Hydraulically-driven shackle hook

Abstract

The invention relates to a hydraulically-driven shackle hook. The hydraulically-driven shackle hook comprises a hook body, a second bearing is mounted on the lower portion of a first bearing which is mounted at the top of the hook body, a bearing fixing device is connected with a hook fixing device which is connected with a hydraulic device fixing frame, a hydraulic device with a hydraulic cylinder is mounted on the hydraulic device fixing frame, and an electromagnetic valve is mounted on the hydraulic cylinder and connected with a storage battery and a wireless signal receiver. The hydraulic cylinder is connected with a connecting rod which is connected with a connection base, the hook fixing device is connected with a pulley block fixing frame, an anti-collision protective device is mounted at the top of the pulley block fixing frame, a pulley shaft is mounted on a pulley block which is mounted in the pulley block fixing frame, and the hook body is provided with an unhooking preventing protection device. The hydraulically-driven shackle hook has advantages of reasonable design, convenience in mounting and utilization, time saving, labor saving, high operation efficiency, realization of precision 90-degree rotation, effectiveness in rotation control, safety, reliability, wide application range and long service life.

Description

Technical field [0001] The invention belongs to the technical field of lifting equipment, and specifically relates to a hook, in particular to a hydraulic push-type rotary hook. Background technique [0002] With the rapid development of the national economy, the development of industrialization and the continuous progress of science and technology, cranes have been rapidly developed and widely used. Cranes are widely used in various fields of economic construction and are used more and more frequently and commonly. Various types of mines and oil fields have been explored. Crane hooks are an indispensable part of cranes. Common crane hooks consist of only one hook head. A single hook head cannot guarantee the balance of the lifting operation during the lifting operation. During the lifting process, the lifted objects are prone to sway in the air due to poor balance. In severe cases, they are prone to tilt, damage the objects and cause property losses. In order to compensate for t...

[0002] With the rapid development of the national economy, the development of industrialization and the continuous progress of science and technology, cranes have been rapidly developed and widely used. Cranes are widely used in various fields of economic construction and are used more and more frequently and widely. Our country continues to Various types of mines and oil fields have been explored. The hook of the crane is an indispensable part of the crane. The common crane hook consists of only one hook head. A single hook head cannot guarantee the balance of the lifting operation during the lifting operation. During the lifting process, due to the poor balance of the lifted items, it is easy to shake in the air. In severe cases, it is easy to cause the tilt of the lifted items, causing damage to the items and causing property losses. In order to make up for the shortcomings of single hooks, people invented The double-hook hook has a good balance effect, works smoothly, and increases the safety performance in the process of cargo lifting. Practice has proved that the use of the double-hook hook is better, and it is used in industrial production and large parts. During the assembly process, cranes are usually used to replace human work, which saves time, effort, and high work efficiency. Since some items need to complete a 90-degree rotation during the lifting process, for example, the installation of some large and complex parts requires relatively high assembly accuracy. High, in the process of using a crane to lift, the hook of the crane is required to complete a 90-degree rotation. At present, the rotation of the hook of the crane commonly used by people cannot be directly controlled. Rotation cannot meet the requirements of use. When using a crane to load and unload goods, it is often necessary to manually control the rotation of the hook to ensure the correct placement of the items. The labor intensity is high, time-consuming and laborious. When operating in some windy ports, manual There is a great risk in operating the rotation. In addition, during the working process of the crane, there will be accidents where the lifting objects fall off the hook, resulting in property loss. The anti-dropping of the crane hook is an important factor to ensure the safe lifting of the crane hook during the lifting process. Guarantee, in order to ensure the safe operation of the crane hook, the crane hook needs to be installed with an anti-decoupling device. Protection function, the built-in spring will lose its elastic function due to frequent stress, resulting in the device being unable to rebound and recover, losing the anti-unhook protection function, the tongue is easily deformed, falling off and losing its original protection function, the service life is short, and it is detached from the hook, resulting in The accident of decoupling when the crane is lifting the goods is easy to cause safety accidents, causing casualties and property losses, and there are potential safety hazards. Therefore, it is necessary to design a reasonable design, simple and compact structure, convenient installation and use, time-saving and labor-saving, anti-decoupling Good effect, high work efficiency, precise rotation of 90 degrees, good rotation control effect, stable lifting, safety and reliability, good economic benefits, wide application range and long service life are necessary for hydraulically driven rotary hooks. It is of great significance for the safe use and development of
