1.制作原因在混凝土预制件制作工地,经常使用运梁台车将大型混凝土预制件运送到施工现场。当运梁台车装载大型混凝土预制件到达施工现场后,为防止车轮沉陷、提高吊装作业稳定性,需要使台车架托盘底部与地面工作台接触,形成稳定支撑。此时需将车轮提升一定高度,使其轮缘最低点高于台车架托盘底部。为此,需要设计制作一种升降转向车轮总成,既能实现运梁台车行走、转向功能,又能保证大型混凝土预制件吊装作业的稳定性,满足施工现场对运梁台车的使用需求。
1. Production reasons In the production of concrete prefabricated parts, often using beam trolley will be transported to the construction site of large concrete prefabricated parts. When the transport trolley loaded large concrete prefabricated parts arrived at the construction site, in order to prevent wheel subsidence and improve the stability of hoisting operations, the bottom of the pallet rack needs to be in contact with the ground workbench to form a stable support. At this point the wheel needs to be raised to a certain height so that the lowest point of the rim is higher than the bottom of the pallet of the pallet. Therefore, it is necessary to design and manufacture a lifting steering wheel assembly, which can not only achieve the traveling and steering functions of the girder, but also ensure the stability of the hoisting operation of the large concrete prefabricated parts and meet the requirements for the use of the girder trolley at the construction site .
