[0001] This utility model relates to the field of lifting devices for forklifts, specifically a lifting device for use with off-road forklifts. Background Technology

[0002] In logistics transportation, construction and various industrial production scenarios, off-road forklifts are widely used for cargo handling and loading / unloading due to their powerful off-road performance and flexible maneuverability.

[0003] However, while existing lifting devices for use with off-road forklifts on the market meet basic lifting needs to a certain extent, the goods are suspended by simple ropes or chains during the lifting process, lacking effective stabilization and anti-fall measures. In the event of emergencies, such as external impact to the lifting device, shaking during the lifting process, or aging and loosening of connecting parts, the goods are very likely to fall. Moreover, falling goods not only pose a serious threat to the lives of on-site personnel, causing irreparable casualties, but also damage surrounding equipment, facilities, and the goods themselves, resulting in huge economic losses. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a lifting device for use with off-road forklifts, in order to solve the technical problems of unstable cargo suspension, lack of anti-fall measures, easy cargo falling due to sudden situations, endangering personnel safety, damaging equipment and goods, and causing economic losses in existing lifting devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for use with an off-road forklift, comprising a lifting device, wherein the lifting device includes a mounting frame, and a stabilizing mechanism is fixedly connected to the top of the mounting frame by mounting bolts;

A hanging rod is provided on the inner side of the connecting base, and a hanging ring is hung on the hanging rod. A traction steel cable is provided on the back of the hanging ring, and one end of the traction steel cable is provided with a C-shaped frame that is attached to the forklift frame. A second tightening screw is screwed to the outer surface of the C-shaped frame, and a second abutment block is provided at the end of the second tightening screw.

[0007] By adopting the above technical solution, the mounting frame is combined with the stabilizing mechanism, which enhances the stability during lifting, prevents the cargo from swaying, ensures a safe and stable lifting process, reduces the risk of cargo falling, and improves the safety and reliability of the operation.

[0008] Furthermore, the stabilizing mechanism is made of high-carbon steel, and the traction cable is made of carbon steel.

[0009] By adopting the above technical solution, the stabilizing mechanism is made of high carbon steel and the traction cable is made of carbon steel. The high-strength materials ensure that the stabilizing mechanism and the traction cable can withstand greater tension, are not easily deformed or broken, extend their service life, and adapt to harsh lifting environments.

[0010] Furthermore, two fork slots extend through both sides of the mounting bracket, and a first tightening screw is screwed to the bottom of the fork slot. A first abutting block that abuts against the fork is provided on the top of the first tightening screw.

[0011] By adopting the above technical solution, fork slots are provided on both sides of the mounting frame, and a first tightening screw and a first abutment block are provided at the bottom, which can firmly fix the forks, prevent the forks from separating from the device during lifting, ensure the smooth progress of lifting operations, and improve operational safety.

[0012] Furthermore, a mounting plate is provided at the bottom axis of the mounting bracket, and a hook is provided at the bottom of the mounting plate, with a hook attached to the hook.

[0013] By adopting the above technical solution, the bottom of the mounting frame is equipped with a mounting plate, hook ring and hook, providing a convenient connection point for lifting goods. The hook can rotate around the hook ring, making it easy to adjust the lifting angle and improve lifting flexibility and efficiency.

[0014] Furthermore, both the first and second abutment blocks have anti-slip structures on their surfaces.

[0015] By adopting the above technical solution, the surfaces of the first and second abutment blocks are provided with anti-slip structures, which can increase the friction with the forks and forklift frame, prevent the abutment blocks from sliding during lifting, make the connection more stable, and improve the safety and stability of lifting.

[0016] Furthermore, the hook can rotate around the hook ring.

[0017] By adopting the above technical solution, the hook can rotate around the hook ring, which makes it convenient to adjust the hook angle according to the position and shape of the goods during lifting, making the goods connection more precise, reducing swaying during the lifting process, and improving the quality and efficiency of lifting operations.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model features a stabilizing mechanism, which is securely mounted on the top of the mounting frame using a fixed base. A hanging ring is attached to the inner side of the connecting base, and a traction steel cable is connected to the back of the hanging ring. One end of the traction steel cable is attached to the forklift frame via a C-shaped bracket, which is clamped and fixed by a second tightening screw and a second abutment block. The stabilizing mechanism as a whole is made of high-carbon steel, and the traction steel cable is also made of carbon steel, ensuring structural strength and stability. This design forms a complete stabilization and anti-fall system, solving the problem that existing lifting devices used with off-road forklifts rely solely on simple ropes or chains for suspension during lifting, lacking effective stabilization and anti-fall measures. This makes them susceptible to falling due to external impacts, lifting sway, aging or loosening of connecting parts, etc., endangering personnel safety, damaging equipment and goods, and causing economic losses.

