In the state where the spacer 33 capable of adjusting the distance, the facing surface 31A is disposed opposite to the standing surface 29A, and the space between both surfaces 29A, 31A is filled with the spacer 33, the standing wall portion 29 and the facing wall portion 31 And two sets of bolts 43 and nuts 44 which are consolidation members. The spacer 33 is composed of a large number of rectangular spacers having different thicknesses, and a spacer having a thickness corresponding to the size of the distance between both surfaces 29A and 31A may be selected from them, or a plurality of spacers may be overlapped. It may be configured. The spacer 33 may be made of any material that does not deform when it receives a thrust due to the extension of the rotating cylinder 14, and can be made of, for example, a synthetic resin or a metal.

  As shown in FIGS. 4 and 5, the attachment member 32 is provided on the opposite side, which is a horizontally long and flat plate-like opposing wall portion 31, and on the opposite side from the opposing surface 31 </ b> A with respect to the opposing wall portion 31.

It is connected. Long holes 35 </ b> A that are long in the extending / contracting direction of the rotating cylinder 14 through which the bolts 34 are inserted are formed in the upper and lower four portions of the mounting portion 35. The mounting surface 15A is a surface parallel to the axis of the pin 37, and intersects with the longitudinal direction of the rotating cylinder 14 whose posture is changed between the maximum extension state and the maximum contraction state. That is, the mounting surface 15A intersects the longitudinal direction of the rotation cylinder 14 in the most extended state, and also intersects the longitudinal direction of the rotation cylinder 14 in the most contracted state.

  As shown in FIGS. 4 and 6, the base member 30 is mounted so as to be opposed to the horizontally long flat plate-like standing wall portion 29 and the mounting surface 15 </ b> A of the gantry 15. A rectangular flat plate-shaped mounting base 39 disposed on the side of 29A, and a rectangular flat that is disposed on the opposite side of the standing surface 29A with respect to the standing wall 29 and extends in a straight line from the mounting base 39 A base main body 41 including a plate-like rib reinforcing portion 40 and a pair of triangular reinforcing ribs 42 and 42 connected to the standing wall portion 29 and the rib reinforcing portion 40 are provided. In addition, screw holes 39a through which the bolts 34 are inserted are formed at four places of the mounting base 39. The base body 41 is fixed to the mounting surface 15A of the gantry 15 by welding. Further, through holes 31a, 31a, 29a, 29a through which the bolts 43 are inserted are formed at both ends in the width direction of the opposing wall portion 31 and both ends in the width direction of the standing wall portion 29, and the opposing wall portion 31 and the standing wall The bolts 43 and 43 are inserted into the through holes 31a and 31a, the through holes (not shown) formed in the spacer 33, and the through holes 29a and 29a in a state where the spacer 33 is disposed between the bolts 43 and 43. The opposing walls 31 and the standing wall 29 are connected and fixed in a state in which the spacer 33 is interposed between the opposing wall 31 and the standing wall 29 by screwing nuts 44, 44 to the front ends of the opposing walls. Further, the four bolts 34 that overlap the attachment portion 35 of the attachment member 32 on the attachment base portion 39 of the base body 41 and penetrate the long hole 35A are screwed into the screw holes 39a formed in the attachment base portion 39. As a result, both (the mounting portion 35 and the mounting base portion 39) are fixed. The standing wall portion 29 (standing surface 29 </ b> A) and the facing wall portion 31 (facing surface 31 </ b> A) are surfaces parallel to the axis of the pin 37 of the rotating cylinder 14.

  Therefore, by selecting one spacer 33 from among a plurality of spacers having different thicknesses between the standing surface 29A and the facing surface 31A, the thickness of the spacer is adjusted and the standing surface 29A and the facing surface 31A are adjusted. The mounting member 32 is fixed to the mounting base portion 39 with four bolts 34 inserted into the elongated holes 35A of the mounting portion 35, thereby making it easy to align the mounting member 32 with the base member 30. It can be carried out. Further, a standing wall portion 29 erected in a direction crossing the longitudinal direction of the rotating cylinder 14 whose posture is changed between the most extended state (see the solid line in FIG. 3) and the most contracted state (see the phantom line in FIG. 3); Since the opposing wall 31 is opposed to each other and is secured by the two bolts 43, the thrust when the rotating cylinder 14 is extended is applied to the both walls 29A, 29A, 31A between both walls 29A, 31A. 31 can be received, and positional deviation of the mounting member 32 can be reliably prevented. The standing wall portion 29 and the opposing wall portion 31 intersect with the longitudinal direction of the rotating cylinder 14 in the most extended state, and also intersect with the longitudinal direction of the rotating cylinder 14 in the most contracted state. Further, the pulling force when the rotating cylinder 14 is contracted is generated by the standing wall portion 29 standing in the direction intersecting the longitudinal direction of the rotating cylinder 14 and the opposing wall portion 31 fixed by the two bolts 43. The mounting member 32 can be reliably prevented from being displaced. Further, since the mounting portion 35 and the mounting base portion 39 are fixed by the four bolts 34, as shown in FIG. 3, when the rotating cylinder 14 changes its posture from the extended state to the contracted state, the rotating cylinder 14 can be reliably prevented from rising (disengaging) from the mounting surface 15A. Further, it is not necessary to adjust the facing distance between the standing surface 29A and the facing surface 31A, that is, when the gap between the standing surface 29A and the facing surface 31A is small, the spacer 33 is not inserted. Can be omitted.

