A hanging assembly for an engineering crane

Abstract

The present invention provides a hanging component of an engineering crane, which relates to the technical field of hanging components, including: an installation mechanism; two groups of limit assemblies are arranged on the installation mechanism. During the hanging process, the crane drives the connecting piece to move upward, and the connecting piece pushes the support rod out of the inner groove through the transmission action of the gear group, and inserts it into the pipeline to hang the pipeline. After the hanging is completed, the main body is overlapped on the pipeline, and the pipeline supports the main body, so that the crane loses the force to pull the connecting piece upward, and the elastic piece pushes the connecting piece to shrink into the side groove. Through the transmission of the gear group, the support rod also shrinks into the inner groove, and the pipeline is detached from the sling at this time. Through such an arrangement, the sling can be automatically detached from the pipeline after the hanging is completed, which solves the problem that the hanging component of the traditional crane has an imperfect structure for fixing the pipeline. After the hanging is completed, it is necessary to manually remove the hanging component from the pipeline, which increases the labor of the construction personnel.

Description

Technical Field

[0001] The invention relates to the technical field of hanging components, in particular to a hanging component of an engineering crane. Background Art

[0002] During the construction process, a large number of pipes need to be installed. Since the pipes are heavy, they are not suitable for manual handling. Therefore, when installing the pipes, a crane is often required for lifting. By using hanging components, the pipes can be fixed to the crane during transportation.

[0003] For example, application number: CN201710863587.2 involves a buried pipeline lifting tool, including a hanger, and at least two loops fixed on the hanger, each loop has at least one end connected to the hanger in a detachable connection relationship, and after both ends of each loop are fixedly connected to the hanger, the space enclosed by all the loops and the hanger together constitutes the constraint space of the pipe section by this lifting tool; the loop is a multi-section combined structure, and the connection relationship between the rope segments constituting each loop is a detachable connection relationship. When this tool is used to lift a pipe section, the surface of the pipe section and the lifting tool will not be damaged due to friction, and the lifting safety of this tool is good.
