Description

Technical Field

[0001] The present invention relates to the field of ship cargo transportation, and particularly to an intelligent and rapid lashing and unlocking device for ship deck cargo. Background Art

[0002] In the field of ship cargo transportation, the safe transportation of deck cargo is of crucial importance. When a ship sails at sea, it will face complex environments such as wind, waves, and jolts. This requires that deck cargo must be fixed by reliable lashing devices to prevent the cargo from shifting or falling, and to ensure the safety of ship navigation and the integrity of the cargo.

[0003] Traditional methods for lashing ship deck cargo mostly rely on manual operations, using ordinary tools such as steel wires and chains for lashing and fixing. This method has many drawbacks. On the one hand, manual lashing is inefficient. During the peak periods of loading and unloading, the lashing and unlocking work of a large amount of cargo is time-consuming and laborious, seriously affecting the operation efficiency of the ship. On the other hand, the accuracy and reliability of manual operations are difficult to guarantee. Problems such as uneven lashing force and insecure fixing often occur. In severe sea conditions, the cargo is prone to loosening or even falling off, leading to safety accidents. In addition, after long-term use of traditional lashing tools, the components are severely worn, and repairs and replacements are frequent, increasing the operating costs. With the development of the ship transportation industry towards large-scale and high-efficiency, higher requirements are put forward for the intelligence, rapidity, and safety of deck cargo lashing devices. There is an urgent need for a new type of device to solve the problems in the existing technology and improve the safety and efficiency of ship cargo transportation. Summary of the Invention

[0033] The usage state of the present invention is as follows: The present invention has a reasonable and simple structure, low production cost, and is easy to install. During the process of transporting goods on the ship deck, when using the intelligent and rapid lashing and unlocking device for ship deck goods, the fixed housing 1 is installed and fixed at a designated position on the ship deck to ensure its stability. If it is necessary to release the steel wire rope 6, start the winding and unwinding motor 325 in the winding and unwinding device 3. The left output shaft of the winding and unwinding motor 325 drives the worm 324 to rotate. The worm 324 meshes with the worm wheel 322 for transmission, thereby driving the connecting shaft 323 and the drum 2 to rotate, and the drum 2 releases the steel wire rope 6. If manual operation is required, the hand wheel 33 can be rotated. The hand wheel 33 drives the right shaft end of the winding and unwinding motor 325 to rotate, and also rotates the drum 2 through the transmission mechanism 32 to wind and unwind the steel wire rope 6. After the steel wire rope 6 is released to an appropriate length, the released steel wire rope 6 is connected to the fixed point of the goods, and then the card slot head 5 is inserted into the card hole 45. Here, start the locking drive device 423 (servo motor or stepping motor) in the clamping device 4. The output shaft of the locking drive device 423 drives the double-headed screw 421 to rotate. Since the external threads on the left and right sides of the double-headed screw 421 have opposite helix directions, the two movable blocks 422 move left and right along the double-headed screw 421 in the chute 424, driving the card slot device 44 connected to the top of the movable block 422 to move towards the middle. The connecting block 443 slides in the guide hole 444 of the guide hole seat 441, and the card slot seat 446 moves with the connecting block 443. When the movable block 422 is located in the center of the chute 424, it is convenient for the card slot head 5 to be directly inserted into the card hole 45 and then be clamped by the card slot 447 inside the card slot seat 446 outside the card slot head 5, thus meeting the need for rapid fixation. Here, the spring 445 plays a role in buffering and assisting in clamping. When long-term fixation is required, start the locking drive device 423 to drive the guide hole seat 441 to press tightly against the card slot seat 446. When it is necessary to tighten the steel wire rope 6, start the winding and unwinding motor 325 in the winding and unwinding device 3. The left output shaft of the winding and unwinding motor 325 drives the worm 324 to rotate. The worm 324 meshes with the worm wheel 322 for transmission, thereby driving the connecting shaft 323 and the drum 2 to rotate, and the drum 2 tightens the steel wire rope 6, thereby improving the bundling effect. When rapid unlocking is required, first start the winding and unwinding motor 325 in the winding and unwinding device 3. The left output shaft of the winding and unwinding motor 325 drives the worm 324 to rotate. The worm 324 meshes with the worm wheel 322 for transmission, thereby driving the connecting shaft 323 and the drum 2 to rotate, and the drum 2 releases the steel wire rope 6. Then start the locking drive device 423 to rotate in the reverse direction. The double-headed screw 421 rotates in the reverse direction, and the two movable blocks 422 drive the card slot device 44 to move towards both sides. The card slot seat 446 is separated from the card slot head 5, and then the steel wire rope 6 can be separated from the fixed point of the goods to complete the unlocking.
