Description

Technical Field

[0001] The invention relates to a rail vehicle door system, and in particular to a turnover pedal device suitable for rail vehicles. Background Art

[0002] Due to the gap between rail vehicles and platforms, in order to avoid accidents when people get on and off the vehicle, rail vehicles are now often equipped with sliding pedal devices, which are extended when the vehicle enters the station to make up for the gap and improve safety. However, some shortcomings have been found in actual use: 1. The pedal surface height of the existing sliding pedal device is fixed, and it cannot adapt when the platform ground height changes; 2. The extension distance of the existing sliding pedal device is short, and it cannot make up for the entire gap when the distance between the platform and the vehicle is large; 3. The existing sliding pedal device is difficult to be completely flush with the platform ground, which affects the smooth getting on and off of vehicles such as wheelchairs.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The flip pedal device suitable for rail vehicles of the present invention includes a mounting frame 6, two symmetrical load-bearing guide rails 7 are arranged on the left and right of the mounting frame 6, a pedal trolley 8 is arranged on the load-bearing guide rail 7, the pedal trolley 8 is connected to the driving structure 5 through a scissors-type structure 4, and the scissors-type structure 4 is connected to two linear guide rails 11; the pedal trolley 8 is connected to the movable pedal 2, and a limiting slider 9, a damping block 12, a flip roller 13 and a load-bearing roller 14 are arranged on the pedal trolley 8.

[0020] The scissor structure 4 of the present invention is a scissor structure in which metal rods are cross-arranged. The end points of the scissor structure 4 are respectively connected to the pedal trolley 8 and two linear guide rails 11. The limit slider 9 is connected to the torsion spring 10. A curved structure is provided in the bearing guide rail 7, which cooperates with the flip roller 13 on the pedal trolley 8 to provide guidance for the flipping action of the pedal trolley 8. The mounting frame 6 is provided with a threshold structure 1 and a locking mechanism 3. The mounting frame 6 is arranged on the door system of the rail vehicle.

[0021] The present invention is suitable for the flip pedal device of rail vehicles. Each part is installed with the mounting frame 6 as the main body. There are two bearing guide rails 7 that are symmetrically distributed on the left and right and are respectively arranged in the mounting frame 6. The scissor structure 4 connects the driving structure 5 and the pedal trolley 8, and transmits the power of the driving structure 5 to the pedal trolley 8. The movable end of the scissor structure 4 uses a linear guide rail 11 to limit the displacement direction to ensure smooth movement. The pedal trolley 8 and the movable pedal 2 are directly connected and move synchronously. When the flip pedal device is working, the scissor structure 4 is extended, and the driving pedal trolley 8 and the movable pedal 2 extend out of the mounting frame 6. The pedal trolley 8 itself moves in the bearing guide rail 7 by means of the bearing roller 14. A limited slider 9 is arranged on the pedal trolley 8 to avoid premature flipping and provide support during the working process. A damping block 12 is arranged on the pedal trolley 8, and the damping block 12 can be adjusted to reduce the movement impact of the pedal trolley 8, so that the pedal trolley 8 moves more smoothly. The bearing guide rail 7 has a curved structure, which cooperates with the flip roller 13 on the pedal trolley 8 to provide guidance for the flipping action of the pedal trolley 8, avoiding the impact of the flipping process on the movable pedal 2. When the movable pedal 2 is extended, the threshold structure 1 will open with it. The threshold structure 1 is a split structure. In the non-working state, the threshold structure 1 is reset to the initial position by the torsion spring 10. In the working state, the threshold structure 1 and the movable pedal 2 are fitted by the torsion spring 10. The threshold structure 1 can make up the gap between the movable pedal 2 and the vehicle body, and prevent dirt from entering the internal structure. After the movable pedal 2 is extended, the end will contact the platform ground to form a ramp, and the ramp angle changes adaptively with the distance between the ground and the vehicle. When the work is finished, the drive structure 5 works to shorten the scissor structure 4 and drive the movable pedal 2 to retract. The locking mechanism 3 in the non-working state will lock the pedal trolley 8 to prevent the pedal trolley 8 from starting unexpectedly due to vehicle vibration and other reasons.

[0022] The present invention provides a flip pedal device that can adapt to changes in platform height and distance between the vehicle body and the platform, and can form a ramp in the working state to facilitate wheelchairs and other vehicles to get on and off. It can adapt to various working conditions and improve the safety of people getting on and off the vehicle. Compared with the commonly used translation pedal device on the market, this flip pedal device has stronger platform adaptability, and the ramp structure is more friendly to disabled people in wheelchairs and passengers carrying heavy luggage, etc., reducing the burden of getting on and off the vehicle.
