Detect a device for anchor axial force and bending moment force, this device has the anchor pole of a solid elongated cylindrical, and in one end of anchor pole, have one section of external thread, on external thread, Matching installation has fastening nut; The groove corresponding with foil gauge and wire shape is provided with at the outside surface of anchor pole, in a groove, surrounding symmetry is pasted with KFEM high rate elongation foil gage, and the groove extension that the wire of foil gauge is arranged on anchor pole is guided to outside the end of anchor pole, concentrates and gathers on line trap.This kind of device detecting anchor axial force and bending moment force can not only detect the axle power distribution of anchor pole, and can detect again the bending moment force distribution of anchor pole, and result directly shows over the display, can the distribution of direct vision power, and this apparatus structure is simple, easy to use.
Description
Technical field
the utility model relates to the device of a kind of detection axis power and bending moment force, especially a kind of device detecting anchor axial force and bending moment force.
Background technology
anchor pole or anchor cable reinforcing are the important form of rock-reinforcing, wherein anchor pole has hollow bolt and solid anchor pole, anchor pole is widely applied in the Geotechnical Engineerings such as tunnel, mine, traffic tunnel, deep basal pit reinforcing, but not yet completely clear to the action principle of anchor pole, the stressed of anchor pole and anchor pole load transfer mechanism in theory.Therefore, adopt the method for actual measurement to understand the duty of anchor pole at the stressed of country rock inside and deformation behaviour, grasp anchor pole, to improving anchorage theory, accumulation design has important meaning through, adjustment in time or Amending design and arrangement and method for construction and forecast dangerous situation.
the internal force status of current anchor pole detects the main method adopting actual measurement, adopts dynamometry anchor, comprise resistance-strain type of dynamometer anchor pole, inductance type force-measuring anchor stock, steel chord type force-measuring anchor stock during actual measurement.Above-mentioned force-measuring anchor stock only can measure axle power and the distribution of axle power of anchor pole, can not measure the moment of flexure of anchor pole.But when studying rockbolt stress and deformation behaviour, not only to knowing axle power and moment of flexure, also needing by measuring the maximum position finding out greatest axis power, moment of flexure simultaneously.So provide one to detect anchor axial force, a kind of device detecting anchor axial force and bending moment force that can detect again bending moment force is just very necessary.
Summary of the invention
only can measure axle power and the distribution of axle power to overcome existing force-measuring anchor stock and can not measure the problem of anchor axial force and bending moment force simultaneously, the utility model provides a kind of device detecting anchor axial force and bending moment force.This kind of device detecting anchor axial force and bending moment force can not only detect the axle power of anchor pole, and can detect the bending moment force of anchor pole.And structure is simple, easy to use.
the utility model solves the technical scheme that its technical matters adopts: a kind of device detecting anchor axial force and bending moment force, comprising: line trap, fastening nut, foil gauge, anchor pole; This kind of device detecting anchor axial force and bending moment force has the anchor pole of a solid elongated cylindrical, and in one end of anchor pole, have one section of external thread, on external thread, Matching installation has fastening nut; The groove corresponding with foil gauge and wire shape is provided with at the outside surface of anchor pole, in a groove, surrounding symmetry is pasted with KFEM high rate elongation foil gage, and the groove extension that the wire of foil gauge is arranged on anchor pole is guided to outside the end of anchor pole, concentrates and gathers on line trap.
during use, line trap is connected on ASM2-30/20/10 strainmeter, the axle power namely suffered by observable anchor pole and bending moment force, thus detects the change of deep ground.
the beneficial effects of the utility model are: this kind of device detecting anchor axial force and bending moment force can not only detect the axle power distribution of anchor pole, the bending moment force distribution of anchor pole can be detected again, and result directly shows over the display, can the distribution of direct vision power, and this apparatus structure is simple, easy to use.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further illustrated.
accompanying drawing 1 is structural principle schematic diagram of the present utility model.
1. line traps, 2. fastening nut, 3. foil gauge, 4. anchor pole in figure.
Embodiment
in FIG, a kind of device detecting anchor axial force and bending moment force, comprising: line trap 1, fastening nut 2, foil gauge 3, anchor pole 4; This kind of device detecting anchor axial force and bending moment force has the anchor pole 4 of a solid elongated cylindrical, and in one end of anchor pole 4, have one section of external thread, on external thread, Matching installation has fastening nut 2; The groove corresponding with foil gauge 3 and wire shape is provided with at the outside surface of anchor pole 4, in a groove, surrounding symmetry is pasted with KFEM high rate elongation foil gage 3, and the groove extension that the wire of foil gauge 3 is arranged on anchor pole 4 is guided to outside the end of anchor pole 4, concentrates and gathers on line trap 1.
during use, line trap 1 is connected on ASM2-30/20/10 strainmeter, the axle power namely suffered by observable anchor pole 4 and bending moment force, thus detects the change of deep ground.
