Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to an auxiliary system and method for disassembling and assembling a dual-wheel milling air-lift telescopic slag discharge pipe. Background Technology

[0002] Twin-wheel trenching machines are one of the core pieces of equipment in diaphragm wall construction, widely used in large-scale projects such as water conservancy and hydropower construction, urban subway construction, and high-rise building foundation treatment in rock strata and complex formations. During operation, the large amount of rock debris generated by the milling wheels cutting the rock in the trench mixes with soil and water to form slurry. This slurry and sediment must be promptly discharged to the ground via an air-lift telescopic slag discharge pipe to ensure trenching accuracy and construction efficiency. Therefore, the air-lift telescopic slag discharge pipe is a key component of the twin-wheel trenching machine's slag discharge system, and its ease of assembly and disassembly and safety directly affect the overall construction progress and operational safety.

[0003] Currently, the disassembly and assembly of twin-wheel milling air-lift telescopic slag discharge pipes mainly rely on manual labor in conjunction with large auxiliary equipment such as cranes and forklifts, and there is no dedicated disassembly and assembly auxiliary system. Due to the characteristics of the slag discharge pipes—long length, heavy weight, and easy adhesion of mud to the surface—and the fact that construction sites are mostly open-air with poor ground flatness, the existing disassembly and assembly methods have many defects and shortcomings, as detailed below:

[0004] Firstly, the disassembly and assembly process is inefficient and labor-intensive. During the disassembly of the slag discharge pipes, manual labor is required to control the lowering speed and posture of the pipes with the help of ropes to prevent them from being damaged by impacts. After disassembly, the pipes must be manually moved one by one to the designated storage area and neatly arranged. Similarly, during installation, manual labor is required in conjunction with a crane to lift the pipes one by one to the installation position, adjust and align them before connecting them. The entire process requires a large amount of manpower and the operation procedures are cumbersome, which seriously affects the construction progress.

[0005] Secondly, the operation is unsafe and prone to accidents. The slag discharge pipe is heavy, and during manual pulling and handling, uneven force or rope slippage can easily cause the pipe to fall or overturn, resulting in equipment damage or personal injury. At the same time, when large equipment such as cranes are operating in confined construction sites, there are problems such as limited operating space and difficulty in avoiding obstacles, which further increases the risk of operation. Moreover, working at heights or dragging on the ground can also easily cause safety hazards such as collisions and scratches to personnel.

[0006] Thirdly, poor storage standards can easily lead to equipment damage. Disassembled slag discharge pipes are often simply piled on the ground without proper support structures. Uneven ground and debris accumulation at the construction site make these pipes prone to deformation and corrosion, and the mud adhering to their surfaces is difficult to clean. Long-term storage shortens the lifespan of the pipes. Furthermore, the haphazardly piled slag discharge pipes occupy significant construction space, hindering subsequent construction processes. Re-installation requires rearranging the pipes, further reducing operational efficiency.

[0007] Fourth, existing auxiliary equipment suffers from poor adaptability and insufficient versatility. Existing equipment such as cranes and forklifts used for disassembling and assembling slag discharge pipes are not specifically designed for the structural characteristics of twin-wheel milling air-lift telescopic slag discharge pipes. During disassembly and assembly, it is difficult to accurately control the position and orientation of the slag discharge pipe, easily leading to collisions at the pipe interfaces and damage to seals, affecting the connection and sealing of the slag discharge pipe. This can potentially cause mud leakage during the slag discharge process, impacting the construction environment and slag discharge efficiency. Furthermore, the purchase and use costs of such large equipment are high, making it uneconomical for small and medium-sized construction projects. It also lacks flexibility in complex construction sites, making it difficult to meet the demands for efficient disassembly and assembly.

[0008] Although some auxiliary structures exist in the existing technology for the components related to dual-wheel milling, such as slag discharge pipe fixing brackets and hose winch mechanisms, their main function is to fix the slag discharge pipe or release the hose by winding. They cannot solve the core problems such as storage, transition, and attitude control during the disassembly and assembly of the slag discharge pipe. Moreover, their structure is complex and their adaptability is limited, so they cannot be directly applied to the disassembly and assembly of air-lift telescopic slag discharge pipes.

[0009] In summary, the current disassembly and assembly operations of twin-wheel milling air-lift telescopic slag discharge pipes suffer from low efficiency, high labor intensity, poor safety, easy equipment damage, and insufficient adaptability of auxiliary equipment. These problems severely restrict the construction efficiency and operational safety of twin-wheel milling machines, failing to meet the high-efficiency, safe, and convenient construction requirements of large-scale projects. Therefore, developing a twin-wheel milling air-lift telescopic slag discharge pipe disassembly and assembly auxiliary system that enables rapid disassembly and assembly, standardized storage, and safe transition of slag discharge pipes, while possessing a simple structure and strong adaptability, has become a pressing technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0010] In order to solve the technical problems existing in the prior art, this application provides a dual-wheel milling air-lift telescopic slag discharge pipe disassembly and assembly auxiliary system machine and its installation method.

[0011] To achieve the above objectives, the technical solution adopted in this application is: a dual-wheel milling air-lift telescopic slag discharge pipe disassembly and assembly auxiliary system, comprising:

[0012] A loading and unloading transition structure for receiving or discharging slag through a slag discharge pipe. The slag discharge pipe loading and unloading transition structure includes a base and a slider. The base has a groove for accommodating the sliding of the slider, and the slider is slidably disposed in the groove.

[0013] A storage mechanism for storing slag discharge pipes includes a crossbeam for supporting the slag discharge pipe and a lifting support for supporting the crossbeam. The crossbeam can rotate around the base. A lifting support is installed at the end of the crossbeam away from the base. The lifting support is used to adjust the crossbeam to be in a horizontal state or a downward tilting state. A lifting guide plate is provided on the crossbeam. The lifting guide plate is configured to push the slag discharge pipe upward at an angle to drive the slag discharge pipe from the storage position of the crossbeam to the slag discharge pipe loading and unloading transition structure.

[0014] The unloading auxiliary mechanism includes a winch for pulling the slider, the winch is located at the end of the base, and the winch and the slider are connected by a cable;

[0015] The storage mechanism includes two states: disassembly and installation. When the slag discharge pipe is disassembled, the crossbeam retracts and tilts downward through the lifting support. The disassembled slag discharge pipe rolls down along the tilting direction of the crossbeam under its own weight and is stored side by side on the crossbeam along the length direction.

