Abstract

The invention discloses a detecting trolley of a hydraulic torque wrench. The detecting trolley comprises a tool trolley and a torque detecting mechanism disposed on the tool trolley. The torque detecting mechanism comprises a base, a static torque sensor, a fixing plate, a needle bearing and counter-acting force columns. The base is connected with the tool trolley through base fixing bolts. The static torque sensor is disposed in the mounting groove of the base. The output shaft on the lower portion of the static torque sensor is mounted into the connecting square hole in the lower portion of the base. A fixing plate is connected to the upper end of the base through positioning pins. The fixing plate is provided with a mounting through hole right above the mounting groove. The needle bearing is disposed in the mounting through hole. The input shaft on the upper portion of the static torque sensor is mounted into the needle bearing. The fixing plate is provided with counter-acting force columns mounting holes beside the mounting through hole. A lining is disposed in each counter-acting force columns mounting hole. The lower portion of each counter-acting force column is connected into the corresponding lining. By the detecting trolley, torque precision detection of the hydraulic torque wrench can be completed in a production field.

Description

technical field [0001] The invention relates to a detection trolley of a hydraulic torque wrench, which is used for testing the torque accuracy of the hydraulic torque wrench. Background technique [0002] Hydraulic torque wrench is usually used in construction, maintenance and emergency repair work in shipbuilding, petrochemical, construction, electric power, mining, metallurgy and other industries. It is an important tool for the installation and removal of large-size bolts and cannot be replaced by other tools. The hydraulic torque wrench is easy to carry and easy to use. It can provide larger and more accurate torque, and the torque repeatability can reach ±3%. [0003] According to relevant statistics, about 50% of equipment failures are caused by bolt problems, and the number of major equipment accidents caused by bolt problems is also very alarming. Therefore, in the process of equipment installation, maintenance and gun repair, the torque accuracy requirements for f...
