[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by using a liftable ship-shaped anti-sinking plate, when it is moved to the construction site and reaches the designated construction site, the anti-sinking plate can be lowered to be flush with the ground, thereby increasing the contact area between the crane and the ground, thereby preventing the collapse caused by the soft ground at the seaside when the crane is picking up materials and moving. This solves the problem that the existing lifting work platform of the high-pile dock construction is prone to sinking and unstable operation due to the soft ground during operation, and greatly improves the stability of the lifting platform during operation.

[0016] 2. In the present invention, the top reinforcement pulling assembly can increase the stability of the hanging frame when the pipe pile is taken and moved. The rear pulling method can avoid the crane from tilting forward, and the anti-sinking plate can further increase the stability of the crane during operation.

[0017] 3. In the present invention, through the support assembly, when the crane is in operation, the crane body can be reinforced by the fixed cone to prevent the crane body from rotating when the material is moved after being lifted. The linkage and synchronous design of the fixed cone and the anti-sinking plate makes the operation easier and also ensures the stability of the crane during operation.

[0018] 4. In the present invention, the anti-drop rod in the hook assembly can prevent the hanging rope from falling off from the hook body during lifting, thereby preventing the lifting rope from falling off due to excessive shaking of the pipe pile material due to strong wind at the seaside, thereby ensuring the safety of the crane during operation.

10. A method for using a lifting work platform for high-pile wharf construction derived from the lifting work platform for high-pile wharf construction according to any one of claims 1 to 9, characterized in that: The method for using the lifting work platform comprises the following steps: In the step (A), the crane body (1) is moved to a designated construction location and stopped; The step (A1) is to drive the crane body (1) to a designated location at the construction site through the operating room (2); In the step (A2), the servo cylinder (73) is turned on, so that the servo cylinder (73) operates to push the anti-sinking plate (71) downward, and while the anti-sinking plate (71) moves downward, the slide bar (74) is driven to slide inside the limiting sleeve (75) until the bottom surface of the anti-sinking plate (71) abuts against the ground, thereby supporting the crane body (1); In the step (A2), the anti-sinking plate (71) moves downward, while driving the movable plate (812) downward. When the movable plate (812) moves downward, the driven gear (811) is driven to rotate through the teeth (813). When the driven gear (811) rotates, the connecting rod (810) is driven to rotate. When the connecting rod (810) rotates, the second bevel gear (89) is driven to rotate. The second bevel gear (89) can drive the meshing bevel gear (88) to rotate. The first bevel gear (88) drives the threaded sleeve (82) to rotate. Under the action of the thread, the inner screw (83) is driven downward, thereby driving the fixed cone (85) downward through the connecting plate (84). When the connecting plate (84) moves downward, it drives the second slide rod (86) to slide inside the fixed sleeve (87). The fixed cone (85) moves downward and is inserted into the ground, thereby supporting the crane body (1). In the step (B), the lifting rope on the material to be transported is hung on the hook assembly (5), and the transport operation is controlled through the operating room (2); In the step (B1), when hanging, the anti-dropping rod (53) is pressed, so that the anti-dropping rod (53) rotates in the fixing block (54) and compresses the spring (56), so that the anti-dropping rod (53) rotates to the inside of the hook body (51) and opens, and the hanging rope is hung inside the hook body (51), and under the guidance of the positioning groove (52), it abuts and engages inside the positioning groove (52); In the step (B2), after the sling is hooked, the anti-dropping rod (53) is loosened to release the squeezing of the anti-dropping rod (53). At this time, the anti-dropping rod (53) is pushed by the spring (56) to contact the inner wall of the hook body (51) again, so that the hook body (51) can be sealed; In the step (B3), during the transport operation, the operating room (2) controls its own rotation and controls the direction of the hanging frame (3). During adjustment, the hanging frame (3) is pulled and reinforced by the pulling rope (63) and the connecting head (62). When it is necessary to raise or lower the hook assembly (5), the winding machine (65) is opened to allow the winding machine (65) to release or reel in the wire, thereby controlling the lifting and lowering of the hook assembly (5), thereby transporting materials such as pipe piles; After the step (C) is completed, the anti-sinking plate (71) is driven upward by the servo cylinder (73), and the movable plate (812) is driven upward at the same time, thereby driving the threaded sleeve (82) to rotate in the opposite direction through the teeth (813), and the reverse rotation can drive the inner screw (83) to move upward, thereby pulling the fixed cone (85) out of the bottom surface, and the crane body (1) can be moved.
