Problems solved by technology
For the overturning operation of super-large diameter penstock steel pipes, steel wire ropes and snap rings are generally used to form movable sleeves to tighten the steel pipe steel wall, and one end of the penstock steel pipes is hoisted to a certain height through the cooperation of hoisting equipment and steel wire ropes to form a turning operation. In the process of turning over the steel pipe, it is easy to cause deformation and out-of-round of the penstock steel pipe, which will affect the installation operation of the penstock

Embodiment Construction
[0026] Such as Figure 1~3 Among them, a super-large-diameter pressure steel pipe turning device includes turning lugs 1, upper support beams 2, main beams 5, support seats 7 and lower support beams 8. The turning lugs 1 are installed on the upper end of the main beam 5, and the upper The support beam 2 is vertically installed on the main beam 5, the lower end of the main beam 5 is connected to the support base 7, the lower support beam 8 is symmetrically installed on the support base 7, the lower support beam 8 is parallel to the upper support beam 2, and the free end of the upper support beam 2 The hook 3 is installed, and the installation side of the main beam 5 relative to the upper support beam 2 is provided with lifting lugs 9 .
[0027] The support seat 7 can be set as a triangle. When the penstock 11 turns over, the contact part between the support seat 2 and the bottom surface forms a fulcrum, which is convenient for the penstock 11 to turn over.
[0028] The turning...

The invention provides a super-large diameter pressure steel pipe turning-over device and turning-over method. The super-large diameter pressure steel pipe turning-over device comprises a turning-over lifting lug, an upper support beam, a main beam, a support seat and lower support beams. The turning-over lifting lug is installed at the upper end of the main beam. The upper support beam is perpendicularly installed on the main beam. The lower end of the main beam is connected with the support seat. The lower support beams are installed on the support seat symmetrically and are parallel to the upper support beam. A clamping hook is installed at the free end of the upper support beam. A hoisting-conveying lifting lug is arranged on the installation side, relative to the upper support beam, of the main beam. Through three-point locating of the upper support beam and the two lower support beams, the effect that deformation does not occur to a pressure steel pipe in the turning-over process is ensured, and the out-of-round condition is prevented. According to the super-large diameter pressure steel pipe turning-over device, in the hoisting process, the clamping hook achieves automatic locking along with inclining of the pressure steel pipe, high altitude operation of personnel is avoided, and safety of turning-over operation of the pressure steel pipe is improved.
Description
technical field [0001] The invention relates to the field of fabrication and installation of super-large-diameter steel pipes, in particular to a turning device and method for super-large-diameter pressure steel pipes. Background technique [0002] In the production and installation of super-large-diameter penstocks in hydropower stations, it is more convenient to form super-large-diameter penstocks by welding them in circles on a special platform with multi-resolution tiles. After the penstock is assembled, the penstock is placed vertically on the circle platform, and the super-large-diameter penstock cannot meet the vertical transportation requirements due to its large diameter. Therefore, the super-large-diameter penstock needs to be turned over before it can be transported. For the overturning operation of super-large-diameter pressure steel pipes, steel wire ropes and snap rings are generally used to form movable sleeves to tighten the steel pipe steel walls, and one en...
