Description

Technical Field

[0001] The utility model relates to the relevant field of rainproof sheds, in particular to a rainproof shed for welding sites. Background Art

[0002] Site welding is different from factory welding. The welding conditions at the site are more complicated than those at the factory. For example, the components cannot be turned over after being in place, which affects welding. The climate changes greatly and high-altitude operation is required. The welding quality is affected by adverse natural climate factors such as wind, sun, rain, and fog. In addition, the poor ventilation inside the steel box girder and high-altitude operation make the construction environment harsh. On the other hand, the quality and accuracy of site welding are very critical, which directly affects the line shape of the completed bridge and the overall quality control. Therefore, the process evaluation conditions for site welding are more complicated, and more considerations should be given to high-altitude wind speed, low-temperature welding, etc.

[0003] Welding regulations for site welding in the external environment: It is not suitable to conduct welding on site when the temperature is below 0℃; when welding in windy or rainy weather, wind and rain protection measures should be taken; welding operations should not be carried out in moderate or heavy rain or when the wind force is greater than level 4. Therefore, a rain shelter is required at the welding site to provide wind and rain protection measures when welding in windy or rainy weather to avoid affecting the welding work on site.

[0004] At present, the welding rain shelter is mainly formed by welding steel into a basic frame, and then tying or fixing aluminum plates or other plates on the frame to form a rain shelter. However, in some seasons, rain is accompanied by strong winds, and the rain shelter with only a closed structure on the top cannot block the rainwater that enters the rain shelter obliquely from the sides, which further reduces the dry area in the rain shelter and affects the welding work. Utility Model Content

[0026] An intermediate connecting rod 3 is fixed to the inner end of the upper end between the two L-shaped support rods 2 at each end, and the cross section of the intermediate connecting rod 3 is circular to reduce the friction of the edge surface on the rainproof structure; a first fixing seat 11 is welded and fixed to the upper end of the outer end of the L-shaped support rod 2, and a rotating block 12 is connected to the first fixing seat 11 through an axis rotation, and a C-shaped fixing frame 13 is fixed to the outer ends of the two rotating blocks 12 at each end, and a transverse connecting rod 14 is transversely fixed inside the C-shaped fixing frame 13, and a through slide groove 22 is opened on the longitudinal connecting rod on the C-shaped fixing frame 13 along the outer end of the transverse connecting rod 14;

[0027] A rainproof roof 18 is commonly provided at the upper ends of the four supporting frames 1. The rainproof roof 18 is composed of side roofs 19, a middle connecting roof 20 and a middle roof 21. The middle connecting roof 20 is located at both ends of the middle roof 21, and the side roofs 19 are located at the outer ends of the middle connecting roof 20. The side roofs 19, the middle connecting roof 20 and the middle roof 21 are integrally formed, and the existing rainproof cloth structure is adopted. A slight margin is left at the position of the middle connecting roof 20, so that there is no excessive pulling force on the rainproof roof 18 itself when the connecting structure is rotated to different positions; the side roofs 19 are fixed to the upper end surface of the C-shaped fixing frame 13 along the outer part of the transverse connecting rod 14 and the upper end surface of the transverse connecting rod 14, and the two ends of the middle roof 21 are fixed to the C-shaped fixing frame 13.

[0028] Furthermore, a second fixed seat 16 is welded and fixed in the middle of the outer end of the L-shaped support rod 2, and a driving cylinder 17 is rotatably connected to the second fixed seat 16 via an axis. The output rod end of the driving cylinder 17 is rotatably connected to a sliding seat 15 via an axis. A rod body that slides along a through-slide groove 22 is provided in the sliding seat 15, and the upper end surface of the sliding seat 15 is lower than the upper end surface of the C-shaped fixing frame 13.

[0029] When used in rainy weather, the angle of the C-shaped fixing frame 13 is adjusted according to the wind direction of the season; the output rod end of the driving cylinder 17 pushes the sliding seat 15 to move, and the sliding seat 15 slides outward along the through slide groove 22 to make the C-shaped fixing frame 13 rotate and rise, and the side top 19 changes from a vertical state to an inclined state, and the side top 19 performs side shielding of rain.

[0030] When used on sunny days in summer, the output rod end of the driving cylinder 17 pushes the sliding seat 15 to move, and the sliding seat 15 slides outward along the through slide groove 22 to make the C-shaped fixing frame 13 rotate and rise, so that the side top 19 is transformed from a vertical state to a horizontal state, so that the overall area of ​​the rainproof top 18 is expanded, the area of ​​direct sunlight is reduced, and sunshade is performed.

The mobile roller 5 can push the rain shelter to move until it reaches the target location, and then the positioning cone 10 is used for support. The change of the supporting structure makes the device more convenient to move, and can be combined with the flexible characteristics of the rainproof top 18 to achieve overall folding, reducing the floor space when not in use.

[0032] When in use, turn the rotating handle 8 to make the threaded rod 7 rotate upward and the positioning cone 10 leave the ground; push the rainproof awning to move until it reaches the target location, push each group of supporting frames 1 to both sides respectively, so that the middle top 21 on the rainproof top 18 is unfolded, and then turn the rotating handle 8 in the opposite direction to make the threaded rod 7 rotate downward, and the positioning cone 10 is inserted into the ground for fixation.

[0033] When the rainproof shed is not needed, the rotating handle 8 is rotated to make the positioning cone 10 leave the ground, and then each group of supporting frames 1 is pushed inward to drive the output rod end of the cylinder 17 to shrink, and the rainproof shed is folded as a whole.
