Abstract

The invention relates to a double-hook tightener inspection and maintenance test device and a use method. The device comprises a rack, a fixing device and a lead screw rotating device, wherein a platform is installed on the rack, the fixing device is fixedly installed on the platform, two lead screw rotating devices are symmetrically installed on the platform and located on the left side and the right side of the lead screw rotating device, a steel wire brush and an oil nozzle are sequentially installed on the left side and the right side of the fixing device, and rail grooves are formed in the platform and the left side and the right side of the fixing device in the transverse direction. The lead screw rotating device comprises a movable base and a transversely-arranged hydraulic oil cylinder which are sequentially arranged from inside to outside. An outer connecting block is mounted at the outer end of the movable base; the outer connecting block is connected with the piston rod of the hydraulic oil cylinder through a tension sensor; rolling wheels are installed at the lower end of the movable base and located in the rail grooves, the motor and the speed reducer which are sequentially connected are installed on the movable base, and an inner connecting block is installed on the output shaft of the speed reducer. Integrated operation of inspection and maintenance tests of thedouble-hook tightener is achieved, and the efficiency and the quality of the inspection and maintenance tests of the double-hook tightener are improved.

Description

technical field [0001] The invention relates to a double-hook wire tensioner inspection and maintenance test device and a use method, belonging to the technical field of power transmission and transformation construction. Background technique [0002] The double-hook wire tensioner is a tool used for tightening the stay wire, adjusting the position of equipment or equipment, and replacing insulators or other equipment during wire erection construction. It includes rod sleeves, screw rods, ratchet components and other components. During the use of the double-hook wire tensioner, impurities will be attached to the surface of the screw rod, and rust phenomenon will also occur, which affects the normal use of the double-hook wire tensioner and reduces its service life. According to the "Preventive Test Regulations for Small Construction Equipment Used in Electric Power Work", the double hook wire tensioner must undergo corresponding mechanical tests every year before it can cont...
