The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0022] It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0023] See also Figure 1-3 The utility model relates to a hook, which has the advantages of low processing cost, high lifting safety and reusability, and can be widely used in the lifting of heavy objects such as box-type substations, containers, mobile houses, and flat cargo piles for centralized transportation of goods.

[0024] The hook comprises a mounting plate 10 , a pair of side plates 20 connected to both sides of the mounting plate, and a wire rope supporting plate 30 .

[0025] The mounting plate 10 is provided with a mounting hole 11 for passing a threaded connector through the mounting hole to be mounted on an object to be hoisted.

[0026] In one embodiment, the side plates 20 are formed by bending two opposite sides of the mounting plate 10 in the same direction, thereby enhancing the structural strength of the hook. Each side plate 20 is formed with a hook into which a wire rope can be placed to hoist an object.

[0027] The hook comprises a hook handle 21, a hook groove 22 and a hook plate 23. The hook groove 22 is an arc-shaped groove, and two ends thereof are connected to the hook handle 21 and the hook plate 23 respectively.

[0028] In one embodiment, the hook plate 23 extends in a direction away from the connection between the hook plate 23 and the hook groove 22, and in the projection on the mounting plate 10, the hook plate 23 covers a portion of the hook groove 22 and the hook handle 21, thereby providing a curved hook defined by a straight groove and a circular arc groove, wherein the straight groove serves as an entrance groove with a smaller diameter than the circular arc groove, thereby reducing the risk of the wire rope falling off the curved hook to a certain extent and improving the safety of lifting.

[0029] In one embodiment, the wire rope support plate 30 is connected to the two side plates 20 in the hook, and the wire rope support plate 30 is disposed in the hook groove and is located at the highest point of the hook groove 22 .

[0030] Since the hook is formed by the mounting plate 10 and the two side plates 20, the wire rope passes through the hooks of the two side plates, which can avoid the risk of being pulled obliquely or the wire rope coming out during the lifting process, and the safety is high. The hook is formed by processing the plate, the material is easy to obtain, the metal processing technology of fine turning is reduced, the processing is convenient, and the cost is low.

[0031] In addition, the hook is connected to the object to be lifted by a threaded connector. The connection structure is more reliable than welding and can be easily disassembled and assembled. The installation position can be changed to adjust the center of gravity of the lifted object. After use, the hook can be removed and reused, reducing the cost of hook manufacturing.

[0032] In addition, by arranging the steel wire rope support plate 30 to bridge the two hooks, the structural strength of the hook is enhanced, and the two side plates 20 are prevented from being deformed by the steel wire rope during the lifting process, thereby improving the lifting safety.

[0033] In one embodiment, the mounting plate 10 has a plurality of groups of mounting holes 11 distributed along its length direction, and each group of mounting holes 11 includes at least two mounting holes distributed along the width direction of the mounting plate.

[0034] In one embodiment, the hook further includes a reinforcing plate 40, which is connected between the two hook plates 23 to further enhance the structural strength of the hook and prevent the two side plates from being deformed due to stress.

[0035] In one embodiment, the end of the hook plate 23 is set to be semicircular and protrudes from the bottom edge of the reinforcing plate 40. By setting the end of the hook plate 23 to be semicircular, the hook plate 23 is prevented from scratching the wire rope.

[0036] In one embodiment, the side plate 20 is welded to the wire rope supporting plate 30 and the reinforcing plate 40 .

[0037] In one embodiment, the wire rope support plate 30 is provided with an arc-shaped embedding groove 31 matching with the wire rope.

[0038] In one embodiment, the arc-shaped embedding groove 31 is formed by bending a wire rope support plate.

[0039] By setting the arc-shaped embedding groove, the embedding groove cooperates with the wire rope to achieve the positioning of the wire rope, prevent the wire rope from moving in the hook groove, and prevent the hoisted object from tilting.

[0040] The technical solution provided by the utility model has the following beneficial effects: the hook of the utility model is formed by a mounting plate and two side plates, and the wire rope passes through the curved hooks of the two side plates, which can avoid the risk of being pulled obliquely or the wire rope coming out during the lifting process, and has high safety. The hook is formed by processing the plate, and the material is easy to obtain, which reduces the metal processing technology of fine turning, is convenient to process, and has low cost. In addition, the hook is connected to the object to be lifted by a threaded connector, which is more reliable than welding. The hook can be removed and reused after use, which reduces the cost of making the hook.
