Internal rotation type recyclable anchor rod with built-in anchoring rod

Abstract

The invention relates to an internal rotation type recyclable anchor rod with a built-in anchoring rod, and belongs to the technical field of anchor rods. The anchor rod comprises a main rod, an anchor head and a rotating rod, a tapered roller bearing is arranged at the front end of the rotating rod, two anchor flukes hinged together through a rotating shaft are arranged at the front end of the anchor head, and the tail ends of the two anchor flukes are fixedly connected with the tapered roller bearing at the front end of the rotating rod; a plurality of ball bearings are fixedly arranged on the inner wall of the main rod, the two coordination rods are arranged above and below the rotating rod through the ball bearings respectively, a gear section is arranged at the middle end of the rotating rod, a plurality of pinions corresponding to the gear section are arranged on the two coordination rods at intervals, and a plurality of anchoring rods are connected between the gear section of the rotating rod and the pinions of the two coordination rods. A plurality of holes corresponding to the anchoring rods are formed in the main rod body; the middle rear end of the rotating rod is further provided with a rotating baffle, the two coordination rods are provided with large gears matched with the rotating baffle, and the anchoring rod conducts anchoring along a hole formed in the rod body of the main rod under the cooperation of the rotating rod and the coordination rods. Grouting is not needed, and recycling is easy.

Description

technical field [0001] The invention relates to an inner-rotating built-in anchor rod and a recoverable anchor rod, which belongs to the technical field of anchor rods. Background technique [0002] Anchor rods are rock-soil reinforcement rod systems, and are widely used in surface engineering such as slopes, deep geotechnical foundation pits, tunnels, and stopes. At present, the commonly used soil slope anchoring methods are difficult to achieve complete recovery of the bolts. Usually, after the project is completed, the rods or part of the rods cannot be recovered and are buried underground, which not only increases the construction difficulty of other surrounding buildings, but also It causes a great waste of materials, and also causes "pollution" to the underground space, and the economic benefits are poor. [0003] Many experts and scholars have studied the above problems and developed many different forms of recyclable bolts. However, there are still some problems in ...
