Description
Technical Field
[0001] This utility model relates to the field of gear transportation technology, specifically to a gear mounting and lifting device. Background Technology
[0002] Gears, as common transmission components, are widely used in industrial fields such as engineering machinery, automobiles, and metallurgical equipment. During the production, processing, transportation, and assembly of gears, installation and handling operations are often required, especially for large gears, which are heavy and bulky. Manual handling is not only inefficient but also poses significant safety hazards.
[0003] In existing technologies, gear handling usually relies on ordinary lifting belts or wire ropes in conjunction with lifting equipment. However, since gears are mostly ring-shaped structures with smooth inner rings, they are prone to slippage, tilting, or even falling off during use. Utility Model Content

[0029] like Figure 1-3 As shown, this utility model embodiment proposes a gear mounting hanger, including: a fixing cylinder 10; and a fixing unit, including a plurality of fixing blocks 20 (such as...). Figure 2 As shown in the figure, this embodiment takes three fixing blocks 20 as an example) and an adjusting member 30. The fixing cylinder 10 has several mounting grooves that penetrate its side. Several fixing blocks 20 are slidably disposed in several mounting grooves. The adjusting member 30 is slidably disposed in the fixing cylinder 10 and abuts against several fixing blocks 20. When the adjusting member 30 moves along the axial direction of the fixing cylinder 10, it simultaneously drives several fixing blocks 20 to move along the radial direction of the fixing cylinder 10, so as to simultaneously abut against the inner ring of the gear body 80.
[0030] In this embodiment of the invention, when the gear body 80 needs to be hoisted, the operator first retracts the fixing block 20 of the gear mounting hoist, and then inserts the fixing cylinder 10 into the inner ring of the gear body 80. Subsequently, the operator uses the hoisting device or manual adjustment to drive the adjusting member 30 to slide along the axial direction of the fixing cylinder 10. At this time, the adjusting member 30 pushes multiple fixing blocks 20 to slide outward along the mounting groove, thereby opening synchronously in the radial direction, so that each fixing block 20 is evenly and firmly abutted against the inner wall of the inner ring of the gear body 80, thereby achieving a stable fit with the gear body 80, effectively preventing the gear body 80 from shaking or slipping during hoisting, improving the safety and reliability of the operation, and then the gear body 80 can be hoisted and transported. After the hoisting operation is completed, simply reverse the driving adjustment component 30 to move it back along the axial direction of the fixed cylinder 10, so that the fixed block 20 synchronously retracts radially and disengages from the inner ring of the gear body 80. The lifting device can then be easily removed from the gear body 80. The operation is simple and quick, and it is suitable for installation scenarios of various specifications of gear bodies 80.
[0031] Specifically, such as Figure 2-3 As shown in this embodiment of the invention, the adjusting member 30 includes a drive rod 31 slidably disposed along the axial direction of the fixed cylinder 10 and drive blocks 32 corresponding to a plurality of fixed blocks 20. The drive blocks 32 are disposed on the drive rod 31, and both the drive blocks 32 and the fixed blocks 20 have guide inclined surfaces, which slide against each other. In use, when the drive rod 31 moves along the axial direction of the fixed cylinder 10, the drive blocks 32 move together and slide relative to the guide inclined surfaces of the fixed blocks 20 through the guide inclined surfaces on the drive rod 31. Due to the existence of the inclined surface structure, the axial sliding force is converted into a radial component force, thereby pushing the fixed blocks 20 to gradually slide outward and open radially, achieving uniform tension on the inner ring of the gear body 80. After the hoisting operation is completed, the operator drives the drive rod 31 in the opposite direction to move it back axially. The drive blocks 32 slide accordingly, and the interaction of the guide inclined surfaces causes the fixed blocks 20 to contract synchronously radially, thereby releasing the contact with the gear body 80, and the lifting device can be easily removed.
[0032] Furthermore, the fixing block 20 is arc-shaped, and its outer arc surface matches the inner ring wall surface of the gear body 80, so that it can form surface contact or large-area adhesion when open, thereby improving contact stability. At the same time, each fixing block 20 is also provided with an anti-slip pad 21 on its outer surface. The anti-slip pad 21 can be made of materials with high friction coefficient and certain flexibility, such as rubber or polyurethane, which can effectively enhance the friction between the fixing block 20 and the inner ring of the gear and prevent slippage or loosening during hoisting.
[0033] Specifically, such as Figure 2As shown in this embodiment of the utility model, the top of the drive rod 31 is provided with a lifting ring 40. The lifting ring 40 can serve as a load-bearing connection point and can be directly connected to hoisting equipment such as a crane through a connecting rope to realize the overall suspension and transfer operation of the lifting device.
[0034] Based on the above solutions, such as Figure 3 As shown in this embodiment of the invention, the fixing block 20 is provided with a connecting block 50, and the fixing cylinder 10 is provided with a plurality of limiting grooves 11 corresponding to the plurality of connecting blocks 50. A spring 60 is provided within each limiting groove 11, and the connecting block 50 is engaged with the limiting groove 11 and abuts against the spring 60. When the adjusting member 30 drives the driving block 32 to move upward along the axial direction of the fixing cylinder 10, causing each fixing block 20 to expand radially outward, the connecting block 50 will compress the spring 60 within the limiting groove 11, causing the spring 60 to deform and apply a reaction force to the connecting block 50. With the restoring force of the spring 60, the connecting block 50 can automatically return the fixing block 20 to its mounting groove when the driving block 32 moves in the opposite direction, achieving automatic separation of the fixing block 20 from the inner ring of the gear body 80, facilitating the disassembly and repositioning of the lifting device.
[0035] In addition, a limiting rod 70 is provided in the limiting groove 11, the connecting block 50 is sleeved on the limiting rod 70, the limiting rod 70 is sleeved on the spring 60, and the spring 60 abuts between the connecting block 50 and the fixed cylinder 10. The limiting rod 70 effectively guides and limits the connecting block 50 and the spring 60, which not only ensures the accurate and stable movement trajectory of the fixed block 20, but also prevents the spring 60 from bending and deforming during compression and rebound, thus improving its service life.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
