Description

Technical Field

[0001] The present invention relates to the technical field of walking wheels, and specifically to a walking wheel with a high load-bearing capacity structure. Background Art

[0002] As an important part of mechanical equipment, walking wheels are widely used in various scenarios, such as industrial production, logistics transportation, construction, etc. With the acceleration of the industrialization process and the development of mechanical equipment towards large-scale and heavy-duty, higher requirements are put forward for the load-bearing capacity of walking wheels.

[0003] The limitations in the design and manufacturing of traditional walking wheels lead to problems such as deformation and damage of walking wheels when bearing heavy loads due to the stress caused by the combination of heavy pressure and large torque when meeting the requirements of modern heavy machinery and equipment, resulting in poor operating stability of the equipment and prone to safety accidents. Therefore, a walking wheel with a high load-bearing capacity structure is needed. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a walking wheel with a high load-bearing capacity structure, which solves the problems such as deformation and damage that are prone to occur when traditional walking wheels meet the requirements of modern heavy machinery and equipment.

The front end of the anti-torsion high-load-bearing shaft is connected to a wheel body joint through bolts;

[0008] An inner hub, on the outer wall of which a tire body is sleeved. A connecting piece is fixedly connected to the inner circumference of the inner hub. A fitting cover is arranged on the front side of the connecting piece. Both the fitting cover and the connecting piece are connected to the front side of an external housing through bolts. A limiting component is arranged between the fitting cover and a butting head to prevent the tire body from shifting and falling off the inner hub under the action of large torque and heavy pressure;

[0009] An external housing, which is connected to the rear side of the protective housing through bolts so that the walking wheel can be loaded on corresponding equipment. A plugging sleeve is rotatably connected to the middle end of the external housing. A transmission head is sleeved on the front end of the plugging sleeve, and the transmission head is connected to the rear end of the anti-torsion high-load-bearing shaft so that the driving shaft of the equipment can be plugged into the inside of the plugging sleeve to drive the walking wheel to move. A pressurizing component is installed on the inner wall of the plugging sleeve to pressurize the driving shaft after it is plugged into the inside of the plugging sleeve, further stabilizing the plugging stability of the driving shaft.

[0010] Preferably, the torsion-resistant high-load bearing shaft includes a planetary gear installed at the rear end of the inner wall of the protective housing. The rear input end of the planetary gear is fixedly connected to a transmission head. A stabilizing planetary gear is installed at the front output end of the planetary gear. The rear side of the external housing is connected to the stabilizing planetary gear.

[0011] Preferably, the stabilizing planetary gear includes a rotating seat fixedly connected to the front driving end of the planetary gear. A stabilizing frame is rotatably connected to the outer periphery of the front side of the rotating seat. A plurality of limiting grooves are provided on the outer periphery of the front side of the stabilizing frame. A surrounding gear is rotatably connected inside the limiting groove. A tooth column is fixedly connected to the middle of the front side of the rotating seat. The front end of the tooth column penetrates through the middle of the stabilizing frame and meshes with a plurality of the surrounding gears. The outer walls of the plurality of surrounding gears are meshed with a tooth ring. The outer wall of the tooth ring is fixedly connected to the inner wall of the protective housing. The rear side of the wheel body joint is connected to the front side of the stabilizing frame by bolts.

[0012] Preferably, the outer peripheries of both the wheel body joint and the stabilizing frame are connected to the inner wall of the protective housing through bearings.

[0013] Preferably, the limiting component includes a plurality of limiting members slidably connected to the outer periphery of the inner hub. The inner periphery of the tire body is sleeved on the outer periphery of the limiting members. An abutting inclined groove is provided on the inner periphery of the limiting members. A plurality of abutting heads are fixedly connected to the outer periphery of the fitting cover. An abutting inclined surface is provided at the rear end of the abutting head. The abutting inclined surface abuts against the abutting inclined groove.

[0014] Preferably, the outer peripheral cross-sectional shape of the limiting member is a special-shaped structure. A special-shaped ring groove is provided on the inner periphery of the tire body. The outer peripheral cross-sectional shape of the limiting member fits the cross-sectional shape of the special-shaped ring groove.

