Abstract

The invention provides a lifting appliance for lifting and a production machining method thereof. The lifting appliance for lifting comprises a blocking piece and a lifting portion. The lifting appliance for lifting is characterized in that the lifting portion is arranged to be an oval structure to be conveniently put into a semi-circular pin groove; a lifting through hole used for installation of a lifting hook is formed in the middle of the lifting portion; a lifting groove used for assembling pin heads is formed in the lower portion of the lifting portion; an assembling port is formed in one side of the lifting portion; and the pin heads enter the lifting groove through the assembling port, and the lifting portion rotates by a certain angle and is locked through the blocking piece. According to the lifting appliance for lifting, installation is convenient; the lifting appliance can rotate in the lifting process; stress concentration is small; the lifting appliance is locked automatically and does not unhook; safety is higher; the quality of products acquired through the production machining method of split type forging is better; and properties and the service life of the lifting appliance for lifting are improved.

Description

technical field [0001] The invention relates to the field of hanging and lifting, in particular to a hoisting sling and a production and processing method thereof. Background technique [0002] With the development of construction technology, the way of hoisting concrete prefabricated parts in the construction industry has also changed. Figure 5 As shown, the round-headed dowels are buried in advance in the concrete prefabricated parts, and the round-headed dowels are embedded in the concrete prefabricated parts as a whole. The corresponding positions of the concrete prefabricated parts are provided with semi-circular dowel grooves, and the heads of the round-headed dowels can be exposed, which are reserved for hanging. Assembly space, the suspender of the prior art is a hemispherical locking device, which blocks the head of the round pin and fixes it with bolts. This kind of spreader is inconvenient to install and unload, and the safety of bolt fixing is low, which affects...
