Vitti sur SeineCar mounted aluminum alloy lifting platformWhat are the detection methods

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,Vitti sur SeineMobile lifting platform, the vibration pickup point is set in a thick area in the middle of the component.

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.

However, large welded structural components have the characteristics of complex morphology, large differences in residual stress size and distribution,Vitti sur SeineFixed guide rail lifting platform,Vitti sur SeineVertical obstacle free lifting platform, and it is difficult to achieve good results using ordinary vibration aging technology. Therefore, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.

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

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, the rocker will automatically prevent wheelchair platform.

Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.

Equipment maintenance.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, it is advisable to use or 4-point support.

Folding arm lifting platform product features 01 Folding arm lifting platform High altitude operation platform 360 degree rotation without external power supply, can work across obstacles, lifting smoothly and safely. The curved arm lifting platform adopts a curved arm working arm, and the scope and space of operation are not affected.

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.

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

Check the protective cable condition of the cable guide frame

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

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

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, so the excitation force is selected as the fourth gear.
