Abstract

The invention discloses a hydraulic coupler over-temperature protection device and a repairing method thereof. The hydraulic coupler over-temperature protection device comprises a fusible plug (2) and a proximity switch (3), wherein the proximity switch (3) is positioned on one side close to the fusible plug (2); the central axes of the proximity switch and the fusible plug (2) are coincided with each other during initial installation; the fusible plug (2) comprises a cylinder barrel, and a piston and a piston rod (5) which are positioned in the cylinder barrel; the cylinder barrel is partitioned into a rod-including cavity and a rod-free cavity by the piston; the rod-including cavity is communicated with a hydraulic oil cavity (1); the rod-including cavity is filled with fusible metal (6), and is provided with a channel through which a fused fusible metal flows out; when the fusible metal is filled into the rod-including cavity, the distance between piston rod (5) and the proximity switch (3) is larger than a detected distance; and after the fusible metal flows out by fusing, the distance between piston rod (5) and the proximity switch (3) is not greater than the detected distance. During repairing, the fused fusible plug (2) and a fusible alloy to be filled are heated, and the fusible alloy is fused into liquid and then is filled into the fusible plug (2); and after the fusible alloy is cooled and condensed, the device can be used once again.

Description

technical field [0001] The invention relates to the technical field of hydraulic couplings, in particular to an over-temperature protection device for a hydraulic coupling; the invention also relates to a repair method for an over-temperature protection device for a hydraulic coupling. Background technique [0002] The hydraulic coupling is a non-rigid coupling with liquid as the working medium, also known as the hydraulic coupling. The pump wheel and the turbine of the hydraulic coupling form a closed working chamber that can circulate the liquid. The pump wheel is installed on the input shaft, and the turbine is installed on the output shaft. When the power machine (internal combustion engine, electric motor, etc.) drives the input shaft to rotate, the liquid is thrown out by the centrifugal pump wheel. This high-speed fluid enters the turbine and drives the turbine to rotate, transferring the energy obtained from the pump wheel to the output shaft. Finally, the liquid r...
