Description

Technical Field

[0001] The utility model relates to the technical field of bogies, in particular to a molten iron car bogie and car body anti-separation device and a molten iron car. Background Art

[0002] The molten iron car is a special transport vehicle used by metallurgical enterprises to transport molten iron from blast furnaces to converter workshops. It has the characteristics of large molten iron capacity, good thermal insulation performance, energy saving, reduced consumption, improved working environment, and simplified process flow.

[0003] The connection between the iron car frame and the bogie is that the upper center plate on the frame is seated on the lower center plate of the bogie. The upper and lower center plates can rotate relative to each other to ensure that the iron car can pass through the curve smoothly. There is no vertical limit device between the upper and lower center plates, and the control of horizontal freedom is limited by the circumferential vertical edges of the lower center plate. This structure makes it easy for the upper center plate on the iron car frame to fall off the lower center plate, causing the upper center plate of the frame and the lower center plate of the bogie to be misaligned. If it is not discovered and handled in time, it is easy to cause a major accident of the iron car derailment. Utility Model Content

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] This embodiment provides a molten iron car bogie and car body anti-disengagement device, including an upper anti-disengagement device 1 and a lower anti-disengagement device 2.

[0045] like Figure 1 , 2 As shown, the upper anti-disengagement device 1 includes a top plate 11, which is fixedly arranged at the lower part of the frame side beam 41, and a hanging plate 12 is vertically arranged on the lower surface of the top plate 11. A limiting hole 121 is opened on the hanging plate 12, and the limiting hole 121 is rectangular. Two first ribs 13 are fixedly arranged on the hanging plate 12 by welding, and the two first ribs 13 are respectively arranged at both ends of the length direction of the limiting hole 121. By setting the two first ribs 13, the strength and rigidity of the hanging plate 12 can be improved, so that the limiting hole 121 on the hanging plate 12 can be used as a lifting hole to ensure that the frame 4 can be lifted together with the bogie 3.

[0046] like Figure 3 As shown, a welding bevel 122 is provided at the top of the hanging plate 12 , and the welding bevel 122 is used to weld the top of the hanging plate 12 to the top plate 11 , so as to facilitate the welding operation of the hanging plate 12 .

[0047] like Figures 4 to 6 As shown, the lower anti-disengagement device 2 includes a cylinder 21 and a large pin shaft 23. One end of the cylinder 21 is fixedly arranged on the side end of the bogie 3 by welding. A plurality of second ribs 22 are fixedly arranged on the outer wall of the cylinder 21 by welding. The plurality of second ribs 22 are welded and connected to the side end of the bogie 3, which can improve the stability of the connection between the cylinder 21 and the bogie 3 during transportation.

[0048] One end of the large pin 23 is inserted into the cylinder 21, and two coaxial fixing holes are provided on the cylinder wall of the cylinder 21. A circular hole is provided on the large pin 23, and the circular hole is coaxially arranged with the fixing hole. A fixing shaft 24 is inserted in the circular hole and the fixing hole. In this embodiment, the fixing shaft 24 is also a pin, and the fixing shaft 24 can prevent the large pin 23 from axially moving. A cotter pin 25 is inserted at the lower end of the fixing shaft 24, and the cotter pin 25 is a GB / T91-2000 standard part, and the cotter pin 25 can prevent the fixing shaft 24 from being separated from the fixing hole. Through the arrangement of the large pin 23, the fixing shaft 24, and the cotter pin 25, the installation and separation of the frame 4 and the bogie 3 are more convenient.

[0049] like Figure 7 As shown, this embodiment further provides a molten iron car, comprising four of the molten iron car bogies and car body anti-detachment devices, and the four molten iron car bogies and car body anti-detachment devices are arranged in pairs symmetrically.

[0050] like Figures 8 to 11 As shown, the cylinder 21 is arranged perpendicular to the hanging card plate 12, and one end of the large pin 23 passes through the center of the limiting hole 121. The length and width of the limiting hole 121 are both larger than the diameter of the large pin 23. The length of the limiting hole 121 must ensure that the large pin 23 and the limiting hole 121 do not interfere with each other during the rotation of the upper center plate and the lower new plate, and the width of the limiting hole 121 must ensure that when the large pin 23 moves to the top of the limiting hole 121, the upper center plate and the lower center plate will not be separated and misaligned.

[0051] The method for using the anti-separation device between the bogie and the car body of the molten iron car is as follows:

[0052] Installation Instructions:

[0053] The upper anti-disengagement device 1 is welded to the lower part of the frame side beam 41, and the cylinder 21 and the second rib plate 22 of the lower anti-disengagement device 2 are welded to the side end surface of the bogie 3. After installation, the vertical center lines of the upper anti-disengagement device 1 and the lower anti-disengagement device 2 are in the same plane, and the large pin 23 is installed to ensure that the large pin 23 is in the center of the hanging card plate 12, and then the fixed shaft 24 is installed, and finally the cotter pin 25 is installed.

[0054] Disassembly Instructions:

[0055] Take out the cotter pin 25, take out the fixed shaft 24; take out the large pin shaft 23.

[0056] The anti-disengagement device of the molten iron car bogie and the car body can prevent the car frame 4 and the bogie 3 from being misaligned during the operation of the molten iron car, thereby causing the molten iron car to be derailed, and prevent the tank body from scratching the car frame 4 when the steel plant crane raises and lowers the molten iron tank, causing the car frame 4 and the bogie 3 to be misaligned. In addition, when dealing with the molten iron car derailment accident on site, the car body can be lifted together with the bogie 3 to achieve rapid reset. When the molten iron needs to be lifted as a whole for maintenance, it can also be lifted at one time, without the need to lift the car body first, then lift the bogie 3, and then assemble, thereby improving the maintenance efficiency.

[0057] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
