Machine Part of Automatic Anchor Bolt Drawing Instrument

Abstract：To solve the problems in the measurement of anchor bolt drawing force testing, the paper supplies a new intelligent measuring instruments and methods which is of great significance for the development of the anchor bolt inspection. 

The main contents in this paper include the following four parts.

1. Give an overview of the technology of the anchor bolt testing measurement at home and abroad. Point out the disadvantages of the hydraulic loading measurement which was current used. And propose a new automatic anchor bolt drawing testing measuring. Identified design idea and operating steps of the automatic anchor bolt drawing instrument by comparison.

2. Study and design the overall program. Describe the measurement principle and the solutions of the key technology of the system.

3. Design the mechanical system, including the loading part, the connection frame part and the lifting part, and control system. Give the design methods of the key mechanisms. 

4. Integrate the mechanical system and control system, construct an experimental platform. Numerous of tests were conducted on the system to verify the functionality of the system is feasible.

Finally, give a summary of the work and some ideas and methods about the further work.

Keywords: Anchor bolt detection; Drawing testing; Automatic control.
