Symmetrical deflection type double-bridge crane

Abstract

The invention discloses a symmetrical deflection type double-bridge crane. The symmetrical deflection type double-bridge crane comprises a supporting frame, a traveling mechanism, a longitudinal moving frame, two transverse deflection beams and a plurality of storage boxes. The supporting frame serves as a bracket of the whole crane; the traveling mechanism is used for driving the supporting frameto travel on the ground; the longitudinal moving frame is a quadrilateral frame, the quadrilateral frame is mounted on the supporting frame through lifting devices, the two transverse deflection beams are mounted on the quadrilateral frame through a longitudinal horizontal-moving device, and the longitudinal horizontal-moving device drives the transverse deflection beams to move in the longitudinal direction of the quadrilateral frame; and the storage boxes are used for rising and falling along with the lifting devices to hook box bodies serving as cargos and mounted on the two transverse deflection beams through transverse horizontal-moving devices, and through the lifting devices, the transverse horizontal-moving devices and the longitudinal horizontal-moving device, the storage boxes can move in the space area where the supporting frame is located so as to complete hoisting of the cargos. The symmetrical deflection type double-bridge crane is simple in structure, a plurality of targets can be hoisted and placed through the single stroke, and the carrying efficiency is high.

Description

technical field [0001] The invention belongs to the field of cranes, and relates to a displacement crane, in particular to a symmetrical displacement double-bridge crane, which is a double-girder bridge crane with two bridge frames and large and small car mechanisms. Background technique [0002] As my country's economic development changes from extensive growth to intensive growth, the development model of port machinery is also changing. Port loading and unloading equipment is changing from the past large-scale, high-speed, and automated to specialized, intelligent, energy-saving and environmentally friendly, and drives new technological progress. Due to the limited area of ​​the port site, it is particularly important to make efficient use of the port area. At present, traditional bridge cranes can only arrange one set of hoisting mechanisms in a single working area, with low space utilization and a single path. Therefore, people pay more and more attention to the resea...

AI Technical Summary

Problems solved by technology

Compared with most of the existing domestic and foreign studies, it is found that there are the following problems: complex structure, low space utilization rate; single-stroke action can complete the lifting action of the target object once at most, and the handling efficiency is low

However, it uses flexible legs, which requires high manufacturing and installation precision and is expensive
