The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Showing 9 among Fig. 8 and the Tu, what go out is the scheme drawing of the 3rd anti-hypsokinesis slide rail 1, the coupled condition birds-eye view of the anti-squat system shown in Figure 10 and principal arm.As Fig. 8, Fig. 9 and shown in Figure 10, the anti-squat system of principal arm 2 comprises the 3rd anti-hypsokinesis slide rail 1, the 3rd anti-hypsokinesis oil cylinder 4, pulley 5 and the 3rd cylinder bracket (not shown among Figure 10, can with reference to Fig. 2).Wherein: the 3rd anti-hypsokinesis slide rail 1 is welded on the both sides of turntable 3.The upper end of the 3rd anti-hypsokinesis oil cylinder 4 is connected with principal arm 2 bearing pins, and the bottom of the 3rd anti-hypsokinesis oil cylinder 4 arranges pulley 5, and the bottom is by pulley 5 and the 3rd anti-hypsokinesis slide rail 1 sliding block joint.The 3rd cylinder bracket is connected between the 3rd anti-hypsokinesis oil cylinder 4 and the principal arm 2.
When the pulley 5 of the 3rd anti-hypsokinesis oil cylinder 4 bottoms touches the 3rd anti-hypsokinesis slide rail 1, chute on the pulley 5 blocks the head of the 3rd anti-hypsokinesis slide rail 1, beginning begins to slide along the 3rd anti-hypsokinesis slide rail 1, until supporting to the 3rd anti-hypsokinesis slide rail 1 afterbody, at this moment, the 3rd anti-hypsokinesis oil cylinder 4 begins to shrink, along with principal arm 2 elevations angle increase, the second anti-hypsokinesis oil cylinder 4 is contracted to the dieback state, the elevation angle between principal arm 2 and the turntable 3 is controlled within safe elevation coverage, thereby played the effect that prevents principal arm 1 excessive hypsokinesis.
What Fig. 8 and Fig. 9 showed is the structural representation of the 3rd anti-hypsokinesis slide rail 1 one embodiment, and in this embodiment, the 3rd anti-hypsokinesis slide rail 1 comprises groove inlet section 11, cruising phase 12 and restriction protrusion 13, and groove inlet section 11, cruising phase 12 and restriction protrusion 13 link into an integrated entity.Groove inlet section 11, cruising phase 12 and restriction protrusion 13 can create by casting, forging or Shooting Technique are one-body molded.
In above-described embodiment, same as the prior art, groove inlet section 11 is arranged on the head of cruising phase 12, and restriction protrusion 13 is arranged on the afterbody of cruising phase 12.When the 3rd anti-hypsokinesis oil cylinder 4 slides along groove inlet section 11 past afterbodys and cruising phase 12, when supporting to restriction protrusion 13, restriction protrusion 13 stops that the 3rd anti-hypsokinesis oil cylinder 4 further travels forward, and controls within safe elevation coverage the elevation angle between principal arm 2 and the turntable 3.
The utility model mainly is that chute width that the thickness at existing anti-hypsokinesis slide rail only is slightly less than pulley makes that the gap is little and causes into groove success ratio problem on the low side and propose, therefore, the utility model reduces the thickness of groove inlet section 11, make it less than the thickness of cruising phase 12, be about to groove inlet section 11 and make thin plate into, thereby form a kind of anti-hypsokinesis slide rail of variable section, thus, the thickness of groove inlet section 11 is little more a lot of than the chute width of pulley 5, the chute of pulley 5 when the 3rd anti-hypsokinesis oil cylinder 4 is gone into groove and the gap between the groove inlet section 11 have been increased, even if the 3rd anti-hypsokinesis oil cylinder 4 produces certain deviation angle, groove inlet section 11 also is to snap in very easily in the chute of pulley 5, therefore, improve the groove success ratio of going into of the present utility model, thereby improved the reliability of anti-squat system.
As a distortion of above-described embodiment, the thickness of the head of cruising phase 12 reduces from back to front gradually, thereby forms pyramidal structure, and this pyramidal structure provides a transition for the chute of pulley 5 snaps in cruising phase 12, is beneficial to pulley 5 and slips into cruising phase 12 smoothly.Because the part outside the head of cruising phase 12 is to wait the thickness of slab structure, and this thickness is identical with the thickness of slide rail in the prior art, is slightly larger than the chute width of pulley 5, so the planing stability of pulley 5 provides help.
Part outside the afterbody of groove inlet section 11 is for waiting thickness of slab structure, and the requirement of this thickness can be carried the 3rd anti-hypsokinesis oil cylinder 4 as long as satisfy.
In the various embodiments described above, restriction protrusion 13 is the indent arcwall face with the joint face of cruising phase 12 afterbodys, this indent arcwall face makes between the 3rd anti-hypsokinesis oil cylinder 4 and the principal arm 2 and fierce bump can not take place because of stopping suddenly for the stop motion of the 3rd anti-hypsokinesis oil cylinder 4 provides a buffering plane.
In the various embodiments described above, because the 3rd anti-hypsokinesis slide rail 1 is welded on the upper surface of turntable 3, the groove inlet section 11 shown in the figure produces bending, and purpose arranges for the step part of the upper surface that agrees with turntable 3.
Shown in Figure 11 is anti-squat system and the coupled condition birds-eye view that has surpassed mast 7.As Fig. 8, Fig. 9 and shown in Figure 11, the anti-squat system that has wherein surpassed mast 7 is identical with the structure of the anti-squat system of principal arm, also comprise the pulley 9 of the 4th anti-hypsokinesis slide rail 6, the 4th anti-hypsokinesis oil cylinder 8, the 4th anti-hypsokinesis oil cylinder 8 bottoms and the 4th cylinder bracket (not shown among Figure 11, can with reference to Fig. 3).Wherein: the 4th anti-hypsokinesis slide rail 6 is welded on the both sides of turntable 3.The upper end of the 4th anti-hypsokinesis oil cylinder 8 with surpass mast 7 bearing pins and be connected, the bottom is passed through pulley 9 and the 4th and is prevented hypsokinesis slide rail 6 sliding block joints.The 4th cylinder bracket is connected the 4th anti-hypsokinesis oil cylinder 8 and has surpassed between the mast 7.
The structure of the 4th anti-hypsokinesis slide rail 6 is identical with the structure of the 3rd anti-hypsokinesis slide rail 1, is not described in detail in this.
The utility model also provides a kind of crawler crane, and it comprises the anti-squat system in the various embodiments described above.The other parts of described crawler crane can be with reference to prior art, and this paper no longer launches to describe.Behind the anti-squat system that crawler crane employing utility model provides, make anti-hypsokinesis oil cylinder go into groove and become simple, anti-hypsokinesis oil cylinder is gone into the groove success ratio and is improved, thereby has improved the reliability of crawler crane.
In order to narrate conveniently, the direction of above mentioning " preceding " is consistent with the slide rail right direction shown in the accompanying drawing, " back " is consistent with the slide rail left direction shown in the accompanying drawing, that is to say, vertical direction refers to from groove inlet section 11 to cruising phase 12 direction.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
