The specific embodiment
Below, preferred embodiment of the present invention with reference to description of drawings.The formation of tubine machine 100 at first, is described with reference to Fig. 1 and Fig. 2.Fig. 1 is the stereogram of the tubine machine 100 of an embodiment of the present invention, under a part of cut state of Lift Part 3 and upper frame element 8, it is illustrated.Fig. 2 (a) is the amplification view of tubine machine 100 of a part in cross section that amplifies the IIa-IIa line of presentation graphs 1, and Fig. 2 (b) is the sectional view of thrust jack 7.
Shown in Fig. 1 and Fig. 2 (a), sleeve pipe 1 is pushed earthward and is rotated the parts that excavate this ground to lower frame element 5 side shiftings through Lift Part 3 on one side by the revolving force rotation from hydraulic motor 21 on one side.Sleeve pipe 1 forms cylindric, and the axis direction of rotary middle spindle S (direction of principal axis of sleeve pipe) sets to perpendicular to ground.
Shown in Fig. 2 (a), Lift Part 3 is the flexible parts that move and connect to sleeve pipe 1 via main clamping part 4 to above-below direction (Fig. 2 (a) above-below direction) by thrust jack 7.
Thereby secondary clamping part 6 is when main clamping part 4 does not grip sleeve pipe 1, to grip the parts that sleeve pipe 1 prevents that sleeve pipe 1 from falling.As shown in Figure 1, secondary clamping part 6 has tape member 61, hydraulic cylinder device 62.In addition, for the detailed formation of secondary clamping part 6, then state with reference to Fig. 5.
Shown in Fig. 2 (b), thrust jack 7 be through make total length flexible make Lift Part 3 with respect to lower frame element 5 to the parts that above-below direction moves, have: thrust jack urceolus 71, thrust jack inner core 72, thrust hydraulic cylinder 73.
In addition; Level jack 10 is provided in the vertical direction below of thrust hydraulic cylinder 73; Thereby make from thrust hydraulic cylinder 73 consistent with level jack 10 via the supporting-point of lower frame element 5 these loads of supporting to the load point of lower frame element 5 transfer charges; Therefore, on lower frame element 5, do not produce because the moment of deflection that the contractility of thrust hydraulic cylinder 73 causes.In addition, can reduce the area that is provided with of tubine machine 100 (with reference to Fig. 1).
For example; When level jack 10 is set with thrust hydraulic cylinder 73 positions differently; Different corresponding with thrust hydraulic cylinder 73 positions with level jack 10, the lower frame element 5 that connects level jack 10 and thrust hydraulic cylinder 73 and load point and supporting-point are inconsistent to cause producing moment of deflection owing to hydraulic cylinder power is input to from thrust hydraulic cylinder 73.In addition, when level jack 10 is provided in the outside (the direction outside, footpath of sleeve pipe 1 etc.) of thrust jack inner core 72, the floor space of tubine machine 100 is increased.Therefore, aspect being provided with of tubine machine 100, produce restriction (setting in narrow and small place become difficulty).
Relative therewith; In this embodiment; Level jack 10 is set at the vertical direction below of thrust hydraulic cylinder 73; Make from thrust hydraulic cylinder 73 consistently with level jack 10, therefore, on lower frame element 5, can not produce moment of deflection via the supporting-point of lower frame element 5 these loads of supporting to the load point of lower frame element 5 transfer charges.Thus, the intensity of lower frame element 5 needn't consider because the influence of the moment of deflection that the contractility of thrust hydraulic cylinder 73 causes can make the miniaturization of lower frame element 5 miniaturizations and realization tubine machine 100.In addition, the situation that is provided in the outside of thrust jack inner core 72 with level jack 10 is compared, because level jack 10 is provided in the vertical direction below of thrust hydraulic cylinder 73, so can reduce the floor space of tubine machine 100.Thus, reduce correspondingly, make the possibility that is set in narrow and small place, can increase the degree of freedom of the setting of tubine machine 100 with floor space.
