Description

Technical Field

[0001] This utility model relates to the field of reloaded coil assembly technology, specifically to an internal tension reloaded coil flipping assembly machine. Background Technology

[0002] Cylindrical superconducting magnets are a common type of superconducting magnet. Their main body consists of a coil and a core tube to support the coil. Circuit boards, temperature control components, sensors, and other accessories need to be assembled around the coil. The overall weight after assembly is usually over one ton. Due to their large size and weight, assembling superconducting magnets presents many difficulties. For example, the coil needs to be placed upright during transportation, but it needs to be laid flat during assembly. However, using steel cables to hoist and rotate the coil not only easily damages or wears down the coil and core tube, but also makes the bundling, hoisting, positioning, and dismantling of the steel cables time-consuming and labor-intensive. Furthermore, the heavy coil is difficult to position, hindering assembly operations. Utility Model Content

The front side of the internally tensioned support arm 4 is provided with a set of variable diameter guide wheels 41, and the back side is provided with two sets of fixed guide wheels 42. The outer edges of the variable diameter guide wheels 41 and the fixed guide wheels 42 are located on the same annular surface. The internally tensioned support arm 4 is also provided with a variable diameter mechanism 43 for driving the variable diameter guide wheels 41 to extend and retract. Before fixing the coil 100, rotate the inner tension support arm 4 to a horizontal position. Use a forklift to align the central hole 110 of the coil core with the inner tension support arm 4 and move it forward, allowing the inner tension support arm 4 to enter the central hole 110. Then, spread the variable diameter guide wheel 41 and fix the coil 100 using the variable diameter guide wheel 41 and the fixed guide wheel 42. Next, rotate the rotating arm 3 to change the upright position of the coil 100 to a flat position to facilitate the assembly of accessories around the coil 100. After assembly, rotate the rotating arm 3 to place the coil 100 upright, retract the variable diameter guide wheel 41, and then use the forklift to lift the coil 100 and move it backward to separate the coil 100 from the inner tension support arm 4.

[0033] In this embodiment, the inner tension support arm 4 is a wedge-shaped column, and two sets of fixed guide wheels 42 are located on the wider back side of the wedge-shaped column to support the coil 100 when it is placed upright. One set of variable diameter guide wheels 41 is telescopically located on the narrower front side of the wedge-shaped column. When opened, it cooperates with the fixed guide wheels 42 to fix the coil 100 and prevent the coil 100 from rotating or shifting circumferentially. After the inner tension support arm 4 is inserted into the coil 100, the coil 100 can move axially along the fixed guide wheels 42. In addition, a limiting block 44 is detachably provided at the end of the inner tension support arm 4 away from the second support arm 32 to prevent the coil 100 from detaching.
