Description

Technical Field

[0001] The present application relates to the field of railway passenger cars, and in particular to a panel flipping device for railway passenger cars. Background Art

[0002] In the field of conventional railway passenger cars, especially those running in cold regions, the cold-proof performance of the end pass area has always been the focus of the industry. Due to the insufficient sealing between the flap device of existing vehicles and the surrounding structure and the thermal insulation performance of the flap device itself, the flap is prone to poor opening and closing or even stuck in the low temperature environment in winter, which has caused long-term troubles to the crew and industry engineering and technical personnel.

[0003] The railway passenger car flap device is an important component of the railway passenger car. It is usually located near the carriage door and connected to the stairs. When the carriage door is opened, the flap can be opened to provide passengers with a passage to the stairs so that they can get off the train smoothly. The main purpose of the flap device is to effectively seal the carriage when the carriage door is closed, preventing air, noise, dust, etc. outside the carriage from entering the interior of the carriage from the staircase entrance, ensuring a comfortable and safe environment inside the carriage.

[0004] There are many types of flap devices for conventional railway passenger cars, but for vehicles with hinged side doors, the flap devices are mainly divided into single-layer flaps and double-layer flaps. There is a significant structural problem with these flap devices, that is, there is a lack of internal heating devices. The traditional flap device is only a closed cavity structure filled with cold-proof materials, and there is no heating element such as a heating blanket or heating wire.

[0005] Since the lower part and the facade of the flap are directly exposed to the outside of the vehicle and in direct contact with the outside air, when the vehicle is running in a cold region with low ambient temperature, the difference in room temperature inside and outside the vehicle and the good thermal conductivity of the metal material make it easy for condensation to form liquid and ice on the flap surface. Especially when the vehicle arrives at a low platform station, the flap cannot be opened and closed smoothly due to ice, resulting in vehicle delays and other malfunctions, which seriously affects the normal operation of the railway system in the cold region. Utility Model Content

[0006] The purpose of this application is to provide a railway passenger car flap device that can improve the cold-proof performance of the flap device, improve its opening and closing performance in low temperature environments in winter, and provide crew members and engineering and technical personnel with a more reliable and convenient operating experience.

[0029] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2As shown, the present embodiment provides a railway passenger car flap device, which includes a flap assembly 1, a frame assembly 2 and a rotating shaft assembly 3. The flap assembly 1 is the main part of the flap device, and is composed of a flap body 11 and a heating device 12. The flap body 11 is made of metal or composite materials, and has sufficient strength and rigidity to withstand the trampling and impact of passengers when getting on and off the car. The heating device 12 is arranged in the flap body 11, and is used to heat the flap body 11 to prevent it and the frame assembly 2 from freezing in a low temperature environment. In the present embodiment, the heating device 12 is specifically an electric heating tape, which is arranged along the interior of the flap body 11 and is connected to the power supply through a power cord.

[0031] The frame assembly 2 is used to support and fix the flap assembly 1, and its structure is firm and stable. The shaft assembly 3 is used to control the opening and closing of the flap, and it can be manually operated, or it can be electrically or pneumatically driven.

[0032] like Figure 2 As shown, in this embodiment, the shaft assembly 3 includes a rotating shaft 31, a rotating shaft seat 32 and a first connecting arm 33. The rotating shaft 31 is installed at the bottom of the frame assembly 2 through the rotating shaft seat 32, and one end of the first connecting arm 33 is connected to the rotating shaft 31, and the other end is connected to the flap body 11, so as to realize the rotation of the flap.

[0033] like Figure 4 As shown, in order to further improve the cold-proof performance of the flap device, this embodiment further provides a cold-proof device 13 on the heating device 12. The cold-proof device 13 is a heat-insulating layer wrapped around the outside of the heating device 12, and is made of a material with high heat-insulating performance, such as polystyrene foam. The provision of the heat-insulating layer effectively reduces heat loss and improves the heating efficiency of the heating device 12.

[0034] like Figure 3 As shown, in addition, a threshold 14 is provided on the surface of the flap body 11 to facilitate passengers to get on and off the vehicle. A handrail 15 and a flap lock 16 are provided on the lower surface of the flap body 11. The handrail 15 provides support for passengers, and the flap lock 16 is used to lock the flap to prevent it from accidentally opening.

[0035] The specific wiring method of the heating device 12 is to add a set of single-return arm shafts 17 with nylon hose connectors to serve as the power line lead interface 18 of the heating device 12 inside the flap body 11.

[0036] In this embodiment, the heating device 12 is an electric heating tape or a heating blanket or a heating pipe, which is arranged along the inside of the flap body 11 and connected to the power supply through a power line. The cold-proof device 13 is polystyrene foam or rock wool or glass wool, which is tightly wrapped around the outside of the heating blanket to form a thermal insulation layer.

[0037] like Figure 1As shown, in addition, in this embodiment, a flap sealing strip 4 and a frame sealing strip 5 are provided on the contact surface between the flap body 11 and the frame assembly 2. The bottom of the flap sealing strip 4 and the frame sealing strip 5 are both rubber parts 41, and the top is a rubber sponge part 42. This design enables the flap to fit tightly with the frame when closed, effectively preventing air, noise and dust outside the compartment from entering the interior of the compartment through the gap.

[0038] like Figure 5 As shown, in the present embodiment, the shaft assembly 3 includes, in addition to the rotating shaft 31, the rotating shaft seat 32 and the first connecting arm 33, a spring reset device 6 is added. The spring reset device 6 is arranged on one side of the bottom of the frame assembly 2. When the flap body 11 is unlocked, the rotating shaft 31 of the flap body 11 will open upwards due to the tensioning force of the spring reset device 6, thereby realizing the automatic opening function of the flap.
