Drilling tool on flow guide plate

Abstract

The invention discloses a drilling tool on a drain plate, which is used for live work, and comprises a fixing device, a bracket, a rotating device and a drill bit for fixing on the drain plate, wherein the bracket is fixed on the fixing device, The rotating device is rotatably arranged on the bracket, the drill bit is fixed at one end of the rotating device, and a through hole for the drill bit to pass is left on the fixing device. During use, the rotating device is fixed on the drainage plate by the fixing device, and then the rotating device rotates to drive the drill bit to drill the drainage plate to avoid hair suction.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a drilling tool on a drainage plate. Background technique [0002] The diversion plate is often used when the tension tower jumps and when the busbar in the substation is introduced into lightning arresters, voltage transformers and other equipment. For the latter, because the pressure interface of the diversion plate is upward, it is easy to cause rainwater to seep in during rainy and snowy weather. Not only that, the long-term operation of the drainage plate will inevitably generate heat, and when the heat reaches a certain level, the rainwater in the crimping tube will vaporize. Once the crimping interface is corroded and blocked, the drainage plate will expand due to thermal expansion and contraction, or even rupture, which will cause hidden dangers to the safe operation of the power grid, and the crimping interface will also appear hair suction. [0003] Therefore, how to ...
