Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a traction device for sewage pipeline construction. Background Technology

[0002] In the process of modern urbanization, the construction of municipal infrastructure, especially sewage pipe networks, has become a crucial part of urban development. With the expansion of urban scale and population growth, sewage volume is increasing year by year, placing higher demands on the design, construction, and operation of sewage pipe networks. Currently, sewage pipe network construction faces numerous technical challenges, mainly in key processes such as pipe pulling, positioning, and cutting.

[0003] Currently, the main construction method for sewage pipeline laying is to use excavators to dig trenches and then manually lay the pipes. This method has significant technical drawbacks: First, the commonly used double-wall corrugated pipes are long and heavy, making manual handling and positioning extremely difficult, resulting in high labor intensity and low construction efficiency. Second, existing traction equipment has limited functionality, only enabling pipe movement and failing to effectively limit pipe movement during traction, easily leading to pipe displacement or detachment. Third, pipe cutting still requires a separate process, increasing construction steps and wasting manpower and resources. Particularly noteworthy is the lack of integrated construction equipment in current technology; the separation of traction and cutting processes leads to low construction efficiency. The lack of stable support and positioning during pipe cutting not only affects cutting quality but also poses safety hazards. Furthermore, the debris generated during cutting is difficult to collect, polluting the construction environment and increasing subsequent cleanup workload.

[0004] Therefore, it is necessary to improve the existing sewage pipeline construction equipment so that it can effectively solve the above-mentioned defects. Utility Model Content

[0023] This application proposes a traction device for sewage pipe network construction, including a base 1 with a moving function and a conveying device disposed on top of the base 1 for moving a sewage pipe. The base 1 is provided with a limiting mechanism for limiting the movement of the sewage pipe, and a cutting mechanism for cutting the sewage pipe is provided at the limiting mechanism. The base 1 can adopt a tracked or wheeled moving structure. The tracked base 1 is suitable for muddy or uneven construction sites, while the wheeled base 1 is more suitable for flat and hard ground. The conveying device can adopt a belt conveyor, chain conveyor, or roller conveyor, among which the belt conveyor has the advantages of smooth operation and low noise. The limiting mechanism can be implemented by a guide wheel set, a clamping device, or a limiting baffle. For example, a V-shaped guide wheel set can be used to adapt to sewage pipes of different diameters. The cutting mechanism can adopt a disc saw, a band saw, or a laser cutting device, among which the disc saw is suitable for cutting large-diameter pipes, and the band saw is more suitable for cutting thick-walled pipes. This technical solution integrates movement, traction, limiting, and cutting functions, solving the problem of limited functionality in existing equipment. The mobile base 1 enables rapid equipment relocation, the conveying device automates pipeline traction, the limiting mechanism ensures pipeline stability during traction and cutting, and the cutting mechanism precisely severs the pipeline. Therefore, this equipment reduces manual intervention during construction, improves work efficiency, and prevents pipeline displacement or detachment during cutting. Compared with existing technologies, this solution effectively solves the challenges of traction, limiting, and cutting in pipeline construction through functional integration, achieving continuity and safety in the construction process.

[0024] In this embodiment, the limiting mechanism includes a first support plate 3, a second support plate 4, and a third support plate 5 arranged sequentially from front to back along the sewage pipe conveying direction. The first support plate 3 is located at the inlet end of the conveying direction, the second support plate 4 and the third support plate 5 are located at the inlet end of the conveying direction, and the cutting mechanism is located between the second support plate 4 and the third support plate 5. Limiting holes 6 are provided on the first support plate 3, the second support plate 4, and the third support plate 5. The first support plate 3, the second support plate 4, and the third support plate 5 are arranged sequentially along the sewage pipe conveying direction to form continuous limiting support for the sewage pipe. The limiting holes 6 are used to accommodate the sewage pipe, keeping it stable during conveying. The first support plate 3 is located at the inlet end and is used for initial guidance and positioning of the sewage pipe; the cutting mechanism is located between the second support plate 4 and the third support plate 5 to facilitate cutting operations while limiting the flow. As a preferred embodiment, the limiting holes 6 can be designed with an adjustable diameter to accommodate sewage pipes of different diameters. Furthermore, the support plates can be made of high-strength steel to improve durability and stability.

