[0002] Water diversion projects refer to projects that artificially transport water resources from water sources to water-demanding areas, aiming to solve problems such as uneven distribution of water resources and insufficient water supply. The "South-to-North Water Diversion Project" is one of these projects. Water diversion projects can be divided into large-scale inter-basin water diversion projects, medium-sized regional water diversion projects, and small-scale local water diversion projects. During the construction of water diversion projects, pipeline docking is one of the unavoidable operations.

[0003] The existing pipe welding and butt joint equipment for water diversion and regulation projects includes a base, a displacement mechanism, an adjustment mechanism and a welding mechanism. The upper end surface of the base is provided with a displacement mechanism, and the upper side of the displacement mechanism is provided with an adjustment mechanism. The middle part of the upper end surface of the base is provided with a welding mechanism.

[0004] Although existing welding butt equipment can achieve circumferential welding of pipes, it cannot be flexibly adjusted according to different pipe diameters due to the fixed position design of the welding head, which limits its scope of use. In addition, the displacement mechanism and adjustment mechanism in these devices usually rely on electric components to drive, which is particularly inconvenient when constructing in areas with insufficient power supply. At the same time, the existing equipment is large in size, occupies a large space, and is not convenient for rapid transportation.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] like Figures 1 to 8 As shown, as an embodiment of the present invention, a pipe welding and docking device for water diversion and regulation engineering is provided, including a device base 100, two support frames 200 are symmetrically fixed on the device base 100, and the two support frames 200 are fixed with outer fixing sleeves 300 by bolts, and the inner side of the outer fixing sleeve 300 is fixed with an inner fixing sleeve 400, and grooves 410 are provided on both sides of the inner fixing sleeve 400, and a circular track slide 420 is provided in one of the grooves 410, and a ring-shaped slide groove 430 is provided on the outer side of one of the grooves 410, and the slide grooves 430 on the two inner fixing sleeves 400 are close to each other, and also include: The fixing mechanism 500 includes a fixing component 510, a linkage component 520 and a regulating component 530. The fixing components 510 are equidistantly distributed in a groove 410 on the inner fixing sleeve 400 away from the slide groove 430. One end of the fixing component 510 extends outside the groove 410. Two adjacent fixing components 510 are connected as a whole through the linkage component 520. One end of the regulating component 530 is fixed to and connected to one fixing component 510. The regulating component 530 can drive a connected fixing component 510 to deflect toward the axial direction close to the inner fixing sleeve 400 by manual rotation. One fixing component 510 drives two adjacent fixing components 510 to deflect synchronously through the linkage component 520. Similarly, multiple fixing components 510 located in the same groove 410 can complete the centering clamping and fixing of the pipeline by synchronous deflection, and the two inner fixing sleeves 400 can cooperate with the fixing mechanism 500 to independently center, clamp and fix the two pipelines to be connected, thereby ensuring the connection accuracy of the two pipelines. Even when working in areas with power shortage, it is ensured that the equipment can quickly center and clamp the pipeline, thereby improving the connection quality of the two pipelines. A welding mechanism, the welding mechanism comprising an assembly mechanism 600, a welding gun 700 and a control mechanism 800, the two ends of the assembly mechanism 600 respectively extend into the grooves 410 close to each other on the two inner fixed sleeves 400 and respectively slide with the slideways 420 in the two grooves 410, the welding gun 700 is fixed on the assembly mechanism 600, one end of the control mechanism 800 is rotatably mounted in the slide groove 430, the other end of the control mechanism 800 extends outside the slide groove 430 and is connected to the assembly mechanism 600, and the control mechanism 800 is concentric with the inner fixed sleeve 400; The assembly mechanism 600 can not only fix the welding gun 700, but also quickly adjust the welding angle, welding position and welding direction of the welding gun 700, so that the welding gun 700 can be accurately aligned with the butt joint of the two pipes, ensuring that the welding gun 700 can effectively and fully weld the butt joint of the two pipes. The control mechanism 800 can drive the assembly mechanism 600 and the welding gun 700 thereon to rotate by manually sliding in the slide groove 430, and the rotation center of the welding gun 700 is at the same position as the center of the pipe, ensuring that the welding gun 700 can accurately perform circular rotation welding around the butt joint of the two pipes, and even when working in areas with power shortage, the welding quality of the welding gun 700 to the pipe can be ensured.

