Therefore, they should not be construed as limitations on this utility model. Example 1

[0025] Reference Figures 1 to 3 A rainproof and sunshade canopy for construction on the top surface of a large-diameter pipeline includes: multiple legs 1 set above the pipeline 9, multiple telescopic legs 2 whose bottom is rotatably connected to the top of the legs 1, and a rainproof and sunshade canopy 4 whose bottom is rotatably connected to the top of the telescopic legs 2. The rainproof and sunshade 4 includes: a pair of parallel longitudinal beams 401, an anti-aging rainproof cloth 404, a pair of first crossbeams 402, and a pair of second crossbeams 405; the longitudinal beams 401, the first crossbeams 402, and the second crossbeams 405 form a foldable rectangular frame; one end of the first crossbeam 402 is welded to a longitudinal beam 401, the other end of the first crossbeam 402 is rotatably connected to one end of the second crossbeam 405, and the other end of the second crossbeam 405 is welded to another longitudinal beam 401; the anti-aging rainproof cloth 404 is fixed inside the foldable rectangular frame; in this embodiment, the anti-aging rainproof cloth 404 is connected to the foldable rectangular frame by rivets.

[0026] There are four outriggers 1 and four telescopic outriggers 2. The tops of two telescopic outriggers 2 are rotatably connected to the two second crossbeams 405, and the tops of the other two telescopic outriggers 2 are rotatably connected to the two first crossbeams 402. A scissor brace 3 is rotatably connected between the two telescopic outriggers 2 connected to the second crossbeams 405 and between the two telescopic outriggers 2 connected to the first crossbeams 402. It should be understood that the telescopic outriggers 2 are equipped with a limiting device to control the length of the telescopic outriggers 2.

[0027] Preferably, in this embodiment, the support leg 1 includes a first support block 101 with an arc-shaped bottom and a connecting seat 106 disposed on the top of the first support block 101; the connecting seat 106 is rotatably connected to the bottom of the scissor brace 3 and the telescopic support leg 2 respectively. Example 2

[0028] Based on Example 1, please refer to Figures 4 to 8 Preferably, in this embodiment, the telescopic outrigger 2 includes: a lower sleeve 201 whose bottom is rotatably connected to the connecting seat 106 by a flat-headed male and female locking bolt 5; an upper sleeve 202 whose bottom is fitted onto the lower sleeve 201; a limiting block 203 located at the top of the lower sleeve 201; a limiting block 204 located at the bottom of the upper sleeve 202; a limiting hole 205 penetrating the outer walls of the lower sleeve 201 and the upper sleeve 202; and a limiting bolt 206 passing through the limiting hole 205; the limiting hole 205 is located on the outer walls of the lower sleeve 201 and the upper sleeve 202 near the connecting seat 106; the top of the upper sleeve 202 is rotatably connected to the rainproof sunshade 4 by a flat-headed male and female locking bolt 5. In this embodiment, the maximum telescopic distance of the telescopic outrigger 2 is limited by a limiting block 203 at the top of the lower sleeve 201 and a limiting block 204 at the bottom of the upper sleeve 202, preventing the lower sleeve 201 from detaching from the upper sleeve 202; a limiting bolt 206 passing through the limiting hole 205 prevents the lower sleeve 201 from sliding against the upper sleeve 202. When the limiting bolt 206 passes through the limiting hole 205, a stable triangular structure is formed between the telescopic outrigger 2 and the scissor brace 3, as shown in the figure. Figure 4 As shown, the rainproof sunshade 4 is unfolded at this time. When the limiting bolt 206 has not passed through the limiting hole 205, the lower sleeve 201 and the upper sleeve 202 can slide together.

When the steel pipe is hoisted and positioned and the pipe 9 is connected and welded, this device can be supported on the top surface of the pipe 9. On sunny days, it can shield the welders working on the top of the pipe from the scorching sun, and on rainy days, it can shield the welders from the wind and rain.

The unused end of the connecting block 403 is rotatably connected to the second crossbeam 405, and the other end of the second crossbeam 405 is welded to another longitudinal beam 401. The unused end of the connecting block 403 and the second crossbeam 405 are rotatably connected to the locking bolt 5 via a flat-head male and female nail. It should be noted that the rotatable connection point between the connecting block 403 and the second crossbeam 405 is located below the rotatable connection point between the first connecting rod 301 and the second connecting rod 302.

[0031] like Figure 5 and Figure 6Preferably, in this embodiment, the support leg 1 further includes: a second support block 102 and a third support block 103 respectively disposed at both ends of the first support block 101; a limiting clip 105 respectively disposed on the second support block 102 and the third support block 103; and a through hole disposed on the connecting seat 106; the second support block 102 and the third support block 103 are connected to the first support block 101 by a connecting rope 104; a steel wire rope 6 passes through the limiting clip 105 and the through hole; the steel wire rope 6 passes through another support leg 1 at the same horizontal position, and both ends of the steel wire rope 6 are connected to the ground. By adding the second support block 102 and the third support block 103, the support leg 1 can be adapted to pipes 9 of different diameters. By pressing the first support block 101, the second support block 102 and the third support block 103 with the steel wire rope 6, the support leg 1 can be stably fixed above the pipe 9, preventing the rainproof sunshade 4 from being blown away by strong winds.

[0032] Preferably, in this embodiment, both ends of the wire rope 6 are provided with connecting buckles 7, and sandbags 8 are connected to the connecting buckles 7 by ropes. When in use, the sandbags 8 are generally placed directly on the ground to prevent the rainproof sunshade 4 from being pulled to one side of the pipe 9 due to the unbalanced weight of the sandbags 8 on both sides.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