[0016] When installing the slag discharge pipe, the lifting guide plate is lifted and rotated upwards, and the slag discharge pipe is slid and sent to the slag discharge pipe loading and unloading transition structure under its own gravity.

[0017] In some embodiments of the present invention, the crossbeam has an opening for accommodating a lifting guide plate, one end of the lifting guide plate is rotatably disposed at the end of the crossbeam, and one end of the lifting guide plate is hinged to the hinge joint between the crossbeam and the base.

[0018] In some embodiments of the present invention, the slider includes a slide block, an adjustment seat that can rotate around the slide block, and a wheel that is rotatably disposed in the slide groove. The adjustment seat can rotate freely according to the slag discharge pipe assembly / disassembly angle, and the wheel is disposed on the slide block.

[0019] In some embodiments of the present invention, the slide is provided with a positioning plate for positioning the end of the slag discharge pipe, and the slide is provided with an arc-shaped groove adapted to the slag discharge pipe. The positioning plate is located on one side of the arc-shaped groove, and the slag discharge pipe can abut against the positioning plate.

[0020] In some embodiments of the present invention, the base is provided with a pushing unit for pushing the slag discharge pipe to the storage mechanism. The pushing unit includes a pushing rod and a pushing plate. The pushing rod is disposed on the base, and the pushing plate is disposed at the output end of the pushing rod. The pushing plate pushes the slag discharge pipe of the loading and unloading transition structure to the storage mechanism under the drive of the pushing rod.

[0021] In some embodiments of the present invention, a first drive rod is provided between the lifting guide plate and the crossbeam, and the two ends of the first drive rod are respectively hinged to the lifting guide plate and the crossbeam. The lifting support includes a fixed sliding sleeve and a sliding column slidably disposed in the fixed sliding sleeve. The two ends of the second drive rod are respectively hinged to the fixed sliding sleeve and the sliding column.

[0022] This invention also provides a method for disassembling and assembling a dual-wheel milling air-lift telescopic slag discharge pipe, including slag discharge pipe disassembly steps and slag discharge pipe installation steps:

[0023] The disassembly steps for the slag discharge pipe include:

[0024] S101: Control the slider to slide along the groove of the base to the end of the base away from the winch, lift the slag discharge pipe to be disassembled to the working position, the slag discharge pipe is in a vertical state, place one end of the slag discharge pipe in the arc groove of the slider seat, and make the slag discharge pipe abut against the positioning plate, adjust the adjusting seat of the slider to make the abutment angle between the adjusting seat and the slag discharge pipe match.

[0025] S102: Start the winch. The winch pulls the slider through the cable, so that the slider slides along the groove towards the end closer to the winch through the wheel. The slider drives the slag discharge pipe to move synchronously, so that the slag discharge pipe gradually tilts from a vertical state to an inclined state, and finally becomes a horizontal state.

[0026] S103: Start the pushing unit. The pushing rod drives the pushing plate to extend. The pushing plate pushes the horizontal slag discharge pipe from the loading and unloading transition structure to the crossbeam of the storage mechanism. The second driving rod slowly tilts the crossbeam from horizontal to inclined. The slag discharge pipe slides along the downward tilting crossbeam under its own gravity until it is placed side by side on the crossbeam along the length direction and stored, thus completing the disassembly of the slag discharge pipe.

[0027] The installation steps for the slag discharge pipe include:

[0028] S201: The second drive rod of the lifting support drives the sliding column to extend along the fixed sliding sleeve, which drives the crossbeam to return from the downward tilting state to the horizontal state. Then, the first drive rod drives the lifting guide plate to lift and tilt upward around the hinge point. The lifting guide plate extends out from the opening of the crossbeam and pushes against the slag discharge pipes stored side by side on the crossbeam. Under the pushing force of the lifting guide plate and its own weight, the slag discharge pipe to be installed slides along the crossbeam to the slider slide seat of the loading and unloading transition structure, and the slag discharge pipe abuts against the positioning plate and is placed in the arc groove.

[0029] S202: Under the action of the hoisting equipment, the slag discharge pipe to be installed is slowly lifted. The slag discharge pipe gradually tilts from horizontal to vertical. The slider moves freely along the slide groove, so that the slag discharge pipe on the slider moves to the docking position that is compatible with the hoisting mechanism. At the same time, the adjusting seat of the slider is adjusted so that the slag discharge pipe is in a posture that is easy to hoist.

[0030] S203: The slag discharge pipe on the loading and unloading transition structure is lifted by the hoisting mechanism and precisely aligned with the interface of the double-wheel milling air-lift telescopic slag discharge pipe to complete the installation of the slag discharge pipe. At the same time, the slider is controlled to slide and reset, the guide plate is lifted and stored in the opening of the crossbeam, and the lifting support is adjusted to the horizontal state of the crossbeam to prepare for the installation of the next slag discharge pipe.

[0031] In some embodiments of the present invention, in step 103 above, after the slag discharge pipe moves to the end of the crossbeam away from the base, the second drive rod is driven to reset the crossbeam horizontally. When the next slag discharge pipe reaches the crossbeam, the crossbeam is driven to tilt slowly so that the next slag discharge pipe slowly abuts against the previous slag discharge pipe.

[0032] In some embodiments of the present invention, in step 201 above, the lifting tilt angle of the lifting guide plate is precisely controlled by the first drive rod, and the lifting tilt angle is adapted to the conveying requirements of the slag discharge pipe, so that the lifting guide plate always keeps in close contact with the slag discharge pipe, ensuring that the slag discharge pipe slides smoothly to the loading and unloading transition structure. During this process, the lifting support is only responsible for restoring the crossbeam to a horizontal state and does not participate in the lifting action.

[0033] In some embodiments of the present invention, in step 201 above, after the slag discharge pipe slides smoothly to the loading and unloading transition structure, the first drive rod drives the lifting guide plate to reset to the horizontal position. After the slag discharge pipe to be installed on the loading and unloading transition structure is fully loaded, the lifting guide plate is driven again to lift so that the slag discharge pipe automatically slides into the loading and unloading transition structure.

