Embodiment Construction

[0010] figure 1 , figure 2 It is a specific embodiment of the present invention.

[0011] Such as figure 1 As shown, the device includes a bracket 1, a wheel shaft 2, a wheel 3, a wheel gland 4, and a copper sleeve 5; wherein the wheel 3 is installed as a whole through the copper sleeve 5 and the wheel shaft 2, and the wheels 3 are respectively flat wheels or flat wheels according to the shape of the slideway. The V-shaped wheel ensures the direction of the trolley during its travel.

[0012] Such as figure 2 As shown, push the roller changing trolley into the interior of the archway, determine the distance between the trolleys according to the specific size of the rack rollers, and park the dismantled rack rollers on the roller changing trolley through rewinding and other devices. Then pull out the archway to realize quick roll change.

Abstract

A breast roll changing device belongs to the technical field of steel rolling equipment. The device comprising a support (1), axles (2), wheels (3), glands of the wheels (4), and a copper sleeve (5),wherein the wheels (3) are mounted integrally with the axles (2) by the copper sleeve (5), and the wheels (3) refer to flat wheels or V-shaped wheels according to the shape of a slide way, thereby ensuring the moving direction of a barrow. The breast roll changing device has the advantages that a coordination pressure of a field device during the changing of the breast roll can be well released, the breast roll can be changed safely and quickly with less effort without influencing the examination and repair of other hydraulic systems, and the cost performance is high and the manufacturing is simple and easy.

Description

technical field [0001] The invention belongs to the technical field of steel rolling equipment, and in particular provides a rack roll replacement device, which is suitable for quickly and safely replacing rack rolls of the steel rolling equipment and other similar equipment. Background technique [0002] The rolling mill used by the hot rolling branch of Qiangang Company was designed by SMS company, and the replacement of the rolling mill stand roll was fully considered and designed in the design, and the relevant special replacement tools were produced at the same time. In the process of use, it was found that if the replacement tool designed by SMS is used, the automation system and hydraulic system of the relevant equipment must operate normally, and the rolling mill equipment needs to cooperate, so the automation system and hydraulic system cannot be shut down normally during the maintenance process. There are hidden dangers in maintenance and equipment operation, and m...
