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.
Huanghua.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, 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
Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.
.The driver shall close and lock the movable doors at both ends of the protective fence before work, and then ring the bell to start. It is strictly prohibited to work with the movable doors of the protective fence open. In case of special circumstances during platform operation, the emergency stop switch can be used to stop the platform. However, it is prohibited to use the emergency stop switch to stop the platform.
Thermal aging stress relief is generally suitable for small workpieces, 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 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,HuanghuaHydraulic aluminum alloy lifting platform, it is advisable to use or 4-point support.
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, there may be one or more resonance peaks in large components, 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 which slowly increases the speed of the excitation motor from 0, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.
How to maintain and maintain the stage? When using the lifting stage in daily life, attention should be paid to maintenance to extend its lifespan. Below, Jinan Dasheng Hydraulic Machinery will introduce several maintenance and attention points for everyone: the brakes of each mechanism should be regularly inspected and adjusted for the clearance between the brake pads and wheels to ensure flexibility and reliability. On the friction surface, there should be no dirt present, and any dirt must be washed off with gasoline or thinner. Pay attention to checking each steel wire rope for broken wires and loose strands. If it exceeds the relevant regulations, it must be replaced immediately. Professional elevator manufacturers have a complete range of products, which are popular both domestically and internationally. Our equipment has a long service life! The industry leader in product wire products, welcome to inquire
Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
Convenient and efficient.Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.
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
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,HuanghuaHydraulic turnover machine, it is necessary to perform stress relief treatment on the completed components.

Customer first.Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.
Check if the orientation of the upper and lower limit blocks on the guide rail frame is correct
Emergency stop: Press the emergency button switch to raise or lower the machine.
Huanghua.Firstly, 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, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.
