Gdansk. ?? 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.
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.
.Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.
Firstly, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.
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, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!
The safety control voltage of 18 is selected with rolling guide shoes, high accuracy,GdanskSelf propelled platform lifting, 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.
Transfer of goods between floors of rooms, restaurants, and restaurants. The low height is between 150-300mm, especially suitable for workplaces that cannot excavate pits. And there is no need for upper lifting points, with diverse forms (single column double column, four column), stable equipment operation, simple and reliable operation, economic and convenient goods transmission, and difficult to solve narrow spaces that cannot reach the requirements. A customized delivery platform can be created, and the product hydraulic system is equipped with anti fall, upper and lower door interaction, and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point. The product has a sturdy structure, a large load-bearing capacity, simple and convenient installation and maintenance, making it an ideal and economical cargo conveying equipment for replacing elevators between low floors. The lifting stage device is mainly responsible for data processing of the operation mechanism and work bar of the vehicle, calculating the safety area of the lifting stage, and is suitable for the electric control system of the self lifting stage lifting platform. The main sensors in the electric control system include angle sensors, long angle sensors, dual axis inclination sensors, and energy saving of the oil cylinder system.
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, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010 and the scope and space of operation are not affected.
Quality inspection report.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.
The selection of vibration pickup points refers to the placement point of the sensor, 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.
However,GdanskSelf walking aluminum alloy lifting platform, large welded structural components have the characteristics of complex morphology, 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, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.

Therefore, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH-700 vibration aging equipment, petroleum jelly which covers the metal surface of the aluminum alloy lifting platform with a protective layer to isolate the metal products from the surrounding corrosive medium and prevent corrosion. Apply engine oil, paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; Using electroplating, hot plating,GdanskScissor fork type self-propelled lifting platform, spray plating, etc., to coat the surface of steel with a layer that is not easily corroded
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.
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.
