Calibrated waterproof bolt tensile force real-time monitoring device

Abstract

The invention discloses a calibrated waterproof bolt tensile force real-time monitoring device which comprises a bolt, a blind hole, a foil strain gauge, a wire, a circuit board, a display screen, a control chip, a base, a threading hole, an external thread, a groove, a mounting base, a glue guide groove, an O-shaped ring, a top cover, a transparent window and an internal thread. The display screen is fixedly connected onto the outer wall of the top end of the circuit board; the control chip is fixedly connected onto the outer wall of the top end of the circuit board; the external thread is arranged on the outer wall of one side of the base; and the internal thread is arranged on the inner wall of one side of the top cover. According to the calibrated waterproof bolt tensile force real-time monitoring device provided by the invention, a tension real-time monitoring device and the bolt are integrated into a whole, so that the sealing performance is good, the waterproof function is achieved, and the assembling and disassembling operation of the bolt is not affected; and the device can operate independently in a power supply environment, can monitor and display the tensile force of the bolt in real time, and can transmit real-time monitoring data to the outside in a wired or wireless mode.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a calibrated real-time monitoring device for waterproof bolt tensile force. Background technique [0002] Bolts are called the rice of industry. Important large-scale bolts are mainly used in the connection parts of structural parts. During the use of bolts, the tensile force of the bolts is constantly changing due to alternating loads and external influences. When the bolts exceed their Under the conditions of use, failures such as loosening and breaking occur. When the existing bolts are installed and tightened, the theoretical tensile force is only calculated through a torque wrench or a tightening force monitoring device, and the actual tensile force of the bolt cannot be directly measured. There is no way to calibrate the tensile force of the bolt. Contents of the invention [0003] The purpose of the present invention is to provide a calibrated real-time monitoring device ...
