Fig. 4 is that bassinet structure embodiment activity swinging kick structure is stretched out the enlarged diagram of activity swinging kick structure under the state under the utility model crawler type.
The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Bassinet structure can only be realized the lower vehicle-width of fixing under the existing crawler type, therefore be difficult to satisfy simultaneously the requirement of complete machine stability and transportation width and walking crossing ability, the utility model has adopted a kind of with bassinet structure under the crawler type of activity swinging kick structure, this activity swinging kick structure can turn to corresponding position according to the flexible state that drags oil cylinder, to change lower vehicle-width, adapt to different use scenes.
Fig. 2 a, 2b are respectively under the utility model crawler type bassinet structure and are in and drag the scheme drawing that oil cylinder is stretched state and full reduced state entirely.Can see that from Fig. 2 a, 2b are upper bassinet structure comprises vehicle frame body 2, is arranged on the track frame 1,4 and be arranged on and drag oil cylinder 3 between vehicle frame body 2 and the track frame 1,4 of vehicle frame body both sides under the crawler type.Vehicle frame body 2 extend into the activity swinging kick structure 5 that track frame 1,4 part are provided with rotatable predetermined angle.
On track frame 1,4, can be provided with activity swinging kick structure 5 and vehicle frame body 2 and stretch into the square through hole that track frame 1,4 part are complementary.The size of square through hole should match with the size that activity swinging kick structure 5 and vehicle frame body 2 extend into the part of track frame, to guarantee vehicle frame body 2 and the smooth and easy motion of activity swinging kick structure 5 in square through hole.
Dragging under the state that oil cylinder 3 stretches out fully, activity swinging kick structure 5 rotates to perpendicular to the position of track frame 1,4 length direction (can referring to Fig. 2 a and Fig. 3 b), extend into track frame 1, state that 4 part direction consistent because activity swinging kick structure 5 is in vehicle frame body 2 this moment, and activity swinging kick structure 5 can be passed through from the square through hole on the track frame 1,4, therefore under the effect that drags oil cylinder 3, track frame 1,4 can pull out with respect to activity swinging kick structure 5, so that activity swinging kick structure 5 enters in the square through hole.
Dragging under the state that oil cylinder 3 retracts fully, activity swinging kick structure rotates to and is parallel to track frame 1, the position of 4 length direction (can be referring to Fig. 2 b and Fig. 3 a), this moment is because activity swinging kick structure 5 has surpassed the width of square through hole inside after opening, therefore can assist to a certain extent to drag oil cylinder 3 limits track frame 1,4 the relative motions on the direction of stretching out at vehicle frame body 2, simultaneously activity swinging kick structure 5 rotates to and is parallel to track frame 1, during the position of 4 length direction, than the state that drags oil cylinder 3 and stretch out fully, the whole width of getting off this moment will reduce, and the length of the length of minimizing and activity swinging kick structure 5 self is relevant.Therefore under the effect that drags oil cylinder 3, track frame 1,4 can be with respect to the 5 inside indentations of activity swinging kick structure, so that activity swinging kick structure 5 stretches out from square through hole, and turn to the angle parallel with track frame 1,4 length direction.
Provide the activity swinging kick structure shown in the part of circle among Fig. 3 b among Fig. 4 and stretched out the enlarged drawing of state, the end that can see activity swinging kick structure 5 can be hinged on the part that the vehicle frame body extend into track frame, the plane that the hinge of hinge point can form perpendicular to the vehicle frame body is (referring to Fig. 3 a, Fig. 3 b), this version can so that active pendulum leg structure 5 can rotate round the hinge on the surface that forms perpendicular to the vehicle frame body, this rotation direction is convenient to activity swinging kick structure 5 and is being dragged under the state that oil cylinder 3 stretches out fully, can be supported track frame as the extension of vehicle frame body by himself, its lap of splice can cover the width of whole track frame, guarantees stress equilibrium.If adopt other rotation direction, for example with form surperficial parallel of vehicle frame body 2 or there are the inclination angles of spending less than 90, square through hole on the track frame 1,4 can not immediate roof come to activity swinging kick structure 5 at this moment, also just being difficult to form failure-free supports, even if also have the part that stretches into of part vehicle frame body 2 in the square through hole, then because the actual lap of splice is limited, then will inevitably cause the local stress between track frame and the vehicle frame body excessive.
