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, 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.

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, during normal operation it is prohibited to use the emergency stop switch to stop the platform.

Rostock.　　?? Hidden danger investigation relies on joint efforts from all aspects:?? Construction enterprises are the main responsibility for identifying hidden dangers in construction elevators. They should strengthen daily inspections and regular inspections, and carefully inspect the steel structure, safety protection devices, and transmission devices of construction elevators

According to the scanning curve, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.

.Firstly, 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.

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.

Applicable environment: Indoor or outdoor Applicable temperature: Safety device Safety rocker: When the equipment is running and rising, the rocker will automatically prevent wheelchair platform.

Emergency stop: Press the emergency button switch to raise or lower the machine.

Regularly check all wires and cables for damage. Timely bandage and replace damaged parts.

Drivers should be responsible for supervising the uniform distribution of items transported by the platform on the platform as much as possible to prevent partial loading and prohibit overloading. flat

Recommendation and consultation.Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.

When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.

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.

Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.

device management.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.

Every customer pays attention to the price of elevators, so how does the manufacturer calculate the price of elevators? In general, the manufacturer calculates the price of the elevator for customers based on the actual size, height, and carrying capacity of the on-site reserved opening provided by the customer Customers do not need to pay too much attention to the price difference between different elevator manufacturers when purchasing elevators, as the different materials used, material brands, and production processes result in different prices for elevators Customers can consider the cost-effectiveness of elevators more when purchasing with the principle of getting what they pay for. Safety hazard elimination plan for lifting cargo elevators: When there is a malfunction or abnormal situation in the lifting cargo elevator, it should be immediately stopped from use. After eliminating the malfunction and accident hazards, it can be put back into use

Emergency stop: Press the emergency button switch to raise or lower the machine.
