Description
Technical Field
[0001] This utility model belongs to the field of construction platform technology, and relates to a pressure steel pipe welding construction platform, and in particular a safe construction platform for pressure steel pipe welding construction. Background Technology
[0002] When performing pressure steel pipe welding, the use of a construction platform is crucial. The construction platform can withstand the weight of welding equipment, materials, and workers, providing workers with a fixed workspace and reducing the risk of falls when working at heights. The construction platform provides a work surface at a suitable height, allowing workers to perform welding operations more conveniently and reducing fatigue caused by improper posture. However, most existing safety construction platforms for pressure steel pipe welding still have problems that need to be solved.
[0003] Harmful waste gases are generated during the welding of pressure steel pipes. However, most existing safety construction platforms for pressure steel pipe welding lack the function of treating these waste gases, which generally dissipate naturally into the air. Without effective treatment, these waste gases directly enter the atmosphere, reducing air quality, polluting the surrounding environment, and can also be inhaled by workers, seriously affecting their respiratory system and overall health. Therefore, it is necessary to design a safety construction platform for pressure steel pipe welding to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a safe construction platform for pressure steel pipe welding. The technical problem this utility model aims to solve is that most existing safe construction platforms for pressure steel pipe welding lack the function of treating exhaust gases. Direct emissions will pollute the surrounding environment and may also be inhaled by workers, seriously affecting their respiratory system and overall health.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A safe construction platform for welding pressure steel pipes includes a construction platform with two first fixed seats fixedly connected to each of its two end supports. A common drive screw is mounted on each of the two first fixed seats at the same end. The drive screw is rotatably connected to the first fixed seat. A screw nut is fitted onto the drive screw, and the screw nut is adapted to the drive screw. A movable plate is fixedly connected to the outer wall of the screw nut. An upper clamping plate is fixedly connected to the bottom of the movable plate. Two limiting rods pass through the upper clamping plate and are slidably connected to the upper clamping plate. The bottom of each of the two limiting rods at one end is fixedly connected to the same lower clamping plate. The bottom of the lower clamping plate is fixedly connected to a mounting base. A roller is provided on the mounting base, and the roller is rotatably connected to the mounting base. A guide plate is provided at the bottom of the roller, and the guide plate is fixedly connected to the support of the construction platform. A common air collecting hood is provided between the upper and lower clamping plates at the same end. A pipe is fixedly connected to the input end of the air collecting hood. A fan is provided at the end of the pipe away from the air collecting hood. The pipe is connected to the input end of the fan, and an activated carbon filter is fixedly connected to the output end of the fan.
[0007] The working principle of this utility model is as follows: The air collector is placed on the lower clamping plate, causing the drive screw to rotate. The drive screw then moves the screw nut, which in turn moves the moving plate. The moving plate moves the upper clamping plate, which in turn moves the limiting rod. The limiting rod moves the lower clamping plate, which in turn moves the air collector and the mounting base. The mounting base then moves the rollers along the inclined surface of the guide plate. During this movement, the rollers rise, causing the mounting base to rise, which in turn causes the lower clamping plate to rise. The lower clamping plate then... This will cause the limit rod to rise, and the lower clamping plate to rise and move closer to the upper clamping plate until it contacts the upper clamping plate. When the roller moves to the top horizontal surface of the guide plate, the lower clamping plate will contact the upper clamping plate. The upper and lower clamping plates will then clamp the air collection hood, thus completing the installation of the air collection hood. Start the fan to draw the exhaust gas generated during welding into the air collection hood, and then filter it through the pipe and fan into the activated carbon filter. Continue to rotate the drive screw to adjust the position of the air collection hood. Its position can be adjusted according to changes in the welding position to ensure that harmful gases can be drawn in and treated in a timely manner.
[0008] A guide rod is inserted through the top of the movable plate, the movable plate is slidably connected to the guide rod, and the guide rod is fixedly connected to the first fixed seat.
[0009] With the above structure, the moving plate will move along the guide rod, ensuring the stability of the moving plate during movement.
[0010] A worm gear is fixedly connected to one side of the drive screw, and a worm is provided at the bottom of the worm gear to cooperate with it.
[0011] Both ends of the worm are fitted with second fixed seats, and the worm is rotatably connected to the second fixed seats.
[0012] The second fixed seat is fixedly connected to the construction platform.
[0013] A rotating wheel is provided on one side of the second fixed base, and the two rotating wheels are respectively fixedly connected to two worm gears.
[0014] Compared with the prior art, the safety construction platform for pressure steel pipe welding of this utility model has the following advantages:
[0015] 1. In this utility model, by employing an activated carbon filter to treat the collected waste gas, the waste gas is treated by the activated carbon filter before being discharged into the atmosphere. This effectively solves the problem mentioned in the background art that most existing safety construction platforms for pressure steel pipe welding construction lack the function of treating waste gas. Waste gas generally dissipates naturally into the air. If waste gas enters the atmosphere directly without effective treatment, it will reduce air quality, pollute the surrounding environment, and be inhaled by workers, seriously affecting their respiratory system and overall health. This invention achieves the technical effect of significantly reducing the concentration of harmful gases during the welding process, protecting the health and safety of workers, and also helping to improve the working environment.
