Description

Technical Field

[0001] This invention belongs to the field of pipeline transportation technology, and particularly relates to a pipeline guiding and transportation device for municipal construction. Background Technology

[0002] In municipal construction, pipeline laying is a fundamental and crucial step. Traditional pipeline transportation methods often rely on manual handling and mechanical hoisting, which are inefficient and prone to damaging the pipelines. Therefore, corresponding pipeline transportation devices or pipeline handling devices have emerged. Existing pipeline transportation devices often use conveyor chains or platform structures for transportation. However, such structures have drawbacks, such as the inability to center the pipeline and the tendency for it to tip over during transportation. This makes it impossible to control the spacing between pipelines, which seriously affects the construction efficiency and project quality of pipeline laying.

[0003] Patent publication number 111268354B disclosed an oil pipeline transportation device, including a support mechanism, a clamping and conveying mechanism, a spacing adjustment mechanism, a bending connecting rod, a first auxiliary support mechanism, a transmission mechanism, and a second auxiliary support mechanism. The top of the support mechanism is fixedly connected to the spacing adjustment mechanism; the spacing adjustment mechanism is drivenly connected to two clamping and conveying mechanisms; the two clamping and conveying mechanisms are symmetrically slidably fitted at both ends of the support mechanism; the upper ends of one bending connecting rod are fixedly connected to the two ends of each of the two clamping and conveying mechanisms, and the lower ends of four bending connecting rods are fixedly connected to one of the first auxiliary support mechanisms. Multiple of these inventions can be installed in opposite directions to form a transportation line, continuously transporting the pipeline horizontally, reducing labor, and improving the stability and speed of transportation.

[0004] Existing technologies utilize multiple sets of evenly spaced clamping and conveying mechanisms in conjunction with a spacing adjustment mechanism to achieve uniform pressure clamping on the outer surface of the pipeline, enabling the pipeline to be centered and transported stably, thereby effectively improving pipeline docking accuracy and construction efficiency. However, certain shortcomings still exist in overall application: First, existing clamping and conveying mechanisms still rely mainly on manual operation to clamp and convey pipelines, resulting in a low overall level of automation. This makes it difficult to achieve continuous and efficient pipeline conveying operations, leading to a need to improve construction efficiency. Furthermore, the adjustment of multiple clamping points is also done manually, which is cumbersome and cannot ensure uniform clamping force at each clamping point. This can easily lead to uneven force on the pipeline surface and affect the docking accuracy.

[0005] Secondly, during the production and storage of pipelines, dust, oil and other impurities can easily accumulate on their surface. If these impurities are not effectively cleaned before pipeline laying, they may be pressed into the pipeline surface or adhere to the joint end during transportation, affecting welding quality and sealing performance. Existing technology can only transport and clamp pipelines, and it is difficult to achieve the above-mentioned cleaning function, thus failing to meet the requirements for surface cleanliness before pipeline laying.

[0006] Finally, most existing technologies are fixed structures, making it difficult to adjust the height or direction of the pipeline. They cannot meet the flexible adjustment requirements in complex construction scenarios, and the devices have many limitations in use. Furthermore, existing technologies cannot guarantee the stability of the pipeline's posture during docking, which can easily lead to offset or shaking, affecting the final welding quality and construction accuracy. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention provides a pipeline guiding and conveying device for municipal construction. This invention solves problems such as low automation, insufficient overall flexibility, poor stability during pipeline connection, and inability to clean the pipeline surface in existing technologies. It effectively improves the automation level of pipeline conveying, meets the flexible adjustment needs of different construction scenarios, ensures the stability of the pipeline during connection, and can simultaneously complete the cleaning of the pipeline surface, ensuring the construction quality of subsequent pipeline laying.

Composite belts are slidably disposed on both sides of the two inclined seats. A steel wire layer is embedded within the composite belt. A reinforcing layer is filled between the steel wire layer and the composite belt. The upper part of the composite belt is arc-shaped and fits against the pipeline. When the pipeline is connected, the composite belt moves downward to form a clamping relationship with the abutment rollers and can adjust the position of the pipeline.

[0011] Preferably, a connector is fixedly installed on the upper surface of both connecting plates. The bottom of the connector located at the inlet of the conveyor chain pipe is connected to a water supply pipe, and the bottom of the connector located at the outlet of the conveyor chain pipe is connected to an air supply device. The two connectors spray high-pressure water mist and high-pressure airflow onto the pipe, respectively.

