Description
Technical Field
[0001] The utility model belongs to the technical field of wrist arm production, in particular to a traditional steel wrist arm pre-assembly platform. Background Art
[0002] In modern high-speed railway systems, steel cantilevers, as an important part of the contact network, are responsible for supporting the contact wires of electrified railways and ensuring the stability and safety of power transmission. These steel cantilevers usually need to be precisely pre-configured to adapt to different railway lines and environmental conditions. The design of steel cantilevers needs to consider mechanical properties, durability and electrical characteristics to withstand long-term environmental erosion and mechanical fatigue. The pre-configuration process includes two basic types: flat cantilevers and inclined cantilevers. Each type has different design specifications and installation requirements depending on the line characteristics and geographical environment.
[0003] Traditional steel arm pre-assembly usually relies on standardized designs and components. However, due to the complexity of various railway environments, standardized components sometimes cannot fully meet the needs of specific lines. In addition, the efficiency and accuracy of manual pre-assembly platforms have also become technical challenges. The low efficiency of pre-assembly is mainly due to the time-consuming manual operation, while the difficulty in ensuring accuracy is due to the errors in manual measurement and position adjustment.
