Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] 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, further definition and explanation thereof is not required in subsequent drawings.

[0018] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0019] See Figures 1 to 6 , an automatic sling for coiled electrician aluminum rods, including a suspension frame 1 and a four-sided frame 6. A support plate 7 is arranged on the four-sided frame 6, a lifting arm 5 is arranged on the support plate 7, a clamping gripper 9 is arranged at the lower end of the lifting arm 5, and a rubber belt 10 is arranged on the clamping gripper 9; the upper end of the lifting arm 5 is connected to the suspension frame 1 through a lifting plate 3.

[0020] Specifically, the four-sided frame 6 has four corners, and there are four lifting arms 5, which are respectively arranged at the four corners of the four-sided frame 6. A clamping gripper 9 is arranged on each lifting arm 5. Support plates 7 are respectively arranged on a set of opposite corners of the four-sided frame 6, and support frames 11 are respectively arranged on the other set of opposite corners of the four-sided frame 6. The lifting and unloading functions of the sling are mainly realized by a switching mechanism arranged in the support plate 7. Further, a lifting arm cylindrical pin 8 is arranged on each support plate 7 and support frame 11, and each lifting arm 5 is respectively arranged on the support plate 7 and support frame 11 through the lifting arm cylindrical pin 8.

[0021] Each lifting arm 5 is connected to the lifting plate 3 (it can be imagined that the lifting plate 3 also has four) through a lifting plate cylindrical pin 4. The lifting plate 3 is connected to the suspension frame 1 through a suspension frame cylindrical pin 2. A lifting ring is arranged on the suspension frame 1. Among them, the lifting plate 3 can rotate through the suspension frame cylindrical pin 2, and the lifting arm 5 can rotate through the lifting plate cylindrical pin 4 and the lifting arm cylindrical pin 8.

[0022] The realization process of the lifting function: The crane hook hooks the lifting hole of the suspension frame 1 and moves upward, drives the four lifting plates 3 to move upward through the suspension frame cylindrical pin 2, drives the four lifting arms 5 to rotate respectively around the axis of the lifting arm cylindrical pin 8 of the support plate 7 and the support frame 11 through the lifting plate cylindrical pin 4, and drives the four clamping claws 9 and the rubber belt 10 to contract towards the center of the aluminum coil, thereby clamping the aluminum coil. At this time, the automatic switching part of the lifting and unloading functions is in the lifting state; when in the unloading state, the aluminum coil is lowered. The functions of the rubber belt 10: One is to increase the lifting friction to facilitate the lifting of the aluminum coil; the other is to protect the surface of the aluminum coil from being scratched.

[0023] In this embodiment, the main functions of the lifting and unloading of the sling are to lift aluminum coils and unload aluminum coils, and the automatic switching is mainly achieved through a switching mechanism, which mainly includes the following components: ratchet 12, pawl 13, pin 27, spring seat cylindrical pin 14, spring seat 15, compression spring 16, cylindrical pin with cylindrical step 17, pawl arm 19, pawl arm pulling block 18, screw 20, pawl arm reset tension spring 21 and unloading block 22. A spring seat cylindrical pin 14 is provided on the spring seat 15, and the spring seat 15 is arranged on the support plate 7 through the spring seat cylindrical pin 14; a pin 27 is provided on the pawl arm 19, and a pawl 13 is provided on the pin 27, and the pawl 13 is connected to the ratchet 12, and the ratchet 12 is provided with an end face cam at one end of the spring seat 15; one end of the pawl arm toggle block 18 is connected to the lifting arm 5, and the other end is connected to the pawl arm 19 through a screw 20, and a pawl arm reset tension spring 21 is also provided on the pawl arm 19. In order to accurately control the circumferential phase of the ratchet 12, a reset pawl 25 is also provided, and the reset pawl 25 is installed on the supporting block 26 on the spring seat 15 and fixed by a pin; the cylindrical pin 17 with a cylindrical step is connected to the spring seat 15 through a compression spring 16, and the lifting arm 5 is provided with a discharge block 22 for limiting the cylindrical pin 17 with a cylindrical step.

