[0029] Example 1:

[0030] Please see Figures 1-7 A lattice column welding operation shed includes a rain cover 1, a second fixed rod 4, a threaded sleeve 12 and a lifting mechanism. A round rod sleeve 13 is threadedly connected to the outside of the threaded sleeve 12. A ring 14 is rotatably connected to the round rod sleeve 13. A fireproof cloth 15 is fixedly connected to the outside of the ring 14. The lifting mechanism is set inside the rain cover 1.

[0031] The lifting mechanism includes a threaded rod 116, a movable plate 117 is threadedly connected to the outside of the threaded rod 116, a second movable square rod 118 is fixedly connected to the outside of the movable plate 117, a support plate 1191 is fixedly connected to the bottom end of the second movable rod 118, and two lifting devices 119 are provided on the support plate 1191.

[0032] The tarpaulin 1 is equipped with an exhaust pipe 2, and a first fixing rod 3 is installed inside the tarpaulin 1. A second fixing rod 4 is fixedly connected to the first fixing rod 3. A first sliding sleeve 5 is slidably connected to the first fixing rod 3. A movable wheel 6 is fixedly connected to the bottom end of the first fixing rod 3. A threaded sleeve 12 is fixedly connected to the first fixing rod 3. The tarpaulin 1 is made of polyvinyl chloride coated fabric.

[0033] The first fixed rod 3 is rotatably connected to the second telescopic rod 8, and the first sliding sleeve 5 is rotatably connected to the first telescopic rod 7. The first telescopic rod 7 and the second telescopic rod 8 are rotatably connected at the middle.

[0034] The end of the first telescopic rod 7 away from the first sliding sleeve 5 is rotatably connected to the second telescopic rod 8. The end of the second telescopic rod 8 close to the first telescopic rod 7 is rotatably connected to the first telescopic rod 7. The second sliding sleeve 10 is slidably connected to the second fixed rod 4. The third telescopic rod 9 is rotatably connected to the second sliding sleeve 10. The third telescopic rod 9 is rotatably connected to the middle of the second telescopic rod 8.

[0035] The lifting mechanism also includes a connecting sleeve 111, which is fixedly connected to the second fixed rod 4. The bottom end of the connecting sleeve 111 is fixedly connected to a first movable square rod 112, and a second movable square rod 118 is slidably connected inside the first movable square rod 112. A movable plate 117 is slidably connected inside the second movable square rod 118.

[0036] The first movable square rod 112 is provided with a second bevel gear 115 and a first bevel gear 114. The first bevel gear 114 is meshed with the second bevel gear 115. The threaded rod 116 is fixedly connected to the bottom end of the second bevel gear 115. The rear end of the first bevel gear 114 is fixedly connected to a handle 113. The lifting device 119 is rotatably connected to a rotating stop plate 1192.

[0037] Working process: The first fixed rod 3 is manually pushed to move the entire device to the designated position. Then, by pulling the first fixed rod 3, the first telescopic rod 7 and the second telescopic rod 8 tend to rotate horizontally, causing the sliding sleeve 5 to move upward. At the same time, the third telescopic rod 9 moves towards the center, causing the second sliding sleeve 10 to move to both sides of the second fixed rod 4, thereby unfolding the tarpaulin 1 to cover the column legs of the lattice column. With the tarpaulin 1 covering the lattice column, the welding gas is treated without pollution by passing through the external welding fume purifier 2.

[0038] Manually rotate the round rod sleeve 13 to disengage it from the threaded sleeve 12. The round rod sleeve 13 moves downward, causing the fireproof cloth 15 to ground for protection.

[0039] The manually rotated handle 113 causes the first bevel gear 114 to rotate, which in turn drives the second bevel gear 115 to rotate. The rotation of the second bevel gear 115 drives the threaded rod 116 to rotate, causing the moving plate 117 to move downward. The downward movement of the moving plate 117 drives the second moving square rod 118 to move, so that the supporting plate 1191 contacts the ground. Then, the manually rotated rotating plate 1192 supports the angle steel of the lattice column, which facilitates the manual welding of the lattice column flange.

[0040] A light-transmitting window can be installed at an appropriate location on the tarpaulin 1. The light-transmitting window can be covered with a fireproof transparent curtain or equipped with lighting equipment inside to ensure sufficient light during operation.
