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：A kind of mechanical anchoring device is provided, to solve the disadvantage that existing rock-bolt exists.
To solve the above problems, such a mechanical anchoring device of proposed adoption, including fixed awl, stress item, crisp matter branch
Blade, guide pin and hollow anchor bar, through-hole is offered on the side wall of hollow anchor bar, and fixed awl via through holes extend to hollow anchor bar
Interior, stress item is set in hollow anchor bar along the length direction of hollow anchor bar, and stress is fixed in the crisp matter support chip support
Between item and the inner wall of hollow anchor bar, had the gap so that being reserved between stress item and the inner wall of hollow anchor bar, the guide pin
One end be fixedly connected with one end of stress item, the other end of guide pin be adjacent to hollow anchor bar inner wall setting, hollow anchor bar is also
It is correspondingly arranged on the driving push rod that can be extended in hollow anchor bar.
In aforementioned mechanical anchor, the other end of the guide pin is fixed on the inner wall of hollow anchor bar, fixation side
Formula can be to be bonded or welded.
In aforementioned mechanical anchor, the stress item altogether there are two, two stress items are arranged in parallel in hollow anchor bar,
One end of the driving push rod is flat mouth structure, and the flat mouth end of driving push rod extends between two stress items through guide pin.
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 the structural schematic diagram of hollow anchor bar of the present invention and mechanical anchoring device thereon；
Fig. 2 is the structural schematic diagram under the mechanical anchoring device 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 a kind of mechanical anchoring devices, including fixed awl 1, stress item 2, crisp matter
Support chip 3, guide pin 4 and hollow anchor bar 5, through-hole 51 is offered on the side wall of hollow anchor bar 5, and fixed 1 via through holes 51 of awl are stretched
To hollow anchor bar 5, stress item 2 is set in hollow anchor bar 5 along the length direction of hollow anchor bar 5, and the crisp matter support chip 3
Support is fixed between stress item 2 and the inner wall of hollow anchor bar 5, so that reserving between stress item 2 and the inner wall of hollow anchor bar 5
It has the gap, one end of the guide pin 4 is fixedly connected with one end of stress item 2, and the other end of guide pin 4 is fixed on hollow anchor bar
On 5 inner wall, fixed form can be to be bonded or welded, and hollow anchor bar 5, which is also correspondingly arranged on, can extend in hollow anchor bar 5
Driving push rod 6, the stress item 2 altogether there are two, two stress items 2 are arranged in parallel in hollow anchor bar 5, the driving push rod 6
One end be flat mouth structure, and the flat mouth end of driving push rod 6 extends between two stress items 2 through guide pin 4.
The application method of above-mentioned mechanical anchoring device is as follows：
Drilling machine is taken, the output end of drilling machine is connected with the tail end of hollow anchor bar 5 using spanner, hollow anchor is driven by drilling machine
Bar 5 is to pierce rock or soil layer, after piercing, removes drilling machine, and driving push rod 6 is stretched to hollow anchor by the tail end of hollow anchor bar 5
In bar 5, and push away guiding role of the driving push rod 6 through guide pin 4 stress item 2 to the direction far from 5 center line of hollow anchor bar
Dynamic, crisp matter support chip 3 is crushed under the pressure effect that driving push rod 6 applies, and is driven on the outside of it during moving outside stress item 2
It is moved outside fixed awl 1, fixed 1 via through holes 51 of awl extend out to the outside of hollow anchor bar 5 and are anchored in rock or soil layer, realize
The mechanical 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.
