A tool for disassembly and maintenance of a pressure storage cylinder of a hydraulic mechanism and a method for using the same

Abstract

The invention discloses a disassembling maintenance tool for a hydraulic mechanism pressure storage cylinder and a use method of the disassembling maintenance tool. The disassembling maintenance tool is suitable for the disassembling maintenance of a CY3 hydraulic mechanism pressure storage cylinder configured by a SW6-110kV circuit breaker. The tool includes a clamp used for clamping the pressure storage cylinder, a support, a screw rod, a screw rod sleeve fixed on the right side of the support, a front bearing and a rear bearing, wherein the front bearing and the rear bearing are arranged on the left side of the support; the clamp includes a front clamping block and a rear clamping block which are connected through a bolt and used for clamping the outer wall of the pressure storage cylinder, and the outer end of the front clamping block and the outer end of the rear clamping block are fixed with a front shaft and a rear shaft respectively; the front shaft and the rear shaft are located on the front bearing and the rear bearing respectively, the screw rod is screwed in the screw rod sleeve, and the head portion of the screw rod is provided with a thread head used for being connected with a pressure storage cylinder piston screw thread. The damage of high pressure release to the human body is prevented, the use method of the maintenance tool standardizes the operation behavior of maintenance personnel, and the safety of the maintenance personnel is ensured.

Description

【Technical field】 [0001] The invention relates to a special tool for maintenance of electric equipment, in particular to a disassembly and maintenance tool for a pressure storage cylinder of a hydraulic mechanism and a method of use thereof, which is suitable for disassembly and maintenance of a pressure storage cylinder of a CY3 hydraulic mechanism equipped with a SW6-110kV circuit breaker. 【Background technique】 [0002] The SW6-110kV circuit breaker commonly used in the 110kV power system is equipped with a CY3 hydraulic mechanism. The main energy storage component of the hydraulic mechanism is the pressure storage cylinder, which is the power source for the hydraulic mechanism. The stability and reliability of the performance of the pressure storage cylinder directly affect the normal operation of the mechanism. At the same time, due to the frequent movement of parts, serious wear, processing, assembly and other factors, the pressure storage cylinder is still a weak point...

AI Technical Summary

Problems solved by technology

However, due to the residual pressure in the pressure storage cylinder, when the piston is decomposed, high pressure release is likely to injure maintenance personnel and cause safety accidents

At the same time, the irregular operation of personnel will also cause personal injury to the maintenance personnel. For this reason, a disassembly and maintenance tool for the pressure storage cylinder of the hydraulic mechanism has been developed, and the use of the maintenance tool has been standardized.
