[0002] At present, there are many types of cranes in China, especially in the metallurgical and iron and steel industries. The end girders of double-girder bridge cranes that are widely used are four-wheel structure small end girders and connecting beams. The failure rate of this structure is frequent after a period of use. , especially the deformation of the end beam connection, the deformation fault of the small end beam structure, and the occurrence of rail gnawing, derailment, and abnormal wear of the large running wheel after the fault, and the installation groove of the bearing seat in the current structure is a square structure, and the bearing seat is As a whole, this is obviously unfavorable for the maintenance of the running wheel structure, and these are all that those skilled in the art do not expect to see

The present invention relates to the technical field of lifting equipment, and in particular to an end beam device of a double-girder bridge crane. By setting the end beam, the end beam includes a first end beam body and a second end beam body connected between two first end beam bodies, and Both the first end beam body and the second end beam body are box-shaped beams, both ends of the second end beam body are connected with the connecting ends of the first end beam body in complementary fit, and the first end beam body and the second end beam body The joints of the beams are covered with connecting plates all around to fix the first end beam body and the second end beam body together through the connecting plates, so that the end beam structure is more stable and reliable, and the failure frequency of the running wheel is greatly reduced ; In addition, the device is also provided with a semicircular support mounting groove under the running wheel end of the first end beam body, and the semicircular bearing support of the bearing seat is fixed on the support mounting groove, and the The other semicircular bearing support of the bearing seat is detachably connected to the semicircular bearing support, thereby improving the maintenance efficiency of the running wheel structure on site.
