8. The electric lifting cart according to claim 7, wherein: anti-disengaging mechanism (32) are including anti-disengaging keeps off frame (321) and lift driving motor (322), one side of anti-disengaging keeps off frame (321) is equipped with rack (322), drive wheel (323) are located to the output of lift driving motor (322), rack (322) and drive wheel (323) meshing.
9. The method of operating an electric high-lift truck according to any one of claims 1 to 8, wherein: the specific working method is as follows: 1): a driver moves a vehicle to the edge of goods to be transported, then a turnover driving plate (6) is driven by a turnover driving cylinder (4) to turn over a first fork frame (31) and a second fork frame (32) to horizontal positions, and a height detection device (311) detects the positions of the goods;
2): then the width detection device (333) detects the width of the article to be forked, transmits the detected data to the control device and judges whether the width of the article to be forked is matched with the width of the current first fork frame (31);
3): if matched, the goods are forked on the fork plates through the fork plates in the first fork frame (31);
4): then the anti-falling mechanism (32) starts to work, namely the lifting driving motor (322) drives the driving wheel (323) to rotate, the driving wheel (323) drives the rack (322) to move relative to the driving wheel in the rotating process, and the anti-falling blocking frame (321) moves upwards to a height higher than the bottom edge of the article under the driving of the rack (322);
5): then the driving cylinder (22) drives the sliding seats (21) on the two sides of the first mounting plate to move upwards along the lifting track so as to drive the first fork frame (31) upwards;
6): if the data detected in the step 2) show that the width of the article to be forked is not matched with the width of the current first fork frame (31), the sliding block is driven to move along the electric guide rail (24) through the driving cylinder, the distance between the two fork plates (4) is adjusted, and after the distance is adjusted to a proper position, the goods are forked on the fork plates;
7): repeating the steps 4 to 5;
8): in the process that the first fork frame (31) moves upwards, the height detection device (331) detects the height to be measured of the second fork frame (32) and judges the height of the first fork frame required to move upwards;
9): after the first fork frame moves up to the height judged in the previous step, the second fork frame (32) starts to work;
10): the width detection device (333) detects the width of the article to be forked, transmits the detected data to the control device and judges whether the width of the article to be forked is matched with the width of the current second fork frame (32);
11): if so, forking the goods onto the fork plate through the fork plate in the second fork frame (32);
12): then the anti-falling mechanism (32) starts to work, namely the lifting driving motor (322) drives the driving wheel (323) to rotate, the driving wheel (323) drives the rack (322) to move relative to the driving wheel in the rotating process, and the anti-falling blocking frame (321) moves upwards to a height higher than the bottom edge of the article under the driving of the rack (322);
13): if the data detected in the step 2) show that the width of the article to be forked is not matched with the width of the current second fork frame (31), the sliding block is driven to move along the electric guide rail (24) through the driving cylinder, the distance between the two fork plates (4) is adjusted, and after the distance is adjusted to a proper position, the goods are forked on the fork plates;
14): repeating steps 11 to 12;
15): then, the driver drives the truck with the fork goods to a designated position, and the first position detection sensor (15) and the infrared sensor (332) start to work in the moving process of the truck;
16): if the first position detection sensor (15) detects that the carried goods are higher than the position of the driver, the first position detection sensor instructs a lifting driving mechanism (75) to drive a lifting platform (74) to lift upwards, and drives a lifting driving chair (72) to lift upwards in the lifting process of the lifting platform (74), so that the driver can see the road condition in front;
17): meanwhile, the reversing radar (75) starts to work, road conditions are displayed through the display screen 71, and when the distance between the reversing radar and an obstacle reaches a dangerous distance, an alarm device starts to give an alarm;
18): after the goods are transported to the designated position, the goods are discharged, then the motor drives the gear to rotate, and the gear is arranged
The driving rack drives the second section of fork plate (302) to move towards the first section of fork plate (301) to contract the first section of fork plate;
19): after the first fork frame (31) and the second fork frame (32) are retracted to the right position, the overturning driving plate (6) is driven by the overturning driving cylinder (4) to overturn the first fork frame (31) and the second fork frame (32) to be in a vertical state.
