As shown in fig. 1 and 2, the slider assembly 6 is mounted between the first fixed mounting plate 9 and the second fixed mounting plate 10 by an eccentric 11; as shown in fig. 1, 2 and 3, the eccentric wheel 11 is eccentrically mounted between the first fixed mounting plate 9 and the second fixed mounting plate 10, the eccentric wheel 11 can rotate relative to the sliding block assembly 6, and two ends of an axle of the eccentric wheel 11 are fixedly connected with bearings 14 on the first fixed mounting plate 9 and the second fixed mounting plate 10 respectively.

As shown in fig. 2, one end of the lifting power output shaft 12 is fixedly connected with a bearing 14 on the first fixed mounting plate 9, the other end extends to the inner side of the vehicle body, a synchronous lifting plate 13 is fixedly mounted on the lifting power output shaft 12, and the synchronous lifting plate 13 is a trapezoid plate body.

Referring to fig. 1 and 2, the active jack mechanism 3 is different from the linked jack mechanism 4 in that: the inner side end of the lifting power output shaft 12 of the active jacking mechanism 3 passes through the synchronous lifting plate 13 and is connected with the output shaft of the lifting motor in the interior of the sub-vehicle. The linkage jacking mechanism 4 is different from the active jacking mechanism 3 in that: the synchronous lifting plate 13 of the linkage jacking mechanism 4 is provided with a high-position limiting seat 7 and a low-position limiting seat 8, and the high-position limiting seat 7 and the low-position limiting seat 8 are of cylindrical structures. As shown in fig. 2, the synchronous lifting plate 13 of the active jacking mechanism 3 and the synchronous lifting plate 13 of the linkage jacking mechanism 4 are not on the same vertical plane, one end of the transmission rod 5 is rotatably connected with the synchronous lifting plate 13 of the linkage jacking mechanism 4 at the inner side thereof, and the other end of the transmission rod 5 is rotatably connected with the synchronous lifting plate 13 of the active jacking mechanism 3 at the outer side thereof.

As shown in fig. 1, 2 and 4, the slider assembly 6 includes a sliding plate 15 and guide rods 16, the sliding plate 15 is slidably mounted on the two guide rods 16, the sliding plate 15 is mounted inside the vehicle body frame 2 through the two guide rods 16, the sliding plate 15 can vertically slide relative to the vehicle body frame 2, a rectangular hole 17 matched with the eccentric wheel 11 is formed in the middle of the sliding plate 15, and walking wheels 18 are rotatably mounted on the outer sides of two ends of the sliding plate 15.

The working principle of the shuttle lifting and jacking interlocking device 1 is as follows:

the shuttle lifting and jacking interlocking device 1 can change the position of the sub-vehicle running wheels 18 relative to the sub-vehicle body frame 2; however, since the sub-trolley wheels 18 are always in contact with the rails and are rigidly supported by the rails, the position of the sub-trolley wheels 18 relative to the rails is unchanged, and therefore, when the sub-trolley wheels 18 change position relative to the sub-trolley body frame 2, the sub-trolley body frame 2 is lifted relative to the sub-trolley wheels 18 and the rails, thereby completing the picking and placing of the materials.

As shown in fig. 5, when the sub-vehicle of the shuttle is in a cargo state, the lifting power output shaft 12 of the active jacking mechanism 3 drives the synchronous lifting plate 13 of the active jacking mechanism 3 to rotate to the lower side of the first fixed mounting plate 9 of the active jacking mechanism 3 through the output shaft of the lifting motor; under the action of the transmission rod 5, the synchronous lifting plate 13 of the linkage jacking mechanism 4 synchronously rotates to the lower part of the first fixed mounting plate 9 of the linkage jacking mechanism 4. At this time, the eccentric wheels 11 of the active jacking mechanism 3 and the linkage jacking mechanism 4 rotate to the lowest position through the bearing 14 on the first fixed mounting plate 9, and meanwhile, the sliding plate 15 vertically slides to the lowest position relative to the guide rod 16, so that the sub-car body frame 2 moves downwards to the lowest position relative to the sub-car body frame 2, and the sub-car body frame 2 lifts up the goods relative to the sub-car body frame 18 and the track.

