Grosseto.The frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit. The main circuit mainly consists 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, and 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 until it rises 1m above the ground or detaches from the ground buffer spring (or support), the adjustment and sequence are as follows: 1. Use a special wrench to rotate the lower double (single) pendulum eccentric shaft to adjust the eccentricity to maintain the installation surface of the mechanism perpendicular to the horizontal plane, and make the upper and lower pendulum wheels evenly guide the rails at the same time. Rotate each wheel body by hand to check if it evenly presses the rails; 2. 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, use a feeler gauge to measure the side clearance to 0.2; Between 0.5mm, 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,GrossetoDouble column aluminum alloy lifting platform, 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 0.2-0.5 ram with the guide rail; 4. 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, and use the lead pressing method and coloring method to check the meshing of the gear pair; Fine tune 6 pairs of unsatisfactory parts. The key point is to carefully adjust the meshing status of the gear pair: when the spots shown in 1 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 85% of the surface of the gear rack. The smaller the area, the easier it is to damage the gears and racks.

The driver shall close and lock the movable doors at both ends of the protective fence before work and then ring the bell to start. It is strictly prohibited to work with the movable doors of the protective fence open. In case of special circumstances during platform operation, the emergency stop switch can be used to stop the platform. However, during normal operation, it is prohibited to use the emergency stop switch to stop the platform.
Knowledge of pressure lifting platforms, boarding bridges, 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:; amp; quot; Cross operation method; amp; quot;: Clean, tighten, smooth, adjust, and prevent corrosion. Before and at the end of each shift, 10 to 30 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 management
Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.

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.
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.

Grosseto.According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.
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, spray plating,Grosseto8-meter aluminum alloy lifting platform, etc.,Grosseto10 ton mobile boarding bridge manufacturer, high accuracy, 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.
