[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, further detailed description of the embodiments of the present disclosure will be made below in combination with examples and drawings, and the schematic embodiments of the present disclosure and the description thereof are only used to explain but not to limit the embodiments of the present disclosure.

[0026] As shown in Figure 1 , a pipeline butt joint device for hydraulic engineering of the present application comprises a quick-mounting clamp 1, a positioning frame 2, a load-bearing rib plate 3 and a tension spring 4.

[0027] The quick-mounting clamp 1 is used to provide the necessary mounting and dismounting speed for the pipeline to achieve quick connection. The quick-mounting clamp 1 has a manually adjustable function, and a threaded structure with a self-locking function is arranged inside, which can quickly reach the required force during screwing through manual control without accidental slipping. Further referring to Figure 3 , the quick-mounting clamp 1 also contains a specially customized rubber friction layer 12 to avoid damage to the pipeline caused by direct compression. The rubber friction surface adopts a unique beveled arc tooth 13 design. After the two pipelines are pushed together and locked, such a design allows the pressure to be more evenly distributed at the joint of the two pipelines, which not only increases the contact stability but also ensures the close combination between the surfaces without deviation or slipping.

[0028] The positioning frame 2 is arranged on both sides of the quick-mounting clamp 1 mentioned above. It not only plays a role in fixing the overall mechanism, but more importantly, it can adjust the height difference of different positions according to the needs to ensure that the centers of the two ends of the water pipe to be assembled are completely coincident, thereby achieving efficient and accurate alignment. This adjustment process can be operated and implemented through precise screw transmission or other mature mechanical means. The lifting amount can be easily controlled by adjusting the screw on the fine positioning device, so that the installation can be successfully completed even in complex engineering environments.

[0029] In order to increase the overall strength of the equipment and share part of the stress caused by the load, a load-bearing member, i.e., the load-bearing rib plate 3, is firmly welded on the back side of the quick-mounting clamp 1 and extends horizontally to the two side edges. As a reinforced support, it mainly bears the external load and transmits the pressure from the clamp, and provides a solid and stable assembly platform for other components, thereby ensuring the safety and reliability of the system during operation. At the same time, the presence of the load-bearing rib plate 3 also helps to protect various types of accessories behind it from impact damage.

[0030] The tension spring 4 is fixed at both ends of the quick-mounting clamp 1 and the load-bearing rib plate 3. By means of the characteristics of elastic potential energy storage and release, it always maintains a certain pre-tightness under no external force, ensuring that the connection can still maintain a high-strength fit even under the influence of vibration or external pulling.

[0031] In one embodiment, with particular reference to Figure 1 , the adjusting screw 11 of the pipeline butt joint device for hydraulic engineering of the present application has two threaded grooves 5 with opposite screw directions, which endows the adjusting screw 11 with the function of driving the quick-fit clamps 1 at different positions to move in opposite directions synchronously in a single operation, that is, when the adjusting screw 11 is rotated, the two ends make the quick-fit clamps 1 approach each other or separate to achieve the closed and open states according to the relative screwing-in or screwing-out mode, thereby achieving the effect of quickly aligning and clamping the pipeline interface. In the design scheme, the adjusting screw 11 is installed in the space formed between the quick-fit clamps 1 and the positioning frame 2, vertically penetrating the central position of the quick-fit clamps 1.

[0032] Specifically, the design of the bidirectional opposite threaded grooves 5 allows the technician to directly control the movement of the two quick-fit clamps 1 relative to the center line of the adjusting screw 11 by manually rotating the adjusting screw 11 with the special structure. During the pipeline butt joint operation, for example, when clamping is needed, the adjusting screw 11 is rotated counterclockwise, and the opposite threads on both sides of the screw push the two clamps along the preset trajectory to converge towards the center until they tightly contact and fix the two sections of pipelines to be butt jointed, while ensuring uniform clamping pressure to avoid affecting the butt joint quality due to insufficient or excessive pressure on one side. In addition, during unloading, the same precise control process can be achieved through reverse operation, effectively improving construction efficiency and operation convenience.

[0033] As shown in Figure 2 and Figure 4 , in one embodiment, the quick-fit clamps 1 of the pipeline butt joint device for hydraulic engineering of the present application are provided below with double-sided drive racks 6, and a drive gear 7 is installed between the double-sided drive racks 6. The bottom end of the drive gear 7 is connected to a drive motor 8. Through this structural layout, the rotation of the drive motor 8 can drive the drive gear 7 to move, and the drive gear 7 cooperates with the double-sided drive racks 6 to realize the directional movement of the racks in a specific path, thereby enabling the quick-fit clamps 1 connected thereto to achieve precise position adjustment and relative movement, ensuring that the two pipelines to be connected can be accurately aligned.

[0034] For example, when the operator starts the drive motor 8, the rotating power generated by the motor is directly transmitted to the drive gear 7. Since the gear is simultaneously engaged with the two racks, under the action of the rotating force, the gear rotates along the fixed axis. At the same time, according to the working principle of the rack and pinion, this rotation will make the two drive racks 6 move inward or outward by a certain distance. Since the drive racks 6 and the quick-fit clamps 1 are connected in a fixed or fixed manner, the two quick-fit clamps 1 will also move towards each other according to the same logic, thereby achieving the purpose of automatically and efficiently assisting the butt joint of the pipelines in the hydraulic engineering.

