Description

Technical Field

[0001] This utility model relates to the field of twisted king block installation technology, and in particular to an automatic unhooking device for twisted king block installation. Background Technology

[0002] Twisted-edge blocks, commonly used in port hydraulic engineering, are widely applied to the outermost layer of breakwaters to protect the breakwater structure by reducing wave impact. Because they directly withstand the impact of wind and waves and require extremely high stability, the blocks are typically large and significantly heavy, with a single block weighing 40-50 tons. The installation quality of these blocks directly affects the structural safety and durability of the breakwater, thus posing a significant challenge to the installation process.

[0003] Traditional methods for installing kingpin blocks rely heavily on manual tying of steel wire ropes and slings, combined with manual or underwater unhooking operations by divers. When installing kingpin blocks below low water levels, manual unhooking is impossible because the blocks are not above the water surface. Relying on underwater divers not only severely restricts construction efficiency but also poses a significant threat to the safety of divers. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic unhooking device for installing the twisted king block.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic unhooking device for installing a twisted block includes a first plate and further includes:

[0007] The second plate is fixed to the lower side of the first plate;

[0008] Side plate body, the side plate body being fixedly disposed on the bottom side of the second plate body;

[0009] And a movable hook body, which is rotatably connected to the bottom of the second plate body via a pin, and the movable hook body moves against the side plate body;

[0010] The side plate is provided with a limiting component to restrict the unidirectional movement of the movable hook.

[0011] Preferably, a lifting rod is fixed to the outside of the movable hook body, and a lifting ring is provided on the top of both the lifting rod and the first plate body, and a lifting rope is provided on the lifting ring.

[0012] Preferably, the first plate includes an upper plate with a lifting ring installed, a lower plate fixedly connected to the second plate, and a first elastic telescopic rod disposed between the upper plate and the lower plate.

[0013] Preferably, the side plate has a movable groove, and the end of the movable hook is movably connected to the movable groove.

[0014] Preferably, the limiting component includes an elastic telescopic plate fixed to the side plate, a connecting plate fixed to the telescopic end of the elastic telescopic plate, a second elastic telescopic rod fixed to the connecting plate, a limiting block fixed to the telescopic end of the second elastic telescopic rod, a pressing inclined surface that abuts against the movable hook body at the end of the limiting block, and an insertion hole that mates with the limiting block on the movable hook body.

[0015] Preferably, a connecting rope is fixedly provided on the connecting plate, and the end of the connecting rope away from the connecting plate is fixedly connected to the upper plate body.

[0016] Compared with the prior art, this utility model provides an automatic unhooking device for installing toggle blocks, which has the following beneficial effects:

[0017] 1. The automatic unhooking device for the installation of the twisted king block uses a first plate to lift the first plate, causing the movable hook to engage with the twisted king block. The movable hook completes the hooking operation under the gravity of the twisted king block. After the twisted king block is installed, the first plate is released, and the movable hook is lifted to automatically unhook the hook, replacing the manual unhooking method. This reduces operational risks and improves work efficiency.

[0018] 2. The automatic unhooking device for the twisted king block uses two plates that are elastically connected to the first plate. When the lifting rope is pulled up, the first plate buffers the tension of the lifting rope, preventing the lifting rope from being pulled directly and rigidly. This makes the force transmitted to the movable hook and the twisted king block more gradual.

[0019] 3. The automatic unhooking device for the installation of the Twisted King Block, by setting a limit component, can restrict the range of motion of the movable hook in one direction, effectively preventing the movable hook from automatically falling off when the Twisted King Block is installed and lowered, thus ensuring the stability of the hoisting.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] like Figures 1 to 3 As shown, this embodiment proposes an automatic unhooking device for installing a twisted block, including a first plate 1, and further including: a second plate 2, a side plate 3, and a movable hook 4; the second plate 2 is fixedly disposed on the lower side of the first plate 1; the side plate 3 is fixedly disposed on the bottom side of the second plate 2; the movable hook 4 is rotatably connected to the bottom of the second plate 2 via a pin 401, and the movable hook 4 and the side plate 3 move against each other; wherein, the side plate 3 is provided with a limiting component for restricting the unidirectional movement of the movable hook 4;

[0029] Furthermore, a lifting rod 5 is fixedly provided on the outside of the movable hook 4, and a lifting ring 6 is provided on the top of both the lifting rod 5 and the first plate 1, and a lifting rope 7 is provided on the lifting ring 6;

