Description

Technical Field

[0001] This utility model relates to the field of hoisting sling technology, and specifically to hoisting slings used in marine engineering construction. Background Technology

[0002] Marine engineering construction is a highly complex and systematic operation carried out in a complex marine environment, encompassing core aspects such as offshore platform construction, submarine pipeline laying, and wind power foundation installation. As a key load-bearing component connecting lifting equipment (such as offshore floating cranes and quay cranes) and the suspended load (such as platform modules, steel pipe piles, and wind turbine towers), rigging directly determines construction safety and efficiency. Rigging refers to equipment used in conjunction with ropes and cables, such as hooks, tensioners, cable clamps, slings, and shackles.

[0003] Chinese utility model patent CN222159528U discloses a hoisting sling for marine engineering construction, which includes "by placing the chain from the blocking block into the hanging ring and placing it on the pressure plate, the pressure sensor on the pressure plate transmits the signal to the controller, the controller controls the motor to drive two electric push rods to extend, thereby driving the limit plate to move inward, clamping the chain and preventing the chain from shaking"; however, it contains circuitry, and the wiring is susceptible to corrosion from rainwater and salt spray, and the control system may also malfunction due to vibration and electromagnetic interference, leading to the chain falling off and increasing the danger of hoisting. Utility Model Content

[0004] The purpose of this invention is to provide hoisting slings for marine engineering construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting sling for marine engineering construction, comprising a connecting block, hooks fixedly connected to the top two sides of the connecting block, a hook ring installed at the bottom of the connecting block by a main bolt, and a limiting component provided on the inner side of the hook ring.

[0006] The limiting assembly includes a first connecting rod and a second connecting rod fixedly connected to both ends of the hook ring. A first fixing block is rotatably connected to the outside of the first connecting rod. A limiting ring is fixedly connected to the top of the first fixing block. A first mounting block is fixedly connected to the lower part of one side of both ends of the limiting ring. A second fixing block is fixedly connected to the outside of the second connecting rod. A second mounting block is fixedly connected to the top of the second fixing block. The first mounting block and the second mounting block are connected by a secondary bolt.

[0007] The beneficial effects of this utility model are as follows: the limiting ring limits the hoisting chain, and the auxiliary bolt can pass through the through hole and enter the second threaded groove hole to install the limiting ring, so that the limiting ring will not move. This effectively limits the chain and prevents the chain from falling off, increasing the safety of hoisting. The whole operation process is easy and convenient, without the need for cumbersome steps, reducing labor and saving time. At the same time, the elastic gasket can reduce friction on the chain and prevent damage to the chain.

[0008] To enable the installation and removal of the hook and loop:

[0009] Further configuration: A first threaded slot is provided on the inner side of the top of the hook.

[0010] By adopting the above technical solution, the main bolt can be threadedly connected to the first threaded slot to install the hook ring for subsequent hoisting work, and the main bolt can be disengaged from the first threaded slot to disassemble the hook ring.

[0011] To reduce wear on the chains:

[0012] Further configuration: The limiting ring is U-shaped, and an elastic gasket is installed on the inner side of the limiting ring.

[0013] By adopting the above technical solution, the hoisting chain can be limited by the limiting ring. At the same time, during the limiting process, the elastic pad can reduce friction on the chain and prevent damage to the chain.

[0014] To enable the installation of the limit ring:

[0015] The design further includes: a through hole at the top center of the first mounting block, and a second threaded slot at one end of the top of the second mounting block.

[0016] By adopting the above technical solution, the auxiliary bolt can pass through the through hole and enter the second threaded slot, thereby installing the limiting ring. This prevents the limiting ring from moving, effectively limiting the chain and preventing it from falling off, thus increasing the safety of hoisting.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0023] Please see Figures 1 to 3 The hoisting sling used in marine engineering construction includes a connecting block 1, with hooks 2 fixedly connected to the top two sides of the connecting block 1, and a hook ring 4 installed at the bottom of the connecting block 1 by a main bolt 3, with a limiting component 5 provided on the inner side of the hook ring 4.

[0024] The limiting component 5 includes a first connecting rod 501 and a second connecting rod 502 fixedly connected to both ends of the hook ring 4. A first fixing block 503 is rotatably connected to the outside of the first connecting rod 501. A limiting ring 504 is fixedly connected to the top of the first fixing block 503. A first mounting block 505 is fixedly connected to the lower part of one side of both ends of the limiting ring 504. A second fixing block 506 is fixedly connected to the outside of the second connecting rod 502. A second mounting block 507 is fixedly connected to the top of the second fixing block 506. The first mounting block 505 and the second mounting block 507 are connected by a secondary bolt 508.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, a first threaded slot is provided on the inner side of the top of the hook 4.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the limiting ring 504 is U-shaped, and an elastic gasket is installed on the inner side of the limiting ring 504.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a through hole is provided at the top center of the first mounting block 505, and a second threaded groove is provided at one end of the top of the second mounting block 507.

[0028] The lifting sling used in marine engineering construction operates as follows:

[0029] First, install the wire rope to the hook 2, and then connect it to the hoisting device. When hoisting equipment, place the chain of the equipment to be hoisted inside the hook ring 4 and inside the limiting ring 504. Then rotate the limiting ring 504 so that the bottom of the first mounting block 505 fits against the bottom of the second mounting block 507. Next, pass the auxiliary bolt 508 through the through hole and into the second threaded slot to install the limiting ring 504. The limiting ring 504 limits the chain and reduces wear on the chain by using elastic washers. Hoisting can then be carried out. When it is necessary to disassemble the hook ring 4, rotate the main bolt 3 to disengage it from the first threaded slot. Then, disassemble the hook ring 4 from the inside of the connecting block 1 to remove it.