[0012] Preferably, a slot can be opened in the middle of each of the composite strips, and a connecting pipe is embedded in the slot. Both ends of the connecting pipe extend downward along the composite strip. The part of the connecting pipe inside the slot has multiple connecting holes, and water flow or air flow can pass through the multiple connecting pipes respectively.

[0013] Preferably, the conveyor chain includes multiple interconnected V-shaped base plates, each of which is hinged to the other via a hinge joint. Conveying rollers are rotatably mounted on both sides of the first and second conveyor frames. The outer circumference of each conveying roller is provided with toothed grooves that cooperate with the multiple V-shaped base plates. The meshing of the toothed grooves with the V-shaped base plates enables power transmission. Each V-shaped base plate is provided with a V-groove structure on its outer end face.

[0014] Preferably, a reinforcing plate is fixedly provided on the V-shaped surface of the V-shaped base plate. The outer surface of the reinforcing plate is roughened. Buffer blocks are sleeved on both sides of the V-shaped surface of the reinforcing plate. The buffer blocks are made of wear-resistant rubber material. A roughened pad is provided on the outer surface of the buffer blocks. The buffer blocks are positioned in contact with the pipe.

[0015] Preferably, the first conveyor frame and the second conveyor frame are respectively provided with tension adjustment mechanisms. The tension adjustment mechanism includes two sliding tables on the first conveyor frame or the second conveyor frame. A lifting frame is slidably arranged between the two sliding tables. Both ends of the lifting frame are provided with notches for the conveyor chain to pass through. A pressure roller is rotatably arranged inside the lifting frame.

The pressure roller abuts against the outer surface of the reinforcing plate when the conveyor chain is conveying.

[0016] Preferably, brush rollers are provided on both sides of the pressure roller inside the lifting frame. During the rotation of the pressure roller, the brush rollers contact the reinforcing plate and the rough surface pad to form a cleaning process.

[0017] Preferably, a plurality of lifting rings are arranged on the top end face of the support frame, and lifting hooks can be threaded through the lifting rings.

[0018] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) The present invention, through the arrangement of the conveyor chain, linear drive module and connecting block and other structures, enables the device to automatically adjust the contact position and clamping force between the conveyor chain and the pipe surface according to the actual outer diameter of the pipe, thereby realizing adaptive clamping and conveying of pipes of different specifications. With the addition of crawling trolley and composite belt and other structures, the device can also automatically adjust the height and installation angle of the pipe according to the installation position and installation height, which significantly improves the versatility and construction adaptability of the device. (2) The present invention can not only realize the automated continuous conveying of pipelines by the conveying chain composed of reinforcing plates and buffer blocks, but also play a certain role in shock absorption during the conveying process, so that the pipeline remains stable during the conveying process. On this basis, the connecting plate that can automatically rotate the angle, together with the composite belt that pulls down and the abutment roller, can also slightly adjust the posture and angle of the pipeline when the pipeline is docked, thereby ensuring the flatness and fit of the docking end face, and further improving the pipeline docking quality and sealing performance.

[0019] (3) By setting up structures such as composite belt and connecting pipe, as well as connecting device and jet box, the present invention enables the pipe to not only make slight adjustments to its posture during the docking process, but also to clean the pipe surface during the transportation process, effectively removing impurities such as dust and oil, and drying excess water in the pipe to avoid moisture residue affecting the welding quality. This invention achieves integrated cleaning and drying of the pipe, effectively improving the surface quality of the pipe before docking.

