Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically to a forklift hook lifting device. Background Technology

[0002] Forklifts are industrial handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. When transporting goods, forklifts typically insert their fork arms into the bottom of the goods or into the fork arm holes of the pallet, and then lift the goods to achieve transportation.

[0003] While existing forklifts can achieve short-distance transportation of goods or palletized goods, they have the drawback of being inconvenient for transporting rolled goods. Rolled goods have a cylindrical structure, and when the forklift arm transports them, there is a high risk of the rolled goods falling off during the forklift's movement. For example, when finished aluminum coils are produced and need to be transported short distances by forklift, the finished aluminum coils are located on the forklift arm and are very likely to fall off the forklift arm, and the forklift arm can also easily damage the finished aluminum coils. Summary of the Invention

[0004] This invention addresses the problem that existing forklift arms are inconvenient for transporting rolled goods. This device works in conjunction with the forklift arms and lifting straps to lift rolled goods, facilitating their transport and effectively preventing them from falling during transport.

[0005] To achieve the above objectives, the technical solution of this utility model is: a forklift hook lifting device, including a lifting base and a hook assembly disposed below the lifting base. The lifting base includes a lifting frame and side fixing plates disposed on both sides of the lifting frame. The side fixing plates have square holes corresponding to the openings of the lifting frame. Two fork arm assemblies are symmetrically arranged inside the lifting frame. The square hole design allows the fork arm assemblies to be installed inside the lifting frame. The fork arm assemblies cooperate with the forklift arms of the forklift, allowing the forklift arms to insert into the fork arm assemblies, thus lifting the lifting base. This, in turn, allows the rolled goods to be lifted by the hook assembly. A lifting strap is fitted onto the rolled goods and attached to the hook assembly.

[0006] The fork arm assembly includes a fork arm seat disposed inside the lifting frame. Both ends of the fork arm seat are connected to fixing plates located outside the side fixing plates, and the fixing plates are detachably connected to the side fixing plates. The lifting frame is provided with a clamping member that passes through the lifting frame and the bottom plate of the fork arm seat in sequence. The forklift arm can be inserted into the fork arm seat, and the fork arm seat can move within the lifting frame to adjust the distance between the fork arm seats of the two fork arm assemblies, so that the device can be used for forklift arms of different models of forklifts. The clamping member is used to clamp the forklift arm inserted into the fork arm seat to improve stability.

[0007] A hook plate is fixedly installed at the bottom of the hoisting frame, and the hook plate is connected to the hook assembly; wherein the hook plate is used to connect the hook assembly so as to install the hook assembly to the bottom of the hoisting frame.

[0008] Furthermore, a number of reinforcing plates are evenly spaced on the top of the hoisting frame. The reinforcing plates are located between two side fixing plates and are fixedly connected to the side fixing plates. The reinforcing plates play a role in stabilizing and strengthening the connection between the side fixing plates and the hoisting frame, thereby improving the structural strength.

[0009] Furthermore, the fixing plate has square holes corresponding to the opening of the fork arm seat. Locking bolts are provided on both the upper and lower parts of the fixing plate, and several threaded holes matching the locking bolts are equally spaced on both the upper and lower parts of the side fixing plate. The design of the holes on the upper part of the fixing plate ensures that the forklift arm can be inserted into the fork arm seat. The locking bolts fix the fixing plate to the outside of the side fixing plate, thereby securing the fork arm seat. Simultaneously, the position of the fork arm seat within the lifting frame can be adjusted by the cooperation of the locking bolts and the threaded holes.

[0010] Furthermore, the bottom plate of the lifting frame is provided with several threaded holes at equal intervals; a through hole is provided in the middle of the bottom plate of the fork arm seat. The design of the threaded holes and the through hole allows the clamping member to be inserted into the fork arm seat and clamp the forklift arm of the forklift.

[0011] Furthermore, the clamping component is a clamping screw, which is threadedly connected to the base plate of the lifting frame through a second threaded hole. A rotating handle is threadedly connected to the lower end of the clamping screw, which extends through the second threaded hole and a through hole into the fork arm seat, and is threadedly connected to a threaded cylinder. A clamping plate is fixedly mounted on the top of the threaded cylinder. The position of the clamping screw can be adjusted through the second threaded hole, allowing it to clamp the fork arm at different positions according to the position of the fork arm seat.

