Description

Technical Field

[0001] The utility model relates to the field of windbreak sheds, in particular to an overhead pipeline welding windbreak shed. Background Art

[0002] In industrial engineering construction, a large number of pipelines are assembled in single sections on the ground. After that, they need to be hoisted onto pipe supports and then welded between sections on high-altitude pipe supports. Because the wind is sometimes strong in the air, welding operations such as gas shielded welding and argon arc welding require windproof enclosures.

[0003] The utility model patent with authorization announcement number CN203757178U discloses an overhead pipeline welded windshield, which is mainly composed of clamps, bolts, frames, bars, and outer covers. The frame is welded by four symmetrically arranged columns and horizontal bars between the upper ends of each pair of adjacent columns. Bars are welded evenly between the left and right horizontal bars, two clamps are symmetrically welded at the lower ends of the columns on both sides, and an outer cover is provided on the frame.

[0004] The utility model is convenient and reliable to use and effectively ensures the high-altitude welding working environment.

[0005] However, the existing overhead pipe welding windshield can be fixed to the overhead pipe by a clamp ring, but it requires multiple bolts to install and fix, which is troublesome. In addition, the overall one-piece structure occupies a large space and is not easy to transport. Therefore, it needs to be improved. Utility Model Content

[0006] The utility model aims to provide an overhead pipeline welding wind shield, which solves the problems of the existing overhead pipeline welding wind shield being difficult to install and difficult to transport.

[0008] Preferably, a spring is provided inside the hollow sleeve, one end of the spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the inner surface of the hollow sleeve. By providing the spring, elastic force can be applied to the locking pin, so that it is always inserted into the locking block.

[0009] Preferably, a shift rod is fixedly connected to the outer side of the pin body of the locking pin, and the shift rod is slidably connected to the hollow sleeve. The arrangement of the shift rod facilitates the transverse pulling of the locking pin.

[0010] Preferably, a magnetic ring is slidably sleeved on the outer side of the rod body of the shift lever, and the magnetic ring is attracted to the hollow sleeve. The arrangement of the magnetic ring can prevent the shift lever and the locking pin from loosening.

[0011] Preferably, a limiting plate is fixedly connected to the top of the shifting rod, and the limiting plate and the shifting rod are an integrated structure. The setting of the limiting plate has a limiting effect on the magnetic ring.

[0012] Preferably, the locking mechanism includes two connecting blocks, each fixedly connected to the upper and lower jackets. Facing surfaces of the two connecting blocks are fixedly connected to internally threaded sleeves, the inner sides of which are threadedly connected to bidirectional screws. The provision of the locking mechanism facilitates installation of the upper and lower jackets on the overhead pipe.

[0013] Preferably, a knob is fixedly connected to the middle section of the bidirectional screw body, and the knob and the bidirectional screw are an integrated structure. The arrangement of the knob facilitates the rotation of the bidirectional screw.

[0014] Preferably, a guide rod is fixedly connected to one side of the upper jacket close to the lower jacket, and the guide rod is slidably connected to the lower jacket. The setting of the guide rod has a guiding effect when adjusting the spacing between the upper jacket and the lower jacket.

The utility model is provided with a combination of two sets of upper jackets and lower jackets, and each upper jacket is respectively provided with the same bracket one and bracket two, and bracket one and bracket two are connected by a hinge, so that the whole can be folded and stored after use, which is convenient for transportation, and after the bracket one and bracket two are unfolded, they can be locked by the locking pins and locking blocks on the front of the two to maintain stability.

[0017] 2. The utility model sets a locking mechanism between the upper jacket and the lower jacket. The locking mechanism includes components such as a connecting block, an internal threaded sleeve, a bidirectional screw, a knob and a guide rod. The distance between the upper jacket and the lower jacket can be controlled by the relative threaded movement between the bidirectional screw and the internal threaded sleeve. In this way, the whole can not only be clamped on the overhead pipe by the upper jacket and the lower jacket, which is more convenient than the installation method using bolts, but also utilizes the adjustable function to make the whole suitable for overhead pipes of different diameters, thereby increasing applicability.

[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 The locking mechanism 4 includes two connecting blocks 41, and the two connecting blocks 41 are fixedly connected to the upper jacket 2 and the lower jacket 3 respectively.
