Description

Technical Field

[0001] This invention relates to the field of cargo box frame processing technology, specifically to an automated lifting device for connecting cargo box frames. Background Technology

[0002] Cargo box frames are typically made of metal and include longitudinal beams, transverse beams, and other necessary connecting and reinforcing structures. Together, they form the framework of the cargo box, ensuring its strength and stability during transportation. In the initial stages of cargo box frame manufacturing, such as material cutting and welding preparation, lifting operations are usually not required. These stages mainly involve material pretreatment and preparation, such as cutting, grinding, and bending raw materials like steel plates and angle steel. These operations are generally performed on a horizontal workbench. As manufacturing progresses, the various components of the cargo box frame need to be assembled and welded together. In some cases, lifting operations may be necessary to adjust the components to suitable positions for welding or assembly. However, existing lifting devices often have fixed-size lifting platforms. When the cargo box frame to be lifted is long, the contact area between the lifting platform and the frame cannot be increased, affecting the stability of the lifting and potentially causing tilting due to unbalanced forces. This, in turn, affects the stability and quality of the connection. Summary of the Invention

[0015] According to the above technical solution, the second threaded rod passes through the inside of the lifting device body. The support platform and the lifting device body are respectively provided with moving grooves. The second threaded rod is slidably connected in the moving groove, which makes it easier to move the second threaded rod up and down more stably through the moving groove.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. The cargo box frame is connected to an automated lifting device. Through the designed lifting mechanism, when the cargo box frame needs to be lifted, the first and second fixed plates are raised and lowered by the action of the first pulley, the second pulley, the transmission belt, the first threaded rod, and the sliding rod. The first fixed plate then raises and lowers the lifting platform. Placing the cargo box frame on top of the lifting platform allows it to be raised and lowered by the platform. Simultaneously, the lifting platform can be extended by the action of the first gear, the first rotating rod, the extension frame, and the extension bracket, preventing the cargo box frame from becoming too long and affecting its stability on the top of the lifting platform. Qualitatively, the extension frame, along with the lifting platform, extension frame, and extension bracket, increases the contact area with the cargo box frame, ensuring the stability of the cargo box frame. Furthermore, the first gear drives the extension frame to rotate. When not in use, the extension frame is positioned inside the lifting platform, ensuring its normal operation. Simultaneously, the first cylinder, pressing block, and inclined block move the rack, causing it to rotate the gear and provide rotational power to the extension frame. Finally, under the action of the telescopic rod and the first spring, when the pressing block releases its pressure on the inclined block, the elasticity of the first spring causes the rack to reset, improving its performance.

[0018] 2. The cargo box frame is connected to an automated lifting device. Through a fixed mechanism, when the cargo box frame is placed on top of the lifting platform for connection work, the front and rear sides of the frame are clamped and fixed by the second cylinder, moving plate, second spring, rectangular plate, and clamping plate. This ensures the cargo box frame is stable on the top of the lifting platform, guaranteeing safety and stability during lifting. During clamping, the second spring, rectangular plate, and clamping plate, based on the shape of the cargo box frame, cause the clamping plate to compress the rectangular plate and second spring, further ensuring the stability of the cargo box frame. The system is designed to be qualitatively sound and can be fixed according to the shape of the cargo box frame, improving the fixing effect and avoiding instability caused by unevenness of the cargo box. When the cargo box frame needs to be fixed, the second cylinder drives the moving plate to move back and forth. When the moving plate moves, it will drive the clamping plate to move through the rectangular plate. When the inner side of the clamping plate comes into contact with the outer side of the cargo box frame, it will squeeze the clamping plate according to the shape of the cargo box frame, so that the clamping plate squeezes the rectangular plate and the second spring. Under the action of the clamping plate, the cargo box frame can be fixed and the stability of the cargo box frame can be guaranteed.

