Description
Technical field：
The present invention relates to anchor pole interconnection technique fields, and in particular to a kind of plastic anchor rod connector of expansion chuck.
Background technology：
In mine underground roadway bolting support system, anchor pole is as main support pattern.Pallet is anchor rod device equipment
In an important component.After anchor pole applies pretightning force, anchor nut is concentrated force to power caused by the surface of country rock tunnel,
The effect of constraint surrouding rock deformation can be played immediately.Therefore there is the problems such as yielding, fastening force is not strong mostly in existing anchor rod pallet board,
Easily country rock is made to rupture, supporting intensity reduces in Bracing Process, anchor pole is broken so as to cause anchor pole so that suspension roof support is failed.
The present invention transmits load and protection anchor pole end using the plastic anchor rod connector of expansion chuck to realize.Work as surrouding rock deformation
So that load is acted on instrument, anchor rod body is transferred loads to by instrument, increases the working resistance of anchor pole, give full play to anchor
The effect of bar deformation controlling for rock surrounding gateways.The plastic anchor rod connector of expansion chuck not only makes termination point of anchor rod load be uniformly distributed stress, but also
Also expand and transmit load range, enhances enclasping force, substantially increase the reliability of supporting.
Invention content：
The object of the present invention is to provide a kind of plastic anchor rod connector of expansion chuck, by the effect of high strength tension bolt,
Huge enclasping force is generated between inner sheath and anchor pole, between oversheath and country rock, to realize that the fastening of anchor pole and connector is imitated
Fruit.
To achieve the above object, the present invention uses following technical scheme：
The plastic anchor rod connector of expansion chuck provided by the invention, including inner sheath and oversheath, the inner sheath include the
One cylindrical member, towards the first extension is extended to form outside the first cylindrical member, described first prolongs for the outer wall of first cylindrical member
The end of extending portion extends to form the second extension along being parallel to first cylindrical member central axes direction, first extension and
Forming toroidal cavity between second extension and first cylindrical member, the oversheath includes the second cylindrical member, and described second
Cylindrical member is sheathed on the first cylindrical member outer wall, is extended to form outside outer wall the second cylindrical member of direction of second cylindrical member
Third extension, the third extension are flush-mounted in the toroidal cavity, and bolt is fitted on the inner sheath and oversheath,
The inner sheath and oversheath are held together.
Bolt slot is respectively arranged on first extension and third extension, the bolt is plugged in the bolt
On slot, first extension and third extension is made to be linked as entirety.
The outer wall of first cylindrical member is set as the first inclined-plane, and the inner wall of second cylindrical member is set as second tiltedly
The angle of inclination on face, first inclined-plane and the second inclined-plane is identical.
There are gaps before with first extension for the third extension.
The advantageous effect of the plastic anchor rod connector of expansion chuck of the present invention：It can be used for mine engineering, Tunnel Engineering, water conservancy and contains
The anchor rod device of hole supporting, suitable for surrounding rock deformability is strong, and service life is long, intensity is high, later stage large carrying capacity, and can protect
Termination point of anchor rod damage is protected, by frictional force, has certain stroke, expansion coupling reliable and stable；Pass through high strength tension bolt
Effect, huge enclasping force is generated between inner sheath and anchor pole, between oversheath and country rock, to realize anchor pole and connector
Fastening effect, when bearing pulling capacity, by connector and anchor pole, the combination pressure of country rock and the frictional force transmission axle generated together
To power and axial load；Simple in structure, cost of manufacture is relatively low, install convenient, simple, and fastening effect is good, convenient disassembly, and has
Good interchangeability.The anchor pole of larger fit clearance can be combined, when dismounting unscrews bolt, you can make to be coupled part appearance
It easily dismantles, when swelling, the close not corrosion easy to attach of contact surface also allows for dismantling.When instrument is when more than a constant load, Ke Yibao
It is without damage to protect anchor pole.
