preferably; Said running truck bottom is recessed to form the current groove of the said broken line track of vertical tolerable towards the top; Said groove both sides have a pair of edge of symmetry; Be horizontally disposed with a pair of directive wheel respectively in bottom, said a pair of edge, said a pair of directive wheel can grasp said broken line track in opposite directions.
preferably, said electrical system can drive said two pairs of running trucks and move simultaneously, but the also said running truck operation of single driving.
are because the technique scheme utilization; The present invention compared with prior art has advantage and effect: the bottom at girder one end is provided with a pair of fixed supporting leg; The limiting plate of a pair of longitudinal direction is set in the bottom of the girder other end, a pair of movable supporting legs that supports girder is set between a pair of limiting plate, a pair of fixed supporting leg is supported on first crossbeam; In first crossbeam bottom a pair of running truck is set; Connect through pair of rotatable chassis horizontal hinge shaft between first crossbeam, a pair of running truck, a pair of movable supporting legs is supported on second crossbeam, below second crossbeam, cross member is set; Another is set to running truck in the cross member bottom; Connect through rotatable movable supporting legs horizontal hinge shaft between second crossbeam, the cross member, through another rotatable chassis horizontal hinge shaft is connected between cross member, the running truck, crane is when running into the broken line track; Movable supporting legs can be in motion between a pair of limiting plate with the distance between adjusting and the fixed supporting leg; The movable supporting legs horizontal hinge shaft is rotatable in order to regulating the direction of crane operation, two pairs of chassis horizontal hinge shaft scalable running trucks the direction of motion, crane can pass through the broken line track like this.
Description of drawings:
Accompanying drawing 1 is looked sketch map for master of the present invention;
Accompanying drawing 2 is the schematic side view of fixed supporting leg of the present invention;
Accompanying drawing 3 is the schematic side view of movable supporting legs of the present invention;
The specific embodiment:
are referring to shown in Figure 1; The trolley 2 that can move along girder 1 is set at girder 1 top of crane of the present invention; An end is provided with a pair of fixed supporting leg 3 in the bottom of girder 1, at the girder 1 bottom other end a pair of movable supporting legs 4 is set, and the top of a pair of movable supporting legs 4 has a pair of gauge regulating wheel 7 that distributes along girder 1 longitudinal direction; Both sides, top at a pair of movable supporting legs 4 are provided with a pair of limiting plate 6 that is connected girder 1 bottom; The long rails that cooperates with a pair of gauge regulating wheel 7 is set between a pair of limiting plate 6, forms one section longitudinal space 8 between a pair of limiting plate 6, when crane passes through the broken line track; A pair of movable supporting legs 4 can move in the longitudinal space 8 between a pair of limiting plate 6; Distance between a pair of like this movable supporting legs 4 and a pair of fixed supporting leg 3 can motor-driven variation in order to cooperate crane through the broken line track, be provided with in the bottom of crane in order to driving two pairs of running trucks 9,10 of crane operation, the bottom of two pairs of running trucks 9,10 offer towards above the current groove of the vertical tolerable broken line track of depression as 18; Groove forms a pair of edge of symmetry like 18 both sides; Be horizontally disposed with a pair of directive wheel respectively as 17 in bottom, a pair of edge, a pair of directive wheel 17 can grasp the broken line track in opposite directions, the stable operation when helping crane to pass through the broken line track like this; Be provided for driving the electrical system 5 of two pairs of running trucks 9,10 in an end of girder 1; Electrical system 5 can drive two pairs of running trucks 9,10 and move simultaneously, but the also wherein any running truck operation of single driving can get manipulating crane through the broken line track so flexibly.
are referring to shown in Figure 2; Passive first crossbeam 14 is set in the bottom of a pair of fixed supporting leg 3; First crossbeam, 14 bottoms are connected with a pair of running truck 9 through the chassis horizontal hinge shaft 13 that can rotate in the horizontal direction, the direction of advance that has made things convenient for crane through the broken line track time, to regulate a pair of running truck 9 like this.