[0024] 2. This utility model provides fork slots on both sides of the mounting frame, and screws a first tightening screw to the bottom of the fork slot. A first abutment block is provided on the top of the first tightening screw, and the surface of the first abutment block is provided with an anti-slip structure. When the fork is inserted into the fork slot, the first tightening screw is rotated to make the first abutment block tightly abut against the fork. The anti-slip structure further enhances the friction, ensuring a stable connection between the lifting device and the fork. This solves the problem that the connection between the lifting device and the fork is not firm, and the device is prone to separation from the fork during the lifting process due to shaking or uneven force, which affects the safety and efficiency of the lifting operation.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] A lifting device for use with off-road forklifts, such as Figure 1-4 As shown, it includes a lifting device 1, which includes a mounting frame 101. The top of the mounting frame 101 is fixedly connected to a stabilizing mechanism 2 by mounting bolts 103.

[0032] The stabilizing mechanism 2 includes a fixed base 201, which is located on top of the mounting frame 101. A connecting base 202 is located on the top of the mounting frame 101. A hanging rod is located on the inner side of the connecting base 202, and a hanging ring 203 is attached to the hanging rod. A traction cable 204 is attached to the back of the hanging ring 203, and one end of the traction cable 204 is attached to a C-shaped frame 205 for attachment to the forklift frame. A second tightening screw 206 is screwed onto the outer surface of the C-shaped frame 205, and a second abutment block is located at the end of the second tightening screw 206. The top of the C-shaped frame 205 is fixedly connected to the stabilizing mechanism 2 by mounting bolts 103. The stabilizing mechanism 2 effectively disperses and withstands the tensile and swaying forces generated by the cargo during lifting. When the off-road forklift is performing lifting operations, the cargo is prone to swaying due to changes in the center of gravity or external interference. The stabilizing mechanism 2, with its robust connection and reasonable structural design, reduces the swaying amplitude of the cargo, keeping it in a relatively stable state. This not only prevents goods from colliding with surrounding equipment or personnel due to shaking, but also reduces the possibility of goods falling due to violent shaking, greatly improving the safety and reliability of lifting operations.

[0033] See Figure 1 , Figure 2The stabilizing mechanism 2 is made entirely of high-carbon steel, while the traction cable 204 is made of carbon steel. Both materials possess high strength. During lifting operations, the stabilizing mechanism 2 needs to withstand the weight of the cargo and various tensile and stress forces generated during the lifting process. The high-carbon steel stabilizing mechanism 2 ensures structural stability under prolonged, high-load operation, preventing deformation or damage. Similarly, the traction cable 204, as a key component connecting the cargo and the stabilizing mechanism 2, is made of carbon steel, giving it sufficient toughness and tensile strength to withstand the weight of the cargo and the dynamic tensile forces during lifting, reducing the likelihood of breakage. This material selection extends the service life of the lifting device, enabling it to adapt to various harsh lifting environments.

[0034] See Figure 1 , Figure 4 The mounting frame 101 has two fork slots 102 extending through both sides. A first tightening screw 104 is screwed to the bottom of the fork slot 102, and a first abutment block 105 is provided at the top of the first tightening screw 104 to abut against the fork. After the fork is inserted into the fork slot 102, the first tightening screw 104 at the bottom of the fork slot 102 functions. By rotating the first tightening screw 104, the first abutment block 105 at its top is tightly abutted against the fork. During lifting, the cargo will generate significant weight. If the fork is not securely connected to the lifting device, the fork may slip out of the fork slot 102, causing the cargo to fall and potentially leading to an accident. The first abutment block 105 increases the friction between the fork and the fork, firmly securing the fork in the fork slot 102, preventing the fork from separating from the lifting device, ensuring smooth lifting operations, and improving operational safety.

[0035] See Figure 3 , Figure 4 A mounting plate 106 is located at the bottom axis of the mounting frame 101. A hook 107 is located at the bottom of the mounting plate 106, and a hook 108 is attached to the hook 107. This structure provides a convenient connection point for lifting goods. In actual lifting operations, different cargo shapes and lifting requirements may require different lifting angles. The rotatable nature of the hook 108 around the hook 107 allows operators to flexibly adjust the angle of the hook 108 according to the actual condition of the goods, thus better connecting them. This not only facilitates the lifting operation but also ensures that the goods remain balanced during lifting, reducing cargo swaying or damage caused by improper lifting angles, and improving the flexibility and efficiency of lifting operations.

[0036] See Figure 1 , Figure 4 Both the first abutment block 105 and the second abutment block 207 have anti-slip structures on their surfaces, which play a crucial role in lifting operations. The first abutment block 105 abuts against the forks, and the second abutment block 207 abuts against the forklift frame. During lifting, the weight of the goods and the dynamic forces exerted during lifting cause the abutment blocks to be subjected to significant pressure and friction. Without the anti-slip structure, the abutment blocks might slide on the contact surfaces with the forks or forklift frame, leading to a loose connection and affecting the stability and safety of the lifting operation. The anti-slip structure significantly increases the friction between the abutment blocks and the forks or forklift frame, effectively preventing the abutment blocks from sliding, making the connection more secure, and thus improving the safety and stability of the entire lifting device.

