Abstract
The utility model disclosing whole recovery type anchor rod pertains to anchor technology field in mine. The model has technical features that consisting of expanded tubes with a certain taper, anchorage bodies comprising of expansion bushing with dilatation joints as well as rod body, at least two anchorage bodies are provided and connected with the rod body in series successively. The problems of material wasting and poor anchorage strength of present whole recovery type anchor rod are solved. The model can be extensively used for anchorages in all kinds of roadway.
Description
Technical field
The utility model belongs to mine anchor pole technical field, relates in particular to full reclaiming type anchor pole.
Background technology
The anchor pole that uses anchoring to use in the present mine, the anchoring body that adopts expand tube that has certain taper on body of rod top and the expansion set that has dilatation joint to form mostly, the depth according to required anchor hole, select the body of rod of different length, when the body of rod is longer, it is anchor rod anchored not firm to cause, accident such as cause that the tunnel caves in easily.In order to increase anchoring strength, people's take to extend length of expand tube and expansion set like this, not only cause the waste of material, and effective active area is limited between expansion set and the anchor hole, increases the DeGrain of anchoring strength.
The utility model content
Technical problem to be solved in the utility model just provides a kind of material, easy for installation, full reclaiming type anchor pole that anchoring strength is big saved.
For solving the problems of the technologies described above, technical scheme provided by the utility model is: full reclaiming type anchor pole, comprise the anchoring body and the body of rod be made up of expand tube that has certain taper and the expansion set that has dilatation joint, described anchoring body is at least two, and is serially connected in successively on the described body of rod.
Its additional technical feature is: described anchoring body is three; Described dilatation joint is positioned at the expansion set front end, be provided with the nut that is connected as a single entity with expansion set in the rear end of expansion set, be provided with the first opposite screw thread of hand of spiral that is positioned at expand tube with the body of rod at the described body of rod and nut correspondence position, the internal thread of described nut and first screw thread are complementary; Outside wall surface at the first half of described expansion set is provided with anti-slide mark or non-slip process.
Full reclaiming type anchor pole provided by the utility model compared with prior art, have the following advantages: one, because anchoring body is at least two, and be serially connected in successively on the described body of rod, not only increase effective active area between expansion set and the anchor hole, increased anchoring strength, and, also save material, reduced its manufacturing cost; Its two owing to be provided with the nut that is connected as a single entity with expansion set, be provided with the first opposite screw thread of hand of spiral that is positioned at expand tube with the body of rod at the body of rod and the first nut correspondence position in the rear end of expansion set; When installing, rotate the body of rod, in the time of the expand tube rollback, the expansion set reach has reduced the displacement of the body of rod, has increased anchoring strength, when taking off anchor pole, the backward rotation body of rod, in the time of the expand tube reach, the expansion set rollback, expansion set front end retraction can take out very smoothly; Its three owing to be provided with anti-slide mark or non-slip process, increased the frictional force between expansion set and the anchor hole in outside wall surface at the first half of described expansion set, prevented relative slip between expansion set and the anchor hole.
Description of drawings
The structural representation of the full reclaiming type anchor pole that accompanying drawing provides for the utility model.
The specific embodiment
Be described in further details below in conjunction with the structure of the drawings and specific embodiments the full reclaiming type anchor pole of the utility model.
As shown in drawings, the partial sectional view of full reclaiming type anchor pole, comprise expand tube 1 and the expansion set 2 made by rubber-plastics material, expand tube 1 has certain taper, on expansion set 2, have dilatation joint 3, expand tube 1 and expansion set 2 are formed anchoring body, and expand tube 1 and expansion set 2 are respectively three, and are serially connected in successively on the body of rod of being made by metal material 4.Certainly, according to the depth of coal seam and anchor hole, expand tube 1 and expansion set 2 respectively can be for more than two or three.Expand tube 1 has internal thread, and the body of rod 4 is provided with second external screw thread 5 with expand tube 1 correspondence position, and the internal thread of expand tube 1 and second external screw thread 5 are complementary.
In order to increase the frictional force between expansion set and the anchor hole, prevented relative slip between expansion set and the anchor hole, be provided with anti-slide mark 8 in the outside wall surface of the first half of expansion set 2.Also can be provided with non-slip process (not drawing among the figure).
During installation, the body of rod 4 that cover is connected is installed in the anchor hole, rotates the body of rod 4, and in the time of expand tube 1 rollback, expansion set 2 reaches have reduced the displacement of the body of rod 4, have increased anchoring strength; When taking off anchor pole, the backward rotation body of rod 4, in the time of expand tube 1 reach, expansion set 2 rollbacks, the expansion set front end bounces back under the effect of anchor hole wall, outwards spurs the body of rod 4, and expand tube 1 and expansion set 2 can take out very smoothly.
Claims (4)
1, full reclaiming type anchor pole comprises the anchoring body and the body of rod be made up of expand tube that has certain taper and the expansion set that has dilatation joint, and it is characterized in that: described anchoring body is at least two, and is serially connected in successively on the described body of rod.
2, full reclaiming type anchor pole according to claim 1, it is characterized in that: described anchoring body is three.
3, full reclaiming type anchor pole according to claim 1 and 2, it is characterized in that: described dilatation joint is positioned at the expansion set front end, be provided with the nut that is connected as a single entity with expansion set in the rear end of expansion set, be provided with the first opposite screw thread of hand of spiral that is positioned at expand tube with the body of rod at the described body of rod and nut correspondence position, the internal thread of described nut and first screw thread are complementary.
4, full reclaiming type anchor pole according to claim 3 is characterized in that: the outside wall surface at the first half of described expansion set is provided with anti-slide mark or non-slip process.
