[0047] The utility model provides a rail trolley 100. The rail trolley 100 provided by the utility model can be applied to the field of storage equipment, such as in a stereoscopic warehouse, to solve the problem that the existing stereoscopic warehouse relies on a single intelligent handling device, such as a four-way shuttle vehicle to store and retrieve goods, resulting in the inability to ship goods in time and the inability to flexibly retrieve goods.

[0048] Among them, reference Figure 5 In order to apply the rail trolley 100 of the utility model, taking the stereoscopic warehouse as an example, a manual picking area 200 can be designed on the lower floor of the stereoscopic warehouse. A manual picking channel is arranged in the manual picking area 200 for picking and shipping.

[0049] In a preferred embodiment, Figure 1 As shown, Figure 1 The figure is a schematic diagram of a rail trolley 100 according to an embodiment of the present invention. The rail trolley 100 includes a mother trolley 110 and a child trolley 120. The mother trolley 110 is used to carry the child trolley 120, and the child trolley 120 with the goods is driven along the track to complete the delivery. The child trolley 120 is used to cooperate with manual picking up of goods, and the goods taken out manually are placed on the child trolley 120.

[0050] Specifically, refer to Figure 2 and Figure 3 .in, Figure 2 Schematic diagram of a mother trolley 110 in a rail trolley 100 according to an embodiment of the present invention. Figure 3 Schematic diagram of a sub-trolley 120 in a rail trolley 100 according to an embodiment of the present invention.

[0051] refer to Figure 2 The mother trolley 110 includes a mother trolley body 111, a lifting platform 113 and a mother push handle 114.

[0052] Specifically, a first wheel group 112 that can travel along the first track 131 is provided at the bottom of the mother vehicle body 111. The first wheel group 112 includes a plurality of running wheels 150. The number of running wheels 150 is not limited, and may be 4, 6 or other reasonable numbers. A lifting platform 113 is provided on the mother vehicle body 111, and is used to lift the child trolley 120, so that the child trolley 120 leaves the track to facilitate the towing of the mother trolley 110. The lifting platform 113 adopts existing technical equipment, and may be a hydraulic lifting mechanism or other equipment. A mother push handle 114 is provided on the mother vehicle body 111 for the user to apply force, and the user pushes and pulls the mother trolley 110 through the mother push handle 114.

[0053] refer to Figure 3 The sub-trolley 120 includes a sub-trolley body 121 and a sub-trolley handle 123.

[0054] Specifically, the sub-carriage body 121 can be detachably seated on the lifting platform 113. The bottom of the sub-carriage body 121 is provided with a second wheel set 122 that can travel along the second track 142. Similarly, the second wheel set 122 also includes a plurality of running wheels 150. The number of running wheels 150 is not limited, and can be 4, 6 or other reasonable numbers. The sub-push handle 123 is provided on the sub-carriage body 121 for the user to push and pull the sub-carriage 120.

[0055] It is understood that in order to better carry the goods, a pallet 124 may be provided on the top surface of the sub-carriage 121. In addition, the pallet 124 may have a hollow structure, which is extended along the length direction and / or width direction of the pallet 124, for example, in the form of a groove or slot, which can reduce the weight of the pallet 124 on the one hand, and facilitate the pallet 124 to be lifted by a forklift on the other hand.

[0056] The first track 131 on which the first wheel group 112 runs and the second track 142 on which the second wheel group 122 runs are perpendicular to each other or cross-arranged at other angles. Taking the stereoscopic warehouse as an example, the first track 131 and the second track 142 are perpendicular to each other.

[0057] In addition, the shapes of the mother vehicle body 111 and / or the child vehicle body 121 may not be limited, for example, a square vehicle body, other polygonal vehicle bodies, etc.

[0058] According to the rail trolley 100 of the present invention, when the sub-trolley 120 travels along the second track 142, the goods can be picked up as needed. After the goods are picked up, the sub-trolley 120 travels to the intersection of the first track 131 and the second track 142. Then the mother trolley 110 travels along the first track 131 and enters under the sub-trolley 120. The lifting platform 113 rises to lift the sub-trolley 120 loaded with goods to a certain height. Then the mother trolley 110 travels with the sub-trolley 120 along the first track 131 to the shipping area to complete the shipping.

[0059] Of course, to enable the mother trolley 110 to enter under the child trolley 120, the height of the lifting platform 113 in the initial state needs to be lower than the height of the bottom surface of the child trolley body 121, so that the lifting platform 113 in the initial state can extend under the child trolley body 121.

[0060] refer to Figure 4 The first wheel group 112 and the second wheel group 122 each include a plurality of running wheels 150. The running wheels 150 include a wheel body 151 that can run along a corresponding track, a guide wheel edge 152 that abuts against the inner side of the corresponding track, and a wheel frame 153. The guide wheel edge 152 is used to ensure that the mother trolley 110 and the child trolley 120 will not deviate when running along their respective tracks.

[0061] Continue to refer Figure 4 In order to prevent the driving wheels 150 of the mother trolley 110 and the child trolley 120 from derailing when passing through the intersection, the first track 131 and the second track 142 are at different heights at the intersection. The first track 131 or the second track 142 with a higher height is provided with a gap 160 for the driving wheels 150 on the lower track to pass through. Figure 4 In the illustrated embodiment, the second track 142 is shown to be lower, but it is understandable that the first track 131 may also be lower.

[0062] In a preferred embodiment, the distance between the wheel frame 153 of the running wheel 150 running on the second track 142 or the first track 131 with a lower height and the lowest point of the corresponding wheel body 151 is greater than the height difference between the first track 131 and the second track 142. With this design, the following situation can be prevented: when the running wheel 150 on the track with a lower height passes through the gap 160, the wheel frame 153 thereof interferes with the track with a higher height, so that the gap 160 needs to be widened, which may further require the running wheel 150 on the track with a higher height to be enlarged in size so as to pass through the gap 160 smoothly, or the wheel frame 153 structure of the running wheel 150 on the track with a lower height to be redesigned.

[0063] In summary, according to the rail trolley 100 of the utility model, the user can take out the goods and place them on the sub-trolley 120 as needed, and after the goods are taken out, the user can drive to a specific position, and then the mother trolley 110 enters under the sub-trolley 120, and the lifting platform 113 rises to lift the sub-trolley 120 loaded with goods, and finally the mother trolley 110 drives the sub-trolley 120 along the first track 131 to the shipping area to complete the shipment. The rail trolley 100 of the utility model can facilitate manual picking of goods, and can be used for loading and transporting goods on the ramps and lanes of the shelves of the stereoscopic warehouse, which can realize the storage and retrieval of goods, making the shipment more flexible.
