Abstract
The utility model discloses a kind of recyclable pressure-relieving achor bars, belong to mine support field.Including main rod body 1 and casing 7, main rod body 1 is connected through a screw thread with casing 7, and anchor recovering, 1 exposed junction of main rod body is convenient for be carved with screw thread.Pressing spring 5 is allowed to be placed between flanged plate 6 and wedge shape hoop pad 4, pass through the small-scale deformation occurred suddenly for allowing pressing spring 5 that anchor pole can be made to bear country rock, flanged plate 6 is fitted closely with lane wall, wedge shape hoop pad 4 is sleeved on the exposed junction of main rod body 1, and the upper endless metal gasket 3 of pad on the outside of wedge shape hoop pad, and fastened by hex nut 2.Simply, there is certain allowing to press effect, and recycle conveniently for the roof bolting machine of mating mainstream, greatly reduce roadway support cost for the utility model installation, and for techno-economic effect than more significant, application value is high.
Description
Technical field
The utility model belongs to colliery tunnel support field, is related to a kind of recyclable pressure-relieving achor bar.
Background technology
With the exploitation of coal, the maturation of bolt support technology, performer is increasingly in terms of roadway support for suspension roof support
The application of important role, suspension roof support are also more universal.But in suspension roof support at this stage, after working face pushes through,
Anchor pole is permanent to have stayed in goaf, and recovery utilization rate is very low, meanwhile, when coalcutter works to tunnel exploiting field lateral edges, adopt
Area's lateral wall anchor pole influences whether the normal work of coalcutter, be easy to cause the damage of cutterhead, not only influences normal production operation,
Also production cost can largely be increased；On the other hand, anchor pole upkeep operation space it is safe when, it is of short duration to encounter country rock
And violent deformation, many anchor poles can crumble.Therefore, in order to make anchor pole adapt to the small-scale deformation of confining pressure to a certain extent
And reduce roadway support cost, carry out anchor recovering and allow pressure design that can obtain better economic benefit, meet green and opens
Adopt concept.
Invention content
The utility model is based in real mine roadway support, and anchor recovering rate is low, in supported laneway, not due to anchor pole
The phenomenon that adapting to the deformation of tunnel a small range and often tension damage, therefore propose that anchor pole allows pressure, recycling to act on, and can make anchor
While ensureing supporting effect of roadway, the small-scale deformation of suitable for surrounding rock damages bar without tension, increases anchor recovering rate,
Reduce roadway support cost.
In order to solve the problems, such as the damage of anchor pole and recycling, the utility model the technical scheme adopted is that one kind can return
Receive pressure-relieving achor bar, it is characterised in that：It is machined with internal thread on the inside of casing, is coincide with the mutual Wu of external screw thread of main rod body one end, it is main
The body of rod and casing by screw thread twist-on together with, the exposed junction of main rod body once penetrate flanged plate, allow pressing spring, wedge shape hoop pad,
Endless metal gasket and hex nut, flanged plate are close to lane wall, and wedge shape hoop pad will allow pressing spring to be pressed on flanged plate, and entirely may be used
Recycling pressure-relieving achor bar is pre-tightened by hex nut.
Possessed advantageous effect is the utility model compared with prior art：The utility model is simple in structure, installation side
Just, application is strong, matches with existing roof bolting machine, and main rod body is connected through a screw thread with casing, convenient when anchor recovering,
In the big stress deformation of country rock generation small range, pressing spring is allowed the deformation of suitable for surrounding rock, is unlikely to that anchor pole is made not allow pressure empty
Between and crumble, while can guarantee supporting effect of roadway again, the utility model reduces the spoilage of anchor pole, improves returning for anchor pole
Yield reduces roadway support cost, and techno-economic effect is notable, has higher application and popularization value.
Description of the drawings
Fig. 1 is the principle schematic diagram of the utility model.
Marginal data：1-- main rod body 2-- hex nut 3-- endless metal gasket 4-- wedge shape hoops pad 5--, which allows, presses bullet
Spring 6-- flanged plate 7-- casings.
Specific implementation mode
As shown in figure, main rod body（1）With casing（7）Together by screw thread twist-on, main rod body（1）Exposed junction successively
Penetrate flanged plate（6）, allow pressing spring（5）, wedge shape hoop pad（4）, endless metal gasket（3）And hex nut（2）, flanged plate（6）
It is close to lane wall, wedge shape hoop pad（4）It will allow pressing spring（5）It is pressed on flanged plate（6）On, entire recyclable pressure-relieving achor bar passes through hexagonal
Nut（2）It is pre-tightened, by allowing pressing spring（5）That realizes recyclable pressure-relieving achor bar allows pressure to act on, by main rod body when recycling（1）
With casing（7）It unscrews.
Claims (1)
1. a kind of recyclable pressure-relieving achor bar, this anchor pole include main rod body（1）, hex nut（2）, endless metal gasket（3）, wedge shape
Hoop pad（4）, allow pressing spring（5）, flanged plate（6）, casing（7）, it is characterised in that：Main rod body（1）And casing（7）Connected by screw thread
It connects, flanged plate（6）It is sleeved on main rod body（1）Lane wall is gone up and be close to, allows pressing spring（5）With wedge shape hoop pad（4）Closely, wedge shape hoop pad
（4）With hex nut（2）Between place endless metal gasket（3）, pass through hex nut（2）Recyclable pressure-relieving achor bar is carried out pre-
Tightly, by allowing pressing spring（5）That realizes recyclable pressure-relieving achor bar allows pressure to act on, by main rod body when recycling（1）With casing（7）It twists
It opens.