[0020] (4) By setting up structures such as lifting frame, pressure roller and brush roller, the present invention can not only effectively tension the conveyor chain during pipeline conveying to ensure transmission stability, but also remove dust from the surface of the conveyor chain, so that impurities attached to the surface of the conveyor chain after long-term use can be effectively removed, thus effectively extending the service life of the conveyor chain.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1: Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 3A pipeline guiding and conveying device for municipal construction includes a rectangular bracket 12 welded from multiple steel structural components. A first conveying frame 14 is fixedly installed on the upper part of the rectangular bracket 12. A second conveying frame 15 is slidably installed above the first conveying frame 14. The second conveying frame 15 and the first conveying frame 14 have the same basic structure, both being welded from steel structural components. Both ends of the second conveying frame 15 are rotatably connected to conveying rollers 24 via bearing seats. A conveying chain 16 is driven between the two conveying rollers 24. The transverse cross section of the conveying chain 16 is V-shaped, thus forming a V-shaped conveying channel between the upper and lower conveying chains 16. A pipeline 23 is clamped and conveyed within this V-shaped conveying channel. When the two conveying chains 16 rotate simultaneously in one direction, the pipeline 23 can be moved to one side. Therefore, a first drive unit 22 is fixedly installed on one side wall of both the second conveying frame 15 and the first conveying frame 14. The first drive unit 22 is a high-torque servo motor, which is fixedly connected to one end of the conveying roller 24 via a coupling, thereby providing power for the rotation of the conveying chain 16. The second conveyor frame 15 differs from the first conveyor frame 14 in that at least four sets of first push cylinders 13 are provided between the second conveyor frame 15 and the rectangular bracket 12. Each first push cylinder 13 is a hydraulic cylinder. Through the extension and retraction of the first push cylinder 13, the second conveyor frame 15 is driven to slide horizontally above the first conveyor frame 14, thereby adjusting the distance between the upper and lower conveyor chains 16. On the one hand, it can adapt to different pipe diameters 23, and on the other hand, it facilitates the insertion and removal of pipes 23. Furthermore, different clamping forces are applied when the pipes 23 are conveyed to ensure that the pipes 23 do not deviate or slip during the conveying process.

[0024] Specifically, when the pipe 23 needs to be pushed into each pre-fixed bracket, the worker can place the rectangular bracket 12 on a platform of the corresponding height, aligning the axis of the pipe 23 with the axis of the bracket. Then, the worker can insert one end of the pipe 23 into the V-shaped conveying channel between the upper and lower conveyor chains 16. Next, the first push cylinder 13 is activated, and its output end drives the second conveyor frame 15 downwards, causing the upper and lower conveyor chains 16 to clamp the pipe 23. Then, the two first drive units 22 are activated, each driving the conveyor roller 24 to rotate via a coupling, which in turn drives the conveyor chains 16 to rotate, thus allowing the pipe 23 to move smoothly forward within the V-shaped conveying channel until the pipe 23 is completely inside the bracket. It should be noted that this application is only for pipe conveying; how the pipe is fixed to the bracket and the parameters of the corresponding bracket are well-known technical content to those skilled in the art and will not be elaborated here. In addition, to improve the stability of the conveying process, the two first drive units 22 and the multiple first push cylinders 13 can be synchronously linked and controlled by the same control system, thereby ensuring that the pipeline 23 is subjected to uniform force during the conveying process.

[0025] Further, see attached document. Figure 1 and attached Figure 6 The specific conveyor chain 16 includes multiple interconnected V-shaped base plates 40. Each V-shaped base plate 40 is hinged to each other by a hinge joint 44. The hinge joint 44 is divided into two groups, namely an upper row of hinge points and a lower row of hinge points. The upper row of hinge points and the lower row of hinge points are arranged alternately and respectively set at the two ends of adjacent V-shaped base plates 40, so that two adjacent V-shaped base plates 40 can rotate relative to each other. This allows the conveyor chain 16 to rotate around the outside of the conveyor roller 24. It should be noted that the outer circumference of the conveyor roller 24 is also provided with toothed grooves that cooperate with the multiple V-shaped base plates 40. Power transmission is achieved through the meshing of the toothed grooves with the V-shaped base plates 40. Each V-shaped base plate 40 has a V-shaped groove structure on its outer end face. The V-shaped grooves on multiple V-shaped base plates 40 together form a V-shaped conveying channel for accommodating the pipe 23. The V-shaped groove structure has a certain centering function, which can automatically guide the pipe 23 to the center position of the V-shaped groove and form multi-point contact on the outer circle surface of the pipe 23 during clamping and conveying, further improving the stability of conveying.

[0026] Furthermore, see the attached document. Figure 1 and attached Figure 6 A reinforcing plate 43 is fixedly installed on the V-shaped surface of the V-shaped base plate 40. Both the reinforcing plate 43 and the V-shaped base plate 40 are made of metal and have the same V-shaped outer surface. The outer surface of the reinforcing plate 43 is roughened. Buffer blocks 41 are fitted on both sides of the V-shaped surface of the reinforcing plate 43, covering the entire V-shaped surface of the reinforcing plate 43. The buffer blocks 41 are positioned precisely at the contact point with the pipe 23. The buffer blocks 41 are made of wear-resistant rubber material and have a certain elastic cushioning capacity. A roughened pad 42 is provided on the outer surface of the buffer block 41. The outer surface of the roughened pad 42 is roughened to increase the friction between it and the pipe 23 and prevent slippage. Specifically, the V-shaped base plate 40 is a basic limiting structure, while the reinforcing plate 43 is a detachable wear-resistant liner, fixed to the V-shaped surface of the V-shaped base plate 40 with bolts, facilitating individual replacement after wear without replacing the entire V-shaped base plate 40. Both the buffer block 41 and the roughened pad 42 are arranged outside the reinforcing plate 43. When the pipe 23 is clamped and conveyed, the roughened pad 42 replaces the reinforcing plate 43 in contact with the pipe 23, thereby protecting the reinforcing plate 43 from wear. At the same time, the elastic deformation capacity of the buffer block 41 absorbs the impact and vibration during the conveying process, further improving the smoothness of the conveying. In this process, the reinforcing plate 43 provides a reliable support foundation for the buffer block 41 and the roughened pad 42, ensuring that the buffer block 41 and the roughened pad 42 will not deform excessively under pressure, thereby maintaining the stable geometry of the V-shaped conveying channel.

