[0050] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0052] This application provides an auxiliary device for replacing the lower support roller shaft of a chain fence machine. For example... Figures 1 to 3 As shown, in some embodiments, the auxiliary device for replacing the lower support roller shaft of the chain fence machine includes a moving mechanism 10 and a lifting component 20. The lifting component 20 is disposed on the moving mechanism 10 and can rotate relative to the moving mechanism 10. The lifting component 20 abuts against the lower support roller shaft 30 and is used to support the lower support roller shaft 30. The lifting component 20 drives the lower support roller shaft 30 to rise and fall.

[0053] Specifically, such as Figures 1 to 3 As shown, the mobile mechanism 10 is mounted on the ground and can move relative to the ground. In this embodiment, the mobile mechanism 10 can be a wheeled or track-type mobile structure. In practical application scenarios, by setting a mobile mechanism 10 that can move relative to the ground, the device can meet the application needs of different areas.

[0054] like Figure 1 and Figure 3 As shown, the lifting assembly 20 is connected to the moving mechanism 10. Specifically, the lifting assembly 20 is rotatably connected to the moving mechanism 10, allowing the lifting assembly 20 to rotate relative to the moving mechanism 10. The lifting assembly 20 abuts against the lower side of the lower support roller shaft 30, supporting one end of the lower support roller shaft 30. In this embodiment, the lifting assembly 20 can rotate relative to the moving mechanism 10 within a certain angle range; further, the lifting assembly 20 can rotate 360 ​​degrees relative to the moving mechanism 10. The lifting assembly 20 can be made of hard materials such as steel or alloys, meeting the strength requirements for supporting the lower support roller shaft 30.

[0055] For example, such as Figure 3 As shown, in practical applications, due to the limited space of the replacement channel 100 for the lower support roller shaft 30, and the fact that the lower support roller shaft 30 is very heavy and long, it is difficult to control the removal direction of the lower support roller shaft 30 when handling it. Therefore, when the removal direction of the lower support roller shaft 30 deviates, by rotating the lifting component 20 relative to the moving mechanism 10, the appropriate position between the lifting component 20 and the lower support roller shaft 30 can be adjusted in time while the moving mechanism 10 is stationary, so that the lower support roller shaft 30 can be supported on the lifting component 20.

[0056] like Figure 3As shown, in the replacement channel 100 of the lower support roller shaft 30, during the process of hoisting one end of the lower support roller shaft 30 to the lifting assembly 20 using a hand-operated hoist 101, the lower support roller shaft 30 is prone to center offset, causing one side to tilt upwards. In this embodiment, by designing a lifting assembly 20 that can be raised and lowered, one end of the lower support roller shaft 30 can be hoisted onto the lifting assembly 20. This eliminates the need for operators to hold the lower support roller shaft 30 during the replacement process, saving manpower.

[0057] For example, such as Figure 3 As shown, in practical applications, when one side of the lower support roller shaft 30 tilts upwards, the lifting assembly 20 can be raised to support the tilted side of the lower support roller shaft 30. Then, the lifting assembly 20 supporting the tilted side of the lower support roller shaft 30 is lowered to a horizontal position, and the lower support roller shaft 30 is pulled out of the channel 100 using the hand chain hoist 101. This process eliminates the need for operators to manually support the lower support roller shaft 30, saving manpower, preventing injury during operation, and improving the replacement efficiency of the lower support roller shaft 30.

[0058] The chain fence machine lower support roller axle replacement auxiliary device provided in this application embodiment includes a movable mechanism 10 that can move relative to the ground and a lifting component 20 that can be raised and lowered. By setting the lifting component 20 on the movable mechanism 10 and designing the lifting component 20 to rotate relative to the movable mechanism 10, and by abutting the lower support roller axle 30 with the lifting component 20, the lower support roller axle 30 can be effectively supported. Moreover, the lower support roller axle 30 can be raised and lowered by the raising and lowering of the lifting component 20, which can effectively prevent the lower support roller axle 30 from rolling when it is removed from the chain fence machine. At the same time, the use of this device eliminates the need for operators to support the lower support roller axle 30 during the replacement process, which can save manpower and improve the replacement efficiency of the lower support roller axle 30.

