Check the interlocking equipment, up and down travel, and other safety maintenance switches of the cage door and fence doorCheck the interlocking equipment, up and down travel, and other safety maintenance switches of the cage door and fence doorLouisville,The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T-, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.Attention: Abnormal meshing of gear teeth should be avoided: uneven rolling of the rollers should be avoided; Avoid diagonal orientation of the guide rollers; It should be avoided that the guide rollers are kept at the same time for a long time; The above abnormal phenomena can lead to rapid wear and even scrapping of gears, racks, rollers,LouisvilleCar mounted aluminum alloy lifting platform, and guide rails. If adjusted more carefully, it will be more beneficial for the service life of the elevator.Liege,Since the antirust paint on the exterior layer will actively react with the oxygen in the air, the reaction speed will be accelerated, so the exterior paint on the warehouse goods elevator will show signs of aging and then fall off every once in a while. Therefore, when maintaining the equipment of the lift table at ordinary times, pay attention to its storage, and try not to leave it outdoors, let alone in cool days or rainstormUse 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 requirementsLeakage occurs due to looseness, 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, due to the small fit clearance of newly assembled components and the difficulty in ensuring the uniformity of fit clearance due to assembly and other reasons, 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, it can cause scratches or bite on the friction surface of precision fitting, leading to the occurrence of faults.

Check the wear condition of the pinion and rack, please refer to the instruction manual for specific requirementsAccording to calculations, when the support points of the beam type components are located along the length of /L on both sides, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, and the structure is complex. Therefore two support points should be taken on each side for time treatment.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,LouisvilleTrailer folding arm lifting platform, 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.ranking,Manganese steel is generally used as the primary profile for warehouse cargo elevators. In order to achieve better anti-corrosion effect, a layer of rust resistant primer is usually applied, which effectively blocks air and prevents premature corrosion of the steel. Below, Ruilong hydraulic press will explain the role of rust resistant primer.Since the antirust paint on the exterior layer will actively react with the oxygen in the air, especially in the cold sun or rainstorm climate, so the exterior paint on the warehouse goods elevator will show signs of aging and then fall off every once in a while. Therefore, when maintaining the equipment of the lift table at ordinary times, pay attention to its storage, and try not to leave it outdoors, let alone in cool days or rainstormAdjust and correct various safety doors and mechanical interlocking equipment

Check the protective cable condition of the cable guide frameTest results,Check all standard sections and diagonal support connection points. Check the fastening bolts of the gear rack and ensure that the motor cooling wing plate and organization are cleanPower supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.　　?? 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 and carefully inspect the steel structure, safety protection devices, electrical devices, and transmission devices of construction elevatorsLouisville,Weekly maintenance: According to the operation instructions, ensure that the elevator is inspected and smooth every dayThe surface of each part of the brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than %.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.
