Explain the precautions for the chassis maintenance of aerial vehicles
The aerial work platform is a new generation of folding arm lifts. Can be widely used in stations, docks, airports, hotels, post and telecommunications, municipal gardens, grain storage, cleaning companies, public buildings facade decoration, decoration or power system installation and maintenance, and so on. The elevator has the advantages of light weight, self-propelled running, electric starting, self-supporting legs, simple operation, large working surface, free rotation of 360 degrees, and especially high-altitude operations that can overcome obstacles. Can be suitable for outdoor operations, using diesel as a power. It is also possible to use batteries as the walking and working power of the machine as required. The author stated that in the maintenance of aerial vehicles , the maintenance of the chassis is the most tense, but many users do not know to value this point, people who use the car know that the car is rotten, and the chassis ensures the quietness of the vehicle and the owner. Rusted, the structure of the vehicle will be loose, which is related to the life safety issues of high-altitude workers. Therefore, the maintenance of the chassis of the aerial work vehicle can not be sloppy, and many traffic accidents are caused by the looseness of the chassis. Below, the author will explain to the users of high-altitude aerial vehicles the method and significance of the chassis maintenance of aerial work vehicles. First, the chassis should be washed frequently and rinsed clean. Normally, anti-rust primers are sprayed on overhead vehicles , but they will gradually oxidize after a certain period of time. Armor is basically strengthening the chassis and thoroughly washing the chassis, and then spraying the chassis with elastic plastic material. To protect the chassis. The baking from the earth's surface, the invasion of rainwater, and the moisture and salt in the atmosphere are the causes of deterioration. The non-stop impact of sand on the road will also make the anti-rust paint on the chassis of the special car destroyed, so that the metal will be bare on the appearance of the chassis, and will quickly snuggle with moisture to produce oxidation and rust. In this way, it is necessary to remove chassis attachments such as tires, brake pads, etc., and thoroughly clean the bottom of the vehicle. This is to prevent impurities from adversely affecting the chassis. After drying, wrap the non-sprayed parts and spray the anti-rust primer several times. Second, check the brake system of aerial vehicles . Visually observe the appearance of the brake disc through the tire aluminum alloy steel ring. The appearance of the brake disc was originally smooth, and if there were obvious grooves, it was probably when the aerial vehicle was driving on the gravel road. Some tiny sand and gravel stuck between the brake disc and the fender, constantly rubbing the appearance of the brake disc. As a result, grooves appear. When this kind of environment arises, the high-altitude vehicle may give out a voice of “when it's right and wrong†when walking. In some circumstances, owners will also hear screams when they are dragging the brakes. Third, check the powertrain, transmission system with or without oil. There are several major components (such as engine, gearbox, rear axle, etc.) with or without oil leakage. Fourth, the test content Check whether the appearance of tire tread pattern is normal (such as whether there is a crack, whether there is a foreign body). Fifth, check whether the vehicle is full of oil and water and whether the oil quality is good. The contents include the engine oil of the aerial work vehicle, the coolant, the transmission, etc. If the liquid level is not enough, the change will be made if the oil quality is not good. During the operation of high-altitude vehicles, many components are in a very harsh operating environment: high temperature, high speed, dusty, bumpy roads, etc. Some parts are constantly worn due to frequent high-speed movements, and other parts are also When you inadvertently bruise, it requires timely inspection, adjustment or replacement. The author believes that regular maintenance of aerial work vehicles is mainly based on inspections and adjustments. Regular inspections of brakes, steering, transmission, and suspension systems are provided for each type of maintenance, so that they can have a safe driving environment. Through regular Inspection and maintenance can also find and solve existing hidden troubles and faults in time, and avoid the occurrence of even bigger faults. "Jin Yuankang three alloy electroplating technology refers to the double plating covering three element alloy thin, of which three yuan alloy copper tin Zinc Alloy" refers to the "three element alloy and stainless steel similar appearance". The coefficient of resistance is 1.7 cm (RF-10 GHz), the conductivity of (106S/m) (RF-10 GHz), the contact resistance is less than 10m at cN 100, with the help of a number of micro active flux solderability. Jin Yuankang ternary alloy electroplating for high frequency connection, in a wide frequency range the maximum transfer rate requirements, in addition, the "Three Element Alloy Plating technology can make the RF devices in industrial gases, perspiration and other corrosion or scratch, keep good appearance, without the protection of the silver coating even in normal circumstances rapid oxidation. "Three alloy plating technology" combines the excellent electrical conductivity of silver and the corrosion resistance of the alloy with "three elements", and the thin coating of the alloy with the value of in the range of 10GHz does not affect the good conductivity of silver. "Three alloy plating technology" does not contain magnetic elements, "plating alloy technology of three yuan" to prevent surface oxidation and film, the use of the surface will not lose luster. The characteristics of three element alloy plating surface to prevent scratches, not sensitive to damage, but also to prevent the silver plated cold welding and assembling with good damage caused by non. Compared with the silver plating, the "three element alloy technology" in the assembly of the device is especially to reduce the loss caused by the collision.