[0034] Beneficial effects:

[0035] 1. The loading / unloading transition structure and storage mechanism of this invention enable integrated operation of slag discharge pipe disassembly, assembly, and storage, eliminating the need for manual labor in conjunction with large equipment such as cranes and forklifts for cumbersome hoisting and handling operations. When disassembling the slag discharge pipe, the crossbeam retracts and tilts downwards via the lifting support. The disassembled slag discharge pipe can roll down along the tilt direction of the crossbeam under its own weight, eliminating the need for manual traction. It can also be stored side-by-side along the length of the crossbeam, saving the step of manual arrangement. When installing the slag discharge pipe, the lifting guide plate on the crossbeam tilts upwards and pushes the slag discharge pipe, smoothly delivering it from the storage position to the loading / unloading transition structure. Combined with the winch of the unloading auxiliary mechanism pulling the slider, rapid loading of the slag discharge pipe is achieved. The entire disassembly and assembly process is simplified and highly automated, significantly reducing manpower input, lowering the labor intensity of operators, and significantly improving construction progress. This solves the problems of low disassembly and assembly efficiency and high labor intensity in existing technologies.

[0036] 2. The coordinated operation of the loading and unloading transition structure, storage mechanism and unloading auxiliary mechanism of the present invention can accurately adapt to air-lift telescopic slag discharge pipes of different lengths and weights, flexibly control the disassembly and assembly posture and storage status of the slag discharge pipe, avoid collisions at the slag discharge pipe interface and damage to the seals, ensure the connection and sealing of the slag discharge pipe, and prevent mud leakage.

[0052] Example 1

[0053] Please refer to Figures 1-6 This embodiment provides an auxiliary system for disassembling and assembling a dual-wheel milling air-lift telescopic slag discharge pipe, including:

[0054] The loading and unloading transition structure for receiving or discharging slag from the slag discharge pipe includes a base 1 and a slider 2. The base 1 has a groove 3 for accommodating the sliding of the slider 2, and the slider 2 is slidably disposed in the groove 3.

[0055] It should be noted that the aforementioned loading and unloading transition structure is used to realize the feeding output and unloading reception of the slag discharge pipe, and to build a transition channel between the slag discharge pipe and the storage mechanism and the main body of the twin-wheel milling machine. Specifically, the base 1 serves as the installation foundation and load-bearing body of the entire system, providing a rigid support surface for the sliding of the slider 2, the hinge of the crossbeam 4, and the fixing of the winch 7, ensuring the overall structural stability during tilting, pushing, and storage, and preventing swaying or deformation. The chute 3 is formed on the base 1, providing a linear motion track for the slider 2, constraining the slider 2 to move back and forth only along the length of the base 1, limiting its lateral offset and vertical jump, and ensuring that the movement trajectory of the slag discharge pipe is stable and controllable during tilting. The slider 2 is slidably set in the chute 3. During disassembly: the slider 2 moves to the end of the base 1 away from the winch 7 and receives the lower end of the vertical slag discharge pipe; the winch 7 pulls the slider 2 to slide closer to the side through the cable 15. The slider 2 moves horizontally along the chute 3, driving the slag discharge pipe to rotate synchronously around the upper hoisting point, so that the slag discharge pipe gradually tilts from vertical to horizontal. During installation: the slider 2 receives the slag discharge pipe sent from the storage mechanism and moves it to the hoisting docking position to realize the feeding output.

[0056] A storage mechanism for storing slag discharge pipes includes a crossbeam 4 for supporting the slag discharge pipe and a lifting support 5 for supporting the crossbeam 4. The crossbeam 4 can rotate around the base 1. The lifting support 5 is installed at the end of the crossbeam 4 away from the base 1. The lifting support 5 is used to adjust the crossbeam 4 to be in a horizontal state or a downward tilting state. A lifting guide plate 6 is provided on the crossbeam 4. The lifting guide plate 6 is configured to push the slag discharge pipe upward at an angle to drive the slag discharge pipe from the storage position of the crossbeam 4 to the slag discharge pipe loading and unloading transition structure.

[0057] In this embodiment, the storage mechanism includes a crossbeam 4, a lifting support 5, and a lifting guide plate 6. It utilizes gravity for automatic pipe arrangement and the lifting guide plate 6 for automatic pipe feeding, achieving integrated disassembly, storage, installation, and material feeding. The crossbeam 4 is a long, strip-shaped support component, hinged at one end to the base 1, and can rotate up and down around the base 1 to form a tiltable storage platform. During disassembly, the crossbeam 4 tilts downwards, allowing the slag discharge pipe to roll along its length under its own weight. During installation, the crossbeam 4 returns to a horizontal position, providing stable support for the slag discharge pipe and cooperating with the lifting guide plate 6 to complete material feeding. The crossbeam 4 can simultaneously accommodate multiple slag discharge pipes side-by-side along its length, achieving dense and orderly storage while reducing floor space.

[0058] The lifting support 5 is installed at the end of the crossbeam 4 furthest from the base 1. It is only used to control the crossbeam 4 between a horizontal state and a downward tilting state. Its working principle is as follows: When disassembling the slag discharge pipe: the lifting support 5 retracts, causing the crossbeam 4 to tilt downward around the base 1, forming a downward slope guide surface, allowing the slag discharge pipe to roll down by its own weight and arrange itself in sequence; before installing the slag discharge pipe: the lifting support 5 extends, raising the crossbeam 4 from the tilted state to a horizontal state, providing a stable reference for the lifting guide plate 6 to deliver the pipe, and preventing the slag discharge pipe from rolling disorderly during the feeding process. The lifting support 5 is used for overall tilt angle adjustment and does not participate in the pushing action of the slag discharge pipe. Its functions are clear and do not interfere with each other.

[0059] Furthermore, the aforementioned lifting guide plate 6 is installed on the crossbeam 4, which is a structure for automatically outputting stored upward-moving materials. The working principle is as follows:

[0060] During disassembly and storage: the lifting guide plate 6 is in a retracted or low position, flush with the surface of the crossbeam 4, and does not obstruct the slag discharge pipe from rolling down and arranging along the crossbeam 4; during installation and feeding: the lifting guide plate 6 is tilted upward to form an upward pushing slope, and the outermost slag discharge pipe is lifted and guided towards the slider 2 by the tilting lifting action; under the combined action of the pushing force of the lifting guide plate 6 and its own gravity, the slag discharge pipe slides along the slope to the slider 2 position of the loading and unloading transition structure, realizing automatic feeding and output without the need for manual pipe pushing or tucking.

[0061] The unloading auxiliary mechanism includes a winch 7 for pulling the slider 2. The winch 7 is located at the end of the base 1, and the winch 7 and the slider 2 are connected by a cable 15. The winch 7 is fixed to the end of the base 1, providing a stable and controllable pulling force. The cable 15 is wound up and down by forward and reverse rotation, thereby dragging the slider 2 to move back and forth within the chute 3. The winch 7 can control the winding and pulling speed of the cable 15, so that the slider 2 moves at a uniform speed, ensuring that the slag discharge pipe slowly tilts from vertical to horizontal, avoiding impact, collision, and swinging. The cable 15 connects the winch 7 and the slider 2, converting the rotational driving force of the winch 7 into the linear traction force of the slider 2. The cable 15 is always in a taut state, ensuring that the slider 2 responds promptly and without lag, achieving a smooth and controllable tilting process.

