Description

Technical Field

[0001] The utility model relates to the technical field of underground anchor cable installation, in particular to an auxiliary device for fixing an anchor cable wooden plug based on a rock drill. Background Technique

[0002] During the excavation of underground mines, it is inevitable to encounter poor geological conditions such as soft rock formations and fracture zones. To ensure mining safety, anchor cables are the mainstream support method. During the construction of anchor cables, especially for upward-hole anchor cables, the fixation of the anchor cable is the difficulty and key point of the construction. For upward-hole anchor cable construction, it is necessary to first complete drilling on the rock wall through a rock drill and insert the anchor cable. Subsequently, a wooden plug is used to seal the hole. The wooden plug is frustum-shaped, and the smaller-diameter end is used to insert into the rock hole. The wooden plug is provided with a grouting hole for the grouting pipe to pass through and an anchor cable hole for the anchor cable to pass through. After the wooden plug is stuffed into the hole and sealed, the anchor cable passes through the anchor cable hole and extends out, and the grouting pipe is inserted through the grouting hole for grouting.

[0003] In the prior art, usually the wooden plug is stuffed into the hole manually. Limited by the strength of the construction workers and the way of exerting force upward, if the wooden plug is not firm, it may be washed out under the influence of the grouting pressure, thus affecting construction safety. In the existing related patents, this problem has also been found and attempts have been made to strengthen the stability of the connection between the wooden plug and the rock hole. Most of them have made structural improvements to the anchor cable or the wooden plug to strengthen the anchor cable and the wooden plug. However, this type of improvement has increased the construction material cost. For example, the patent with the publication number CN208749381U discloses an anchor cable fixing device, which additionally installs a device on the anchor cable to enhance the stability. However, this device needs to be installed on each anchor cable, undoubtedly increasing the construction cost and construction time. Content of the Utility Model

[0004] In order to make the wooden plug be fixed more firmly on the rock hole, the present application provides an auxiliary device for fixing an anchor cable wooden plug.

[0005] The present application provides an auxiliary device for fixing an anchor cable wooden plug based on a rock drill, adopting the following technical scheme:

[0006] An auxiliary device for fixing an anchor cable wooden plug based on a rock drill includes a main body. The main body is a hollow cylinder. The top end of the main body is provided with a connection component for connecting the wooden plug, and the bottom end of the main body is for the drill bit of the rock drill to insert. The connection component includes a cylinder body. The cylinder body is a soft colloid, and the cylinder body wraps the large-diameter end of the wooden plug to connect with the wooden plug.

[0007] Optionally, the inner wall of the cylinder body is provided with sawteeth.

[0008] Optionally, the top end of the cylinder body is provided with a notch for the anchor cable to extend out.

[0009] Optionally, a flange is provided on the cylinder body, and a flange is also provided on the main body. The cylinder body and the main body are fixedly connected through the flange.

[0010] Optionally, the diameter of the main body gradually expands from the middle section to the top end.

[0011] In summary, the present application includes the following beneficial technical effects:

[0012] Through the setting of the connection component and the main body in the present application, both ends of the device can be respectively connected to the rock drill and the wooden plug. Subsequently, with the drilling force of the rock drill, the wooden plug is inserted into the rock hole to achieve a relatively stable effect. Then, the connection component can be separated from the wooden plug to carry out the subsequent grouting process. Compared with the existing manual method, it has greater strength, and the wooden plug is inserted more firmly. Compared with installing devices on the wooden plug or anchor cable, the device in the present application can be reused, and different-sized connection components can be replaced according to different specifications of the wooden plug, saving the construction material cost.

[0017] The following further describes the present application in detail with reference to the attached Figure 1-2 drawings.

[0018] The embodiment of the present application discloses an auxiliary device for fixing an anchor cable wooden plug based on a rock drill. The device includes a main body 1, and the main body 1 is composed of a plurality of steel pipes and steel rings spliced together. The main body 1 is in a cylindrical shape, and its diameter gradually increases from the middle section to the top end. At the same time, a connection component for connecting the wooden plug is provided at the top end, and a thread for connecting with the drill shaft of the drill is provided at the bottom end of the main body 1. It should be noted that there is already a thread for installing the drill bit on the drill shaft of the drill. The main body 1 can be firmly connected to the drill shaft by rotating and work with the drilling force of the drill.

[0019] The connection component includes a cylinder body 2. The cylinder body 2 is fixedly connected to the top end of the main body 1. The cylinder body 2 is a soft colloid, and when connecting with the wooden plug, it wraps a part of the large-diameter end of the wooden plug. In order to enhance the friction force, saw teeth 4 are provided on the inner wall of the cylinder body 2. At the same time, a notch 5 is provided on the cylinder body 2, and the anchor cable can extend out from the notch 5.

[0020] Considering that stoppers of different sizes are required for holes with different apertures, the cylinder body 2 and the main body 1 are designed as a split type. A flange 3 is provided on the cylinder body 2, and a flange 3 is also provided on the main body 1. The two flanges 3 are connected by bolts afterwards.

[0021] During use, the bottom end of the main body 1 is connected to the rock drill through threads. The stopper is connected to the cylinder body 2 so that the cylinder body 2 wraps a part of the large-diameter end of the stopper. The anchor cable extends out from the notch 5. Subsequently, the stopper is pushed into the hole by the rock drill. After the stopper is firm, the stopper is separated from the cylinder body 2. Since the cylinder body 2 is a soft colloid, the separation can be completed by simply pulling the cylinder body 2 by hand.

[0022] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
