Description

Technical Field

[0001] This invention belongs to the field of pipeline hoisting technology, specifically relating to an adaptive clamping and hoisting device for heating pipelines in narrow pipe corridors. Background Technology

[0002] Narrow underground heating pipelines refer to pipeline systems laid in narrow underground spaces in cities to transport heat energy and provide heating and domestic hot water services to buildings. These pipeline corridors have limited space, usually with low clearance and narrow width, which brings many challenges to the installation, maintenance and replacement of pipelines. Heating pipelines in narrow underground corridors are generally arranged in a dense and compact manner to make full use of the limited space. The medium they transport is mostly high-temperature hot water or steam, which places extremely high demands on the insulation, sealing and corrosion resistance of the pipelines. Because the environment of the corridor is closed, once a pipeline leaks or other failures occur, it will not only affect the normal heating supply, but may also damage other facilities in the corridor, or even cause safety accidents. Therefore, there are strict standards and specifications for the quality of the pipelines and the installation process.

[0003] The self-adaptive clamping and hoisting equipment for pipelines is a specialized device for the installation and maintenance of heating pipelines in narrow pipe corridors. It features self-adaptive clamping capabilities, automatically adjusting the clamping force and method according to the specifications, shape, and surface condition of the heating pipeline to ensure that the pipeline does not slip or get damaged during hoisting. This equipment typically consists of a hoisting mechanism, a self-adaptive clamping device, and a control system. In the complex environment of narrow pipe corridors, it can move flexibly and position precisely, efficiently and safely completing the pipeline hoisting task. This greatly improves the efficiency and quality of construction and maintenance of heating pipelines in narrow pipe corridors, while reducing the difficulty and risk of manual operation.

[0004] Because narrow utility tunnels typically contain various pipelines, structural supports, and other facilities, pipe connections involve not only straight pipes but also curved heating pipes. Curved heating pipes can flexibly bypass these obstacles, ensuring smooth laying of the heating pipes and avoiding conflicts with other facilities caused by straight laying. This ensures the normal operation of all facilities within the utility tunnel and the rational use of space. However, existing clamping and hoisting devices are usually designed according to the shape and stress characteristics of straight pipes. The shape and curvature of their clamping surfaces are adapted to straight pipes. Curved heating pipes, on the other hand, are curved and cannot effectively fit with straight pipe clamping structures. This results in a small contact area and uneven distribution of clamping force, making it easy for the pipes to slide or shift during hoisting.

[0005] Therefore, the present invention provides an adaptive clamping and hoisting device for heating pipelines in narrow pipe corridors. Summary of the Invention

[0009] Preferably, each of the two reinforcing components also includes a dual-axis bearing housing, which is fixedly connected to the bottom of the mounting platform. The outer walls of the two shafts of the dual-axis bearing housing are fixedly connected to the inner walls of one end of the two clamping plates. A driving component is provided on the outer side of each clamping plate. The driving component is used to drive the clamping plate to rotate around the shaft of the dual-axis bearing housing as the fulcrum.

[0010] Preferably, each drive assembly includes two clamping rods, the tops of which are fixedly connected to both sides of the mounting platform, and the bottoms of each clamping rod are symmetrically fixedly connected to arc-shaped slides.

Arc-shaped telescopic rods are fixedly connected to the inner walls of both arc-shaped slides, and the output end of the arc-shaped telescopic rods is fixedly connected to one side of the arc-shaped sliders.

[0011] Preferably, a straight telescopic rod is fixedly connected to the bottom of each of the dual-axis bearing seats, and a rubber pad is fixedly connected to the bottom output end of each of the straight telescopic rods. The rubber pad is arc-shaped.

[0012] Preferably, a servo motor is fixedly installed on one side of the inner groove slide, and the output shaft of the servo motor is fixedly connected to a threaded conveying rod. The threaded conveying rod is rotatably connected to the inner wall of the inner groove slide, and an internal threaded slider is threadedly connected to the outer wall of the threaded conveying rod. The internal threaded slider is slidably connected to the inner wall of the inner groove slide and is mutually adapted. A fixed frame plate is fixedly connected to the bottom of the internal threaded slider, and the fixed frame plate is fixedly connected to the outer side of the mounting platform.

