Description

Easy mobile multifunctional is crept into automatically and emulates anchor rod anchored testing stand for a kind of laboratory
Technical field
The present invention is specially related to a kind of testing stand, and in particular to a kind of laboratory creeps into easy mobile multifunctional emulation anchor pole automatically Anchorage experiment platform.
Background technique
Anchor rod anchored supporting is at home and abroad widely used at present as a kind of economical and effective support pattern It is one of the key technology that coal mine realizes that high-yield and high-efficiency must be many, China's coal-mine roadway bolt dosage in mine and Tunnel Engineering At least at ten thousand or more.But since the complexity of object is reinforced in suspension roof support, for the principle of suspension roof support, there are no one so far A unification comprehensively recognizes.Be not achieved when static pressure of the anchor pole in supporting by country rock roadway maintenance requirement initiation is caving, The accidents such as roof fall, thus for the anchor mechanism of complex conditions lower bolt, with country rock interaction relationship, stress distribution law and It is necessary that the problems such as anchorage body bearer properties, makees in-depth study.But field measurement is often subject to environmental condition Limitation and the influence of a variety of uncertain factors, it is difficult to carry out.In comparison, test indoor analog material anchor characteristics simulation Experimental study is easier to obtain internal system rule, to provide technical support for engineering.Similar material simulation experiment method one It is directly the main experimental methods of mining engineering experimental study, its essence is on experimental bench with similar with model mechanics property Material is according to the certain proportion contraction of geometric similarity at experimental model.All kinds of engineerings can be excavated on model, such as coal mine lane Road and chamber, Structures of Longwall come deformation, the movement of research engineering country rock body by simulation to engineering process and Germicidal efficacy With Mechanics Phenomenons and the dissection such as destroy in the power in supporting construction.The phase of traditional roadway bolt (rope) supporting effect Like material simulation experimental method generally be the plane simulation experimental provision for not applying confining pressure, make experimental condition seriously inclined in this way From real mine pressure condition, and can only learning prototype a section, and for research that true three-dimension stress changes Object, there are more irrationalities for no confining pressure plane simulation experimental bench.Secondly, carrying out anchor rod anchored test and anchor in laboratory Gu when agent optimization and its performance detection campaign, clamping equipment to anchor rod anchored rigid sleeve without suitable simple operations, because This, using subject knowledges such as the theory of similarity, structural mechanics, the mechanics of materials, develop a kind of three-dimensional static load, structure it is simple Rationally, it realizes to bore and beats anchor pole technique, Anchor Agent optimization can be carried out and its experimental bench of performance detection campaign is imperative.Mesh Before, still more without a kind of function, comprehensive strong achievable static loading, anchor rod anchored test and Anchor Agent optimization and its performance inspection The experiment porch for surveying campaign carries out anchor characteristics test mostly on common universal testing machine.
