Description

Technical Field

[0001] The utility model relates to the field of welding auxiliary equipment, in particular to a wind shield used for pipeline welding. Background Art

[0002] In order to ensure the welding technical requirements when implementing pipeline welding, gas shielded welding is usually used, among which CO2 gas shielded welding is the most widely used. However, welding wind speed (greater than or equal to 2m / s) is one of the important factors affecting the quality of CO2 welding. If the windproof measures are not taken in place during construction, pores will be generated in the weld. At present, in the absence of external auxiliary devices, operators will mainly increase the CO2 gas flow to offset the influence of wind speed, but it cannot completely and accurately eliminate poor welding, especially in outdoor construction. It is difficult to avoid the influence of wind. In view of this, a wind shield for pipeline welding is proposed. Summary of the invention

[0023] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model rather than to limit the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0024] In a specific embodiment, a wind shield for pipeline welding is provided, including a wind shield 1 and an adjustment ring 2. To achieve that both can be fixedly installed on the connected pipe section 4, a first connection end 1.1 is provided at one end of the wind shield 1, and a second connection end 2.1 is provided at one end of the adjustment ring 2. The first connection end 1.1 and the second connection end 2.1 are connected by a connector 3, so that the wind shield 1 and the adjustment ring 2 can be bound and fixed to the outer wall of the connected pipe section 4. To achieve wind shielding around the weld, a shroud 1.2 is provided at the opposite end of the first connection end 1.1 of the wind shield 1. The shroud 1.2 can be higher than the weld c and is provided around the weld c.

[0025] In this example, the first connecting end 1.1 and the second connecting end 2.1 are made of 8-10mm steel plate, and the enclosure 1.2 is made of 3mm steel plate; the part of the adjustment ring 2 used for bundling is a flexible metal strip, and the second connecting end 2.1 is installed at the end of the flexible metal strip. Preferably, the flexible metal strip is made of 10mm round steel, and the second connecting end 2.1 steel plate can be cut and welded to the round steel into a whole.

[0026] When in use, first adjust the pipeline at the construction site to meet the welding conditions, then install the adjustment ring 2 and the wind shield 1, and adjust the installation position so that the weld c is located in the middle of the wind shield 1 enclosure 1.2; then, adjust the connector 3 to pre-tighten the adjustment ring 2 and the wind shield 1 and fine-tune the installation position, and tighten them after confirming that they are accurate, so that the two are tightly tied to the welded pipe section. In order to achieve different connection methods between the wind shield 1 and the adjustment ring 2, the present application mainly designs the connector 3 into two structural forms, the first of which is a traditional screw-nut assembly, and in order to achieve the installation with the wind shield 1 and the adjustment ring 2, mounting holes are respectively provided at the first connection end 1.1 and the second connection end 2.1, the screw is installed in the mounting hole, and nuts are used for tightening and adjustment, thereby realizing the connection and fixation of the wind shield 1 and the adjustment ring 2. In order to further facilitate the loading and unloading of the adjustment ring 2 and the wind shield 1 from the pipeline during use, when the mounting hole is facing the first connection hole, the adjustment ring 2 and the wind shield 1 are connected to the pipe. A notch a is provided at the outer ends of the first connecting end 1.1 and the second connecting end 2.1, so that the screw and nut assembly can be installed in the mounting hole through the notch a. Therefore, the screw and nut can be loaded and unloaded from the side ends of each connecting piece, avoiding the need to remove the entire nut and screw from the mounting end, thereby improving ease of use; the second connecting piece 3 adopts a traditional hook and ring assembly, and the hook end or the ring end is correspondingly arranged at the first connecting end 1.1 and the second connecting end 2.1. When connected, the wind shield 1 and the adjustment ring 2 are connected and fixed by the buckling of the hook and ring.

[0027] In addition, to improve the convenience of installation, a magnet is provided on the wind shield 1 facing the pipe end. During installation and adjustment of the position, the wind shield 1 can be pre-fixed on the welding pipe by the magnet, which can also prevent the wind shield 1 from falling during installation, thereby improving operational safety.

[0028] Therefore, the enclosing plate 1.2 on the wind shield 1 can surround the position to be welded, and can prevent the wind from blowing toward the weld joint during welding, thereby eliminating the influence of wind on the welding quality during welding, avoiding the generation of bubbles in the weld joint, effectively improving the welding quality, and improving the welding qualification rate. In addition, the wind shield 1 is easy to load and unload, which can save the work of measuring wind speed and setting up temporary windproof measures at the construction site, reduce the preparation time, and effectively improve work efficiency.

[0029] In addition, the pipe weld is full-circle, while the wind shield of the present application is a non-full-circle structure, so when in use, it is necessary to shield the unwelded welds end by end, but when the wind shield is placed at the welded position, it will be affected by the protruding part of the weld, resulting in poor contact between the wind shield and the pipe wall and a gap. In view of this, a side groove b is opened at the position corresponding to the weld c on the inner side of the wind shield 1, so that the weld can enter the side groove b during installation to avoid interference with the weld, so that the wind shield 1 and the pipe wall are more closely attached. On this basis, in order to prevent wind from blowing into the weld from the side groove b at a high wind speed, fireproof mud is placed at the outer end of the side groove b to block the side groove b, and the fireproof mud can be used to directly block the side groove b during welding.

[0030] In order to make the height of the enclosure plate 1.2 consistent with the pipe wall for easy welding, the outer edge of the enclosure plate 1.2 is set to be an arc shape parallel to the outer wall of the connecting pipe section 4.

[0031] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the invention through the above description. The technical scope of the invention is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
