Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 2 , image 3 As shown, the device embodiment of the present invention mainly includes a suspension mechanism and a driving mechanism. Wherein, the suspension mechanism is used to be movably arranged on the connecting shaft 4 of the horizontal rolling mill. The driving mechanism is arranged on the suspension mechanism, and is used to drive the suspension mechanism to move on the upper connecting shaft 4 of the horizontal rolling mill. The rope sleeve 2 that is used to connect the bottom of the suspension device and the lower connecting shaft 5 of the horizontal rolling mill can be temporarily prepared during application, or can be prepared in advance, so as to cooperate with the suspension mechanism better.

[0034] In this embodiment, another example figure 2 , image 3 As shown, the suspension mechanism i...

Abstract

The invention provides a device and method for rapid replacement of a lower connecting shaft of a horizontal rolling mill. The device comprises suspension mechanisms and driving mechanisms, wherein the suspension mechanisms are used for being movably arranged on an upper connecting shaft of the horizontal rolling mill, and the driving mechanisms are arranged on the suspension mechanisms and are used for driving the suspension mechanisms to move on the upper connecting shaft of the horizontal rolling mill. The analysis result shows that the lower connecting shaft can be replaced rapidly and efficiently, and the purposes that the operation difficulty is reduced, and the labor efficiency is improved are achieved.

Description

technical field [0001] The present invention relates to the field of steel rolling machinery, more precisely, the present invention particularly relates to a device and method for quickly replacing the bottom shaft of a horizontal rolling mill. Background technique [0002] Horizontal rolling mills are widely used in steel rolling equipment. Generally, horizontal rolling mills use two upper and lower universal joint shafts to drive the rolls. Since the universal joint shaft sleeve and the flat head of the roll are in clearance fit, and the rolling force is large, the universal joint shafts need to be regularly Make a replacement. At present, the positional relationship between the upper connecting shaft 4 and the lower connecting shaft 5 of the horizontal rolling mill is as follows: figure 1 As shown, the upper connecting shaft 4 and the lower connecting shaft 5 are all connected between a reducer handle 7 and a connecting shaft sleeve 6, and the upper connecting shaft 4 is...
