Description
Technical Field
The invention relates to the field of lifting appliances, in particular to a large-scale steel pipe suspension claw.
Background
The weight of large steel pipes can reach dozens of tons generally, and after the steel pipes are produced in a workshop, subsequent processes such as painting, airing, maintenance and the like need to be carried out on the steel pipes. The existing method in a factory is to place the steel pipe on the bottom surface and realize painting, airing and the like by rolling, which causes surface damage to the large steel pipe and is inconvenient for workers to work.
Disclosure of Invention
The invention aims to provide a large steel pipe suspension claw which is further assembled into a suspension device, so that the large steel pipe can be suspended and hoisted, the surface damage of the large steel pipe is avoided, and meanwhile, the large steel pipe suspension claw is convenient for workers to work.
In order to achieve the purpose, the invention adopts the technical scheme that: a large-scale steel pipe hangs hook claw, it can form the large-scale steel pipe suspension device with bearing chain, fixing bolt, reinforcement nut, rings, hanging extension bar cooperation;
the hanging extension bar is a cylindrical steel extension bar, and the top and the bottom of the hanging extension bar are respectively provided with internal threads along the axial direction; the lifting ring is a steel ring, an external thread matched with the internal thread at the top of the hanging extension bar is arranged below the lifting ring, and the external thread and the lifting ring are integrally formed;
the suspension claw comprises an external thread part, a connecting disc and 4 claws; the external thread part is welded at the central position of the upper bottom surface of the connecting disc and is matched with the internal thread at the bottom of the hanging extension bar; the 4 hooks are arranged in a cross shape and are respectively welded on the lower bottom surface of the connecting disc, and the hook tips of the 4 hooks face to the outside;
the bearing chain is provided with 4 bearing chain pieces, one end of each bearing chain piece is hung on 4 hook claws, and the other end of each bearing chain piece is welded and fixed with the top of 1 fixing bolt; the fixing bolt is provided with an external thread which is matched and fixed with a threaded hole of the flange part of the large steel pipe; the reinforcing nut is matched with the fixing bolt and screwed to the bottom of the flange part from bottom to top.
Preferably, the hanging ring, the hanging extension bar and the hanging claw are cast by No. 45 steel.
The invention can stably and safely hoist the large steel pipe, has simple and convenient installation, does not need to punch holes on the steel pipe, and can not damage the outer surface of the steel pipe after hoisting. Workers can complete the work conveniently during paint spraying and maintenance.

the suspension claw 7 comprises an external thread part 8, a connecting disc 9 and 4 claws 10; the external thread part 8 is welded at the central position of the upper bottom surface of the connecting disc 9 and is matched with the internal thread at the bottom of the hanging extension bar 6; the 4 hooks 10 are arranged in a cross shape and are respectively welded on the lower bottom surface of the connecting disc 9, and the hook tips of the 4 hooks 10 face to the outside;
the bearing chain 2 has 4 pieces, one end of the bearing chain is hung on 4 hooks 10, and the other end of the bearing chain is welded and fixed with the top of 1 fixing bolt 3; the fixing bolt 3 is provided with an external thread which is matched and fixed with a threaded hole of the flange part 11 of the large steel pipe 1; the reinforcing nut 4 is matched with the fixing bolt 3 and screwed to the bottom of the flange part 11 from bottom to top.
Preferably, the hanging ring 5, the hanging extension bar 6 and the hanging claw 7 are cast from No. 45 steel.
When in use, the installation is carried out according to the following steps:
s1: screwing the fixing bolt 3 into a threaded hole on the flange part 11 of the large steel pipe 1, and screwing the reinforcing nut 4 to the bottom of the flange part 11 from bottom to top;
s2: hanging the top end of the bearing chain 2 on the hanging claw 7;
