[0042] I. When the device is in operation:

[0043] 1. Selection of moving modes:

[0044] (1) Electric - assisted mode: When the electric - assisted mode is selected, the hand - truck central controller 6 controls the driving motor 202c to start. The motor output gear on the output shaft of the driving motor 202c rotates, meshes with the driving gear on the driving shaft 202a, drives the driving shaft 202a to rotate, and thus makes the wheels two 202b fixed at both ends of the driving shaft 202a rotate to achieve the movement of the hand - truck. The wheel one 201b in the steering wheel assembly 201 can rotate flexibly to cooperate with the driving wheels to control the direction, facilitating movement within the construction site.

[0045] (2) Hand - pushing mode: If the hand - pushing mode is selected, the driving motor 202c does not work. Construction workers push the hand - truck by pushing the handle rod 304a, and both the steering wheel assembly 201 and the driving wheel assembly 202 can rotate flexibly under the action of hand - pushing.

[0046] (3) Bluetooth remote - control mode: When the Bluetooth remote - control mode is selected, within the line - of - sight range, the Bluetooth remote - control mode selection unit 701b of the intelligent terminal system 7 sends a Bluetooth signal to the hand - truck central controller 6, and the central controller controls the traveling mechanism 2 according to the signal instruction to achieve the remote control movement of the hand - truck, which is convenient for operation in some areas that are not easy to approach.

[0047] (4) Automatic driving mode: Through the automatic driving mode selection unit of the intelligent terminal system 7, the traveling path of the hand - truck is set or the automatic driving function is started; the hand - truck central controller 6 controls the traveling mechanism 2 according to the preset path or relevant algorithms to achieve automatic driving, which can be used for some repetitive transportation tasks to reduce manual operation.

[0048] 2. Unloading process:

[0049] When discharging is required, an instruction is sent to the trolley central controller 6 through the hydraulic control unit in the automatic discharging system 704 of the intelligent terminal system 7, and the central controller controls the hydraulic support mechanism 302 to start; one end of the hydraulic telescopic rod 302a is hinged to the support base one 302b on the end wall of the carriage bucket 301, and the other end is hinged to the support base two 302c on the vehicle frame 1. The hydraulic telescopic rod 302a extends, gradually lifting one end of the carriage bucket 301 hinged to the vehicle frame 1, and the carriage bucket 301 tilts. When the carriage bucket 301 tilts to a certain angle, the tipping discharge plate mechanism 303 is opened. The top of the discharge plate body 303a is hinged to the top of the discharge port, and the bottom is a free end. By pulling out the discharge plate bolt 305, the discharge plate body 303a is opened under the action of the gravity of the material, and the material is discharged from the discharge port.

[0050] 3. Monitoring process:

[0051] The monitoring camera 402 of the monitoring mechanism 4 is arranged on the installation platform 401 at the top of one end of the carriage bucket 301 where the handle mechanism is arranged; through the monitoring attitude adjustment unit in the monitoring system 703 of the intelligent terminal system 7, the pitching and left-right rotation angles of the monitoring camera 402 can be controlled to adjust the monitoring attitude and range, so as to comprehensively monitor the construction site or the situation around the trolley; at the same time, the voice call unit can make a call through the monitoring camera 402 to realize voice transmission, facilitating communication between construction workers or reminding personnel in a specific area, etc.

[0052] 4. Lighting process:

[0053] When constructing in an environment with insufficient light, an instruction is sent to the trolley central controller 6 through the lighting control unit in the lighting system 702 of the intelligent terminal system 7, and the central controller controls the lighting mechanism 5 to turn on to provide lighting, ensuring construction safety and the visibility of operations; the lighting control unit can separately control the opening and closing of each lighting lamp 501 to meet different lighting requirements.
