Description

Technical Field

[0001] The utility model relates to the field of submarine cables, in particular to an automatic unhooking frame for hanging submarine cable laying interlocking blocks. Background Art

[0002] During the laying of submarine cables, it is difficult to unify the terrain of the laying area of ​​the submarine cables. In some areas, the terrain is complex and the geology is hard, making it difficult to bury the submarine cables for protection. As a result, after the laying of the submarine cables, they are easily affected by ocean currents and rubbed and collided with the terrain, and easily sunk by anchors, making the submarine cables easily damaged, which is not conducive to the long-term use of the submarine cables. Therefore, when laying submarine cables in areas with complex terrain, pads will be deposited in the laying area to change the seabed environment of the submarine cable laying area. In areas with hard geology, concrete blocks will be used to cover the submarine cables after the laying of the submarine cables to achieve the purpose of protecting the submarine cables, so as to ensure the safety of the submarine cables during the laying and use process.

[0003] Traditional sedimentation pads or concrete blocks are mainly installed by manual diving, but this method has high workload on divers and low installation efficiency. During the reciprocating diving process, the divers put a heavy physical strain on the divers. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide an automatic unhooking frame for hanging submarine cable laying interlocking blocks, which can complete the paving of sedimentation pads or concrete blocks while avoiding the manual paving process and improving the paving efficiency.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problems is: an automatic unhooking frame for hanging a submarine cable laying chain block, comprising a hanging frame, wherein two opposite sides of the hanging frame are respectively provided with a unhooking driving rod and a plurality of unhooking components, the unhooking driving rod is connected to the hanging frame along the lateral movement of the hanging frame, and the plurality of unhooking components are arranged along the moving direction of the unhooking driving rod, the unhooking component comprises a hanging rod for hanging a suspension rope and two hanging plates, one end of the hanging rod is connected to the unhooking driving rod, the suspension rope is used to connect the chain block, the chain block is formed by connecting a plurality of deposition pads or a plurality of concrete pressing blocks through a connecting rope, two of the hanging plates are provided with moving holes for the hanging rod to be movably connected to the two hanging plates, a hanging groove for hanging the suspension rope is provided between the two hanging plates, a hanging end of the suspension rope is provided with a hanging ring, and the other end of the hanging rod fixes the hanging end of the suspension rope in the hanging groove by passing through the hanging ring, and when the unhooking driving rod drives the hanging rod away from the hanging groove, the suspension rope is separated from the hanging groove.

[0006] Compared with the prior art, the advantages of the utility model are: first, through the design of multiple sets of unhooking components, the hanging frame can suspend the chain block in multiple directions through the suspension rope to ensure the stability of the suspension of the chain block. When the chain block moves with the hanging frame to the paving area, the movement of the unhooking drive rod drives multiple suspension rods to move at the same time, so that the multiple suspension rods release the suspension of the suspension rope, thereby separating the chain block from the hanging frame and paving it to the submarine cable laying area; the design of the suspension groove can limit the suspension rope in the suspension groove when the suspension rod suspends the suspension rope, thereby avoiding the suspension rope from swinging sharply, thereby ensuring the stability of the suspension rope suspending the chain block, and then in the process of the suspension rod moving, the suspension rope is easy to move with the suspension rod. At this time, the movement of the suspension rope can be avoided by limiting the suspension groove. When the suspension rod is separated from the suspension groove, the suspension rope is separated from the suspension rod, which makes it easier to achieve the purpose of automatic unhooking of the chain block and completing the paving.

[0007] As an improvement of the present invention, the unhooking assembly also includes a limit plate, which is arranged on one side of the two hanging plates along the direction in which the hanging rod is separated from the hanging groove. The limit plate is also provided with a movable hole for the hanging rod to be movably connected. Through the improvement, the design of the limit plate can ensure that the hanging rod is supported by the limit plate and at least one hanging plate, and ensure that the hanging rod is axially movable along the movable hole, thereby ensuring the movement stability of the hanging rod, and the problem of the hanging rod tilting when it is separated from the hanging groove will not occur.

[0008] As an improvement of the utility model, the unhooking drive rod is connected to the hanging rod by an iron chain. Through the improvement, the hanging plate may be deformed after a long period of hanging, or welding deviation may occur during the welding process of the hanging plate, resulting in a deviation in the parallelism between the moving direction of the hanging rod and the moving direction of the unhooking drive rod. If a hard connection is adopted between the unhooking drive rod and the hanging rod, movement interference and jamming will be caused when there is a parallelism deviation between the hanging rod and the unhooking drive rod, which is not conducive to the automatic unhooking of the interlocking block. Therefore, an iron chain connection is adopted. Even if there is a parallelism deviation, the iron chain can still drive the hanging rod to move along the axial direction of the moving hole.

[0009] As an improvement of the present invention, a limit handle is provided on the hanging rod, and the limit handle is arranged between the limit plate and the hanging plate close to the limit plate. When the limit handle is against the limit plate, the other end of the hanging rod is separated from the hanging groove and arranged on the hanging plate close to the limit plate, and the connecting end of the hanging rod and the unhooking drive rod is arranged on the side of the limit plate away from the hanging plate. Through the improvement, firstly, through the design of the limit handle, the hanging rod is prevented from being completely separated from the two hanging plates, thereby ensuring the stability of the repeated use of the unhooking assembly. Secondly, because the unhooking drive rod and the hanging rod are connected by an iron chain, the unhooking drive rod is convenient for driving the hanging rod to detach from the hanging groove. Correspondingly, the unhooking drive rod will not be convenient for driving the hanging rod to insert into the hanging groove in terms of moving distance and moving angle. At this time, the hanging rod can be manually operated by controlling the limit handle to insert into the hanging groove and pass through the hanging ring to complete the suspension locking of the hanging rope.

[0010] As an improvement of the utility model, a limit block is provided at the connecting end of the hanging rod and the unhooking drive rod, and the diameter of the limit block is larger than the diameter of the moving hole. Through the improvement, the hanging rod is prevented from being inserted too deeply into the hanging groove, so that the purpose of releasing can be completed quickly when the suspension is released.

[0011] As an improvement of the utility model, a rope hanging plate is provided on one side of the unhooking component, one end of the rope is fixed on the rope hanging plate, and the other end of the rope is fixed in the hanging groove by the hanging rod after passing through the connecting rope of the chain block. Through the improvement, after the other end of the rope is released from the hanging state by the hanging rod, the rope also releases the suspension effect on the chain block. During the continuous movement of the hanging frame away from the chain block, the rope will follow the movement of the hanging frame due to the fixation with the rope hanging plate, thereby achieving the purpose of recovering the rope, and the rope will not be laid on the seabed after the suspension of the chain block is released.

[0012] As an improvement of the utility model, the side of the suspension frame is provided with a plurality of hanging rings for the unhooking drive rod to be movably connected to the suspension frame, and the suspension frame is also provided with a driving hydraulic cylinder for driving the unhooking drive rod to move. Through the improvement, the movement of the unhooking drive rod can be ensured by the design of the driving hydraulic cylinder, and the design of the plurality of hanging rings can ensure the stability of the movement of the unhooking drive rod.
