Abstract
The utility model discloses a novel yielding bolt. The utility model discloses a body of rod, nut, tray, two bilayers let clamping ring and big, little backing plate, and body of rod afterbody is fixed through little backing plate and nut, and the cover has a tray between big, the little backing plate, and the tray has two bilayers let the clamping ring with overlapping greatly between the backing plate. Should let and press the stock can in time provide strutting of large intensity more when mine tunnel's surrouding rock deformation proruption, use safelyr.
Description
Technical field
The utility model relates to a kind of mining equipment, specifically a kind of novel pressure-relieving achor bar.
Background technology
In underground engineering field such as mines, it is essential to supporting roadway surrounding rock. Field, mine increases year by year along with mining depth, and terrestrial stress also significantly increases, and roadway surrounding rock stress increases, and at deep tunnel, wall rock geology presents soft rock characteristic, and tunnel distortion is big, and roadway support is difficult.
Anchor pole is installed in bolt supporting in roadway surrounding rock, reinforces coal and rock so that it is have from steady and supporting capacity, keeps a kind of initiatively supporting way of Drift stability. But common anchor pole unit elongation is not enough, after extending, the feature such as decrease in intensity causes meeting the resistance of existing deep mining coal and rock supporting height and allows pressure and shock proof requirement.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of novel pressure-relieving achor bar, and this pressure-relieving achor bar can provide the supporting of greater strength in time when the country rock distortion burst of mine laneway, it may also be useful to safer.
This technical scheme using the technical problem of novel solution to adopt is:
A kind of novel pressure-relieving achor bar, mainly comprises the body of rod, nut, pallet, two bilayers allow pressure ring and large and small backing plate, and body of rod afterbody is fixed by small raft and nut, and between large and small backing plate, cover has pallet, and between pallet and switch base plate, cover has two bilayers allow pressure ring.
Being provided with a ring-shaped baffle in the middle part of the described body of rod, ring-shaped baffle and the body of rod are integrated.
Two described bilayers allow pressure ring centre be separated by body of rod baffle plate.
Described bilayer allows pressure ring upper/lower terminal opening, opening shape be circular in order to be inserted in the body of rod.
Described bilayer allows pressure ring be inside and outside two to have elastic metal sheet, and outer shroud is spherical, and inner ring is rugby shape, and inner and outer rings connects as one structure at upper/lower terminal.
Compared with prior art, the utility model has the following advantages:
Two bilayers allow pressure ring have elasticity, can be out of shape according to by power size generation extensibility, it is achieved allow compression functions. Anchor pole is when being subject to impacting, it is possible to realizes the gross distortion (being no more than the maximum distortion of anchor pole) of moment and does not destroy the one-piece construction of anchor pole, makes anchor pole still have supporting capacity, thus realize shock resistance effect.
Cost is low, makes simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is the body of rod, 2 is nut, and 3 is small raft, and 4 is pallet, and 5 is switch base plate, and 6 allow pressure ring for bilayer, and 7 is baffle plate.
Embodiment
During installation, first it is inserted in switch base plate 5 and a bilayer allows pressure ring 6 at the head of the body of rod 1, then the body of rod 1 is anchored in the boring on country rock, pressure ring 6, pallet 4, small raft 3 is allowed to be inserted in the afterbody of the body of rod 1 respectively a bilayer again, finally with nut 2, the body of rod 1 is fastened and fixed, making switch base plate 5 be close between country rock and each integral part to be in close contact, last tension is to regulation preliminary tension.