[0015] Preferably, the pressing component includes threaded grooves provided at the left and right ends of the plug-in sleeve. A pressing member is slidably connected to one end inside the threaded groove. Abutting bolts are threadedly connected to the other end of the threaded groove. One end of the pressing member penetrates through the inner wall of the plug-in sleeve and is fixedly connected to a gasket. The two pressing members are arranged in a mirror image.

[0016] Preferably, the other end of the pressing member is arc-shaped. The shape of the end of the abutting bolt close to the pressing member is round-headed and abuts against the other end of the pressing member.

[0017] Working principle: When the walking wheel rotates, the drive shaft of the device inserted into the inner part of the socket sleeve will drive the socket sleeve to rotate. The rotating socket sleeve drives the transmission head sleeved at the front end to rotate, so as to drive the planetary gear to start rotating and working, sharing the strong torque brought by the high driving force, and transmitting the force to the stable planetary gear. At this time, the swivel base starts to rotate, and the rotating swivel base drives the tooth column connected at the front end to rotate, so that the tooth column meshes with the surrounding gear connected by transmission and displaces around the tooth ring, further sharing the torque force, and driving the wheel body joint at the front end to rotate, so that the wheel body joint drives the wheel structure including the inner hub and the tire body to rotate, so as to drive the structure connected to the walking wheel to displace.

[0018] When installing the wheel structure of the walking wheel, first sleeve the tire body on the outer periphery of the inner hub, and then embed the fitting cover together with the connected abutting head on the outer surface of the inner hub, so that the abutting inclined surface of the abutting head abuts against the abutting inclined groove of the limiting part. As the abutting head goes deeper, the abutting inclined surface pushes the limiting part along the abutting inclined groove, so that the limiting part slides and displaces on the inner hub and exposes on the outer periphery of the inner hub, and is clamped into the special-shaped annular groove on the inner periphery of the tire body to limit the tire body. Subsequently, the wheel structure including the inner hub and the tire body is aligned with the wheel body joint for installation, and the bolt passes through the fitting cover and the connecting piece and is tightened and fixed on the external housing, so that the wheel structure including the inner hub and the tire body is stable, thus completing the installation.

[0019] When docking the walking wheel with the drive shaft of the device to which the walking wheel is to be installed, align the socket of the socket sleeve with the drive shaft for plugging and fixing. Then, use a screwdriver to screw the abutting bolt so that the abutting bolt goes deep into the thread groove, and make the round head structure of the abutting bolt abut against the arc-shaped structure of the pressing part, thereby applying force to the pressing part, so that the pressing part displaces along the trend of the arc-shaped structure, and the pressing part carries the gasket and abuts against the inserted drive shaft, increasing the friction between the drive shaft and the socket sleeve, resulting in the completion of the installation and fixing of the drive.

[0020] The present invention provides a walking wheel with a high bearing capacity structure. It has the following beneficial effects:

[0021] 1. The present invention effectively reduces the influence of heavy pressure and driving torque on the walking wheel, improves the bearing capacity of the walking wheel, enhances the stability of the walking wheel under high-load working conditions, reduces the deformation and damage problems caused by heavy pressure and large torque, and ensures the smoothness and safety of the equipment operation.

[0022] 2. The double planetary gear design of the present invention can effectively share and transmit the strong torque brought by the high driving force, further improving the bearing capacity of the walking wheel. When the walking wheel bears a large weight pressure, it can avoid the deformation and fracture of the drive shaft structure, ensure the stable transmission of force to the wheel structure, and improve the applicability and reliability of the walking wheel in heavy machinery and equipment.

[0023] 3. By limiting the carcass, the present invention effectively prevents the carcass from shifting and falling off the inner hub after being subjected to large torque and heavy pressure, ensures the stability of the carcass under high-load conditions, avoids equipment operation failures and safety accidents caused by the shifting and falling off of the carcass, and improves the reliability and service life of the walking wheel.

