Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline construction technology, and in particular to a tool for rapid connection and installation of water conservancy pipelines. Background Technology

[0002] Rapid connection and installation tools for water conservancy pipelines play a crucial role in water conservancy engineering construction, with a wide range of applications covering multiple fields such as water resource allocation, irrigation, and drainage. For water conservancy pipelines with flanges, rapid and reliable pipe connection and installation tools can significantly improve construction progress, reduce construction costs, and ensure the stability and safety of the pipeline system.

[0003] Existing water pipeline connection technologies still have some shortcomings. Taking patent document CN222783104U, entitled "An Auxiliary Device for Water Pipeline Connection," as an example, this patent proposes a solution that uses the retraction of an electric telescopic rod to bring two pipeline flanges closer together for connection. It utilizes the bolt holes on the flanges to pull the two flanges together, and the extension and retraction of the electric telescopic rod, in conjunction with a flexible rigid rod and connecting studs, achieves rapid connection of the flanges. However, this solution has a significant drawback: the flexible rigid rod and the electric telescopic rod are inflexible, constituting a rigid structure. When the flanges of the two pipelines are significantly misaligned, precise alignment of the two flanges cannot be achieved, leading to alignment failure and reduced construction efficiency.

[0004] In summary, the shortcomings of existing hydraulic pipeline docking auxiliary devices severely affect the efficiency and flexibility of hydraulic pipeline laying. Developing a rapid docking installation tool for hydraulic pipelines that can flexibly guide the relative positioning of flanges has become an urgent need in the current hydraulic engineering construction field. Utility Model Content

[0005] The present invention aims to provide a tool for quick connection and installation of water conservancy pipelines to overcome the shortcomings mentioned above.

[0006] In order to achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A tool for rapid connection and installation of water conservancy pipelines includes:

[0008] A movable block and a fixed block, positioned opposite each other, are used to engage with the bolt holes of two flanges on opposite sides. A conical block is detachably connected to the movable block near the fixed block. A conical concave surface is provided on the fixed block near the conical block. The conical block selectively slides with the conical concave surface.

[0009] A connecting rope and a traction assembly are provided. The middle part of the connecting rope passes through the fixed block and the conical block. The two ends of the connecting rope are respectively connected to the movable block and the traction assembly. The traction assembly is used to drive and pull the connecting rope and drive the movable block and the fixed block to move closer to each other.

[0010] Furthermore, the traction component is connected to or integrally formed with the fixed block, and the tips of the conical block and the conical concave surface are positioned away from the movable block.

[0011] Furthermore, one end of the connecting rope passes through the conical block and the movable block in sequence, and is fixedly connected to the first limiting ring after passing through the positioning ring. The positioning ring can be switched between a first position and a second position. In the first position, the positioning ring abuts against the first limiting ring and the end of the movable block away from the fixed block, respectively. In the second position, the positioning ring moves along the direction of the connecting rope and passes through the movable block.

[0012] Furthermore, along the length direction of the connecting rope, the projection of the first limiting ring is located inside the projection of the positioning ring;

[0013] The positioning ring has multiple protrusions integrally formed on its edge. The end face of the movable block away from the fixed block is provided with an embedding groove. In the first position, the protrusions are embedded in the embedding groove. In the second position, the protrusions move through the movable block along the direction of the connecting rope.

[0014] Furthermore, the movable block is stepped, comprising an integrally formed first stop, a first sleeve, and a first connecting part arranged sequentially. The first stop and the first sleeve are both cylindrical structures. The first stop abuts against the opposite side of one of the flanges. The embedding groove is provided on the end face of the first stop. The first sleeve passes through the bolt hole. The first connecting part is detachably connected to the conical block.

[0015] Furthermore, the first connecting part is a threaded post, and the end face of the tapered block away from the fixed block is provided with an internal thread, and the threaded post is detachably connected to the internal thread.

[0016] Furthermore, the fixing block is also stepped, including an integrally formed second stop and a second sleeve. Both the second stop and the second sleeve are cylindrical structures. The second stop abuts against the opposite side of the other flange. The second sleeve passes through the bolt hole and is provided with a conical concave surface that matches the conical block.

[0017] Furthermore, the traction assembly includes two connecting rods that are crossed and rotatably connected in the middle. One end of one of the connecting rods is integrally formed with the second stop portion. The other end of the connecting rope passes through one end of the other connecting rod and is fixedly connected to a second limiting ring. The second limiting ring abuts against the other end of the other connecting rod. The other ends of one connecting rod and the other end of the other connecting rod are respectively fixedly connected to the two ends of a power telescopic rod.

[0018] Furthermore, the power telescopic rod is an electric push rod, which is electrically connected to a control module, and the control module is electrically connected to a power source.

