Problems solved by technology

However, because the metal rod body of the resin anchor rod is solidified by the resin in the anchor hole of the roadway and cannot be recovered, the metal rod body is easy to cause damage to the cutter of the excavator during the mining process of the roadway, or the collision between the two will generate sparks, which may cause a hidden danger of gas explosion.
In order to solve this problem, the patent No. 01265700.x provides a bonded recyclable anchor rod, which achieves the purpose of reclaiming the anchor rod by inserting a plastic sleeve on the metal rod body. The patent provides This kind of bonded recyclable bolt can only recycle the metal rod, but the plastic sleeve is thrown away in vain, resulting in a huge waste of materials

Embodiment Construction

[0014] The structure and operating principle of a fully recovered and reused anchor rod and its removal tool proposed by the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like figure 1 , 2 Shown is a structural schematic diagram of a fully recycled anchor rod, which includes a sleeve 1 made of elastic material (such as a steel plate), a metal rod body 2 that passes through the sleeve and has threads at both ends , the top of the sleeve 1 has (generally at least two, preferably three or) four such as image 3 Shown longitudinal groove 6, this longitudinal groove divides sleeve top part into four fins 8, and the depth of longitudinal groove 6 is equivalent to 1 / 4-1 / 3 (preferably 1 / 4) of sleeve length, and The inner wall of the other end of the sleeve 1 has a thread 9 roughly equivalent to 1 / 5 of its length. The bottom end of the metal rod body 2 passing through the sleeve is sleeved with a fixing nut 4...

Abstract

The invention relates to a fully recycle anchor pile and the removing tools. The main feature includes metal pile and the sleeve. The top screw thread of the metal pile is muffcoupling a nut and the bottom screw thread is mufcoupling a nut and stock. The inner wall of the sleeve has screw thread, and the removal tool is a screw that can rotate into the sleeve. The invention solves the problem that the sleeve left in the mine and wasted material.

Description

technical field [0001] The invention belongs to the technical field of coal mine roadway safety support, and in particular relates to a recoverable bolt and a removal tool thereof. Background technique [0002] At present, most of the safety support bolts installed in coal mines to prevent roadway collapse are pipe seam type, resin type, and cement type. Among them, resin bolts are widely used because of their large anchoring force and reliable performance. However, since the metal rod body of the resin anchor rod is solidified by the resin in the anchor hole of the roadway and cannot be recovered, the metal rod body is likely to cause damage to the cutter of the excavator or sparks caused by the collision of the two during the mining process of the roadway, which may cause a hidden danger of gas explosion. In order to solve this problem, the patent No. 01265700.x provides a bonded recyclable anchor rod, which achieves the purpose of reclaiming the an...