[0019] 3. The cargo box frame is connected to an automated lifting device. Through a set limiting mechanism, when the lifting device body is loading and unloading the cargo box frame, the moving wheels are limited by the second gear, third gear, second threaded rod, and limiting seat. This prevents the moving wheels from moving due to external factors during loading and unloading, ensuring a stable cargo box frame during connection and preventing wobbling. This improves the efficiency and quality of the connection. Furthermore, there are four sets of third gears, second threaded rods, and limiting seats, which further increases the contact area between the limiting seat and the ground, further ensuring stability. To ensure the stability of the moving wheel, when it is necessary to limit the moving wheel, the second servo motor drives the second gear fixedly connected to the third rotating rod to rotate. The second gear drives the third gear to rotate, which in turn drives the second threaded rod to rotate. The second threaded rod drives the limit seat to rise and fall, so that the bottom of the limit seat contacts the ground, thus limiting the moving wheel. When the second and third gears rotate, they will drive the first arc block and the second arc block to slide on the top of the lifting device body, respectively. Under the action of the first and second arc blocks, the rotation of the second and third gears can be made more stable. Attached Figure Description

[0035] This invention provides the following technical solutions:

[0036] Example 1

The first threaded rod 317 is threadedly connected to the movable groove. The top of the first rotating rod 3191 is rotatably connected to the top of the fixed frame 312. This allows the first threaded rod 317 to move more stably through the movable groove, thus limiting the movement of the first threaded rod 317.

[0041] Furthermore, the extension frame 3196 is rotatably connected to the inside of the lifting platform 313, and the fixing bolt 3199 passes through the inside of the extension frame 3196.

[0042] Example 2

[0043] See Figure 1-12Furthermore, based on Embodiment 1, the drive assembly 32 further includes a support plate 321, which is fixedly connected to the bottom of the lifting platform 313. A first cylinder 322 is fixedly connected to the rear side of the support plate 321, and a pressing block 323 is fixedly connected to the front side of the first cylinder 322. The top of the pressing block 323 is slidably connected to the bottom of the lifting platform 313.

[0044] Furthermore, a limiting groove is provided inside the limiting frame 325, the rack 326 is slidably connected in the limiting groove, and the wedge block 324 is slidably connected in the limiting frame 325, so that the rack 326 can be limited by the limiting groove, making the left and right movement of the rack 326 more stable.

[0045] Furthermore, the extrusion block 323 is trapezoidal in shape, with the front side of the extrusion block 323 in contact with the rear side of the inclined block 324, which facilitates the extrusion block 323 to extrude the inclined block 324, causing the inclined block 324 to drive the rack 326 to move.

[0046] Example 3

[0047] See Figure 1-12 Furthermore, based on Examples 1 and 2, the fixing mechanism 4 includes a mounting frame 42, which is fixedly connected to the rear side of the lifting platform 313. A second cylinder 41 is fixedly connected to the rear side of the mounting frame 42. A movable plate 43 is fixedly connected to the front side of the second cylinder 41. A second spring 44 is fixedly connected inside the movable plate 43. A rectangular plate 45 is fixedly connected to the front side of the second spring 44. The rectangular plate 45 is slidably connected inside the movable plate 43. A clamping plate 46 is fixedly connected to the front side of the rectangular plate 45.

[0048] Furthermore, the movable plate 43 has a sliding groove inside, and the rectangular plate 45 is slidably connected in the sliding groove, which makes it easier for the rectangular plate 45 to move more stably through the sliding groove.

[0049] Example 4

[0050] See Figure 1-12Based on Examples 1, 2, and 3, the limiting mechanism 6 further includes a second servo motor 61, which is fixedly connected to the top of the support platform 2. A third rotating rod 66 is fixedly connected to the bottom of the second servo motor 61. The bottom of the third rotating rod 66 is rotatably connected to the top of the lifting device body 1. A second gear 62 is fixedly connected to the periphery of the third rotating rod 66. A first arc-shaped block 67 is fixedly connected to the bottom of the second gear 62. The first arc-shaped block 67 is slidably connected to the top of the lifting device body 1. A third gear 64 meshes with the periphery of the second gear 62. A second arc-shaped block 68 is fixedly connected to the bottom of the third gear 64. The second arc-shaped block 68 is slidably connected to the top of the lifting device body 1. A second threaded rod 63 is internally threaded to the third gear 64. The top of the second threaded rod 63 is slidably connected to the inside of the support platform 2. A limiting seat 65 is fixedly connected to the bottom of the second threaded rod 63.