[0027] Further, see attached document. Figure 1 Appendix Figure 4 and attached Figure 7To facilitate the mobile use of the device, this application also includes a crawling trolley 10, which is a mobile base. The crawling trolley 10 comprises a detection module 18 and a crawling module 34 mounted on one side of its end face. The detection module 18 includes a vision probe and a lighting unit, enabling real-time visual detection and positioning of the ground. The crawling module 34 includes crawling wheels, crawling tracks, and a drive motor, allowing the crawling trolley 10 to move autonomously on the ground. The detection module 18 is used to collect real-time ground environmental information. A control module 35 is located inside the crawling trolley 10 on one side of the detection module 18. The control module 35 controls the movement of the crawling module 34 and the visual acquisition by the detection module 18, enabling autonomous navigation and obstacle avoidance. The control module 35 integrates control circuitry and a wireless communication module, enabling the crawler trolley 10 to move flexibly in pipes or complex ground environments via remote control or preset path planning. To ensure the device's travel distance, a power supply module 33 is also provided at the bottom of the crawler trolley 10. The power supply module 33 includes a battery pack and a power management system, providing a continuous and stable power supply to the crawler module 34 and the detection module 18, ensuring long-term continuous operation of the device. It should be noted that the trolley structure represented by the crawler trolley 10 largely adopts mature designs from existing technologies. The descriptions in this application are only for the convenience of detailing the parts related to the innovation of this application. Other unmentioned structures and functions can be implemented with reference to existing technologies and will not be elaborated here.

[0028] Furthermore, see the attached document. Figure 1 Appendix Figure 3 and attached Figure 7The rectangular bracket 12 and the first conveyor frame 14 can all be mounted on the crawler trolley 10 and moved, thereby enabling continuous operation on different pipe sections. To ensure that the axis of the pipe 23 can be smoothly aligned with the axis of the mounting bracket during the positioning of the pipe 23 before conveying, this application also arranges a lifting assembly above the crawler trolley 10, which can lift the rectangular bracket 12 and the first conveyor frame 14 and move them up and down. Specifically, the lifting assembly includes support plates 11 on both sides of the upper end face of the crawler trolley 10. Two slide rails 58 are provided on the adjacent end faces of the two support plates 11. The two slide rails 58 are arranged vertically and connected to connecting blocks 59 on their outer surfaces. A linear drive module 36 is fixedly installed on the end face of the support plate 11 between the two slide rails 58. The sliding end of the linear drive module 36 is fixedly connected to the connecting block 59. A support frame 21 is fixedly connected to the outer end face of the rectangular bracket 12. The support frame 21 and the connecting block 59 are detachably connected by bolts and fasteners. The linear drive module 36 drives the connecting block 59 to slide up and down along the slide rails 58, thereby causing the support frame 21 and the rectangular bracket 12 to move up and down as a whole, so as to align the axis of the pipe 23 with the mounting bracket. This application enables the conveying device to adapt to different heights through the cooperation of the crawler trolley 10 and the lifting component, which significantly improves the adaptability and work efficiency of the device. In addition, the entire conveying device can also directly serve as a pipeline transport trolley, directly carrying the pipeline to the appropriate position and then pushing the pipeline, thereby greatly reducing the difficulty and time cost of manual handling and docking.

