Hanger and lifting device using hanger

Abstract

The invention relates to a hanger and a lifting device using the hanger, the lifting device comprises the hanger and a trolley frame, the trolley frame is provided with a lifting mechanism and a walking mechanism, the hanger comprises a fixing frame, a middle frame and a bottom frame which are sequentially arranged along the up and down direction, the fixing frame is fixedly arranged on the trolley frame, the bottom frame is connected to the lifting mechanism, the bottom frame is also provided with a connecting structure for connection with a heavy object to be lifted, a left up connection rod and a right up connection rod are arranged between the middle frame and the fixing frame, the left up connection rod and right up connection rod are parallel to each other in a left-and-right mode and are parallelly arranged, a left down connection rod and a right down connection rod are arranged between the middle frame and the bottom frame, the left down connection rod and the right down connection rod are parallel to each other in the left-and-right mode and are parallelly arranged, one of the left up connection rod and the left down connection rod tilts forward, the other one of the left up connection rod and the left down connection rod tilts backward, the middle frame, the fixing frame, the left up connection rod and the right up connection rod form a first parallelogram linkage mechanism; and the middle frame, the bottom frame, the left down connection rod and the right down connection rod form a second parallelogram linkage mechanism. The hanger solves the problem that due to the inertia effects in starting and stopping of a hanger in the prior art, swing of the heavy object to be lifted may be caused.

Description

technical field [0001] The invention relates to a sling in the lifting field and a lifting device using the sling. Background technique [0002] Existing hoisting equipment includes a double-girder crane, and the double-girder crane includes a trolley frame provided with a hoisting mechanism and a traveling mechanism. The hoisting mechanism includes a steel wire rope and a suspension hook connected to the wire rope. In actual use, the trolley frame is guided and moved along the front and rear directions by the traveling mechanism and assembled on the corresponding track. The heavy object to be lifted is hoisted on the hook by a simple sling, and the heavy object to be lifted is realized by walking along the track by the traveling mechanism. lifting. The existing problem of this kind of lifting equipment is that the heavy objects to be lifted, such as stacking items, have high requirements on the stability of the lifting process, and the spreaders of the existing lifting equ...
