Coiler Reel Removal Method and Load Limiting Device

Abstract

The invention discloses a dismantling method of a coiler drum. The method comprises the steps that S1, a bearing limiting device is moved to the part below the drum, wherein the bearing limiting device comprises a bearing platform and a limiting member which is installed on the bearing platform, and the limiting member is provided with a limiting cavity; the drum is supported by the bearing limiting device, the drum is located in the limiting cavity, and the limiting member can restrict the relative movement of the drum to the bearing limiting device; S2, the drum is dismantled from a coiler body by using a dismantling fixture. The method the advantages that the bearing limiting device is moved to the part below the drum, the drum is directly supported by using the bearing limiting deviceto conveniently take down the drum from the coiler body, compared with a manner in which scaffolds need to be constructed before the drum is hoisted by using a chain hoist, the operation is simpler, the implementation is easy, and therefore the dismantling efficiency of the dismantling method is higher.

Description

technical field [0001] The invention relates to the technical field of coiler maintenance, in particular to a method for disassembling a reel of a coiler and a bearing limiting device thereof. Background technique [0002] At the end of the hot-rolled thin strip steel production line, an undercoiler must be arranged to coil the finished strip. As the core component of the coiler to perform the coiling task, the reel bears more impact loads and radial loads. After a certain period of use, the coil must be replaced to meet the coiling requirements of high-quality hot-rolled steel coils on site. [0003] The reel of the coiler is located in the central area of ​​the coiler. The total length of the reel is nearly 7 meters and the weight is 11.5 tons. Due to its long length and heavy weight, the current method of replacing the coiler drum is as follows: after the equipment stops, set up a scaffolding platform under the drum, and set up a safety net to seal the hole; then use a ...
