Description

Technical Field

[0001] This application belongs to the field of sand mill technology, and particularly relates to an auxiliary sand mill cylinder disassembly device. Background Technology Background Technology

[0003] In the daily maintenance and repair of sand mills, the replacement and repair of internal parts are crucial to ensuring the normal operation of the equipment. The mill cylinder, as one of its core components, is not only complex to disassemble and assemble, but also often requires the use of large lifting equipment such as overhead cranes. This increases the difficulty of operation and raises safety risks. Especially in production environments with limited space or compact equipment layouts, using overhead cranes to disassemble and assemble the cylinder is particularly inconvenient, inefficient, and may affect the normal operation of other equipment.

[0004] In view of this, there is an urgent need for a solution that can simplify the disassembly and assembly process of sand mill cylinders, improve operational efficiency, and reduce safety risks. However, most existing tools and methods on the market have not been effectively optimized for this specific need of sand mills, resulting in many inconveniences in actual operation. Therefore, inventing a device that can utilize the existing conditions of sand mill equipment to achieve quick and easy disassembly and assembly of the cylinder has become an urgent technical problem to be solved. Utility Model Content

[0005] The purpose of this application is to provide an auxiliary device for disassembling the cylinder of a sand mill, which can solve the above-mentioned problems.

[0006] The purpose of this application is to provide an auxiliary device for disassembling a sand mill cylinder, including an equipment mounting frame and a bearing seat bracket, comprising:

[0007] There are two mounting components, and both mounting components are connected to the device mounting bracket.

[0008] The guide rail assembly is positioned above the mounting assembly and connected to it.

[0009] A pulley assembly is mounted on the guide rail assembly and is able to slide on the guide rail assembly;

[0010] A saddle assembly is mounted on the pulley assembly and is used to support the grinding machine cylinder;

[0011] A support component, located at the end of the guide rail assembly furthest from the equipment mounting bracket, is used to support the guide rail assembly;

[0012] The grinding machine cylinder is supported by a saddle assembly, and the grinding machine cylinder is moved outward by a pulley assembly, thereby enabling the maintenance and replacement of internal parts.

[0013] The equipment mounting bracket is used to fix and support other components. Two mounting components are provided, each connected to the bracket. The mounting components secure the guide rail assembly, ensuring its stability and accuracy during assembly and disassembly. The guide rail assembly is positioned above and tightly connected to the mounting components. The guide rail assembly provides a sliding track for the pulley assembly, allowing for smooth and controllable movement. The pulley assembly is mounted on the guide rail assembly and can slide freely along the rail, ensuring easy movement of the grinding machine cylinder. A saddle assembly is mounted on the pulley assembly to support the outer ring of the grinding machine cylinder. A support assembly is located at the end of the guide rail assembly furthest from the mounting bracket, supporting the guide rail assembly and the weight throughout the assembly and disassembly process.

[0014] During disassembly and assembly, the outer ring of the grinding mill cylinder is first supported by the saddle assembly. Then, by pushing the pulley assembly to slide on the guide rail assembly, the grinding mill cylinder is moved smoothly outward. During this process, internal parts can be inspected and replaced without the need for overhead cranes or other lifting equipment. Through innovative component design and assembly methods, the grinding mill cylinder can be quickly and easily disassembled and assembled, simplifying the disassembly and assembly steps, shortening maintenance time, and improving the reliability and service life of the equipment. At the same time, the elimination of reliance on external lifting equipment reduces disassembly and assembly costs and safety risks.

[0015] Furthermore, the installation components include:

[0016] Steel plate;

[0017] Round tube;

[0018] The steel plate and the round pipe are welded together, and one side of the steel plate is welded to the equipment mounting frame.

