Description

Technical Field

[0001] The invention relates to the technical field of anchoring devices, in particular to a rock and soil slope reinforcement device. Background Art

[0002] Landslide, as a common geological disaster, usually refers to the phenomenon of geological structure displacement change in which soil blocks on the slope move downward along the fragile zone of the slope under the action of their own weight due to rainfall erosion, water inundation, ground vibration and human activities.

[0003] Usually, in order to prevent the occurrence of landslides, the areas prone to landslides are covered with protective nets to prevent the movement of soil. The protective nets are fixed with anchoring devices, or the slope surface is directly fixed with anchoring devices.

[0004] The existing anchoring device has a plurality of rod-shaped structures arranged in a main sleeve, which can extend out of the main sleeve and be inserted into the soil. When encountering harder soil, the rod-shaped structures are difficult to extend and insert into the soil, resulting in a decrease in the anchoring effect of the anchoring device. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a rock slope reinforcement device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0007] A rock slope reinforcement device, comprising:

[0008] A main sleeve, wherein the main sleeve is provided with a drill rod through hole;

[0009] an insertion head, the insertion head being fixed to the lower end of the main sleeve;

[0010] An insertion tube, the insertion tube is inserted into the main sleeve;

[0011] A drilling drive rod, the drilling drive rod is arranged in the insertion tube, the drilling drive rod is rotatably connected to the insertion tube; the drilling drive rod is fixed with a plurality of drilling drive worms;

[0012] and a drill rod assembly, the drill rod assembly comprising:

[0013] A rotating sleeve, the rotating sleeve is rotatably connected to the insertion tube, a driving worm gear is fixed to the end of the rotating sleeve, and the driving worm gear is meshed with the driving worm;

[0014] A drill rod, the drill rod perforations are arranged corresponding to the drill rod perforations, a spiral groove is arranged at the front end of the drill rod, the drill rod rotates with the rotating sleeve, and the drill rod is slidably connected to the rotating sleeve;

[0015] A threaded sleeve is fixed to the insertion tube and is threadedly connected to the rear end of the drill rod.

[0016] As a further improvement of the above technical solution, a limit assembly is provided between the main sleeve and the insertion tube, and the limit assembly includes a limit groove and a limit strip, and the limit groove and the limit strip both extend in the up and down directions; the limit groove and the limit strip are respectively arranged on the main sleeve and the insertion tube, and the limit groove and the limit strip are plug-fitted.

[0017] As a further improvement of the above technical solution, a guide assembly is provided between the rotating sleeve and the drill rod, and the guide assembly includes a guide groove and a guide bar, and the guide groove and the guide bar both extend along the length direction of the rotating sleeve; the guide groove and the guide bar are respectively arranged on the rotating sleeve and the drill rod, and the guide bar is slidably connected to the guide groove.

[0018] As a further improvement of the above technical solution, the insertion head is a conical component.

[0019] As a further improvement of the above technical solution, the drill rod is arranged obliquely, and the front end of the drill rod is higher than the rear end of the drill rod.

[0020] As a further improvement of the above technical solution, there are multiple drill rod assemblies, and the multiple drill rod assemblies are arranged in the up and down direction.

[0021] As a further improvement of the above technical solution, there are multiple drill rod assemblies, and the multiple drill rod assemblies are arranged in a circular array around the central axis of the insertion tube.

[0022] As a further improvement of the above technical solution, the main sleeve is installed with a plurality of fixing pins, which are movably connected to the main sleeve and can move radially relative to the main sleeve. When the insertion tube is inserted into the main sleeve, the fixing pins move radially along the main sleeve and extend out of the main sleeve.

[0023] As a further improvement of the above technical solution, a chamfered structure is provided on the lower edge of the insertion tube.

[0024] As a further improvement of the above technical solution, a wrench groove is provided at the upper end of the drilling drive rod.

[0025] The beneficial effect of the present invention is that before inserting the rock and soil slope reinforcement device, a hole for inserting the rock and soil slope reinforcement device is first drilled in the soil using other tools, and then the main sleeve and the insertion head are inserted into the hole. After the main sleeve and the insertion head are placed in place, the staff inserts the insertion tube into the main sleeve, and then the staff uses the tool to drive the drilling drive rod to rotate. Since the drilling drive rod is fixed with a driving worm and the rotating sleeve is fixed with a driving worm gear, the rotating sleeve will rotate around its own axis when the drilling drive rod rotates. Since the drill rod can rotate with the rotating sleeve, and the rear end of the drill rod is threadedly connected to the fixed threaded sleeve, when the rotating sleeve rotates, the drill rod rotates with the rotating sleeve and moves in the direction away from the threaded sleeve, so that the drill rod passes through the drill rod hole, out of the main sleeve and inserted into the soil. Since the movement of the drill rod is to rotate and move forward at the same time, combined with the spiral groove at the front end of the drill rod, the drill rod can cut the soil to a certain extent, so that the drill rod can be more easily inserted into the soil, making the present rock and soil slope reinforcement device more suitable for harder soil, which is beneficial to ensuring the anchoring effect of the present rock and soil slope reinforcement device.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0034] Reference Figures 1 to 4 A rock slope reinforcement device includes: a main sleeve 100, an insertion head 200, an insertion tube 300, a drilling drive rod 400 and a drill rod assembly 500.