  As shown in FIGS. 7 and 9 (a), 9 (b), and 9 (c), the vertical cylinder portion 23 is provided at the tip end portion of each swing arm 13 with the vertical cylindrical portion 23 extending downward. The hydraulic jack cylinder 24 is provided in the inside of the hydraulic cylinder for moving the ground 25 supporting the work vehicle up and down. 9A shows a state in which only the plate 45 is mounted in the vertical cylinder portion 23, FIG. 9B shows a tip portion of the right swing arm 13, and FIG. The tip part of the swing arm 13 for the left is shown. And it has the square-shaped plate 45 in which the circular cylinder through-hole 45A in which the fluid pressure jack cylinder 24 is fitted is formed. The plate 45 is formed with a pair of pipe insertion holes 45 a and 45 b for passing a pipe 46 for supplying a fluid to the fluid pressure jack cylinder 24. These pipe insertion holes 45a and 45b are formed obliquely from the cylinder through hole 45A to two corner portions located on the base end side of the swing arm 13, respectively, and face each other with a predetermined distance in the width direction Is located. The supply of oil to the fluid pressure jack cylinder 24 is performed by using the inner side plates of the swing arms 13 (the left swing arm 13 is the right side plate 21 (see FIG. 9C)) and the right swing arm 13 is the left side plate 20. (Refer to Fig. 9 (b)) is carried out through two pipes 47, 48. The two pipes 47, 48 guided to the tip of the swing arm 13 are guided downward, It is connected to a valve 49 in the side plate 21 or 20 through an opening 21K (see FIG. 7) formed in the side plate 21 or 20. The valve 49 is attached to the upper end of the fluid pressure jack cylinder 24. Although not described, the front outriggers 6 and 7 can be implemented with these configurations.

  Therefore, by inserting the fluid pressure jack cylinder 24 into the cylinder through hole 45A of the plate 45 closing the opening 23K of the vertical cylindrical portion 23, the fluid pressure jack cylinder 24 rolls in the tip of the swing arm 13 at the time of expansion and contraction operation Can be prevented. A pipe 46 for supplying fluid to the fluid pressure jack cylinder 24 is a pipe insertion hole located inside the pair of holes (the left swing arm 13 has a right pipe insertion hole 45a (see FIG. 9C). ) By passing the right swing arm 13 through the left pipe insertion hole 45b (see FIG. 9B)), it is more likely to be scattered during traveling or work than when passing through the outer hole. It is easy to avoid damage to the piping. At this time, the inner side of the left swing arm 13 and the right swing arm 13 are opposite in right and left, so for example, the left side plate and the right side have holes for piping corresponding to the inner side of the left swing arm 13. When the right side plate having the corresponding piping hole is provided on the inner side of the swing arm 13, it is necessary to reassemble again when the right and left plates are incorrectly assembled to the swing arm 13. As in the case of the plate 45 having the pair of pipe insertion holes 45a and 45b, only by assembling the plate 45 to the swing arm 13 so that the pair of pipe insertion holes 45a and 45b are positioned on the base end side of the swing arm 13. Thus, it is possible to avoid an assembly error on the swing arm 13. Therefore, it is only necessary to select one of the pipe insertion holes 45a or 45b located inside and pass the pipe 46 through the selected pipe insertion hole 45a or 45b. Further, since the plate 45 can be shared, it is advantageous in terms of cost.

  Further, as shown in FIGS. 7 and 8, two pairs of protrusions 50 and 50 are provided at both ends in the width direction of the upper surface of each swing arm 13, and the four protrusions 50 have a width direction (lateral direction). A through hole 50A penetrating therethrough is formed. Specifically, two sets of a pair of protrusions 50 and 50 that are opposed to each other in the width direction are provided on the base end side portions of the left and right side plates 20 and 21 that constitute the swing arm 13 in the longitudinal direction. The distance between the two pairs of protrusions 50, 50, 50, 50 provided in the longitudinal direction is not limited to the distance shown in the drawing, and the positions of the protrusions 50, 50, 50, 50 provided in the longitudinal direction are also determined by the swing arm 13. It may be in any position in the longitudinal direction. In this way, a tool box (not shown) is passed through the ropes and wires through the through holes 50A, 50A, 50A, 50A of the two sets of protrusions 50, 50, 50, 50 standing on both ends in the width direction of the upper surface of the swing arm 13. Is fixed to the swing arm 13 or a pipe (hose) is fixed to the swing arm 13 or the like. Although not described, the front outriggers 6 and 7 can be implemented with these configurations.