[0019] Compared with the prior art, this utility model has at least the following advantages:

[0020] (1) This utility model features a movable block and a fixed block arranged opposite each other. A conical block is detachably connected to the side of the movable block closest to the fixed block, and a conical concave surface is provided on the side of the fixed block closest to the conical block. When the two bolt holes are significantly misaligned, a traction component drives a connecting rope to move. The connecting rope rubs against the conical concave surface, causing the flange at the movable block position to move and gradually shorten the misalignment of the two bolt holes. Subsequently, when the conical block penetrates the conical concave surface, the friction between the conical block and the concave surface corrects the position of the two threaded holes again, ultimately achieving precise alignment of the threaded holes. This utility model, through the guidance of the connecting rope and the conical concave surface, and the conical block and the conical concave surface, achieves the alignment and connection of the bolt holes of the two flanges, enabling rapid alignment and improving construction efficiency.

[0021] (2) Both the movable block and the fixed block have a stepped structure, including a first stop, a first socket, and a first connecting part, all integrally formed and arranged sequentially, as well as a second stop and a second socket. This structural design allows the movable block and the fixed block to be stably engaged in the bolt holes of the flange, and achieves rapid mating between the flange holes through the cooperation of the tapered block and the tapered concave surface. This design not only improves the flexibility of flange mating but also adapts to flanges of different diameters and spacings, thus expanding the applicability of the tool.

[0022] (3) When the positioning ring is in the first position, it can fix one end of the connecting rope to the movable block; when the positioning ring is in the second position, it can pull the positioning ring and the first limiting ring out of the movable block, thereby releasing the connection between one end of the connecting rope and the movable block. This design makes the disassembly and assembly of the tool simpler and faster, improves the reusability of the tool, and further improves the construction efficiency.

[0023] In summary, this utility model, through its innovative structural design and operation method, effectively solves the problems of difficult and inefficient connection of water conservancy pipelines in the prior art, improves the efficiency and quality of water conservancy pipeline laying, and has significant practical value and broad application prospects.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-3 This utility model provides a quick connection and installation tool for water conservancy pipelines, including a movable block 1, a conical block 3, a fixed block 2, a connecting rope 4, and a traction component 5.

[0032] The movable block 1 and the fixed block 2 are arranged opposite each other, and are used to engage with the bolt holes of the two flanges on opposite sides. A conical block 3 is detachably connected to the side of the movable block 1 near the fixed block 2, and a conical concave surface 23 is provided on the side of the fixed block 2 near the conical block 3. The conical block 3 can selectively slide with the conical concave surface 23. A connecting rope 4 passes through the middle of the fixed block 2 and the conical block 3, and its two ends are connected to the movable block 1 and the traction assembly 5, respectively. The traction assembly 5 is used to drive the connecting rope 4 and move the movable block 1 and the fixed block 2 closer together.

[0033] In use, when the two bolt holes are significantly misaligned, the traction component 5 drives the connecting rope 4 to move. The connecting rope 4 rubs against the conical concave surface 23, causing the flange at the position of the movable block 1 to move and gradually shorten the misalignment of the two bolt holes. Subsequently, when the conical block 3 enters the conical concave surface 23, the friction between the conical block 3 and the conical concave surface 23 corrects the position of the two threaded holes again, ultimately achieving precise alignment of the threaded holes.

[0034] This invention achieves the alignment and connection of the bolt holes of the two flanges by connecting the rope 4 and the conical concave surface 23, and guiding the conical block 3 and the conical concave surface 23, thus achieving rapid alignment and improving construction efficiency.

[0035] Preferably, the traction assembly 5 is connected to or integrally formed with the fixed block 2, and the tips of the conical block 3 and the conical concave surface 23 are positioned opposite to the movable block 1. This design allows the traction assembly 5 to effectively pull the movable block 1 and the fixed block 2 via the connecting rope 4, achieving rapid docking of the flange.

[0036] Specifically, one end of the connecting rope 4 passes through the conical block 3 and the movable block 1 in sequence, and is fixedly connected to the first limiting ring 7 after passing through the positioning ring 6. The positioning ring 6 can switch between a first position and a second position. In the first position, the positioning ring 6 abuts against the first limiting ring 7 and the end of the movable block 1 away from the fixed block 2, respectively; in the second position, the positioning ring 6 moves along the direction of the connecting rope 4 and passes through the movable block 1. When the positioning ring 6 is in the first position, it can realize the process of fixing one end of the connecting rope 4 to the movable block 1. When the positioning ring 6 is in the second position, it can realize the extraction of the positioning ring 6 and the first limiting ring 7 from the movable block 1, thereby releasing the connection between one end of the connecting rope 4 and the movable block 1.

[0037] In one specific embodiment of this utility model, the projection of the first limiting ring 7 is located inside the projection of the positioning ring 6 along the length direction of the connecting rope 4. The positioning ring 6 has multiple protrusions integrally formed on its edge, and an embedding groove 12 is provided on the end face of the movable block 1 away from the fixed block 2. In a first position, the protrusions are embedded in the embedding groove 12; in a second position, the protrusions move through the movable block 1 along the direction of the connecting rope 4. This design allows for effective fixing or releasing between the positioning ring 6 and the movable block 1, enabling a quick assembly and disassembly process between the movable block 1 and the positioning ring 6.

