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,San Severo Self moving lifting platform, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.
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,San Severo Single rail lifting platform, 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.
San Severo .Drop test to check if the braking interval of the safety governor meets the requirements of the rules. Equipment transfer maintenance: Check the coupling between the electric motor and the worm gear reducer, and dismantle the gearbox. Clean all components and seals, replace excessively worn and deformed parts and smooth oil
The arrangement of vibration points should be based on the vibration aging process standard GB/T25712-20. The vibration aging exciter should be placed at a position with high rigidity and amplitude of the workpiece, and its rotating axis should be parallel to the plane where the effective zone of the vibration mode is located. The exciter should be fixed at the end angle or edge of the workpiece with high rigidity, so that small energy can be used to excite the component with large amplitude. Based on the structural shape of the foundation, we set the vibration points on the protruding plates on each side of the workpiece.
.The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.
According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.
Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.
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, filter cover, inspection hole, hydraulic oil pipe and other parts, it is necessary to avoid dust during the system oil passage. The disassembled parts must be thoroughly cleaned before opening. When disassembling the hydraulic oil tank filler cap, first remove the soil around the tank cap. After loosening the tank cap, remove any remaining debris from the joint area (do not rinse with water to prevent water from seeping into the tank). Only after confirming cleanliness can the tank cap be opened. When using materials and hammers, materials that do not remove fiber impurities and specialized hammers with rubber attached to the surface should be selected. Hydraulic components and hydraulic hoses should be carefully cleaned, dried with high-pressure air, and then assembled. Choose a well packaged filter element (the inner packaging is damaged, although the filter element is intact, it may also be unclean). When changing the oil clean the filter at the same time. Before installing the filter element, carefully clean the bottom dirt inside the filter housing with materials.
Now with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?
technical service.The lifting foundation of the platform is a large structural component made of alloy steel plates with different thicknesses that are welded together. The welding amount is large, the structural shape is complex, and residual stress is inevitably generated during the manufacturing process. In order to prevent deformation of the components due to changes in residual stress during use, it is necessary to perform stress relief treatment on the completed components.

Folding arm lifting platform product features 01 Folding arm lifting platform High altitude operation platform 360 degree rotation without external power supply, can work across obstacles, lifting smoothly and safely. The curved arm lifting platform adopts a curved arm working arm, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, adding chromium, nickel, changing the internal structure of the metal to prevent rust.
There are many operational errors, and due to insufficient understanding of the structure and performance of the machine (especially for new operators), it is easy to cause malfunctions and even mechanical accidents due to operational errors. How to calculate the lifting cargo elevator? A lifting cargo elevator is a heavy lifting mechanical equipment that can manually operate the system's buttons to complete the transportation of goods up and down. The lifting height of the lifting cargo elevator varies from 1 meter to 20 meters, and special specifications of lifting and lowering cargo elevators can be customized according to user requirements According to the type, it can be divided into:; Scissor fork type cargo elevator and guide rail type cargo elevator. Guide rail type elevator is a non scissor fork type cargo elevator, mainly used for the transportation of goods between floors of workshops, steel structure workshops, hotels, rooms, and warehouses without pits or machine rooms. Scissor fork type cargo elevators need to be prepared with pits before installation, and the elevator should be fixed and connected in the pit before being connected to the power supply The lifting cargo elevator utilizes hydraulic power units to generate pressure during operation, which drives the hydraulic oil cylinder as the main power to raise and lower the lifting cargo elevator platform. When a guide rail type hydraulic lifting cargo elevator malfunctions, it can immediately stop running, with high safety and stability. The driving of the hydraulic power unit makes it have strong load-bearing capacity and smooth lifting, which can achieve the transportation of large tonnage goods
The second method is the protective layer method, which covers the metal surface of the aluminum alloy lifting platform with a protective layer to isolate the metal products from the surrounding corrosive medium and prevent corrosion. Apply engine oil, petroleum jelly, paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; Using electroplating hot plating, spray plating, etc., to coat the surface of steel with a layer that is not easily corroded
