Abstract

The invention discloses a tool special for replacement of an extra-high-voltage alternate-current transformer oil-submerged pump. The tool comprises a trolley, two manual hydraulic pumps are mounted on the two sides of the upper part of the trolley correspondingly, the fixed ends of the manual hydraulic pumps are connected with the trolley, the lifting ends of the manual hydraulic pumps are connected with a lifting platform, and the lifting platform comprises a second platform plate. According to the tool, a plurality of auxiliary stabilization devices are additionally arranged on the two sides of the trolley, when the trolley reaches a replacement position of the target oil-submerged pump for replacement, first lead screws of the auxiliary stabilization devices can be moved downwards by operators in a mode of rotating a handle, thus a cushion block is driven to abut against the bottom face at a certain pressure, wheels of the trolley are separated from the ground, thus sliding of the trolley in the process of replacing the oil-submerged pump is avoided, and the stability of the tool special for replacement of the extra-high-voltage alternate-current transformer oil-submerged pump during replacement of the oil-submerged pump is improved.

Description

technical field [0001] The invention relates to a special tool, more precisely a special tool for replacing a submersible oil pump of an ultra-high voltage AC transformer. Background technique [0002] Authorized announcement number CN205973620U discloses a new transformer submersible pump replacement device. We found that this oil pump replacement device is easy to slide on the ground during the actual replacement due to the universal wheel structure in the lower part, which affects the replacement of the oil pump. operate. Contents of the invention [0003] The purpose of the present invention is to provide a special tool for replacing submersible pumps of UHV AC transformers, which can add several auxiliary stabilizing devices on both sides of the cart. The first screw rod can be moved downward by the operator by turning the handle, so as to drive the cushion block against the bottom surface with a certain pressure, so that the wheels of the cart are separated from the...
