Novel crane crown block wheel structure with automatic deviation rectifying function

Abstract

The invention discloses a novel crane crown block wheel structure with an automatic deviation rectifying function. The novel crane crown block wheel structure with the automatic deviation rectifying function comprises a crown block wheel installed on a crown block wheel fixing shaft. An axle is sleeved with the portion, located on one side of the crown block wheel, of the crown block wheel fixing shaft. The axle is sequentially sleeved with a bearing, a bearing sleeve and a supporting base from inside to outside. A reset cushion block is arranged between the supporting base and the bearing sleeve. Holes are punched in the two sides of the supporting base. A reset spring is installed in the hole in one side of the supporting base, and one end of a driving shaft is fixed in the hole in the other side of the supporting base. The other end of the driving shaft is connected with a driving device. A plurality of position sensors are arranged on the two sides of the crown block wheel, and all the position sensors are all connected with a programmable logic controller (PLC) simultaneously. The controller controls the driving device which is installed beside the crown block wheel and used for driving the crown block wheel. The controller controls the driving device so as to drive the crown block wheel to deviate. The novel crane crown block wheel structure with the automatic deviation rectifying function is simple and reliable in overall structure and ingenious in design, the problem of severe abrasion caused by deviation of the crown block wheel is effectively solved, the overall manufacturing cost is low, and large-scale application and popularization are facilitated.

Description

technical field [0001] The invention relates to a crown wheel device capable of automatic deviation correction, in particular to a novel crown wheel structure of a crane capable of automatic deviation correction. Background technique [0002] When the crane's crane wheels and rails are installed to a certain precision standard, there will be no severe rail gnawing, but due to various complicated reasons, the crane wheels often have severe friction with the rails, especially when the rails of the steel plant are subjected to high temperature steel billets. The dynamic distribution causes the impact of cold shrinkage and thermal expansion, and the straightness of the rails seriously exceeds the standard, that is, the rails are dynamically curved, and the wheels are replaced frequently, which greatly increases the maintenance cost and downtime of the crane. This problem has aroused many people's research interests, and various methods have been tried, but the results are not sa...

[0002] When the crane's crane wheels and rails are installed to a certain precision standard, there will be no severe rail gnawing, but due to various complicated reasons, the crane wheels often have severe friction with the rails, especially when the rails of the steel plant are subjected to high temperature steel billets. Due to the impact of cold shrinkage and thermal expansion caused by dynamic distribution, the straightness of the rails seriously exceeds the standard, that is, the rails are dynamically curved, and the wheels are replaced frequently, which greatly increases the maintenance cost and downtime of the crane

This problem has aroused the research interest of many people, and various methods have been tried, but the results are not ideal, so there is currently no good solution to this problem
