In order to achieve the above object, the present utility model provides the following technical solutions:

the nut fastening auxiliary tool comprises a fixed ring, wherein a positioning pin and a fastening bolt are fixed on the outer side of the fixed ring, and the fastening bolt penetrates through the fixed ring to extend into the fixed ring.

Preferably, the plurality of positioning pins are fastened on the outer wall of the fixed ring through fixing nuts.

Preferably, at least one fastening bolt, the fastening bolt upper end all is equipped with the nut, and fastening bolt bottom passes fixation nut, solid fixed ring extension to solid fixed ring inside to be equipped with the kicking block.

Preferably, the inner wall of the fixing ring is provided with a convex rib, and two adjacent corners of the nut to be fastened are clamped on the convex rib.

Preferably, an elastic cambered surface friction block is arranged between two corners of the nut to be fastened, and the cambered surface of the cambered surface friction block is in contact with the inner wall of the fixed ring.

Advantageous effects

(1) The manufacturing materials are all materials commonly used in construction sites, the manufacturing materials are simple and easy to obtain, and the manufacturing process is simple;

(2) The nut tightening device is suitable for nut tightening operations with various specifications and sizes, does not need to replace a tightening head, has strong applicability, and is particularly suitable for large-size nut tightening operations;

(3) The structure is small and exquisite, and the device is suitable for an operation environment with a small space;

(4) The operation is simple, the working strength of constructors is reduced, and the processing efficiency is improved.

(5) The operation safety of constructors is ensured, and the practicability is high.

In the figure, 1-fixed ring, 2-locating pin, 3-fastening bolt, 31-nut, 4-fixed nut, 5-supporting block, 6-bead, 7-nut to be fastened, 8-cambered surface friction block and 9-steel tube.

Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1, the embodiment of the utility model provides an auxiliary tool for fastening nuts, which comprises a fixing ring 1, a locating pin 2, a fastening bolt 3, a nut 31, a fixing nut 4, a top support block 5, a convex rib 6, a cambered surface friction block 8 and other accessories. The fixing ring 1 is made of a round steel pipe, the thickness of the round steel pipe is 1-2CM, the side wall of the fixing ring 1 is provided with holes, and the aperture of the round steel pipe is matched with the aperture of the fastening bolt 3. The number of the positioning pins 2 is three, bolts can be adopted, the positioning pins are required to be uniformly distributed on the outer wall of the fixed ring, and the positioning pins are welded with the fixed ring. The positioning pin 2 should have a certain rigidity and strength and be insertable into the fixing ring 1 for operation. The fixing nut 4 is matched with the fastening bolt 3, and the fixing nut 4 is welded at the outer side open hole part of the side wall of the fixing ring.

At least one fastening bolt 3, the fastening bolt upper end all is equipped with nut 31, and fastening bolt 3 bottom passes fixation nut 4, solid fixed ring 1 extends to solid fixed ring 1 inside to be equipped with the top support piece 5.

The top support block 5 is a square steel plate and is welded at the end part of the fastening bolt; the top support block can also be screwed into the end part of the fastening bolt by adopting a nut matched with the fastening bolt. The function of the jacking block is to increase the contact surface with the nut to be fastened, so as to ensure the jacking effect of the fastening bolt.

The inner wall of the fixing ring 1 is provided with a convex rib 6, and two adjacent corners of the nut 7 to be fastened are clamped on the convex rib 6.

An elastic cambered surface friction block 8 is arranged between two corners of the nut 7 to be fastened, and the cambered surface of the cambered surface friction block 8 is in contact with the inner wall of the fixed ring 1.

In the concrete implementation, the nut 7 to be fastened is placed in the fixing ring, the top support block 5 is abutted against one edge of the nut 7 to be fastened by tightening the fastening bolt 3, and the fastening nut 7 is clamped; the thin fixing ring is then inserted over the locating pin 2 and the nut 7 to be fastened is tightened in place by screwing the thin steel tube 9. The utility model is applicable to the fixation of large nuts such as suspenders and foundation bolts, and it is conceivable that one end of the suspenders and foundation bolts used in cooperation with the nuts 7 to be fastened is fixed when the nuts are fixed.
