Description

Technical Field

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0029] like Figure 1 As shown, a lifting device for picking up and placing materials includes a mounting base 1, on which two long vertical beams 2 and two short vertical beams 3 are mounted. Several connecting beams 4 are fixedly connected between the two long vertical beams 2 and the two short vertical beams 3. Each of the two long vertical beams 2 is provided with a set of sliding components, and a material placement plate 5 is slidably connected to the sliding components. Each of the two long vertical beams 2 is provided with a set of upper limit components at the top. The top of the mounting base 1 is provided with two sets of lower limit components, which are symmetrically distributed along the center of the mounting base 1. A material conveying component is provided on the material placement plate 5, and an adjusting component for adjusting the lifting stroke is provided on the material conveying component.

[0030] The mounting base 1 provides support for the entire equipment. During use, the upper limit component is adjusted at the position of the long vertical beam 2 according to the material lifting stroke. Then, the lifting stroke of the material placement plate 5 is adjusted by the adjustment component to enable it to cooperate with various different equipment to pick up and place materials. In traditional solutions, if the material lifting stroke needs to be adjusted to adapt to other equipment to pick up and place materials, multiple parts inside the equipment need to be replaced. In this solution, the material lifting stroke can be changed by adjusting the component. After adjustment, the upper limit component limits the top of the material placement plate 5. Other equipment stores materials on the material placement plate 5 and drives the material placement plate 5 to descend through the material conveying component and the sliding component. The lower limit component limits the bottom of the material placement plate 5. After other equipment removes the materials, the material placement plate 5 rises again.

[0031] like Figure 1 and Figure 3 As shown, the sliding assembly includes a guide rail 6 disposed on the surface of the long vertical beam 2, and several sliders 7 are slidably connected on the guide rail 6. One side of the slider 7 is bolted to the material placement plate 5. The guide rail 6 provides support for the slider 7. Through the linear displacement of the slider 7 on the guide rail, the material placement plate 5 can be moved to complete the picking and placing of materials.

[0032] like Figure 2 and Figure 5 As shown, the upper limit assembly includes an upper abutment 8 and a first buffer 9, which are bolted to one side of the long vertical beam 2 by an upper mounting plate 10; the lower limit assembly includes a lower abutment 11 and a second buffer 12, which are bolted to the mounting base 1 by a lower mounting plate 13, and a pad is bolted to the lower abutment 11 at the end of the travel below the material placement plate 5, and the pad abuts against the bottom of the material placement plate 5.

[0033] The upper abutment 8 and the lower abutment 11 respectively limit the maximum stroke of the material placement plate 5 as it rises and falls. The first buffer 9 and the second buffer 12 effectively stop the object in balance during operation. This improves the efficiency of the machine, increases production capacity, extends the machine's lifespan, reduces maintenance costs, stabilizes the machine's operation, maintains product quality, makes the machine's operation safer, avoids accidents, and improves personnel efficiency. The pad can further enhance the buffering effect when the material placement plate 5 descends to the bottom.

[0034] like Figures 3 to 5As shown, the material conveying assembly includes a drive chain 14, with a drive sprocket 15 and a driven sprocket 16 wound around both ends of the drive chain 14. The drive chain 14 is also connected to a lifting connecting plate 17, which is bolted to the material placement plate 5. The drive sprocket 15 is rotatably connected to two long vertical beams 2 via a drive shaft 18. The driven sprocket 16 is rotatably connected to a driven mounting seat 19. A conveying crossbeam 20 is bolted to one side of the driven mounting seat 19. The two ends of the conveying crossbeam 20 are connected to the two long vertical beams 2. A lifting drive assembly is provided on the drive shaft 18. The lifting drive assembly includes a lifting chain 21, with a drive main wheel 22 and a drive driven wheel 23 wound around both ends of the lifting chain 21. The drive main wheel 22 is driven by a drive motor 24, which is bolted to the top of the mounting base 1 via a drive mounting plate 25. The drive driven wheel 23 is driven by the drive shaft 18.

[0035] The drive motor 24 serves as the driving source. The drive motor 24 drives the drive main wheel 22 to rotate through its output shaft. The drive main wheel 22 drives the lifting chain 21 and the driven wheel 23 to rotate. The rotation of the driven wheel 23 can drive the drive shaft 18 to rotate accordingly. The two ends of the drive shaft 18 are rotatably connected to the two long vertical beams 2 through bearings. The rotation of the drive shaft 18 can drive the drive sprocket 15 to rotate. The rotation of the drive sprocket 15 transmits power to the drive chain 14 and the driven sprocket 16. The rotation of the drive chain 14 can drive the lifting connecting plate 17 to perform linear displacement, thereby driving the material placement plate 5 to perform corresponding lifting. The above process forms a stable transmission path.

