Abstract
The utility model relates to a waney metal rod body for anchoring, belonging to the metal rod body for the anchoring of mine tunnels. The utility model is characterized in that the anchor-in segment of the rod body is waney with the top nut segment on the tail of the rod body; the screw thread external diameter of the top nut segment on the tail of the rod body is larger than the diameter of the anchor-in segment of the rod body. The utility model is beneficial to enhancing the intensity of the whole rod body, which can reach the equal strength of the rod body and enhance the safety performance; raw materials are saved consequently; The waney metal rod body for anchoring can be used for the support of the mine tunnels, and can be also used for the engineering support of other industries simultaneously.
Description
(1) technical field: the utility model is the not isometrical metallic rod body of a kind of anchoring, is mainly used in the mine safety anchoring, can be used on the underworkings supporting.It belongs to mine laneway support anchoring metallic rod body.
(2) background technology: the anchor pole that mine is used for anchoring be by metallic rod body, resin anchoring agent or cement anchoring agent, special nut, pallet is supporting forms.Its metallic rod body is by low vertical muscle or not have vertical muscle screw-thread steel be that mother metal is made, and it is made of the thread segment of body of rod section of anchoring into and afterbody top nut, and the external diameter of the thread segment of its afterbody top nut is less than or equal to body of rod diameter.Because the external diameter of afterbody top nut thread segment is less than or equal to the diameter of the body of rod, certainly will cause the metallic rod body bulk strength not wait by force, the intensity of afterbody top nut thread segment can weaken greatly, causes the safety in utilization of anchor pole to have substantial degradation.
(3) summary of the invention: the purpose of this utility model mainly adopts not isometrical metallic rod body design, solves the problem of lever strength inequality, improves the safety in utilization of anchor pole.
Anchoring described in the utility model is used not, and the design scheme of isometrical metallic rod body is: it is made of body of rod section of anchoring into and afterbody top nut section.Be characterized in their not equal diameters, the major diameter of thread of body of rod afterbody top nut section is greater than the diameter of the body of rod section of anchoring into.
Originally make real novel described anchoring compared with prior art with not isometrical metallic rod body, its useful contribution is owing to the major diameter of thread of body of rod afterbody top nut section increases its intensity greater than the diameter of the body of rod section of anchoring into, help improving the intensity of the whole body of rod, the grade that can reach the body of rod is strong, improves safe application performance.Raw material have also correspondingly been saved simultaneously.
(4) description of drawings: Fig. 1 is the utility model schematic diagram.
(5) specific embodiment: 1 pair of anchoring of the present utility model is with being further described as follows with not isometrical metallic rod body in conjunction with the accompanying drawings: anchoring described in the utility model is to be made of body of rod section of anchoring into 1 and body of rod afterbody top nut section 2 with not isometrical metallic rod body, is characterized in their not equal diameters.The major diameter of thread d of its afterbody top nut section 2 is greater than the diameter D of the body of rod section of anchoring into 1.The utility model is mother metal with the screw-thread steel.
Claims (2)
1, a kind of anchoring is to be made of body of rod section of anchoring into (1) and body of rod afterbody top nut section (2) with not isometrical metallic rod body, and it is characterized in that: the body of rod section of anchoring into (1) is not isometrical with body of rod afterbody top nut section (2).
2, anchoring according to claim 1 is characterized in that: the described not isometrical diameter D that is the major diameter of thread d of body of rod afterbody top nut section (2) greater than the body of rod section of anchoring into (1) with not isometrical metallic rod body.
