Description

Technical Field

[0001] This utility model relates to the field of pressure vessel cylinder and head installation technology, specifically to an auxiliary device for assembling and installing pressure vessel cylinder and head. Background Technology

[0002] In the pressure vessel manufacturing process, the assembly of the head and the shell is usually carried out by lifting the head with hoisting machinery and then assembling it manually. This process not only requires a long time to occupy the hoisting machinery, but also is time-consuming and the assembly quality is difficult to guarantee. The assembly of the head and the shell is very similar to the assembly of the flange and the shell. In the patent with patent authorization number CN222002284 U, the device can be used for the assembly of the head and the shell, but its locking mechanism cannot be used to fix the head, so it is inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for assembling and installing a pressure vessel cylinder and a head, comprising a support platform, wherein the upper surface of the support platform is uniformly provided with sliding tracks, and there are no fewer than three sets of sliding tracks, which are evenly arranged around the center of the support platform. Each set of sliding tracks is provided with a sliding positioning component that is slidably connected. The support platform is provided with a plurality of three up-and-down adjusting components, and a central support plate is fixed to the upper end of the three up-and-down adjusting components. The center of the support platform is connected to a drive shaft through a bearing. A central positioning transmission component that drives the sliding positioning components to move is connected to the outer side of the drive shaft. An up-and-down adjusting transmission component that drives the up-and-down adjusting components is connected to the outer side of the upper end of the drive shaft.

[0005] Furthermore, the sliding positioning component includes a sliding seat, the lower end of which is a boss-shaped structure, and a set of two sliding tracks, each with an inverted L-shaped cross-section. The two sliding tracks in a set form a concave structure, thus matching the lower end of the sliding seat. A central positioning claw is fixed on the upper surface of the sliding seat. Moving the sliding seat can drive the central positioning claw to move, and moving the central positioning claw can position the end cap to the center position.

[0006] Furthermore, the central positioning transmission component includes screws uniformly fixed to the upper surface of the support platform via bearing seats. Each screw corresponds to a sliding positioning component, and the screws are connected to the corresponding sliding seats via threaded connections. A bevel gear is fixed to the outer side of the drive shaft, and a second bevel gear is fixed to one end of each screw. Each second bevel gear meshes with the bevel gear. When the drive shaft rotates, it can drive the bevel gears to rotate. The rotation of the bevel gears can drive all the second bevel gears to rotate. The rotation of the second bevel gears can drive the screws to rotate. The rotation of the screws can drive the sliding positioning components to move.

[0007] Furthermore, the upper and lower adjustment component includes a connecting pipe connected by a bearing connection. Each connecting pipe is internally connected to a screw rod by a threaded connection. When the connecting pipe rotates, it can drive the screw rod to move up and down. The screw rod can drive the central support plate to move up and down, thereby adjusting the upper and lower height of the end cap workpiece.

[0008] Furthermore, the up-and-down adjustment transmission component includes a gear one fixed on the drive shaft, and a gear two is provided on the outside of each connecting pipe. Each gear two meshes with gear one. When the drive shaft rotates, it can drive gear one to rotate, which in turn drives gear two to rotate, and the rotation of gear two can drive the connecting pipe to rotate.
