The present invention provides the following embodiments.

[0026] Depend on Figure 1 As shown, it is a structural diagram of the bridge and tunnel engineering slope protection anchor rod in this embodiment, including a limiter 1, a middle-end connecting rod 2 and a cone head 3. The side of the limiter 1 is equipped with a middle-end connecting rod 2 that extends the overall length of the anchor rod, and the end of the middle-end connecting rod 2 is equipped with a cone head 3 for assisting the anchor rod to be inserted. The two sides of the middle-end connecting rod 2 are equipped with docking mechanisms 4 for assisting the middle-end connecting rod 2 to dock, and the inside of the cone head 3 is equipped with a limiter 5 for positioning the auxiliary equipment.

[0027] During use, the middle connecting rod 2 of corresponding length is selected according to the depth of the plug-in groove opened on the inner wall of the bridge or tunnel, and then the middle connecting rod 2 is installed between the limiter 1 and the cone head 3 through the use of the docking mechanism 4. Thereafter, the anchor rod is inserted into the plug-in groove as a whole through the cooperation of the cone head 3, and the position of the anchor rod is preliminarily locked through the operation of the limiting mechanism 5. Finally, through the cooperation of the limiter 1, the middle connecting rod 2 and the cone head 3 itself, concrete is input into the plug-in groove to further lock the position of the anchor rod, and the position of the anchor rod itself is fixed by using the external thread of the limiter 1 and the matching limiting plate to ensure the stability of the equipment during use.

[0028] By the attached Figure 2 As shown, it is a structural diagram of the docking mechanism 4 in this embodiment. The docking mechanism 4 includes a plug-in hole 41, a docking seat 42 and a clamping assembly 43. The plug-in holes 41 are symmetrically opened on both sides of the middle-end connecting rod 2, and docking seats 42 are provided at both ends of the middle-end connecting rod 2. The clamping assembly 43 is installed inside the docking seat 42, and the end of the clamping assembly 43 is engaged with the plug-in hole 41.

[0029] During use, the middle connecting rod 2 is inserted into the docking seat 42 to ensure that the plug-in hole 41 is aligned with the clamping assembly 43 and other components on both sides of the docking seat 42. Then, through the operation of the clamping assembly 43 itself, the internal components of the clamping assembly 43 are inserted into the plug-in hole 41, thereby reinforcing and fixing the position of the middle connecting rod 2 itself, making it easy to quickly adjust the length of the middle connecting rod 2 itself according to the depth of the plug-in slot.

[0030] By the attached Figure 3As shown, it is a structural schematic diagram of the clamping assembly 43 in this embodiment, and the clamping assembly 43 includes a clamping block 431, an extrusion screw 432 and a rotating block 433.

The extrusion screw 432 is threadedly connected to the limiting mechanism 5, and the rotating block 433 is fixedly installed at the end of the extrusion screw 432. The clamping block 431 is engaged with the plug hole 41.

[0031] During use, by rotating the rotating block 433, the extrusion screw 432 is engaged with the inner wall thread of the docking seat 42. With the cooperation of the external thread of the extrusion screw 432, the end of the extrusion screw 432 continuously pushes the position of the clamping block 431, pushing the clamping block 431 into the inside of the plug-in hole 41, completing the clamping connection between the components and realizing the locking of the position of the middle-end connecting rod 2.

[0032] By the attached Figure 2 As shown, it is a structural diagram of the docking mechanism 4 in this embodiment. There are two groups of docking seats 42, which are respectively arranged at the two ends of the middle-end connecting rod 2, and a conveying trough for conveying materials is opened inside the docking seat 42. During use, through the installation and use of the docking seat 42, one group of docking seats 42 is installed at the end of the limit member 1, and the other group is arranged on the side of the cone head 3, which is convenient for installing the middle-end connecting rod 2 between the limit member 1 and the cone head 3.

[0033] By the attached Figure 4 As shown, it is a structural schematic diagram of the limiting mechanism 5 in this embodiment, and the limiting mechanism 5 includes a threaded barrel 51, a threaded rod 52, an extrusion cone 53 and a locking assembly 54. The threaded barrel 51 is fixedly installed inside the cone head 3, the threaded rod 52 is threadedly installed inside the threaded barrel 51, the extrusion cone 53 is installed outside the threaded rod 52, and the locking assembly 54 is symmetrically arranged on both sides of the inner wall of the cone head 3, and the extrusion cone 53 is in extrusion contact with the locking assembly 54.

[0034] During use, the end of the threaded rod 52 is fixedly connected to the side of one group of docking seats 42. By rotating the angle of the limiter 1 itself, the threaded rod 52 itself rotates inside the threaded barrel 51 through the conduction of the docking mechanism 4 and the middle-end connecting rod 2. By utilizing the cooperation between the external thread of the threaded rod 52 and the threaded barrel 51, the threaded rod 52 drives the position of the extrusion cone 53 to move, and squeezes the position of the positioning component 54, so that the positioning component 54 as a whole protrudes from the surface of the cone head 3, and the overall position of the anchor rod is locked, and a limiting ring for limiting the movement distance of the extrusion cone 53 is installed at the side opening of the cone head 3.

[0035] By the attached Figure 5As shown in the figure, it is a structural schematic view of the clamping component 54 in the embodiment, which comprises a rotating seat 541, a rotating rod 542 and a pressing plate 543. The rotating seat 541 is fixedly installed on the inner wall of the taper head 3, the rotating rod 542 is rotatably installed in the rotating seat 541, and the pressing plate 543 is fixedly installed on the outer portion of the rotating rod 542. In use, the movement of the pressing taper 53 position is combined with the bottom surface of the pressing plate 543, the angle of the pressing plate 543 is changed under the cooperation of the rotating rod 542 and the rotating seat 541, the whole pressing plate 543 rotates to the outer side of the taper head 3, and the position of the taper head 3 is locked.

[0036] As shown in the figure, Figure 5 As shown in the figure, it is a structural schematic view of the clamping component 54 in the embodiment, which further comprises a clamping plate 544. The clamping plate 544 is fixedly installed on the upper surface of the pressing plate 543, and the inner wall of the taper head 3 is provided with a matching groove above the clamping plate 544. In use, the installation of the clamping plate 544 enhances the stability of the upper surface of the pressing plate 543 when it is in contact with the rock stratum and stone outside the taper head 3, and the trapezoidal structure of the clamping plate 544 allows the clamping plate 544 to enter the rock stratum, so as to lock the position of the whole taper head 3.

[0037] As shown in the figure, Figure 4 As shown in the figure, the whole pressing taper 53 is conical, and the hollow groove for conveying materials is arranged in the interior of the threaded cylinder 51, the threaded rod 52 and the pressing taper 53. In use, the design of the shape of the pressing taper 53 allows the pressing taper 53 to stably press and push the position of the pressing plate 543, and the hollow groove facilitates the materials to pass through the limiting piece 1, the middle connecting rod 2 and the taper head 3 and enter the rock stratum, so as to lock the position of the whole anchor rod.