[0059] like Figure 1 As shown, the auxiliary device for replacing the lower support roller shaft of the chain fence machine includes a control panel 70. The control panel 70 is located on the lifting assembly 20 and is used to control the lifting of the lifting assembly 20. The control panel 70 is electrically connected to the lifting assembly 20. The control panel 70 can be a touch screen or a physical button panel; for example, when the control panel 70 is a physical button panel, it includes a raise button, a lower button, and an emergency stop button, which can effectively control the lifting of the lifting assembly 20 and its emergency stop.

[0060] like Figure 1 and Figure 2As shown, the moving mechanism 10 includes a base 11 and multiple sets of casters 12. The lifting assembly 20 is disposed on the base 11, and the multiple sets of casters 12 are respectively disposed on the base 11. For example, three sets of casters can be respectively provided on the lower part of the base 11, which can play a role in stable operation and support.

[0061] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the lifting assembly 20 includes a rotating mechanism 21, which is disposed on the moving mechanism 10 and is rotatable relative to the moving mechanism 10. Specifically, the rotating mechanism 21 is rotatably connected to the moving mechanism 10, thereby allowing the rotating mechanism 21 to rotate relative to the moving mechanism 10. The rotating mechanism 21 can rotate relative to the moving mechanism 10 within a certain angle range; furthermore, the rotating mechanism 21 can rotate 360 ​​degrees relative to the moving mechanism 10, thereby adjusting the positional relationship between the lifting assembly 20 and the lower support roller shaft 30 from different directions, and quickly supporting the lower support roller shaft 30 on the lifting assembly 20.

[0062] like Figure 2 As shown, the rotating mechanism 21 includes a base 211, a connecting part 212, and a rotating shaft 213. One end of the rotating shaft 213 is connected to the moving mechanism 10, and the connecting part 212 is connected to the other end of the rotating shaft 213. The base 211 is mounted on the connecting part 212 and provides support. It can be understood that the rotating shaft 213 can be rotatably connected to both the connecting part 212 and the moving mechanism 10 simultaneously; or, the rotating shaft 213 can be rotatably connected to one of the connecting part 212 and the moving mechanism 10, and fixedly connected to the other. For example, when the rotating shaft 213 is rotatably connected to the moving mechanism 10, it can be fixedly connected to the connecting part 212. In this case, the base 211, rotating shaft 213, and connecting part 212 can rotate around the rotating shaft 213. In practical applications, the base 211, rotating shaft 213, and connecting part 212 can be manually pushed to rotate around the rotating shaft 213.

[0063] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the lifting assembly 20 includes a lifting rod 22 and a hydraulic cylinder 23. The first end of the lifting rod 22 is connected to the rotating mechanism 21, and the second end of the lifting rod 22 abuts against the lower support roller shaft 30. The hydraulic cylinder 23 is used to drive the lifting rod 22 to rise and fall. Specifically, as... Figure 1 , Figure 2As shown, the first end of the lifting rod 22 is connected to the base 211. The first end of the lifting rod 22 can be detachably connected to the base 211 by bolts, facilitating disassembly and installation. The hydraulic cylinder 23, mounted on the base 211, drives the lifting rod 22 to perform lifting movements. The lifting rod 22 and the hydraulic cylinder 23 can rotate synchronously with the base 211.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, the lifting rod 22 includes a first support member 221 disposed at the second end of the lifting rod 22 for supporting the lower support roller shaft 30. The shape and size of the first support member 221 are adapted to the outer shape of the lower support roller shaft 30. The first support member 221 is provided with a U-shaped groove, and the lower support roller shaft 30 is supported in the U-shaped groove during use.

[0065] like Figure 1 As shown, in some embodiments, the lifting assembly 20 includes a mobile power source 24 disposed on the rotating mechanism 21 for supplying power to the hydraulic cylinder 23. The mobile power source 24 can be mounted on the base 211 and can rotate synchronously with the base 211. The mobile power source 24 can be a rechargeable mobile power source, which can provide power to the hydraulic system when used in the field.

