Examples:

as shown in fig. 1 and 2, an open flange bucket hanging clamp comprises a load hook 1 and a lock hook 2, wherein the load hook 1 and the lock hook 2 are hinged through a clamp shaft 3. As can be seen from fig. 1, the load hook 1 in the present utility model is formed in one piece, the latch hook 2 is formed in two pieces, and the load hook 1 is built in the latch hook 2 to clamp the oil drum. In the prior art, the load hook is formed by two pieces, the lock hook is formed by one piece, the lock hook is arranged in the load hook, the crane is connected to the two pieces of load hooks in such a way, because the force applied by the crane is very large, the two pieces of load hooks are generally thinner than the two pieces of load hooks in one structure, and the two pieces of load hooks are sometimes broken due to insufficient strength.

As shown in fig. 3, the load hook 1 includes an upper branch 101 and a lower branch 102, the upper branch 101 and the lower branch 102 are fixedly connected at an obtuse angle, in this embodiment, the angle between the upper branch 101 and the lower branch 102 is 127 °, the obtuse angle is connected in such a way that the load hook 1 is in a shape with a large opening, when the oil drum is clamped, the load hook 1 is conveniently opened and closed, and in combination with fig. 2, the oil drum is tightly pressed by opening, i.e. clockwise rotation, and the oil drum is released by closing, i.e. anticlockwise rotation.

As shown in fig. 3, a connecting part 104 is fixed at the free end of the upper branch 101, wherein a connecting slot 105 is formed at the outer part of the connecting part 104, connecting holes 106 for connecting a crane shaft are formed at both side walls of the connecting slot 105, and when the crane shaft is connected, the crane shaft is placed in the connecting slot 105 and is connected with the connecting holes 106 by high-strength bolts.

As shown in fig. 3, the free end of the lower branch 102 is fixed with a load end plate 108, and in combination with fig. 2, the included angle between the load end plate 108 and the horizontal line is 67 °, the acute angle structure makes the load end plate 108 more convenient to contact with the oil drum, and the included angle set by 67 ° more accords with the specification of the large oil drum, and the load end plate is also applicable to the small oil drum, and the application range is wider.

As shown in fig. 2, the length of the load end plate 108 in the horizontal direction is smaller than the length of the connecting portion 104, so that the force application is more accurate when the oil drum is clamped.

As shown in fig. 4, the latch hook 2 includes two side wall plates 205 disposed in parallel, a support plate 206 fixed to one end of the two side wall plates 205, and a stopper plate 203 fixed to the other end of the two side wall plates 205; wherein the side wall plate 205 includes a lock body 201, a bent portion 202, and a hook portion 204; the bending part 202 is fixed at right angles to one end of the lock body 201, and the hook part 204 is fixed at the other end of the lock body 201; the stop plate 203 is fixed at the free ends of the two bending parts 202, and the inner side surface of the stop plate 203 is clamped on the inner wall of the upper end of the oil drum, and is used as the clamping surface of the inner wall of the oil drum, the inner side surface of the stop plate 203 is vertically arranged, as can be seen from fig. 2, the vertical state is matched with the inclined supporting plate 206 and the inclined load end plate 108, so that the clamping force is improved, and the clamping is more stable.

The load hook 1 is arranged in a gap formed between the two side wall plates 205, and the middle part of the load hook 1 is hinged with the middle parts of the two side wall plates 205; as shown in fig. 3, a convex load reinforcing part 109 is arranged at the joint of the upper branch 101 and the lower branch 102, a load shaft hole 103 is arranged at the joint, and the clamping shaft 3 is arranged in the load shaft hole 103 in a penetrating way; as shown in fig. 4, a convex latch hook reinforcing portion 210 is disposed at the connection between the bending portion 202 and the lock body 201, and a latch hook shaft hole 207 is disposed at the connection, and the clamp shaft 3 is disposed in the latch hook shaft hole 207 in a penetrating manner. In this embodiment, the strength of the location of the clip shaft 3 is improved by the load reinforcement 109 and the lock hook reinforcement 210, and since the load hook and the lock hook are connected by the clip shaft 3, the strength thereof affects the matching degree of the load hook and the lock hook.

As shown in fig. 4, in combination with fig. 2, the length of the hook portion 204 is smaller than the length of the bent portion 202, and further, the length of the hook portion 204 is short, so that in a free state, the position points of the three components of the stop plate 203, the load end plate 108 and the support plate 206 become a line with an obtuse angle, and the load end plate 108 is slightly recessed, so that the large oil drum can be adapted.

As shown in fig. 4, a stopper rod 208 is commonly fixed to the outer portions of the two side wall plates 205. The blocking lever 208 is fixed on the latch hook reinforcement portion 210, and referring to fig. 2, the blocking lever 208 is on the same line with the lock body 201, so that the blocking lever 208 can block the load hook 1 from the outside and limit the travel of the load hook 1 when the load hook 1 rotates with the latch hook 2. On the other hand, the stop plate 203 internally stops the travel of the load hook 1, so that the load hook 1 has a fixed travel range and cannot be separated or overturned.

A reinforcing rib 209 is fixed between the two lock bodies 201, so that the strength of the lock hook is further improved.

In this embodiment, as shown in fig. 2, the supporting plate 206 has an included angle of 80 ° with the horizontal line, and the purpose of adapting to various types of oil drums is achieved by matching with the 67 ° load end plate 108.

The inclined direction of the working surfaces of the load end plate 108 and the support plate 206 is downward.

Compared with the technical scheme that the lock hook 2 moves inside the load hook 1 in the prior art, the utility model adopts the technical scheme that the load hook 1 moves inside the lock hook 2, so that the strength of the whole oil drum lifting hook is improved, and the fracture condition is reduced.

The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model in any way, and any simple modification, equivalent variation and modification made to the above embodiments according to the technical principles of the present utility model are within the scope of the technical solutions of the present utility model.
