[0007] Preferably, two steel wire ropes are arranged on the outer surface of the rotating shaft. One end of the outer surfaces of the two steel wire ropes is fixedly connected to one side of the outer surface of the rotating shaft. The two steel wire ropes are wound around the outer surface of the rotating shaft. The outer surface of the cylindrical rod is rotatably connected to the inner wall of the guardrail. A torsion spring is arranged at the top end of the outer surface of the cylindrical rod. One end of the outer surface of the steel wire rope far away from the rotating shaft is fixedly connected to one end of the outer surface of the torsion spring. A rectangular groove is opened at the top end of the outer surface of the guardrail. The steel wire rope is located inside the rectangular groove. A plurality of rectangular blocks are fixedly connected to the bottom end of the outer surface of the standing plate. The left and right ends of the outer surface of the worm are respectively rotatably connected to the inner walls of the two rectangular blocks. A second gear is fixedly connected to a section of the outer surface of the gear rod close to the groove rod. A toothed plate is fixedly connected to one side of the inner wall of the sliding rod. The outer surface of the second gear is meshed with the outer surface of one side of the toothed plate. A square block is rotatably connected to one side of the outer surface of the groove rod.

Two first sliding grooves are opened at the bottom end of the outer surface of the standing plate. The inner walls of the two first sliding grooves are respectively slidably connected to second T-shaped blocks. The bottom end of the outer surface of the second T-shaped block is fixedly connected to the top end of the outer surface of the rectangular plate.

A second threaded rod is fixedly connected to the top end of the outer surface of the rotating shaft. A threaded block is threadedly connected to the outer surface of the second threaded rod. A U-shaped block is rotatably connected to the outer surface of the threaded block.

[0008] The effect achieved by the above components is: by setting a rectangular plate, after connecting the standing plate to the steel structure column, the rotating shaft can be controlled by turning the rotating shaft by hand, so that the two steel wire ropes on the outer surface of the rotating shaft are wrapped around the outer surface of the rotating shaft and detached from the outer surface of the coil spring at the top of the outer surface of the two cylindrical rods on the left and right sides of the rotating shaft to stretch the coil spring. At the same time, it will drive the cylindrical rod to rotate, and the worm is driven to rotate through the first gear. During the rotation of the cylindrical rod, the fourth gear and the first threaded rod are driven to rotate through the third gear. Since the first threaded rod is threadedly connected to the inner wall of the standing plate, the first threaded rod will move upward during the rotation, and the square is pulled upward by the first threaded rod to tilt the slot rod. During the rotation of the worm, the second gear is driven to rotate through the gear rod, and the sliding rod is driven to slide on the inner wall of the slot rod through the second gear and the tooth plate and push one end of the outer surface of the sliding rod. When the operating platform is not in use or disassembled, the threaded block can be rotated to make the threaded block move upward on the outer surface of the second threaded rod to release the position fixation of the U-shaped block on the rotating shaft, and then the coil springs at the top ends of the outer surfaces of the two cylindrical rods on the left and right sides of the rotating shaft will return to their original shape and pull the wire rope wrapped around the outer surface of the coil spring to restore the sliding rod and the rectangular plate to their original positions.

[0009] Preferably, two cylindrical pieces are fixedly connected to the outer surface of the rotating shaft, and the steel wire rope wound around the outer surface of the rotating shaft is located between the two cylindrical pieces.

[0010] The effect achieved by the above components is that the position of the wire rope on the outer surface of the rotating shaft can be fixed by arranging the cylindrical piece to prevent the wire rope from being detached from the outer surface of the rotating shaft after being wound into a circle on the outer surface of the rotating shaft.

[0011] Preferably, the outer surface of the cylindrical piece slides on the inner wall of the rectangular groove, and the two cylindrical pieces are respectively located at the middle end and the bottom end of the outer surface of the rotating shaft.

[0012] The effect achieved by the above components is that when the shaft is rotated, the outer surface of the cylindrical piece will slide on the inner wall of the rectangular groove to fix the angle between the shaft and the guardrail and increase the stability of the shaft when rotating.

[0013] Preferably, a cylindrical block is fixedly connected to the top end of the outer surface of the second threaded rod, and a plurality of protrusions are provided on the outer surface of the cylindrical block.

[0014] The effects achieved by the above components are as follows: Rotating the cylindrical block at the convex part can more conveniently control the rotation of the first threaded rod and the rotating shaft, and it is not easy to slip.

[0015] Preferably, positioning blocks are respectively fixedly connected to the left and right ends of the outer surface of the worm. One side of the outer surface of the two positioning blocks rotates on one side of the outer surface of the rectangular block.

