Description

Technical Field

[0001] The utility model belongs to the technical field of pressure steel pipe manufacturing, and particularly relates to an auxiliary device for welding a pressure steel pipe and a stiffening ring. Background Art

[0002] With the modernization of society, buildings have become taller and larger, which will increase the requirements for hydropower. The manufacture of large-diameter pressure steel pipes has always been an important part of hydropower projects. The wall thickness of large-diameter pressure steel pipes is relatively thin. In order to enhance its rigidity and strength, it is often necessary to install steel rings around the pipe body, which are called stiffening rings. Welding stiffening rings can make the cross-sectional shape of the steel pipe more regular, reduce deformation when subjected to external forces, thereby increasing its rigidity and strength. Large-diameter pressure steel pipes usually bear greater pressure. Welding stiffening rings can make the steel pipe distribute pressure more evenly when under pressure, thereby improving its pressure resistance. At the same time, welding stiffening rings can reduce the deformation of the steel pipe when subjected to external forces, thereby improving its stability. Therefore, the assembly quality of stiffening rings and pressure steel pipes is particularly important.

[0003] The traditional process for assembling stiffeners to penstocks involves first marking the stiffener assembly line on the penstock, then welding a saddle plate to the penstock wall, and finally using a wedge plate to bring the stiffener and penstock together. However, after welding, the saddle plate must be cut and the welded area polished, resulting in inefficient assembly of the penstock and stiffener. Utility Model Content

[0048] ; Embodiment:

[0049] This embodiment provides an auxiliary device for welding a penstock and a stiffening ring, which is used to solve the technical problem of the low assembly efficiency of the penstock and the stiffening ring in the prior art. The auxiliary device for welding the penstock and the stiffening ring includes a frame body 1, a moving component, a driving component 3, a guiding component and a jack 5, wherein:

[0050] The frame body 1 is in a C shape, and the frame body 1 is a structural member made of steel.

[0051] The moving assembly is installed at the bottom end of the frame 1. In this way, the frame 1 can be easily moved by the arrangement of the moving assembly.

[0052] One end of the driving component 3 can be detachably mounted on the frame 1. In the working state, the other end of the driving component 3 is attached to the pressure steel pipe tile to which the stiffening ring is to be welded. The driving component 3 is used to drive the moving component to move. In this way, driving the driving component 3 causes the driving component 3 to move on the side wall of the pressure steel pipe, driving the frame 1 connected to the driving component 3 to move synchronously.

[0053] The guide assembly 4 is installed on the frame 1. The guide assembly 4 is used to guide the moving assembly. Through the setting of the guide assembly 4, the moving assembly moves along the arrangement direction of the pressure steel pipe, and at the same time, the driving assembly 3 and the side wall of the pressure steel pipe are always in contact during the movement.

[0054] The fixed end of the jack 5 can be detachably mounted on the frame 1, and the jack 5 is arranged opposite to the drive assembly 3. The jack 5 is used to tighten the stiffening ring to be welded. By installing the jack 5 on the frame 1, when the frame 1 moves, the jack 5 moves synchronously, and through the setting of the jack 5, the stiffening ring to be welded is tightened on the pressure steel pipe, which facilitates the assembly of the stiffening ring and the pressure steel pipe. In this way, there is no need to weld the horse plate, which saves time and effort, thereby improving the welding efficiency of the stiffening ring and the pressure steel pipe.

[0055] Through the above structure, when using the auxiliary device for welding the pressure steel pipe and the stiffening ring provided by the utility model, the pressure steel pipe tile is first placed vertically on a plane, and then the auxiliary device is hung on both sides of the pressure steel pipe tile of the stiffening ring to be welded, so that the pressure steel pipe tile is located in the middle of the frame 1, and the other end of the driving component 3 is attached to the side wall of the pressure steel pipe tile of the stiffening ring to be welded, and at the same time, the guide component 4 is connected to the top of the pressure steel pipe tile of the stiffening ring to be welded, and then the stiffening ring assembly line is drawn, and then the moving component is driven by the driving component 3 to move until the jack 5 is moved to the position of the stiffening ring to be assembled, and the setting of the guide component 4 enables the auxiliary device to move along the arrangement direction of the pressure steel pipe tile of the stiffening ring to be welded, avoiding it from moving. The jack 5 is then driven to fit the wall of the penstock and finally welded to fix it. The jack 5 is arranged relative to the driving component 3, and the other end of the driving component 3 is in contact with the side wall of the penstock, so that the force on the penstock and the stiffening ring is more uniform and can fit better. Then the driving component 3 is used to drive the moving component to move in the arrangement direction of the penstock tiles until it moves to the position of the next stiffening ring to be assembled. Then, the above process is repeated until the assembly of all stiffening rings is completed. Therefore, through the cooperation of the driving component 3 and the jack 5, the assembly of the stiffening ring and the penstock can be achieved without welding the horse plate, thereby improving the assembly efficiency of the stiffening ring and the penstock.

[0073] Both ends of the connecting rod 42 are respectively mounted on the outer side walls of the two second sleeves 41 .
