[0019] EMBODIMENT

[0020] In order to make the utility model clearer and more apparent, the railway flat car shallow spherical heart disc fixing device of the utility model is further described below in combination with the drawings, and the specific embodiments described herein are only used for explaining the utility model and do not limit the utility model.

[0021] Referring to Figure 2 and Figure 3 A railway flat car shallow spherical heart disc fixing device is characterized in that:

[0022] Includes a through hole 1a opened on the transition trolley 1. The through hole 1a is set along the central axis of the upper center plate 11 and the lower center plate 12. A through pin 2 is provided in the through hole 1a. The top of the through pin 2 extends upward out of the through hole 1a and is fixed with a through pin cap 3. The bottom of the through pin 2 extends downward out of the through hole 1a and is provided with a through pin hole 2a.

[0023] A set of adjusting washers 4 is provided between the pin cap 3 and the upper surface of the transition trolley 1. The diameter of the pin cap and the adjusting washers 4 is larger than the diameter of the through hole 1a. The pin cap 3 is also connected to a vertical hook 7, and the center of the hook 7 is located on the axis of the pin 2.

[0024] join Figure 2 and Figure 4 The pin hole 2a is a rectangular opening, which is set along the axis of the pin 2. The pin hole 2a is connected to a matching fixing pin 5. The fixing pin 5 includes a connected vertical locking block 51 and a horizontal insert block 52. The horizontal insert block 52 passes through the pin hole 2a and has a fixing pin hole 5a at one end that extends out of the pin hole 2a. The fixing pin hole 5a is connected to a fixing pin shaft 6.

[0025] When manufacturing the shallow spherical center plate fixing device for railway flatcars according to this utility model, the following steps can be followed:

[0026] (1) Take 45# medium carbon steel and add quenching and tempering treatment to increase wear resistance, strength and toughness.

[0027] (2) Make 45# medium carbon steel into a pin style with an upper diameter of 1530mm, a lower diameter of 60mm, a length of 800mm, and a pin cap thickness of 30mm.

[0028] (3) Make a pin hole 2a about 30mm from the bottom of the pin 2. The hole is 60mm long and 20mm wide.

[0029] (4) Weld a hook 7 with a diameter of about 100mm to the top of the made pin 2.

[0030] (5) Cut the 14mm steel plate into an "L" shaped fixing pin 5 with a total length of 130mm, a total width of 70mm, and a width of 60mm at the fixing pin. Make a hole with a diameter of 20mm on the fixing pin 5.

[0031] (6) Use a 10mm steel plate to make two adjusting washers 4, with an inner hole of 70mm and an outer hole of 100mm.

[0032] This invention makes railway flatcar transportation safer and more reliable, reducing maintenance and rescue costs after accidents caused by the displacement of the center plate pin. Before its implementation, based on the frequency of flatcar operation, at least five incidents of center plate displacement or deformation were handled annually, and one traffic accident caused by center plate displacement occurred each year. If such maintenance tasks were calculated at 40,000 yuan per traffic accident, with a labor cost of 200 yuan per person per hour, and requiring five people to work together, and considering the four railway flatcars currently operating at the Nanjing Iron and Steel Plant, the annual cost savings would be approximately: (4*5*200*5+40000)-200*4-8*500=55,200 yuan. Furthermore, the reduced safety risks during maintenance further enhance safety.

[0033] This invention relates to a device that prevents train accidents caused by the displacement of the center pin when railway flatcars pass through curves, reduces railway vehicle maintenance and rescue time, and plays a vital role in ensuring production at front-line manufacturing plants. It also saves maintenance time and improves the efficiency of operators. This invention is applicable to flatcars in all railway systems and industrial enterprises, and has significant social value and application prospects.

[0034] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
