Description

Tipper

technical field

The utility model relates to the general process equipment used in the locomotive processing and assembly process, in particular to a turning machine for turning over large plates such as locomotive top cover, car body side plate and car bottom plate.

Background technique

With the continuous rapid development of my country's railway industry, in order to meet the requirements of "high speed and heavy load" put forward by our country, the requirements for the manufacturing quality and speed of locomotives are also getting higher and higher. In such an era that requires high-speed manufacturing, high production efficiency has naturally become an important pursuit goal of manufacturing units, among which processing speed and assembly speed are important factors to improve production efficiency.

In the process of production and processing, because the inner and outer surfaces of the locomotive roof need to be processed, it needs to be turned over, and sometimes the side panels and bottom panels of the car body also need to be turned over during the processing process. ;In the final assembly process, the locomotive roof needs to be assembled on the top of the car body, but usually because the finished locomotive roof is not necessarily placed with the outer surface facing upwards, it can be lifted directly In the state of assembly, the inner surface of the locomotive roof usually faces upward, so before the locomotive roof is hoisted by the crane for assembly, it is also necessary to turn the locomotive roof 180 degrees so that the outer surface faces upward. In the process of locomotive processing and assembly, the operation process of turning over the locomotive roof is an important process related to the production efficiency and safety of the entire production line. Therefore, during the turning process, it is required to ensure the product safety of the locomotive roof itself In order to adapt to the current trend of high-speed production, it is necessary to take into account the safety of the operator and the rapidity of the turning operation.

However, at present, the operation process of overturning large plates such as the roof of a locomotive is mainly completed by manpower. Because the roof of a locomotive is relatively large, it is very difficult to overturn it. Due to the large size of the flipped workpiece and practical difficulties such as manual flipping, the current flipping operation is not easy to ensure the safety of large-scale plate products such as the locomotive roof cover, which will affect the overall product quality and pass rate of the locomotive, and is also easy to injure The operator cannot guarantee the personal safety of the operator well, and cannot prevent work-related accidents; another very real problem is that the current manual turning operation procedure is difficult to ensure that the turning process can be completed quickly and quickly to meet the requirements of high production efficiency. In short, the current overturning operation of large plates such as locomotive roofs cannot meet the requirements of quickness, flexibility, and safety, which affects the efficiency of locomotive processing and assembly, and then affects production efficiency. Among the prior art, there is a lack of a turning machine that is based on the principles of safety, quickness, convenience, and economical use, can not only improve production efficiency, but also ensure the safety of the operator during use.
