The utility model discloses the technical problem that will solve is: the ring piece hoisting tool is high in hoisting efficiency and safe.
In order to solve the above problem, the utility model discloses the technical scheme who adopts does: ring piece lifts by crane frock, its characterized in that: the method comprises the following steps: the support ring, be provided with the several pull rods of arranging round the support ring in the top of support ring, the lower extreme of every pull rod all is connected with support ring upper portion, all be provided with on the upper end of every pull rod and hang the circle, be provided with the several jib of arranging round the support ring in the below of support ring, the upper end of every jib all is connected with the support ring lower part, all be provided with an L shape lifting hook that is used for hooking the ring piece in the below of every jib, the lower extreme of every jib all articulates with the top of corresponding L shape lifting hook mutually, all overlap on the upper end of every L shape lifting hook and be equipped with an antifriction ring.
Further, aforementioned ring piece lifts by crane frock, wherein: the antifriction ring is rotatably sleeved on the upper end of the L-shaped lifting hook through a bearing.
Further, aforementioned ring piece lifts by crane frock, wherein: the connecting structure of the lower end of the pull rod and the upper part of the support ring is as follows: the lower end of the pull rod is welded with an upper connecting ring, the upper part of the support ring is provided with an upper connecting hole, and the pull rod is connected with the upper part of the support ring through a shackle penetrating through the upper connecting ring and the upper connecting hole.
Further, aforementioned ring piece lifts by crane frock, wherein: the connecting structure of the upper end of the suspender and the lower part of the support ring is as follows: the welding has lower go-between on the upper end of jib, is provided with lower connecting hole on the lower part of support ring, and the jib is connected with the support ring lower part through the shackle that passes lower go-between and lower connecting hole.
Further, aforementioned ring piece lifts by crane frock, wherein: the tail end of the L-shaped lifting hook is provided with a limit boss which can prevent the ring piece from unhooking.
The utility model has the advantages that: the ring piece hoisting tool can hoist the ring piece without manual assistance, so that potential safety hazards can be eliminated, and the L-shaped lifting hooks can be evenly distributed on the periphery of the ring piece smoothly due to the arrangement of the antifriction ring, so that the hoisting efficiency can be greatly improved.

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
As shown in fig. 1, the ring hoisting tool comprises: the support ring 1, be provided with four pull rods 2 round the support ring 1 and arrange in the top of support ring 1, the lower extreme of every pull rod 2 all is connected with 1 upper portion of support ring, all be provided with on the upper end of every pull rod 2 and hang circle 21, be provided with four jib 3 round the support ring 1 and arrange in the below of support ring 1, the upper end of every jib 3 all is connected with 1 lower part of support ring, all be provided with an L shape lifting hook 4 that is used for hooking ring 9 in the below of every jib 3, the lower extreme of every jib 3 all articulates with the top of corresponding L shape lifting hook 4 mutually, all overlap on the upper end of every L shape lifting hook 4 and be equipped with an antifriction ring 5.
In this embodiment, an antifriction ring 5 is rotatably fitted on the upper end of the L-shaped hook 4 via a bearing.
In addition, the connecting structure of the lower end of the pull rod 2 and the upper part of the support ring 1 is as follows: an upper connecting ring 22 is welded at the lower end of the pull rod 2, an upper connecting hole 11 is arranged at the upper part of the support ring 1, and the pull rod 2 is connected with the upper part of the support ring 1 through a shackle 6 penetrating through the upper connecting ring 22 and the upper connecting hole 11. The connecting structure of the upper end of the suspender 3 and the lower part of the support ring 1 is as follows: the upper end of the suspender 3 is welded with a lower connecting ring 31, the lower part of the support ring 1 is provided with a lower connecting hole 12, and the suspender 3 is connected with the lower part of the support ring 1 through a shackle 6 which passes through the lower connecting ring 31 and the lower connecting hole 12.
A limit boss 41 which can prevent the ring piece 9 from unhooking is arranged at the tail end of the L-shaped lifting hook 4.
During hoisting, the hanging ring 21 at the upper end of each pull rod 2 is hung on a hanging hook of a travelling crane, so that the travelling crane can hang a ring hoisting tool, then the travelling crane drives the ring hoisting tool to move from the side surface to a ring stack stacked by a plurality of rings 9 until the ring hoisting tool moves right above the ring stack, in the moving process, each L-shaped hanging hook 4 can move along the ring stack in the circumferential direction and is basically uniformly distributed at the periphery of the ring stack, the friction force between the L-shaped hanging hook 4 and the rings can be reduced by the antifriction ring 5, the L-shaped hanging hook 4 can be prevented from moving along the ring stack due to overlarge friction force, and the friction force between the L-shaped hanging hook 4 and the rings can be further reduced after the antifriction ring 5 rotates; then the travelling crane drives the ring lifting tool to move upwards, and then the L-shaped lifting hooks 4 can be hooked below the ring pile, so that the ring lifting tool can lift the ring.
