Description

Technical Field

[0001] This utility model relates to an integrated rope winding structure and a material handling machine, belonging to the field of material handling machine technology. Background Technology

[0002] A material handling machine is a mechanical wire rope conveying device that uses a hoist as a fixed device. It is suitable for various continuous lifting operations and can also be used as a wire rope storage device. The device includes a power unit, rope winding components, rope laying components, rope feeding protection, rope retraction protection, and hanging points, all integrated inside the frame.

[0003] In existing rope winding components, the rope reels are mostly connected by welding. Welded reels often suffer from insufficient roundness, which can cause vibration when the reel rotates to wind up the wire rope. Furthermore, it's difficult to ensure coaxiality of the components on the reel. As the wire rope is continuously wound onto the reel, the weight increases, amplifying the vibration and making some parts prone to damage. In addition, current technologies often use dry friction for the rope reels. While grease is applied to the friction plates during installation, this only provides short-term smoothness. Regular disassembly and reapplication of new lubricant are required, reducing work efficiency and wasting significant manpower and time. Utility Model Content

[0004] This utility model provides an integrated rope winding structure and material handling machine, which solves the problems in the prior art where the rope coil roundness is insufficient, vibration occurs during rope winding, and the vibration increases with the weight, leading to damage to some parts. It also addresses the need for workers to regularly disassemble and apply new lubricating oil, which reduces work efficiency and wastes a lot of manpower and time.

[0005] This utility model is achieved through the following technical solution:

[0006] Firstly, this utility model provides an integrated rope winding structure, including...

[0007] axis;

[0008] A first flange is fitted around the outer circumference of the shaft and is rotatably connected to the shaft.

[0009] The second flange is sleeved on the outer circumference of the shaft and fixedly connected to the shaft. The second flange is rotatably connected to the first flange.

[0010] A connecting disc, which is sleeved on the outer circumference of the shaft and rotatably connected to the shaft;

[0011] A bushing, which is fitted around the outer periphery of the shaft;

[0012] An oil inlet and an oil plug are provided, wherein the oil inlet is located on the first flange and the oil plug is installed on the oil inlet.

[0013] In one embodiment of this utility model, a one-way bearing is included, and the second flange and the shaft are fixedly connected by the one-way bearing.

[0014] In one embodiment of this utility model, a box cover is included. The connecting plate has multiple holes on the side near the box cover. The connecting plate is fitted onto the bolts of the box cover through the holes, so that the connecting plate is connected to the box cover.

[0015] In one embodiment of this utility model, a first friction plate and a first gasket are provided between the first flange and the second flange. The first gasket is symmetrically arranged on both sides of the first friction plate and abuts against the first flange and the second flange respectively.

[0016] In one embodiment of this utility model, a second friction plate and a second gasket are provided between the connecting plate and the second flange. The second gasket is symmetrically arranged on both sides of the second friction plate and abuts against the connecting plate and the second flange respectively.

[0017] In one embodiment of this utility model, the second gasket is provided with a cylinder and an elastic body. The elastic body is sleeved on the outer periphery of the cylinder, and its two ends abut against the second flange and the second gasket, respectively. This allows for the application of a clamping force to the second friction plate. The cylinder serves to fix the elastic body and provide a direction for the force application.

[0018] In one embodiment of this utility model, a first seal, a second seal, a third seal, and a fourth seal are included. The first seal is located between the shaft and the first flange, the second seal is located between the first flange and the second flange, the third seal is located between the second flange and the connecting plate, and the fourth seal is located between the shaft and the connecting plate. The first, second, third, and fourth seals form a closed chamber structure between the shaft and the first flange. This structure can be used to store lubricating oil, maintaining lubrication for a longer period. Furthermore, it eliminates the need for disassembly and reapplying of new lubricating oil; simply opening the oil plug and injecting lubricating oil through the oil inlet improves work efficiency and saves significant manpower and time.

[0019] In one embodiment of this utility model, a first connector and a second connector are included. The two sides of the first connector abut against the first flange and the shaft, respectively, and the two sides of the second connector abut against the second flange and the connecting plate, respectively.

