Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , a high-efficiency lifting structure box device for a forklift, including a fixed frame 1, a lifting mechanism 2 is connected inside the fixed frame 1, the lifting mechanism 2 includes a flexible member 201, one end of the flexible member 201 is fixedly connected to a fixed plate 3, the fixed plate 3 is slidably connected to the front side of the fixed frame 1 through the flexible member 201, a cantilever assembly 4 is fixedly connected to the bottom of the front side of the fixed plate 3, clamping assemblies 5 are connected to the left and right sides of the top of the cantilever assembly 4, a box body 6 is limited and clamped between the two clamping assemblies 5, and a forklift fork 7 is fixedly connected to the bottom of the front side of the fixed frame 1;

[0024] The cantilever assembly 4 includes a connecting plate 401 and fork arms 402, the connecting plate 401 is fixedly connected to the front side of the fixed plate 3, fork arms 402 are fixedly connected to both the left and right ends of the connecting plate 401, fork arms 402, clamping assemblies 5 are connected to the tops of the two fork arms 402, and the two clamping assemblies 5 are arranged oppositely, and a box body 6 is arranged between the two fork arms 402.

[0025] Specifically, the lifting mechanism 2 drives the cantilever assembly 4 to move vertically, thereby realizing the lifting operation of the box body 6. During the lifting process, the flexible member 201 is made of a chain. With its good flexibility and load-bearing capacity, it ensures the smoothness and reliability of the lifting. The air cylinder 202 serves as the power source. Through the transmission of the control rod 203, it drives the piston rod 204 to reciprocate inside the air cylinder 202. The rotating wheel 205 at the top of the piston rod 204 meshes with the flexible member 201, converting the linear motion of the piston rod 204 into the winding or unwinding of the flexible member 201, thereby driving the fixed plate 3 and the entire cantilever assembly 4 to rise or fall.

[0026] Furthermore, the lifting mechanism 2 further includes an air cylinder 202, a control rod 203, a piston rod 204, and a rotating wheel 205. The air cylinder 202 is fixedly connected inside the fixed frame 1. The bottom end at the rear side of the air cylinder 202 is drivingly connected with the control rod 203. The top of the air cylinder 202 is movably connected with the piston rod 204. The top end of the piston rod 204 is rotatably connected with the rotating wheel 205. The rotating wheel 205 is meshingly connected with the flexible member 201. The other end of the flexible member 201 is fixedly connected to the top of the outer wall of the air cylinder 202. When the staff presses down the control rod 203 to start the air cylinder 202, the piston rod 204 reciprocates inside the air cylinder 202. As the piston rod 204 moves upward, the rotating wheel 205 at its top end will rotate accordingly and drive the flexible member 201 to gradually contract through the meshing relationship. During this process, the flexible member 201 serves as a transmission medium, converting the linear motion generated by the air cylinder 202 into the vertical lifting motion of the fixed plate 3, thereby driving the entire cantilever assembly 4 to rise smoothly.

[0027] Furthermore, the cantilever assembly 4 further includes a shear frame 403. The top of the shear frame 403 is movably connected with a fork arm 402. The bottom of the shear frame 403 is movably connected with a fork 7. While the shear frame 403 drives the cantilever assembly 4 to move vertically by the lifting mechanism 2, it provides additional support and stability, ensuring that no deformation occurs when carrying the box body 6, being able to effectively disperse and bear the weight from the box body 6 and the impact force generated during the lifting process. At the connection between the fork arm 402 and the shear frame 403, a precise hinge or bearing structure is adopted to achieve flexible and stable rotation, ensuring that the fork arm 402 can smoothly follow the vertical motion of the fixed plate 3 and the connecting plate 401 during the lifting process.

[0028] Furthermore, there are two forks 7. The two forks 7 are adapted to the two fork arms 402, enhancing the load-bearing capacity and stability of the device. The two forks 7 respectively correspond to the two fork arms 402, jointly supporting and fixing the box body 6, effectively preventing the box body 6 from shaking or shifting during transportation.

[0029] Further, the clamping assembly 5 includes a clamping plate 501, a clamping block 502 and a handle 503. The edge of the clamping plate 501 away from the fork arm 402 is hinged to the fork arm 402 through a hinge. A clamping block 502 is fixedly connected to the edge of the clamping plate 501 close to the box body 6. The clamping block 502 is adapted to the box body 6. The clamping plate 501 is snap-connected to the box body 6 through the clamping block 502. A handle 503 is fixedly connected to the top of the clamping plate 501. When the forklift needs to clamp and transport the box body 6, the lifting mechanism 2 is used to drive the cantilever assembly 4 to vertically slide and rise on the front side of the fixed frame 1, so that it is lifted to the top of the box body 6 and directly above the box body 6. The lifting mechanism 2 is used to drive the cantilever assembly 4 to descend until the clamping block 502 at the bottom of the clamping plate 501 contacts the top edge of the box body 6 and pushes the clamping plate 501, causing the clamping plate 501 to rotate around the hinge point. When the top edge of the box body 6 moves above the fork arm 402, the clamping plate 501 resets under the action of gravity, and the clamping block 502 just fits into the edge groove of the box body 6 or closely adheres to its surface, realizing the stable clamping of the box body 6. And because the two clamping assemblies 5 are arranged oppositely, they can clamp the box body 6 from both sides at the same time, ensuring the stability and safety of the box body 6 during transportation.

[0030] Further, a traveling wheel 8 is fixedly installed on the front side of the bottom of the fork 7, and a traveling wheel 8 is also fixedly installed on the bottom of the rear side of the fixed frame 1. A pull rod 9 is fixedly connected to the middle of the rear wall of the fixed frame 1. The staff can easily hold the pull rod 9 and control the movement direction of the entire forklift high-efficiency lifting structure box device by applying a pushing force or a pulling force. At the same time, the flexible rotation of the traveling wheel 8 ensures the smoothness of the device during movement.

[0031] Working principle of the utility model: During use, the device is moved as a whole by holding the pull rod 9, and flexible and stable displacement is achieved by means of the traveling wheels 8 installed on the front and rear sides of the bottom until the device approaches the box body 6 to be transported. Once the device is accurately positioned, the staff can start operating the lifting mechanism 2. By pressing down the control rod 203, the cylinder 202 is activated, and the piston rod 204 in the cylinder 202 immediately starts to move upward. During this process, the rotating wheel 205 at the top of the piston rod 204 meshes tightly with the flexible member 201. As the piston rod 204 rises, the rotating wheel 205 drives the flexible member 201 to gradually contract, thereby pulling the fixed plate 3 and the connected cantilever assembly 4 to rise as a whole. The fork arms 402 and the shear frame 403 in the cantilever assembly 4 work together to ensure that the lifting process is both stable and reliable. When the cantilever assembly 4 rises to an appropriate position above the box body 6, the lifting mechanism 2 is continuously operated to slowly lower the cantilever assembly 4 until the block 502 at the bottom of the clamping plate 501 gently touches the top edge of the box body 6. As the cantilever assembly 4 further descends, the block 502 will push the clamping plate 501 to rotate around the hinge point. When the edge of the box body 6 completely enters the space between the clamping plate 501 and the fork arm 402, the clamping plate 501 automatically resets under the action of gravity, and the block 502 tightly fits into the edge groove of the box body 6 or closely adheres to its surface, thereby achieving firm clamping of the box body 6. Finally, the staff holds the pull rod 9 again and pushes or pulls the device to move the forklift high-efficiency lifting structure box device with the box body 6 to the designated position.