[0037] See Figure 1 , Figure 2 The hook 108 can rotate around the hook ring 107, a design that greatly facilitates lifting operations. In actual lifting scenarios, the position and shape of goods vary. If the angle of the hook 108 remains fixed, it may not accurately connect the goods, or it may cause uneven force distribution and swaying after connection. However, the hook 108's ability to rotate freely around the hook ring 107 allows operators to flexibly adjust its angle according to the specific position and shape of the goods, ensuring precise connection. This not only ensures even force distribution and reduces swaying during lifting, but also improves the quality and efficiency of lifting operations, making the process smoother and safer.

[0038] See Figure 3 , Figure 4 The C-shaped frame 205 is clamped and fixed to the second abutment block 207 via the second tightening screw 206. This clamping and fixing structure is crucial for ensuring the stability of the connection between the lifting device and the forklift frame. During lifting operations, the C-shaped frame 205 bears the enormous tensile force generated by the goods. If the connection is not secure, the C-shaped frame 205 is prone to loosening or even falling off, which would directly lead to the falling of goods and cause serious safety accidents. By rotating the second tightening screw 206, the second abutment block 207 is tightly abutted against the forklift frame, forming a strong clamping force. This effectively prevents the C-shaped frame 205 from loosening or falling off during lifting, ensuring a safe and reliable connection between the lifting device and the forklift frame, and providing strong protection for lifting operations.

[0039] See Figure 1 , Figure 2The connection points between the traction cable 204 and the hanging ring 203 and C-shaped frame 205 are all equipped with anti-detachment structures. This design is a crucial element in ensuring lifting safety. During lifting, the traction cable 204 bears the entire weight of the cargo. If there were no anti-detachment structures at the connection points, the traction cable 204 could easily detach from the hanging ring 203 or C-shaped frame 205 under external impact, lifting sway, or aging of connecting parts, causing the cargo to fall, resulting in equipment damage and personal injury. The anti-detachment structures effectively prevent the traction cable 204 from detaching during lifting, and even in unexpected situations, ensure a stable connection between the traction cable 204 and the hanging ring 203 and C-shaped frame 205, greatly improving the safety and reliability of the lifting device.

[0040] The implementation principle of this embodiment is as follows: First, align the fork slots 102 on both sides of the mounting bracket 101 of the lifting device 1 with the forks of the off-road forklift and insert them. Then, rotate the first tightening screw 104 screwed to the bottom of the fork slot 102 so that the first abutment block 105 at the top of the first tightening screw 104 abuts tightly with the fork. The anti-slip structure on the surface of the first abutment block 105 can effectively increase the friction and prevent the fork from sliding relative to the fork slot 102 during the lifting process, ensuring that the connection between the lifting device 1 and the fork is stable and reliable, thus solving the problem of the traditional lifting device not being firmly connected to the fork.

[0041] Next, the fixing seat 201 of the stabilizing mechanism 2 is securely installed on the top of the mounting frame 101 using mounting bolts 103. The stabilizing mechanism 2 is made of high carbon steel, and the traction cable 204 is made of carbon steel, ensuring the strength and stability of the structure. A hanging ring 203 is hung on the hanging rod inside the connecting seat 202, and the traction cable 204 is connected to the back of the hanging ring 203. The C-shaped bracket 205 at one end of the traction cable 204 is hung on the forklift frame. Then, the second tightening screw 206 screwed to the outer surface of the C-shaped bracket 205 is rotated to tighten the second tightening screw. The second abutment block 207 at the end of 206 is in close contact with the forklift frame. The anti-slip structure on the surface of the second abutment block 207 also increases the friction, ensuring that the stabilizing mechanism 2 is firmly connected to the forklift frame. At the same time, the connection between the traction cable 204 and the hanging ring 203 and the C-shaped frame 205 is equipped with an anti-detachment structure to further prevent the traction cable 204 from falling off during the lifting process. This forms a complete stabilization and anti-fall system, which solves the problem of unstable cargo suspension and lack of effective anti-fall measures in existing lifting devices during the lifting process.

[0042] Finally, the goods to be lifted are connected to the hooks 108 on the hook rings 107 at the bottom of the mounting plate 106 at the bottom axis of the mounting frame 101 using ropes or the like. The hooks 108 can rotate around the hook rings 107, which makes it easy to adjust according to the lifting position and angle of the goods, making the lifting process more flexible and convenient. Through the above steps, the lifting device can safely and stably cooperate with the off-road forklift to complete the lifting operation of the goods.