[0029] Reference Appendix Figure 1 and attached Figure 7 It should be noted that the linear drive module 36 uses a servo motor as the drive source and achieves the lifting and lowering of the sliding end through a lead screw and nut pair. This linear drive module has a compact structure, high control precision, and can achieve millimeter-level lifting and lowering adjustments. Furthermore, this application also includes a channel steel 25 fixedly connected between the two support plates 11 and the upper surface of the crawler trolley 10. The channel steel 25 reinforces the support plates 11 on both sides, ensuring the overall stability of the support plates 11. Simultaneously, the channel steel 25 protrudes from the upper surface of the crawler trolley 10. When the lifting assembly is not in use, the lifting assembly can lower the rectangular bracket 12 as a whole, allowing the bottom of the rectangular bracket 12 to contact the channel steel 25. This provides overall support for the rectangular bracket 12, reducing the load on the linear drive module 36 when the lifting assembly is idle and extending its service life.

[0030] Further, see attached document. Figure 7To ensure the stability of the crawler trolley 10 during pipeline transportation, this application provides multiple support units 57 at the bottom of the crawler trolley 10. Each support unit 57 includes a hydraulic cylinder and a pressure plate. The pressure plate is pushed against the ground by the output end of the hydraulic cylinder, thereby fixing the crawler trolley 10 in the working position and preventing the device from shifting or shaking during pipeline transportation.

[0031] Furthermore, see the attached document. Figure 5 Appendix Figure 8 and attached Figure 9 To ensure the tension of the conveyor chain 16 during transport in the pipeline 23, this application provides tension adjustment mechanisms on the frames of the first conveyor frame 14 and the second conveyor frame 15, respectively. Each mechanism includes two sliding platforms 28 mounted on either the first or second conveyor frame 14. The two sliding platforms 28 are located on opposite sides of the conveyor chain 16. One sliding platform 28 has a fixed sliding rod inside, while the other sliding platform 28 has a rotatably mounted threaded rod 39 inside. One end of the threaded rod 39 extends beyond the outer end face of the sliding platform 28, and a handle is provided on the end face of the threaded rod 39 extending beyond the outer end face of the sliding platform 28. A slider is driven by the threaded rod 39 within the sliding platform 28, and another slider slides on the sliding rod within the other sliding platform 28. A lifting frame 27 is fixedly mounted between the two sliders. Notches for the conveyor chain 16 to pass through are provided on both ends of the lifting frame 27. A pressure roller 32 is rotatably mounted inside the lifting frame 27 within these notches. The outer surface of the pressure roller 32 is roughened, and its cross-section is V-shaped.

[0032] Specifically, during the pipeline transport process of the conveyor chain 16, another part of the conveyor chain 16 passes through the notch on the lifting frame 27 and enters the interior of the lifting frame 27. The outer surface of the reinforcing plate 43 inside the conveyor chain 16 comes into contact with the outer surface of the pressure roller 32. At this time, the operator can rotate the handle to drive the threaded rod 39 to rotate, thereby driving the slider to move along the sliding table 28, causing the lifting frame 27 to move the pressure roller 32 closer to the conveyor chain 16. This allows the pressure roller 32 to press the conveyor chain 16 inward, increasing the overall tension of the conveyor chain 16 and ensuring sufficient friction between the conveyor chain 16 and the pipeline 23, preventing the pipeline 23 from slipping or shifting during transport. During the transmission process of the conveyor chain 16, because the outer surfaces of the pressure roller 32 and the reinforcing plate 43 are in contact and both are roughened, the friction between them is large. This ensures that the pressure roller 32 and the reinforcing plate 43 maintain a stable contact state while the pressure roller 32 is rotated by the conveyor chain 16, thus continuously providing reliable tension.

[0033] Furthermore, see the attached document. Figure 5 Appendix Figure 9 and attached Figure 10During the stacking process before installation, some dust will adhere to the surface of the pipe 23. This dust will indirectly adhere to the surface of the reinforcing plate 43 and the rough pad 42 during the transportation process, thus affecting the transportation accuracy and service life. To this end, brush rollers 55 are arranged on both sides of the pressure roller 32. During the process of the pressure roller 32 tensioning the conveyor chain 16 and being driven to rotate by the conveyor chain 16, the pressure roller 32 will also drive the brush rollers 55 on both sides to rotate. When the brush rollers 55 rotate, their bristles will contact the surfaces such as the reinforcing plate 43 and the rough surface pad 42, thereby removing dust from these structural surfaces and maintaining the cleanliness of the conveying system. In addition, in order to avoid a large amount of dust accumulating inside the lifting frame 27, two connecting pipes 54 are provided on the bottom and side wall end faces of the lifting frame 27, respectively. It should be noted that in actual operation, an air pump and a vacuum cleaner need to be placed on the outside of the device, such as the end face of the crawler trolley 10. The air outlet of the air pump is connected to the connecting pipe 54 on the side wall of the lifting frame 27 through a hose, and the suction end of the vacuum cleaner is connected to the connecting pipe 54 at the bottom of the lifting frame 27 through a hose. Under the action of the air pump, the airflow is quickly injected into the interior of the lifting frame 27 from the connecting pipe 54 on the side wall of the lifting frame 27, forming a positive pressure airflow. This helps to blow dust away from the surface of the reinforcing plate 43 and the rough pad 42, and can also remove dust from structures such as the brush roller 55 and the pressure roller 32. At this time, the vacuum cleaner sucks in the blown-away dust and airflow together through the connecting pipe 54 at the bottom, forming a negative pressure suction, which effectively prevents dust from being deposited again inside the lifting frame 27 and ensures a continuous and stable dust removal effect.

