Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hook holding tooling, in particular to a hook holding tooling. Background Art
[0002] The hook is the most common type of lifting device in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism with the help of pulleys and other components. The hook is divided into single hook and double hook according to the shape; it is divided into forged hook and laminated hook according to the manufacturing method.
[0003] The hook tooling is used to hoist large-tonnage components. A single hook is prone to tearing when hoisting large components. Therefore, two hooks are strung together through round steel and welded together to form a hook. It is safer to hoist heavy components. However, welding two hooks together through round steel is only suitable for hoisting large-tonnage components, and long-term use will easily cause cracks or even cracks in the welding area.
[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content
[0005] In view of the above defects, the utility model provides a hook tool to solve the problem of hoisting the hook tool.

[0007] A hook tooling, comprising a group of hooks and round holes respectively opened at the upper ends of the group of hooks, wherein the group of hooks are connected by a detachable elastic locking mechanism;
[0008] The detachable elastic locking mechanism includes a connecting frame, a group of fixing rings, a group of conical elastic sleeves, a group of locking bolts, a connecting rod and a threaded sleeve. The connecting frame is sleeved on the outside of a group of hooks, a group of fixing rings are fixedly embedded on both sides of the bottom of the connecting frame, a group of conical elastic sleeves are inserted in a group of fixing rings, a group of locking bolts are suspended in a group of conical elastic sleeves, the connecting rod is installed at the bottom of the connecting frame, and the threaded sleeve is installed at the bottom of the connecting rod.
[0009] Furthermore, a group of inner ends of the tapered elastic sleeves are respectively provided with screw heads meshing with the threaded sleeves.
[0010] Furthermore, a group of locking bolts respectively include a conical head and a threaded rod, and a hexagonal head is arranged inside the conical head.
[0011] Furthermore, a group of conical elastic sleeves have a thread groove corresponding to the threaded rod on the inner bottom, and a group of conical elastic sleeves have a plurality of strip grooves evenly formed on the outer end surface.
[0012] Furthermore, a reinforcing plate is installed on the upper end of the connecting frame.
[0013] The utility model provides a hook tool, which has the following beneficial effects: the hook tool adopts a group of hooks connected by a detachable elastic locking mechanism. When a heavy component needs to be hoisted, a group of hooks can be combined, and when a light component needs to be hoisted, a group of hooks can be separated, which is convenient to use. The elastic locking is convenient for disassembly and assembly, and the hook connection is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1-5As shown: a hook tool, including a group of hooks 1 and round holes 2 respectively opened on the upper ends of the group of hooks 1, the group of hooks 1 are connected by a detachable elastic locking mechanism; the detachable elastic locking mechanism includes a connecting frame 3, a group of fixing rings 4, a group of conical elastic sleeves 5, a group of locking bolts 6, a connecting rod 7 and a threaded sleeve 8, the connecting frame 3 is sleeved on the outside of the group of hooks 1, a group of fixing rings 4 are fixedly embedded on both sides of the bottom of the connecting frame 3, a group of conical elastic sleeves 5 are inserted in a group of fixing rings 4, a group of locking bolts 6 are suspended and screwed on a group of conical elastic sleeves The connecting rod 7 is installed at the bottom of the connecting frame 3, and the threaded sleeve 8 is installed at the bottom of the connecting rod 7; a group of conical elastic sleeves 5 are respectively installed with screw heads 9 meshing with the threaded sleeve 8 at the inner ends; a group of locking bolts 6 include a conical head 10 and a threaded rod 11, and a hexagonal head 12 is arranged in the conical head 10; a group of conical elastic sleeves 5 are tapped with a threaded groove 13 corresponding to the threaded rod 11 at the inner bottom, and a group of conical elastic sleeves 5 are evenly opened with a plurality of strip grooves 14 on the outer end surface; a reinforcing plate 15 is installed at the upper end of the connecting frame 3.