[0035] The main sleeve 100 is a cylindrical structure. The main sleeve 100 is provided with a plurality of drill rod through holes 110 . The plurality of drill rod through holes 110 are evenly arranged in the main sleeve 100 .

[0036] Specifically, in this embodiment, the main sleeve 100 is equipped with a plurality of fixing nails 120, which are slidably connected to the main sleeve 100, and the fixing nails 120 can move radially relative to the main sleeve 100, so that the fixing nails 120 extend out of the main sleeve 100 or are retracted into the main sleeve 100. When the fixing nails 120 extend out of the main sleeve 100, the fixing nails 120 contact the soil outside the main sleeve 100, and the main sleeve 100 can be initially fixed.

[0037] The insertion head 200 is disposed at the lower end of the main sleeve 100, and the insertion head 200 is fixedly connected to the lower end of the main sleeve 100. Specifically, the insertion head 200 is a conical structure to guide the insertion of the geotechnical slope reinforcement device, so that the geotechnical slope reinforcement device can be more easily inserted into the soil.

[0038] The insertion tube 300 is a cylindrical structure, and the insertion tube 300 is inserted into the main sleeve 100. Specifically, in the present embodiment, a limiting assembly 600 is provided between the insertion tube 300 and the main sleeve 100, and the limiting assembly 600 includes a limiting strip 610 and a limiting groove 620, and the limiting strip 610 and the limiting groove 620 both extend in the up-down direction. Specifically, in the present embodiment, the limiting groove 620 is provided on the inner side wall of the main sleeve 100, and the limiting strip 610 is fixed to the outer side wall of the insertion tube 300, and the limiting strip 610 is plugged and slidably connected with the limiting groove 620, and by providing the limiting assembly 600, the rotation of the insertion tube 300 relative to the main sleeve 100 can be avoided.

[0039] Specifically, in the present embodiment, a chamfered structure 310 is provided at the lower end edge of the insertion tube 300. By providing the chamfered structure 310 at the lower end edge of the insertion tube 300, during the process of inserting the insertion tube 300 into the main sleeve 100, the chamfered structure 310 will push the fixing nail 120 to move in a direction away from the central axis of the main sleeve 100, thereby preventing the fixing nail 120 from getting stuck in the insertion tube 300 and causing the insertion tube 300 to be unable to continue to be inserted. At the same time, the step of moving the fixing nail 120 to one side can also be reduced, and the fixing nail 120 can be automatically pushed out during the insertion process of the insertion tube 300, thereby improving the installation efficiency of the present rock and soil slope reinforcement device.

[0040] The drilling drive rod 400 is disposed in the insertion tube 300, and the drilling drive rod 400 is rotatably connected to the insertion tube 300. A wrench groove 410 is provided at the upper end of the drilling drive rod 400, and the wrench groove 410 is used to connect with a tool, and the tool drives the drilling drive rod 400 to rotate relative to the insertion tube 300 through the wrench groove 410.

[0041] A driving worm 420 is fixed to the drilling driving rod 400 (in the accompanying drawings, the driving worm 420 is shown in a simplified manner). Specifically, in this embodiment, the number of the driving worms 420 is set to four, and the four driving worms 420 are arranged equidistantly in the vertical direction. In other embodiments, the number of the driving worms 420 can also be set to five, six, etc., and those skilled in the art can select the number of the driving worms 420 according to actual needs.

[0042] In the present embodiment, the number of drill rod assemblies 500 is set to be multiple, and the multiple drill rod assemblies 500 are arranged at equal intervals in the up and down directions, and are arranged at equal intervals around the axis of the main sleeve 100. More specifically, the number of drill rod assemblies 500 in the present embodiment is set to eight, and the eight drill rod assemblies 500 are divided into four layers. The two drill rod assemblies 500 in each layer are centrally symmetrical about the central axis of the main sleeve 100, and the four layers of drill rod assemblies 500 are arranged at equal intervals in the up and down directions.

[0043] Specifically, the drill rod assembly 500 includes a rotating sleeve 510 , a drill rod 520 and a threaded sleeve 530 .

[0044] The rotating sleeve 510 is arranged corresponding to the drill rod through hole 110, and the rotating sleeve 510 is rotatably mounted on the insertion tube 300. A driving worm gear 511 is fixedly arranged at one end of the rotating sleeve 510 close to the central axis of the main sleeve 100 (in the drawings, the driving worm gear 511 is shown in a simplified manner), and the driving worm gear 511 is meshed with the driving worm 420. Specifically, in this embodiment, the central axis of the rotating sleeve 510 is arranged at an angle to the central axis of the main sleeve 100, and the height of the rotating sleeve 510 gradually increases away from the central axis of the main sleeve 100.

[0045] When the drilling drive rod 400 rotates, the driving worm 420 will rotate. Since the driving worm wheel 511 is engaged with the driving worm 420, the driving worm 420 will drive the driving worm 420 to rotate, thereby driving the rotating sleeve 510 to rotate around its own axis, thereby realizing staggered axis transmission.

