SeattleVerticaThe 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 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, especially in the cold sun or rainstorm climate, the reaction speed will be accelerated, so the exterior paint on the warehouse goods elevator will show signs of aging and then fall off every once in a while. Therefore, when maintaining the equipment of the lift table at ordinary times, pay attention to its storage, and try not to leave it outdoors, let alone in cool days or rainstorm
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.

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.
Low failure rate: Due to the use of advanced hydraulic systems and good methods, it is driven by the pressure generated by its own weight,SeattleSelf propelled tracked scissor fork lifting platform,SeattleMobile lifting platform, which greatly saves energy.
Attention: Abnormal meshing of gear teeth should be avoided: uneven rolling of the rollers should be avoided; Avoid diagonal orientation of the guide rollers; It should be avoided that the guide rollers are kept at the same time for a long time; The above abnormal phenomena can lead to rapid wear and even scrapping of gears, racks, rollers, and guide rails. If adjusted more carefully, 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.
Range.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?
When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.
Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.
According to calculations, when the support points of the beam type components are located along the length of 1/9L on both sides, the vibration resistance is relatively small making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
Latest quotation.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,SeattleAluminum alloy hydraulic lifting platform, 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.

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.
Seattle.During aging treatment, the equipment prints the vibration aging curve online. According to the curve, the front end of the a-t curve shows an upward trend, indicating that the damping inside the component decreases after vibration treatment, so the amplitude gradually increases; Since then, the amplitude change has been basically stable, indicating that the structure of molecules inside the component tends to be stable, which conforms to the judgment standard of curve observation strip, thus it can be determined that the workpiece has reached the effect. The precautions for using an electric lifting platform are as follows: the user unit should arrange a dedicated person to operate the lifting platform and develop details and safety precautions for the use of the lifting platform based on their own unit's situation, and hang it in a prominent position. When working on an electric lifting platform, professional drivers and operators must be equipped, and they must undergo specialized training and be qualified. They must hold relevant certificates and take on corresponding responsibilities according to the actual situation of the work. After the construction is completed, the lifting platform needs to be moved on the site and should be operated by a professional driver. Before daily work, zy12 drivers must carefully check the electrical, hydraulic, and mechanical systems of the platform, check the working range of the lifting platform truck, and remove obstacles that hinder the rotation and walking of the lifting platform truck. And empty the platform up and down several times to check for any faults or abnormal phenomena. It is also necessary to pay attention to the accuracy of the platform platform landing station for any obvious abnormal differences.
