The invention is further described below with reference to the accompanying drawings:
example 1
As shown in fig. 1-9, a self-locking type anti-pulling anchor rod comprises an anchor rod 1 used for drilling and a plugboard 5 used for locking the bottom, wherein a tip 3 is fixedly arranged at the bottom of the anchor rod 1 and provided with a feed thread 2 uniformly formed on the outer circular surface of the anchor rod 1, a locking screw rod 6 is axially arranged inside the anchor rod 1, an adjusting block 7 is connected to the locking screw rod 6 through threads, the adjusting block 7 is positioned at the bottom side inside the anchor rod 1, three connecting rods 8 are uniformly arranged on the outer circular surface of the adjusting block 7, the outer side of the connecting rods 8 is connected with the plugboard 5 through a pin shaft, a guide opening 4 is formed between the plugboard 5 and the anchor rod 1, a guide block 41 is arranged at the opening position of the bottom of the guide opening 4, and an extrusion groove 9 opposite to the feed thread 2 is formed on one side of the guide opening 4.
Preferably: the locking screw rod 6 is rotationally connected with the anchor rod 1 through a limiting ring.
So set up, locking screw 6 rotates and connects stock 1, and when joining in marriage with stock 1 through the spacing ring, avoid locking screw 6 to break away from stock 1 inside.
Preferably: the extrusion groove 9 is integrally formed with the anchor rod 1.
So set up, extrusion groove 9 be with feed screw thread 2 revolve the opposite groove, so when extrusion groove 9 extrudeed picture peg 5, picture peg 5 can form with feed screw thread 2 opposite to the structure of revolveing, impels picture peg 5 to cooperate stock 1 to form reverse spiral structure, cooperates simultaneously and feeds screw thread 2, two sets of opposite structures of revolve to, guarantees stock 1's stability.
Preferably: the guide opening 4 and the guide block 41 are integrally formed with the anchor rod 1.
Preferably: the adjusting block 7 and the connecting rod 8 are integrally formed, and the connecting rod 8 is made of 65Mn spring steel.
So set up, picture peg 5 receives extrusion back in extrusion groove 9, and picture peg 5 takes place the dislocation, and on the torsion transmission was to connecting rod 8 simultaneously, makes connecting rod 8 form the torsion to impel picture peg 5 to take place the upset card and advance extrusion groove 9, thereby guarantee the locking of picture peg 5 in extrusion groove 9.
Preferably: the plugboard 5 is divided into an extending section and a reserved section, and the reserved section corresponds to the extrusion groove 9 when the plugboard 5 is in an unfolded state.
Working principle: the initial state is as follows: after the anchor rod 1 is inserted into the borehole, the anchor rod 1 is rotated by a tool, and the anchor rod 1 is fed into the borehole through the feed screw thread 2;
when the feeding screw thread 2 is propped in the hole, the locking screw rod 6 is primarily screwed by a spanner, the locking screw rod 6 is matched with the adjusting block 7 by the screw thread, the adjusting block 7 drives the connecting rod 8 and the inserting plate 5 to move downwards, the inserting plate 5 slides in the anchor rod 1, the bottom surface of the inserting plate 5 is propped against the guiding block 41 and starts to turn outwards (change from fig. 1 to fig. 2), and when the three inserting plates 5 are outwards extended, the action of shoveling up soil and inserting is designed, so that surrounding soil is prevented from being outwards pushed, and a cavity is prevented from being formed;
when the state change is reversed: after the adjusting block 7 is driven by the locking screw 6 to move down to the bottom, the three plugboards 5 are shaped as shown in the state of fig. 2, at this time, the feeding screw thread 2 is continuously screwed by using a tool, the three plugboards 5 inserted in the figure are subjected to forward torque, and because the extrusion groove 9 is a forward and reverse groove, the rotation direction of the extrusion groove 9 is just opposite to that of the feeding screw thread 2, the plugboards 5 are clamped inside the extrusion groove 9 after being subjected to torque, and continuously subjected to torque and the mortgage force of the extrusion groove 9, so that the plugboards 5 are slidably twisted inside the extrusion groove 9, and are driven to twist when being twisted because the connecting rod 8 is made of spring steel, until the plugboards 5 are completely clamped in the extrusion groove 9, the plugboards 5 form a reverse rotation state, and the reverse rotation state is just opposite to that of the feeding screw thread 2, no matter any direction torque or tension is applied to the outside, the feeding screw thread 2 or the plugboards 5 can be meshed with soil layers, and the detachment of the anchor rod 1 is avoided.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
