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, and the two are connected. Starting from adjusting the driving mechanism, 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, and ensure that the upper and lower pendulum wheels evenly guide the rails at the same time. Use your hand to move each wheel body and check if it evenly presses the rails; . Use a special wrench to rotate the eccentric shaft of the gear rack back pressure wheel to adjust the side clearance during gear rack meshing. When adjusting, 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,UptarAutomatic aluminum alloy lifting platform, 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.quality,The lifting stage is a high-altitude operation equipment, and prolonged use can cause loose connections between some components. So in order to ensure the personal safety of construction workers, it is necessary to regularly inspect the lifting stage and tighten any loose components. The lifting stage is a high-altitude operation equipment, and prolonged use can cause loose connections between some components. So in order to ensure the personal safety of construction workers, it is necessary to regularly inspect the lifting stage and tighten any loose components. The interference and hazard analysis of the frequency conversion speed regulation construction elevator circuit is becoming increasingly widespread in the development of technology today. Variable frequency speed regulation has the characteristics of stable start and stop process, reducing mechanical shock, increasing the comfort of passengers, and improving the service life. At the same time, it can also change the speed of power supply frequency regulation,UptarMobile boarding bridge Mobile boarding bridge, save electric energy, and improve work efficiency. However, there will be interference in the use of variable frequency speed regulation system, which will often cause safety accidents of construction elevator.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.Check the wear condition of the pinion and rack, please refer to the instruction manual for specific requirementsUptar,When 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, it is necessary to stop it in a timely manner and troubleshoot before continuing to operate. The motor bearings should be in good condition, 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.Use a feeler gauge to check the wear condition of the worm gear of the worm gear reducer. Please refer to the instruction manual for specific requirementsCheck the fastening status of the wall bracket, support rod, and bolts and retaining rings between the lifting cargo elevator and the bridge. If they are loose or displaced, they should be checked and tightened
