ChengdeAluminum alloy automatic lifting platform,

The frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit. The main circuit is mainly composed of a construction lifting cargo elevator (hereinafter referred to as the lifting cargo elevator) driven by a more complex rectifier. Before installation, all the eccentric roller shafts of the lifting cage and driving mechanism are loosened or adjusted to a large eccentricity. The lifting cage and driving mechanism are installed in the guide rail frame respectively, power on the suspension cage to lift it m above the ground or detach it from the ground buffer spring (or support). The adjustment and sequence are as follows: . Use a special wrench to rotate the lower double (single) pendulum eccentric shaft to adjust the eccentricity to ensure that the installation plate surface of the driving mechanism is perpendicular to the horizontal plane, use a feeler gauge to measure the side clearance to .; Between .mm each pressing wheel should evenly press on the back of the rack. Move each wheel body by hand to check if it evenly presses against the tooth back. Similarly, adjust the guide rollers on both sides of the guide rail. The adjustment key is to adjust the guide wheel on one side of the guide rail to lightly press it onto the guide rail. When moving the wheel body by hand, it should be possible to rotate but there should be obvious obstruction; The roller on the other side should maintain a clearance of .-. ram with the guide rail; . Adjust the lifting cage according to the above and sequence. If the driving mechanism and the lifting cage are integrated into the lifting cargo elevator, the lifting cage should be adjusted according to the and sequence of adjusting the driving mechanism. Conduct a visual inspection of the operation of each roller, and use the lead pressing method and coloring method to check the meshing of the gear pair; Fine tune pairs of unsatisfactory parts. The key point is to carefully adjust the meshing status of the gear pair: when the spots shown in appear on the surface of the gear rack, it indicates that the driving mechanism is tilted towards the side of the guide rail. At this time, the lower swing wheel (single or double wheel) should be adjusted to move the lower part of the driving mechanism towards the direction of the guide rail until the area of the spots reaches more than % of the surface of the gear rack. The smaller the area, the easier it is to damage the gears and racks.Ensure that power cables and electrical circuits are not damagedChengde,The 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, spray plating, etc. on the surface of steelWhen installing, disassembling, and adjusting the rotating mechanism, it is important to ensure that the centerline of the reducer of the rotating mechanism is parallel to the centerline of the gear, and its meshing surface is not less than %. The meshing clearance should be suitable for each box, distribution box, etc., and should be kept clean regularly. Dust on electrical equipment should be cleaned in a timely manner. When encountering overheating in the electric motor, and the hydraulic cargo elevator should provide us with safety protection. The application of hydraulic cargo elevators in our production is already very common, and plays an important role in our production especially in high-altitude operation of goods.Poprad,Knowledge of pressure lifting platforms, mobile elevators, and more is available in Jiuheng, Jinan. We sincerely welcome colleagues from all walks of life to visit and inspect the factory, cooperate and negotiate, and seek common development. The following maintenance and upkeep are required for the lifting cargo elevator: Maintenance and upkeep: Maintenance and upkeep should be carried out by the equipment operator or full-time personnel of the operating unit. The equipment maintenance and upkeep unit is responsible for supervising and reviewing the maintenance content. The main content of maintenance and upkeep is summarized as follows:; quot; Cross operation method; quot;: Clean, tighten,ChengdeCurved arm lifting platform, smooth, adjust, and prevent corrosion. Before and at the end of each shift, to minutes before and after each day, inspect all parts and components of the equipment to ensure they are normal. Apply oil smoothly according to rules, pay attention to the sound of mechanical operation, and do a good job in cleaning and handover to achieve the goal of clean appearance and normal operation of the equipment. Maintenance and handover records should be made in a fixed form and used for managementClean and inspect the crown wheel frame assembly, correct or replace with new partsAdjust and correct various safety doors and mechanical interlocking equipment

　　?? 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, safety protection devices, electrical devices, and transmission devices of construction elevatorsPower supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.On the contrary, 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 the guide roller should be loosened for o and then adjusted according to the adjustment of the guide roller.system,The cleaning oil for the hydraulic system must use hydraulic oil of the same brand as the system used, with an oil temperature between and ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more. After each cleaning, fully drain the system while the oil is hot.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, 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.Regarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel, and the counterweight steel wire rope bracket
