Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Example is not intended to limit the scope of the present invention for illustrating the utility model.
In the description of the present invention, it should also be noted that, unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, can also be electrical connection；It can be directly connected, it can also be indirectly connected through an intermediary.
For the ordinary skill in the art, visual concrete condition understands that above-mentioned term in the present invention specific contains
Justice.
Fig. 1 is that the protective device that the utility model embodiment provides applies vertical view at tunnel；Fig. 2 be Fig. 1 just
View；Fig. 3 is the side view of Fig. 1.
As shown in figs. 1-3, the utility model provides a kind of protective device of big gun pick strata behavior analysis of roadway monitoring instrument, including
Top protection and side shield.Monitoring instrument of the top protection for protection setting in tunnel top surface is destroyed from collapsing stone, side
Monitoring instrument of the protection for protection setting in tunnel side is destroyed from collapsing stone.Top protection and side shield include rectangular
The flexible protective main body of laminated structure.Flexible protective main body after mounting, can slow down or eliminate using the plastic deformation of its own
The impulsive contact force of stone is collapsed, and then plays the role of monitoring for protection instrument.Preferably, the material of flexible protective main body uses mining skin
Band, such as made by cutting waste and old mining belt conveyor, the recycling of junk can be realized in this way, while can also be played
The effect of instrument is protected, and then reduces production cost.
As shown in Figures 1 and 2, a line of the flexible protective main body of top protection is along connector is equipped with, so that soft
