step 5, adjusting a spring piece (1-1) in the constant-load spring device (1) to a certain distance in advance to ensure that constant tension is synchronously and stably provided, threading the other end of the steel wire rope (4) across a guide wheel (5-1) and a workbench (7) through a V-shaped clamping groove D (7-1) through a steel wire rope clamping block (6-1) and a steel wire rope secondary clamping block (6-2), and respectively clamping the steel wire rope by adopting a welding node mode;
and 6, finally realizing the counterweight balance of the working load through debugging.
