[0027] Hereinafter, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0028] As Figure 1 shown, the pipeline cutting device for boiler installation according to the present application comprises a pipeline clamping mechanism 1, a cutting tool assembly 2, a waste collecting cover 3, a waste guide plate 4 and a sliding support 5.

[0029] The pipe clamping mechanism 1 is used to fix the pipe to be cut. It can adjust the clamping force according to the change of pipe diameter. This mechanism realizes stable clamping of the pipe through a set of adjustable jaws. Each side of the jaw is equipped with a handle, and the operator can change the pressure applied to the outer wall of the pipe by rotating the handle, ensuring that the pipe of any size can be properly constrained in its designated position. In specific application scenarios, such as in large power station construction projects, when used to fix high-temperature and high-pressure steam conveying pipes, steel with moderate hardness is selected to form a rectangular opening structure with rubber bushings as the inner liner to avoid the risk of long-term wear causing damage to the metal surface or leakage. To meet the needs of different types and sizes of pipes, this mechanism is usually designed with multiple specifications, and users can select the appropriate configuration type according to the actual use environment, while allowing for adjustment to cover a range of small-diameter domestic water supply systems to large-diameter industrial production equipment required for various pipe diameters.

[0030] The cutting tool assembly 2 is responsible for implementing the specific cutting process. In order to drive the element to operate normally, it is equipped with a specially designed power transmission link inside, one end of which is connected to the mechanical energy output interface provided by the external motor and other energy devices, and the other side is connected to the small wheel type disc-shaped blade actually used for work. Such design makes the equipment have high power transmission efficiency and can adapt to the requirements of complex field work conditions; it maintains a relatively low inertia torque during rotation to quickly switch states and maintain smooth operation characteristics. In some application scenarios, such as when dealing with large-diameter chimney exhaust cylinder cutting tasks of stainless steel material type, a professional version of tool product made of high-performance alloy steel with wear-resistant coating process and precise grinding teeth may be preferred to complete precise slitting work projects under high quality requirements.

[0031] For the professional auxiliary facilities involved in the waste discharge problem caused by the cutting process, the design of the waste collection cover 3 plays an important role in environmental protection and safety protection. This component is mainly composed of a storage cavity with a certain capacity, and is installed around the cutting tool. In addition, several discharge outlets are reserved for the convenience of subsequent cleaning of accumulated residue. In particular, its shape profile is designed in the form of an inverted cone that is beneficial to the flow characteristics of the material, which can make greater use of gravity to guide the scattered powder to slide down and finally fall into the dust bag or other closed container for centralized treatment, reducing the risk of environmental pollution.

[0032] The waste guide plate 4 is located between the cutting tool assembly 2 and the waste collection cover 3. The plate has a trapezoidal shape and is arranged with a progressive downward inclination. This facilitates the rapid sliding of the freshly cut particles away from the hot cutting blade, reducing the risk of melting and sticking due to excessive friction heat. It also facilitates the introduction of the particles into the pre-prepared collection device for storage and periodic emptying.

[0033] The sliding bracket 5 is the basic frame component that supports and fixes the integrated module unit composed of the above-mentioned main structural components. It can move freely along the parallel straight line direction of the center longitudinal axis of the target to be cut by the bottom sliding rail cooperating with the positioning card slot relative to the main platform base.

[0034] To maximize the capture of fine and fragmented waste particles sprayed from different angles during cutting and reduce the possibility of spreading the influence range to the surrounding space, an additional layer of flexible and resilient folding cover 14 (see Figure 5 ) is attached to the top edge of the waste guide plate 4. When the position of the waste collection cover 3 changes, the folding cover 14 automatically contracts and expands its structure, always maintaining complete wrapping and sealing. Through this innovative design approach, the trajectory direction and propagation distance range of the metal sheet are effectively controlled, thereby protecting the health and life rights of operators and beautifying the cleanliness of the work site environment.

[0035] In summary, to solve the problem of scattered flying debris in traditional cutting processes, the application adopts the design scheme of waste guide plate 4 and folding cover 14 connected thereto. First, the waste guide plate 4 has a suitable inclination angle that can quickly guide the cut material into the waste collection cover 3 instead of randomly scattering. This step significantly reduces the initial state of scattered fragments.

[0036] Secondly, the sliding bracket 5 allows the waste collection system to be adjusted according to the different positions and angles of the pipeline. When the cutting tool cuts into the pipeline, the sliding bracket 5 can advance or retreat synchronously with the movement direction of the cutting tool, always keeping the collection system close to the cutting edge, maximizing the coverage area to ensure that most of the debris can be directly collected into the cover. Specifically, when the cutting tool assembly 2 moves upwards, the side of the sliding bracket 5 close to the cutting tool assembly 2, and when the cutting tool assembly 2 moves downwards, the side of the sliding bracket 5 away from the cutting tool assembly 2, thereby better receiving the flying debris.

