Description

Technical Field

[0001] The invention relates to the technical field of anchoring devices, in particular to an anchoring device used for preventing landslides under soft soil conditions. 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. However, the contact area between the rod-shaped structures and the soil is small. When the anchoring device is pulled out, the force exerted by the soil on the rod-shaped structures is weak, and it cannot have a good fixing effect on soft soil. The anchoring device is easily pulled out, and the anchoring effect of the anchoring device is reduced. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an anchoring device for preventing landslides under soft soil conditions, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0006] The solution of the present invention to solve its technical problem is:

[0007] An anchoring device for preventing landslides under soft soil conditions, comprising:

[0008] Main sleeve;

[0009] an insertion head, the insertion head being rotatable relative to the main sleeve, the insertion head being provided with a threaded portion;

[0010] A movable sleeve, the movable sleeve being threadedly connected to the threaded portion, and the movable sleeve slides up and down relative to the main sleeve;

[0011] A rotating sleeve, the rotating sleeve is rotatably connected to the movable sleeve, and the rotating sleeve rotates along with the insertion head;

[0012] An expansion plate, the expansion plate is located outside the main sleeve, and the lower end of the expansion plate is hinged to the insertion head so that the expansion plate can swing relative to the insertion head;

[0013] A first connecting rod, two ends of which are respectively hinged to the middle of the expansion plate and the rotating sleeve;

[0014] When the insertion head rotates in the forward direction, the expansion plate rotates in the forward direction and swings in the direction away from the main sleeve.

[0015] As a further improvement of the above technical solution, a telescopic connecting rod is provided between the insertion head and the rotating sleeve, the distance between the two ends of the telescopic connecting rod is adjustable, and the two ends of the telescopic connecting rod are fixedly connected to the insertion head and the rotating sleeve respectively.

[0016] As a further improvement of the above technical solution, there are multiple telescopic connecting rods, and the multiple telescopic connecting rods are arranged at intervals around the rotation axis of the insertion head.

[0017] As a further improvement of the above technical solution, the expansion plate is provided with a first wedge, and the first wedge is located at the front end of the expansion plate in the positive rotation direction.

[0018] As a further improvement of the above technical solution, from the inner side of the expansion plate to the outer side of the expansion plate, the first wedge gradually inclines toward a side away from the main sleeve.

[0019] As a further improvement of the above technical solution, the expansion plate is provided with a second wedge, and the second wedge is located at the rear end of the expansion plate in the positive rotation direction.

[0020] As a further improvement of the above technical solution, from the inner side of the expansion plate to the outer side of the expansion plate, the second wedge gradually inclines toward a side close to the main sleeve.

[0021] As a further improvement of the above technical solution, a reinforcing rib structure is provided on a side of the expansion plate facing the main sleeve.

[0022] As a further improvement of the above technical solution, the reinforcing rib structure includes transverse reinforcing ribs and vertical reinforcing ribs. The transverse reinforcing ribs are arranged perpendicular to the vertical reinforcing ribs. There are multiple transverse reinforcing ribs, and the multiple transverse reinforcing ribs are arranged at intervals along the length direction of the expansion plate.

[0023] As a further improvement of the above technical solution, the upper end of the main sleeve is detachably connected with a fixing plate, and the fixing plate is used to preliminarily fix the main sleeve to the ground.

[0024] The beneficial effect of the present invention is that the staff first drills a hole at the location where the anchor device needs to be installed, and then places the anchor device into the hole. After the anchor device is placed in place, the staff uses a tool to drive the threaded portion to rotate forward, and the threaded portion drives the insertion head to rotate forward. During the forward rotation of the insertion head, due to the existence of the telescopic connecting rod, the rotating sleeve will rotate forward with the insertion head, and at the same time, the moving sleeve will move downward. During the downward movement of the moving sleeve, the first connecting rod will drive the expansion plate to gradually move in a direction away from the main sleeve, so that the expansion plate gradually swings downward during the forward rotation.

[0025] When the expansion plate is fully unfolded, the contact area between the expansion plate and the soil is larger. When the anchor device is pulled out, the soil will produce greater resistance to the expansion plate, thereby improving the anti-pullout performance of the anchor device, which can effectively improve the installation firmness of the anchor device and the soil, and can effectively improve the anchoring effect of the anchor device.

[0026] The invention is used in the technical field of anchoring devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The main sleeve 100 is a cylindrical structure, which is made by splicing and welding two components. The side wall of the main sleeve 100 is provided with four through holes, which are arranged equidistantly around the central axis of the main sleeve 100. The four through holes are used for other components to pass through. The main sleeve 100 is set as a structure formed by splicing two components, so that other components can be installed in the main sleeve 100, and part of the structure of other components can pass through the main sleeve 100 through the through holes.

