Description

Technical Field

[0001] This utility model relates to the technical field of pipeline welding, and in particular to a gas pipeline windproof welding device. Background Technology

[0002] Mine gas guide pipes are a type of guide pipe used in mining operations to stably transport associated gas from minerals. They are typically installed vertically inside the mine tunnel and guide the gas to the surface.

[0003] Existing gas pipeline windproof welding devices, such as the gas pipeline welding device for gas engineering disclosed in utility model patent application number 202520412061.2, mainly include a support plate, on which two sliders are slidably connected. Each slider is connected to a fastening component. A third fastening component is rotatably connected to an extension plate on one of the sliders. A sliding sleeve is slidably connected between the two extension plates, and bolts are threaded onto each extension plate. In use, the pipeline is fixed by the fastening components. When the two pipelines are close together, they are welded by the welding gun and welding rod. Holding the handle makes the slide block slide along the groove, thereby realizing continuous welding of the gas pipeline. After the slide block slides one revolution along the groove, the two pipelines are welded together.

[0004] However, gas pipelines are generally installed inside mine tunnels, where airflow is strong and wind speed is unstable. Most existing welding devices do not have windproof functions, and workers need to repeatedly adjust the position during the docking process, which is very troublesome and inefficient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gas pipeline windproof welding device that can not only shield the welding point to avoid airflow affecting the welding effect, but also facilitate the fixing and alignment of two sets of pipes, thereby improving work efficiency.

[0006] This utility model discloses a gas pipeline windproof welding device, including a support mechanism; it also includes a moving mechanism, a fixing mechanism, a windproof mechanism, and a welding mechanism. The moving mechanism is installed on the support mechanism and drives the fixing mechanism closer to the moving mechanism. The fixing mechanism is installed on the moving mechanism and fixes the pipeline. The windproof mechanism is installed on the fixing mechanism and prevents airflow from interfering with the welding. The welding mechanism is installed on the windproof mechanism and welds the pipeline. The operator uses the support mechanism to fix the first set of pipelines and fixes the second set of pipelines to the fixing mechanism. The moving mechanism drives the fixing mechanism and the second set of pipelines closer to the first set of pipelines, aligning the two sets of pipelines and eliminating the trouble of repeated adjustments. Then, the welding mechanism is started to weld the pipelines. The operator pulls the windproof mechanism, which drives the welding mechanism to rotate, so that the welding point is always located between the windproof mechanism and the pipeline, avoiding airflow affecting the welding effect.

[0007] Preferably, the support mechanism includes a base, a column, a first positioning ring, three sets of first cylinders, and three sets of first clamping plates. The bottom end of the base is placed on the working surface, the bottom end of the column is connected to the top end of the base, the first positioning ring is installed on the column, and an annular positioning groove is opened in the first positioning ring. All three sets of first cylinders are installed on the first positioning ring, and the three sets of first clamping plates are respectively installed on the three sets of first cylinders. The worker places the base in the welding position, places the first set of gas pipes into the inner first positioning ring, and starts the three sets of first cylinders to push the three sets of first clamping plates close to the pipes to fix the first set of gas pipes.

[0008] Preferably, the moving mechanism includes a lead screw box, a lead screw, a steering mechanism, and a crank handle. The bottom end of the lead screw box is connected to the top end of the base. The lead screw is rotatably installed inside the lead screw box. The steering mechanism is installed on the base and connected to the lead screw. The crank handle is installed on the steering mechanism. After the second set of pipes is fixed to the fixing mechanism, the crank handle is turned. The crank handle drives the lead screw to rotate through the steering mechanism. The lead screw drives the fixing mechanism and the second set of pipes to move closer to the first set of pipes.

[0009] Preferably, the fixing mechanism includes a movable seat, a second positioning ring, three sets of second cylinders, and three sets of second clamping plates. The movable seat is slidably installed in the screw box, the second positioning ring is installed on the movable seat, and an annular positioning groove is opened on the second positioning ring. All three sets of second cylinders are installed on the second positioning ring, and the three sets of second clamping plates are respectively installed on the three sets of second cylinders. The second set of pipes is placed in the second positioning ring, and the three sets of second cylinders are activated to push the three sets of second clamping plates close to the pipes to fix the second set of gas pipes. The screw drives the movable seat and the second set of pipes to approach the first set of pipes, so that the two sets of welded ends are aligned.

[0010] Preferably, the windproof mechanism includes a first arc plate, a windproof cloth, a second arc plate, and two sets of handles. The first arc plate is slidably installed in the annular positioning groove of the first positioning ring, the windproof cloth is installed on the first arc plate, and the second arc plate is installed on the windproof cloth and slidably installed in the annular positioning groove of the second positioning ring. The two sets of handles are respectively installed on the first arc plate and the second arc plate. After welding begins, the windproof cloth and the pipe are located on both sides of the welding point to avoid airflow affecting the welding effect. At the same time, the windproof cloth has a certain curvature, which can block the side wind. The worker holds the two sets of handles and pulls the first arc plate and the second arc plate to rotate along the annular positioning groove, driving the welding mechanism to perform annular welding on the pipe.

[0011] Preferably, the windproof cloth is made of multi-layer aluminum silicate fiber cloth; the multi-layer aluminum silicate fiber cloth is not only easy to fold and stretch, with a folded thickness of 15mm, and the volume is reduced by 70% after folding, but also can withstand a high temperature of 1000 degrees Celsius, preventing it from being ignited during the welding process.

[0012] Preferably, the welding mechanism includes an electric cylinder, a connecting plate, a spring, a welding torch, and a flexible limiting plate. The electric cylinder is mounted on the first arc plate, the bottom end of the connecting plate is connected to the top end of the electric cylinder, the spring is mounted on the connecting plate and connected to the first arc plate, the welding torch is mounted on the connecting plate, and the flexible limiting plate is mounted on the first arc plate. When the electric cylinder is activated, the connecting plate is raised and lowered, which in turn raises and lowers the welding torch to facilitate bringing the welding torch closer to the welding point. The welding torch then welds the pipe. At the same time, the spring pulls the connecting plate, causing it to bend slightly. Simultaneously, the flexible limiting plate limits the welding torch, causing it to tilt at a certain angle, which facilitates the first arc plate to rotate the welding torch.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff uses the support mechanism to fix the first group of pipes, and fixes the second group of pipes on the fixing mechanism. The moving mechanism drives the fixing mechanism and the second group of pipes to move closer to the first group of pipes, so that the two groups of pipes are aligned, saving the trouble of repeated adjustments. Then the welding mechanism is started to weld the pipes. The staff pulls the windproof mechanism, which drives the welding mechanism to rotate, so that the welding point is always located between the windproof mechanism and the pipe, avoiding the airflow from affecting the welding effect.
