7 detailed description of the preferred embodiments

As shown in fig. 1 to 7, a double-beam crane end beam mainly comprises an end beam body 1 and a reinforcing member 2.

End beam body 1 is the rectangle steel pipe, replaces original steel sheet welded structure, has reduced welding work volume. Referring to fig. 1 and 2, two ends of the end beam body 1 are provided with axle holes 3 for mounting wheel axles of wheels. The bottom of the axle hole 3 is provided with an arc-shaped notch 4 for the axle to pass through, and an axle seat flange 5 of the axle is arranged around the axle hole 3 by a plurality of bolts, so that the wheel is arranged on the end beam body 1.

The arc length of the notch 4 ranges from 1/4 to 1/2 of the circumference of the shaft hole 3, so that the shaft seat flange 5 can be conveniently installed in the shaft hole 3 from the notch 4 or taken out of the shaft hole 3.

Referring to fig. 1 and 3, the end beam body 1 is hinged with a reinforcing member 2 near the left and right ends for compensating the strength loss caused by the gap 4 of the axle hole 3. The upper end of the reinforcing piece 2 is hinged on the end beam body 1, and the rotating end of the lower end is in threaded connection with the shaft seat flange 5 and the end beam body 1. Specifically, the reinforcement 2 includes a front wall 6, a rear wall 7, and an end wall 8 welded to the front wall 6 and the rear wall 7, and the front wall 6, the rear wall 7, and the end wall 8 are located inside the end beam body 1.

Referring to fig. 3, the pivot 16 of the reinforcement member 2 is provided with a torsion spring 9 for automatically turning the reinforcement member 2 outward during disassembly, so that the assembly and disassembly work is more convenient and labor-saving. As shown in fig. 3, 4, 6 and 7, the installation structure of the torsion spring 9 is: a compression bar 17 is arranged in the end beam body 1 along the front-back direction, and the torsion spring 9 comprises a first end 10 which is pressed down by the compression bar 17 and a second end 11 which tensions the reinforcing part 2 towards one side of the pivot 16; the inner side of the end wall 8 is provided with a slot 13, the second end 11 of the torsion spring 9 is provided with a bending section 12 which is bent forwards or backwards, and the bending section 12 is embedded into the slot 13.
