Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting heavy pieces of dock and offshore construction, and specifically relates to a novel shackle latch device. Background Art

[0002] During the lifting process of heavy items, the installation and removal of shackle pins are usually completed by manpower. Since large shackles are generally used in the lifting process of heavy items, the weight of the pins generally reaches several hundred kilograms. Relying solely on manpower to install and remove the pins is very inefficient and there are great safety hazards, as well as the risk of heavy objects falling. Utility Model Content

[0003] The purpose of the utility model is to provide a novel shackle latch device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

In the installation preparation stage, the arched bracket and the gusset plate are first fixed to the shackle body by fastening bolts, and the right side of the connecting plate located on the right side is connected to an extension plate, and the middle part of the upper end of the extension plate is connected to a reinforcement plate, and the reinforcement plate is connected to the arched bracket;

[0006] The bottom of the connecting plate on the left side is symmetrically connected to a first-level auxiliary hanging point front and back, the bottom of the connecting plate on the right side is symmetrically connected to a second-level auxiliary hanging point front and back, the bottom left side of the extended plate is symmetrically connected to a third-level auxiliary hanging point front and back, the bottom right side of the extended plate is symmetrically connected to a fourth-level auxiliary hanging point front and back, and the right end of the reinforcing plate is provided with a fifth-level auxiliary hanging point, and the fifth-level auxiliary hanging point is connected with an auxiliary rope through a tension hoist, the upper end of the shackle body is sleeved on the main lifting rope, and the end of the auxiliary rope away from the fifth-level auxiliary hanging point is connected to the main lifting rope, pull out the shackle safety pin, unscrew the shackle nut, hang the tension hoist on the fourth-level auxiliary hanging point, and connect it to the handle at the right end of the shackle pin shaft through a sling, withdraw the shackle pin shaft through the tension hoist until the left end of the shackle pin shaft is in the circular hole on the right side of the bottom of the shackle body, and pull the tension hoist. The reed is moved from the fourth-level auxiliary hanging point to the second-level auxiliary hanging point or the third-level auxiliary hanging point, and the shackle pin is tightened in the reverse direction to prevent the shackle pin from sliding out of the shackle body during the lifting process. Because the center of gravity of the entire shackle is not at the geometric center of the shackle when the shackle is in the wide-open state, in order to prevent the shackle body from tilting after lifting, an auxiliary rope will be hung between the main lifting rope and the fifth-level auxiliary hanging point, and it will be tightened with a tension hoist. When the shackle body is lifted to the lifting lug position and aligned with the lifting lug hole, the shackle pin can be pulled to the shackle closed state by the tension hoist through the first-level auxiliary hanging point, the second-level auxiliary hanging point and the third-level auxiliary hanging point, and the shackle nut and the shackle safety pin are installed. When the shackle is fully installed and checked in place, the next step of lifting and installation of the heavy parts can be carried out. When the workpiece is installed, repeat the above steps to remove the shackle body from the workpiece.

[0007] A shackle pin is provided inside the bottom end of the shackle main body, a handle is connected to the right end of the shackle pin, and a shackle nut which passes through from top to bottom is connected to the left end of the shackle pin.

[0008] Preferably, the gusset plate is in a U-shaped structure, which facilitates the connection and fixation between the gusset plate and the connecting plate.

[0009] Preferably, the shackle body fits inside the buckle plate, thereby improving the stability of the buckle plate on the outside of the shackle body.

[0010] Preferably, a shackle safety pin is connected to the left end of the shackle pin shaft to block the left end of the shackle pin shaft.

[0011] Preferably, the distance between the upper and lower ends of the shackle safety pin is greater than the diameter of the circular hole in the shackle body through which the shackle pin shaft penetrates, which has a further restrictive effect, making it difficult for the left end of the shackle pin shaft to slide out of the shackle body, thereby improving safety.

[0012] Preferably, a gap is left between the main suspension rope and the bow-shaped bracket to prevent the bow-shaped bracket from contacting the main suspension rope and causing damage to the main suspension rope, thereby ensuring the normal use of the main suspension rope.

[0013] Preferably, a gap is left between the third-level auxiliary hanging point and the gusset plate on the right side to prevent the gusset plate on the right side from affecting the hanging sling of the third-level auxiliary hanging point, thereby ensuring the use effect of the third-level auxiliary hanging point.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: when the utility model is in use, a sling is connected between the first-level auxiliary hanging point, the second-level auxiliary hanging point, the third-level auxiliary hanging point, the fourth-level auxiliary hanging point, the fifth-level auxiliary hanging point and the handle, and the tension hoist is pulled on the sling, that is, in the installation preparation stage, the bow bracket and the buckle plate are first fixed to the shackle body by fastening bolts, the shackle safety pin is pulled out, the shackle nut is unscrewed, the tension hoist is hung on the fourth-level auxiliary hanging point, and connected to the handle at the right end of the shackle pin shaft through the sling, the shackle pin shaft is withdrawn through the tension hoist until the left end of the shackle pin shaft is in the circular hole on the right side of the bottom of the shackle body, the tension hoist is moved from the fourth-level auxiliary hanging point to the second-level auxiliary hanging point or the third-level auxiliary hanging point position, and the shackle pin shaft is tightened in the reverse direction to prevent it from being in the lifting process. The shackle pin slides out of the shackle body because the center of gravity of the entire shackle is not at the geometric center of the shackle when the shackle is wide open. In order to prevent the shackle body from tilting after lifting, an auxiliary rope will be hung between the main lifting rope and the five-level auxiliary hanging point, and the rope will be tightened with a tension hoist. When the shackle body is lifted to the lifting ear position and aligned with the lifting ear hole, the shackle pin can be pulled to the shackle closed state with a tension hoist through the first-level auxiliary hanging point, the second-level auxiliary hanging point and the third-level auxiliary hanging point, and the shackle nut and shackle safety pin can be installed. When the shackle is fully installed and checked in place, the next step of lifting and installing the heavy parts can be carried out. When the workpiece is installed, repeat the above steps to remove the shackle body from the workpiece, which solves the problem of shackle installation and disassembly during the lifting of heavy parts, making related work more efficient and safe.