[0062] The storage mechanism includes two states: disassembly and installation. When the slag discharge pipe is disassembled, the crossbeam 4 retracts and tilts downward through the lifting support 5. The disassembled slag discharge pipe rolls down along the tilting direction of the crossbeam 4 under its own weight and is placed side by side on the crossbeam 4 along the length direction for storage.

[0063] The slag discharge pipe is lifted and kept vertical by the hoisting mechanism, with its lower end abutting against the slider 2. The winch 7 pulls the slider 2 to move inward along the slide 3, and the slider 2 drives the lower end of the slag discharge pipe to move horizontally, so that the slag discharge pipe gradually tilts from vertical to inclined, and finally flattens. The lifting support 5 retracts, so that the crossbeam 4 tilts downward, forming a downhill guide. The pushing mechanism pushes the flattened slag discharge pipe onto the crossbeam 4. Under its own weight, the slag discharge pipe rolls along the inclined crossbeam 4 and is then placed side by side and neatly stored on the crossbeam 4 along its length. Multiple slag discharge pipes repeat the above process in sequence to achieve continuous and automated disassembly and storage.

[0064] When installing the slag discharge pipe, the lifting guide plate 6 is lifted and rotated upwards, and the slag discharge pipe to be installed slides under its own weight to the slag discharge pipe loading and unloading transition structure. Specifically, the aforementioned lifting support 5 extends, restoring the crossbeam 4 from an inclined position to a horizontal position; the lifting guide plate 6 is lifted upwards at an incline, forming an upward and outward pushing force on the slag discharge pipe stored on the crossbeam 4; under the pushing force of the lifting guide plate 6 and its own weight, the slag discharge pipe slides along the guide to the slider 2 of the loading and unloading transition structure; the slider 2 moves to the docking position, and the hoisting mechanism lifts the slag discharge pipe and docks it with the double-wheel milling body for installation; the lifting guide plate 6 falls back to its original position, completing one loading and output cycle.

[0065] Please refer to Figure 1 , Figure 2 and Figure 5 Furthermore, the aforementioned crossbeam 4 has an opening 8 for accommodating the lifting guide plate 6. One end of the lifting guide plate 6 is rotatably disposed at the end of the crossbeam 4, and the other end of the lifting guide plate 6 is hinged to the hinge joint between the crossbeam 4 and the base 1.

[0066] In this embodiment, an opening 8 is provided along the length of the crossbeam 4. The shape and size of the opening 8 match the lifting guide plate 6, allowing the lifting guide plate 6 to be stored and concealed when not in operation. During the disassembly and storage of the slag discharge pipe, the lifting guide plate 6 is completely stored inside the opening 8, ensuring that the upper surface of the lifting guide plate 6 is flush with or slightly lower than the supporting surface of the crossbeam 4, preventing any protruding obstacles and ensuring that the slag discharge pipe can smoothly roll along the crossbeam 4 under its own weight without jamming, bumping, or jumping. The opening 8 provides rotational space for the lifting guide plate 6 to be flipped and lifted upwards, allowing it to tilt upwards around the hinge point without structural interference with the crossbeam 4 body, ensuring that the lifting action can be performed smoothly. The sidewall of the opening 8 provides lateral constraint on the storage position of the lifting guide plate 6, preventing it from shifting left or right in the stored state and ensuring that it remains in the central area where it can stably push against the slag discharge pipe.

[0067] Please refer to Figure 1 and Figure 6The aforementioned slider 2 includes a slide seat 201, an adjustment seat 202 that can rotate around the slide seat 201, and a wheel 203 that is rotatably disposed in the slide groove 3. The adjustment seat 202 can rotate freely according to the slag discharge pipe assembly / disassembly angle, and the wheel 203 is disposed on the slide seat 201.

[0068] In this embodiment, the slider 2 includes a slide seat 201, an adjusting seat 202, and a wheel 203. The slide seat 201 serves as the main bearing and is used to install the adjusting seat 202 and the wheel 203. The adjusting seat 202 is rotatably mounted on the slide seat 201 and can adaptively rotate freely according to the vertical, tilt, and horizontal posture changes of the slag discharge pipe during disassembly and assembly, always maintaining close contact and support with the slag discharge pipe to avoid angular interference and pipe damage. The wheel 203 is rotatably mounted on the slide seat 201 and cooperates with the groove 3 of the base 1, converting the sliding friction between the slide seat 201 and the groove 3 into rolling friction, reducing the moving resistance of the slider 2, and guiding and limiting the movement of the slide seat 201 to ensure that the slider 2 moves smoothly along the groove 3, thereby realizing the smooth conversion and precise conveying of the slag discharge pipe posture.

[0069] Please refer to Figure 6 The slide 201 is provided with a positioning plate 9 for positioning the end of the slag discharge pipe. The slide 201 is provided with an arc-shaped groove 10 adapted to the slag discharge pipe. The positioning plate 9 is located on one side of the arc-shaped groove 10, and the slag discharge pipe can abut against the positioning plate 9.

[0070] In this embodiment, the aforementioned arc-shaped groove 10 is formed on the upper surface of the slide 201, and its arc-shaped contour is perfectly matched with the curvature of the outer wall of the slag discharge pipe, ensuring that the end of the slag discharge pipe can be embedded in the groove to achieve close support. The position of the arc-shaped groove 10 corresponds to the installation position of the adjusting seat 202, and can work together with the adjusting seat 202 to support the slag discharge pipe. When the end of the slag discharge pipe is placed in the arc-shaped groove 10, the inner wall of the arc-shaped groove 10 is fully in contact with the outer wall of the slag discharge pipe, transforming the weight of the end of the slag discharge pipe and the impact force during the tilting process from point contact to surface contact, effectively dispersing the force, avoiding the outer wall of the slag discharge pipe from being squeezed and worn due to local stress concentration, and protecting the end interface of the slag discharge pipe.

[0071] It should be noted that the aforementioned positioning plate 9 is fixedly installed on the slide block 201, located on one side of the arc groove 10, and has a plate-like structure perpendicular to the upper surface of the slide block 201. Its height is slightly higher than the opening of the arc groove 10, and it can abut against the end face or outer wall of the slag discharge pipe without affecting the placement and rotation of the slag discharge pipe.

