Embodiment 1

[0015] Example 1, using the electric single-girder crane curved track operation technology to solve the problem of dispatching and transporting two sluices sharing a set of maintenance gates

[0016]The two sluices at the "T"-shaped intersection of the river share a set of maintenance gates and lifting devices for gate maintenance to meet the lifting requirements of the maintenance gates. The lifting device model is LDA type 5-ton electric single-girder crane with a span of 8.5 meters and a lifting height of 18 meters. The design weight of a single maintenance gate is 2.6 tons. 26 meters. The inner arc radius of the arc section at the 90° intersection of the two gate tracks is R7500 mm, and the outer arc and inner arc have the same center. The end beam wheel running mechanism of the original electric single-girder crane has been changed. The running mechanism adopts double-sided drive and is composed of steering wheels, single-speed drive motors, double-speed drive motors, co...

Abstract

The present invention provides technology for electric single-beam crane to move in curved tracks. In the T-shaped joining part of rivers, two nearby water gates are provided with one shared electric single-beam crane, which can move in straight line and curved line. The two water gates and two crane rooms have central line angle of 90 deg, and two sections of crane running track in 90 deg angle have one circular transition section in between. The electric single-beam crane running mechanism consists of main beam, end beams, turnable wheels, single speed driving motor, double speed driving motor, and contact sensing signal controller. The end beams and the turnable wheels are driven on two sides, the outer side is driven with the single speed driving motor, and the inner side is driven with the double speed driving motor. The contact sensing signal controller consists of contact in the inner side end beam and sliding sheet in the circular inner side track.

Description

technical field [0001] The invention relates to a crane, in particular to a curved track operation technology of an electric single-girder crane. Background technique [0002] For inspection and maintenance of existing river sluices, each sluice needs to be equipped with maintenance gates and lifting devices. Even if the two rivers are located at two sluices that are very close to each other at the "T"-shaped intersection, generally a set of maintenance gates and lifting devices are required to be configured respectively. This maintenance configuration situation not only has a large amount of equipment installation work, troublesome maintenance of the maintenance equipment, but also causes a waste of funds and manpower. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the large amount of equipment installation work caused by the large amount of installation work for ...
