DETAILED DESCRIPTION

All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] In the description of this application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the application is usually placed when in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as a limitation on this application.

[0034] The features and performance of the present application are further described in detail below with reference to the embodiments.

[0035] Example 1: This embodiment provides an automatic unloading device structure that can be remotely controlled by a cluster, such as Figures 1 to 8 As shown, it comprises: an upper body 3 and a lower body 6 which are fixedly connected, the top of the upper body 3 is fixedly connected to a suspension head 1, one end of the bottom of the lower body 6 is hinged to a hook head 9, and the other end is hinged to a locking tongue 12;

[0036] An electromagnetic push-pull device 5 is installed inside the lower body 6. The bottom of the push-pull rod 15 of the electromagnetic push-pull device 5 is connected to the limit rod 7. The top of the hook head 9 is provided with a limit groove 17 that matches the size of the limit rod 7.

[0037] When lifting cargo, the electromagnetic push-pull device 5 pushes the limit rod 7 into the limit groove 17 to lock the hook head 9 with the lower body 6 to prevent the hook head from rotating during cargo lifting.

[0038] When the cargo is hoisted to the designated location, the electromagnetic push-pull device 5 pulls the limit rod 7 out of the limit slot 17, so that the hook head rotates to the bottom under the action of its own gravity and the pulling force of the cargo, thereby realizing automatic unhooking.

[0039] like Figure 3 As shown, a core shaft through hole 13 is opened in the middle of the upper body 3, and a suspension core shaft 2 is inserted into the core shaft through hole 13. The top end of the suspension core shaft 2 passes through the top of the core shaft through hole 13 and is fixedly connected to the suspension head 1, and the base of the suspension core shaft 2 is clamped in the clamping groove at the bottom of the core shaft through hole 13;

[0040] The suspension head 1 is fixedly connected to the upper body 3 via the suspension core shaft 2, and the suspension head 1 is installed at the bottom of the lifting frame of a crane or a crane boom.

[0041] like Figure 4 As shown, a main body inner cavity 4 is opened in the middle of the lower main body 6, and a limit rod sliding cavity is opened vertically at the bottom of the main body inner cavity 4, and the electromagnetic push-pull device 5 is fixedly installed in the main body inner cavity 4.

[0042] Furthermore, the electromagnetic push-pull device 5 includes an electromagnetic drive mechanism 14 and a push-pull rod 15, and a spring 16 is connected between the electromagnetic drive mechanism 14 and the push-pull rod 15. Figure 7 As shown, the bottom of the push-pull rod 15 is connected to the limit rod 7, and the limit rod 7 is slidably arranged in the limit rod sliding cavity.

[0043] Furthermore, the electromagnetic drive mechanism 14 drives the limit rod 7 to move vertically along the limit rod sliding cavity through the push-pull rod 15; and after the limit rod 7 extends out of the limit rod sliding cavity, it engages with the limit groove 17 provided on the top of the hook head 9;

[0044] Specifically, when the electromagnet of the electromagnetic push-pull device 5 is not energized, the push-pull rod 15 extends downward under the action of the spring 16, so that the limit rod 7 is stuck in the limit groove 17; when the electromagnet of the electromagnetic push-pull device 5 is energized, the electromagnet attracts and pulls the limit rod out of the limit groove to release the restriction on the rotation of the hook head.

[0045] Furthermore, the hook head 9 is hinged to one end of the bottom of the lower body 6 through the hook head pin 8, and the lock tongue 12 is hinged to the other end of the bottom of the lower body 6 through the lock tongue pin 11.

[0046] Furthermore, a torsion spring 10 is connected between the lock tongue 12 and the lock tongue pin 11. During the cargo lifting process, the lock tongue 12 is tightly attached to the end of the hook head under the action of the torsion spring 10.

[0047] like Figure 9 As shown, there are a plurality of automatic removing and unloading devices, and the electromagnetic push-pull devices 5 of the plurality of automatic removing and unloading devices are connected to the power module 18 through a power bus, and an on-off electric control module 19 is connected in series to the power bus, and the on-off electric control module 19 is wirelessly connected to the remote control terminal 20.

[0048] Furthermore, the multiple automatic unloading devices are all installed at the bottom of the lifting frame of the crane or crane arm, and the specific installation quantity and installation position correspond to the quantity and position of the goods to be lifted in a single time.