[0025] Therefore, this technical solution, by setting up multiple support plates and limiting holes 6, achieves continuous limiting and stable transportation of the sewage pipe, solving the problem of sewage pipes easily falling off during traction in existing technologies. Simultaneously, placing the cutting mechanism between the second support plate 4 and the third support plate 5 facilitates cutting operations under the limiting state, improving construction efficiency and safety. Compared with existing technologies, this solution has a simple structure, is easy to operate, and can effectively ensure stable transportation and precise cutting of the sewage pipe.

[0026] In this embodiment, a slide rail mechanism is also included, which is mounted on the third support plate 5 and used to drive the cutting mechanism to reciprocate vertically. The slide rail mechanism includes an electromagnetic slide rail 8 fixedly mounted on the side of the third support plate 5 facing the second support plate 4, and an electromagnetic slider 9 mounted on the electromagnetic slide rail 8. A connecting vertical plate 11 for mounting the cutting mechanism is fixed on the electromagnetic slider 9. The electromagnetic slide rail 8 uses the principle of a linear motor, generating driving force through electromagnetic induction to make the electromagnetic slider 9 move smoothly along the slide rail. This is existing technology and will not be described in detail here. The electromagnetic slider 9 and the connecting vertical plate 11 are fixedly connected by bolts for easy disassembly and maintenance. As a preferred embodiment, a dustproof sealing strip can be provided on the surface of the electromagnetic slide rail 8 to prevent cutting debris from entering the slide rail. The connecting vertical plate 11 is made of high-strength aluminum alloy, reducing the overall weight while ensuring structural strength. The stroke of the electromagnetic slide rail 8 can be adjusted according to actual needs to adapt to the cutting requirements of sewage pipes of different diameters. Thus, this technical solution, through the cooperation of the electromagnetic slide rail 8 and the electromagnetic slider 9, achieves precise positioning and stable movement of the cutting mechanism in the vertical direction. Among them, the electromagnetic drive method has the characteristics of fast response speed and high control precision, which can effectively avoid the gap error problem of traditional mechanical transmission. Furthermore, the connecting vertical plate 11 serves as an intermediate connecting component, ensuring the installation stability of the cutting mechanism and providing sufficient operating space for the movement of subsequent cutting components.

[0027] In this embodiment, the cutting mechanism includes a connecting vertical plate 11 fixedly mounted on the electromagnetic slider 9. The connecting vertical plate 11 has a protrusion 12 on the side facing the third support plate 5, which connects to the electromagnetic slider 9. The protrusion 12 increases the installation space between the second support plate 4 and the third support plate 5. The connecting vertical plate 11 also has a horizontal groove 13 on the side facing the second support plate 4. The connecting vertical plate 11 is fixed to the electromagnetic slider 9 by bolts or welding, ensuring a stable connection between the cutting mechanism and the slide rail mechanism. The protrusion 12 has a trapezoidal or semi-circular structure, increasing the distance between the connecting vertical plate 11 and the third support plate 5, providing more space for the installation and operation of the cutting mechanism. The horizontal groove 13 is a T-groove or dovetail groove structure, used to guide the reciprocating motion of the movable rod 15. Ball bearings or a lubricating coating can be provided inside the horizontal groove 13 to reduce the frictional resistance of the movable rod 15 during movement.

[0028] This technical solution, through the cooperative design of the connecting vertical plate 11 and the protrusion 12, effectively solves the installation and operation problems of the cutting mechanism in a narrow space, ensuring the installation and control of the motor in the cutting mechanism. The protrusion 12 not only increases the operating space but also enhances the structural strength of the connecting vertical plate 11. The horizontal slide 13 allows for precise guidance of the movable rod 15, ensuring the stability of the cutting process.

