Specific embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only preferred embodiment of the present utility model, rather than whole embodiments.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of the utility model protection.
With reference to Fig. 1-Fig. 3, the utility model provides a kind of flexible roof bolt pull-out test device, and it includes bearing 10, inside
In the hydraulic jack 20 of middle control, pull bar 30 and drawing instrument 40.
Bearing 10 is acted against in ramped surfaces 20, and the bearing 10 includes top surface 11 and is arranged on the height of the lower section of top surface 11
Adjustable supporting leg 12, the center of top surface 11 offers perforation 13.With reference to shown in Fig. 1 and Fig. 2, the supporting leg 12 is relative
It reach out to setting in top surface 11.Hydraulic jack 20 is withstood on the top surface 11 of bearing 10, and pull bar 30 passes through bearing top surface 11
On perforation 13 and hydraulic jack 20 and extend to outside, pull bar 30 is provided with drag hook 31, drag hook adjacent to the end of bearing 10
31 are combined with the end of flexible roof bolt 50, and being provided with anchor on the end extended outside hydraulic jack 20 of pull bar 30 grabs intermediate plate
