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,TextAluminum alloy single column lifting platform, so the excitation force is selected as the fourth gear.

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,TextOutdoor guide rail type lifting platform, 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.

Text.The lifting stage can provide real-time information on the operation of the entire vehicle, avoiding relying solely on the experience of operators to coordinate with each other, and it must be accurately calculated. The lifting stage has two structurally separate systems, the ground turntable and the high-altitude work bar. However, for various movements on the vehicle, it is also an interconnected system, which needs to consider the priority of operation system redundancy, and safety assurance of actions.

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

.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.

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.

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.

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

Ensure that power cables and electrical circuits are not damaged

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

Good reputation.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

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.

Honesty and mutual benefit.Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.

Weekly maintenance: According to the operation instructions, ensure that the elevator is inspected and smooth every day

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

02 The lifting platform adopts a fully hydraulic lifting mechanism, which can be operated inside the platform bucket and on the elevator body. 03 The working arm of the lifting platform can rotate 360 degrees. 04 The hydraulic system is equipped with a safety valve to prevent the main arm oil cylinder oil pipe from cracking. 05 The hydraulic legs are equipped with a hydraulic locking device to prevent the leg oil cylinder from retracting. 06 The hydraulic system is equipped with an automatic platform overload protection device, In order to ensure the safety of operators, each section of the working arm on the platform 07 is equipped with safety limit devices. The hydraulic system seals on the platform 08 are all well-known domestic and foreign brands, and the power of the entire vehicle 09 is a diesel engine with its own power supply. The power supply can also be used. The hydraulic lifting platform is equipped with an emergency lowering device in case of power outage. The 11 folding arm lifting platform product can also use a 50Hz, 380V power motor, and diesel engine dual power.

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, so 5366r/min was determined as the aging frequency.
