A New Type Electric Semi-gantry Crane

Abstract

A new type electric semi-gantry crane, which relates to the field of cranes, including an upper beam, an upper beam operating mechanism, a main beam, an electric hoist, outriggers, a lower beam operating mechanism, a lower beam, the active wheel set of the upper beam operating mechanism and The driven wheel set is suspended on the I-beam or H-shaped steel flange surface, the lower part of the driving wheel set and the driven wheel set are connected with the upper beam, and the upper beam is hinged with one end of the main beam. After the main beam and the upper beam are connected, The other end is connected with the upper end of the outrigger, the main beam is suspended between the outrigger and the upper beam, the electric hoist is suspended on the main beam, the lower end of the outrigger is connected with the lower beam, and the two ends of the lower beam are respectively installed There are driving wheel sets and driven wheel sets. The beneficial effect is that all running mechanisms use stop wheels instead of wheel stops, which improves positioning accuracy, reduces energy consumption and noise, especially the use of suspended beams, which effectively improves the stability of the frame and simplifies the steel column structure of the workshop , reduces the investment of the factory building, and at the same time, because the main beam extends under the driving beam, the effective stroke of the semi-gantry crane is increased by more than 1 meter.

Description

technical field [0001] The invention relates to the field of cranes, in particular to an electric semi-gantry crane. Background technique [0002] Electric semi-gantry cranes are the product of the development of modern industrial production. With the development of industrial production, many factories gradually adopt assembly line production with the increase of industrial product output. Semi-gantry hoisting, so as to achieve energy saving, time saving, timely and convenient, and meet the characteristics of small investment. However, the upper beam and running mechanism of this electric semi-gantry crane are set on the guide rail of the driving beam above the corbel of the half-gantry crane under the corbel of the bridge crane. The effective stroke of the main girder of the half-gantry crane is short, especially the bridge type The large area next to the crane column cannot be fully utilized. Usually, the hook of the electric hoist is more than 1.6m from the center of th...

However, the upper beam and running mechanism of this electric semi-gantry crane are set on the guide rail of the driving beam above the corbel of the half-gantry crane under the corbel of the bridge crane. The effective stroke of the main girder of the half-gantry crane is short, especially the bridge type The large area next to the crane column cannot be fully utilized. Usually, the hook of the electric hoist is more than 1.6m from the center of the edge column, which wastes a lot of space. See figure 1 shown
