Hook for crane jib

Abstract

The invention discloses a hook for a crane jib. The hook for the crane jib comprises a hook and a connecting column, the top end of the hook goes through the central inner chamber of the connecting column and extends to the top end surface of the connecting column, the right sidewall of the connecting column is provided with an adjusting groove, a T-shaped storage groove is inwardly concavely formed in the right side of the bottom end surface of the connecting column, the T-shaped storage groove is communicated with the adjusting groove in a right-and-left manner, the inner chamber of the adjusting groove is in sliding clamping connection with a sliding block, the left end of the sliding block extends to the inner chamber of the T-shaped storage groove, an adjusting rod is fixedly welded to the left side of the bottom end surface of the sliding block, a limiting buckle is rotatably mounted at the bottom end of the adjusting rod, the tip of the bottom end of the hook integrally extendsto the bottom right to form a crotch, and the limiting buckle is adapted to the crotch. The hook for the crane jib makes the gap of the hook easily sealed to prevent looseness or slipping during working and reduce the danger coefficient, and is simple and practical.

Description

technical field [0001] The invention relates to the technical field of crane-related applications, in particular to a hook for a crane arm. Background technique [0002] In recent years, cranes have become an indispensable machine in the construction sites of large projects such as bridge construction and building construction, and hooks are the most common type of spreader in cranes. With the widespread use of cranes, their safety problems are also increasing. It has attracted attention. When various cranes are walking or transporting, the hook of the crane will return to the uppermost position. In the process of rising, the hook often shakes, causing safety hazards, and the hook on the traditional crane lacks anti-heavy weight. The device for falling off the object, when working, due to some accidental factors, the heavy object on the hook will be decoupled, which will not only cause a great accident, but also reduce the working efficiency and cannot meet the requirements,...

[0002] In recent years, cranes have become an indispensable machine in the construction sites of large projects such as bridge construction and building construction, and hooks are the most common type of spreader in cranes. With the widespread use of cranes, their safety problems are also increasing. It has attracted attention. When various cranes are walking or transporting, the hook of the crane will return to the uppermost position. In the process of rising, the hook often shakes, causing safety hazards, and the hook on the traditional crane lacks anti-heavy weight. The device for falling off the object, when working, due to some accidental factors, the heavy object on the hook will be decoupled, which will not only cause a great accident, but also reduce the working efficiency and cannot meet the requirements, so here is a design and production of a crane boom with hook for easy access
