[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 6 The inverted pipe welding windproof shed provided by this utility model includes a shed body 1, and the lower wall of the shed body 1 is provided with multiple sets of universal wheels;

[0031] To facilitate the hoisting of pipes, pipe clamps 4 are provided on the front and rear walls of the shed 1. The upper opening of the pipe clamp 4 is open, and the left and right inner walls of the pipe clamp 4 are wider at the top and narrower at the bottom.

[0032] When hoisting the pipeline, it can be directly and vertically lowered into the pipeline clamp 4. The inclined surface of the inner wall of the pipeline clamp 4 is used to guide the automatic centering and clamping of the pipeline, eliminating the process of horizontal adjustment of the hoisting path in traditional technology.

[0033] To achieve spatial decoupling between the canopy 2 and the pipe hoisting path, a canopy 2 is provided on the top of the canopy 1. Base plates 5 are fixedly connected to the front and rear sides of the canopy 1 near the lower wall. First connecting rods 6 and second connecting rods 7 are rotatably connected to the inner sidewalls of the base plates 5 in a left-right arrangement. The ends of the first connecting rods 6 and second connecting rods 7 furthest from the base plates 5 are rotatably connected to the outer wall of the canopy 2. A driving structure is provided between the base plates 5 and the second connecting rods 7 to drive the second connecting rods 7 to swing along the connection point between the base plates 5 and the second connecting rods 7. The ends of the two sets of first connecting rods 6 furthest from the base plates 5 are respectively connected to the front and rear walls of the canopy 2. Rotary connection, the ends of the two sets of second connecting rods 7 away from the base plate 5 are respectively rotatably connected to the front wall and the rear wall of the canopy 2. The base plate 5 and the canopy 2 form a double rocker mechanism through the first connecting rod 6 and the second connecting rod 7. The driving structure includes two sets of hydraulic cylinders 8. The two sets of hydraulic cylinders 8 are respectively rotatably connected to the upper wall of a set of base plates 5. The two sets of hydraulic cylinders 8 are respectively located on the right side of a set of second connecting rods 7. A rotating seat 9 is fixedly connected to the right wall of the second connecting rod 7. The extended shaft ends of the two sets of hydraulic cylinders 8 are respectively rotatably connected to a set of rotating seats 9. The base plate 5, the first connecting rod 6 and the second connecting rod 7 are all located on the left side of the pipe clamp 4.

[0034] Hydraulic cylinder 8 drives second link 7 to swing along the connection between base plate 5 and second link 7, so as to realize the linkage between first link 6 and second link 7 to drive the roof 2 to rotate around base plate 5 to open and close, so that the opening and closing trajectory of roof 2 has no spatial interference with the vertical hoisting path of pipe clamp 4, and realizes the synchronous operation of hoisting and opening and closing of roof 1.

[0035] In order to provide emergency driving capability in the event of failure of hydraulic cylinder 8, the end of the extension shaft of hydraulic cylinder 8 is rotatably connected to the rotating seat 9 by a connecting pin 10, which passes through the end of the extension shaft of hydraulic cylinder 8 and is threadedly connected to the rotating seat 9.

[0036] When the hydraulic cylinder 8 fails, after removing the connecting pin 10, the second connecting rod 7 can be manually pushed to rotate around the base plate 5 to maintain the opening and closing function of the roof 2, thus avoiding process interruption due to the failure of a single power source.

[0037] In order to adapt to the shape of the pipe outer wall when the canopy 2 is closed, a set of protective plates 3 are rotatably connected to the lower wall of the canopy 2 near the front and rear sides respectively. The shape of the protective plates 3 is adapted to the inner wall of the pipe clamp 4. The two sets of protective plates 3 are rotatably connected to the inner front wall and inner rear wall of the canopy 2 respectively through a set of hinges. The protective plates 3 can rotate towards the inside of the canopy 2 along the hinges.

[0038] When the canopy 2 is closed, the protective plate 3 is lowered, which, together with the pipe clamp 4, forms a seal on the pipe;

[0039] In order to fix the protective plate 3 in the storage position when the canopy 2 is opened, the upper inner wall of the canopy 2 is provided with a suspension structure for fixing the protective plate 3 when it is stored. Two sets of steel wire ropes 11 are fixedly connected to the upper inner wall of the canopy 2. The two sets of steel wire ropes 11 are distributed in front and behind. The lower end of each set of steel wire ropes 11 is provided with a collar 12. The protective plate 3 is pre-set with a hook to facilitate the fixing of the collar 12. The hook is a common anti-detachment limiting part on the market.

[0040] When the protective plate 3 rotates to the inside of the canopy 2, the pre-set hook on the protective plate 3 is connected to the collar 12 to prevent the protective plate 3 from shaking and interfering with the pipe hoisting path during the opening and closing of the canopy 2.

[0041] Working principle: During pipe hoisting, the pipe can be directly and vertically lowered into the pipe clamp 4. The inclined inner wall of the pipe clamp 4 guides the automatic centering and clamping of the pipe, eliminating the step of horizontal adjustment of the hoisting path in traditional technology. The hydraulic cylinder 8 drives the second connecting rod 7 to swing along the connection between the base plate 5 and the second connecting rod 7, so that the first connecting rod 6 and the second connecting rod 7 drive the canopy 2 to rotate and open around the base plate 5 in linkage. This ensures that the opening and closing trajectory of the canopy 2 has no spatial interference with the vertical hoisting path of the pipe clamp 4, and realizes synchronous operation of hoisting and opening and closing of the canopy 1. When the hydraulic cylinder 8 fails, the connecting pin 10 can be removed, and the second connecting rod 7 can be manually pushed to rotate around the base plate 5 to maintain the opening and closing function of the canopy 2, avoiding the interruption of the process due to the failure of a single power source. When the canopy 2 is closed, the protective plate 3 is lowered, which, together with the pipe clamp 4, forms a seal on the pipe. When the protective plate 3 rotates to the inside of the canopy 2, the pre-set hook on the protective plate 3 is connected to the collar 12 to prevent the protective plate 3 from shaking and interfering with the pipe hoisting path during the opening and closing of the canopy 2.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
