Referring to fig. 7, as a preferred embodiment, the bottom plate 204 is formed by splicing three

plate bodies

2041, 2042, 2043, and both ends of each plate body are riveted with the first side plate and are reinforced and fixed by a triangular piece. When the rail transport cart carries cargo, the two sides of the bottom plate are stressed greatly, so that the

plate bodies

The first cam follower 302 is arranged in the first kidney-shaped hole 103 in a penetrating way, and the main eccentric disc 301 rotates to drive the jacking beam 102 to move up and down through the first cam follower 302; the first traveling wheel 101 moves up and down following the lifting beam 102. The jacking beam 102 is driven to move up and down based on the eccentric disc structure, so that the height of the first travelling wheel 101 is changed, the structure is reasonable, and the implementation is convenient.

When the jacking beam 102 moves up and down, the linear guide rail 106 and the slide block 107 move up and down relatively to provide positioning and supporting for the jacking beam 102. Two linear guide rails 106 are provided, in this embodiment, the two linear guide rails 106 are respectively provided at trisection positions of the jacking beam 102.

The carrier among the prior art mostly adopts the bearing to pass the location bearing structure of jacking roof beam. Because of the poor ability of the bearings to withstand lateral forces, the bearings are typically mounted close to the ends of the jacking beam, since both ends are only subjected to fore and aft forces. And because of the width specification of the bearing itself, the width of the jacking beam must match the width specification of the bearing.

Compared with a bearing, the linear guide rail has strong capability of bearing front and back forces and lateral forces, so the linear guide rail can be assembled at the middle section position on the jacking beam. So, the position of horizontal pole can be to both sides extension, makes track carrier inner space increase, is convenient for arrange equipment such as coil, motor. On the other hand, the linear guide rail is arranged on the side surface of the jacking beam, and has no requirement on the width of the jacking beam.

As an alternative embodiment, the lifting mechanism 3 further includes a silent chain (not shown), a secondary eccentric disc 307 and a second cam follower 308 connected with the secondary eccentric disc 307, the jacking beam 102 is further provided with a second kidney-shaped hole 104, and the second cam follower 308 is inserted into the second kidney-shaped hole 104. The main eccentric disc 301 and the sub eccentric disc 308 are connected by a silent chain transmission.

By means of a silent chain transmission, the rotational synchronization of the main eccentric disc 301 and the secondary eccentric disc 308 can be maintained.

On the other hand, the carrier of prior art often adopts belt drive, and when the carrier was applied to environment such as freezer, the belt was ageing easily for transmission effect variation. In the scheme, silent chain transmission is adopted, so that the precision is high, the bearing capacity is strong, the device can adapt to more harsh environments, the stability is high, and the service life is long.

In a preferred embodiment, the first kidney-shaped hole 103 has a length half of the circumference of the first cam follower 302, and the second kidney-shaped hole 104 has a length half of the circumference of the second cam follower 308. Thus, the rotational angles of the first and

second cam followers

302, 308 are 180 °.

Prior art trucks often employ a 360 ° rotation of the cam follower. Because a gap is reserved between the cam follower and the kidney-shaped hole, the upper gap and the lower gap are switched every time the cam follower rotates 180 degrees, and the upper gap and the lower gap are switched twice when the cam follower rotates 360 degrees, so that the error is large. In this embodiment, the error can be reduced by setting the rotation angle of the cam follower 308 to 180 °.

Referring to fig. 12, as a preferred embodiment, the cargo bed 5 has a central portion 501 that is recessed from opposite ends 502. When the modular lifting type track carrier works, the pallet is arranged on the goods carrying platform 5, goods are carried on the pallet, and the pallet is of a middle concave structure after being used for a long time. The middle part of the goods carrying table 5 is designed to be of a concave structure, so that the tray can be stably supported after the middle part of the tray is concave, the service life of the tray is prolonged, and the cost is saved.

When the lifting type direction-changing intelligent adjusting track truck of the embodiment is applied specifically, the cargo carrying platform 5 carries cargo, referring to fig. 13, when the cam follower is located at the first position (one side edge) in the waist-shaped hole, the lowest point of the second walking wheel 201 is higher than the lowest point of the first walking wheel 101. At this time, the first traveling wheel 101 lands on the ground and the second traveling wheel 201 suspends in the air, so that the lifting type rail transport vehicle can travel along the first direction. For example, the lifting type intelligent adjusting track truck with the reversing position walks along the direction of a walkway in a warehouse.

Referring to fig. 14, when the cam follower continues to move in the kidney-shaped hole, the lifting mechanism 3 drives the first frame module 1 to continue to move upward until the lowest point of the first traveling wheel 101 is higher than the lowest point of the second traveling wheel 201. At this time, the second road wheel 201 lands on the ground while the first road wheel 101 is suspended. At the moment, the lifting type reversing position intelligent adjusting track carrier can walk along the second direction. For example, the lift type intelligent adjustment track truck moves along a direction perpendicular to the direction of the walkway in the warehouse towards the rack.

Referring to fig. 15, when the lifting type direction-changing intelligent adjusting track transport vehicle moves to a target shelf and is located below a target cargo, the cam follower continues to move in the waist-shaped hole, the jacking beam 102 continues to move upwards, the cargo carrying platform 5 is jacked upwards to lift the cargo, and then the target cargo is transported to a target position according to a preset route.