[0034] Example 2: A pipeline guiding and conveying device for municipal construction, further optimized based on Embodiment 1, is described in the attached document. Figure 4 Appendix Figure 10 and attached Figure 11In municipal construction scenarios, due to the long length of the required pipeline system, multiple pipeline segments often need to be connected sequentially. That is, after one pipeline segment enters the mounting bracket, another segment needs to be joined with the previous segment before continuing transport. To ensure stability during joining, this embodiment adds a corresponding structure, specifically including support platforms 17 located at both ends of a rectangular bracket 12. A support plate 29 is positioned above the support platform 17, and a connecting plate 31 is fixedly mounted on the top surface of the support plate 29. Two inclined seats 45 are respectively positioned on both sides of the top surface of the connecting plate 31, with adjacent surfaces of the two inclined seats 45 arranged as inclined surfaces. An abutment roller 46 is rotatably mounted on the inclined surface of the inclined seat 45. It should be noted that during the outward transport of the pipeline, the outer surface of the pipeline 23 will contact the outer surface of the abutment roller 46. With the continuous transport of the pipeline 23, the abutment roller 46 will rotate accordingly, thereby assisting in a smooth transition of the pipeline and reducing frictional resistance during joining. Meanwhile, the abutment roller 46 is made of high-damping rubber material, which can effectively buffer the vibration during pipeline transportation and ensure the coaxiality and stability of the pipeline docking process.

[0035] Furthermore, see the attached document. Figure 10 and attached Figure 11 On both sides of the inclined seat 45, there are two symmetrically arranged rectangular notches on the end face of the connecting plate 31. Each pair of opposite rectangular notches forms a group. A composite belt 20 is slidably arranged in each group of rectangular notches. The end of the composite belt 20 above the notch is bent into an arc shape. The ends of the two composite belts 20 below the notch are fixedly connected to each other. A second push cylinder 49 is fixedly arranged on the bottom end face of the connecting plate 31 between the two composite belts 20. The output end of the second push cylinder 49 extends downward and is fixedly connected to the connection area between the two composite belts 20. The second push cylinder 49 is an electric push cylinder that can detect the lifting pressure of the output end. When the output end of the second push cylinder 49 extends downward, its lifting pressure will be fed back to the control system in real time, thereby realizing precise control of the clamping force.

[0036] Specifically, when the pipe 23 has completed most of its conveying and is ready for pipe docking under the drive of the upper and lower conveyor chains 16, the output end of the second pusher cylinder 49 extends downward, thereby pushing the two composite belts 20 downward. The inner surface of the downward-moving composite belts 20 gradually contacts the outer surface of the pipe 23. During this continuous contact, the two composite belts 20 press the pipe 23 downward, limiting the pipe 23 between the abutment roller 46 and the composite belts 20, thus stabilizing the pipe and facilitating subsequent docking operations. Furthermore, after pipe docking is completed, the output end of the second pusher cylinder 49 retracts upward, driving the composite belts 20 upward, causing the inner surface of the composite belts 20 to disengage from the outer surface of the pipe 23, releasing the limitation on the pipe 23, and allowing the pipe to continue forward conveying. This structure, in addition to providing temporary limitation during pipe docking, also allows the composite belts 20 to provide secondary clamping of both ends of the pipe when the entire device moves with the pipe, thereby ensuring stability.

