Description
Technical field
The utility model belongs to the big part large-scale substation transformer installing area of electric power, and in particular to high-power transformer is shifted
Combination rail slideway.
Background technology
The propulsion of sturdy power grid theory is built with State Grid Corporation of China, extra high voltage line builds like a raging fire, supporting
Ultra-high voltage transformer station is constantly constructed and put into operation.After the supporting high-power transformer of ultra-high voltage transformer station is transported to station, displacement work in place
Be smoothed out, direct relation equipment safety, the progress of power transformation installation.
The matching used volume of transformer of voltage class 500kV above transformer station, weight are very big, its individual event split transport
Weight all reaches more than 130 tons, and the matching used volume of transformer of ultra-high voltage transformer station, weight are bigger.Either direct current or friendship
Stream, the hauled weight of its individual event split is all up to more than 300 tons.
Influenceed by substation field environment and installation financial cost, high-power transformer is difficult to take lifting mode to install just
Position, takes hydraulic pushing sliding method to carry out installing in place more at present.The method carries out high-power transformer shift operation, mainly leads to
Cross and roll, lay steel plate solidification ground, steel wood mixing framed bent is set up on the ground being cured, then steel rail laying is mixed in steel wood
Close on framed bent as displacement slideway；By jack jacking transformer, two displacement slideways are laid on respectively by direction of displacement
Transformer body lower end, and two pieces of slide plates are placed on each unilateral displacement slideway, transformer is dropped on slide plate, then
After the pushing tow such as locker, hydraulic push rod equipment is combined, slide plate is elapsed, slide plate is moved on displacement slideway, so that becoming
Depressor realizes displacement.
Analyzed by Force Calculation, the following transformers of voltage class 500kV are unloaded, operation in place, mainly using single steel
Rail is laid on the unilateral displacement slideway shifted as transformer on displacement framed bent；Voltage class 500kV and above transformer unload,
Operation in place, is at least laid side by side on the unilateral steel wood mixing framed bent shifted in transformer, this unilateral shifting using two one steel rails
, easily there is the problems such as rail bending, rail movement and inconvenient adjustment in position slideway.
During unilateral as the transformer displacement slideway of two one steel rails, often taking will side by side spread after the scene occasional combination of two one steel rails
It is located on steel wood mixing framed bent, the rail spacing of occasional combination is adjusted according to site environment, and the located lateral between two one steel rails is normal
Using manpower control, vertically moved between often occurring unilateral two one steel rail in shifting process, horizontal spacing change and rail folding
Curved the problems such as, very burden is brought to transformer shift operation.Such as two one steel rails are laid side by side in steel plate with certain spacing
On, directly welded so as to two one steel rails form a whole as the unilateral displacement slideway of transformer by steel plate and rail.This
Kind of mode solves displacement slideway and easily occurs rail movement, rail bending and adjustment inconvenience etc. in use really asks
Topic, but because rail has welding interior stress in welding process, easily occur rail fracture phenomenon in use, increase
The risk of transformer shift operation.
The content of the invention
The utility model purpose is to provide a kind of high-power transformer displacement combination rail slideway, shortens transformer and unloads in place
Duty cycle, operation intensity is reduced, while, it is ensured that transformer is safe and stable during shift operation, improves operating efficiency,
Save installation cost.
To achieve these goals, the utility model is adopted the following technical scheme that：
High-power transformer displacement combination rail slideway, including steel plate, rail, electro-insulating rubber pad, pressing plate, rivet and hanger,
Its feature is：Two one steel rails are parallel to each other and are laid on steel plate, and electro-insulating rubber pad is provided between rail foot surface and steel plate；Steel
Rail, electro-insulating rubber pad and steel plate three are fixed together by several pressing plates and several rivets；In two one steel rails
Two hangers are welded with the steel plate in centre position.
The characteristics of the utility model, also resides in：
Described pressing plate is an inclined-plane, the gradient that convex edge is provided with the gradient and the rail flange of rail on inclined-plane with the contact surface of rail
It is identical；Pressing plate is used to be welded and fixed and is connected with steel plate.
Described rivet is each die in every one steel rail two ends, and rail origin symmetry arrangement is prolonged in die position, itself and steel
Plate is used and is welded and fixed connection, specifically：By in the preformed hole of rivet reeve rail and electro-insulating rubber pad, incited somebody to action in steel plate reverse side
Rivet welds together with steel plate.
Compared with prior art, the utility model has the advantages that：
During the utility model substation transformer more than 500 kilovolts is unloaded in place, substantially reduce transformer and unload just
Position duty cycle, reduce operation intensity, while, it is ensured that transformer is safe and stable during shift operation.By pressing plate
With steel plate welding fixed rail indirectly, it is to avoid rail bending, fracture and dislocation movement, reduce because manpower adjusts rail spacing
And make injury to personnel probability, and Work tool cost is saved, improve operating efficiency.
