The content of the invention
The purpose of this utility model is that setting lock pin anchor manual operation for current three arm rock drilling jumbo causes between drilling
Away from, angle it is unmanageable the problems such as, there is provided a kind of three arm rock drilling jumbo sets the fixing device of lock foot anchoring stock.
To achieve the above object, technical solution of the present utility model is：A kind of three arm rock drilling jumbos set lock pin anchor
The fixing device of bar, include the supporting plate of square structure, described supporting plate is divided into left part and right part, supporting plate
Left part is welded with jack, and the right part of supporting plate offers the circular hole more than outside diameter.
The supporting plate is the steel plate that thickness is more than 2cm.
The left part width of the supporting plate=steelframe flange width/2- steelframe web thickness, the right part of supporting plate
Width=bit diameter+3cm.
Described jack is welded on supporting plate left part center, and described circular hole is opened in right part center.
Described Circularhole diameter=bit diameter+1cm.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is novel, simple in construction, installation, convenient disassembly, reusable.
2nd, abrasion of the drilling rod to the present apparatus is highly resistant to using steel plate in the utility model, improves the present apparatus and use the longevity
Life.
3rd, in use, single assembly extrudes fixation by jack respectively, it is firm to stablize, so as to effectively control artificial behaviour
Make the deviation of three arm rock drilling jumbo drilling rods, make pore-forming angle precision high；So as to solve three arm rock drilling jumbo manual operations drilling
Spacing, the problem of angle is unmanageable.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is that the utility model uses schematic diagram.
In figure, supporting plate 1, jack 2, circular hole 3, steelframe 4.
Embodiment
The utility model is described in further detail below in conjunction with brief description of the drawings and embodiment.
Referring to Fig. 1, a kind of three arm rock drilling jumbo sets the fixing device of lock foot anchoring stock, in constructing tunnel preliminary bracing
Steelframe lock foot anchoring stock is fixed；Supporting plate 1 including square structure.Described supporting plate 1 is divided for left part and right part, branch
The left part of fagging 1 is welded with jack 2, and the right part of supporting plate 1 offers the circular hole 3 slightly larger than outside diameter.
Referring to Fig. 1, the supporting plate 1 is the steel plate that thickness is more than 2cm.
Referring to Fig. 1, left part width=4 flange widths of steelframe/web thickness of 2- steelframes 4 of the supporting plate 1, support
Right part width=bit diameter+3cm of plate 1.
Referring to Fig. 1, the described tube chamber welds with base of jack 2 is opened in the left part center of supporting plate 1, described circular hole 3
Right part center.
Referring to Fig. 1, described 3 diameters of circular hole=bit diameter+1cm, the hole wall of circular hole 3 is away from the outer rim minimum range of supporting plate 1
2cm。
Referring to Fig. 1 to Fig. 2, one group of the present apparatus two is used cooperatively, and the present apparatus is embedded in the edge of a wing groove of steelframe 4 during use,
The left part of supporting plate 1 is bonded with the edge of a wing of steelframe 4 inner side, web respectively close to the web of steelframe 4, the bottom surface of supporting plate 1, outer rim；Top
Enter jack 2, supporting plate 1 is secured firmly in the edge of a wing groove of steelframe 4.Drill bit continues to pass through the circular hole 3 of stream oriented device during construction, leads to
The discrepancy in elevation crossed between two devices of adjustment carrys out the angle of keyhole, so as to solve between three arm rock drilling jumbo manual operations drilling
Away from, angle it is unmanageable the problem of.
Referring to Fig. 1 to Fig. 2, a kind of three arm rock drilling jumbo sets the application method of the fixing device of lock foot anchoring stock, including under
The step of face：Step 1, processing unit (plant)：Supporting plate 1 is processed into using steel plate of the thickness more than 2cm, makes the left side of supporting plate 1
Partial width=4 flange widths of the steelframe/web thickness of 2- steelframes 4, the base of jack 2 is placed in left part center, and welds jail
Lean on；Making right part width=bit diameter+3cm of supporting plate 1, a circular hole 3 is opened at wherein right part center, the diameter of circular hole 3=
Bit diameter+1cm, the hole wall of circular hole 3 are 2cm away from the outer rim minimum range of supporting plate 1.
Step 2, device installation：According to design height, a fixing device is installed on steelframe 4, steelframe 4 is fixed on and leans on
The side wing edge of tunnel center one；Then according to lock pin design be drilled with the discrepancy in elevation of two fixing devices of angle calculation=（The web of steelframe 4 is high
The edge of a wing thickness * 2-2*2 of degree-steelframe 4）*tan（It is drilled with angle）, then another fixing device is installed.
Step 3, drilling：Three arm rock drilling jumbo mechanical arms are operated, allow drill bit to sequentially pass through the circular hole 3 of two fixing devices
Drilled, until projected depth.
Step 4, remove device：After drilling is completed, drill bit exits, the jack 2 of two fixing devices is shunk, by fixation
