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, 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,HengshuiTractive mobile elevator, 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.After cleaning, clean the filter and replace it with a new filter element before adding new oil. What adverse reactions may occur during the early use of hydraulic cargo elevators?Hengshui,Heavy load capacity: protective plate form: ° Or ° Interchangeable configuration rocker working angle: ° Drive method: hydraulic power unit drive or screw drive.Check 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 tightenedDongola,Check the protective cable condition of the cable guide frameEvery customer pays attention to the price of elevators, so how does the manufacturer calculate the price of elevators? In general, the manufacturer calculates the price of the elevator for customers based on the actual size, height, and carrying capacity of the on-site reserved opening provided by the customer Customers do not need to pay too much attention to the price difference between different elevator manufacturers when purchasing elevators, as the different materials used,HengshuiHydraulic aluminum alloy lifting platform, material brands, and production processes result in different prices for elevators Customers can consider the cost-effectiveness of elevators more when purchasing, with the principle of getting what they pay for. Safety hazard elimination plan for lifting cargo elevators: When there is a malfunction or abnormal situation in the lifting cargo elevator, it should be immediately stopped from use. After eliminating the malfunction and accident hazards, it can be put back into useCheck the safety interlocking equipment of the first cut door of the hanging cage

Leakage occurs due to looseness, vibration and the influence of heat on the sealing surface and pipe joints of the machine; Some casting, processing and other defects are difficult to detect during assembly and debugging, but due to vibration and impact during the operation process, these defects are exposed, manifested as oil (water) leakage. Therefore, leakage is prone to occur during the running-in period. Poor, it can cause scratches or bite on the friction surface of precision fitting oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces efficiency and causes early abnormal wear of the components. In severe cases, leading to the occurrence of faults.The safety control voltage of is selected with rolling guide shoes, high accuracy, wear resistance, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: . There is no need for a machine room above the shaft. . The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. . 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.　　Project scope,Check the protective cable condition of the cable guide frameCheck the smooth steel wire rope and various fasteners, if there is excessive wear, it is necessary to replace themCheck the wear condition of the pinion and rack please refer to the instruction manual for specific requirements

Many times, after installing hydraulic cargo elevators in factories,HengshuiGuide rail type lifting platform for factory use, floors, Yakali's editor summarizes some common problems with hydraulic cargo elevators and provides some statements on how to solve and prevent these problems.Statistics there may be some adverse reactions and problems in the early stage. Below,Ensure that power cables and electrical circuits are not damagedThe 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 , two point supports can be used; When the aspect ratio is close to , it is advisable to use or -point support.Knowledge of pressure lifting platforms, boarding bridges, mobile elevators, and more is available in Jiuheng, Jinan.