[0037] Furthermore, see the attached document. Figure 12 To ensure the limiting strength of the composite belt 20, the composite belt 20 in this application is made entirely of high-damping rubber material, with anti-slip textures on its inner surface to increase the friction with the outer surface of the pipe. To ensure the strength of the composite belt 20 when limiting the pipe 23, multiple steel wire layers 52 are embedded inside the composite belt 20. These steel wire layers 52 are made of elastic metal material, allowing them to undergo appropriate elastic deformation under pressure, ensuring reliable clamping of the pipe while preventing damage to the pipe surface due to rigid contact. A reinforcing layer 53 is wrapped around the outside of the steel wire layers 52, and the composite belt 20 is wrapped around the reinforcing layer 53. The reinforcing layer 53 fills the gap between the steel wire layers 52 and the reinforcing layer 53. The reinforcing layer 53 is preferably made of cloth material to facilitate stress transfer between the steel wire layers 52 and the composite belt 20, thereby improving the overall durability of the device while ensuring clamping strength. It should be noted that the end of the steel wire layer 52 above the connecting plate 31 is pre-bent into an arc shape before use. This allows the arc-shaped end to more smoothly conform to the outer surface of the pipe 23 when the composite belt 20 moves downwards, and also prevents interference between the pipe and the flexible composite belt 20 during outward transport. Furthermore, to ensure smooth movement of the composite belt 20, the connection between the two composite belts 20 is made of metal, and the output end of the second push cylinder 49 is fixedly connected to this metal section, thus ensuring the synchronicity and stability of the two composite belts 20 during movement.

[0038] Furthermore, see the attached document. Figure 10 Appendix Figure 11 and attached Figure 12A rotating disk 19 is rotatably mounted on the end face of the support platform 17. The upper end face of the rotating disk 19 is fixedly connected to one bottom end of the support plate 29. A second drive unit 50 is fixedly mounted on the bottom end face of the support platform 17, and the output end of the second drive unit 50 is fixedly connected to one bottom end of the rotating disk 19. Although this application uses a V-shaped cross-section conveyor chain 16 for conveying pipelines, in actual use, although the V-shaped cross-section of the conveyor chain 16 can provide initial guidance for the pipeline, it cannot provide precise angle adjustment during docking. Therefore, if a certain angular deviation occurs at the pipe interface during the pipe docking process, after the composite belt 20 has completed its positioning of the pipe, the second drive unit 50 can be used to drive the rotating disk 19 to rotate, thereby rotating the support plate 29 and the connecting plate 31. Since the composite belt 20 and the abutment roller 46 have already positioned both ends of the pipe, the support plate 29, driven by the second drive unit 50, drives the rotating disk 19 to rotate, causing the support plate 29 and the connecting plate 31 to undergo an overall angular deflection. This allows for fine-tuning of the pipe ends, ensuring precise alignment of the pipe interface and guaranteeing smooth subsequent docking operations. It should be noted that the angular deviation during pipe docking cannot be predicted. To save costs, this application does not include an angle detection structure. During actual docking, operators can visually observe the docking of the pipe interface and manually control the drive amount of the second drive unit 50 to achieve real-time correction of the pipe docking angle, ensuring that the docking accuracy meets process requirements.

[0039] It should be noted that during pipe angle adjustment, the two conveyor chains 16 can be loosened to allow the pipe to move relatively freely. This prevents excessive frictional resistance between the pipe, the composite belt 20, and the abutment roller 46 during the angle adjustment process, thus avoiding damage to the pipe surface or jamming of the adjustment operation due to excessive friction. After the angle adjustment is completed, the conveyor chains 16 re-clamp the pipe to ensure its stability during the docking process.

[0040] Example 3: A pipeline guiding and conveying device for municipal construction, further optimized based on Embodiment 1 or 2, is described in the attached document. Figure 4 Appendix Figure 10 and attached Figure 11During the installation and transportation of pipe 23, the clay and dust adhering to its surface can severely affect the transportation efficiency and docking accuracy, thereby affecting the quality of pipe connection. Therefore, in this embodiment, a connector 30 is fixedly installed on the upper end face of the connecting plate 31 on the pipe entry side of the conveyor chain 16. The upper end face of the connector 30 has multiple small holes. In actual operation, a water supply pipe is connected to the bottom end face of the connector 30, and high-pressure water is sprayed onto the pipe surface through the connector 30 to wash away the clay and dust adhering to the pipe surface. Simultaneously, a slot 51 is opened in the middle of the composite belt 20 above the connecting plate 31, and a connecting pipe 47 is embedded in the slot 51. Both ends of the connecting pipe 47 extend downwards along the composite belt 20. In actual operation, both ends of the connecting pipe 47 are connected to the water supply pipe. Multiple connecting holes 48 are opened in the portion of the connecting pipe 47 within the slot 51, with the spray direction of the connecting holes 48 facing the pipe surface. In actual operation, the high-pressure water flow acts on the pipe surface simultaneously through the connector 30 and the connecting pipe 47, forming a two-way flushing from top to bottom. This effectively removes clay, dust and other impurities from the outer surface of the pipe, ensuring the pipe surface is clean and thus improving the sealing and reliability during subsequent connection. Furthermore, during the flushing process, the composite belt 20 can also move downwards appropriately and contact the outer surface of the pipe. The elastic deformation of the composite belt 20 is used to scrape the pipe surface, assisting in the removal of residual impurities and further improving the cleaning effect.

