Embodiment 1

[0024] Example 1: See Figure 1 to Figure 7 , the interchangeable track ballast hopper car in this embodiment includes a vehicle body and an underframe, the vehicle body is arranged on the underframe, and an upper side bearing 1 and a center plate are provided on the side of the underframe away from the vehicle body, and the center plate is used for connecting The bogie 5, the end of the upper side bearing 1 away from the underframe is used to resist the bogie 5; the upper side bearing 1 includes the upper side support body 12 on the standard rail, the upper side support body 13 on the narrow rail, the adjustment backing plate 14 and the wear plate 15. The underframe also includes a corbel lower cover for receiving the vehicle body. One end of the side rail upper side support 12 is fixed on the corbel lower cover 11, and the other end is provided with a narrow rail upper side support 13 and fixed on the Below the lower cover plate 11 of the bolster; the adjustment backing plat...

Embodiment 2

[0025] Example 2: see figure 1 and Figure 6, the vehicle body of this embodiment includes a funnel 2, a side wall 3 and an end wall, the side wall 3 and the end wall are enclosed to form a loading cavity, and the side wall 3 is provided with an observation hole for observing the inside of the loading cavity. The bottom is provided with a funnel 2 for unloading, and the funnel 2 includes a dovetail-shaped funnel mouth. The top of the funnel mouth is provided with a feed channel 21 for connecting the vehicle body, and a first discharge channel 22 and a second discharge channel are symmetrically arranged on both sides of the bottom of the funnel mouth. Discharge channel: the first discharge channel 22 gradually decreases along the discharge direction, the first discharge channel 22 is provided with a first discharge port on the side away from the feed channel 21, the first discharge port is in the shape of an arc, It also includes a first swing bottom door 23 for closing the fi...

Embodiment 3

[0026] Example 3: See figure 2 , image 3 and Figure 7 In the end wall of the present embodiment, along the direction in which the funnel 2 vehicles travel, an anti-shock device 6 is respectively arranged at the front and back ends, and the anti-shock device 6 is a tower-type three-dimensional structure welded by all steel. The manufacture is simple and the production cost is low. According to the dynamic analysis, the device can disperse the longitudinal impact force of the vehicle body and greatly improve the impact resistance of the vehicle body. In the design of the body structure, it has the effect of "one or two strokes". The vehicle body of this embodiment also includes an underframe 4, the underframe 4 is used for carrying funnels, side walls 3 and end walls, the underframe 4 is provided with a load-bearing center beam 41, the load-bearing center beam 41 is a dumbbell-shaped structure, and the load-bearing center beam 41 The diameter at both ends is larger than t...

Abstract

A rail-replaceable stone ballast hopper car comprises a car body and a bottom frame; the car body is arranged on the bottom frame; an upper side bearing and a center plate are arranged on the side, away from the car body, of the bottom frame; the center plate is used for being connected with a bogie, and the end, away from the bottom frame, of the upper side bearing abuts against the bogie; the 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 bottom frame further comprises a sleeper beam lower cover plate used for bearing the car 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 upperside bearing body is provided with a 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 and used for adjusting the heights of the standard gauge upper side bearing body and the narrow gauge upper side bearing body, and a wearing plate is arranged at the bottom of the adjustingbase plate and abuts against the bogie; the standard gauge upper side bearing body is added during standard gauge operation, and a standard gauge bogie is used; and in case of narrow gauge running, the standard gauge upper side bearing body is detached, and the narrow gauge upper side bearing body is reserved and a narrow gauge bogie is used.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a ballast hopper car with interchangeable rails. Background technique [0002] At present, ballast hopper cars operating on domestic and foreign railways have various structures. In order to meet the requirements of working conditions in specific environments, there are different types of loads, unloading methods, and different gauges. According to the railway gauge: there are narrow-gauge ballast hopper cars suitable for gauge 1067mm, standard-gauge ballast hopper cars suitable for gauge 1435mm, and wide-gauge ballast hopper cars suitable for gauge 1520mm. The specific gauge requires that this type of vehicle can only run on a specific line, which has great limitations and a small application range. Therefore, be badly in need of a kind of ballast hopper car that can carry out rail changing operation and be applicable to narrow gauge and quasi-gauge simultaneously, thereby im...
