Abstract
The utility model relates to a kind of railway goods train bogie oblique wedge vibration damper tool special for dismounting, it is characterized in that: this oblique wedge vibration damper tool special for dismounting comprises a steel pipe, one first steel plate and one second steel plate; One end of described steel pipe is upwards vertical is welded and fixed described first steel plate, and the other end of described steel pipe lets droop to being welded and fixed described second steel plate.The utility model structural design is simple, has made conveniently, can be widely used in the dismounting decomposable process of railway freight-car control type bogie.
Description
Technical field
The utility model relates to a kind of tool special for dismounting, particularly about a kind of railway goods train bogie oblique wedge vibration damper tool special for dismounting.
Background technology
In railway freight-car control type bogie decomposable process, the wedge in vibration absorber is needed to compress along longitudinal direction of car, make to produce gap between wedge and side frame column wearing plate, be separated with bolster to facilitate side frame, and wedge top and side frame beam gap of winding up is less, be not suitable for designing disassembling fixture that is electronic or hydraulic means.If but wedge does not compress before decomposing by bogie in advance, the spring pressure in wedge makes side frame be difficult to disassemble from bolster.
Therefore, in control type bogie decomposable process, need to compress the wedge in vibration absorber, make to produce gap between the main rubbing surface of the wedge of bolster both sides and side frame column wearing plate, so that being separated of side frame and bolster.For this reason, control type bogie wedge tool special for dismounting is specifically designed in the urgent need to designing one.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of structure railway goods train bogie oblique wedge vibration damper tool special for dismounting simple, easy to use.
For achieving the above object, the utility model takes following technical scheme: a kind of railway goods train bogie oblique wedge vibration damper tool special for dismounting, is characterized in that: this tool special for dismounting comprises a steel pipe, one first steel plate and one second steel plate; One end of described steel pipe is upwards vertical is welded and fixed described first steel plate, and the other end of described steel pipe lets droop to being welded and fixed described second steel plate.
Further, the diameter of described steel pipe is 40mm, and length is 1100mm.
Further, the length of described first steel plate is 310mm, and width is 75mm, is highly 20mm; The length of described second steel plate is 310mm, length is 100mm, is highly 20mm.
The utility model is owing to taking above technical scheme, and it has the following advantages: the utility model comprises steel pipe, the first steel plate and the second steel plate, one end of steel pipe is upwards vertical is welded and fixed the first steel plate, the other end of steel pipe lets droop to being welded and fixed the second steel plate, during use, the first steel plate is positioned over bolster and side frame winds up between beam, dismounting personnel tramp with one's feet the second steel plate, principle compression wedge is expanded by the moment of lever, after the fabrication hole of wedge side overlaps with bolster fabrication hole, in fabrication hole, insert a crooked chisel fix wedge, now two wedge working face spacing are less than side frame column wearing plate spacing, take out the utility model, side frames can be separated with bolster easily, therefore, the utility model structure is simple, easy to use, can be widely used in the dismounting decomposable process of railway freight-car control type bogie.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1;
Fig. 3 is existing control type bogie structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description is carried out to the utility model.But should be appreciated that being provided only of accompanying drawing understands the utility model better, they not should be appreciated that paired restriction of the present utility model.In description of the present utility model, it is to be appreciated that term " first ", " second " are only used for the object described, and instruction or hint relative importance can not be interpreted as.
As shown in Figure 1 and Figure 2, the railway goods train bogie oblique wedge vibration damper tool special for dismounting that the utility model provides, it comprises steel pipe 1,1 first steel plate 2 and one second steel plate 3, one end of steel pipe 1 is upwards vertical is welded and fixed the first steel plate 2, and the other end of steel pipe 1 lets droop to being welded and fixed the second steel plate 3.
In a preferred embodiment, the diameter of steel pipe 1 is about 40mm, and the length of steel pipe is about 1100mm.
In a preferred embodiment, the length of the first steel plate 2 is 310mm, and width is 75mm, is highly 20mm; The length of the second steel plate 3 is 310mm, length is 100mm, is highly 20mm.
As shown in Figures 1 to 3, when the utility model uses, different according to the wind up gap of beam 4 of truck bolster for railway wagon and side frame, can by the first steel plate 2 or the second steel plate 3 be positioned over wedge 5 and side frame winds up between beam 4, in the present embodiment, the first steel plate 2 is positioned over wedge 5 and side frame winds up between beam 4, set up inside first steel plate 2 at wedge 5 top, outside and the side frame of the first steel plate 2 beam 4 that winds up contacts, now steel pipe 1 and the second steel plate 3 naturally droop, the first steel plate 2 that insertion bolster and side frame are winded up between beam 4 forms lever, now dismantle personnel pin to step on the second steel plate 3 and exert a force to the second steel plate 3, the spring-compressed in wedge inner chamber is made by lever principle, wedge 5 along the inclined-plane in bolster wedge groove downwards and move inward, after wedge fabrication hole overlaps with the fabrication hole on bolster, one crooked chisel is inserted fixing wedge, then the utility model is taken out, side frame and bolster can be decomposed, complete the disintegration of bogie.
The various embodiments described above are only for illustration of the utility model; wherein the structure of each parts, connected mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
