Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses an anchor rod with adjustable be used for fixed non-excavation rig, including shell 1, shell 1 cavity and one end opening, the one end that the open face was kept away from to shell 1 is equipped with closed angle 11. The driving-in of the anchor rod is convenient.

Four mounting seats 12 are fixed on the top of the housing 1, the four mounting seats 12 are uniformly distributed around the outer peripheral surface of the housing 1, the mounting seats 12 are provided with positioning holes 13 which vertically penetrate through, and reinforcing bolts (not shown in the figure) are slidably connected in the positioning holes 13.

Referring to fig. 4 and 5, the inner rod 2 is slidably connected inside the outer shell 1, and the inner rod 2 is matched with the inner size of the outer shell 1. A plurality of mounting grooves 21 are opened to the circumference lateral wall of interior pole 2, and a plurality of mounting grooves 21 are around the axis evenly distributed of interior pole 2. A shaft rod 22 is fixed in the mounting groove 21, and the length direction of the shaft rod 22 is perpendicular to the length direction of the inner rod 2. The inner rod 2 is rotatably connected with a reinforcing rod 23 through each shaft rod 22. The anchor strut 23 is equipped with connecting plate 231, and the shaft hole has been seted up to connecting plate 231, and every connecting plate 231 all carries out the rotation through shaft hole and the axostylus axostyle 22 that corresponds and is connected. In addition, one end of the connection plate 231 located in the installation groove 21 is provided with a segment of arc surface so that the reinforcing bar 23 can rotate in the installation groove 21.

Correspondingly, a plurality of avoiding grooves 3 are formed in the shell 1, and each reinforcing rod 23 is arranged in the corresponding avoiding groove 3. The avoiding groove 3 comprises a bottom groove wall 31 and a top groove wall 32 which are opposite, the plane where the bottom groove wall 31 is located is perpendicular to the axis of the shell 1, the top groove wall 32 is an arc surface, the distance between the top groove wall 32 and the bottom groove wall 31 is gradually reduced along the direction close to the outer peripheral surface of the shell 1, one end, abutted against the bottom groove wall 31, of the reinforcing rod 23 is an abutting surface 232, and the abutting surface 232 is an arc surface, so that the reinforcing rod 23 can penetrate out of or retract into the storage groove conveniently.

In order to limit the movement of the inner rod 2 relative to the shell 1, four limiting grooves 14 are formed in one end, close to the opening surface, of the interior of the shell 1, and the four limiting grooves 14 are uniformly distributed around the axis of the shell 1. The length direction of the limiting groove 14 is parallel to the axial direction of the inner rod 2 and the shell 1, and the limiting groove 14 is not communicated with the outside of the shell 1.

Correspondingly, when interior pole 2 is kept away from the fixed stopper 24 that is provided with the adaptation with spacing groove 14 of shell 1's one end, when stopper 24 is located the bottom of spacing groove 14, interior pole 2 is located shell 1 inside completely and every stiffener 23 and wears out in shell 1 outside by dodging groove 3, and when stopper 24 was located the top of spacing groove 14, every stiffener 23 all was located and dodges inside groove 3, and interior pole 2 top is equipped with control unit.

The top of the inner rod 2 is provided with a screw hole, the control part comprises an operating rod 4, one end of the operating rod 4 is provided with a thread section 42 matched with the screw hole, and the other end of the operating rod 4 is fixed with a push plate 41 vertical to the operating rod 4.

The implementation principle and the beneficial effects of the embodiment are as follows:

by applying pressure to the mounting bracket, the anchor is driven into the ground and depending on the circumstances it is chosen whether to add a reinforcing anchor in the mounting 12. Confirm that shell 1 is firm after, pass through threaded connection installation action bars 4 at the top of interior pole 2, through exerting pressure to the clamp plate, with interior pole 2 impress inside shell 1 completely, under the drive of interior pole 2, reinforcement bar 23 all wears out the shell 1 outside from respective groove 3 of dodging, further promotes its stability after squeezing into underground. In addition, if the anchor rod needs to be taken out, an upward pulling force is applied to the pushing plate 41, so that the reinforcing rod 23 is retracted into the avoiding groove 3, the outer surface of the anchor rod is relatively smooth, and the anchor rod is convenient to take out. The reinforcing rods 23 which penetrate out transversely increase the friction force, the pressure and the like between the outer surface of the anchor rod and the soil layer, so that the anchor rod has a better reinforcing effect, and when the anchor rod is driven into or pulled out, the reinforcing rods 23 are folded, and the anchor rod can be pulled out easily.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