[0029] In this embodiment, the cutting mechanism further includes a movable rod 15 disposed on the side of the connecting vertical plate 11 facing the second support plate 4 and capable of being driven to reciprocate along the length of the horizontal slide groove 13. The movable rod 15 has a slide bar 16 on the side facing the connecting vertical plate 11 for sliding engagement with the horizontal slide groove 13. Through the sliding engagement structure between the movable rod 15 and the horizontal slide groove 13, precise positioning and stable movement of the cutting mechanism are achieved. The engagement design of the slide bar 16 and the slide groove 13 effectively prevents deflection during movement, ensuring the straightness of the cutting trajectory. Compared with the manual hand-held cutting method in the prior art, this mechanical guiding structure significantly improves cutting accuracy and operational safety. Simultaneously, the modular design of the movable rod 15 facilitates the replacement of suitable cutting components according to different pipe diameter requirements, improving the equipment's versatility. While ensuring cutting accuracy, this structure effectively reduces vibration and noise during movement by optimizing the engagement clearance of the sliding pair.

[0030] In this embodiment, a vertical rod 17 is fixed to the bottom of the movable rod 15, and a saw blade 18 for cutting sewage pipes is fixed to the bottom of the vertical rod 17. Through the linkage structure of the movable rod 15, the vertical rod 17, and the saw blade 18, mechanized cutting of the sewage pipe is achieved. When the movable rod 15 reciprocates within the horizontal groove 13, it drives the vertical rod 17 and the saw blade 18 to move synchronously, and the saw teeth of the saw blade 18 continuously cut the pipe material during the movement. This design solves the problems of low efficiency and safety hazards associated with manual cutting, while avoiding the shortcomings of traditional traction equipment that cannot complete the cutting operation synchronously. Compared with solutions that require a separate cutting station, this integrated cutting mechanism can complete pipe cutting in real time during traction, significantly improving construction efficiency and ensuring cutting accuracy.

[0031] In this embodiment, a drive assembly for driving the movable rod 15 is also included. The drive assembly includes a cutting motor 19 fixed to the side of the connecting vertical plate 11 facing the third support plate 5. The output end of the cutting motor 19 passes through the connecting vertical plate 11 and is fixed to a disc 20. A connecting rod 21 is rotatably connected to the outside of the disc 20, and one end of the connecting rod 21 is rotatably connected to the movable rod 15. This drive assembly achieves automatic reciprocating motion of the movable rod 15 through the mechanical transmission of the motor driving the disc 20 and the connecting rod 21, replacing the traditional manual operation method. Due to the mechanical transmission structure, the movement trajectory and speed of the movable rod 15 remain stable, ensuring the cutting accuracy of the saw blade 18 on the sewage pipe. At the same time, the motor-driven method significantly improves cutting efficiency compared to manual operation, and the operator does not need to directly contact the cutting part, improving construction safety.

[0032] In this embodiment, a battery is enclosed at the bottom of the base 1, providing power to the cutting mechanism, conveying device, and slide rail mechanism. The battery is encapsulated in a waterproof housing at the bottom of the base 1, secured with bolts, and sealed with a sealing strip at the joint to prevent sewage ingress. The battery's output is connected to each electrical device via a waterproof connector. The power supply line for the cutting mechanism is arranged along the slide rail mechanism, while the power supply line for the conveying device is arranged through internal grooves in the base 1. The battery is equipped with an overload protection circuit that automatically cuts off power when the current exceeds a set threshold. The battery can also be configured with a fast-charging interface to support temporary power replenishment at the construction site. This technical solution integrates the battery at the bottom of the base 1, achieving overall power supply for the traction equipment and avoiding the movement limitations and safety hazards associated with external power cables. The enclosed installation design effectively prevents sewage and debris from corroding the battery, improving the equipment's reliability in harsh environments. With unified power supply, the cutting mechanism, conveying device, and slide rail mechanism can work collaboratively, ensuring the continuity of the sewage pipe traction and cutting process. Compared to equipment requiring external power, this solution significantly improves construction efficiency and reduces operational interruptions caused by power wiring.