[0012] Furthermore, the hook assembly includes a lifting ring and a hook attached to the lifting ring, the lifting ring being mounted on a hook plate. The hook can be used to attach lifting straps, thereby enabling the forklift arm to easily transport rolled goods.

[0013] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. It facilitates the transportation of rolled goods by forklifts. By cooperating with the lifting belt and the forklift arm, it can lift and transport rolled goods, effectively avoiding the phenomenon of rolled goods falling during transportation and reducing the risk of rolled goods falling.

[0014] The fork arm seat of the internal fork arm assembly of this utility model provides an insertion position for the forklift arm of the forklift. By attaching the lifting sling to the rolled goods and hanging it on the hook assembly, and inserting the forklift arm into the fork arm seat, the forklift arm can lift the lifting seat, thereby achieving the effect of lifting and transporting the rolled goods by the forklift arm, and making it easier for the forklift to transport rolled goods.

[0015] This invention uses locking bolts to fix the fixing plate to the outside of the side fixing, thereby fixing the fork arm seat. The locking bolts and threaded holes allow for adjustment of the position of the fork arm seat within the lifting frame, thus adjusting the distance between the fork arm seats of the two fork arm assemblies. The distance between the fork arms of different tonnage forklift models varies, making this device applicable to forklift arms of different models and increasing its applicability.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-4As shown, a forklift hook lifting device includes a lifting base and hook assemblies disposed below the lifting base. The lifting base includes a lifting frame 1 and side fixing plates 2 disposed on both sides of the lifting frame 1. The lifting frame 1 has openings on both sides to provide installation positions for the fork arm assemblies. The side fixing plates 2 have square holes corresponding to the openings of the lifting frame 1. The square holes are designed to allow the fork arm assemblies to be installed inside the lifting frame 1 and to adjust their position inside the lifting frame 1. Two fork arm assemblies are symmetrically arranged inside the lifting frame 1. In this embodiment, when transporting rolled goods by a forklift, the forklift arms are inserted into the two fork arm assemblies. The forklift arms lift the lifting base upwards, causing the lifting base to lift the hook assemblies. A lifting strap is then placed on the rolled goods and hooked onto the hook assemblies, achieving the effect of lifting and transporting rolled goods by the forklift using this device.

[0019] The fork arm assembly includes a fork arm seat 4 disposed inside the lifting frame 1. Both ends of the fork arm seat 4 are connected to fixing plates 5 located outside the side fixing plates 2. The fixing plates 5 are detachably connected to the side fixing plates 2. The lifting frame 1 is provided with a clamping member that passes sequentially through the bottom plate of the lifting frame 1 and the fork arm seat 4. In this embodiment, the fixing plates are used to fix the fork arm seat 4. The fixing plates 5 are detachably connected to the side fixing plates 2. When the fixing plates 5 are removed, the fork arm seat 4 can move inside the lifting frame 1, adjusting its position within the lifting frame 1, thereby adjusting the distance between the fork arm seats 4 of the two fork arm assemblies. This allows the device to be adapted to fork arm arms of different forklift models. When the forklift arm is inserted into the fork arm seat 4, rotating the clamping member pushes its upper end against the forklift arm, improving the stability of the forklift arm insertion into the lifting seat.

[0020] A hook plate 13 is fixedly installed at the bottom of the hoisting frame 1, and the hook plate 13 is connected to the hook assembly. In this embodiment, the hook plate 13 is located at the middle position of the bottom of the hoisting frame 1, and the hook plate 13 is fixedly connected to the hoisting frame 1 and the side fixing plates 2 on both sides of the hoisting frame 1. The hook plate 13 is used to connect the hook assembly so as to suspend the hook assembly below the hoisting base.

[0021] The top of the hoisting frame 1 is provided with several reinforcing plates 3 at equal intervals. The reinforcing plates 3 are located between two side fixing plates 2 and are fixedly connected to the side fixing plates 2. In this embodiment, there are three reinforcing plates 3. The reinforcing plates 3 play a role in stabilizing and strengthening the connection between the hoisting frame 1 and the side fixing plates 2, thereby improving the structural strength of the connection between the two.