[0024] Furthermore, a ratchet compression spring 23 and a fixing screw 24 are also provided on the ratchet 12 . One end of the ratchet compression spring 23 is connected to the fixing screw 24 , and the other end is tightly attached to the end surface of the fixed spring seat 15 .

[0025] The switching implementation process of lifting and unloading of the present invention is as follows: Before each lifting, the sling is in the unloading state, that is, the aluminum coil in the sling has been put down. When the aluminum coil needs to be lifted, the crane lowers the sling to the aluminum coil to be lifted, and the four-side frame 6 and related parts of the sling stop descending. The lifting plate 3 and the lifting arm 5 of the sling 1 continue to descend, and the lifting arm 5 gradually rotates in the opposite direction around the cylindrical pin 8 of the lifting arm, rotates together through the ratchet arm toggle block 18 connected to the lifting arm 5, and the ratchet arm 19 rotates clockwise around the spring seat cylindrical pin 14 through the screw 20, and then drives the ratchet 13 through the pin 27 to make the ratchet 12 rotate synchronously around the spring seat cylindrical pin 14. The ratchet 12 is provided with an end cam near the spring seat 15, and the end cam is in the trough state at this time. Under the action of the compression spring 16, the cylindrical pin 17 with a cylindrical step installed in the spring seat 15 withdraws from the unloading block 22 on the lifting arm 5. At this time, the lifting arm 5 drops to the lowest position and the descent ends.

[0026] Then, the crane starts to move the hoist upward to lift the aluminum coil. During the lifting process, as the hoisting arm 5 rotates around the hoisting arm cylindrical pin 8, the pawl arm 19 is reset under the action of the pawl arm reset tension spring 21, and the pawl 13 is reset at the same time. In order to accurately control the circumferential phase of the ratchet 12, a reset pawl 25 is also provided. The reset pawl 25 is installed on the support block 26 on the spring seat 15. The support block 26 is also fixed by a pin. The pawl 13 and the reset pawl 25 are tightly attached to the ratchet tooth surface by their own gravity.

[0027] When unloading the aluminum coil, the crane hoists the aluminum coil into the unloading position and then puts the aluminum coil in place. The crane continues to descend, and the lifting arm 5 gradually rotates around the lifting arm cylindrical pin 8, and also rotates with it through the ratchet arm pull block 18 on the lifting arm 5, thereby driving the ratchet arm 19 and the ratchet 13, and the ratchet wheel 12 rotates synchronously around the spring seat cylindrical pin 14 through the ratchet 13. The wave crest of the end face cam of the ratchet wheel 12 pushes the cylindrical pin 17 with a cylindrical step to overcome the elastic force of the compression spring 16 and extend downward, clamping the unloading block 22, and the lifting arm 5 descends to the lowest position and ends. At this time, the crane goes up, and the lifting arm 5 is clamped by the cylindrical pin 17 with a cylindrical step, and can no longer clamp the aluminum coil, realizing the function of unloading the aluminum coil. This cycle of work is repeated, and the ratchet 13 and the ratchet arm 19 are reset under the action of the ratchet arm reset tension spring 21, preparing for the next action.

[0028] It should also be pointed out that a ratchet compression spring 23 and a fixing screw 24 are also provided in the ratchet 12, and one end of the ratchet compression spring 23 is closely attached to the end face of the stationary spring seat 15. When the hoisting arm 5 descends through the ratchet arm pulling block 18, driving the ratchet arm 19, the ratchet 13 and the ratchet 12 to rotate clockwise, the ratchet 12 must overcome the friction force of the ratchet compression spring 23 on the end face of the spring seat 15 to rotate, so as to avoid the ratchet 12 from overshooting due to the inertia force, so as to maintain the correct position of the ratchet 12, and the ratchet compression spring 23 plays a damping role.