[0013] Preferably, a double-axis hinge seat is fixedly installed at the center of the hoisting beam. The outer walls of the two shafts of the double-axis hinge seat are fixedly connected with hinge components. The ends of the two hinge components away from the double-axis hinge seat are respectively fixedly connected to one side of the inner groove slide.

[0014] Preferably, the angle adjustment component includes two arc-shaped telescopic rods II. One end of each arc-shaped telescopic rod II is fixedly connected to the side of the hoisting beam.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses an adaptive clamping and hoisting device for heating pipelines in narrow pipe corridors. The clamping component clamps the outer walls of both ends of the pipeline onto its inclined surface through the relative movement of two clamping blocks, performing initial clamping on the pipeline located on the ground. When clamping a straight pipe, as the clamping blocks approach each other, their inclined surfaces gradually contact the outer wall of the pipeline and generate a squeezing force, so that the clamping blocks can stably, smoothly and tightly fit the outer wall of the pipeline. When clamping a curved pipeline, the clamping component, after angle adjustment, can also accurately correspond to the curved part of the pipeline, achieving effective initial clamping of the curved pipeline.

[0018] 2. The adaptive clamping and hoisting device for heating pipelines in narrow pipe corridors of the present invention, after the pipeline is clamped, the two clamping plates rotate, and one side gradually approaches and adheres to the outer wall of the pipeline. After contact, a certain clamping force is applied. After the clamping component completes the initial clamping, it further clamps and fixes the outer wall of the pipeline, enhances the clamping force on the pipeline, improves the stability of the pipeline during hoisting, and works in conjunction with the clamping component to form a double guarantee.

[0019] 3. The adaptive clamping and hoisting device for heating pipelines in narrow pipe corridors described in this invention, when hoisting curved pipes, adjusts the angle of the inner groove slide by means of an angle adjustment component, thereby driving the two sets of clamping components and reinforcement components to adjust their angles, so that the angle between the two sets of components is consistent with the angle of the curved pipe to be hoisted. This allows the device to accurately correspond to the two parts of the pipe bend. No matter how the degree of pipe bend changes, the device can effectively clamp and reinforce, improving the adaptability and versatility of the device and meeting the hoisting needs of different curved heating pipelines in narrow pipe corridors.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 8As shown, the present invention provides a technical solution: an adaptive clamping and hoisting device for heating pipes in narrow pipe corridors, including a hoisting beam 1, with inner groove slides 4 on both sides of the hoisting beam 1, and lifting rings 7 symmetrically fixedly connected to the upper part of the hoisting beam 1. Clamping components and reinforcing components are provided below the inner groove slides 4. The clamping components include two relatively movable clamping blocks 5, which can clamp the pipe located above the ground when they move closer to each other. The reinforcing components include two rotatable clamping plates 6, which can clamp and fix the outer wall of the pipe by rotation. An angle adjustment component is provided on one side of each of the two inner groove slides 4, which can clamp and fix pipes with different bends by adjusting the angles of the two clamping components and the reinforcing components.