[0029] In this embodiment, since the support frame 200 and the outer fixing sleeve 300 are connected by bolts, during the actual transportation process, the support frame 200 and the equipment base 100 are integrated, and the outer fixing sleeve 300, the inner fixing sleeve 400 and the fixing mechanism 500 and the welding mechanism thereon are integrated, so that the equipment can be quickly transferred to the area with power shortage, and the space occupied by the equipment during transportation can be reduced, thereby reducing the transportation cost and transportation time of the equipment; In the present device, the welding gun 700 is the only electrical component, and the remaining fixing mechanism 500, assembly mechanism 600 and control mechanism 800 are all manual components. In this way, in areas where electricity is scarce, the less electricity can be transmitted to the welding gun 700. At the same time, by manually controlling the remaining components, the rapid welding process of the two pipes can still be completed while ensuring the quality and efficiency of the docking of the two pipes.

[0030] like Figures 2 to 6 As shown, as a preferred embodiment of the present invention, the fixing assembly 510 includes a mounting block 511, a mounting frame 512, a V-shaped rod 513, a mounting shaft 514, a fixing base 515 and a fixing plate 516. The mounting blocks 511 are equidistantly distributed in the groove 410 in the circumferential direction. One side of the mounting block 511 extends out of the groove 410 and is fixed with a mounting frame 512. The mounting frame 512 is rotatably mounted with a mounting shaft 514. The two ends of the mounting shaft 514 are respectively connected to two adjacent mountings through a linkage assembly 520. The V-shaped rods 513 are equidistantly distributed on one side of the inner fixing sleeve 400 in the circumferential direction, and one end of the V-shaped rod 513 is fixedly connected to the mounting shaft 514. A fixing base 515 is rotatably mounted on the other end of the V-shaped rod 513. A fixing plate 516 is mounted on one side of the fixing base 515 close to the axis of the inner fixing sleeve 400. A regulating component 530 is mounted on one of the mounting frames 512, and the regulating component 530 is connected to the mounting shaft 514 on one of the mounting frames 512.

[0031] In this embodiment, the regulating component 530 can drive a mounting shaft 514 connected thereto to rotate by manual rotation, and one mounting shaft 514 drives two mounting shafts 514 adjacent thereto to rotate through the linkage component 520. Similarly, multiple mounting shafts 514 simultaneously drive their respective V-shaped rods 513 to deflect, and multiple V-shaped rods 513 drive their respective fixed bases 515 and fixed plates 516 to deflect toward the axial direction close to the inner fixed sleeve 400. Since the fixed base 515 can be rotated and adjusted to a certain extent on the V-shaped rod 513, during the deflection process, the fixed plate 516 moves along the fixed base 515 and the fixed plate 516. 5 can be rotated to a certain extent, so that it can fully and effectively conflict with the outer wall of the pipe with different diameters, ensuring the contact area between the fixing plate 516 and the outer wall of the pipe. The multiple fixing plates 516 can complete the centering clamping and fixing of the pipe by synchronous deflection and rotation adjustment, and improve the clamping stability of the pipe. The two inner fixing sleeves 400 can cooperate with the fixing mechanism 500 to independently center, clamp and fix the two pipes to be connected, ensuring the connection accuracy of the two pipes. Even when working in areas with power shortage, it is ensured that the equipment can quickly center and clamp the pipe, thereby improving the connection quality of the two pipes.

[0032] In a preferred embodiment, the V-shaped rod 513 can be replaced with other shapes that meet the requirements, such as an L-shaped rod or a T-shaped rod; A soft pad is fixed on the inner side of the fixing plate 516, which can not only increase the friction between the fixing plate 516 and the outer wall of the pipe and improve the clamping stability of the fixing plate 516 on the pipe, but also prevent the fixing plate 516 from causing damage to the outer wall of the pipe, thereby ensuring the quality of the pipe during the docking process and ensuring the aesthetics of the pipe.

[0033] like Figures 2 to 6 As shown, as a preferred embodiment of the present invention, the linkage assembly 520 includes a linkage rod 521 and a universal joint 522, the universal joint 522 is installed on both ends of the mounting shaft 514, the linkage rods 521 are circumferentially equidistantly distributed on one side of the inner fixing sleeve 400 and on the same side as the mounting frame 512, one linkage rod 521 is located between two adjacent mounting frames 512, and the two ends of one linkage rod 521 are respectively connected to two universal joints 522 close to each other on two adjacent mounting shafts 514.