[0016] The effects achieved by the above components are as follows: During the rotation of the worm, one side of the outer surface of the two positioning blocks will rotate on one side of the outer surface of the rectangular block. The angle between the worm and the standing plate can be fixed through the positioning blocks, increasing the stability when the worm rotates.

[0017] Preferably, a windproof device is arranged on the outer surface of the cylindrical rod. The windproof device includes a reel. The bottom end of the outer surface of the reel is fixedly connected to the top end of the outer surface of the cylindrical rod. A long rope is arranged on the outer surface of the reel. One end of the outer surface of the long rope is fixedly connected to one side of the outer surface of the reel. A number of first rope-passing blocks are fixedly connected to the outer surface of the guardrail. Two U-shaped rods are respectively fixedly connected to the left and right sides of the outer surface of the guardrail. Two positioning rods are respectively arranged at the left and right ends of one side of the outer surface of the guardrail. A third sliding groove is formed in the outer surface of the positioning rod. An L-shaped block is slidably connected to the inner wall of the third sliding groove. One end of the outer surface of the L-shaped block is fixedly connected to a rectangular rod. A windproof cloth is arranged on the outer surface of the U-shaped rod. The front and rear ends of the outer surface of the windproof cloth are respectively fixedly connected to one side of the outer surface of the rectangular rod and one side of the outer surface of the U-shaped rod.

[0018] The effects achieved by the above components are as follows: By arranging the windproof cloth, when the rotating shaft of the stabilizing device rotates to drive the cylindrical rod to rotate, it will drive the reel at the top end of the outer surface of the cylindrical rod to rotate. When the reel rotates, it will wind the long rope around the outer surface of the reel and pull the rectangular rod through the other end of the long rope, so that the rectangular rod slides through the L-shaped block on the inner wall of the third sliding groove to adjust the distance between the rectangular rod and the U-shaped rod, and unfold the windproof cloth on the outer surfaces of the U-shaped rod and the rectangular rod. The windproof cloth is used to block the inside of the standing plate, minimizing the influence of wind on the welding operation during the high-altitude welding operation as much as possible.

[0019] Preferably, two elastic ropes are arranged on the outer surface of the windproof cloth. The two elastic ropes are respectively located at the upper and lower ends of the outer surface of the windproof cloth. The front and rear ends of the outer surface of the elastic ropes are respectively fixedly connected to one side of the outer surface of the rectangular rod and one side of the outer surface of the U-shaped rod.

[0020] The effects achieved by the above components are as follows: When the rotating shaft of the stabilizing device returns to its original position, the long rope will be loosened or tightened. At this time, due to the elastic force of the elastic ropes, it will pull the rectangular rod to control the rectangular rod to slide through the L-shaped block on the inner wall of the third sliding groove to retract the windproof cloth.

[0021] Preferably, the windproof cloth is made of a fabric with a PTFE film coated on its surface.

[0022] The effects achieved by the above components are as follows: By setting the windproof cloth to be made of a fabric with a PTFE film coated on its surface, the windproof cloth has good wind-blocking performance and is fold-resistant, allowing for long-term use.

[0023] Preferably, on the left and right ends of the outer surface of the guardrail, second rope-passing blocks are respectively fixedly connected to both sides, and a section of the outer surface of the long rope is located inside the second rope-passing blocks.

[0024] The effects achieved by the above components are as follows: Through the second rope-passing blocks, the position of the long rope on the outer surface of the guardrail can be fixed, minimizing the possibility of the long rope accidentally winding around the outer surface of the guardrail.

[0025] In summary, the beneficial effects of the present invention are as follows:

[0026] By setting up the stabilizing device, after the welding worker stands on the standing board, the rotating shaft can be rotated through the cylindrical block, and the lengths of the steel wire rope wound around the outer surfaces of the cylindrical rod and the rotating shaft can be changed to control the sliding of the sliding rod on the inner wall of the groove rod, pushing the rectangular plate to fit on both sides of the outer surface of the steel structure column to fix the angle between the standing board and the steel structure column. The bottom end of the standing board can be supported by the groove rod and the sliding rod to increase the stability and safety when using the operation platform. By pulling the long rope to unfold the windproof cloth, the inside of the standing board can be blocked, minimizing the influence of wind on the welding operation during high-altitude welding.

A rectangular groove 27 is opened at the top of the outer surface of the guardrail 4. The steel wire rope 26 is located inside the rectangular groove 27. A plurality of rectangular blocks 29 are fixedly connected to the bottom end of the outer surface of the standing plate 1. The left and right ends of the outer surface of the worm 210 are respectively rotatably connected to the inner walls of the two rectangular blocks 29. A second gear 212 is fixedly connected to a section of the outer surface of the gear rod 211 close to the groove rod 214. A toothed plate 216 is fixedly connected to one side of the inner wall of the sliding rod 215.