Detailed implementation manner

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment:

[0040] The embodiment of the present invention provides a walking wheel with a high load-bearing structure, including:

[0041] Please refer to the attached Figure 1 attachment Figure 2 and attachment Figure 4 , a protective housing 1. An anti-torsion high-load bearing shaft for reducing the influence of heavy pressure and driving torque is installed on the inner wall of the protective housing 1 to improve the load-bearing capacity of the walking wheel, so that the working stability of the walking wheel is improved. The front end of the anti-torsion high-load bearing shaft is connected to a wheel body joint 2 through a bolt;

[0042] Among them, please refer to the attached Figure 4 attachment Figure 11 and attachment Figure 12 , the anti-torsion high-load bearing shaft includes a planetary gear 14 installed at the rear end of the inner wall of the protective housing 1. The rear input end of the planetary gear 14 is fixedly connected to a transmission head 21. The front output end of the planetary gear 14 is provided with a stable planetary gear. The rear side of the external housing 5 is connected to the stable planetary gear. Among them, the stable planetary gear includes a rotating base 16 fixedly connected to the front driving end of the planetary gear 14. The front outer periphery of the rotating base 16 is rotatably connected to a stabilizing frame 17. A plurality of limiting grooves are provided on the front outer periphery of the stabilizing frame 17. A surrounding gear 20 is rotatably connected inside the limiting groove. The front middle end of the rotating base 16 is fixedly connected to a tooth column 19. The front end of the tooth column 19 penetrates through the middle end of the stabilizing frame 17 and meshes with a plurality of surrounding gears 20. The outer walls of the plurality of surrounding gears 20 are meshed and connected to a tooth ring 18. The outer wall of the tooth ring 18 is fixedly connected to the inner wall of the protective housing 1. The rear side of the wheel body joint 2 is connected to the front side of the stabilizing frame 17 through a bolt. Please refer to the attached Figure 4 attachment Figure 13, the outer peripheries of the wheel body joint 2 and the stabilizer 17 are both connected to the inner wall of the protective housing 1 through bearings 15 to reduce the friction suffered by the stabilizer 17 and the wheel body joint 2 during rotation inside the protective housing 1 and reduce the loss of the transmitted force;

[0043] Specifically, the double planetary gear design of the walking wheel enables the walking wheel to distribute part of the force to the multi-gear surrounding structure of the planetary gear when withstanding the torque force brought by the high driving force transmission of the installed equipment and the large weight pressure borne, so that the force can be dispersed, reducing the pressure on the main shaft transmitting the force, enabling the walking wheel to stably transmit the force to the wheel structure. Moreover, when the walking wheel bears a large weight pressure, the multi-gear matching outer ring structure of the double planetary gear can increase and thicken the transmission shaft structure on the structure, preventing the transmission shaft structure from deforming and breaking under the large weight pressure, thereby improving the bearing capacity of the walking wheel. Among them, as a further measure to improve the bearing capacity, the stable planetary gear is made more stable by adding a stabilizer 17 that restricts the surrounding gear 20, so that the surrounding gear 20 remains in a fixed position during rotation and transmission, and avoids shifting and improves the transmission stability when affected by the torque force. When the walking wheel rotates and works, the drive shaft of the equipment inserted into the socket 10 will drive the socket 10 to rotate. The rotating socket 10 drives the transmission head 21 sleeved at the front end to rotate, so as to drive the planetary gear 14 to start rotating and working, sharing the powerful torque brought by the high driving force, and transmitting the force to the stable planetary gear. At this time, the swivel base 16 starts to rotate, and the rotating swivel base 16 drives the tooth column 19 connected to the front end to start rotating, thereby causing the tooth column 19 to mesh and drive the surrounding gear 20 connected to it to displace around the tooth ring 18, further sharing the torque force, and driving the wheel body joint 2 at the front end to rotate, so that the wheel body joint 2 drives the wheel structure including the inner hub 3 and the carcass 4 to rotate, so as to drive the structure connected to the walking wheel to displace.