[0036] like Figure 6 As shown, the adjustment assembly includes an adjustment wheel 26, with an adjustment base 27 rotatably connected to both ends of the adjustment wheel 26. A pulley base 28 is provided at both ends of the adjustment base 27, and a fixed pulley 29 is rotatably connected to each pulley base 28. An adjustment beam 30 is fixed to the two pulley bases 28 and the adjustment base 27 by bolts to the adjustment base 27. The two ends of the adjustment beam 30 are connected to two connecting beams 4. Two first adjustment bolts 31 are provided on one side of the adjustment base 27, passing through the rotating shaft of the adjustment wheel 26. A first adjustment groove 32 for displacement of the adjustment wheel 26 is provided on the adjustment base 27. Two second adjustment bolts 33 are provided on the driven mounting base 19, passing through the rotating shaft of the driven sprocket 16. A second adjustment groove 34 for displacement of the driven sprocket 16 is provided on the driven mounting base 19.

[0037] By synchronously adjusting the height of the adjusting wheel 26 and the horizontal position of the driven sprocket 16, the wrap angle and length of the drive chain 14 are changed, thereby achieving continuous adjustment of the lifting stroke and chain tension. In actual use, different material handling scenarios may have different requirements for lifting height. This adjustment component can easily meet these diverse needs, improving the versatility and adaptability of the equipment. The adjustable positions of the adjusting wheel 26 and the driven sprocket 16 allow the chain to be re-tensioned by adjusting the positions of the first adjusting bolt 31 and the second adjusting bolt 33 after the equipment has been running for a period of time, ensuring that the drive chain 14 is always in a suitable tension state, thus guaranteeing the stability and reliability of the lifting of the material placement plate 5.

[0038] like Figure 5 As shown, a sensing beam 35 is provided at both the top and bottom of the long vertical beam 2, and a sensor 37 is fixed to the sensing beam 35 by bolts through a sensing mounting plate 36.

[0039] Sensors 37 are installed at the top and bottom of the long vertical beam 2 to monitor the position of the material placement plate 5 in real time. When the material placement plate 5 reaches the set upper or lower limit position, the sensor 37 can send a signal in time to stop the equipment, thereby achieving accurate positioning of the material placement plate 5 and avoiding damage to the equipment or materials due to excessive lifting or lowering.

[0040] Working principle: During use, according to the material lifting stroke, the upper abutment 8 and the first buffer 9 are installed to the corresponding positions on the top of the long vertical beam 2 via the upper mounting plate 10. The operator can change the position of the adjusting wheel 26 by turning the first adjusting bolt 31, which moves the adjusting wheel 26 in the first adjusting groove 32 of the adjusting base 27. At the same time, the operator can adjust the position of the driven sprocket 16 by turning the second adjusting bolt 33, which moves the driven sprocket 16 in the second adjusting groove 34 of the driven mounting base 19. By simultaneously adjusting the positions of the adjusting wheel 26 and the driven sprocket 16, the winding method and tension of the drive chain 14 are changed, thereby adjusting the lifting stroke range of the material placement plate 5. After adjustment, the upper abutment 8 and the first buffer 9 limit the top of the material placement plate 5. Other equipment stores materials on the material placement plate 5. The drive motor 24 drives the drive main wheel 22 to rotate. The drive main wheel 22 drives the drive driven wheel 23 to rotate via the lifting chain 21, which in turn drives the drive shaft 18 to rotate. The drive sprocket 15 on the drive shaft 18 rotates accordingly, driving the driven sprocket 16 to rotate via the drive chain 14. The lifting connecting plate 17 on the drive chain 14 drives the material placement plate 5 to slide up and down along the guide rail 6 on the long vertical beam 2. During the lifting and lowering of the material placement plate 5, the positions of the adjusting wheel 26 and the driven sprocket 16 remain relatively fixed to ensure that the drive chain 14 is always in a proper tension state, ensuring that the material placement plate 5 descends smoothly. The lower abutment 11 and the second buffer 12 limit the bottom of the material placement plate 5. After other equipment removes the material, the material placement plate 5 rises again. If the drive chain 14 is found to be loose after the equipment has been running for a period of time, the operator can adjust the positions of the adjusting wheel 26 and the driven sprocket 16 again through the first adjusting bolt 31 and the second adjusting bolt 33 to re-tension the drive chain 14 and ensure the normal operation of the equipment.
