Description

Technical Field

[0001] The present invention relates to a material lifting device. Background Art

[0002] In actual processing, the shape of the material is determined by the product. Due to the particularity of some materials themselves, it is extremely difficult to automatically feed them using automated equipment. For example, annular discs. Moreover, the clamping height of some feeding devices is limited. The feeding device can only clamp the material after the material is lifted to a certain height. Traditional material lifting devices can only change the height of the material by lifting the placement table after the staff stacks a large amount of materials orderly on its placement table. This means that the staff needs to first use a special handling device to transport a large amount of materials to the vicinity of the material lifting device, and then place the large amount of materials on the placement table of the material lifting device one by one, resulting in multiple handling operations, thus wasting a lot of time on the handling work of the materials and seriously affecting the overall lifting efficiency of the materials.

A rear upright column bottom plate 546 is provided on the lower surface of the rear upright column base 502, and the rear upright column base 502 is located at the center of the upper surface of the rear upright column bottom plate 546.

[0035] Drag chain brackets 547 are provided on the front side wall of the front upright column 503 and the rear side wall of the rear upright column 504. The drag chain bracket 547 is connected to the lifting bottom plate 524 on its front side through a drag chain 548.

[0036] The usage method of the present invention is as follows:

[0037] Before the feeding of materials, the hook 538 of the trolley 534 is not actually suspended on the suspension arm 539 of the translation seat 532. At this time, the trolley 534, as an independent entity, is on the ground, facilitating the concentration of a large number of materials 7 using the trolley 534. Since the support frame 537 on the lower left side wall of the lower end of the material 7 is lower than the lower surface of the wheel 536, when the trolley 534 is stationary, the support frame 537 contacts the ground, while the wheel 536 is suspended above the ground, ensuring the stability of the trolley 534 when it is stationary. At this time, the annular material 7 can be sleeved on the hanging rod 535 on the left side of the trolley 534. As the staff loosens the annular material 7 sleeved outside the hanging rod 535, the annular material 7 will fall under its own gravity at this moment, and the hanging rod 535 will prevent the annular material 7 from falling by restricting the inner wall of the annular material 7, making the annular material 7 in a state of being suspended on the hanging rod 535. After each hanging rod 535 is hung with the actual required number of annular materials 7, the upper end of the trolley can be pushed downward to the right using the handrail at the upper end of the trolley 534. At this time, the lower end of the trolley 534 drives the support frame 537 to lift and leave the ground, and the wheel 536 starts to directly contact the ground. Then, the wheel 536 can be used to move the trolley 534, thereby realizing the movement of the annular material 7. When the trolley 534 moves between the translation seats 532 on the front and back sides, the suspension arm 539 is just below the hook 538 at this moment, and then the height of the suspension arm 539 can be adjusted.

[0038] When it is necessary to adjust the height of the suspension arm 539, the servo motor can be started. At this time, the motor shaft of the servo motor 513 will drive the worm and gear reducer 512 to operate, and the output shaft 515 of the worm and gear reducer 512 will rotate accordingly, thereby realizing the rotation driven by the upper sprocket 517. The upper sprocket 517 and the lower sprocket 520 are connected by a roller chain 523. When the upper sprocket 517 rotates, the roller chain 523 rotates and conveys synchronously. The existence of the front notch 508, the upper pipe orifice of the front column 503, and the rotating orifice 518 at the lower part of the front column 503 can ensure that the roller chain 523 on the front side can be connected to the upper and lower ends of the lifting bottom plate 524 on the front side while matching with the upper sprocket 517 and the lower sprocket 520. The existence of the rear notch 509, the upper pipe orifice of the rear column 504, and the rotating orifice 518 at the lower part of the rear column 504 can ensure that the roller chain 523 on the rear side can be connected to the upper and lower ends of the lifting bottom plate 524 on the front side while matching with the upper sprocket 517 and the lower sprocket 520, thus ensuring the smoothness of the rotation and conveyance of the roller chains 523 on the front and back sides. When the roller chain 523 rotates and conveys, the lifting bottom plate 524 will move up and down along the track of the first guide rail 527.

