Title:
PRE-ASSEMBLY TOOL
Document Type and Number:
WIPO Patent Application WO/2024/050986
Kind Code:
A1
Abstract:
A pre-assembly tool, comprising a hoisting tool (1) and a fixing tool (2). The hoisting tool (1) is used for hoisting suspension frame arms (4), and a suspension electromagnet and a guide electromagnet are pre-assembled with the hoisted suspension frame arms (4). The fixing tool (2) is used for fixing a whole pre-assembled from the suspension frame arms (4), the suspension electromagnet and the guide electromagnet, so that the size of the pre-assembled whole is ensured to meet a requirement for mounting with suspension frame cross beams, and during transportation and storage, the pre-assembled whole is also fixed and supported by means of the fixing tool (2), thereby reducing the difficulty in the storage and transportation of the pre-assembled whole. When the electromagnets need to be independently maintained, the fixing tool (2) is connected to the pre-assembled whole, and a forklift drives the pre-assembled whole and the fixing tool to descend. The fixing tool (2) keeps the pre-assembled whole in a vertical state, so that workers can perform independent maintenance on the electromagnets, thereby reducing the difficulty in maintenance.