[0025] During operation: Due to the presence of various pipelines, structural supports, and other facilities within narrow utility tunnels, pipe connections involve not only straight pipes but also curved heating pipes. Curved heating pipes can flexibly bypass these obstacles, ensuring smooth laying and avoiding conflicts with other facilities that might occur with straight laying. This guarantees the normal operation of all facilities within the utility tunnel and the rational utilization of space. However, existing clamping and hoisting devices are typically designed with clamping structures tailored to the shape and stress characteristics of straight pipes. The shape and curvature of their clamping surfaces are adapted to straight pipes, while curved heating pipes… The curved shape of the pipe makes it difficult to effectively fit with the straight pipe clamping structure, resulting in a small contact area and uneven clamping force distribution, which can easily cause the pipe to slip or shift during lifting. To solve this problem, in a specific embodiment of this solution, in the initial state, both sets of clamping components and reinforcement components are in a parallel state. When a straight pipe needs to be clamped, the pipe is placed stably on the ground. The entire device is connected to the existing lifting device via lifting ring 7. The existing lifting device precisely controls this device, adjusting it to the appropriate position to ensure that both ends of the pipe are precisely positioned on the two sets of clamping components. At a predetermined position between the clamping blocks 5; subsequently, the two sets of clamping blocks 5 move closer to each other. As the clamping blocks 5 move closer, the inclined surface gradually contacts the outer wall of the pipe and generates a squeezing force, allowing the clamping blocks 5 to more smoothly, steadily, and tightly adhere to the outer wall of the pipe, thus enabling the clamping blocks 5 to clamp the outer walls of both ends of the pipe onto their inclined surfaces; after clamping the pipe, the reinforcement assembly, through the rotation of the two clamping plates 6, causes one side of the two clamping plates 6 to gradually approach and adhere to the outer wall of the pipe, applying a certain clamping force after contacting the outer wall of the pipe, thereby achieving further clamping of the pipe. The device is clamped and fixed, and then the entire device and pipeline are hoisted to the pipe gallery location by a lifting device. When hoisting the curved pipeline, the angle of the inner groove slide 4 is first adjusted by the angle adjustment component, and then the angles of the two sets of clamping components and reinforcement components are adjusted so that the angle between the two sets of clamping components and reinforcement components is consistent with the angle of the curved pipeline to be hoisted. After the angle adjustment is completed, the two sets of clamping components and reinforcement components will accurately correspond to the two parts of the curved pipeline. Then, the two parts of the curved pipeline are clamped and reinforced by the movement of the two sets of clamping blocks 5 and the two sets of clamping plates 6. Through the above embodiments, the clamping assembly clamps the outer walls of both ends of the pipe onto its inclined surface by the relative movement of the two clamping blocks 5, performing initial clamping on the pipe located on the ground. When clamping a straight pipe, as the clamping blocks 5 move closer to each other, their inclined surfaces gradually contact the outer wall of the pipe and generate a squeezing force, allowing the clamping blocks 5 to smoothly, steadily, and tightly adhere to the outer wall of the pipe. When clamping a curved pipe, the clamping assembly, after angle adjustment, can also accurately correspond to the curved part of the pipe, achieving effective initial clamping of the curved pipe. After the pipe clamping is completed, the two clamping plates 6 rotate, and one side gradually moves closer to and adheres to the outer wall of the pipe, applying a certain clamping force after contact, thus completing the initial clamping of the pipe. Subsequently, the outer wall of the pipe is further clamped and fixed to enhance the clamping force and improve the stability of the pipe during hoisting. This works in conjunction with the clamping components to form a double guarantee. When hoisting curved pipes, the angle adjustment component adjusts the angle of the inner groove slide 4, which in turn drives the two sets of clamping and reinforcing components to adjust their angles. This ensures that the angle between the two sets of components matches the angle of the curved pipe to be hoisted, allowing the equipment to accurately correspond to the two curved parts of the pipe. Regardless of the degree of curvature of the pipe, the equipment can effectively clamp and reinforce it, improving its adaptability and versatility, and meeting the hoisting needs of different curved heating pipes in narrow pipe corridors.

[0026] like Figures 5 to 6 As shown, each of the two clamping components also includes a mounting platform 10. A mounting base 8 is fixedly installed above the center of the mounting platform 10. Hydraulic cylinders 9 are fixedly installed on both sides of the mounting base 8. Movable blocks 11 are fixedly connected to the output ends of the hydraulic cylinders 9. The movable blocks 11 can slide and adapt to the inner wall of the mounting platform 10. The top of the movable blocks 11 is fixedly connected to the top of the clamping block 5. Anti-slip pads 12 are provided on the surface of the clamping block 5.

