Below, illustrate by improving a kind of piping erection structure that being provided with of this sweep constituted with Fig. 6,7.Fig. 6 is the lateral view of the hydraulic piping structure of expression apparatus for work, and Fig. 7 is the vertical view of Fig. 6.
Upper rotating body 12, between the spirogyrate bearing 35 and concave shaped bearing 36 be located to the rotary body leading section that supports described Work machine rocking bracket 16, the hydraulic hose that has towards the inner space of rocking bracket 16 38 openings stretches out hole 61, simultaneously, stretch out the behind in hole 61 at this hydraulic hose, have the crooked piping erection space 62 of laying of the hydraulic hose that is used for upper rotating body inside.In the piping erection space 62 of this upper rotating body inside, have pipeline geometrical clamp parts 67 and pipeline guiding part 68, these pipeline geometrical clamp parts 67, be used to tie up respectively two of fixed hydraulic flexible pipes 40,43,44,45, these hydraulic hoses link to each other with control transfer valve 66 with oil cylinder control transfer valve 65, auxiliary activities utensil oil cylinder with control transfer valve 64, scraper bowl with control transfer valve 63, rocking arm oil cylinder with the cantilever tank of the inside 60 of being located at upper rotating body 12 respectively; This pipeline guiding part 68, what be positioned at described hydraulic hose stretches out 61 places, hole, is used to make each hydraulic hose 40,43,44,45 to penetrate the inner space 38 of described rocking bracket 16.Therefore, described each hydraulic hose 40,43,44,45 is laid between described pipeline geometrical clamp parts 67 and the described pipeline guiding part 68 agley, and passes through the inner space 38 of described rocking bracket 16.
Fig. 8 is the front view of expression pipeline guiding part, and Fig. 9 is the front view of expression pipeline geometrical clamp parts.
As shown in Figure 8, described pipeline guiding part 68, have can a line 2 insertion sections 70,71 up and down of inserting hydraulic hose, ground, in the present embodiment, be divided into two insertion sections 70,71 up and down by the tubing of horizontal direction.In addition, as shown in Figure 9, have a plurality of hydraulic hose patchholes that are the distribution of 2 files on the rubber buffer 72 of described pipeline geometrical clamp parts 67, and the peripheral part of this cushion pad is fixing by tying up clamping part 73.
Therefore, the flexible pipe of described bending is laid in the following manner: crooked distolateral pipeline geometrical clamp parts 67 by described 2 files at curved spout position grip with the interval of regulation along the vertical direction, simultaneously, in crooked distolateral two insertion sections 70,71 that a line respectively arranged up and down by being scattered in of described pipeline guiding part 68 of another of curved spout position.Therefore, when being configured in the piping erection space with this vacant state, each crooked flexible pipe position can not overlap.
Described pipeline geometrical clamp parts 67 and pipeline guiding part 68, owing to be to bring in the case of bending that keeps flexible pipe, therefore can suppress bending springback ground, the curved spout position is remained in the piping erection space 62 with the state that is bent at two of described each hydraulic hose crooked position.Therefore, when swing along with rocking bracket 16, when described each hydraulic hose is subjected to tractive or pushing, 68 channeling conducts of pipeline guiding part, to suppress described each hydraulic hose causes crooked radius of curvature along radial direction displacement (lateral shift) variation, described each hydraulic hose is moved along axis direction, increase or reduce the deflection at curved spout position.Thereby absorb the displacement that causes hydraulic hose because of the swing of rocking bracket 16.
In addition, described pipeline geometrical clamp parts 67 are placed on the aerial bearing 69 within the piping erection space 62 of being located at described upper rotating body inside built on stiltsly, make between and described pipeline guiding part 68 between the curved spout position be in vacant state.Therefore, although hydraulic hose moves because of the curved spout displacement, can not touch the last lower wall surface of upper rotating body internal pipeline installing space 62 yet.
In addition, in described each hydraulic hose, have only cantilever tank with hydraulic hose 40 by the upper/lower positions place of clamping at 2 file clamping parts of described pipeline geometrical clamp parts 67, and insert in the following insertion section 71 of described pipeline guiding part 68, these are different with the laying of each oil cylinder usefulness hydraulic hose in rocking arm, scraper bowl, the auxiliary activities utensil.Therefore, cantilever tank is used the also different of hydraulic hose 43,44,45 with the laying path that hydraulic hose 40 passes through with other each oil cylinder except that cantilever tank, like this, even when its displacement is big in swing, can not enwind other each oil cylinder hydraulic hose yet.
In addition, constitute as described above, fixedly in rocking arm, scraper bowl, the auxiliary activities utensil each oil cylinder with the geometrical clamp of hydraulic hose and cantilever mounted oil cylinder geometrical clamp with hydraulic hose, lay respectively at by the diverse location place of oscillation center along radial direction, therefore, along with the swing of rocking bracket, the shift motion of hydraulic hose produces difference, causes cantilever tank to use the different of hydraulic hose 43,44,45 with each oil cylinder in mobile and rocking arm, scraper bowl, the auxiliary activities utensil of hydraulic hose 40.Yet, even this different moving arranged, but because cantilever tank is inserted into the following insertion section 71 of described pipeline guiding part 68 with hydraulic hose 40, and be fixed on upper/lower positions place in the piping erection space 62 by pipeline geometrical clamp parts 67, arranged apart with other each oil cylinder with hydraulic hose 43,44,45, therefore, cantilever tank with each oil cylinder of hydraulic hose 40 and rocking arm, scraper bowl, auxiliary activities utensil with not producing friction between the hydraulic hose 43,44,45.
