Description

Technical Field

[0001] The utility model relates to bolt detection, in particular to a device for bolt detection. Background Art

[0002] When a through-hole jack is used to pull a diagonal bolt for tensile test, in order to ensure that the force application direction of the through-hole jack is consistent with that of the diagonal bolt, a test stand is required to change the force application direction of the through-hole jack. The traditional test stand is disclosed in CN201922120710.9, a bolt uplift test device, which can even adjust the inclination angle. However, it ignores a problem. It should be noted that at the construction site, the diagonal bolts to be detected are already fixed, and only the test stand can be moved to cooperate with the diagonal bolts. Such a structure is not convenient to cooperate with the diagonal bolts. Content of the Utility Model

[0003] The utility model provides a device for bolt detection, aiming to solve the problem of inconvenient use of the traditional test stand.

[0004] The technical solution of the utility model is as follows:

[0005] A device for bolt detection is used for the tensile test of diagonal bolts. The device includes a test stand and a through-hole jack. The test stand includes a left support, a right support, and a support plate. The support plate is mounted on the left support and the right support, with its bottom suspended. The support plate is inclined, and its inclination angle is the same as that of the diagonal bolt. The support plate is provided with a hole.

[0006] During the test, the diagonal bolt is placed between the left support and the right support, and its upper section passes through the hole on the support plate. The through-hole jack is installed on the support plate and connected to the upper section of the diagonal bolt to pull the diagonal bolt.

[0007] A notch for the diagonal bolt to enter and exit is provided at the upper end of the hole on the support plate.

[0008] Further refining the above technical solution, the test stand is symmetric left and right, and the hole on the support plate is located on the central axis of the test stand; with balanced force, the test stand can bear greater force.

[0009] Further refining the above technical solution, both the left support and the right support are triangular structures welded by I-beams, and their upper ends are inclined planes. The support plate is fixedly connected to the upper ends of the left support and the right support, and contacts the upper end surfaces of the left support and the right support; the structure is more firm and can bear greater force.

[0010] Further refining the above technical solution, the left support and the right support have front and rear support cross frames, and they share the front support cross frame. The front end surfaces of the left support and the right support are connected by a connecting plate; the whole test stand is more stable.

[0011] The advantages of the present utility model are as follows: reasonable design, simple structure, convenient on-site use. Place the test stand in front of the inclined anchor rod and move it backward, then the inclined anchor rod can be easily moved between the left support and the right support, enter through the notch at the upper end of the hole on the support plate, and then install the through-hole hydraulic jack to achieve the tensile test of the inclined anchor rod.
