[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Intelligent power supply management: The unique power supply mode of connecting head and conducting head in contact is adopted to realize intelligent power supply management. When the carrier carries materials and moves down, the connecting head automatically contacts the conducting head for power supply, ensuring the continuous operation of the self-propelled base; when the materials are taken away, the connecting head separates from the conducting head, and the self-propelled base stops supplying power, effectively avoiding energy waste. It solves the problem that the existing equipment is easy to be empty.

[0018] High degree of automation: The device can move automatically through the driving motor of the self-propelled base, without manual pushing or external track system, which greatly improves the degree of automation of material handling. This not only reduces labor costs, but also improves work efficiency, especially suitable for scenes that require frequent handling and complex and changeable working environment.

[0019] Flexibility and scalability: The device is designed to be flexible and can connect multiple self-propelled bases through a connecting plate to meet the needs of handling materials of different lengths and weights. At the same time, the layout of the moving slots and wire heads on the lifting plate can be adjusted according to the actual working environment to adapt to applications in different scenarios.

[0020] Stable and reliable material positioning: The loading plate and positioning plate on the loading seat are cleverly designed to automatically adapt to materials of different shapes and sizes to achieve stable and reliable positioning. This effectively prevents the material from shaking and sliding during transportation, and improves the safety of material handling.

[0021] Efficient and convenient material loading and unloading: The design of the trigger block enables the material to automatically move up and separate from the carrier when it reaches the specified position, realizing efficient and convenient material loading and unloading. This not only improves work efficiency, but also reduces the labor intensity of operators.

[0022] Environmental protection and energy saving: During the operation of the device, the energy consumption and carbon emissions are effectively reduced through intelligent power supply management and efficient material handling, which meets the requirements of modern industry for environmental protection and energy saving.

[0053] A vertical slide groove 501 is provided on the top of the object carrier 500, and the bottom of the loading plate 510 is slidably connected to the vertical slide groove 501, and a loading groove 1 is provided on the top of the loading plate 510; a horizontally arranged transverse slide groove 502 is provided on the side wall of the vertical slide groove 501, and a transverse plate 540 is slidably connected in the transverse slide groove 502, the bottom of the limiting plate 520 is fixed to the transverse plate 540, and the other end of the transverse plate 540 is connected to the loading plate 510 through an inclined rod 541, and the loading plate 510 and the transverse plate 540 are both rotatably connected to the inclined rod 541, a spring 551 is connected between the bottom inner wall of the vertical slide groove 501 and the bottom outer wall of the loading plate 510, a limiting opening 511 is provided on the top of the loading plate 510, and a limiting opening 2 521 is provided on the side wall of the limiting plate 520 near the top of the loading plate 510. When the loading plate 510 on the loading seat 500 is not loaded with goods, the spring 551 causes the loading plate 510 and the limiting plate 520 to move away from each other.

[0054] A mop fixing column 531 is fixed on the top of the limiting plate 520, and a flexible mop 530 is installed between the outer wall of the mop fixing column 531 and the outer wall of the top of the loading plate 510 away from the limiting plate 520.

When the limiting plate 520 and the loading plate 510 move away from each other to the maximum displacement distance, the flexible mop 530 is gradually tightened, and the material is moved out from the top of the loading plate 510.

[0055] A conveying method for a suspension conveying device of intelligent material handling equipment, which is used for the suspension conveying device of the above-mentioned intelligent material handling equipment, comprises the following steps: Step 1: placing the material on the top of the carrier plate 510; Step 2: the material drives the carrier plate 510 to move downward, and the limit plate 520 approaches the carrier plate 510 to limit the material; at the same time, the material drives the carrier seat 500 and the connecting column 400 to move downward, the terminal seat 241 drives the terminal head 240 to move upward, the terminal head 240 abuts against the wire head 120, and the driving motor 220 is energized to drive the self-propelled base 200 to move in the moving groove 110; Step 3: when the self-propelled base 200 drives the carrier seat 500 loaded with the material to move to the trigger block 600, the trigger rod 550 makes the carrier plate 510 move up, the carrier plate 510 and the limit plate 520 move away from each other, the material is taken out, the terminal head 240 is separated from the wire head 120, and the driving motor 220 stops supplying power.

[0056] Example 1: In a basic material handling scenario, such as a rectangular material:

[0057] After placing the material on the top of the carrier 500, the carrier plate 510 moves downward to make the limiting plate 520 approach it, the carrier plate 510 and the limiting plate 520 limit the material, the carrier 500 and the connecting column 400 move downward synchronously, the terminal seat 241 drives the terminal head 240 to move upward, and the driving motor 220 supplies power to realize the self-propelled function of the self-propelled base 200, thereby ensuring the stability of material transportation.

[0058] For example, materials that have been manually operated such as tearing the film of the packaged raw materials, manually assembling the components, and inspecting and punching the tires are placed on the carrier 500 for transportation;

[0059] Example 2: In the enhanced material handling scenario, such as tubular and cylindrical materials:

[0060] Two adjacent self-propelled bases 200 are connected by a connecting plate 300, the tube profile is placed horizontally, and its two ends are respectively placed in two adjacent carrier plates 510, and the limiting opening 1 511 and the limiting opening 2 521 on the top of the carrier plate 510 limit it;

[0061] When the moving groove 110 is an annular groove, the second mounting base plate 230 and the connecting plate 300 are clearance-matched, so that two adjacent self-propelled bases 200 can pass through the turning point of the moving groove 110;

[0062] If necessary, two self-propelled bases 200 are used to transport pipe profiles;

[0063] Example 3: In the intelligent material handling scenario, for example, intelligent transportation of tube profiles after manual inspection:

[0064] When the trigger rod 550 at the bottom of a carrier 500 located at the front end of the running track passes through the trigger block 600, one end of the material will be tilted and will not separate from the carrier 500. When the two carriers 500 simultaneously contact the trigger block 600 and move upward, the flexible mop 530 will be tightened and become inclined, so that the tubular profile is moved out from the carrier plate 510, and then it is transported to the loading place of the flying wing car through the guide plate, grid conveyor belt and other components.

[0065] It should be noted here that: since the flying wing vehicle may hit the grille conveyor belt, it is necessary to install infrared sensors on both sides of the door frame. When the vehicle reaches the grille conveyor belt, the engine cannot be turned off because the vehicle's own power is required to open the flying wing. When the flying wing is lifted to a certain height, the infrared sensor transmits the lifting height data to the controller. The controller receives the lifting height signal and determines whether the signal reaches the set range. If it reaches the predetermined range, the controller controls the engine to automatically shut down. When the flying wing is lifted, the pressure sensors on both sides of the door frame simultaneously transmit the pressure signal to the controller, and the controller disconnects the starter motor line.

[0066] When the vehicle starts, contact sensors are installed on both sides of the door frame of the flying wing car. When the door is closed, the contact sensor transmits the signal to the controller. The controller receives the contact signal and determines whether the signal reaches the set range. If it reaches the predetermined range, the controller opens the motor circuit. After the motor circuit is opened, the driver can use the key to turn on the motor and start the vehicle.

[0067] When the vehicle is moving and the wing is not raised, the vehicle is started and shut down according to the normal vehicle procedures.
