[0050] In this embodiment, when people need to carry the long workpiece 11, the bottom of the inelastic rubber band 61 is bent into a circle, and the circle formed by the bent inelastic rubber band 61 is put on the two ends of the long workpiece 11. Since the end of the inelastic rubber band 61 is fixed with a connecting block 65, a buckle 66 is rotatably provided at one end of the connecting block 65. By sleeved on the outside of the inelastic rubber band 61, a movable circle can be formed. By changing the position of the buckle 66 on the inelastic rubber band 61, the size of the circle formed by the inelastic rubber band 61 can be controlled. In order to prevent the inelastic rubber band 61 from falling off from the long workpiece 11, it is necessary to make the inelastic rubber band 61 contact with the surface of the long workpiece 11 more forcefully. In layman's terms, the inelastic rubber band 61 is used to hold the long workpiece 11 in place. The workpiece 11 is tightened. After the long workpiece 11 is sleeved with the inelastic rubber band 61, the lifting device assembly 1 is driven upward by the lifting machinery. When the lifting device assembly 1 moves upward to lift the long workpiece 11, the top of the inelastic rubber band 61 is subjected to force first. After the top of the inelastic rubber band 61 is subjected to force, it is affected by the weight of the long workpiece 11 itself, causing the bottom of the inelastic rubber band 61 to not move arbitrarily at first, but one end of the inelastic rubber band 61 applies an upward force to the moving pulley 32, thereby forcing the moving pulley 32 to move upward. After the moving pulley 32 moves upward, it drives the sliding block 23 to move upward together, so that the sliding block 23 overcomes the elastic force of the first compression spring 24 and moves together. At the same time, when the sliding block 23 moves, it will also drive the chain 51 and the elastic rod 41 to move. When the chain 51 is pulled, the chain 51 will drive the driving sprocket 72 to rotate. The rotation of the driving sprocket 72 will drive the connecting member 71 to rotate together. The rotation of the connecting member 71 will drive the rotating shaft 67 to rotate. The rotation of the rotating shaft 67 will drive the limiting wheel 73 and the driving gear 68 to rotate together. The rotation of the driving gear 68 will drive the teeth 62 to move. The movement of the teeth 62 will drive the inelastic rubber band 61 to move, so that the inelastic rubber band 61 tightens the long workpiece 11 after moving, thereby preventing the long workpiece 11 from falling off by increasing the friction between the inelastic rubber band 61 and the surface of the long workpiece 11. By setting the elastic rod 41, The elastic rod 41 can not only provide a certain central support for the first compression spring 24 to prevent the first compression spring 24 from unnecessary bending deformation, but also can store the redundant tail chain 51 to prevent the chain 51 from affecting the overall operation of the lifting device assembly 1. When the sliding block 23 moves upward, the sliding block 23 will drive the elastic rod 41 to move upward together, and after the elastic rod 41 moves upward, it will extend out of the sliding bracket 22 and then extend out of the outer side of the tension housing 21. The extended part of the elastic rod 41 will bend downward due to the tension of the chain 51. Because when the sliding block 23 moves upward, it will also drive the chain 51 to move, so that the end of the chain 51 moves downward to pull the elastic rod 41 to bend.It should be noted that, in the initial state, a part of the elastic rod 41 extends out of the outer side of the tension shell 21 and bends. The bent elastic rod 41 will be affected by its own elastic force to pull the tail of the chain 51, so that the tail of the chain 51 will not move around randomly, and the inelastic rubber band 61 on the upper side of the tension shell 21 will move relative to the tension shell 21. The relative movement is mainly achieved by the upward movement of the moving pulley 32, while the distance between the inelastic rubber band 61 on the lower side of the tension shell 21 and the tension shell 21 will basically not change, and there will only be a slight change caused by tightening the long workpiece 11. Therefore, when the inelastic rubber band 61 on the upper side of the tension shell 21 moves upward and moves relative to the tension shell 21 When the second magnet 93 is moved by the pull rope 94, the second magnet 93 will move away from the first magnet 85, so that the second magnet 93 will no longer generate magnetic force on the first magnet 85, so that the first magnet 85 will be driven to move by the transmission rod 84, and the transmission rod 84 will be driven to move by the sliding block 82, and the moving force of the sliding block 82 is provided by the second compression spring 83. The elastic force of the spring 83 is much smaller than the magnetic attraction between the first magnet 85 and the second magnet 93. After the sliding block 82 moves, it will drive the one-way rack 81 to move and engage with the limiting wheel 73 in one direction, so that the limiting wheel 73 can only rotate in the direction in which the inelastic rubber band 61 tightens the long workpiece 11, and cannot rotate in the opposite direction, thereby preventing the inelastic rubber band 61 from detaching from the long workpiece 11 during the lifting process. The elastic force