They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0017] Reference Figures 1 to 2 A hook device for use with a synchronous chain electric hoist comprises a main frame 1, hook assemblies 2 respectively arranged on both sides of the main frame, and chain hook assemblies 3 respectively arranged on the main frame and placed on the four sides for use with the chain electric hoist;

[0018] In order to improve the overall strength of the entire main frame 1, improve stability and assist in the installation of the hook assembly 2, mounting platform plates 11 are horizontally arranged on both sides of the main frame 1, and reinforcing columns 12 are horizontally arranged at both ends of the main frame 1. The mounting platform plates and reinforcing columns are connected to each other to play a stabilizing role.

[0019] The hook assembly 2 includes linear guide rail modules 21 respectively provided on both sides of the main frame 1, a hook bracket 23 mounted on the linear guide rail module 21 via a slider 22, and a servo motor 24 provided on the mounting platform 11 and used to drive the hook bracket 23 to move along the linear guide rail module 21;

[0020] The driving end of the servo motor 24 is connected to a screw rod 25. The bottom of the hook bracket 23 is provided with a bearing seat 26 threadedly connected to the screw rod. The end of the screw rod 25 is provided with a limit seat 27, and the limit seat is provided on the main frame 1.

[0021] In order to cooperate with clamping products, a hook 28 is provided on the hook bracket 23;

[0022] The servo motor 24 drives the screw 25 to rotate, so that the bearing seat 26 moves along the screw, and at the same time drives the claw bracket 23 to move. At the same time, the linear guide modules 21 at both ends of the claw bracket 23 slide together, and the claws move synchronously to achieve clamping and loosening;

[0023] The chain hook assembly 3 includes a hanging frame 31 that supports the main frame 1 and is welded to the main frame 1, a load-bearing block 32 placed in the hanging frame and set on the main frame 1, and a fixed pin shaft 33 that passes through the hanging frame; the fixed pin shaft is used to cooperate with the chain electric hoist hook installation.

[0024] In this embodiment, the hook of the electric hoist is directly hooked with the fixed pin 33 to achieve fixation, and the entire mechanism is driven to move by the electric hoist. After moving to the corresponding position, the servo motor 24 drives the entire hook bracket 23 to move, thereby driving the hooks on both sides to approach and separate from each other, achieving grasping and releasing, and rapid transportation.

[0025] The benefits of the present invention are that the present technical solution realizes automatic tightening and loosening by arranging hook claw assemblies on both sides of the main frame, and in order to be suitable for practical use with electric hoists, four sets of chain hook assemblies are arranged on the main frame to cooperate with the electric hoist for fixation, and in order to ensure the overall strength and stability of the structure, reinforcing columns and lifting frames and load-bearing blocks installed in conjunction with the main frame are provided.
