Background
The air spring of the train is a damping component of the secondary suspension of the train bogie, and plays roles of supporting a train body, reducing vibration and providing transverse and torsional deformation, thereby ensuring the running safety of the train and the riding comfort of passengers. With the continuous development of rail transit, a large batch of vehicles gradually enter a high-grade maintenance period, and an air spring system also enters a maintenance period, so that the air spring system needs to be disassembled and inspected.
The air spring system mainly comprises an air pressure spring at the upper part and an auxiliary spring at the lower part, the main body of the air pressure spring is a rubber bag capable of being inflated, and the top of the rubber bag is a circular upper cover plate. The main damping body of the auxiliary spring is made of rubber and is the heaviest part in the air spring, and the upper part of the auxiliary spring is connected with the rubber bag of the air compression spring in a conical surface self-sealing mode.

The existing hoisting method is implemented by extending a threaded hoisting tool from an air inlet in the center of an upper cover plate to be matched with a threaded hole part in the air spring (the part is connected with an auxiliary spring or directly arranged on the auxiliary spring), so that the safety is better, but the hoisting tool is only suitable for the air spring with the air inlet in the center of the upper cover plate.
For the air inlet of the upper cover plate which is not in the middle, the existing hoisting method is to hoist the product by hooking a hoisting tool with a plurality of claws on the edge of the upper cover plate (or a retaining ring) of the air pressure spring of the air spring, and the hoisting tool is suitable for all air springs. However, because the connection between the rubber bag of the air pressure spring of the air spring and the auxiliary spring is in a conical surface matching self-sealing form, when upward force is only applied to the air pressure spring, the heavy auxiliary spring is easy to fall off from the connection part of the rubber bag of the air pressure spring, so that the product is damaged, casualties can be caused in serious cases, and great potential safety hazards exist in the practical use process.
Through search, the application number is CN201010225418.4, and the patent number is the air spring for the vehicle and the installation method of the hanger thereof.

Because the connection between the rubber bag 31 and the auxiliary spring 28 of the air spring 23 of the air spring is in a conical surface matching self-sealing mode, when upward force is usually applied to the air spring 23, the heavy auxiliary spring 28 is easy to fall off from the connection part of the air spring rubber bag 31, so that the product is damaged, casualties can be caused in serious cases, and great potential safety hazards exist in actual use. The method can completely avoid the problems and realize safe and stable hoisting.
As shown in fig. 1 to 6, a gas pressure spring control member capable of controlling the upper gas pressure spring 27 is provided, namely, a disc-shaped member 1 which only needs to firmly hook an upper cover plate 30 of the gas pressure spring and a hook member 2 arranged at the edge of the lower bottom surface of the disc-shaped member 1 are provided; 2-4 radial mounting grooves 7 are formed in the edge area of the lower bottom surface of the disc-shaped component 1 at equal arc length intervals, fastening components 8 are arranged on the mounting grooves 7, the hook component 2 and the fastening components 8 are mounted in the radial mounting grooves 7 in a matched mode, and the fixing position of the hook component 2 in the mounting grooves is adjusted in the radial mode according to the diameter of the upper cover plate 30; an elastic reset piece is arranged in the hook part 2, so that the hook part automatically restores to the position where the edge of the upper cover plate can be hooked and keeps the state where the edge of the upper cover plate can be hooked.
Specifically, the method comprises the following steps: preferably, the air pressure spring control member is made of a disc-shaped member 1 and a hook member 2 which only need to control the edge of the upper cover plate 30 of the air pressure spring 27, and in this embodiment, the hook member has a hook 3, a rotating shaft 4 and a socket 5; 2-4 hook members 2 are mounted on the lower bottom surface near the edge of the disc-shaped member 1 at equal arc length intervals.

An elastic restoring member, such as a torsion spring 6, is provided in the hooking member 2 to automatically restore the hooking member 2 to a position where it can hook the edge of the upper cover 30 and maintain a state where it can hook the edge of the upper cover 30. Therefore, the lifting process of the air compression spring 27 can be prevented, and meanwhile, the air compression spring 27 is controlled to swing along the horizontal direction
As shown in fig. 5 and 6, an elastic member 9 is provided inside the lower bottom edge of the disc-shaped member 1 where the hook member 2 is attached, and the elastic member 9 is compressed when the hook member hooks the edge of the upper cover 30.

The method can enable the hook part 2 to hook the upper cover plate 30 tightly, can adapt to the upper cover plates 30 with different thicknesses, and can remarkably increase the friction force between the upper cover plate and the disc-shaped part 1 in the horizontal direction so as to increase the control force of the disc-shaped part 1 on the air pressure spring in the horizontal direction.
As shown in fig. 1, 2 and 6, the auxiliary spring control member for controlling the lower auxiliary spring 28 is a clamping member for clamping the clamping groove 29 on the base of the auxiliary spring 28, and is a lever mechanism comprising a left lever and a right lever; two supports which are symmetrical left and right and are provided with rotating shafts are arranged on the disc-shaped component 1, and the middle parts of the left lever and the right lever are respectively arranged on the rotating shafts of the two supports; a left movable arm 14 is arranged above the left lever support, a left clamping arm 10 is arranged below the support, a right movable arm 15 is arranged above the right lever support, and a right clamping arm 11 is arranged below the support.

Since some of the clamping grooves 29 on the outer peripheral surface of the base of the auxiliary spring 28 are not deep or even completely absent in practical applications, a strong clamping force of the clamping member is required to clamp the base of the auxiliary spring 28. Converting gravity into a clamping force, the clamping member clamps the base of the auxiliary spring 28 more tightly during hoisting.
