Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, in particular to a safety hook rigging. Background Art
[0002] Hook rigging is a component of cargo rigging on ships, with a cargo hook at one end, mainly used to lift cargo. Cargo rigging refers to a set of rigging that hooks or grabs cargo and transmits the pulling force of the cargo winch to lift and lower cargo. It generally includes a hook device, pulley, cargo rope, and connecting parts such as shackles, eye plates, and rings. In the boom device, cargo rigging, jack rigging, and guy rigging are collectively referred to as cargo rigging. Cargo rigging is a component that directly bears the lifting load. The quality of its product is directly related to the safety of the lifting operation. The hook device is an important component of cargo rigging. It is generally composed of parts such as cargo hook, swivel, hook, shackle, weight and triangular eye plate, which are used to hook and lift cargo. The pulley, also known as the windlass, is a simple machine made according to the principle of leverage. It can save effort and change the magnitude and direction of the force. It is an important accessory for many lifting devices. Pulleys can be used individually or as a combination of multiple pulleys. They can be divided into many types according to their manufacturing materials, number of pulleys, structural characteristics, and lifting hook devices. With the development of society, hook rigging is used when goods need to be lifted.
[0003] Existing equipment, such as CN202337637U, a safety hook rigging, belongs to the field of mechanical design. This hook rigging includes a hook body and a lifting portion. The upper end of the lifting portion is a locking rod with a circular hole. The upper end of the hook body has a vertical slot, and the middle portion of the locking rod is clamped in the slot and connected to the hook body with rivets. A safety device is fixed in the vertical slot at the upper end of the hook body by an elastic cylindrical pin. A torsion spring is mounted on the elastic cylindrical pin. The ends of the torsion spring are supported on the hook body and the safety device, respectively. The safety device's boss is locked in the notch of the locking rod. During use, the safety device is pressed to release its boss from the notch of the locking rod, disengaging the safety device. The locking rod is then moved to disengage the lower end from the hook body and hook the rope. When lifting, a slight force is applied, and the lower end of the locking rod rebounds to the end of the hook body, closing the notch. At the same time, the safety device, under the action of the torsion spring, locks the locking rod.
[0004] When workers need to lift goods, they hang the goods on the hook sling so that the hook sling can lift the goods. However, when the hook sling is used for a long time in a harsh working environment, the locking device of the hook sling will be eroded by sea water, causing damage to the locking device of the hook sling. In addition, the goods will be affected by the wind during the lifting process and will shake and fall, which will threaten the life safety of the workers. Summary of the Invention
