Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting hooks, in particular to a lifting hook for lifting equipment used for marine aquaculture. Background Art
[0002] The hook is the most common type of lifting equipment in lifting machinery. The hook is often hung on the wire rope of the lifting mechanism with the help of pulleys and other components. In marine aquaculture, the hook is used to lift large cargoes.
[0003] For example, the Chinese authorized patent (hook) with the announcement number CN210313165U includes a hook body, an anti-slip baffle and a reset spring. The anti-slip baffle is hinged to the hook body. The reset spring cooperates with the anti-slip baffle to make the anti-slip baffle pop up to close the opening of the hook body. It also includes a baffle pulling structure. The baffle pulling structure is hinged to the anti-slip baffle and extends to the rear of the hook body. The hook body supports the baffle pulling structure to prevent the baffle pulling structure from rotating downward. When the hard connector is removed from the hook, the baffle pulling structure is pulled by hand, and the anti-slip baffle swings downward. Then the hook can be removed by moving the hook. The hand-pulling baffle pulling structure is operated behind the hook, which is more convenient than manually pressing the anti-slip baffle in front of the hook; and during operation, the hand is hinged away from the hard connector and the heavy object, which can prevent the hand from touching the hard connector or the heavy object. This application is more suitable for hooks that are often connected to hard lifting connectors.
[0004] However, when the existing hook is hoisted, the friction of the rope is easy to shake, the positioning is poor, the stability is poor during hoisting, and the long-term back-and-forth friction is easy to cause large-scale damage to the surface coating of the hook, and the maintenance cost is high; therefore, it does not meet the existing needs. In this regard, we propose a hook for hoisting equipment for marine aquaculture. Utility Model Content
[0005] The purpose of the utility model is to provide a hook for hoisting equipment for marine aquaculture, so as to solve the problems of the existing hooks proposed in the above-mentioned background technology, that is, during hoisting, the friction of the rope is easy to shake, the positioning is poor, the stability is poor during hoisting, and the long-term back-and-forth friction is easy to cause large-scale damage to the surface coating of the hook, and the maintenance cost is high.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A hook for marine aquaculture lifting equipment, comprising: a hook body, one end of the hook body is provided with a fixed head, the other end of the hook body is provided with a hook tail, and the fixed head and the hook tail are all integrated with the hook body;

[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] 1. The utility model sets a positioning groove on the upper surface of the hook body at the arc position, and sprays a protective coating on the outer wall of the hook body. The protective coating consists of an anti-rust coating, a first anti-corrosion coating, a reinforcing layer and a second anti-corrosion coating. The hooks used for marine aquaculture are often in contact with seawater. The first anti-corrosion coating and the second anti-corrosion coating are used to improve the overall anti-corrosion effect, and the wear resistance is improved by the reinforcing layer. The friction with the rope is not easy to damage the hook, and when the hook and the rope are fixed, the rope is inserted into the positioning groove, which has a limiting effect on the rope, avoiding friction between the rope and other positions outside the positioning groove. In this way, the positioning groove is focused on during maintenance, and the cost of other positions will be less, thereby reducing the overall maintenance cost.

[0029] Support legs 9 are arranged on both sides of the lower end of the hook body 1, and two support legs 9 are arranged. The interior of the protective coating 10 is provided with an anti-rust paint 14, and the anti-rust paint 14 is sprayed on the outer surface of the hook body 1, and the outside of the anti-rust paint 14 is provided with a first anti-corrosion paint 15, and the outside of the first anti-corrosion paint 15 is provided with a reinforcement layer 16, and the reinforcement layer 16 is a metal wear-resistant coating, and the outside of the reinforcement layer 16 is provided with a second anti-corrosion paint 17, and the first anti-corrosion paint 15 and the second anti-corrosion paint 17 are both epoxy resin coatings.
[0030] When the hook body 1 is placed on the ground, the two supporting legs 9 support it upright and do not need to be placed flat on the ground, which avoids surface damage caused by friction with the ground during lifting, thereby improving protection and service life. The hooks used for marine aquaculture are often in contact with seawater. The first anti-corrosion coating 15 and the second anti-corrosion coating 17 improve the overall anti-corrosion effect, and the reinforcing layer 16 improves the wear resistance, so that the hook is not easily damaged by friction with the rope, and when the hook and the rope are fixed, the rope is inserted into the positioning groove 8, which has a limiting effect on the rope, avoiding friction between the rope and other positions outside the positioning groove 8, thereby reducing the overall maintenance cost.
[0031] See also Figure 2 , 3 The lower surface of the supporting leg 9 is provided with an anti-outward protrusion groove 11, and the anti-outward protrusion groove 11 and the supporting leg 9 are an integrated structure, one end of the anti-outward protrusion groove 11 is provided with a fixing bolt 12, and the lower surface of the hook body 1 is provided with a bolt groove 13, and one end of the fixing bolt 12 passes through the supporting leg 9 and is threadedly connected to the bolt groove 13, which is convenient for fixing and disassembling the supporting leg 9.

When the hook body 1 is placed on the ground, the two supporting legs 9 are used to support it upright, and it does not need to be placed flat on the ground, so as to avoid surface damage caused by friction with the ground during lifting, thereby improving protection and service life. In addition, the outside of the hook, including the supporting legs 9, is sprayed with anti-rust paint 14, a first anti-corrosion paint 15, a reinforcing layer 16 and a second anti-corrosion paint 17 in sequence. The hooks used for marine aquaculture are often in contact with seawater.