[0033] In this embodiment, the conveying device is a belt conveyor 2. The belt conveyor 2 includes a driving wheel, a driven wheel, and a belt wrapped around the driving wheel and driven wheel. The driving wheel is driven to rotate by a motor, thereby driving the belt. The belt surface can be provided with anti-slip textures to increase friction with the sewage pipe. The belt conveyor 2 can be equipped with a speed regulating device to control the conveying speed by adjusting the motor speed. The speed regulating device can be implemented using a frequency converter or a mechanical speed change mechanism. Therefore, the belt conveyor 2 can smoothly and continuously convey the sewage pipe, avoiding slippage or jamming during traction. The working principle of the belt conveyor 2 is that the motor drives the driving wheel to rotate, driving the belt to circulate, thereby moving the sewage pipe placed on the belt along the conveying direction. The anti-slip texture design effectively prevents relative slippage of the sewage pipe during conveying. The speed regulating device allows the conveying speed to be adjusted according to actual construction needs, ensuring conveying efficiency while avoiding pipe deviation or detachment due to excessive speed. Compared with existing technologies that rely solely on manual labor or simple mechanical traction, the use of belt conveyor 2 can achieve automated conveying, significantly improve construction efficiency, and reduce the intensity of manual labor.

[0034] In this embodiment, a collection box 22 is provided between the second support plate 4 and the third support plate 5. The collection box 22 is elongated and used to collect cutting debris. The collection box 22 can be made of metal or plastic and can be fixed between the second support plate 4 and the third support plate 5 by buckles or bolts. By setting a dedicated collection container at a key position of the limiting mechanism, the problem of on-site pollution caused by debris scattering during the cutting process is effectively solved. The specific working principle is as follows: when the cutting mechanism cuts the sewage pipe, the generated debris falls directly into the elongated collection box 22 below, avoiding the situation of debris scattering everywhere in traditional construction. This design maintains the compactness of the equipment structure and realizes automatic collection of debris, reducing the frequency of manual cleaning and improving the cleanliness of the construction environment.

[0035] Working principle: The device is placed in the excavated trench for pre-embedded corrugated pipes. The bottom of the device is equipped with pulleys for easy movement. The corrugated pipe is then passed sequentially through the limiting holes 6 of the first support plate 3, the second support plate 4, and the third support plate 5, with the bottom of the corrugated pipe resting on the belt conveyor 2. The belt conveyor 2 is then started to move the corrugated pipe forward within the trench, achieving traction. The limiting holes 6 help prevent the corrugated pipe from falling off the traction device. During construction, the corrugated pipe sometimes needs to be cut according to the site conditions. When cutting is required, the cutting motor 19 is started, causing the electromagnetic slider 9 to slide downwards on the electromagnetic rail 8, thus moving the connecting vertical plate 11 downwards. Simultaneously, the cutting motor... 19 drives the disc 20 to rotate. The rotation of the disc 20 drives the movable rod 15 to slide back and forth quickly through the connecting rod 21. At this time, the slide bar 16 moves in the slide groove 13, providing support for the reciprocating sliding of the movable rod 15. When the movable rod 15 slides back and forth, it drives the saw blade 18 to slide back and forth quickly through the vertical rod 17. While the saw blade 18 slides back and forth, it also has a downward force. When it descends, the saw blade 18 contacts the corrugated pipe, and then the corrugated pipe is cut by the high-speed reciprocating sliding of the saw blade 18. Thus, the corrugated pipe is automatically cut during traction, avoiding the time and effort of manual cutting. The waste chips that fall off during cutting fall into the collection box 22 and are collected uniformly. Then, the collection box 22 can be cleaned periodically.
