[0026] like Figures 1 to 7 The electric screw lifting vehicle shown in the figure comprises a base frame 1, and the front and rear ends of the base frame 1 are both equipped with walking wheels 24. A vertical bracket 2 is vertically installed on the base frame 1, and a driving device is installed on one side of the vertical bracket 2. A screw nut assembly 3 is installed on the other side plate of the vertical bracket 2 along its axial direction, and a lifting platform assembly is installed on the nut 4 in the screw nut assembly 3. A slide rail 5 is installed on one plate of the vertical bracket 2, and a slider 6 matching the slide rail 5 is installed on the back of the lifting platform assembly. A weighing sensor is installed on the lifting platform assembly, and the weighing sensor can monitor the lifting vehicle in real time. Loading situation: once it detects that the load exceeds the rated load, the system can sound an alarm or automatically stop the lifting operation, thereby avoiding equipment damage or safety accidents caused by overloading; in automated production lines, weighing sensors can provide accurate weight feedback to control the precise positioning or synchronous operation of the lift; through weighing sensors, operators can clearly know the current load, so as to make more reasonable operation decisions and improve work efficiency; during the operation of the lift, weighing sensors can continuously monitor load changes, which is important for preventing unexpected situations caused by sudden increases in load. A proximity switch 8 is installed on the upper part of the vertical bracket 2, and a switch component 9 that matches the proximity switch 8 is installed on the lifting platform assembly. When the lifting platform assembly rises to the highest point, the proximity switch 8 senses the switch component 9, thereby controlling the drive motor 17 in the drive device to stop.

[0027] like Figure 3 and Figure 5As shown, the vertical bracket 2 includes a vertical bracket body, and both sides of one end of the vertical direction of the vertical bracket body are provided with C-shaped parts, and the two C-shaped parts are arranged opposite to each other to form an installation area for installing a slide assembly. The inner side of the C-shaped part is a slideway 12, and the lower part of the vertical bracket body is also provided with an opening 14 for the belt in the driving device to pass through.
