Vertical roller mill with side shifting roll-changer

Abstract

The invention discloses a vertical mill provided with a sideway roll changing rig. The vertical mill comprises a transmission platform, a power output part and a mill body and also comprises a push roller part for pushing the mill body to move horizontally and a lifting part of universal shaft. The push roller part is arranged at one side of the mill body and a roll changing platform is arranged at the other side of the mill body; the lifting part of the universal shaft is arranged at the upper part of the mill body and is connected with two universal shafts and the upper end of the lifting part of the universal shaft is arranged on the transmission platform; one end of each of two universal shafts is respectively connected with the end parts of a couple of roll systems and the other end of each of two universal shafts is respectively connected with the power output part which is arranged on the transmission platform. The vertical mill has the advantages that replacing the roll refers to moving the mill body provided with roll systems as a whole to the outside of the vertical mill for replacement, no obstacle is attached to the operation space for roll replacement, auxiliary equipment is not required, with convenience and rapidness ensured. The vertical mill has the advantages of simple structure, convenient maintenance and overhaul, low labor intensity, etc.

Description

technical field [0001] What the present invention relates to is vertical rolling mill, what particularly relate to is the vertical rolling mill with side shifting roll changing device. Background technique [0002] The mill body of the vertical roller mill in the prior art is fixed on the foundation plate and cannot be moved, and a roll train including a pair of rolls is arranged in the mill body; the transmission distribution box including the cardan shaft is located above the mill body, including the transmission of the motor. The mechanism is located on the side of the mill body. When replacing the rolls, the rolls can only be pulled out from above the roll train. [0003] The structure of the rolling mill body of the prior art is the same as the rolling mill body structure of the present invention, as image 3 As shown, its structure includes: there are two frame main bodies 83 with a set distance therebetween; on both sides of the two frames 83, press plates 11 are res...

AI Technical Summary

Problems solved by technology

[0004] Rolls are prone to wear during production and must be replaced

The existing technology has the following defects in the replacement of rolls: when replacing the rolls, first loosen the anchor bolts and couplings of the transmission distribution box, separate the distribution box to both sides, and let the space for lifting the roll system from above, Then lift out the whole roll system from above to replace the rolls

This type of structure of the vertical roll mill has resulted in cumbersome roll changing operations and long roll changing time; the spline connection parts need to be disassembled and assembled frequently, and the connecting device is easily damaged, which increases the maintenance amount and the consumption of spare parts and spare parts