[0036] Specifically, in this embodiment, the upper end of the main sleeve 100 is detachably connected to a fixing plate 110. When inserting the anchoring device, the fixing plate 110 is first fixed to the upper end of the main sleeve 100, and then the staff fixes the fixing plate 110 with their feet or nails. This can prevent the main sleeve 100 from rotating during the subsequent installation of the anchoring device, thereby ensuring that the anchoring device can be installed normally.

[0037] The insertion head 200 is arranged below the main sleeve 100, and the insertion head 200 is rotatably connected to the lower end of the main sleeve 100. Naturally, a limiting structure is arranged between the insertion head 200 and the main sleeve 100, and the limiting structure enables the insertion head 200 to move along the up and down directions with the main sleeve 100. Specifically, the limiting structure includes a rotating flange 120 and a rotating groove 221. The rotating flange 120 is fixedly arranged at the lower end of the main sleeve 100, and the rotating groove 221 is opened in the insertion head 200. The rotating flange 120 is arranged in the rotating groove 221 and is rotatably connected to the rotating groove 221.

[0038] Specifically, in this embodiment, the insertion head 200 includes a first split structure 210, a second split structure 220 and a connection structure 230. The first split structure 210 is provided with a sleeve insertion groove 211 and a split connection groove 212, the lower end of the main sleeve 100 is inserted into the sleeve insertion groove 211, the lower end of the second split structure 220 is inserted into the sleeve insertion groove 211 and the split connection groove 212, the side wall of the second split structure 220 abuts against the inner wall of the main sleeve 100, the rotation groove 221 is provided at the lower end of the second split structure 220, and the rotation flange 120 is provided in the rotation groove 221. The connection structure 230 is provided as a screw, and the connection structure 230 passes through the first split structure 210 and is threadedly connected with the second split structure 220, so as to achieve the fixation of the first split structure 210 and the second split structure 220. The first split structure 210 , the second split structure 220 and the connection structure 230 may enable the insertion head 200 and the main sleeve 100 to be installed and connected.

[0039] Specifically, the insertion head 200 is provided with a threaded portion 201, which is provided on the second split structure 220. The threaded portion 201 is a threaded rod extending upward. The upper end of the threaded portion 201 is provided with a wrench groove for cooperating with a tool. When the tool is inserted into the wrench groove, the insertion head 200 can be driven to rotate by the tool.

[0040] The movable sleeve 300 is arranged on the inner side of the main sleeve 100. The movable sleeve 300 can move in the up and down directions relative to the main sleeve 100. The movable sleeve 300 is sleeved on the threaded portion 201 and is threadedly connected with the threaded portion 201. The movable sleeve 300 is provided with an extension portion, which passes through the outlet hole of the main sleeve 100 and extends out of the main sleeve 100.

[0041] In this embodiment, when the insertion head 200 rotates forward, the movable sleeve 300 moves downward because the movable sleeve 300 is threadedly connected to the threaded portion 201. In other embodiments, it can also be arranged that when the insertion head 200 rotates forward, the movable sleeve 300 moves upward. Those skilled in the art can select the thread rotation direction of the threaded portion 201 and the movable sleeve 300 according to actual needs.

[0042] The rotating sleeve 400 is rotatably connected to the portion of the moving sleeve 300 extending out of the main sleeve 100 so that the rotating sleeve 400 can move up and down together with the moving sleeve 300.

[0043] Specifically, in this embodiment, a telescopic connecting rod is provided between the rotating sleeve 400 and the insertion head 200, and the distance between the two ends of the telescopic connecting rod is adjustable. Specifically, the telescopic connecting rod includes a telescopic rod and a telescopic sleeve, the telescopic sleeve is sleeved on the telescopic rod, the telescopic sleeve and the telescopic rod are slidably connected in the up-down direction, the lower end of the telescopic sleeve is fixedly connected to the insertion head 200, and the upper end of the telescopic rod is fixedly connected to the rotating sleeve 400. Through the telescopic connecting rod, the rotating sleeve 400 can rotate with the insertion head 200.

[0044] Specifically, in this embodiment, the number of telescopic links is set to four, and the four telescopic links are equidistantly arranged around the circumference of the rotation axis of the insertion head 200. In other embodiments, the number of telescopic links may be set to three, five, six, etc., and those skilled in the art may select the number of telescopic links according to actual needs.

[0045] The number of expansion plates 500 is set to be multiple, and the multiple expansion plates 500 are arranged equidistantly around the rotation axis of the insertion head 200, and the expansion plates 500 are arranged on the outside of the main sleeve 100. The lower end of the expansion plate 500 is hingedly connected to the insertion head 200, and the swing axis of the expansion plate 500 is parallel to the width direction of the expansion plate 500, so that the expansion plate 500 can swing relative to the insertion head 200 in a direction close to the main sleeve 100 or away from the main sleeve 100.