In addition, as shown in Figure 9, described pipeline geometrical clamp parts 67 can be positioned on the aerial bearing 69 for the center by axis of rotation 75 with freely swinging, this axis of rotation have be located at described pipeline geometrical clamp parts 67 bottoms roughly be upper and lower to the axle center.Like this, along with the carriage swing, and putting under the tractive deflection at curved spout position, the effect of pushing deflection counter-force, pipeline geometrical clamp parts 67 swing, therefore, be easy to make each flexible pipe at curved spout position to remain on this case of bending and swing, snarl each other not between flexible pipe with whole flexible pipes.
As mentioned above, inside in upper rotating body, dispose cantilever by hypomere successively overlappingly to epimere; rocking arm; scraper bowl; the auxiliary activities utensil respectively control transfer valve 63; 64; 65; 66; from this overlapping; the described transfer valve 63 of respectively controlling of arranged in order; 64; 65; 66 each 2 hydraulic hose 40 that comes out; 43; 44; 45; 2 files by described pipeline geometrical clamp parts 67 are tied up clamping part 73, clamp cantilever successively according to hypomere to epimere; rocking arm; scraper bowl from this clamping part; each oil cylinder of auxiliary activities utensil with the fixed order of hydraulic hose within piping erection space 62.And then each oil cylinder of rocking arm, scraper bowl, auxiliary activities utensil deflected into bending with hydraulic hose 43,44,45, and laterally insert abreast in the last insertion section 70 of described pipeline guiding part 68 by the tab order that described 2 files are tied up clamping part 73, simultaneously, cantilever tank is deflected into bending with hydraulic hose 40, laterally insert abreast in the following insertion section 71 of described pipeline guiding part 68, so that penetrate the inner space 38 of described rocking bracket 16.
Then; each oil cylinder is with hydraulic hose 43,44,45 in rocking arm, scraper bowl, the auxiliary activities utensil; lay path 46, be fixed and be positioned near the cantilever installation shaft 17a of cantilever installation portion 33, by the 2nd pipelines in the described rocking bracket 16 then respectively with rocking arm oil cylinder 21, bucket cylinder 22, and other operating apparatus oil cylinder (not shown) be connected.In addition, cantilever tank is with hydraulic hose 40, lays to be fixed behind the path 42 and to be positioned by the 1st pipelines in the rocking bracket 16 to be connected with cantilever tank 20 near the connecting pin 32 of cantilever tank installation portion 32.
More than the present invention of Gou Chenging has following effect.
Compared with prior art, has the effect that can shorten hose length, this be since with the cantilever tank of rocking bracket with the mounting arrangements of hydraulic hose, with the different paths of other oil cylinder with hydraulic hose, by being located at the laying path in the rocking bracket and after near the cantilever tank connecting pin, directly linking on the cantilever tank.In addition because the cantilever tank hydraulic hose is fixed near the cantilever tank connecting pin by geometrical clamp, so can reduce this flexible pipe with cantilever tank swing up and down and the deflection of deflection can also prevent because of contacting the damage that produces with the outer barrie thing.
And, with hydraulic hose agley mounting arrangements to rocking bracket, be to keep this case of bending by pipeline geometrical clamp parts that are located at both ends, hose bending position and pipeline guiding part, therefore can suppress crooked resilience, simultaneously, can also in the piping erection space, keep the curved spout position with the state that is bent.
In addition, when the swing of rocking bracket makes described each hydraulic hose be subjected to tractive, pushing and is mobile, the effect of pipeline guiding part is: can guide described each hydraulic hose, so that they move towards the roughly axis direction of flexible pipe, can also increase and decrease the deflection at curved spout position, absorb the displacement that hydraulic hose produces because of the rocking bracket swing.Therefore, the piping erection space of described upper rotating body inside only needs to hold the space of increase and decrease scope of the deflection at curved spout position, compared with prior art, can dwindle the pipe arrangement space.
In addition, pipeline geometrical clamp rack for assembly unit vacant lot is arranged in the piping erection space of upper rotating body inside, make the curved spout position arrange with suspension status, therefore, even hydraulic hose moves because of the displacement of crooked position, hydraulic hose also can not touch the last lower wall surface in the piping erection space of upper rotating body inside, thus can prevent owing to this on the flexible pipe damage that causes of lower wall surface friction.
The curved spout position that hangs is connected across tying up on clamping part and the 1 line pipeline guiding part of 2 files, and each curved spout position can not overlap, and can make flexible pipe not have resistance like this when carrying out displacement with case of bending, can also prevent snarl.
Because each oil cylinder of rocking arm, scraper bowl, auxiliary activities utensil is laid up and down with hydraulic hose dividually with hydraulic hose and cantilever tank, therefore, even the amount of movement of two flexible pipes creates a difference because of the swing of rocking bracket, can not contact between the two yet, damage can avoid friction.
In addition, when the crooked position at hydraulic hose applies flexural force, under the effect of this flexible pipe counter-force, pipeline geometrical clamp parts are to swing about the center with the axis of vertical direction, therefore, the case of bending of hydraulic hose can be kept at an easy rate, snarl each other can also be prevented between hydraulic hose.
In addition, each hydraulic hose that is arrived each oil cylinder by each control transfer valve can not reported to the leadship after accomplishing a task halfway yet, can fitly be arranged by pipeline geometrical clamp parts and pipeline guiding part.
