Description

Technical Field

[0001] The utility model relates to the technical field of port equipment, in particular to a telescopic beam for vacuum anchors. Background Art

[0002] In recent years, the development trend of maritime transportation has been towards high-speed, large-scale, high-transportation speed, high-load capacity, faster ship turnover, mechanized loading and unloading operations at docks, and efficient and safe loading and unloading of goods. With the increase in ship tonnage, it is becoming more and more difficult and time-consuming to moor ships with cables, which has put forward new requirements for the mooring system of offshore ports. Fast mooring and fast unmooring have become the new development trend of mooring systems.

[0003] The traditional mooring method is difficult and time-consuming. A 50,000-ton ship generally requires 12 cables for mooring, which takes about 30 to 40 minutes. As the tonnage of the ship increases, the number of cables increases, the diameter is larger, and the mooring time is longer. Accidents are prone to occur during traditional mooring operations, and there are hundreds of cases of personal injury and death caused by cable operations every year. Figure 1 As shown in the figure, after a ship moored with cables docks at a pier, it is not only subject to the impact of wind, waves and currents, but also to external environmental influences such as tides, pressure drainage, and loading. These unstable external forces cause the ship to move continuously, and the connection between the ship and the pier is unstable, thus reducing the loading efficiency and making it easy for the cable to break. Figure 1 As shown, compared with the automatic mooring method, it occupies a larger berthing space at the dock and reduces the berth utilization rate of the dock.

[0004] Vacuum anchor is a kind of automatic mooring method. Through hydraulic technology, the adsorption force generated by vacuum suction cup is used to replace the cable tension of traditional cable mooring. It can quickly stabilize the ship in the berth, generally complete the mooring operation within 10 to 20 seconds, and ensure that the ship is stably connected to the dock during the docking process, which improves the loading and unloading speed, shortens the docking time of the ship, speeds up the ship turnover, and improves the utilization rate of the dock. Since the suction cup acts on the middle part of the hull, the bow and stern cables of the ship will not occupy the space of the dock, which invisibly increases the use space of the dock; and the cable-free operation can avoid danger to the operators, reduce human errors, and improve safety. It can be seen that compared with the traditional ship cable mooring method, vacuum anchor mooring has the characteristics of safety, reliability, and efficiency, and has broad application prospects. However, the existing vacuum anchors are all fixed structures. In actual use, the angle and position of the vacuum suction cup cannot be adjusted according to the actual situation of the ship, so it cannot offset the ship's heel caused by pressure drainage during loading and unloading of cargo, which poses a safety hazard.

[0010] The first hydraulic cylinder is arranged on the base of the vacuum anchor, and its output end is rotatably connected to the outer telescopic beam; the first hydraulic cylinder adjusts the rotation angle of the telescopic beam according to the information monitored by the angle sensor;

[0011] The output end of the second hydraulic cylinder is connected to the inner telescopic beam to drive the inner telescopic beam to perform telescopic movement along the outer telescopic beam; the second hydraulic cylinder adjusts its movement state according to the information monitored by the position sensor.
