Track turnout control system for electric block of crane

Abstract

The invention discloses a track turnout control system for an electric block of a crane. The track turnout control system for the electric block of the crane comprises a track turnout, a turnout controller, a turnout actuator and a turnout display, wherein the track turnout comprises a plurality of straight tracks and bent tracks; one ends of the bent tracks and one ends of the straight tracks are combined to form the same track; a track changer is arranged at a combined position; cross sections of the straight tracks and cross sections of the bent tracks are 'U'-shaped and have downward openings; lower edges for supporting pulleys of the electric block are arranged on two sides of each opening; the lower edges are downwards inclined towards the centers of the openings relative to the horizontal plane and the range of the angle of inclination is 1-2 degrees; the turnout actuator and the turnout display are respectively connected with the turnout controller; and the turnout controller controls the track changer in a connection manner. A straight track and bent track combination structure is used in the track turnout control system for the electric block of the crane, space is utilized to a maximum extent, an automatic path correcting function can be fulfilled in a traveling process of a trolley of the electric block in the tracks, and the electric block can always travel in the center of the tracks. The technology of the invention meets market requirements so as to realize a large-span, easily mounted and high-load working process and a low-cost machining process.

Description

technical field [0001] The invention relates to the field of crane equipment, in particular to a crane electric hoist track branch control system. Background technique [0002] In the crane industry, due to the limitation of the space structure, most of the current tracks are welded by splicing processed profiles. Most of the existing tracks use single tracks, and most of the tracks are welded by splicing processed profiles. In this process, the disadvantage is that the processing process is cumbersome, resulting in a waste of processing costs. The most important thing is that in order to enhance its rigidity after splicing, tight support points must be added during the installation process. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a crane electric hoist track branch control system capable of solving the above-mentioned problems. [0004] The technical solution adopted by the present invention in...
