Description

Technical Field

[0001] This utility model relates to the field of loess highway slope anchoring technology, specifically an anchor structure for loess highway slope anchoring. Background Technology

[0002] Loess highway slope anchoring bolts effectively improve slope stability and prevent disasters such as landslides and collapses through suspension, combination, compression, shear resistance, stress dispersion and overall enhancement. They also have advantages such as low cost and flexible construction, making them the core technology for highway slope reinforcement in loess areas. The existing anchor bolts are drilled into the loess slope using tools, and the threads are used to limit their movement within the loess slope. However, relying solely on the threads for fixation will eventually cause the anchor bolts to loosen due to vibration, thus reducing stability. To address the aforementioned shortcomings, the slope support anchor bolt authorized by announcement number CN209798747U, when used, has one end of the bolt fixedly connected to an electric drill. The drill is then started, and the bolt is drilled into the slope with the drill bit as the contact end, making it simpler and more effective. After the drill bit, bolt, and casing are inserted into the slope, the connection between the casing and the drill bit is loosened first. Then, while injecting concrete grout into the pouring space between the casing and the bolt, the casing is slowly pulled out. This effectively prevents gravel from entering the pouring space and improves the anchor bolt's anchoring force. This method improves both the efficiency of anchor bolt construction and the anchoring force of the bolt. In actual use, although the above-mentioned device can improve the stability of the anchor bolt, it is necessary to pour a concrete between the sleeve and the bolt before using the anchor bolt, which takes a long time before use and makes it inconvenient to use.

[0003] Therefore, we proposed an anchor structure for anchoring loess highway slopes that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an anchor structure for anchoring loess highway slopes, in order to solve the problem mentioned in the background art that the current market requires casting between the sleeve and the rod body, which leads to a long time before use and thus inconvenience.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: An anchor structure for anchoring loess highway slopes solves the problem that existing methods require casting between the sleeve and the anchor body, resulting in a long time required before use and thus inconvenience. The use of the limiting rod 5 improves the stability of the anchor body 1. The following is disclosed: The bottom of the anchor bolt body 1 extends into the interior of the loess highway slope; a positioning plate 2 is threadedly connected to the anchor bolt body 1, and a rotating rod 3 is rotatably connected inside the anchor bolt body 1. A gear 4 is keyed to the bottom of the rotating rod 3, and the gear 4 is located at the bottom of the anchor bolt body 1. The front and rear ends of the gear 4 are engaged with a limiting rod 5, and the limiting rod 5 is slidably connected inside the anchor bolt body 1. The limiting rod 5 fits into the interior of the anchor bolt body 1, and the outer end of the limiting rod 5 is housed inside the anchor bolt body 1. The inner end of the limiting rod 5 is provided with a toothed block, and the two sets of limiting rods 5 are arranged in opposite directions. refer to Figures 1 to 4 Using tools, the anchor bolt body 1 is inserted into the interior of the loess highway slope. Then, the positioning plate 2 is screwed into the anchor bolt body 1 through threads, so that the positioning plate 2 can play a limiting role. Then, the rotating rod 3 is rotated, so that the rotating rod 3 drives the gear 4 to rotate, and then the gear 4 drives the limiting rod 5 to move. This allows the limiting rod 5 to move inside the anchor bolt body 1, and then both sets of limiting rods 5 can extend out of the interior of the anchor bolt body 1 and into the interior of the loess highway slope, thereby further improving the stability of the connection between the anchor bolt body 1 and the loess highway slope, thus improving the ease of use.

[0017] Example 2: An anchor structure for anchoring loess highway slopes solves the problem of poor stability of the rotating rod 3 in Example 1. The stability of the rotating rod 3 can be improved by connecting the locking block 6 and the locking groove 7. The following is disclosed: A locking block 6 is slidably connected to the bottom of the top of the rotating rod 3, and the bottom of the locking block 6 extends into the interior of the locking groove 7 to form a locking mechanism. The locking groove 7 is opened at the top of the anchor rod body 1 at an equal angle, and the arc-shaped part of the locking groove 7 fits into the arc-shaped part of the locking block 6. The bottom of the locking block 6 is arc-shaped, and there are two sets of locking blocks 6. The arc-shaped positions of the two sets of locking blocks 6 are opposite. A spring 8 is connected to the top of the locking block 6, and the top of the spring 8 is connected to the top of the inside of the rotating rod 3 to form a limiting mechanism. refer to Figures 4 to 6 The rotation of the rotating rod 3 causes the locking block 6 to rotate, which in turn squeezes the locking block 6 against the locking groove 7. This squeezes the locking block 6 into the interior of the rotating rod 3, causing it to disengage from the locking groove 7. The movement of the locking block 6 also compresses the spring 8. After the rotating rod 3 reaches the desired position, the force of the spring 8 pushes the locking block 6 into the locking groove 7 to engage, thus fixing the position of the rotating rod 3. This improves the stability of the rotating rod 3 and prevents the limiting rod 5 from moving due to loosening.

[0018] Example 3: An anchor structure for anchoring loess highway slopes solves the problem of the rotating rod 3 not being easy to rotate in the reverse direction in Example 1. The use of the gripping block 9 facilitates the reset of the rotating rod 3. The following is disclosed: A gripping block 9 is fixed to the outer end of the locking block 6, and the gripping block 9 is fitted to the outer wall of the anchor rod body 1; refer to Figure 5 and Figure 6 When the limit rod 5 needs to be reset, the gripping block 9 is pulled, which causes the gripping block 9 to move and drive the locking block 6 to move. The locking block 6 then disengages from the locking groove 7 and squeezes the spring 8. The spring 8 is then compressed, so the rotating rod 3 can be rotated in the opposite direction using a tool. This allows the gear 4 to drive the limit rod 5 to reset, thus facilitating the anchor rod body 1 to detach from the loess highway slope.

[0019] Working principle: When using this type of anchor structure for anchoring loess highway slopes, firstly, refer to... Figures 1 to 4 Using tools, the anchor body 1 is inserted into the interior of the loess road slope. Then, the positioning plate 2 is screwed into the anchor body 1 through the thread, so that the positioning plate 2 can play a limiting role. Then, the gear 4 can drive the limiting rod 5 to move, and then the limiting rod 5 can move inside the anchor body 1, and then the limiting rod 5 can be inserted into the interior of the loess road slope, thus improving the convenience of use. refer to Figures 4 to 6 The rotating rod 3 rotates, causing the locking block 6 to rotate. The rotating locking block 6 can then press against the locking groove 7. The movement of the locking block 6 will also compress the spring 8. After the rotating rod 3 rotates to the desired position, the force of the spring 8 pushes the locking block 6 into the interior of the locking groove 7 to form a lock, thereby fixing the position of the rotating rod 3 and preventing the rotating rod 3 from loosening and causing the limiting rod 5 to move. refer to Figure 5 and Figure 6 When the limit rod 5 needs to be reset, the gripping block 9 is pulled, which causes the gripping block 9 to move and drive the locking block 6 to move. This causes the spring 8 to be compressed, so that the rotating rod 3 can be rotated in the opposite direction using a tool, which makes it easier for the anchor rod body 1 to detach from the loess highway slope.
