Description

Technical Field

[0001] The utility model relates to the technical field of anchor rod testing, in particular to an anchor rod locking force testing device. Background Art

[0002] The anchor rod is divided into a free section and an anchoring section. The free section refers to the area that transmits the tension at the anchor rod head to the anchor body. Its function is to apply prestress to the anchor rod. The anchor rod locking force is a comprehensive reflection of the anchor rod material, processing and construction and installation quality. It is a basic content of anchor rod quality inspection. The test evaluation result of the ultimate pull-out bearing capacity of the anchor rod is determined as the anchor rod locking force.

[0003] After searching (application number: 202023010554.X), it can be learned that an anchor locking force testing device includes a base, a U-shaped frame is fixedly installed on both sides of the top of the base, a first electric hydraulic cylinder is fixedly installed in the middle of the bottom end of the U-shaped frame, a cross plate is fixedly installed at the telescopic end of the first electric hydraulic cylinder, a tensile tester is fixedly installed at the bottom end of the cross plate, a fixed seat is placed in the middle of the top of the base, and the top of the fixed seat is connected to the anchor.

[0004] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: although the device has a good top fixing structure, its disassembly and assembly efficiency is not ideal, which affects the anchor test efficiency to a certain extent for batch testing. At the same time, a push rod motor and components are arranged at the bottom to limit the fixed seat, but the test is an upward pulling force test, and the transmission shaft and the locking assembly of the motor are very easy to deform. The cost of setting up this structure and the subsequent maintenance cost are relatively high, and the practicality is not ideal, which urgently needs to be improved. Therefore, we propose an anchor locking force testing device. Utility Model Content