[0019] The steel plate, as the main structural component of the mounting assembly, provides sufficient strength and stability. Round tubes are welded to the steel plate, forming a support structure that connects to the equipment mounting frame. This not only enhances the stability of the entire mounting assembly but also facilitates connection to the guide rail assembly. One side of the steel plate is welded to the equipment mounting frame, ensuring the robustness and stability of the mounting assembly. This welding method is not only simple and reliable but also capable of withstanding various forces and weights generated during assembly and disassembly.

[0020] Furthermore: the guide rail assembly includes:

[0021] There are two guide rails, spaced apart.

[0022] The support component includes a first support round steel and a second support round steel disposed on the guide rail. The first support round steel is used to connect with the mounting assembly, and the second support round steel is used to connect with the support assembly.

[0023] Baffles are installed at both ends of the guide rail;

[0024] The first circular retaining ring is mounted on the support member;

[0025] Stiffening ribs are installed between the support and the guide rail;

[0026] The baffle, guide rail, first circular retaining ring, supporting round steel and stiffening plate are welded together, and the second supporting round steel is provided with through holes and connected to the supporting assembly by bolts and nuts.

[0027] The guide rail system features two rails spaced apart, providing a stable sliding track for the pulley assembly and ensuring smooth movement of the sand mill cylinder during assembly and disassembly. The first supporting round steel bar serves as the connection between the guide rail assembly and the mounting assembly, ensuring the guide rail assembly is securely installed, thus guaranteeing the stability and reliability of the entire assembly and disassembly device. The second supporting round steel bar connects to the support assembly using bolts and nuts. This facilitates adjustment and positioning during assembly and disassembly, and enhances the connection strength between the guide rail assembly and the support assembly, ensuring the overall stability of the assembly and disassembly device. Baffles are located at both ends of the guide rail, preventing the pulley assembly from detaching from the guide rail during sliding, ensuring safe and stable sliding of the pulley assembly on the guide rail, and avoiding potential accidents during assembly and disassembly. A first circular retaining ring is located on the support component, serving a limiting function. The stiffening ribs are placed between the support and the guide rail, which enhances the overall structural strength of the guide rail assembly, improves the service life and reliability of the disassembly and assembly device, optimizes the stress distribution of the guide rail assembly, and reduces deformation and damage caused by uneven stress.

[0028] Meanwhile, the through holes on the second support round steel and the connection method with the support assembly via bolts and nuts make the connection between the guide rail assembly and the support assembly more flexible and reliable. This not only facilitates adjustment and positioning during disassembly and assembly but also improves the overall stability and adaptability of the disassembly and assembly device, and ensures the firmness and safety of the connection.

[0029] Furthermore, the pulley assembly includes:

[0030] The support plate has a first weight-reducing hole on its surface;

[0031] Welded components are located at the bottom of the support plate and are used to support and fix the support plate.

[0032] U-shaped single pulley, installed on the welded part;

[0033] Second circular retaining ring

[0034] The U-shaped single pulley is provided with four pulleys, and each U-shaped single pulley is fixed to the welded part by a pin and the second circle.

[0035] As the main load-bearing structure of the pulley assembly, the support plate features a first weight-reducing hole on its surface. This not only reduces the overall weight of the pulley assembly and lowers energy consumption during assembly and disassembly, but also improves its structural strength and stability. Welded components are located at the bottom of the support plate to support and secure it. Four U-shaped single-wheel pulleys are installed on the welded components, enhancing the load-bearing capacity of the pulley assembly and ensuring smooth sliding on the guide rail. Each U-shaped single-wheel pulley is fixed to the welded component by a pin and a second circular retaining ring. This connection method is simple, reliable, and facilitates disassembly and maintenance. Furthermore, the design of the U-shaped single-wheel pulleys considers compatibility with the guide rail, reducing friction and wear during sliding and extending the service life of the pulley assembly.

