Embodiment Construction
[0010] Such as figure 2 As shown, a buffer device for the balance lever of the hoisting mechanism of a nuclear power plant crane is composed of a balance lever (1), a support (2), a left steel wire rope (6), and a right steel wire rope (4). The middle of the balance lever (1) Installed on the support (2), the left wire rope (6) and the right wire rope (4) are symmetrically installed on both sides of the balance lever (1) through the collar (3), and the two ends of the balance lever (1) They are respectively connected with the pistons of the left oil cylinder (10) and the right oil cylinder (8), and the left oil cylinder (10) and the right oil cylinder (8) are connected to each other with the hydraulic system (7) through the oil pipe (9).
[0011] Since the left oil cylinder (10) and the right oil cylinder (8) are directly connected with the balance lever (1), when the right wire rope (4) fails, the right oil cylinder (8) immediately rises slowly, and the left oil cylinder (10...