[0066] like Figure 1 As shown, in some embodiments, the auxiliary device for replacing the lower support roller axle of the chain fence machine further includes a translation mechanism 40. The translation mechanism includes a support frame 41 and a second supporting member 42. The lower part of the support frame 41 is connected to the moving mechanism 10, and the second supporting member 42 is connected to the upper part of the support frame 41. The lower support roller axle 30 is supported by the second supporting member 42, and the lower support roller axle 30 can translate relative to the second supporting member 42. The shape and size of the second supporting member 42 are adapted to the external shape of the lower support roller axle 30. Specifically, as shown... Figure 2 As shown, the lower end of the support frame 41 can be detachably connected to the base 211 by bolts, and the second support member 42 can be detachably connected to the other end of the support frame 41 by bolts to support the lower support roller shaft 30.

[0067] like Figure 3As shown, in practical applications, due to the large weight and long length of the lower support roller shaft 30, when replacing the lower support roller shaft 30 in the channel 100, a set of devices can be used to simultaneously raise the lower support roller shaft 30 to a suitable position above the second support member 42 (for example, a set of devices can simultaneously support both ends of the lower support roller shaft 30, and a set of devices can simultaneously raise both ends of the lower support roller shaft 30 to a suitable position above the second support member 42), and then lower the lower support roller shaft 30 so that the lower side of the lower support roller shaft 30 can abut against the second support member 42. Since the lower support roller shaft 30 can slide relative to the second support member 42, it can be moved forward or backward by manual pushing, and the lower support roller shaft 30 can be smoothly pulled out of the channel 100.

[0068] like Figure 1 As shown, to facilitate smoother translation and sliding of the lower support roller shaft 30 in the slide groove 421, the second support member 42 is provided with a slide groove 421, on which the lower support roller shaft 30 is supported and can slide translationally. The slide groove 421 is U-shaped, and the lower support roller shaft 30 can be supported in the U-shaped slide groove 421. Specifically, a first roller 4211, a second roller 4212, and a third roller 4213 are provided in the slide groove 421. The first roller 4211 and the second roller 4212 are respectively disposed on the two sides of the groove wall, and the third roller 4213 is disposed on the bottom of the groove.

[0069] like Figure 1 , Figure 2 As shown, in some embodiments, the auxiliary device for replacing the lower support roller shaft of the chain fence machine includes a limiting pin 50. The first end of the limiting pin 50 abuts against the surface of the lifting assembly 20, and the second end of the limiting pin 50 passes through the lifting assembly 20 and the moving mechanism 10. The limiting pin 50 is used to restrict the rotation of the lifting assembly 20 relative to the moving mechanism 10. Specifically, the first end of the limiting pin 50 can hook onto the upper surface of the base 211, and the second end of the limiting pin 50 can pass through the base 211 and the base 11. In practical applications, because the lower support roller shaft 30 is bulky and long, relative rotation between the base 211 and the base 11 is likely to occur, posing a significant safety risk. By inserting the positioning pin 50 into the base 211 and the base 11, relative rotation between the base 211 and the base 11 can be avoided.

[0070] like Figure 1 , Figure 2 and Figure 3 As shown, in order to better control the direction of movement, the chain fence machine's lower support roller axle replacement auxiliary device includes a handrail 60 installed on the lifting assembly 20. Specifically, the handrail 60 is mounted on the base 211 and can rotate synchronously with the base 211. A control panel 70 is installed on the handrail 60, facilitating the control of the lifting and lowering of the upper lifting rod 22 and its emergency stop.

[0071] The chain fence machine lower support roller axle replacement auxiliary device provided in the foregoing embodiments of this application eliminates the need for operators to hold the lower support roller axle 30 during the replacement process. This not only saves manpower but also reduces the personal safety risks to personnel during operation and effectively improves the replacement efficiency of the lower support roller axle 30.

[0072] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. All embodiments obtained by any modifications, alterations or equivalent substitutions made by those skilled in the art without departing from the technical concept of this application shall fall within the scope of protection of the claims of this application.