[0027] During operation: When the lifting equipment adjusts the two sets of clamping components to the appropriate positions, the two clamping blocks 5 are located at both ends of the pipe. At this time, the hydraulic cylinders 9 on both sides of the mounting base 8 start synchronously, and their output ends begin to retract, pulling the corresponding movable blocks 11 to slide linearly on the inner wall of the mounting platform 10. As the movable blocks 11 move, the two clamping blocks 5 also move closer to each other. As the clamping blocks 5 gradually approach the pipe, the anti-slip pads 12 on their surfaces come into contact with the outer wall of the pipe. Due to their special material and texture, the anti-slip pads 12 quickly generate a large friction force with the outer wall of the pipe. As the clamping blocks 5 continue to move closer to each other, the squeezing force between the anti-slip pads 12 and the outer wall of the pipe increases continuously, so that the clamping blocks 5 can fit tightly against the outer walls of both ends of the pipe to clamp the pipe, allowing the pipe to be lifted off the ground, preparing for subsequent hoisting operations, and ensuring that the pipe remains stable throughout the hoisting process.

[0028] like Figures 5 to 6 As shown, the two reinforcement components also include a dual-axis bearing seat 13, which is fixedly connected to the bottom of the mounting platform 10. The outer walls of the two shafts of the dual-axis bearing seat 13 are fixedly connected to the inner walls of one end of the two clamping plates 6. A drive assembly is provided on the outer side of each clamping plate 6. The drive assembly is used to drive the clamping plate 6 to rotate around the shaft of the dual-axis bearing seat 13.

[0029] During operation: After the two clamping blocks 5 move closer to each other and complete the clamping of the pipe, the pipe is placed above the clamping blocks 5, with part of its outer wall attached to the inclined surface of the clamping blocks 5. In this state, the pipe is supported by the clamping blocks 5, but has not yet obtained sufficient clamping force to ensure stability during the hoisting process. Just before hoisting, the drive assembly is activated, causing the two clamping plates 6 to rotate around the shaft of the double-axis bearing seat 13. During the rotation, the sides of the two clamping plates 6 gradually approach the outer wall of the pipe. As the rotation continues, they eventually fit tightly against the outer wall of the pipe, thereby applying a stable and uniform clamping force to the pipe. Together with the clamping blocks 5, this provides reliable fixation for the pipe during subsequent hoisting, effectively preventing the pipe from sliding, falling off, or other accidents during hoisting.

[0030] like Figures 5 to 6 As shown, each drive assembly includes two clamping rods 15. The tops of the clamping rods 15 are fixedly connected to both sides of the mounting platform 10. The bottoms of the clamping rods 15 are symmetrically fixedly connected to arc-shaped slide blocks 16. Arc-shaped sliders 14 are slidably connected to the inner walls of the arc-shaped slide blocks 16. One side of the arc-shaped sliders 14 is fixedly connected to the side of the clamping plate 6. Arc-shaped telescopic rods 17 are fixedly connected to the inner walls of the two arc-shaped slide blocks 16. The output end of the arc-shaped telescopic rods 17 is fixedly connected to one side of the arc-shaped sliders 14.

[0031] During operation: When the drive assembly needs to be activated to rotate the clamping plate 6 to clamp the pipe, the two arc-shaped telescopic rods 17 start working simultaneously, driving the arc-shaped slider 14 to slide on the inner wall of the arc-shaped slide block 16. When the arc-shaped slider 14 slides in the arc-shaped slide block 16, it will drive the clamping plate 6 to rotate around the shaft of the double-axis bearing seat 13 as the fulcrum. As the arc-shaped telescopic rods 17 continue to output power, the arc-shaped slider 14 slides continuously. During the rotation, the two clamping plates 6 gradually move closer together and finally fit tightly against the outer wall of the pipe, completing the stable clamping of the pipe.

[0032] like Figures 5 to 6 As shown, a straight telescopic rod 18 is fixedly connected to the bottom of each of the dual-axis bearing seats 13, and a rubber pad 19 is fixedly connected to the bottom output end of each of the straight telescopic rods 18. The rubber pad 19 has an arc shape.