In order to make activity swinging kick structure 5 can be more stable track frame 1,4 is supported, and can be smoothly by the square through hole on the track frame 1,4, activity swinging kick structure 5 width in vertical direction can be arranged to extend into track frame 1 with vehicle frame body 2,4 part width in vertical direction is consistent.As can see from Figure 4, the main force part on the activity swinging kick structure 5 comprises the upper surface of slide block 51 and the lower surface of base plate 53.
Shown in Fig. 2 a, have four Support Positions between vehicle frame body 2 and the track frame 1,4, each Support Position by vehicle frame body 2 extend into track frame 1, overlap and 5 pairs of track frames 1 of activity swinging kick structure, 4 of 4 support.Activity swinging kick structure can adopt the forms such as single-unit activity swinging kick, Dual Action swinging kick or four activity swinging kicks.Illustrated among Fig. 2 a more preferably to adopt and be two activity swinging kicks of opposite opened as activity swinging kick structure 5, this structure all more has superiority as activity swinging kick structure as activity swinging kick structure or by four activity swinging kicks with respect to the single-unit activity swinging kick, for example for the single-unit activity swinging kick, because the activity swinging kick will be supported track frame, therefore the intensity of activity swinging kick there is certain requirement, then must need to be designed to dimensionally larger activity swinging kick, like this will so that the activity swinging kick to rotate formed contour structures after stretching out larger, the width that exceeds track frame obviously is not to realize getting off the less optimal selection of overall width.And the support that track frame has been shared in the Dual Action swinging kick of opposite opened, can reduce dimensionally accordingly, it is less to cause the activity swinging kick to rotate formed contour structures after stretching out, the width (referring to Fig. 2 b) that can not exceed track frame, the whole width of getting off like this are exactly the width from the left hand edge of left track frame 1 to the right hand edge of right-hand track chiain frame 4.
Then higher to mach precision for four activity swinging kicks (and even more), difficulty of processing increases along with the increase of the quantity of activity swinging kick, certainly will require higher to the ability of Fabricating machinery and the technical ability of workers processing.
For two the activity swinging kicks that are opposite opened shown in Fig. 3 b, dragging under the state that oil cylinder stretches out fully, two activity swinging kicks rotate to respectively the position that relatively is 0 degree angle, for two the activity swinging kicks that are opposite opened shown in Fig. 3 a, dragging under the state that oil cylinder retracts fully, two relative opposite spins of activity swinging kick are to the position that is 180 degree angles.
Consider the actions such as bassinet structure may shake under the crawler type, inclination under work or travelling position, will avoid these reasons may cause the activity swinging kick to turn to undesirable position this moment, therefore can fixed orifice 52(all be set referring to Fig. 4 at the end of two activity swinging kicks), when two activity swinging kicks rotate to respectively the position that relatively is 0 degree angle, can pass two fixed orifices 52 in the activity swinging kick by bolt and be fixed.Can limit two activity swinging kicks by bolt and rotate round about, and can retraining two activity swinging kicks and vehicle frame body, to extend into the direction of part of track frame consistent, thereby slide in the square through hole easily on track frame.
Accordingly, fixed orifice 52(that can also be in the arranged outside of track frame and two activity swinging kicks is referring to Fig. 4) the bearing hole 6(that matches is referring to Fig. 2 a),, pass respectively two fixed orifice 52 and bearing holes 6 on the track frame in the activity swinging kick by bolt and be fixed (referring to Fig. 2 b) to the position that is 180 degree angles two relative opposite spins of activity swinging kick.
Bassinet structure is applicable to the engineering mechanical device of bassinet structure under all kinds of use crawler types under the crawler type that the front is introduced, and such as crawler crane, crawler type dynamic compaction machinery etc. can adapt to the operating mode of different in width requirement.
Bassinet structure embodiment and adopted the engineering mechanical device of bassinet structure under the utility model crawler type can reduce by the state of change activity swinging kick structure lower vehicle-width to adapt to transportation or advance or the operating mode of operation than the narrow road face under the crawler type of the present utility model also can increase by the state of change activity swinging kick structure lower vehicle-width and adapt to the stability requirement that guarantees complete machine under the operating mode such as lifting operation.
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.
