Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 5, the present invention provides a hybrid hanger for concrete prefabricated parts, comprising a main lifting rope 1 connected to a hoist and a hanger 2 connected to the main lifting rope 1, folding suspension arms 3 are correspondingly arranged at the front side and the rear side of the two ends of the hanger 2, the folding suspension arms 3 are hinged with the hanger 2, torsion springs are arranged at the hinged parts of the folding suspension arms 3 and the hanger 2, namely, in the normal use process, the arranged folding suspension arm 3 can present a state of being attached under the acting force of the torsion spring, thereby avoiding the problem that the folding suspension arm 3 is easy to shake to affect the normal hoisting when hoisting the vertical member, the folding boom 3 is preferably connected with the hanger 2 through a hinge, and the hinge is fixed on the folding boom 3 and the hanger 2 through welding, so that the folding boom 3 and the hanger 2 can rotate freely, and the problem that the folding boom is easy to separate from each other can be avoided.
The folding suspension arm 3 and the hanger 2 are both provided with a plug socket 4 in the same vertical plane, the plug socket 4 arranged on the hanger 2 is fixedly provided with a main hoisting ring 5 connected with the main hoisting rope 1, the hanger 2 is connected with a lifting machine through the connection of the main hoisting ring 5 and the main hoisting rope 1, the main hoisting rope 1 is fixedly connected with an expansion hoisting rope 9 corresponding to the folding suspension arm 3, the folding suspension arm 3 is provided with an auxiliary hoisting ring 10 connected with the expansion hoisting rope 9, when the vertical component is hoisted, the gravity of the component is born through the main hoisting rope 1, when the folding suspension arm 3 is unfolded to hoist the horizontal component, the gravity of the component is born through the auxiliary hoisting rope 10 through the connection of the expansion hoisting rope 9 and the auxiliary hoisting ring 10, when the auxiliary hoisting rope 10 is used, the stress position of the vertical component is changed, so that the stress point of the vertical component is dispersed on the folding suspension arm 3, can guarantee that the horizontal component can be hoisted more stably.
What need supplement is that main rings and the bolt seat 4 formula structure as an organic whole of arranging on gallows 2 are mainly in order to guarantee that no matter what kind of form hoists, all can make extension lifting rope 9 and main lifting rope 1 carry out quick dismantlement and installation.
In addition, the end positions of the extension lifting rope 9 and the main lifting rope 1 are provided with safety latches, namely, the extension lifting rope 9 is connected with the auxiliary lifting ring 10 through the safety latches, the main lifting rope 1 is connected with the main lifting ring 5 through the safety latches, and the lifting form of the lifting appliance can be changed by a user more conveniently while the problem that the main lifting rope can fall off in the lifting process is avoided.
