After adjustment, connect the mounting seat and the connecting seat with the first bolt. At this time, the installation of the adjusting column is completed.

[0018] S2: Extend the first mounting brackets on both sides so that the first mounting brackets can move on the outer wall of the connecting column through the second movable groove. Place the two first mounting brackets on the opposite side of the two adjusting columns. After releasing the first mounting brackets, the first spring will retract the first mounting brackets on both sides so that the first mounting brackets can fit tightly against the outer wall of the adjusting column.

[0021] S5: Move the base to the appropriate position using the casters, turn the second handle to connect the screw to the ground support assembly, thereby moving the anti-slip block. Once it is in contact with the ground, it can replace the casters in making contact with the ground.

[0022] Compared with the prior art, the present invention provides a modular boat handling machine frame for pontoon bridges and its assembly method, which has the following beneficial effects:

[0023] 1. The modular boat handling machine frame for pontoon bridges and its assembly method, with its universal casters, facilitates free movement of the entire assembly. The adjustable columns allow for spacing adjustments based on the size of the boat handling machine. The anti-slip blocks provide support when the base is idle, preventing slippage. The height-adjustable support blocks can be adjusted according to usage requirements, thus providing support for the frame body used to load the boat handling machine.

[0024] 2. The assembled boat handling machine frame for pontoon bridges and its assembly method, through the opening of the sliding groove and the second bolt, allows the first mounting frame to move up and down while fixing its position, thereby adjusting the installation height of the frame body. Through the setting of the connecting column and the first spring, the first mounting frame can be retracted and limited, and can also be adapted to the spacing of the two adjusting columns.

[0025] 3. The assembled boat handling machine frame for pontoon bridges and its assembly method, through the damper and protective plate, can provide a certain protective effect on the boat handling machine when it is loaded into the inner cavity of the placement slot. At the same time, the second spring can retract the limit blocks on both sides, thereby limiting the boat handling machine.

When the limiting block (29) is fully inserted into the inner cavity of the placement slot (30), the second spring (28) will drive the two limiting blocks (29) to retract through the movable block (26) to clamp the boat handling machine. At the same time, the damper (32) will have a shock absorption effect on the boat handling machine. S4: Rotate the adjusting rod (33) to move the support block (34), rotate the support block (34) to rotate the movable rod (36), and at this time the movable rod (36) will be threadedly connected to the threaded rod (37) to adjust the height of the support block (34) until the top of the support block (34) can fit against the bottom of the bracket body (23) to provide support for the bracket body (23); S5: Move the base (1) to a suitable position using the caster (3), rotate the second handle (8) to drive the screw (7) to connect with the ground support component (5) by thread, thereby driving the anti-slip block (6) to move. After it is in contact with the ground, it can replace the caster (3) to contact the ground.
