Automatic centering system for crane hanging over rail

Abstract

The invention discloses an automatic centering system for a crane hanging over rail. The automatic centering system comprises a main vehicle rail and an auxiliary vehicle rail, wherein a first supportis vertically arranged on the side wall of the upper side of the main vehicle rail, and a first driving motor is arranged on the side wall of one side of the first support; a second support is vertically arranged on the side wall of the upper side of the auxiliary vehicle rail, and a second driving motor is arranged on the side wall of one side of the second support; mutually matched centering systems are arranged on the side wall of the main vehicle rail and the side wall of the auxiliary vehicle rail; each centering system comprises two controllers, an infrared emitter and an infrared receiver; a groove is formed in the side wall of one side of the main vehicle rail, an opening of the groove faces the auxiliary vehicle rail, and each infrared emitter is arranged inside the correspondinggroove in an inserting manner. The automatic centering system is simple in structure and convenient in operation, the crane hanging over rail is compact and smart in structural design, the centeringoperation is convenient and accurate, time-saving and labor-saving, and the fastening firmness of the rail after centering is stable. Therefore, the problem that electric hoists are difficult to move,caused by rail shaking, cannot appear.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an automatic centering system for a crane over rail. Background technique [0002] Crane over-rail cranes are mostly used in thermal power plants, nuclear power plants, aircraft manufacturers and manufacturers that need two cranes to automatically dock. Enter another track and work back and forth freely. The trolley or electric hoist placed on the track will lift the equipment from one track to another track to complete the lifting of the equipment. At present, the docking of the main car track and the auxiliary car track is mostly realized by manual operation, and the operation is cumbersome; in addition, the main car track and the auxiliary car track are fixedly connected by a fixing device, but there is a gap in the connection, which is not stable enough. Electric hoist The whole device vibrates when working. For this reason, we propose an automatic centering system for crane...
