Embodiment 1

[0040] Such as figure 1 , 2 As shown in , 6, a hoisting method of an air spring, a sling is installed on the top of the air spring, and the air spring is hoisted by using the hoisting device to hook the sling; Control the hoisting mechanism of the air spring upper gas spring 27 and the lower auxiliary spring 28, the gas spring control part that can control the upper gas spring 27 and the auxiliary spring control part that can control the lower auxiliary spring 28 are set in this hoisting mechanism, and for hanging The lifting part 21 that transporting device is hooked up; During hoisting, utilize lifting device to hook up lifting part 21 and just can make the upper part air spring 27 of air spring and the lower part auxiliary spring 28 be stressed simultaneously and lift air spring. Because the rubber bag 31 of the air spring 23 of the air spring is connected with the auxiliary spring 28 in a conical surface matching self-sealing form, when usually only the upward force is ap...

Embodiment 2

[0070] Such as Figure 7 As shown, a method for hoisting an air spring is different from Embodiment 1 in that the setting of the gravity conversion component is: making an A-shaped shape with a left sliding surface 25 and a right sliding surface 26 with a narrow top and a wide bottom. Frame 24; Make the upper end of left movable arm 14 and the upper end of right movable arm 15 contact with the left sliding surface 25 and the right sliding surface 26 of A-shaped frame respectively; A-shaped frame 24 is connected with lifting parts 21 in the lifting assembly. When the A-frame 24 is lifted by the lifting part 21, under the gravity of the spreader itself and the gravity of the air spring 27, the upper end of the left swing arm 14 and the upper end of the right swing arm 15 are forced to slide along the left sliding surface of the A-frame 24 respectively. 25 and the right sliding surface 26 slide down, and because the A-frame 24 is narrow at the top and wide at the bottom, the uppe...

Abstract

The invention discloses a method for hoisting an air spring. The method comprises the following steps that 1) a lifting appliance for lifting an upper air pressure spring and a lower auxiliary springof the air spring under stress at the same time is manufactured, namely, the manufacturing process comprises the steps that an air pressure spring control part is manufactured, an auxiliary spring control part connected with the air pressure spring control part is manufactured; and a lifting assembly connected with the auxiliary spring control part is manufactured; 2) the lifting appliance is mounted, namely, the air pressure spring is controlled by the air pressure spring control part, and the auxiliary spring is controlled by the auxiliary spring control part; 3) lifting is carried out, namely, a lifting device is used for hooking a lifting assembly, so that the air pressure spring controlled by the air pressure spring control part and the auxiliary spring controlled by the auxiliary spring control part are simultaneously subjected to upward force, when the upward acting force applied to the air spring by the lifting device through the lifting appliance is larger than the gravity ofthe air spring, and the whole air spring is lifted. The method has the advantages that safe and stable hoisting is achieved, and the operation is extremely simple and convenient.

Description

technical field [0001] The invention relates to a hoisting method of train bogie components, in particular to an air spring hoisting method, and belongs to the technical field of rail transit equipment manufacturing. Background technique [0002] Train air spring is the shock-absorbing part of the secondary suspension of train bogie, which plays the role of supporting the car body, reducing vibration and providing lateral and torsional deformation, so as to ensure the safe operation of the vehicle and the comfort of passengers. With the continuous development of rail transit, the previous large-scale vehicles have gradually entered the advanced maintenance cycle, and the air spring system has also entered the maintenance cycle, which needs to be disassembled and inspected. [0003] The air spring system is mainly composed of an upper gas spring and a lower auxiliary spring. The main body of the gas spring is an inflatable rubber bag, and the top of the rubber bag is a circul...
