Description
Technical field
The present invention relates to a kind of anchors, belong to mooring rod technique field.
Background technique
It is built in tunnel and other underground installation processs of construction in mining, rock, needs to add rock top, palisades etc.
Gu, to prevent massif part as the time can cave in, people have developed a variety of different types to prevent from collapsing or be recorded
Reinforcing massif device and technique.
Some rock-bolt installations, which are usually required that using drilling machine and drill steel, drills out drilling, and drill steel is then moved from drilling
Out, then cement slurry is poured into drilling, subsequent rock-bolt itself is inserted into and is fastened in face of backing plate, and rock-bolt is installed
It is conventional containing bore it is rigid pierce and to take out step relatively time consuming, in the case where mining site operates efficient background, rock-bolt is installed, its requirement
Many independent tasks for needing time and a large amount of manpowers, such as：Fixed drill steel drills out drilling, removes drill steel, pours into resin and insertion
Rock-bolt, fixed rock-bolt, install conventional steps all versus busies of rock-bolt.
Some rock-bolts are used separately with anchor mechanism, and anchor mechanism cannot be operated after rock-bolt is inserted into,
Rock-bolt cannot effectively be fixed；Part rock-bolt usually merges a part or connection of drill bit as rock-bolt head end
To rock-bolt head end, tail end is connected to drilling machine to drill out drilling, once hole is drilled, rock-bolt is remained in hole, though
The right rock-bolt has advantage on implementing speed, but cement grouting is very difficult, and pre- without any anchor mechanism
It first takes steps to effectively fix rock-bolt.
Summary of the invention
It is an object of the invention to：One kind is provided from anchoring rod, to solve the disadvantage that existing rock-bolt exists.
To solve the above problems, proposed adoption is such a from anchoring rod, including it is gag lever post, stress item, guide pin, hollow
Anchor pole and push rod offer through-hole on the side wall of hollow anchor bar, and through-hole is angularly disposed, and one end via through holes of gag lever post extend to hollow
In anchor pole, stress item is set in hollow anchor bar along the length direction of hollow anchor bar, and one end of stress item is articulated with hollow anchor
On the inner wall of bar, the other end is fixedly connected with one end of guide pin, and the other end of guide pin is adjacent to the inner wall setting of hollow anchor bar,
And reserve and have the gap between stress item and the inner wall of hollow anchor bar, the push rod extends to hollow anchor bar by the tail end of hollow anchor bar
It is interior；
It is aforementioned from anchoring rod, the through-hole is oblique hole, and through-hole inclines towards the tail end of hollow anchor bar from inside to outside
Tiltedly setting；
It is aforementioned from anchoring rod, the diameter of push rod is the 7/10-9/10 of hollow anchor bar internal diameter, and the head end of push rod is inclined
Flat structure.
Compared with prior art, the present invention provides the anchor pole that one kind is capable of mechanical anchor, rock can effectively be fixed
Anchor pole can drive well mechanical anchoring device to anchor to rock-bolt, increase anchor support ability, reduce
Many and diverse construction procedure, shortens the construction time, which has good promotion and practical value, meeting after extensive popularization and application
Generate good economic benefit and social benefit.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram under use state.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
The detailed description of step, it should be understood that described herein specific examples are only used to explain the present invention, is not used to limit this hair
It is bright.
Embodiment：
Referring to Figures 1 and 2, the present embodiment provides one kind from anchoring rod, including gag lever post 1, stress item 2, guide pin 3,
Hollow anchor bar 4 and push rod 5 offer through-hole 41 on the side wall of hollow anchor bar 4, and through-hole 41 is oblique hole, and through-hole 41 is by introversion
The outer tail end towards hollow anchor bar 4 is obliquely installed, and one end via through holes 41 of gag lever post 1 extend in hollow anchor bar 4,2 edge of stress item
The length direction of hollow anchor bar 4 is set in hollow anchor bar 4, and one end of stress item 2 is articulated on the inner wall of hollow anchor bar 4,
The other end is fixedly connected with one end of guide pin 3, and the other end of guide pin 3 is adjacent to the inner wall setting of hollow anchor bar 4, and stress item
It reserves and has the gap between 2 and the inner wall of hollow anchor bar 4, the push rod 5 is extended in hollow anchor bar 4 by the tail end of hollow anchor bar 4, is pushed away
The diameter of bar 5 is the 7/10-9/10 of 4 internal diameter of hollow anchor bar, and the head end of push rod 5 is inclined flat structure.
The application method of above-mentioned anchor pole is as follows：
Drilling machine is taken, the output end of drilling machine is connected with the tail end of hollow anchor bar 4 using spanner, hollow anchor is driven by drilling machine
Bar 4 is to pierce rock or soil layer, after piercing, removes drilling machine, and push rod 5 is stretched to hollow anchor bar 4 by the tail end of hollow anchor bar 4
It is interior, and push guiding role of the push rod 5 through guide pin 3 stress item 2 to the direction far from 4 center line of hollow anchor bar, stress
It drives during being moved outside item 2 and is moved outside the gag lever post 1 on the outside of it, 1 via through holes 41 of gag lever post extend out to the outside of hollow anchor bar 4 simultaneously
It is anchored in rock or soil layer, realizes the anchoring of anchor pole.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
