[0002] In the prior art, such as the utility model with application number 201921158310.0, an automatic unhooking trolley is disclosed. In order to solve the problem that in the traditional trolley device, the loading and unloading process is all done manually because the hook is fixed, which is very inefficient and dangerous, a motor is provided to provide sufficient forward and reverse power for the rotation of the hook. A multi-faceted shaft is provided to drive the rotating hook to rotate. A controller is provided to control the forward and reverse movement of the motor.

[0003] The above-mentioned applications still have shortcomings:

[0004] Because the rotating hook is designed in the shape of a hook, it needs to be rotated at a certain angle during the unhooking process so that the hoisted item can be unhooked smoothly. This will change the initial hoisting position of the item and cause the unloading deviation.

[0005] To address this issue, an automatic unhooking trolley was designed. Utility Model Content

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-4As shown, this embodiment provides an automatic unhooking trolley, including a support body 1. A lifting rod 2 is installed at the bottom of the support body 1. A first arc-shaped hook 3 is fixedly installed at the bottom of the lifting rod 2. The opening of the first arc-shaped hook 3 is located at the bottom. A guide groove 4 is provided at one end of the bottom of the first arc-shaped hook 3. A second arc-shaped hook 5 is slidably installed inside the guide groove 4. The first arc-shaped hook 3 and the second arc-shaped hook 5 have the same center. A rotating mechanism is provided on the lifting rod 2 to control the sliding of the second arc-shaped hook 5 inside the guide groove 4.

[0022] Overall working principle: During use, the second arc hook 5 passes through the sling on the hoisted item, and the end of the second arc hook 5 is attached to the bottom end of the first arc hook 3, sealing the opening at the bottom of the first arc hook 3. When it is necessary to unhook, the rotating mechanism is used to control the second arc hook 5 to slide into the guide groove 4 and hide inside the first arc hook 3. During the rotation of the second arc hook 5, the sling slides inside the second arc hook 5, so it will not cause the hoisted item to shift, ensuring the accuracy of the unloading position.

[0023] In this embodiment, the outer sides of the bracket body 1, the hanging rod 2 and the first arc-shaped hook 3 are all coated with anti-rust paint, and the hanging rod 2 is rotatably connected to the bracket body 1.

[0024] Local working principle: The anti-rust paint reduces rust during use, and the rotatable connection between the boom 2 and the support body 1 facilitates adjustment of the angle of the hoisted object.

[0025] In this embodiment, the bottom end of the first arc-shaped hook 3 away from the guide groove 4 and the bottom end of the second arc-shaped hook 5 are both inclined surfaces, and anti-slip textures are provided on the inclined surfaces.

[0026] Local working principle: After the ends of the second arc hook 5 and the first arc hook 3 are attached, the inclined surfaces are attached to each other, and the anti-slip texture increases the frictional resistance, ensuring the connection stability between the second arc hook 5 and the first arc hook 3.

[0027] In this embodiment, the inner side of the bottom end of the second arc hook 5 is provided with an arc chamfer, and the inner side of the second arc hook 5 is provided with a wear-resistant coating.

[0028] Local working principle: The curved chamfer reduces the friction on the sling, while the wear-resistant coating reduces the wear on the second curved hook 5.

[0029] In this embodiment, the rotating mechanism includes a motor 6, a reducer 7, a worm gear 8, a through-hole 9, and a toothed groove 10. The motor 6 is installed on the outside of the boom 2. The reducer 7 is installed at the output end of the motor 6. The worm gear 8 is installed at the output end of the reducer 7. The top of the first arc-shaped hook 3 is provided with a through-hole 9. The top of the outer side of the second arc-shaped hook 5 is provided with a toothed groove 10 that cooperates with the worm gear 8.

[0030] Partial working principle: When unhooking, the starting motor 6 drives the worm 8 to rotate. The worm 8 meshes with the tooth groove 10 at the top of the second arc hook 5, thus controlling the rotation of the second arc hook 5 and retracting it into the guide groove 4. When the second arc hook 5 retracts, it can automatically unhook the hoisted item.

[0031] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
