Description

Technical Field

[0001] The invention relates to the technical field of engineering anchoring detection, and in particular to an anchor rod anchoring strength detection device. Background Art

[0002] Anchor support technology has the advantages of strengthening rock mass, reducing the deadweight of structures and saving engineering materials. In recent years, it has gradually developed into the main technical means for preventing and controlling geological disasters, and has been widely used in geotechnical engineering fields such as slopes, foundation pits and tunnels.

[0003] Generally, anchor rods are installed perpendicular to the surface of the supporting part (e.g., the surface of the tunnel), but the surface of the tunnel is mostly uneven. Therefore, when the anchor rod is anchored, it is impossible to ensure that the anchor rod is perpendicular to the tunnel surface, and there will be a certain angle. When the axis of the anchor rod is not perpendicular to the tunnel surface and is at a certain angle, the tension originally perpendicular to the supporting part (e.g., the tunnel) will be decomposed into two components, one along the axis of the anchor rod, and the other perpendicular to the supporting part (e.g., the tunnel). When the anchoring effect of the anchor rod is tested in the relevant technology, only the pull-out test in the direction of the axis of the anchor rod is performed. The obtained anchor rod anchoring strength data is single, which cannot reflect the comprehensive anchoring strength of the anchor rod under actual working conditions, and cannot ensure its safety and reliability in actual applications.

[0041] In order to clearly explain the above embodiment, in one embodiment of the present invention, as Figure 3 As shown, the limiting through groove 8 may include: a groove 11 and a clamping groove 12.

[0045] The axis of the driving shaft of the first motor 14 is coaxially arranged with the center of the slot 12 when it is completed into a complete sphere. It should be noted that the slot 12 is a spherical crown with a flat top, so the center of the slot 12 is the center of the sphere.

[0046] In one embodiment of the present invention, Figure 2 As shown, the horizontal driving device 3 may include: a workbench 17 , a second motor 18 , a first ball screw 19 , a first ball slider 20 and a connecting plate 21 .

[0050] It can be understood that the first hydraulic telescopic device 39 described in this embodiment can be set on the workbench 17, and the first hydraulic telescopic device 39, the hydraulic lifting device 40, and the second hydraulic telescopic device 41 can adjust the working position of the second clamping member 42 to facilitate the axial pulling detection device 38 to perform pulling detection on the anchor rod 101 to be tested in its axial direction.

[0051] Specifically, relevant personnel take the anchor rod 101 to be tested and install it on the anchor rod fixing assembly 1. At this time, the anchor rod is set horizontally (parallel to the upper surface of the workbench 17), and the horizontal driving device 3 can move the push plate 6 to a suitable working position through the rotating device 4 (the working position varies according to the length of the anchor rod 101 to be tested).

[0054] When it is necessary to test the pull-out force of the anchor rod 101 in two directions, Fig.10As shown, after adjusting the inclination angle of the push plate 6, the hydraulic lifting device 40 can be controlled to move horizontally through the first hydraulic telescopic device 39, and the hydraulic lifting device 40 can control the second hydraulic telescopic device 41 to move vertically to a suitable height. The telescopic end of the first hydraulic telescopic device 39 retracts, and the anchor rod 101 to be tested is clamped by the second clamping member 42. The second hydraulic telescopic device 41 can pull the anchor rod 101 to be tested along the axial direction of the anchor rod 101 to be tested, and together with the inclined push plate 6, apply a pulling force to the anchor rod to obtain the anchoring strength data of the anchor rod 101 to be tested in actual use (the performance of the anchor rod 101 to be tested when it is subjected to a force perpendicular to the support portion and an axial force).
