Description

Technical Field

[0001] This invention relates to the field of AGV transportation technology, specifically to a cargo transport device for AGV trolleys. Background Technology

[0002] Automated Guided Vehicles (AGVs) are unmanned automated vehicles equipped with automatic guidance devices such as magnetic strips, tracks, or lasers. They travel along a planned path, are powered by batteries, and are equipped with safety protection and various auxiliary mechanisms. Typically, multiple AGVs, along with a control computer, navigation equipment, charging equipment, and peripheral auxiliary equipment, form an AGV system. Its main working principle is that, under the monitoring and task scheduling of the control computer, the AGV can accurately travel along the prescribed path, reach the designated task location, and complete a series of work tasks. The control computer can determine whether the AGV needs to automatically recharge in the charging area based on its own battery power.

[0003] In some warehousing and logistics operations in factories, AGVs are commonly used to transport goods. However, due to the limited carrying capacity of AGVs, in short-distance transport of the same batch of goods, ordinary AGVs can only transport goods by moving back and forth between the starting point and the destination. When multiple AGVs are transporting goods, traffic jams are likely to occur, resulting in poor transport continuity and relatively low transport efficiency. Summary of the Invention

[0046] Working principle:

[0047] During normal transportation, the lifting motor 205 is started, which drives the lifting push screw 206 to rotate. When the lifting push screw 206 rotates, it pushes the threaded cylinder 211, causing the active slider 207 to move to the right, thereby driving the driven slider 209 to move synchronously. When the driven slider 209 moves, the guide oblique hole 202 guides the push column 212, causing the driven slider 209 to move upward, thereby causing the push wheel 213 to push the lifting enclosure mechanism to rise, so that the enclosure angle 303 protrudes from the bearing frame 101 to form an enclosure. Then, the goods are placed above the bearing frame 101 for transportation.

[0048] When transporting goods over short distances in the same batch, multiple devices are connected end-to-end at the starting and ending points of the goods. The lifting motor 205 is started, and the lifting motor 205 drives the lifting push screw 206 to rotate in the opposite direction. When the lifting push screw 206 rotates, it pushes the threaded cylinder 211, causing the active slider 207 to move to the left, thereby driving the driven slider 209 to move synchronously. When the driven slider 209 moves, the guide oblique hole 202 guides the push column 212, causing the driven slider 209 to move downward, thereby causing the push wheel 213 to push the lifting enclosure mechanism down, causing the enclosure angle 303 to retract and enclose the supporting frame 101. Then, the electromagnet 410 on the side of the rear device close to the front device is energized. The electromagnet 410 attracts the armature ring 408, causing the positioning insert 407 to extend out of the positioning slide cylinder 406 inside the device and insert into the positioning slide cylinder 406 inside the front device, thereby forming a docking and preventing the device from easily deviating to the side in the middle.

[0049] Then, the conveyor motors 111 and dust removal fans 118 on all device surfaces are started. After the conveyor motors 111 start, they drive the conveyor worm gear 115 to rotate through the conveyor worm 113. When the conveyor worm gear 115 rotates, it drives the conveyor roller 105 to rotate through the conveyor shaft 104, thereby driving the conveyor belt 106 to move. At the same time, the conveyor shaft 104 drives the driven bevel gear 112 through the active bevel gear 114 to feed back the rotation speed to the speed sensor 110. Then, the rotation speed of the conveyor motors 111 is adjusted so that the movement speed of each conveyor belt 106 is consistent. When the dust removal fans 118 start, they continuously pump the air intake of the side exhaust trough 117 downward, so that the surface of the moving conveyor belt 106 is brushed by the cleaning brush 102 and then cleaned by the air blower, ensuring the cleanliness of the surface of the conveyor belt 106.

[0050] The goods are then placed on the conveyor belt 106 near the starting point, and the goods are continuously transported to the destination by the movement of the conveyor belt 106, thus realizing the transportation of goods.
