Description
Technical field
The present invention relates to mine laneway technical field of construction, specially a kind of mining tunnel deformation monitoring equipment.
Background technology
Lane surface displacement monitoring is the substance of strata behavior analysis of roadway monitoring, and lane surface displacement mainly includes roof and floor and moved
Input, the amount of crushing, pucking amount and two help shift-in amount, wherein the amount of crushing is the monitoring that mining management personnel pay close attention to the most
Project.
Mainly it is monitored, in top board construction 5-10m drilling, is arranged in drilling using all kinds of roof separation indicators at present
Two depths, shallow foundation points, cylinder chi mark variable quantity is surveyed by observing, and records the amount of crushing.Install and use at the scene roof delamination
Problems with is primarily present during instrument：
1st, the survey cylinder of roof separation indicator is arranged on back, is not easy to drilling construction and daily observation；2nd, roof delamination amount compared with
When big, survey in the whole retractions drillings of cylinder meeting, separation indicator failure, it is impossible to accurately measure roof delamination amount size；3rd, roof delamination
The anchor head that instrument is used for fixed base point in installation process at the scene is easily overturn during drilling is pushed into, and anchor head is difficult to smoothly arrive
Up to precalculated position, separation indicator install failure is caused；4th, for the tunnel of surface failure of rock, roof separation indicator sleeve is difficult in aperture
It is fixed, cause observation numerical value inaccurate.
The content of the invention
The present invention has that monitoring effect is poor to solve existing tunnel monitor, is not easy to observation construction and installation is more complicated
There is provided a kind of mining tunnel deformation monitoring equipment for problem.
The present invention adopts the following technical scheme that realization：A kind of mining tunnel deformation monitoring equipment, including it is arranged on lane
It is provided with and connects with it between upper fixed seat, lower fixed seat at road top, bottom plate and the basic point being provided with the lane side of both sides, two basic points
The expansion links of about two distributions are provided with the cotton rope connect, lower fixed seat, be provided between two expansion links wear in the inner and with
Its left-right rotary screw rod being threadedly coupled, is provided with spring spool, and pass through lower joint sleeve cylinder spiral shell above the expansion link of upside
Line is connected, and adjustable spring is placed with spring spool, and spring spool upper end is provided with the pre- pressure cap of spring, and upper fixed seat lower end is set
It is equipped with the lengthening extension rod being distributed up and down and the scale bar of adjustable spring is close in lower end, lengthens extension rod and pass through upper company with scale bar
The tuning drive gear and spirit level for pointing to scale bar are provided with female connector cylinder threaded connection, spring spool.
When carrying out roadway deformation monitoring, chosen according to tunnel height and lengthen extension rod, and adjust left-right rotary screw rod to scale
Pointer points to 0 of scale bar, measures cotton rope with the intersection point of scale bar to the distance between two basic points and upper and lower fixed seat, and
Record numerical value, by observing the numerical value change of scale bar, record roof and floor shift-in amount, when tunnel belt in the running, pass through line
Rope coordinates horizon rule, and the record amount of crushing and pucking amount are measured respectively, during tunnelling, record cotton rope and scale bar
The mobile variable quantity of intersection point, to measure the tunnel roof to floor convergence during tunnelling, overcomes existing tunnel monitor and deposits
Monitoring effect it is poor, be not easy to observation construction and install it is more complicated the problem of.
Reasonable in design of the present invention is reliable, it is adaptable to measure the deflection in different height tunnel, has prevented traditional scale
Disk can all stretch into the generation of phenomenon in pipe, and observation and record intuitive and convenient, without the need for construction drill is carried out, install
It is convenient, site operation progress is not influenceed, can be reused.