of the first compression spring 24 does not need to be very large, and almost all of the gravity of the long workpiece 11 can indirectly compress the first compression spring 24 until the sliding pull block 23 moves upward to the position of the maximum stroke. When the long workpiece 11 is moved to the target position, the inelastic rubber band 61 needs to be tightened with the long workpiece 11. When the long workpiece 11 is separated, the long workpiece 11 is directly lowered by the lifting machinery so that the long workpiece 11 contacts the ground. After the long workpiece 11 contacts the ground, the long workpiece 11 will no longer exert a downward pulling force on the inelastic rubber band 61 at the upper end of the tension shell 21. As the lifting machinery drives the inelastic rubber band 61 at the upper end of the tension shell 21 to continue to descend, the inelastic rubber band 61 of this part will be retracted to the inner side of the tension shell 21. Specifically, under the influence of the elastic force of the first compression spring 24, the first compression spring 24 will push the sliding block 23 to move downward. The downward movement of the sliding block 23 will drive the moving pulley 32 to move downward. After the moving pulley 32 moves downward, the distance between the moving pulley 32 and the fixed pulley 31 will increase.The inelastic rubber band 61 wound in an S shape between the fixed pulley 31 and the movable pulley 32 will be received into the inner side of the tension housing 21 by increasing its length. When the sliding block 23 moves downward, the sliding block 23 will drive one end of the chain 51 connected thereto to move downward, and the sliding block 23 will also drive the elastic rod 41 to move downward, so that part of the elastic rod 41 will be retracted into the tension housing 21 again and then into the inner side of the sliding bracket 22. After the elastic rod 41 is retracted, it will drive the connector 42 and thus drive the other end of the chain 51 to move together, thereby preventing the chain 51 from being scattered. The movement of the chain 51 will drive the driving sprocket 72 to rotate in the opposite direction, and the driving sprocket 72 will drive the connecting piece 71 and thus drive the rotating shaft 67 to rotate in the opposite direction. When the workpiece 11 is lifted, the rotating shaft 67 drives the limiting wheel 73 and the driving gear 68 to rotate in the opposite direction. The reverse rotation of the driving gear 68 drives the teeth 62 and thus drives the inelastic rubber band 61 to move downward, so that the diameter of the circle formed by the lower side of the inelastic rubber band 61 becomes larger, so that the part of the circle formed by the inelastic rubber band 61 can be easily removed from the outside of the long workpiece 11, thereby achieving rapid automatic loosening. In this process, the one-way rack 81 will release the rotation restriction of the limiting wheel 73 in advance. Specifically, in the above-mentioned process in which the inelastic rubber band 61 at the upper end of the tension shell 21 continues to descend as the lifting machinery drives the inelastic rubber band 61 at the upper end of the tension shell 21 to first become loose. In the case of not being stretched straight, the inelastic rubber band 61 at the upper end of the tension shell 21 1 will become loose, the inelastic rubber band 61 on the upper end of the tension shell 21 will drive the connecting bracket 95 to move downward, and the sliding block 23 will not rotate due to the restriction of the chain 51 at this time. Since the chain 51 at this time will be indirectly restricted by the inability to reverse the limiting wheel 73, the driving sprocket 72 will also be unable to reverse, so that the chain 51 cannot move, and then the sliding block 23 cannot move downward at this time. However, before this step occurs, the inelastic rubber band 61 on the upper end of the tension shell 21 will become loose, so that the inelastic rubber band 61 on the upper end of the tension shell 21 will drive the connecting bracket 95 to move downward, and after the connecting bracket 95 moves downward, it will drive the pull rope 94 to move downward. Since the pull rope 94 has a certain The surplus amount, so in this process, it is just the opposite of the step in which the pull rope 94 drives the second magnet 93 to move upward. At this time, the connecting bracket 95 only drops a short distance, and the pull rope 94 drives the second magnet 93 to drop a sufficient distance, so that the second magnet 93 moves to the position closest to the first magnet 85. Under the influence of the magnetic force, the first magnet 85 will be affected by the magnetic force and move closer to the second magnet 93. The movement of the first magnet 85 will drive the transmission rod 84 and thus drive the sliding block 82 to move. The movement of the sliding block 82 will overcome the elastic force of the second compression spring 83 to move. The movement of the sliding block 82 will drive the one-way rack 81 to move and separate from the limiting wheel 73, thereby realizing the reverse rotation of the limiting wheel 73 through the separation of the one-way rack 81 and the limiting wheel 73. . ,

[0051] It should be noted that: mainly affected by the moving range of the sliding pull block 23, the lifting device assembly 1 can lift long workpieces 11 with cross-sectional sizes within a certain range.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