[0030] Specifically, the orientation of the twisted block is adjusted before lifting, with two orientations: a three-point grounding orientation and a one-point-one-rod grounding orientation. During land-based binding, these orientations are alternated during lifting. The block's orientation is randomized during placement, achieved by varying the binding posture. The movable hook 4 hooks onto the binding rope on the twisted block. Then, workers pull the lifting rope 7 on the first plate 1. The lifting rope 7 connected to the movable hook 4 is not under tension. The lifting rope 7 can be wound or released using a winch. When the first plate 1 and the second plate 2 are subjected to upward force, the movable hook 4... Under the influence of gravity, the device is lowered vertically. The movable hook 4 swings towards the side plate 3 with the pin 401 as the center, realizing the lifting function of the movable hook 4 on the twisted block. After the twisted block is lowered and installed, the worker releases the lifting rope 7 on the first plate 1 and pulls the lifting rope 7 on the movable hook 4 upward, so that the movable hook 4 swings upward relative to the second plate 2 and the side plate 3 with the pin 401 as the center. The binding rope on the twisted block automatically detaches from the movable hook 4. This application realizes automatic unhooking operation underwater, replacing the manual unhooking method, which reduces the operation risk and improves the work efficiency.

[0031] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the first plate 1 further includes an upper plate 101 with a lifting ring 6 installed, a lower plate 102 fixedly connected to the second plate 2, and a first elastic telescopic rod 103 disposed between the upper plate 101 and the lower plate 102; the first elastic telescopic rod 103 is existing technology and has a spring inside. By setting the first plate 1 as two plates that are elastically connected, the first plate 1 buffers the pulling force of the lifting rope 7 when the lifting rope 7 is pulled, avoiding the lifting rope 7 from being directly and rigidly pulled, which would cause structural damage. This makes the force finally transmitted to the movable hook 4 and the toggle block more gradual.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the side plate 3 is further provided with a movable groove 301, the end of the movable hook 4 is movably connected in the movable groove 301, and the movable hook 4 is provided with receiving grooves on both sides for accommodating the binding rope on the twisted block.

[0033] Furthermore, the limiting component includes an elastic telescopic plate 8 fixed on the side plate 3. The elastic telescopic plate 8 is provided with an elastic element such as a spring for resetting. A connecting plate 801 is fixed at the telescopic end of the elastic telescopic plate 8. A second elastic telescopic rod 802 is fixed on the connecting plate 801. A limiting block 803 is fixed at the telescopic end of the second elastic telescopic rod 802. The end of the limiting block 803 is provided with a pressing slope that moves against the movable hook 4. The movable hook 4 is provided with an insertion hole that cooperates with the limiting block 803.

[0034] Furthermore, a connecting rope 9 is fixedly provided on the connecting plate 801. The end of the connecting rope 9 away from the connecting plate 801 is fixedly connected to the upper plate 101. The first plate 1, the second plate 2, and the side plate 3 should be provided with guide frames to limit the range of motion of the connecting rope 9. Ball bearings can be provided in the guide frames to contact the connecting rope 9 and reduce the wear of the connecting rope 9. The connecting rope 9 and the lifting rope 7 can be made of steel wire rope.

[0035] Specifically, when the lifting rope 7 on the first plate 1 is pulled, the lower plate 102, due to the weight hooked to its bottom, causes the upper plate 101 to move upward relative to the lower plate 102. The first elastic telescopic rod 103 is stretched, and as the upper plate 101 moves upward, it pulls the connecting rope 9. The connecting rope 9 applies force to the connecting plate 801, causing the connecting plate 801 to move closer to the side plate 3. The elastic telescopic plate 8 is compressed, and at this time, the limiting block 803 is within the movement path of the movable hook 4. As the lifting rope 7 on the first plate 1 continues to be pulled, the movable hook 4 swings towards the side plate 3 around the pin 401 and moves within the movable groove 301. When the movable hook 4 swings, it applies a pushing force to the pressing slope of the limiting block 803. The limiting block 803 avoids the movement of the movable hook 4, and the second elastic telescopic rod 80... 2 is compressed until the movable hook 4 is placed vertically under the pull of the lower T-shaped block. At this time, the limiting block 803 is aligned with the insertion hole on the movable hook 4. The limiting block 803 is reset under the push of the compressed second elastic telescopic rod 802. The limiting block 803 restricts the movable hook 4 from moving away from the side plate 3, effectively preventing the movable hook 4 from automatically falling off when the T-shaped block is installed, ensuring the stability of the hoisting. After the T-shaped block is installed, the lifting rope 7 on the first plate 1 is released, the upper plate 101 is reset relative to the lower plate 102, the first elastic telescopic rod 103 is restored, and the connecting plate 801 is no longer under force. This allows the elastic telescopic plate 8 to drive the second elastic telescopic rod 802 and the limiting block 803 to reset through the connecting plate 801. The limiting block 803 leaves the insertion hole, releasing the restriction on the movable hook 4. At this time, the worker can automatically unhook the movable hook 4 by winding up the lifting rope 7 on the lifting rod 5.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
