Description

Technical Field

[0001] The utility model relates to the technical field of cargo transfer vehicles, in particular to a movable automatic turnover vehicle for transferring cargo. Background Art

[0002] In logistics warehousing, AGV carts are often used to transfer goods. AGV carts can rely on their own automatic guidance system to transfer goods to the destination along a predetermined route without manual operation.

[0003] When the AGV is in use, it is moved to the bottom of the cargo, and then the lifting mechanism is used to push the pallet against the cargo. After the cargo is lifted away from the ground or the bracket, it is moved. After moving to the destination, the lifting mechanism is used to separate the pallet from the cargo, thereby completing the cargo transfer operation. When the AGV uses the pallet to transfer the cargo, although it is convenient to lift and lower the cargo, due to the lack of a blocking device for the cargo on the pallet, the cargo on the pallet is prone to fall off due to inertia during the start and stop of the AGV, especially when moving on a road with a certain slope, which increases the risk of cargo falling, thereby further reducing the safety of cargo transfer.

[0004] Therefore, a movable automatic turnover vehicle for transferring goods is urgently needed to solve the above problems. Utility Model Content

[0022] Example 1

[0023] See also Figure 1-Figure 5 , a movable automatic turnover vehicle for transferring goods shown in the figure includes an AGV trolley 101, a support plate 103 is connected to the AGV trolley 101 through four lifting rods 102, and also includes a blocking mechanism arranged on the support plate 103 for blocking and limiting the goods;

[0024] The blocking mechanism includes a mounting cavity 201 formed on the support plate 103, two mutually symmetrical through holes 202 are formed on two opposite inner walls of the mounting cavity 201, blocking rods 203 are slidably connected in the four through holes 202, and blocking plates 204 are fixedly connected at one end of the four blocking rods 203 away from the support plate 103, and a driving mechanism for driving the four blocking plates 204 is provided in the mounting cavity 201;

[0025] It should be noted here that: through the setting of the blocking mechanism, under the action of the driving mechanism and the rotating assembly, the blocking plate 204 is driven to rotate 90 degrees, so that the blocking surface of the blocking plate 204 is opposite to the goods or parallel to the pallet 103, thereby ensuring the convenience of lifting and lowering the goods. At the same time, the blocking effect of the blocking plate 204 is utilized to avoid the goods on the pallet 103 from falling due to inertia or changes in the running inclination when the AGV trolley 101 is started or stopped or moving on a road with a certain slope, thereby reducing the risk of goods falling and further improving the safety of goods transportation.

[0026] It is worth noting that: as a prior art, the specific structure and working principle of the AGV 101 have been mastered by those skilled in the art, and will not be elaborated herein.

[0027] See also Figure 4The four through holes 202 shown in the figure are provided with a rotating assembly for rotating the blocking plate 204, and the rotating assembly includes a push rod 302 fixedly connected to the inner wall of the through hole 202, and the other end of the push rod 302 has a rounded corner, and the side wall of the blocking rod 203 is provided with a spiral groove 301;

[0028] It should be noted here that the arrangement of the spiral groove 301 and the stop rod 302 facilitates the blocking rod 203 to rotate 90 degrees during its movement.

[0029] See also Figure 5 The side wall of the blocking rod 203 shown in the figure is provided with a first sliding groove 303 and a second sliding groove 304, and the ends of the first sliding groove 303 and the second sliding groove 304 close to each other are respectively connected to the two ends of the spiral groove 301;

[0030] It should be noted here that the position stability of the blocking plate 204 after rotation is maintained by providing the first sliding groove 303 and the second sliding groove 304 .

[0031] Working principle: When using the AGV 101 to rotate the goods, first move the AGV 101 to the bottom of the goods, and then, under the action of the lifting rod 102, push the pallet 103 to contact the goods and lift it away from the ground or the bracket. After lifting the goods away from the ground or the bracket, the AGV 101 moves. After moving to the destination, the lifting rod 102 is used to separate the pallet 103 from the goods, thereby completing the transfer operation of the goods.

[0032] When the pallet 103 lifts the goods, the four blocking rods 203 are pushed out of the installation cavity 201 by the driving mechanism and the guiding action of the stop rod 302 and the second sliding groove 304. In the process of the blocking rod 203 moving in the through hole 202, when the stop rod 302 and the spiral groove 301 abut against each other, the blocking rod 203 is driven to rotate 90 degrees under the mutual force, and the blocking plate 204 is further driven to rotate 90 degrees, so that the blocking plate 204 is The first sliding groove 303 is used to guide and limit the blocking plate 204, so that the blocking plate 204 can maintain its position stability after rotation. The blocking plate 204 can prevent the cargo on the pallet 103 from falling due to inertia or changes in the running inclination when the AGV 101 is started or stopped or moves on a road with a certain slope, thereby reducing the risk of cargo falling and further improving the safety of cargo transportation.

[0033] After the goods are transported to the destination, the lifting rod 102 is used to separate the pallet 103 from the goods, and under the action of the driving mechanism and the rotating assembly, the blocking plate 204 is rotated and made parallel to the pallet 103, so as to facilitate the AGV trolley 101 to be moved out of the goods or the bracket, thereby ensuring the convenience of lifting and lowering the goods.
