[0002] In daily production and life, the transportation, unloading and handling of goods are happening all the time. A large amount of handling work is limited by time, space, economy and other factors and cannot be carried out flexibly and conveniently. Usually, when encountering such a situation, most of the handling and unloading operations are carried out by multi-man operation. However, when encountering difficulties in manpower coordination, this kind of handling operation has great limitations. Therefore, there is an urgent need for equipment that can flexibly realize the loading and unloading of goods to solve this problem. Summary of the invention

[0003] The purpose of the present invention is to provide a heavy object loading and unloading device to address the deficiencies in the above-mentioned prior art. The device of the present invention can realize the unloading and carrying operations of heavy objects of a certain weight under the condition of single-person operation, and can be widely used in transportation, logistics, production and manufacturing processes, and fields that require heavy objects to be frequently carried from heights. It can also be installed on display equipment, transportation equipment and other products that require portable transportation as a key component.

[0004] The purpose of the present invention can be achieved by the following technical measures:

[0005] The heavy object loading and unloading transport device of the present invention comprises a nine-axis posture module fixed on the frame at an angle parallel to the ground, a left ground transport support wheel and a right ground transport support wheel installed at the middle front of the frame, and a ground transport direction wheel installed at the middle position of the rear end of the frame; a front upper transmission shield is connected to the front end of the frame; a front upper lifting motor, a front upper transmission screw rod, a front upper left transmission slide rod and a front upper right transmission slide rod are installed at the front side of the bottom of the front upper transmission shield through the front upper lifting motor, the front upper transmission screw rod, the front upper left transmission slide rod and the front upper right transmission slide rod arranged in the front upper transmission shield The middle transmission shield; the front lower transmission shield installed at the bottom of the front middle transmission shield by the front lower lifting motor, the front lower transmission shield and the front lower left transmission slide bar arranged in the front middle transmission shield; the rear upper transmission shield is connected to the rear end of the frame; the rear middle transmission shield installed at the bottom of the rear upper transmission shield by the rear upper lifting motor, the rear upper transmission screw rod, the rear upper left transmission slide bar and the rear upper right transmission slide bar arranged in the rear upper transmission shield; The rear lower lifting motor, the rear lower right transmission slide bar and the rear lower left transmission slide bar in the dynamic shield are installed on the rear lower transmission shield at the bottom of the rear middle transmission shield; the front mechanical lifting mechanism position sensor and the rear mechanical lifting mechanism position sensor are respectively installed in the middle position of the front lower transmission shield and the bottom of the rear lower transmission shield in a manner perpendicular to the ground; the front mechanical lifting mechanism left wheel and the front mechanical lifting mechanism right wheel are installed at the bottom of the front lower transmission shield, and the rear mechanical lifting mechanism left wheel and the rear mechanical lifting mechanism right wheel are installed at the bottom of the rear lower transmission shield; the front upper lifting motor, the front lower lifting motor, the front mechanical lifting mechanism position sensor, the nine-axis attitude module, the rear upper lifting motor, the rear lower lifting motor, the rear mechanical lifting mechanism position sensor, the battery power supply module, the front lifting button, the front lowering button, the rear lifting button, the rear lowering button, the overall lifting button, the overall lowering button, the emergency stop button, and the mode switching switch are connected to the corresponding interface of the main control board MCU through the corresponding cables.

[0006] The floor-standing transport direction wheel of the present invention can realize 360-degree rotation around the rotating axis.

[0007] The present invention completes the unloading process of the entire handling device from the vehicle body platform through the sequential transformation of the mechanical structure and the comprehensive judgment of the sensor signal; the operation flow of the unloading process is as follows: the front part of the vehicle including the front upper transmission shield is directed toward the outside of the vehicle body, and the device is pushed. After the left wheel of the front mechanical lifting mechanism extends out of the vehicle body, the front lowering button is clicked. After the main control board detects the front lowering button signal, the distance detection sensor signal of the front mechanical lifting mechanism and the nine-axis posture module signal are collected and a comprehensive judgment is made. If it is judged that the vehicle body has reached a horizontal state and the left wheel of the front mechanical lifting mechanism extends out of the vehicle body, the main control board The board controls the front upper lifting motor and the front lower lifting motor to work simultaneously, driving the front telescopic arm to extend and retract in the direction of the ground. When the distance detection sensor of the front mechanical lifting mechanism detects that the left wheel of the front mechanical lifting mechanism touches the ground, the system stops controlling the movement of the front telescopic arm; at this time, the heavy object loading and unloading handling device continues to be pushed to the outside of the car. When the left wheel of the rear mechanical lifting mechanism extends out of the car and the ground transport direction wheel is maintained above the car, click the rear descent button. After the main control board detects the rear descent button signal, it collects the rear mechanical lifting mechanism position sensor signal and the nine-axis attitude module signal and makes a comprehensive judgment If it is judged that the vehicle body has reached a horizontal state and the left wheel of the rear mechanical lifting mechanism has extended out of the car body, the main control board controls the rear upper lifting motor and the rear lower lifting motor to work simultaneously, driving the rear telescopic arm to extend and retract in the direction of the ground. When the rear mechanical lifting mechanism position sensor detects that the left wheel of the rear mechanical lifting mechanism has touched the ground, the system stops controlling the movement of the front telescopic arm. At this time, the heavy object handling platform has landed smoothly, and continues to push the heavy object handling platform out of the car body to complete the handling process of the heavy objects from the car body. The boarding process of the heavy object loading and unloading platform is just the opposite of the unloading process. When getting on the car, click the overall lifting button to control The loading and unloading platform for heavy objects is lifted to the height of the car body, and the handling platform is pushed to place the floor transport direction wheel on the car platform. Then, the rear lifting button is clicked, and the rear lifting machine is lifted upward as a whole. After the rear lifting mechanism is fully retracted, the handling device is pushed into the car. After the floor transport support wheel left and the floor transport support wheel right touch the car platform, the front lifting button is clicked. After the main control board detects this button signal, the front lifting machine is controlled to be lifted upward as a whole. After the front lifting mechanism is fully retracted, the overall transport device is pushed into the car body car, completing the boarding operation process of the entire device.

[0008] The beneficial effects of the present invention are as follows:

[0009] The present invention combines a mechanical lifting power device, a distance sensor module, a nine-axis sensor module, and a single-chip microcomputer control system; the control system realizes the corresponding functions of the entire on-board and off-board handling device through front and rear logical control of the mechanical device and comprehensive judgment of the sensor signals. The overall operation process is simple, convenient, and easy, and can easily realize the loading and unloading of heavy objects from the car platform, and has high market application value.
