[0006] Further, the round steel pipe and the horizontal pole are arranged at intervals, and the two connecting blocks and the support are arranged at intervals.

[0007] Further, the center line of the round steel pipe, the center line of the horizontal pole and the center line of the support are located on the same straight line.

[0008] Further, a reinforcing rib is fixed between the horizontal pipe and the vertical pipe of the upper end of the support and between the horizontal pipe and the vertical pipe of the lower end of the support.

[0009] Further, the distance between the two connecting blocks and the center line of the support is consistent.

[0010] The utility model discloses beneficial effect is: the utility model solves the problem that large crossbeam protection cover is easy to interfere with horizontal tow chain support in vertical assembly process, and the problem of adjusting protection cover position consumes a lot of time and manpower cost, through the use of this tool, can realize the simple vertical installation of large vertical lathe crossbeam protection cover, not only installation efficiency is high, but also save time and labour, simple and quick operation.