[0046] The first connecting rod 600 is disposed between the rotating sleeve 400 and the expansion plate 500, and the two ends of the first connecting rod 600 are respectively hingedly connected to the rotating sleeve 400 and the middle of the expansion plate 500. Specifically, in this embodiment, the lower end of the first connecting rod 600 is hingedly connected to the middle of the expansion plate 500, and the upper end of the first connecting rod 600 is hingedly connected to the rotating sleeve 400, so that when the rotating sleeve 400 moves downward with the moving sleeve 300, the first connecting rod 600 gradually tilts, pushing the expansion plate 500 to swing in a direction away from the main sleeve 100.

[0047] In other embodiments, the lower end of the first connecting rod 600 can be hinged to the rotating sleeve 400, and the upper end of the first connecting rod 600 can be hinged to the middle of the expansion plate 500, so that the rotating sleeve 400 moves upward when the insertion head 200 rotates forward, and the first connecting rod 600 is pushed to swing in a direction away from the main sleeve 100.

[0048] Specifically, in this embodiment, the two edges of the first connecting rod 600 arranged along the positive rotation direction are both provided with drag reducing wedges 610. By providing the drag reducing wedges 610, when the first connecting rod 600 rotates with the rotating sleeve 400 and the insertion head 200, the resistance caused by the soil to the first connecting rod 600 can be reduced.

[0049] Specifically, in this embodiment, the expansion plate 500 is provided with a first wedge 510 and a second wedge 520, the first wedge 510 is located at the front end of the expansion plate 500 in the forward rotation direction, and the second wedge 520 is located at the rear end of the expansion plate 500 in the forward rotation direction, that is, the first wedge 510 and the second wedge 520 are arranged along the forward rotation direction, and in the forward rotation direction, the first wedge 510 is arranged in front of the second wedge 520. The function of the first wedge 510 is to reduce the resistance of the soil to the expansion plate 500 when the expansion plate 500 rotates forward. The function of the second wedge 520 is to reduce the resistance of the soil to the expansion plate 500 when the expansion plate 500 rotates reversely.

[0050] Specifically, in the present embodiment, from the inner side of the expansion plate 500 to the outer side of the expansion plate 500 (along the width direction of the expansion plate 500), the first wedge 510 gradually tilts toward the side away from the main sleeve 100. Since the expansion plate 500 will swing while rotating, the inclined surface of the first wedge 510 is set to face the main sleeve 100. The component of the force generated by the soil on the first wedge 510 and the expansion plate 500 points in the direction away from the main sleeve 100, which can reduce the resistance of the soil to the swinging of the expansion plate 500, so that the expansion plate 500 is easier to unfold when the expansion plate 500 rotates in the forward direction.

[0051] Specifically, in the present embodiment, from the inner side of the expansion plate 500 to the outer side of the expansion plate 500 (along the width direction of the expansion plate 500), the second wedge 520 gradually tilts toward the side close to the main sleeve 100, and the inclined surface of the second wedge 520 is set to face away from the main sleeve 100. The component force of the force exerted by the soil on the second wedge 520 and the expansion plate 500 points in the direction close to the main sleeve 100, which can reduce the resistance of the soil to the swinging of the expansion plate 500, so that the expansion plate 500 can be more easily retracted when the expansion plate 500 rotates in the opposite direction.

[0052] Specifically, in this embodiment, the expansion plate 500 is provided with a reinforcing rib structure 530, and the reinforcing rib structure 530 is arranged on the side of the expansion plate 500 facing the main sleeve 100. Specifically, the expansion plate 500 includes vertical reinforcing ribs 531 and transverse reinforcing ribs 532, the vertical reinforcing ribs 531 and the transverse reinforcing ribs 532 are arranged perpendicularly, the number of the vertical reinforcing ribs 531 and the transverse reinforcing ribs 532 are both set to multiple, the multiple vertical reinforcing ribs 531 are arranged at equal intervals along the width direction of the expansion plate 500, and the multiple transverse reinforcing ribs 532 are arranged at equal intervals along the length direction of the expansion plate 500.

[0053] The implementation principle of this scheme is as follows: the staff first drills a hole at the location where the anchoring device needs to be installed, and then places the anchoring device into the hole. After the anchoring device is in place, the staff fixes the main sleeve 100 to the soil through the fixing plate 110, and then the staff uses a tool to drive the threaded portion 201 to rotate forward, and the threaded portion 201 will drive the insertion head 200 to rotate forward. During the forward rotation of the insertion head 200, due to the presence of the telescopic connecting rod, the rotating sleeve 400 will rotate forward with the insertion head 200. At the same time, the movable sleeve 300 will move downward. During the downward movement of the movable sleeve 300, the first connecting rod 600 will drive the expansion plate 500 to gradually move away from the main sleeve 100, so that the expansion plate 500 gradually swings downward during the forward rotation.

[0054] When the expansion plate 500 is fully unfolded, the contact area between the expansion plate 500 and the soil is larger. When the anchor device is pulled out, the soil will produce greater resistance to the expansion plate 500, thereby improving the anti-pullout performance of the anchor device, which can effectively improve the installation firmness of the anchor device and the soil, and can effectively improve the anchoring effect of the anchor device.

[0055] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments.
