Description

Technical Field

[0001] The present invention relates to the technical field of swing-arm lifting devices, and particularly to a swing-arm lifting device. Background Art

[0002] In many fields such as industrial production, logistics transportation, and construction, the vertical and horizontal handling of materials is a basic operation. Traditional material handling methods, such as manual handling and simple crane lifting, have many limitations. Manual handling is inefficient, and for heavier materials, it is easy to cause physical injuries to workers; although ordinary crane lifting can handle heavier loads, it is often less flexible and difficult to precisely operate the placement of materials in some specific positions or complex environments. Moreover, these traditional methods are insufficient in adapting to the handling requirements of multi-variety and small-batch materials.

[0003] After retrieval, the applicant found that the Chinese patent disclosed "a swing-arm lifting device" with the publication (announcement) number "CN114212723B". This patent mainly drives the synchronous retraction and extension of two lifting belts by the rotation of a lifting motor, drives the synchronous lifting and lowering of two lifting accessories, and realizes the lifting of goods. The movement direction of the lifting accessories is restricted by the contact between the roller group and the guide groove, which can effectively prevent the swing-arm lifting fork carrying goods from shaking significantly and prevent situations such as jamming during the lifting and lowering of the lifting accessories from affecting the work efficiency. However, this patent cannot effectively clamp the product automatically, and when the lifting range of the lifting mechanism cannot meet the working requirements, it is also impossible to perform appropriate height adjustment on the clamping mechanism to meet the clamping requirements of the product. Then, during actual use, the product may not be clamped and fall, and the staff may need to use additional tools or equipment to adjust the product height to meet the clamping requirements. For this reason, we propose a swing-arm lifting device. Summary of the Invention

[0040] Embodiment 3:

[0041] Please refer to the appendix Figure 1 and the appendix Figure 10 and the appendix Figure 11 Based on Embodiment 2, it is further obtained that an angle adjustment assembly 6 is provided at the bottom of the frame 1. The angle adjustment assembly 6 includes a bottom plate 601 and a driven gear 608. A push plate 602 is fixedly connected to the back of the bottom plate 601.

[0042] The rotating rod 606 is rotatably connected to the inner wall of the support frame 604. A connecting column is provided at the top of the push plate 602, which is convenient for the staff to push the entire device. When the frame 1 rotates on the top of the fixing plate 609, the frame 1 will not touch the push plate 602.

[0043] Specifically, through the provided angle adjustment assembly 6, the staff can start the second motor 605. Through the meshing connection relationship between the driving gear 607 and the driven gear 608, and in cooperation with the fixing plate 609, during the process of the device lifting and clamping the product by swinging the arm, the staff can effectively adjust the direction of the device, and then can move the product to other directions, rather than being limited to a single direction. In this way, the flexibility of the product movement is increased, and the product can be moved in multiple directions.

[0044] Working principle of the present invention: The present invention is a swing-arm type lifting device. First, the staff adjusts the position of the swing-arm mechanism 2 by controlling the lifting mechanism 3. After the swing-arm mechanism 2 is adjusted to a proper position, the hydraulic rod 408 is then manipulated. The hydraulic rod 408 can push the connecting block 409 to move upward or downward. When the hydraulic rod 408 drives the connecting block 409 to move downward, the first fixed rod 410 will rotate at the inner wall of the connecting block 409, and at the same time, the second fixed rod 412 will rotate at the inner wall of the connecting member 416, thereby causing the two connecting arms 411 to expand and move in opposite directions. At this time, under the sliding connection action of the first groove 417 and the concave block 415, the connecting member 416 will also expand and move in opposite directions synchronously with the two connecting arms 411, thereby driving the two clamping plates 414 to unfold. After placing the product between the two clamping plates 414, the staff controls the hydraulic rod 408 to pull the connecting block 409 upward, and then clamps the product through the clamping plates 414. In some special cases, when it exceeds the action range of the lifting mechanism 3, the staff can start the first motor 402. The first motor 402 drives the worm 403 to rotate. The worm 403 drives the worm wheel 404 to rotate. The rotation of the worm wheel 404 will also cause the threaded rod 405 to rotate, thereby driving the fixture frame 407 to slide up and down on the outer walls of the threaded rod 405 and the limiting rod 406, and then appropriately adjust the height of the product clamped by the clamping plates 414. Secondly, during the operation of the device, the staff can start the vacuum cleaner 505. The vacuum cleaner 505 inhales the dust-containing gas generated during the operation of the device into the interior through the suction pipe 506, the suction plate 507 and the suction port 508, and then transmits the dust-containing gas to the filter 512 through the connecting pipe 511 for filtration. The filtered dust-containing gas is transported to the dust remover 514 through the air delivery pipe 513 for final purification treatment, and finally discharges the treated gas through the pipe at its top. Finally, when it is necessary to adjust the angle and direction of the device, the staff can drive the second motor 605. The second motor 605 drives the rotating rod 606 to rotate. The rotating rod 606 drives the driving gear 607 to rotate. The driving gear 607 drives the driven gear 608 to rotate. The driven gear 608 drives the fixed plate 609 to rotate, and drives the entire device to change the angle and direction through the fixed plate 609.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
