Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] Example 1

[0026] like Figures 1-4As shown, this utility model proposes a pressure pipeline welding device, comprising a base 1, a mounting frame 2, and a bracket 3; the base 1 is connected to the mounting frame 2; and a clamping assembly is connected to the base 1. The clamping assembly includes a bracket 3 connected to the base 1, a support plate 301 connected to the bracket 3, a rotary motor 302 connected to the support plate 301, a rotating shaft 303 connected to the output end of the rotary motor 302, a gear 304 connected to the periphery of the rotating shaft 303, and an external fixing component connected to the gear 304; an inner fixing frame is connected to the periphery of the rotating shaft 303, and the inner and outer fixing components are used to fix and clamp the pressure pipeline. Two clamping assemblies are provided, both connected to the upper ends of the base 1, and one end of the bracket 3 is connected to a hydraulic cylinder, allowing one end of the clamping assembly to move via the hydraulic cylinder, thus cooperating with the other end of the clamping assembly to weld the pressure pipeline. The device is simple to operate, easy to use, and conveniently improves the efficiency of pressure pipeline welding.

[0027] Further explanation: The external fixing component includes a rack 305 connected to the outer wall of the gear 304. Four frames 306 are connected to the outer wall of the gear 304. Each frame 306 is connected to a cylinder b307 and has a groove. The piston rod of the cylinder b307 passes through the groove and connects to a moving plate 308. The moving plate 308 is connected to an external magnetic block 309. A slider a is connected to the outside of the frame 306 and is connected to an annular guide rail. The arc-shaped guide rail is connected to a support plate 301. A slider b is connected to the moving plate 308 and is connected to a moving groove, which is located on the frame 306. During the rotation of the frame 306, the slider a moves synchronously along the annular guide rail. During the movement of the moving plate 308 via the cylinder b307, the slider b moves along the moving groove. Through the slider a, slider b, annular guide rail, and moving groove, the stability of the external fixing component is conveniently increased, enhancing the clamping effect on pressure pipelines.

[0028] Further explanation: The external clamping component includes a sleeve 310 connected to the periphery of the rotating shaft 303. Four fixing rods 311 are connected to the outer wall of the sleeve 310. Each fixing rod 311 is connected to a connecting rod 312. The connecting rod 312 connects to an inner magnetic block 313, which is connected to the outer magnetic block 309. The fixing rods 311 are hollow internally, with an opening on one side connecting to the connecting rod 312. The connecting rod 312 is connected to the fixing rod 311 by bolts, facilitating adjustment of the fit range according to the size of the pressure pipeline and improving the usability of the clamping assembly.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, the pressure pipeline welding device proposed by this utility model, based on the above embodiment, also details the specific components such as the base 1 and the mounting frame 2, as well as their matching method.

[0031] To further explain, the base 1 is provided with a guide groove and a connecting groove. The connecting groove connects to the slider c, which is located below the bracket 3. An elongated guide rail is connected above the base 1. During the adjustment of the position of the bracket 3, which holds the component at one end, by means of a hydraulic cylinder, the slider c moves along the connecting groove, which facilitates and increases the smoothness of the movement of the holding component and improves the coordination of the components of the pressure pipeline welding device.

[0032] Further explanation: Mounting frame 2 is connected to drive motor 201. The output end of drive motor 201 is connected to rotating shaft 202. Rotating shaft 202 is connected to adjusting block 203. Connecting plates 204 are connected to both sides of adjusting block 203. A moving rod 205 is connected below connecting plate 204 and a guide rod 206 is connected to one side. Moving rod 205 is connected in guide groove, and guide rod 206 is connected in elongated guide rail. Clamping components are connected above connecting plate 204. By starting drive motor 201, drive motor 201 drives rotating shaft 202 to rotate, thereby adjusting the position of connecting plate 204 and electric telescopic column 207. During the adjustment process, moving rod 205 moves along moving groove, and guide rod 206 moves along elongated guide rail, facilitating convenient adjustment.

[0033] To further explain, the clamping component includes an electrically operated telescopic column 207 connected to the connecting plate 204. The telescopic end of the electrically operated telescopic column 207 is connected to a support frame 208. The support frame 208 is connected to a cylinder a209. The cylinder a209 is connected to the clamping plate 210 via a piston rod. By activating the cylinder a209, the piston rod of the cylinder a209 drives the clamping plate 210 to adjust, thereby facilitating the adjustment of the clamping plate 210 according to the pressure pipeline, conveniently clamping and fixing the pressure pipeline, and increasing the application range of the welding device.

[0034] To further explain, the clamping component also includes a telescopic rod 211 connected to the connecting plate 204. One side of the telescopic rod 211 is connected to a guide post 212, which is connected to the outside of the clamping plate 210. During the adjustment of the clamping plate 210 by the cylinder a209, the telescopic structure of the guide post 212 extends and retracts synchronously, facilitating the lateral movement of the clamping plate 210 and improving its ability to clamp and fix the pressure pipeline, thereby enhancing the practicality of the pressure pipeline welding device.

[0035] The working principle of this utility model is as follows: First, the pressure pipe is connected to a clamping assembly on one side. The applicable lengths of the fixing rod 311 and connecting rod 312 are adjusted according to the size of the pressure pipe. The connecting rod 312 drives the inner magnetic block 313 to adjust to the inner wall of the pressure pipe. After adjustment, the pressure pipe is connected to the outer wall of the inner magnetic block 313. Then, the cylinder b307 is activated. The piston rod of cylinder b307 drives the moving plate 308 to move. The moving plate 308 drives the outer magnetic block 309, which is connected to the outside of the pressure pipe. This allows the outer magnetic block 309 and the inner magnetic block 313 to clamp and fix the pressure pipe. Then, the system is activated. A hydraulic cylinder with a clamping component at one end moves along the base 1 toward the other end of the support 3, allowing the pressure pipeline to be welded and connected. The operator operates the welding of the pressure pipeline. According to the welding position, the rotary motor 302 is started. The output end of the rotary motor 302 causes the rotating shaft 303 to rotate. The rotating shaft 303 drives the gear 304, and the gear 304 drives the rack 305, causing the outer fixing part to rotate. The rotating shaft 303 also drives the sleeve 310, causing the inner fixing part to rotate. This rotation adjusts the welding position, thereby improving the efficiency of pressure pipeline welding and enhancing the use of the pressure pipeline welding device.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