[0072] Further, please refer to Figures 1-3The base 1 is provided with a pushing unit 11 for pushing the slag discharge pipe to the storage mechanism. The pushing unit 11 includes a pushing rod and a pushing plate 12. The pushing rod is disposed on the base 1, and the pushing plate 12 is disposed at the output end of the pushing rod. The pushing plate 12 pushes the slag discharge pipe of the loading and unloading transition structure to the storage mechanism under the drive of the pushing rod.

[0073] In this embodiment, the push rod, as a power actuator, is fixed on the base 1 to provide a stable driving force for the pushing action and can accurately control the extension length and pushing speed of the push plate 12. The push plate 12, as a component that directly acts on the slag discharge pipe, is used to push the slag discharge pipe to the storage mechanism. The extension stroke of the push rod is preset to be the distance from the slider 2 of the loading and unloading transition structure to the crossbeam 4 of the storage mechanism, ensuring that the push plate 12 can accurately push the slag discharge pipe to the preset storage position of the crossbeam 4 without the need for manual adjustment.

[0074] Further, please refer to Figure 4 A first drive rod 13 is provided between the lifting guide plate 6 and the crossbeam 4. The two ends of the first drive rod 13 are respectively hinged to the lifting guide plate 6 and the crossbeam 4. The lifting support 5 includes a fixed sliding sleeve 501 and a sliding column 502 slidably disposed in the fixed sliding sleeve 501. The two ends of the second drive rod 14 are respectively hinged to the fixed sliding sleeve 501 and the sliding column 502.

[0075] In this embodiment, the first drive rod 13 is hinged at both ends to the lifting guide plate 6 and the crossbeam 4, respectively. It employs a telescopic rod structure, which does not interfere with the retraction and lifting action of the lifting guide plate 6. It can extend and retract synchronously with the rotation of the lifting guide plate 6, achieving precise angle control of the lifting guide plate 6. The first drive rod 13 can precisely control its extension and retraction, thereby adjusting the lifting tilt angle of the lifting guide plate 6. During installation and loading, based on the size, weight, and conveying requirements of the slag discharge pipe, the tilt angle of the lifting guide plate 6 is adjusted to a preset range by controlling the extension and retraction length of the first drive rod 13. This ensures that the lifting guide plate 6 can smoothly push against the slag discharge pipe, while avoiding excessive angles that could cause the slag discharge pipe to slide too quickly and detach from the crossbeam 4, and excessive angles that would prevent effective pushing of the slag discharge pipe. This achieves precise conveying of the slag discharge pipe to the loading and unloading transition structure.

[0076] It should be noted that the aforementioned lifting support 5 is installed at the end of the crossbeam 4 away from the base 1, and is used to support the crossbeam 4 and adjust its tilt angle. It includes a fixed sliding sleeve 501 and a sliding column 502. The sliding column 502 is slidably disposed in the fixed sliding sleeve 501 to form a telescopic support structure. The two ends of the second drive rod 14 are respectively hinged to the fixed sliding sleeve 501 and the sliding column 502. It adopts a telescopic drive structure and, together with the fixed sliding sleeve 501 and the sliding column 502, constitutes the power adjustment mechanism of the lifting support 5. It is only used to adjust the crossbeam 4 between the horizontal state and the downward tilting state.

[0077] Specifically, the aforementioned fixed sliding sleeve 501, sliding column 502, and second drive rod 14 work together to form a complete adjustment mechanism for the lifting support 5. The second drive rod 14 provides power, the fixed sliding sleeve 501 provides guidance and support, and the sliding column 502 adjusts its height through extension and retraction, thereby causing the tilt angle of the crossbeam 4 to change. Its working process is precisely adapted to the system operating conditions: during disassembly, the crossbeam 4 tilts downwards, facilitating the slag discharge pipe to roll and arrange itself under its own weight; during installation, the crossbeam 4 is horizontal, facilitating the lifting guide plate 6 to push the slag discharge pipe. At the same time, the hinge structure of the second drive rod 14 can adapt to the rotation posture of the crossbeam 4, avoiding motion interference and ensuring that the adjustment action of the lifting support 5 is smooth and reliable. It forms a coordinated linkage with the first drive rod 13, lifting guide plate 6, pushing unit 11, and other components, ensuring the smooth operation of the entire disassembly and assembly system.

[0078] Example 2

[0079] Please refer to Figure 7 This embodiment provides a method for disassembling and assembling a dual-wheel milling air-lift telescopic slag discharge pipe, including a slag discharge pipe disassembly step and a slag discharge pipe installation step: The slag discharge pipe disassembly step includes:

[0080] S101: Control the slider 2 to slide along the groove 3 of the base 1 to the end of the base 1 away from the winch 7, lift the slag discharge pipe to be disassembled to the working position, the slag discharge pipe is in a vertical state, place one end of the slag discharge pipe in the arc groove 10 of the slider 2 slide seat 201, and make the slag discharge pipe abut against the positioning plate 9, adjust the adjusting seat 202 of the slider 2 to make the abutment angle between the adjusting seat 202 and the slag discharge pipe match.

[0081] Specifically, the aforementioned slider 2 slides along the groove 3 via the wheel 203, which converts sliding friction into rolling friction, reducing the resistance to movement of the slider 2 and ensuring that the slider 2 moves smoothly to the preset position. The arc groove 10 is adapted to the outer wall of the slag discharge pipe, achieving a close fit and radial limit at the end of the slag discharge pipe. The positioning plate 9 achieves axial limit of the slag discharge pipe. Together, they accurately position the slag discharge pipe on the slide 201, preventing the slag discharge pipe from shifting. The adjusting seat 202 can rotate freely around the slide 201, adapting to the contact angle of the vertical state of the slag discharge pipe, ensuring that the slag discharge pipe fits tightly with the slide 201 and the positioning plate 9, providing a stable reference for subsequent tilting actions, while avoiding pipe damage caused by rigid hard contact.

[0082] S102: Start the winch 7. The winch 7 pulls the slider 2 through the cable 15, so that the slider 2 slides along the slide groove 3 through the wheel 203 towards the end close to the winch 7. The slider 2 drives the slag discharge pipe to move synchronously, so that the slag discharge pipe gradually tilts from a vertical state to an inclined state, and finally becomes a horizontal state.

