Abstract

The invention discloses a hydraulic tensioner resetting device capable of preventing jamming deformation and an implementation method thereof. The hydraulic tensioner resetting device comprises a fixing seat, a connecting seat is fixed to one side of the outer wall of the top of the fixing seat, a rectangular groove is formed in the outer wall of one side of the connecting seat, and a threaded rod is rotationally connected between the inner walls of the two opposite sides of the rectangular groove through a bearing; and the outer wall of the threaded rod is in threaded connection with a threaded block, the threaded block is in sliding connection with the rectangular groove, a reset plate is fixed to the outer wall of one side of the threaded block, a supporting seat is fixed to one side of the outer wall of the top of the fixing seat, a supporting groove is formed in the outer wall of the top of the supporting seat, and a clamping mechanism is arranged in the supporting groove. According to the hydraulic tensioner resetting device, the situation that a hydraulic tensioner falls down due to the fact that the pressurizing force is large when the hydraulic tensioner is reset, and accordingly resetting of the hydraulic tensioner is affected is prevented, the situation that due to jamming, the hydraulic tensioner is damaged due to the fact that the pressurizing force is large when the hydraulic tensioner is pressurized is prevented, and the resetting speed of the hydraulic tensioner is increased conveniently.

Description

technical field [0001] The invention relates to the technical field of hydraulic tensioners, in particular to a hydraulic tensioner reset device for preventing jamming and deformation and an implementation method thereof. Background technique [0002] The hydraulic tensioner is the world's advanced bolt pretensioning and removal tool. The hydraulic bolt tensioner is widely used in the pretensioning of large diameter bolts due to its simple operation, convenient use and high safety. Practice has proved that the hydraulic tensioner has little damage to the equipment, the coupling components are evenly stressed, and the reliability of the bolt connection is high. During the installation and maintenance of large-scale hydropower plant equipment, many equipment require hydraulic tensioners to install or remove bolts. When the hydraulic tensioner is used too many times, the piston will jam. If the piston does not return to its proper position, it will affect the next active strok...