[0041] It should be noted that the aforementioned communicating vessel 30 and communicating pipe 47 are both arranged on the side between the pipe and the two conveyor chains 16, so that the surface dust and dirt can be washed off before the pipe is conveyed by the two conveyor chains 16.

[0042] Furthermore, see the attached document. Figure 5 Two jet boxes 37 are fixedly installed on the inner two side walls of the support frame 21. Multiple jet holes 38 are provided on the adjacent end faces of the two jet boxes 37, with the jet holes 38 pointing towards the pipe surface. In actual operation, an air pump is connected to the outside of the jet boxes 37 for air supply. During the process of the pipe being transported between the two conveyor chains 16, the air pump connected to the jet boxes 37 generates a high-pressure airflow, which is sprayed onto the pipe surface through the jet holes 38. This blows away residual moisture and impurities on the pipe surface, further ensuring the dryness and cleanliness of the pipe surface and creating good surface conditions for subsequent sealing and connection.

[0043] It should be noted that, where conditions permit, heating elements can be arranged inside the jet box 37 to heat the gas entering the jet box 37, thereby forming a hot airflow that is sprayed onto the pipe surface. This not only removes moisture and impurities but also dries the pipe surface, further improving its dryness and creating more favorable conditions for subsequent sealing and connection.

[0044] In addition, it should be noted that the appendix Figure 2 and attached Figure 4 Above each of the two connecting plates 31, there are connecting devices 30 and connecting pipes 47. The purpose is that if the pipe is flushed and scraped off before entering the conveyor chain 16, but the two air jet boxes 37 do not effectively remove moisture or leave residual impurities, an air supply pipe and air supply equipment can be connected to the connecting devices 30 and connecting pipes 47 on the other side of the conveyor chain 16. The high-pressure gas sprayed from the connecting pipes 47 and connecting devices 30 at close range can then be used to blow away the residual moisture and impurities on the pipe surface, further enhancing the drying effect. For this purpose, the connecting devices 30 and connecting pipes 47 are preferably detachable, and two sets are provided. One set is used for spraying water, in which case the connecting device 30 is a sprayer, and the other set is used for spraying air, in which case the connecting device 30 is a nozzle. This allows for flexible switching between flushing and drying functions according to actual working conditions, further improving the adaptability and cleaning effect of the device.

[0045] Example 4: A pipeline guiding and conveying device for municipal construction, further optimized based on Embodiment 1 or 3, is described in the attached document. Figure 1 In addition to being used with a crawler trolley 10, this device can also be used for lifting with hoisting equipment. This application has multiple lifting rings 26 arranged on the top end face of the support frame 21. The lifting hook can pass through the holes on the lifting rings 26 to lift the rectangular bracket 12 and the support frame 21 and other conveying structures, thereby lifting the pipeline to the designated position for pipeline transportation.

[0046] Finally, it should be noted that although this device can be moved by mounting the crawler trolley 10 or a hoisting structure during actual use, the entire device remains relatively fixed during pipeline transportation. Therefore, the air pump, water supply pipe, corresponding water supply structure, and vacuum cleaner used in the above embodiments can be placed on the ground for use during pipeline transportation, or the end face of the crawler trolley 10 can be widened to mount these devices on it for easy movement and to ensure the stable operation of each functional module of the device. Furthermore, a small control cabinet will be provided outside the device for centralized control of the start / stop and parameter adjustment of the air pump, water supply pipe, vacuum cleaner, and other equipment, as well as the coordinated action of each functional module, achieving integrated automatic control of pipeline transportation, cleaning, drying, and docking. The specific control logic and methods of the device can be programmed and implemented by those skilled in the art according to actual needs, and will not be elaborated here. Specific control structures such as PLCs, sensors, and solenoid valves can also be selected and used by those skilled in the art according to actual needs, and will not be elaborated here.

This specification and claims do not distinguish components based on differences in name, but rather on differences in function.
