Security detection structure for hydraulic wrench

Abstract

The invention provides a security detection structure for a hydraulic wrench, which includes a hydraulic wrench main body, a second nylon ring block and a second nylon hexagonal block; the left end surface of the hydraulic wrench main body is opposite to the hexagonal wrench A piece of said first nylon disc is arranged at the central position. When the staff needs to use a hydraulic wrench, they can check whether the reinforcement screws are loose by twisting the security detection device, and there is no need to look for other tools, and other inspection operations do not require the cooperation of tools. Through the setting of the security detection device, the work is reduced The steps of personnel inspection, and the inspection steps are more convenient, so that the staff will not omit the inspection steps when using the hydraulic wrench, and reduce the probability of changes that will seriously affect the work during subsequent use.

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
