The reduction gearbox, gearbox, external meshing gear and other parts, as well as the hydraulic oil, are all carried out according to the requirements in the table.Check the smooth steel wire rope and various fasteners, if there is excessive wear, it is necessary to replace themEmen,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 , 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 r/min, so r/min was determined as the aging frequency.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 improving the reliability and safety of the system. The definition of safety zone is very important because the lifting stage has a large range of movements, and it must be accurately calculated. The lifting stage has two structurally separate systems, the ground turntable and the high-altitude work bar. However,EmenSelf-propelled lifting platform, 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.Hammersmith and Fulham, it should be adjusted in the opposite direction; When the meshing backlash of the gear pair is greater than .mm, loosen the connecting nut of the eccentric shaft of the guide roller and the tooth back pressure wheel as shown in , adjust the tooth back pressure wheel to press towards the back plane of the gear rack until the backlash reaches a reasonable range. Otherwise, it should be adjusted in the opposite direction. At this point, newly processed and assembled components have deviations in geometric shape and fitting dimensions. In the early stages of use, due to alternating loads such as impact and vibration as well as factors such as heat and deformation, coupled with rapid wear and tear, it is easy to cause the previously fastened components to loosen.Regularly check whether the operation of each mechanism is normal and whether there is any noise. If any faults are found, they must be promptly eliminated.

　　?? Hidden danger investigation relies on joint efforts from all aspects:?? Construction enterprises are the main responsibility for identifying hidden dangers in construction elevators. They should strengthen daily inspections and regular inspections, and carefully inspect the steel structure, electrical devices,EmenScissor fork type mobile lifting platform, and transmission devices of construction elevatorsThe second method is the protective layer method, 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, petroleum jelly paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; It is not easy to apply a layer of electroplating, hot plating, etc. on the surface of steelCheck the safety interlocking equipment of the first cut door of the hanging cageDirect labor,Check the relative orientation between the cable support wall and the cable guide frameRegularly check the connection of each part and tighten it if there is any looseness. The tightness of the body connecting bolts should be checked when the body is under pressure (the rotating arm can be used to cause compression)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, it will be more beneficial for the service life of the elevator.

Ensure that the small gear and pressure wheel are securely fastened on the drive base plate, and check the fixing condition of the drive base plate boltsreform,Organize, remove rust and repaint the structural components such as the suspension cage and guide rail frame for corrosion, and reinforce the severely corroded load-bearing membersThe 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.