[0036] The second circular retaining ring, in conjunction with the pin, secures the U-shaped single-wheel pulley to its position on the welded component. This prevents the pulley from detaching or shifting during sliding, ensuring the stability and safety of the pulley assembly. Optimized structural design and connection methods improve the pulley assembly's load-bearing capacity, smoothness of sliding, and service life. This not only simplifies the assembly and disassembly process and improves maintenance efficiency but also reduces assembly and disassembly costs and safety risks, providing strong support for the quick and easy assembly and disassembly of the sand mill cylinder.

[0037] Furthermore, the welded component includes:

[0038] The main rod consists of two rods spaced apart. The cross-section of the rod is circular, and the inner diameter of the rod is matched with that of the U-shaped single pulley on both sides. The rods are also provided with through holes for the pin fitting.

[0039] The secondary rod is used to connect to the main rod;

[0040] Threaded posts are installed on the main rod, and there are four of them. The height of the support plate is adjusted by two nuts for each threaded post.

[0041] The width between the two threaded posts is greater than the width of the saddle assembly.

[0042] The main rod has a circular cross-section, matching the U-shaped single-wheel pulley, ensuring the pulley can be stably installed on the welded component. Pin-fitting through holes on both sides of the main rod allow the U-shaped single-wheel pulley to be securely fixed to the welded component via pins and the second circular retaining ring, preventing the pulley from falling off or shifting during sliding and improving the stability and safety of the pulley assembly. The auxiliary rod connects the two main rods, forming the overall frame of the welded component. This not only enhances the structural strength of the welded component but also optimizes its stress distribution, enabling the pulley assembly to withstand greater forces and weights.

[0043] The threaded posts are mounted on the main rod, and the height of the support plate can be adjusted using two nuts. This not only facilitates adjustment and positioning during assembly and disassembly but also ensures a good fit between the pulley assembly and the guide rail assembly, reducing friction and wear caused by height mismatch. Furthermore, the width between the two threaded posts is greater than the width of the saddle assembly, providing sufficient installation space for the saddle assembly and ensuring its stability and safety during sliding.

[0044] Furthermore, the saddle assembly includes;

[0045] The base plate is mounted on the support plate;

[0046] Support plates are spaced apart on the base, and their tops are provided with arc-shaped grooves that match the outer diameter of the cylinder.

[0047] A reinforcing plate is installed on the base plate and connected to the two supporting upright plates;

[0048] The base plate has two second weight-reduction holes on its surface, which are symmetrically arranged on the base plate about the reinforcing plate.

[0049] The base plate, serving as the fundamental structure of the saddle assembly, is mounted on the support plate, providing robust support for the entire saddle assembly. Two secondary weight-reducing holes on its surface reduce the overall weight of the saddle assembly, lowering energy consumption. Supporting uprights are spaced apart on the base plate, and their top arc-shaped grooves perfectly match the outer diameter of the sand mill cylinder, ensuring the cylinder can be placed stably and securely on the saddle assembly, preventing wobbling or slippage during assembly and disassembly. Reinforcing plates are mounted on the base plate and firmly connected to the two supporting uprights, enhancing the structural strength of the saddle assembly and ensuring the stability and reliability of the supporting uprights.

[0050] Meanwhile, the two secondary weight-reduction holes on the base plate, symmetrically positioned about the reinforcing plate, not only further reduce the weight of the saddle assembly and improve its flexibility and portability, but also reduce energy consumption and costs during assembly and disassembly. The design of the secondary weight-reduction holes and the arc-shaped groove allows the saddle assembly to easily support the cylinder, providing strong support for the quick and easy assembly and disassembly of the sand mill cylinder. This not only simplifies the assembly and disassembly process and improves maintenance efficiency, but also reduces assembly and disassembly costs and safety risks, bringing great convenience to the maintenance and use of the sand mill.

[0051] Furthermore, the support component includes;

[0052] There are two risers, one end of which has a through hole and is connected to the guide rail assembly by bolts and nuts.

[0053] A horizontal pipe is installed between two vertical pipes and is used to connect the two vertical pipes;

[0054] The other end of the riser is equipped with an adjustment disc with a threaded through hole in the center. The height of the support assembly is adjusted by bolts, thereby adjusting the guide rail assembly to a horizontal position.

