The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as restriction of the present utility model.
as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utlity model has multivariant crawler belt counterweight trolley synchronization structure, comprise bogey and a plurality of mass 2 for the carrying counterweight, wherein, bogey is mainly formed by two independently car bodies 10 that are arranged side by side, each car body 10 comprises crawler type walking mechanism 11, crawler type walking mechanism 11 is connected with car body 10 bottoms by pivoting support parts 12, form by a link span 13 between two car bodies 10 and be rigidly connected, link span 13 middle parts are connected with main frame 4 rear portions by a junction spare, mass 2 is placed in respectively on two car bodies 10 by preset ratio.
Principle of the present utility model is that the creeper undercarriage 11 of two car body 10 belows can be by 12 revolutions of pivoting support parts, structure formation state as shown in Figure 5 with main frame 4 synchronous advance and retreat time that the utility model is provided, form state as shown in Figure 6 with main frame 4 synchronous revolving the time, to facilitate the super-starting balance weight dolly with main frame 4 synchronizing movings.
On the technique scheme basis, wherein, each crawler type walking mechanism 11 comprises independently actuating device and independently control setup, and actuating device is used for driving crawler type walking mechanism 11 walkings, and control setup is used for controlling the speed of travel and the direction of travel of crawler type walking mechanism 11.
Because making, the own characteristic of crawler type walking mechanism 11 controls velocity of rotation difference that it turns to the crawler belt that only need make both sides, controlling its revolution need be only the crawler belt backward rotation on both sides, due to be provided with respectively on two car bodies 10 independently actuating device and independently control setup make two crawler type walking mechanisms 11 under car body 10 independently to be controlled and to drive, the adjustment crawler type walking mechanism 11 that is is more convenient.
Further, wherein, link mainly by the rear pole 31 that is connected with main frame 4 be connected two link rods 32 with link span 13 and form, hinged by hinge between rear pole 31 and two link rods 32.To make super-starting balance weight vehicle structure that the utility model provides be that main frame 4 has increased the mechanical characteristics requirement that degree of freedom has reduced the connect mechanism between main frame 4 and super-starting balance weight dolly when connecting by the hinged form of hinge, can also pivoting support parts 34 be set so that the degree of freedom increase of super-starting balance weight dolly in the junction of two link rods 32 and link span 13 based on same purpose.
On this basis, can angular transducer be set at the hinge place that two link rods 32 and back brace are done 31 connecting portions, to realize the collection to super counterweight trolley deviation angle.
When main frame 4 and super-starting balance weight dolly advanced in unison are moved back, the phenomenon of super-starting balance weight dolly skew can appear in the speed of two car bodies 10 of super-starting balance weight dolly when not mating, can the speed difference of two car bodies 10 of super-starting balance weight dolly be judged by angle that angular transducer induction two link rods 32 and rear pole 31 and hinge place form is set.
Further, wherein, be provided with an extensible member 33 between two link rods 32 and link span 13, the flexible position of extensible member 33 is provided with the distance of stretch out and draw back that rang sensor is used for induction extensible member 33.
In a single day the obstructed extensible member 33 that will cause of main frame speed and the little vehicle speed of super-starting balance weight occurs flexible when main frame 4 and super-starting balance weight dolly advanced in unison are moved back, can the difference of main frame speed and the little vehicle speed of super-starting balance weight be judged by the distance of stretch out and draw back that rang sensor induction extensible member 33 is set.
Further, wherein, each car body 10 is hinged with link span 13.Arrange like this and can avoid not damaging because two car bodies 10 do not cause link span 13 on same level, namely can adapt to uneven ground.
Also comprise master control set on the technique scheme basis, master control set is connected with the control setup of each crawler type walking mechanism 11, angular transducer is connected with master control set, and rang sensor is connected with master control set, and master control set also is connected with the control system of main frame 4 simultaneously.
As shown in Figure 5, when main frame 4 and the walking of super-starting balance weight dolly synchronous linear, take rear pole 31 as object of reference, the numerical value that master control set obtains according to the rang sensor on extensible member 33 detects the speed of main frame 4 and the relative speed of travel of super-starting balance weight dolly, and whether the data that obtain with the angular transducer of rear pole 31 and two link rod 32 connecting portion place hinge positions detect the super-starting balance weight dolly and wander off.When speed appears in walking, the control setup of the creeper undercarriage 11 under two car bodies 10 of the control system of bidirectional modulation main frame 4 and super-starting balance weight dolly so that main frame 4 and the little vehicle speed of super-starting balance weight always; When skew appears in walking, the control setup of only adjusting the creeper undercarriage 11 under two car bodies 10 of super-starting balance weight dolly first makes the speed of travel of two car bodies 10 difference occur adjusting skew, makes the speed of travel of two car bodies 10 consistent after the angular transducer induction is less than the angle value between rear pole 31 and two link rods 32.
As shown in Figure 6, when main frame 4 with when having surpassed the dolly synchronous revolving.Rear pole 31 place straight lines are reference, regulate synchronous revolving by the angle of two link rods 32 and rear pole 31 and two variablees of collapsing length of extensible member 33.During revolution, angle value is used for judgement super-starting balance weight carriage walking speed, and length value is used for judging that in the super-starting balance weight dolly, whether outside crawler belt wanders off, namely partially in or partially outside.
The utility model provides has multivariant crawler belt counterweight trolley synchronization structure, can all establish the crawler belt of pair of parallel on each crawler type walking mechanism 11, also can arrange manyly to parallel crawler belt on each crawler type walking mechanism 11, specifically can change according to the service condition of reality.
The invention also discloses a kind of hoisting crane that comprises the crawler belt counterweight trolley synchronization structure described in above-described embodiment, because the crawler belt counterweight trolley synchronization structure in this hoisting crane exists different from prior art, other parts are not drawn, those skilled in the art can grasp the structure of other parts of the hoisting crane that comprises above-mentioned crawler belt counterweight trolley synchronization structure in conjunction with prior art, do not repeat them here.
The above is only the utility model preferred embodiment; not thereby limit claim of the present utility model; so the equivalent structure that all utilization the utility model specification sheetss and diagramatic content have been done changes, and all is included in protection domain of the present utility model.