[0083] Specifically, the winch 7 provides stable traction force, which is transmitted to the slider 2 through the cable 15, driving the slider 2 to move linearly along the groove 3; the wheel 203 rolls along the groove 3, further reducing the moving resistance of the slider 2, ensuring that the slider 2 moves at a uniform speed, and avoiding the slider 2 from jamming and causing the slag discharge pipe to tilt unbalanced; during the movement of the slider 2, the lower end of the slag discharge pipe moves horizontally in sync, and the upper end of the slag discharge pipe remains fixed in position under the constraint of the hoisting mechanism, thereby realizing the smooth tilting of the slag discharge pipe from vertical to horizontal. The adjusting seat 202 rotates synchronously and adaptively with the tilting angle of the slag discharge pipe, always in contact with the slag discharge pipe, avoiding jamming or slippage during the tilting process of the slag discharge pipe; at the same time, the sliding stroke of the slider 2 is precisely matched with the tilting angle of the slag discharge pipe, ensuring smooth posture conversion of the slag discharge pipe without impact or deviation.

[0084] S103: Start the pushing unit 11, the pushing rod drives the pushing plate 12 to extend, the pushing plate 12 pushes the horizontal slag discharge pipe from the loading and unloading transition structure to the crossbeam 4 of the storage mechanism, and the second driving rod 14 slowly tilts the crossbeam 4 from horizontal to inclined. The slag discharge pipe slides along the downward tilting crossbeam 4 under its own gravity until it is placed side by side on the crossbeam 4 along the length direction and stored, thus completing the disassembly of the slag discharge pipe.

[0085] The push rod provides stable pushing power, and the push plate 12 fits against the outer wall of the slag discharge pipe to ensure uniform force during pushing. The pushing direction is consistent with the length direction of the crossbeam 4, achieving precise pushing of the slag discharge pipe and avoiding deviation or collision during the pushing process. The second drive rod 14 drives the sliding column 502 to retract, causing the crossbeam 4 to tilt downward around the base 1, forming a downhill guide surface. Under the action of its own gravity, the slag discharge pipe slides along the tilt direction of the crossbeam 4, achieving orderly rolling without additional power. The tilt angle of the crossbeam 4 is precisely controlled by the second drive rod 14 to ensure that the rolling speed of the slag discharge pipe is stable, avoiding collisions and damage caused by excessive speed. At the same time, it ensures that multiple slag discharge pipes are neatly arranged and abutted along the length direction of the crossbeam 4, achieving orderly storage. The push unit 11 and the lifting support 5 work together to form a closed loop of pushing, tilt angle adjustment, and rolling storage, improving the automation level of the dismantling operation and reducing manual intervention.

[0086] The installation steps for the slag discharge pipe include:

[0087] S201: The second drive rod 14 of the lifting support 5 drives the sliding column 502 to extend along the fixed sliding sleeve 501, which drives the crossbeam 4 to return from the downward tilting state to the horizontal state. Then, the first drive rod 13 drives the lifting guide plate 6 to lift and tilt upward around the hinge point. The lifting guide plate 6 extends out from the opening 8 of the crossbeam 4 and pushes against the slag discharge pipes stored side by side on the crossbeam 4. Under the pushing force of the lifting guide plate 6 and its own weight, the slag discharge pipe to be installed slides along the crossbeam 4 to the slider 2 slide block 201 of the loading and unloading transition structure, and the slag discharge pipe abuts against the positioning plate 9 and is placed in the arc groove 10.

[0088] Specifically, the second drive rod 14 provides power to drive the sliding column 502 to extend along the fixed sliding sleeve 501, thereby lifting the crossbeam 4 upwards and resetting it to a horizontal state, providing a stable support surface for the conveying of the slag discharge pipe; the first drive rod 13 drives the lifting guide plate 6 to tilt and rotate upwards, with a precise and controllable lifting angle, ensuring that the lifting guide plate 6 fits against the outer wall of the slag discharge pipe, providing a stable pushing force. At the same time, the slag discharge pipe slides along the crossbeam 4 under the action of its own gravity component. The two work together to achieve smooth conveying of the slag discharge pipe, avoiding jamming or slippage of the slag discharge pipe; the arc groove 10 and the positioning plate 9 again play a radial and axial limiting role, accurately positioning the slag discharge pipe on the slider 2, preparing for subsequent docking and hoisting; the lifting guide plate 6 is housed in the opening 8 of the crossbeam 4, without obstructing the sliding of the slag discharge pipe, and adapting to the support requirements of the horizontal state of the crossbeam 4.

[0089] S202: Under the action of the hoisting equipment, the slag discharge pipe to be installed is slowly lifted. The slag discharge pipe gradually tilts from horizontal to vertical. The slider 2 moves freely along the slide groove 3, so that the slag discharge pipe on the slider 2 moves to the docking position that is compatible with the hoisting mechanism. At the same time, the adjusting seat 202 of the slider 2 is adjusted so that the slag discharge pipe is in a posture that is easy to hoist.

[0090] Specifically, the aforementioned hoisting mechanism provides a stable hoisting force, slowly lifting the slag discharge pipe to achieve a smooth transition from a horizontal to an inclined and vertical state, avoiding swaying and collision of the slag discharge pipe during hoisting; the slider 2 can move freely along the slide groove 3 to adapt to the posture changes of the slag discharge pipe during hoisting, ensuring that the slag discharge pipe moves to the optimal position for hoisting and docking, reducing the difficulty of hoisting alignment; the adjusting seat 202 adapts to the hoisting posture of the slag discharge pipe, synchronously rotating to adjust the angle, always fitting and supporting the slag discharge pipe, preventing displacement and slippage of the slag discharge pipe during the hoisting transition, ensuring the stability of the slag discharge pipe posture, and facilitating precise docking with the hoisting mechanism.

[0091] S203: The slag discharge pipe on the loading and unloading transition structure is lifted by the hoisting mechanism and precisely aligned with the interface of the double-wheel milling air-lift telescopic slag discharge pipe to complete the installation of the slag discharge pipe. At the same time, the slider 2 is controlled to slide and reset, the lifting guide plate 6 is retracted into the opening 8 of the crossbeam 4, and the lifting support 5 is adjusted to the horizontal state of the crossbeam 4 to prepare for the installation of the next slag discharge pipe.