[0020] In one embodiment of this utility model, it includes a rope coil edge plate and a support rod. There are two rope coil edge plates, which are symmetrically arranged on both sides of the first flange and connected to the first flange through the support rod.

[0034] like Figures 1 to 5As shown, this application provides an integrated rope winding structure. This integrated structure facilitates disassembly and subsequent maintenance, improves work efficiency, and reduces the waste of manpower and time. The rope winding structure is sleeved on the outer periphery of a shaft 10. One end of the shaft 10 is connected to a drive structure. The drive structure drives the rope winding structure to rotate via the shaft 10, thereby performing the rope winding action. The rope winding structure includes two rope coil edge plates 1, which are arranged parallel to each other and have their centers on the same axis. The rope coil edge plates 1 are used to limit the width of the wound wire rope. Multiple support rods 2 are provided between the two rope coil edge plates 1, evenly distributed on the rope coil edge plates 1, providing support for the two rope coil edge plates 1 and preventing deformation of the rope coil edge plates 1.

[0035] In some embodiments, the rope winding structure further includes a first flange 5, a second flange 6, a first seal 4, and a first connector 3. The first connector 3 is sleeved on the outer periphery of the shaft 10, and the first seal 4 is also sleeved on the outer periphery of the shaft 10. The first connector 3 is symmetrically arranged on both sides of the first seal 4. The first flange 5 is a tapered flange, sleeved on the outer periphery of the first connector 3 and the first seal 4. Two rope coil edge plates 1 are sleeved on the outer periphery of the first flange 5 and connected to the first flange 5 via a support rod 2. The two ends of the support rod 2 are threaded, and the distance between the two rope coil edge plates 1 can be adjusted by the threads. The second flange 6 is a swivel flange, sleeved on the outer periphery of the shaft 10. A one-way bearing 9 and a retaining ring 19 are provided between the second flange 6 and the shaft 10. Both the one-way bearing 9 and the retaining ring 19 are sleeved on the outer periphery of the shaft 10, and the retaining ring 19 is nested in the second flange 6 to prevent the one-way bearing 9 from sliding. The second flange 6 can be connected to the one-way bearing 9 by key 26, and the shaft 10 can also be connected to the one-way bearing 9 by key 26. The shaft 10 drives the second flange 6 to rotate through the one-way bearing 9.

[0036] In some embodiments, the second flange 6 is nested within the first flange 5. A first friction plate 12, a first gasket 13, and a second seal 18 are disposed between the first flange 5 and the second flange 6. The first friction plate 12 is sleeved on the outside of the second flange 6, and the first gasket 13 is symmetrically disposed on both sides of the first friction plate 12. The first gasket 13 is used to improve the wear resistance between the first flange 5 and the second flange 6. The second seal 18 is located on the side of the first friction plate 12 away from the first connector 3. The second seal 18 cooperates with the first seal 4 to form a closed chamber between the first flange 5 and the second flange 6, which can be used to store lubricating oil.

[0037] In some embodiments, the rope winding structure further includes a connecting disc 8, located on the side of the second flange 6 opposite to the first flange 5. The connecting disc 8 is nested within the second flange 6. A second connecting member 21, a second friction plate 24, a second gasket 25, and a third sealing member 22 are disposed between the connecting disc 8 and the second flange 6. The second connecting member 21 is sleeved on the outer periphery of the connecting disc 8 and connects to both the connecting disc 8 and the second flange 6. The second friction plate 24, the second gasket 25, and the third sealing member 22 are all sleeved on the outer periphery of the connecting disc 8 and located on the side of the second connecting member 21 opposite to the one-way bearing 9. The second gasket 25 is symmetrically arranged on both sides of the second friction plate 24 to increase the wear resistance of the second flange 6 and the connecting disc 8. The third sealing member 22 is installed on the side of the second friction plate 24 opposite to the second connecting member 21, forming a seal between the second flange 6 and the connecting disc 8. A fourth seal 23 is also provided on the side of the connecting plate 8 and the shaft 10 near the cover 20. The fourth seal 23 is sleeved on the shaft 10 and abuts against the connecting plate 8, so that a sealed chamber is formed between the shaft 10 and the first flange 5, which can be used to store lubricating oil.