[0034] In this embodiment, when one of the installation shafts 514 rotates, one installation shaft 514 drives the two universal joints 522 on its two ends to rotate, and one universal joint 522 drives a universal joint 522 on the adjacent installation shaft 514 through the linkage rod 521, so that multiple installation shafts 514 equidistantly distributed in the circumferential direction rotate synchronously, and multiple installation shafts 514 simultaneously drive their respective V-shaped rods 513 to deflect, and multiple V-shaped rods 513 drive their respective fixed bases 515 and fixed plates 516 to deflect toward the axial direction close to the inner fixed sleeve 400, thereby completing the centering clamping and fixation of the pipeline.

[0035] In a preferred embodiment, the linkage rod 521 preferably adopts a linkage rod 830 structure with locking and telescopic functions. The locking function on the linkage rod 521 is aimed at its telescopic function. When it is necessary to reduce or reduce the number of fixed plates 516, in order to ensure the centering clamping of the pipeline, the position of the mounting frame 512 and the mounting shaft 514 needs to be adjusted accordingly so that they are circumferentially equidistantly distributed on one side of the inner fixed sleeve 400. At this time, the linkage rod 521 is required to have a telescopic function so that it can effectively connect the adjusted multiple mounting shafts 514 to ensure the stability of the clamping work. After it completes the telescopic movement, the locking function can lock the linkage rod 521 and prevent it from telescopic movement. In this way, the installation position of the mounting frame 512 and the mounting shaft 514 can be limited to further improve the clamping stability of the pipeline.

[0036] like Figures 2 to 6 As shown, as a preferred embodiment of the present invention, the regulating component 530 includes a connecting frame 531, a worm 532, a worm wheel 533 and a regulating handle 534. The connecting frame 531 is vertically fixed on a mounting frame 512. The worm 532 and the regulating handle 534 are rotatably mounted on the connecting frame 531. The regulating handle 534 is fixedly connected to one end of the worm 532 and is concentric therewith. The worm 532 is meshed with a worm wheel 533 fixed on a mounting shaft 514.

[0037] In this embodiment, the regulating handle 534 is manually controlled to drive the worm 532 to rotate, the worm 532 drives the worm wheel 533 to rotate, and the worm wheel 533 drives a mounting shaft 514 connected thereto to rotate, thereby completing the centering clamping and fixation of the pipeline. The two inner fixing sleeves 400 can cooperate with the fixing mechanism 500 to individually center, clamp and fix the two pipelines to be connected, thereby ensuring the connection accuracy of the two pipelines. Even when construction operations are carried out in areas with a shortage of electricity, it is ensured that the equipment can quickly center and clamp the pipeline, thereby improving the connection quality of the two pipelines.

[0038] In a preferred embodiment, the transmission combination of the worm 532 and the worm wheel 533 has a certain self-locking property, so that after the connection with the regulating handle 534 is released, the fixing plate 516 can still stably clamp the pipeline to ensure the docking quality and efficiency of the pipeline.

[0039] like Figure 1 , Figure 4 and Figure 8 As shown, as a preferred embodiment of the present invention, the assembly mechanism 600 includes an assembly component 610 and a connecting component 620, the two ends of the assembly component 610 respectively extend into the grooves 410 close to each other on the two inner fixing sleeves 400 and respectively slide with the slideways 420 in the two grooves 410, the two ends of the assembly component 610 are respectively connected to the control mechanism 800 installed on the two inner fixing sleeves 400, the connecting component 620 is installed in the middle of the assembly component 610, and the welding gun 700 is installed on the connecting component 620.

[0040] In this embodiment, the connecting component 620 can adjust the position, angle and direction of the welding gun 700 on the assembly component 610, so that the welding gun 700 can be accurately aligned with the butt joint of the two pipes regardless of the diameter of the butt joint pipes, ensuring that the welding gun 700 can effectively and fully weld the butt joint of the two pipes. The control mechanism 800 can drive the assembly component 610 to slide in the slide 420 by manually sliding in the slide groove 430. The assembly component 610 drives the welding gun 700 to rotate through the connecting component 620, and the rotation center of the welding gun 700 is at the same position as the center of the pipe, ensuring that the welding gun 700 can accurately perform circular rotation welding on the butt joint of the two pipes, and even when working in areas with power shortages, the welding quality of the welding gun 700 on the pipe can be ensured.

