Embodiment 1

[0018] Such as figure 1 , figure 2 , image 3 As shown, the anti-wind sand pedal of the railway vehicle in this embodiment includes a box-type box body composed of a coaming plate 1 and a sealing plate 2. A pedal 3 is welded in the coaming plate 1. The pedal 3 is a lentil pattern steel plate. The pedal 3 is provided with several An oblong hole for preventing deposition of rainwater and sand; a frame 4 is fixed on the upper edge of the hoarding plate 1, and an L-shaped connecting iron 5 welded to the hoarding plate 1 is provided under the frame 4, and the connecting iron 5 is welded and fixed to the iron floor 6; near the end beam 7- The coaming 1 on the side is welded and fixed to the end beam 7, and the coaming 1 on the side away from the end beam 7 is welded and fixed to the side beam 8; the upper side of the coaming 1 is connected with a flap 9 through a hinge, and the front end of the replica is welded with a threshold 10. The inner side of the door sill 10 has an L-sha...

Abstract

The invention relates to a sand wind preventing pedal of a railway vehicle. The pedal comprises a case type box composed of an enclosure plate and a sealing plate, a pedal body is arranged in the enclosure plate in a welded mode, a frame is fixed to the upper edge of the enclosure plate, an L-shaped connecting iron part welded to the enclosure plate is arranged below the frame and fixedly welded to an iron floor, the side, close to an end beam, of the enclosure plate is fixedly welded to the end beam, the side, away from the end beam, of the enclosure plate is fixedly welded to an edge beam, a turnover plate is connected to the position above the enclosure plate through a hinge, a doorsill is welded to the front end of the turnover plate, an L-shaped groove is formed in the inner side of the doorsill, and the two groove walls of the L-shaped groove are suitable for abutting against a sealing rubber strip on a lower opening of a side door of the vehicle. According to the sand wind preventing pedal of the railway vehicle, the section form of the doorsill is optimized, contact with the side door is improved, and a good sealing effect is achieved; due to the fact that the enclosure plate and the pedal body are of an integrated case type structure, the side outline of the enclosure plate is consistent with the structure of a vehicle body, and the rigidity of the pedal is obviously improved.

Description

technical field [0001] The invention relates to a rail vehicle pedal structure and belongs to the field of car body structure design. Background technique [0002] The purpose of adding pedals to railway passenger cars is to meet the requirements of passengers getting on and off at different platform heights. At the same time, aesthetic factors must be considered to coordinate the structure of the pedals with the entire vehicle. Because the pedal is located under the side door of the vehicle, there is a problem of poor sealing between the pedal threshold and the side door. Therefore, in some countries or regions with large wind and sand, the pedals are required to have the function of preventing the invasion of wind and sand. In addition, the general pedal is a U-shaped structure, which has the problem of insufficient rigidity and severe longitudinal vibration. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome t...
