Abstract
The utility model discloses a tube seam type anchor rod tension gauge connector, which is characterized in that two wedge-shaped clamping sheets are arranged on the exposed end of the tube seam type anchor rod; an inner sleeve is sheathed outside the two wedge-shaped clamping sheets; and the inner sleeve is provided with an inner thread. The tube seam type anchor rod tension gauge connector also comprises a connecting rod which penetrates through an anchor rod tension gauge, wherein the connecting rod is provided with a connecting cover; the connecting cover is provided with an outer thread matched with the inner thread of the inner sleeve; the connecting cover is connected to the inner sleeve by the outer thread; an exposed end of the connecting rod, which penetrates through the anchor rod tension gauge, is provided with a thread used for a locking nut; an outer sleeve is sheathed on the inner sleeve; one end of the outer sleeve is contacted with an anchored rock surface; and the other end of the outer sleeve is supported on the bottom of the anchor rod tension gauge and is fastened by the locking nut. The tube seam type anchor rod tension gauge connector disclosed by the utility model has the advantages of simple structure and convenience in operation, and the problem of connection of the tube seam type anchor rod and the anchor rod tension gauge is solved.
Description
Technical field
The utility model relates to connector, relates in particular to the connector of pipe-seam type anchor rod and tensiometer.
Background technology
Since last century, the U.S. was applied to mine timbering with anchor pole, go through the development in a century, bolt support technology is widely used.In the bolt support engineering, need the bearing capacity of the anchor-holding force of anchor bolt and the body of rod be detected, generally use the axis force of anchor meter during detection.Existing axis force of anchor meter designs to general anchor pole, and anchor pole can directly pass axis force of anchor meter centre bore.China recent years has been widely applied pipe-seam type anchor rod in the supporting of mine working fragmented rock body.Because the diameter and the structure of pipe-seam type anchor rod are limit, and can not directly pass axis force of anchor meter centre bore, the connectivity problem with the axis force of anchor meter has just appearred when detecting.Therefore need a kind of suitable tensiometer connector.
Summary of the invention
The purpose of the utility model is to solve in the fragmented rock body mine timbering, and the connectivity problem of pipe-seam type anchor rod and axis force of anchor meter provides a kind of simple, reasonable, effective axis force of anchor meter connector.
To achieve these goals, the structure of the utility model connector is: it is to place two wedge shape intermediate plates at the pipe-seam type anchor rod exposed junction, and two wedge shape intermediate plate outsides are with inner sleeve, and inner sleeve is provided with internal thread; It also comprises a connecting rod that passes the axis force of anchor meter; Connecting rod is provided with adapter sleeve; Adapter sleeve is provided with the external screw thread that is complementary with the inner sleeve internal thread; Through external screw thread adapter sleeve is connected on the inner sleeve, the outer drain terminal that connecting rod passes behind the axis force of anchor meter is processed with the screw thread that is used for locking nut; Overlap an outer sleeve on the inner sleeve again, outer sleeve one end with contacted by the scar of anchoring, the other end withstands on axis force of anchor meter bottom, tightens up with locking nut then.
During detection, two wedge shape intermediate plates are clamped anchor pole, and operation axis force of anchor meter pulls out inner sleeve, utilizes the occlusal principle of key to draw tighter and tighter, thereby bites anchor pole; Pulling force passes on the anchor pole, thereby reaches the purpose of axis force of anchor test.
The utility model is simple in structure, connectivity problem easy and simple to handle, as to have solved pipe-seam type anchor rod and axis force of anchor meter.
Description of drawings
Fig. 1 is the unitary construction figure of the utility model embodiment;
Among the figure: the 1-outer sleeve; The 2-inner sleeve; 3-wedge shape intermediate plate; The 4-adapter sleeve; 5-axis force of anchor meter; The 6-connecting rod; The 7-locking nut; The 8-rock; The 9-pipe-seam type anchor rod.
The specific embodiment
As shown in Figure 1, the structure of the utility model connector is: it is to place 3, two wedge shape intermediate plate 3 outsides of two wedge shape intermediate plates at pipe-seam type anchor rod 9 exposed junctions to be with inner sleeve 2, and inner sleeve 2 is provided with internal thread; It also comprises a connecting rod 6 that passes axis force of anchor meter 5; Connecting rod 6 is provided with adapter sleeve 4; Adapter sleeve 4 is provided with the external screw thread that is complementary with inner sleeve 2 internal threads; Through external screw thread adapter sleeve is connected on the inner sleeve 2, the outer drain terminal that connecting rod 6 passes behind the axis force of anchor meter 5 is processed with the screw thread that is used for locking nut 7; Overlap an outer sleeve 1 on the inner sleeve 2 again, outer sleeve 1 one ends with contacted by the scar of anchoring rock 8, the other end withstands on axis force of anchor meter 5 bottoms, tightens up with locking nut 7 then.
