Embodiment 1

[0017] In the figure: 1 is the main girder, 2 is the crane trolley, 3 is the crane trolley, 4 is the track, 5 is the wheel of the crane trolley, 6 is the integrated transmission, 7 is the motor, 8 is the wheel of the crane trolley, 9 10 is an integrated transmission, 12 is the kinetic energy input end of the speed changer 6,10, and 13 is the kinetic energy output end of the speed changer 6,10.

[0018] The use method and scope of this implementation are the same as those of traditional old-fashioned bridge cranes in the past. Below we will focus on describing the ideas related to our innovation:

[0019] The part about main beam 1:

[0020] The original structure: a main girder with a width of 450mm, the track is installed in the axial center of the main girder, and the distance between the track and the upper cover plate of the main girder is 225mm, so a crane trolley is installed on the main girder (crane trolley wheel distance 2500mm, and the widest part of the crane troll...

Embodiment 2

[0031] The main structure and mode of action are the same as in Embodiment 1, except that the distance between the center of the track 4 and the flange on the inner web of the main girder 1 is 170 mm, so that there is still a space of 750 mm between the outer edge of the main girder 1 and the outer edge of the crane trolley 3, It can also be used for people to walk.

Abstract

The invention discloses a bridge crane comprising two girders, and a crane cart and a crane car on both ends; the crane is characterized in that the horizontal widths of the upper cover plates of the girders are 950+ / -2mm, and the web heights of the girders are 1150+ / -2mm; rails are arranged on the upper cover plates of the two girders; the rails are arranged at eccentric positions on the upper cover plates of the girders; and the spacing between the centers of the rails and the upper wing edges of the inner webs of the girders is 110mm to 170mm. The energy-saving and consumption-reducing bridge crane comprises following positive effects, such as, the self horizontal stiffness of the whole crane is improved, the self-weight is reduced by 25 percent, so that steel resources are saved while the safety and lifting capability are ensured. Consequently, the motor power is reduced, and the energy consumption is reduced by 36.5 percent. In addition, the transmission method of the crane abandons an original complicated and heavy transmission system, so that the transmission method is simplified, and the self-weight is further reduced by 25 percent to 30 percent. Similarly, benefiting from the change of the transmission method, the overhaul and the part changing of a crane car transmission system are safer and quicker.

Description

technical field [0001] The invention relates to a hoisting machine, in particular to a novel electric double-girder bridge crane. Background technique [0002] Bridge crane is a special lifting equipment erected across the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge, so it is called bridge crane, commonly known as "traveling crane". The bridge main girder of the bridge crane runs longitudinally on the tracks on the elevated sides on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is a kind of lifting machinery with a wide range of applications and a large number. [0003] Due to historical reasons, the design ideas and structural features of the bridge cranes used in our country are all the technical standards of the former Soviet Union introduced in the 1950s. So far, the desi...
