Multi-hoisting point two-dimensional transmission automatic rope arranging compound crane

Abstract

The invention relates to a multi-hoisting point two-dimensional transmission automatic rope arranging compound crane which comprises a base, a frame, a reducing brake motor and a rope arranging roller. The output shaft of the reducing brake motor drives the rope arranging roller to rotate; the crane is characterized in that two ends of the rope arranging roller are rotationally installed between two supporting wallboards; lower parts of the supporting wallboards are glidingly installed on sliding bars symmetrically installed at two ends of the upper part of the frame; a movable base plate is longitudinally and fixedly installed at one end of the frame; a horizontal screw penetrating through the inner part of the roller is fixedly installed on the movable base plate; the horizontal screw is matched with a nut installed at the axle center of the end part of the rope arranging roller; and a deflecting pulley group is installed on the frame at the lower part of the rope arranging roller. The crane integrates a boom machine and the deflecting pulley group into a whole, a motor drives a winding drum to drive a hoisting cable to lift weights, meanwhile, the horizontal movement of the winding drum is realized, and two-dimensional transmission mode is realized, so that automatic rope arranging function is realized during small-space and multi-angle installation, and meanwhile, the crane has the advantages of low cost, easiness in installation and high safety.

Description

technical field [0001] The invention belongs to the field of stage machinery, in particular to a multi-suspension two-dimensional transmission self-draining rope composite crane. Background technique [0002] The stage boom machine is a necessary equipment for theaters, conference centers, studios, concert halls and other performance places, and it is the carrier of stage lighting, scenery props and stage curtains. The existing boom machine is mainly composed of a deceleration brake motor and a drum. The multi-hanging point steel wire rope is wound on the drum. The multi-hanging point steel wire rope is connected to the boom of the stage curtain or other lifting stage equipment through the turning pulley above the crane. At present, during the operation of the boom machine, the drum only rotates and does not perform horizontal displacement, which is prone to superposition of steel wire ropes and affects the wire rope arrangement on the drum. The reel of existing crane is to...

Problems solved by technology

In fact, many existing theaters cannot meet the installation height requirements and cannot install stage booms. Therefore, it is urgent to develop a device that can automatically arrange the ropes to realize the function of stage booms under the condition of insufficient space.