[0037] In addition, the addition of the telescopic folding cover 14 provides an additional barrier for the waste collection group. Due to its flexible material, it can be flexibly converted between different positions and forms, not only blocking fine dust flying from the top or side, but also adapting to complex processing paths such as pipe bending.

[0038] In combination with the functions of various components, this design effectively prevents the possibility of a large amount of cutting products suspended and diffused in the air through physical isolation means. It ensures that most of the waste is collected in a specific area for further processing, thus greatly improving the safety and cleanliness of the cutting site.

[0039] In one embodiment, continuing to refer to Figure 1 The sliding support 5 of the pipe cutting device for boiler installation of the present application is symmetrically installed with two groups of guide rails 15 on both sides. The position adjusting assembly 6 composed of a threaded adjusting rod and a positioning block is assembled on the two groups of guide rails 15, which can realize the accurate movement of the waste collection cover 3 in the direction of the pipe axis by adjusting the threaded adjusting rod. This structural design can effectively adapt to pipes of different diameters, ensuring that the debris generated during cutting is always within a controllable range, thereby improving work efficiency and job safety.

[0040] The design of the sliding support 5 ensures that the waste collection cover 3 can be flexibly slid along the pipe axis and adjusted in position if necessary. The threaded adjusting rod realizes micron-level position adjustment accuracy by cooperating with the positioning block. This structure not only provides reliable adjustment function, but also simplifies the operation process of the equipment. The positioning block is used to fix the position of the adjusted threaded adjusting rod, ensuring that there is no displacement phenomenon during cutting.

[0041] For example, when cutting small-diameter pipes, the positioning block is moved to the appropriate position along the guide rail 15 by rotating the threaded adjusting rod, and the waste collection cover 3 is brought close to the cutting point to better capture the cutting chips; for large-diameter pipes, it can be adjusted away from the cutting position according to actual needs to prevent excessive resistance from affecting cutting efficiency. Such a technical implementation makes the cutting device suitable for a wider range of pipe specifications and working scenarios, improving its versatility and flexibility.

[0042] In one embodiment, continuing to refer to Figure 1The flexible folding cover 14 of the pipe cutting device for boiler installation of the present application is externally covered with an anti-static wear-resistant film 7, thereby effectively improving the debris capture effect during the cutting process and further reducing the debris splashing phenomenon. The anti-static wear-resistant film 7 is covered on the outer surface of the flexible folding cover 14 through a special process, having the characteristics of anti-static and wear resistance. The material is selected from high-performance synthetic materials and is strictly tested to ensure service life and functionality, ensuring continuous function during the entire operation process. This design not only increases the friendliness to the operating site environment, but also ensures that the device can still efficiently prevent debris from spreading everywhere and keep the work area clean after long-term operation.

[0043] In addition, to ensure the specific technical implementation of this feature, the flexible folding cover 14 is connected with the waste collection cover 3 and automatically adjusts the position with the movement of the sliding support 5 to adapt to the cutting process in different positions. In order to ensure the effective expansion and contraction action of the flexible folding cover 14, a support structure is specially provided in the design to maintain the flexible folding cover 14 always closely around the pipe cutting area, whether in the initial position or when the sliding frame moves along the pipe axis, it can be closely fitted without gaps. For example, the skeleton structure of the flexible folding cover 14 is made of high-elasticity material to ensure that it can quickly recover to its original shape when it expands or contracts, and the additional coating does not affect its flexibility. At the same time, this layer of coating is closely combined with the skeleton, which does not interfere with the folding function while enhancing the wear resistance. Specifically, the anti-static wear-resistant film 7 is directly bonded to the surface of the flexible folding cover 14 during manufacturing, ensuring stability during long-term use and durability in high-temperature environments during cutting work.

[0044] In one embodiment, the waste guide plate 4 of the pipe cutting device for boiler installation of the present application adopts a modular splicing structure. The interface between each module is designed with a good butt joint surface to ensure that it can be quickly assembled and disassembled in actual operation, thereby facilitating cleaning and maintenance. A buffer sealing pad 9 is embedded between the modules. The buffer sealing pad 9 not only compensates for the dimensional tolerance at the module connection, but also effectively prevents small cutting debris from leaking from the gap between the modules, ensuring the cleanliness of the working environment.