[0033] During operation: After the two clamping plates 6 have clamped and fixed the pipe, the straight telescopic rod 18 is activated. The straight telescopic rod 18 extends downward and drives the rubber pad 19 to move downward. As the rubber pad 19 moves downward, it gradually approaches the top of the pipe and eventually makes the inner side of the rubber pad 19 tightly adhere to the top of the pipe, further enhancing the fixing effect on the pipe. This effectively prevents the pipe from shifting up and down due to shaking, vibration, or other factors during subsequent hoisting. Together with the clamping block 5 and the clamping plates 6, it forms a comprehensive, multi-layered stable clamping system, ensuring the safety and stability of the pipe during hoisting.

[0034] like Figures 3 to 4 As shown, a servo motor 23 is fixedly installed on one side of the inner groove slide 4. The output shaft of the servo motor 23 is fixedly connected to a threaded conveying rod 22. The threaded conveying rod 22 is rotatably connected to the inner wall of the inner groove slide 4. The outer wall of the threaded conveying rod 22 is threadedly connected to an internal threaded slider 20. The internal threaded slider 20 is slidably connected to the inner wall of the inner groove slide 4 and is mutually adapted. The bottom of the internal threaded slider 20 is fixedly connected to a fixing bracket plate 21. The fixing bracket plate 21 is fixedly connected to the outer side of the mounting platform 10 respectively.

[0035] During operation: The distance between the two sets of clamping components and the reinforcing components can be flexibly adjusted by the position of the internal threaded slider 20 in the inner wall of the inner groove slide 4. During adjustment, the servo motor 23 is started, and its output shaft drives the threaded conveying rod 22 to rotate synchronously. When the threaded conveying rod 22 rotates, because the internal threaded slider 20 is threadedly connected to the threaded conveying rod 22, and the internal threaded slider 20 is limited by the inner wall of the inner groove slide 4, it can only slide in a straight line along the inner wall of the inner groove slide 4. As the internal threaded slider 20 slides on the inner wall of the inner groove slide 4, the fixing plate 21 fixedly connected to the bottom of the internal threaded slider 20 also moves accordingly, and the mounting table 10 will follow and be fixed. The support plate 21 moves together, thereby driving the entire clamping assembly and reinforcement assembly to move, realizing precise adjustment of the distance between the two sets of clamping and reinforcement assemblies to adapt to the clamping and reinforcement needs of pipes of different lengths; when facing curved pipes, the angle adjustment assembly flexibly changes the tilt angle of the two inner groove slides 4 according to the actual curvature and direction of the curved pipe, so that the arrangement direction of the two inner groove slides 4 is adapted to the extension direction of both ends of the curved pipe. After the angle adjustment assembly completes the angle adjustment of the two inner groove slides 4, the position adjustment of the inner thread slider 20 can also facilitate the clamping assembly and reinforcement assembly to better clamp curved pipes of different lengths.

[0036] like Figures 7 to 8 As shown, a double-axis hinge seat 2 is fixedly installed at the center of the hoisting beam 1. The outer walls of the two shafts of the double-axis hinge seat 2 are fixedly connected with hinge parts 3. The ends of the two hinge parts 3 away from the double-axis hinge seat 2 are respectively fixedly connected to one side of the inner groove slide 4.

[0037] During operation: When it is necessary to lift the curved pipe, the angle adjustment component will cause the two inner groove slides 4 to rotate with the shaft of the double-axis hinge seat 2 as the fulcrum. As the adjustment is carried out, the two inner groove slides 4 are gradually adjusted to the appropriate angle until their extension direction is perfectly matched with the tangent direction of the curved pipe to be lifted at the corresponding position. At this time, the entire lifting device and the curved pipe form a highly fitted spatial structure, which lays the foundation for the subsequent clamping component and reinforcement component to perform a stable and precise clamping operation on the curved pipe. This ensures the safety and stability of the curved pipe during the lifting process and effectively avoids adverse consequences such as pipe slippage and deformation caused by improper clamping.

