Large-scale thread part assembly device and method

The present invention discloses a large threaded component mounting apparatus and method, belonging to the field of mechanical assembly. The apparatus comprising: means for supporting a first horizontal mounting parts to be assembled, for fixing the first part to be assembled clamp assembly platform for the second column cage coaxially mounted parts to be assembled, mounted on the second parts to be assembled tail bearing assembly, the rolling support assembly cooperating with the cage post, and hoist pole for supporting the trolley and connected to the clip and the mounting plate are mounted on the column cage is rotatably mounted within the support assembly rolling , rolling bearing assembly and the support assembly respectively sling suspended from both ends of the pole, the hoist sling provided between the sling and / or the bearing assembly between the pole and the pole assembly and the rolling support. Avoid a large vertical screw assembly parts, high cost due to the large length of parts to be installed, and there is caused a problem a large security risk.
