Variable-height beam of large ship structure

The invention discloses a variable-height beam of a large ship structure, which comprises a strong cross beam, wherein two bearing mechanisms are symmetrically and fixedly mounted at the bottom end ofthe strong cross beam; a first suspension mechanism is jointly clamped and mounted on the two bearing mechanisms; a single-hole wire clamp is mounted at the top end of the first suspension mechanismin a clamping manner; a double-hole wire clamp is mounted at the top end of the first suspension mechanism in a clamping manner; four supporting rods are symmetrically welded to the upper surface of the first suspension mechanism; a second suspension mechanism is mounted on the two bearing mechanisms in a sliding manner; the second suspension mechanism is erected at the top ends of the four supporting rods; two clamping mechanisms are symmetrically clamped and mounted on the second suspension mechanism; the top ends of the two clamping mechanisms are each provided with a damping mechanism.