[0046] The drilling rod 520 is installed in the rotating sleeve 510. The drilling rod 520 can move relative to the rotating sleeve 510 along the axial direction of the rotating sleeve 510.

[0047] See also Figure 2 and Figure 3 Specifically, in this embodiment, the drill rod 520 is arranged horizontally. In other embodiments, the rotating sleeve 510 and the drill rod 520 are arranged obliquely relative to the main sleeve 100. Since the rotating sleeve 510 and the drill rod 520 are arranged obliquely relative to the main sleeve 100, the front end of the drill rod 520 is higher than the rear end of the drill rod 520. As a result, the drill rod 520 is inserted into the soil body obliquely upward, thereby improving the pull-out resistance of the rock and soil slope reinforcement device and effectively improving the anchoring performance of the rock and soil slope reinforcement device. The solution of the rotating sleeve 510 and the drill rod 520 being arranged obliquely relative to the main sleeve 100 is not shown in the figure.

[0048] The drill rod 520 can rotate with the rotating sleeve 510. Specifically, in this embodiment, a guide assembly 700 is arranged between the drill rod 520 and the rotating sleeve 510. The guide assembly 700 includes a guide bar 710 and a guide groove 720. The guide bar 710 and the guide groove 720 both extend along the length direction of the rotating shaft, and the guide bar 710 and the guide groove 720 are slidably connected. Specifically, in this embodiment, the guide bar 710 is fixedly arranged on the inner side wall of the rotating sleeve 510, and the guide groove 720 is opened on the outer side wall of the drill rod 520. In other embodiments, the guide bar 710 can also be fixedly arranged on the outer side wall of the drill rod 520, and the guide groove 720 can be opened on the inner side wall of the rotating sleeve 510. Those skilled in the art can select the actual setting positions of the guide bar 710 and the guide groove 720 according to actual needs. Specifically, in this embodiment, the number of guide assemblies 700 is set to four, and the four guide assemblies 700 are arranged equidistantly around the central axis of the rotating sleeve 510. The guide assembly 700 is provided to enable the drill rod 520 to rotate along with the rotating sleeve 510 .

[0049] A spiral groove 521 is provided at the front end of the drill rod 520. By providing the spiral groove, when the drill rod 520 rotates with the rotating sleeve 510, it can achieve a function similar to a drill bit, so that the drill rod 520 can break the soil when drilling out, so that the drill rod 520 can be smoothly inserted into the soil.

[0050] The threaded sleeve 530 is fixedly connected to the insertion tube 300, and the threaded sleeve 530 is threadedly connected to the rear end of the drill rod 520 (the threaded structure of the threaded sleeve 530 and the rear end of the drill rod 520 is omitted in the figure and not shown). When the drill rod 520 rotates relative to the threaded sleeve 530, the drill rod 520 will move relative to the threaded sleeve 530 along the circumferential direction of the threaded sleeve 530, so that the drill rod 520 gradually moves away from the threaded sleeve 530, so that the drill rod 520 extends out of the main sleeve 100 from the drill rod perforation 110 and is inserted into the soil, so as to realize the action of the drill rod 520 rotating and moving in a straight line, so that the drill rod 520 can be smoothly inserted into the soil.

[0051] The specific use method of this rock and soil slope reinforcement device is:

[0052] Before inserting the present geotechnical slope reinforcement device, a hole for inserting the geotechnical slope reinforcement device is first drilled in the soil using other tools, and then the main sleeve 100 and the insertion head 200 are inserted into the hole. After the main sleeve 100 and the insertion head 200 are placed in place, the staff inserts the insertion tube 300 into the main sleeve 100. During the insertion of the insertion tube 300, the fixing nail 120 will be pushed to move in a direction away from the central axis of the main sleeve 100, so that the fixing nail 120 is inserted into the soil, which can enhance the anchoring effect of the present geotechnical slope reinforcement device to a certain extent. After the insertion tube 300 is installed in place, the staff uses a tool to connect with the wrench groove 410 of the drilling drive rod 400, and drives the drilling drive rod 400 to rotate through the tool. Since the drilling drive rod 400 is fixedly provided with a driving worm 420 and the rotating sleeve 510 is fixed with a driving worm gear 511, the rotating sleeve 510 will rotate around its own axis when the drilling drive rod 400 rotates. Since the drill rod 520 can rotate with the rotating sleeve 510, and the rear end of the drill rod 520 is threadedly connected to the fixed threaded sleeve 530, when the rotating sleeve 510 rotates, the drill rod 520 rotates with the rotating sleeve 510 and moves in the direction away from the threaded sleeve 530, so that the drill rod 520 passes through the main sleeve 100 from the drill rod hole 110 and is inserted into the soil. Since the movement of the drill rod 520 is to rotate and move forward, the spiral groove 521 at the front end of the drill rod 520 allows the drill rod 520 to cut the soil to a certain extent, so that the drill rod 520 can be more easily inserted into the soil, making the present rock and soil slope reinforcement device more suitable for harder soil, which is conducive to ensuring the anchoring effect of the present rock and soil slope reinforcement device.

[0053] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments.
