Summary of the invention
For above-mentioned situation, for solving the defect of prior art, the purpose of this utility model is just to provide a kind of laboratory anchor rod drawing test pulling capacity displacement monitor, can effectively solve the accurate monitoring problem of anchor rod drawing test pulling capacity displacement in laboratory.
Solution of the present utility model is, including anchorage, hollow ball shape disc, pressure transducer, punching jack, displacement transducer, hydraulic hand-pump, punching jack is through anchoring on the anchor pole in boring in advance, pressure transducer, hollow ball shape disc, anchorage it is sequentially placed on punching jack, hydraulic hand-pump oil pipe is connected with punching jack, pressure transducer is connected with computer, displacement transducer gauge head bearing is fixed on pressure transducer, displacement transducer is fixed on laboratory floor, then is connected with computer by displacement transducer.
This utility model simple in construction, easy to operate, efficiently solve the relations problems of laboratory anchor rod drawing test pulling capacity and displacement, measured by precision instrument and computer detection, ensure that higher certainty of measurement, be conducive to preferably the stress of anchor pole being detected, provide more preferable design considerations for coal mine roadway suspension roof support, be the innovation on laboratory anchor rod drawing assay device.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Be given by Fig. 1-3, this utility model includes anchorage, hollow ball shape disc, pressure transducer, punching jack, displacement transducer, hydraulic hand-pump, punching jack 1 is through the anchor pole 9 anchoring into boring in advance, then anchor pole 9 placement force sensor 2 is sequentially passed through, hollow ball shape disc 3, anchorage 4, hydraulic hand-pump oil pipe 16 is connected with punching jack 1, pressure transducer 2 is connected with computer by first line 14, displacement transducer gauge head bearing 7 is fixed on pressure transducer 2, displacement transducer 6 is fixed on laboratory floor, and displacement transducer 6 is connected with computer by the second circuit 15.
In order to ensure using effect, described punching hydraulic jack 1 maximal dilation amount is 60mm, meets laboratory anchor rod drawing test requirements document.
Described anchorage 4 is made up of two identical parts, it is combined together by the bolt 11 of both sides, nut 12, its centre bore is combined with tapered ring-type fixture 10, anchorage 4 after combination is in hollow cylindrical, its lower end spherically body, mates guarantee stress equalization, anchorage 4 upper end overall diameter 80mm with the spherical groove of hollow ball shape disc 3, upper end interior diameter 32mm, high 96mm.
Described displacement transducer 6, for displacement sensor for pull rope, maximum range is 1.5 meters, and by steel wire rope 13 and the anchor pole keeping parallelism of displacement transducer during test, the data of displacement transducer are input to computer end by the second circuit 15, and automatically draw displacement changing curve.
Described pressure transducer 2, for punching pressure transducer, sensor internal have recorded calibration value parameter, can fast recording measurement data, and be transported to computer show by outfan first line 14, degree of accuracy is higher.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model know-why; can also make some improvement and replacement, these improve and replace and also should be regarded as protection domain of the present utility model.
Service condition of the present utility model is, uses similar materials to carry out preparing block 8, after block 8 reaches design strength, hole in laboratory, and boring stops boring after reaching projected depth, puts into Anchor Agent and anchor pole 9 anchors；After having anchored, punching hydraulic jack 1 is placed on block 8 through anchor pole, being placed upward by jack telescopic end, then pressure transducer 2, disc 3 anchorage 4 sequentially pass through anchor pole and are placed in punching hydraulic jack, are connected with punching jack 1 by hydraulic hand-pump oil pipe 16；The gauge head bearing 7 of displacement transducer is fixed on pressure transducer 2 by magnetic-adsorption effect, displacement transducer 6 is placed on the floor of laboratory, and ensure that steel wire rope 13 is parallel with anchor pole 9, and pressure transducer 2 and displacement transducer 6 are attached with computer respectively.After apparatus above has connected, manually hydraulic pump 5 provides oil pressure to punching hydraulic jack 1, now the telescopic end of hydraulic jack starts to produce overhang, squeeze pressure sensor 2, the computer synchronous recording that is connected with pressure transducer 2 and displacement transducer 6 data of the two, processed by data therebetween, anchor pole pulling capacity displacement curve in pull-out test can be drawn out the most accurately.After pull-out test completes for the first time, preserve the data on computer, then opening the oil return valve of hydraulic hand-pump 5, now the oil return pipe of the manually hydraulic pump 5 of the hydraulic oil in punching jack 1 returns hydraulic hand-pump 5, and the telescopic end of punching jack 1 starts the release that bounces back.The displacement of pull-out test for the first time can be made up according to the interpolation cushion block between punching hydraulic jack 1 and test block 8 that needs of test simultaneously, implement the test of secondary anchor rod drawing.
