Technical Field

[0001] This utility model belongs to the field of ingot hoisting technology, specifically relating to the structure of a horizontal hoisting clamp ratchet-type unhooking device for aluminum square ingots. Background Technology

[0002] In the recycling process, aluminum alloy scrap is usually processed into square ingots. Traditionally, aluminum alloy square ingots are transported by hoisting, often using a hanging plate-type hook, which requires manual operation to open and close.

[0003] The existing hanging-plate type unhooking and handling method for aluminum square ingots requires one person to stand next to the lifting device to operate each time the ingot is lifted. On the one hand, it increases labor costs, and on the other hand, if the hook and the hanging point are not tightly connected, they are easy to fall off, causing safety problems, which has certain limitations. Summary of the Invention

[0004] The purpose of this utility model is to provide a ratchet-type unhooking device structure for horizontal lifting clamps of aluminum square ingots, so as to solve the problem mentioned in the background art that existing aluminum square ingots waste manpower and pose certain dangers during the handling process. This device adopts the principle of ratchet steering, similar to the rotation of a traditional automatic ballpoint pen, to realize the automatic opening and closing of the lifting clamp, that is, the automatic clamping or releasing of the square ingot operation without the need for manual intervention, which has certain limitations.

[0006] Preferably, the inner side of the two fixed clamps is provided with a protective pad, and the inner side of the protective pad is fixedly provided with an anti-slip groove.

[0007] Preferably, the ratchet device includes a housing, a spindle, a baffle, and a pin. The spindle is slidably sleeved inside the housing, and ratchet grooves are provided on both sides of the center of the spindle.

[0008] Preferably, the inner wall of the outer casing is fitted with a pin, and the outer end of the outer casing is threadedly fixedly connected with a baffle, which is located outside the pin.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model adopts the ratchet steering principle. Based on the weight of the clamp itself, the ratchet device is pressed, similar to the principle of a ballpoint pen, so as to realize the automatic opening and closing of the clamp, that is, the automatic clamping or loosening of the square ingot operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a horizontal lifting clamp ratchet-type unhooking device structure for aluminum square ingots, including a hook 1, a clamp block 2 connected to the lower end of the hook 1, connecting arms 3 rotatably connected to both sides of the lower end of the clamp block 2, a rotating cross arm 4 rotatably connected to one end of the connecting arms 3, the center of the rotating cross arm 4 being rotatably limited by a limiting post 15, a fixing clamp plate 5 fixedly connected to one side of the rotating cross arm 4, a connecting block 6 connected to the lower end of the clamp block 2, a ratchet device 7 fixedly connected to the lower end of the connecting block 6, a hook head 16 provided at the lower end of the ratchet device 7, and a base plate 8 fixedly connected to one end of the limiting post 15.

[0018] In this embodiment, during use, the aluminum square ingot is clamped, and the base plate 8 is placed against the upper end of the ingot. At this time, under the gravity of the lifting clamp block 2, the ratchet device 7 is driven to abut against the upper end of the groove of the base plate 8. Under the gravity of the lifting clamp block 2, the ratchet device 7 is pressed, causing the spindle of the ratchet device 7 to rotate 90 degrees, causing the hook head 16 to rotate 90 degrees, thereby hooking the base plate 8, and then lifting. At this time, the fixed clamping plates 5 on both sides are subjected to force to clamp the square ingot, thereby completing the stabilization. After being hoisted to a fixed position, the ratchet device 7 rotates 90 degrees again under the gravity of the clamp block 2, allowing the hook head 16 to rotate 90 degrees to disengage from the base plate 8, thus completing the automatic opening and closing without manual intervention. This design adopts the ratchet steering principle, using the weight of the clamp itself to press the ratchet device 7, similar to the principle of a ballpoint pen, realizing the automatic opening and closing of the clamp, which is the automatic clamping or loosening required for the casting operation.

[0019] Specifically, protective pads 9 are provided on the inner side of the two fixed clamping plates 5, and anti-slip grooves 10 are fixedly opened on the inner side of the protective pads 9.

[0020] In this embodiment, the protective pad 9 connected to the inside of the fixed clamp 5 can play a certain protective role, while the anti-slip groove 10 can increase the friction of the surface to prevent disengagement.

[0021] Specifically, the ratchet device 7 includes a housing 11, a spindle 12, a baffle 13, and a pin 14. The spindle 12 is slidably sleeved inside the housing 11, and ratchet grooves are provided on both sides of the center of the spindle 12.

[0022] In this embodiment, a groove is provided in the center of the mandrel 12, and ratchet wheels are provided on both sides of the groove.

[0023] Specifically, the inner wall of the outer casing 11 is fitted with a pin post 14, and the outer end of the outer casing 11 is threadedly fixedly connected with a baffle 13, which is located outside the pin post 14.

[0024] In this embodiment, the baffle 13 can limit the position of the pin 14. Under the limiting action of the internal pin 14, the spindle 12 can rotate 90 degrees in both up and down movements through the ratchet provided on both the upper and lower sides, thus completing automatic opening and closing, which is more convenient. In use, the base plate 8 is placed against the upper end of the square ingot. At this time, under the gravity of the lifting clamp block 2, the ratchet device 7 is driven to abut against the upper end of the groove of the base plate 8. Under the gravity of the lifting clamp block 2, the ratchet is pressed down. The ratchet device 7 rotates its spindle 90 degrees, causing the hook head 16 to rotate 90 degrees and hook onto the base plate 8 for lifting. At this time, the fixed clamping plates 5 on both sides are subjected to force to clamp the square ingot, thus completing the stable lifting. After being lifted to the fixed position, similarly, under the gravity of the lifting clamp block 2, the ratchet device 7 is pressed to rotate 90 degrees again, so that the hook head 16 can rotate 90 degrees to disengage from the base plate 8, completing the automatic opening and closing without manual intervention.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
