Description

Technical Field

[0001] This utility model relates to the field of grouting anchor technology, and more specifically to a grouting anchor protection structure for a high slope frame beam. Background Technology

[0002] During slope construction, in order to prevent landslides and protect the surrounding environment and work safety, slope protection is often required. Slopes are usually covered with protective nets, which are then fixed with anchor bolts. To ensure the stability of the anchor bolts, grouting anchor bolts are usually used for slopes with loose soil and rock. Traditional grouting anchor bolts for slope protection are first drilled into the slope surface with an anchor bolt drilling machine, and then the anchor bolts are inserted into the drilled holes.

[0003] An existing application (application number 202211148604.1) discloses a construction system for protecting the bottom end of a grouting anchor bolt. This system involves a construction device including an anchor bolt body. A circular baffle, a return spring, a circular support plate, and a limiting nut are sequentially fitted onto the bottom end of the anchor bolt body from top to bottom. The circular baffle is fixedly connected to the top of the bottom end of the anchor bolt body, and its bottom is fixedly connected to the top of the return spring. The limiting nut is fitted onto the outer wall of the bottom end of the anchor bolt body. A grouting pipe is also provided on one side of the anchor bolt body. Two limiting blocks are sequentially fixedly connected to the outer wall of the top of the bottom end of the grouting pipe from top to bottom. Both the circular baffle and the circular support plate have a grouting hole. Specifically, the grouting hole consists of a circular hole with an inner diameter the same as the outer diameter of the grouting pipe for the grouting pipe to pass through, and a limiting hole communicating with the circular hole for the limiting block below to pass through. This invention allows the bottom end of the anchor bolt to be fully encased in concrete, avoiding the defects of traditional anchor bolt grouting installation.

[0004] During use, when the anchor rod is subjected to large tension, the anchor rod may be pulled out as a whole, which is not conducive to slope protection and has poor performance. To address this issue, we propose a grouting anchor rod protection structure for high slope frame beams. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high slope frame beam grouting anchor protection structure to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a grouting anchor rod protection structure for a high slope frame beam, including a fixed cylinder, the side of the fixed cylinder is provided with grooves at equal intervals in an annular shape, each groove on the side of the fixed cylinder is provided with a swing arm, the inner wall of the fixed cylinder is provided with a sliding groove, the inner wall of the sliding groove is provided with a rack, the rack is fixedly connected to a limit post, and a tension spring is sleeved on the outer side of the limit post.

[0007] Wherein: a semi-ring gear is fixedly connected to the top of the inner side of each swing arm, and a fixed shaft is fixedly connected to the inner wall of each semi-ring gear through a bearing, and both ends of the fixed shaft are fixedly connected to the inner wall of the slide groove.

[0008] Preferably, a base is fixedly connected to the bottom end of the fixed cylinder, an mounting plate is fixedly connected to the top end of the fixed cylinder, a threaded block is fixedly connected to the inner wall of the mounting plate, and an internal thread groove is formed on the inner wall of the threaded block.

[0009] Preferably, the sides of the rack are meshed with the sides of the semi-ring gear, and a positioning rod is fixedly connected to the bottom end of the rack, the bottom end of the positioning rod being adapted to the bottom end of the slide groove.

[0010] Preferably, the top of the limiting post extends to the outside of the slide groove and is fixedly connected to a baffle, and the side of the limiting post is slidably connected to the top of the slide groove.

[0011] Preferably, the top end of each tension spring is fixedly connected to the top end of the inner wall of the groove, and the bottom end of each tension spring is fixedly connected to the top end of the rack.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model features swing arms. When using the device, the bottom end of the grouting anchor rod abuts against the upper surface of the baffle. As the grouting anchor rod continues to move downward, the baffle pushes the rack downward through the limiting pin. During the movement of the rack, it drives the swing arms through the semi-ring gear, causing them to rotate around the fixed axis. This opens the four swing arms, increasing the contact area between the bottom end of the grouting anchor rod and the hole wall, which helps to improve the protective effect of the device.

