Abstract
The utility model relates to an anchor rod construction angle controller, including the protractor, its characteristics are that the straight line limit of protractor is connected perpendicularly with the middle part of a rectangle flitch upper surface, and a diameter slightly is greater than the round hole of stock diameter is opened at the middle part one side on the straight line limit of protractor to the flitch, and a couple, protractor and flitch overall construction are respectively established at the both ends of the lower surface of flitch. Has the advantages that: the anchor rod supporting device is low in cost and simple to operate, accuracy of anchor rod construction angles is improved, and anchor rod supporting quality is improved.
Description
Technical Field
The utility model relates to a coal mine tunnel construction field, more specifically the stock construction angle controller that says so.
Background
The anchor rod is usually beaten in the construction of colliery underworkings and is strutted, and nevertheless anchor rod construction angle control is crucial to the anchor rod support effect, requires the perpendicular tunnel contour line tangent line of anchor rod among the national standard, and in actual anchor rod work progress, anchor rod angle control is comparatively difficult, and the unqualified phenomenon of ubiquitous anchor rod construction angle has seriously influenced the tunnel support effect.
Disclosure of Invention
The utility model aims at overcoming prior art's weak point and providing an anchor rod construction angle controller who improves the anchor rod construction angle degree of accuracy, reinforcing tunnel support effect.
The purpose of the utility model can be realized by the following method: the anchor rod construction angle controller comprises an angle gauge and is characterized in that the linear edge of the angle gauge is vertically connected with the middle of the upper surface of a rectangular flitch, one side of the flitch in the middle of the linear edge of the angle gauge is provided with a round hole with the diameter slightly larger than that of an anchor rod, two ends of the lower surface of the flitch are respectively provided with a hook, and the angle gauge and the flitch are integrally constructed.
Compared with the prior art, the utility model following advantage has: the anchor rod supporting device is low in cost and simple to operate, accuracy of anchor rod construction angles is improved, and anchor rod supporting quality is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a protractor; 2. pasting a board; 3. a circular hole; 4. and (4) hanging hooks.
Detailed Description
With reference to the accompanying drawings as follows: the anchor rod construction angle controller comprises an angle gauge 1 and is characterized in that a straight line edge of the angle gauge 1 is vertically connected with the middle of the upper surface of a rectangular flitch 2, one side of the flitch 2 in the middle of the straight line edge of the angle gauge 1 is provided with a round hole 3 with the diameter slightly larger than that of an anchor rod, two ends of the lower surface of the flitch are respectively provided with a hook 4, and the angle gauge 1 and the flitch 2 are integrally constructed.
When the colliery underworkings construction stock, earlier the utility model discloses 2 lower surface couples 4 of flitch hang on tunnel roof screen, and make flitch 2 go up round hole 3 and the coincidence of anchor rod position of being under construction in advance through adjusting 4 positions of couple, then pass round hole 3 with the drilling rod of the anchor rod of being under construction, through adjusting the rig position and through observing 1 drilling rods that make the construction stock of protractor and 2 perpendicular with flitch, the drilling rod of the anchor rod of being under construction this moment is perpendicular to tunnel contour line tangent line, then start the rig and drive drilling rod construction stock, at this moment the anchor rod construction angle accords with the national standard requirement, the utility model discloses play the effect of control anchor rod construction angle, improved the tunnel and strutted the effect, and the utility model discloses low cost, easy operation, easily manufacturing.