[0038] In some embodiments, the connecting disc 8 has a circular hole on the side near the cover 20. The connecting disc 8 fits onto the bolts of the cover 20 through the circular hole, preventing the connecting disc 8 from rotating relative to the cover 20. The number of circular holes on the connecting disc 8 is adapted to the cover 20. Simultaneously, this nesting method allows for easy and quick removal of the entire rope-gathering structure when it needs to be disassembled for maintenance, as the connecting disc 8 and the cover 20 are not bolted together. This saves time spent removing bolts between the connecting disc 8 and the cover 20, improving worker efficiency.

[0039] In some embodiments, a bushing 7 is fitted on the shaft 10. The bushing 7 is located between the cover 20 and the one-way bearing 9. The bushing 7 is made of copper, which can improve the coaxiality of the entire rope winding structure and avoid damage to parts caused by excessive vibration of the rope reel during the rope winding process.

[0040] In some embodiments, an oil inlet 16 and an oil plug 17 are provided on one side of the first flange 5. The oil inlet 16 communicates with the sealed chamber formed between the shaft 10 and the first flange 5. The oil plug 17 is used to seal the oil inlet 16, allowing lubricating oil to be injected into the sealed chamber to lubricate the two friction plates. Using oil injection instead of applying grease for friction plate friction maintains lubrication for a longer period and eliminates the need for disassembly and reapplication of new lubricating oil. Simply opening the oil plug 17 and injecting lubricating oil through the oil inlet 16 improves work efficiency and saves significant manpower and time.

[0041] In some embodiments, a locking member 11 is provided at one end of the shaft 10 away from the cover 20. A butterfly valve is provided between the locking member 11 and the first connecting member 3. The locking member 11 is a locking nut, which can tighten the rope winding structure. The torque of the rope reel can be adjusted by adjusting the locking member 11.

[0042] In some embodiments, a cylinder 14 is provided on the side of the second gasket 25 near the second flange 6, and an elastic body 15 is sleeved on the cylinder 14. The two ends of the elastic body 15 abut against the second gasket 25 and the second flange 6 respectively, which can apply a clamping force to the second friction plate 24. The cylinder 14 is used to fix the elastic body 15 and provide the direction of force application for the elastic body 15.

[0043] Optionally, the elastomer 15 is a spring, and both the first connector 3 and the second connector 21 are deep groove ball bearings.

[0044] Optionally, the first seal 4 is a rubber sealing ring, and the second seal 18, the third seal 22 and the fourth seal 23 are rotary lip seals.

[0045] Furthermore, this application also provides a material handling machine that uses the aforementioned integrated rope winding structure. This integrated rope winding structure is connected to the material handling machine via shaft 10 and works in conjunction with other structures to complete the rope winding and unwinding operations. Because the material handling machine uses any of the aforementioned integrated rope winding structures, it possesses the advantages described above.

[0046] The working principle of this utility model is as follows: The rope winding structure is installed on shaft 10. Shaft 10 drives the second flange 6 to rotate via a one-way bearing 9. The second flange 6 drives the first flange 5 to rotate via a first friction plate 12, winding the wire rope between the two rope reel edge plates 1. During rope unwinding, the wire rope pulls the first flange 5 to rotate due to tension. The friction generated by the friction plate in the rope winding structure controls the first flange 5 to rotate at a certain speed for rope unwinding. By setting a bushing 7 on shaft 10, the coaxiality of the entire rope winding structure can be improved, avoiding damage to components caused by excessive vibration of the rope reel during rope winding. By setting an oil inlet 16 and an oil plug 17 on one side of the first flange 5, lubricating oil can be injected into the closed chamber through the oil inlet 16 to lubricate the two friction plates. This maintains lubrication for a longer period of time, and there is no need to disassemble and apply new lubricating oil. Simply open the oil plug 17 and inject lubricating oil through the oil inlet 16, improving work efficiency and saving a lot of manpower and time. Moreover, the entire rope winding structure is an integrated structure, which can be disassembled as a whole if there is a problem, making it convenient for later installation and maintenance.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.

[0049] This document uses specific embodiments to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
