[0019] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0020] Example

[0021] See also Figure 1-4 ,The utility model provides a technical solution: a dynamic load balancing monitoring device for a forklift;

[0022] This case aims to provide a forklift dynamic load balance monitoring device that facilitates real-time monitoring. Existing forklifts are prone to overloading or overloading during operation, which can lead to safety accidents and is very dangerous.

[0023] Based on the above issues, the components in this case include a forklift body 1, a fixing frame 2 is provided at the front end of the forklift body 1, a fork 3 is provided at the front end of the fixing frame 2, pressure sensors 4 are evenly embedded on the top of the fork 3, and a pull-wire displacement sensor 5 is installed at the bottom of the fixing frame 2. A pull rope is connected to one side of the pull rope, and a socket 6 is provided at one end of the pull rope. The socket 6 is connected to the rear side of the fork 3 through a connecting component;

[0024] A strain sensor 7 is adhered to one side of the fork 3, a data acquisition module 8 and a data processing module 9 are respectively provided at the cab of the forklift body 1, and a display screen 10 is provided at the cab of the forklift body 1;

[0025] The connection assembly includes a fixed base 11, a fixed cylinder 12 is installed at the bottom of the fixed base 11, the lower side of the fixed cylinder 12 is set to be conical, and the lower side of the fixed cylinder 12 is provided with an external thread. A rotating block 13 is sleeved on the outer side of the socket 6, and the inner wall of the rotating block 13 is provided with an inclined surface that matches the lower side of the fixed cylinder 12. The outer side of the inclined surface is provided with an internal thread. The rotating block 13 is threadedly connected to the lower side of the fixed cylinder 12;

[0026] It should be noted that in the present technical solution, before the forklift is operated, the fork 3 is in the initial position. At this time, the socket 6 is pulled, and the top of the socket 6 is inserted into the lower side of the fixed cylinder 12, and the rotating block 13 is rotated so that the inner wall inclined surface of the rotating block 13 is threadedly connected with the lower side of the fixed cylinder 12, and the lower side of the fixed cylinder 12 is pushed inward. Since a circle of notches 14 are provided on the lower side of the fixed cylinder 12, the lower side of the fixed cylinder 12 can be squeezed by the inclined surface and deformed, and the rubber anti-slip pad 15 on the inner wall of the fixed cylinder 12 is tightly attached to the socket 6, thereby completing the quick connection between the fixed seat 11 and the pull rope of the wire-type displacement sensor 5;

[0027] When the forklift is running, the pressure sensor 4 is used to monitor the pressure changes of the fork 3 in real time when it is under force, which can accurately determine the weight and load of the goods and ensure that the forklift operates within a safe load range;

[0028] When the fork 3 rises, it pulls the rope to move vertically. By measuring the displacement of the fork 3, the position and status of the cargo can be accurately determined, thereby ensuring that the forklift can accurately place the cargo at the designated location during transportation.

[0029] The strain sensor 7 is used to monitor the stress distribution of the fork 3 under the action of external force. By measuring the slight deformation of the surface of the fork 3, the stress state inside the fork 3 can be inferred;

[0030] The data collected by the sensor is then collected, organized, and transmitted by the data acquisition module 8, and processed and analyzed by the data processing module 9 to obtain the load and balance status of the forklift. The data acquisition module 8 includes a signal conditioning circuit, an analog-to-digital converter, and a microprocessor. The data processing module 9 includes a data receiving unit, a data processing unit, and a data storage unit. After the data processing is completed, the various data are visualized on the display screen 10 for the driver to view. When the data is abnormal, the alarm 17 sounds an alarm to remind the driver.

[0031] A protective cover 16 is provided on the outside of the strain sensor 7. The protective cover 16 is connected to the fork 3 by bolts to protect the strain sensor 7 and prevent the strain sensor 7 from being damaged by collision with the cargo.

[0032] In this technical solution, multiple data during the operation of the forklift are collected, processed and analyzed through the pressure sensor 4, the wire displacement sensor 5 and the strain sensor 7, so that the load condition and balance state of the forklift can be monitored in real time, effectively preventing the occurrence of safety accidents, optimizing operation efficiency and reducing maintenance costs.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
