Description

Technical field:

[0001] The present invention belongs to the technical field of rail transit equipment, and in particular relates to a rib-type through-channel ferry device, both ends of which can be quickly unlocked and locked. Background technology:

[0002] The gangway is an internal passage that allows passengers to walk freely from one car to another in a rail transit vehicle and makes passengers feel safe and comfortable. The rib-type gangway is one of the important components of the gangway. The gangway is used for the bottom aisle at the connection between two vehicles or cars, and plays a bearing role for passing passengers and protects the safe passage of passengers. The rib-type gangway structure includes a locking beam component, a connecting beam component, a fixed beam component, a locking device, an aluminum plug-in beam, a nylon plug-in beam and an anti-skid sand sticker, etc., wherein the locking device is fixed on the locking beam component, the anti-skid sand sticker is fixed on the upper surface of the aluminum plug-in beam, the aluminum plug-in beam and the nylon plug-in beam are arranged alternately and are located between the locking beam component and the fixed beam component, and the locking beam component and the fixed beam component are connected by the connecting beam component on both sides through connecting screws to form the gangway as a whole.

[0003] The ribbed ferry currently on the market is an integral structure, which includes seven parts, namely, the locking beam component, the connecting beam component, the fixed beam component, the locking device, the aluminum plug-in beam, the nylon plug-in beam and the anti-skid sand sticker. The locking device is fixed on the locking beam component, the anti-skid sand sticker is fixed on the upper surface of the aluminum plug-in beam, the aluminum plug-in beam and the nylon plug-in beam are arranged alternately and located between the locking beam component and the fixed beam component, the locking beam component and the fixed beam component are connected by the connecting beam components on both sides through connecting screws to form a whole ferry; the unlocking and locking between the ferry and other auxiliary supports are operated by a special key; after the ferry is connected as a whole, it plays a bearing role for passengers and provides convenience for passengers to pass through the adjacent vehicle ends; at the same time, after the ferry is assembled, it is hinged and rotated through the connecting screws at its four corners to realize the swing function of the ferry, meeting the various functional requirements of the ferry under various operating conditions of the vehicle. However, at both ends of the vehicle connected to it, only one end can be quickly unlocked and separated by a locking device, and the other end is fixed by a connecting pin shaft, which cannot be quickly unlocked and separated. When the ferry board is normally maintained and inspected with the vehicle, it can only be unlocked and separated from one end, and then the ferry board can be rotated around the connecting pin shaft end to lift it up, which is easily blocked by other parts in the internal space of the through-passage, making it inconvenient to lift the ferry board. Therefore, a rib-type through-passage ferry board device that can be quickly unlocked and locked at both ends is developed and designed, which has good social and economic benefits. Summary of the invention:

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a rib-type gangway ferry device that can be quickly unlocked and locked at both ends, so that the maintenance of the gangway is more convenient.

[0005] In order to achieve the above-mentioned purpose, the main structure of the rib-type through-channel ferry device involved in the present invention includes a ferry outer frame component and a ferry body component; the ferry outer frame component is provided with a ferry body component, and the interior of the ferry outer frame component is provided with a ferry installation shaft.

[0006] The main structure of the outer frame of the ferry board involved in the present invention comprises a fixing frame, an overlapping protective beam, an external aluminum plug-in beam, an external nylon plug-in beam, fasteners and a ferry board lock shaft fixing block; two mutually parallel fixing frames and two mutually parallel overlapping protective beams are connected end to end to form a frame structure, the inner side of the overlapping protective beam between the fixing frames is provided with an external aluminum plug-in beam and an external nylon plug-in beam, the fixing frame and the overlapping protective beam, the external aluminum plug-in beam and the external nylon plug-in beam are all connected by fasteners, and a ferry board lock shaft fixing block is provided on the fixing frame.

[0007] The main structure of the ferry body involved in the present invention includes side frame beams, inner nylon splicing beams, inner aluminum splicing beams, locking mechanisms, locking shafts, rotating handles and locking compression springs; a plurality of inner nylon splicing beams are arranged between two mutually parallel side frame beams, inner aluminum splicing beams are arranged between the side frame beams and the inner nylon splicing beams and between the inner nylon splicing beams and the inner nylon splicing beams, locking mechanisms are arranged at the ends of the side frame beams, locking shafts are arranged in the locking mechanisms, the locking mechanisms are connected to the rotating handles, locking compression springs are also arranged in the locking mechanisms, and two non-contacting wear-resistant plates are arranged on the surfaces of the inner aluminum splicing beams in odd or even rows.

[0008] The outer frame component of the ferry board involved in the present invention is connected with the ferry board body component through a locking shaft arranged in a locking mechanism.

[0009] The outer aluminum splicing beam and the inner aluminum splicing beam involved in the invention are both bonded with anti-skid sand stickers.

[0010] Compared with the prior art, the present invention has made the following five optimizations: First, the ferry structure is designed from an integral type into two parts that can be quickly separated, namely, the outer frame of the ferry and the body of the ferry. The outer frame of the ferry and the body of the ferry are connected and locked by a quick unlocking device, and the two can be quickly unlocked or locked, and both ends can be quickly unlocked and locked; Second, the unlocking or locking mechanism of the ferry is changed from being set at only one end to being able to be operated at both ends; Third, the special tool key is cancelled during the unlocking or locking operation, and an unlocking handle is set for operation; Fourth, a surface on the aluminum splicing beam is provided with a locking mechanism. Add wear-resistant plates on the surface; Fifth, change the connection method between the ferry board and the other connecting parts of the through-passage from pin connection and locking device connection to connection via the ferry board mounting shafts at the four corners of the ferry board; its structure is simple, and the ferry board body can be quickly disassembled, separated and removed from the ferry board frame, providing a larger space for the inspection and maintenance of the through-passage; when the ferry board body is separated, the interference or restriction of the other parts in the internal space of the windshield is effectively reduced or eliminated, thereby improving the convenience and operability of the ferry board maintenance and inspection, and the ability of the ferry board to pass the working conditions under harsh vehicle conditions, making the application range of the rib-type ferry board wider.
