Description
Technical Field
The utility model relates to a door technical field especially relates to a pneumatic hatch door structure.
Background
Vehicle doors, which are an important component of light rail and subway vehicles, play an important role in the operation of the vehicles. The quality of door design, manufacture and control directly affects the operation of urban rail vehicles. The inventor finds that the existing subway door is very complicated in structure during the subway taking process, and the bottom of the vehicle is provided with a lock catch to prevent the door from being unfolded under the crowded condition, so that the installation cost of the door is increased.
SUMMERY OF THE UTILITY MODEL
The main objective of the present invention is to provide a pneumatic cabin door structure.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a pneumatic hatch door structure characterized in that: the device comprises a first door plate, a second door plate, a cylinder, a tension spring, a limiting groove guide rail, a linear slide rod, a left chain wheel, a right chain wheel and a door frame; the left chain wheel and the right chain wheel are respectively arranged on two sides of the upper part of the gantry, and conveying chains are wound on the left chain wheel and the right chain wheel; the limiting groove guide rail is arranged at the bottom of the door frame, the bottoms of the first door panel and the second door panel are arranged in the limiting groove guide rail and are in sliding fit with the limiting groove guide rail, the upper part of the first door panel is in sliding fit with the left side of the linear slide rod through a first sliding frame, the two ends of the linear slide rod are transversely fixed at the upper part of the door frame, the upper part of the first sliding frame is fixedly connected with the uppermost conveying chain, the upper part of the second door panel is in sliding fit with the right side of the linear slide rod through a second sliding frame, and the upper part of the second sliding frame is fixedly connected with the lowermost conveying chain; the cylinder is fixed between the transfer chain, the piston rod of cylinder with first carriage is connected, the one end of extension spring with the upper portion of first carriage is connected, the other end of extension spring is fixed on the portal, the upper portion of portal is equipped with the protection casing.
Compared with the prior art, the utility model, this device structure is very simple and practical, and the fault rate is very low, only needs a cylinder, utilizes two parts conveying opposite principle about the conveyer belt, controls opening and shutting of two doors, again because the bottom of two door plants is blocked in the spacing groove guide rail all the time, and upper portion is fixed a position by the linear slide bar, so saved the buckle structure of current door bottom, inside outside extrusion in carriage can effectively be resisted to this structure, and overall cost is very low, the follow-up maintenance of being convenient for.

fig. 2 is a cross-sectional view a-a of fig. 1.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings. As shown in fig. 1-2, a pneumatic cabin door structure comprises a first door panel 1, a second door panel 2, a cylinder 3, a limiting groove guide rail 4, a linear slide rod 5, a left chain wheel 6, a right chain wheel 7, a door frame 8 and a tension spring 9; the left chain wheel and the right chain wheel are respectively arranged on two sides of the upper part of the gantry, and a conveying chain 10 is wound on the left chain wheel and the right chain wheel; the limiting groove guide rail is arranged at the bottom of the door frame, the bottoms of the first door panel and the second door panel are arranged in the limiting groove guide rail and are in sliding fit with the limiting groove guide rail, the upper part of the first door panel is in sliding fit with the left side of the linear slide rod through a first sliding frame 11, the two ends of the linear slide rod are transversely fixed at the upper part of the door frame, the upper part of the first sliding frame is fixedly connected with the uppermost conveying chain, the upper part of the second door panel is in sliding fit with the right side of the linear slide rod through a second sliding frame 12, and the upper part of the second sliding frame is fixedly connected with the lowermost conveying chain; the cylinder is fixed between the transmission chains, and a piston rod of the cylinder is connected with the first sliding frame. One end of the tension spring is connected with the upper portion of the first sliding frame, the other end of the tension spring is fixed on the door frame, and a protective cover 13 is arranged on the upper portion of the door frame.
The working principle is as follows: when needs opened the door, the cylinder drives first carriage and moves left, and first carriage lower part drives first door plant and moves left, realizes the state of opening the door, because the upper portion fixed connection of first carriage and transfer chain, so drive the transfer chain anticlockwise rotation, at this moment, the second door plant that is located the transfer chain lower part will synchronous move right to first door plant and second door plant are opened simultaneously, and when needs were closed, the cylinder was admitted air to opposite direction, closure that can be quick under the effect of extension spring.
The device has the advantages of simple and practical structure, very low failure rate, only one cylinder, control of opening and closing of two doors by utilizing the principle that the upper part and the lower part of the conveyor belt convey oppositely, and effective resistance to outward extrusion inside the carriage due to the fact that the bottoms of the two door plates are always clamped in the limiting groove guide rail and the upper part of the two door plates are positioned by the linear slide rod, and subsequent convenience in maintenance.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
