Abstract
The utility model provides an ultralong anchor rod comprising a rod body (2), an anchor head (5) and an anchor tail (1), wherein at least one connecting part(3) is arranged between the anchor head (5) and the anchor tail (1); the anchor head (5) and the anchor tail (1) are fixedly connected or separated by the connecting part (3). With the ultralong anchor rod, the problem that long anchor rod can not be used due to insufficient space of roadways and the like can be solved.
Description
Technical field
The utility model relates to the support engineering technical field, the extra long anchor bar that particularly a kind ofly be used in all kinds of mines, anchoring engineering such as traffic and water conservancy tunnel, military project, civil engineering uses.
Background technology
Along with the development of mine anchor pole, cable bolting technology, anchor pole, anchor cable increase gradually at the consumption of down-hole.In some cases, long anchor pole can be subjected to the restriction in space, down-hole, and for example, when the broken thickness of roof was big, when perhaps the coal seam was thin, owing to be subjected to the restriction of lane space, normal anchor pole can not be installed, and can only use anchor cable that top board is controlled.But,, adopt the cable bolting top board can influence supporting effect because the elongation per unit length of anchor cable is very low.
Summary of the invention
The purpose of this utility model is, a kind of extra long anchor bar is provided, and can solve at present because insufficient space such as tunnel and can not use the problem of long anchor pole.
Extra long anchor bar of the present utility model is made up of the body of rod, anchor head and anchor tail, wherein, is provided with at least one connecting portion between anchor head and anchor tail, by described connecting portion, described anchor head is fixedlyed connected with the anchor tail or separately.
Wherein, described connecting portion comprises first connector and second connector, and described first connector and second connector are built-in with internal thread, has externally threaded connecting bolt by one and carries out fixedly connected.
Wherein, the diameter of described first connector and second connector is bigger than the body of rod.
Wherein, described connecting portion comprises first connector and second connector, and described first connector and second connector are equipped with external screw thread outward, is undertaken fixedly connected by an adapter sleeve with internal thread.
Wherein, the described body of rod is a metallic rod body.
The beneficial effects of the utility model are: according to extra long anchor bar of the present utility model, utilize extra long anchor bar to go for any space environment in down-hole, rock-bolt length designs according to actual needs, design length is 2m～10m, connecting portion can be 1,2 or more, and has the elongation per unit length of general anchor pole, has further improved the supporting quality of anchor pole, compared with prior art, it is safe and reliable, tensile strength is high, elongation per unit length is big, supporting effect is better.

The specific embodiment
Below, 1～2 describe extra long anchor bar of the present utility model in detail with reference to the accompanying drawings.
Extra long anchor bar of the present utility model is made up of the body of rod, anchor head and anchor tail.Wherein, between anchor head and anchor tail, be provided with at least one connecting portion,, anchor head fixedlyed connected with the anchor tail or separately by connecting portion.
As shown in Figure 1, be the structural representation of the extra long anchor bar of the utility model embodiment 1.In the present embodiment, this extra long anchor bar is made up of the body of rod 2, anchor head 5 and anchor tail 1.Wherein, between anchor head 5 and anchor tail 1, be provided with at least one connecting portion 3.Wherein, connecting portion 3 comprises the first connector 3-1 and the second connector 3-2.Wherein, first connector and second connector are built-in with internal thread, have externally threaded connecting bolt 4 by one and carry out fixedly connected.In addition, the diameter of first connector and second connector is bigger than the body of rod 2.When specific implementation, can pass through mechanical processing technique, first connector and the second connector pier is thick, make the diameter of the win connector and second connector bigger than the body of rod 2.In addition, when specific implementation, can also be that first connector and second connector are equipped with external screw thread outward, undertaken fixedly connected by an adapter sleeve with internal thread then.
Based on noted earlier, directly push up relatively fragmentation and thickness big (for example above 5 meters) in the coal seam and just stable rock stratum can be arranged, if can not play the effect of supporting roof with general anchor pole, can't finish with the scene, mounting process down-hole that 6 meters anchor pole is present, can only use anchor cable in the prior art, but the elongation per unit length of anchor cable is very low, effectively supporting roof.Use extra long anchor bar of the present utility model to design its length according to actual conditions, such as 3 meters long anchor poles being connected for two sections, make its effective length reach 6 meters, utilize on-the-spot instrument to install very easily, overcome the low weakness of anchor cable elongation per unit length, really reached the purpose of stablizing top board.
In addition, the very thin coal seam of exploitation, the ore deposit that has, for example anchor pole below 1 meter can only be used in 1 meter coal seam, can not anchor to stablize the position, rock stratum, also effective supporting roof just.Utilize extra long anchor bar to can be designed as 2 meters or longer, 0.6 meter every section, with 2～4 sections or connect, utilize on-the-spot instrument to install very easily more, overcome the low weakness of anchor cable elongation per unit length, improved the supporting quality of anchor pole.
In sum, according to extra long anchor bar of the present utility model, utilize extra long anchor bar to go for any space environment in down-hole, rock-bolt length designs according to actual needs, and design length is 2m～10m, and connecting portion can be 1,2 or more, and elongation per unit length with general anchor pole, further improved the supporting quality of anchor pole, compared with prior art, it is safe and reliable, tensile strength is high, elongation per unit length is big, supporting effect is better.
More than be in order to make those of ordinary skills understand the utility model; and to detailed description that the utility model carried out; but can expect; in the scope that does not break away from claim of the present utility model and contained, can also make other variation and modification, these variations and revising all in protection domain of the present utility model.
