Description

Technical Field

[0001] The technical solution of the present invention is applied to the field of railway transportation, and specifically relates to a semi-automatic wheelchair ferry for subway coaches. Background Art

[0002] With the rapid development of major cities, the popularity of subway vehicles is getting higher and higher, and the traditional way of people's travel has been greatly changed. With the rapid development of subway vehicles, people have realized the convenience of subway vehicles. While meeting the convenience of ordinary people's travel, we must also consider the needs of disabled people and infant vehicles. The subway vehicle wheelchair ferry, as a key component in the interior of subway passenger cars, is a key component for disabled people and infant vehicles to travel. For a long time, many newly built lines in domestic subway vehicles have adopted the same height of the platform and the vehicle floor surface. The gap between the vehicle and the platform is small, and the disabled vehicles and infant vehicles need to be manually lifted to get on the bus, which not only increases manpower, but also cannot meet the needs of driving electric disabled vehicles to get on the bus by themselves. At the same time, in the old lines, the vehicle floor surface is inconsistent with the platform height, and high platforms and low platforms appear during the operation. In this way, disabled vehicles and infant vehicles cannot get on the bus by themselves. It is necessary to design a wheelchair ferry. In the case of high and low platforms, when there are disabled vehicles and infant vehicles on the bus, the wheelchair ferry is opened, and the platform and the floor of the car form a ramp for disabled vehicles and infant vehicles to get on the bus.

[0003] In the past, in railway vehicles, there was a retractable wheelchair board hidden in the floor at the door. When the vehicle arrived at the station, the door was opened and the wheelchair board was automatically extended to cover the gap between the vehicle and the platform. This is suitable for the structure where the vehicle floor and the platform are on the same plane. It cannot meet the requirements in the vehicle operation line with high and low platform conversion. Therefore, in order to optimize the structure of the wheelchair board in subway passenger cars, provide multi-functional services, and efficiently utilize the space in the subway passenger compartment, a safe wheelchair board is urgently needed to meet the differentiated needs of different passengers. Summary of the invention

[0004] The purpose of the present invention is to provide a wheelchair ferry with reasonable structure, simple and stylish, simple operation, high load bearing and light weight. The wheelchair ferry is mainly designed to be operated by a driver or other staff. It has the advantages of simple operation, light weight, and can cover a variable platform height from 184mm below the passenger compartment floor to 43mm above the passenger compartment floor.

[0005] To achieve the above-mentioned purpose, the present invention provides a semi-automatic wheelchair ramp for a subway passenger car, characterized in that: a flip sliding mechanism is connected to the ramp ramp for making the ramp ramp flat or folded and slide into or out of the inner side wall of the vehicle, the flip sliding mechanism comprises a connecting plate, a flip seat, a flip plate, a flip shaft, upper and lower sliding brackets at both ends, and a cylinder, the lower part of the connecting plate is connected to the flip seat, the flip seat is connected to the flip plate, the two ends of the flip shaft are movably mounted on the brackets at both ends, the flip plate is mounted on the flip shaft and can rotate synchronously with the flip shaft and slide left and right on the flip shaft, the end of the flip shaft away from the door passes through the bracket at the end and is connected to one end of the swing arm, and the other end of the swing arm is connected to the piston of the cylinder. The cylinder drives the swing arm to rotate through the piston, the swing arm then drives the flip shaft to rotate, and the flip shaft drives the flip plate to rotate, so as to realize the flat or folding of the ramp ramp; after folding and before flattening, the ramp ramp is slid into or out of the inner side wall of the vehicle by manpower.

[0006] Furthermore, the turning shaft is a circular shaft with two symmetrical C-shaped plates connected thereto, and two upper and lower sliding grooves are formed between the two C-shaped plates.

[0007] Furthermore, a C-shaped groove is processed on the matching surface of the flip plate and the flip shaft to match with the C-shaped plate of the flip shaft sleeve to achieve sliding on the flip shaft and synchronous flipping with the flip shaft.

[0008] Furthermore, it also includes a support plate fixedly connected to the brackets at both ends, and the support plate is slidably matched with the mounting plate connected to the inner wall of the vehicle.