[0041] like Figure 1 , Figure 4 and Figure 8 As shown, as a preferred embodiment of the present invention, the assembly component 610 includes an assembly rod 611, threaded teeth 612, a limiting plate 613, a pulley 614 and a limiting frame 615, the assembly rod 611 is located between the two inner fixed sleeves 400, and both ends of the assembly rod 611 are provided with threaded teeth 612 and limiting plates 613, the assembly rod 611 is movably connected to the control mechanism 800, the pulley 614 is slidably matched with the limiting plate 613, and the pulley 614 is slidably matched with the slideway 420, the assembly rod 611 is connected to the pulley 614 as a whole through the threaded teeth 612, the nut and the limiting plate 613, and the limiting frames 615 that are slidably matched with the side walls of the inner fixed sleeve 400 are also slidably installed at both ends of the assembly rod 611, and the threaded teeth 612 can fix the installation position of the limiting frame 615 by matching with the nut.

[0042] In this embodiment, the control mechanism 800 can drive the assembly rod 611 to rotate around the axis of the inner fixed sleeve 400 by manually sliding in the slide groove 430. The assembly rod 611 drives the pulley 614 to slide in the slideway 420 through the limit plate 613, and drives the connecting component 620 and the welding gun 700 thereon to rotate. Even when construction operations are carried out in areas with a shortage of electricity, the welding quality of the welding gun 700 on the pipeline can be ensured.

[0043] In a preferred embodiment, the limiting piece 613 preferably adopts a "I"-shaped sheet structure; The limiting frame 615 preferably adopts an "F"-shaped rod structure. Since the inner fixing sleeve 400 is an annular structure, the end faces of the limiting frame 615 that slide with the side wall of the inner fixing sleeve 400 are all arc-shaped surfaces, which ensures that the limiting frame 615 can slide freely on the side wall of the inner fixing sleeve 400. At the same time, the limiting frame 615 can limit the rotational movement of the assembly rod 611 so that it will not rotate, ensuring that the welding gun 700 can accurately weld the welding point of the pipeline.

[0044] like Figure 1 , Figure 4 and Figure 8 As shown, as a preferred embodiment of the present invention, the connecting assembly 620 includes a first mounting sleeve 621, a top screw 622, a second mounting sleeve 623 and a fixing clip 624, the first mounting sleeve 621 is locked on the outside of the assembly rod 611 by the top screw 622, the first mounting sleeve 621 is concentric with the assembly rod 611, and the first mounting sleeve 621 is horizontally slidably connected to the assembly rod 611, the second mounting sleeve 623 is locked on the outside of the first mounting sleeve 621 by the top screw 622, the second mounting sleeve 623 is circumferentially slidably connected to the first mounting sleeve 621, and two fixing clips 624 are fixed to one side of the second mounting sleeve 623, and the two fixing clips 624 fix the welding gun 700 by locking each other.

[0045] In this embodiment, the first mounting sleeve 621 slides horizontally on the assembly rod 611, which can change the horizontal position of the welding gun 700 so that it can be moved horizontally to a desired position. The second mounting sleeve 623 rotates on the first mounting sleeve 621, which can drive the welding gun 700 to rotate, thereby changing the welding angle and welding direction of the welding gun 700. At the same time, it can also change the distance between the welding gun 700 and the pipeline to a certain extent, so that the welding gun 700 can fully and effectively contact the docking point of the pipeline. In addition, the fixing clip 624 can fix different positions of the welding gun 700, thereby changing the straight-line distance between the welding gun 700 and the pipeline, expanding the adjustment stroke of the welding gun 700, so that the welding gun 700 can effectively weld pipelines of different diameters, thereby improving the docking efficiency and docking quality of the pipeline.

[0046] In a preferred embodiment, the fixing clip 624 preferably adopts a sheet structure with elasticity; The first installation sleeve 621 and the second installation sleeve 623 are preferably of a circular cylindrical structure.

