Description
Technical field
The utility model is related to Detection of Bolt Bonding Integrity detection device, especially a kind of anchor rod drawing instrument during roadway surrounding rock is reinforced
Connector.
Background technology
The connection method often taken in the past has two kinds：One kind is by being welded to connect anchor when checking and accepting in anchor pole end
Bar, and anchorage connection, but this method is complicated, needs man-hour long during examination, and also anchor pole is disconnected easily in weld bond position when examining
Open；Another is to reserve a number of anchor pole before detecting, exposed junction length is more than or equal to during this part rockbolt installation
300mm, convenient operation during to be detected, this method, which is easily caused, it is known to which anchor pole, construction detected in advance
The installation quality of these anchor poles targetedly improves in side when installing anchor pole, so detection data are just without representativeness.
The content of the invention
To overcome the shortcomings of that above two connection method is present, the utility model is connected there is provided a kind of anchor rod drawing instrument
Device, end can not be stayed sufficient length or the shorter anchor pole of length in reserve and drawing instrument effectively to connect, anchored
Power is detected.
Above-mentioned purpose is achieved through the following technical solutions：A kind of anchor rod drawing instrument connector is by connecting tube, capstan A, drawing
Solenoid B, clamp nut, drawing backing plate, connecting rod, support base, packing ring composition.
The connecting tube is high strength alloy steel, the equidistant use helicitic texture in two ends.
The capstan is hollow tube, and hollow section shape size is different, and capstan is away from hollow section in the range of one end 1/4
For circle, twice of a diameter of bolt diameter, inwall uses helicitic texture, and capstan is away from hollow section in the range of the other end 1/4
For circle, 1.1 times of a diameter of anchor rod body, capstan middle part is that hollow section is regular hexagon, regular hexagon circumscribed circle
Diameter is more than the external diameter of a circle of clamp nut, and capstan A, capstan B are located at the two ends of connecting tube, be linked to be by connecting tube respectively
One.
The drawing backing plate is high-strength steel sheet, and center is provided with manhole, and through-hole diameter is two kinds, a kind of through-hole diameter
More than anchor rod body diameter, less than pulling force pipe diameter, another through-hole diameter is more than pulling force pipe diameter and is less than support base diameter.
The connecting rod is a kind of high-strength deformed steel bar, using and experiment anchor pole identical helicitic texture.
The support base is hollow housing, using high-strength steel sheet, highly more than connecting tube, capstan A and capstan B length
Sum is spent, cross section diameter is more than drawing backing plate central through hole diameter.
The packing ring is located between clamp nut and capstan.
The beneficial effects of the utility model are, can be effective when anchor pole exposed junction does not stay length or shorter length in reserve
Ground connects anchor pole and drawing instrument and carries out anchor rod drawing experiment.
Brief description of the drawings
The utility model is related to Detection of Bolt Bonding Integrity detection device, especially a kind of anchor rod drawing instrument during roadway surrounding rock is reinforced
Connector.The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is to apply pull-out test structural representation of the present utility model.
Fig. 2 is to apply pull-out test sectional view of the present utility model.
Fig. 3 is the utility model enlarged drawing.
Fig. 4 is the utility model structure chart.
In figure：1st, anchor pole is tested, 2, drawing backing plate, 3, capstan A, 4, connecting tube, 5, capstan B, 6, support base, 7,
Connecting rod, 8, drawing hollow hydraulic oil cylinder, 9, clamp nut, 10, packing ring.
Embodiment
As illustrated, a kind of drawing instrument connector includes, connecting tube 4, capstan A3, capstan B5, clamp nut 9, drawing
Pull out backing plate 2, connecting rod 7, support base 6, packing ring 10.Connection rod outer surface uses helicitic texture.Capstan A3's and capstan B5
Each one end inner surface uses helicitic texture, and experiment anchor pole 1 enters from capstan A3 non-threadeds one end, and spiral shell is passed through with clamp nut 9
Line coordinates.The one end of connecting rod 7 is passed through from hollow hydraulic jack 8, is coordinated with clamp nut 9 by screw thread and fixed, and the other end is from drawing
Solenoid B5 non-threadeds one end enters, and is coordinated with clamp nut 9 by screw thread.Capstan A3 and capstan B5 and connecting tube are all used
Screw thread coordinates.Packing ring 10 is close to clamp nut 9 and capstan A3, capstan B5.Drawing backing plate 2 is of different sizes due to central through hole
It is divided to two kinds, a kind of central through hole allows anchor pole to pass through, another central through hole allows capstan A3 to pass through.
When carrying out anchor rod drawing experiment, the experiment exposed junction of the body of rod 1 is fastened on one by clamp nut 9 and capstan A3
Rise, connecting rod 7 is respectively linked together hollow hydraulic oil cylinder 8 and capstan B5 by clamp nut, last connecting tube will be drawn
Solenoid A3 and capstan B5 link into an integrated entity.When hollow hydraulic jack 8 carries out pressurization drawing, hollow hydraulic oil cylinder 8 is fixed on
On connecting rod tense be located at capstan B5 in clamp nut 9, pass through the extruding between clamp nut 9 and capstan B5 and company
The connection function of adapter 4, the experiment anchor pole 1 being fixed on capstan A3 is equally tightened up.If testing the exposed junction mistake of anchor pole 1
Hour, the depth of 1/2 capstan A3 length will be cut around anchor pole, use the big drawing backing plate 2 of central through hole, capstan A3 instead
It can be attached into rock mass, now can further pressurize carry out pull-out test.
The utility model, can be effectively by anchor pole when anchor pole exposed junction does not stay sufficient length or shorter length in reserve
Connected with drawing instrument, carry out pull-out test, obtain effective test data, improve the supporting quality in tunnel, it is ensured that tunnel
It is stable.
