Description
Technical Field
The utility model belongs to the technical field of maintenance tools of metro vehicle equipment, and particularly relates to a disassembly and assembly device for a hook rod of a coupler with a gas-liquid buffer.
Background
The appearance structure of the hook rod of the full-automatic coupler with the gas-liquid buffer of the imported (Fu-if) brand used in the existing Guangzhou subway network mainly comprises a hook rod shell, an outer nut at the end part of the shell, a guide rod and the like, and the following structural characteristics of the coupler are as follows, and the device of the utility model also produces the background technology:
for the hook rod of the full-automatic car coupler with the gas-liquid buffer, the impact load after being impacted, which is responsible for the assembly of all components in the hook rod, is very large, so that the locking force of the end nuts, which are responsible for locking the assembly positions of all components in the hook rod, is very large; in addition, from the viewpoint of the safety of the hook rod structure of the hook, the end locking nut of the hook rod is not provided with a nut head which can be positioned by a common dismounting tool, and the appearance of the whole end nut is almost smooth and cylindrical; moreover, the end nut locks the end of the coupler rod shell which has a larger diameter and can ensure that a long guide rod with a certain length of compression track passes through the coupler rod shell, the outer diameter of the guide rod of the coupler rod is not greatly different from that of the coupler rod shell, the whole full-automatic coupler is horizontally hung at the front end of a train, the large-size guide rod and the thin-wall coupler rod shell do not allow the wall thickness of the locking nut with larger outer diameter (shell end) to be too large, so that the risk of influencing the radial deformation force of the guide rod and the shell is avoided under the influence of long-time gravity and vibration after the coupler is loaded, and therefore, the whole end nut is thin and long in wall thickness, the longitudinal length of a smooth cylindrical surface is long, and the end nut with the structure cannot be disassembled if a general or slightly special nut loosening tool is used.
In summary, in the design of the loosening and screwing device of the end nut with the structure, the positioning structure capable of breaking the smooth long cylindrical outer surface of the nut, the application point and the structure capable of screwing or unscrewing the original large locking force are needed, the locking structure capable of ensuring continuous repeated use of the outer surface of the end nut, the thin-wall large outer diameter nut structure, the internal threads of the nut and the external threads of the hook rod shell are also needed, and the long guide pillar with the larger outer diameter extending from the middle of the end nut is also needed to be avoided. In the coupler service manual, the manufacturer clearly indicates that the original special coupler lever dismounting tool provided by the coupler manufacturer needs to be used.
At present, a full-automatic coupler rod with a gas-liquid buffer of an import brand is disassembled or assembled, and a special tool matched with a coupler factory is needed, but so far, the Guangzhou subway does not see the special tool matched with the coupler factory, so that the Guangzhou subway has no capability of independently disassembling the coupler rod with the structure.