[0035] In one embodiment, referring to Figure 1 The positioning frame 2 of the pipeline butt joint device for hydraulic engineering of the present application is internally configured with a hydraulic adjusting system 10 and a guide shaft 9. This design aims to flexibly adjust the size of the internal cavity according to different pipeline diameters and ensure the height alignment accuracy during each butt joint operation, so that the device can adapt to the requirements of various pipeline diameter specifications. Specifically, the hydraulic adjusting system 10 cooperates with the guide shaft 9 to realize the self-adaptive adjustment function in different pipeline installation scenarios. The installation position of the hydraulic adjusting system 10 is located on both sides inside the positioning frame 2, while the guide shaft 9 is fixed around the hydraulic adjusting system 10, more specifically, it is arranged at the bottom of the hydraulic adjusting system 10 to provide guidance and stability for the extension and contraction movement of the system, while preventing positional deviation that may occur during the adjustment process.

[0036] The design of the positioning frame 2 ensures that it can be dynamically adjusted under the drive of the hydraulic adjusting system 10, and by changing the size of the internal cavity, it can adapt to the installation requirements of various pipeline specifications. In order to further improve the positioning accuracy, the guide shaft 9 is ingeniously arranged to ensure smooth movement during the entire working process. For example, the technical solution combining the hydraulic adjusting system 10 and the guide shaft 9 can be started by electric signal triggering and manual control switch. When adjustment is needed to adapt to new pipelines, the system activates the built-in hydraulic unit after receiving external instructions, pushes or shrinks the relevant components to adjust the internal cavity until it reaches the preset value or matches the actual used pipeline size. This design not only increases the application range of the equipment, but also improves the automation and intelligence level in pipeline engineering operations.

[0037] As shown in Figure 3 In one embodiment, the tension spring 4 of the pipeline butt joint device for hydraulic engineering of the present application has a telescopic positioning rod 41 built-in, which guides the tension spring 4 and prevents it from bending and deforming during work. The positioning rod 41 is installed inside the tension spring 4 and works together with the tension spring 4, ensuring that when axial stress occurs, the tension spring 4 can stretch and contract in the predetermined direction without deviation or distortion, ensuring stable operation of the system and prolonging the service life.

[0038] The device effectively overcomes the problem of abnormal deformation of the tension spring 4 due to the lack of necessary constraint mechanisms in the prior art. Further, in specific application scenarios, when the quick adjustment clamp 1 is quickly adjusted to butt joint two sections of pipeline, the tension spring 4 needs to withstand large external force changes, and the built-in telescopic structure can ensure its linear movement, thereby providing continuous and stable pressing force.

[0039] For example, to achieve this function, the positioning rod 41 can be made of high fatigue-resistant material, and its fit with the inner cavity of the tension spring 4 can be ensured by precision machining, while maintaining a certain gap tolerance to allow for slight thermal expansion and contraction, so that the two can work in harmony under various working conditions. This design not only enhances the overall stability of the structure, but also helps to simplify the on-site maintenance process.

[0040] In one embodiment, the load-bearing rib plate 3 of the pipeline butt joint device for hydraulic engineering of the present application is additionally provided with a reinforcing fin 31. The reinforcing fin 31 further enhances the overall structural strength through unique installation location and design, especially in resisting bending deformation and longitudinal tensile stress. To ensure its full functionality, the reinforcing fin 31 is precisely installed on the part of the load-bearing rib plate 3 extending along the quick-fit clamp 1 and is firmly combined with the load-bearing rib plate 3 using a strong and effective welding process.

[0041] The reinforcing fin 31 is made of high-strength material and provides additional support at key stress points of the load-bearing rib plate 3, preventing deformation or damage after long-term stress. Specifically, the reinforcing fin 31 is not only distributed along the longitudinal direction of the load-bearing rib plate 3, but also has appropriate thickness in the vertical direction, forming a multi-dimensional mechanical support framework, so that the entire device can maintain high stability under complex load conditions. This improvement enables the device to be used in a wider range of working environments, extending its service life and reducing maintenance costs.

[0042] For example, for high-pressure environments or large-span support requirements commonly encountered in hydraulic engineering, this design ensures better mechanical properties of the load-bearing rib plate 3 and the entire butt joint device. In actual operation, after completing the regular welding process of the load-bearing rib plate 3, the pre-processed reinforcing fin 31 is accurately placed in the designated position for secondary fixation. This combination is simple and efficient, achieving significant performance improvement without changing the original assembly process.

[0043] In actual operation, when the device is used, two pipes can be fixed together by the quick clamp 1. First, two pipes to be connected are respectively placed in the positioning frame 2, and the height of the positioning frame 2 is adjusted to ensure that the pipe shafts are consistent and accurately aligned. Then, the operator quickly closes the quick clamp 1 by rotating the adjusting screw 11 with self-locking threads, and the rubber friction layer 12 inside the quick clamp 1 will be close to the pipe surface to prevent the surface from being damaged and increase the friction effect. The contact end of the rubber friction layer 12 is designed as a bevel arc tooth 13, and as the quick clamp 1 is closed and pressed, the arc teeth can more stably and uniformly distribute the clamping force to the pipe surface, ensuring tight butt joint. In this process, the tension spring 4 will provide additional clamping force to further ensure the stability of the connection, and finally the bearing rib plate 3 provides the strength and stability required by the entire structure to ensure the tight and reliable connection between the pipes.
