[0026] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other. The following will detail this application with reference to the drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiment of this application with reference to the drawings in the embodiment of this application. Obviously, the described embodiments are only part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0029] Such as Figures 1 to 8As shown in the figure, this embodiment provides an automatic weight loading device, which includes a cantilever crane 1, a ground rail 2, a weight frame 3 and a mobile trolley 4. The cantilever crane 1 is fixed on the ground. The mobile trolley 4 moves back and forth on the ground rail 2. Generally, at least two weight frames 3 are provided. One side outside the ground rail 2 is used to place the weights to be lifted, and the other weight frame 3 is arranged at the middle position of the ground rail 2 for positioning the weights and facilitating the extraction by the mobile trolley 4. A first magnetic material sucking device 11 is arranged on the cantilever crane 1. A lifting mechanism 41 is installed at the front end of the mobile trolley 4, and a second magnetic material sucking device 42 is arranged on the lifting mechanism 41. The first magnetic material sucking device 11 on the cantilever crane 1 sucks the weights and then places them on the weight frame 3 to complete the weight positioning. The mobile trolley 4 moves in front of the weight frame 3 and sucks the weights through the second magnetic material sucking device 42, and moves the weights into the car. This reduces the manual labor intensity, improves the production efficiency and reduces the cost.

[0030] As an alternative embodiment, anti-falling hook components 43 are arranged at both ends of the lifting mechanism 41. The anti-falling hook components 43 are located on both sides of the lifting mechanism 41 and are used to clamp the weights. The anti-falling hook components 43 play an insurance role. Although the second magnetic material sucking device 42 can extract the weights, there is a safety hazard of weight falling when the second magnetic material sucking device 42 loses power or malfunctions. After the second magnetic material sucking device 42 starts to suck, the anti-falling hook components 43 are simultaneously activated to clamp and hook the weights. Before the second magnetic material sucking device 42 abandons sucking the weights, the anti-falling hook components 43 will automatically open to complete the action of placing the weights.

[0031] As an alternative embodiment, the anti-falling hook component 43 includes an electromagnet 431, a locking hook 432 and a spring 433. One end of the spring 433 is connected to both sides of the locking hook 432, and the other end of the spring 433 is connected to the lifting mechanism 41. The electromagnet 431 pushes the locking hook 432 to move back and forth. The locking hook 432 is used to lock the weights to prevent them from falling. During use, the electromagnet 431 retracts the locking hook 432, and under the pulling force of the spring, the locking hook 432 moves inward to buckle the weights. When the electromagnet 431 pushes the locking hook 432, the locking hook 432 moves outward to abandon buckling the weights. This structure is convenient to install and simple in structure.

[0032] As an alternative embodiment, the lifting mechanism 41 includes a vertical track 411 provided on the mobile trolley 4, a slider 412 provided on the vertical track 411, and a connecting bracket 413 mounted on the slider 412. The slider 412 moves up and down on the vertical track 411. The second magnetic material suction device 42 is provided at the bottom position of the connecting bracket 413. A screw 414 is provided at the middle position of the vertical track 411. A moving block 415 that moves up and down is provided on the screw 414. Rotation of the screw 414 drives the moving block 415 to move up and down, thereby driving the connecting bracket 413. The moving block 415 is fixed to the connecting bracket 413. The end of the screw 414 is connected to a first driving motor 416, and the first driving motor 416 drives the screw 414 to rotate.

[0033] As an alternative embodiment, a second driving motor 417 is provided inside the mobile trolley 4. A gear 418 is mounted on the second driving motor 417. A rack 419 is provided inside the ground track 2. The second driving motor 417 drives the gear 418, and the gear 418 is in meshing connection with the rack 419, thereby driving the mobile trolley 4 to move forward, backward, and horizontally.

[0034] As an alternative embodiment, a counterweight 44 is provided on the mobile trolley 4. The counterweight 44 prevents the machine base from tipping over due to excessive weight of the weights, in order to improve the stability of the mobile trolley 4.

[0035] As an alternative embodiment, a car 5 is provided at the end of the ground track 2. The car 5 is used for placing weights.

[0036] As an alternative embodiment, a lifting motor 12 is mounted on the jib crane 1. The lifting motor 12 is connected to the first magnetic material suction device 11 to move the first magnetic material suction device 11 up and down. A steel wire is connected to the first magnetic material suction device 11. Rotation of the lifting motor 12 will retract or release the steel wire, thereby moving the first magnetic material suction device 11 up and down.

[0037] As an alternative embodiment, a lateral movement mechanism 13 is mounted on the jib crane 1. The lifting motor 12 is mounted under the lateral movement mechanism 13. The lateral movement mechanism 13 can move horizontally on the jib crane 1, increasing the area of the region where the weights can be lifted.

[0038] As an alternative embodiment, a plurality of limiting blocks 31 are provided on the weight frame 3. The limiting blocks 31 are located at the edge position of the weight frame 3. The end of the limiting block 31 is provided with an inclined opening. When the weights are moved onto the weight frame 3, in order to place the weights more accurately, the inclined opening on the limiting block 31 plays a positioning role, making the position more accurate.

[0039] In the prior art, during the process of placing weights, weights are generally manually lifted one by one and placed on the car and counterweight car. The problem with this method is that the manual labor intensity is high and the efficiency is low. Therefore, an automatic weight loading device is provided. By using a cantilever crane 1, a ground rail 2, a weight frame 3, and a moving trolley 4, the first magnetic material suction device 11 is arranged on the cantilever crane 1 to suck the weights, and then the weights are placed on the weight frame 3. The moving trolley 4 moves in front of the weight frame 3 and sucks the weights through the second magnetic material suction device 42, and moves the weights into the car, thus reducing the manual labor intensity, improving the production efficiency, and reducing the cost.

[0040] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement methods and are all included in the protection scope of the present invention.
