Problems solved by technology

[0011] The most important factor restricting efficiency: applying pre-tightening force to the connection pair needs to be applied manually with a torque wrench, the work intensity is high, and people are prone to fatigue
[0012] The standard stipulates that the pretightening force of the connecting pair is 190KN, but human control is not so precise
The force applied is generally between 190KN and 210KN, which will cause certain errors in the test results

Abstract

The invention discloses an automatic detection device for an anti-slip coefficient, and relates to the technical field of anti-slip coefficient detection devices. The device comprises a work control table top; a hardware assembly is fixed to the upper surface of the work control table top, the output end of the work control table top is in signal connection with a pressure sensor, and a connecting pair is in sliding fit with the work control table top. The pressure sensor is in threaded running fit with the connecting pair, and the connecting pair comprises a connecting pair sliding table and a sliding coefficient plate; and the sliding coefficient plate is in sliding fit with the connecting pair sliding table. After the anti-slip coefficient connecting pair is installed on the device, software controls the motor to operate, the output torque is increased through the RV speed reducer, and the torque output requirement is met. And when the pressure sensor on the high-strength bolt reaches a preset value, the motor is controlled to stop, and the high-strength bolts of different specifications provide different output torques.

Description

technical field [0001] The invention belongs to the technical field of anti-slip coefficient detection devices, in particular to an anti-slip coefficient automatic detection device. Background technique [0002] The anti-slip coefficient is mainly used in the detection test of high-strength bolts of steel bridges. The JTG / TF50-2011 standard requires that the plate surface (friction surface) of the component bolted with high-strength bolts on the construction site must be treated, and the value of the anti-slip coefficient after treatment should meet the design requirements. With the rapid development of China's economy and the country's domestic demand, infrastructure investment has increased significantly. Especially with the implementation of the high-speed rail strategy, the mileage of railway and highway construction has increased year by year, and the number of large-span, multi-lane, and heavy-duty bridge projects has also increased significantly, and more and more st...
