Description

Technical Field

[0001] The utility model relates to the field of gas pipelines, in particular to a convenient gas pipeline welding device. Background Art

[0002] Gas pipeline is a pipeline system used to transport gas (such as natural gas, liquefied petroleum gas, etc.). Gas pipeline system is usually composed of pipes, valves, connectors, brackets, etc. Welding is a process that combines two or more metal or non-metal materials by heating or pressure. Welding is usually used to manufacture, repair and connect various components and structures. Portable gas pipeline welding device is usually designed for on-site gas pipeline welding work.

[0003] The existing gas pipeline welding is performed by placing the gas pipeline between two semi-arc iron rings of the equipment, then fixing it with screws, and then moving the iron rings to make the gas pipeline contact and then welding. The gas pipeline connection cannot be fixed. When the gas pipeline is offset, it is easy to cause the gas pipeline connection to offset, affecting the position of the weld and the quality of the gas pipeline welding.

[0004] Therefore, it is necessary to design a convenient gas pipeline welding device that can fix the gas pipeline connection, ensure the accuracy of the connection position, and ensure the quality of welding and the accuracy of the weld. Utility Model Content

[0006] A convenient gas pipeline welding device comprises a support frame, an electric push rod, a guide block, a first sliding frame, a first clamping block, a second sliding frame, a second clamping block, a connecting plate, a clamping mechanism and a rotating mechanism, wherein the electric push rod is connected to the front side of the lower middle part of the support frame, the guide block is connected to the front side of the middle part of the support frame, the first sliding frame is connected to the telescopic end of the electric push rod, the first sliding frame passes through the guide block, the first clamping block is connected to the first sliding frame, the second sliding frame is slidably connected to the front side of the guide block, the first clamping block is slidably connected to the second sliding frame, the second clamping block is connected to the upper middle part of the second sliding frame, the second clamping block is slidably connected to the first sliding frame, the connecting plate is rotatably connected to the upper right side of the guide block, the connecting plates are rotatably and slidably connected to the first sliding frame and the second sliding frame, the left and right sides of the upper part of the support frame are provided with clamping mechanisms for clamping the gas pipeline, and the clamping mechanisms are provided with rotating mechanisms for rotating the gas pipeline.

[0007] Furthermore, a bottom plate is provided at the rear side of the support frame, which is convenient for falling down for use.

[0008] Furthermore, the clamping mechanism includes a support block, a bidirectional screw and a third clamping block. The support blocks are connected to the left and right sides of the upper part of the support frame. The support blocks and the support frame are rotatably connected with a bidirectional screw. The bidirectional screw is threadedly connected to two upper and lower third clamping blocks, and the third clamping blocks are slidably connected to the support frame. By rotating the bidirectional screw, the third clamping blocks move inward at the same time under the action of the thread, thereby clamping the gas pipeline.

[0009] Furthermore, it also includes a rotating handle, and the upper part of the bidirectional screw rod is connected with a rotating handle, which is convenient for hand-holding and rotating the bidirectional screw rod.

[0010] Furthermore, the rotating mechanism includes a third sliding frame, a roller and a telescopic spring. The front side of the third clamping block is slidably connected to the third sliding frame, the inner side of the third sliding frame is rotatably connected to the roller, and a telescopic spring is connected between the third sliding frame and the adjacent third clamping block; the gas pipeline is contacted through the roller, thereby rotating the gas pipeline.

[0011] Furthermore, a limiting block is provided on the outer side of the third sliding frame to prevent the third sliding frame from sliding out.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model drives the first sliding frame to move downward through the electric push rod, and then drives the connecting plate to rotate, so that the second sliding frame moves upward, and the first clamping block and the second clamping block move inward at the same time, thereby fixing the gas pipeline connection, ensuring the accuracy of the connection position, avoiding deviation of the welding position due to pipeline movement, and ensuring the quality of welding and the accuracy of the weld.

[0013] 2. The utility model rotates the bidirectional screw rod in the opposite direction by rotating the handle, and the third clamping block moves inward at the same time under the action of the thread, thereby clamping and fixing the gas pipeline, ensuring that the position of the pipeline is stable and unchanged during welding, reducing the risk of pipeline movement or tilting during welding, reducing the occurrence of accidents, and improving the safety of welding.

[0014] 3. The roller of the utility model contacts the gas pipeline, thereby causing the third sliding frame to move outward, and the telescopic spring is stretched. The position of the gas pipeline connection can be adjusted by rotating the gas pipeline to adapt to welding at different angles, thereby ensuring the quality and integrity of the weld during the welding process.
