What is the structure of the excavator?
Thoroughly inspect the surroundings and bottom of the locomotive in accordance with the following sequence: 1, whether there is oil, fuel and coolant leakage. 2, whether there are loose bolts and nuts?. 3 、 is there any broken wire, short circuit and loose joint of the battery in the electrical circuit?. 4, whether there is oil pollution?. 5, if there are rumors accumulation. Daily maintenance notice of daily inspection work is to ensure that the hydraulic excavator can be an important part in maintaining long-term efficient operation, especially for the self-employed, do the usual daily inspection work can reduce maintenance costs. First of all, around two laps to check the appearance of mechanical and mechanical chassis or unusual, and whether there is a rotary bearing oil flows out, and then check the braking device and bolt fastener track, tighten the screw, the change of the change in time, if you need to check the tire wheel excavator is whether there is abnormal, and pressure stability. Excavator bucket teeth to see whether there is greater wear, it is understood that the bucket teeth will greatly increase the wear and tear in the construction process of resistance, will seriously affect the work efficiency and increase the wear and tear of equipment parts. See if there is crack or oil leakage in the bucket and the cylinder. Check battery electrolyte to avoid below level line. The air filter is an important part of preventing dust from entering the excavator. It should be checked and cleaned frequently. Always check the fuel, lubricating oil, hydraulic oil, coolant, etc. whether to add or not, and choose the oil according to the requirements of the manual, and keep it clean. After starting check 1, whistle and all instruments are in good condition. 2, engine starting state, noise and exhaust color. 3 、 is there any leakage of oil, fuel and coolant?.
Excavator structure structure: the common excavator structure includes power device, work device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities, etc.. In appearance, the excavator consists of three parts: the working device, the upper rotating platform and the walking mechanism. According to its structure and use, can be classified as: track, tire, walking, full hydraulic, semi hydraulic, full rotation, non full rotation, universal, special type, articulated, telescopic arm and other types. A work device is a device that performs the task of digging directly. The utility model is hinged by three parts, such as an arm, a bucket rod, a bucket, etc.. Boom, landing, bucket expansion and bucket rotation are controlled by reciprocating double acting hydraulic cylinders. In order to meet the needs of various construction operations, excavators can be equipped with a variety of working devices, such as mining, lifting, loading, leveling, clamping, pushing the earth, hammer and other operating tools. The rotary and walking device is the body of a hydraulic excavator, and the upper part of the turntable is provided with a power device and a transmission system. The engine is the power source of the excavator. Most of the diesel is used in the convenient site or the motor. The transmission mechanism transfers the power of the engine to the hydraulic motor, hydraulic cylinder and other actuating elements through the hydraulic pump, and drives the working device to move, so as to complete various operations. Daily inspection of excavator: visual inspection should be done before starting the locomotive.