A plurality of clamping hydraulic cylinders 9 are hydraulic cylinders that total length and the oily quantity delivered of action are changed accordingly, and the end of downside is connected with Lift Part 3, and the end of upside is connected with upper frame element 8.At this,, then make upper frame element 8 approaching to Lift Part 3 if the total length of clamping hydraulic cylinder 9 is shortened.Its result makes clamping part 42 move to the outer peripheral face 1a of sleeve pipe 1 side (Fig. 2 (a) right side) along the inner peripheral surface 41a of cone part 41.Thus, push the outer peripheral face 1a of sleeve pipe 1, make sleeve pipe 1 connect to cone part 41 via clamping part 42 by clamping part 42.On the other hand, if the elongation of the total length of clamping hydraulic cylinder 9 then makes upper frame element 8 separate from Lift Part 3.Its result makes clamping part 42 separate from the outer peripheral face 1a of sleeve pipe 1, and is disengaged with respect to the connection of the sleeve pipe 1 of cone part 41.
The detailed formation of cone part 41 and clamping part 42 then, is described with reference to Fig. 3 and Fig. 4.Fig. 3 (a) is the sectional view of cone part 41 of the IIIa of enlarged drawing 2 (a), and Fig. 3 (b) is the sectional view of cone part 41 of the IIIb of enlarged drawing 3 (a).Fig. 4 is cone part 41 and the sectional view of clamping part 42 in the IV-IV line of Fig. 3 (a).
Shown in Fig. 3 (a), cone part 41 forms the toroidal with the inner peripheral surface 41a that forms taper, can be installed in rotatably on the Lift Part 3 (with reference to Fig. 2 (a)).The inner peripheral surface 41a of cone part 41 and the outer peripheral face 1a of sleeve pipe 1 set opposed to each other, and lower end side is near to the outer peripheral face 1a of sleeve pipe 1 side joint more more.Thus, through making the inner peripheral surface 41a downward side shifting of clamping part 42, can the outer peripheral face 1a of clamping part 42 to sleeve pipe 1 be pushed along cone part 41.
Clamping part 42 forms wedge shape, can swingingly be installed on the ring component 8c (with reference to Fig. 2 (a)) via linking parts 8d.In addition, clamping part 42 is as shown in Figure 4, on two sides, is formed with groove, the part of the pressing plate of chimeric cross section L word shape in this groove.
When clamping part 42 moves with respect to cone part 41 along with the moving of above-below direction (Fig. 4 paper vertical direction) of upper frame element 8, can make clamping part 42 move (with reference to Fig. 6) along the inner peripheral surface 41a of cone part 41.
Shown in Fig. 3 (b), on the outer peripheral face of cone part 41, rotation slot 41c hollowly is set to the lower, outer perimeter face side (Fig. 3 (b) right side) of cone part 41, this rotation slot 41c extends along the Zhou Fangxiang of cone part 41 continuously.In addition, on Lift Part 3, be equipped with and form annular outer ring member 3d with axle center identical with the axle center of the patchhole of Lift Part 3.On the inner peripheral surface of outer ring member 3d, to the inner peripheral surface side of outer ring member 3d (Fig. 3 (b) left side) rotation slot 3e is set hollowly, rotation slot 3e extends to the Zhou Fangxiang of outer ring member 3d continuously.Between rotation slot 41c and rotation slot 3e, a plurality of orbicule 41d of clamping rotationally, its result, cone part 41 can rotate with respect to outer ring member 3d with respect to the mode of outer shroud rotation with the interior ring of bearing.That is, by a plurality of orbicule 41d of clamping between cone part 41 and outer ring member 3d and constitute bearing.
At this, for example utilizing when forming rotation slot 41c with cone part 41 various parts, the binding parts that are used for the parts that are formed with rotation slot 41c (below be called " interior ring ") are linked to cone part 41 must be new parts, and components number is increased.In addition, in linking parts, each parts of interior ring and cone part 41 must have intensity, and institute is so that interior ring and cone part 41 wall thickness.Its result, ring and cone part 41 maximize and tubine machine 100 whole sizes increase the unfavorable condition that near therefore exist the ground boundary line and the construction on wall limit etc. can not carry out in making.
Relative therewith, in this embodiment, on the outer peripheral face of cone part 41, form rotation slot 41c, therefore need not be used for binding parts with interior hoop cone part 41 bindings, can reduce components number.In addition, with not do not link in ring not corresponding with cone part 41, the guaranteeing of intensity becomes easy, can realize the miniaturization of cone part 41.Its result reduces the whole sizes of tubine machine 100 and can carry out reaching near the ground boundary line construction etc. on wall limit.
