Thick plate line rolling mill stand roller test run device and detection method

Abstract

The invention belongs to the technical field of machinery, and relates to a thick plate line rolling mill stand roller test run device and a detection method, the thick plate line rolling mill stand roller test run device comprises a test run tool platform and a stand roller assembly fixedly installed on the test run tool platform, and the stand roller assembly comprises a stand roller body and bearing seats arranged at the two ends of the stand roller body in a matched mode; and the test run tool platform comprises an installation platform and fixed bases fixed to the two ends of the installation platform respectively, and the fixed bases are higher than the installation platform and fixedly attached to the bottoms of the rack roller assembly bearing seats. The test run tool platform is used for performing test run detection on the rack roller, so that the repair test run acceptance of the rack roller is guaranteed, and the repair quality is improved; and the device can simulate the production working condition to detect the forward and reverse rotation of the rack roller, and detect the conditions of axial movement, abnormal sound, sealing performance, bearing heating and the like, can guarantee the installation size, effectively prolongs the service life of rack roller equipment, reduces the repair cost, and improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a testing device and a detection method for rack rolls of a thick plate rolling mill. Background technique [0002] Due to the short service life of the frame rolls of the thick plate rolling mill, some production accidents have occurred, affecting the production rhythm. However, the repair test of the existing frame rolls generally uses steel wire ropes and cranes to cooperate with the rotating bearing seat for inspection; usually there is no test run device, which cannot meet the production needs. , It is impossible to check whether the bearing has abnormal noise, jamming, whether the axial clearance is adjusted to the ideal value, etc. The existing technology cannot guarantee the acceptance of the repair test run of the rack roll, and the repair cannot be approved. It is urgent to solve the problem of the rack roll test run and improve the repair quality. Contents of the inv...
