[0036] like Figure 3 As shown, in one embodiment, the single hook 11 further includes a hook body 112 connected to the hook mouth 111 , a hook handle 113 connected to the hook body 112 , and the hook handle 113 is connected to the driving assembly 2 .
[0037] Through the above technical solution, the hook body and hook handle are designed on the single hook, and the hook handle is connected to the driving assembly, so that the hook mouth can stably grab and lift the pipe pile. The structural design of the hook body and hook handle provides stronger grabbing force and ensures the safety and reliability of operation.
[0038] In one embodiment, the unfolding direction of the two hook openings 111 on the single hook 11 is 70-80°.
[0039] Through the above technical solution, the two hooks on the single hook are designed to have an expansion angle of 70-80°, which improves the gripping stability of the pipe pile. This design allows the hook to better adapt to the diameter change of the pipe pile, reduces the possibility of slipping, and improves the safety of the operation.
[0040] Specifically, the hook mouth is made of wear-resistant material, such as hard alloy, to improve its durability. The hook mouth is designed to be serrated or grooved to increase the friction with the pipe pile and prevent slipping.
[0041] In one embodiment, the driving assembly 2 includes a cylinder 21 ; an output end of the cylinder 21 is connected to the hook handle 113 .
[0042] Through the above technical solution, the cylinder is used as the core part of the driving component, and the output end of the cylinder is connected to the hook handle, thereby achieving precise control of the single hook.
[0043] Specifically, the lightness of the cylinder reduces the weight of the equipment and improves the flexibility and efficiency of operation. The output end of the cylinder adopts a ball joint, which provides multi-angle rotation capability and enhances the flexibility of operation.

[0045] Through the above technical solution, the cylinder is set in the cylinder box and fixed on the first hanger. At the same time, the angle between the first hanger and the second hanger is designed to be 60-90°, which achieves stable support and protection for the cylinder, improves the stability and durability of the device, and facilitates the maintenance and replacement of the cylinder.
[0046] In one embodiment, the included angle between the first hanger 31 and the second hanger 32 is 60-90°.
[0047] Through the above technical solution, the angle between the first hanger and the second hanger is 60-90°, which optimizes the spatial layout of the hanger assembly, improves the stability of the device and the flexibility of operation, and enables the hanger assembly to be adjusted according to operational requirements to adapt to pipe piles of different sizes and shapes.
[0048] In one embodiment, a portion of the hook body 112 close to the hook handle 113 is provided with a through hole 114 , through which the single hook 11 can be detachably fixed to the gas phase box 22 .
[0049] Through the above technical solution, a perforation is set in the part of the hook body close to the hook handle, and the perforation is used to realize the detachable fixation of the single hook, which improves the maintenance convenience and adaptability of the device. Therefore, the worn single hook can be quickly replaced, reducing downtime and improving work efficiency.
[0050] In one embodiment, a reinforcing plate 51 is further included, one end of the reinforcing plate 51 is disposed on the first hanger 31 , and the other end of the reinforcing plate 51 is fixed on the moving component 4 .
[0051] Through the above-mentioned technical solution, a reinforcement plate is arranged on the first hanger and one end of it is fixed to the moving assembly, thereby enhancing the structural strength and stability of the hanger assembly. Therefore, the setting of the reinforcement plate provides an additional support point, making the device more stable when lifting heavy objects and reducing the risk of deformation and damage.
[0052] Specifically, the reinforcement plate is made of high-strength material, such as steel plate or aluminum alloy plate, to improve its bearing capacity; the reinforcement plate is connected to the hanger and the moving component by welding and bolting to ensure the stability of the connection.
[0053] In one embodiment, a connecting hole 33 is provided on the second hanger 32 , and the connecting hole 33 is connected to the moving component 4 .
[0054] Through the above technical solution, a connecting hole is provided on the second hanger, and the connecting hole is connected to the moving assembly, thereby realizing rapid positioning and movement of the hook device.
[0055] Specifically, the mobile assembly can use a crane and a pulley commonly used in the prior art to achieve the lifting and lowering, forward and backward or left and right movement of the mobile assembly, thereby driving the grab hook device to move.
[0056] In addition, this application provides Figure 4 The shown grappling hook system comprises the grappling hook device and a moving component.
[0057] Specifically, the grab hook system realizes the automatic grabbing and lifting of pipe piles by adopting the existing integrated control system.

[0059] Initial position preparation: Before the work starts, the hook device is in the initial position, and the hook assembly, drive assembly and hanger assembly have been properly installed and fixed. The single hook of the hook assembly is connected to the cylinder box through the perforation on the hook body to ensure the stable positioning of the single hook.
[0060] Deployment and positioning of the single hook: The operator issues a command using the existing control system, and the cylinder in the drive assembly starts to work, pushing the hook handle to deploy the single hook. The two hooks on the single hook are adjusted to a deployment angle of 70-80° as needed to accommodate pipe piles of different diameters.
[0061] Grabbing pipe piles: When the single hook reaches the top of the pipe pile, the operator controls the cylinder output end to make the hook mouth accurately align and grab the pipe pile. The special design of the hook mouth, such as serration or groove, increases the friction with the pipe pile and ensures the stability of the grabbing process.
[0062] Lifting and moving the pile: Once the pile is successfully grabbed, the cylinder continues to provide power to ensure that the hook hooks the pile; the hook hooks the pile, and the entire grab hook device is lifted and moved through the moving assembly connected to the reinforcement plate. The reinforcement plate design enhances the structural strength of the hanger, making it more stable during movement.
[0063] Placing pipe piles: After the moving assembly reaches the predetermined position, the pipe piles are placed at the designated position; the operator controls the cylinder to work in reverse to open the hook mouth and release the pipe piles.