Then, with reference to Fig. 5 the detailed formation of secondary clamping part 6 and the action of secondary clamping part 6 are described.Fig. 5 is the sectional view of the tubine machine 100 in the V-V line of Fig. 1, illustrates the upper surface of secondary clamping part 6.Fig. 5 (a) is the vertical view that does not grip the secondary clamping part 6 under the state of sleeve pipe 1, and Fig. 5 (b) is the vertical view that grips the secondary clamping part 6 under the state of sleeve pipe 1.
Shown in Fig. 5 (a) and Fig. 5 (b); The tape member 61 of secondary clamping part 6 forms circular shape; The patchhole 5c (with reference to Fig. 2 (a)) of the lower frame element of being inserted along sleeve pipe 15 sets a plurality of (being 2 in this embodiment), and these tape members 61 do, an end is by earth's axis dress each other.The hydraulic cylinder device 62 of secondary clamping part 6 is to make the total length and the quantity delivered of action oil change the device of (stretching) accordingly, and its both side ends is contained on the other end of tape member 61 by axle.
At this, explain that secondary clamping part 6 grips the action of sleeve pipe 1.Shown in Fig. 5 (a); Under the state that the total length of hydraulic cylinder device 62 is extended; Tape member 61 separates from the outer peripheral face 1a of sleeve pipe 1, make sleeve pipe 1 can be 5 movable with respect to lower frame element (with rotary middle spindle S as the rotation at center and moving) to the axis direction of rotary middle spindle S.Under this state, while rotating, pushed earthward by sleeve pipe 1, can excavated earth.
Then, shown in Fig. 5 (b), if the total length of hydraulic cylinder device 62 is shortened, then secondary clamping part 6 grips sleeve pipe 1.That is, by the shortening of hydraulic cylinder device 62, the distance shrinkage between the tape member 61 that sleeve pipe 1 sets, tape member 61 is to the outer peripheral face 1a of sleeve pipe 1 butt.And, further shortening through the total length that makes hydraulic cylinder device 62,1a applies pressing force to outer peripheral face, and sleeve pipe 1 is gripped by secondary clamping part 6.Its result even if main clamping part 4 (with reference to Fig. 2 (a)) is separated gripping of decannulation 1, through gripping sleeve pipe 1 by secondary clamping part 6, can prevent that sleeve pipe 1 is owing to deadweight is sunk.
In addition, the medial surface of tape member 61, crooked accordingly with the outer peripheral face 1a of sleeve pipe 1, the pressure that will be applied to so can grip the outer peripheral face 1a of sleeve pipe 1 equably on the outer peripheral face 1a of sleeve pipe 1 remains very low.Thereby, even if when guaranteeing to keep the power of sleeve pipe 1, also can the pressure restraining on the outer peripheral face 1a that be applied to sleeve pipe 1 etc. is very little and prevent sleeve pipe 1 distortion.
The excavation action of tubine machine 100 is described with reference to Fig. 6.Fig. 6; It is the sectional view of the state of the tubine machine 100 during expression is excavated; Fig. 6 (a); Be the sectional view that makes the tubine machine 100 of Lift Part 3 under the approaching state of lower frame element 5, Fig. 6 (b) is to make upper frame element 8 separate and the sectional view that grips the tubine machine 100 under the state that is disengaged of sleeve pipe 1 with respect to Lift Part 3; Fig. 6 (c) is the sectional view that gripping of sleeve pipe 1 was disengaged and made the tubine machine 100 under the state that Lift Part 3 separates from lower frame element 5.
At first, make the total length elongation of the hydraulic cylinder device 62 of secondary clamping part 6, tape member 61 is separated from the outer peripheral face 1a of sleeve pipe 1, remove gripping sleeve pipe 1 based on secondary clamping part 6.As stated, sleeve pipe 1 does, through between the inner peripheral surface 41a of its outer peripheral face 1a and cone part 41, inserting clamping part 42, makes sleeve pipe 1 connect to cone part 41, and the revolving force of hydraulic motor 21 can be passed to sleeve pipe 1 via cone part 41.At this, make cone part 41 rotations by hydraulic motor 21 and making under the state of sleeve pipe 1 rotation, side (Fig. 6 (a) downside) is mobile earthward to make the Lift Part 3 that cone part 41 is installed, thereby excavates vertical hole on the ground.The excavation depth (degree of depth in vertical hole) that should indulge the hole is dark more, and Lift Part 3 approaches ground more.In addition, Fig. 6 (a) diagram makes Lift Part 3 state of side shifting earthward.
