[0029] like Figure 1-5As shown, this utility model provides an operating platform for steel structure welding, including an operating table 10. A lifting assembly 20 is provided on the bottom side of the operating table 10. The lifting assembly 20 includes an outer cylinder 201, a moving frame 203, a support frame 207, a motor 208, and a lead screw 209. The moving frame 203 is located on the outside of the outer cylinder 201, the support frame 207 is located on the front side of the moving frame 203, the motor 208 is located on the upper inside of the outer cylinder 201, and the lead screw 209 is located at the output end of the motor 208.

[0030] The movable base 30 is located at the bottom of the outer cylinder 201. The movable base 30 includes a drive motor 302, a drive wheel 303 and a driven wheel 304. The drive motor 302 is located inside the base 301, the drive wheel 303 is located at the output end of the drive motor 302, and the driven wheel 304 is located on the front and rear sides of the drive wheel 303.

[0031] Furthermore, this embodiment also includes a secondary lifting assembly, which is disposed between the outer cylinder 201 and the base 301. The secondary lifting assembly includes a telescopic column 305 and a hydraulic push rod 306. The bottoms of the telescopic column 305 and the hydraulic push rod 306 are screwed to the base 301. The secondary lifting assembly is provided at each of the four corners of the upper surface of the base 301. The upper end of the telescopic column 305 is screwed to the outer cylinder 201. By setting the secondary lifting assembly at the four corners of the base plate 206, the outer cylinder 201 can be lifted more stably. The outer cylinder 201 is lifted by the extension and retraction of the telescopic column 305.

[0032] In this embodiment, a connecting plate 307 is fixed to one side of the telescopic column 305. The connecting plate 307 is screwed to the output end of the hydraulic push rod 306. A conduit 308 is connected to one side of the hydraulic push rod 306. The hydraulic push rod 306 is connected to the telescopic column 305 through the connecting plate 307. The telescopic column 305 is extended and retracted by the extension and retraction of the hydraulic push rod 306 to achieve lifting. The telescopic column 305 is designed with increasing dimensions from the inside to the outside to facilitate the extension and retraction of the telescopic column 305. The hydraulic cylinder of the hydraulic push rod 306 can be connected to external hydraulic oil through the conduit 308 to replenish the hydraulic oil.

[0033] In this embodiment, two drive motors 302 are screwed to the inner side of the movable base 30. The two drive motors 302 are symmetrically arranged. The output end of the drive motor 302 is connected to the drive wheel 303 for transmission. The driven wheel 304 is rotatably connected to the base 301. The drive motor 302 controls the rotation of the drive wheel 303. While the drive wheel 303 drives the base 301 to move, the driven wheel 304 moves along with it. The driven wheel 304 is installed on the base 301 by bolts.

[0034] In this embodiment, the motor 208 is screwed to the outer cylinder 201, and the output end of the motor 208 is driven to the lead screw 209. A connecting block 2010 is provided between the motor 208 and the moving frame 203. The lead screw 209 passes through the connecting block 2010 and is threaded to it. The connecting block 2010 is screwed to the moving frame 203. The motor 208 controls the lead screw 209 to rotate. Based on the action of the screw, the connecting block 2010 on the lead screw 209 performs linear movement, that is, vertical displacement, which drives the moving block connected to the connecting block 2010 to move together, so that the operating table 10 on the front support frame 207 of the moving frame 203 moves together.

[0035] In this embodiment, the support frame 207 is designed in an "L" shape. The support frame 207 is connected to the movable frame 203 and the operating table 10 by screws. The inner side of the movable frame 203 is provided with a guide wheel 204, and the outer side of the outer cylinder 201 is provided with a guide rail 202 adapted to the guide wheel 204. When the movable frame 203 moves, the guide wheel 204 moves synchronously outside the guide rail 202. Rubber pads are fixed on the surfaces of the guide rail 202 and the guide wheel 204. The rubber pads stabilize the movement of the guide wheel 204 on the guide rail 202 and prevent slippage.

[0036] In this embodiment, a stop 205 is provided at the upper end of the guide rail 202. The stop 205 has a "T" shaped cross section and is made of rubber. The stop 205 blocks the moving frame 203 to prevent the moving frame 203 from moving beyond the guide rail 202, thus restricting the movement of the moving frame 203.

[0037] Specifically, before use, ensure that the operating platform is in its initial state, that is, the lifting component 20 and the secondary lifting component are in their lowest positions, the hydraulic push rod 306 and the telescopic column 305 are fully retracted, the motor 208 and the drive motor 302 are in a de-energized state, ensure that the operating platform 10 is firmly connected to the moving frame 203 through the support frame 207, configure the remote control to start the drive motor 302, and move the moving base 30 to the target position through the cooperation of the drive wheel 303 and the driven wheel 304;

[0038] After the mobile base 300 is in place, the drive motor 302 is turned off and the motor 208 is started. The motor 208 controls the lead screw 209 to rotate, which drives the connecting block 2010 and the moving frame 203 to move up and down synchronously. At the same time, the moving frame 203 ensures the stability of the movement process through the cooperation of the guide wheel 204 and the guide rail 202. When the moving frame 203 reaches the required height, the motor 208 is turned off and the steel structure welding operation is carried out on the operating table 10. When the mobile base 30 is moving, there should be no personnel on the operating table 10. The drive wheel 303 and the driven wheel 304 are tires used for movement. Their tire pressure and the wheel hubs used must be sufficient to support the structure above to ensure that the mobile base 30 can move normally and avoid the structure above being too heavy, which would prevent it from moving.

[0039] Considering that the length of the lead screw 209 is fixed, a secondary lifting device is set between the movable base 30 and the lifting assembly 20 to allow for secondary adjustment of the height of the operating platform 10. By activating the hydraulic push rod 306, the hydraulic push rod 306 extends and retracts, driving the outer cylinder 201 on the telescopic column 305 to rise and fall. The extension height of the telescopic column 305 is adjusted according to actual needs to ensure that the outer cylinder 201 reaches the required height.

[0040] like Figure 6-7 As shown, considering that the size of the steel structure to be welded is not fixed, two lifting components 20, a movable base 30 and a secondary lifting component can be set under one operating platform 10, or two operating platforms 10 can be set, with one lifting component 20, a movable base 30 and a secondary lifting component set under each operating platform 10. The two operating platforms 10 can be temporarily fixed to accommodate larger steel structures and improve adaptability.

[0041] It should be noted that when a single lifting component 20 is installed under the operating table 10, the size of the support frame 207 needs to be consistent with the length of the operating table 10 to ensure that the support frame 207 can stably support the operating table 10. When two lifting components 20 are installed, the size of the two support frames 207 also needs to be compatible with the operating table 10.

[0042] It is worth noting that the control method in this application is through a remote control. The control circuit of the remote control can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. Therefore, this application will not explain the control method and circuit connection in detail.

[0043] The components of this utility model, such as the operating table 10, outer cylinder 201, guide rail 202, moving frame 203, guide wheel 204, stop block 205, base plate 206, support frame 207, motor 208, lead screw 209, connecting block 2010, base 301, drive motor 302, driving wheel 303, driven wheel 304, telescopic column 305, hydraulic push rod 306, connecting plate 307, and conduit 308, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of those features.

[0046] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components.
