Description

Technical Field

[0001] The utility model relates to the technical field of bottom rotary structures, in particular to a bottom rotary structure of a large steel structure welding platform. Background Art

[0002] When welding a workpiece, it is generally placed on a welding rotary platform for welding. The welding rotary platform makes it convenient for the welder to rotate the workpiece and adjust the welding position of the workpiece.

[0003] According to Chinese patent CN 217618560 U, a welding rotary platform with an adjustment function is disclosed, which relates to the technical field of welding rotary platforms, including a fixed seat, a rotary seat is fixedly connected to the top of the fixed seat, a rotary tube is movably connected to the top of the rotary seat, an adjustment tube is movably connected to the top of the rotary tube, an operating table is fixedly connected to the top of the adjustment tube, a lifting tube is fixedly connected to the top of the operating table, and a fixed spring is arranged on the surface of the lifting tube. By arranging a reinforcement plate and a moving tube, when in use, the height position of the moving tube needs to be adjusted up and down, thereby adjusting the height of the welding box, and then the workpiece is fixed by using the reinforcement plate. During the processing, the operator can rotate the operating table to drive the adjusting tube to rotate on the top of the rotating tube, thereby adjusting the position of the workpiece during welding. Therefore, when the welding rotary platform is in use, the welding height can be adjusted, which is convenient for welders of different heights to use;

[0004] Although this patent can achieve the effect of being convenient for welders of different heights to use by setting a lifting tube, since the welding box is manually rotated during the welding process, this may cause too much or too little rotation during the rotation process, and the rotation distance needs to be adjusted again. The operation is more cumbersome and reduces the welding efficiency.

[0005] Therefore, it is necessary to provide a new bottom rotation structure of a large steel structure welding platform to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a bottom rotary structure of a large steel structure welding platform.

[0007] The utility model provides a bottom rotating structure of a large steel structure welding platform, comprising a base, a rotating mechanism for rotating the welding platform is installed on the top of the base, and the rotating mechanism comprises:

[0008] A slewing assembly is installed on the top of the base, comprising a support plate fixed on the top of the base, the inner side of the support plate is rotatably connected with a slewing column through a bearing, the outer wall of the slewing column is installed with a driving assembly for driving the slewing column to rotate, a welding table is fixed on the top of the driving assembly, a plurality of slide grooves are equidistantly provided at the bottom of the welding table, one end of the slewing column is slidably connected to the inner side of the slide groove, a plurality of arc blocks are equidistantly fixed at the bottom of the welding table, and the other end of the slewing column is slidably connected to the outer wall of the arc block;

[0009] The welding assembly is installed on the top of the welding table and is used to weld the workpiece.

[0010] Preferably, the driving assembly includes a groove opened on the top of the base, a motor is fixed on the inner side of the groove, a rotating rod is fixed on the output end of the motor, a driving gear is fixed on the outer wall of the rotating rod, a driven gear is fixed on the outer wall of the rotating column, the driven gear is meshed and connected with the driving gear, and the rotating rod is rotatably connected to the bottom of the welding table through a bearing.

[0011] Preferably, the welding assembly comprises four welding boxes equidistantly mounted on the welding table.

[0012] Preferably, two shock-absorbing pads are symmetrically fixed to the bottom of the base.

[0013] Preferably, four of the slide grooves and four of the arc-shaped blocks are provided.

[0014] Preferably, the motor is a three-phase asynchronous motor.

[0015] Compared with the related art, the bottom rotary structure of the large steel structure welding platform provided by the utility model has the following beneficial effects:

[0016] Since the operating table is rotated manually during the welding process, this may result in excessive or insufficient rotation, which requires further adjustment of the rotation distance. The rotating mechanism can automatically rotate the welding table through the rotating column without manual rotation, thus avoiding excessive or insufficient rotation. This not only simplifies the operation but also improves the welding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
