Problems solved by technology
[0002] At present, the number of retarder jacks used by various railway bureau group companies is very large, and the daily maintenance tasks of retarder jacks are very heavy. However, the degree of automation of the indoor maintenance of retarder jacks is extremely low, and all items require manual operations by operators, such as the disassembly of retarder jacks, Cleaning, assembly, testing, hydraulic oil replacement and acceptance are all manual operations, resulting in differences in the quality of retarder repairs, resulting in potential safety hazards
In addition, in order to improve the deceleration performance and safety performance of the deceleration jack, the new deceleration jack maintenance standard "Requirements for the Installation, Operation and Maintenance of Railway Vehicle Deceleration Jacks" (Q / CR482-2017) stipulates that the deceleration jack is required to change the hydraulic oil every two years , which means that all the deceleration tops on site must be disassembled, cleaned, and assembled again. installation method

The invention discloses a retarder disassembling and assembling device and method. The disassembling and assembling device comprises a split disassembling and assembling mechanism, a pre-assembling mechanism and an overall disassembling and assembling mechanism, wherein the overall disassembling and assembling mechanism comprises a clamp holder, a first support, a sliding support and a screwing assembly; and the pre-assembling mechanism comprises a second support, a guide rod, a positioning plate and a press-fitting assembly. The disassembling and assembling method comprises the following steps of I, disassembly of a retarder: 101, disassembling an oil cylinder body and a piston rod assembly by using the overall disassembling and assembling mechanism; 102, disassembling the piston rod assembly through the split disassembling and assembling mechanism; and II, assembling of the retarder: 201, assembling the piston rod assembly by using the split disassembling and assembling mechanism; 202, pre-assembling the retarder by using the pre-assembling mechanism; and 203, conducting final assembling of the retarder through the overall disassembling and assembling mechanism. According to the retarder disassembling and assembling device and method, the indoor maintenance level of the retarder can be improved, the labor intensity can be greatly reduced, the maintenance quality of the retarder can be ensured, and the equipment quality problem caused by human factors can be avoided.