[0092] In this embodiment, the hoisting mechanism precisely controls the hoisting height and posture of the slag discharge pipe, achieving precise alignment with the dual-wheel milling interface and avoiding installation failure or interface damage caused by misalignment. After the slag discharge pipe is installed, the slider 2 slides back to its initial position, preparing for the delivery of the next slag discharge pipe. The first drive rod 13 retracts, driving the lifting guide plate 6 back into the opening 8 of the crossbeam 4, preventing the lifting guide plate 6 from protruding and affecting the storage and delivery of subsequent slag discharge pipes. The second drive rod 14 keeps the crossbeam 4 in a horizontal state, providing stable support for the lifting and delivery of the next slag discharge pipe. All components work together to reset, forming a cycle from installation to reset, realizing continuous installation operations, further improving installation efficiency and reducing manual operation load.

[0093] Furthermore, in step 103 above, after the slag discharge pipe moves to the end of the crossbeam 4 away from the base 1, the second drive rod 14 is driven to reset the crossbeam 4 horizontally. When the next slag discharge pipe arrives at the crossbeam 4, the crossbeam 4 is driven to tilt slowly so that the next slag discharge pipe slowly comes into contact with the previous slag discharge pipe.

[0094] Specifically, after the slag discharge pipe is pushed onto the crossbeam 4 by the pushing unit 11, it slides along the inclined crossbeam 4 under the action of its own gravity until it moves to the end of the crossbeam 4 away from the base 1, that is, the extreme position of the end of the crossbeam 4. At this time, the slag discharge pipe has completed the initial placement. If the crossbeam 4 is kept in an inclined state, it is easy to cause the subsequent slag discharge pipe to directly collide with the already placed slag discharge pipe when it rolls down. Therefore, the lifting support 5 needs to be driven by the second drive rod 14 to achieve the horizontal reset adjustment of the crossbeam 4: the second drive rod 14 is the power core of the lifting support 5. Its output end extends and pushes the sliding column 502 to slide upward along the fixed sliding sleeve 501. The sliding column 502 drives the end of the crossbeam 4 away from the base 1 to rise synchronously until the crossbeam 4 is adjusted to a horizontal state. At this time, the slag discharge pipe that has been placed at the end of the crossbeam 4 remains stable under the support of the horizontal crossbeam 4, avoiding the slag discharge pipe from continuing to slide or deviate due to the continuous tilting of the crossbeam 4, reserving a reasonable sliding space for the storage of the next slag discharge pipe, and preventing the slag discharge pipe that has been placed from tilting due to the lack of horizontal support.

[0095] After the next slag discharge pipe is pushed onto the crossbeam 4 by the pushing unit 11, the second drive rod 14 begins to retract, pulling the sliding column 502 downward along the fixed sliding sleeve 501. The end of the crossbeam 4 away from the base 1 sinks accordingly, gradually returning to its downward tilted state. At this time, the next slag discharge pipe, under the action of its own gravity, slowly slides along the tilted crossbeam 4. During the sliding process, its end gradually approaches the previously stored slag discharge pipe until the two smoothly come into contact. Throughout the process, the extension and retraction speed of the second drive rod 14 is precisely controlled, which avoids the crossbeam 4 tilting too fast, causing the slag discharge pipe to slide and accelerate, thus resulting in a rigid collision with the previous slag discharge pipe and causing damage to the pipe; and also prevents the crossbeam 4 tilting too slowly, causing the slag discharge pipe to remain stuck in the middle of the crossbeam 4, making effective contact and storage impossible.

[0096] Furthermore, in step 201 above, the lifting tilt angle of the lifting guide plate 6 is precisely controlled by the first drive rod 13, and the lifting tilt angle is adapted to the conveying requirements of the slag discharge pipe, so that the lifting guide plate 6 always keeps in close contact with the slag discharge pipe, ensuring that the slag discharge pipe slides smoothly to the loading and unloading transition structure. During this process, the lifting support 5 is only responsible for resetting the crossbeam 4 to a horizontal state and does not participate in the lifting action.

[0097] Specifically, the aforementioned lifting support 5 is used to reset the posture of the crossbeam 4 during this process and does not participate in the lifting action of the slag discharge pipe. The second drive rod 14 of the lifting support 5 serves as a power component, driving the sliding column 502 to extend along the fixed sliding sleeve 501. The extension and retraction of the sliding column 502 changes the overall height of the lifting support 5, thereby driving the crossbeam 4 from its disassembled downward tilted state to a smooth reset to a horizontal state. After the crossbeam 4 is horizontally reset, it provides a stable support benchmark for the sliding conveying of the slag discharge pipe, preventing premature sliding and loss of posture of the slag discharge pipe due to the tilt of the crossbeam 4. At the same time, it reserves reasonable movement space for the lifting guide plate 6 to lift, ensuring that the lifting guide plate 6 can extend smoothly from the opening 8 of the crossbeam 4 without structural interference. During this process, the lifting support 5 only undertakes the horizontal reset support function of the crossbeam 4 and does not participate in any lifting or pushing action of the slag discharge pipe. The division of functions is clear, avoiding conflicts with the action of the lifting guide plate 6 and ensuring an orderly operation process.

[0098] It should be noted that the first drive rod 13 precisely controls the lifting tilt angle of the lifting guide plate 6 to achieve stable conveying of the slag discharge pipe. The two ends of the first drive rod 13 are respectively hinged to the crossbeam 4 and the lifting guide plate 6. As the dedicated power source for the lifting guide plate 6, its extension and retraction can be precisely adjusted, thereby precisely controlling the upward tilt angle of the lifting guide plate 6 around the hinge point. The lifting tilt angle of the lifting guide plate 6 is not a fixed value, but is flexibly adapted to the conveying requirements of the slag discharge pipe, taking into account the weight and diameter of the slag discharge pipe, as well as the length of the crossbeam 4 and the docking position of the slider 2 slide block 201. Through the extension and retraction adjustment of the first drive rod 13, the lifting guide plate 6 forms a suitable tilting pushing surface, ensuring that the lifting guide plate 6 always remains in close contact with the outer wall of the slag discharge pipe. This precise angle control can provide sufficient thrust to push the slag discharge pipe to slide along the crossbeam 4, while avoiding the slag discharge pipe sliding too fast and getting out of control due to an excessively large angle, or the slag discharge pipe getting stuck on the crossbeam 4 and unable to move due to an insufficient thrust due to an excessively small angle.

