Abstract
The invention provides a stopping device of a slewing mechanism. The stopping device comprises a locking plate, a supporting shaft, and a stopping plate. A first end of the locking plate is arranged on the peripheral of a slewing frame. The locking plate extends outward along a radial direction of the slewing frame. The supporting shaft is arranged on a fixed fulcrum outside the slewing frame. An axis of the supporting shaft is parallel to a slewing axis of the slewing frame. The stopping plate is sleeved on the supporting shaft, and can swing around the supporting shaft between a first swing angle position and a second swing angle position. The stopping plate comprises a first stopping arm and a second stopping arm. When the locking plate rotates with the slewing frame, a second end of the locking plate pushes the first stopping arm or the second stopping arm, such that the stopping plate swings around the supporting shaft to the first swing angle position or the second swing angle position. The first stopping arm or the second stopping arm stops the locking plate from rotating. The invention also provides engineering machinery comprising the slewing mechanism stopping device.

The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the present invention.
Can find out by Fig. 1 and Fig. 2; The turret mount 2 that can rotate in a circumferential direction is installed on the permanent seat 4; The inhibiting device of swing type mechanism provided by the invention is used to limit the rotation angle range of turret mount 2, and is as shown in the figure, and the inhibiting device of this swing type mechanism comprises jam plate 1, pivot shaft 3 and positioning plate 5 etc.
Can be found out that by Fig. 1 to Fig. 4 first end of jam plate 1 is arranged on the periphery of turret mount 2, and jam plate 1 is along the extending radially outwardly of turret mount 2, promptly second end of jam plate 1 stretches out turret mount 2.Jam plate 1 can be one-body molded with turret mount 2, also can be one independently part be installed in (as shown in Figure 6) on the turret mount 2.Pivot shaft 3 is installed on the turret mount 2 exterior fixed pivots, for example can pivot shaft 3 be fixed on the permanent seat 4.The axis of pivot shaft 3 is parallel with the rotation axis of turret mount 2.Positioning plate 5 is set on the pivot shaft 3, and positioning plate 5 comprises first position limit arm 51 and second position limit arm 52.Understand easily, between first position limit arm 51 and second position limit arm 52, form a concave shaped portion 53, when jam plate 1 was in initial position, its second end was between first position limit arm 51 and second position limit arm 52.
When jam plate 1 rotates with turret mount 2; Second end of jam plate 1 promotes first position limit arm 51 or second position limit arm 52; Make positioning plate 5 rotate to first swash angle position or second swash angle position around pivot shaft 3, second position limit arm 52 or first position limit arm, 51 backstop jam plates 1 continue rotation.
Specifically combine with reference to figure 3, Figure 12 and Figure 14; When positioning plate 5 is in initial swash angle position and turret mount 2 and does anticlockwise motion, jam plate 1 with turret mount 2 along the anticlockwise direction rotation, at this moment; Second end of jam plate 1 promotes first position limit arm 51; Positioning plate 5 is done towards first swash angle position clockwise rotated, jam plate 1 breaks away from concave shaped portion 53 continued and rotates, and contacts until compressing with second position limit arm 52; And positioning plate 5 is limited in first swash angle position; Because first swash angle position is the end position that positioning plate 5 clockwise rotates, thus second position limit arm 52 just effectively backstops rotating counterclockwise of jam plate 1, and then the scope that rotates counterclockwise of turret mount 2 is strict controlled in 360 degree.When turret mount 2 after hours, contrarotation makes jam plate 1 and positioning plate 5 reply state shown in Figure 3.
In conjunction with reference to figure 3 and Figure 15, when being in initial swash angle position and turret mount 2, does when rotating positioning plate 5 along the pointer direction, and jam plate 1 is rotated in a clockwise direction with turret mount 2; At this moment, second end of jam plate 1 promotes second position limit arm 52, positioning plate 5 is done towards second swash angle position rotated counterclockwise; Jam plate 1 breaks away from concave shaped portion 53 continued and rotates; Contact until compressing, and positioning plate 5 is limited in second swash angle position, because second swash angle position is the end position that positioning plate 5 rotates counterclockwise with first position limit arm 51; So first position limit arm 51 just effectively backstops clockwise rotating of jam plate 1, and then the scope of clockwise rotating of turret mount 2 is strict controlled in 360 degree.When turret mount 2 after hours, contrarotation makes jam plate 1 and positioning plate 5 reply state shown in Figure 3.
Can learn that by preceding text the inhibiting device of swing type mechanism of the present invention increases mechanical position limitation on the basis of electrohydraulic control at present, fundamentally solve the possibility that causes the swing type mechanism angle of revolution to transfinite because of the external factor influence, make equipment more reliable.In addition, this inhibiting device is simple in structure and realize automatic spacing, need not manual operation.
Preferably; The hunting range of control positioning plate 5 can realize through following mode: combine with reference to figure 4 to Fig. 5, Fig. 7 to Figure 11; Positioning plate 5 is provided with the sleeve part 54 that cooperates with pivot shaft 3; One end of sleeve part 54 is spacing by the limited step on the pivot shaft 3 31, and the other end is spacing by the locking piece 6 that is mounted on the pivot shaft 3, and locking piece 6 is for example for being screwed onto the nut on the pivot shaft 3.On sleeve part 54, be provided with first otic placode 55 and second otic placode 56 that radially extend along sleeve part 54, pivot shaft 3 is provided with arcuate structure 32, the first otic placodes 55 and second otic placode 56 that are positioned at sleeve part 54 outsides and can in the opening scope of arcuate structure 32, rotates.Referring to Fig. 5, the two ends of arcuate structure 32 are respectively equipped with first draw-in groove 33 and second draw-in groove, 34, the first draw-in grooves 33 and are used for clamping first otic placode 55, the second draw-in grooves 34 and are used for clamping second otic placode 56.Particularly, when turret mount 2 rotated counterclockwise, positioning plate 5 clockwise rotated, and 56 servo-actuateds of second otic placode are until being blocked (referring to Figure 13) by second draw-in groove 34, this moment corresponding positioning plate 5 first swash angle position; When turret mount 2 clockwise rotated, positioning plate 5 rotated counterclockwise, and 55 servo-actuateds of first otic placode are until being blocked (referring to Figure 15) by first draw-in groove 33, this moment corresponding positioning plate 5 second swash angle position.
Need to prove; Pass through appropriate design; In the time of can making jam plate 1 break away from concave shaped portion 53, positioning plate 5 just in time is in first swash angle position of its second otic placode 56 and 34 clampings of second draw-in groove, perhaps second swash angle position of first otic placode 55 and 33 clampings of first draw-in groove; In when, to avoid occurring construction machinery and equipments under the turret mount 2 slight vibrations taking place, positioning plate 5 retrograde rotations and the effective problem of backstop jam plate 1.
Certainly, also can on sleeve part 54, only be provided with one and take the bigger otic placode of radian, obviously this otic placode take radian should be less than the opening radian of arcuate structure 32.Draw-in groove is not set on arcuate structure 32; And directly use the rotation of the two ends backstop otic placode of arcuate structure 32; Also can control positioning plate 5 relative pivot shafts 3 and in an angular range, swing, operate steadily, avoid positioning plate 5 to reverse but this kind embodiment need guarantee the construction machinery and equipment under the turret mount 2.
