Cross shaft dismounting device of universal spindle

Abstract

The invention provides a cross shaft dismounting device of a universal spindle. The spindle is used for a rolling mill, and universal joints are connected to the two ends of the spindle, wherein the universal joints comprise cross shafts and universal joint forks; the device comprises a platform, a first support, second supports and supporting mechanisms, wherein the first support, the second supports and the supporting mechanisms are arranged on the platform, the supporting mechanisms are used for supporting the universal joints; the supporting mechanisms comprise bottom plates, lifting shafts are arranged on the bottom plates, and supporting plates are arranged at the top end of the lifting shafts; the lifting shafts can ascend or descend in a vertical direction so as to adjust a heightof the supporting plates, the angle between the two universal joint forks of the universal joints can be adjusted by adjusting the height of the supporting plates to enable the cross shafts to be detached and maintained. The cross shaft dismounting device of the universal spindle can be conveniently disassembled, the operation difficulty is reduced, the operation steps are simplified, and the safety risk is reduced.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, mainly to the field of maintenance of large-scale universal joint shafts, and in particular to a cross-pack dismounting device for universal joint shafts. Background technique [0002] In metallurgical production, in the H-beam production line, the motor drives the gear seat and the connecting shaft to drive the rolling mill to work. During the rolling of the H-beam, due to vibration, the rolling mill connecting shaft is designed as a universal joint with a certain rotation angle. The cross pack is included in the machine. During use, due to the large load and other reasons, the bearings in the cross pack need to be cleaned and replaced regularly. Due to the large size and tonnage of the shaft of the large rolling mill, it is very difficult to lift and turn over. Therefore, it is very difficult to replace the cross pack. Therefore, there is an urgent need for a cross-pack disassembly device...

[0002] In metallurgical production, in the H-beam production line, the motor drives the gear seat and the connecting shaft to drive the rolling mill to work. During the rolling of the H-beam, due to vibration, the rolling mill connecting shaft is designed as a universal joint with a certain rotation angle. The cross pack is included in the machine. During use, due to the large load and other reasons, the bearings in the cross pack need to be cleaned and replaced regularly. Due to the large size and tonnage of the shaft of the large rolling mill, it is very difficult to lift and turn over. Therefore, it is very difficult to replace the cross pack. Therefore, there is an urgent need for a cross-pack disassembly device for the universal joint shaft. After the shaft is hoisted once, adjust and position on the device to complete the disassembly work of the cross-pack bearing.
