Nut 9 is fixed on the lower end of lifting slider 6, the screw thread fit in the screw thread of drive screw 8 and nut 8.The lower end of drive screw 8 is driven by gear 10 by elevating motor 7, when drive screw 8 rotates, by nut 9, drives lifting slider 6 up-and-down movements.The middle part of equalizing bar 3 is fixed on the upper end of lifting slider 6, when side lifting slider 6 upward movement, by the equalizing bar of this side and caterpillar wheel lifting.
Left side magnetic levitation device and right side magnetic levitation device are arranged in the both sides of vehicle frame 1, are positioned at the below of left side traveling gear and right side traveling gear train.Magnetic levitation device comprises electromagnet 11, magnet carrier 12, power transmission spring 13 and two lower tumblers 15, and power transmission spring 13 is stage clips.
The supporting base 14 that the both sides of vehicle frame 1 are arranged before and after respectively comprising two, supporting base 14 comprises spring perch 1401 and guide pillar 1402.
Electromagnet 11 is arranged on the middle part of magnet carrier 12, and power transmission spring 13 is arranged in the both sides, front and back of electromagnet 11.
On vehicle frame 1, comprise that 17,4 vertical shafts 17 of vertical shaft of 4 installation side guide wheels 16 are separately fixed at the position, front and back of vehicle frame 1 both sides, side guide wheel 16 is rotatably installed on vertical shaft 17.
The track 30 of suspension type monorail traffic system comprises left rail 30a and right rail 30b, and two caterpillar wheels 4 of left side traveling gear move on left rail 30a, and two caterpillar wheels 4 of right side traveling gear move on right rail 30b.The base portion equalizing bar 3 of train and caterpillar wheel 4 are arranged in the top of left rail 30a and right rail 30b, and the base portion of train lifting mechanism is arranged in the below of left rail 30a and right rail 30b.Between left rail 30a and right rail 30b, leave space, the top of the lifting slider 6 of side traveling gear and right side traveling gear is connected with equalizing bar 3 through space between left rail 30a and right rail 30b.
Track also comprises left side rail 30c and right side rail 30d, and left side rail 30c and right side rail 30d lay respectively at the below of left rail 30a and right rail 30b
The 30e that goes to the bottom of I-rail has the groove 30f that holds lower tumbler, and during electromagnet 11 work, the wheel rim 1501 of lower tumbler 15 enters the groove 30f that I-rail is gone to the bottom, and props up the 30e that goes to the bottom of I-rail.
On dolly, 4 left and right side guide wheels 16, respectively against the inner side operation of left side rail 30c and right side rail 30d, are convenient to dolly and are kept balance, reduce dolly transverse runout.
The suspension type monorail dolly of suspension type monorail traffic system is when craspedodrome state, and translation suspension bracket 201 moves on to midway location, makes dolly center of gravity in the centre of two trains.Before dolly enters track switch, first by electrical motor 19, move translation suspension bracket 201, make dolly gravity motion to the below of a side caterpillar wheel, then by train lifting mechanism, the train of opposite side is raised, caterpillar wheel and track disengage.Thereby realize, only have a side caterpillar wheel guiding.
The magnetic force of electromagnet 11 is controlled.At initial condition, electromagnet 11 does not have magnetic field, control elevating motor 7, make lower tumbler 15 approach the 30e that goes to the bottom of I-rail, going to the bottom of electromagnet 11 and I-rail only has very little gap between 30e, at this moment make electromagnet energising produce magnetic field, because track 30 consists of the little steel of magnetic resistance, so 11 pairs of tracks of electromagnet 30 produce magnetic attraction.Magnetic attraction equals three power sums, the gravity of electromagnet own, the elastic force of power transmission spring, the pressure of 15 couples of track lower surface 30e of lower tumbler.11 pairs of tracks 30 of electromagnet have magnetic force, and magnetic force is while being greater than the elastic force of power transmission spring and electromagnet self gravitation sum, by controlling elevating motor 7, can change the amount of compression of power transmission spring, thereby change the elastic force of power transmission spring.The pressure of top tumbler to guide rail, equals the elastic force that dolly gravity deducts power transmission spring.By changing the amount of compression of power transmission spring, can make top tumbler reduce the pressure of track, make dolly be equivalent to no-load run.Reach energy-conservation object.
As shown in Figures 9 to 11, before entering track switch, only have the electromagnet energising of a side to keep magnetic field.The electromagnet of opposite side has a power failure and does not produce magnetic field, and the electromagnet of power-off moves down under gravity and effect power transmission spring, and this side lower tumbler 15 departs from the groove 30f that I-rail is gone to the bottom, and is convenient to dolly and turns to.
The magnet sucking disc of magnetic levitation device of the present invention can be that electromagnet can be also permanent-magnet material, as your boron ferromagnetic material of iron.Adopt in the situation of permanent-magnet material, by changing the relative position of several permanent-magnet materials in magnet sucking disc, make magnet sucking disc externally show magnetic or without magnetic, realize magnetic force controlled.Also can be combined into magnetic-disc with electromagnet and permanent-magnet material, by controlling electromagnet, change the external magnetic force of magnet sucking disc.
The above embodiment of suspension type monorail traffic system of the present invention has following advantage:
1. fork is without active rail is set, and dolly self is controlled guiding, can in a short period of time, allow a large amount of dollies by fork, road.
2. elevated guideway is little, does not affect light and shines ground.
3. rail Ke factory batch manufacturing, on-the-spot installation.Also convenient mobile reconstruction.
4. vehicle structure is simple, and center of gravity is low, lightweight, the safety while having increased operation.
5. realize cost low, save the energy.Adopt guide rail guide wheel mode resistance little, semi-magnetic suspension mode is simple, and magnetic material use efficiency is high, can capable of reducing friction resistance, so native system can be saved mass energy.