[0038] like Figures 7 to 8 As shown, the angle adjustment assembly includes two arc-shaped telescopic rods 24. One end of each arc-shaped telescopic rod 24 is fixedly connected to the side of the hoisting beam 1. The output ends of the arc-shaped telescopic rods 24 are fixedly connected to the side of the inner groove slide 4. An auxiliary slider 25 is fixedly connected to the top of each inner groove slide 4. An auxiliary slide 26 is fixedly installed on the top of the hoisting beam 1. The auxiliary sliders 25 are all slidably connected to the inner wall of the auxiliary slide 26 and are mutually adapted.

[0039] During operation: When it is necessary to adjust the angle between the two inner groove slides 4, the arc-shaped telescopic rod 24 is activated. Driven by the arc-shaped telescopic rod 24, the inner groove slide 4 rotates around the corresponding shaft of the double-axis hinge seat 2. At the same time, the auxiliary slider 25 slides along the inner wall of the auxiliary slide 26. The inner wall of the auxiliary slide 26 and the auxiliary slider 25 are adapted to each other, providing precise guidance and stable support for the sliding of the auxiliary slider 25. This ensures that the movement trajectory of the inner groove slide 4 is accurate during the angle adjustment process, without any deviation or jamming. As the output end of the arc-shaped telescopic rod 24 continues to move, the angle between the two inner groove slides 4 changes continuously until it is adjusted to a suitable angle that matches the bending angle of the curved pipe. At this time, the arc-shaped telescopic rod 24 stops moving and maintains its current state, preparing for subsequent clamping and hoisting operations of the curved pipe.

[0040] like Figures 7 to 8 As shown, a scale 28 is fixedly connected above the hoisting beam 1. Several scale lines are evenly arranged on the surface of the scale 28. A pointer 27 is fixedly connected to the top of the shaft of the double-axis hinge seat 2. The pointer 27 is located above the scale lines.

[0041] During operation: When the inner groove slide 4 rotates to adjust the angle, the shaft of the double-axis hinge seat 2 rotates. The rotation of the shaft directly drives the pointer 27 fixed at its top to rotate. As the angle of the inner groove slide 4 changes, it rotates precisely to the corresponding position. The operator can clearly observe the position of the pointer 27 on the scale 28. Through the scale value corresponding to the pointer 27, the operator can intuitively and accurately understand the current angle adjusted to by the inner groove slide 4. Thus, during the entire angle adjustment process, the scale 28 and the pointer 27 provide the operator with a precise angle reference, making the angle adjustment more accurate and controllable, and ensuring that the hoisting device can better adapt to the hoisting needs of pipes with different degrees of curvature.

[0042] like Figure 7 As shown, a weight mounting column 29 is fixedly connected to the bottom of one side of the hoisting beam 1, and weights can be installed on the outer wall of the weight mounting column 29.

[0043] During operation: When handling curved pipes, the two inner sliding blocks 4 need to be angled according to the shape of the curved pipe. The two lifting rings 7 are usually connected to the lifting equipment by ropes. After the inner sliding blocks 4 are angled, the weight of the clamping components, reinforcing components, and pipe will be concentrated on one side of the lifting beam 1. This concentrated distribution of gravity can easily disrupt the balance of the device. During the lifting process, the imbalance of gravity will cause the entire device to sway and tilt. To effectively deal with this problem, measures can be taken on the outer wall of the weight mounting column 29 fixedly connected to the bottom of the other side of the lifting beam 1. Based on the actual weight generated by the clamping components, reinforcing components, and pipe, a matching weight can be accurately calculated and added. After the weight is installed on the weight mounting column 29, the gravity generated by the weight will form a balancing force with the gravity of the clamping components, reinforcing components, and pipe on the other side. In this way, the device can remain stable during the lifting process, reducing the possibility of swaying and tilting, and ensuring that the curved pipe can be safely and smoothly lifted to the designated position.
