Embodiment
As shown in figs 1-9, a kind of transport of pressure steel pipe of hydropower station and mounting and adjusting bracket system, including bracket, be arranged on
B hydraulic systems and the A hydraulic systems being arranged in hole on dollie outside hole, the A hydraulic systems are including all around
A1 hydraulic cylinders, A2 hydraulic cylinders, A3 hydraulic cylinders and the A4 hydraulic cylinders being arranged side by side, B hydraulic systems include all around being arranged side by side
B1 hydraulic cylinders, B2 hydraulic cylinders, B3 hydraulic cylinders and B4 hydraulic cylinders；When A hydraulic systems overlap with B hydraulic systems in center,
Each Position of Hydraulic Cylinder of two hydraulic systems is misaligned, so in docking, will not cause conflict, can smoothly dock.
The bracket includes support base 1, camber beam 2, roller bearing 3, roller bearing fixture block 4, bearing shell 5, connecting pin 6 and movable supporting 7.
The camber beam 2 is provided with open slot 201, and open slot 201 is used to install roller bearing 3, and roller bearing fixture block 4 is fixed with camber beam 2 to limit rolling
Axle 3 comes off.
Due to lay travelling bogie rail in hole, and wanted transport vehicle outside hole, therefore, it is generally the case that B hydraulic systems
Be arranged on underground, hydraulic system infrastructure top is almost concordant with ground outside hole, completes in advance, without when, or mistake
Pinch in is wanted during car, it is almost concordant with ground, a little can be higher by, did not influenceed car.And need the penstock transported
A diameter of 6000mm, long 12000mm, weigh 80 tons.And B hydraulic systems are in the case of unmodified, during work, the flexible height of highest
It is bigger due to lifting load close to 1000mm, and hydraulic cylinder travel is larger in B hydraulic systems, so, when not only resulting in work
Destabilizing factor increase, and cost can also greatly improve.
In order to reduce the top lifting height of B hydraulic systems, it is provided with camber beam 2 between the installation site of two support base of one end 1
Flat segments, flat segments are connected by the changeover portion and the segmental arc of rear end tilted down.So directly reduce the top of hydraulic system
Rise, 300mm~400mm can be reduced by the design, be operated so as to which stability and low cost be effectively ensured.Due to traditional
Bracket section, in order to ensure the support of bearing shell 5, limiting plate 203 and reinforcement 202 are provided with the end of camber beam 2, to install connecting pin
6 and movable supporting 7；Bearing shell 5 is placed on roller bearing 3, fore-end quilt when can slide, while work along the rotation direction of roller bearing 3
Movable supporting 7 supports.Before B hydraulic systems prepare jacking undertaking, movable supporting 7 is rotated at limiting plate 203, adjusts bearing shell 5
Position, then B hydraulic systems jacking accept；After the completion of the docking jacking of A hydraulic systems, movable supporting 7 is rotated, away from work
Make position, do not influence the center of gravity regulation of later stage steel pipe.
A kind of pressure steel pipe of hydropower station transport and mounting and adjusting bracket system application method：
Penstock is transported to outside hole behind precalculated position, and rotary moveable is supported at limiting plate, adjusts bearing shell position, is led to
Four hydraulic cylinders synchronization of jacking up simultaneously of the B hydraulic systems pre-set outside hole is crossed, penstock is jacked up by bracket, transported
Defeated vehicle leaves, and transport flat panel dolly drives to precalculated position, four hydraulic cylinders synchronization of jacking up pair simultaneously of A hydraulic systems in hole
Connect, then transport into hole, the top lifting height by slowly adjusting hydraulic cylinder A1-A4, which adjusts penstock position of centre of gravity, is pacified
Dress.
This patent is the improvement carried out on the patent of Application No. " 201621068274.5 ", and the inside and outside docking in its hole is transported
The advantage of centre of gravity adjustment in defeated and hole, with reference to above-mentioned patent, is not just repeated one by one herein.
Large lifting equipment can be saved by above method, steady docking transport in hole outside penstock hole is completed, pacify
It is complete reliable, and cost is relatively low.
