Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a hook machine parent and child clamp. Background Art

[0002] A crane is a machine widely used in construction projects. It is often used to dig foundations of buildings and factories, excavate soil, strip off the covering layer of mining sites, perform loading operations in quarries, tunnels, underground factories and stockpiles, dig channels, canals and dredge waterways, etc.; and after replacing the working device, it can perform pouring, lifting, installation, piling, tamping and other operations. With the increasing number of places of use, traditional cranes can no longer meet the construction needs, and the problem of slow efficiency has also emerged. Traditional cranes are easily affected by ground conditions when transporting strips or blocks of wood and stones. During transportation, the crane will shake irregularly due to the ground conditions. In addition, the bending degree of the crane's bucket is limited, and it cannot lift these strips or blocks of materials well. When the fuselage occurs When shaking, materials may easily fall. When encountering an environment with a bad geographical location, the falling and rolling of materials may indirectly cause property loss to others. When the crane is cleaning the river, it often carries garbage and water ashore. The water in the hook bucket is easily affected by the fuselage. When shaking, the water will fall together with the garbage in the crane, resulting in low construction efficiency. The crane cannot play its role in this regard. In order to solve the problem of the inconvenience of the crane in transporting goods, a thumb clip is welded on the side corresponding to the hook bucket to assist the crane in working. However, only one side of the hook bucket is moving, and the equipment is not flexible enough. There is still a risk of falling when transporting materials. When transporting materials, there may be situations where the materials need to be cut off, especially when encountering some relatively scattered materials, the hook bucket of the crane is not easy to cut off the materials.
