Example 1

The inventors have found the size and height of all trucks. The minimum height is about 80cm, so we set the height of the device to 80cm. The maximum grade of the trolley is measured and calculated and the length of the base channel 82 is set to 240cm, taking into account that the load in the trolley does not slip due to the inclination of the ramp. The length of the inclined rail is set to 180cm. If the truck 3 does not have guardrails or baffles, the cargo may slide down when the truck 3 runs on the rail. The height of the blind is set to 50cm because of the mass and the aesthetic appearance of the cargo trolley 3. The width of the truck was 1.8 meters, and when considering the width of the work, we measured and simulated the space where the goods were loaded and the space where the workers were loaded multiple times, and by considering the movement space of the workers we positioned the actual width of the product to 120cm. The space at both sides reserves 30cm space for workers. It can be seen from the cost that only 432 cells are needed to manufacture this machine, and that a procedure for loading the load requires approximately 8 to 10 persons before there is no load-on machine. At least half (more than four) of the people can be saved after improvement. The amount of work per day is approximately 8 hours, but some workers typically work for only 2-4 hours. Thus, we can save at least 8 people in one day and 240 people in one month. One person per day settles at 200 yuan payroll. One month can save 48000 yuan for one logistics company. According to 30 logistics companies with the same size on the market, the number of the logistics companies can be reduced by 1440000 yuan. And the cost of the designed product is about 400 yuan. The method greatly saves the expenditure of a plurality of small enterprises, greatly improves the working efficiency, reduces the labor intensity of workers, improves the working environment of the workers and improves the economic benefit of the enterprises.
