This invention relates to the field of intelligent armored door technology, specifically to door core welding equipment and processes for fireproof and soundproof intelligent armored doors. The equipment includes a production line base, with a door processing production line fixedly connected to the top of the base. A door core welding angle adjustment mechanism is fixedly connected to the front of the base, and a door core welding platform is located on the front of the adjustment mechanism. By incorporating the production line base, door processing production line, door core welding angle adjustment mechanism, and door core welding platform, this invention achieves automated and precise operation of the door core welding process, significantly improving the welding efficiency and quality of the fireproof and soundproof intelligent armored door core. Through the coordinated action of each component, the armored door can be quickly and stably fixed and its angle adjusted, creating favorable conditions for welding. Throughout the process, various electric push rods, rotating rods, sliding plates, and other components cooperate to achieve precise motion control.

The invention provides a steel structure installation operation platform and a control method. According to the operation platform, a steel column is arranged in the height direction of a to-be-installed steel structure, and a magnet fixing body extending in the axial direction is arranged in the column body. And the platform body is arranged on the steel column in a sleeving manner and is provided with a holding mechanism which can be controlled to hold or loosen the steel column. A fixed part of the mechanical slow descending device is fixedly connected above the platform body, a movable part of the mechanical slow descending device acts on the steel column, and constant resistance is provided when the platform body descends relative to the steel column. And the electromagnetic speed control device is mounted on the platform body, comprises an electromagnet and can be controlled to generate variable magnetic force acting on the fixed magnet. The wind speed sensor and the laser sensor are fixedly installed on the platform body and are in communication connection with the electromagnetic speed control device; the electromagnetic speed control device adjusts the variable magnetic force according to the wind speed value and the height value, and the descending speed of the platform body is controlled. By means of the operation platform, the installation work of the steel structure can be more efficient and safer.

The utility model relates to the technical field of pressure vessel machining, and discloses an annular inlet welding device for pressure vessel machining, which comprises a base and moving wheels, the moving wheels are fixedly mounted at four corners of the bottom end of the base, the top end of the base is fixedly connected with a supporting seat, a driving motor is fixedly mounted on the right side of the supporting seat, and the driving motor is fixedly connected with the base. And the output end of the driving motor penetrates through the interior of the supporting seat and is fixedly connected with a fixed seat. According to the annular inlet welding device for pressure vessel machining, by arranging parts such as a driving motor, according to the diameter of an annular inlet, an adjusting shaft can be screwed, a movable base can be driven to move downwards, when a welding head is adjusted to the welding position, the welding head stops, the driving motor is started, and a fixed base is driven to rotate; and at the moment, the connecting block on one side of the fixing base can rotate in the annular groove in a guiding mode, so that the annular inlet is accurately welded conveniently, and the problem that the position of the welding head is inconvenient to adjust according to the diameter of the annular inlet is solved.