[0047] like Figure 1 , Figure 5 and Figure 8 As shown, as a preferred embodiment of the present invention, the control mechanism 800 includes a circular slider 810, a control handle 820, a connecting rod 830 and a connecting sleeve 840, the circular slider 810 is slidably installed in the slide groove 430, the control handle 820 is arranged on the outside of the circular slider 810 and is fixedly connected to its outer wall, one end of the connecting rod 830 is fixedly connected to the outer wall of the circular slider 810, the other end of the connecting rod 830 extends between the two inner fixed sleeves 400 and is fixedly connected to the outer wall of the connecting sleeve 840, and the inner wall of the connecting sleeve 840 is slidably connected to the outer wall of the assembly rod 611.

[0048] In this embodiment, the control handle 820 is manually controlled to drive the circular slider 810 to slide in the slide groove 430, and the circular slider 810 drives the connecting rod 830 to rotate. The connecting rod 830 drives the assembly rod 611 to rotate around the axis of the inner fixed sleeve 400 through the connecting sleeve 840, thereby driving the welding gun 700 to rotate, and the rotation center of the welding gun 700 is at the same position as the center of the pipeline, ensuring that the welding gun 700 can accurately perform circular rotation welding on the two pipelines around the butt joint. Even when working in areas with a shortage of electricity, the welding quality of the welding gun 700 on the pipeline can be ensured.

[0049] In a preferred embodiment, the control handle 820 preferably adopts an annular columnar structure that is concentric with the inner fixing sleeve 400 .

[0050] The working principle of the present invention is: The control handle 534 is manually controlled to drive the worm 532 to rotate, the worm 532 drives the worm wheel 533 to rotate, the worm wheel 533 drives a mounting shaft 514 connected thereto to rotate, the mounting shaft 514 drives two universal joints 522 at both ends thereof to rotate, and the universal joint 522 drives a universal joint 522 on the mounting shaft 514 adjacent thereto through the linkage rod 521, so that multiple mounting shafts 514 equidistantly distributed in the circumferential direction rotate synchronously, and the multiple mounting shafts 514 drive their respective V-shaped rods 513 to deflect at the same time, and the multiple V-shaped rods 513 drive their respective fixed bases 515 and fixed plates 516 to deflect toward the axial direction close to the inner fixed sleeve 400. Since the fixed base 515 can be moved to a certain extent on the V-shaped rod 513, The rotation adjustment makes it possible for the fixed base 515 and the fixed plate 516 to be rotated to a certain extent on the fixed base 515 during the deflection process, so that the fixed plate 516 can fully and effectively collide with the outer wall of the pipes of different diameters, ensuring the contact area between the fixed plate 516 and the outer wall of the pipe. The multiple fixed plates 516 can complete the centering clamping and fixing of the pipes through synchronous deflection and rotation adjustment, and improve the clamping stability of the pipes. The two inner fixed sleeves 400 can cooperate with the fixing mechanism 500 to separately center, clamp and fix the two pipes to be butted, ensuring the butt-jointing accuracy of the two pipes, and ensuring that the equipment can quickly center and clamp the pipes even when working in areas with power shortages; The first mounting sleeve 621 slides horizontally on the assembly rod 611, which can change the horizontal position of the welding gun 700, so that it can be moved horizontally to a desired position. The second mounting sleeve 623 rotates on the first mounting sleeve 621, which can drive the welding gun 700 to rotate, thereby changing the welding angle and welding direction of the welding gun 700. At the same time, it can also change the distance between the welding gun 700 and the pipeline to a certain extent, so that the welding gun 700 can fully and effectively contact the butt joint of the pipeline. In addition, the fixing clip 624 can fix different positions of the welding gun 700, thereby changing the linear distance between the welding gun 700 and the pipeline, expanding the adjustment stroke of the welding gun 700, so that the welding gun 700 can effectively weld pipelines of different diameters; The control handle 820 is manually controlled to drive the circular slider 810 to slide in the slide groove 430, and the circular slider 810 drives the connecting rod 830 to rotate. The connecting rod 830 drives the assembly rod 611 to rotate around the axis of the inner fixed sleeve 400 through the connecting sleeve 840. The assembly rod 611 drives the pulley 614 to slide in the slideway 420 through the limiting piece 613, and drives the connecting assembly 620 and the welding gun 700 thereon to rotate, and the rotation center of the welding gun 700 is at the same position as the center of the pipe, ensuring that the welding gun 700 can accurately perform circumferential rotation welding on the two pipes around the butt joints. Even in the construction work in the area where electricity is scarce, the welding quality of the welding gun 700 on the pipe can be ensured; The above is the working principle of the pipeline welding and docking equipment used in the water diversion project.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