After the sub-car body frame 2 is loaded, the sliding force of the sliding plate 15 in the pre-vertical direction is transmitted to the eccentric wheel 11 to form the pre-upward rotating force of the eccentric wheel 11, but at the moment, the high-position limiting seat 7 is abutted with the transmission rod 5, so that the pre-upward rotating force of the eccentric wheel 11 is limited through the synchronous lifting plate 13 of the linkage lifting mechanism 4, the lifting power output shaft 12 and the bearing 14 on the first fixed mounting plate 9, and the sub-car body frame 2 is kept high, so that the bearing stability is met.

As shown in fig. 6, when the sub-vehicle body frame 2 is required to descend to enable the pallet material to descend and be placed on the upper surface of the sub-vehicle track, the output shaft of the lifting motor drives the lifting power output shaft 12 of the active jacking mechanism 3 to rotate 180 degrees clockwise. At this time, the lifting power output shaft 12 of the active jacking mechanism 3 drives the synchronous lifting plate 13 of the active jacking mechanism 3 to rotate above the first fixed mounting plate 9 of the active jacking mechanism 3; under the action of the transmission rod 5, the synchronous lifting plate 13 of the linkage jacking mechanism 4 synchronously rotates to the upper part of the first fixed mounting plate 9 of the linkage jacking mechanism 4. The eccentric wheels 11 of the driving jacking mechanism 3 and the linkage jacking mechanism 4 rotate to the highest position through the bearing 14 on the first fixed mounting plate 9, and meanwhile the sliding plate 15 vertically slides to the highest position relative to the guide rod 16, so that the sub-car travelling wheels 18 move upwards to the highest position relative to the sub-car body frame 2, and the sub-car body frame 2 descends to the highest position relative to the sub-car travelling wheels 18 and the track to drop the tray materials.

After the sub-car body frame 2 is unloaded, in order to avoid excessive clockwise rotation of the eccentric wheel 11, the lifting power output shaft 12, the synchronous lifting plate 13 and other parts of the active lifting mechanism 3 and the linkage lifting mechanism 4, the low-position limiting seat 8 is abutted with the transmission rod 5 to limit, so that lifting limiting locking of the body frame 2 is formed, and the lifting stroke of the body frame 2 is ensured to be accurate.

Further, in order to avoid rigid collision between the high-position limiting seat 7 and the low-position limiting seat 8 and the transmission rod 5, rubber protection sleeves can be sleeved on the high-position limiting seat 7 and the low-position limiting seat 8.

Specifically, as shown in fig. 1, 2, 5, 6 and 7, the number of the traveling wheels 18 on the single-side body frame 2 of the sub-vehicle in this embodiment is four, the four traveling wheels 18 are located on the same horizontal axis, each two traveling wheels 18 are mounted on the same sliding plate 15, the wheel shafts 19 of the traveling wheels 18 located at the rear side of the four traveling wheels 18 pass through the synchronous lifting plate 13 of the linkage lifting mechanism 4 and are connected with the output shaft of the traveling driving motor of the shuttle, and the sprocket 20 is fixedly mounted on the wheel shafts 19 of the four traveling wheels 18.

When the output shaft of the walking driving motor drives the wheel shafts 19 of the rear walking wheels 18 to rotate, the four walking wheels 18 synchronously rotate through the chain wheels 20 and the chains, so that the condition that the sub-vehicle walks on the track is met.

It should be noted that, the above embodiments are intended to protect the specific structure, the installation position, and the connection relationship between the components constituting the shuttle lifting and jacking interlocking device 1 of the shuttle lifting and jacking interlocking device 1; as for the position where the lifting motor and the traveling driving motor are arranged in the sub-vehicle, the specific way that one lifting motor is adopted to drive the two groups of shuttle lifting and jacking interlocking devices 1 to synchronously operate or the specific way that two lifting motors are adopted to respectively drive the two groups of shuttle lifting and jacking interlocking devices 1 to synchronously operate is not limited; the same principle specifically adopts one traveling driving motor to drive the wheels of the sub-vehicles on the two side vehicle body frames 2 to synchronously rotate, or adopts two traveling driving motors to respectively drive the wheels of the sub-vehicles on the two side vehicle body frames 2 to synchronously rotate, which is not particularly limited, and can be selectively installed according to actual requirements.