[0055] Two risers serve as the vertical support structure for the support assembly, located on either side of the guide rail assembly. Each riser has a through hole at one end, connecting to the guide rail assembly's support components via bolts and nuts, ensuring the stability and reliability of the guide rail assembly. A horizontal pipe is positioned between the two risers to connect them, further enhancing the stability of the support assembly. This not only makes the support assembly more robust and durable but also optimizes its stress distribution, reducing deformation and damage caused by uneven stress.

[0056] The other end of the riser is equipped with an adjusting disc with a threaded through hole in its center. By engaging a bolt with the threaded through hole, the height of the support assembly can be easily adjusted, thereby achieving precise adjustment of the horizontal position of the guide rail assembly. This not only improves the flexibility and accuracy during assembly and disassembly but also ensures the stability and reliability of the guide rail assembly in its horizontal position.

[0057] The beneficial effects of this application are:

[0058] 1. During the disassembly and assembly process, the outer ring of the grinding machine cylinder is first supported by the saddle assembly. Then, by pushing the pulley assembly to slide on the guide rail assembly, the grinding machine cylinder is moved outward smoothly. During this process, the internal parts of the equipment can be inspected and replaced without the need for hoisting equipment such as overhead cranes.

[0059] 2. Through innovative component design and assembly methods, the sand mill cylinder can be quickly and easily disassembled and assembled, simplifying the disassembly and assembly steps, shortening maintenance time, and improving the reliability and service life of the equipment. At the same time, it eliminates the need for external hoisting equipment, reducing disassembly and assembly costs and safety risks.

[0060] 3. Threaded posts are mounted on the main rod, and the height of the support plate can be adjusted using two nuts. This not only facilitates adjustment and positioning during assembly and disassembly but also ensures a good fit between the pulley assembly and the guide rail assembly, reducing friction and wear caused by height mismatch. Furthermore, the width between the two threaded posts is greater than the width of the saddle assembly, providing sufficient installation space for the saddle assembly and ensuring its stability and safety during sliding.

[0070] Example 1:

[0071] like Figures 1 to 5As shown, this application embodiment provides an auxiliary sand mill cylinder disassembly device, including an equipment mounting frame 100 and a bearing seat bracket 110, comprising:

[0072] There are two mounting components 200, and both mounting components 200 are connected to the device mounting bracket 100.

[0073] The guide rail assembly 300 is disposed above the mounting assembly 200 and connected to the mounting assembly 200;

[0074] The pulley assembly 400 is mounted on the guide rail assembly 300 and is capable of sliding on the guide rail assembly 300;

[0075] The saddle assembly 500 is mounted on the pulley assembly 400 and is used to support the grinding machine cylinder;

[0076] A support component 600 is disposed at the end of the guide rail assembly 300 away from the equipment mounting bracket 100, and is used to support the guide rail assembly 300.

[0077] The saddle assembly 500 supports the outer ring of the grinding machine cylinder, and the pulley assembly 400 pushes the grinding machine cylinder outward, thereby enabling the maintenance and replacement of internal parts.

[0078] In some embodiments of this application, such as Figure 1 As shown, the equipment mounting bracket 100 is used to fix and support other components. Two mounting components 200 are provided, each connected to the equipment mounting bracket 100. The mounting components 200 are used to fix the guide rail assembly 300, ensuring its stability and accuracy during assembly and disassembly. The guide rail assembly 300 is positioned above the mounting component 200 and is tightly connected to it. The guide rail assembly 300 provides a sliding track for the pulley assembly 400, enabling smooth and controllable movement. The pulley assembly 400 is positioned on the guide rail assembly 300 and can slide freely on the guide rail 310, ensuring easy movement of the grinding machine cylinder.

