Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to an anchor rod waterproof device. Background Art

[0002] With the increase of coal mining depth and geological conditions, soft rock tunnel support is becoming more and more difficult. In recent years, cable anchor support has been widely used in developed mining countries such as the United Kingdom and Australia, and anchor support technology has developed rapidly, especially in slope management, traffic tunnels, hydropower and water conservancy, tunnel support, and construction foundation pits.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: after the device is inserted into the rock, the moisture in the rock will form water flow and fall into the locking clip. After a long time, the contact surface between the clip and the anchor rod will be corroded, so that the threads inside the clip cannot lock the anchor rod. For this reason, we propose an anchor rod waterproofing device that can prevent the water flow in the rock crack from falling into the clip and causing the clip to fail. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model provides an anchor rod waterproof device.

[0005] The utility model is implemented by the following technical scheme: an anchor rod waterproofing device, comprising an anchor assembly and an anchor rod, a tray assembly is installed on the top of the anchor rod, and the anchor assembly is used to fix the anchor rod, the anchor assembly comprises an anchor shell, the inner side of the anchor shell is threadedly connected to an anchor core, a clip assembly is arranged inside the anchor core, a rubber layer is fixedly connected to the top of the anchor core, the clip assembly comprises three clips, the bottoms of the clips are all fixedly connected to a fixing seat, a limiting groove is arranged on the surface of the fixing seat, and a limiting strip is arranged in the limiting groove.

[0006] As a further improvement of the above solution, the surface of the rubber layer is provided with an opening for the anchor rod to pass through.

[0007] As a further improvement of the above solution, the anchor shell is located between the rubber layer and the anchor inner core.

[0008] As a further improvement of the above solution, the bottom of the anchor shell abuts against the top of the fixing seat.

[0009] As a further improvement of the above solution, a sawtooth thread is provided on the inner side of the clip.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model arranges a rubber layer at the top of the inner core of the anchor, so that when the anchor rod passes through the rubber layer, the rubber layer can be closely attached to the surface of the anchor rod due to the ductility of the rubber, thereby preventing water in the rock crack from falling into the clip assembly, preventing the clip assembly from being corroded, and ensuring the locking effect of the device.

[0012] 2. The utility model improves the material of the clip and the tooth profile of the inner thread. The material is upgraded to an anti-corrosion alloy, and the tooth profile is changed from the original triangular thread to a serrated thread, thereby improving the corrosion resistance and locking ability of the device.

[0013] 3. The utility model avoids the loosening and misalignment of the clip during installation through the cooperation of the fixing seat and the limit strip at the bottom of the clip, thereby improving the convenience of installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Example:

[0021] Please combine Figure 1-3The present embodiment is an anchor rod 1 waterproof device, comprising an anchor assembly and an anchor rod 1, a tray assembly 2 is installed at the top of the anchor rod 1, the anchor assembly comprises an anchor shell 3, an anchor core 4 is threadedly connected to the inner side of the anchor shell 3, a rubber layer 5 is fixedly connected to the top of the anchor core 4, an opening for the anchor rod 1 to pass through is opened on the surface of the rubber layer 5, the opening on the surface of the rubber layer 5 is slightly smaller than the diameter of the anchor rod 1, so as to achieve a sealing effect, the anchor shell 3 is located between the rubber layer 5 and the anchor core 4, the bottom of the anchor shell 3 is in contact with the top of the fixing seat 7, and the anchor core 4 is fixedly connected to the top of the fixing seat 7. 4 is provided with a clip assembly, which includes three clips 6. The clips 6 are arranged in a cone shape. The bottoms of the clips 6 are fixedly connected to the fixing seats 7. The surfaces of the fixing seats 7 are provided with limiting grooves, and limiting strips 8 are arranged in the limiting grooves. When in use, the three clips 6 are closed, and the limiting strips 8 are wound in the limiting grooves of the fixing seats 7 to facilitate the use of the clip assembly. The inner side of the clips 6 is provided with a serrated thread. The serrated thread is provided to enhance the friction between the clips 6 and the anchor rod 1. The anchor inner core 4, the anchor outer shell 3, and the clips 6 are all made of anti-corrosion materials.

[0022] The implementation principle of a waterproof device for an anchor rod 1 in the embodiment of the present application is as follows: first, a hole is drilled at the designed position with an anchor drill, and then the anchor rod 1 is placed in the hole, the tray assembly 2 is installed on the anchor rod 1, and then the anchor core 4 is inserted into the anchor rod 1, and the rubber layer 5 on the top of the anchor core 4 enables the anchor core 4 to fit with the surface of the anchor rod 1 to prevent water from seeping in along the anchor rod 1. After fixing the anchor core 4, the anchor shell 3 is inserted into the anchor rod 1, and the anchor shell 3 is rotated so that the anchor shell 3 is threadedly connected to the surface of the anchor core 4, and three clips 6 are combined together, and the three clips 6 are fixed by the limit strip 8, and the clip assembly is inserted into the anchor rod 1 until the top of the fixing seat 7 abuts against the bottom of the anchor core 4, so that the rubber layer 5 can cover the anchor core 4 and the anchor shell 3, thereby improving the anti-water effect of the anchor.
