When the height of a construction building exceeds meters， a -meter-wide safety net must be erected on the outside of the working face along with the construction layer. A fixed safety net must be erected on the first layer until there is no high-altitude operation.
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. Start by adjusting the driving mechanism by electrically driving the suspension cage up to m above the ground or off the ground buffer spring (or support). The adjustment sequence is as follows: . Use a special wrench to rotate the eccentric shaft of the lower double (single) swing wheel to adjust the eccentricity to keep the installation surface of the mechanism perpendicular to the horizontal plane， and make the upper and lower swing wheels evenly contact the guide rail at the same time. Rotate each wheel body by hand to check if it evenly presses the guide rail; . 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， the lifting cage should be adjusted according to the and sequence of adjusting the driving mechanism. Conduct a visual inspection of the contact and operation of each roller， and use the lead pressing method and coloring method to check the meshing condition 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 contact spot shown in appears on the contact 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 contact spot reaches more than % of the contact surface of the gear rack. The smaller the contact area， the easier it is to damage the gears and racks.

xsan diego Hydraulic elevator hydraulic system search Based on the hydraulic elevator hydraulic system search for hydraulic pump hydraulic faults， when analyzing and troubleshooting the hydraulic system， the main task is to; Grab both ends&# quo& mdash;& Flash; That is， the power source (oil pump) and the actuator (cylinder， electric motor)， followed by; Even in the middle;， The pipelines and components that pass between the power source and the actuator& ldquo; Grab both ends&# quo; When analyzing， it is necessary to determine whether the fault lies in the oil pump， cylinder， and motor themselves& ldquo; Connect to the middle” In addition to paying attention to analyzing whether the fault is caused by the hydraulic components on the connected circuit， special attention should also be paid to figuring out which method the system uses when transitioning from one working state to another， whether the signal is incorrect， and checking each physical object one by one. Attention should be paid to whether there is any mutual interference phenomenon between the main oil circuits and between the main oil circuits， if there is any mutual interference phenomenon， To analyze how to use adjustment errors etc.
qVThe cargo elevator operator needs to conduct a daily inspection of the cargo elevator to ensure that there are no faults， and record the inspection results in the Daily Inspection Form of Cargo Elevator.
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 lubrication， 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， lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces lubrication 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.
