DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0019] like Figure 1-3As shown, a locomotive bogie traction seat includes a seat frame 1, a carrier plate 3 and a traction frame 4. A seat groove 2 is opened in the middle of both sides of the seat frame 1. The two seat grooves 2 are clamped with a carrier plate 3 that can move up and down. The traction frame 4 is fixed at the center of the upper surface of the carrier plate 3. Limiting grooves 5 are also opened on the sides of both ends of the carrier plate 3. Multiple groups of damping mechanisms are arranged in the seat groove 2. The damping mechanism includes a hydraulic oil damping cylinder 6, a hydraulic oil storage cylinder 7, an oil guide pipe 8, a push rod 9, a sealing pressure plate 10, a damping spring 11, a sealing pressure plate 2 12 and a damping spring 2 13. A hydraulic oil damping cylinder 6 is fixed on the inner wall of the bottom of the seat groove 2. The hydraulic oil damping cylinder 6 A hydraulic oil storage cylinder 7 is fixed on one side, and the hydraulic oil pressure-reducing cylinder 6 is connected to the hydraulic oil storage cylinder 7 by an oil guide pipe 8. A push rod 9 which can be pulled up and down is inserted at the top center of the hydraulic oil pressure-reducing cylinder 6. A sealed pressure plate 10 is fixed to the inner end of the push rod 9. A shock-absorbing spring 11 is also arranged in the hydraulic oil pressure-reducing cylinder 6. A sealed pressure plate 12 and a shock-absorbing spring 13 are arranged in the hydraulic oil storage cylinder 7. The overall locomotive bogie traction seat structure is composed of a combination of hydraulic oil and shock-absorbing springs for joint vibration reduction. The hydraulic oil is used as the shock-reducing medium to offset the problem of slow transmission of the spring vibration force, thereby presenting a good shock-reducing effect.

[0020] In this embodiment, the limiting grooves 5 are clamped on the side walls on both sides of the seat groove 2, so as to facilitate the limiting of the carrier plate 3 and ensure its smooth lifting and lowering.

[0021] In this embodiment, the top end of the push rod 9 is fixed to the bottom of the carrier plate 3, and the vibration damping mechanism is firmly fixed between the carrier plate 3 and the seat groove 2, which can exert a good vibration damping effect.

[0022] In this embodiment, the damping spring 11 is located below the sealing pressure plate 10 and is used to cushion the sealing pressure plate 10 and to push it to reset.

[0023] In this embodiment, the second damping spring 13 is located above the second sealing pressure plate 12 and is used to buffer the second sealing pressure plate 12 and press it to reset.

[0024] In this embodiment, the hydraulic oil storage cylinder 7 is also connected to an oil filling pipe 14 for transporting the hydraulic oil back and forth.

[0025] The principles and advantages of this utility model: Figure 2As shown, the hydraulic oil is filled into the hydraulic oil buffer cylinder 6 and the hydraulic oil storage cylinder 7 through the oil filling pipe 14, and then the oil filling pipe 14 is sealed. After the traction seat is installed on the locomotive bogie, the locomotive bogie will press down the carrier plate 3 when it is bumpy, the carrier plate 3 presses down the push rod 9, the push rod 9 presses down the sealing pressure plate 10, and the sealing pressure plate 10 presses down the hydraulic oil in the hydraulic oil buffer cylinder 6. At this time, the damping spring 11 is compressed and shortened, and the hydraulic oil in the hydraulic oil buffer cylinder 6 enters the hydraulic oil storage cylinder 7 through the oil guide pipe 8. At this time, The sealed pressure plate 12 in the hydraulic oil storage cylinder 7 rises, and the shock-absorbing spring 13 is compressed, and the pressure is transmitted with the hydraulic oil as the medium, and vibration is reduced together with the pressure reducing spring, which has a good vibration-absorbing effect. After the vibration is reduced, the shock-absorbing spring 13 uses its own elastic force to stretch and reset, and the hydraulic oil in the hydraulic oil storage cylinder 7 is pushed back into the hydraulic oil pressure-absorbing cylinder 6. The shock-absorbing spring 11 stretches and resets, and the sealed pressure plate 10 and the push rod 9 rise, and the carrier plate 3 also rises, thereby supporting the locomotive bogie to reset.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
