The concept of the half coefficient of good transmission performance and efficiency is important, and efforts should be made to make the designed mechanism compact and reasonable in order to have practical significance. In the past, technicians often used modern design theories such as the composite method and penalty function method in computer languages to optimize design. However, due to the lack of standard subroutines to call, they had to program themselves and debug them before proceeding with optimization design. When any statement in the program is incorrect, or even improperly debugged, it may lead to incorrect results. Therefore, this article can achieve the design of hydraulic cylinder driven lifting mechanism by calling relevant functions in the chemical tool box of the river, using only more than 10 lines of river 1 recognition 8 statements. The main parameters and hydraulic transmission working principle of the pedal platform handling vehicle are as follows: The pedal 1 handling Zha 1 series products use hydraulic pumps to drive the platform to rise, which can adjust the height difference during cargo operation and is suitable for lifting and moving goods in various industries. It makes heavy lifting work easy and fast. Its advantages are smooth lifting and easy operation. Flexible operation, safe use, no sparks or electromagnetic fields generated. The required parameters for the transport vehicle are a rated load of 300 and the number of foot pedals for the cargo; The hydraulic lifting mechanism of the 32 foot platform handling vehicle is actually a double slider rocker mechanism. Mechanism principle 2: The lifting mechanism consists of a slider 6 and a rod 37, forming a rocker mechanism, and a double slider rocker mechanism consisting of a slider 14 and a rod 523. The driving force is exerted by a hydraulic cylinder piston fixed on the trolley through a double slider rocker mechanism, thereby lifting the heavy object. Its hydraulic transmission principle is small. Human activity cold 6 and joystick 3 are hinged at 8 o'clock. When stepping on the pedal, the small piston 1 moves up and down. When the small piston moves upward, hydraulic oil enters the lower chamber of the small hydraulic cylinder through one-way valve 3 in the pipeline. When the pedal is stepped on, the small piston moves down, and the oil in the lower chamber is input into the lower chamber of the large hydraulic cylinder through the FF one-way valve 2. Due to the action of oil pressure, the one-way valve 3 closes and blocks the oil in the tank, causing the large piston 6 to move upward, pushing the rocker arm 3 to swing. Repeatedly stepping on the pedal, the oil continuously enters the lower chamber of the large cylinder, pushing the large piston to slowly rise and thus the platform to rise. Rotate the unloading valve to return hydraulic pressure to tank 4, unload the large piston, and lower the platform. 1. Foot pedal type 2. Principle of lifting mechanism. Platform handling vehicle 146. Sliding block 235. Rod 2.2 Static analysis of the lifting mechanism of the platform vehicle. Due to the low movement speed of each component of the lifting mechanism, the inertia and friction forces of each component are not considered. The algebraic method is used to analyze the position of the lifting mechanism of the handling vehicle. The mechanism principle of the lifting mechanism of the handling vehicle is simple. If the length of the handling vehicle is 4, the relative length of the rocker arm 3 is 31, and the relative length of the distance between the platform car bottom plate supports is 21, which is the rocker arm swing angle. Due to the need to analyze the dynamic performance and position analysis of the non lifting mechanism in Ge 3, it is simplified as a shaking block mechanism in Ge 4. shake