[0045] The buffer sealing pad 9 is made of flexible wear-resistant material and has certain elasticity and anti-aging performance. When the modules are tightly combined, the sealing pad can still maintain its original shape after being slightly compressed, and at the same time, it can well fill the contact area, so that the device can maintain its sealing property even in long-term use. This modular design also makes it possible to restore the overall function by replacing the damaged module if a single unit is damaged or excessively worn.

[0046] In addition, the installation position of each module is located on the sliding bracket 5, and the modular splicing structure ensures the integrity of the waste guide plate 4. Specifically, each independent module unit can be connected to each other through simple buckles, latches and the like, and the disassembly and reassembly process can be completed without using tools. By optimizing the geometric shape design of the interface and applying the buffer gasket 9, the sealing performance of the device can be significantly improved, further preventing the escape of debris.

[0047] In one embodiment, the telescopic folding cover 14 of the pipe cutting device for boiler installation of the present application realizes the sliding and magnetic attraction fixing function with the waste guide plate 4. In order to ensure that the debris generated during the cutting process can be effectively captured and reduce splashing, in the device, the two sets of telescopic folding covers 14 symmetrically arranged above the waste guide plate 4 become one of the key components. When the telescopic folding cover 14 adjusts the position, the free end can smoothly slide in the special sliding groove opened on the surface of the waste guide plate 4, and the self-adaptive adjustment according to the actual working condition requirement is realized. The fixing is completed through the magnetic attraction connecting piece between the two, and the stability of the telescopic folding cover 14 after adjustment is ensured.

[0048] Specifically, the material of the telescopic folding cover 14 needs to consider its deformability and moderate magnetic attraction force. For example, flexible magnetic strips or metal sheets are inlaid or attached to the free end edge of the telescopic folding cover 14 as the magnetic attraction assembly, and correspondingly, a material with appropriate magnetism is arranged inside or on the surface of the waste guide plate 4 to match. When the operator moves the telescopic folding cover 14 to the required position according to the actual situation, the free end of the telescopic folding cover 14 is tightly fixed at the corresponding sliding groove position by relying on this pre-configured magnetic attraction relationship. In this way, it not only does not affect the requirement for position flexibility in the normal work process, but also fully ensures the necessity of the relative fixation between the components.

[0049] In one embodiment, as shown in Figure 2 The cutting tool assembly 2 of the pipe cutting device for boiler installation of the present application is lifted by the electric push rod 11 to realize the overall cutting of the pipe. Specifically, the electric push rod 11 is fixed on the support structure and connected with the cutting tool assembly 2. By adjusting the telescopic stroke of the electric push rod 11, the vertical movement range of the cutting tool assembly 2 can be controlled, and then it can be ensured that it can accurately feed up and down on the surface of the pipe. This design not only enables the equipment to perform stable cutting tasks on pipes with different diameters and wall thicknesses, but also enhances the ability of the machine to adapt to complex workpieces.

[0050] Specifically, the cutting tool assembly 2 is closely coupled with the lower end of the electric push rod 11, ensuring synchronous action of the two. Through the external controller sending signals to the electric push rod 11, the ascending or descending distance of the electric push rod 11 is accurately controlled, thereby driving the cutting tool assembly to adaptively approach or move away from the cutting position. In this process, the entire cutting device remains relatively stable, effectively ensuring that the cutting quality is not affected by external factors.

[0051] For example, the maximum stroke range of the electric push rod 11 can be limited by installing a stroke switch to prevent equipment failure caused by excessive compression. In addition, using a servo motor as a power source in combination with a closed-loop control system to monitor the state of each movement enables each cutting operation to be accurately completed within the set parameter range. This structural configuration can ensure safe and reliable cutting process, while having high repeatability and being suitable for processing needs of various specifications of pipes.

[0052] In one embodiment, as shown in Figure 3 The waste collection cover 3 of the pipe cutting device for boiler installation of the present application is provided with a negative pressure aspirator 12 at the bottom end. The negative pressure aspirator 12 is connected to a flow guide pipe 10 for discharging the collected fine dust and other waste. In order to improve the overall work efficiency and ensure the cleanliness of the internal environment, the device integrates a filter screen 8 structure inside the waste collection cover 3, which can form an inward airflow under the action of negative pressure. This airflow can effectively suck the fine particulate matter and waste gas generated during the cutting process into the internal collection device, thereby reducing its pollution to the surrounding environment. Through reasonable internal space layout, large particles of debris entering the device are blocked when they encounter the filter screen 8, avoiding potential damage to more precise key parts such as the negative pressure aspirator 12.

