Abstract
The utility model discloses a tool for assembling a transformer cabinet and a cooling oil pipe of an electric locomotive. A simulated pipeline is composed of steel pipes with square cross sections; a location flange is arranged on one end of the simulated pipeline, and is adaptive to a connection flange of a transformer cabinet pipeline; and the other end of the simulated pipeline is adaptive to a cooling oil pipe pipeline. By designing a special tool, the distance between the tail end of a transformer box pipeline and the connection joint of a cooling device is determined; the interchangeability and the universality of the transformer and the cooling device are improved in the locomotive maintenance process; and a cooling device connection pipe can be mounted smoothly under a condition of rigid connection. Therefore, the tool provided by the utility model is suitable for assembly of an electric locomotive transformer.
Description
Technical field
The utility model relates to the locomotive component technical field.
Background technology
Transformer is one of core component of electric locomotive, mainly fuel tank steel construction, transformer body two parts, consists of.The function of transformer is that the power frequency on contact line (25kV) high-tension electricity is changed into to the voltage that locomotive can be used.Fill with cold oil in oil tank of transformer, and by cooling device to produce the transformer cooling of heat in running.Oil in transformer flows into cooling device by the pipeline of transformer-cabinet outer wall, and cooled oil returns by pipeline again, works on.Therefore, the assembly quality of the sealing of transformer-cabinet pipeline and pipeline and cooling device, be all the key factor that affects the transformer function.Cold oil pipeline distribution situation is shown in Fig. 1, wherein direction change place of pipeline and all adopt flange to be connected with the junction of cooling device.
The mounting means of taking at present is, according to shape and the direction of pipeline, to rely on the connecting hose of cooling device outlet is carried out to the adjustment of length and locus, the flange of assembling transformer casing pipeline flange and cooling device.
Due in simmering the pipe process, the minute differences of fillet can cause the difference of length of pipe, and the heat input of flange welding process also can cause the distortion of pipe, in the situation that there is no assembly tooling, by the position of flange hole and the hose connector of adjustment cooling device, can complete assembling.Shortcoming one: any transformer-cabinet pipeline end is all different from the distance of cooling device junction, irregularities; Shortcoming two: the interface of cooling device is becoming in rigidly connected situation, and assembling can't complete; Shortcoming three: cause the transformer changed in maintenance process in the future and cooling device outlet connecting pipe road without versatility, impact is used.
The utility model content
The technical problem that the utility model solves is to provide electric locomotive transformer casing and the oil cooling service pipe tool for assembling that a kind of assembly precision is high.
The technical solution adopted in the utility model is, electric locomotive transformer casing and oil cooling service pipe tool for assembling, comprise the simulation pipeline, it is characterized in that: described simulative tube route cross section is that square steel pipe forms, one end of simulation pipeline is provided with locating flange, the adpting flange of locating flange and transformer-cabinet pipeline is suitable, and the other end and the oil cooling service pipe pipeline of simulation pipeline are suitable.
The beneficial effects of the utility model are, by formulating special tooling, to determine the distance of transformer-cabinet pipeline end and cooling device junction; Solve the problem that is difficult to regulate cooling device tube connector distance in the locomotive assembling process, save man-hour; Interchangeability and the versatility of transformer and cooling device in raising locomotive maintenance process; Guarantee the smooth installation of cooling device tube connector in the situation of being rigidly connected, for the production maintenance of locomotive has reduced cost.
The accompanying drawing explanation
Fig. 1 is transformer-cabinet pipeline size figure.
Fig. 2 is a-quadrant partial enlarged drawing in Fig. 1.
Fig. 3 a is the frock sketch.
Fig. 3 b is the left view that Fig. 3 a is corresponding.
In figure, be labeled as: 1-simulates pipeline, 2-locating flange, 3-mount pad hole, 10-the first center line, 11-the second center line, 13-transformer-cabinet pipeline center line.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, with the transformer of following a kind of model as example, as shown in Figure 1 and Figure 2.
1. determine the assembling process location dimension.By according to drawing requirement, the adpting flange outer surface of cooling device pipe interface and transformer-cabinet pipeline distance the first center line 10 distances are 575mm; Cooling device pipeline and transformer-cabinet pipeline center line 13 should be on the same center lines, and distance the second center line 11 distances are 1145mm, as shown in Figure 1.
2. according to the analysis to the assembling process location dimension, determine the positioning datum of frock.Because the processing in transformer box edge hole, mount pad hole is that to take two center lines be benchmark, therefore, frock selects to using four holes of seat board one side as positioning datum.Cooling device connecting line and transformer-cabinet pipeline center line 13 distance two centerline hole distances are " 1145mm " size in Fig. 1 during " 635mm " can guarantee; Another distance between center line transformer-cabinet adpting flange outer surface distance of two holes is 835mm, can guarantee the dimensional requirement of " 575mm " in Fig. 1.
3. draw the frock drawing, as shown in Figure 2.
4. making frock.For the positioning precision in the mount pad hole 3 that guarantees the frock seat board, select drilling machine boring; For guaranteeing the position of frock center line, the selecting party pipe profile is as simulation pipeline 1, and square tube has enough intensity, can guarantee the stability of frock, determines more accurately position of center line, is convenient to support.
The concrete operations engineering is as follows:
1. with bolt, frock is fixed on transformer mount pad hole, locating flange 2 on frock has guaranteed that the adpting flange outer surface of cooling device pipe interface and transformer-cabinet pipeline is 575mm apart from the first center line 10 distances, simultaneously, also guaranteed cooling device connecting line and transformer-cabinet pipeline center line 13 size apart from the second center line 11 " 1145mm " of casing.
2. with bolt, union one side flange is connected with the locating flange 2 of frock, guarantees that the union center line overlaps with the center line of the simulation pipeline 1 of frock, has determined the spatial position precision of union.Adjust the position of bend pipe flange and union flange, measure the distance of two flange holes, determine the length that union bedding-in place will cut.
3. take off union, according to the length of measuring, cutting union bedding-in place, to requiring length, completes welding and the bedding-in of union and flange.
