FranceFixed hyand 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 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.
.Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.
However, large welded structural components have the characteristics of complex morphology,FranceScissor fork type self-propelled lifting platform, large weight, large differences in residual stress size and distribution, and it is difficult to achieve good results using ordinary vibration aging technology. Therefore, it is crucial to develop a reasonable process. Therefore, and requested us to develop a complete vibration aging process.
Emergency stop: Press the emergency button switch to raise or lower the machine.
Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
How to maintain and maintain the stage? When using the lifting stage in daily life,FranceFour pillar aluminum alloy lifting platform, 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, 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 there should be no dirt present, it must be replaced immediately.

Quality improvement.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.

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.
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.
Inspection basis.Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends it is driven by the pressure generated by its own weight, which greatly saves energy.
?? When the construction supervisory department fulfills its safety supervision and inspection responsibilities, it shall order the immediate elimination of potential safety hazards in the production of construction elevators and cargo elevators discovered during the inspection. If safety cannot be guaranteed before or during the elimination of major production safety hazards, it shall be ordered to evacuate workers from the hazardous area or temporarily stop construction. In the work of hazard investigation and control, the investigation shall be serious, the rectification shall be resolute, and the results shall be consolidated.
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, 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,FranceGuide rail vertical lifting platform, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation.
