Abstract
The utility model discloses a kind of new multistage pressure-relieving achor bar, including anchor bar body, switch base plate, small raft, pallet, pressure ring is allowed, allow pressure ball, nut.Two pieces of backing plates of size are installed on anchor rod body; it is sequentially provided with the outside of switch base plate and allows pressure ring and allow pressure ball with through hole; allow pressure ball to be made up of rubber, allow pressure ball to be inscribed within and allow pressure ring, allow pressure ring to be externally provided with pallet; nut is located at the outside of small raft; so constitute a multistage pressure-relieving achor bar, the utility model can realize that multistage allows pressure, when tunnel generation moderate finite deformation; anchor pole can be protected to avoid being pulled off, with it is safe and reliable, simple and convenient the characteristics of.
Description
Technical field
The utility model is related to a kind of new multistage pressure-relieving achor bar, belongs to timbering technology in coal mine field.
Background technology
In recent years, China's shallow embedding coal preservation scarcity of resources, the continuous increase of mining depth, crustal stress is dramatically increased, lane
Road surrouding rock stress increases, and roadway deformation amount is larger.Deep tunnel requires that anchor pole has certain pressure energy power and enough intensity of allowing.
Common bolt is smaller by pressure energy power, it is impossible to meet the larger mine of deformation of the surrounding rock in tunnel, therefore, need to provide a kind of new pressure anchor that allows
Bar.
The content of the invention
There is provided a kind of new multistage pressure-relieving achor bar for above-mentioned the deficiencies in the prior art for the utility model.
The technical scheme that the utility model solves the above problems is：A kind of new multistage pressure-relieving achor bar, including anchor bar body, greatly
Backing plate, small raft, pallet allows pressure ring, allows pressure ball, nut, and the new multistage pressure-relieving achor bar, is installed on anchor rod body
Two pieces of backing plates of size, are sequentially provided with the outside of switch base plate and allow pressure ring and allow pressure ball with through hole, allow pressure ball to be made up of rubber, allow pressure
Ball, which is inscribed within, allows pressure ring, allows pressure ring to be externally provided with pallet, and nut is located at the outside of small raft, nut and allows between pressure ring and is provided with pulvinulus
Plate, so constitutes a multistage pressure-relieving achor bar.
Described to allow pressure ball to be provided with through hole in a kind of above-mentioned new multistage pressure-relieving achor bar, anchor rod body can be through whole
Allow pressure ball.
It is described to make pressure ring flexible in a kind of above-mentioned new multistage pressure-relieving achor bar, high-strength metal material system need to be used
Into.
The beneficial effects of the utility model are, due to using above-mentioned technical proposal, when moderate finite deformation occurs for roadway surrounding rock,
Flexible allows pressure ring to occur ductile deformation, when roadway surrounding rock continues to deform, and allows pressure ball to continue hair
Raw deformation, makes anchor pole not be pulled off, and continues have bearing capacity, and the effective supported laneway of energy safeguards stability of the roadway.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is principle schematic diagram of the present utility model.
In Fig. 1,1. switch base plates, 2. pallets, 3. allow pressure ring, 4. to allow pressure ball, 5. anchor rod bodies, 6. small rafts, 7. nuts.