[0051] Furthermore, the second threaded rod 63 passes through the interior of the lifting device body 1. The support platform 2 and the lifting device body 1 are respectively provided with moving grooves. The second threaded rod 63 is slidably connected in the moving groove, which makes it easier to move the second threaded rod 63 up and down more stably through the moving groove.

[0052] In actual operation, when this device is used and the cargo box frame needs to be connected, the lifting device body 1 is first moved to the position where the cargo box frame needs to be connected via the moving wheels 5. Once the movement is complete, the second servo motor 61 drives the second gear 62, which is fixedly connected to the third rotating rod 66, to rotate. This causes the second gear 62 to drive the third gear 64 to rotate, which in turn drives the second threaded rod 63 to rotate. The second threaded rod 63 then drives the limiting seat 65 to rise and fall, bringing the bottom of the limiting seat 65 into contact with the ground. This limits the movement of the moving wheels 5, preventing them from moving due to external factors during loading and unloading, thus ensuring a stable state during the connection of the cargo box frame. When wobbling occurs, the rotation of the second gear 62 and the third gear 64 will respectively drive the first arc block 67 and the second arc block 68 to slide on the top of the lifting device body 1. Under the action of the first arc block 67 and the second arc block 68, the rotation of the second gear 62 and the third gear 64 can be made more stable. When the limit is completed, when the length of the cargo box frame is long, remove the fixing bolt 3199 so that the extension frame 31991 moves to the left within the extension frame 3196. When the movement is completed, thread the fixing bolt 3199 into the extension frame 3196 to limit the extension frame 31991. Then place the cargo box frame on the top of the lifting platform 313 so that the top of the lifting platform 313, the extension frame 3196 and the extension frame 31991 are aligned with the bottom of the cargo box frame. When the placement is complete, the second cylinder 41 drives the moving plate 43 to move back and forth. As the moving plate 43 moves, it drives the clamping plate 46 to move via the rectangular plate 45. When the inner side of the clamping plate 46 contacts the outer periphery of the cargo box frame, it presses against the clamping plate 46 according to the shape of the cargo box frame. This causes the clamping plate 46 to press against the rectangular plate 45 and the second spring 44, thus fixing the cargo box frame under the action of the clamping plate 46 and ensuring its stability. When lifting is required, the first servo motor 319 drives the first rotating rod 3191, which is fixedly connected to the first pulley 3192, to rotate. The first pulley 3192 then drives the second pulley 3194, which is connected to the inner side of the transmission belt 3193, to rotate. The second pulley 3194 drives the support block 3195 to rotate on top of the fixed cylinder 316. When the second pulley 3194 rotates, it drives the first threaded rod 317, the sliding rod 315, the first fixed plate 314, and the second fixed plate 318 to rise and fall. The first fixed plate 314 then drives the lifting platform 313 to rise and fall, lifting the cargo box frame to a suitable position for connection. The operation is convenient and highly stable. When it is necessary to retract the extension frame 3196 to the inside of the lifting platform 313, the first cylinder 322 drives the pressing block 323 to move forward, causing the pressing block 323 to press the inclined block 324. This causes the inclined block 324 to drive the rack 326 to move within the limiting frame 325. When the rack 326 moves...The first gear 3197, which meshes with the second rotating rod 3198, rotates, causing the extension frame 3196, which is fixedly connected to the second rotating rod 3198, to rotate. This rotates the extension frame 3196 to the inside of the lifting platform 313 and into a horizontal position. When the rack 326 moves, it causes the telescopic rod 328 and the first spring 3291 to deform. When the extension frame 3196 needs to rotate to the outside of the lifting platform 313, the first cylinder 322 moves the pressing block 323 rearward, releasing the pressure on the inclined block 324. This allows the first spring 3291 to reset, and the telescopic rod 328 then moves the first connecting block 327 and the rack 326 to the right, causing the extension frame 3196 to rotate to the outside of the lifting platform 313 and into a horizontal position.
