-mentioned rising seat positioner to install to raise seat: it may further comprise the steps: (a) be fixed on the tank wall locating flange by raise a seat design attitude and angle angle location pipe that will raise; (b) by the design attitude and the angle of the seat that raises itself and transformer body are carried out trial assembly, and carry out preliminary coarse localization; The tank wall locating flange that (c) will be fixed with the seat angle location pipe that raises is fixed in the rising seat puts corresponding transformer-cabinet inboard; (d) the sleeve pipe locating flange is installed on the upper surface of seat that raises, and fixes; (e) behind the design attitude mounting sleeve afterbody locating piece on the central locating rod, central locating rod is assemblied in the seat that raises, the seat lower surface that will raise is again fixed in its lower end insertion rising angle location pipe with after the tank wall of fuel tank body cooperates; (f) mounting sleeve center simulative tube makes its apical position identical with the sleeve pipe physical location; (g) will raise seat through the firm welding location; (h) after the solder joint cooling, remove central locating rod, sleeve pipe afterbody locating piece and sleeve pipe center simulative tube.
In above step, be convenient installation, the tank wall locating flange and the seat lower flange that raises can be designed to spoke structure, so that carry out the installation between central locating rod and the rising seat angle location pipe through the hole on the tank wall locating flange and the seat lower flange that raises.
In addition, be handled easily,, before the mounting center backstay, preestablish alignment pin, interfix pin and the position of alignment pin down, and be inserted on the central locating rod accordingly in the pin shaft hole according to the length of designing requirement, the seat angle location pipe that raises.
In operating procedure of the present invention, earlier the rising seat has been carried out preliminary coarse localization, again with its firm welding location, wherein, the preliminary coarse localization of the described seat that raises is to make the rising seat and the seat lower flange that raises carry out the rough welding location of part point; Described rising seat firm welding location is meant on the basis of above-mentioned rough welding, and the seat that will raise welds with the whole tie points of seat lower flange that raise.
The invention discloses the method for a kind of simple rising seat installing and locating mechanism and this mechanism's installation valve side rising seat of use.There is not the large-sized numerical control machining center to carry out under the situation of whole processing; Through this mechanism and method can under the prerequisite that guarantees precision, raise the easily location and the installation of seat; Thereby the production cost that reduces greatly, and can save the set-up time, enhance productivity.
