DETAILED DESCRIPTION

[0020] The following will be combined with the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1: Combination Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a stabilizing device for welding water conservancy engineering pipelines, comprising a frame 1, with limit rings 2 arranged on both sides of the top of the frame 1, and a set of stabilizing components 3 arranged on the surface of the limit rings 2. The ingenious design of this set of components enables the frame to remain stable when subjected to various loads;

[0022] The core part of the stabilizing component 3 is an array composed of a plurality of slide bars 31. These slide bars 31 are arranged in a circular array with the limiting ring 2 as the axis. They can slide freely on the limiting ring 2. The inner end of the slide bar 31 is fixedly connected with a protrusion 32, so that the slide bar 31 can maintain a stable position during the sliding process. In addition, the outer wall of the slide bar 31 is also sleeved with a damping spring 33. These damping springs 33 are located between the protrusion 32 and the limiting ring 2 to play a role of buffering and shock absorption.

[0023] The two ends of the limit ring 2 are also laterally slidably connected with a control ring 34, and the inner end of the control ring 34 is provided with an inclined groove 35, and the specifications of these inclined grooves 35 are adapted to the specifications of the slide bar 31, so that the slide bar can move freely in the inclined groove 35, thereby realizing accurate adjustment of the frame 1;

[0024] A movable seat 36 is provided at the bottom end of the control ring 34. The movable seat 36 is installed on the frame 1 by transverse sliding through a guide rod. At the same time, the movable seat 36 is also slidably connected to the outer wall of the control ring 34 through a slider. This connection mode enables the control ring 34 and the movable seat 36 to work together, further improving the stability of the frame.

[0025] A bidirectional screw rod 37 is also threadedly connected to the movable seat 36, and the bidirectional screw rod 37 is rotatably installed on the frame 1. By rotating the handle 38, the bidirectional screw rod 37 can be driven to rotate, thereby achieving precise control of the position of the movable seat 36. This design not only makes the frame 1 more stable and easier to adjust, but also improves the operability and reliability of the entire equipment.

[0026] In the embodiment of the present invention, the bidirectional screw rod 37 is driven to rotate by the handle 38. When the bidirectional screw rod 37 rotates, its unique thread design can drive the two moving seats 36 to move inward or outward at the same time. This design cleverly utilizes the principle of screw transmission and realizes the precise displacement of the moving seat 36 through a simple rotation action.

[0027] The moving seat 36 is connected to the slider. When the moving seat 36 moves, the slider will slide on the limit ring 2, driving the control ring 34 to move horizontally. This lateral movement is controlled by the trajectory of the limit ring 2, ensuring that the moving path of the control ring 34 is accurate and stable.

[0028] When the two control rings 34 move inward at the same time, they will push the slide bar 31 and the convex head 32 to move inward under the action of the inclined groove 35. At this time, the damping spring 33 will be in a stretched state, which increases the damping and stability of the system. This design cleverly uses the balance principle of mechanics, so that the convex head 32 can fit tightly on the surface of the pipeline to stabilize the pipeline.

[0029] The application of this stabilizing device greatly facilitates the workers' welding work on the pipeline. Due to the stabilizing effect of the protrusion 32 on the pipeline, the workers can weld more accurately and avoid possible deviation during the welding process. This not only improves work efficiency, but also ensures welding quality and reduces the defective rate.

[0030] Embodiment 2: Combination Figure 3 As shown, based on the first embodiment, the limit ring 2 is cleverly designed into a rotatable structure and is installed on the frame 1. This installation method not only allows the limit ring 2 to rotate flexibly when needed, but also effectively limits its range of motion, thereby ensuring the stability and safety of the mechanical equipment during operation;

[0031] The inner end outer wall of the limiting ring 2 is fixedly connected with a gear ring 21, which is a circular ring with a gear shape, and realizes transmission by meshing with other gears. Here, the function of the gear ring 21 is to mesh with the gear 24 on the driving rod 23, thereby driving the rotation of the limiting ring 2;

[0032] Next, let's look at the installation and driving method of the driving rod 23. A mounting seat 22 is fixedly connected to the inner side end of the frame 1, and the driving rod 23 is rotatably connected to the mounting seat 22. This rotatable connection method enables the driving rod 23 to rotate freely in the mounting seat, thereby driving the rotation of the limit ring 2.

[0033] Gears 24 are fixedly connected to both ends of the driving rod 23, and the gears 24 are meshed with the gear ring 21, which means that when the driving rod 23 rotates, the gears 24 thereon will drive the gear ring 21 to rotate, thereby further driving the rotation of the limit ring 2. This transmission method has the advantages of simple structure and reliable transmission, and can meet the requirements of mechanical equipment for limit ring driving;

[0034] In addition, a motor 25 fixedly mounted on the frame 1 is provided on one side of the mounting seat 22. The motor 25 serves as a source of driving force and is connected to the driving rod 23 through a pulley transmission member at its output end. This transmission method has the advantages of high transmission efficiency and low noise, and can ensure that the limit ring can rotate quickly and stably when needed.

[0035] In the embodiment of the present invention, when the motor 25 is started, it closely cooperates with the driving rod 23 through the pulley transmission member, ensuring that the driving rod 23 can rotate synchronously with the rotation of the motor 25. This design cleverly utilizes the advantages of the pulley transmission member, that is, it can achieve smooth and uniform rotation while maintaining a high transmission efficiency, avoiding vibration and noise caused by mechanical friction;

[0036] As the driving rod 23 rotates, the two gears 24 also start to rotate synchronously. The design of the two gears 24 carefully selects the appropriate number of teeth and tooth shape to ensure that a constant speed and direction can be maintained when transmitting torque. In addition, the close combination of the gears 24 and the ring gear 21 further enhances the stability and reliability of the transmission. This design not only simplifies the mechanical structure, but also improves the overall working efficiency.

[0037] When the gear 24 and the gear ring 21 work together, they will drive the two limit rings 2 to rotate synchronously on the top of the frame 1. The limit rings 2 are cleverly designed to effectively fix and support the pipeline to prevent it from deflecting or shaking during the rotation process. At the same time, the precise fit between the limit rings 2 and the frame 1 also ensures the stability and accuracy of the entire rotation process.

[0038] Through this carefully designed mechanical structure, the pipeline can achieve synchronous rotation driven by the limit ring 2. This rotation is not only accurate and smooth, but also the speed and direction of rotation can be adjusted as needed, thereby achieving precise adjustment of the pipeline welding position. This adjustment function is crucial to ensuring the welding quality because it can ensure the uniform distribution and accurate docking of the welds, and improve the strength and sealing of the welded joints.

[0039] The working principle of the stabilizing device for welding water conservancy project pipelines: the bidirectional screw rod 37 is driven to rotate by the handle 38. When the bidirectional screw rod 37 rotates, it can drive the two moving seats 36 to move inward or outward at the same time. The moving seat 36 cooperates with the slider to drive the control ring 34 located on the limit ring 2 to move horizontally. When the two control rings 34 move inward at the same time, the control ring 34 pushes the slide bar 31 and the protrusion 32 to move inward under the action of the inclined groove 35. At the same time, the damping spring 33 is in a stretched state, so that the protrusion 32 stabilizes the pipeline, which facilitates the staff's welding work on the pipeline and avoids the occurrence of welding offset during welding.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