The bottom end of the outer surface of the second T-shaped block 219 is fixedly connected to the top of the outer surface of the rectangular plate 220. Two second sliding grooves 221 are opened on one side of the outer surface of the rectangular plate 220. One end of the outer surface of the sliding rod 215 is rotatably connected to a first T-shaped block 217. The size and shape of the outer surface of the first T-shaped block 217 are adapted to the size and shape of the inner wall of the second sliding groove 221. The first T-shaped blocks 217 at one end of the outer surfaces of the two sliding rods 215 respectively slide on the inner walls of the two second sliding grooves 221 on one side of the outer surface of a rectangular plate 220.

By providing the rectangular plate 220, after connecting the standing plate 1 to the steel structure column, the rotating shaft 21 can be rotated by hand to control the rotation of the rotating shaft 21, so that the two steel wire ropes 26 on the outer surface of the rotating shaft 21 are wound around the outer surface of the rotating shaft 21 and separated from the outer surface of the torsion springs 25 at the top of the outer surfaces of the two cylindrical rods 24 on the left and right sides of the rotating shaft 21 to stretch the torsion springs 25.

During the rotation of the cylindrical rod 24, it will drive the fourth gear 224 and the first threaded rod 223 to rotate through the third gear 222. Since the first threaded rod 223 is threadedly connected to the inner wall of the standing plate 1,The first threaded rod 223 moves upward during the rotation, and the first threaded rod 223 moves upward to pull the block 225 to tilt the slot rod 214.

At the same time, it pushes the second T-shaped block 219 at the top end of the outer surface of the rectangular plate 220 to slide on the inner wall of the first slide groove 218 to press the rectangular plate 220 against the outer surface of the steel structure column to fix the angle between the station plate 1 and the steel structure column, and then rotate the threaded block The control screw block 227 moves downward on the outer surface of the second threaded rod 226, and the U-shaped block 228 is clamped on the top of the outer surface of the guardrail 4, fixing the position of the rotating shaft 21 to prevent the rotating shaft 21 from rotating. The bottom edge of the outer surface of the standing board 1 is supported by the groove rod 214 and the sliding rod 215. When the operating platform is not in use or disassembled, the screw block 227 can be rotated to move the screw block 227 upward on the outer surface of the second threaded rod 226 to release the U-shaped block 228 from fixing the position of the rotating shaft 21. Then, the coil springs 25 on the top of the outer surface of the two cylindrical rods 24 on the left and right sides of the rotating shaft 21 will return to their original position and pull the wire rope 26 around the outer surface of the coil spring 25 to restore the sliding rod 215 and the rectangular plate 220 to their original positions.

By arranging the cylindrical pieces 22, the position of the wire rope 26 on the outer surface of the rotating shaft 21 can be fixed to prevent the wire rope 26 from being separated from the outer surface of the rotating shaft 21 after being wound into a circle on the outer surface of the rotating shaft 21 as much as possible. The outer surface of the cylindrical piece 22 slides on the inner wall of the rectangular groove 27. The two cylindrical pieces 22 are respectively located at the middle end and the bottom end of the outer surface of the rotating shaft 21. When the rotating shaft 21 is rotated, the outer surface of the cylindrical piece 22 will slide on the inner wall of the rectangular groove 27 to fix the angle between the rotating shaft 21 and the guardrail 4, thereby increasing the rotation of the rotating shaft 21. For stability, the top of the outer surface of the second threaded rod 226 is fixedly connected to a cylindrical block 23, and the outer surface of the cylindrical block 23 is provided with a number of protrusions. Holding the protrusions and rotating the cylindrical block 23 can more conveniently control the rotation of the first threaded rod 223 and the rotating shaft 21 without slipping.

During the rotation of the worm 210, one side of the outer surface of the two positioning blocks 213 will rotate on one side of the outer surface of the rectangular block 29. The angle between the worm 210 and the standing plate 1 can be fixed by the positioning blocks 213 to increase the stability of the worm 210 during rotation.

