[0024] In order to improve the stability of the left running frame hoisting link, ensure safety production, improve the hoisting operation efficiency of processing, assembly and other processes, optimize the configuration of hoisting lug welding piece 7 on the left running frame welding piece 1, as shown in Figure 2 , Figure 3 As shown in
[0025] As shown in Figure 4 , the hoisting lug welding piece 7 includes hoisting lug bottom plate 8 and hoisting lug 9, the hoisting lug 9 is plate-shaped with hoisting lug hole 91, the lower end surface of the hoisting lug 9 is welded and connected with the upper end surface of the hoisting lug bottom plate 8, the outer edge circle of the lower end surface of the hoisting lug 9 is chamfered to facilitate full welding fusion with the hoisting lug bottom plate 8, and the hoisting lug bottom plate 8 is welded and connected with the side plate of the left running frame welding piece 1; the hoisting lug bottom plate 8 and the hoisting lug 9 are welded to improve the load capacity of the contact between the hoisting lug welding piece 7 and the two sides of the left running frame welding piece 1, especially for the super large excavator left running frame 1, which is very heavy, and the superiority is particularly obvious, which greatly reduces the risk of tearing the two sides of the left running frame welding piece 1, and the effect is completely superior to welding the hoisting lug 9 on the two sides of the left running frame welding piece 1 alone.
[0026] As shown in Figure 5 , the area of the lower end surface of the hoisting lug bottom plate 8 is much larger than the area of the lower end surface of the hoisting lug 9, which is very suitable for the connection and welding of the hoisting lug welding piece 7 and the two sides of the left running frame welding piece 1, so that the welding deformation is small, the welding stress is released, and the two side plates of the left running frame welding piece 1 are very beneficial; the corners of the side of the hoisting lug seat plate 8 are transitioned with chamfered arc, which is suitable for stress release during welding.
[0027] As shown in Figure 6As shown, the hoisting lug hole 91 of the hoisting lug 9 is a large-diameter inner hole, and for the super-large excavator walking frame, the hoisting lug hole 91 adopts a large-diameter inner hole, which is suitable for large hoisting hooks and hoisting ropes; because the left walking frame of the super-large excavator has a heavy lifting weight, in order to facilitate the release of the lifting stress, the outer wall of the upper end of the hoisting lug 9 is a large circular arc 92 concentric with the hoisting lug hole 91, and the lower end of the large circular arc 92 smoothly transitions to the edge of the lower end face of the hoisting lug 9 through an inner small circular arc 93 and an outer small circular arc 94. This arrangement widens the lower end width of the hoisting lug 9 and improves the connection strength.