[0049] When used specifically:

[0050] Step 1. Preparation: Install a number of automatic unloading devices at the bottom of the crane or hoist boom's lifting frame, based on the actual lifting requirements. Before using the automatic unloading devices, thoroughly inspect all components to ensure they are intact. Pay special attention to any signs of wear, deformation, or damage, and ensure that all connections are secure and reliable.

[0051] Step 2. Hooking: During this stage, the automatic unhooking device should be in the unhooked state, with the hook head naturally hanging down. The operator hooks the lifting rope connected to the cargo onto the hook head and manually rotates the hook head so that its upper limit slot aligns with the limit rod. At this point, the electromagnetic push-pull mechanism is de-energized, and the internal spring forces the limit rod into the limit slot, locking the hook head and preventing it from rotating, thus completing the hooking operation.

[0052] Step 3. Lifting Phase: Start the lifting equipment and slowly raise the load, gradually applying force to the device. Each component of the equipment utilizes a high-strength mechanical structure and high-quality metal materials, enabling it to reliably lift loads within the specified weight limit, ensuring safety and stability during the lifting process.

[0053] Step 4. Unhooking: Once the cargo has been hoisted to the designated location, the operator uses a handheld remote control terminal to send a signal to the electronic control module within the device. Upon receiving the signal, the module energizes the electromagnetic push-pull mechanism, which engages the electromagnet and pulls the limit rod out of the slot, releasing the restriction on the hook's rotation. Under its own weight, the hook rotates downward, achieving automatic unhooking and completing the entire hoisting task.

[0054] Embodiment 2: The structure and technical solution of this embodiment are basically the same as those of embodiment 1, except that a pressure sensor for monitoring the weight of the hoisted object is installed on the suspension head 1 of this embodiment, and the pressure sensor is electrically connected to the on-off control module 19;

[0055] When the pressure borne by the pressure sensor exceeds the preset value, a signal will be sent to the on-off electrical control module 19 to keep the power supply line of the corresponding electromagnetic push-pull device 5 always disconnected; thus, during the lifting process, even if the operator accidentally presses the unhooking button of the remote control terminal, the electromagnetic push-pull device will not respond, thereby effectively avoiding unhooking under heavy load conditions due to human error, and preventing damage to the goods and economic losses.

[0056] Furthermore, the on-off electric control module 19 includes an on-off switch with a relay remote control, which can realize the on-off control of the power supply of the electromagnetic push-pull device through remote control.

[0057] Furthermore, during lifting operations, the number of automatic unloading devices on the frame to which the crane or hoist is attached can be flexibly adjusted based on actual needs. Specifically, the number and location of automatic unloading devices can be dynamically adjusted and installed based on the quantity and arrangement of cargo in a single lift. This design allows the crane or hoist to adapt to a variety of lifting tasks, thereby improving operational efficiency and flexibility. This dynamic allocation mechanism ensures that each lifting operation is completed in the shortest possible time, while minimizing waste of manpower and material resources and ensuring safe and efficient operations.

[0058] Furthermore, all parts of this application that are not described in detail are the same as the existing technology or are implemented using the existing technology.

[0059] In summary:

[0060] 1. The utility model makes the overall disassembly and assembly of the equipment convenient and flexible through the reasonable arrangement of the suspension head, suspension core shaft, upper body, lower body, hook head and corresponding connecting parts, and can stably and reliably bear the corresponding weight of cargo. Moreover, through the coordination of multiple unloading devices, the weight of the cargo can be effectively distributed and transmitted to the entire lifting frame, thereby ensuring the stability and sufficient strength of the entire structure.

[0061] 2. The utility model ensures smooth unhooking and hooking operations by arranging an electromagnetic push-pull device and a limit rod in the inner cavity of the equipment body, and opening a limit groove with a size and position that matches the top of the hook head. In addition, the reasonable arrangement of the power supply line, the on-off electric control module, and the remote control terminal can conveniently realize the locking of the hook head and the automatic unhooking of the spreader, which can greatly reduce the labor intensity of workers, reduce labor costs, and enhance the safety of operations.

[0062] 3. According to the actual lifting requirements of the goods to be lifted, the utility model arranges and installs a corresponding number of automatic unloading devices at the bottom of the lifting frame of the crane or crane arm, and the electromagnetic push-pull devices of multiple automatic unloading devices are connected to the power module through a unified power bus.
