Description
Technical Field
[0001] The utility model belongs to the technical field of pressure vessels, and in particular relates to a welding butt joint device for pressure vessels. Background Art
[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. Pressure vessels are widely used. They play an important role in many departments such as industry, civil industry, military industry, and many fields of scientific research. At present, pressure vessels need to use special pressure vessel welding and docking devices to operate during production.

[0004] Although the pressure vessels can be docked, there are still some problems in daily use. First, before docking, the two pressure vessels need to be placed between the arc-shaped clamps on both sides respectively, and the pressure vessels are not convenient to place horizontally, which increases the ineffective working hours of relevant staff and the labor burden of relevant staff. When the pressure vessel is placed for clamping, its docking end will tilt downward due to gravity, which causes the two pressure vessels to be skewed at the docking point when docking. Finally, during welding, due to the lack of support at the docking point, the welding point will be directly subjected to force, which will lead to quality problems in the later stage. Utility Model Content
[0005] In view of this, the utility model provides a pressure vessel welding and docking device, which can greatly reduce the ineffective working hours of relevant staff through the docking mechanism, reduce the labor burden of relevant staff, and can also level the docking end while clamping the pressure vessel, thereby ensuring that the docking parts of the pressure vessel are overlapped and aligned, solving the problem of direct force on the welding part due to lack of support at the docking part during welding.
[0006] In order to solve the above technical problems, the utility model provides a pressure vessel welding docking device, including a base plate and a docking mechanism arranged in the middle of the rear end of the upper surface of the base plate, the docking mechanism includes a vertical guide rail arranged in the middle of the rear end of the upper surface of the base plate, a transverse guide rail is slidably connected in the vertical guide rail, a laterally symmetrically distributed movable plate is slidably connected in the transverse guide rail, a plug-in plate is movably plugged into the slot arranged on the inner end of the front end of the movable plate, arc-shaped docking plates are arranged at the upper and lower ends of the inner side surface of the plug-in plate, an extension component is arranged in the plug-in plate, and a driving component is also arranged at the front end of the base plate.
[0007] The docking mechanism also includes a bidirectional screw rod rotatably connected to the transverse guide rail, the left and right ends of the bidirectional screw rod are respectively threadedly connected to the screw holes corresponding to the rear end of the movable plate adjacent to the same side, and a motor 1 is provided on the right surface of the transverse guide rail, the left end of the output shaft of the motor 1 is fixedly connected to the right extension end of the bidirectional screw rod, and the motor 1 is electrically connected to the external single-chip computer; the docking mechanism also includes an electric telescopic rod arranged on the bottom wall of the vertical guide rail, the upper end of the telescopic end of the electric telescopic rod is fixedly connected to the rear end of the lower surface of the transverse guide rail, and the electric telescopic rod is electrically connected to the external single-chip computer.
[0008] The extension assembly includes extension plates that are slidably connected to the rectangular grooves on the upper surface of the plug-in board; the extension assembly also includes screw barrels that are respectively arranged on the bottom wall of the rectangular grooves.

[0010] The driving component includes a rotating circular plate rotatably connected to the front end of the upper surface of the base plate, and a motor 2 is provided at the front end of the lower surface of the base plate. The upper end of the output shaft of the motor 2 is fixedly connected to the lower extension end of the rotating circular plate, and the motor 2 is electrically connected to the external single-chip computer.
[0011] The beneficial effects of the above technical solution of the utility model are as follows:
[0012] 1. First, the relevant staff replaces the corresponding arc-shaped docking plate according to the diameter of the pressure vessel to be welded. When replacing the arc-shaped docking plate, it is only necessary to pull it upward out of the slot, and then movably connect the corresponding arc-shaped docking plate to the slot to complete the replacement. After that, the relevant staff places the lower half of the pressure vessel to be welded on the middle of the upper end surface of the rotating circular plate, and then the relevant staff controls the operation of motor one through an external single-chip microcomputer. The rotation of the motor one output shaft drives the bidirectional lead screw to rotate synchronously. While rotating, the bidirectional lead screw drives the two moving plates, the plug-in plate and the arc-shaped docking plate to move synchronously along the transverse guide rail, thereby pushing the lower half of the pressure vessel to move until the axis of the lower half of the pressure vessel coincides with the axis of the rotating circular plate, and then the relevant staff controls the motor one to operate in the reverse direction through the external single-chip microcomputer, and the various mechanisms are reset.

