An anchor bolt roughening device

Abstract

The invention discloses an anchor bolt roughening device, which comprises a mounting frame, a jacking head, a driving mechanism for driving the top head along the left and right directions, and a bolt automatic clamping mechanism; the driving mechanism is fixedly connected with the mounting frame, and the jacking head The fixed end is fixedly connected with the power output end of the driving mechanism; the bolt automatic clamping mechanism includes a housing, multiple clamping rods, a drive motor and a transmission mechanism for driving multiple clamping rods to expand and contract in the radial direction; multiple clamping rods The clamping rods are arranged in the circumferential direction, and the driving motor drives multiple clamping rods to expand and contract synchronously in the radial direction through the transmission mechanism; the transmission mechanism and the driving motor are arranged inside the housing, and the housing is fixedly connected with the mounting frame. The invention can automatically clamp the anchor bolts, thoroughly roughen the anchor bolts matching the nuts, and prevent the nuts from being stolen due to the lack of roughening or incomplete roughening of the anchor bolts, thereby ensuring the safety of the iron tower.

Description

Technical field [0001] The present invention relates to the field of ground bolts, and in particular, to a ground bolt hangup device. Background technique [0002] At present, after the construction site takes the nut fastened, it is necessary to make a flying bolt, so that the nut cannot fade, thus playing the anti-theft effect, the field method of leaking wire buckle, the field method is: use 10 pounds and above The hammer is hammered with the upper edge of the wire buckle, deduct the wire, thereby placing the outer edge of the leakage fastener to prevent the nut from falling off the stolen function. [0003] The existing hair method has the following questions: Hidden dangers. 2, using a large hammer to fill the upper edge of the floor bolt, so that the foot bolt is subjected to a large instantaneous impact, because the load impact effect can cause cracks between concrete and gentle bolts (such as the bending of the foot bolts) Moment, shear, lateral impact, etc.). 3. Because ...

AI Technical Summary

Problems solved by technology

[0003] The existing roughening methods have the following problems: 1. Using a sledgehammer to roughen the root of the upper part of the leaking threaded button cannot be roughened, and the part of the threaded button that has not been roughened can cause the nut to loosen, leaving a safety gap for the construction of the thread tightening process. Hidden danger

3. Because the iron tower and the foundation are always in the natural environment, rainwater will flow to the inside of the reinforced concrete along the cracks and gaps generated. During the oxidation process, the internal steel bars and ungalvanized anchor screws will be dry-corroded and expanded, which will reduce the life of the product. cycle, which also reduces the pullout capacity of the tower
