[0021] As Figure 1 and Figure 2 As shown, a mobile hanging ladder for shipbuilding operations of the present invention includes a hanging rod 1 and a hook 9 provided at the upper end of the hanging rod 1. The hook 9 is hung on the hull wall. A first hanging ladder 6 is suspended on the hanging rod 1. A fixed crossbar 5 is provided at the bottom of the first hanging ladder 6. A movable crossbar 4 is slidably installed at the bottom of the fixed crossbar 5. A second hanging ladder 2 is hung at the bottom of the movable crossbar 4. Hanging ears 3 are respectively provided on both sides of the movable crossbar 4. Sockets are respectively provided at both ends of the hanging rod 1. A draw rod 8 is inserted into each of the sockets. A hanging cable 7 is connected between the adjacent draw rod 8 and the hanging ear 3.

[0022] In this embodiment, a sliding rod 11 is provided at the top of the movable crossbar 4, and a sliding groove is provided at the bottom of the fixed crossbar 5. The sliding rod 11 is slidably installed in the sliding groove. The cross-sectional shapes of the sliding rod 11 and the sliding groove are both "T" shaped.

[0023] Among them, the draw rod 8 is made of a hard metal rod, which is meshed and connected with the internal thread on the inner wall of the socket through a thread. To pull out the draw rod, just rotate the draw rod to meet the requirement of lateral movement.

[0024] Among them, a locking screw is provided on the hook 9 for fixing the hanging rod 1 to the hull to prevent the hanging ladder from shaking.

[0025] In this embodiment, the hanging cable 7 is formed by winding multiple metal wires. Bushings are respectively provided at both ends of the hanging cable 7. A limit nut is respectively provided on the outer side ends of the hanging ear 3 and the pull rod 8. The limit nut is assembled by threaded connection with the hanging ear and the pull rod 8. The bushing is inserted from one end of the hanging ear 3 and the pull rod 8.

[0026] When we need to horizontally move one side, just remove the hanging cable in the opposite direction, as Figure 2 shown. Then slide the movable crossbar out relative to the fixed crossbar, pull out the pull rod. By using the first connection point between the fixed crossbar and the movable crossbar, and the second connection point between the pull rod connected by the hanging cable and the hanging ear, the simultaneous operation of the upper and lower hanging ladders can be achieved.

[0027] The beneficial effects of the present invention are as follows: The present invention can enable the simultaneous use of the staff at the upper and lower ends, and does not affect the construction of other staff after horizontal movement, making the use of the hanging ladder more flexible.
