Description

Technical Field

[0001] The utility model belongs to the technical field of excitation transformer transportation, and relates to a transportation device suitable for transporting large-scale excitation transformers in narrow areas. Background Technique

[0002] The excitation transformer mainly provides excitation current for the generator. In large power station units, there are many excitation transformers. The excitation transformers are uniformly arranged in the corresponding areas of the unit section. When the excitation transformer needs to be replaced, the standby excitation transformer needs to be transported to the corresponding position. The excitation transformer is relatively heavy, about 9 tons, and has a large volume. Due to the limited space in the excitation transformer area, hoisting and using large mechanical equipment cannot be carried out. The traditional transportation method mainly relies on manual labor using tools for transportation. This method not only has extremely low efficiency and consumes a large amount of manpower and material resources, but also takes a long time once the transportation distance is too long, which will affect the power generation and maintenance tasks of the hydropower station unit. Moreover, there are relatively large potential safety hazards, which will cause harm to people and equipment.

[0003] At present, during the transportation of the excitation transformer, the travel route is basically determined. There are many places with relatively narrow and right-angle turns during the transportation process. The minimum width dimension is 2070mm - 2400mm. There is a fixed cable bracket on the left side of the excitation transformer shell, forming an asymmetric structure, and the distance from the passing width is only 700mm. How to ensure that the excitation transformer can pass safely in a relatively narrow position is a problem that needs to be solved at present. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a transportation device suitable for transporting large-scale excitation transformers in narrow areas, realizing the transfer of giant excitation transformers in narrow channels and ensuring the stability during the transportation process.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a transportation device suitable for transporting large-scale excitation transformers in narrow areas, which includes a transportation seat, an electric tank, and a roller seat; the front side of the transportation seat is snap-connected to an electric tank, and two roller seats are fixed to the rear side of the transportation seat; symmetric and forward and reverse electric wheels are respectively arranged on both sides of the electric tank; a plurality of load-bearing rollers are arranged at the bottom of the wheel frame of the roller seat.

[0006] The transportation seat is a hollow frame structure connected by profiles; a plug-in column is arranged on the front side of the transportation seat.

[0007] A turntable is arranged on the electric tank, and a card slot is arranged on the turntable.

[0008] The roller seat includes a wheel frame with a hollow structure. A connecting plate is arranged on the upper part of the wheel frame, and a plurality of load-bearing rollers connected to the wheel frame are arranged on the lower part of the connecting plate.

[0009] On both sides of the front of the transfer seat, stabilizing seats are respectively arranged, and the electric tank is located between the two stabilizing seats.

[0010] The stabilizing seat includes a support plate. A screw rod is connected to the support plate and passes through the stabilizing seat to be in threaded cooperation with the stabilizing seat. Two locking nuts on the screw rod clamp the stabilizing seat.

[0011] The main beneficial effects of the present utility model are as follows:

[0012] The giant excitation transformer is placed on the upper part of the transfer seat. The electric wheels of the electric tank are started, driving the excitation transformer on the transfer seat to travel along the narrow passage. The load-bearing rollers on the roller seat rollingly contact the ground, which is labor-saving, convenient for transfer, and safe and reliable.

[0013] When turning, the electric wheels on both sides of the electric tank rotate forward and backward respectively to achieve turning, which is beneficial for passing through a narrow passage with a turning angle.

[0014] By rotating the screw rod to adjust the height of the support plate from the ground, a certain gap is maintained between the support plate and the ground. If the transfer seat is about to tilt, one side of the support plate contacts the ground, preventing excessive tilting angle and overturning. Description of the Drawings
