Embodiment 1

[0033] This embodiment discloses a train door that can be turned over to overlap the platform, such as Figure 1-2 As shown, including the upper door, a lower door is also arranged between the upper door and the train floor, and the upper door and the lower door jointly close the compartment; the bottom edge of the lower door is hinged on the train, so that the lower door can rotate outwards and overlap on the platform. Its turning angle can change with the gap distance and the height difference between the train and the platform until it is close to the platform.

[0034] Such as Figure 3-4 As shown, the bottom of the two sides of the lower door is provided with a lower door shaft hole, and the position matching the lower door shaft hole on the train is provided with a train shaft hole, through which the rotating shaft is inserted into the lower door shaft hole and the train shaft hole to realize the lower door shaft hole. The bottom edge of the door is hinged to the train...

Embodiment 2

[0041] Compared with Embodiment 1, this embodiment replaces the drive motor drive system with an electric push rod drive system. Specifically, such as Figure 5-7 As shown, the inner middle part of the lower door (preferably near the bottom position) is provided with an electric push rod hinge support, and the electric push rod is arranged in the middle of both sides of the lower door on the train, and the electric push rod is installed on the electric push rod connecting seat of the train. The driving end of the electric push rod is connected with the hinge support of the electric push rod to drive the lower door to rotate. This connection method can ensure the stability and tightness of the hinge, and the lower door can be freely turned inward and outward through the expansion and contraction of the electric push rod.

[0042] The opening method of the train door based on the above-mentioned reversible overlapping platform: under the closed state of the lower door, the lowe...

Abstract

The invention discloses a train door capable of overturning to overlap with a platform; the train door comprises an upper train door body, a lower train door body is further arranged between the uppertrain door body and a train floor, and the upper train door body and the lower train door body jointly close a carriage. The bottom edge of the lower train door body is hinged to the train, so that the lower train door body can rotate outwards and be overlapped on the platform. The invention further provides a corresponding train door opening and closing method. The invention aims to solve the problem that existing devices designed for gaps between train doors and platforms are not suitable for popularization and application, and provides the train door capable of overturning to overlap on the platforms and the opening and closing method of the train door. According to the train door, the function of covering gaps of the platform is achieved in the mode that the train door is divided to form the lower area, and the lower train door is turned over and connected to the platform in a lap joint mode.

Description

technical field [0001] The invention belongs to the technical field of rail transit train doors. Specifically, it relates to a train door lapped on a platform in an overturning manner, and an opening method and a closing method thereof. Background technique [0002] The floor of the train car is generally 5-10cm higher than the platform. Moreover, in order to ensure the safety of the train during the start and stop process and avoid collision with the platform, a gap of appropriate width will be left between the train and the platform. The existence of this gap will increase the possibility that passengers' small belongings will fall into the track area and their feet will be stuck in the gap. Based on this, it is more necessary to design a device that can be connected between the train compartment and the platform, so as to reduce the risk of passenger accidents and ensure that passengers inside and outside the train can get on and off the train conveniently and safely. ...