[0016] 2. In this utility model, due to the use of upper and lower clamping plates to clamp and fix the air collecting hood and the adjustable position of the air collecting hood, the lower clamping plate will also move during the adjustment of the position of the upper clamping plate. During the movement, the lower clamping plate will rise and approach the upper clamping plate. The upper and lower clamping plates can clamp and fix the air collecting hood. Continuing to rotate the drive screw can adjust the position of the air collecting hood, thereby achieving the technical effect of facilitating the installation and disassembly of the air collecting hood, adjusting the position of the air collecting hood according to the change of the welding position, and ensuring that harmful gases can be drawn in in a timely manner.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0024] like Figure 1 - Figure 5 As shown, a safety construction platform for welding pressure steel pipes includes a construction platform 1. Two first fixed seats 2 are fixedly connected to the supports at both ends of the construction platform 1. A single drive screw 3 is installed on each of the two first fixed seats 2 at the same end, rotatably connecting the drive screw 3 to the first fixed seat 2. A screw nut 4 is fitted onto the drive screw 3, and the screw nut 4 is compatible with the drive screw 3. A movable plate 5 is fixedly connected to the outer wall of the screw nut 4. An upper clamping plate 6 is fixedly connected to the bottom of the movable plate 5. Two limiting rods 7 pass through the upper clamping plate 6, slidably connecting the limiting rods 7 to the upper clamping plate 6. A single lower clamping plate 8 is fixedly connected to the bottom of each of the two limiting rods 7 at the same end. A mounting base 9 is fixedly connected to the bottom of the lower clamping plate 8. A roller 10 is installed on the mounting base 9, rotatably connecting the roller 10 to the mounting base 9. A guide plate 11 is installed at the bottom of the roller 10, and the guide plate 11 is fixedly connected to the construction platform 1. The support of the construction platform 1 has a common air collection hood 12 between the upper clamping plate 6 and the lower clamping plate 8 at the same end. The input end of the air collection hood 12 is fixedly connected to a pipe 13. A fan 14 is installed at the end of the pipe 13 away from the air collection hood 12. The pipe 13 is connected to the input end of the fan 14. An activated carbon filter 15 is fixedly connected to the output end of the fan 14. A guide rod 16 is passed through the top of the moving plate 5. The moving plate 5 is slidably connected to the guide rod 16. The guide rod 16 is fixedly connected to the first fixed seat 2. A worm gear 17 is fixedly connected to one side of the drive screw 3. A worm 18 is provided at the bottom of the worm gear 17. A second fixed seat 19 is sleeved at both ends of the worm 18. The worm 18 is rotatably connected to the second fixed seat 19. The second fixed seat 19 is fixedly connected to the construction platform 1. A rotating wheel 20 is provided on one side of the second fixed seat 19. The two rotating wheels 20 are fixedly connected to the two worms 18 respectively.
[0025] The working principle of this utility model is as follows: During use, the fan 14 is started to draw the exhaust gas generated during welding into the air collection hood 12, which then flows along the pipe 13 and fan 14 into the activated carbon filter 15 for filtration. Alternatively, the air collection hood 12 can be held by hand to collect the exhaust gas. When installing the air collection hood 12, it is placed on the lower clamping plate. The operator then rotates the rotating wheel 20, which drives the worm gear 18 to rotate. The worm gear 18 drives the worm wheel 17 to rotate, which in turn drives the drive screw 3 to rotate. The drive screw 3 then moves the screw nut 4, which in turn moves the moving plate 5. The moving plate 5 then moves the upper clamping plate 6, which in turn moves the limiting rod 7. The limiting rod 7 then moves the lower clamping plate 8, which in turn moves the air collection hood 12 and the mounting base 9. The mounting base 9 then moves the roller 10 along the inclined surface of the guide plate 11. During this movement, the roller 10 rises, which in turn moves the mounting base 9. This will cause the lower clamping plate 8 to rise, which in turn will cause the limiting rod 7 to rise. The lower clamping plate 8 moves upward and moves closer to the upper clamping plate 6 until it contacts the upper clamping plate 6. When the roller 10 moves to the top horizontal surface of the guide plate 11, the lower clamping plate 8 will contact the upper clamping plate 6. The upper clamping plate 6 and the lower clamping plate 8 will then clamp and fix the air collector hood 12, thus completing the installation of the air collector hood 12. Continuing to rotate the drive screw 3 will adjust the position of the air collector hood 12. Its position can be adjusted according to changes in the welding position. To ensure that harmful gases can be promptly absorbed and treated, when it is necessary to remove the air collection hood 12 from the upper clamping plate 6 and the lower clamping plate 8, rotate the rotating wheel 20 in the opposite direction so that the roller 10 moves from the horizontal plane of the guide plate 11 to the inclined plane. Under the action of gravity, the lower clamping plate 8 will descend and move away from the upper clamping plate 6, thereby releasing the clamping and fixing of the air collection hood 12. The air collection hood 12 can then be removed and held by hand for collecting waste gas, or the air collection hood 12, pipe 13, fan 14 and activated carbon filter 15 can be removed for maintenance.
[0026] In summary, this invention can significantly reduce the concentration of harmful gases during the welding process, protect the health and safety of workers, improve the working environment, facilitate the installation and disassembly of the air collection hood, and adjust the position of the air collection hood according to changes in the welding position to ensure that harmful gases can be inhaled in a timely manner.
