Description

Technical Field

[0001] The utility model belongs to the technical field of anchor rod detection, in particular to a nut clamp of an anchor rod puller. Background Art

[0002] An anchor rod is a component used to reinforce and support structures. It is usually made of materials such as steel bars, steel pipes, prestressed steel bars or fiberglass. The function of the anchor rod is to transfer the load of the structure to the foundation or other bearing layers through its tensile strength, thereby enhancing the stability and seismic resistance of the structure.

[0003] To ensure the reliability and safety of anchor bolts under tension, their tensile properties need to be tested and evaluated, which is why an anchor puller is used. An anchor puller is a specialized instrument used to test the tensile properties of anchor bolts. It applies a pulling force and monitors the anchor bolt's response during the pulling process, including the magnitude of the pulling force and the deformation of the anchor bolt. This test can provide performance parameters of the anchor bolt under tension, such as tensile strength and deformation characteristics. To ensure that the anchor bolt does not move or detach from the instrument during the pulling test and to maintain a stable testing environment, a nut clamp is used on the top of the anchor bolt to protect it from damage or deformation, ensuring the accuracy and durability of the test and avoiding inaccurate test results due to uneven pulling force. However, the nut clamp that secures the anchor bolt often lacks a support structure, resulting in insufficient stability and reliability. The aforementioned technology suffers from the lack of a support structure for the nut clamp, which affects its stability and reliability, thereby compromising the testing effectiveness of the puller.

[0026] The working principle of this utility model:

[0027] When the height of the nut clamp 2 needs to be adjusted, first separate the two mounting blocks 203 from the screw and nut fixed by the limit block 204. At this time, the connecting rod 202 can be pulled to drive the clamping block 201 to move to the left, so that the clamping block 201 is out of contact with the anchor rod 103. Then, the U-shaped block 703 is pulled to the left and the adjusting block 701 is moved to the left, so that the adjusting block 701 is moved out from the inside of the adjusting plate 5. At this time, the moving block 4 can drive the limit block 204, the connecting rod 202, the two mounting blocks 203 and the clamping block 201 to move upward or downward. The movement of the adjusting block 701 will cause the two extrusion springs 702 to deform. After the clamping block 201 moves to the required position, the U-shaped block 703 is released. Under the elastic action of the two extrusion springs 702, the adjusting block 701 rebounds to the inside of the adjusting plate 5, so that the moving block 4 and the adjusting plate 5 are fixed, and the limit block 204 is fixed after adjusting the height.
