Description
Technical Field
The invention relates to the technical upgrading of a tower crane hook of hoisting equipment, in particular to a tower crane hook with automatic zooming function between two ropes and four ropes.
Background
In the tower crane operation engineering, the higher the hoisting height is, the longer the hoisting process is, the lower the hoisting speed is, the shorter the hoisting height is, the faster the hoisting speed is, and the inverse relationship is formed between the hoisting height and the hoisting speed. The longer the length of a lifting rope on a lifting hook for retracting and releasing a winch on a crane boom is, the longer the hoisting process is; the shorter the length of the lifting rope on the retractable lifting hook is, the shorter the lifting process is.
At present, a crane boom and a lifting hook on a standard tower crane complete lifting work by winding and unwinding four ropes, and the four ropes can meet the requirement of objects which are larger than 100 tons and smaller than 10 tons. In the actual use process, the lifting tool is used for lifting small objects of less than 10 tons most of time, particularly one tool is sometimes lifted, the four-rope lifting hook is started, and the effect of killing chickens is achieved. The time for the four-rope lifting hook to receive and release the lifting rope is very long, particularly the lifting operation at the height of more than 100 meters wastes lifting time, and if the lifting rope of the lifting hook is directly changed into two ropes, a heavier object cannot be lifted, so that the problem can be solved by the invention of the tower crane lifting hook with the function of automatically doubling the lifting rope between the two ropes and the four ropes.
Disclosure of Invention
The invention provides a tower crane lifting hook with automatic doubling between two ropes and four ropes, which can realize the automatic doubling between the two ropes and the four ropes of a winch on a crane boom and a lifting rope on the lifting hook, meet different tonnage objects, shorten the lifting time and achieve the purpose of improving the working benefit of the tower crane.
The purpose of the invention is realized by implementing the following technical scheme:
possess two ropes and four automatic tower crane lifting hooks that become doubly between restricting, including jib loading boom, walking dolly and lifting hook, its characterized in that: a travelling trolley component is arranged on the crane boom, a horn-shaped guide rod groove with a large opening at the lower end and a small opening at the upper end is arranged in the center of the travelling trolley component, and fixed pulleys are arranged at the two ends of the guide rod groove; a traction pulley assembly is arranged at the lower end of the walking trolley assembly, a traction pulley is arranged in the center of the traction pulley assembly, a clutch rod is arranged at the top end of the traction pulley assembly, a clutch bolt is arranged at the top end of the clutch rod, a touch switch is arranged at the bottom of the traction pulley assembly, a transmission on/off state connecting line is arranged between the touch switch and the clutch bolt, and a convex base is further arranged at the bottom end of the traction pulley assembly;
the lower end of the lifting hook component is provided with a lifting hook component, two ends of the lifting hook component are provided with movable pulleys, the upper end of the lifting hook component is provided with a concave clamping groove, and the lower end of the lifting hook component is provided with a hook.
