Technical field
The utility model relates to a kind of mining supports device, is exactly a kind of expansion recovering stock.
Background technology
The existing anchor pole that mining industry is used exists and only can disposablely use, the problem that is difficult to recycle and reuse.It causes the wasting of resources of a large amount of material material, and meanwhile, the anchor pole being retained in rock mass also can form potential threat to mining machinery.
Utility model content
The purpose of this utility model, has been to provide a kind of expansion recovering stock, and it can overcome existing anchor pole and is difficult to recycle, and causes the wasting of resources and has the problem of potential safety hazard.
The purpose of this utility model is achieved through the following technical solutions: expansion recovering stock, comprise anchor bar body, and the periphery of anchor bar body is installed expansion sleeve, evenly offers at least two saturating grooves on the anterior sidewall of expansion sleeve; The front end of anchor bar body is provided with frustum, and the taper end of frustum is connected with anchor bar body; The rear end of anchor bar body passes outside expansion sleeve and is provided with screw thread, and supporting plate and nut are installed on the rear end of anchor bar body, and the through hole of supporting plate coordinates with anchor bar body, and supporting plate is between expansion sleeve and nut.
For further realizing the purpose of this utility model, can also realize by the following technical solutions: described supporting plate is square.Described supporting plate is provided with hemispherical bumps, is provided with arc groove in hemispherical bumps, and arc groove communicates with through hole.Junction plate is established in the rear end of described expansion sleeve, and junction plate is provided with connecting hole; Supporting plate is provided with stopper slot, and stopper slot coordinates with junction plate.The anterior periphery of described expansion sleeve is provided with several bar shaped convex edges.The inwall of described expansion sleeve front portion is provided with cone tank, and cone tank communicates with saturating groove; Cone tank coordinates with frustum.
Good effect of the present utility model is: it both can utilize expansion sleeve and anchor bar body cooperation that anchor pole and rock mass are fixedly secured, can conveniently anchor bar body and expansion sleeve be removed respectively to recovery again, whole installation and removal process simple and efficient to handle, can realize the recycling of real meaning, and eliminate the threat of anchor pole to gas production machinery.Its supporting plate is provided with hemispherical bumps, is provided with arc groove in hemispherical bumps, can, increasing hardly under the prerequisite of supporting plate overall weight, significantly increase the intensity of supporting plate.The rear portion of expansion sleeve is provided with junction plate, can further facilitate the integral demounting of construction party to anchor pole.
Accompanying drawing explanation
Fig. 1 is the structural representation of expansion recovering stock described in the utility model; Fig. 2 is the profile along A-A line in Fig. 1, and Fig. 3 is the sectional view along B-B line in Fig. 1.
Reference numeral: saturating groove 8 hemispherical bumps 9 arc groove 10 connecting hole 11 bar shaped convex edge 12 frustum 13 screw thread 14 through hole 15 cone tanks of 1 expansion sleeve 2 anchor bar body 3 supporting plate 4 nut 5 stopper slot 6 junction plate 7.
The specific embodiment
As shown in Figure 1, expansion recovering stock described in the utility model, comprises anchor bar body 2.The periphery of anchor bar body 2 is installed expansion sleeve 1.Anchor bar body 2 can move by relative expansion cover 1.As shown in Figure 1, on the anterior sidewall of expansion sleeve 1, evenly offer at least two saturating grooves 7, so that anchor bar body 2 can be by the anterior distending of expansion sleeve 1, thereby make anchor pole and rock fixation.Preferred version is four saturating grooves 7.For ease of anchor bar body 2, by expansion sleeve 1 distending, the front end of anchor bar body 2 is provided with frustum 12, and the taper end of frustum 12 is connected with anchor bar body 2.The rear end of anchor bar body 2 passes outside expansion sleeve 1 and is provided with screw thread 13.Supporting plate 3 and nut 4 are installed on the rear end of anchor bar body 2.The through hole 14 of supporting plate 3 coordinates with anchor bar body 2.Supporting plate 3 is between expansion sleeve 1 and nut 4.During use, first by the rear end of anchor bar body 2, the front end by expansion sleeve 1 penetrates in expansion sleeve 1; Again supporting plate 3 is connected with anchor bar body 2 respectively with nut 4; Finally, the front end of expansion sleeve 1 and anchor bar body 2 is inserted in the hole of holding successfully in advance on crag, and rotating nut 4, anchor bar body 2 relative expansion covers 1 are pulled back, so that frustum 12 is by the front end distending of expansion sleeve 1, anchor pole is embedded in rock securely.While removing anchor pole, the nut 4 of first outwarding winding, makes anchor bar body 2 cease to binds; With pneumatic hammer, impact anchor bar body 2 again, anchor bar body 2 and expansion sleeve 1 are unclamped, the front end retracted for clearance of expansion sleeve 1; Finally, whole anchor pole is taken out in the hole by crag.
For convenience of processing and manufacturing, as shown in Figure 3, described supporting plate 3 can be square.
In order to increase the intensity of supporting plate 3, as shown in Figure 1, described supporting plate 3 is provided with hemispherical bumps 8, is provided with arc groove 9 in hemispherical bumps 8, and arc groove 9 communicates with through hole 14.
More convenient for making to remove anchor pole, as shown in Figure 1, junction plate 6 is established in the rear end of described expansion sleeve 1.Junction plate 6 is provided with connecting hole 10.Supporting plate 3 is provided with stopper slot 5, and stopper slot 5 coordinates with junction plate 6.By pulling the junction plate 6 just can be by anchor bar body 2 by taking out in hole.Conventionally in order to make expansion sleeve 1 stressed evenly, as shown in Figure 1, on expansion sleeve 1, can be provided with two junction plates 6.
More firm for anchor pole is connected with crag, as depicted in figs. 1 and 2, the anterior periphery of described expansion sleeve 1 is provided with several bar shaped convex edges 11.For convenience of processing, can process in the periphery of expansion sleeve 1 screw-shaped bar shaped convex edge 11.
As shown in Figure 1, the inwall of described expansion sleeve 1 front portion is provided with cone tank 15.Cone tank 15 communicates with saturating groove 7; Cone tank 15 coordinates with frustum 12, and in the time of can effectively reducing swelling, the local pressure that 12 pairs of expansion sleeves 1 of frustum cause, prevents that expansion sleeve 1 local pressure is excessive and damage.
The utility model not technology contents of detailed description is known technology.
