Description

Technical Field

[0001] The present application relates to the technical field of water transport and port engineering, and in particular to a floating dock docking system and an automatic lifting mechanism for its connecting bridge. Background Art

[0002] When building a floating dock, especially a tourist dock, the economic feasibility of the project and the number of tourists need to be considered. A relatively simple and low-cost movable bridge is often used, with the waterside end overlapped on the floating dock and the shoreside end overlapped on the bank slope. When the connecting bridge changes with the water level, it is necessary to manually adjust the overlap position of the movable connecting bridge on the bank slope. At present, the commonly used adjustment scheme is to use a manual hand-pulled hoist gantry lifting mechanism. When the water level changes and the overlapping position and slope of the connecting bridge need to be adjusted, an operator standing on the floating dock pulls the hand-pulled hoist to lift the shoreside end of the connecting bridge, and another operator on the shore pulls the cable of the anchored floating dock to adjust the plane position of the floating dock and the connecting bridge. Then the operator on the floating dock pulls the hand-pulled hoist to lower the shoreside end of the connecting bridge and loosen the wire rope to complete the overlapping position adjustment. In addition, when the water level drops or rises suddenly, the slope of the connecting bridge may not meet the operational safety requirements due to the operator's untimely adjustment, and equipment damage or personal safety problems may occur.

[0003] Therefore, the existing hand chain hoist gantry lifting mechanism requires at least two operators to cooperate with each other and go through multiple cumbersome steps to adjust the overlapping position of the connecting bridge. That is, the existing lifting mechanism has the problems of time-consuming and labor-intensive adjustment and inability to adjust in time. Summary of the invention

[0004] In an embodiment of the present application, a floating dock docking system and an automatic lifting mechanism for its connecting bridge are provided. The automatic lifting mechanism for the connecting bridge can automatically lift the connecting bridge to prevent people from passing when the slope of the connecting bridge does not meet the requirements, and all adjustment operations can be completed by a single person on shore, which has the characteristics of saving time and labor and being able to be adjusted in time.

[0005] According to a first aspect of an embodiment of the present application, there is provided an automatic lifting mechanism for a connecting bridge, wherein the connecting bridge comprises a shore end and a water end which are arranged opposite to each other, wherein the shore end is movably connected to a bank slope, and the water end is movably connected to a floating dock, and wherein the automatic lifting mechanism comprises a gantry, an electric winch, a steel wire rope, an angle detection unit, and a control unit;

[0015] The pull rod is arranged obliquely, with the top end fixedly connected to the top of the corresponding column and the bottom end fixedly installed on the floating dock.

[0016] Preferably, the two columns are arranged along the width direction of the connecting bridge.

[0017] Preferably, the angle detection unit is an angle sensor.

[0018] Preferably, the control unit is a single chip microcomputer, a microcomputer, a microcontroller or a PLC (Programmable Logic Controller).

In the embodiment of the present application, the structure with two electric winches 5 is taken as an example for explanation, but in actual use, the position, quantity and power of the electric winches 5 can be set according to actual conditions; one end of the wire rope 6 is wound on the electric winch 5, and the other end is fixedly connected to the shore end 21 of the connecting bridge 2; the angle detection unit 7 is fixedly installed on the connecting bridge 2, and is used to detect the inclination angle between the connecting bridge 2 and the horizontal plane. A wire rope 6 is arranged on each electric winch 5, and the other end of the wire rope 6 is fixedly connected to the shore end 21 of the connecting bridge 2, so that the wire rope 6 is driven by the electric winch 5 to rotate forward or reverse, so that the shore end 21 of the connecting bridge 2 is raised and lowered by winding and unwinding the wire rope 6; the angle detection unit 7 can be an angle sensor; the control unit 8 is connected to the angle detection unit 7 and the electric winch 5 signal, and controls the rotation of the electric winch 5 according to the inclination angle signal detected by the angle detection unit 7 and the angle threshold pre-stored in the control unit 8. The control unit 8 can be a single chip microcomputer, a microcomputer, a microcontroller or a PLC (Programmable Logic Controller). Figure 1 As shown in the structure, the control unit 8 is connected to the angle detection unit 7 and the electric winch 5 through the control cable 9, the control unit 8 is connected to the angle detection unit 7 through the control cable 9 signal connection, the control unit 8 is connected to the electric winch 5 through the control cable 9 signal connection, the control cable 9 for signal connection between the control unit 8 and the angle detection unit 7 and the electric winch 5 is connected by the same wiring harness, or different wiring harnesses can be used for connection, and can be as follows Figure 1 As shown in the structure, the control cable 9 can be laid underwater, and the control unit 8 can be set on the slope 3.

[0032] The above-mentioned automatic lifting mechanism of the connecting bridge includes a gantry 4 installed on the floating dock 1, an electric winch 5 installed on the gantry 4, a wire rope 6 connected to the electric winch 5 and the connecting bridge 2, an angle detection unit 7 for detecting the inclination angle of the connecting bridge 2, and a control unit 8 for controlling the electric winch 5 according to the detected inclination angle signal; in actual use, the angle detection unit 7 detects the inclination angle between the connecting bridge 2 and the horizontal plane in real time, and the control unit 8 stores the inclination angle threshold of the connecting bridge 2. When the actual inclination angle of the connecting bridge 2 exceeds the inclination angle threshold, the control unit 8 controls the electric winch 5 rotates to raise the bank-side end 21 of the bridge 2, thereby disconnecting the bridge 2 from the bank slope 3, preventing people from passing through, avoiding danger, and preventing the bridge 2 from being tilted too much due to the height change of the floating dock 1 when the water level rises or falls, thereby preventing the occurrence of safety hazards; subsequently, the shore operator can pull the cable of the anchored floating dock 1 to adjust the plane position of the floating dock 1 and the bridge 2, and operate the control unit 8 to rotate the electric winch 5 to lower the bridge 2 and loosen the wire rope 6, so as to overlap the bank-side end 21 of the bridge 2 on the bank slope 3, and complete the overlap position adjustment work. Therefore, the above-mentioned bridge automatic lifting mechanism can automatically lift the bridge 2 when the slope of the bridge 2 does not meet the requirements, and all adjustment operations can be completed by a single person on the shore, which has the characteristics of saving time and effort and being able to adjust in time.

When the connecting bridge 2 is pulled by the steel wire rope 6, tension can be applied to both sides of the shore end 21 at the same time, so that the ends of the connecting bridge 2 are subjected to balanced force, thereby preventing the connecting bridge 2 from being damaged by torsion. Figure 2 As shown in the structure, an electric winch 5 is installed on the top of each column 41, and a steel wire rope 6 is connected between each electric winch 5 and the connecting bridge 2.
