Security detecting structure for hydraulic spanner

Abstract

The invention provides a security detecting structure for a hydraulic spanner. The structure comprises a hydraulic spanner body, a second nylon ring stopper and a second nylon hexagonal block; and a first nylon disc is arranged on the end surface of the left side of the hydraulic spanner body corresponding to the center position of a hexagonal spanner port. When workers need to use the hydraulic spanner, a security detecting device can be twisted to check if a fastening screw is loosened; other tools are not needed to search; other inspection operations are not needed to cooperate with the tools; through arrangement of the security detecting device, the inspection steps of the workers are reduced; and the inspection steps are more convenient, so that the workers cannot omit the inspectionsteps when using the hydraulic spanner, and the probability of bad influence on the work change in subsequent use is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical tools, and more specifically relates to a security detection structure for a hydraulic wrench. Background technique [0002] Hydraulic wrenches are used in a wide range of applications; hydraulic torque wrenches are suitable for large-sized bolts in construction, maintenance, and emergency repairs in shipbuilding, petrochemical, wind power, hydropower, thermoelectric, mining, machinery, steel mills, rubber, pipeline and other industries. It is an important tool for installation and disassembly; it is irreplaceable by other tools. It is not only easy to use, but also provides very accurate torque, and the torque repeatability is about ±3%. [0003] Matters needing attention before using the hydraulic wrench. The first and most important thing for the staff who use the hydraulic wrench to do work before each operation is to check the hydraulic wrench itself to see if its parts are complete. Whet...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a security detection structure for hydraulic wrench, to solve the problem that some skilled workers use hydraulic wrench because their own vigilance is too lax and because other tools are needed. The operation of checking the hydraulic wrench itself causes some skilled workers to omit this inspection step when using the hydraulic wrench, which leads to easy changes that seriously affect the work during use