[0038] Optionally, the movable block 1 is stepped, comprising an integrally formed first stop 11, a first sleeve 13, and a first connecting part 14 arranged sequentially. Both the first stop 11 and the first sleeve 13 are cylindrical structures. The first stop 11 abuts against the opposite side of one of the flanges, and an embedding groove 12 is provided on the end face of the stop. The first sleeve 13 passes through a bolt hole, and the first connecting part 14 is detachably connected to the conical block 3. The first connecting part 14 is a threaded post, and the end face of the conical block 3 away from the fixed block 2 is provided with internal threads. The threaded post and the internal threads are detachably connected.

[0039] Furthermore, the fixing block 2 is also stepped, including an integrally formed second stop 21 and a second sleeve 22. Both the second stop 21 and the second sleeve 22 are cylindrical structures. The second stop 21 abuts against the opposite side of another flange, and the second sleeve 22 passes through the bolt hole. The second sleeve 22 is provided with a conical concave surface 23 that matches the conical block 3. This structural design allows the movable block 1 and the fixing block 2 to be stably engaged in the bolt holes of the flange, and achieves rapid docking between the relative flange holes through the cooperation of the conical block 3 and the conical concave surface 23.

[0040] It should be understood that the movable block 1, the conical block 3, and the fixed block 2 of this utility model have various specifications and their dimensions are not unique, and are used to accommodate bolt holes of different sizes.

[0041] The traction assembly 5 includes two connecting rods 51 that are crossed and rotatably connected at the center. One end of one connecting rod 51 is integrally formed with the second stop part 21, and the other end of the connecting rope 4 passes through one end of the other connecting rod 51 and is fixedly connected to a second limiting ring 8, which abuts against the other end of the other connecting rod 51. The other ends of one and the other connecting rod 51 are respectively fixedly connected to the two ends of a power telescopic rod 52. The power telescopic rod 52 is an electric push rod, which is electrically connected to a control module, and the control module is electrically connected to a power source, which can be an external power source. By controlling the extension action of the electric push rod using the control module, the connecting rope 4 is effectively driven to pull the movable block 1 and the fixed block 2, realizing the rapid docking of the flange.

[0042] Specific operating steps of this utility model:

[0043] The first step is to ensure that the water pipeline to be installed is in a suspended state. The hoisting device can be an excavator with slings to ensure that the water pipeline is suspended in the air.

[0044] The second step involves initially connecting the water pipe to be installed with the existing water pipe, ensuring the flanges of the two pipes face each other. Then, install at least two of the quick-connection installation tools of this utility model, arranged in a circular array along the flange axis. Specifically, the conical block 3 is fixed to the first connecting part 14 of the movable block 1 using a threaded connection. Then, the movable block 1 and the fixed block 2 are respectively snapped into the opposite sides of the bolt holes on the two flanges. Ensure that the first stop part 11 of the movable block 1 abuts against the opposite side of one flange, and the second stop part 21 of the fixed block 2 abuts against the opposite side of the other flange.

[0045] Third, thread one end of the connecting rope 4 through the conical block 3 and the movable block 1 in sequence, then through the positioning ring 6 and fix it to the first limiting ring 7, ensuring that the first positioning ring 6 is in the first position. Ensure that the other end of the connecting rope 4 passes through the connecting rod 51 in the traction assembly 5 and is fixedly connected to the second limiting ring 8.

[0046] Step 4: As the water pipes to be installed are gradually lowered, multiple electric actuators are simultaneously activated using the control module. The extension of the electric actuators is controlled by the control module. The extension of the electric actuators causes the connecting rope 4 to pull the movable block 1 and the fixed block 2 closer together. During the process of the movable block 1 and the fixed block 2 approaching each other, the sliding connection between the conical block 3 and the conical concave surface 23 allows the two flanges to be positioned opposite each other and gradually approach each other. When the bolt holes of the two flanges are aligned, the action of the electric actuators stops.

[0047] Step 5: After aligning the bolt holes of the two flanges, and completing the lowering process of the installed water pipes, remove the hoisting device. Then, use bolts to connect and fix the remaining bolt holes of the two flanges. Using the control module, retract the electric push rod to separate the conical block 3 from the movable block 1, thereby positioning the positioning ring 6 in the second position. This allows the connecting rope 4 to pass through the movable block 1, removing the movable block 1 and the fixed block 2 from the bolt holes of the flanges. This completes the disassembly of the tools. Finally, use bolts to connect and fix the remaining bolt holes.

[0048] Through the above specific implementation methods, this rapid connection and installation tool for water conservancy pipelines can effectively solve the problems of difficult and inefficient connection of water conservancy pipelines in the existing technology, and improve the efficiency and quality of water conservancy pipeline laying.
