Embodiment 1

[0026] Example 1: See Figure 1 to Figure 3 , the upper side bearing of a kind of interchangeable railway freight car of the present embodiment, comprises the side bearing body 2 on the standard rail, the side bearing body 3 on the narrow rail, the adjustment backing plate 4 and the wearing plate 5; The side bearing body on the standard rail 2 is set under the lower corbel cover 1, the corbel lower cover 1 is used to receive the car body, the corbel lower cover 1 is a fixed part of the car body, and the side support body 2 on the standard rail One end is fixed on the corbel lower cover plate 1, and the other end is provided with the narrow rail upper side support body 3 and fixed under the corbel lower cover plate 1; the adjusting backing plate 4 is fixed on the quasi-rail Below the side support body 2 on the rail, the adjustment backing plate 4 is used to adjust the height of the side support body 2 on the quasi-rail, and the wear plate 5 is arranged at the bottom of the adju...

Embodiment 2

[0027] Example 2: see figure 1 , the side support body 2 on the quasi-rail of the present embodiment includes a first fixed plate 23, a first support plate 24 and a second fixed plate 25 connected in sequence, and the first fixed plate 23 and the second fixed plate 25 are respectively fixed on the corbel On the lower cover plate 1, the upper side support body 3 on the narrow rail is fixed between the second fixing plate 25 and the lower cover plate 1 of the corbel. The first fixing plate 23 of this embodiment and the lower cover plate 1 of the corbel are connected by bolts, the second fixing plate 25 is provided with studs 21 , the side support body 3 on the narrow rail is provided with the first screw hole, and the lower corbel The cover plate 1 is provided with a second screw hole, the stud 21 passes through the first screw hole and the second screw hole in turn, and the nut 22 is screwed into the stud 21, and then the side support body 3 on the narrow rail and the lower cov...

Embodiment 3

[0028] Example 3: See figure 1 , the side support body 3 on the narrow rail of this embodiment includes a third fixing plate 32 and a second supporting plate 31, the first screw hole is arranged on the third fixing plate 32, and one end of the third fixing plate 32 is connected to the second supporting plate 31 , the other end is used to resist the corbel lower cover 1 , and the end of the second support plate 31 away from the third fixing plate 32 is also resisted to the corbel lower cover 11 . In this embodiment, the third fixing plate 32 and the second supporting plate 31 are perpendicular to each other and have an integrated structure. The third fixing plate 32 is perpendicular to the second supporting plate 31, so that the bearing capacity of the third fixing plate 32 is stronger, and the stability of the overall structure of the side support body 3 on the narrow rail is ensured.

Abstract

The invention discloses a rail-changing wagon upper side bearing and a rail changing method for standard-gauge rail and narrow-gauge rail. The rail-changing wagon upper side bearing comprises a standard-gauge upper side bearing body, a narrow-gauge upper side bearing body, an adjusting base plate and a wearing plate. The standard-gauge upper side bearing body is arranged below a sleeper beam lowercover plate, the sleeper beam lower cover plate is used for bearing a vehicle body, the sleeper beam lower cover plate is a fixed component of the vehicle body, one end of the standard-gauge upper side bearing body is fixed to the sleeper beam lower cover plate, and the other end of the standard-gauge upper side bearing body is provided with the narrow-gauge upper side bearing body and fixed below the sleeper beam lower cover plate. The adjusting base plate is fixed below the standard-gauge upper side bearing body, the adjusting base plate can be of different thicknesses to adjust the heightof the standard-gauge upper side bearing body or the narrow-gauge upper side bearing body, and the wearing plate is arranged at the bottom of the adjusting base plate. For standard-gauge running, thestandard-gauge upper side bearing body is installed and a standard-gauge bogie is arranged; for narrow-gauge running, the standard-gauge upper side bearing body is detached, the narrow-gauge upper side bearing body is reserved, a narrow-gauge bogie is arranged; great convenience is achieved, and the effect of saving cost is achieved compared with changing of a whole wagon in the prior art.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a method for changing rails on side bearings and standard rails and narrow rails of rail freight cars. Background technique [0002] According to the different gauges, the rails are divided into standard gauge, wide gauge and narrow gauge; different regions may adopt different gauges. [0003] The existing one-piece cast structure or one-piece welded structure of the upper and side bearings of railway wagons in my country and abroad can only be adapted to the corresponding gauge, but cannot be replaced to work on other gauge tracks. Time-consuming and labor-intensive replacement is required, which also increases costs. Therefore, there is an urgent need for an upper side bearing that can be applied to different gauges. When changing rails, it is only necessary to slightly adjust the upper side bearing and replace the corresponding gauge bogie. Contents of the invention [00...
