The design of support points for selecting process parameters is to avoid energy consumption and noise generation due to collision between components and supports during vibration. The supports should be arranged near the nodal line, and the layout principle is: when the aspect ratio of the component is greater than 2, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.
The lifting stage is a high-altitude operation equipment, and prolonged use can cause loose connections between some components. So in order to ensure the personal safety of construction workers, it is necessary to regularly inspect the lifting stage and tighten any loose components.

So in order to ensure the personal safety of construction workers, it is necessary to regularly inspect the lifting stage and tighten any loose components. The interference and hazard analysis of the frequency conversion speed regulation construction elevator circuit is becoming increasingly widespread in the development of technology today. Variable frequency speed regulation has the characteristics of stable start and stop process, reducing mechanical shock, increasing the comfort of passengers and improving the service life. At the same time, it can also change the speed of power supply frequency regulation, save electric energy and improve work efficiency. However, there will be interference in the use of variable frequency speed regulation system, which will often cause safety accidents of construction elevator.
Thermal aging stress relief is generally suitable for small workpieces, while the lifting foundation structure has a large volume and does not have a large enough annealing furnace. Using natural aging takes one year and the production cycle is too long, so neither of these two methods is feasible. After research and understanding by the manufacturer, it was found that selecting appropriate support points for large welded structural components can perform vibration aging stress relief. Therefore, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!

The vibration frequency should be set to obtain large dynamic stress with low energy consumption and the resonance frequency should be used to handle time dependent vibration. However, and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration,YongjiAluminum alloy automatic lifting platform, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.

Check the wear and clearance condition of the guide wheel of the cargo elevator
The safety control voltage of 18 is selected with rolling guide shoes, high accuracy, wear resistance, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: 1. There is no need for a machine room above the shaft. 2. The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. 3. The load and load cylinder of the hydraulic elevator directly act on the foundation pit, and the strength requirements of the shaft are low, Brick or brick concrete structure hoistway can be used for Jinchuang lifting platform safety and stability advantages. Overflow valve: It can prevent system pressure from being too high during upward movement. Emergency manual valve: In case of power failure it can make the elevator emergency descend to the nearest floor position and open the door.
Yongji.Vibration aging treatment and effect judgment: According to the aging process plan, after setting the support points and vibration pickup points of the workpiece, use a rigid fixture to fix the exciter on the workpiece, and use the manual function of the equipment to test the vibration. It is determined that around 5300 revolutions is the resonance frequency of the component. The amplitude generated by the eccentric gear of the exciter in the fourth gear can meet the vibration processing requirements of the foundation seat, so the excitation force is selected as the fourth gear.