[0009] Furthermore, the connecting plate is a columnar cavity structure to ensure structural strength and bearing strength.

[0010] Furthermore, a ramp board pull strap is provided on the outer side surface of the ramp board to facilitate pulling the ramp board out from the side wall.

[0011] Furthermore, a ramp compensation plate is movably connected under the ramp apron to facilitate adaptation to platforms of different forms.

[0012] The present invention connects the ramp ferry through a sliding flip mechanism. When in use, the ramp ferry is pulled out through the sliding cooperation between the flip plate and the flip shaft, and then the cylinder piston contracts to drive the flip shaft and the flip plate to rotate, thereby driving the connecting plate to make the ramp ferry flat, covering the gap between the vehicle and the platform for passengers to get off; before driving again, pull up the ramp ferry, extend it through the cylinder piston, drive the flip shaft to rotate in the opposite direction, so that the flip plate drives the ramp ferry to be folded, and then slides along the flip shaft and pushes into the side wall of the vehicle body. Through the movement of the sliding flip mechanism, the ramp ferry can adapt to the differentiated needs of different passengers in the vehicle operation line with high and low platform conversion, and at the same time efficiently utilize the subway passenger compartment space. The present invention has a reasonable structure, simple operation, high load bearing and lightweight, and can cover a variable platform height from 184mm below the passenger compartment floor to 43mm above the passenger compartment floor.

[0016] See also Figure 1-Figure 2 The specific implementation mode of the present invention includes a ramp crossing board 1, a flip sliding mechanism 2 connected to the ramp crossing board 1, a support plate 3, and a mounting plate 4. The flip sliding mechanism includes a connecting plate 201, a flip seat 202, a flip plate 203, a flip shaft composed of a circular shaft 204 and a C-shaped plate 205, brackets 206 and 208 at both ends, and a cylinder 210. The lower part of the connecting plate 201 is connected to the flip seat 202, and the flip plate 203 is connected to the flip seat. Both ends of the flip shaft are movably mounted on the brackets 206 and 208 at both ends. The flip plate is mounted on the flip shaft and can rotate synchronously with the flip shaft and slide left and right on the flip shaft. The end of the flip shaft away from the door passes through the bracket 208 at the end and is connected to one end of a swing arm 207. The other end of the swing arm 207 is connected to the piston 209 of the cylinder. The use of the cylinder is mainly to facilitate the size of the operating force. The cylinder 210 drives the swing arm 207 to rotate through the piston 209, and the swing arm 207 further drives the flip shaft to rotate. The flip shaft is connected to two symmetrical C-shaped plates 205 on the outer sleeve of the circular shaft 204, and two upper and lower slide grooves are formed between the two C-shaped plates. The mating surfaces of the flip plate 203 and the C-shaped plate 205 are processed with C-shaped grooves, which cooperate with the C-shaped plates to achieve sliding on the flip shaft and synchronous flipping with the flip shaft, thereby realizing the flattening or folding of the ramp ferry; after folding and before flattening, the ramp ferry is slid into or out of the inner side wall of the vehicle by manpower.

[0017] The brackets 206 and 208 at both ends are fixed on the support plate 3, and the support plate 3 slides up and down with the mounting plate 4 connected to the inner side wall of the vehicle. The bracket 208 is connected to the cylinder frame 211, and the cylinder 210 is connected to the cylinder frame 211. 212 is the slideway of the mounting plate 4. The connecting plate 201 connecting the ramp board and the flip sliding mechanism is a columnar cavity structure to ensure the structural strength and bearing strength.

[0018] Reference Figure 3 A ramp pull strap 101 is provided on the outer side of the ramp board, which is convenient for pulling the ramp board out from the side wall. A ramp compensation plate 102 is movably connected to the bottom of the ramp board through a hinge, which is convenient for adapting to different types of platforms.

[0019] The wheelchair ramp of the present invention is stored in a box inside the inner side wall of the vehicle. When in use, the box is opened, and the ramp ramp is manually pulled out through the ramp drawstring, and then flipped downward. At this time, the ramp ramp is automatically lowered to the platform, ensuring that the lower lip of the ramp ramp is engaged with the guide groove of the door, and then it can be used. The order of retraction is the opposite.
