[0001] The present invention belongs to the technical field of rail transit equipment, and in particular relates to a gangway device with a novel centering mechanism, which can extend the service life of the gangway, reduce maintenance and replacement costs, and improve passenger comfort through reliable connection. Background technology:

[0002] The gangway is an internal passage for passengers to walk freely from one car to another in a vehicle and make passengers feel safe and comfortable. The frame is one of the important components of the gangway, which is used to connect the main body of the gangway with two vehicles or the gangway itself, and plays the role of fixing and supporting the gangway.

[0003] A through-passage in the prior art, a new type of rail transit through-passage structure disclosed in Chinese Patent 202020034611.9, includes an operating lock hook, a connecting plate is fixedly connected to the outer wall of the operating lock hook, a fixed frame is provided on the outer side of the operating lock hook, the operating lock hook is slidably connected to the fixed frame, the connecting plate is slidably connected to the fixed frame, and a spring is sleeved on the outer wall of the operating lock hook, one end of the spring is fixed to the connecting plate, and the other end is fixed to the inner wall of the fixed frame, the inner bottom of the fixed frame is slidably connected to a limiting baffle, one end of the limiting baffle is fixedly connected to a boss plate, and a groove is opened through the boss plate. Chinese Patent No. 201921488848.8 discloses a through passage for connecting two adjacent carriages of a vehicle, comprising: a bellows middle frame, each bellows middle frame being configured to connect adjacent sub-bellows parts to form a bellows; and a pair of floor covering mounting brackets, respectively connected to the bellows middle frame on both sides of the through passage, wherein each of the floor covering mounting brackets comprises: a retaining member, connected to the bellows middle frame and retaining the sub-floor covering parts on both sides to form a floor covering device; and at least one supporting member, one end of each supporting member being connected to the bellows middle frame and the other end being connected to the retaining member; wherein the through passage further comprises a plurality of connecting members, wherein the supporting members are connected to the retaining members through the connecting members. Chinese Patent No. 201911106409.0 discloses a folding canopy type gangway structure for locomotives, comprising two sets of symmetrically installed folding canopy assemblies and ferry plates; the ferry plates are installed under the folding canopy assemblies; one end of the folding canopy assembly is connected to the end face of the carriage, and the other end is in contact with the opposite folding canopy assembly; one end of the ferry plate is connected to the carriage, and the other end is in contact with the opposite ferry plate; the folding canopy assembly comprises a docking plate, an outer spring and a shed cloth assembly; the docking plate is installed at one end of the shed cloth assembly to dock with the opposite folding canopy assembly; foam rubber is pasted on the docking plate to seal the gangway; one end of the outer spring is connected to the carriage, and the other end is connected to the docking plate to lift the folding canopy assembly; the shed cloth assembly is in a compressed state to keep the two folding canopy assemblies in a compressed state at all times. Chinese Patent 202010692231.9 discloses a through passage, comprising: a first side wall, a side wall unlocking mechanism, and a locking rod mechanism; the first side wall is used in the through passage to cover the awning in the through passage, as well as for the inspection of the through passage; the side wall unlocking mechanism is connected to the first side wall for the installation and disassembly of the first side wall in the through passage; the locking rod mechanism is located at the outer end of the through passage, so as to realize the connection between the through passage and an external hanging component or hanging mechanism.During high-speed operation of rail vehicles, the middle frame has a large deadweight and the load change of the ferry installed on the frame easily causes the frame to tilt. In addition, the middle frame will shake back and forth and swing left and right due to its own inertia, and even twist and deflect, which easily causes friction and collision between the middle frame and the connecting parts and other parts, posing a hidden danger to the personal safety of passengers and the safety of vehicle operation. At the same time, it is also easy to cause damage to the gangway itself, such as tearing and bruising. Therefore, a gangway device with a new centering mechanism is developed, taking into account the impact of airflow factors such as double-track operation and entering and exiting tunnels on vehicles, reducing the shaking of the gangway and the skewness of the middle frame, and overcoming the defects such as noise caused by the collision of the fabric frames during operation.