[0099] The lifting guide plate 6 and the slag discharge pipe are closely pressed together, and the slag discharge pipe is supported by its own weight to achieve stable conveying: After the lifting guide plate 6 extends out of the opening 8 of the crossbeam 4, its pushing surface is in contact with the outer wall of the slag discharge pipe. Under the drive of the first drive rod 13, a stable pushing force is continuously applied. At the same time, the slag discharge pipe generates a component force that slides along the crossbeam 4 under its own weight. The two forces work together to push the slag discharge pipe to slide smoothly along the horizontal crossbeam 4 until it falls precisely onto the slider 2 slide block 201 of the loading and unloading transition structure, and abuts against the positioning plate 9 and is embedded in the arc groove 10, thus completing the lifting and feeding of the slag discharge pipe. Throughout the process, because the lifting support 5 has reset the crossbeam 4 to a horizontal position, the sliding direction of the slag discharge pipe is stable. The action of the lifting guide plate 6 in contacting and pushing is precisely matched with the sliding trajectory of the slag discharge pipe, effectively avoiding jamming, deviation or collision damage during the sliding of the slag discharge pipe. At the same time, by clarifying the functional division of the lifting support 5, the first drive rod 13 and the lifting guide plate 6, it is ensured that the actions of each component are coordinated and do not interfere with each other, further improving the stability and accuracy of the slag discharge pipe installation and feeding, laying the foundation for the subsequent transition alignment and hoisting installation of the slag discharge pipe.

[0100] Furthermore, in step 201 above, after the slag discharge pipe slides smoothly to the loading and unloading transition structure, the first drive rod 13 drives the lifting guide plate 6 to reset to the horizontal position. After the slag discharge pipe to be installed on the loading and unloading transition structure is fully loaded, the lifting guide plate 6 is driven again to lift so that the slag discharge pipe automatically slides into the loading and unloading transition structure.

[0101] When the slag discharge pipe smoothly slides onto the slider 2 slide block 201 of the loading and unloading transition structure under the combined action of the pushing force of the lifting guide plate 6 and its own gravity, and completes the contact with the positioning plate 9 and the embedding and positioning of the arc groove 10, the first drive rod 13 initiates a retraction action, driving the lifting guide plate 6 to rotate downward around the hinge point to reset until the lifting guide plate 6 returns to a horizontal position and is completely housed in the opening 8 of the crossbeam 4, flush with the support surface of the crossbeam 4. At this time, the lifting guide plate 6 is in a standby state. Its core purpose is to prevent the lifting guide plate 6 from protruding from the surface of the crossbeam 4, so as not to hinder the hoisting and docking operation of the slag discharge pipe on the loading and unloading transition structure, and to prevent accidental collision with the slag discharge pipe during subsequent lifting. At the same time, it reserves a non-interference movement space for the lifting and conveying of the next slag discharge pipe, ensuring the continuity of the operation process.

[0102] During use, after the slag discharge pipe to be installed on the loading and unloading transition structure is hoisted and completely detached from the slider 2 slide block 201, the loading and unloading transition structure returns to an unloaded standby state. At this time, the first drive rod 13 starts to extend again, precisely controlling the lifting guide plate 6 to lift and tilt upwards around the hinge point. The lifting guide plate 6 is adjusted to an inclination angle that matches the conveying requirements of the slag discharge pipe, so that the pushing surface of the lifting guide plate 6 is in close contact with the outer wall of the next slag discharge pipe to be installed stored on the crossbeam 4. Under the combined action of the stable pushing force of the lifting guide plate 6 and the gravity component of the slag discharge pipe itself, the next slag discharge pipe slides smoothly along the horizontal crossbeam 4 until it falls precisely onto the slider 2 slide block 201 of the loading and unloading transition structure, completing another lifting and feeding action, forming a cycle of lifting and feeding, resetting and standby, loading completion, and lifting and feeding again.

[0103] Throughout the process, the first drive rod 13 consistently performs the functions of precisely controlling the angle of the lifting guide plate 6 and driving its reset. The lifting angle and reset position of the lifting guide plate 6 are precisely matched with the conveying requirements of the slag discharge pipe and the loading rhythm of the loading and unloading transition structure, ensuring that each lifting and feeding operation achieves precise docking between the slag discharge pipe and the slider 2, and that each reset provides an interference-free environment for subsequent operations. At the same time, the lifting support 5 always keeps the crossbeam 4 in a horizontal state and does not participate in the reset and lifting actions of the lifting guide plate 6. The clear division of functions avoids interference between the actions of various components, ensuring the stability and accuracy of the slag discharge pipe conveying, and enabling the continuous installation and feeding of multiple slag discharge pipes, improving work efficiency, reducing manual intervention, and preventing the slag discharge pipe from getting stuck, deviating, or being damaged by collision during conveying and loading.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

S203: The slag discharge pipe on the loading and unloading transition structure is lifted by the hoisting mechanism and precisely aligned with the interface of the double-wheel milling air-lift telescopic slag discharge pipe to complete the installation of the slag discharge pipe. At the same time, the slider (2) is controlled to slide and reset, the guide plate (6) is lifted and stored in the opening (8) of the crossbeam (4), and the lifting support (5) is adjusted to the horizontal state of the crossbeam (4) to prepare for the installation of the next slag discharge pipe.

8. The method for disassembling and assembling a dual-wheel milling air-lift telescopic slag discharge pipe according to claim 7, characterized in that, In step 103, after the slag discharge pipe moves to the end of the crossbeam (4) away from the base (1), the second drive rod (14) is driven to make the crossbeam (4) return to horizontal position. When the next slag discharge pipe arrives at the crossbeam (4), the crossbeam (4) is driven to tilt slowly so that the next slag discharge pipe slowly comes into contact with the previous slag discharge pipe.

9. The method for disassembling and assembling a dual-wheel milling air-lift telescopic slag discharge pipe according to claim 7, characterized in that, In step 201, the lifting tilt angle of the lifting guide plate (6) is precisely controlled by the first drive rod (13), and the lifting tilt angle is adapted to the conveying requirements of the slag discharge pipe, so that the lifting guide plate (6) always keeps in close contact with the slag discharge pipe, ensuring that the slag discharge pipe slides smoothly to the loading and unloading transition structure. During this process, the lifting support (5) is only responsible for resetting the crossbeam (4) to a horizontal state and does not participate in the lifting action.

10. The method for disassembling and assembling a dual-wheel milling air-lift telescopic slag discharge pipe according to claim 7, characterized in that, In step 201, after the slag discharge pipe slides smoothly to the loading and unloading transition structure, the first drive rod (13) drives the lifting guide plate (6) to reset to the horizontal position. After the slag discharge pipe to be installed on the loading and unloading transition structure is fully loaded, the lifting guide plate (6) is driven again to lift so that the slag discharge pipe automatically slides into the loading and unloading transition structure.
