In a preferred embodiment, the y-direction wheel set driving unit 14 can drive the trolley 1 to move on the y-direction parallel track 6 synchronously through the control of the y-direction wheel set transmission unit by two pairs of y-direction wheels 5. For example, the y-direction wheel set transmission unit may be provided with first to seventh y-direction pulleys 12 to 12. The first y-direction belt wheel 12 to the fourth y-direction belt wheel are arranged on one y-direction side plate 34 on the same side, specifically, the first y-direction belt wheel 12 and the second y-direction belt wheel 11 are arranged on the upper side of the one y-direction side plate 34 on the same side, the third y-direction belt wheel and the fourth y-direction belt wheel are arranged on the lower end of the side y-direction side plate 34, and the two side y-direction wheels 5 are respectively and correspondingly arranged on the third y-direction belt wheel and the fourth y-direction belt wheel; the fifth y-direction belt wheel 39 to the seventh y-direction belt wheel are arranged on the other y-direction side plate 34 on the opposite side, specifically, the fifth y-direction belt wheel 39 is arranged on the upper part of one y-direction side plate 34 on the other side, the sixth y-direction belt wheel and the seventh y-direction belt wheel are arranged on the lower end of the y-direction side plate 34 on the other side, and the other two y-direction wheels 5 on the side are correspondingly arranged on the sixth y-direction belt wheel and the seventh y-direction belt wheel respectively.

Please refer to fig. 3-6. In a preferred embodiment, the jacking driving unit 15 can control the vertical displacement plate 35 to synchronously vertically lift along two x-direction sides through the jacking transmission unit. For example, the jacking transmission unit may be provided with the first to fourth gears 22 to 47. The first gear 22 and the second gear 20 may be disposed in pairs and engaged with each other, and disposed on the x-direction side plate 36 on one side, for example, may be disposed at a middle position of the x-direction side plate 36 and avoid interference with the first belt 29; the third gear 49 and the fourth gear 47 may also be provided in pairs and engaged with each other and provided on the other side x-direction side plate 36, for example, may be provided at a central position of the other side x-direction side plate 36 and avoid interference with the second conveyor belt 9. And, there is the first crank 44 on the side of the first gear 22, the first crank 44 can be connected movably (rotated) with a vertical displacement plate 35 below the same side through a first connecting rod 30, there is the second crank 48 on the side of the fourth gear 47, the second crank 48 can be connected movably (rotated) with another vertical displacement plate 35 below the same side through a second connecting rod 46.

Thus, when the jacking driving unit 15 drives the third gear 49 to rotate, the rotation torque can be synchronously transmitted to the fourth gear 47, the third link shaft 16, the second gear 20 and the first gear 22 through the third gear 49, so that the second crank 48 mounted on the fourth gear 47 and the first crank 44 mounted on the first gear 22 can be controlled to rotate around the respective gear centers, the second link 46 and the first link 30 connected to each other are driven to move up and down, and the vertical displacement plates 35 on two sides connected to the lower ends of the second link 46 and the first link 30 can also move up and down synchronously, so that the relative height of the x-direction wheel 4 mounted on the vertical displacement plate 35 can be changed.
Please refer to fig. 7-9. The jacking driving unit 15 can make the vertical displacement plate 35 respectively at the three heights shown in the figure by lifting and lowering, and control the vertical displacement plate 35 to stably stay at the heights, so as to realize the switching of the trolley 1 between the x-direction wheel set and the y-direction wheel set, so that the trolley 1 can run in a reverse direction, or the trolley 1 is in a stop state and cannot move. The method specifically comprises the following steps:
when the trolley 1 is located at the switching position between the x-direction parallel track 3 and the y-direction parallel track 6, the jacking driving unit 15 controls the second crank 48 (the first crank 44) on the fourth gear 47 (the first gear 22) to rotate to a position directly below the rotation center of the fourth gear 47 (the first gear 22), the first crank 44 and the second crank 48 will move down in physical position, so that the vertical displacement plate 35 on the corresponding side moves down relative to the trolley body, and the x-direction wheel 4 on the vertical displacement plate 35 moves down accordingly. At this time, the first crank 44 and the second crank 48 are stressed stably, and can play a good supporting role. At this time, the x-direction wheels 4 are lowered to a horizontal position lower than the y-direction wheels 5 (i.e. the lowest ends of the x-direction wheels 4 are lowered to be lower than the lowest ends of the y-direction wheels 5, as indicated by the dashed lines in the figure), and the x-direction wheels 4 fall on the x-direction parallel rails 3, so that the whole vehicle body is jacked up by the four x-direction wheels 4, and the y-direction wheels 5 are lifted along with the vehicle body to be separated from the y-direction parallel rails 6, so that the trolley 1 is switched from the original position on the y-direction parallel rails 6 to the x-direction parallel rails 3 and can move along the x-direction parallel rails 3, as shown in fig. 7.

At this time, the x-direction wheels 4 rise to a horizontal position higher than the y-direction wheels 5 (i.e. the lowest ends of the x-direction wheels 4 rise to be higher than the lowest ends of the y-direction wheels 5), in the process, the four y-direction wheels 5 gradually fall along the vehicle body and finally fall on the y-direction parallel rails 6, and the four x-direction wheels 4 are disengaged from the x-direction parallel rails 3, so that the trolley 1 is switched from being originally on the x-direction parallel rails 3 to the y-direction parallel rails 6 and can move along the y-direction parallel rails 6, as shown in fig. 8.
When the trolley 1 is located at the switching position between the x-direction parallel track 3 and the y-direction parallel track 6, the jacking driving unit 15 controls the lowest end of the x-direction wheel 4 to be level with the lowest end of the y-direction wheel 5 when the second crank 48 (the first crank 44) on the fourth gear 47 (the first gear 22) is rotated to be located at the position level with the rotation center of the fourth gear 47 (the first gear 22), and at this time, the x-direction wheel 4 is supported on the x-direction parallel track 3, and at the same time, the y-direction wheel 5 is supported on the y-direction parallel track 6, and the trolley 1 is braked (braked) and cannot move, as shown in fig. 9.
