Large-scale equipment on-site heat treatment displacement sliding block device

The invention provides a large-scale equipment on-site heat treatment displacement sliding block device. The large-scale equipment on-site heat treatment displacement sliding block device comprises base plates. The base plates are placed on piers making contact with the ground. Limiting frames shaped like the Chinese character 'tian' are arranged on the base plates. A layer of steel balls are arranged in each limiting frame shaped like the Chinese character 'tian'. Cover plates are arranged on the steel balls. An equipment barrel for heat treatment is placed on the cover plates. The displacement sliding block device is designed to change sliding friction to rolling friction, so that displacement resistance is reduced. The problem of deformation of a lower edge during on-site heat treatmentof large-scale equipment is solved. The construction cost is greatly saved, and the construction period is greatly shortened. Meanwhile, the product quality is improved. 一种大型设备现场热处理位移滑块装置，包括底板，底板放置在与地面接触的支墩上面，底板上放置"田"字型限制框，在
