Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a hook for a bridge crane. Background Art

[0002] A bridge crane is a lifting device that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machinery.

[0003] The hook is an important component of the crane. The existing bridge crane hook has a fixed shape and size, but the fixed shape and size of the hook cannot be used to lift all objects. Therefore, when some special objects need to be lifted, the hook needs to be replaced. The traditional hook is very inconvenient to replace. Therefore, in order to quickly replace the crane hook, a bridge crane hook is proposed. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a hook for a bridge crane.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hook for a bridge crane, comprising a hook body, a stud fixedly connected to the top of the hook body, a screw sleeve threaded on the stud, a connecting column fixedly connected to the top of the screw sleeve, a connecting ring sleeved on the connecting column, the connecting ring fixedly connected to a mounting frame, four fixing blocks fixedly connected to the top of the mounting frame, each of the fixing blocks is provided with a lifting hole, connecting blocks are fixedly connected to the left and right sides of the hook body, and baffle rods are movably connected to the two connecting blocks.

[0006] Preferably, a torsion spring is arranged inside the baffle rod.

[0007] Preferably, the four fixing blocks are distributed in a circular array on the top of the mounting frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model can quickly dismantle the hook body and then replace it with a hook body of another style to meet different lifting requirements. The operation is simple and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0015] See also Figure 1-2 The utility model provides the following technical solutions: a hook for a bridge crane, comprising a hook body 1, a stud 10 is fixedly connected to the top of the hook body 1, a screw sleeve 9 is threadedly connected to the stud 10, a connecting column 8 is fixedly connected to the top of the screw sleeve 9, a connecting ring 7 is sleeved on the connecting column 8, the connecting ring 7 is fixedly connected to a mounting frame 6, four fixing blocks 4 are fixedly connected to the top of the mounting frame 6, each of the fixing blocks 4 is provided with a lifting hole 5, connecting blocks 3 are fixedly connected to the left and right sides of the hook body 1, and blocking rods 2 are movably connected to the two connecting blocks 3.

[0016] Specifically, a torsion spring is arranged in the blocking rod 2 , and one end of the torsion spring is connected to the connecting block 3 .

[0017] Specifically, the four fixing blocks 4 are distributed on the top of the mounting frame 6 in a circular array.

[0018] The working principle and use process of the utility model: when in use, the device is used in conjunction with a bridge crane, and the lifting holes 5 on each fixed block 4 can be passed through a lifting rope. Two lifting ropes or four lifting ropes can be selected for lifting according to needs. If two lifting ropes are selected, the lifting holes 5 through which the two lifting ropes pass need to be opposite to each other. After the lifting ropes passing through the lifting holes 5 are fixed, the device can be used to hang the goods. If the hook body 1 needs to be replaced, the hook body 1 only needs to be rotated to drive the stud 10 to disengage from the screw sleeve 9, the hook body 1 can be removed, and then the hook body 1 of other styles and sizes can be replaced.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
