Device for removing cap from oil sample joint in substation oil sampling operation

Abstract

The invention discloses a device for removing a cap from an oil sample joint in substation oil sampling operation. The device comprises a positioning bracket, an oil sample joint head cap rotating mechanism and an electric torque handle with a power source, wherein the positioning bracket comprises a bottom hexagonal socket sleeve and a top plate connected with the bottom hexagonal socket sleeve,the bottom hexagonal socket sleeve is matched with the hexagonal bottom of the oil sample joint to achieve tool positioning, and the middle position of the top plate is provided with a bearing installation hole in which a sunken bearing is installed; the oil sample joint head cap rotating mechanism comprises a structure frame, a sunken intermediate plug-in transmission gear connected to the structure frame and three geared pawl fingers arranged around the sunken intermediate plug-in transmission gear, the sunken intermediate plug-in transmission gear is in meshing transmission with the gearedpawl fingers, and the center of the sunken intermediate plug-in transmission gear is provided with a transmission hole; and the electric torque handle with the power source comprises a transmission rod, and the transmission rod penetrates through the sunken bearing on the top plate and is inserted in the transmission hole of the sunken intermediate plug-in transmission gear. The device can improvethe sampling working efficiency, reduce the sampling uncapping difficulty and improve the safety and reliability of one-site sampling uncapping work.

Description

technical field [0001] The invention belongs to the technical field of electric power safety production, and in particular relates to a special tool developed to solve the difficulty in opening the oil sample joint when the oil sample is taken from equipment in a substation. Background technique [0002] 1. Current status of oil sampling [0003] Sampling is an important part of oil work, and opening the oil sample connector cap is an essential part of sampling work. With the gradual expansion of the substation scale and the gradual increase in the number of substation equipment, the corresponding equipment that needs to take oil samples has also increased. At present, the oil sample joints are mainly Hangzhou Kelin and similar structures. The cap and the oil sample joint are screwed together by threads and finally compressed and sealed by a rubber ring. The commonly used tools for opening the oil sample joint cap are pipe wrench, water pump pliers and adjustable wrench. ...