[0039] When the lifting bottom plate 524 moves upward, the suspension arm 539 on the translation seat 532 moves upward synchronously. At this time, the suspension arm 539 continuously moves upward and approaches the hook 538 above it. When the suspension arm 539 moves upward to a position closer to the hook 538, the fourth cylinder 531 can be activated. At this time, the piston rod of the fourth cylinder 531 will drive the translation seat 532 to move stably along the track of the second guide rail 529, and the suspension arm 539 moves synchronously. At this time, the card slot 540 on the suspension arm 539 finally moves to directly below the hook 538. Then, the fourth cylinder 531 can be closed, and then the servo motor 513 is activated again to make the roller chain 523 rotate and convey again, realizing the upward movement of the suspension arm 539 again, so that the hook 538 is clamped into the card slot 540, ensuring the stability between the hook 538 and the suspension arm 539. At this moment, the suspension arm 539 continues to move upward, driving the hook 538 to move upward, thereby realizing the upward movement of the trolley 534. When the trolley 534 drives a large number of annular materials 7 upward to the actual required height, the roller chain 523 stops conveying. When the trolley 534 suspends a large number of materials at the actual required height, it is convenient for the feeding equipment to clamp the annular materials 7 suspended on the hanging rod 535, thus completing the feeding of the annular materials.

[0040] As can be seen from the above, the present invention can directly collect a large number of materials through the trolley 534 and then carry them. After the trolley 534 transports a large number of materials between the translation seats 532 on the front and back sides, the hook 538 can be lifted by the suspension arm 539 on the translation seat 532, so as to directly lift the entire trolley 534. At this time, a large number of materials 7 on the trolley 534 are synchronously lifted. When the materials 7 reach the actual required height, they can be easily clamped by the feeding equipment. During the entire lifting process, after placing a large number of materials 7 on the trolley 534, there is no need to carry the materials 7 again, effectively saving a lot of time, thereby effectively improving the overall lifting efficiency of the materials 7.

[0041] A screw hole 541 is provided at the center of the upper end and the center of the lower end of the lifting bottom plate 524. The lower end of the upper hanging ring 525 can be screwed into the screw hole 541 at the center of the upper end of the lifting bottom plate 524, and the upper end of the lower hanging ring 526 can be screwed into the screw hole 541 at the center of the lower end of the lifting bottom plate 524. This fixing method is convenient for the disassembly and assembly of the upper hanging ring 525 and the lower hanging ring 526, thereby facilitating the replacement of the upper hanging ring 525 and the lower hanging ring 526.

[0042] An annular card slot 540 is provided on the outer wall of the end of the suspension arm 539, and the hook is clamped in the card slot 540. The existence of the card slot 540 can effectively limit the hook 538 in the card slot 540, effectively ensuring the stability when the suspension arm 539 lifts the hook 538, and thus ensuring the stability when the materials 7 on the trolley 534 move up and down.

[0043] The lower surface of the hook 538 is provided with a limiting groove 542. The upper side wall of the limiting groove 542 is provided with an arc surface 543 that fits against the bottom of the clamping groove 540. The depth of the limiting groove 542 is greater than the inner diameter of the clamping groove 540. The arc surface 543 can be perfectly fitted with the clamping groove 540, ensuring the stability of the hook 538 in the clamping groove 540 to the greatest extent.

[0044] The upper end of the trolley 534 slopes to the right, and the hanging rod 535 is perpendicular to the trolley 534. At this time, the left end of the hanging rod 535 tilts upward. The slope formed by the hanging rod 535 itself can make the material 7 automatically slide and approach the left side wall of the trolley 534, achieving the anti-detachment effect and avoiding the situation that the material 7 is likely to slide off the hanging rod 535 due to the hanging rod 535 being too straight.

[0045] The lower surface of the front column base 501 is provided with a front column bottom plate 545. The front column base 501 is located at the center of the upper surface of the front column bottom plate 545. The lower surface of the rear column base 502 is provided with a rear column bottom plate 546. The rear column base 502 is located at the center of the upper surface of the rear column bottom plate 546. The existence of the front column bottom plate 545 can effectively increase the bearing area of the front column base 501, thereby further ensuring the stability and bearing effect of the front column 503. The existence of the rear column bottom plate 546 can effectively increase the bearing area of the rear column base 502, thereby further ensuring the stability and bearing effect of the rear column 504.

[0046] The front side wall of the front column 503 and the rear side wall of the rear column 504 are both provided with a drag chain support 547. The drag chain support 547 is connected to the lifting bottom plate 524 in front of it through a drag chain 548. The existence of the drag chain 548 can play a traction effect when the lifting bottom plate 524 moves up and down, ensuring the stability of the lifting bottom plate 524 when it moves up and down, and at the same time can play a noise reduction effect.