[0079] During disassembly and assembly, the outer ring of the grinding mill cylinder is first supported by the saddle assembly 500. Then, by pushing the pulley assembly 400 to slide on the guide rail assembly 300, the grinding mill cylinder is moved smoothly outward.

[0085] Among them, the steel plate 210 and the round pipe 220 are welded to each other, and one side of the steel plate 210 is welded to the equipment mounting frame 100.

[0086] In this embodiment, the steel plate 210, as the main structural component of the mounting assembly 200, provides sufficient strength and stability. The circular tube 220 is welded to the steel plate 210, forming a support structure connected to the equipment mounting frame 100. This not only enhances the stability of the entire mounting assembly 200 but also facilitates connection with the guide rail assembly 300. One side of the steel plate 210 is welded to the equipment mounting frame 100, ensuring the robustness and stability of the mounting assembly 200. This welding method is not only simple and reliable but also capable of withstanding various forces and weights generated during assembly and disassembly.

[0087] Example 3:

[0088] This application provides an auxiliary sand mill cylinder disassembly device. In addition to the above-mentioned technical features, the auxiliary sand mill cylinder disassembly device of this application also includes the following technical features.

[0089] like Figure 1 and Figure 2 As shown, the guide rail assembly 300 includes:

[0090] There are two guide rails 310, which are spaced apart.

[0091] The support member 320 includes a first support round steel 321 and a second support round steel 322 disposed on the guide rail 310. The first support round steel 321 is used to connect with the mounting assembly 200, and the second support round steel 322 is used to connect with the support assembly 600.

[0092] Baffles 330 are disposed at both ends of guide rail 310;

[0093] The first circular retaining ring 340 is disposed on the support member 320;

[0094] Rib plate 350 is disposed between support member 320 and guide rail 310;

[0095] The baffle 330, guide rail 310, first circular retaining ring 340, supporting round steel and stiffening plate 350 are welded together, and the second supporting round steel 322 is provided with through holes and is connected to the supporting assembly 600 by bolts and nuts.

[0096] In this embodiment, the guide rail 310 has two rails 310 spaced apart, providing a stable sliding track for the pulley assembly 400 and ensuring smooth movement of the mill cylinder during assembly and disassembly. The first support round steel 321 serves as the connection between the guide rail assembly 300 and the mounting assembly 200, ensuring the guide rail assembly 300 is securely mounted on the mounting assembly 200, thus guaranteeing the stability and reliability of the entire assembly and disassembly device. The second support round steel 322 is used to connect to the support assembly 600, secured by bolts and nuts. This not only facilitates adjustment and positioning during assembly and disassembly but also enhances the connection strength between the guide rail assembly 300 and the support assembly 600, ensuring the overall stability of the assembly and disassembly device. Baffles 330 are disposed at both ends of the guide rail 310. The baffles 330 prevent the pulley assembly 400 from detaching from the guide rail 310 during sliding, ensuring that the pulley assembly 400 can slide safely and stably on the guide rail 310, thereby avoiding potential accidents during disassembly and assembly. A first circular retaining ring 340 is disposed on the support member 320, serving a limiting function. Rib plates 350 are disposed between the support member 320 and the guide rail 310, enhancing the overall structural strength of the guide rail assembly 300, improving the service life and reliability of the disassembly and assembly device, and optimizing the stress distribution of the guide rail assembly 300, reducing deformation and damage caused by uneven stress.

[0097] Meanwhile, the through holes provided on the second support round steel 322 and the connection method between the guide rail assembly 300 and the support assembly 600 via bolts and nuts make the connection between the guide rail assembly 300 and the support assembly 600 more flexible and reliable. This not only facilitates adjustment and positioning during disassembly and assembly but also improves the overall stability and adaptability of the disassembly and assembly device, and ensures the firmness and safety of the connection.

[0098] Example 4:

[0099] This application provides an auxiliary sand mill cylinder disassembly device. In addition to the above-mentioned technical features, the auxiliary sand mill cylinder disassembly device of this application also includes the following technical features.