The front and rear ends of the outer surface of the windproof cloth 39 are respectively fixedly connected to one side of the outer surface of the rectangular rod 35 and one side of the outer surface of the U-shaped rod 310. By providing the windproof cloth 39, when the stabilizing device 2 rotates the rotating shaft 21 to drive the cylindrical rod 24 to rotate, the reel 31 at the top end of the outer surface of the cylindrical rod 24 will be driven to rotate. When the reel 31 rotates, the long rope 32 will be wound around the outer surface of the reel 31, and the other end of the long rope 32 will pull the rectangular rod 35 to make the rectangular rod 35 slide through the L-shaped block 36 on the inner wall of the third chute 38 to adjust the distance between the rectangular rod 35 and the U-shaped rod 310, and unfold the windproof cloth on the outer surfaces of the U-shaped rod 310 and the rectangular rod 35. The windproof cloth is used to block the inside of the standing board 1, and as much as possible, reduce the influence of the wind on the welding operation during the high-altitude welding operation.

The front and rear ends of the outer surface of the elastic rope 311 are respectively fixedly connected to one side of the outer surface of the rectangular rod 35 and one side of the outer surface of the U-shaped rod 310. When the rotating shaft 21 of the stabilizing device 2 returns to its original position, the long rope 32 will be loosened or tightened. At this time, due to the elastic force of the elastic rope 311, the rectangular rod 35 will be pulled to control the rectangular rod 35 to slide through the L-shaped block 36 on the inner wall of the third chute 38 to retract the windproof cloth.

The second rope-passing blocks 34 can fix the position of the long rope 32 on the outer surface of the guardrail 4 as much as possible to avoid the long rope 32 being accidentally wound around the outer surface of the guardrail 4.

[0046] The working principle is as follows: When performing high-altitude welding operations on steel structure columns, first pass the column groove 5 in the middle of the standing plate 1 through the steel structure column, and then use tools such as stud nails to connect the standing plate 1 with the steel structure column. When the welding worker stands on the standing plate 1, the rotating shaft 21 can be rotated by hand to control the rotation of the rotating shaft 21, so that the two steel wire ropes 26 on the outer surface of the rotating shaft 21 are wound around the outer surface of the rotating shaft 21 and are separated from the outer surface of the coil spring 25 at the top of the two cylindrical rods 24 on the left and right sides of the rotating shaft 21 to stretch the coil spring 25. At the same time, it will drive the cylindrical rod 24 to rotate, drive the worm 210 to rotate through the first gear 28. During the rotation of the cylindrical rod 24, the fourth gear 224 and the first threaded rod 223 will be driven to rotate through the third gear 222. Since the first threaded rod 223 is threadedly connected to the inner wall of the standing plate 1, the first threaded rod 223 will move upward during rotation, pull the square block 225 through the upward movement of the first threaded rod 223 to make the groove rod 214 tilt. During the rotation of the worm 210, the second gear 212 will be driven to rotate, and the sliding rod 215 will be driven to slide on the inner wall of the groove rod 214 through the second gear 212 and the toothed plate 216, and the first T-shaped block 217 at one end of the outer surface of the sliding rod 215 will be pushed to slide downward on the inner wall of the second chute 221. At the same time, the second T-shaped block 219 at the top of the outer surface of the rectangular plate 220 will be pushed to slide on the inner wall of the first chute 218 to press the rectangular plate 220 against the outer surface of the steel structure column to fix the angle between the standing plate 1 and the steel structure column. Then rotate the threaded block 227 to control the threaded block 227 to move downward on the outer surface of the second threaded rod 226 to clamp the U-shaped block 228 on the top of the outer surface of the guardrail 4 to fix the position of the rotating shaft 21 to prevent the rotating shaft 21 from rotating. The outer surface of the bottom edge of the standing plate 1 is supported by the groove rod 214 and the sliding rod 215. During the rotation of the rotating shaft 21, the long rope 32 will be wound around the outer surface of the reel 31, and the other end of the long rope 32 will be used to pull the rectangular rod 35 to make the rectangular rod 35 slide through the L-shaped block 36 on the inner wall of the third chute 38 to adjust the distance between the rectangular rod 35 and the U-shaped rod 310. The windproof cloth on the outer surfaces of the U-shaped rod 310 and the rectangular rod 35 is unfolded. After the welding operation is completed, the threaded block 227 can be rotated to make the threaded block 227 move upward on the outer surface of the second threaded rod 226 to release the fixing of the position of the rotating shaft 21 by the U-shaped block 228. Subsequently, the coil springs 25 at the top of the two cylindrical rods 24 on the left and right sides of the rotating shaft 21 will return to their original state and pull the steel wire ropes 26 to be wound around the outer surface of the coil spring 25 to make the sliding rod 215 and the rectangular plate 220 return to their original positions. After the long rope 32 is loosened, due to the elastic force of the elastic rope 311, the rectangular rod 35 will be pulled to control the rectangular rod 35 to slide through the L-shaped block 36 on the inner wall of the third chute