[0022] The fixing plate 5 has square holes corresponding to the openings of the fork arm seat 4. Locking bolts 6 are provided on both the upper and lower parts of the fixing plate 5. The upper and lower parts of the side fixing plate 2 are equally spaced and have several threaded holes 7 that match the locking bolts 6. In this embodiment, the square hole design ensures that the forklift arm can be inserted into the fork arm seat 4. The locking bolts 6 are used to fix the fixing plate 5 to the outside of the side fixing plate 2. Each group has seven threaded holes 7. After removing the locking bolts 6, the fork arm seat 4 can move inside the lifting frame 1. The positions of the two fork arm seats 4 can be adjusted according to the distance between the forklift arms. The locking bolts 6 cooperate with the corresponding threaded holes 7 to fix the fixing plate 5, thereby fixing the fork arm seat 4. Through the cooperation of the locking bolts 6 and the threaded holes 7, the position of the fork arm seat 4 within the lifting frame 1 is adjusted, so that the device can be used with forklift arms of different models, improving its applicability.

[0023] The bottom plate of the lifting frame 1 is provided with a plurality of threaded holes 8 at equal intervals; a through hole is provided at the middle position of the bottom plate of the fork arm seat 4. In this embodiment, each group has five threaded holes 8. The structural design of the threaded holes 8 and the through hole allows the clamping member to extend into the interior of the fork arm seat 4 and clamp onto the fork arm inserted into the fork arm seat 4.

[0024] The clamping component is a clamping screw 9, which is threadedly connected to the base plate of the lifting frame 1 through a threaded hole 8. A rotating handle 10 is threadedly connected to the lower end of the clamping screw 9, which extends through the threaded hole 8 and a through hole into the fork arm seat 4 and is threadedly connected to a threaded cylinder 11. A clamping plate 12 is fixedly mounted on the top of the threaded cylinder 11. In this embodiment, the rotating handle 10 is designed to facilitate the rotation of the clamping screw 9 by the operator. The diameter of the clamping plate 12 is larger than the outer diameter of the threaded cylinder 11, which increases the contact area with the forklift arm, improves the clamping effect on the forklift arm, and thus enhances the stability of the forklift arm's insertion into the lifting seat. The position of the clamping screw 9 can be adjusted through the threaded hole 8, allowing the clamping screw 9 to clamp the forklift arm at different positions according to the position of the fork arm seat 4.

[0025] The hook assembly includes a lifting ring 14 and a hook 15 hung on the lifting ring 14, which is attached to a hook plate 13. In this embodiment, a pin hole is provided at the lower part of the hook plate 13, and the lifting ring 14 is attached to the hook plate 13 by the engagement of a pin with the pin hole.

[0026] The working principle of this utility model is as follows: First, adjust the position of the two fork arm assemblies 4 according to the distance between the two fork arms of the forklift, ensuring that the two fork arms can be inserted into the two fork arm assemblies 4 respectively. After adjusting the position of the two fork arm assemblies 4, fix the fixing plate 5 by screwing the locking bolt 6 into the corresponding threaded hole 7, thereby fixing the fork arm assemblies 4. Then, screw the tightening screw 9 into the threaded hole 8 corresponding to the through hole on the bottom plate of the fork arm assemblies 4, extending the upper end of the tightening screw 9 into the interior of the fork arm assemblies 4. Finally, thread the threaded cylinder 11 to the upper end of the tightening screw 9.

[0027] When transporting rolled goods by forklift, the two forklift arms are inserted into the two forklift seats 4 respectively. The operator rotates the handle 10 to rotate the tightening screw 9 until the tightening plate 12 is tightened to the bottom of the forklift arm. Then the forklift arm lifts the lifting seat upwards, and the lifting seat drives the hook assembly to lift. The lifting strap is then placed on the rolled goods and hung on the hook 15 of the hook assembly. The forklift arm continues to lift upwards until the rolled goods are lifted off the ground or the pallet. Finally, the forklift can move to transport the rolled goods.