[0100] like Figures 1 to 4 As shown, the pulley assembly 400 includes:

[0101] The support plate 410 has a first weight-reducing hole 411 on its surface;

[0102] Welding component 420 is disposed at the bottom of support plate 410 and is used to support and fix support plate 410;

[0103] U-shaped single pulley 430 is mounted on welded part 420;

[0104] The second circular retaining ring is 440.

[0105] Among them, four U-shaped single pulleys 430 are provided, and each U-shaped single pulley 430 is fixed to the welded part 420 by a pin.

[0106] In this embodiment, the support plate 410 serves as the main load-bearing structure of the pulley assembly 400. The first weight-reducing hole 411 on its surface not only reduces the weight of the entire pulley assembly 400 and lowers energy consumption during assembly and disassembly, but also improves its structural strength and stability. A welded component 420 is disposed at the bottom of the support plate 410 to support and fix the support plate 410. Four U-shaped single-wheel pulleys 430 are provided and respectively installed on the welded component 420. This not only improves the load-bearing capacity of the pulley assembly 400 but also ensures its smooth sliding on the guide rail 310. Each U-shaped single-wheel pulley 430 is fixed to the welded component 420 by a pin and a second circular retaining ring 440. This connection method is simple and reliable, facilitating assembly, disassembly, and maintenance. Furthermore, the design of the U-shaped single-wheel pulley 430 also considers compatibility with the guide rail 310, reducing friction and wear during sliding and extending the service life of the pulley assembly 400.

[0107] The second circular retaining ring 440, in conjunction with the pin, secures the U-shaped single-wheel pulley 430 to the welded part 420. This prevents the pulley from falling off or shifting during sliding, ensuring the stability and safety of the pulley assembly 400. By optimizing the structural design and connection method, the load-bearing capacity, smoothness of sliding, and service life of the pulley assembly 400 are improved. This not only simplifies the disassembly and assembly process and improves maintenance efficiency but also reduces disassembly and assembly costs and safety risks, providing strong support for the quick and easy disassembly and assembly of the sand mill cylinder.

[0108] Furthermore, weldment 420 includes:

[0109] The main rod 421 has two rods spaced apart. Its cross-section is circular. Its two sides match the inner diameter of the U-shaped single pulley 430 and are provided with through holes for the pin fitting.

[0110] Sub-rod 422 is used to connect to main rod 421;

[0111] Threaded posts 423 are installed on the main rod 421 and there are four of them. Each threaded post 423 adjusts the height of the support plate 410 through two nuts.

[0112] The width between the two threaded posts 423 is greater than the width of the saddle assembly 500.

[0113] In some embodiments of this application, the main rod 421 has a circular cross-section, matching the U-shaped single-wheel pulley 430, ensuring that the pulley can be stably installed on the welded component 420. The pin-fitting through holes on both sides of the main rod 421 allow the U-shaped single-wheel pulley 430 to be securely fixed to the welded component 420 via pins and the second circular retaining ring 440, preventing the pulley from falling off or shifting during sliding and improving the stability and safety of the pulley assembly 400. The secondary rod 422 connects the two main rods 421, forming the overall frame of the welded component 420. This not only enhances the structural strength of the welded component 420 but also optimizes its stress distribution, enabling the pulley assembly 400 to withstand greater forces and weights.

[0114] Threaded posts 423 are mounted on the main rod 421, and the height of the support plate 410 can be adjusted using two nuts. This not only facilitates adjustment and positioning during assembly and disassembly but also ensures a good fit between the pulley assembly 400 and the guide rail assembly 300, reducing friction and wear caused by height mismatch. Furthermore, the width between the two threaded posts 423 is greater than the width of the saddle assembly 500, providing sufficient installation space for the saddle assembly 500 and ensuring its stability and safety during sliding.

