Abstract
The utility model relates to an anchor rod tension force detection and pre-tightened integration device which comprises a tension force gauge and a support base, the tension force gauge can be sleeved on an anchor rod body, and a hollow piston column body of the tension force gauge aligns at the top wall of the support base, the support base is a hollow sleeve structure, a rod body through hole is machined in the top wall of the support base, and a wrench movable hole is machined in the side wall of the support base. The wrench movable hole is formed in the side wall of the support base, and an opening thickening pad is arranged between the support base and the hollow piston column body of the tension force gauge. When an anchor rod is pre-tightened and a nut at the tail end of the anchor rod is loosened, a wrench can directly rotate the nut by the wrench movable hole, and enables the anchor rod to be pre-tightened. A pre-tightening force value is displayed on a pressure gauge of the anchor rod tension force gauge, the anchor rod can be continued to be pulled after the nut is fastened, and the nut is fastened again until the pre-tightening force is reached. When the stroke of the hollow piston column body of the anchor rod tension force gauge is not enough, the opening thickening pad is increased or decreased to fill the stroke of the hollow piston column body of the tension force gauge.
Description
Technical field
The utility model belongs to mining engineering and field of civil engineering, concrete a kind of integrating device that is applicable to axis force of anchor detection and pretension.
Background technology
It is to improve the effective ways of Effects of Supporting that anchor pole is applied enough pretightning forces.But often because resistance is larger, depends merely on spanner or jumbolter and be difficult to reach required pretightning force, therefore need to carry out pretension to anchor pole by means of pre-tightening apparatus.
At present, pre-tension method commonly used is that the body of rod with anchor pole passes hollow sleeve and extends in the device that can strain anchor pole, the body of rod of device drawing bolt by the tension anchor pole, stretch into the nut loosening on the body of rod in the cannulated sleeve this moment, cannulated sleeve need to be removed, with nut tightening, load onto cannulated sleeve with spanner, repeat pretension, until reach needed pretightning force.This pre-tension method exists the cannulated sleeve dismounting loaded down with trivial details, inconvenient problem with use.Can carry out pretension by a kind of anchor pole preloader of special use in addition, need special-purpose draw-off gear, drive nut rotation with the handle rotational sleeve during pretension, this preloader can solve the problem of the handle rotation space deficiency that causes because of roadway deformation, but its structure is complicated.
The utility model content
In order to solve the existing problem of anchor rod pretightening device in the prior art, the utility model provides a kind of axis force of anchor to detect and the precompact set apparatus for converting, can be implemented in detection axis force of anchor process anchor pole is implemented pretension.
The technical scheme of the utility model technical solution problem is: described axis force of anchor detects with the precompact set apparatus for converting and comprises tensiometer, the supporting seat that can be enclosed within on the anchor rod body, the hollow piston cylinder of tensiometer is over against the roof of supporting seat, supporting seat is the hollow sleeve structure, roof at supporting seat is processed with body of rod through hole, it is characterized in that: the sidewall at supporting seat is processed with the spanner movable span.
At least one opening thickening pad is installed between the hollow piston cylinder of the roof of above-mentioned supporting seat and tensiometer, and the opening thickening pad is the solid cylinder with the opening groove.
Above-mentioned opening thickening pad is 2 ~ 4, can also suitably increase and decrease according to the physical length of the body of rod.
The utility model takes full advantage of the drawing function of rockbolt tension meter, in detection axis force of anchor process anchor pole is implemented pretension, by offering the spanner movable span at the sidewall of supporting seat, between the hollow piston cylinder of supporting seat and tensiometer, also the opening thickening pad can be set, when the pretension anchor pole during loose nut of anchor pole end, spanner can directly pass through this movable span rotating nut, make anchor pole be able to pretension, pretightning force numerical value is presented on the pressure meter of rockbolt tension meter, can continue drawing bolt behind the fastening nuts, clamp nut again is until reach required pretightning force.When the hollow piston cylinder stroke of rockbolt tension meter is inadequate, replenish hollow piston cylinder stroke by increase and decrease opening thickening pad.The utility model is simple in structure, and is easy to operate.