The relevant staff controls the electric telescopic rod to stop operating through the external single-chip computer, and at the same time controls the operation of motor one. The rotation of the output shaft of motor one drives the bidirectional lead screw to rotate synchronously. While the bidirectional lead screw rotates, it drives the two moving plates, the plug-in plate and the arc docking plate to move synchronously and centripetally along the transverse guide rail, so as to push the upper part of the pressure vessel to move. It is only necessary to stack the docking points of the two pressure vessels relative to each other, which greatly reduces the ineffective working hours of the relevant staff and reduces the labor burden of the relevant staff. The docking end of the pressure vessel can also be leveled while clamping the pressure vessel, thereby ensuring that the docking points of the pressure vessel overlap and align, solving the problem of direct force on the welding point due to lack of support at the docking point during welding.
[0013] 2. Turn the operating lever in sequence according to the height of the upper part of the pressure vessel. The rotation of the operating lever drives the corresponding extension plate to move up along the rectangular notch, thereby ensuring the safety of the upper part of the pressure vessel during movement.
[0014] 3. Perform electric welding on the joints of the pressure vessel. After the spot welding is completed, the relevant staff will control the operation of Motor 2 through an external single-chip microcomputer. The output shaft of Motor 2 will rotate to drive the rotating circular plate and the pressure vessel to rotate synchronously, so that the relevant staff can perform fast welding.

[0025] The working principle of a pressure vessel welding and docking device provided by the utility model is as follows: first, the relevant staff replaces the corresponding arc-shaped docking plate 204 according to the diameter of the pressure vessel to be welded. When replacing the arc-shaped docking plate 204, it is only necessary to pull it upward out of the slot, and then movably connect the corresponding arc-shaped docking plate 204 with the slot to complete the replacement. After that, the relevant staff places the lower half of the pressure vessel to be welded on the middle of the upper end surface of the rotating circular plate 500, and then the relevant staff controls the operation of the motor 1 206 through the external single-chip microcomputer. The rotation of the output shaft of the motor 1 206 drives the bidirectional screw rod 205 to rotate synchronously, and the bidirectional screw rod 205 drives the two movable plates while rotating. 202, the plug-in board 203 and the arc-shaped docking plate 204 move synchronously centripetally along the transverse guide rail 201, thereby pushing the lower half of the pressure vessel to move until the axis of the lower half of the pressure vessel coincides with the axis of the rotating circular plate 500, and then the relevant staff controls the motor 206 to operate in the reverse direction through the external single-chip microcomputer, and each mechanism is reset. After that, the relevant staff places the upper half of the pressure vessel to be welded on the upper end surface of the lower half of the pressure vessel through the external crane, and then the relevant staff controls the operation of the electric telescopic rod 207 through the external single-chip microcomputer, and the telescopic end of the electric telescopic rod 207 moves upward to drive the transverse guide rail 201 and its auxiliary mechanisms to move upward along the vertical guide rail 200 until the pressure vessel After the docking point between the upper part of the pressure vessel and the lower part of the pressure vessel is located between the two vertically adjacent arc-shaped docking plates 204, the relevant staff controls the electric telescopic rod 207 to stop operating through the external single-chip computer, and simultaneously controls the operation of the motor 1 206. The output shaft of the motor 1 206 rotates to drive the bidirectional screw rod 205 to rotate synchronously. While the bidirectional screw rod 205 rotates, it drives the two moving plates 202, the plug-in plate 203 and the arc-shaped docking plate 204 to move synchronously along the transverse guide rail 201, thereby pushing the upper part of the pressure vessel to move. It is only necessary to stack the docking points of the two pressure vessels relative to each other, which greatly reduces the ineffective working hours of the relevant staff and reduces the labor burden of the relevant staff. While clamping the pressure vessel, the butt end can also be leveled to ensure that the butt joints of the pressure vessel are aligned and overlapped, solving the problem of direct force on the welding joints due to lack of support at the butt joints during welding. Then, the operating rod 302 is turned in sequence according to the height of the upper part of the pressure vessel. The rotation of the operating rod 302 drives the corresponding extension plate 300 to move up along the rectangular notch to ensure the safety of the upper part of the pressure vessel during movement. Then, the butt joints of the pressure vessel are welded. After spot welding is completed, the relevant staff controls the operation of motor 2 501 through an external single-chip microcomputer. The output shaft of motor 2 501 rotates to drive the rotating circular plate 500 and the pressure vessel to rotate synchronously, so that the relevant staff can perform fast welding.
