As shown in fig. 1, a hydraulic steel pipe fixing structure of an excavator comprises a fixing seat 2, a pressing plate 5 and a fastening piece 4; a transition plate 6 is arranged between the fixed seat 2 and the structural member main body 1; the bottom surface of the transition plate 6 is fixed with the structural member main body 1, and the bottom surface of the fixed seat 2 is fixed with the top surface of the transition plate 6; the hydraulic steel pipe 3 is assembled between the pressing block 5 and the fixed seat 2, and the pressing block 5 and the fixed seat 2 are connected together through the fastening piece 4.
With continued reference to fig. 1, the transition plate 6 is welded to the structural body 1, and the anchor block 2 is welded to the transition plate 6.
Further scheme: the contact area of the transition plate 6 with the structural member body 1 is larger than the contact area of the fixing seat 2 with the transition plate 6, so that the weld between the structural member body 1 and the transition plate 6 is larger than the weld between the transition plate 6 and the fixing seat 2.
With continued reference to fig. 1, the semicircular notch in the upper portion of the transition plate 6 and the semicircular notch in the lower portion of the pressing block 5 constitute a circular notch in which the hydraulic steel pipe 3 is fitted.
Further scheme: the diameter size of the circular gap is larger than the outer diameter size of the hydraulic steel pipe 3.
The preferable scheme is as follows: the diameter size of the circular gap is 1 mm-2 mm larger than the outer diameter size of the hydraulic steel pipe 3.
Further scheme: the fastener 4 is a bolt; two threaded holes are respectively formed in two sides of the fixing seat 2, two unthreaded holes concentric with the threaded holes are formed in the pressing plate 5, and the pressing plate 5 and the fixing seat 2 are connected together by the aid of the two bolts penetrating through the two unthreaded holes in the pressing plate 5 and screwed into the two threaded holes in the fixing seat 2.
