Embodiment 1
[0047] The structure of the anchor (cable) support structure test and the comprehensive test device for anchorage system performance includes a frame 1, a loading mechanism 2, a testing mechanism 3 and a test piece 4, such as Figure 1 to Figure 5 As shown, its frame 1 includes a base 11 and an operating table 12, the loading mechanism 2 includes a loading frame 21, an anchor rod chuck 22, a pressure plate, a drawing hollow cylinder 31 and a plurality of loading cylinders 24, and the testing mechanism 3 includes Torsion motor 32 bolter rig 33, and monitoring devices such as acoustic emission probes, stress and displacement sensors, and test piece 4 includes anchoring components such as test bolt 41, rock test piece 42, steel belt 43, anchor net 44, and tray 45. The device can simulate the actual ground stress conditions through the loading mechanism 2, use the pulling hollow cylinder 31 of the testing mechanism 3 to apply tension to the test anchor 41, the torsion motor 32 prov...
Embodiment 2
[0057]The structure of a bolt support structure test and anchoring system performance comprehensive test device includes a frame 1, a loading mechanism 2, a testing mechanism 3 and a test piece 4, and the frame 1 includes a base 11 and an operating table 12, and the loading mechanism 2 Including loading frame 21, anchor chuck 22, pressure bearing plate, drawing hollow cylinder 31 and 12 loading cylinders 24, testing mechanism 3 includes torsion motor 32 and anchor drilling machine 33, as well as stress and displacement sensors, acoustic emission probes, etc. The monitoring device, the test piece 4 includes a test bolt 41 , a rock test piece 42 , a steel belt 43 , an anchor net 44 and a pallet 45 .
[0058] The frame includes a base 11 and an operating table 12, the base 11 is used to fix various components of the loading mechanism 2, and the operating table 12 mainly assists the torsion motor 32 and the rock bolter 33 to work. The upper surface of the base 11 is provided with ...
Embodiment 3
[0074] In this embodiment, a layer-separated loading oil cylinder is set between the two-axis frames, such as Figure 15 As shown in Fig. 1, the layer-separated anchoring control of rock mass is simulated by the layer-separated loading cylinder, and the mechanism and characteristics of the layer-separated layer, as well as the supporting mechanism and supporting capacity method of the bolt are studied.
[0075] The improvement of the structure of the testing machine includes that a separation jack 5 is arranged between the biaxial frames 211, the upper part of the biaxial frames 211 slides along the pillars, and the biaxial frames 211 can slide along the through groove 111 on the base. The test steps include: First, make a simulated test piece of similar material, or take the rock on site to make a simulated test piece, polish the surface of the simulated test piece to make it smooth, match the size of the simulated test piece with the size of the space surrounded by the pressu...
