Problems solved by technology

[0003] When the existing device resets the hydraulic stretcher, due to the large force generated by the reset, and because the fixing effect of the hydraulic stretcher is poor, it may be due to the force when the hydraulic stretcher is reset. The large size causes the hydraulic tensioner to fall, which affects the return of the hydraulic tensioner

Abstract

The invention discloses a hydraulic tensioner reset device for preventing jamming and deformation and an implementation method thereof. A threaded rod is connected between the inner walls of the opposite sides through bearing rotation, and the outer wall of the threaded rod is threaded with a threaded block, and a sliding connection is formed between the threaded block and the rectangular groove, and a reset plate is fixed on one side of the threaded block. A support seat is fixed on one side of the top outer wall, and a support groove is opened on the top outer wall of the support seat, and a clamping mechanism is arranged inside the support groove. The invention prevents the hydraulic tensioner from falling down due to the large force of pressurization when the hydraulic tensioner returns, thereby affecting the return of the hydraulic tensioner, and prevents the hydraulic tensioner from being pressurized due to jamming. When the hydraulic tensioner is damaged due to the large force, it is convenient to improve the return speed of the hydraulic tensioner.

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...