[0014] 2. This utility model uses a positioning rod that slides to the bottom of the inner wall of the groove to limit the rack, which helps to improve the stability of the device. The tension spring pulls the rack upward with its own tension, so that the rack pushes the grouting anchor rod upward through the limiting post, thus preventing it from loosening without external force, which further improves the stability of the device.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The high slope frame beam grouting anchor rod protection structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a grouting anchor protection structure for a high slope frame beam, including a fixed cylinder 1. The side of the fixed cylinder 1 is provided with grooves at equal intervals in an annular shape. A swing arm 2 is provided in each groove on the side of the fixed cylinder 1. A sliding groove 104 is provided on the inner wall of the fixed cylinder 1. A rack 3 is provided on the inner wall of the sliding groove 104. A limit post 4 is fixedly connected to the rack 3. A tension spring 5 is sleeved on the outer side of the limit post 4.

[0022] Specifically: the top of the inner side of each swing arm 2 is fixedly connected with a semi-ring gear 201, and the inner wall of each semi-ring gear 201 is fixedly connected with a bearing. Both ends of the semi-ring gear 201 are fixedly connected to the inner wall of the slide groove 104. In use, the rack 3 will drive the swing arm 2 through the semi-ring gear 201 during the movement of the swing arm 2, so that it rotates around the fixed shaft 202 as the axis, thereby opening the four swing arms 2, thereby increasing the contact area between the bottom end of the grouting anchor and the hole wall, thereby improving the stability of the grouting anchor.

[0023] Furthermore, a base 101 is fixedly connected to the bottom end of the fixed cylinder 1, and an installation plate 102 is fixedly connected to the top end of the fixed cylinder 1. A threaded block 103 is fixedly connected to the inner wall of the installation plate 102. The inner wall of the threaded block 103 is provided with an internal thread groove. Through the provided threaded block 103, during the installation process, the bottom end of the grouting anchor rod will be threadedly connected to the internal thread of the inner wall of the threaded block 103, thereby realizing the fixed connection between the device and the grouting anchor rod.

[0024] Furthermore, the sides of the rack 3 are meshed with the sides of the semi-ring gear 201, and a positioning rod 301 is fixedly connected to the bottom end of the rack 3. The bottom end of the positioning rod 301 is adapted to the bottom end of the slide groove 104. In use, the positioning rod 301 is slidably connected to the bottom end of the inner wall of the slide groove 104, thereby limiting the rack 3 and improving the stability of the device.

[0025] Furthermore, the top of the limiting post 4 extends to the outside of the slide groove 104 and is fixedly connected to a baffle 401. The side of the limiting post 4 is slidably connected to the top of the slide groove 104. In use, when the grouting anchor rod is inserted into the threaded block 103, the bottom end of the grouting anchor rod will abut against the upper surface of the baffle 401. As the grouting anchor rod continues to move downward, the baffle 401 will push the rack 3 downward through the limiting post 4, thereby causing the rack 3 to drive the swing arm 2 to open through the half ring gear 201, thus realizing the opening of the swing arm 2, which is beneficial to improving the protective effect of the device.

[0026] Furthermore, the top of each tension spring 5 is fixedly connected to the top of the inner wall of the slide groove 104, and the bottom of each tension spring 5 is fixedly connected to the top of the rack 3. In use, the tension spring 5 will pull the rack 3 upward through its own tension, thereby causing the rack 3 to exert an upward pushing force on the grouting anchor rod through the limiting post 4, thus preventing it from loosening without the action of external force, thereby improving the stability of the device.

[0027] The working principle of this utility model is as follows: In use, the bottom end of the grouting anchor rod is first inserted into the threaded block 103, and then the device is placed at the bottom of the hole. At this time, the grouting anchor rod is rotated, and the bottom end of the grouting anchor rod will abut against the upper surface of the baffle 401. As the grouting anchor rod continues to move downward, the baffle 401 will push the rack 3 downward through the limiting post 4. During the movement, the rack 3 will drive the swing arm 2 through the half ring gear 201, so that it rotates around the fixed shaft 202 as the axis, thereby opening the four swing arms 2, thereby increasing the contact area between the bottom end of the grouting anchor rod and the hole wall. Through the provided positioning rod 301, it is slidably connected to the bottom end of the inner wall of the groove 104, thereby limiting the rack 3 and improving the stability of the device. Through the provided tension spring 5, it will pull the rack 3 upward through its own tension, so that the rack 3 pushes the grouting anchor rod upward through the limiting post 4, thereby preventing it from loosening without the action of external force, thereby improving the stability of the device.