[0053] In one embodiment, the filter screen 8 can be first placed in the inner cavity of the waste collection cover 3 below the top and at a certain inclination angle, so that the substances generated during the cutting process can naturally slide to a specific area without completely blocking the mesh; at the same time, the negative pressure aspirator 12 is installed at the lowest part of the entire collection system, ensuring that any residual or not completely filtered fine particles can be smoothly sucked and treated; in addition, the flow guide pipe 10 connected to the opposite side is directly connected to the waste treatment area outside the system. In addition, the selection of the connection position ensures that all components are in close contact without gaps to improve work efficiency and ensure smooth and safe operation of the device without leakage.

[0054] In one embodiment, as shown in Figure 4As shown, a spring damper 13 is provided between the waste collection cover 3 and the sliding support 5 of the pipe cutting device for boiler installation of the present application, which is used to effectively absorb the vibration generated during the operation of the device. The design ensures that the waste collection cover 3 can always adhere to the surface of the pipe and work stably. The specific position of the spring damper 13 is located on the support point of the sliding support 5 and the contact surface of the waste collection cover 3, so that it can form a buffer structure between the two. This configuration enables the waste collection cover 3 to adapt to changes in pipe shape and diameter, avoiding the impact on work efficiency caused by vibration or displacement.

[0055] The spring damper 13 is composed of high-strength spring elements, the two ends of which are connected with the sliding support 5 and the waste collection cover 3 respectively. Specifically, the spring is locked at one end of the sliding support 5 by a fixed clamp, and the other end is connected to the internal structure of the waste collection cover 3 by a similar method. Through the above components and assembly mode, the shaking caused by power transmission from the transmission mechanism can be effectively offset. For example, when the cutting tool operates at high speed and generates strong vibration, the spring installed between the two components can deform accordingly, thereby releasing the force transmitted to the waste collection cover 3, ensuring the smooth and continuous operation of the device.

[0056] In one embodiment, the manual screw rod of the pipe cutting device for boiler installation of the present application is provided as an electric adjustment system 16, which is equipped with a remote control panel. By replacing the traditional manual screw rod with the electric adjustment system 16, convenient, fast and smooth movement of the sliding support 5 during pipe cutting is achieved. Specifically, this improvement enables the operator to easily adjust the position of the sliding support 5 through the remote control panel, thereby ensuring that the waste collection cover 3 connected to the sliding support 5 always remains in the optimal working position, so as to better collect the debris and waste generated during the cutting process.

[0057] The installation position of the electric adjustment system 16 is at the original position of the manual screw rod, and its core structure includes a motor drive module and a lead screw assembly. The remote control panel is placed in a safe area away from the cutting site, which is convenient for operators to monitor and control. The motor drive module is responsible for converting electrical signals into mechanical motion, driving the lead screw to rotate along the axis, and then accurately adjusting the position of the sliding support 5. Stable connection structure is adopted between the electric adjustment system 16 and the sliding support 5, which ensures consistent support and positioning function in the entire working range.

[0058] For example, the electric adjustment system 16 can be designed to use an alternating current brushless motor or a stepping motor as the power source, and a reduction gearbox is configured to increase the torque output; at the same time, an encoder is built in to feedback the actual displacement of the sliding bracket 5, to ensure that the action accuracy meets the requirements. In addition, in order to achieve smooth movement, a guide rail 15 or a pulley auxiliary component can be installed on the electric adjustment system 16 to reduce friction and improve the smoothness of sliding. The remote control panel is integrated with an LCD display screen and several function keys, so that the user can easily perform various operations.

[0059] In actual operation, when the device is in use, first place the pipe to be cut in the pipe clamping mechanism 1, adjust the pipe clamping mechanism 1 so that the pipe is firmly fixed, and ensure that the clamping force is suitable for the diameter of the pipe. Then start the power source, and the power drives the cutting tool assembly 2 through the transmission mechanism to perform cutting work. At the same time, the waste guide plate 4 can effectively guide the debris generated during cutting to slide into the waste collection cover 3 due to the inclined arrangement, ensuring that the debris is orderly collected. In addition, the telescopic folding cover 14 automatically adjusts its length according to the position of the waste collection cover 3, covering the cutting area to reduce the possibility of debris flying during cutting and improve the collection efficiency of the debris. During this process, the entire device moves along the pipe axis direction through the sliding bracket 5, ensuring that the entire pipe is continuously and uniformly cut. In this way, after cutting is completed, the debris in the waste collection cover 3 can be uniformly cleaned, keeping the working environment clean.

[0060] The above is the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can make several improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
