Lifting hook structure capable of being unhooked and hooked automatically

Abstract

The invention discloses a lifting hook structure capable of being unhooked and hooked automatically. The lifting hook structure capable of being unhooked and hooked automatically comprises a lifting hook, a lifting mechanism and a lifting hook rotating driving device; the lifting hook comprises a lifting hook body and a lifting hook side plate; the lifting mechanism is connected with the lifting hook; the lifting mechanism comprises a scissors fork; the top fixed end of the scissors fork is fixedly connected with a base of the lifting mechanism; the scissors fork can control the freedom degreeof the lifting hook in the X direction and Y direction and can retract and stretch synchronously along with the ascending and descending of the lifting hook; the lifting hook rotating driving deviceis fixed to the lifting hook side plate; the lifting hook body is connected with the lifting hook rotating driving device through a hinge shaft; and the lifting hook rotating driving device can make the lifting hook body rotate around a rotating shaft which is connected with the lifting hook side plate, wherein the lifting mechanism drives the lifting hook to ascend and descend, the scissors forkcan ascend and descend synchronously, and meanwhile, a hook head of the lifting hook body can rotate out or rotate in from the lower part of a lifting ring arm under the action of the rotating drivingdevice, so that the lifting hook can be unhooked and hooked automatically. The lifting hook structure capable of being unhooked and hooked automatically disclosed by the invention is simple in structure and reasonable in design; and automatic lifting hook unhooking and hooking can be realized accurately.

Description

Technical field [0001] The invention belongs to the technical field of construction lifting equipment, and relates to an automatically detachable hook structure. Background technique [0002] In the lifting operation of building structural parts, the lifting and hooking of the spreader is an indispensable work. Usually, the lifting of the hook is done manually. Therefore, it is necessary to use a ladder to climb when the tall vertical component is hoisted, which has poor safety guarantee and low efficiency. If the hook removal can be done automatically instead of manual work, the efficiency and safety of hoisting operations will be greatly improved. At present, automatic lifting hook spreaders have been used in the field of standardized lifting such as container loading, but in the field of construction, the structural parts that need to be lifted are more complex and diverse, and no relevant equipment has been put into use. [0003] The information disclosed in the background se...
