Description
Technical Field

[0002] Anchor rods are the most basic component of tunnel support in contemporary coal mines. They reinforce the surrounding rock of the tunnel so that the surrounding rock can support itself. Anchor rods are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels, dam bodies, and foundation pits. As a tensile member that penetrates deep into the stratum, one end of the anchor rod is connected to the engineering structure, and the other end penetrates deep into the stratum. The entire anchor rod is divided into a free section and an anchoring section. The free section refers to the area where the tension at the anchor rod head is transmitted to the anchor body. Its function is to apply prestress to the anchor rod. The locking force of the anchor rod is a comprehensive reflection of the quality of the anchor rod material, processing, construction and installation, and is a basic content of anchor rod quality inspection.
[0003] At present, the detection of anchor locking force uses the traditional manual reading, manual load comparison, and manual load maintenance method. This method requires testers to frequently enter the test site, read the sensor values and record them in paper documents. This method not only causes low detection efficiency and cumbersome detection process, but also poses a threat to the personal safety of testers because the test site is full of various unexpected factors.
[0004] Based on this, an anchor locking force tester is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
