Abstract

The invention relates to the technical field of electromechanical equipment, and discloses electric hoist hoisting equipment capable of achieving ordered winding and reduction of a swing amplitude. The equipment comprises a frame body, the top of the frame body is rotatably connected with a winding mechanism, the left end and the right end of the frame body are slidably connected with lifting mechanisms, the bottom of the frame body is slidably connected with an adjusting mechanism, a fixing frame is fixedly connected to the middle of the frame body, and a steel rope is wound in the frame body. According to the electric hoist hoisting equipment capable of achieving ordered winding and reduction of the swing amplitude, when the swing amplitude of a steel rope is too large, the steel rope swings to abut against a guide roller and is matched with a first connecting rod for transmission, so that a rubber rod rotates to abut against a contact point, a second motor drives a screw to rotate, a sliding frame drives a movable frame to ascend, the swing radius of the steel rope is increased; and when a first motor is started for rotation, a first rotating shaft drives a groove disc to rotate, based on limiting of a limiting ring groove, the guide roller gradually conducts feeding from left to right, and the effect of synchronous feeding and ordered winding is achieved.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to an electric hoist hoisting equipment for orderly winding and reducing swing amplitude. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places. Compact, but due to the long length of the hoisting steel rope, the suspended heavy objects will swing back and forth due to inertia during operation. When the swing range is large, the suspended heavy objects are easy to be thrown out, and the heavy swing range is too large to lower the equipment The stability of the internal structure connection increases the risk during the hoisting process and reduces the safety of the equipment. When the electric hoi...