[0115] Example 5:

[0116] This application provides an auxiliary sand mill cylinder disassembly device. In addition to the above-mentioned technical features, the auxiliary sand mill cylinder disassembly device of this application also includes the following technical features.

[0117] like Figures 2 to 4 As shown, the saddle assembly 500 includes;

[0118] The base plate 510 is mounted on the support plate 410;

[0119] Support plates 520 are spaced apart on the base, and their tops are provided with arc-shaped grooves 521 that match the outer diameter of the cylinder.

[0120] A reinforcing plate 530 is mounted on the base plate 510 and connected to two supporting upright plates 520;

[0121] The base plate 510 has a second weight reduction hole 540 on its surface. There are two second weight reduction holes 540, which are symmetrically arranged on the base plate 510 about the reinforcing plate 530.

[0122] In this embodiment, the base plate 510 serves as the foundation structure of the saddle assembly 500, mounted on the support plate 410, providing solid support for the entire saddle assembly 500. Two second weight-reducing holes 540 on its surface reduce the overall weight of the saddle assembly 500, lowering energy consumption. Support plates 520 are spaced apart on the base plate 510, and their top arc-shaped grooves 521 perfectly match the outer diameter of the mill cylinder, ensuring the cylinder can be placed stably and securely on the saddle assembly 500, preventing shaking or slippage during assembly and disassembly. Reinforcing plates 530 are mounted on the base plate 510 and firmly connected to the two support plates 520, enhancing the structural strength of the saddle assembly 500 and ensuring the stability and reliability of the support plates 520.

[0123] Meanwhile, the two second weight-reducing holes 540 on the base plate 510, symmetrically arranged about the reinforcing plate 530, not only further reduce the weight of the saddle assembly 500 and improve its flexibility and portability, but also reduce energy consumption and costs during disassembly and assembly. The design of the second weight-reducing holes 540 and the arc-shaped groove 521 allows the saddle assembly 500 to easily support the cylinder, providing strong support for the quick and easy disassembly and assembly of the sand mill cylinder. This not only simplifies the disassembly and assembly process and improves maintenance efficiency, but also reduces disassembly and assembly costs and safety risks, bringing great convenience to the maintenance and use of the sand mill.

[0124] Example 6:

[0125] This application provides an auxiliary sand mill cylinder disassembly device. In addition to the above-mentioned technical features, the auxiliary sand mill cylinder disassembly device of this application also includes the following technical features.

[0126] like Figure 1 , Figure 2 and Figure 5 As shown, the support component 600 includes;

[0127] There are two risers 610. One end of the riser 610 has a through hole and is connected to the guide rail assembly 300 by bolts and nuts.

[0128] A horizontal pipe 620 is installed between two vertical pipes 610 and is used to connect the two vertical pipes 610.

[0129] The other end of the riser 610 is provided with an adjusting circular plate 630, which has a threaded through hole in the center. The height of the support assembly 600 is adjusted by bolts, thereby adjusting the guide rail assembly 300 to a horizontal position.

[0130] In this embodiment, two risers 610 serve as the vertical support structure of the support assembly 600, located on either side of the guide rail assembly 300. One end of each riser 610 has a through hole and is connected to the support member 320 of the guide rail assembly 300 via bolts and nuts, ensuring the stability and reliability of the guide rail assembly 300. A horizontal pipe 620 is positioned between the two risers 610 to connect them, enhancing the stability of the support assembly 600. This not only makes the support assembly 600 more robust and durable but also optimizes its stress distribution, reducing deformation and damage caused by uneven stress.

[0131] The other end of the riser 610 is equipped with an adjusting circular plate 630, which has a threaded through hole in its center. By engaging the bolt with the threaded through hole, the height of the support assembly 600 can be easily adjusted, thereby achieving precise adjustment of the horizontal position of the guide rail assembly 300. This not only improves the flexibility and accuracy during assembly and disassembly but also ensures the stability and reliability of the guide rail assembly 300 in its horizontal position.
