Regarding the construction elevator with counterweight, the crown wheel, it is necessary to replace themJinyuan,Firstly, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, adding chromium, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.The wear rate is fast, and due to factors such as processing, assembly, and adjustment of new machine components, the friction surface is rough, the mating surface area is small, and the surface pressure condition is uneven. During the operation of the machine, the concave and convex parts on the surface of the parts are intertwined and rubbed against each other. The metal debris that falls off from the grinding process, in turn, acts as abrasive and continues to participate in friction, further accelerating the wear of the mating surface of the parts. Therefore, during the running-in period, it is easy to cause wear on components (especially the mating surface), with a fast wear rate. At this point, if overloaded, it may cause damage to the components and lead to early failures.Talagante,Check the interlocking equipment, up and down travel, and other safety maintenance switches of the cage door and fence doorAll connecting shafts must have split pins and be sufficient.Many times, after installing hydraulic cargo elevators in factories, floors,JinyuanAluminum alloy hydraulic lifting platform, docks, and other places, there may be some adverse reactions and problems in the early stage. Below,JinyuanAluminum alloy lifting platform double columns, Yakali's editor summarizes some common problems with hydraulic cargo elevators and provides some statements on how to solve and prevent these problems.

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 bracketDrivers should be responsible for supervising the uniform distribution of items transported by the platform on the platform as much as possible to prevent partial loading and prohibit overloading. Platform does not allowAfter cleaning,Check the wear condition of the pinion and rack,JinyuanHydraulic aluminum alloy hydraulic lifting platform, please refer to the instruction manual for specific requirementsAll connecting shafts must have split pins and be sufficient.Check and repair the electrical circuit and control panel switch components. If there is aging in the circuit, replace it

Monthly maintenance: View weekly inspection itemstechnological innovation,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 boltsThe arrangement of vibration points should be based on the vibration aging process standard GB/T-. The vibration aging exciter should be placed at a position with high rigidity and amplitude of the workpiece, and its rotating axis should be parallel to the plane where the effective zone of the vibration mode is located. The exciter should be fixed at the end angle or edge of the workpiece with high rigidity so that small energy can be used to excite the component with large amplitude. Based on the structural shape of the foundation, we set the vibration points on the protruding plates on each side of the workpiece.Check the relative orientation between the cable support wall and the cable guide frameJinyuan,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, 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.Check the safety interlocking equipment of the first cut door of the hanging cageCheck if the usage period of the speed limiter has expired. If it exceeds the usage period, it is necessary to send it to a qualified professional unit for inspection and calibration. What are the functions of the lifting stage device?
