Problems solved by technology
The existing penstock transport flat trolley in the cave is usually welded or bolted on the trolley to match the fixed bracket of the penstock. support, and finally adjust and reinforce the pressure steel pipe, this method is time-consuming and laborious, and the center of gravity of the pressure steel pipe is unstable during the adjustment process, which is likely to cause safety accidents. In order to solve the problems of centering and stability, the present invention proposes an automatic centering adjustment The device and method can realize the automatic micro-alignment of the steel pipe at the station in the hole

Embodiment Construction
[0024] Such as Figure 1-2 As shown, a penstock installation and adjustment bracket device for a hydropower station includes a support base 1, a curved beam 2, a roller 3, a roller block 4 and a bearing bush 5, and a hemispherical groove is opened under the support base for matching with The ball head support assembly on the jacking mechanism of the flatbed trolley serves as the main bearing point; Figure 3-6 As shown, the curved beam includes an end plate 2-1, a front and rear wing plate 2-2, a web 2-3, a middle wing plate 2-4, a supporting base limiting plate 2-5, and a supporting base connecting plate 2-6 , Ribs 2-7, the entire curved beam is a weldment (simple manufacture). The front and rear wing plates and the middle wing plate are provided with open slots for installing rollers, and the roller block is fixedly connected with each wing plate through bolts (or screws) to limit the falling of the rollers. The support base limit plate and There are bolt holes on the conn...

The invention relates to a hydropower station pressure steel pipe installation adjustment bracket device and method. The device comprises supporting bases, bent beams, rollers, roller clamping blocks and bearing bushes. Semi-spherical grooves are formed in the lower portions of the supporting bases and serve as matched connection devices of the bent beams and a flat plate trolley ejecting and lifting mechanism. Opening grooves are reasonably distributed in the bent beams. The rollers are placed in the opening grooves. Falling of the rollers is limited through the roller clamping blocks and bent beam bolts. The bearing bushes are placed on the rollers and used for rolling adjustment of pressure steel pipes. Through the cooperation with the actions of ejecting and lifting oil cylinders, the pressure steel pipes can be rapidly adjusted and ejected and lifted to be installed. The hydropower station pressure steel pipe installation adjustment bracket device is simple in structure and convenient to manufacture.
Description
technical field [0001] The present invention relates to a penstock transportation and installation device and method for a large-scale hydropower station, in particular to a method for adjusting the center of gravity of a penstock that needs to be installed and used during the penstock installation, and at the same time, a set of penstocks that can be connected with the inside of the cave is designed according to requirements. The transport trolley cooperates with the bracket device for adjusting the center of gravity of the penstock. Background technique [0002] When the penstocks used in the pouring construction of hydropower tunnels are transported and transported for the second time, the penstock transport flat trolley and a large lifting equipment are mainly used in China at present. The existing penstock transport flat trolley in the cave is usually welded or bolted on the trolley to match the fixed bracket of the penstock. support, and finally adjust and reinforce t...
