Technical Field

[0001] The utility model relates to the technical field of mining anchor rods, in particular to a mining anchor rod with a protective structure. Background Art

[0002] A mine anchor is an important tool used to support and reinforce mine tunnels, tunnels or mining working faces. It is usually made of metal or other materials and is used to fix and support rocks or soil to prevent collapse and collapse.

[0003] Publication No. CN208885318U discloses a self-locking anchor for mining, including an anchor body, a threaded bolt, a threaded sleeve, an anchor head, a connecting sleeve, a self-locking piece, a protrusion, a push rod, a spring, a side of each self-locking piece, a first locking nut, a second locking nut, a locking pin, a nut, a washer, a locking pin, and a nut. The utility model has a simple structure and is worth popularizing. Although this type of anchor rod has the effect of self-locking the anchor rod, it is lacking in the protection of the anchor rod. Since this type of anchor rod does not have a structure to protect the threaded section of the anchor rod, when the anchor rod is installed, the thread section of the anchor rod may be blocked or stuck with foreign objects, resulting in thread slippage, making it impossible to install or remove the anchor rod. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a mining anchor rod with a protective structure, comprising an anchor rod, a fixing plate is arranged on the surface of the anchor rod, a drill bit is fixedly installed on the surface of the anchor rod, a clamping block is fixedly installed on the surface of the anchor rod, a rotating block is arranged on the surface of the anchor rod, a sleeve is fixedly installed on the surface of the rotating block, a gasket is arranged on the surface of the sleeve, a buffer groove is penetrated through the surface of the sleeve, and an anti-sliding block is fixedly installed on the surface of the sleeve.

[0006] Preferably, the fixing plate is provided with an insert strip inside, and a cushion is fixedly installed on the surface of the fixing plate. Here, the insert strip design plays a role in fixing the fixing plate, preventing the fixing part from expanding after the anchor rod is fixed, thereby improving the fixing effect of the fixing plate.

[0007] Preferably, the rotating block is connected to the anchor rod by threads, and the sleeve is connected to the anchor rod by sliding. Here, the threaded connection design between the rotating block and the anchor rod drives the sleeve to slide on the anchor rod when the rotating block is rotated.

[0008] Preferably, the sleeve is slidably connected to the block, and the end of the block away from the drill bit is an arc surface. Here, the sliding design of the sleeve and the block has the effect of supporting the sleeve through the block and the buffer groove, so that the anti-sliding block and the sleeve are stuck on the inner wall of the fixing hole.

[0009] Preferably, the gasket is slidably connected to the sleeve, and the sleeve is slidably connected to the fixing plate. Here, the design of the gasket prevents the rotating block from getting stuck with the threaded section of the anchor rod when the rotating block is rotated, and the sliding design of the sleeve and the fixing plate has the effect of limiting the position of the sleeve when the sleeve slides.

[0010] Preferably, the insert is slidably connected to the fixing plate, and the cushion is made of natural rubber. Here, the sliding design of the insert and the fixing plate facilitates the reinforcement of the fixing plate through the insert, while the natural rubber material design of the cushion increases the sealing effect of the connection between the fixing plate and the fixing position.

[0012] 1. In the utility model, the sleeve, the rotating block, the gasket, the fixing plate, the clamping block, the buffer groove and the anti-sliding block are provided to protect the threaded section of the anchor rod, thereby avoiding the situation of thread slippage caused by the blockage of the threaded section of the anchor rod or the jamming of foreign objects, and at the same time, it also makes it easy to disassemble and assemble the anchor rod, and the structure is simple and practical.

[0013] 2. In the utility model, the fixing plate is fixed by providing the insert strips and the soft pads, so as to prevent the fixing position from expanding after the anchor rod is fixed, thereby improving the fixing effect of the fixing plate. At the same time, the design of the soft pads also increases the sealing effect of the connection between the fixing plate and the fixed position. BRIEF DESCRIPTION OF THE DRAWINGS