[0044] Please refer to the attached Figure 1 、the attached Figure 5 and the attached Figure 6 , for the inner hub 3, a carcass 4 is sleeved on the outer wall of the inner hub 3. A connecting piece 9 is fixedly connected to the inner periphery of the inner hub 3. A fitting cover 6 is arranged on the front side of the connecting piece 9. Both the fitting cover 6 and the connecting piece 9 are connected to the front side of the external housing 5 through bolts. Please refer to the attached Figure 6 -the attached Figure 8, a plurality of limiting members 8 slidably connected to the outer periphery of the inner hub 3, the inner periphery of the carcass 4 is sleeved on the outer periphery of the limiting members 8, an abutting inclined groove is formed in the inner periphery of the limiting members 8, a plurality of abutting heads 7 are fixedly connected to the outer periphery of the fitting cover 6, an abutting inclined surface is arranged at the rear end of the abutting head 7, the abutting inclined surface abuts against the abutting inclined groove, the outer peripheral section shape of the limiting member 8 is a special-shaped structure, a special-shaped ring groove is formed in the inner periphery of the carcass 4, and the outer peripheral section shape of the limiting member 8 fits the section shape of the special-shaped ring groove to prevent the carcass 4 from shifting and falling off the inner hub 3 under large torque and heavy pressure, and ensure the stability of the carcass 4;

[0045] Specifically, when installing the wheel structure of the walking wheel, first, the carcass 4 is sleeved on the outer periphery of the inner hub 3, and then the fitting cover 6 together with the connected abutting heads 7 is embedded into the outer surface of the inner hub 3, so that the abutting inclined surface of the abutting head 7 abuts against the abutting inclined groove of the limiting member 8. As the abutting head 7 goes deeper, the abutting inclined surface pushes the limiting member 8 along the abutting inclined groove, causing the limiting member 8 to slide and displace on the inner hub 3, and exposing the outer periphery of the inner hub 3, and snapping into the special-shaped ring groove on the inner periphery of the carcass 4 to limit the carcass 4. When the wheel structure is under a large weight pressure from above, the friction between the wheel structure and the ground increases. Under the influence of torque force, it can avoid the phenomenon that the carcass 4 fails to turn in time due to excessive friction during equipment turning, resulting in deviation and falling off. Subsequently, the wheel structure including the inner hub 3 and the carcass 4 is aligned with the wheel body joint 2 for installation, and the bolt passes through the fitting cover 6 and the connecting piece 9 and is tightened and fixed on the outer connecting shell 5 to make the wheel structure including the inner hub 3 and the carcass 4 stable, thus completing the installation.

[0046] Please refer to the appendix Figure 3 and appendix Figure 4 , the outer connecting shell 5, the outer connecting shell 5 is connected to the rear side of the protective shell 1 by bolts, so that the walking wheel is loaded on the corresponding equipment. A plug socket 10 is rotatably connected to the middle end of the outer connecting shell 5. A transmission head 21 is sleeved on the front end of the plug socket 10. The transmission head 21 is connected to the rear end of the anti-torsion high-load bearing shaft, so that the drive shaft of the equipment is inserted into the interior of the plug socket 10 to drive the walking wheel to move. Please refer to the appendix Figure 3 , appendix Figure 9 and appendix Figure 10, a pressure member 12 is slidably connected to the inner end of the threaded grooves opened at the left and right ends of the plug sleeve 10. The other end of the threaded groove is threadedly connected with an abutting bolt 11. One end of the pressure member 12 penetrates through the inner wall of the plug sleeve 10 and is fixedly connected with a gasket 13. The two pressure members 12 are arranged in a mirror image. The other end of the pressure member 12 is arc-shaped. The end of the abutting bolt 11 close to the pressure member 12 is round-headed and abuts against the other end of the pressure member 12, so as to apply pressure to the drive shaft after the drive shaft is inserted into the plug sleeve 10, further stabilizing the insertion stability of the drive shaft. During the process of the abutting bolt 11 penetrating into the threaded groove, the round-headed structure of the abutting bolt 11 will abut against the arc-shaped structure of the pressure member 12, thereby applying a force to the pressure member 12, causing the pressure member 12 to displace along the trend of the arc-shaped structure, so that the pressure member 12 carries the gasket 13 to abut against the inserted drive shaft, increasing the friction between the drive shaft and the plug sleeve 10.
