Problems solved by technology
[0002] The transformer is cooled by the submersible pump. When the submersible pump fails, it needs to be maintained and replaced. The maintenance and conversion process requires disassembly and assembly of the submersible pump, but the current maintenance and replacement methods are relatively inefficient
Because the submersible pump and the transformer are generally connected by a flange, and the submersible pump is relatively heavy. After removing one or two fixing screws, the balance will be lost under the action of gravity of the submersible pump, and the other fixing screws will get stuck on the flange, resulting in The submersible pump cannot be disassembled. Secondly, the installation position of the submersible pump is relatively low, which makes it difficult to disassemble.

The invention discloses an oil-submerged pump replacing, maintaining and operating device of a transformer. When in use, an adjusting rod is rotated forward firstly, the threaded section with oppositedirection of turning on the adjusting rod drives pivots of two scissor units to be close to each other, supporting arms on the two sides of each scissor unit are lowered, a first lifting platform islowered to a lower position, and then the whole device is sent to the lower part of an oil-submerged pump installed at the lower position, and then the adjusting rod is reversely rotated to drive thepivots of the two scissor units to be far away from each other, so that the supporting arms on the two sides of each scissor unit rise, the first lifting platform is lifted to make contact with the oil-submerged pump, and support is formed for the heavy oil-submerged pump, so that the disassembly and assembly are simple; and in the process, the two pivots and the adjusting rod also rise and fall,a telescopic rod rotationally connected to the smooth section of the adjusting rod is elongated or shortened, the support is always formed in the middle of the adjusting rod, and the stability of thewhole device is guaranteed.
Description
technical field [0001] The present invention generally relates to the technical field of electric power auxiliary equipment, in particular to a transformer submersible pump replacement and maintenance operating device. Background technique [0002] The transformer is cooled by the submersible pump. When the submersible pump fails, it needs to be maintained and replaced. The maintenance and conversion process requires disassembly and assembly of the submersible pump. However, the current maintenance and replacement methods are relatively inefficient. Because the submersible pump and the transformer are generally connected by a flange, and the submersible pump is relatively heavy. After removing one or two fixing screws, the balance will be lost under the action of gravity of the submersible pump, and the other fixing screws will get stuck on the flange, resulting in The submersible pump cannot be removed. Secondly, the installation position of the submersible pump is relative...
